[0004] In order to facilitate movement, existing replacement devices on the market are generally equipped with wheels at the bottom. However, when the replacement device is in operation and does not need to be moved, the stability of the replacement device is poor and it is easily moved by external influences. At the same time, the replacement device needs to be used with a hose. After using the replacement device, the hose is generally wrapped around the storage column. However, due to the tension of the hose itself, the hose may loosen and fall from the storage column, which may cause damage to the connector on the hose. In order to solve the above problem, an embodiment of the present application provides a nitrogen replacement device. By pressing the two rectangular plates on the fixed block, the rectangular plate drives the plug column to move out of slot two, the support rod will slide downward, and the rectangular plate will be released. Under the action of spring one, the rectangular plate will drive the plug column to be inserted into slot one, and the support rod can support one side of the replacement device body, thereby improving the stability of the replacement device body during operation. At the same time, by pulling the sliding plate upward, the sliding plate squeezes spring two upward, wrapping the hose around the cylinder, and releasing the sliding plate. The sliding plate cooperates with the cylinder to squeeze the hose under the action of spring two to prevent the hose from falling from the cylinder.

[0005] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0006] A nitrogen replacement device, comprising:

[0007] The replacement device body has walking wheels installed at the bottom of the replacement device body, and fixed blocks are fixed on both sides of the replacement device body. Two support rods are slid on the two fixed blocks, and the fixed blocks are provided with a limiting mechanism capable of limiting the two support rods;

[0008] A fixing plate is fixed on one side of the replacement device body, a cylinder is fixed on the fixing plate, and a clamping mechanism capable of clamping the hose wound on the cylinder is provided on the fixing plate.

[0009] In one possible implementation, two guide holes are provided on the fixed block, and the two support rods slide inside the two guide holes respectively. A connecting plate is fixed on the top of the two support rods. The support rods can support the replacement device body to improve the stability of the replacement device body. At the same time, the connecting plate can ensure that the two support rods move at the same time and are located on the same horizontal plane.

[0010] In one possible implementation, the limiting mechanism includes two rectangular blocks fixed on the top of the fixed block, and the two rectangular blocks are each provided with a guide hole 2, and the two guide holes 2 are each provided with a sliding column, and the two columns are fixed with a rectangular plate at one end close to each other, and a spring 1 is provided between the two rectangular plates, and the two ends of the spring 1 are respectively fixed to the two rectangular plates, and the support rod is provided with a slot 1 and a slot 2 on the side facing the column, and the spring 1 is in a compressed state. The spring 1 drives the column through the rectangular block through the rectangular plate and inserts into slot 1 or slot 2, so as to quickly limit the support rod, thereby adjusting the height of the bottom of the support rod.

[0011] In one possible implementation, the clamping mechanism includes a sliding groove provided on a fixed plate, a sliding plate sliding inside the sliding groove, a second spring provided inside the sliding groove at the top of the sliding plate, and the second spring is in a compressed state. The second spring will drive the sliding plate to slide downward in the sliding groove, so that the sliding plate cooperates with the cylinder to clamp the hose to prevent the hose from falling off the cylinder.

[0012] In one possible implementation, a baffle is fixed to one end of the cylinder away from the connecting plate, and a slot is provided on the baffle to accommodate the sliding plate, so that the sliding plate can be closer to the hose and the clamping force of the sliding plate and the cylinder on the hose is improved.

[0013] In one possible implementation, a guide column is provided inside the sliding groove, the guide column passes through the sliding plate, both ends of the guide column are fixedly connected to the inner wall of the rectangular groove, and the second spring is set on the outside of the guide column. The guide column prevents the sliding plate and the second spring from falling off from the sliding groove, thereby improving the stability of the sliding plate when moving.

[0014] In a possible implementation, both the first slot and the second slot can accommodate the insertion of the pin, and the first slot and the second slot are the same size, which facilitates limiting the support rod.

[0015] In one possible implementation, the column is inserted into slot one, and the height of the bottom of the support rod is lower than the height of the bottom of the walking wheel. At this time, the replacement device body can be supported to prevent the walking wheel at the bottom of the replacement device body from contacting the ground and causing the replacement device body to move. The column is inserted into slot two, and the height of the bottom of the support rod is higher than the height of the bottom of the walking wheel. At this time, the walking wheel contacts the ground, and the support rod does not contact the ground, which facilitates the movement of the replacement device body.

[0016] In summary, the present invention has at least one of the following beneficial technical effects:

[0017] 1. By pressing the two rectangular plates on the fixed block, the two rectangular plates move toward each other, squeezing spring one, and at the same time, the rectangular plates drive the plug-in column to move out of slot two, the support rod will slide downward, loosen the rectangular plate, and under the action of spring one, the rectangular plate will drive the plug-in column to insert into slot one, and the support rod can support one side of the replacement device body, thereby improving the stability of the replacement device body during operation.

[0018] 2. Pull the sliding plate upward, and the sliding plate will squeeze the spring 2 upward, wrapping the hose around the cylinder.

[0024] The following will be combined with the drawings in the present invention to clearly and completely describe the technical solution of the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The instrument placement rack involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] This embodiment introduces a specific structure of a nitrogen replacement device. Figures 1-4 As shown, a nitrogen replacement device includes:

[0026] The replacement device body 1 has a walking wheel 5 installed at the bottom of the replacement device body 1. Fixed blocks 3 are fixed on both sides of the replacement device body 1. Two support rods 4 are slid on the two fixed blocks 3. The fixed blocks 3 are provided with a limiting mechanism that can limit the two support rods 4.

