[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] The embodiment of this application is as follows:

[0020] Please see Figures 1-3 , Figure 1 This is a schematic diagram of the overall structure of the power distribution box for power engineering according to this utility model. Figure 2 This is a structural schematic diagram of the control component of this utility model. Figure 3 This is a schematic diagram of the structure of the gear 105 and the limiting head 106 of this utility model. Figure 4 This is a schematic diagram of the structure of the guide seat 107 and the pull rod 108 of this utility model.

[0021] This utility model discloses a power distribution box for electrical engineering, comprising a box body 101, a door body 102, a shaft column 103, a connector 104, a gear 105, a limiting head 106, a guide seat 107, a pull rod 108, a limiting block 109, a spring 110, a linkage plate 111, a control block 112, a limiting groove 113, a protrusion 114, and a handle 115. It solves the safety risk problem of existing technologies where the door lacks a limiting device after opening, allowing it to swing freely and potentially collide with surrounding objects or operators. It is understood that the aforementioned solution can also be used to improve safety.

[0022] In this embodiment, both the box body 101 and the box door body 102 are existing technologies. Through the limiting component, the box door body 102 can be limited when it is opened, which solves the problem that the existing technology has no limiting device after the box door is opened, which makes it easy to swing around and may collide with surrounding objects or operators, thus posing a safety risk.

[0023] The shaft 103 is fixedly connected to the housing 101 and located inside the housing 101. The connecting piece 104 is sleeved on the outside of the shaft 103 and rotatably connected to the shaft 103. The door body 102 is fixedly connected to the connecting piece 104. The gear 105 is sleeved on the outside of the shaft 103 and fixedly connected to the shaft 103. The limiting head 106 is connected to the door body 102 through the control component. The control component is installed on the door body 102 and controls the limiting head 106. 06. The shaft 103 is vertically installed at the opening of the housing 101. The connector 104 connects the door body 102 to the shaft 103. A bearing is installed inside the connector 104, which is sleeved on the shaft 103. The door body 102 is fixedly connected to the connector 104, allowing the door body 102 to rotate around the shaft 103. There are two connectors 104, located on the upper and lower sides of the door body 102 respectively, allowing the door body 102 to move. The 02 can rotate stably around the shaft 103. There are two gears 105, respectively located at the upper and lower ends of the shaft 103. The limiting head 106 has teeth that match those of the gears 105 and can mesh with them. There are two limiting heads 106, which are mounted on the inner side of the door body 102 via a control component. The control component can control the synchronous movement of the two limiting heads 106, achieving the separation of the limiting heads 106 and the gears 105. The gear 105 is fixedly mounted on the shaft 103 and cannot rotate, while the limiting head 106 is mounted on the door body 102 and can rotate with the door body 102. When the limiting head 106 meshes with the gear 105, the door body 102 cannot rotate, thus limiting the door body 102. This solves the problem in the prior art where the door is not limited after opening, making it easy for it to swing freely and potentially collide with surrounding objects or operators, posing a safety risk.

[0024] Secondly, the guide seat 107 is fixedly connected to the door body 102 and located on the side of the door body 102 near the limiting head 106; the pull rod 108 is slidably connected to the guide seat 107 and fixedly connected to the limiting head 106; the elastic element is installed on the pull rod 108; the linkage plate 111 is fixedly connected to the pull rod 108 and located at the end of the pull rod 108 away from the limiting head 106; the control block 112 penetrates the door body 102 and is fixedly connected to the linkage plate 111; the guide seat 107 is installed on the inner side of the door body 102; the pull rod 108 is a cylinder that penetrates the guide seat 107 and is slidably connected to the guide seat 107; the guide seat 107 is a cylindrical cylinder that penetrates the guide seat 107 and is slidably connected to the guide seat 107. There are two of each of the guide rods 107 and 108. The two limit heads 106 are respectively installed at the ends of the two guide rods 108. The guide seat 107 and the guide rods 108 can guide the limit heads 106. There are two sets of elastic elements, which are respectively installed on the two guide rods 108 to provide elastic support for the guide rods 108. The linkage plate 111 connects the ends of the two guide rods 108 together to facilitate the linkage of the two guide rods 108. The door body 102 has a through groove. The control block 112 passes through the through groove and is fixedly connected to the middle of the linkage plate 111. By moving the control block 112, the two limit heads 106 can be controlled to move synchronously.

[0025] Meanwhile, the limiting block 109 is fixedly connected to the pull rod 108 and is located at one end of the pull rod 108 near the limiting head 106; the spring 110 is sleeved on the outside of the pull rod 108 and is located between the guide seat 107 and the limiting block 109. The limiting block 109 is used to limit the spring 110. The spring 110 is in a compressed state and can continuously provide a directional force to the pull rod 108, so that the limiting head 106 can maintain the meshing state with the gear 105. Through the elastic force of the spring 110, the pull rod 108 is elastically supported.

[0026] In addition, the limiting groove 113 is located on the side of the guide seat 107 near the pull rod 108; the protrusion 114 cooperates with the limiting groove 113, the limiting groove 113 is opened on the inner wall of the guide seat 107 along the length direction of the guide seat 107, and the protrusion 114 is arranged on the outer side of the pull rod 108 along the length direction of the pull rod 108. The protrusion 114 is inserted into the limiting groove 113. Through the cooperation between the protrusion 114 and the limiting groove 113, the pull rod 108 is limited, thereby preventing the limiting head 106 from rotating and shifting.

[0027] Finally, the handle 115 is fixedly connected to the door body 102 and is located on the side of the door body 102 near the control block 112. The handle 115 is located on the side of the door body 102 near the control block 112. When moving the control block 112, it is necessary to overcome the elastic force of the spring 110, which is inconvenient for the user to operate. The handle 115 can be used as a support to move the control block 112. The handle 115 facilitates the movement of the control block 112.

[0028] In this embodiment, when opening the door, the operator places their thumb on the handle 115 and their other fingers on the control block 112, then pinches it. This moves the control block 112, causing the linkage plate 111 to move the two pull rods 108. Simultaneously, the two limit heads 106 disengage from the two gears 105. At this time, the door body 102 is unlocked and can be opened freely. After the door body 102 is opened, the operator releases the control block 112. When block 112 is formed, under the elastic force of the spring 110, the pull rod 108 will be automatically pushed to move towards the gear 105, forcing the limiting head 106 to mesh with the gear 105. At this time, the box door body 102 is in a locked state and the box door body 102 can no longer rotate, thus limiting the box door body 102. This solves the problem in the prior art that the box door is easy to swing around after it is opened due to the lack of a limiting device, which may collide with surrounding objects or operators and pose a safety risk.

[0029] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
