Description

Technical Field

[0001] This utility model relates to the field of bicycles, and in particular to an adjustable support for attaching extension accessories to a bicycle. Background Technology

[0002] Bicycles, as a means of leisure, sports, and commuting, have become an indispensable tool in people's lives. To facilitate cyclists, extended racks are installed on bicycles to allow riders to hang loads, such as water bottles, action cameras, and backpacks. These extended racks typically use a bracket that locks onto the bicycle's handlebars / steel tubes as a fixing point. The load is then attached to the bicycle via appropriate extension accessories that plug into / clip onto the bracket, thereby reducing the rider's burden or making it easier for them to handle the load.

[0003] In addition to the structure for inserting extension accessories, the existing bracket also includes a retaining hook with an angled surface. When the extension accessory is inserted into the bracket, the hook will keep the extension accessory in the inserted state to prevent it from coming off. When it is necessary to remove the extension accessory, it can be removed from the bracket by controlling the extension accessory to release its contact with the hook.

[0004] The existing bracket uses a fixed structure for the hooks. While this can improve the stability of the extension accessories, the extension accessories produced by different manufacturers are not standardized. This dimensional error will cause the hooks to be unable to secure the extension accessories stably when they are plugged into the bracket, making the extension accessories loose. This may lead to the load falling off or the extension accessories becoming unusable during riding due to bumps or shaking. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] like Figure 1 As shown, the present invention discloses an adjustable support for bicycles, including a base 1 fixed to the bicycle. The specific fixing position can be selected according to the rider's needs, such as being installed on the handlebars or on the frame. In addition, the specific number of supports can also be determined as needed.

[0022] An annular mounting plate 2 and a retractable hook 3 are installed on the base 1. The annular mounting plate 2 serves as the insertion base for the extension accessories of the load. The hook 3 can adjust the contact distance with the extension accessories when they are inserted into the annular mounting plate 2 using its own elasticity. The specific elastic structure can be a spring or leaf spring, which can allow the hook 3 to extend and retract when the load is inserted. The hook 3 also provides a tight and stable fixing point for the inserted extension accessories, thereby preventing the load from falling off due to the loosening of the extension accessories.

[0023] For ease of installation, in one embodiment of this invention, a U-shaped groove 11 extending to one side is provided on the base. A hook 3 is fixed within the U-shaped groove 11, and an annular hanging plate 2 is installed at the opening of the U-shaped groove 11 via the hook 3. The U-shaped groove 11 provides installation space for other components and also allows adjustment of the extended length of the base 1, providing better operating space for the installation of extension accessories. Although it is stated here that the annular hanging plate 2 is fixed to the U-shaped groove 11 via the hook 3, in other embodiments, the annular hanging plate 2 can also be directly fixed to the open end of the U-shaped groove 11, as long as the hook 3 can effectively fix the annular hanging plate 2.

[0024] like Figure 2 , 3 As shown in Figure 4, in one embodiment of this utility model, the specific hook 3 includes a hook seat 32 with a channel 34, an adjusting bolt 31 installed in the hook seat 32, a lever 4 that contacts the hook seat 32 and has a threaded hole 41, one end of the adjusting bolt 31 is a fixed end 311 and the other end is a screw end 312, and a locking platform with an inclined surface is provided on the fixed end 311.

[0025] During installation, the screw end 312 of the adjusting bolt 31 is inserted into the channel 34 of the hook seat 32 and then screwed into the threaded hole 41 on the lever 4. A spring 5 is fitted on the rod body of the adjusting screw 31 located in the hook seat 32. In the non-use state, the fixed end 311 extends out of the channel 34 of the hook seat 32 under the action of the spring 5 (protruding relative to the insertion plane of the annular hanging plate 2).

[0026] like Figure 5 , 6As shown, the hook seat 32 can be fixed in the U-shaped groove 11 by bolts. The lever 4 is movably installed relative to the hook seat 32. When the lever 4 is moved axially, it drives the screwed adjusting bolt 31 to move relative to the hook seat 32, so that the fixed end 311 of the adjusting bolt 31 moves inward / outward to the hook seat 32, thereby adjusting the distance between the adjusting bolt 31 and the extension accessory. When the fixed end 311 of the adjusting bolt 31 enters the channel 34, the extension accessory can be inserted into the annular hanging plate 2. After insertion, the lever 4 is released to allow the adjusting bolt 31 to return to its original position using the elastic force of the spring 5. At this time, the fixed end 311 of the adjusting bolt 31 can automatically lock the extension accessory in the current insertion position. During this process, the adjusting bolt 31 can automatically adjust the extension length according to the gap between the extension accessory and the annular hanging plate 2, thereby preventing the extension accessory from loosening. In addition, the length of the adjusting bolt 31 screwed into the lever 4 through the screw end 312 can be adjusted to adjust the distance of the fixed end 311 protruding relative to the through hole 34, so that the fixed end 311 can better adapt to the insertion of different extension accessories.

[0027] This invention improves the compatibility and stability of extension accessories from different manufacturers. Users can also adjust the tightness of the hook's contact with the extension accessory by adjusting the extension range of the hook. The ring-shaped mounting plate adopts a two-sided wraparound sliding groove design, which not only accommodates existing commercially available accessories but also provides installation possibilities for future expansion of accessories. The entire bracket adopts a modular design, which can adapt to different shapes or replace different resistance components to meet the needs of different groups.

[0028] like Figure 7 As shown, in order to facilitate the insertion of extension accessories, in one embodiment of this utility model, two annular hanging plates 2 are provided. A recessed slot 21 is provided on the outer peripheral surface of the annular hanging plate 2, and a protruding locking strip 33 is provided on the two opposite outer surfaces of the locking hook seat 32. The two annular hanging plates 2 are respectively inserted into the locking strips 33 on both sides of the locking hook seat 32 through the slot 21.

[0029] The annular mounting plate 2 can be directly fixed to the locking strip 33 via the slot 21, or it can be fixed to the hook seat 32 via the fixing bolt 23 passing through the slot 21 of the annular mounting plate 2. After using the fixing method of the fixing bolt 23, the relative height (vertical position) of the annular mounting plate 2 relative to the hook seat 32 can be adjusted before fixing the annular mounting plate in the current position. This method can more conveniently adjust the fixing point of the hook 3 relative to the extension accessory, further improving the effect.

[0030] Furthermore, to facilitate the insertion of extension accessories, the interior of the annular mounting plate 2 is designed as a hollow structure to form a sliding mounting groove 22.

[0031] In one embodiment of this utility model, to facilitate the movement of the lever 4, the side of the lever 4 that contacts the U-shaped groove 11 of the base 1 is set as a plane. After the lever 4 is inserted into the U-shaped groove 11, the planes on both sides fit against the inner side of the U-shaped groove 11, so that the lever 4 can only move along the axial direction of the U-shaped groove 11 and cannot rotate radially. In addition, this structure can also prevent the hook seat 32 from detaching from the U-shaped groove 11 due to shaking.

[0032] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
