Abstract
Description
Technical Field
[0001] This utility model relates to electrical cabinets, specifically to locks for electrical cabinets. Background Technology
[0002] The appliance cabinet door is installed on the appliance cabinet body, which has a lock base. The appliance cabinet door has a movable lock, and the locking element of the lock is inserted into the lock base to lock the appliance cabinet door. The locking element is inserted into the lock base with a clearance fit, which means the appliance cabinet door is loose relative to the appliance cabinet body, especially when it is windy, and may cause abnormal noise. Utility Model Content
[0003] The technical problem solved by this utility model is that the locking part of the electrical cabinet lock and the lock base have a gap fit, resulting in unstable locking of the electrical cabinet door.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an electrical cabinet lock structure, including a lock base installed on the electrical cabinet body and a lock installed on the electrical cabinet door. The lock includes a lock cylinder and a locking member. The lock cylinder can drive the locking member to move linearly. The lock base is provided with rollers, and there is a gap between the rollers and the lock base. The locking member is elongated and has a lock head. The lock head is L-shaped, and a U-shaped space is formed between the lock head and the locking member. The two ends of the lock head are flared.
[0005] According to the above technical solution, when the appliance cabinet door is closed, the lock cylinder is turned with a key. The lock cylinder drives the locking component, which moves linearly, causing one side wall of the lock head to engage in the gap between the roller and the lock base. Because the end of the lock head is flared, the side wall of the lock head can smoothly engage in the gap between the roller and the lock base. Furthermore, the force exerted by the side wall of the lock head on the roller gradually increases. Finally, the middle part of the lock head makes tight contact with the roller, and the appliance cabinet door is stably locked to the appliance cabinet body.
[0006] The lock cylinder is connected to a gear, and one end of the locking element is connected to a rack. The gear and rack mesh. When the lock cylinder is rotated, the lock cylinder drives the gear, the gear drives the rack, and the rack causes the locking element to move linearly.
[0007] The appliance cabinet door has a double-layer panel structure with a gap between the two layers. The appliance cabinet door has a strip-shaped mounting groove. The rack and gear connected to the locking component are located in the strip-shaped mounting groove. The locking component is located on the inner side of the appliance cabinet door. The lock panel is installed on the outer side of the appliance cabinet door. The lock panel closes the strip-shaped mounting groove. The lock cylinder is located in the lock panel.
[0008] The locking member is provided with a limiting groove, a limiting block is installed on the electric appliance cabinet door through a long bolt, the limiting block is matched in the limiting groove, and the long bolt is connected with the lock panel at the same time. The locking member is linearly displaced, and the limiting block is displaced in the limiting groove. The limiting block is moved up to abut against the upper end of the limiting groove, and the locking member reaches the maximum value of upward movement. The limiting block is moved down to abut against the lower end of the limiting groove, and the locking member reaches the maximum value of downward movement.
[0009] The number of locking members is two, which are distributed on the electric appliance cabinet door in an up-down mode, the locking member is provided with a strip-shaped guide groove, a guide member is matched in the strip-shaped guide groove, and the guide member is installed on the electric appliance cabinet door; the racks of the two locking members are all engaged with the gear. The same gear drives the two locking members to be displaced in opposite directions.
[0010] The lock base is installed on the electric appliance cabinet door on the left side of the electric appliance cabinet, the electric appliance cabinet door on the left side is provided with a step, the lock is installed on the electric appliance cabinet door on the right side, and the left edge of the electric appliance cabinet door on the right side can be matched with the step of the electric appliance cabinet door on the left side. In this way, after the electric appliance cabinet is closed, the left edge of the electric appliance cabinet door on the right side is pressed on the right edge of the electric appliance cabinet door on the left side, the electric appliance cabinet door is locked stably, and the surface is flat.

[0030] Combination Figure 1 , Figures 7 to 11 The appliance cabinet lock structure includes a lock base 20 installed on the appliance cabinet body 10 and a lock installed on the appliance cabinet door. The lock includes a lock cylinder 30 and a locking member 40. The lock cylinder can drive the locking member to move linearly. The lock base is provided with rollers 21, and there is a gap between the rollers and the lock base. The locking member is elongated and has a lock head 41. The lock head is L-shaped, and a U-shaped space is formed between the lock head and the locking member. The two ends 42 of the lock head are flared.
[0031] The lock cylinder 30 is connected to a gear 31, and one end of the locking member 40 is connected to a rack 43, with the gear meshing with the rack.
[0032] like Figure 9 The appliance cabinet door has a double-layer panel structure with a gap between the two layers. The appliance cabinet door has a strip-shaped mounting groove 51. The rack 43 and the gear 31 connected to the locking member 40 are located in the strip-shaped mounting groove. The locking member is located on the inner side of the appliance cabinet door. The lock panel 32 is installed on the outer side of the appliance cabinet door. The lock panel closes the strip-shaped mounting groove. The lock cylinder 30 is located in the lock panel.
[0033] The locking component 40 has a limiting groove 44, and a limiting block 46 is installed on the appliance cabinet door by a long bolt 45. The limiting block fits in the limiting groove, and the long bolt is also connected to the lock panel 32.
[0034] There are two locking components 40, which are distributed one above the other on the appliance cabinet door. Each locking component has a strip-shaped guide groove 47, in which a guide component 48 is fitted. The guide component is installed on the appliance cabinet door. The racks 43 of both locking components mesh with the gears 31.
[0035] like Figures 3 to 6 The lock base 20 is installed on the left side door 60 of the electrical cabinet. The left side door has a step 61. The lock is installed on the right side door 50. The left edge of the right side door can cooperate with the step of the left side door.
