When the female plug 2 is inserted into the gateway shell 1, the first push block 11 is pulled outward to pull the inner cylinder 5 outward, then the protrusions 8 are clamped in the clamping grooves 35 inside the inner cylinder 5 by pressing the inclined plate 7, so as to limit the female plug 2, the first push block 11 is released, and the inner cylinder 5 is reset under the action of the first spring 9, so as to tightly insert the female plug 2. Since the first spring 9 will pull the female plug 2 towards the gateway shell 1, the female plug 2 is tightly inserted into the gateway shell 1, the possibility of loosening the female plug 2 is reduced, and when the connecting line 3 is accidentally pulled during the transportation of goods, the female plug 2 can also be prevented from being pulled off. Even if the female plug 2 is pulled off, it can also be automatically reset under the action of the first spring 9, so as to avoid the need for staff to tightly insert the female plug 2. When the female plug 2 is in poor contact after a long time of use, the corresponding electric push rod 12 is controlled to be elongated by an external controller, so as to drive the baffle 13, the inner cylinder 5 and the female plug 2 to move, pull out the female plug 2, then reset the electric push rod 12 to drive the female plug 2 to reset, complete the plug-in and pull-out action of the female plug 2, and avoid the need for staff to operate. In most cases, the problem of poor contact can be solved by plugging and pulling out the female plug 2, so that automatically plugging and pulling out the female plug 2 can save the time of staff.

[0027] The inner cylinder 5 is provided with a limiting block 6 on the outer wall, the limiting block 6 can limit the inner cylinder 5, so that the inner cylinder 5 can only move along the axis direction of the inner cylinder 4 and the outer cylinder 5, so that the female plug 2 can be aligned with the male plug during the process of pulling and inserting, so as to avoid the female plug 2 from being inserted obliquely, and to avoid the female plug 2 or the male plug from being damaged.

The snap ring 17 supports the connecting line 3, which can avoid the connecting line 3 and the female plug 2 from being damaged due to excessive force, thereby increasing the service life of the connecting line 3 and the female plug 2, and avoiding the connecting line 3 from being pulled down to the female plug 2 under the action of gravity, causing the female plug 2 to be loose with the male plug, resulting in poor contact and affecting the normal use of the gateway. When the electric push rod 12 pushes the baffle 13 to move, the horizontal rod 15 and the vertical rod 16 also move with it, the vertical rod 16 drives the snap ring 17 to move through the vertical slot 18 and the clamping rod 19, and the snap ring 17 supports the connecting line 3 when moving, which can avoid the connecting line 3 from being stuck or pulled down to the female plug 2 due to other reasons during the movement of the female plug 2, causing the female plug 2 to be inclined at an angle and unable to be accurately inserted into the male plug, resulting in the failure of the female plug 2 to be inserted.

During installation and disassembly, only the snap ring 17 and the clamping rod 19 need to be taken out of the vertical slot 18, which is simple and convenient to operate.

[0030] As a technical optimization scheme of the present application, the outer wall of the gateway shell 1 is connected with a fixing ring 20, the inner side of the fixing ring 20 is fixedly connected with the rear end outer wall of the gateway shell 1, an annular groove 22 is formed in the top of the fixing ring 20, an arc-shaped block 27 is installed on the outer side of the fixing ring 20, a through groove 28 is formed through the arc-shaped block 27, the fixing ring 20 penetrates through the through groove 28 and is slidably connected with the inner wall of the through groove 28, the second bolt 29 is threadedly connected with the upper part of the arc-shaped block 27, and the bottom of the second bolt 29 abuts against the top of the fixing ring 20. The arc-shaped block 27 is slidably installed on the fixing ring 20, after the second bolt 29 is loosened, the corresponding arc-shaped block 27 can be moved, when the gateway shell 1 needs to be installed at the corner of a wall, the arc-shaped block 27 can be moved by a certain angle along the fixing ring 20, so that the gateway shell 1 is conveniently installed, after the arc-shaped block 27 is moved, the arc-shaped block 27 can be fixed at any moved position on the fixing ring 20 by tightening the second bolt 29, and the operation is simple and convenient; when the gateway shell 1 is fixed on a shelf or there are objects around that can assist in fixing, the arc-shaped block 27 can be rotated by a certain angle, so that the fixing rod of the shelf or other objects that can assist in fixing is located in the gap 31, and then the third bolt 32 is tightened for fixing, so that the fixing mode of the gateway shell 1 is increased, and the gateway shell 1 is fixed more firmly on the basis of being fixed by the vertical plate 34.

