[0008] An antistatic flat lock includes a lock body shell. A transmission component is rotatably connected inside the lock body shell, and one end of the transmission component extends through to one side of the lock body shell. A handle is rotatably connected to the transmission component via a rotating shaft, and the handle is located inside the lock body shell. A lock cylinder is fixedly connected to the handle. A lock opening is provided on the lock body shell, and the lock cylinder corresponds to the lock opening. A lock groove is opened in the lock opening, and the lock groove matches the lock cylinder. A lock tongue is detachably connected to one end of the transmission component, and the lock tongue is located on one side of the lock body shell. A voltage conductive plate is detachably connected to the lock body shell.
[0009] As a preferred embodiment of this utility model, a limiting protrusion is fixedly connected to the lock body shell, and a limiting block is detachably connected to the transmission component, with the limiting block located between the lock tongue and the lock body shell and corresponding to the limiting protrusion.

[0014] 3. Beneficial effects
[0015] Compared with existing technologies, the advantages of this utility model are:
[0016] (1) In this solution, the lock body shell and the conductive voltage plate are assembled and clamped on the equipment door panel for installation. The conductive voltage plate and multiple grounding points on the door panel are in contact to form a dynamic multi-point grounding system. The transmission component is rotatably installed inside the lock body shell. The handle and the lock tongue are both installed on the transmission component. The handle can drive the lock tongue to rotate through the transmission component to realize the opening and closing of the equipment door panel. During the opening and closing of the door panel, the operator inserts a nickel-plated brass key into the lock cylinder. The key forms a conductive path between the lock body shell, handle, transmission component, lock tongue, and conductive voltage plate in the lock cylinder. When the lock accumulates static electricity, the multiple grounding points on the door panel will automatically adjust the contact pressure to ensure that the static electricity can be quickly and evenly released to the equipment grounding layer, effectively preventing the high voltage discharge phenomenon caused by static electricity accumulation and avoiding damage to the electronic equipment and precision instruments inside the door panel.

[0026] Example:
[0027] Please see Figure 1-4 An antistatic flat lock includes a lock body shell 1, a transmission component 2 rotatably connected inside the lock body shell 1, and one end of the transmission component 2 extending movably through to one side of the lock body shell 1. A handle 3 is rotatably connected inside the transmission component 2 via a rotating shaft, and the handle 3 is located inside the lock body shell 1. A lock cylinder 4 is fixedly connected to the handle 3. A lock opening 5 is provided on the lock body shell 1, and the lock cylinder 4 corresponds to the lock opening 5. A lock groove 6 is opened in the lock opening 5, and the lock groove 6 matches the lock cylinder 4. A lock tongue 7 is detachably connected to one end of the transmission component 2, and the lock tongue 7 is located on one side of the lock body shell 1. A voltage conductive plate 8 is detachably connected to the lock body shell 1.
[0028] In this embodiment, the lock body shell 1 and the voltage conductive plate 8 are assembled and clamped on the equipment door panel for installation. The voltage conductive plate 8 and multiple grounding points on the door panel are in contact to form a dynamic multi-point grounding system. The transmission component 2 is rotatably connected inside the lock body shell 1. The handle 3 and the latch 7 are installed on the transmission component 2. The handle 3 can drive the latch 7 to rotate through the transmission component 2 to control the opening and closing of the equipment door panel. After the equipment door panel is closed, the lock cylinder 4 will correspond to the lock opening 5. The handle 3 rotates on the transmission component 2 and retracts into the lock body shell 1, so that the lock cylinder 4 enters the lock opening 5. The operator inserts a nickel-plated brass key into the lock cylinder 4 and turns the key to make the latch on the lock cylinder 4 engage with the lock groove 6, thereby fixing the handle 3 inside the lock body shell 1 and locking the door panel.
[0029] Specifically, a limiting protrusion 9 is fixedly connected to the lock body shell 1, and a limiting block 10 is detachably connected to the transmission component 2. The limiting block 10 is located between the lock tongue 7 and the lock body shell 1 and corresponds to the limiting protrusion 9.
[0030] In this embodiment, when the handle 3 drives the latch 7 to rotate via the transmission component 2 to open or close the equipment door, the handle 3 will drive the limit block 10 to rotate. The limit protrusion 9 restricts the rotation range of the limit block 10, thereby limiting the rotation angle of the latch 7 and ensuring that the latch 7 can determine the required angle to open or close the equipment door.
[0031] Specifically, one end of the transmission component 2 is threaded with a first screw 11, and the first screw 11 passes through the locking tongue 7.
[0032] In this embodiment, the latch 7 is mounted on the transmission component 2 by the first screw 11, so that the transmission component 2 can stably drive the latch 7 to rotate to open and close the door panel.
[0033] Specifically, a washer 13 is fitted on the circumferential surface of the first screw 11, and the washer 13 corresponds to the locking tongue 7.
[0034] In this embodiment, the washer 13 is disposed between the nut of the first screw 11 and one end of the locking tongue 7, which can ensure the installation effect of the locking tongue 7 on the transmission component 2 through the first screw 11 and prevent the first screw 11 from loosening and affecting the stability of the locking tongue 7.
[0035] Specifically, a second screw 12 is threaded onto the lock body shell 1, and the second screw 12 penetrates the voltage conductive plate 8.
[0036] In this embodiment, the second screw 12 is threaded onto the lock body housing 1 to assemble the voltage conductive plate 8, so that the voltage conductive plate 8 and the lock body housing 1 are stably clamped to the door panel for installation.
[0037] Specifically, the lock body shell 1 is made of PEEK material, and the transmission component 2 and the lock tongue 7 are both treated with 316L surface passivation.
[0038] In this embodiment, the lock body shell 1 is made of PEEK material, which has multiple properties such as wear resistance, high temperature resistance, and fatigue resistance, and has a long service life. The transmission component 2 and the lock tongue 7 are subjected to 316L surface passivation treatment, which can improve corrosion resistance and extend service life.
[0039] Working principle: The lock body shell 1 and the voltage conductive plate 8 are assembled and clamped on the equipment door panel for installation. When the operator inserts the nickel-plated brass key into the lock cylinder 4 to open and close the door panel, the nickel-plated brass key in the lock cylinder 4 forms a conductive path with the lock body shell 1, handle 3, transmission component 2, lock tongue 7, and voltage conductive plate 8. The voltage conductive plate 8 contacts multiple grounding points on the door panel, forming a dynamic multi-point grounding system. The multiple grounding points on the door panel will automatically adjust the contact pressure to ensure that static electricity can be released quickly and evenly.
[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
