Carrying frame with ball-type control grip structure

Abstract

A ball-clamping control handle structure for a vehicle carrier includes a fixed base, a control handle, and a control unit. The fixed base houses a ball-clamping assembly for holding a trailer ball and has a shaft connection at its upper end. The control handle is shaft-connected to the shaft connection of the fixed base, controlling the clamping or releasing of the ball-clamping assembly. The control unit is located at the front end of the main member and has a hollow structure and an inclined surface. A window on the inclined surface displays the locking status of the hook. The hook is driven by a locking cylinder, and its engaging end can be fixed or detached from the positioning part of the fixed base. When the hook is locked, the display surface is visible in the window, confirming the fixed status. When the locking cylinder is rotated to unlock, the engaging end of the hook disengages from the positioning part, the display surface is no longer visible in the window, and a torsion spring causes the hook to rebound, facilitating subsequent operations. Through the window design and spring rebound mechanism, the safety and convenience of the fixing mechanism are improved, making it suitable for the quick installation and removal of trailer balls.

Description

Technical Field

[0001] This invention relates to bicycle frame accessories, specifically a bicycle frame with a ball-type control grip structure, which is particularly used to improve the grip locking method of the bicycle frame, thereby enhancing ease of use and safety. Prior Technology

[0002] Note that most existing bike carriers use a manual locking mechanism. Due to asynchronous operation, the handles used for fixing can easily become loose, which may cause the bike carrier to detach from the trailer ball and fall off.

[0003] How to solve the above problems is a topic that relevant businesses are actively addressing. Summary of the Invention

[0004] This invention provides a bicycle frame with a ball-clamping control grip structure. The main purpose is to provide a structure design for automatic hook engagement, and the presence or absence of engagement can be displayed through a window on the grip, allowing the user to quickly determine whether the device is securely fastened.

[0005] This invention provides a ball-clamping control grip structure for a bicycle frame. The secondary purpose is to connect the hook and the torsion spring coaxially. When the lock cylinder rotates, the hook moves synchronously, and when the lock cylinder is released, the torsion spring automatically resets, forming an automatic locking function.

[0006] Therefore, the structure of the present invention includes:

[0007] A fixed base, wherein a ball clamping assembly is provided inside the fixed base to clamp and fix a trailer ball, and the upper end of the fixed base is provided with a triangular shaft connecting part;

[0008] A control handle, which is pivotally connected to the shaft connection portion of the fixed base, is used to control the clamping ball assembly to clamp or release the trailer ball; characterized in that:

[0009] The control grip has a side bar on each side of a main rod, and the front end of each side bar has a pivot part that is triangular in shape and corresponds to the shaft connection part.

[0010] A control unit is attached to the front end of the main rod. This control unit is a hollow structural component with an inclined surface and a through-window. A mounting hole is located at the lower end of the inclined surface. A hook and a torsion spring are mounted on the front end of the main rod. A locking cylinder is provided in the mounting hole. The hook and torsion spring are coaxially connected, and the hook rotates under the influence of the locking cylinder. Furthermore, an abutment wall at the front end of the inclined surface provides abutment and positioning for the torsion spring. A latching end is located at the lower end of the hook, which is fixed or detached from a positioning part of the fixing base. The upper end of the hook is bent to form a display surface.

[0011] When the mounting bracket locks the trailer ball in position, the latching end of the hook is embedded in the positioning part. By rotating the locking cylinder, the hook position is locked, and the display surface can be directly seen in the window, confirming that the hook position is locked. To unlock, rotate the locking cylinder so that the latching end of the hook separates from the positioning part. In this state, the display surface cannot be seen in the window. When the locking cylinder is released, the hook rebounds due to the elasticity of the torsion spring, making it ready for subsequent fixing.

[0012] In an embodiment of the present invention, the display surface of the hook is further coated with color.

[0013] In an embodiment of the present invention, the lock cylinder is provided with a semi-circular positioning surface, and the aforementioned hook is rotated by the positioning surface.

[0014] In an embodiment of the present invention, a sleeve is provided at the rear end of the control unit, the sleeve being used to cover the main rod.