[0031] As a technical optimization scheme of the present application, one side of the fixing ring 20 is provided with an arc-shaped ring 21, the fixing ring 20 and the arc-shaped ring 21 form a ring, the arc-shaped ring 21 is located at the front end of the gateway shell 1, the arc-shaped ring 21 is provided with a fixing block 24 at both ends, the fixing block 24 is vertically provided with a circular hole 25, the fixing ring 20 is provided with a fixing groove 23 at both ends, the upper part of the fixing groove 23 is provided with a first bolt 26, and the fixing block 24 can be inserted into the fixing groove 23 and the first bolt 26 can penetrate through the circular hole 25. The arc-shaped ring 21 is connected with the fixing ring 20 through the fixing block 24, the circular hole 25, the first bolt 26 and the fixing groove 23, when a fault occurs in the gateway device, the staff member can unscrew the first bolt 26, so that the arc-shaped ring 21 can be removed, so that the gateway shell 1 can be disassembled, and when the arc-shaped block 27 needs to be disassembled, the arc-shaped ring 21 can be disassembled in the same way, so that the arc-shaped block 27 can be removed, and the operation is simple.

[0032] As a technical optimization scheme of the present application, a sliding groove is horizontally formed in the side of the arc-shaped block 27 away from the gateway shell 1, a winding rod 30 is arranged in the sliding groove, one end of the winding rod 30 is slidably connected with the inner wall of the sliding groove, the other end is provided with a baffle, a second spring 33 is arranged in the sliding groove, one end of the second spring 33 is fixedly connected with the winding rod 30, and the other end is fixedly connected with the inner wall of the sliding groove. There are many goods and shelves in the cold storage, when the goods are carried, the connecting line 3 is easily pulled, the excess connecting line 3 is wound on the winding rod 30, so that the connecting line 3 is in a relatively tight state, the connecting line 3 is avoided to be loosely hung in the air, and the possibility that the staff member touches the connecting line 3 is reduced.

[0033] As a technical optimization scheme of the present application, the arc-shaped block 27 is provided with a notch 31 on both sides in the horizontal direction, a threaded hole is horizontally provided on the side wall of the notch 31, and a third bolt 32 is arranged in the threaded hole. When the connecting line 3 is too long, the connecting line 3 can be wound on the notch 31. Since the arc-shaped block 27 is in a fixed state during use, the connecting line 3 will not be affected when the connecting line 3 is accidentally pulled when there is no need to move the goods. The connecting line 3 is first wound on the notch 31 and then wound on the winding rod 30. When the connecting line 3 is pulled, the winding rod 30 moves, the second spring 33 first buffers, the connecting line 3 wound on the notch 31 does not move, and the female plug 2 is protected from loosening, so that the gateway device runs more stably.

[0034] As a technical optimization scheme of the present application, the fixed ring 20 is fixedly connected with a vertical plate 34, the vertical plate 34 is located at the rear end of the gateway shell 1, and a fixing hole is formed in the vertical plate 34.

[0035] As shown in FIGS. 1-8, during use, first, the gateway shell 1 is installed at a predetermined position on the cold storage. When the wall of the cold storage can be screwed, the gateway shell 1 can be fixed by using the bolt hole on the vertical plate 34. When the wall of the cold storage cannot be screwed, the gateway shell 1 can be hung on the shelf of the cold storage by using the fixed ring 20 and the vertical plate 34, so as to fix the gateway shell 1. The gateway shell 1 is provided with multiple groups of fixed rings 20 and vertical plates 34. The bottommost vertical plate 34 is flush with the bottom of the gateway shell 1, and the stability is increased when the vertical plate 34 is placed on the ground.

[0036] After the gateway shell 1 is installed, the clamping ring 17 is lifted upward, the corresponding two clamping rods 19 are separated, the connecting line 3 and the female plug 2 pass through the clamping ring 17, the clamping rod 19 is inserted into the vertical groove 18, the connecting line 3 is limited, and then the female plug 2 is inserted into the gateway shell 1. Since the clamping ring 17 supports the connecting line 3, the force on the connection between the connecting line 3 and the female plug 2 can be avoided, so as to avoid damage to the connection between the connecting line 3 and the female plug 2, increase the service life of the connecting line 3 and the female plug 2, and avoid the connecting line 3 from pulling the female plug 2 downward under the action of gravity, causing the female plug 2 to be loose from the male plug, resulting in poor contact and affecting the normal use of the gateway.

