Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric blankets, and more specifically, to a quick connector. Background Art
[0002] The electric blanket connector is a device that connects the power supply and the electric blanket body, supplies power to the electric blanket body, and is an important component of the electric blanket. Usually, in addition to the connector, there is also a controller between the connector and the power plug, which is used to adjust the working state of the electric blanket; the connector of the prior art is usually connected to the power supply by inserting the card head into the corresponding socket; once the connection is completed and powered on, the electric blanket starts to work to provide warmth for the user. When the user lies on the electric blanket, especially when turning over in deep sleep, the electric blanket may be displaced due to this action; especially in those cases where the electric blanket is not fixed or the fixing method is not stable enough, the displacement is more likely to occur; once the position of the electric blanket is displaced, the plug connected to it may fall off from the socket; the falling off of the plug will cause power interruption, which will affect the normal operation of the electric blanket. Utility Model Content
[0003] In order to overcome the deficiencies of the prior art, the utility model provides a quick connector, which has the advantage of preventing the power connection port from falling off from the inside of the socket when the electric blanket is working, thereby improving the stability of the connector.
[0004] To achieve the above purpose, the utility model provides the following technical solution: a quick connector, comprising:
[0005] plug;
[0006] A power connection port is fixedly installed on the left end of the plug, a socket is movably sleeved on the surface of the power connection port, limiting grooves are provided at both the front and rear ends of the socket, a fixed shell is fixedly installed on the left end of the plug, a spring is elastically connected to the inside of the fixed shell, a limiting block is fixedly installed on the side opposite to the spring, and a push block is fixedly installed on the top of the limiting block.
[0007] As a preferred technical solution of the utility model, an interference groove is provided at the top of the fixed shell, and the push block can move inside the interference groove.
[0008] As a preferred technical solution of the utility model, a power cord is arranged at the right end of the plug, and a connecting wire is arranged at the left end of the socket.
[0009] As a preferred technical solution of the utility model, a sealing groove 1 is provided at the left end of the plug, a sealing ring is arranged inside the sealing groove 1, a sealing groove 2 is provided at the right end of the socket, and fixing grooves are provided at the front and rear ends of the plug and the sealing ring.
[0010] As a preferred technical solution of the utility model, an inserting plate is movably connected inside the fixing groove, a fixing hole is opened on the surface of the inserting plate, and an inserting block is arranged inside the fixing hole.
[0011] As a preferred technical solution of the utility model, both the front and rear ends of the plug are threadedly connected with threaded rods, and a rotating block is fixedly installed on the left end of the threaded rod.
[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0013] 1. The utility model inserts the power connection port into the interior of the socket, and then the push block can be pushed to move, and then the push block will drive the limit block to move. During the movement of the limit block, the spring will be compressed, and then the right end of the socket will contact the left end of the plug, and then the limit groove will be aligned with the limit block, and then the push block can be released, and then the resilience of the spring is used to push the limit block and the push block to move, and then the limit block will enter the interior of the limit groove, and then the power connection port is fixed to prevent the power connection port from falling off from the inside of the socket when the electric blanket is working, thereby improving the stability of the connector.
[0014] 2. The utility model rotates the threaded rod, which then drives the rotating block to rotate. Because the threaded rod is threadedly connected to the plug, the threaded rod moves when it rotates, and the rotating block moves away from the inside of the plug block. Then the limit on the plug block is cancelled, and the operator can then pull the plug block out of the fixing hole, and then the plug plate can be pulled out of the fixing groove, and then the worn sealing ring can be taken out from the inside of the sealing groove one, and then the unused sealing ring can be inserted into the inside of the sealing groove one, thereby ensuring the sealing of the connector, and finally by rotating the threaded rod, the operator can replace the sealing ring conveniently, thereby preventing the fibers on the quilt from passing through the gap between the plug and the socket and entering the inside of the connector, thereby affecting the operation of the connector.

[0035] Through the design of the threaded rod 19 and the rotating block 20, after the insert block 18 is inserted into the fixing hole 17, the threaded rod 19 can be rotated, and then the threaded rod 19 will drive the rotating block 20 to rotate, and then the threaded rod 19 will push the rotating block 20 into the insert block 18, thereby fixing the insert plate 16.
[0036] The working principle and use process of this utility model:
[0037] First, the operator can insert the power connector 3 into the socket 2, and then push the push block 8 to move, and then the push block 8 will drive the limit block 7 to move. During the movement of the limit block 7, the spring 6 will be compressed, and then the right end of the socket 2 will contact the left end of the plug 1, and then the limit groove 4 will be aligned with the limit block 7, and then the push block 8 can be released, and then the resilience of the spring 6 can be used to push the limit block 7 and the push block 8 to move, and then the limit block 7 will enter the inside of the limit groove 4, and then the power connector 3 can be fixed to prevent the power connector 3 from falling off from the inside of the socket 2 when the electric blanket is working. In the process of the right end of the socket 2 contacting the left end of the plug 1, the sealing ring 13 will enter the inside of the sealing groove 2 14, thereby increasing the sealing of the connector. When used for a long time, it may occur Wear, at this time, it is necessary to rotate the threaded rod 19, and then the threaded rod 19 will drive the rotating block 20 to rotate, because the threaded rod 19 is threadedly connected to the plug 1, and then when the threaded rod 19 rotates, it will move, and then the rotating block 20 will move away from the inside of the plug block 18, and then the limit on the plug block 18 will be cancelled, and then the operator can pull the plug block 18 out of the inside of the fixing hole 17, and then the plug plate 16 can be pulled out from the inside of the fixing groove 15, and then the worn sealing ring 13 can be taken out from the inside of the sealing groove 12, and then the unused sealing ring 13 can be inserted into the inside of the sealing groove 12, so as to ensure the sealing of the connector, and then the plug plate 16 can be inserted into the inside of the fixing groove 15 and the plug plate 16 can be fixed, so that the connector can continue to work, and finally the operation process is completed.
