Description

Technical Field

[0001] This utility model relates to the field of mechanical joint structures, and in particular to a handle angle adjustment structure. Background Technology

[0002] There are numerous joint structures in folding strollers and other similar products, the most common being the stroller handle. The handle joints typically need to be designed to be angle-adjustable to accommodate different users. A relevant solution is the stroller locking and unlocking device disclosed in patent document CN213948550U. While this solution can lock the angle, it has some problems in use. First, the structure is relatively complex, placing a burden on cost and performance stability. Second, the locking strength is relatively weak, making slippage prone to occur. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a handle angle adjustment structure, which uses a driving slider to lock and unlock the relative angle between the handle body and the base. It is simple to combine, low in cost, has better stability and firmness, and the control process is more efficient and convenient.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a handle angle adjustment structure, including a handle body and a base;

[0005] The handle body has a handle turntable at its end, the handle turntable has a handle cavity groove on its surface, the side wall of the handle cavity groove has a limit pin hole, the limit pin hole has a spring limit pin pointing into the handle cavity groove, the tail end of the spring limit pin is connected to one end of the drive cable, and the other end of the drive cable extends to the handle body.

[0006] The base is provided with a base turntable, and the turntable is provided with a limiting boss corresponding to the handle cavity groove; the base turntable is rotatably engaged with the handle cavity groove, the limiting boss is rotatably engaged with the handle cavity groove, and the side wall of the limiting boss is provided with a plurality of limiting slots that are adapted to the front end of the spring limiting pin.

[0007] This design allows the handle body to rotate relative to the base via a handle disc and a base disc. Under normal circumstances, the handle body can rotate relative to the base to change its angle. Since the front end of the spring-loaded limiting pin matches a limiting slot on the side wall of the limiting boss, when the front end of the spring-loaded limiting pin aligns with the limiting slot, it engages, locking the angle of the handle disc relative to the base disc. Changing the angle between the handle body and the base, and allowing the front end of the spring-loaded limiting pin to match different limiting slots, allows for locking at different angles relative to the base. To unlock, pinch the unlock switch and pull the drive cable backward. Releasing the unlock switch releases the drive cable, re-locking the relative positions of the handle disc and the base disc.

[0008] Preferably, the handle cavity groove has an inner shaft at its center, which rotates in conjunction with the base turntable. This allows the handle turntable and the base turntable to rotate more stably relative to each other.

[0009] Preferably, the side wall of the spring limiting pin is provided with a limiting strip hole along the axial direction, and a travel pin passes through the limiting strip hole, with the end of the travel pin fixed to the limiting pin hole. This facilitates limiting the forward and backward sliding stroke of the spring limiting pin.

[0010] Preferably, the handle body is provided with a squeezing part, the squeezing part is longitudinally slidably engaged with a driving slider, the driving slider is provided with a squeezing slope, the squeezing part is laterally slidably engaged with an unlocking switch, one side of the unlocking switch is provided with a squeezing section, the other side of the unlocking switch is provided with an unlocking slope adapted to the squeezing slope, an unlocking spring is provided between the unlocking switch and the squeezing part, the unlocking spring pushes the unlocking switch to move away from the driving slider, the driving slider slides towards one end of the driving cord, pressing the unlocking switch, the unlocking slope pushes the squeezing slope, causing the driving slider to slide away from the driving cord.

[0011] By pushing the squeezing slope through the unlocking slope of the unlocking switch, the drive slider can be pushed to slide axially, which in turn pulls the drive cable, causing the spring limit pin to move, making the control simpler and more efficient.

[0012] Preferably, each end of the handle body is provided with a handle cavity groove, and each of the two handle cavity grooves is provided with a spring limiting pin. The two drive cords extend from the two spring limiting pins to the squeezing part, and the ends of the two drive cords are respectively connected to the two drive sliders. The unlocking switch is symmetrically provided with two unlocking inclined surfaces, and the two unlocking inclined surfaces correspond one-to-one with the squeezing inclined surfaces provided on the two drive sliders.

[0013] The two unlocking ramps and two drive sliders enable simultaneous control of two drive cables, and the pressure on both sides of the unlocking switch is more balanced.

[0014] Preferably, the pressing part is disposed in the sliding positioning groove, one side of the unlocking switch extends slidably from the opening of the sliding positioning groove into the interior, the driving slider slides along the length direction within the sliding positioning groove, and the unlocking spring is disposed between the two driving sliders, with both ends of the unlocking spring abutting against the bottom of the sliding positioning groove and the unlocking switch, respectively. This facilitates more stable sliding of the two driving sliders.

[0015] Preferably, the handle body has an inner channel, and the drive cable extends from the drive slider through the inner channel to the spring limiting pin. This avoids interference with external structures.

[0016] The beneficial effects of this utility model are:

[0017] The relative angle between the handle body and the base is locked and unlocked by a drive slider, which is simple to combine, low in cost, more stable and robust, and more efficient and convenient in the control process. Attached Figure Description

[0023] To enhance understanding of this utility model, it will be described in further detail below with reference to the accompanying drawings and embodiments. These embodiments are only used to explain this utility model and do not limit the scope of protection of this utility model.