[0037] After the staff inserts the female plug 2 into the gateway shell 1, the excess connecting line 3 is wound on the winding rod 30, and the gateway device can be normally used.

[0038] When the staff inserts the female plug 2 on the gateway shell 1, the inner cylinder 5 is pulled outwards by pulling the first push block 11 outwards, and then the inclined plate 7 is pressed to make the protrusion 8 clamped in the clamping groove 35 inside the inner cylinder 5, thereby limiting the female plug 2, and then the first push block 11 is released, and the inner cylinder 5 is reset under the action of the first spring 9, thereby tightly inserting the female plug 2. Because the first spring 9 will pull the female plug 2 towards the gateway shell 1, the female plug 2 is tightly inserted on the gateway shell 1, reducing the possibility of the female plug 2 being loosened, and when the connection line 3 is accidentally pulled by the transported goods, the female plug 2 can also be prevented from being loosened. Even if the female plug 2 is pulled, it can also be automatically reset under the action of the first spring 9, avoiding the need for staff to tighten the female plug 2.

[0039] There are many goods and shelves in the cold storage, and when the goods are transported, the connection line 3 is easily pulled. Winding the excess connection line 3 on the winding rod 30 can make the connection line 3 in a relatively tight state, avoiding the connection line 3 hanging in the air in a loose state, reducing the possibility of the staff touching the connection line 3. When the staff accidentally touches and pulls the connection line 3, the winding rod 30 can move in the horizontal direction, and the second spring 33 can buffer, further reducing the possibility of the female plug 2 being loosened, making the gateway device more stable in use.

[0040] When the female plug 2 has a poor contact after a long time of use, the corresponding electric push rod 12 is controlled to extend by the external controller, thereby driving the baffle 13 and the second push block 14 to move away from the gateway shell 1. The inner cylinder 5 drives the inclined plate 7 and the female plug 2 to move with the second push block 14 through the protrusion 8 and the clamping groove 35, thereby pulling out the female plug 2. Then the electric push rod 12 is reset, driving the baffle 13, the second push block 14, the inner cylinder 5, the protrusion 8, the inclined plate 7 and the female plug 2 to reset, completing the plug-in and pull-out action of the female plug 2, avoiding the need for staff to operate. In most cases, the problem of poor contact can be solved by plugging and unplugging the female plug 2, so that automatically plugging and unplugging the female plug 2 can save the staff's time.

[0041] The inner cylinder 5 is provided with a limiting block 6 on the outer wall, which can limit the movement of the inner cylinder 5, so that the inner cylinder 5 can only move along the axis direction of the inner cylinder 4 and the outer cylinder 5, thereby aligning the male plug during the plugging and unplugging process, thereby avoiding the female plug 2 being inserted off-center and causing damage to the female plug 2 or the male plug.

[0042] When the electric push rod 12 pushes the baffle 13 to move, the cross rod 15 and the vertical rod 16 also move with it, the vertical rod 16 drives the clasp 17 to move through the vertical slot 18 and the clamping rod 19, and the clasp 17 supports the connecting line 3 when moving, avoiding the connecting line 3 from being stuck or being pulled down to the female plug 2 due to other reasons, causing the female plug 2 to be inclined at an angle, not being able to be accurately inserted into the male plug, and causing the female plug 2 to fail to be inserted, and even possibly causing the female plug 2 or the male plug to be damaged.

[0043] The clasp 17 is inserted into the vertical slot 18 through the clamping rod 19, and when installing and disassembling, only the clasp 17 and the clamping rod 19 need to be taken out of the vertical slot 18, which is simple and convenient to operate.

[0044] The arc-shaped block 27 is slidably installed on the fixed ring 20, and after the second bolt 29 is loosened, the corresponding arc-shaped block 27 can be moved, when the gateway shell 1 needs to be installed at a corner, the arc-shaped block 27 can be moved by a certain angle along the fixed ring 20, facilitating the installation of the gateway shell 1, and after the arc-shaped block 27 is moved, the arc-shaped block 27 can be fixed at any moved position on the fixed ring 20 by tightening the second bolt 29, which is simple and convenient to operate; when the gateway shell 1 is fixed on a shelf or there are objects around that can assist in fixing, the arc-shaped block 27 can be rotated by a certain angle, so that the fixing rod of the shelf or other objects assisting in fixing is located in the gap 31, and then the third bolt 32 is tightened for fixing, which can increase the fixing mode of the gateway shell 1, and based on the fixing by the vertical plate 34, the gateway shell 1 is fixed more firmly.
