Description

Technical Field

[0001] This utility model relates to the field of switch cabinet technology, specifically to a switch cabinet designed to prevent accidental opening. Background Technology

[0002] With the continuous development of power systems, the safety and reliability of electrical equipment are receiving increasing attention. As an indispensable part of the power system, switchgear is mainly used to distribute electrical energy, protect circuits from overload or short circuit damage, and safely disconnect the power supply for maintenance or repair work.

[0003] However, in practical applications, the safety performance of switchgear faces numerous challenges, one of the most prominent being the insufficient protection against accidental opening. Traditional switchgear typically uses a simple handle lock structure to connect the cabinet door to the cabinet body. While this design is convenient to operate, it poses significant safety hazards in certain situations. Because the handle of the handle lock generally protrudes from the outer surface of the cabinet door, if an operator accidentally bumps into the handle lock during operation, it may cause the handle to rotate, thereby breaking the locking state between the cabinet door and the cabinet body. Once this happens, not only will the electrical equipment inside the cabinet be exposed to the external environment, increasing the risk of electric shock, but it may also cause circuit failures or even more serious safety accidents.

[0004] Therefore, this application proposes a switchgear to prevent accidental opening in order to solve the above-mentioned technical problems. Utility Model Content

[0005] The main purpose of this utility model is to solve the above-mentioned shortcomings and provide a switch cabinet that prevents accidental opening, thereby reducing the risk of the cabinet door being opened by mistake and thus reducing the probability of related safety accidents.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] An anti-accidental opening switch cabinet includes a cabinet body and a cabinet door hinged to the cabinet body. It further includes: a push-button lock cylinder assembly, which passes through a mounting hole in the cabinet door and includes a fixed cylinder and a pressing cylinder that are interlocked; a spring abutting against both ends of the inner cavity connecting the fixed cylinder and the pressing cylinder; and a engagement transmission assembly located at one end of the fixed cylinder inserted into the pressing cylinder. A handle is fixedly provided at the bottom end of the pressing cylinder outside the cabinet door. A positioning mounting assembly is located at both ends of the push-button lock cylinder assembly and fixedly connected to the cabinet door for fixing the push-button lock cylinder assembly in the mounting hole. A locking assembly is located on the inner surface of the cabinet door and is drively connected to the fixed cylinder, using the rotation of the fixed cylinder as the unlocking force.

[0008] Furthermore, the engagement transmission assembly includes a gear plate fixedly disposed at one end of the fixed cylinder inserted into the pressing cylinder and a ring of teeth fixedly disposed on the bottom surface of the pressing cylinder corresponding to the gear plate.

[0009] Furthermore, the bottom ends of the fixed cylinder and the pressing cylinder are fixedly provided with positioning guide posts, and the two ends of the spring are sleeved on the positioning guide posts.

[0010] Furthermore, the positioning and mounting assembly includes an outer positioning component fixedly disposed on the outer surface of the cabinet door and an inner positioning component fixedly disposed on the inner surface of the cabinet door. The outer positioning component includes a positioning sleeve sleeved on the outer wall of the pressing cylinder and passing through the mounting hole, a mounting skirt fixedly disposed on the outer wall of the positioning sleeve and fixedly connected to the outer surface of the cabinet door, and a through hole opened at the bottom end of the positioning sleeve for the handle to pass through and rotate. The inner positioning component has a similar structure to the outer positioning component, only differing in size.

[0012] Furthermore, the limiting seat includes a base fixedly disposed on the inner surface of the cabinet door and two limiting blocks fixedly disposed on the base. The vertical part of the insertion rod is located between the two limiting blocks, and the horizontal part of the insertion rod is inserted into the limiting blocks.

[0013] Furthermore, a first positioning post is fixedly provided at the top of the insertion rod, and a second positioning post is fixedly provided at the top of the limiting block near the lock box, with a tension spring sleeved between the first positioning post and the second positioning post.

[0014] The beneficial effects of this utility model are reflected in:

[0015] This invention features a push-button lock core assembly consisting of a fixed cylinder, a pressing cylinder, a spring, and a connecting transmission component, installed in a mounting hole. A positioning and mounting component is used to fix the push-button lock core assembly in the mounting hole. A locking component with the rotation of the fixed cylinder as the unlocking force is also provided on the inner surface of the cabinet door.

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] like Figure 1-6As shown, this utility model provides a switch cabinet to prevent accidental opening, including a cabinet body 1 and a cabinet door 2 hinged to the cabinet body 1. It also includes: a push-button lock core assembly 3, which passes through a mounting hole 4 in the cabinet door 2, comprising a fixed cylinder 31 and a pressing cylinder 32 interlocked together, a spring 33 abutting against both ends of the inner cavity connecting the fixed cylinder 31 and the pressing cylinder 32, and a connecting transmission assembly 34 disposed at one end of the fixed cylinder 31 inserted into the pressing cylinder 32. A handle 6 is fixedly disposed at the bottom end of the pressing cylinder 32 outside the cabinet door 2; a positioning mounting assembly 5, disposed at both ends of the push-button lock core assembly 3 and fixedly connected to the cabinet door 2, used to fix the push-button lock core assembly 3 in the mounting hole 4; and a locking assembly 7, disposed on the inner surface of the cabinet door 2 and connected to the fixed cylinder 31 via a transmission, using the rotation of the fixed cylinder 31 as the unlocking force. The engagement transmission assembly 34 includes a gear plate 341 fixedly disposed at one end of the fixed cylinder 31 inserted into the pressing cylinder 32, and a ring of teeth 342 fixedly disposed on the bottom surface of the inner cavity of the pressing cylinder 32 at a position corresponding to the gear plate 341.

