[0031] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that technical personnel in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
[0032] like Figure 1-8As shown, an electric wire pull box includes a shell 1 and a wire pull slider 2 arranged on the shell 1, the wire pull slider 2 has an unlocking position and a reset position, the shell 1 is provided with a driving component 3 for driving the wire pull slider 2 to slide to the unlocking position, the driving component 3 includes a motor 31, a screw 2 and a transmission component 33 arranged between the motor 31 and the screw 32, the wire pull slider 2 is threadedly matched with the screw 32, when the screw 32 rotates forward under the drive of the motor 31, the wire pull slider 2 slides to the unlocking position, and also includes a reset member 4 for driving the wire pull slider 2 to slide to the reset position, the reset member is arranged by a spring, a connecting column is arranged on the wire pull slider 2, one end of the spring is sleeved on the connecting column, and the other end of the spring is sleeved on the connecting column. The end abuts against the screw, or an installation groove is opened on the screw, and the spring is located in the installation groove. When the wire pull slider 2 slides to the reset position, the screw 32 reverses under the action of the wire pull slider 2. Of course, it is also possible that when the screw rotates forward, the wire pull slider moves to the reset position, and when the screw reverses, the wire pull slider moves to the unlocking position. According to the installation structure setting, the motor 31 drives the screw 32 to rotate through the transmission assembly 33. Because the wire pull slider 2 and the screw 32 are threaded, the wire pull slider 2 slides on the housing 1 and slides to the unlocking position. When the wire pull slider 2 slides to the reset position under the action of the reset member 4, the screw 32 rotates, and the motor 31 does not work, thereby reducing motor loss and extending the service life.
[0033] The shell 1 is provided with a guide groove 11, and the wire pulling slider 2 is provided with a guide block 21. The guide block 21 is slidably set in the guide groove 11. The outer periphery of the wire pulling slider 2 is provided with a buffer 5, and the buffer 5 is located on one side of the guide block 21. The buffer is set by a sealing ring, and can also be set by a rubber pad, etc. As long as it can play a protective buffering role, when the wire pulling slider 2 slides to the unlocking position, the buffer 5 contacts the side wall of the guide groove 11, and the structure of the wire pulling slider 2 is stable when sliding and does not deviate. When sliding to the unlocking position, the buffer 5 contacts the side wall of the guide groove 11, which plays a buffering role without noise, preventing the guide block 21 from colliding with the side wall of the guide groove 11.
[0034] The end of the wire-pulling slider 2 is connected to a wire-pulling arm 6, and the wire-pulling arm 6 slides synchronously with the wire-pulling slider 2. A tension spring 7 is connected between the wire-pulling arm 6 and the wire 10. A mounting plate 8 is also provided. The shell 1 is fixed on the mounting plate 8 by screws.

The hole wall of the mounting hole is supported in the annular groove to prevent the guide tube 81 from being separated from the mounting plate 8. The wire 10 passes through the guide tube 81. When the wire-pulling slider 2 slides, the wire-pulling arm 6 can be driven to slide, thereby driving the wire 10 to move and realize unlocking. When the external wire 10 is stuck by a column, the setting of the tension spring 7 will not affect the movement of the wire-pulling slider 2 and the wire-pulling arm 6, and the tension spring 7 is extended when the wire-pulling slider 2 slides. A T-shaped block 22 is provided at the end of the wire-pulling slider 2, and a T-shaped slot 61 is provided on the wire-pulling arm 6.

An opening is provided on one side of the T-shaped slot 61 to facilitate the T-shaped block 22 to enter and exit the T-shaped slot 61. A limiting groove 611 is provided on the side wall of the T-shaped slot 61, and a limiting protrusion 221 is provided on the T-shaped block 22. The limiting protrusion 221 is inserted into the limiting groove 611. The sliding of the wire-pulling slider 2 drives the synchronous sliding of the wire-pulling arm 6. The cooperation between the limiting groove 611 and the limiting protrusion 221 enables the wire-pulling slider 2 and the wire-pulling arm 6 to only slide without rotating.
[0035] The transmission assembly 33 includes a driving gear 331 and a driven gear 332. The driving gear 331 is arranged on the output shaft of the motor 31, and the driven gear 332 is arranged on the screw 32 and rotates synchronously with the screw 32.
