[0003] However, when the staff performs sandblasting operation on the patient's oral cavity, the sand powder will generally splash to the patient's face, reducing the patient's experience during oral treatment. Secondly, the traditional sandblasting protective cover does not have the function of coping with different patient mouth opening areas, and the sand powder is often not fully shielded during sandblasting. Furthermore, the protective cover does not have the functions of rotation and up-down movement. SUMMARY

[0004] The utility model aims at the defects and deficiencies of the prior art and provides a novel sandblasting suction device cover with reasonable design, which can solve the above-mentioned defects.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it includes handle, the handle is connected with arc cover through sliding seat, the arc cover is equipped with adjusting assembly on symmetry, the arc cover is equipped with recess and a plurality of limit slot on symmetry.

[0006] Preferably, the adjusting assembly includes a sliding block arranged in the recess, the sliding block is hinged with a driving rod at both ends, the driving rod is hinged with a rectangular plate at one end away from the sliding block, and the rectangular plate is provided with a plurality of limiting blocks at the bottom.

[0007] Preferably, the sliding block moves in the recess, and the limiting block moves in the limit slot.

[0008] Preferably, the sliding seat is provided with an annular protrusion, the arc cover is provided with an annular groove, and the annular protrusion is clamped in the annular groove.

[0009] Preferably, the sliding seat is in sliding connection with the handle.

[0010] After adopting the above-mentioned structure, the utility model has the beneficial effects that:

[0011] 1. The utility model sets adjusting assembly on the arc cover in symmetry, which can not only prevent sand powder from splashing to the patient's face when the staff performs sandblasting on the patient, improving the patient's experience during treatment, but also cope with different patient mouth opening areas, so that the patient can be fully shielded from sand powder during treatment.

[0012] The utility model discloses a handle, sliding seat, arc cover and adjusting assembly, and the sliding seat is slidably connected with the handle, and the arc cover is slidably connected with the sliding seat. BRIEF DESCRIPTION OF DRAWINGS

[0021] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor are within the protection scope of the utility model.

[0022] As Figures 1-6As shown in the utility model provide a kind of suction apparatus cover for sand blasting, it includes handle 1, it is convenient for staff to hold this device, and handle 1 is silica gel material, handle 1 is connected with arc cover 3 by sliding seat 2, when staff carries out sand blasting in patient oral cavity, sand powder that can be shielded is sprayed, and prevent sand powder splashes to patient face, arc cover 3 is symmetrically equipped with adjusting assembly 4, adjusting assembly 4 can make this device respond to the area of different population oral cavity opening, arc cover 3 is symmetrically equipped with recess 5 and several limit grooves 6, recess 5 can make sliding block 41 slide, and play the role of limiting, limit groove 6 also can make the limiting block 44 of rectangular plate 43 bottom slide, and play the role of limiting,

[0023] Adjusting assembly 4 includes the sliding block 41 being arranged in recess 5, the both ends of sliding block 41 are hinged with driving rod 42, the end of two driving rods 42 away from sliding block 41 is hinged with rectangular plate 43, and the bottom of two rectangular plates 43 is equipped with several limiting blocks 44;

[0024] Sliding block 41 is active in recess 5, limiting block 44 is active in limit groove 6, by setting recess 5 and limit groove 6, when staff touch sliding block 41 with hand, sliding block 41 and rectangular plate 43 can travel according to predetermined trajectory, and will not appear misplacement phenomenon;

[0025] Ring-shaped protrusion 7 is equipped on sliding seat 2, and ring groove 8 is opened on arc cover 3, and ring-shaped protrusion 7 is clamped in ring groove 8, so that the rotating direction of arc cover 3 can be determined;

[0026] Sliding seat 2 is slidably connected with handle 1, so that arc cover 3 can move up and down along handle 1.

[0027] When using, staff hold handle 1 with hand, and can shield sand powder when spraying, when needing to increase the shielding area of arc cover 3, first push sliding block 41 along recess 5 with hand, sliding block 41 moves driving rod 42, driving rod 42 pushes rectangular plate 43, under the limitation of limit groove 6 at the bottom of rectangular plate 43, the rectangular plates 43 on both sides extend to increase the shielding area, in subsequent use, because the ring-shaped protrusion 7 on the outer periphery of sliding seat 2 is clamped in the ring groove 8 in arc cover 3, staff can rotate arc cover 3 or move arc cover 3 up and down along handle 1 with hand.

[0028] It should be understood that the above specific embodiments of the utility model are only used for example or explanation of the principle of the utility model, and do not constitute the limitation of the utility model. Therefore, any modification, equivalent replacement, improvement, etc. made without deviating from the spirit and scope of the utility model shall be included in the protection scope of the utility model.
