Description

Technical Field

[0001] This utility model relates to the field of blocking device technology, specifically a plug blocking device. Background Technology

[0002] Outgoing line cabinets are switchgear that distribute electrical energy from the busbar. Their main function is to send electrical energy from the 10kV busbar to the power transformer through the switchgear. The trolley in the outgoing line cabinet is also called a handcart. The outgoing line cabinet is equipped with sockets, and the trolley is equipped with plugs. By plugging the plugs into the sockets, power is supplied, ensuring the stable operation of the electrical system.

[0003] When the plug on the trolley is inserted into the socket in the outgoing line cabinet, it is usually plugged in directly without being secured, making it easy for people to pull it out, which can cause the trolley to lose power and affect the stable operation of the electrical system. Therefore, we propose a plug blocking device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a plug blocking device that has the advantages of preventing unauthorized removal of the plug. It solves the problem that when the plug on the trolley is inserted into the socket in the outgoing line cabinet, it is usually inserted directly without being secured, making it easy for the plug to be unplugged, which can cause the trolley to lose power and thus affect the stable operation of the electrical system.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a plug blocking device, comprising a cable outlet cabinet body and a trolley body, wherein a socket is provided on one side of the front of the cable outlet cabinet body, and a plug is provided on one side of the upper surface of the trolley body via a connecting wire, the plug being slidably inserted into the front of the socket, and a blocking mechanism is provided on one side of the front of the cable outlet cabinet body.

[0006] The blocking mechanism includes a housing, a bending stop bar, a rotating rod, a return spring, a connecting rod, and a connecting assembly. The housing is located on the right side of the front of the outlet cabinet body. The left and right sides of the rotating rod are rotatably connected to the left and right side walls of the housing cavity via bearings. One end of the bending stop bar is located on the upper surface of the rotating rod. The return spring is located on the back wall of the housing cavity. The front of the return spring is fixedly connected to one side of the back of the connecting rod. The connecting rod is fixed to the outside of the rotating rod.

[0007] The connecting assembly includes a fixing port, two fixing rods, a rotating rod, a roller, and a pushing plate. The fixing port is opened through the lower surface of the housing, and the two fixing rods are arranged on the left and right sides of the bottom end of the connecting rod.

[0008] By adopting this technical solution, the plug can be locked to the front of the socket, preventing it from being pulled out by the user, which can improve the stable operation of the electrical system.

[0009] Furthermore, a movable opening is provided through the front of the housing, and one side of the curved stop is located inside the movable opening.

[0010] By adopting this technical solution, the movable opening allows for easy bending and flipping of the stop bar, and the length of the movable opening can stably provide the stop bar for flipping.

[0011] Furthermore, the connecting rod is located on the longitudinal central axis of the rotating rod.

[0012] By adopting this technical solution, the rotating rod can be rotated stably, the bending stop can be flipped stably, and the plug can be locked stably, which can improve the stability of the structure and its service life.

[0013] Furthermore, the bottom end of the connecting rod passes through the fixing opening and extends to the lower side, and the shape of the connecting rod is a solid rectangle.

[0014] By adopting this technical solution, the connecting rod is shaped as a solid rectangle, which improves the stability of the connecting rod structure and makes it less prone to deformation.

[0015] Furthermore, the rotating rod is rotatably connected to the opposite side of the left and right fixed rods via bearings, the roller is located on the outside of the rotating rod, and the push plate is located at the front and rear of the upper surface of the trolley body.

[0016] By adopting this technical solution, the rollers can be moved by pushing the plate, which can then flip the bending stop and lock the plug, preventing the plug from being manually pulled out and improving the stable operation of the air system.

[0017] Furthermore, the housing is a hollow rectangular body, and the housing is located on the right side of the socket.

[0018] By adopting this technical solution, the shell is made of stainless steel, which can improve the stability and service life of the object structure.

[0019] Furthermore, a buffer layer, which is a rubber layer, is provided on the outer side of the roller.

[0020] By adopting this technical solution, the cushioning performance of the outer side of the roller is improved, preventing the roller from being damaged by impact.

