Description

Technical Field

[0001] The utility model relates to the field of denture processing, in particular to a sandblasting device for denture processing. Background Art

[0002] In the field of denture processing, sandblasting is a commonly used denture surface treatment method. At present, traditional denture processing sandblasting devices have some shortcomings.

[0003] On the one hand, traditional sandblasting equipment lacks adequate hand protection during operation. Operators' hands are directly exposed to the processing environment during denture sandblasting, making them vulnerable to damage from the blasting material and posing a safety hazard. Furthermore, removing dentures for processing is not convenient, hindering processing efficiency.

[0004] On the other hand, the sandblasting guns of traditional sandblasting equipment are relatively simple in function. They can usually only operate within a single sandblasting range and cannot be fine-tuned to meet different processing requirements. It is difficult to meet the processing requirements of different parts and different precision requirements in denture processing.

[0005] In addition, the stability of component connections in traditional sandblasting equipment needs to be improved. During the processing, problems such as loose connections may occur, affecting the sandblasting effect and processing quality. Utility Model Content

[0008] In one embodiment, a plurality of telescopic holes are opened inside the inner wall of the cylindrical position-limiting access hole, and the plurality of telescopic holes are symmetrically arranged at the center and located outside the position-limiting sleeve.

[0009] In one embodiment, a telescopic seat is slidably connected to the interior of the telescopic hole near one end of the limiting sleeve, and the telescopic seat is clamped inside the telescopic hole. A limiting ball is rollingly connected to the interior of the telescopic seat near the center of one end of the limiting sleeve.

[0010] In one embodiment, the limiting ball protrudes from the outside of the telescopic seat at one end close to the limiting sleeve and protrudes from the inside of the limiting access hole, and a limiting spring is provided at one end of the telescopic seat away from the limiting sleeve.

[0011] In one embodiment, the telescopic seat is elastically connected to the inside of the telescopic hole through a limiting spring, and the limiting ball is clamped to the inside of the limiting sleeve through a limiting snap ring groove.

[0012] In one embodiment, the limiting snap ring groove is provided inside the cylindrical outer wall of the limiting sleeve, and the limiting ball is rollingly connected inside the limiting snap ring groove.

[0013] In one embodiment, the lower end of the sandblasting gun is fixedly connected to a limit slider, the lower end of the limit slider is externally sleeved with a swivel slide, and the limit slider is slidably connected to the inner portion of the upper end of the swivel slide.

A plurality of hemispherical locking holes are provided inside the inner walls of the front and rear ends of the swivel slide, and the locking clamp is clamped inside the locking holes.

[0017] Beneficial effects:

[0018] 1. Convenient operation and protective design: A sealed cover is set at the top of the processing room. The hand passes through the limit sleeve and is inserted into the glove, so that the operation can be carried out in a sealed environment, which protects the hands and facilitates the removal and processing of dentures, improving the convenience and safety of operation.

[0019] 2. Fixed design of the limit sleeve: After the limit sleeve is inserted into the limit pick-up and release hole, the limit ball is engaged with the limit snap ring groove on the outside of the limit sleeve through the cooperation of the telescopic seat, the limit ball and the limit spring, thereby limiting the position of the limit sleeve and preventing the limit sleeve and the glove from slipping out during processing.

[0020] 3. Designed for flexibility of use: The limiting ball can roll in the limiting snap ring groove, allowing the limiting sleeve to rotate in the limiting access hole. The hand can more flexibly adjust its position inside the processing chamber, thereby improving operational flexibility. After processing, the limiting sleeve and gloves can be easily pulled out of the limiting access hole, facilitating the removal of the denture. At the same time, when the gloves are damaged, they can be more conveniently maintained and replaced, thereby improving processing efficiency.

[0021] 4. The sandblasting gun can adjust the degree of refinement: the lower end of the sandblasting gun is connected to the swivel slide through a limit slider. The lower end of the swivel slide is equipped with two processing nozzles with different inner diameters of the lower end openings. The sandblasting gun can adjust the degree of refinement of the denture processing through the processing nozzles with different inner diameters. It can perform large-area integrated processing of the denture and small-area refinement processing to meet different processing needs.

[0022] 5. Connection stability: The locking clamp on the limit slider cooperates with the locking clamp hole on the inner wall of the swivel slide. When the processing nozzle changes position, it can limit the position of the limit slider and the swivel slide. When the sandblasting port at the lower end of the sandblasting gun is aligned with the opening at the upper end of the processing nozzle, the locking clamp is clamped into the locking clamp hole under the action of the locking spring, ensuring a stable connection between the sandblasting gun and the processing nozzle and stable sand discharge.

Since the inner diameters of the lower end openings of the two processing nozzles 15 are different, and the positions of the two processing nozzles 15 can be transformed by sliding between the limit slider 13 and the swivel slide 14, the sandblasting gun 7 can adjust the fineness of the denture processing by transforming between the two processing nozzles 15 with different lower end opening inner diameters, so that the sandblasting gun 7 can perform large-area integrated processing of the denture, and can also perform small-area fine processing of the denture.

[0039] Preferably, locking sliding holes 16 are provided on the left and right sides of the front and rear ends of the limiting slider 13, and the four locking sliding holes 16 are all located outside the sandblasting gun 7.
