Technical Field
[0001] This utility model relates to electrical cabinets, specifically to the door and lock structure of electrical cabinets. Background Technology
[0002] An appliance cabinet includes a cabinet body and a cabinet door. Electrical components are installed inside the cabinet. The cabinet door is hinged to the cabinet body and equipped with a lock. The lock includes a latch base mounted on the cabinet body frame and a latching element mounted on the cabinet door. The latch base is installed on the horizontal frame at the bottom of the cabinet body, and the latching element is vertically mounted on the side edge of the cabinet door. A rack is installed on the upper part of the latching element, which meshes with a gear driven by a key. When the cabinet door is closed and the cabinet body is in the correct position, the key drives the gear, which in turn drives the rack. The rack causes the latching element to descend, and the bottom end of the latching element inserts into the latch base from top to bottom, locking the cabinet door. If the cabinet door is not closed and the cabinet body is not in the correct position, the latching element and the latch base are not aligned vertically, and the descending latching element cannot insert into the latch base, thus the cabinet door cannot be locked. After prolonged use, the cabinet doors of the appliance cabinet will tilt downwards to a certain extent, causing the bottom of the door to rub against or even collide with the bottom horizontal frame of the cabinet. As a result, the cabinet door cannot be closed properly, the locking mechanism cannot be aligned with the locking base, and the appliance cabinet cannot be locked. Utility Model Content
[0003] The technical problem solved by this utility model is that after long-term use, the cabinet door of the appliance cabinet will tilt downward to a certain extent, causing the bottom of the cabinet door to rub against or even collide with the bottom horizontal frame of the cabinet body. As a result, the cabinet door cannot be closed properly, the locking fastener cannot be aligned vertically with the locking base, and the appliance cabinet cannot be locked.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an auxiliary component for an appliance cabinet door lock, installed on the bottom crossbar inside the appliance cabinet door, including a fixing component and an actuating component. The fixing component has a slot that engages with the bottom crossbar inside the appliance cabinet door. The fixing component has a through hole, and the bottom crossbar inside the appliance cabinet door has a screw hole. The actuating component is installed on the fixing component by bolts. The bolts pass through the through hole and are screwed into the screw hole, thus fastening the fixing component and the actuating component to the bottom crossbar inside the appliance cabinet door. The bottom edge of the actuating component has an arc-shaped structure, which can contact the bottom horizontal frame of the appliance cabinet.
[0005] The lock includes a latch base located on the bottom horizontal frame of the appliance cabinet and a latching component installed on the appliance cabinet door. The upper part of the latching component has a rack that meshes with a gear, which is driven by a key. The lower end of the latching component has a roller. When the appliance cabinet door is closed and the appliance cabinet is in the correct position, the key drives the gear, the rotating gear drives the rack, the rack causes the latching component to descend, and the bottom end of the latching component inserts into the latch base from top to bottom, thus locking the appliance cabinet door.
[0006] When the appliance cabinet is closed, if the cabinet door does not sag, the curved structure of the actuator does not contact the bottom horizontal frame of the appliance cabinet, the cabinet door can be completely closed, the latch can descend smoothly, insert into the latch base, and the cabinet door is locked.
[0007] When the appliance cabinet door is closed, if the door is slumped, the curved structure of the actuator contacts the bottom horizontal frame of the cabinet, gradually raising the door to its original height until the cabinet is fully closed. This allows the latch to descend smoothly, insert into the latch base, and lock the cabinet door.
[0008] The actuator is L-shaped, with reinforcing ribs on both the left and right sides. The reinforcing ribs and the bottom surface of the actuator form a fan shape. This structure can strengthen the actuator and keep it structurally stable during long-term contact between the arc-shaped structure and the bottom horizontal frame of the appliance cabinet.
[0009] The actuator has a vertical slot, into which the bolt fits. The vertical slot allows for adjustment of the vertical relative position between the actuator and the fixing component, thus enabling the height of the actuator's arc-shaped structure to adapt to the bottom horizontal frame of the appliance cabinet. After the arc-shaped structure contacts the bottom horizontal frame of the appliance cabinet, the appliance cabinet door can be raised to a height sufficient to completely close the cabinet.
[0010] The contact surface between the fixing component and the actuating component is provided with a first toothed structure, and the contact surface between the actuating component and the fixing component is provided with a second toothed structure. The cooperation between the first toothed structure and the second toothed structure can stabilize the relative position between the fixing component and the actuating component and prevent them from sliding relative to each other.
