When the lock cylinder is loose, the handle can be adjusted to form a certain included angle with the other end of the key main body, namely the handle is in a bent handle state, so that frequent hand changing in the process of tightening and loosening the cabinet door lock cylinder by personnel is avoided. By performing the form switching operation on the cabinet door key, the rotating efficiency of the cabinet door key can be effectively improved.

Description

Technical Field

[0001] This utility model belongs to the field of cabinet door key technology, and specifically relates to a cabinet door key. Background Technology

[0002] In the field of DC resistance insulation measurement of medium-voltage motors in nuclear power plants, the current work point is usually located at the upstream medium-voltage switch. The measurement process involves opening the switch's outgoing cable compartment and connecting the meter to the motor's power supply circuit. The switchgear cabinet door key usually has a single-core structure; the key is inserted into the cabinet door lock and needs to be rotated more than ten times to lock or unlock it.

[0003] In actual operation, workers often use "ear keys" or "cross keys" to lock or unlock flat-bottomed keyholes (i.e., loosening and tightening operations). However, this type of key has design limitations. Because it lacks a crank or other mechanism, it can only rotate a maximum of 180° at a time, causing workers to frequently switch hands during operation, which greatly affects operational efficiency.

[0004] In addition to efficiency issues, bolts may develop defects such as stripping due to long-term and frequent use. Furthermore, when the tightening torque of the cabinet door key is large, the existing key is prone to damage when tightening the bolt due to its short lever arm and material, which can generate metal fragments. These fragments pose a risk of introducing foreign objects, which may threaten the safe operation of the nuclear power plant.

[0005] During the cabinet door closing process after work is completed, the cabinet is designed with spring-loaded top posts. If the cabinet door is not closed properly and the top posts are not fully pressed in, the switch will not be able to supply power. Currently, the cabinet door lock is tightened by key, but due to the large elasticity of the top posts, the key tightening force is insufficient, resulting in poor reliability in ensuring a tight cabinet door closure.

[0006] Furthermore, the keys currently used on-site have not undergone standardized procedures such as registration, resulting in inconsistent tool quality and improper tool use, which further increases the uncertainty and potential risks in the work process.

[0007] Therefore, how to improve the turning efficiency of cabinet door keys is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0008] The purpose of this utility model is to provide a cabinet door key that can effectively improve the turning efficiency of the cabinet door key.

[0009] To solve the above-mentioned technical problems, this utility model provides a cabinet door key, including a key body and a handle;

[0010] The key body is L-shaped, with a key head at one end and a first hinge at the other end;

[0011] The handle is in the shape of a straight line, and one end of the handle is provided with a second hinge that is hinged to the first hinge, so as to realize the folding configuration of the handle at the other end of the key body.

[0012] Optionally, in the aforementioned cabinet key, the other end of the handle is provided with a hook for easy connection.

[0013] Optionally, in the above cabinet door key, the key head is a flat round key head or a cross round key head.

[0014] Optionally, in the above-mentioned cabinet door key, one of the first hinge portion and the second hinge portion is a plate-like structure and the other is a mounting base with an embedding groove. The plate-like structure is embedded in the embedding groove, and a pin hole is formed at the relative position of the plate-like structure and the mounting base.

[0015] Optionally, in the cabinet door key described above, the rotating side of the plate-like structure is provided with rounded corners.

[0016] Optionally, in the cabinet key described above, the second hinge portion is rotatable relative to the first hinge portion within a 90° range.

[0017] Optionally, in the above-mentioned cabinet door key, one end of the key body forms a 90° angle with the other end.

[0018] Optionally, in the above-mentioned cabinet door key, the key body and / or the handle are made of aluminum alloy or alloy steel.

[0019] Optionally, in the above-mentioned cabinet door key, the key body and the handle are cylindrical in shape.

[0020] Optionally, in the aforementioned cabinet door key, the handle is provided with anti-slip texture.

[0021] This utility model provides a cabinet door key, the advantages of which are:

[0022] The key consists of two parts: a key body and a handle. The key head is located at one end of the key body, while the handle, which can rotate, is located at the other end, forming a folding handle. When the lock cylinder is tight, the handle should be adjusted to be on the same horizontal line as the other end of the key body (i.e., a straight handle). This increases the rotational lever of the key, preventing the cabinet door from not closing properly due to insufficient tightening force, and making it easier for operators to unlock. When the lock cylinder is loose, the handle can be adjusted to form a certain angle with the other end of the key body (i.e., a bent handle). This avoids frequent hand switching during tightening and loosening of the lock cylinder. By switching the key's configuration as described above, the rotation efficiency of the cabinet door key can be effectively improved. Attached Figure Description

[0038] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0039] The core of this utility model is to provide a cabinet door key that can effectively improve the turning efficiency of the cabinet door key.

