[0022] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] like Figures 1 to 3As shown, a cable cabinet external plugger includes a plugging tube 1 and a sleeve tube 2. The sleeve tube 2 is provided with a slot 5 on the end surface close to one end of the incoming pipe, and the incoming pipe is inserted into the slot 5. The sleeve tube 2 is provided with a mounting groove 6 connected to the slot 5 on the side surface away from the incoming pipe. A pressing mechanism 7 is installed in the mounting groove 6. The pressing mechanism 7 includes a trigger member 71, a compression spring 72, a pressure plate 73, a transmission assembly 74 and a tension spring 75. The trigger member 71 is slidably connected to the inner wall of the mounting groove 6. The two ends of the plugging tube 1 are respectively provided with a circular pipe port and a wiring port. On the outer circumferential surface of one end of the wiring port of the plugging tube 1 and the sleeve tube 2 is provided with a fastener 3 on the outer circumferential surface of one end away from the pipe port. The wiring port of the blocking pipe 1 is sleeved on the end of the sleeve pipe 2 away from the inlet pipe. The two ends of the compression spring 72 are respectively connected to the inner wall of the mounting groove 6 and the side surface of the trigger member 71 located in the mounting groove 6. The transmission assembly 74 is connected to the surface of the trigger member 71 and is located inside the mounting groove 6. The pressure plate 73 is connected to the surface of the transmission assembly 74. The two ends of the tension spring 75 are respectively connected to the inner wall of the mounting groove 6 and the side surface of the pressure plate 73 located in the mounting groove 6. The pressure plate 73 is slidably connected to the inner wall of the mounting groove 6 to compress the inner wall of the inlet pipe.

[0024] It should be noted that the portion of the trigger member 71 located outside the mounting groove 6 is a rectangular parallelepiped.

[0025] It should be further explained that the shape of the pressing plate 73 fits the inner wall of the inlet pipe and is in the shape of an arc plate.

[0026] like Figure 4 As shown in the partial structure, the transmission assembly 74 includes an inclined block 741, a transmission block 742 and a matching block 743. The inclined block 741 is located in the installation groove 6 and is connected to the surface of the trigger member 71. The transmission block 742 is slidably connected to the inner wall of the installation groove 6. Pressing the trigger member 71 can drive the inclined block 741 and push the transmission block 742. The matching block 743 is located in the installation groove 6 and is connected to the surface of the pressure plate 73. Moving the transmission block 742 can drive the matching block 743 and push the pressure plate 73 into the slot 5.

[0027] It should be noted that when the trigger member 71 is pressed, the inclined block 741 is moved together, the inclined block 741 pushes the transmission block 742, and the transmission block 742 pushes the matching block 743, so that the pressure plate 73 presses against the inner wall of the incoming pipe, thereby increasing the firmness and stability of the connection between the incoming pipe and the sleeve pipe 2.

[0028] It should be further explained that the surfaces where the inclined block 741 and the transmission block 742 contact each other are both inclined surfaces, and the surfaces where the transmission block 742 and the matching block 743 contact each other are both inclined surfaces.

[0029] Furthermore, an inclined slot 8 is provided at one end of the line inlet of the blocking tube 1 , and the trigger member 71 is located inside the inclined slot 8 . The inclined slot 8 cooperates with the trigger member 71 to drive the transmission block 742 to move.

[0030] In actual use, the sleeve tube 2 is sleeved onto the wiring tube connected to the cable cabinet, so that one end of the wiring tube is inserted into the slot 5, and then the sleeve tube 2 is fastened to the wiring tube using the fastener 3. The side of the inclined groove 8 away from the sleeve tube 2 is inclined, and then the blocking tube 1 is sleeved on the sleeve tube 2. When the trigger member 71 is inserted into the inclined groove 8, the inclined surface of the inclined groove 8 contacts the trigger member 71, causing the trigger member 71 to move into the installation groove 6. When the blocking tube 1 is completely sleeved on the surface of the sleeve tube 2, the trigger member 71 should be completely located in the installation groove 6 and abut against the inner wall of the blocking tube 1.

[0031] like Figure 5 and Figure 6 In the partial structure shown, a clamping piece 9 is provided on the surface of the sleeve pipe 2 close to one end of the blocking pipe 1 , and the clamping piece 9 is used to connect the sleeve pipe 2 and the blocking pipe 1 .

[0032] Furthermore, the clamping member 9 includes a spring 91 and a clamping block 92. The clamping block 92 is inclined on the side close to the sealing tube 1. A clamping groove 93 is provided on the inner wall of the sealing tube 1 close to the pipe port. A groove 94 is provided on the surface of the sleeve pipe 2 close to the end of the sealing tube 1. The clamping block 92 is slidably connected to the inner wall of the groove 94 and extends into the groove 93.

[0033] Furthermore, a pressing assembly 4 is provided on the blocking tube 1 , and the pressing assembly 4 moves the clamping block 92 out of the clamping slot 93 .

[0034] Furthermore, the pressing assembly 4 includes a ring 41 and a pressing block 42. The ring 41 is sleeved on the surface of the sealing tube 1 near one end of the pipe port. The pressing block 42 is slidably connected in the slot 93. One end face of the pressing block 42 extends from the slot 93 to the outside of the sealing tube 1 and is connected to the inner wall of the ring 41. Rotating the ring 41 drives the pressing block 42 to rotate, so that the clamping block 92 moves into the groove 94.

[0035] It should be noted that the surface of the clamping block 92 close to the pressing block 42 is an inclined surface.

[0036] In actual use, when the blocking tube 1 is sleeved on the sleeve tube 2, the edge of the blocking tube 1 at one end of the pipe port contacts the inclined surface of the clamping block 92 close to the blocking tube 1, so that the clamping block 92 is moved into the groove 94 until the clamping groove 93 corresponds to the clamping block 92. Due to the force of spring 1 91, the clamping block 92 moves into the clamping groove 93, thereby connecting the sleeve tube 2 and the blocking tube 1. When the blocking tube 1 needs to be removed from the sleeve tube 2, the ring 41 can be rotated to drive the pressing block 42 to rotate together. The pressing block 42 contacts the inclined surface of the pressing block 42, so that the pressing block 42 is completely moved into the groove 94, and then the blocking tube 1 can be removed.

[0037] Furthermore, the fastener 3 is a clamp.

[0038] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
