[0001] The utility model relates to the technical field of production of heptafluoropropane steel cylinders, in particular to a paint spraying rotating rack for heptafluoropropane steel cylinders. Background Art

[0002] Heptafluoropropane is a clean gas chemical fire extinguishing agent that mainly uses chemical fire extinguishing and also has physical fire extinguishing effects. It is colorless, odorless, low-toxic, non-conductive, does not pollute the protected objects, and will not cause damage to property and precision facilities. In order to facilitate transportation and use, heptafluoropropane is mostly stored under pressure in cylinders. In the production process of heptafluoropropane cylinders, in order to improve the anti-oxidation performance of the surface of heptafluoropropane cylinders, it is necessary to spray paint on the outer surface of the cylinder after production is completed.

[0003] The existing painting process generally involves hanging the heptafluoropropane cylinder and then painting it. However, since the heptafluoropropane cylinder is a cylindrical bottle body, the operation process of hanging it is relatively cumbersome, which is not conducive to the actual production of the enterprise. Therefore, a painting rotating rack for heptafluoropropane cylinders is proposed to solve the above problem. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] In the embodiment, Figure 1 and 2 Provided is a paint spraying rotating stand for a heptafluoropropane cylinder, comprising a base 1, a rodless cylinder 2 is fixedly connected to the top of the base 1, a mounting seat 3 is fixedly connected to the top of the moving part of the rodless cylinder 2, a reduction motor 4 is fixedly connected to the mounting seat 3, and a fixing component 5 for fixing the heptafluoropropane cylinder is fixedly connected to the output end of the reduction motor 4;

[0020] The fixing assembly 5 includes a fixing sleeve 51, and the fixing sleeve 51 is fixedly connected to the outer side of the output end of the reduction motor 4. A mounting groove 52 is provided at the front end of the fixing sleeve 51, and a plurality of connecting holes 53 connected to the mounting groove 52 are provided on the cylindrical side wall of the fixing sleeve 51. Four fixing blocks 54 are fixedly connected to the inner side of the mounting groove 52, and the four fixing blocks 54 are fixedly connected to strong springs 55 whose number is equal to one-fourth of the number of connecting holes 53. The other ends of the strong springs 55 are fixedly connected to sliding rods 56, and the sliding rods 56 are respectively slidably connected to the inner sides of the connecting holes 53. Friction blocks 57 are fixedly connected to the sliding rods 56. The strong springs 55 are in a compressed state and can be further compressed.

[0021] Through the above arrangement, before using this device, the base 1 needs to be fixed on the workbench, firstly, the heptafluoropropane cylinder is placed horizontally and lifted to the front of the fixing sleeve 51, and the heptafluoropropane cylinder is moved along the outer sides of the plurality of friction blocks 57 until the plurality of friction blocks 57 are all entered into the heptafluoropropane cylinder (during this process, the plurality of strong springs 55 will all shrink, and the plurality of slide bars 56 will respectively move along the inner sides of the plurality of connecting holes 53 toward the center line of the fixing sleeve 51). When the plurality of friction blocks 57 are all entered into the heptafluoropropane cylinder, the plurality of strong springs 55 will gradually extend until the plurality of friction blocks 57 are pushed to the heptafluoropropane cylinder. The inner wall of the heptafluoropropane cylinder is in contact with each other, and the heptafluoropropane cylinder is fixed by the friction between several friction blocks 57 and the inner wall of the heptafluoropropane cylinder. Then, the rodless cylinder 2 is used to move the moving parts of the rodless cylinder 2 and the mounting seat 3, the reduction motor 4 and the heptafluoropropane cylinder forward, and then the heptafluoropropane cylinder is sprayed. During the spraying process, the reduction motor 4 is started to slowly rotate the heptafluoropropane cylinder to spray the outer surface of the heptafluoropropane cylinder. It should be noted that only eight friction blocks 57 are drawn in the figure. In actual use, the number of friction blocks 57 is greater than forty, so as to ensure that the heptafluoropropane cylinder is fixed.

[0022] Reference Figure 1 and 2 , wherein the surface of the friction block 57 in contact with the inner cavity of the heptafluoropropane cylinder is a curved surface adapted to the inner cavity of the heptafluoropropane cylinder;

[0023] Through the above structural setting, when the surface of the friction block 57 in contact with the inner cavity of the heptafluoropropane cylinder is an arc surface adapted to the inner cavity of the heptafluoropropane cylinder, the contact surface of the friction block 57 and the inner cavity of the heptafluoropropane cylinder is larger, the friction force is greater, and the fixing effect is better.
