Description

Bicycle seat cushion pressing device

The present invention relates to a bicycle seat cushion pressing device, and more particularly to a bicycle seat cushion pressing device which is convenient for fixing and replacing the bushing and saving assembly time.

According to the conventional bicycle seat cushion, the height and position of the bicycle can be adjusted, and a bottom tube is arranged at the bottom of the seat to support the seat cushion. The bottom end of the seat cushion tube extends into a socket of the frame. After that, use a pressing device to position it. The pressing device comprises a bushing, a pressing member and a pushing member. The bushing is fixed in the socket by gluing, and the pressing member is embedded in the bushing, and is pushed by the pushing member to firmly position the wall of the cushion pipe. However, the conventional bushing and the pipe base are glued and fixed, so that the bushing cannot be replaced and repaired after being damaged, and when the gluing is fixed, the bushing needs to be further used to pass the bushing and the pipe by the jig and the oven. Gluing, construction is very time-consuming and labor-intensive, obviously needs to be improved.

In response to the above shortcomings, the creator has intensively conceived R&D creations, and after a long period of hard work, he has created this creation.

Therefore, the purpose of this creation is to provide a bicycle seat cushion pressing device that facilitates assembly, replacement, and assembly of labor.

In order to achieve the above object, the bicycle seat cushion pressing device of the present invention comprises a bushing, a pressing member, a coupling device and a pushing member. Wherein the bushing is disposed in a socket The bushing has a hollow end and a fixed end, and the hollow end has a through hole in the middle, the through hole can pass through a gasket, the fixed end has a fixing block, and the fixing block has a a receiving section, the receiving section has an opening facing the opening end, the opening is in communication with the opening, the inner wall of the receiving section has an inner screw hole extending all the way to the outside of the socket; the pressing part passes through the The opening is received in the receiving portion, the pressing member has a first end and a second end, the first end faces the cushion tube via the opening, and the second end faces the inner screw hole; the coupling device The sleeve is locked by the sleeve after passing through the socket; the pushing member extends from the outside of the socket into the inner screw hole, and the end portion is used for pushing the second end of the pressing member The first end of the pressing member is inserted into the opening of the bushing to press the wall of the seat tube. The bushing is fixed in the socket by the bonding device, so the bushing can be easily assembled, replaced, and save assembly time.

The present invention has been described in detail with reference to the accompanying drawings.

Please also refer to the first to third figures, the bicycle seat cushion pressing device 1 of the present embodiment includes:

A bushing 10, as shown in the third and fourth figures, is disposed in an accommodating section 20 in the base 2 of the frame, and the accommodating section 20 extends all the way to the inside of the upper tube 3 of the bicycle. The space 20 is provided with a positioning step 200 at the end of the stem 2. The bushing 10 has a hollow end 100 and a fixed end 101. The bottom end of the hollow end 100 is fastened on the positioning step 200 (as shown in FIG. 5 and FIG. 6). The hollow end 100 has a port 102 in the middle. The through hole 102 can pass through a gasket 4; the fixed end 101 has a fixing block 103, and the fixing block 103 has a receiving portion 104 therein, and the receiving portion 104 faces the cushion tube 4 The end portion has an opening 105, and the opening 105 communicates with the opening 102. The inner end of the receiving portion 104 has an inner screw hole 106 that leads to the outside of the socket 2.

A pressing member 11, as shown in the third and fourth figures, is similar to a triangular block and is accommodated in the receiving section 104 via the opening 105. The pressing member 11 has a first end 110 and a second end 111. The second end 111 and the first end 110 have an angle A of less than 90 degrees. The first end 110 faces the port 102 (ie, facing the cushion tube 4) via the opening 105; the second end 111 faces the inner screw hole 106.

a coupling device 5 is disposed on the bottom surface of the socket 2, and can be locked through the socket 2 and the fixing block 103 of the bushing 10; and a pushing member 6 is a bolt extending from the socket 2 Inside the inner screw hole 106. The bottom end of the pushing member 6 is provided with a hexagon socket groove 60, and an end of a tool (such as a hex wrench) is inserted into the hexagon socket groove 60 to adjust the pushing or not pushing of the end of the pushing member 6. The second end 111 of the pressing member 11 is.

Referring to the second and third figures, the top port of the socket 2 can be sleeved with a hollow inner gasket 7 and an outer gasket 8 to protect and beautify the top port of the socket 2.

Referring to the third and fourth figures, the bonding device 5 is disposed at a bottom end of the stem 2 and located adjacent to the lower tube 3, and includes a pressing plate 51 and at least one screw 53. The pressure plate 51 is disposed at one end of the bottom of the socket 2 for the screw member 53 to pass through, and the screw member 53 passes through the pressure plate 51. Thereafter, the end portion extends into the stem 2 to be screwed to the fixing block 103 of the bushing 10, and the bushing 10 and the stem 2 are integrally fixed.

Referring to the fifth and sixth figures, when the pushing member 6 does not push the pressing member 11 to press the seat tube 4, as shown in FIG. 5; the pushing member 6 pushes the pressing member 11 to force When the seat tube 4 is tightened, it is as shown in the sixth figure. When the bushing 10 is to be replaced, the screw 53 of the binding device 5 is retracted from the fixing block 103, and the bushing 10 can be taken out of the receiving section 20 for replacement or repair, and the bushing 10 can be fixed or replaced. Very convenient and labor-saving.

In summary, the present invention can achieve the intended function and purpose, and the detailed description can be implemented by those skilled in the art, and the above embodiments are only used to illustrate the creation, all equivalent structures.
