Description

1276564 V. INSTRUCTIONS (1) [Technical field to which the invention pertains] The present invention relates to a seat-fixing device for a chain factory + an available-with-support beam, and more particularly to a type of riser connection. The surplus item is changed to the second solid part [and the body structure can be achieved with excellent practicability and cost effectiveness.胄 正 [Previous technique] Press, for example, the support structure; the sleeving groove 4 2 can be used for the seat cushion 50. The bundled seat 4 1 1 is clamped to the limit so that the seat cushion 50 can hunt the support rod 5 The locking joint method is matched to make it so that there is a support beam 7-position riser structure. The rear view extends to have a support block. The block 7 7 seat 6 1 is provided with a cushion pad 70 and a request Referring to the eighth figure, the seat cushion 'is connected to the support beam seat 61, whereas the toothed shape is fixed to the vertical position 4, and the bundle 5 1 accommodates the piece 4 3 lock 4 1 and the bundle. Tight 40 combined with tube 40 combined adjustment seat and riding demand ' is the first custom seat cushion answer 4 0 top forming a left and right tight seat 4 1 above a set of tightening piece 43 By being integrated, the support rod 5 piece 43 can be inserted into the groove 42 and integrated; however, the seat cushion 5 is integrated into one piece, but since it is fixed at an inclination angle of 5 〇, it is not lost.遂 There is a kind of second conventional knot 7 that can be assembled for the seat cushion and the second figure shown in the figure IX. The peripheral sides respectively provided above the standpipe 60, the head plane 62, and a through the two

Page 5,127,564 The invention discloses a shaft hole 63 of the toothed positioning surface 62, each of which has a toothed joint surface 65 corresponding to the toothed positioning surface 62, and a corresponding shaft hole 6 3 a through hole 6 6 , a clamping groove 6 7 corresponding to the clamping block 7 2 is disposed above the clamping member 6 4 ; the toothed engaging surface 65 of the two clamping members 64 and the tooth of the head holder 6 1 respectively The positioning surface 62 is engaged, so that the block 7 2 of the supporting beam 7 1 is engaged in the card slot 67, and then the plug 6 6 is used to extend and lock the connecting member 64 through hole 6 6 and the head seat. 6 1 shaft hole 63, so that the seat cushion 70 can be positioned by the clip of the clamping member 64 to be assembled on the riser 6 ,, and it can be loosened to release the clamping member 6 4 is to adjust the tilt angle of the seat cushion 70 to provide users with different riders. [Content] (Technical problem to be solved) However, the inventors have found that in the above-mentioned pole structure, it is necessary to change the top structure of the general riser in order to fit the seat cushion having the support beam at the bottom, and the design can be mutually joined. The head seat and the clamp member cause an increase in design cost, and the components thereof are complicated, and there is a need for improvement. (Technical means for solving the problem) • The present inventors have invented a kind of improvement based on the long-term research and integration of the seat cushion, which is mainly based on the connection of the general riser. Shuangqing: lock = the top of the block is a clip groove formed by the corresponding block of the seat cushion support beam, and the bottom of the block has a shaft hole, and the bottom of the clamp block is formed with a curved edge surface corresponding to the vertical code Z 2 Card slot; it is the opposite of the two missing blocks = seat

Page 6 1276564

The clamping groove and the card slot of a missing block are respectively clamped and clamped on the curved edge surface of the seat cushion supporting beam block and the head seat, and then the shaft hole of the two clamping block is penetrated by a plug body, and then locked. To securely engage the seat cushion support beam and the riser, the seat cushion and the riser can be integrally joined; the pillow can be released by releasing the plug body, adjusting the front and rear displacement of the seat cushion to an appropriate angle, and then locking it to provide use. The utility model has the functions of stable connection and convenient adjustment of the displacement and the inclination angle of the seat cushion, the components are simple, the assembly is convenient, and the utility model can be directly applied to the general riser structure, and the seat cushion can be extremely practical and cost-effective. Riser locking device. Compared with the prior art, it is indeed possible to achieve the integration of the clips by the present invention, and the structure is cost-effective. The top end of the clips are respectively clamped to the card and the two lock blocks are fixed. Displacement and adjustment to the user can facilitate the design of the tuning block to avoid duplicates such as the textbook and the component. The clamping groove and the bottom support are locked and can be designed, and the tilting angle of the whole seat pad can be appropriately tilted. The above description shows that the present invention has the following effects: 1. Simplify the component and reduce the cost: The block can be used to change the design of the top of the riser and the structure of the riser at the same time. It is indeed possible to simplify the assembly and lower the 2, and can be firmly engaged: due to the design of the card slot of the hair-end, the two clips can be Blocks. Beams and riser heads, and then use a plug to achieve the effect of a stable fit. 3, can be easily adjusted: Because the hair release the plug, adjust the seat to the front and rear, and then lock the plug, so as to provide the effect of displacement and tilt angle.

1276564 ------ V. Description of invention (4) [Comprehensive method] Please refer to the first to third and fourth A drawings. The present invention refers to a bicycle seat cushion riser locking device A, which constitutes The utility model comprises a riser 1 〇, a set of missing blocks 20 and a mat 30, wherein the riser 10 is sleeved inside the bicycle seat tube (not shown), and the riser 10 The top end of the support beam 3 1 has a support block 3 1 at the bottom end of the support beam 3 1 , and a block 3 2 is extended on the bottom side of the support beam 3 1 . 'The system is connected to the riser 1 透过 through a set of clamping blocks 20, and wherein: > the clamping block 20 forms a clamping block for supporting the seat cushion 3 2 clip groove 2 1 , a shaft hole 2 2 is arranged in the center of the block body and positioning protrusions 2 3 are protruded on both sides, and the bottom end of the clamp block 20 is formed corresponding to the curved edge surface 12 of the head seat. a curved arcuate card slot 2 4; which is such that the tongue and groove 2 1 is 2, respectively, and the two clamping edge arc surface 1 2 is located at the curved arc edge 5 respectively, and the two clamping jaws 2 〇 tube head seat 1 1 are respectively For example, the fourth A 塾 3 0 before and after the position 2 5 release, so that the two clips Clamping the clamping block 20, so that the clamping surface 1 2 is firmly clamped to the two clamping members, and the seat cushions ~C and five are moved and tilted to the seat cushion 3 2 0 relative to the bottom cushion of the seat cushion 3 2 0 parts of the hollow block 2 0 axis tightly engaged in the 3 0 and the vertical A ~ B diagram angle of the movement 0 can be set by the bottom, so that the two clips 0 support beam 3 1 2 2 4 respectively clamp the card positioning The protrusion 2 3 is located in the 1 3, and after the hole 2 2 is locked, the seat cushion 30 is supported, and the support beam 10 is joined to form a schematic diagram of the present invention, and the system supports the beam block 3 block 2 0 The clip side block 3 is fixed to the head base to accommodate a plug body to make the 31 and the stereo. Ming adjustment seat
