Abstract
Description
Technical Field
[0001] The utility model relates to the field of drilling equipment, in particular to an adjustable drilling device. Background Art
[0002] In addition to rotation, the drilling device also has a slight impact force, which can help the impact drill to penetrate hard materials such as concrete, bricks or tiles more easily when drilling, and increase the torque when tightening screws. It is suitable for impact drilling on concrete floors, walls, bricks, stones, wood boards and multi-layer materials for subsequent processing and installation.
[0003] However, most of the current drilling devices have the following problems:
[0004] First, the existing drilling device will produce large vibrations during the handheld drilling process, which increases the difficulty of holding the impact drill by hand. The drilling depth is mostly uncontrollable, and the user needs to judge the drilling depth based on experience. Drilling too deep or too shallow is likely to affect subsequent construction, and it is inconvenient to adjust the drilling according to usage.
[0005] Second, the existing drilling device will inevitably splash dust when drilling, and the subsequent cleaning is more troublesome, which not only pollutes the current environment and affects the health of users, but also affects the visibility of the construction. It is inconvenient to carry out convenient dust collection when drilling.
[0006] Therefore, we make improvements to this and propose an adjustable drilling device. Utility Model Content
[0007] The purpose of the utility model is to solve the existing problems of inconvenience in adjusting the drilling according to the usage situation and inconvenience in performing convenient dust collection.
[0008] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0009] An adjustable drilling device is provided to improve the above problems.
[0010] The specific application is as follows:
[0011] The invention comprises an impact drill body and a drill rod, the drill rod is installed on the impact drill body, a protective shell is fixedly connected to the impact drill body, a block is arranged in the protective shell, a guide block is fixedly connected to the block, a first spring is fixedly connected in the block, the other end of the first spring is fixedly connected to a limiting plate, a pull rod is fixedly connected to the limiting plate, a block is fixedly connected to the pull rod, a second spring is fixedly connected to the block, the other end of the second spring is fixedly connected to a connecting rod, an air distribution box is fixedly connected to the connecting rod, an air distribution box is fixedly connected to an air suction pipe, a delivery hose is fixedly connected to the air distribution box, the other end of the delivery hose is fixedly connected to a collecting box, the collecting box is fixedly connected to the impact drill body, an isolation net is fixedly connected to the collecting box, an air pump is fixedly connected to the collecting box, and a sealing cover plate is bolted to the collecting box.
[0012] As a preferred technical solution of the present application, the blocks are symmetrically distributed on the left and right sides of the protective shell, and the blocks correspond one-to-one with the pull rods through the first spring.
[0013] As a preferred technical solution of the present application, the side end surface of the limit plate is fitted with the inner side surface of the stop block, and the pull rod is fixedly connected to the center part of one side of the limit plate.
[0014] As a preferred technical solution of the present application, the side end surface of the connecting rod end is in contact with the inner side surface of the protective shell, and the intake pipes are distributed at equal angles on the air distribution box.
[0015] As a preferred technical solution of the present application, the isolation nets are symmetrically distributed on the left and right sides of the collection box, and the isolation nets correspond one-to-one with the sealing cover plates through an air pump.
[0016] Compared with the prior art, the utility model has the following beneficial effects:
[0017] In the scheme of this application:
[0018] 1. Through the set stopper, when adjusting and controlling the depth of the drilling hole, the pull rod can be pulled to drive the limit plate to move. When the limit plate moves, it can squeeze the first spring. At the same time, the block on the pull rod can be smoothly separated from the protective shell. When the stopper is unobstructed, the stopper can be pushed to move. When the stopper moves, it can move smoothly with the support of the guide block. When the stopper moves down, the depth of the subsequent drilling can be adjusted. After the adjustment is completed, the pull rod is released, and the limit plate and the pull rod are reset under the push of the spring, and the pull rod is moved up. The block can be stably engaged in the protective shell to fix the block. When drilling, the position can be compared through the air box. When the impact drill body is pressed down and the drill rod is used to drill a hole, the air box can push the connecting rod to move. When the connecting rod moves, the second spring can be squeezed. When the hole is drilled to the adjusted position, the connecting rod cannot move up due to the blocking of the block, and the drill rod can be limited to adjust the depth of the hole. When drilling, the second spring can play a role of buffering and shock absorption to avoid excessive vibration affecting the use.
[0019] 2. Through the set air distribution box, if some dust is generated in the hole during drilling, when dust collection is required, the air pump on the collection box can be turned on, and the air pump will absorb and collect the floating dust through the suction pipe on the air distribution box, and transport the dust to the collection box through the conveying hose on the air distribution box. The dust can be isolated through the isolation net on the collection box to protect the air pump. When the dust in the collection box needs to be removed and cleaned, the sealing cover on the collection box can be removed to clean the dust collected in the collection box to improve the dust removal efficiency.

[0034] Embodiment 2:
[0035] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:
[0036] like Figure 4 As shown, as a preferred embodiment, on the basis of the above method, further, the blocks 4 are symmetrically distributed on the left and right sides of the protective shell 3, and the blocks 4 correspond one-to-one with the pull rods 8 through the first springs 6, which can ensure that the depth of the drilling can be smoothly adjusted under the blocking of the blocks 4 on both sides.
[0037] like Figure 4 As shown, as a preferred embodiment, on the basis of the above method, further, the side end face of the limit plate 7 is fitted with the inner side face of the stop block 4, and the pull rod 8 is fixedly connected to the center part of one side of the limit plate 7, which can ensure that the limit plate 7 can move smoothly through the support of the inner side face of the stop block 4 when moving.
[0038] like Figure 6 As shown, as a preferred embodiment, on the basis of the above method, further, the end face of the connecting rod 11 is fitted with the inner side face of the protective shell 3, and the suction pipes 13 are distributed at equal angles on the air distribution box 12, which can ensure that the multiple suction pipes 13 on the air distribution box 12 can evenly absorb and collect dust.
[0039] like Figure 2 As shown, as a preferred embodiment, on the basis of the above method, further, the isolation net 16 is symmetrically distributed on the left and right sides of the collection box 15, and the isolation net 16 corresponds one-to-one with the sealing cover plate 18 through the air pump 17, which can ensure that the dust absorption efficiency can be improved under the cooperation of the air pumps 17 on both sides.
[0040] Specifically, when the adjustable drilling device is used: Figure 1-6 When the equipment is used for drilling, the air distribution box 12 can be placed at the position where the hole needs to be drilled.
