Description

Technical Field

[0001] The utility model relates to the technical field of control boxes, and more specifically, to an outdoor weak-current control box. Background Technique

[0002] An electrical control box is a structure in which electronic components such as switchgear, measuring instruments, and protective electrical appliances are assembled in a closed or semi-closed metal box according to electrical wiring requirements.

[0003] When external cables enter the control box, they enter through the cable holes of the control box. When the diameter of the cable is not consistent with the diameter of the cable hole, it is necessary to fill the gap between the cable hole and the cable with sealing putty, so as to reduce the entry of mosquitoes and the like into the control cabinet through the gap between the cable hole and the cable, and reduce the influence of mosquitoes and the like on the electronic components.

[0004] However, the use of sealing putty is troublesome, and when disassembling the cable, the plasticity of the sealing putty decreases due to aging, increasing the difficulty of disassembling the cable.

[0005] This application provides another technical solution to solve this technical problem. Content of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide an outdoor weak-current control box.

[0007] The above technical purpose of the utility model is achieved through the following technical solutions:

[0008] An outdoor weak-current control box includes a box body and a box door. A through hole one is opened on the side wall of the box body. A support plate is fixedly connected inside the box body. A through hole two is opened on the support plate. An activity gap is formed between the support plate and the inner side wall of the box body. An elastic sleeve is arranged in the activity gap. The two open ends of the elastic sleeve are respectively communicated with the through hole one and the through hole two. A control component for deforming the elastic sleeve is arranged inside the box body.

[0009] The utility model is further arranged as: the control component includes a fixed ring and a rotating ring. The fixed ring is fixed at one end of the elastic sleeve and the through hole one.

[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0024] As Figure 1 and Figure 2 shown, the present application provides an outdoor weak current control box, which includes a box body 1 and a box door 2. The box door 2 rotates on the box body 1. The box body 1 is used for placing and installing electronic components. A first through hole 4 is formed in the side wall of the box body 1, and a support plate 3 is fixedly connected inside the box body 1. A second through hole 5 is formed in the support plate 3. The cable will sequentially pass through the first through hole 4 and the second through hole 5 and enter the box body 1 to be connected to the electronic components inside the box body 1.

[0025] As Figure 2 shown, an activity gap is formed between the support plate 3 and the inner side wall of the box body 1. An elastic sleeve 6 is arranged in the activity gap. The length of the elastic sleeve 6 is greater than the length between the support plate 3 and the inner side wall of the box body 1. A control component is arranged inside the box body 1. The control component includes a fixed ring 7 and a rotating ring 8. The fixed ring 7 is fixed at one end of the elastic sleeve 6 and the first through hole 4. The rotating ring 8 is fixed at the other end of the elastic sleeve 6. While the rotating ring 8 is rotatably arranged in the second through hole 5, it is also slidably connected to the second through hole 5. Anti-slip lines are formed on the outer side of the rotating ring 8, and the anti-slip lines can increase the friction between the hand and the rotating ring 8, facilitating the operator to perform the rotation operation. The two open ends of the elastic sleeve 6 are respectively communicated with the first through hole 4 and the second through hole 5. When the wire harness enters the box body 1, the cable passes through the elastic sleeve 6 at the same time.

[0026] As Figure 2 and Figure 3 and Figure 4As shown in the figure, several card slots 9 are formed on the side wall of the rotating ring 8, and a sliding slot 10 is formed in the support plate 3. The sliding slot 10 communicates with the through hole. An elastic component is arranged in the sliding slot 10. The elastic component includes a spring 11 and a sliding frame 12. The sliding frame 12 is slidably arranged in the sliding slot 10. Two ends of the spring 11 are respectively connected with the sliding frame 12 and the side wall of the sliding slot 10. A convex block 13 is formed on the sliding frame 12. In the initial state, the sliding frame 12 will slide due to the elastic force of the spring 11, so that the convex block 13 remains in the state of sliding into the card slot 9. One side of the card slot 9 is formed with an inclined surface I, and one side of the convex block 13 is formed with an inclined surface II with the same inclination angle as the inclined surface I. When pressure is applied to the inclined surface II and the inclined surface I, through the interaction of forces, the sliding frame 12 will slide against the elastic force of the spring 11, so that the convex block 13 slides out of the card slot 9, enabling the rotating ring 8 to rotate unidirectionally in this state.

[0027] When installing the cable, pass the cable into the box body 1 through the through hole I 4, the elastic sleeve 6 and the through hole II 5, and directly rotate the rotating ring 8. By using the unidirectional rotation, as well as the deformation and elasticity of the elastic sleeve 6, the elastic sleeve 6 is twisted, reducing the cross-sectional size of the channel in the elastic sleeve 6 until the elastic sleeve 6 closely adheres to the surface of the cable, reducing the gap between the elastic sleeve 6 and the cable. After stopping the rotation, due to the action of the convex block 13 and the card slot 9, the rotating ring 8 cannot rotate in the reverse direction, enabling the elastic sleeve 6 to closely adhere to the surface of the cable, reducing the probability of mosquitoes entering the box body 1 through this gap.

[0028] When the cable needs to be disassembled, push the sliding frame 12 against the elastic force of the spring 11, so that the convex block 13 slides out of the card slot 9, and rotate the rotating ring 8 to release the torsion of the elastic sleeve 6, so that the elastic sleeve 6 does not closely adhere to the surface of the cable. At this time, slide the cable out of the box body 1 through the through hole I 4, the elastic sleeve 6 and the through hole II 5 to complete the disassembly of the cable.

[0029] In summary, for the control box provided in this embodiment, the elastic sleeve 6 can block mosquitoes, making it difficult for mosquitoes to enter the box body 1 through the through hole I 4. Moreover, when disassembling and installing a new cable, the operation is convenient, and the elastic sleeve 6 can be reused.

[0030] The above description is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. Any technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
