Description

Technical Field

[0001] This utility model relates to the field of quick-release lever locks for bicycle tube clamps, and in particular to a double-locking structure for tube clamps. Background Technology

[0002] The existing technology for bicycle tube clamps and quick-release locks does not have a protective anti-disengagement mechanism after tightening. Over time, they are prone to loosening and causing safety hazards, especially quick-release locks on parts such as the head tube, crossbar, and seatpost. These pose a significant safety risk when used for extended periods of riding or when ordinary users do not carefully inspect the lock joints. Utility Model Content

[0003] To address the shortcomings mentioned above, this utility model provides a double-locking structure for pipe clamps.

[0004] To achieve the above objectives, this utility model proposes a double-locking structure for a pipe clamp, comprising a lock, a pipe clamp, a pin, and a spring; the lock has a locking hook at one end, a shaft hole in the middle, and a locking handle at the other end, with a spring hole on the side of the locking handle; the pipe clamp is composed of a clamping ring and a handle; a protruding locking plate is provided on one side surface of the clamping ring; a groove is provided at one end of the handle, with a spring hole at the bottom of the groove and pin holes on both sides of the groove; the locking handle is located within the groove, and the pin passes through the shaft hole and the pin hole; the two ends of the spring are respectively connected to the spring hole and the spring hole; the clamping ring and the handle are connected to each other via a connecting assembly.

[0005] As a preferred embodiment of this utility model, the connecting component includes a connecting cap, a connecting rod, a connecting washer, and a connecting pin. The connecting pin is disposed in the through hole at the other end of the handle. The connecting cap is screwed to one end of the connecting rod. The other end of the connecting rod passes through the through hole and the connecting washer on the other side of the clamp ring in sequence and is screwed to the connecting pin, thus connecting the other end of the handle to the surface of the clamp ring. The handle rotates around the end of the connecting component as a fulcrum, thereby achieving the locking function of pressing the clamp ring to tighten or releasing the clamp ring.

[0006] In a preferred embodiment of this utility model, when the pipe clamp is in the locked state, the handle is attached to the surface of the clamping ring. At this time, the locking hook at one end of the locking buckle hooks onto the locking platform protruding from one side of the clamping ring, which acts as a safety buckle to prevent the handle from coming off.

[0007] As a preferred embodiment of this utility model, the latch is centered on a pin. By pressing the lock handle into the groove at the end of the handle, the spring can be contracted, and the lock hook can rotate along the pin.

[0008] The beneficial effects of this utility model are as follows: When the handle on the pipe clamp is closed, the handle presses against the clamping ring, causing the pipe clamp to exert a clamping force on the pipe fitting. Simultaneously, the locking hook on the latch slides over the protruding locking platform surface of the clamping ring and engages with the side of the locking platform, thus acting as a safety catch to prevent the handle from coming loose. This significantly reduces the safety hazards caused by loosening or prying open of the pipe clamp handle due to human or other non-human factors. Furthermore, it is easy to operate, aesthetically pleasing when closed, highly safe, eliminates complex operating procedures and potential for misinterpretation, and has a more robust structure.

[0009] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

Detailed Implementation

[0016] See Figures 1-5 This utility model provides the following technical solution:

[0017] A double-locking structure for a pipe clamp includes a lock 1, a pipe clamp 2, a pin 3, and a spring 4. The lock 1 has a locking hook 11 at one end, a shaft hole 12 in the middle, and a locking handle 13 at the other end. The locking handle 13 has a spring hole 14 on its side. The pipe clamp 2 is composed of a clamping ring 21 and a handle 22. The clamping ring 21 has a protruding locking platform 211 on one side surface. The handle 22 has a groove 221 at one end, a spring hole 222 at the bottom of the groove 221, and pin holes 223 on both sides of the groove 221. The locking handle 13 is located in the groove 221, and the pin 3 passes through the shaft hole 12 and the pin hole 223. The two ends of the spring 4 are respectively connected to the spring hole 14 and the spring hole 222. The clamping ring 21 and the handle 22 are connected to each other by a connecting assembly.

[0018] The connecting assembly includes a connecting cap 23, a connecting rod 24, a connecting washer 25, and a connecting pin 26. The connecting pin 26 is located in the through hole at the other end of the handle 22. The connecting cap 23 is screwed onto one end of the connecting rod 24. The other end of the connecting rod 24 passes through the through hole on the other side of the clamping ring 21 and the connecting washer 25 in sequence and is screwed onto the connecting pin 26, connecting the other end of the handle 22 to the surface of the clamping ring 21. The handle 22 rotates around the end of the connecting member 23 as a fulcrum, thereby achieving the locking function of pressing the clamping ring to tighten or releasing the clamping ring.

[0019] When the pipe clamp 2 is in the locked state, the handle 22 is attached to the surface of the clamp ring 21. At this time, the locking hook 11 at one end of the locking buckle 1 hooks the locking platform 211 protruding from one side of the clamp ring 21, which acts as a safety buckle to prevent the handle 22 from coming off.

[0020] With the pin 3 as the axis, the lock 1 can cause the spring 4 to contract by pressing the lock handle 13 into the groove 221 at the end of the handle 22, while the lock hook 11 rotates along the pin 3.

[0021] The working process of this utility model:

[0022] When the new pipe clamp with double locking structure designed in this scheme is in operation, after the handle 22 on the pipe clamp 2 is closed, the handle 22 presses the clamping ring 21 to tighten it, so that the pipe clamp 2 will generate a clamping force on the pipe fitting. At the same time, the locking buckle 1 rotates along the pin 3, so that the locking hook 11 at the end slides over the surface of the locking platform 211 protruding from the clamping ring 21 and fits against the side of the locking platform 211. The locking hook 11 hooks the locking platform 211, thereby playing the role of a safety buckle and preventing the handle 22 from coming off.

[0023] When opening, press the lock handle 13 into the slot 221 at the end of the handle 22 to retract the spring 4. At the same time, the lock hook 11 rotates along the pin 3 to disengage from the side of the lock platform 211. Continue to press the lock 13 and the surfaces on both sides of the slot 221 at the end of the handle 22 until the handle 22 on the pipe clamp 2 is opened in the opposite direction. The handle 22 releases the pressure on the clamping ring 21, causing the pipe clamp 2 to release the clamping force on the pipe fitting.

[0024] The double-locking structure of pipe clamp 2 has better overall practicality, which helps to solve the safety hazards caused by the loosening or prying open of the handle 22 of pipe clamp 2 due to human factors or other non-human factors; moreover, it is easy to operate, has an aesthetically pleasing appearance after closure, and is highly safe. It eliminates the need for complicated operating procedures and misleading information, has a more robust structure, higher joint load-bearing strength, and better overall practicality of the device.

[0025] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
