Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a slender hole hard alloy nozzle comprises a nozzle body 1 and a shoulder block 2 wrapped outside the nozzle body 1, wherein a material spraying hole 4 is formed inside the nozzle body 1, a sealing block 5 is arranged above the nozzle body 1, an inverted trapezoidal blocking block 6 is fixedly connected to the lower end face of the sealing block 5 to prevent residual spraying materials inside the nozzle body 1 from flowing out, a cavity 601 is formed in the center of the blocking block 6 to provide a space for the movement of a T-shaped rod 7, meanwhile, the end part of the T-shaped rod 7 is limited, the T-shaped rods 7 are arranged on the two sides of the cavity 601, the end part of the T-shaped rod 7 is fixedly connected with a rubber block 8, the two T-shaped rods 7 are elastically connected through a spring 9, the rubber block 8 is tightly attached to the inverted trapezoidal section 402 of the material spraying hole 4 by the reverse elasticity of the spring 9, so that the sealing block 5 is prevented from being separated from the material spraying hole 4.

Specifically, as shown in fig. 2, the spraying hole 4 includes a direct current section 401 and an inverted trapezoid section 402, and the design of the inverted trapezoid section 402 can effectively increase the spraying range, so that the spraying material can be more uniformly sprayed on the surface of the foreign object.

Specifically, as shown in fig. 2, a filter screen 10 is embedded at the bottom end of the direct current section 401 to filter out impurities in the sprayed material, so as to ensure that the quality of the sprayed material is more uniform.

Specifically, as shown in fig. 3, the rubber block 8 is disposed in an inclined manner, and the inclined angle is equal to the inclined angle of the inverted trapezoidal section 402, so that the rubber block 8 and the inverted trapezoidal section 402 can be tightly attached to each other.

Specifically, as shown in fig. 1, the material of the nozzle body 1 is made of tungsten carbide and cobalt, so that the hardness and the wear resistance of the nozzle body 1 are improved.

Specifically, as shown in fig. 1, an external thread 3 is arranged on the nozzle body 1 and below the shoulder block 2, and can be screwed and locked with the nozzle, so that the nozzle body 1 can be conveniently detached and installed.

The working principle is as follows: when the spray nozzle is used, the external thread 3 of the spray nozzle body 1 is tightly connected with a spray head, spray materials reach the end part of the spray nozzle body 1, impurities in the spray materials are filtered through the filter screen 10, then the spray materials enter the direct-current section 401, enter the inverted trapezoidal section 402 through the direct-current section 401 and then are sprayed out of the inverted trapezoidal section 402 to be sprayed on the surface of a foreign object, and the design of the inverted trapezoidal section 402 can effectively enlarge the spraying range and enable the spray materials to be sprayed on the surface of the foreign object more uniformly; when stopping the spraying, put into spouting material hole 4 with the chock 6, press sealed piece 5, the motion of "T" shape pole 7 to cavity 601 center department, spring 9 is compressed, when sealed piece 5 contacted with nozzle body 1, stop pressing sealed piece 5, spring 9 gives "T" shape pole 7 and the opposite elasticity of direction of motion this moment for the rubber block 8 closely laminates with the trapezoidal section 402 that falls of spouting material hole 4, thereby prevent that sealed piece 5 from breaking away from spouting material hole 4, cause the loss and the air-drying of spouting the material.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
