    Title: Saddle adjustment device
    BACKGROUND OF THE INVENTION
    FIELD OF THE INVENTION
    The present invention relates to saddle adjustment technology, and more particularly to a saddle adjustment device for a folding bicycle that can offer a multi-height adjustment and secure fixation function.
    Description of the prior art
    Conventional bicycle saddles are all mounted on an upper end of a seat post that is inserted into a bicycle frame, and the bicycle frame is provided with a seat post clamp for clamping the seat post to fix the seat post.
    When the height of the saddle needs to be adjusted, the seat post clamp must first release the seat post, and then the height of the seat post protruding from the bicycle frame can be adjusted, and after the saddle has been adjusted to a desired height, the seat post clamp finally clamp the seat post again to fix the seat post on the bicycle frame.
    The existing bicycle frames, however, have different styles, and this is particularly so for folding bicycles, since folding bicycles must take into account the volume after being folded to facilitate carrying, and therefore there are various frame shapes.
    Referring to Figure 1, a conventional triangular bicycle frame 8 essentially comprises a front bar 81, a saddle bar 82, and a bottom bar 83 hingedly connected to each other. The top end of the saddle bar 82 is pivotally connected to the top end of the front bar 81, and the bottom end of the saddle bar 82 is pivotally connected to a rear wheel 84 and a rear end of the bottom bar 83 while the front end of the bottom bar 83 is mounted on a mounting seat 811 on a lower part of the front bar 81. The bottom end of the front bar 81 is connected to a front fork 812 to be hinged on the front wheel 85. The top end of the front bar 81 is provided with a handlebar 86, and the middle part of the bottom bar 83 is provided with a chain ring 87 which has a pair of cranks 88 and a pair of pedals 881. The chain ring 87 is connected by a belt 871 for driving to a smaller chain ring 89 which is mounted on the rear wheel 84. The saddle bar 82 is furthermore provided with a saddle mechanism 9. A folding bicycle is formed by such an arrangement.
    The saddle mechanism 9 comprises a saddle body 91 which is slightly L-shaped and slidably engages the saddle rod 82. The upper end of the saddle body 91 is provided with a saddle 92.
    When no external force is applied between the saddle body 91 and the saddle bar 82, the saddle body 91 and the saddle bar 82 are in a loose fit state. The saddle body 91 is provided with two saddle bar clamps 93 for clamping the saddle body 91 on the saddle bar 82 '. The saddle bar 82 is provided with a bolt 94, one end of which protrudes from the saddle bar 82, and the saddle body 91 is defined with a plurality of engagement grooves 95 corresponding to the bolt 94.
    When the two saddle bar clamps 93 are released, the respective engagement grooves 95 will form recesses for inserting the bolt 94, and when the two saddle bar clamps 93 are attached, the engagement grooves 95 will be forced to fix the bolt 94 fixedly.
    In other words, the saddle mechanism 9 can be positioned at a desired position through the cooperation of the bolt 94 with the engagement grooves 95, and the saddle body 91 is clamped on the saddle bar 82 by the two saddle bar clamps 93, thus adjusting the position and fixing of the saddle body 91 is realized.
    Nevertheless, in view of the light weight and the cost of the saddle mechanism 9, is. the above-mentioned saddle body 91 made of structural plastic, but the structural plastic is still not rigid enough despite the fact that it has high strength, so that when saddle body 91 is clamped onto saddle bar 82 by saddle bar clamps 93, saddle body 91 itself made of structural plastic will be compressed to cause elastic deformation. As a result, the resulting clamping force is less than the clamping force exerted on the metal saddle bar by the conventional metal frame, that is, when the saddle body 91 carries the weight of the cyclist, the saddle body 91 clamped by the two saddle body clamps 93 will still slip slightly .
    Normally, a clearance difference between a loosened saddle bar clamp and a fixed saddle bar clamp is only about 1 to 2 mm, but the change in clearance should allow the engagement grooves 95 to define a clearance between them for allowing the bolt 94 to pass, so that the engagement portion of the engagement groove 95 for the bolt 94 only has a depth of 1-2 mm. Since the bolt 94 is cylindrical, the contact surface between the engagement groove 95 and the bolt 94 is rather limited, and since the saddle body 91 is made of structural plastic, when the saddle body 91 carries the weight of the cyclist and relative to the saddle bar 82, the bolt 94 is forced to disengage from the engagement groove 95, thereby nullifying the positioning perception. If such a situation occurs frequently, the engagement groove 95 will be damaged to cause permanent deformation, whereby the positioning effect is lost.
    The present invention has arisen to weaken and / or remedy the aforementioned disadvantages.
    Summary of the invention
    The primary object of the present invention is to provide a saddle adjustment device that includes an engagement assembly that is capable of moving in a direction vertically to the axial direction of the seat tube and positioning the saddle body on the seat tube by engaging the protruding projections. use parts of the engagement assembly in the engagement grooves of the saddle body and the saddle tube clamp to clamp the saddle body on the saddle tube in order to provide a multi-height adjustment and secure fixation function.
    The secondary object of the present invention is to provide a saddle adjusting device which is provided with a penetration part on the saddle body corresponding to the saddle tube clamp, two half rings are formed at the penetration part, and the saddle tube clamp can be used to connect the two half rings with certainty.