[0024] Example

[0025] like Figure 1 As shown, the handle angle adjustment structure includes a handle body 1 and a base;

[0026] The handle body 1 is provided with a handle turntable 2 at its end. The handle turntable 2 is provided with a handle cavity groove 3 on its surface. The side wall of the handle cavity groove 3 is provided with a limit pin hole 11. A spring limit pin 6 is provided in the limit pin hole 11, pointing into the handle cavity groove 3. The tail end of the spring limit pin 6 is connected to one end of the drive cable 8, and the other end of the drive cable 8 extends to the handle body 1.

[0027] The base is provided with a base turntable 4, and the disc surface of the base turntable 4 is provided with a limiting boss 5 corresponding to the handle cavity groove 3; the base turntable 4 is rotatably engaged with the handle cavity groove 3, and the limiting boss 5 is rotatably engaged with the handle cavity groove 3. The side wall of the limiting boss 5 is provided with a plurality of limiting slots 7 that are adapted to the front end of the spring limiting pin 6.

[0028] In this design, the handle body 1 rotates with the base turntable 4 of the base via the handle disc 2. Therefore, under normal circumstances, the handle body 1 can rotate relative to the base to change its angle. Since the front end of the spring-loaded limiting pin 6 is fitted with the limiting slot 7 located on the side wall of the limiting boss 5, when the front end of the spring-loaded limiting pin 6 is aligned with the limiting slot 7, the front end of the spring-loaded limiting pin 6 will engage in the limiting slot 7, locking the angle of the handle disc 2 relative to the base turntable 4. Changing the angle between the handle body 1 and the base, and the front end of the spring-loaded limiting pin 6 fitting with different limiting slots 7, allows for locking of the handle body 1 at different angles relative to the base. To unlock, pinch the unlock switch and pull the drive cable 8 backward. Releasing the unlock switch releases the drive cable 8, which will re-lock the relative positions of the handle disc 2 and the base turntable 4.

[0029] An inner shaft 9 is provided at the center of the handle cavity groove 3, and the inner shaft 9 is rotatably engaged with the base turntable 4. This allows the handle turntable 2 and the base turntable 4 to rotate more stably relative to each other.

[0030] The side wall of the spring limiting pin 6 is provided with a limiting strip hole 10 along the axial direction. A travel pin passes through the limiting strip hole 10, and the end of the travel pin is fixed to the limiting pin hole 11. This facilitates limiting the forward and backward sliding stroke of the spring limiting pin 6.

[0031] The handle body 1 is provided with a squeezing part 18, and the squeezing part 18 is longitudinally slidably engaged with a drive slider 19. The drive slider 19 is provided with a squeezing inclined surface 12. The squeezing part 18 is laterally slidably engaged with an unlocking switch 13. One side of the unlocking switch 13 is provided with a squeezing section 14, and the other side of the unlocking switch 13 is provided with an unlocking inclined surface 15 adapted to the squeezing inclined surface 12. An unlocking spring 16 is provided between the unlocking switch 13 and the squeezing part 18. The unlocking spring 16 pushes the unlocking switch 13 to move away from the drive slider 19, and the drive slider 19 slides toward one end of the drive cord 8. When the unlocking switch 13 is pressed, the unlocking inclined surface 15 pushes the squeezing inclined surface 12, causing the drive slider 19 to slide away from the drive cord 8.

[0032] By pushing the squeezing slope 12 through the unlocking slope 15 of the unlocking switch 13, the drive slider 19 can be pushed to slide axially, which in turn pulls the drive rope 8, causing the spring limit pin 6 to move, making the control simpler and more efficient.

[0033] The handle body 1 has handle cavity grooves 3 at both ends, and spring limiting pins 6 are respectively provided in the two handle cavity grooves 3. The two drive ropes 8 extend from the two spring limiting pins 6 to the squeezing part 18. The ends of the two drive ropes 8 are respectively connected to the two drive sliders 19. The unlocking switch 13 is symmetrically provided with two unlocking inclined surfaces 15. The two unlocking inclined surfaces 15 correspond one-to-one with the squeezing inclined surfaces 12 provided on the two drive sliders 19.

[0034] The two unlocking ramps 15 and the two drive sliders 19 enable simultaneous control of the two drive cables 8, and the pressure on both sides of the unlocking switch 13 is more balanced.

[0035] The pressing part 18 is disposed in the sliding positioning groove 17. One side of the unlocking switch 13 extends slidably from the opening of the sliding positioning groove 17 into the interior. The driving slider 19 slides within the sliding positioning groove 17 along its length. The unlocking spring 16 is disposed between the two driving sliders 19, with both ends of the unlocking spring 16 abutting against the bottom of the sliding positioning groove 17 and the unlocking switch 13, respectively. This facilitates more stable sliding of the two driving sliders 19.

[0036] The handle body 1 has an inner channel, through which the drive cord 8 extends from the drive slider 19 to the spring limiting pin 6. This avoids interference with external structures.

[0037] The beneficial effects of this utility model are:

[0038] The relative angle between the handle body 1 and the base is locked and unlocked by the drive slider 19. The combination is simple, low cost, better stability and firmness, and the control process is more efficient and convenient.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
