Description

Technical Field

[0001] This utility model relates to the field of bicycles, and in particular to a front fork limiting head cup. Background Technology

[0002] Currently, the limiting mechanism on the front of existing shared bicycles is limited to the fork limiter, which is limited by a welded truss. During market maintenance, transportation, or customer riding, the limiter is prone to deformation. The entire bicycle has a 60° limiter, which is easy to deform during customer riding, and the structure needs to be improved. Summary of the Invention

[0003] This invention addresses the aforementioned shortcomings of existing technologies by providing a front fork limiting headband cup that is easy to use, has an external waterproof ring that is not easily deformed during use, extends the service life of the entire device, restricts the front fork steerer tube from excessive rotation, and prevents cable entanglement and frame collision.

[0004] The objective of this utility model is achieved through the following technical solution: A front fork limiting cup includes an outer waterproof ring and an auxiliary connecting ring. The auxiliary connecting ring is connected to the inner side of the outer waterproof ring through a limiting bearing. The auxiliary connecting ring rotates within the outer waterproof ring. The outer waterproof ring has two reinforcing protrusions on its periphery, which are symmetrically arranged. The upper part of the outer waterproof ring has an adjustment groove, and the side wall of the adjustment groove has a positioning protrusion. The positioning protrusion has a No. 1 oil injection hole inside.

[0005] The bottom of the adjustment groove of this utility model has multiple positioning grooves, which are evenly distributed at the bottom of the adjustment groove, and a stop pad is connected to the inner side of the positioning groove.

[0006] The top of the stop washer of this utility model is connected to an auxiliary connecting ring, which slides on the stop washer. The bottom of the outer waterproof ring has a reinforcing ring, and the inner side of the reinforcing ring is connected to a fixing groove.

[0007] The bottom of the adjustment groove of this utility model has an auxiliary groove. The inner side of the auxiliary groove is connected to an auxiliary connecting ring through a limiting bearing. The auxiliary connecting ring rotates in the auxiliary groove. The outer side of the auxiliary connecting ring has two limiting protrusions, which are symmetrically arranged. The outer periphery of the auxiliary connecting ring has two No. 2 oil injection holes, which are symmetrically arranged and correspond to the No. 1 oil injection hole. The lower part of the No. 2 oil injection hole has an oil distribution hole, which is located directly above the limiting bearing. Beneficial effects

[0008] When in use, the fixing groove faces upward, and the limiting protrusion and positioning protrusion are not visible, which greatly improves the appearance of the whole vehicle. For forklift production, the forklift limiting mechanism does not need to be welded, and the forklift can be directly inserted into the auxiliary connecting ring. It is simple to operate and convenient to use.

[0009] This invention significantly improves the strength of the outer waterproof ring by strengthening the protrusion and reinforcing ring, making the outer waterproof ring less prone to deformation during use and extending the service life of the entire device.

[0010] This invention, through the cooperation of the limiting protrusion and the positioning protrusion, restricts the front fork steerer tube, limits its excessive rotation, and prevents cable entanglement and frame collision. Attached Figure Description

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments: Example 1: A front fork limiting head cup includes an outer waterproof ring 01 and an auxiliary connecting ring 02. The auxiliary connecting ring 02 is connected to the inner side of the outer waterproof ring 01 through a limiting bearing 15. The auxiliary connecting ring 02 rotates within the outer waterproof ring 01. The outer waterproof ring 01 has two reinforcing protrusions 09 on its outer periphery, which are symmetrically arranged. The upper part of the outer waterproof ring 01 has an adjusting groove 06, and the side wall of the adjusting groove 06 has a positioning protrusion 05. The positioning protrusion 05 has a first oil injection hole 07 inside. Under the action of the reinforcing protrusions 09 and the reinforcing ring 11, the strength of the outer waterproof ring 01 is greatly improved, making the outer waterproof ring 01 less prone to deformation during use and extending the service life of the entire device.

[0020] Example 2: The bottom of the adjustment groove 06 of this utility model has multiple positioning grooves 10, which are evenly distributed on the bottom of the adjustment groove 06. The inner side of the positioning groove 10 is connected to the stop pad 03.

[0021] Example 3: The top of the stop washer 03 of this utility model is connected to the auxiliary connecting ring 02, which slides on the stop washer 03. The bottom of the outer waterproof ring 01 has a reinforcing ring 12, and the inner side of the reinforcing ring 12 is connected to the fixing groove 11.

[0022] Example 4: The bottom of the adjusting groove 06 of this utility model has an auxiliary groove 13. An auxiliary connecting ring 02 is connected to the inner side of the auxiliary groove 13 via a limiting bearing 15. The auxiliary connecting ring 02 rotates within the auxiliary groove 13. The outer side of the auxiliary connecting ring 02 has two limiting protrusions 04, which are symmetrically arranged. The outer periphery of the auxiliary connecting ring 02 has two second-order oil injection holes 08, which are symmetrically arranged and correspond to the first-order oil injection hole 07. The lower part of the second-order oil injection hole 08 has an oil distribution hole 1. 4. The oil distribution hole 14 is located directly above the limit bearing 15. When in use, the fixing groove 11 faces upward, and the limit protrusion 04 and the positioning protrusion 05 are not visible. This greatly improves the appearance of the whole vehicle. For the production of the fork, the limit protrusion does not need to be welded. The fork can be directly inserted into the auxiliary connecting ring 02. The operation is simple and convenient. With the cooperation of the limit protrusion 04 and the positioning protrusion 05, the front fork steer tube is restricted, which limits the excessive rotation of the front fork steer tube and prevents the cable from getting tangled and the frame from colliding.

[0023] Example 5: Installation steps: When using this device, the fixing groove 11 should face upwards, and the limiting protrusion 04 and positioning protrusion 05 should not be visible. This greatly improves the appearance of the entire vehicle. For fork production, the fork limiting mechanism does not need to be welded; the fork can be directly inserted into the auxiliary connecting ring 02. The operation is simple and convenient. Under the action of the reinforcing protrusion 09 and the reinforcing ring 11, the strength of the outer waterproof ring 01 is greatly improved, making the outer waterproof ring 01 less prone to deformation during use and extending the service life of the entire device. With the cooperation of the limiting protrusion 04 and the positioning protrusion 05, the front fork steerer tube is restricted, limiting the excessive rotation of the front fork steerer tube and preventing cable entanglement and frame collision.

[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
