Description

Technical Field

[0001] The utility model relates to the technical field of hole opening, in particular to a special hole opener for aerated bricks. Background Art

[0002] Aerated concrete blocks are a new type of wall material made of stone powder, cement and lime as the main raw materials, which are prepared by raw materials, poured and cut into shape, and cured by high-pressure steam. They are mainly used for non-load-bearing wall masonry and frame structure filling. They are lightweight materials promoted and applied in key industrial and civil fields by the Ministry of Construction and the State Science and Technology Commission. Before using aerated bricks, holes need to be opened;

[0003] At present, the hole drilling of aerated bricks is usually done by the user holding the hole opener body and making a hole by contacting the drill bit with the aerated brick. During the drilling process, the hole position is prone to deviation, resulting in the aerated brick after the hole is drilled being unable to be used normally. The hole drilling accuracy is low and the hole drilling effect is poor. Therefore, we provide a special hole opener for aerated bricks. Utility Model Content

DETAILED DESCRIPTION

[0024] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0025] See also Figure 1-3 , the embodiments of the utility model will be further described below in conjunction with the accompanying drawings.

[0026] Example

[0027] A technical solution adopted by a special hole opener for aerated bricks is: it includes a hole opener body 1, a drill bit 13 is arranged at the bottom of the hole opener body 1, brackets 2 are fixedly connected to both sides of the hole opener body 1, dampers 5 are fixedly connected to both sides of the bottom of the inner surface of the bracket 2, and a spring 4 is wound on the surface of the damper 5, a placement plate 6 is fixedly connected to the top of the damper 5, a pressing plate 7 is fixedly connected to the surface of the placement plate 6, the upper ends of both sides of the bracket 2 are fixedly connected to support plates 14, an electric telescopic rod 15 is fixedly installed on the lower end of one side of the support plate 14, and a cross plate 16 is fixedly connected to one side of the electric telescopic rod 15, and a plurality of limiting wheels 17 are arranged on one side of the cross plate 16.

[0028] Specifically: when it is necessary to drill a hole in the aerated brick, the user presses the pressing plate 7 downward, and the placing plate 6 is driven downward by the pressing plate 7, and the spring 4 and the damper 5 are squeezed to move the placing plate 6 to the lower end of the inner surface of the bracket 2. At this time, the user places the aerated brick on the top of the placing plate 6. After the placement is completed, the user releases the pressing plate 7, and the pressing plate 7 is driven to rebound by the characteristics of the spring 4, so that the top of the aerated brick fits with the drill bit 13. After the fitting is completed, the user starts the electric telescopic rod 15 to work. The electric telescopic rod 15 drives the horizontal plate 16 to move to one side, and drives the limiting wheel 17 to move to one side through the horizontal plate 16, so that one side of the limiting wheel 17 fits with the two sides of the aerated brick to limit it. After the limiting is completed, the user starts the hole opener body 1 to work, and drives the drill bit 13 to rotate through the hole opener body 1. As the depth of the hole is deepened, the placement plate 6 is driven to move continuously upward due to the characteristics of the spring 4, and the rebound is completed, so that the placement plate 6 is completely reset, and the hole opening work can be completed. The hole opening accuracy is high and the hole opening effect is good.

[0029] The drill bit 13 is fixedly connected with mounting blocks 11 on both sides, and the mounting blocks 11 and the hole opener body 1 are fixedly connected by mounting bolts 12. The bottom of the inner surface of the bracket 2 is fixedly connected with a power supply box 10, and the inner cavity of the power supply box 10 is provided with a battery 9. The bottom of the bracket 2 is fixedly connected with support blocks 8, and the support blocks 8 are rubber blocks. Slide grooves 18 are provided on both sides of the inner surface of the bracket 2. Slide blocks 3 are fixedly connected to both sides of the placement plate 6, and one side of the slide block 3 is slidably connected to the inner cavity of the slide groove 18.

[0030] Specifically: the user uses an external tool to rotate the mounting bolt 12 to turn the mounting bolt 12 out of the inner cavity of the mounting block 11 and the hole opener body 1, which is convenient for replacing the drill bit 13. According to the needs of the user, drill bits 13 of different sizes can be conveniently replaced. The device is powered by the battery 9 and the power supply box 10 to maintain the normal operation of the device, and can be used without connecting to an external power supply. The support block 8 is used to effectively support the entire hole opener body 1, and at the same time, the anti-slip function is achieved, which greatly improves the stability of the hole opener body 1. During the movement of the placement plate 6, the slider 3 is driven by the placement plate 6 to slide in the inner cavity of the slide groove 18, thereby reducing the jitter of the placement plate 6 during the movement, thereby greatly improving the stability of the placement plate 6 during the movement.

[0031] The working principle of the utility model is as follows: when it is necessary to perform hole drilling work on the aerated brick, the user presses the pressing plate 7 downward, and the placing plate 6 is driven downward by the pressing plate 7, and the spring 4 and the damper 5 are squeezed to move the placing plate 6 to the lower end of the inner surface of the bracket 2. At this time, the user places the aerated brick on the top of the placing plate 6. After the placement is completed, the user releases the pressing plate 7, and the characteristics of the spring 4 drive the pressing plate 7 to rebound, so that the top of the aerated brick fits with the drill bit 13. After the fitting is completed, the user starts the electric telescopic rod 15 to work, and the electric telescopic rod 15 drives the cross plate 16 to move to one side, and the cross plate 16 drives the limiting wheel 17 to move to one side. Move so that one side of the limiting wheel 17 fits with the two sides of the aerated brick to limit it. After the limiting is completed, the user starts the hole opener body 1 to work, and drives the drill bit 13 to rotate through the hole opener body 1. As the depth of the hole is deepened, the placement plate 6 is driven to move upward continuously due to the characteristics of the spring 4. After the rebound is completed, the placement plate 6 is completely reset, and the hole opening work can be completed. The hole opening accuracy is high and the hole opening effect is good. The user rotates the mounting bolt 12 through an external tool to turn the mounting bolt 12 out of the inner cavity of the mounting block 11 and the hole opener body 1, which is convenient for replacing the drill bit 13. According to the needs of users, drill bits 13 of different sizes can be conveniently replaced.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