[0040] To enable those skilled in the art to better understand the technical solutions provided by this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] For details, please refer to Figures 1-8 The present invention provides a cabinet door key, comprising a key body 100 and a handle 200.

[0042] The key body 100 is L-shaped, with a key head 110 at one end that can be inserted into the lock cylinder to unlock. The other end of the key body 100 has a first hinge part 120.

[0043] The handle 200 is in the shape of a straight line. One end of the handle 200 is provided with a second hinge part 210 that is hinged to the first hinge part 120. The first hinge part 120 and the second hinge part 210 are connected so that the handle 200 can rotate relative to the key body 100, and the handle 200 can be folded at the other end of the key body 100.

[0044] This solution provides a cabinet door key composed of a key body 100 and a handle 200. A key head 110 is located at one end of the key body 100, and the handle 200 is rotatably mounted at the other end of the key body, forming a folding handle. When the lock cylinder is tight, the handle 200 needs to be adjusted to be on the same horizontal line as the other end of the key body 100, i.e., the handle 200 is in a straight handle state. This increases the rotational lever arm of the cabinet door key, preventing the cabinet door from not closing properly due to insufficient tightening force, and facilitating easy unlocking by the operator. When the lock cylinder is loose, the handle 200 can be adjusted to form a certain angle with the other end of the key body 100, i.e., the handle 200 is in a bent handle state, avoiding frequent hand switching during tightening and loosening of the cabinet door lock cylinder. By performing the above-mentioned form switching operation on the cabinet door key, the rotation efficiency of the cabinet door key can be effectively improved.

[0045] Since the handle 200 is rotatably mounted on the key body 100, the volume of the entire cabinet door key structure can be reduced by rotating it, making it more convenient for maintenance personnel to carry.

[0046] In a specific embodiment, the other end of the handle 200 is provided with a hook 220 for easy connection. Multiple cabinet door keys can be hung together using the hook 220 to prevent them from being lost or scattered. Alternatively, a keychain can be hung using the hook 220 for easy carrying and to prevent key loss.

[0047] Specifically, the key head 110 is either a flat round key head or a cross round key head. The appropriate choice can be made according to actual needs, and no further restrictions are made here.

[0048] In a specific embodiment, one of the first hinge portion 120 and the second hinge portion 210 is a plate-like structure, and the other is a mounting base with an embedding groove. The plate-like structure is embedded in the embedding groove, and a pin hole is formed at the relative position of the plate-like structure and the mounting base. The first hinge portion 120 and the second hinge portion 210 are connected by a pin, so that the key body 100 and the handle 200 can rotate around the axis of the pin.

[0049] Furthermore, the rotating side of the plate-like structure is machined with rounded corners, which reduces friction and interference between parts, making the rotation process smoother. In addition, the rounded corner design can also prevent operators from being scratched by sharp edges during use, improving safety.

[0050] When the plate-like structure can rotate in two directions, both sides of the plate-like structure can be machined into rounded corners.

[0051] In a specific embodiment, such as Figure 8 As shown, the second hinge 210 can rotate within a 90° range relative to the first hinge 120. In the straight handle state, the handle 200 and the other end of the key body 100 are on the same horizontal line. In the bent handle state, the handle 200 and the other end of the key body 100 are perpendicular.

[0052] In a specific embodiment, the key body 100 and the handle 200 are made of aluminum alloy or alloy steel. The key body 100 and the handle 200 can be made of the same material or different materials. The alloy steel can be high-strength tool steel or stainless steel. To eliminate the risk of foreign objects, the material of the cabinet key, especially the key body 100, can be high-strength tool steel, and undergo heat treatment and surface treatment to prevent foreign objects from being generated due to wear during use.

[0053] Specifically, the key body 100 and the handle 200 are cylindrical in shape.

[0054] To prevent slippage when unlocking, the handle 200 can be designed with anti-slip texture to improve grip friction.

[0055] The beneficial effects of the technical solution provided by this utility model include:

[0056] 1. Improve work efficiency by changing the form of the cabinet door key and increasing the rotation lever arm to avoid frequent hand switching during the tightening and loosening of the cabinet door lock cylinder;

[0057] 2. Eliminate the risk of foreign objects by optimizing the structural materials to prevent damage to the cabinet door keys;

[0058] 3. Improve reliability: Through architectural design, switch between curved handle and long lever arm straight handle to avoid cabinet door not closing properly due to insufficient tightening force.

[0059] 4. Improve standardization: The development of cabinet door keys is strictly implemented in accordance with industry standards and national standards, and they are managed in the warehouse according to the standards for special tools.
