[0019] See also Figure 1-2 The utility model provides a technical solution: a cable trench fire retardant coating spraying device, including a connecting sleeve 1 and a locking mechanism 2, a connecting block 3 is fixedly provided on the connecting sleeve 1, the connecting block 3 is fixedly connected to the locking mechanism 2, a groove 4 for a handrail to be placed in the bottom of the connecting sleeve 1 is provided, a stopper groove 6 is symmetrically provided on the inner wall of the groove 4, a stopper 5 for limiting the connecting sleeve 1 is provided in the stopper groove 6, a control groove 10 is provided on the side wall of the stopper 5 located in the stopper groove 6, a connecting rod groove 11 is provided on the inner wall of the stopper groove 6 corresponding to the control groove 10, a connecting rod 12 is slidably provided in the connecting rod groove 11 for controlling the movement of the stopper 5 with the control groove 10, a pressure column groove 13 is provided on the inner wall of the connecting rod groove 11 through the side wall of the connecting sleeve 1, and a pressure column 14 for controlling the movement of the connecting rod 12 is slidably provided in the pressure column groove 13 for controlling the movement of the connecting rod 12

[0020] Specifically, a block spring 7 is fixedly provided in the block groove 6, and the block spring 7 is fixedly connected to the block 5. Through the elastic force of the block spring 7, the block 5 extends out of the block groove 6 and cooperates with the groove 4 to install the connecting sleeve 1 on the handrail.

[0021] Specifically, the inner wall of the stop block 5 close to the groove 4 is in contact with the handrail, and the side wall of the stop block 5 located outside the stop block groove 6 and away from the bottom of the groove 4 is an inclined surface, which is convenient for installing the connecting sleeve 1 on the handrail. During installation, the groove 4 of the connecting sleeve 1 is aligned with the handrail for installation. The inclined surface of the stop block 5 is subjected to the force of the handrail to cause the stop block 5 to compress the stop block spring 7 and slide into the stop block groove 6 until the bottom of the groove 4 is in contact with the handrail. At this time, the stop block 5 slides out under the elastic force of the stop block spring 7 and contacts the surface of the handrail, thereby The connecting sleeve 1 is installed on the handrail, and the contact surfaces with the handrail are the inner wall of the groove 4 and the stop block 5, both of which are smooth surfaces and fit with the handrail, which can greatly reduce the friction loss between the handrail and the connecting sleeve 1. A limiting groove 8 is provided on the inner wall of the stop block groove 6 away from the control groove 10, and a limiting block 9 fixedly connected to the side wall of the stop block 5 is slidably provided in the limiting groove 8. The limiting groove 8 and the limiting block 9 are used to prevent the stop block 5 from sliding out of the stop block groove 6 too much and interfering with the installation of the connecting sleeve 1.

[0022] Specifically, the inner wall of one side of the control groove 10 is an inclined surface, and the connecting rod 12 is symmetrically fixedly connected with an ear plate 18 on one side close to the control groove 10. The ear plate 18 is rotatably connected with a roller 19, and the roller 19 is against the inclined surface of the control groove 10. The movement of the connecting rod 12 drives the roller 19 to move, and acts on the inclined surface of the control groove 10. The roller 19 rolls on the inclined surface of the control groove 10 so that the stop block 5 compresses the stop block spring 7 and slides into the stop block groove 6, thereby allowing the connecting sleeve 1 to be removed from the handrail.

[0023] Specifically, the end of the connecting rod 12 away from the control groove 10 is an inclined surface and abuts against the pressure column 14, and the end of the pressure column 14 abutting against the connecting rod 12 is an inclined surface. Pressing the pressure column 14 acts on the inclined surface of the connecting rod 12 to move the connecting rod 12, thereby controlling the stop block 5.

[0024] Specifically, return grooves 15 are symmetrically provided on the inner wall of the pressure column groove 13, and a return spring 16 is fixedly provided on the inner wall of the return groove 15 near the connecting rod groove 11. The return spring 16 is fixedly connected with a return block 17. The return block 17 is slidably arranged in the return groove 15 and is fixedly connected to the side wall of the pressure column 14. When the pressure column 14 is pressed, the pressure column 14 drives the return block 17 to compress the return spring 16. After the pressure column 14 is released, the pressure column 14 is reset under the elastic force of the return spring 16.

[0025] A specific application example of this embodiment is:

[0026] When the device is in use, when the connecting sleeve 1 is installed on the handrail, the groove 4 of the connecting sleeve 1 is aligned with the handrail for installation. The inclined surface of the stop block 5 is subjected to the force of the handrail to make the stop block 5 compress the stop block spring 7 and slide into the stop block groove 6 until the bottom of the groove 4 is in contact with the handrail. At this time, the stop block 5 slides out under the elastic force of the stop block spring 7 and abuts against the surface of the handrail, thereby installing the connecting sleeve 1 and the handrail, and the contact surfaces with the handrail are the inner wall of the groove 4 and the stop block 5, which are smooth surfaces and in contact with the handrail, which can greatly reduce the friction loss between the handrail and the connecting sleeve 1, and the spraying operation can be carried out. When disassembling, the pressing column 14 is pressed to act on the inclined surface of the connecting rod 12 to move the connecting rod 12. The movement of the connecting rod 12 drives the roller 19 to move and act on the inclined surface of the control groove 10. The roller 19 rolls on the inclined surface of the control groove 10 to make the stop block 5 compress the stop block spring 7 and slide into the block groove 6, thereby making the connecting sleeve 1 disassembled from the handrail, and the operation is convenient.
