Description

Technical Field

[0001] This utility model relates to the field of handle tube connection structure technology, and in particular to a locking structure for a bent handle tube. Background Technology

[0002] In the existing scooter handlebar locking structures on the market, the handlebar is generally connected to the frame through a connecting sleeve. The handlebar is divided into straight handlebar and curved handlebar. The straight handlebar usually has an opening on the connecting sleeve for single-sided tightening, resulting in high connection strength. The curved handlebar, on the other hand, requires the connecting sleeve to be split in two, with one side of the connecting sleeve acting as a pressure cap. The curved handlebar is locked to the other side of the connecting sleeve through the fastening structure on the upper and lower sides of the pressure cap. This structure is complex, has low connection strength, is not aesthetically pleasing, and is not cheap. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this utility model provides a bending handle tube locking structure that is simple in structure, has high connection strength, is inexpensive, and aesthetically pleasing.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] This utility model discloses a locking structure for a curved handle tube, comprising a connecting sleeve, a filler, and a connecting seat. The connecting sleeve is arranged horizontally and positioned in front of the connecting seat. The connecting sleeve has a shaped hole through which the curved handle tube passes. The filler is used to fill the gap between the shaped hole and the curved handle tube. The lower side of the connecting sleeve has a transversely oriented opening groove that communicates with the shaped hole. A locking component is provided at the opening groove to control the opening and closing of the opening groove, thereby controlling the locking / unlocking of the connecting sleeve, the filler, and the curved handle tube.

[0006] In this solution, the connector is used to connect with the frame. The handlebar tube is passed through the irregular hole, and then the filler is inserted into the irregular hole to fill the gap between the irregular hole and the handlebar tube. Then, the locking component controls the closure of the opening slot. As the opening of the opening slot becomes smaller, the size of the irregular hole decreases, locking the connector, filler and handlebar tube. At this time, the handlebar tube is locked and fixed.

[0007] Preferably, the front side of the bend handle tube is provided with a guide groove that runs in the same direction as the bend handle tube, and the rear side of the filler is provided with a limiting protrusion that matches the guide groove and can slide along the guide groove.

[0008] After the limiting protrusion slides into the guide groove, it facilitates the movement of the filler along the curved handle tube into the irregular hole.

[0009] Preferably, the irregular hole includes an arc-shaped hole, a square hole, and a round hole that are connected sequentially from front to back.

[0010] Preferably, the front side of the filler is provided with an arc-shaped surface that matches the arc-shaped hole.

[0011] As the irregular hole becomes smaller, the arc-shaped surface on the front side of the filler gradually comes into close contact with the arc-shaped hole in the irregular hole.

[0012] Preferably, the locking assembly includes locking screws arranged symmetrically on the left and right sides. A screw through hole is provided on the front side of the opening groove corresponding to the position of the locking screw, and a threaded hole is provided on the rear side of the opening groove corresponding to the position of the screw through hole. The threaded part of the locking screw passes through the corresponding screw through hole and the opening groove in sequence and is threadedly connected to the corresponding threaded hole.

[0013] Two locking screws are screwed into the corresponding threaded holes through the corresponding screw holes. As the two locking screws are tightened, the opening of the slot becomes smaller, which makes the size of the irregular hole smaller. As the irregular hole becomes smaller, the connecting sleeve, filler and bent handle tube are locked and fixed.

[0014] The beneficial effects of this utility model are: the curved handle tube is passed through the irregular hole, and then the filler is inserted into the irregular hole so that the filler fills the gap between the irregular hole and the curved handle tube. Then the connecting sleeve, the filler and the curved handle tube are locked and fixed by the locking assembly; after the limiting protrusion slides into the guide groove, it is convenient for the filler to move along the curved handle tube into the irregular hole.

[0021] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0022] Example: A locking structure for a bent handle tube in this example, such as... Figures 1 to 5 As shown, the device includes a connecting sleeve 1, a filler 2, and a connecting seat 3. The connecting sleeve 1 is arranged horizontally and is located in front of the connecting seat 3. The connecting sleeve 1 has a shaped hole 4 for the curved handle tube 5 to pass through. The filler 2 is used to fill the gap between the shaped hole 4 and the curved handle tube 5. The lower side of the connecting sleeve 1 has an opening groove 11 arranged horizontally, which communicates with the shaped hole 4. A locking component is provided at the opening groove 11. The locking component is used to control the opening and closing of the opening groove 11 (i.e., control the opening degree of the opening groove 11), thereby controlling the locking / unlocking of the connecting sleeve 1, the filler 2, and the curved handle tube 5.

[0023] The front side of the curved handle tube 5 is provided with a guide groove 51 that is consistent with the direction of the curved handle tube, and the rear side of the filler 2 is provided with a limiting protrusion 21. The limiting protrusion 21 matches the guide groove 51 and can slide along the guide groove 51.

[0024] The irregular hole 4 includes an arc-shaped hole, a square hole, and a round hole that are connected sequentially from front to back.

[0025] The front side of the filler 2 is provided with an arc-shaped surface 22 that matches the arc-shaped hole.

[0026] The locking assembly includes locking screws 6 arranged symmetrically on the left and right. A screw through hole 111 is provided on the front side of the opening groove 11 corresponding to the position of the locking screw. A threaded hole 112 is provided on the rear side of the opening groove 11 corresponding to the position of the screw through hole 111. The threaded part of the locking screw 6 passes through the corresponding screw through hole 111 and the opening groove 11 in sequence and is threadedly connected to the corresponding threaded hole 112.

[0027] In this design, the connector is used to connect to the frame. When installing the handlebar tube, it is inserted into the shaped hole. During insertion, the bend in the handlebar tube passes through the shaped hole... Figure 3 As shown, after the curved handle tube is inserted, the limiting protrusion on the rear side of the filler is slid into the guide groove, so that the filler moves along the curved handle tube into the irregular hole. The filler fills the gap between the irregular hole and the curved handle tube. The two locking screws are screwed into the corresponding threaded holes through the corresponding screw holes. As the two locking screws are tightened, the opening of the slot becomes smaller, making the size of the irregular hole smaller. As the irregular hole becomes smaller, the connecting sleeve locks the filler and the curved handle tube. The arc-shaped surface on the front side of the filler gradually comes into close contact with the arc-shaped hole in the irregular hole. At this time, the curved handle tube is locked and fixed.
