[0003] In order to make the faucet lock structure safer, the present application provides a faucet lock pin structure with high safety.

[0004] The present application provides a high-security faucet lock pin structure, which adopts the following technical solutions:

[0005] A high-security faucet lock pin structure includes an outer shell and a lock pin, wherein the outer shell is provided with a through hole for the lock pin to slide through, and the sliding direction of the lock pin is the same as the axial direction of the through hole. The structure also includes a limit block, a sliding seat and a driving member for driving the limit block to slide, wherein the lock pin is arranged on the sliding seat, and the sliding seat is provided with a groove for the limit block to slide into, and the sliding direction of the limit block is not parallel to the sliding direction of the lock pin, and when the limit block is located in the groove, the lock pin is limited to an unlocked state.

[0006] By adopting the above technical solution, the driving member drives the sliding seat to slide, so that the lock pin slides in the through hole to achieve locking and unlocking. In the unlocked state, the limit block slides into the groove, and the lock pin is limited to the unlocked state. The limit block located in the groove can limit the movement of the lock pin. When riding, the limit block positions the sliding seat, and the lock pin is not easy to pop out of the through hole. The faucet lock remains unlocked, and the lock pin is not easy to become locked due to a malfunction, so that the faucet lock is not easy to get stuck when riding, thereby improving the safety of the faucet lock.

[0007] Optionally, the sliding seat includes a sliding member, a connecting member and a limit spring, the connecting member is provided with a sliding groove for the sliding member to slide, the sliding member is provided with a buffer groove, and the sliding groove has side grooves on two opposite side walls, the limit spring is arranged in the buffer groove, and the radial ends of the limit spring are located in the two side grooves, the elastic force direction of the limit spring is the same as the sliding direction of the sliding member; the groove is arranged on the side wall of the connecting member, and the end of the pin shaft is arranged on the connecting member; and it also includes a sliding drive component that drives the sliding member to slide.

[0008] By adopting the above technical solution, the limit spring is located in the buffer groove and the side groove at the same time, so that the connecting member and the sliding member are connected as a whole, and the connecting member and the sliding member can slide relative to each other to a certain extent along the elastic force direction of the spring. When the sliding drive assembly drives the sliding member to slide, the limit spring can drive the connecting member to slide in the same direction as the sliding direction of the sliding member. When the lock pin is stuck and cannot be ejected or retracted, the connecting member cannot move, but the sliding drive assembly can still drive the sliding member to slide, so that the driving source in the sliding drive assembly works normally and the driving source is not easily damaged.

[0009] Optionally, the driving member is a compression spring, the elastic force direction of the compression spring is the same as the sliding direction of the limit block, a slideway for the limit block to slide is provided in the shell, the compression spring is provided in the slideway, and the compression spring drives the limit block to be located in the groove; a limit groove is provided on the side wall of the sliding member, a positioning block is fixed on the limit block, and when the limit block is located in the groove, the positioning block is located in the limit groove; the side wall of the limit groove away from the through hole is a locking slope, the locking slope is inclined in the direction away from the through hole and close to the positioning block, and the locking slope abuts the positioning block to drive the limit block to slide away from the groove.

[0010] By adopting the above technical solution, the sliding movement of the sliding member drives the sliding movement of the connecting member. When the groove is facing the limit block and the limit block is lifted up by the compression spring and enters the groove, the connecting member is positioned in the unlocked state. When locking, the sliding drive assembly drives the sliding movement of the sliding member, the positioning block abuts against the locking inclined surface, and the locking inclined surface guides the positioning block to disengage from the limit groove. At the same time, the limit block also disengages from the groove, and the connecting member slides close to the through hole. The side wall of the connecting member presses the limit block into the slideway. The limit block slides in and out of the groove through the cooperation of the compression spring and the locking inclined surface. There is no need to set a driving source to drive the limit block to slide, which saves costs.

[0011] Optionally, the contact surface between the positioning block and the locking inclined surface is an arc surface.

[0012] By adopting the above technical solution, the setting of the arc surface enables the sliding of the positioning block on the locking inclined surface to be smoother.

[0013] Optionally, an anti-drop block is provided at the end of the locking pin close to the connecting piece, the side wall of the connecting piece is provided with an anti-drop groove for placing the anti-drop block, and the side wall of the anti-drop groove is provided with an avoidance groove for accommodating the connection between the anti-drop block and the locking pin.

[0014] By adopting the above technical solution, the anti-drop block is placed in the anti-drop groove, and after the shell is closed, the anti-drop block is limited in the anti-drop groove, making the installation of the pin shaft and the connecting piece convenient without the need to use screws to fix them, saving costs and improving assembly efficiency.

