Description

Technical Field

[0001] This utility model relates to the field of cabinet door lock technology, specifically a door lock mechanism for server racks. Background Technology

[0002] A server rack is a freestanding or self-supporting enclosure used to house electrical or electronic equipment. It typically consists of a cabinet body and cabinet doors. Locks are often installed between the cabinet doors and the cabinet body to seal the server rack.

[0003] A search revealed a Chinese patent (CN211038160U) that discloses a cabinet door lock. This cabinet door lock has no protruding hooks; only a pair of corresponding locking holes need to be installed on its door panel. Furthermore, the locking holes and the bent part of the cabinet door lock are easy to connect with each other, making it less likely to fail to lock even with slight deformation of the door panel. In addition, this cabinet door lock also has a manual unlocking device, which can unlock it in case of power failure or other accidents. However, the cabinet door lock is easy to open, and the equipment inside the cabinet is easy to be stolen. Therefore, we propose a cabinet door lock mechanism. Utility Model Content

[0004] The technical problem this application aims to solve is that the cabinet door lock is easily opened and the equipment inside the cabinet is easily stolen.

[0005] To solve the above-mentioned technical problems, this application provides a cabinet door lock mechanism, including a door lock installed on the cabinet door. The upper and lower ends of the door lock inside the cabinet are slidably connected to support rods. A first ball is installed on the end of the support rod away from the door lock. The door lock drives the two support rods and the first ball to move towards each other to lock and unlock the cabinet door.

[0006] A limiting mechanism is installed at the top and bottom of the cabinet body. The limiting mechanism drives the first ball to slide so as to achieve the clamping of the cabinet door and the cabinet body when locked.

[0007] Warning lights are mounted on the top of the cabinet.

[0008] A sliding component is disposed inside the limiting mechanism, and the sliding component emits a signal via a warning light when it is pressed.

[0009] In some embodiments, the door lock includes a fixed box, a cylindrical lock is fitted on one side of the fixed box, a toothed cylinder is connected to the side of the cylindrical lock that extends into the fixed box, both ends of the toothed cylinder are engaged with toothed rods, a limit spring is connected between the toothed rods and the fixed box, and the end of the toothed rod away from the toothed cylinder is connected to the end of the support rod that extends into the fixed box.

[0010] In some embodiments, the toothed bars at both ends are arranged in a centrally symmetrical manner with respect to the center point of the toothed cylinder.

[0011] In some embodiments, the toothed bars at both ends are arranged in a centrally symmetrical manner with respect to the center point of the toothed cylinder.

[0012] In some embodiments, the limiting mechanism includes a sliding plate, a buffer spring, and a second ball. The sliding plate is installed inside the cabinet, and a sliding hole adapted to the size of the first ball is opened at the center of the sliding plate. The second ball and the inner wall of the sliding plate are connected by the buffer spring and are in pressure contact with the first ball.

[0013] In some embodiments, the sliding assembly includes a fixed cylinder mounted on the inner wall of the slide plate, a slider slidably connected inside the fixed cylinder, a connecting rod mounted on one side of the slider, the connecting rod extending out of the fixed cylinder and connected to the outer side of the second sphere, and a pressure sensor electrically connected to the warning light is also installed inside the fixed cylinder.

[0014] In some embodiments, a plurality of fixing blocks are sleeved on the outer side of the support rod, and the fixing blocks are installed on the cabinet door.

[0015] This utility model has at least the following beneficial effects:

[0016] The door lock requires no electricity and can only be opened with a key, effectively preventing theft. The lock drives the support rod and the first ball to move in opposite directions, locking and unlocking the cabinet door. A limit mechanism is added; when the cabinet door is slightly deformed and locked, a buffer spring compresses the second ball, which in turn compresses the first ball. This, along with the support rod and lock, presses the cabinet door and cabinet together, preventing dust and water from entering through gaps in the cabinet and ensuring normal operation. A sliding component and warning light are also included. If the cabinet door is significantly deformed or forcibly broken, the first ball compresses the second ball, compressing the buffer spring. The second ball then moves the connecting rod and slider, which in turn presses against a pressure sensor. The pressure sensor activates the warning light to alert staff. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] Please see Figure 1-6 This utility model provides a technical solution: a cabinet door lock mechanism, including a door lock 1 installed on the cabinet door. The upper and lower ends of the door lock 1 are slidably connected to support rods 2 inside the cabinet. Multiple fixing blocks 12 are sleeved on the outer side of the support rods 2. The fixing blocks 12 are installed on the cabinet door to increase the stability of the support rods 2 sliding up and down. A first ball 3 is installed at the end of the support rods 2 away from the door lock 1. The door lock 1 drives the two support rods 2 and the first ball 3 to move towards each other to realize the locking and unlocking of the cabinet door.

