Description

Technical Field

[0001] The utility model relates to the technical field of electrical protection, and more specifically, to a protective cover with an anti-mis-touch function. Background Art

[0002] Electrical equipment is a general term for equipment such as generators, transformers, power lines, circuit breakers, etc. in the power system. Chinese name: Electrical equipment; English name: Electrical Equi pment; Nature: General term for the power system; Elements: Electrical insulation safety distance. The "three electrical errors" refer to three common errors that occur in the electrical system. Among them, mis-touch means that during operation or maintenance, the equipment or system is accidentally touched, resulting in its accidental operation or affecting its normal working state, thus directly affecting the safety and stability of the system.

[0003] Regarding the above related technologies, there are the following defects:

[0004] In existing secondary circuits and switchboards, there are often various components such as buttons, operating handles, switches, valves, meters, etc. The general practice on site is to post "Do not touch" safety warning signs near the corresponding components, but the risk of mis-touch cannot be fundamentally solved in terms of intrinsic safety. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a protective cover with an anti-mis-touch function;

[0006] The solution adopted by the utility model to solve the technical problem is:

[0007] A protective cover with an anti-mis-touch function includes a first shell and a second shell that are hinged to each other and form an installation cavity, and a password lock that is used to lock the first shell and the second shell and is detachably installed on the first shell; a lock catch for cooperating with the password lock is provided on the second shell.

[0008] In some possible implementation manners, two groups of installation holes are provided on the first shell, and two groups of elastic insertion pieces adapted to the installation holes are provided on one side of the password lock close to the first shell; the ends of the two groups of elastic insertion pieces far from the password lock respectively pass through the corresponding installation holes and extend into the first shell.

[0009] In some possible implementation manners, a convex block is provided at the end of the elastic insertion piece far from the password lock; the convex blocks on the two groups of elastic insertion pieces are arranged on the side where the two groups of elastic insertion pieces are close to each other.

[0010] In some possible implementation manners, the convex block has a wedge-shaped structure, the side far from the elastic insertion piece is an inclined surface, and the included angle formed with the long direction of the elastic insertion piece is an acute angle.

[0011] In some possible implementations, a fixing device for securing the second housing is provided on the outside of the second housing.

[0012] In some possible implementations, the fixing device includes a fixing block mounted on the outside of the second housing and a connector mounted on the bottom of the fixing block that moves along the Z-axis and X-axis directions.

[0013] In some possible implementations, the connector includes a support frame mounted on the bottom of the fixed block, a threaded post arranged along the Z-axis and screwed into the support frame, a slider fitted on the outside of the threaded post and slidingly engaged with the support frame in the Z-axis direction, and an insert block installed inside the slider and elastically connected to the slider; the insert block is driven to move along the X-axis direction under elastic action.

[0014] In some possible implementations, a groove is provided inside the support frame along the Z-axis, and a slide rail is provided on the outside of the slider to slide in cooperation with the groove.

[0015] In some possible implementations, an opening slot is provided within the slider, the opening of which is located on the side away from the second housing; a spring is installed within the opening slot, and the insert block is installed on the side of the spring near the opening.

[0016] In some possible implementations, the opening groove is a T-shaped groove with an opening at its small end. The spring is located inside the large end of the T-shaped groove, and a limiting block is provided inside the large end. The limiting block is positioned between the insert and the spring.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model uses a first housing and a second housing to protect various buttons, operating handles, switches, valves, meters, and other components. The first and second housings are secured with a combination lock and latch, providing protection for electrical equipment under various working conditions, including operation, testing, and maintenance. The combination lock function prevents accidental contact by non-professionals, which could lead to equipment malfunctions or failures. Furthermore, the combination lock is connected to the first housing using elastic inserts, mounting holes, and protrusions, facilitating its installation and removal. This addresses the common practice in existing secondary circuits and control panels where various buttons, operating handles, switches, valves, meters, and other components are typically marked with "Do Not Touch" safety warnings, which do not fundamentally solve the risk of accidental contact.

[0019] This invention achieves the fixation of the device to the cabinet by the cooperation of the insert block and the cabinet body; by utilizing the elastic force of the return spring and by rotating the threaded column, the position of the insert block can be adjusted according to the needs, making it easy to adapt to cabinets of different sizes and improving adaptability.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] The present invention will now be described in detail.

[0029] like Figures 1-6 As shown:

[0030] A protective cover with anti-accidental contact function includes a first housing 1 and a second housing 2 that are hinged to each other and form a mounting cavity, a combination lock 3 for locking the first housing 1 and the second housing 2 and detachably mounted on the first housing 1; and a latch 4 for cooperating with the combination lock 3 is provided on the second housing 2.

[0031] The sealed cavity formed in this utility model encloses various buttons, operating handles, switches, valves, meters, and other components, and is locked by a combination lock 3. Only authorized personnel with the seal can open it according to the seal. This fundamentally solves the problem of accidental contact and avoids situations where contact affects normal operation. It can meet the protection requirements of electrical equipment under various working conditions such as operation, testing, and maintenance, and has a combination lock 3 function to prevent unauthorized personnel from accidentally touching the equipment and causing abnormalities or malfunctions.

[0032] In some possible implementations, in order to facilitate the insertion of the combination lock 3, two sets of mounting holes 7 are provided on the first housing 1, and two sets of elastic plug-in pieces 5 adapted to the mounting holes 7 are provided on the side of the combination lock 3 near the first housing 1; the ends of the two sets of elastic plug-in pieces 5 away from the combination lock 3 pass through the corresponding mounting holes 7 and extend into the first housing 1 respectively.