[0011] The fixing component has vertical limiting strips on both sides, and limiting blocks are provided on the inner side of the vertical limiting strips. The actuator has vertical guide strips on both sides, and the vertical guide strips cooperate in the space formed by the vertical limiting strips and limiting blocks. Since the contact surface between the fixing component and the actuator has a first toothed structure, and the contact surface between the actuator and the fixing component has a second toothed structure, the fixing component and the actuator should be accurately aligned in order to ensure accurate engagement of the first toothed structure and the second toothed structure. Especially when adjusting the height of the actuator, the setting of the vertical limiting strips, limiting blocks and vertical guide strips can ensure accurate alignment between the actuator and the fixing component.
[0012] The auxiliary component of this utility model ensures that the cabinet door can be closed properly when the cabinet door has sagged to a certain extent after long-term use, and that the locking mechanism can be aligned vertically with the locking base to ensure the normal locking of the cabinet door.

The fixing component has a through hole 211. The bottom crossbar inside the appliance cabinet door has a screw hole. The actuator is installed on the fixing component by a bolt 23. The bolt passes through the through hole and is screwed into the screw hole, thus fastening the fixing component and the actuator to the bottom crossbar inside the appliance cabinet door. The bottom edge of the actuator is an arc-shaped structure 221, which can contact the bottom horizontal frame 41 of the appliance cabinet body.
[0035] Combination Figures 5 to 10 The actuator 22 is L-shaped, and reinforcing ribs 222 are provided on the left and right sides of the actuator. The reinforcing ribs and the bottom surface of the actuator form a fan shape.
[0036] The actuator 22 has a vertical strip hole 223, and the bolt 23 is fitted into the vertical strip hole.
[0037] The contact surface between the fixing member 21 and the actuating member 22 is provided with a first toothed structure 212, and the contact surface between the actuating member and the fixing member is provided with a second toothed structure.
[0038] The fastener 21 has vertical limiting strips 213 on its left and right sides, and a limiting block 214 on the inner side of the vertical limiting strip. The actuator has vertical guide strips 224 on its left and right sides, and the vertical guide strips are fitted in the space formed by the vertical limiting strip and the limiting block.
[0039] Combination Figure 1 , Figure 2 , Figures 11 to 15The lock 30 includes a latch base 31 mounted on the bottom horizontal frame 41 of the appliance cabinet 40 and a latch 32 mounted on the appliance cabinet door 10. The upper part of the latch 321 has a rack 321 that meshes with a gear 33, which is driven by a key. The lower end of the latch 322 has a roller 322. When the appliance cabinet door is closed and the appliance cabinet is in the correct position, the key drives the gear, which in turn drives the rack. The rack causes the latch to descend, and the bottom end of the latch inserts into the latch base from top to bottom, locking the appliance cabinet door. A guide 34 is installed on the inner wall of the appliance cabinet door to guide the movement of the latch.
[0040] When the appliance cabinet is closed, if the appliance cabinet door 10 does not sink, the arc-shaped structure 221 of the actuator does not contact the bottom horizontal frame 41 of the appliance cabinet, the appliance cabinet door can be completely closed, the appliance cabinet 40 can be smoothly lowered, inserted into the locking base 31, and the appliance cabinet door is locked.
[0041] When the appliance cabinet is closed, if the appliance cabinet door 10 is sunken, the arc-shaped structure 221 of the actuator contacts the bottom horizontal frame 41 of the appliance cabinet, and the appliance cabinet door is gradually raised to its original height, allowing the appliance cabinet 40 to be completely closed. In this way, the locking element 32 can descend smoothly, insert into the locking base 31, and the appliance cabinet door 10 is locked.
[0042] refer to Figures 3 to 10 The vertical strip hole 223 on the actuator 22 allows for adjustment of the vertical relative position between the actuator 22 and the fixing member 21, thereby enabling the height of the arc-shaped structure 221 of the actuator to adapt to the bottom horizontal frame 41 of the appliance cabinet 40. After the arc-shaped structure 221 contacts the bottom horizontal frame 41 of the appliance cabinet, the height at which the appliance cabinet door 10 is raised is sufficient to completely close the appliance cabinet 40.
