Description

Technical Field

[0001] This utility model relates to the field of power converter technology, and in particular to a self-locking structure for a power converter. Background Technology

[0002] A power converter is an electronic device used to convert one type of power source to another to meet the energy requirements of a specific device or system. It is typically used to convert alternating current (AC) to direct current (DC), or from one voltage level to another. A power converter usually consists of three parts: an input terminal, a control circuit, and an output terminal.

[0003] Announcement No. CN222380989U proposes a self-locking structure for a power converter. When using the directional plug on the power converter, rotating the directional plug 90 degrees causes the positioning rod to rise under the reset action of the second spring and insert into the positioning hole. This achieves the function of automatically locking the directional plug of the power converter in use, ensuring the stability of the directional plug when inserted into the power socket, improving safety, and automatically locking the horizontal plug structure during use to ensure the stability of the horizontal plug structure when inserted into the power socket.

[0004] However, during the implementation of this device, the movement of the plug is controlled by a complex structure consisting of multiple springs, which makes the device structure too cumbersome. Furthermore, controlling the movement of different sliders to complete the operation of the device is too troublesome. Therefore, a self-locking structure for the power converter is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a self-locking structure for a power converter that can solve the problems in the background art.

[0010] Preferably, a fixing plate is fixedly connected to the surface of the fixing shell, a slot is provided on the surface of the fixing plate, a transverse plug is slidably connected inside the fixing shell, and a insert is fixedly connected to the surface of the transverse plug.

[0011] Preferably, the bottom of the fixed shell is provided with a sliding groove, and a connecting rod is slidably connected to the inner wall of the sliding groove. The connecting rod is fixedly connected to the horizontal plug.

[0012] Preferably, the surface of the transverse plug is provided with a movable groove, and the inner wall of the movable groove is provided with two slots.

[0013] Preferably, a fixing rod is fixedly connected to the surface of the sliding plate, the surface of the fixing rod is slidably connected to the inner wall of the moving groove, and the fixing rod is slidably connected to the inner wall of the slot.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a self-locking structure for a power converter, including a fixed shell 1, a groove 2 on the surface of the fixed shell 1, a rotating plug 17 inside the groove 2, a mounting shaft 8 fixedly connected to the surface of the rotating plug 17, the surface of the mounting shaft 8 being rotatably connected to the interior of the fixed shell 1, a sliding plate 10 slidably connected to the interior of the fixed shell 1, a limiting rod 9 fixedly connected to the surface of the sliding plate 10, the position of the limiting rod 9 corresponding to the position of the mounting shaft 8, a positioning groove 16 on the surface of the mounting shaft 8, the inner wall of the positioning groove 16 being slidably connected to the surface of the limiting rod 9, the rotation of the mounting shaft 8 being limited by the positioning groove 16 and the limiting rod 9, and a threaded rod 7 threadedly connected to the interior of the fixed shell 1, the threaded rod 7 penetrating to the exterior of the fixed shell 1, the surface of the threaded rod 7 being rotatably connected to the interior of the sliding plate 10.

[0024] A limiting groove 11 is provided inside the fixed shell 1. The inner wall of the limiting groove 11 is slidably connected to the surface of the sliding plate 10. The limiting groove 11 limits and guides the sliding of the sliding plate 10.

[0025] A rubber pad is fixedly connected to the surface of the mounting shaft 8. The rubber pad is in contact with the inside of the fixed housing 1. The rubber pad increases the friction between the mounting shaft 8 and the fixed housing 1, thereby restricting the rotation of the rotary plug 17 and preventing the rotary plug 17 from rotating when the limiting rod 9 moves out of the positioning groove 16.

[0026] A fixing plate 3 is fixedly connected to the surface of the fixing shell 1. A slot 4 is provided on the surface of the fixing plate 3. A horizontal plug 13 is slidably connected inside the fixing shell 1. A insert 18 is fixedly connected to the surface of the horizontal plug 13. The insert 18 corresponds to the slot 4. The slot 4 limits the sliding out of the insert 18, thereby preventing the insert 18 from tilting when sliding out. At the same time, it prevents the fixing plate 3 from blocking the sliding of the insert 18. A sliding groove 5 is provided at the bottom of the fixing shell 1. A connecting rod 6 is slidably connected to the inner wall of the sliding groove 5. The connecting rod 6 is fixedly connected to the horizontal plug 13. The sliding groove 5 and the connecting rod 6 limit and guide the sliding of the horizontal plug 13, thereby controlling the position of the horizontal plug 13 and preventing the horizontal plug 13 from tilting during the sliding process, so that the horizontal plug 13 can slide normally.

[0027] The surface of the horizontal plug 13 is provided with a moving groove 14, and the inner wall of the moving groove 14 is provided with two slots 15. The surface of the sliding plate 10 is fixedly connected with a fixing rod 12, the surface of the fixing rod 12 is slidably connected to the inner wall of the moving groove 14, and the fixing rod 12 is slidably connected to the inner wall of the slot 15.

[0028] Working principle: When the rotary plug 17 needs to be used, the threaded rod 7 is rotated, causing it to move outward from the fixed housing 1. This causes the threaded rod 7 to move the sliding plate 10, which in turn moves the limiting rod 9. The limiting rod 9 slides out of the positioning groove 16 under pressure, and at this point, the limiting rod 9 no longer obstructs the rotation of the mounting shaft 8, allowing the user to rotate the rotary plug 17. The rotary plug 17 rotates 90 degrees. Then, the threaded rod 7 is rotated again, moving it inward from the fixed housing 1. The threaded rod 7 pushes the sliding plate 10, which in turn pushes the limiting rod 9, causing the limiting rod 9 to re-insert into the positioning groove 16, positioning the mounting shaft 8 and locking the rotated rotary plug 17.

[0029] When the sliding plate 10 slides under force, it drives the fixed rod 12 to move, causing the fixed rod 12 to move out of one slot 15. At this time, the fixed rod 12 no longer restricts the sliding of the transverse plug 13. Then, the connecting rod 6 is pushed, causing the connecting rod 6 to move the transverse plug 13 and the insert 18, causing the insert 18 to slide out of the slot 4. At this time, the fixed rod 12 corresponds to another slot 15. The threaded rod 7 is rotated again, causing the sliding plate 10 to drive the fixed rod 12 to move, so that the fixed rod 12 is inserted into the slid slot 15 and locks the transverse plug 13. Thus, by rotating the threaded rod 7, the sliding of the transverse plug 13 can be controlled, which further facilitates the use of the operator and reduces the use of springs and other structures.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
