[0026] 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.

[0027] The frame spray-coated partial protection structure provides two technical solutions:

[0028] like Figure 1-Figure 5 The first embodiment is shown: it includes a frame body 1, and a local protection mechanism for local protection during plastic spraying is provided on the frame body 1, and the local protection mechanism includes:

[0029] The blocking assembly 3 includes an upper semicircular baffle 31 and a lower semicircular baffle 32. The top of the lower semicircular baffle 32 is fixedly connected with two front and rear plug blocks 33. The bottom of the upper semicircular baffle 31 is provided with slots 34 corresponding to the positions of the two plug blocks 33.

[0030] The clamping assembly 4 is provided with two groups, and the two groups of clamping assemblies 4 are respectively staggered and arranged inside the upper semicircular baffle 31 and the lower semicircular baffle 32. The clamping assembly 4 includes a T-shaped frame 41, and the T-shaped frame 41 is fixed on the inner side of the upper semicircular baffle 31. A slide groove 42 is provided at the bottom of the T-shaped frame 41. The inner surface of the slide groove 42 is slidably connected with two front and rear clamping plates 43, and the clamping plates 43 can automatically adapt to the shape of the clamped object. A limiting spring 44 is fixedly connected between the two clamping plates 43, and a plurality of circular grooves 45 are evenly provided on the inner side of the clamping plates 43. The inner walls of the plurality of circular grooves 45 are fixedly connected with connecting springs 46, and the other ends of the plurality of connecting springs 46 are fixedly connected with cylindrical blocks 47.

[0031] The adapter component 5 is arranged on the left and right sides of the upper semicircular baffle 31 and the lower semicircular baffle 32, and is used to adapt to the square rod and the round rod in the frame body 1. The adapter component 5 includes two left and right square grooves 51 and an adapter. The two square grooves 51 are respectively opened on the left and right sides of the upper semicircular baffle 31. The adapter is inserted into the inside of the square groove 51. The adapter consists of an arc groove plate 52 and a square groove plate 53, and is selected and installed according to the specific rod type. The outer shapes of the arc groove plate 52 and the square groove plate 53 are both rectangular structures with the same shape as the square groove 51.

[0032] When the frame body 1 is partially protected, the blocking assembly 3 is installed to the outside of the protection through the clamping assembly 4, so as to facilitate the operation. In addition, the design of multiple cylindrical blocks 47 on the clamping assembly 4 enables the clamping plate 43 to be installed on both the square rod and the round rod on the frame body 1, thereby improving the practicability of the device when in use.

[0033] like Figure 3 and Figure 5 The second embodiment is shown, and its main difference from the first embodiment is that the docking assembly 6 assists in splicing multiple local protection mechanisms, and the docking assembly 6 includes four L-shaped plates 61. The four L-shaped plates 61 are divided into two groups, the upper L-shaped plate 61 is bent in the direction of the top, and the upper two L-shaped plates 61 are fixed on the right side of the upper semicircular baffle 31, the lower L-shaped plate 61 is bent in the direction of the bottom, and the lower two L-shaped plates 61 are fixed on the right side of the lower semicircular baffle 32, and the left sides of the upper semicircular baffle 31 and the lower semicircular baffle 32 are fixedly connected with two front and rear U-shaped plates 62, and the positions of the L-shaped plates 61 and the U-shaped plates 62 correspond to each other.

[0034] When a single local protection mechanism is not enough to provide shielding, multiple local protection mechanisms can be used for protection. When multiple local protection mechanisms are used, they can be quickly spliced ​​together through the coordination of splicing components.

[0035] When in use, an arc-shaped slot plate 52 or a square slot plate 53 is selected according to the shape of the rod at the position where the frame body 1 needs to be protected, and the selected adapter is inserted into the square slot 51, and the upper semicircular baffle 31 and the lower semicircular baffle 32 are directly installed on the position on the frame body 1 that needs to be protected through the clamping assembly 4. During installation, the two clamping plates 43 are placed in from the protection position. When placed in, the two clamping plates 43 are kept away from each other. Then, under the action of the limit spring 44, the two clamping plates 43 are clamped to the protection position, and during clamping, the clamping plates 43 can adapt to the shape of the rod at the clamping position through the action of multiple cylindrical blocks 47. In addition, when a single local protection mechanism cannot cover the entire area that needs to be protected, multiple local protection mechanisms can be used in combination. When splicing, the positions of the L-shaped plate 61 and the U-shaped plate 62 are aligned, so that after the upper semicircular baffle 31 and the lower semicircular baffle 32 are installed, the two adjacent local protection mechanisms can be spliced ​​together without position adjustment.
