The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] Example 1

[0030] like Figure 1-4As shown, a spray sleeve for the muzzle of a paint spray gun includes a sleeve portion 100 matched with the muzzle of the paint spray gun, a tapered tube 200 arranged at the left end of the sleeve portion 100, a recovery portion 300 arranged at the left end of the tapered tube 200, a distance measuring portion 400 arranged on the upper side of the recovery portion 300, and a picture card 500 arranged on the left side of the recovery portion 300 and matched with the recovery portion 300.

[0031] The sleeve portion 100 is composed of a sleeve tube 101 whose diameter is larger than the diameter of the muzzle of the paint spray gun, and a fixing screw 102 arranged in the middle of the sleeve tube 101 and penetrating the side wall of the sleeve tube 101; the number of the fixing screws 102 is four, and the four fixing screws 102 are evenly arranged around the sleeve tube 101.

[0032] When in use, first insert the muzzle of the paint spray gun into the sleeve tube, then respectively screw the four fixing screws so that the ends of the fixing screws are respectively pressed against the four sides of the muzzle, thereby completing the fixation between the product and the muzzle of the paint spray gun.

[0033] The recovery part 300 consists of a recovery pipe 301 with an opening on the right side of the bottom on the left side, a spray port 302 arranged on the bottom of the left side of the recovery pipe 301, a U-shaped groove 303 arranged on the outer wall of the bottom of the left side of the recovery pipe 301, an external discharge port 304 arranged on the outer wall of the bottom of the left side of the recovery pipe 301 and connected to the inside of the recovery pipe 301, and an outer cover 305 arranged on the external discharge port 304 and matched with the external discharge port; the U-shaped groove 303 is arranged around the left, lower and right edges of the spray port 302.

[0034] A plurality of support plates 306 flush with the bottom of the recovery pipe 301 are also provided on the outer wall of the recovery pipe 301 .

[0035] The spray port of the recovery pipe provides a spraying channel for the paint, and the paint sprayed to the area outside the spray port can be effectively recovered by the recovery pipe. After spraying, the outer cover can be opened to pour out the recovered paint and reuse it.

[0036] The right end opening diameter of the conical tube 200 is the same as the diameter of the sleeve tube 101, and the left end opening diameter of the conical tube 200 is the same as the diameter of the recovery tube 301; the right side of the conical tube 200 is fixed to the sleeve tube 101 by welding, and the left side of the conical tube 200 is fixed to the recovery tube 301 by welding.

[0037] The conical tube provides a diffusion space for the paint sprayed from the muzzle of the paint spray gun. Since the paint is sprayed and spreads from point to surface, the conical structure can perfectly meet the needs, that is, it does not affect the normal diffusion of the paint and can effectively reduce the overall volume of the product.

[0038] The picture card 500 matches with the U-shaped card slot 303 , and is composed of a picture card body 501 and a spray pattern 502 arranged on the picture card body 501 and whose position matches the spray port 302 .

[0039] After the image card body 501 is inserted into the U-shaped card slot 303 , the plane position of the upper end portion thereof is equal to or lower than the plane position of the top portion of the recovery tube 301 .

[0040] The chart card is a replaceable structure, which is very convenient to use. The spray pattern on it needs to be adjusted according to specific production needs. When the paint sprayed by the paint spray gun passes through the spray pattern, only part of it can pass through the hollow structure on the spray pattern and finally be sprayed on the target object, and the paint after the spray pattern finally forms the required pattern on the target object. The purpose of the top of the chart card body not exceeding the top of the recovery tube is to avoid the top of the chart card body blocking the rangefinder, thereby better ensuring the normal use of the rangefinder.

[0041] The distance measuring part 400 is composed of a mounting block 401, a distance measuring slot 402 provided on the mounting block 401, two openings 403 provided on the front and rear sides of the distance measuring slot 402, two fixing heads 406 provided on both sides of the mounting block 401 and adjacent to the openings 403, a fixing rope 404 passing through the two openings 403 and having its two ends respectively provided on the two fixing heads 406, and a distance meter 405 provided in the distance measuring slot 402 and pressed under the fixing rope 404.

[0042] The size and shape of the distance measuring slot 402 match the distance measuring device 405 , and the left side of the distance measuring slot 402 is open.

[0043] The function of the rangefinder is to measure the distance between the product and the target. Since the distance between the spray gun muzzle and the spray pattern is fixed, the distance between the product and the target can be adjusted to obtain target patterns of different sizes. In addition, when patterns of basically the same size are required, it is necessary to ensure that the distance between the product and the target is the same when spraying different targets.

[0044] The rangefinder is a laser rangefinder, which is a conventional technology. Its specific use principle and method are well known to those skilled in the art, and will not be described in detail here. In addition, the laser rangefinder used in this embodiment is a Deli DL4168 laser rangefinder.

[0045] It should be noted that all features disclosed in this specification, or steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any manner.

[0046] In addition, the above specific embodiments are exemplary, and those skilled in the art can come up with various solutions inspired by the disclosure of the utility model, and these solutions also belong to the disclosure scope of the utility model and fall within the protection scope of the utility model. Those skilled in the art should understand that the utility model specification and its drawings are illustrative and do not constitute a limitation of the claims.
