DETAILED DESCRIPTION

[0017] With reference to the accompanying drawings Figures 1 to 4 The utility model provides a civil engineering drilling dust cover, including the cover body for collecting dust, the cover body includes interval arrangement fitting plate 101 and fixed ring 102, and the interval of fitting plate 101 and fixed ring 102 can change, and the outside of fitting plate 101 and fixed ring 102 is equipped with flexible dustproof layer 103, and dustproof layer 103 can be rubber pad or dustproof cloth etc., and the both ends of dustproof layer 103 are fixed around fitting plate 101 and fixed ring 102 respectively, and fitting plate 101, fixed ring 102 and dustproof layer 103 form a height variable cylinder or cone and are equipped with through -hole for drill to pass through in axial position. Fitting plate 101 can be fitted with wall surface, and drill passes out from the through -hole of fitting plate 101 and carries out drilling, and the dust produced by drilling enters the inside of cover body from the through -hole, avoids the diffusion of dust to the outside, preferably, fitting plate 101 is equipped with dustproof filler between wall surface, for example, foam or sponge etc., and dustproof filler is arranged in the side of fitting plate 101 close to wall surface. The inside of cover body is equipped with the tensioner of tensioning dustproof layer 103, and the tensioner is arranged between fitting plate 101 and fixed ring 102, and the tensioner includes sliding sleeve 104 and fixed sleeve 105 that can slide to each other, one end of fixed sleeve 105 is fixedly connected with fixed ring 102, the other end of fixed sleeve 105 is slidably connected with sliding sleeve 104, and sliding sleeve 104 is sleeved on the outside of fixed sleeve 105, one end of sliding sleeve 104 is slidably connected with fixed sleeve 105, the other end of sliding sleeve 104 is abutted with fitting plate 102, and elastic piece 106, for example, spring is arranged between sliding sleeve 104 and fixed ring 102. Fixed ring 102 is further equipped with fixing device for fixing with electric drill, and the fixing device includes two semicircular annular buckle 109. Two annular buckle 109 are connected with a screw and form a circular ring, and two annular buckle 109 are arranged on the outside of the shell of electric drill, and two annular buckle 109 fix electric drill on the inside, to realize the fixing of cover body and electric drill, and a plurality of connecting struts 108 are arranged between annular buckle 109 and fixed ring 102, and adjacent two connecting struts 108 have gap, to facilitate the mounting and dismounting of drill on electric drill.

[0018] Figure 3In the middle, the sliding sleeve 104 near the bonding plate 101 has a through hole 111 in its circumferential direction for dust to enter the inner side of the cover. Dust during the drilling process enters the inner side of the bonding plate 101 and enters the inner side of the dustproof layer 103 through the through hole 111 on the sliding sleeve 104, which facilitates the temporary collection of dust.

[0019] See Figure 2 In this structure, one end of the elastic element 106 abuts against the fixing ring 102, and the other end of the elastic element 106 abuts against the right side of the sliding sleeve 104. A limiting ring is provided on the right side of the sliding sleeve 104, and the limiting ring abuts against the elastic element 106. To prevent the elastic element 106 from being trapped in dust inside the dustproof layer 103, the elastic element 106 can be placed between the left end of the sliding sleeve 104 and the fixing ring 102, so that one end of the elastic element 106 abuts against the fixing ring 102 and the other end of the elastic element 106 abuts against the left end of the sliding sleeve 104. A dustproof cloth or rubber layer is provided on the outside of the elastic element 106 to isolate dust.

[0020] Figure 4 In the middle, the bonding plate 101 has cleaning holes 112 for cleaning dust from the inside of the cover.

[0021] Through the above structure, the dust cover is first fixed to the electric drill by a fixing device. The elastic element 106 in the tensioning device is in a free extension state. The elastic element 106 keeps the fixing ring 102 and the bonding plate 101 away from each other. The away fixing ring 102 and the bonding plate 101 keep the dust cover 103 in a tensioned state. The cover is in the shape of a column or a cone. During drilling, because the bonding plate 101 is in contact with the wall, the dust generated by the drill bit can enter the inner side of the cover. When the drilling depth is increased, the electric drill is pushed closer to the wall. The electric drill transmits the thrust to the fixed ring 102 through the annular buckle 109 and the connecting support 108. The fixed ring 102 compresses the elastic element 106, and the sliding sleeve 104 slides relative to the fixed sleeve 105, so that the left and right width of the fixed ring 102 and the bonding plate 101 is reduced. The drill bit moves relative to the wall, increasing the drilling depth. That is, the distance that the fixed ring 102 moves relative to the bonding plate 101 is equal to the drilling depth. After drilling is completed, the bonding plate 101 is placed in a horizontal position, and the dust accumulated inside the cover can flow out from the cleaning hole 112 under its own gravity.

[0022] See Figure 2 Preferably, the inner side of the fixed sleeve 105 is provided with an adjusting sleeve 107 that is threadedly connected to it. One end of the adjusting sleeve 107 extends to the inner side of the sliding sleeve 104, and the other end of the adjusting sleeve 107 extends to the outer side of the fixed ring 102. Figure 2The other end of the adjusting sleeve 107 extends to the left side of the fixing ring 102, and the outer side of the adjusting sleeve 107 is provided with a locking ring 110 which is threadedly connected with the adjusting sleeve 107 and is arranged on the left side of the fixing ring 102. When the adjusting sleeve 107 rotates relative to the fixing sleeve 105, the adjusting sleeve 107 can move towards the fitting plate 101. Figure 4 The fitting plate 101 is provided with a depth measuring hole 113, and the drill bit can contact the right side of the adjusting sleeve 107 after penetrating into the depth measuring hole 113 to a certain depth.

[0023] The adjusting sleeve 107 can move relative to the fitting plate 101, and at this time, when the sliding sleeve 104 slides relative to the fixing sleeve 105, the fitting plate 101 can first contact the adjusting sleeve 107 to prevent the sliding sleeve 104 from continuing to slide relative to the fixing sleeve 105. That is, the sliding distance of the adjusting sleeve 107 relative to the fitting plate 101 is equal to the sliding distance of the fixing ring 102 relative to the fitting plate 101, that is, the sliding distance of the adjusting sleeve 107 relative to the fitting plate 101 is equal to the depth of the drill hole. Therefore, for a hole with a depth requirement, the adjusting sleeve 107 is rotated relative to the fitting plate 101 in advance, and the distance between the adjusting sleeve 107 and the fitting plate 101 is equal to the drilling depth. The drill bit can be penetrated into the depth measuring hole 113 and contacted with the adjusting sleeve 107, and the depth of the drill bit is equal to the distance between the adjusting sleeve 107 and the fitting plate 101. When the distance between the adjusting sleeve 107 and the fitting plate 101 is adjusted, the locking ring 110 is rotated to move the locking ring 110 close to the fixing ring 102, and the locking ring 110 is close to the fixing ring 102 and generates a certain pre-tightening force to fix the adjusting sleeve 107 and the fixing sleeve 105, so that the adjusting sleeve 107 cannot rotate relative to the fixing sleeve 105. The present application can limit the drilling depth in advance, ensure that the drilling depth meets the installation requirements, and improve the drilling quality and efficiency.
