[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] This utility model provides, for example Figures 1-6 The installation structure of an LNG supply system accessory shown includes a support frame 1 fixed on a gas cylinder 2. A vaporizer 3 and a buffer tank 7 are provided on the front top of the support frame 1. A placement mechanism 4 is provided on the front of the support frame 1 to facilitate the disassembly and installation of the vaporizer 3 and the buffer tank 7.

[0030] like Figure 3 As shown, the placement mechanism 4 includes a placement frame 401 located on the front side of the support frame 1. Two first placement slots 402 are opened on both sides inside the placement frame 401. Each first placement slot 402 is movably connected to a bidirectional threaded rod 403 through a bearing. Both ends of the bidirectional threaded rod 403 are threadedly connected to a limiting plate 404. The front side of the limiting plate 404 passes through the placement frame 401 and extends out of the front side of the placement frame 401. A fixing plate 405 is fixedly provided on the front side of the limiting plate 404. A booster 5 is fixedly provided on the front side of the placement frame 401.

[0031] like Figure 3 As shown, the two bidirectional threaded rods 403 have their ends far apart, both passing through the placement frame 401 and extending out of one side of the placement frame 401. The two bidirectional threaded rods 403 on the same side are both provided with pulleys 406. The two pulleys 406 are fitted with the same belt 407. The end of the bidirectional threaded rod 403 extending out of the placement frame 401 is fixedly provided with a first handle 408.

[0032] When the vaporizer 3 and buffer tank 7 are damaged and need to be removed, turn the first handle 408. The first handle 408 drives the two-way threaded rods 403 to rotate. The two-way threaded rods 403 rotate simultaneously under the action of the pulley 406 and the belt 407. The rotation of the two-way threaded rods 403 drives the two limiting plates 404 to move. By using the two limiting plates 404, the two fixing plates 405 are moved away from both sides of the vaporizer 3 or buffer tank 7, so that the vaporizer 3 and buffer tank 7 can be removed from the placement rack 401 for replacement, thereby extending the service life of this utility model.

[0033] As shown in Figure 4 , the top rear side of the support frame 1 is provided with a fixing mechanism 6 for fixing the support frame 1 on the gas cylinder 2, the fixing mechanism 6 comprises two second placing grooves 601 respectively arranged on the two sides of the inside of the support frame 1, each of the second placing grooves 601 is movably connected with a rotating shaft 602 through a bearing, the two ends of the rotating shaft 602 are provided with limiting rollers 603, the outer sides of the two limiting rollers 603 on one side are both wound with a bandage 604, and one end of the bandage 604 is wound on the outer side of the limiting roller 603 on the other side;

[0034] As shown in Figure 4 , the two ends of the rotating shaft 602 on one side are both fixedly provided with a first connecting plate 605, the far sides of the two first connecting plates 605 are both provided with a coiled spring 606, one end of the coiled spring 606 away from the first connecting plate 605 is fixedly connected with the inside of the support frame 1, and the top end of the rotating shaft 602 on one side penetrates through the support frame 1 and extends out of the top of the support frame 1, and the top end of the rotating shaft 602 extending out of the top of the support frame 1 is fixedly provided with a second handle 607;

[0035] The two bandages 604 are sleeved on the outside of the gas cylinder 2, then the second handle 607 is rotated, the second handle 607 drives the rotating shaft 602 on one side to rotate, the rotating shaft 602 drives the limiting roller 603 to rotate, and the rotation of the limiting roller 603 can stretch the bandage 604, so that the bandage 604 is bound on the outside of the gas cylinder 2, and then the support frame 1 can be fixed on the gas cylinder 2.

[0036] As shown in Figure 5 , 6 , the top end of the rotating shaft 602 extending out of the top of the support frame 1 penetrates through a supporting plate 608, a plurality of plug-in holes 609 are arranged on the supporting plate 608, two mounting holes 610 are arranged on the top of the support frame 1, two connecting rods 612 are plugged into the two mounting holes 610, a second connecting plate 613 is fixedly arranged at the top ends of the two connecting rods 612, a third handle 614 is fixedly arranged on the top of the second connecting plate 613, a limiting groove 611 is arranged on the top of the support frame 1, a spring 615 is fixedly arranged in the limiting groove 611, and the top end of the spring 615 is fixedly connected with the bottom of the second connecting plate 613;

[0037] After the bandage 604 is contracted, the third handle 614 is pulled, the third handle 614 drives the connecting rod 612 to move, the connecting rod 612 is plugged into the mounting hole 610 through the plug-in hole 609 on the supporting plate 608, the spring 615 at the bottom of the second connecting plate 613 utilizes the elasticity of itself to make the connecting rod 612 tightly plugged into the plug-in hole 609 and the mounting hole 610, so that the rotating shaft 602 can be fixed, and the rotating shaft 602 is prevented from rotating.

[0038] When the coil spring 606 no longer receives the pulling force, the coil spring 606 drives the rotating shaft 602 to rotate under the action of its own elasticity, the 602 drives the 603 to rotate, and the 603 can wind the 604 outside the 603, facilitating the installation next time.

[0039] The above only describes some exemplary embodiments of the present application by way of illustration, without doubt, for ordinary skilled in the art, without departing from the spirit and scope of the present application, the described embodiments can be modified in various ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the present application.