[0015] Optionally, the sliding drive assembly includes a cam, a turbine, a worm, a gear mechanism and a stepper motor, the worm is coaxially fixed on the rotating shaft of the stepper motor, the turbine and the worm are meshed for transmission, the turbine is coaxially fixed with the input gear of the gear mechanism, the cam is provided with a gear groove for meshing with the output gear of the gear mechanism, the gear mechanism drives the cam to rotate, a driving groove is provided on the side wall of the sliding member, the cam includes a rotating wheel and an eccentric column, the eccentric column is located in the driving groove, and the rotation of the cam drives the sliding member to slide back and forth.

[0016] By adopting the above technical solution, the stepper motor can be set up so that the faucet lock structure can be driven by electricity, and when used with the circuit board, the faucet lock is more intelligent. The gear mechanism makes it easy to adjust the rotation speed of the cam, and the sliding speed of the pin shaft when unlocking and locking. It is also convenient to adjust the installation position of the stepper motor. When the sliding part slides, the stepper motor drives the cam to rotate through the worm and gear mechanism, and the eccentric column slides in the driving groove and drives the sliding part to slide back and forth, so as to realize the unlocking and locking of the pin shaft.

[0017] Optionally, the driving groove includes a straight groove section and an arc groove section. When the eccentric column is located in the driving groove, the sliding seat and the locking pin are in an unlocked state, the eccentric column abuts against the inner wall of the straight groove section to drive the sliding member to slide, and the stepper motor drives the sliding member to slide back and forth by forward and reverse rotation.

[0018] By adopting the above technical solution, the straight groove section of the driving groove can drive the sliding seat to move when the cam rotates, thereby realizing unlocking and locking. The setting of the arc groove section provides space for the cam to move when the sliding seat is in the locked state, reducing the rigidity force on the motor shaft, thereby protecting the motor.

[0019] Optionally, the buffer groove is provided with protrusions on the side walls at both ends facing the elastic force direction of the limit spring, and the limit spring is sleeved on the protrusions.

[0020] By adopting the above technical solution, the limit spring is not easy to slide out of the buffer groove, and the sliding stability of the sliding member and the connecting member is improved.

[0024] 3. The limit spring connects the connecting piece and the sliding piece into a whole, so that when the cam drives the sliding piece to slide, the connecting piece can also slide in the sliding direction of the sliding piece, thereby realizing unlocking and locking.

DETAILED DESCRIPTION

[0032] The present application is further described in detail below with reference to the accompanying drawings and embodiments.

[0033] The present application embodiment discloses a high-security faucet lock pin structure. Figure 1 , Figure 2The high-security faucet lock pin structure includes a shell 1, a lock pin 2 and a sliding seat 4. The shell 1 is provided with a through hole 11 for the lock pin 2 to slide through. The sliding direction of the lock pin 2 is the same as the axial direction of the through hole 11. The shell 1 provides a stable sliding direction for the lock pin 2.

[0034] Reference Figure 3 The sliding seat 4 includes a sliding member 42, a connecting member 43 and a limit spring 44. The connecting member 43 is provided with a sliding groove 431 for the sliding member 42 to slide. Side grooves 432 are provided on the opposite side walls of the sliding groove 431. A buffer groove 421 is provided on the sliding member 42. The limit spring 44 is located in the buffer groove 421. The elastic force direction of the limit spring 44 is the same as the sliding direction of the sliding member 42. The side walls of the buffer groove 421 at both ends facing the elastic force direction of the limit spring 44 are fixed with protrusions 4211. The limit spring 44 is sleeved on the protrusions 4211. The protrusions 4211 make it difficult for the limit spring 44 to slide out of the buffer groove 421. The limit spring 44 connects the connecting member 43 and the sliding member 42 into a whole, and the connecting member 43 and the sliding member 42 can slide relatively.

[0035] Reference Figure 4 , Figure 5 The high-security faucet lock pin structure also includes a limit block 3 and a compression spring 51. The end of the compression spring 51 abuts against one end of the limit block 3. A slideway 12 for the limit block 3 to slide is provided in the housing 1. The compression spring 51 is arranged in the slideway 12. The end of the compression spring 51 away from the limit block 3 abuts against the inner wall of the slideway 12. The elastic force direction of the compression spring 51 is the same as the sliding direction of the limit block 3. A groove 41 is provided on the sliding seat 4. The notch direction of the groove 41 is perpendicular to the axial direction of the lock pin 2. In the unlocked state, the elastic force of the compression spring 51 drives the limit block 3 to slide into the groove 41. At the same time, under the elastic force of the compression spring 51, the limit block 3 is not easy to slide out of the groove 41, thereby limiting the sliding of the lock pin 2.

