DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1-4 , the present utility model provides the following embodiments:

[0029] A hoop tightening device for fixing a hydrogen storage tank, comprising: a fixed frame, a cushion block 2, a fixed rear clamping frame 3, a hoop band 4 and a locking member 5. The cushion block 2 is arranged at the bottom of the fixed frame, and the fixed rear clamping frame 3 is vertically installed on the inner side in the vertical direction of the fixed frame. Two hoop bands 4 are arranged on the front side of each fixed rear clamping frame 3. The two hoop bands 4 on the same snap ring 31 are locked by the locking member 5 to realize the hoop tightening and fixing of the middle part of the circumference of the hydrogen storage tank 100 and the support and fixing of the bottom, so that the hydrogen storage tank 100 is fixed on the fixed frame, with a simple and stable structure, convenient operation and firm fixing effect.

[0030] The fixing frame includes a front base frame 11 and a vertical frame 13. The vertical frame 13 is located at the rear of the front base frame 11 and can be connected by welding. The two are kept vertical, and the front base frame 11 can be directly placed on the ground.

[0031] The cushion block 2 is installed on the top of the front chassis 11. The cushion block 2 is used to support the bottom of the hydrogen storage tank 100. The cushion block 2 includes a metal bottom block 22 at the bottom and a rubber cushion layer 23 arranged on the upper part of the metal bottom block 22. The metal bottom block 22 can be made of an iron block or a steel block, so as to ensure the overall strength of the cushion block 2, and contact with the bottom of the hydrogen storage tank 100 through the rubber cushion layer to avoid damage.

[0032] A plurality of fixed rear brackets 3 are distributed up and down on the inner side of the cushion block 2. The fixed rear bracket 3 includes a clamping ring 31. The fixed rear bracket 3 is a frame structure with an opening at the front end. The clamping ring 31 can be arranged in the opening. The clamping ring 31 can be connected by welding. The circumferential wall of the hydrogen storage tank 100 fits with the inner wall of the clamping ring 31.

[0033] The bands 4 are rotatably mounted at both ends of the clamp ring 31. The two bands 4 are clamped around the outer wall of the hydrogen storage tank 100 and then locked by the locking member 5. Figure 1 , Figure 2 and Figure 3 After the two hoops 4 are butted together, the locking member 5 is operated to fix the body of the hydrogen storage tank 100 . The operation is simple and the fixation is reliable.

[0034] Two supporting beams are arranged in parallel on the front chassis 11, and a plurality of positioning holes 14 are arranged on the supporting beams at intervals along the length direction thereof. Positioning rods are provided at the bottom of both ends of the cushion block 2, and the cushion block 2 is positioned by plugging the positioning rods with the positioning holes 14 at corresponding positions. In addition, the position of the cushion block 2 can be conveniently adjusted as needed during actual use.

[0035] In some embodiments, a rubber bushing 6 is provided inside the band 4, and the outer side of the rubber bushing 6 is turned outward to wrap around the side edge of the band 4. When the band 4 is locked, the rubber bushing 6 is attached to the side of the hydrogen storage tank 100 to prevent the band 4 from directly contacting the hydrogen storage tank 100 and causing the surface of the hydrogen storage tank 100 to be scratched by the band 4. In addition, the outer side of the rubber bushing 6 is turned outward to wrap around the side edge of the band 4 to effectively prevent the rubber bushing 6 from falling off the band 4 and prevent the edge of the band 4 from cutting the staff. The band 4 is preferably made of steel.

[0036] As a further improvement of the present invention, the stand 13 is fixedly mounted at the rear of the front chassis 11, the rear side of the stand 13 is fixedly mounted with the rear chassis 12, and the stand 13 and the front chassis 11, and the stand 13 and the rear chassis 12 are respectively welded with reinforcement braces. Figure 1, specifically, after designing the rear chassis 12, the supporting area can be increased to ensure the supporting effect and prevent backward tipping; the reinforcing diagonal braces can reinforce the front chassis 11 and the rear chassis 12 at the bottom of the vertical frame 13.

[0037] As a further improvement of the present utility model, an arc-shaped groove 21 is provided on the cushion block 2. There are two cushion blocks 2, and a notch groove for avoiding the bottom interface of the hydrogen storage tank 100 is formed between the two arc-shaped grooves 21. Figure 1 , specifically, the two cushion blocks 2 are placed in parallel on the crossbar on the top surface of the front chassis 11, with a notch in the middle, which can be used as an avoidance and protection space. The designed arc-shaped groove 21 makes the cushion block 2 fit more closely to the bottom of the hydrogen storage tank 100, so as to improve the supporting effect. In addition, the design of the arc-shaped groove 21 also facilitates the removal of the hydrogen storage tank 100 and makes the disassembly and assembly of the hydrogen storage tank 100 more convenient.

[0038] As a further improvement of the present utility model, a snap ring 31 is arranged in the opening on the front surface of the fixed rear bracket 3. A positioning pin 32 is also arranged in the inner cavity of the fixed rear bracket 3. A fixing sleeve 41 is arranged at the tail of the hoop band 4, and the fixing sleeve 41 is sleeved on the positioning pin 32, so that the hoop band 4 can be rotatably installed on the snap ring 31. The cooperation of the positioning pin 32 and the fixing sleeve 41 determines the position of one end of the hoop band 4 and does not affect the hoop operation of the hoop band 4.

[0039] As a further improvement of the present utility model, a connecting sleeve 42 is arranged at the front end of the hoop band 4. The connecting sleeve 42 is used to fix the two parts of the locking member 5. Generally speaking, the two parts of the locking member 5 are separated and are fastened by inserting and then locked. A through hole is opened on the connecting sleeve 42 to facilitate the insertion and docking of the components of the locking member 5.

[0040] As a further improvement of the present utility model, the locking member 5 includes a fixed lock block 52, a movable lock block 54 and a nut 55. The fixed lock block 52 is installed in one connecting sleeve 42. A threaded insertion rod 51 is fixedly installed on one side of the fixed lock block 52. The threaded insertion rod 51 passes through the connecting sleeve 42. The movable lock block 54 is installed in the other connecting sleeve 42. A movable sleeve 53 is installed on the outer wall of the movable lock block 54. The threaded insertion rod 51 passes through the movable lock block 54 and the movable sleeve 53 and is threadedly connected to the nut 55. Figure 4 , specifically, the threaded insertion rod 51 passes through the movable lock block 54 and the movable sleeve 53, and then is threadedly connected to the tail end of the threaded insertion rod 51 through the nut 55 to achieve locking. By rotating the nut 55, the movable sleeve 53 can be driven to move to adjust the locking degree.

[0041] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
