Abstract
Description
Technical Field
[0001] This application relates to a shockproof panel lock, belonging to the field of lock technology. Background Technology
[0002] Panel locks are common in everyday and industrial settings, such as on safes, car doors, and panels of large facilities. They lock doors and cabinets by using a handle and lock cylinder assembly in conjunction with the panel. Typically, the handle is installed on the panel, and the lock cylinder assembly is then installed on the handle, or the handle and lock cylinder assembly are installed in different positions on the panel. However, regardless of the method, the installation process relies heavily on mechanical components such as pins and screws. As the facility moves, this purely mechanical installation can lead to abnormal noises, loosening, or even detachment due to vibration, compromising security and potentially causing locking failure. Utility Model Content
[0003] In view of this, this application provides a shockproof panel lock with a stable overall structure, which is not easily shaken off and will not produce abnormal noise.
[0004] Specifically, this application is implemented through the following scheme:
[0005] A shockproof panel lock includes a panel, a handle, and a lock cylinder assembly.
[0006] The panel is provided with a handle mounting slot, a locking slot one, and a locking slot two.
[0007] The handle includes a lever end and a toggle end. The toggle end is installed in the handle mounting groove by a pin, and a lock cylinder base is provided on the lever end.
[0008] The pin is fitted with a latch, one end of which is engaged with the actuating end, and the other end extends through the locking groove to the back of the panel, forming a locking structure with the locking groove.
[0009] Torsion springs are fitted on the pins on both sides of the latch. One end of the torsion spring abuts against the inside of the handle to pre-tighten the handle and prevent abnormal noise. The other end of the torsion spring abuts against the handle mounting groove to form a fastening point between the torsion spring and the panel. The torsion spring, the handle, and the handle mounting groove form a shock-absorbing structure.
[0010] The lock cylinder assembly is mounted on the lever end via a lock cylinder base, and its bottom passes through the second locking groove, forming a locking structure with the key and the second locking groove.
[0011] Furthermore, as a preferred option:
[0012] A retaining plate is installed on the lock cylinder assembly, located between the lock cylinder assembly and the second locking groove. More preferably, the retaining plate is provided with a first retaining hole and a second retaining tongue. The first retaining hole is a U-shaped open through hole extending downward from the top of the retaining plate, and the first retaining hole is fitted onto the outer periphery of the lock cylinder assembly. The second retaining tongue is formed by bending the end of the retaining plate below the second retaining hole towards the side away from the handle. During installation, the retaining plate is pushed from bottom to top, and the retaining plate is fitted onto the lock cylinder assembly near the inner wall of the handle through the first retaining hole, thereby fixing the lock cylinder assembly and preventing the lock cylinder assembly from loosening from the lock cylinder base under vibration. Preferably, it also includes a second retaining hole, which is located below the first retaining hole and is a horizontally elliptical through hole. The second retaining hole may or may not be connected to the first retaining hole.
[0013] The aforementioned card plate, in conjunction with the torsion spring, provides shock resistance for the entire panel lock.
[0014] The bottom of the lock cylinder assembly is provided with an oblong lock hole, which engages with the second locking groove to achieve 90˚ fixed-angle rotation unlocking of the lock cylinder assembly.
[0015] The latch includes a fulcrum end and a locking end. A pin hole is provided near the fulcrum end, through which a pin passes. A torsion spring is fitted on the pins on both sides of the pin hole. The fulcrum end is engaged with the actuating end and swings relative to the pin as the actuating end pushes it. The locking end is located on the side of the latch near the locking groove one. It has an irregular cross-section that gradually increases and then decreases again. The part corresponding to the larger cross-section passes through the locking groove one and protrudes on the back of the panel. The fulcrum end swings relative to the pin, causing the locking end to move relative to the locking groove one. The handle engages with the latch to unlock the latch in the locking groove one position.
[0016] The lock cylinder assembly and the second locking groove are sealed with an EPDM gasket.
[0017] The latch and the locking groove are sealed with an EPDM gasket.
[0018] The pin is sealed to the side wall of the handle mounting groove with an O-ring.
[0019] The lock cylinder assembly and the lock cylinder base are sealed with an O-ring.
[0020] The back of the panel is fitted with a pad.
[0021] The aforementioned gaskets and sealing rings achieve a complete seal for the entire panel lock, and the sealed panel lock meets the IP65 protection requirements.
[0022] A sealing plug is installed on the back of the panel. Attached Figure Description

[0035] This embodiment provides a shockproof panel lock. The embodiment of this application is described below with reference to the accompanying drawings.
[0036] See Figure 1 , Figure 2 , Figures 1 to 2 A diagram illustrating this embodiment is shown.
[0037] This embodiment of the shockproof panel lock includes a panel 1, a handle 2, and a lock cylinder assembly 3.
[0038] The panel 1 is recessed towards the back to form a handle mounting groove 11. The handle mounting groove 11 is provided with a locking groove 12 and a locking groove 2 13, both of which are rectangular grooves.
[0039] The handle 2 includes a lever end 21 and a toggle end 22. The lock cylinder base 31 is mounted on the lever end 21 of the handle 2, and the toggle end 22 is mounted in the handle mounting groove 11 by a pin 6.