[0021] Furthermore, the bending stop, the two fixed rods, the connecting rod, the rotating rod, and the swivel rod are all made of stainless steel.

[0022] By adopting this technical solution, the stability and service life of the structure are improved, while making the structure less prone to bending and deformation.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] This plug blocking device works as follows: When the trolley body is pushed backward from the front of the outgoing cabinet and into the cabinet, a push plate on the front side of the trolley body pushes the roller backward. The roller drives the connecting rod to move backward, which in turn drives the rotating rod to rotate. At this time, the return spring is stretched. When the rotating rod rotates, it causes the bending stop to flip to the front of the plug and lock the plug. When the bending stop locks the plug, the trolley body is in a suitable position inside the outgoing cabinet, which can prevent the plug from being manually pulled out of the socket and affecting the stable operation of the electrical system. When the trolley body is pushed out from the front of the outgoing cabinet, the back of the push plate moves away from the front of the roller, the return spring resets, and the return spring's return force drives the connecting rod to rotate, causing the bending stop to flip upward and release the plug. Then, the plug can be easily pulled out from the front of the socket. This improves the safety of the equipment, enhances the reliability of the electrical connection between the outgoing cabinet and the trolley, and prevents the plug from falling off the front of the socket.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1In this embodiment, a plug blocking device includes a cable outlet cabinet body 1 and a trolley body 2. A socket 3 is provided on one side of the front of the cable outlet cabinet body 1. A plug 4 is provided on one side of the upper surface of the trolley body 2 via a connecting wire. The plug 4 is slidably inserted into the front of the socket 3. A blocking mechanism 5 is provided on one side of the front of the cable outlet cabinet body 1. The blocking mechanism 5 can lock the plug 4 in the front of the socket 3 to prevent the plug 4 from being pulled out manually.

[0031] Please see Figures 2 to 3 In order to lock the plug 4 in the front of the socket 3 and prevent the plug 4 from being pulled out by the user, the blocking mechanism 5 in this embodiment includes a housing 51, a bending stop bar 52, a rotating rod 53, a return spring 54, a connecting rod 55 and a connecting assembly. The housing 51 is located on the right side of the front of the outlet cabinet body 1. The left and right sides of the rotating rod 53 are rotatably connected to the left and right side walls of the inner cavity of the housing 51 through bearings. One end of the bending stop bar 52 is located on the upper surface of the rotating rod 53. The return spring 54 is located on the back wall of the inner cavity of the housing 51. The front of the return spring 54 is fixedly connected to one side of the back of the connecting rod 55. The connecting rod 55 is fixed to the outside of the rotating rod 53.

[0032] In this embodiment, the connecting assembly includes a fixing port 561, two fixing rods 562, a rotating rod 563, a roller 564, and a pushing plate 565. The fixing port 561 is opened through the lower surface of the housing 51. The two fixing rods 562 are both located on the left and right sides of the bottom end of the connecting rod 55. A moving port is opened through the front of the housing 51. One side of the bending stop 52 is located inside the moving port. The connecting rod 55 is located on the longitudinal central axis of the rotating rod 53. The bottom end of the connecting rod 55 passes through the fixing port 561 and extends to the lower side. The shape of the connecting rod 55 is a solid rectangular body.

[0033] In this embodiment, when the trolley body 2 is pushed backward from the front of the outgoing cabinet body 1 and into the outgoing cabinet body 1, the pushing plate 565 set on the front side of the upper surface of the trolley body 2 pushes the roller 564 backward. The roller 564 drives the connecting rod 55 to move backward, and then drives the rotating rod 53 to rotate. At this time, the return spring 54 is stretched. When the rotating rod 53 rotates, it drives the bending stop 52 to flip to the front of the plug 4 and lock the plug 4. When the bending stop 52 locks the plug 4, the trolley body 2 is just in a suitable position inside the outgoing cabinet body 1. The return spring 54 can bend and deform. The outgoing cabinet is a switch cabinet that distributes electrical energy from the bus. Its main function is to send electrical energy from the 10kV bus to the power transformer through the switch cabinet. The outgoing cabinet is usually equipped with components such as circuit breakers and current transformers to further distribute electrical energy to various power consumption points.