[0036] Reference Figure 1 , Figure 2 , Figure 6 The limiting block 3 is fixed with a positioning block 31, and the side wall of the sliding member 42 is provided with a limiting groove 423, the limiting groove 423 is for the positioning block 31 to slide into, and the notch direction of the limiting groove 423 is parallel to the notch direction of the groove 41. The side wall of the limiting groove 423 away from the through hole 11 is a locking inclined surface 4231, and the locking inclined surface 4231 is inclined in the direction away from the through hole 11 and close to the positioning block 31, and the contact surface between the positioning block 31 and the locking inclined surface 4231 is an arc surface. When the sliding member 42 slides, due to the elastic force of the compression spring 51, the limiting block 3 abuts against the locking inclined surface 4231 and slides, and the locking inclined surface 4231 guides the positioning block 31 to slide out of the limiting groove 423, and the limiting block 3 is out of the groove 41 at the same time.

[0037] Reference Figure 1 , Figure 3A side wall of the connecting piece 43 at one end close to the locking pin 2 is provided with an anti-slip groove 433, and an anti-slip block 21 is fixed to the end of the locking pin 2 close to the connecting piece 43. The anti-slip block 21 is clamped in the anti-slip groove 433, and a side wall of the anti-slip groove 433 is provided with an avoidance groove 434 for accommodating the connection between the anti-slip block 21 and the locking pin 2. After the shell 1 is closed, the anti-slip block 21 is limited in the anti-slip groove 433, so that the locking pin 2 is connected to the connecting piece 43.

[0038] Reference Figure 2 , Figure 3 , Figure 4 The sliding drive assembly 6 includes a cam 65, a worm gear 63, a worm gear 62, a gear mechanism 64 and a stepping motor 61. The worm gear 62 is coaxially fixed to one end of the stepping motor 61. The worm gear 63 is meshed with the worm gear 62 for transmission, and the worm gear 63 is meshed with the gear mechanism 64 for transmission. The cam 65 is provided with a gear groove 653 for gear meshing. The gear groove 653 is meshed with the gear mechanism 64 to drive the cam 65 to rotate.

[0039] Reference Figure 3 The side wall of the sliding member 42 is provided with a driving groove 424. The cam 65 includes a rotating wheel 651 and an eccentric column 652 fixed to the side of the rotating wheel 651. The axes of the rotating wheel 651 and the eccentric column 652 are parallel but not overlapped. The eccentric column 652 is slidably connected in the driving groove 424. The cam 65 rotates to drive the sliding member 42 to slide back and forth. The driving groove 424 includes a straight groove section 4241 and an arc groove section 4242 connected to one end of the straight groove section 4241. The driving groove 424 is a "J"-shaped groove. When the eccentric column 652 slides in the straight groove section 4241, the cam 65 rotates to drive the sliding member 42 to slide back and forth. The curvature of the arc groove section 4242 coincides with the rotation trajectory of the eccentric column 652. When the eccentric column 652 slides in the arc groove section 4242, the sliding member 42 does not slide.

[0040] The implementation principle of the high-security faucet lock pin structure of the present application embodiment is as follows: the stepper motor 61 drives the cam 65 to reciprocate through the gear box, and the eccentric column 652 of the cam 65 slides in the straight groove section 4241 in the driving groove 424. When the eccentric column 652 slides to the intersection of the straight groove section 4241 and the arc section, the lock pin 2 is unlocked. At this time, the positioning block 31 is located in the groove 41 under the elastic force of the compression spring 51 and is not easy to slide out of the groove 41. When the cam 65 slides toward the other end of the straight groove section 4241, the sliding member 42 is driven. It slides toward the through hole 11, and the locking pin 2 and the connecting piece 43 also slide toward the through hole 11 under the action of the limit spring 44. At the same time, the locking slope 4231 abuts the positioning block 31 and the positioning block 31 slides toward the highest point of the locking slope 4231. When the fixed outer block is located at the highest point of the locking slope 4231, the limit block 3 disengages from the groove 41. When the cam 65 slides to the other end point of the straight groove section 4241, the sliding piece 42 drives the positioning block 31 to slide out of the locking slope 4231. At the same time, the connecting piece 43 drives the locking pin 2 to slide to the locked state.

[0041] In summary, the high-security handlebar lock pin structure improves safety and reduces potential safety hazards when used by riders.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
