Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a metering box. Background Technique

[0002] For the existing electric meter metering box, its general structure can refer to the prior art with the publication number of CN105182027B. Specifically, a wire passing hole is directly opened on the bottom surface of the box body. When connecting the power supply lead-out wire, it directly passes through the wire passing hole on the bottom surface of the box body and then is connected to the electrical components inside the box body, such as connecting to the circuit breaker inside the box body.

[0003] Since there is no corresponding fixation for the power supply lead-out wire after passing through the wire passing hole, once the power supply lead-out wire is pulled by the outside world, it is extremely easy to cause the connection between the power supply lead-out wire and the electrical components to become loose, and phenomena such as sparks are likely to occur at the contact point, which in turn leads to the phenomenon of poor contact and the phenomenon that the connection part is prone to catch fire. Especially, when the power supply lead-out wire is directly suspended outside the box body, the above phenomena are more serious. Content of the Utility Model

[0004] The purpose of the utility model is to provide a metering box to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a metering box, including a box body, a connecting piece is provided at the wire outlet hole of the box body, and the connecting piece includes a connecting part and a fixing part; the fixing part and the connecting part are connected by an elastic column provided; the fixing part includes a shell and a rubber pad arranged inside the shell; an upper cover is provided at one end of the shell, and a lower cover is provided at the other end of the shell; the upper cover and the lower cover are connected to the shell to squeeze the rubber pad, so that the rubber pad clamps the passing power supply lead-out wire inside the fixing part during the deformation process.

[0006] As a preferred technical solution of the utility model: one end of the elastic column is connected to a first connecting seat provided on the connecting part, and the other end of the elastic column is connected to a second connecting seat provided on the shell.

[0007] As a preferred technical solution of the utility model: both ends of the elastic column are provided with studs, and the studs pass through the first connecting seat and the second connecting seat and are threadedly matched with a first nut provided.

[0008] As a preferred technical solution of the utility model: the connecting part is connected to a second nut through a screw rod passing through the bottom surface of the box body.

[0009] As a preferred technical solution of the utility model: the number of the elastic columns is two, and the two elastic columns are symmetrically installed on both sides of the fixing part.

[0010] As a preferred technical solution of the present utility model: extrusion parts are provided on both the upper cover and the lower cover, and the outer wall surface of the extrusion part is in threaded fit with the inner wall surface of the housing.

[0011] By adopting the above technical solution, the beneficial effect of the present utility model is that when one end of the power supply lead passes through the fixing part and the connecting part and is connected to the wiring terminal in the box body, and then the upper cover and the lower cover are connected to the housing, the rubber pad is used to extrude the power supply lead so as to fix the power supply lead on the fixing part. At this time, when an external force pulls the power supply lead, the fixing part can adaptively elongate under the action of the elastic column to buffer the pulling of the external force on the power supply lead, so as to reduce the problem of the power supply lead falling off from the wiring terminal, and further ensure the circuit safety and reduce the phenomenon of poor contact between the power supply lead and the wiring terminal.

Detailed Description of the Embodiment

[0017] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, in which 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 drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the drawings, and is 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 thus should not be construed as a limitation to the present utility model.

[0018] Please refer to Figures 1-4 For an embodiment provided by the present utility model: a metering box, including a box body 1, a connector 2 is provided at the wire outlet hole of the box body 1, and the connector 2 includes a connecting portion 20 and a fixing portion 23; the fixing portion 23 and the connecting portion 20 are connected by an elastic column 22 provided therebetween; the fixing portion 23 includes a housing 27 and a rubber pad 29 disposed inside the housing 27; an upper cover 210 is provided at one end of the housing 27, and a lower cover 28 is provided at the other end of the housing 27; the upper cover 210 and the lower cover 28 are connected to the housing 27 to squeeze the rubber pad 29, so that the rubber pad 29 clamps the passing power supply lead wire inside the fixing portion 23 during the deformation process.

[0019] In summary, when one end of the power supply lead wire passes through the fixing portion 23 and the connecting portion 20 and is connected to the terminal in the box body 1, then the upper cover 210 and the lower cover 28 are connected to the housing 27 to cause the rubber pad 29 to squeeze the power supply lead wire, so as to fix the power supply lead wire on the fixing portion. At this time, when an external force pulls the power supply lead wire, the fixing portion 23 can adaptively elongate under the action of the elastic column 22 to buffer the pulling of the external force on the power supply lead wire, thus reducing the problem of the power supply lead wire falling off from the terminal, and further ensuring the circuit safety and reducing the phenomenon of poor contact between the power supply lead wire and the terminal.

[0020] Based on this, during the process of road surface repair, temporary power taking, and before the basement is completed, etc., in construction sites where the power cord is easily pulled, since the power supply lead wire of this device is reliably fixed and has an appropriate telescopic ability, it can effectively avoid the phenomenon of loosening between the power supply lead wire and the terminal and the phenomenon of easy ignition at the connection.

[0021] Furthermore, since one end of the elastic column 22 is connected to a first connection seat 24 provided on the connecting portion 20, and the other end of the elastic column 22 is connected to a second connection seat 26 provided on the housing 27, therefore, the elastic column 22 can be movably installed on the connecting portion 20 and the fixing portion 23, which is convenient for the installation and replacement of the elastic column 22.

[0022] Specifically, stud bolts 212 are provided at both ends of the elastic column 22, and the stud bolts 212 pass through the first connecting seat 24 and the second connecting seat 26 and are threadedly engaged with the provided first nuts 213. Therefore, when the elastic column 22 is damaged, it can be easily replaced; at the same time, an elastic column 22 with greater elasticity or an elastic column 22 of different lengths can be selected according to needs. Among them, the material of the elastic column 22 is preferably elastic rubber. During specific use, a certain length is reserved for the power supply lead wire between the fixing part 23 and the connecting part 20, that is, there is a bent part between the fixing part 23 and the connecting part 20 of the power supply lead wire, as Figure 4 shown; therefore, when the power supply lead wire is pulled, the elastic column 22 elongates, and at this time the bent part also elongates accordingly, so as to further reduce the phenomenon that the power supply lead wire falls off due to being pulled.

[0023] In order to facilitate the reliable fixation of the connecting part 20 on the box body 1, the connecting part 20 is connected to the provided second nut 21 through a provided screw rod 25 passing through the bottom surface of the box body 1. In addition, disassembling the second nut 21 facilitates removing the connecting member 2 from the box body 1. Based on this, when the device is in use, the structure of the box body does not need to be changed, so the use cost of the device can be reduced.

[0024] On the basis of the above solution, since the number of the elastic columns 22 is two, and the two elastic columns 22 are symmetrically installed on both sides of the fixing part 23, the two sides of the fixing part 23 can be evenly stressed.

[0025] Furthermore, since the upper cover 210 and the lower cover 28 are both provided with extrusion parts 211, and the outer wall surface of the extrusion part 211 is threadedly engaged with the inner wall surface of the housing 27, therefore, by tightening the upper cover 210 and the lower cover 28, the rubber pad 29 can be extruded, so as to facilitate the deformation of the rubber pad 29. Among them, the length of the extrusion part 211 is greater than the length of the rubber pad 29. Therefore, the longer extrusion part 211 can reliably extrude the rubber pad 29 to cause it to deform, and then fix the power supply lead wire in the fixing part 23.

[0026] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present invention, various changes, modifications, substitutions and variations made to these embodiments still fall within the protection scope of the present invention.
