When the staff puts their arms into the device to operate, the sand inside the device can easily spread out from the opening where the arms are inserted, which not only affects the cleanliness of the working environment, but also may pose a threat to the health of the staff. At the same time, due to the differences in arm lengths of different people, the existing device does not provide ideal support for the arms, which affects the stability and efficiency of the operation to a certain extent. Therefore, the utility model provides a sandblasting processing mechanism for preparing inner crown of denture. Utility Model Content

[0027] The anti-loose sand component 12 is arranged on the front of the box component 11, and includes a rubber connecting sleeve 121 fixedly sleeved inside the insertion opening 115. A dustproof cloth tube 122 is fixedly installed at one end of the rubber connecting sleeve 121 inside the box 111. An elastic rope 123 is fixedly installed at one end of the dustproof cloth tube 122 away from the rubber connecting sleeve 121. The rubber connecting sleeve 121 is installed inside the insertion opening 115. When the user's arm passes through the rubber connecting sleeve 121, the dustproof cloth tube 122 and the elastic rope 123 to enter the box 111, the elastic rope 123 is tightened by its own elasticity and closely attached to the user's arm, thereby preventing the sand inside the device from being scattered from the insertion opening 115, thereby ensuring the cleanliness of the working environment and the health of the staff;

[0028] The support assembly 13 is disposed on the front side of the box assembly 11 and is used to support the arms of the staff.

[0029] In this embodiment, the box assembly 11 also includes a top cover 112 installed on the top of the box 111 through a hinge. A glass mounting frame 113 is installed on the inclined surface of the box 111 through bolts. A transparent glass 114 is fixedly installed inside the glass mounting frame 113. The glass mounting frame 113 can be disassembled and assembled on the inclined surface of the box 111, which is convenient for replacing the glass mounting frame 113 and cleaning the transparent glass 114. The transparent glass 114 is an inclined surface, so the viewing angle is wider, and the staff can observe the processing conditions inside the device more clearly, so as to make timely adjustments to ensure the processing quality.

[0030] In this embodiment, the support assembly 13 includes a mounting plate 131 fixedly mounted on the front side of the box body 111, a card slot 137 is provided on the front side of the mounting plate 131, a first connecting seat 132 is fixedly mounted on the front side of the mounting plate 131, a telescopic sleeve 133 is movably mounted inside the first connecting seat 132 through a connecting pin, a telescopic rod 135 is slidably inserted into one end of the telescopic sleeve 133 and mounted, a positioning knob 134 is threadedly inserted into the left side of the telescopic sleeve 133, a support bracket 136 is fixedly mounted on one end of the telescopic rod 135, the telescopic rod 135 slides inside the telescopic sleeve 133, so that the distance between the support bracket 136 and the front side of the box body 111 can be adjusted, and the telescopic rod 135 is fixed by rotating the positioning knob 134, so that the support bracket 136 can be adapted to support different users' arm lengths, thereby increasing the stability and efficiency of the user's operation.

[0031] In this embodiment, the support assembly 13 also includes a second connecting seat 138 fixedly installed at the bottom of the telescopic sleeve 133, and a support rod 139 is movably installed inside the second connecting seat 138 through a connecting pin. The end of the support rod 139 away from the second connecting seat 138 is movably installed with a third connecting seat 1310 through a connecting pin, and a clamping block 1311 is fixedly installed at one end of the third connecting seat 1310. The clamping block 1311 is inserted into the inside of the clamping slot 137, so that the support rod 139 supports the telescopic sleeve 133. When the device is not in use, the clamping block 1311 is taken out from the inside of the clamping slot 137, and the telescopic sleeve 133 is rotated and lowered at the connection point with the first connecting seat 132 due to its own weight to be folded.

[0032] In this embodiment, the card block 1311 slides and is inserted into the interior of the card slot 137. The outer side surface of the card slot 137 is T-shaped and the interior is rectangular, and the shape of the card block 1311 is T-shaped when viewed from the top, so that the card block 1311 can be inserted into the interior of the card slot 137.

[0033] In this embodiment, electric lifting legs 2 are fixedly installed at the four corners of the bottom of the box body 111. The model of the electric lifting legs 2 is RL-77P3WK. The four electric lifting legs 2 operate synchronously to lift the sandblasting mechanism 1 to a height suitable for the user's work.

[0034] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0035] When working, the user first connects the device to an external power source, so that the four electric lifting legs 2 operate synchronously to lift the sandblasting mechanism 1 to a height suitable for the user's work, and then opens the top cover 112 to put the denture into the box body 111, and then the user rotates the telescopic sleeve rod 133 to make it parallel, and then the block 1311 is inserted into the slot 137, so that the support rod 139 supports the telescopic sleeve rod 133. When the device is not in use, the block 1311 is taken out of the slot 137, and the telescopic sleeve rod 133 is connected to the first connecting seat 132 with its own weight. The contact rotates and descends to fold, and then the user pushes and pulls the telescopic rod 135 to make the telescopic rod 135 slide back and forth inside the telescopic sleeve rod 133, and adjusts the distance between the support bracket 136 and the box body 111. The support bracket 136 is adjusted to a position suitable for the user's arm support. Then, when the user's arm passes through the rubber connecting sleeve 121, the dustproof cloth tube 122 and the elastic rope 123 to enter the box body 111, the elastic rope 123 is tightened by its own elasticity and fits tightly to the user's arm. The user's arm is placed on the top of the support bracket 136 to work.