[0027] The fixing plate 13 is fixed to one side of the replacement device body 1 . A cylinder 15 is fixed on the fixing plate 13 . The fixing plate 13 is provided with a clamping mechanism capable of clamping the hose wound on the cylinder 15 .

[0028] In order to facilitate movement, replacement equipment on the market is generally equipped with wheels at the bottom. However, when it is in operation and does not need to be moved, the stability of the replacement equipment is poor and it is easily moved by external influences. Two guide holes 6 are provided on the fixed block 3, and the two support rods 4 slide inside the two guide holes 6 respectively. A connecting plate 2 is fixed on the top of the two support rods 4. The support rods 4 can support the replacement equipment body 1 to improve the stability of the replacement equipment body 1. At the same time, the connecting plate 2 can ensure that the two support rods 4 move at the same time and are located on the same horizontal plane.

[0029] It is worth noting that the limiting mechanism includes two rectangular blocks 9 fixed on the top of the fixed block 3, and the two rectangular blocks 9 are each provided with a guide hole 21, and the two guide holes 21 are each slid with a plug 21, and the two plugs 21 are fixed with a rectangular plate 11 at one end close to each other, and a spring 10 is provided between the two rectangular plates 11, and the two ends of the spring 10 are respectively fixed to the two rectangular plates 11, and the support rod 4 is provided with a slot 1 8 and a slot 2 7 on the side facing the plug 21, and the spring 10 is in a compressed state. The spring 10 drives the plug 21 through the rectangular block 9 through the rectangular plate 11 and inserts it into the slot 1 8 or the slot 2 7, so as to quickly limit the support rod 4, thereby adjusting the height of the bottom of the support rod 4.

[0030] The replacement device needs to be used with a hose. After using the replacement device, the hose will generally be wrapped around the storage column. However, due to the tension of the hose itself, the hose will loosen and fall from the storage column, which may cause damage to the connector on the hose. The clamping mechanism includes a sliding groove 18 provided on the fixed plate 13, and a sliding plate 19 slides inside the sliding groove 18. A spring 2 17 is provided at the top of the sliding plate 19 inside the sliding groove 18. The spring 2 17 is in a compressed state. The spring 2 17 will drive the sliding plate 19 to slide downward in the sliding groove 18, so that the sliding plate 19 cooperates with the cylinder 15 to clamp the hose to prevent the hose from falling from the cylinder 15.

[0031] In addition, a baffle 14 is fixed to one end of the cylinder 15 away from the connecting plate 2. A notch 20 is provided on the baffle 14. The notch 20 can accommodate the sliding plate 19, so that the sliding plate 19 can be closer to the hose, thereby increasing the clamping force of the sliding plate 19 and the cylinder 15 on the hose.

[0032] What's more, a guide column 16 is provided inside the sliding groove 18, and the guide column 16 passes through the sliding plate 19. Both ends of the guide column 16 are fixedly connected to the inner wall of the rectangular groove. The second spring 17 is sleeved on the outside of the guide column 16. The guide column 16 prevents the sliding plate 19 and the second spring 17 from falling off from the sliding groove 18, thereby improving the stability of the sliding plate 19 when moving.

[0033] Furthermore, both slot one 8 and slot two 7 can accommodate the insertion of the pin 21 , and slot one 8 and slot two 7 are the same size, which facilitates limiting the support rod 4 .

[0034] It is worth noting that the column 21 is inserted into the slot 1 8, and the height of the bottom of the support rod 4 is lower than the height of the bottom of the walking wheel 5. At this time, the replacement device body 1 can be supported to prevent the walking wheel 5 at the bottom of the replacement device body 1 from contacting the ground and causing the replacement device body 1 to move. The column 21 is inserted into the slot 2 7, and the height of the bottom of the support rod 4 is higher than the height of the bottom of the walking wheel 5. At this time, the walking wheel 5 contacts the ground, and the support rod 4 does not contact the ground, which facilitates the movement of the replacement device body 1.

[0035] Among them, the model of the replacement equipment body 1 is PCL nitrogen replacement machine.

[0036] When the staff needs to use the replacement device body 1, first lift one side of the replacement device body 1 and press the two rectangular plates 11 on the fixed block 3 (the side of the replacement device body 1 that is lifted). The two rectangular plates 11 move toward each other and squeeze the spring 10. At the same time, the rectangular plate 11 drives the plug 21 to move out of the slot 2 7. At this time, due to the gravity of the support rod 4, the support rod 4 will slide downward. After the sliding is completed, release the rectangular plate 11. Under the action of the spring 10, the rectangular plate 11 will drive the plug 21 to insert into the slot 1 8. At this time, lift one side of the replacement device body 1 and put it down. The support rod 4 can support one side of the replacement device body 1. Similarly, the other side of the replacement device body 1 is also done. In this way, the support function of the replacement device body 1 is completed, and the stability of the replacement device body 1 during operation is improved. The reverse operation can reset the support column, which is convenient for moving the replacement device body 1.

[0037] After using the replacement device body 1, pull the sliding plate 19 upward, the sliding plate 19 squeezes the spring 2 17 upward, and the hose is wrapped around the cylinder 15. Loosen the sliding plate 19, and the sliding plate 19 cooperates with the cylinder 15 under the action of the spring 2 17 to squeeze the hose to prevent the hose from falling off the cylinder 15.

[0038] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