[0040] Combination Figures 3 to 5 The lock cylinder assembly 3 is installed on the lock cylinder base 31. The bottom of the lock cylinder assembly 3 is provided with a waist-shaped lock hole 32, which is locked in the locking groove 13. By rotating the lock cylinder assembly 3 with the key, the waist-shaped lock hole 32 is rotated 90˚, which can realize the rotational unlocking between the lock cylinder assembly 3 and the panel 1. At this time, the lever end 21 of the handle 2 is in an active state. By levering the lever end 21, the handle 2 can be rotated counterclockwise relative to the pin.
[0041] Both the torsion spring 5 and the latch 7 are mounted on the pin 6, in combination. Figures 3 to 6 The former enables reset and shock absorption, while the latter enables unlocking and locking. Specifically:
[0042] Unlocking and unlocking process: The latch 7 has a V-shaped structure with a pin hole 71 at the top. The pin 6 passes through the pin hole 71, and the latch 7 is installed between the handle 2 and the handle mounting groove 11. The top of the latch 7 has an arc-shaped protrusion forming a fulcrum end 72. The upper end of the handle 2, i.e., the actuating end 22, is shaped to match the latch 72, so that the two are connected. When the handle 2 rotates counterclockwise relative to the pin, the actuating end 22 pushes the fulcrum end 72 to move in the same direction, and drives the entire latch 7 to rotate counterclockwise relative to the pin 6. The side of the latch 7 near the locking groove 12 has an irregular cross-section that gradually increases and then decreases again, which is the locking end 73. The part corresponding to the larger cross-section of the locking end 73 passes through the locking groove 12 and protrudes on the back of the panel 1. In the locked state, the part corresponding to the larger cross-section is locked on the back of the panel 1. When the latch 7 rotates counterclockwise, it drives the locking end 73 to move relative to the locking groove 12 until it disengages from the locking groove 12, and the panel 1 and the latch 7 are unlocked.
[0043] Reset and shock absorption process: The torsion spring 5 is fitted onto the pins 6 on both sides of the latch 7, with the free end including latch end 1 51 and latch end 2 52, combined with... Figure 5 The second buckle end 52 forms a buckle point on the inner wall of the panel 1. During the unlocking process, the torsion spring 5 is in a compressed deformation state. When the force ends, the torsion spring 5 returns to its original deformation and resets the lock 7 through the force transmission of the pin 6. The first buckle end 51 abuts against the inner wall of the handle 2. Since the handle 2 is installed by the pin 6, the first buckle end 51 of the torsion spring 5 can pre-tighten the handle 2 to prevent abnormal noise from the handle 2 during vibration and displacement.
[0044] Lock cylinder assembly 3 is fixed by the retaining plate 4, combined with Figure 5 , Figure 7 The locking plate 4 is located between the lock cylinder assembly 3 and the locking groove 13. The locking plate 4 has an overall L-shaped structure. Its longitudinal part is provided with a locking hole 41, which is a U-shaped through hole with a flared opening at the top. The two sides of the flared opening are guide sections 45 extending outward. The transverse part is a latch 42 formed by bending the bottom of the longitudinal part laterally. During installation, the locking plate 4 is pushed upward from below the lock cylinder assembly 3, so that the locking hole 41 is engaged with the outer periphery of the lock cylinder assembly 3. The bending direction of the latch 42 is away from the handle 2, which can fix the lock cylinder assembly 3 on the lock cylinder base 31. This structure can prevent the lock cylinder assembly 3 from loosening under vibration.
[0045] Below the first locking hole 41, a second locking hole 43 can also be provided. The second locking hole 43 is also located on the longitudinal part and is a transverse elliptical through hole, which can serve as an auxiliary fixing assembly hole when necessary. The second locking hole 43 can be connected to the first locking hole 41 through the transition slot 44, or they can be disconnected from each other.
[0046] During installation, in order to achieve a seal, combined with Figure 4 and Figure 6The lock cylinder assembly 3 and the lock cylinder base 31 are sealed together by an O-ring 33, and an O-ring 61 is used to seal the connection between the pin 6 and the outer wall of the handle mounting groove 11. An EPDM gasket 34, which can be circular, seals the connection between the lock cylinder assembly 3 and the locking groove 13. An EPDM gasket 74, which can be square, seals the connection between the latch 7 and the locking groove 12. If necessary, a gasket 8 can be fitted onto the back of the panel 1, and the panel 1 and gasket 8 can be secured at the four corners with screws 14. The aforementioned EPDM gasket, gasket, and sealing ring achieve the sealing of the entire panel lock, and the sealed panel lock meets the IP65 protection requirements.
[0047] A plug hole is provided on the back of panel 1. Insert the hook tool into the plug hole and pull one of the legs of torsion spring 5 into torsion spring retaining buckle 75. After installation, seal the plug 9 at the plug hole.
[0048] The above-described embodiments are merely illustrative of several feasible implementations of the present invention, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the present invention, nor are the embodiments intended to limit the scope of protection in the claims of the present invention. For those skilled in the art, various modifications and improvements can be made without departing from the concept of the present invention. All equivalent implementations or changes that do not depart from the present invention should be included in the technology of the present invention.