[0026] The locking assembly 7 is in a locked state when no external force is applied to the handle 6, and the engagement transmission assembly 34 is in a disengaged state, ensuring that the cabinet body 1 and the cabinet door 2 are locked. When it is necessary to open the locking assembly 7, pressure is first applied to the pressing cylinder 32 through the handle 6, causing the pressing cylinder 32 to move towards the fixed cylinder 31 until the gear plate 341 and the teeth 342 in the engagement transmission assembly 34 engage. At this time, the spring 33 is compressed. Then, while maintaining the pressing pressure, the handle 6 is rotated, which drives the pressing cylinder 32 to rotate. The pressing cylinder 32 drives the fixed cylinder 31 to rotate through the engagement of the gear plate 341 and the teeth 342. The locking assembly 7 uses the rotation of the fixed cylinder 31 as a power source to release the locking state. After the handle 6 is released, the spring 33 extends and returns to its original position, causing the gear plate 341 and the teeth 342 to separate again. Compared to ordinary switch cabinets where the cabinet door 2 can be opened simply by rotating the handle 6, this embodiment requires pressing the handle 6 first, and then rotating the handle 6 while maintaining the pressing pressure, in order to release the locking state of the locking component 7 and thus open the cabinet door 2, which greatly reduces the possibility of accidental opening of the switch cabinet.

[0027] In one embodiment, positioning guide posts 8 are fixedly provided at the bottom ends of the fixed cylinder 31 and the pressing cylinder 32, and the two ends of the spring 33 are sleeved on the positioning guide posts 8.

[0028] With this design, the positioning guide post 8 can further limit the spring 33 and guide the extension and retraction process of the spring 33, preventing the spring 33 from being displaced or bent radially, and improving the stability of the spring 33 during operation.

[0029] In one embodiment, the positioning and mounting assembly 5 includes an outer positioning member 51 fixedly disposed on the outer surface of the cabinet door 2 and an inner positioning member 52 fixedly disposed on the inner surface of the cabinet door 2. The outer positioning member 51 includes a positioning sleeve 511 sleeved on the outer wall of the pressing cylinder 32 and passing through the mounting hole 4, a mounting skirt 512 fixedly disposed on the outer wall of the positioning sleeve 511 and fixedly connected to the outer surface of the cabinet door 2, and a through hole 513 opened at the bottom end of the positioning sleeve 511 for the handle 6 to pass through and rotate. The inner positioning member 52 has a similar structure to the outer positioning member 51, only the size is different.

[0030] With this design, the outer positioning component 51 and the inner positioning component 52 cooperate to fix the push-button lock core assembly 3 in the mounting hole 4. In addition to limiting the pressing cylinder 32, the positioning sleeve 511 also guides the pressing cylinder 32 to move towards the stationary cylinder 31 when it is pressed, thus improving its stability during movement.

[0031] In one embodiment, the locking assembly 7 includes a crank 71 fixedly disposed at the bottom end of the fixed cylinder 31, a slider 72 rotatably disposed at the end of the crank 71, a limiting seat 73 fixedly disposed on the inner surface of the cabinet door 2, a T-shaped insert 74 slidably inserted into the limiting seat 73, a groove 77 opened on the vertical part of the insert 74, a locking tongue 75 fixedly disposed at the end of the insert 74, and a lock box 76 fixedly disposed on the inner wall of the cabinet 1 and engaged with the locking tongue 75. The slider 72 passes through the groove 77.

[0032] With this design, when the fixed cylinder 31 rotates, it drives the rocker handle 71 and the slider 72 to rotate. The slider 72 slides in the slide groove 77 and drives the insertion rod 74 to move on the limit seat 73. In turn, the insertion rod 74 drives the locking tongue 75 to move and move out of the lock box 76, thus releasing the locking state of the locking assembly 7.

[0033] In one embodiment, the limiting seat 73 includes a base 731 fixedly disposed on the inner surface of the cabinet door 2 and two limiting blocks 732 fixedly disposed on the base 731. The vertical part of the insert rod 74 is located between the two limiting blocks 732, and the horizontal part of the insert rod 74 is inserted into the limiting block 732.

[0034] With this design, the T-shaped insert (74) can be securely inserted into the limiting seat 73 by limiting the T-shaped insert (74) through the limiting block 732, and can slide left and right to switch the locking state of the locking assembly 7.

[0035] In one embodiment, a first positioning post 9 is fixedly provided on the top of the insertion rod 74, and a second positioning post 10 is fixedly provided on the top of the limiting block 732 near the lock box 76. A tension spring 11 is sleeved between the first positioning post 9 and the second positioning post 10.

[0036] With this design, when the handle 6 is turned to release the locking assembly 7 from its locked state, the latch 75 moves out of the lock box 76, and the tension spring 11 is in a stretched state. After unlocking is completed, the handle 6 is released, the tension spring 11 retracts and resets, driving the insertion rod 74 to move towards the lock box 76, thereby causing the latch 75 to extend and reset. When it is necessary to lock the cabinet 1 and the cabinet door 2 again, the cabinet door 2 can be closed directly, and the extended latch 75 will re-engage in the lock box 76.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0038] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0039] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, "multiple" refers to two or more. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