[0015] In an embodiment of the present invention, a triangular gasket is provided between the shaft connection portion of the fixing seat and the pivot portions thereof.

[0016] In an embodiment of the present invention, the mounting base is provided with a pivotable cover.

[0017] Based on the above description, the features and effects of the present invention are briefly summarized as follows:

[0018] 1. The lock cylinder directly drives the hook and torsion spring to rotate synchronously, making it convenient to use.

[0019] 2. The hook is automatically reset by using a torsion spring, thus achieving an automatic locking function.

[0020] 3. Use the viewing window to directly observe whether the hook is engaged with the positioning part, so that the user can know whether the control grip is pressed and fixed to the fixing seat. Simple Explanation of the Diagram

[0022] As shown in Figure 1 and Figure 3, the present invention comprises a frame-mounted ball-type control grip structure, consisting of a fixed base 10 and a control grip 20.

[0023] As shown in Figures 1, 3, 5 and 6, a ball clamping assembly 11 is provided inside the fixing base 10 to clamp and fix a trailer ball 30. The upper end of the fixing base 10 is provided with a triangular shaft connecting part 12. The ball clamping assembly 11 can clamp or release the trailer ball 30 by being pressed or released by the control handle 20.

[0024] As shown in Figures 1 to 5, the control handle 20 is axially connected to the shaft connection part 12 of the fixed base 10, and the control handle 20 controls the ball clamping assembly 11 to clamp or release the trailer ball 30.

[0025] Please refer to Figures 1 through 5. The control grip 20 has a side rod 22 on each side of a main rod 21. The front end of the side rod 22 is provided with a pivot part 23 that is triangular and corresponds to the shaft connection part 12. In addition, as shown in Figure 3, a triangular gasket 40 is provided between the shaft connection part 12 and the pivot part 23 of the fixed seat 10.

[0026] Please refer to Figures 1 through 5. A control unit 50 is located at the front end of the control grip 20. This control unit 50 is attached to the front end of the main rod 21. The control unit 50 is a hollow structural component and has an inclined surface 51 with a through window 52. A mounting hole 53 is located at the lower end of the inclined surface 51. A hook 54 and a torsion spring 55 are located inside the front end of the main rod 21. The mounting hole 53 is for a lock cylinder 56. The aforementioned hook 54 and torsion spring 55 are coaxially connected, and the hook 54 is driven by the lock core 56. In addition, the front end of the inclined surface 51 is provided with an abutting wall 57 to provide the torsion spring 55 for abutting and positioning. The lower end of the hook 54 is provided with a fastening end 541, which is fixed or separated from a positioning part 13 of the fixing base 10. In addition, the upper end of the hook 54 is bent to form a display surface 542, and color can be applied to the display surface 542 for identification.

[0027] In addition, the rear end of the control unit 50 is provided with a sleeve 58, which covers and hides the main rod 21.

[0028] As shown in Figure 5, when the mounting base 10 locks the trailer ball 30 in position, the latching end 541 of the hook 54 is embedded in the positioning part 13, and the lock core 56 is rotated to lock the position of the hook 54. The window 52 can directly see the display surface 542, thus confirming that the position of the hook 54 has been locked.

[0029] As shown in Figure 6, when the lock is to be released, the lock cylinder 56 is rotated so that the latching end 541 of the hook 54 is separated from the positioning part 13. In this state, the display surface 542 cannot be seen in the window 52. When the lock cylinder 56 is released, the hook 54 is elastically driven to rebound by the torsion spring 55 so that it can be used for subsequent fixing.

[0030] Furthermore, as shown in the third figure, the aforementioned lock cylinder 56 is provided with a semi-circular positioning surface 561. The aforementioned hook 54 is driven to rotate by the positioning surface 561, so that it can be rotated synchronously with the lock cylinder 56.

[0031] Accordingly, as shown in Figure 7, pushing the control handle 20 upward will cause the ball clamping assembly 11 to move downward, so that the ball clamping assembly 11 will not clamp the trailer ball 30, allowing the fixing seat 10 to separate from the trailer ball 30.

[0032] To hold the trailer ball 30 in place, press down the control handle 20 so that the locking end 541 engages with the positioning part 13 to achieve an automatic locking effect.
