Description

Technical Field

[0001] The present invention relates to the technical field of electrical appliance boxes, in particular to an electrical appliance box connection structure and an electrical appliance box. Background Art

[0002] At present, in order to protect some electrical components on electrical equipment, an electrical box is provided for installing the electrical components. The electrical box is a relatively closed structure, including a box body and a cover body. The box body and the cover body are often fixedly connected by screws to prevent the cover body from falling off, so that it can effectively protect the electrical components.

[0003] In order to protect the casing of electric oil heaters or other heaters containing electrical components, the electrical box is assembled with screws when the cover is installed to achieve the purpose of stable fixation, prevent it from falling off and thus play a role of safety protection. However, adding screws to install is equivalent to adding screw parts and installation steps in the assembly process, which increases the cost of the product and does not meet the current consumer's pursuit of low-cost electric heaters with the same performance. In addition, adding a screw installation structure is nothing more than placing the large head of the screw on the outside, which damages the overall appearance of the box structure and does not meet the modern consumer's pursuit of beauty and refinement.

[0004] To this end, an electrical appliance box connection structure and an electrical appliance box are proposed. Summary of the invention

[0005] The object of the present invention is to provide an electrical appliance box connection structure and an electrical appliance box to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] An electrical box connection structure and an electrical box, comprising an electrical box body and a connection cover plate, wherein a docking support is fixedly installed on the surface of the connection cover plate, a positioning inner groove is provided on the surface of the docking support, a docking inner groove is provided on the surface of the electrical box body, a built-in sliding groove is provided on the inner side of the electrical box body, a built-in sliding rod is slidably connected to the inner wall of the built-in sliding groove, a built-in connecting plate is fixedly installed on the surface of the built-in connecting plate, the surface of the built-in connecting plate is slidably connected to the inner side of the electrical box body, a built-in auxiliary plate is fixedly installed on the surface of the built-in connecting plate, the surface of the built-in auxiliary plate is slidably connected to the inner side of the electrical box body, a guide built-in plate is fixedly installed on the surface of the built-in auxiliary plate, the surface of the guide built-in plate is slidably connected to the inner side of the electrical box body, a built-in sliding rod is also fixedly installed on the surface of the guide built-in plate, and the inner side of the electrical box body is threadedly connected to an external bolt.

[0008] Furthermore, the inner side of the built-in connecting plate is slidably connected with a built-in limiting column, both ends of which are fixedly mounted on the inner side of the electrical box body, and the surface of the built-in limiting column is slidably sleeved with an elastic component, and both ends of the elastic component are respectively fixedly mounted on the surface of the built-in connecting plate and the inner side of the electrical box body.

[0009] Furthermore, a rotating guide ring is rotatably connected to the surface of the external bolt, and a surface of the rotating guide ring is slidably connected to the inner side of the electrical box body.

[0010] Furthermore, a fixed support is fixedly installed on the surface of the electrical box body, a movable support is slidably connected to the surface of the electrical box body, and positioning screw grooves are provided on the surfaces of the movable support and the fixed support.

[0011] Furthermore, a protective support plate is slidably connected to the inner side of the electrical box body, and the surface of the protective support plate is fixedly mounted on the surface of the movable support.

[0012] Furthermore, a limited internal rod is fixedly installed on the inner side of the electrical box body, and the surface of the limited internal rod is slidably connected to the limited internal slide plate. The surface of the limited internal slide plate is slidably connected to the inner side of the electrical box body, and the surface of the limited internal slide plate is fixedly installed on the surface of the movable support.

[0013] Furthermore, the built-in sliding rod is in a pointed shape.

[0014] Furthermore, an external communication groove is opened on the surface of the electrical box body, and an external communication column is bonded and connected to the inner wall of the external communication groove.

[0015] Furthermore, heat dissipation slots are provided on the surface of the electrical box body.

[0016] Furthermore, an external protective plate is fixedly mounted on a side of the external connecting column away from the electrical box body, and the external protective plate is located on the inner wall of the external connecting groove.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. After the electrical box body and the connecting cover plate are connected, the operator can control the external bolt to rotate and move the thread on the inner side of the electrical box body, and then the external bolt drives the rotating guide ring to form an extrusion limit on the guide built-in plate. At this time, the built-in sliding rod can form a fixed limit on the inner wall of the inner groove positioned on the docking pillar, so that the electrical box body and the connecting cover plate are connected and fixed. This operation method not only ensures the ease of docking and installation between the electrical box body and the connecting cover plate, but also ensures that the electrical box body and the connecting cover plate can be easily docked and positioned after the internal devices of the electrical box body and the connecting cover plate are assembled or repaired, which improves the cumbersomeness of the traditional electrical box body and the connecting cover plate using multi-point screws and screwdrivers for coordinated regulation, simplifies the operation effect of the coordinated use between the electrical box body and the connecting cover plate, and ensures the aesthetics of the electrical box body.

[0019] 2. When an external wiring body is needed through the electrical box body, the operator can squeeze the external protective plate on the inner wall of the external connecting groove to separate the external connecting column on the external protective plate from the electrical box body, so that the external wiring body can be quickly docked and installed, and ensure that the external protective plate has a certain dust-proof effect on the external connecting groove when the electrical box body is not in use.

[0020] 3. When docking with the docking inner groove through the docking pillar, the docking pillar will squeeze the pointed built-in sliding rod to move on the inner side of the electrical box body, and then the built-in sliding rod will be squeezed by the docking pillar into the inner side of the electrical box body until the positioning inner groove on the docking pillar matches the built-in sliding rod. The built-in sliding rod is pushed into the inner wall of the positioning inner groove by the elastic performance of the compressed elastic component to form a docking pre-fixing effect.

[0021] 4. By sliding the movable support on the surface of the electrical box body, the fixed support can be positioned at the installation position. When the installation point of the movable support deviates, the movable support can change its position with the fixed support by sliding. BRIEF DESCRIPTION OF THE DRAWINGS