[0033] Two sets of mounting holes 7 are set on the first housing 1 and are arranged in parallel in the horizontal direction; two sets of elastic plug-in pieces 5 undergo elastic deformation when entering the mounting holes 7, and after one end passes through the mounting holes 7, they return to their initial state. In this way, the combination lock 3 is fixed to the first housing 1 under the action of the two sets of elastic plug-in pieces 5; the fixing method is simple.

[0034] In some possible implementations, a protrusion 6 is provided at the end of the elastic plug 5 away from the combination lock 3; the protrusions 6 on the two sets of elastic plugs 5 are provided on the side of the two sets of elastic plugs 5 that are close to each other.

[0035] The protrusion 6 has a wedge-shaped structure, with the side away from the elastic insert 5 being an inclined surface, and the angle formed with the longitudinal direction of the elastic insert 5 is an acute angle; the angle is A, A < 90°; further, A = 15-30°;

[0036] After the protrusion 6 enters the first housing 1, the side of the protrusion 6 near the first housing 1 will serve as a limiting surface, preventing the combination lock 3 from separating from the first housing 1.

[0037] The wedge-shaped structure design allows the protrusion 6 and the elastic insert 5 to pass through the mounting hole 7 more easily and to fix the combination lock 3.

[0038] Furthermore, the elastic plug-in piece 5 is made of elastic steel sheet, and the elastic plug-in piece 5 and the protrusion 6 are integrally formed.

[0039] Furthermore, the first housing 1 and the second housing 2 are made of transparent plastic.

[0040] In some possible implementations, in order to effectively install the device inside the relevant cabinet so that it can effectively protect the buttons, switches and other components inside the cabinet that need protection, a fixing device is provided on the outside of the second housing 2 for fixing the second housing 2.

[0041] The specific fixing device consists of two sets, which are set on two sides of the second housing 2 that are parallel to the axis of the mounting hole 7; the two sets of fixing devices are connected to the corresponding two inner sides of the cabinet to fix the device to the cabinet;

[0042] In some possible implementations, in order to make the device applicable to cabinets of different sizes, the fixing device includes a fixing block 8 installed on the outside of the second housing 2, and a plug-in component installed on the bottom of the fixing block 8 that moves along the Z-axis and X-axis directions.

[0043] The connector moves along the X-axis, and during use, the connector can be adjusted according to the horizontal distance between the second housing 2 and the cabinet to achieve connection with the inner side of the cabinet.

[0044] The Z-axis movement of the connector allows it to be adjusted to a position that enables connection between the connector and the inner side of the cabinet, effectively avoiding the need for related pipelines inside the cabinet and greatly improving the applicability of this device.

[0045] In some possible implementations, in order to effectively realize the movement of the connector along the Z-axis and X-axis directions, the connector includes a support frame 9 mounted on the bottom of the fixed block 8, a threaded post 11 arranged along the Z-axis direction and screwed into the support frame 9, a slider 10 fitted on the outside of the threaded post 11 and slidingly engaged with the support frame 9 in the Z-axis direction, and an insert block 12 installed inside the slider 10 and elastically connected to the slider 10; the insert block 12 is driven to move along the X-axis direction under elastic action.

[0046] The fixing block 8 is installed on the outside of the second housing 2, the support frame 9 is installed on the bottom of the fixing block 8, the threaded column 11 is set along the Z-axis direction and one end passes through the bottom of the support frame 9 and extends into the support frame 9, and is screwed into the slider 10 inside the support frame 9; in use, turning the threaded column 11 can drive the slider 10 to move along the Z-axis direction, thereby causing the slider 10 and the insert block 12 elastically connected to the slider 10 to move in the Z-axis direction;

[0047] In some possible implementations, to prevent the slider 10 from rotating about the axis of the threaded post 11, a groove is provided inside the support frame 9 along the Z-axis, and a slide rail is provided on the outer side of the slider 10 to slide in cooperation with the groove. The cooperation between the groove and the slide rail allows the slider 10 to move only along the Z-axis and prevents it from rotating.

[0048] In some possible implementations, in order to effectively realize the movement of the insert 12 in the X-axis direction, an opening groove is provided in the slider 10, and the opening of the opening groove is located on the side away from the second housing 2; a spring 14 is installed in the opening groove, and the insert 12 is installed on the side of the spring 14 near the opening; the opening groove is a T-shaped groove 13, with an opening at its small end, and the spring 14 is located in the large end of the T-shaped groove 13, and a limiting block 15 is provided in the large end, and the limiting block 15 is located between the insert 12 and the spring 14.

[0049] Specifically, an installation groove for mounting the insert 12 is provided on the inner side of the cabinet. The axis of the spring 14 is set along the X-axis. One end of the spring 14 is installed in the large end of the T-slot 13. The limiting block 15 is installed on the other end of the spring 14 and can only move within the large end of the T-slot 13. One end of the insert 12 passes through the opening groove and is connected to the limiting block 15.

[0050] When fixing the device to the cabinet, the control block 12 moves to the second housing 2 side, so that the spring 14 is in a compressed state. When the position of the block 12 matches the mounting groove, the block 12 is no longer under force, and the spring 14 will return to a free state, so that the block 12 is inserted into the mounting groove. After the blocks 12 on both sides are inserted into the mounting groove, the connection between the device and the cabinet can be realized.

[0051] The combination lock in this invention is existing technology, and its internal structure will not be described in detail here.

[0052] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