[0034] In this embodiment, the rotating rod 563 is rotatably connected to the opposite side of the left and right fixed rods 562 via bearings. The roller 564 is located on the outside of the rotating rod 563. The pushing plate 565 is located at the front and rear of the upper surface of the trolley body 2. The housing 51 is a hollow rectangular body located on the right side of the socket 3. A buffer layer made of rubber is provided on the outside of the roller 564. The bending stop 52, the two fixed rods 562, the connecting rod 55, the rotating rod 53, and the rotating rod 563 are all stainless steel rods. When the push plate 565 does not push the roller 564 backward, the lower side of the connecting rod 55 is in a forward tilted state. When the bending stop 52 flips to the front of the bending stop 52 plug 4 and locks the plug 4, the lower side of the connecting rod 55 is in a backward tilted state. When the lower side of the connecting rod 55 is in a backward tilted state, the roller 564 is behind the push plate 565 and has not separated. The length of the connecting rod 55 is sufficient to prevent the roller 564 from separating from the push plate 565 when the bending stop 52 does not lock the plug 4.

[0035] In this embodiment, both the trolley body 2 and the outgoing cabinet body 1 are existing technologies. Their internal structures and working principles will not be described in detail. The trolley body 2 can be pushed out from the front of the outgoing cabinet body 1. The trolley body 2 is inserted into the socket 3 on the front of the outgoing cabinet body 1 through the plug 4 to achieve power supply. The stable insertion of the plug 4 into the socket 3 can improve the stable operation of the electrical system.

[0036] In this embodiment, the trolley (handcart) in the outgoing cabinet is typically composed of conductive, insulating, and mechanical components. These components work together to ensure that the current is not disturbed or lost during transmission. When the trolley is in the working position, both the primary and secondary isolation contacts are closed, thereby achieving power distribution and equipment isolation. Before using the trolley in the outgoing cabinet, ensure that the equipment is in a safe state and avoid plugging or unplugging operations while the equipment is energized. During plugging and unplugging, the equipment should be kept stable and avoid excessive shaking or twisting to prevent damage to the plug or affect the electrical connection. The plug should be inspected and maintained regularly to ensure its good performance and prevent electrical failures caused by plug aging or damage.

[0037] It should be noted that this method can prevent the plug 4 from being manually pulled out of the socket 3, which would affect the stable operation of the electrical system. When the trolley body 2 is pushed out from the front of the outgoing cabinet body 1, the back of the push plate 565 is pushed away from the front of the roller 564, the return spring 54 is reset, and the reset force of the return spring 54 drives the connecting rod 55 to rotate, and drives the bending stop 52 to flip upward and release the plug 4. Then the plug 4 can be easily pulled out from the front of the socket 3.

[0038] The working principle of the above embodiments is as follows:

[0039] When the trolley body 2 is pushed backward from the front of the outlet cabinet body 1 and into the outlet cabinet body 1, the push plate 565 on the front side of the upper surface of the trolley body 2 pushes the roller 564 backward. The roller 564 drives the connecting rod 55 to move backward, and then drives the rotating rod 53 to rotate. At this time, the return spring 54 is stretched. When the rotating rod 53 rotates, it drives the bending stop 52 to flip to the front of the plug 4 and lock the plug 4. When the bending stop 52 locks the plug 4, the trolley body 2 is just positioned. By positioning the plug 4 in a suitable location inside the main body 1 of the outgoing cabinet, it is possible to prevent the plug 4 from being manually pulled out of the socket 3, which would affect the stable operation of the electrical system. When the trolley body 2 is pushed out from the front of the main body 1 of the outgoing cabinet, the back of the push plate 565 is pushed away from the front of the roller 564, the return spring 54 is reset, and the return spring force of the return spring 54 drives the connecting rod 55 to rotate, and drives the bending stop 52 to flip upward and release the plug 4. Then the plug 4 can be easily pulled out from the front of the socket 3.
