Description

• M322356 VIII. New Description: [New Technology Field] This creation is about a bicycle seat cushion, especially a kind of block that provides the topping force, which can make the bicycle seat cover and the self-a frame. Secure the sleeve of the bicycle seat cushion. [Prior Art] The combination of the general bicycle seat cushion and the frame is mostly after the bottom of the seat cushion is inserted into the frame, and then the bolt is used by the vehicle. The shortcomings of the form are as follows: For a sporty bicycle with a long straight body speed, it must be streamlined to minimize windage, and the exposed tamping member will increase the wind resistance. ―, the locking force is not good, it is easy to cause loose

The number of bolts will be tied to the right = the right is the same as the locking force and the increase in the dynamic bicycle " make the weight increase, which is not conducive to the competition for the use of the 456 when the tightening is 'easy to cause the frame or the pole to suffer damage. This leads to a complicated structure of the frame. Destroy the aesthetic appearance of the car body. The rider touches or is hooked, causing human injury or its [new content] 5 M322356 In view of the lack of prior art, the purpose of this creation is to propose a bicycle seat cushion set lever, which provides a topping by the slider Xianli can make the bicycle seat cover rod and the bicycle frame securely nested. In order to achieve the above object, the present invention proposes a self-propelled rod comprising: • a set of filial piety whose bottom forms an active space toward the inside of the set of rods, the movable space having an extending direction; _ a bolt from the top of the set of rods The inner portion of the sleeve is disposed in the sleeve, and the axis of the thread is parallel to the extending direction of the movable space; a screwing block is disposed in the movable space of the sleeve, and the bolt is Cooperating with each other, the screw block has a slope; a slider having a passage for the bolt to be inserted, the slider being disposed in the movable space of the sleeve, and located at the screw block and the sleeve Between the inner side walls; the slider has a slope; the sleeve is sleeved on the bicycle frame, the screw block and the slider are located in the bicycle frame, and the screw can be screwed when the bolt is screwed The block moves within the active space and pushes the slider. The cross section of the sleeve, the screw block, the slider and the bicycle frame is non-circular. The cross section of the sleeve, the screw block, the slider and the bicycle frame is in the shape of a diamond. Wherein the inner diameter of the passage of the slider is greater than the outer diameter of the bolt. Wherein the screw pick has an external thread and the external thread is located in the active space. 6 M322356 The set is made of carbon fiber. Into the staff [Implementation] Use the two diagrams to describe the technical slaves and effects used in this creation to achieve the purpose, and the following diagrams help explain, to facilitate the interpretation of the poems, the M is supplemented by the listed formula. Understand, but the technical means of this case are not limited.

The screwing block 13 is provided with an internal thread 131 and can be screwed with the external thread 121 of the screw king. The screwing block 13 has a slope. The slider 14 is disposed in the movable space U1 of the sleeve 且 and 1: between: 2 and the inner side wall 112 of the S rod 11 'the slider, both of which are about the axis β of the screw 2 And the through hole of the slider 14== the inner diameter of the 141 is larger than the tail 4 of the bolt 12, and has a slope 142, and the slope 142 7 M322356 of the slider 14 faces the slope 132 of the screw block 13, and The slope 142 of the slider 14 is in contact with the slope 132 of the screw block 13.

Referring to the third and fourth figures, the bicycle seat tamping sleeve 1 (as shown in the second figure) proposed by the present invention is inserted into the bicycle frame 20, and the bicycle frame 2 is inserted. The utility model comprises a seat rod 21 integrally formed of carbon fiber material, an upper front frame body 22, an upper rear frame body 23, a lower front frame body 24 and a lower rear frame body 25. The top of the seat post 21 is provided with a bicycle seat cushion for fixing The sleeve ίο is provided with a hollow joint portion 211. The joint portion 211 has a diamond-shaped cross section, and a step portion 212 is disposed outside the joint portion 211. As shown in the fifth to seventh figures, in order to cooperate with the above-mentioned seat post 21 in a diamond-shaped cross section, the set of the shank, the screw block 13, and the slider 14 of the present invention also have a diamond shape. The rod 11 is sleeved on the top of the seat frame 21 of the bicycle frame 2, and the bottom of the sleeve rod 1 can abut against the step portion 212. The screw block 13 and the slider η are located at the joint portion. 211; because the sleeve U, the screw block 13, the slider 14 and the seat rod 21 have a diamond-shaped cross section, when the bicycle seat cushion fixing sleeve 1 is sleeved on the joint portion 21, the sleeve 11 Between the joint section 211 and the screw block 13 and the slider 14 ^ the joint section 211 cannot be rotated by the bolt 12 as a center of the belt. As shown in the fifth figure, when the bolt 12 is initially screwed with the screw block 13 (when the slider 14 is not fully tightened), the slider 14 is loose due to the passage (4) of the slider 14. , the π ghost 14 series naturally falls on the inclined surface of the screw block 13 and the figure "when the outer part of the sleeve U is externally used by the tool 3 〇 ' can make the screw block 13 in the seat post 21 Parallel to this, the pin = heart direction B (that is, the extension direction A of the active space (1)) moves when the ^ 8 M322356

When the inclined surface 132 of the block 13 is in contact with the inclined surface 142 of the slider 14, the slider 14 can be pushed by the "squeezed block 13"; as shown in the seventh figure, when the slider 14 is continuously pushed by the screw block 13, The sliding force of the screw block 13 and the slider by the contact of the surface 132, 142 can cause the slider 14 to abut against the sleeve u and the inner side wall 112 of the seat post 21, so that the The joint portion 211 is deformed and expanded, so that the outer side wall of the joint portion 211 and the inner side wall of the joint portion 211 are closely abutted, so that the bicycle seat cushion fixing sleeve is firmly coupled to the top of the bicycle frame 20, and then the sleeve is u Place a bicycle seat cushion (not shown).