[0029] Furthermore, the door lock 1 includes a fixed box 7, a cylindrical lock 8 is mounted on one side of the fixed box 7, a toothed cylinder 9 is connected to the side of the cylindrical lock 8 that extends into the fixed box 7, and toothed rods 10 are engaged at both ends of the toothed cylinder 9. A limit spring 11 is connected between the toothed rods 10 and the fixed box 7. The end of the toothed rod 10 away from the toothed cylinder 9 is connected to the end of the support rod 2 that extends into the fixed box 7. The two toothed rods 10 are centrally symmetrical about the center point of the toothed cylinder 9, and the outer side of the toothed rod 10 is slidably connected to the inner wall of the fixed box 7.

[0030] Limiting mechanism 4 is set at the top and bottom of the cabinet body. The limiting mechanism 4 drives the first ball 3 to slide so as to achieve the clamping of the cabinet door and the cabinet body when locked.

[0031] Furthermore, the limiting mechanism 4 includes a sliding plate 401, a buffer spring 402, and a second ball 403. The sliding plate 401 is installed inside the cabinet. A sliding hole with a size matching the first ball 3 is opened at the center of the sliding plate 401. The second ball 403 and the inner wall of the sliding plate 401 are connected by the buffer spring 402 and are in pressure contact with the first ball 3.

[0032] In use, insert the key into the cylindrical lock 8. The cylindrical lock 8 rotates, causing the gear cylinder 9 to rotate. The gear cylinder 9 causes the two gear rods 10 to move closer to each other. When the gear rods 10 move, they compress the limit spring 11 and cause the two support rods 2 and the first ball 3 to move closer to each other. The first ball 3 disengages from the sliding hole of the slide plate 401. At this time, the cabinet door can be opened. When closing the cabinet door, the cabinet door causes the door lock 1, support rods 2 and the first ball 3 to enter the cabinet. Turn the key in the opposite direction and pull it out from the cylindrical lock 8. The cylindrical lock 8 rotates in the opposite direction, causing the support rods 2 and the first ball 3 to move away from each other, so that the first ball 3 enters the sliding hole of the slide plate 401. When the cabinet door deforms slightly, the first ball 3 contacts the second ball 403. The second ball 403 is compressed by the force of the buffer spring 402. Through the support rods 2 and the door lock 1, the cabinet door and the cabinet body are pressed together, thereby preventing dust and water from entering the cabinet through the gaps between the cabinet body and the cabinet door, ensuring the normal use of the cabinet.

[0033] Warning light 5 is mounted on the top of the cabinet.

[0034] The sliding component 6 is located inside the limiting mechanism 4. When the sliding component 6 is pressed, it sends a signal through the warning light 5.

[0035] Furthermore, the sliding assembly 6 includes a fixed cylinder 601 installed on the inner wall of the slide plate 401. A slider 602 is slidably connected inside the fixed cylinder 601. A connecting rod 603 is installed on one side of the slider 602. The connecting rod 603 extends out of the fixed cylinder 601 and is connected to the outer side of the second ball 403. A pressure sensor 604 electrically connected to the warning light 5 is also installed inside the fixed cylinder 601.

[0036] When the cabinet door is deformed to a large extent and cannot be properly fitted, or when the cabinet door is forcibly broken, the first sphere 3 is pressed against the second sphere 403. The second sphere 403 presses against the buffer spring 402 and causes the connecting rod 603 and the slider 602 to slide. The slider 602 slides and comes into contact with the pressure sensor 604. The pressure sensor 604 is controlled by the pressure to light up the warning light 5, thereby reminding the staff.

The bottom end of the first screw 201 extends into the fixing box 7 and is connected to the toothed rod 10. The top end of the second screw 202 is connected to the first ball 3. The threaded cylinder 203 is threadedly connected to the upper end of the first screw 201 and the lower end of the second screw 202. The nut 204 is located at the top and bottom ends of the threaded cylinder 203 and is threadedly connected to the first screw 201 and the second screw 202 respectively. In use, the length of the support rod 2 can be adjusted by rotating the second screw 202 through the nut 204. It is suitable for cabinets of different heights. The detachable design of the threaded cylinder 203 and the second screw 202 also facilitates storage and transportation.
