Abstract
The invention discloses a safe impact drill for a building. The safe impact drill comprises an electric drilling and impacting assembly, a drill bit, a buffer device, a reinforced buffer frame body and a buffer type holding part, wherein the buffer device comprises a first pedestal and a second pedestal; the front end of the first pedestal is in threaded connection with the assembly, and a sliding cavity is formed in the first pedestal; a sliding rod is arranged at the front end of the second pedestal, and is connected to the interior of the sliding cavity; a spring is arranged between the sliding rod and the sliding cavity; the reinforced buffer frame body is a parallelogram-shaped strong-strength plastic frame; the buffer type holding part is a trapezoidal strong-strength plastic frame. According to the safe impact drill, under the matching of the sliding device and the spring between the two pedestals and the combination of the two strong-strength plastic frames, substantially only a working part between the safe impact drill and a wall surface is impacted, and impact on the holding and fixing parts is greatly reduced, so that the impact drill is used more safely.
Description
Technical field
The present invention relates to a kind of electric drill device, particularly relate to a kind of safety type Churn drill for building.
Background technology
Churn drill is a kind of electric tools relying on rotation and impact work.Its frequency of impact producing more than 40000 time per minute, and continuous print power can be produced.Can be used for natural stone or concrete.But Churn drill operationally, its impact force produced and seismaesthesia, concerning user, are strongly, especially during continuous firing, cause feeling of numbness can to arm position, thus affect work quality.
Summary of the invention
The present invention is exactly for the problems referred to above, and propose a kind of safety type Churn drill for building, impact site and the holding area of this Churn drill separate, and have employed the cushioning device of multiple location, makes Churn drill operationally greatly alleviate impact seismaesthesia to user.
For reaching above-mentioned technical purpose, present invention employs a kind of safety type Churn drill for building, comprise an electric drill to hit, impact assembly and the removable drill bit being connected to described electric drill and hitting, impact assembly left end, also comprise a buffer, a reinforced buffering support body and a buffer-type holding area;
Described buffer comprise a nose threads connect electric drill hit, impact assembly, the first pedestal of inner band sliding cavity, and comprise second pedestal of a front end with sliding bar; Described sliding bar is connected in sliding cavity and also can horizontally slips along sliding cavity, thus the first pedestal is connected with the second pedestal formation; Spring is provided with between described sliding cavity and sliding bar front end;
Described reinforced buffering support body is a parallelogram highstrenghtpiston framework; Described buffer-type holding area is trapezoidal highstrenghtpiston's framework, and described second base bottom forms removable being fixedly connected with parallelogram highstrenghtpiston framework upper end; Described parallelogram highstrenghtpiston base of frame forms removable being fixedly connected with described trapezoidal highstrenghtpiston's framework;
Described trapezoidal highstrenghtpiston's framework right-hand member is provided with and can controls the gauge tap that electric drill hit, impacted assembly, and is hit with described electric drill by power line, impacts assembly and be connected.
Further, described second pedestal rear end is connected with an implosion guard baffle plate by a slot.
Further, described electric drill hits, impacts bottom assembly and be provided with lighting device.
The present invention is by the carriage between two pedestals, the cooperation of spring and the combination of two highstrenghtpiston's frameworks, impact site of the present invention is made substantially only to result from working position between metope, and the impact greatly reduced gripping, fixed position, thus make the use of this Churn drill safer.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in more detail.
As shown in Figure 1, a kind of safety type Churn drill for building, comprise an electric drill to hit, impact assembly 1 and the removable drill bit 2 being connected to this electric drill and hitting, impact assembly 1 left end, hit at electric drill, impact bottom assembly 1 and be provided with lighting device 13, can be used for illumination when light is bad in Churn drill practicality; Also comprise a buffer, a reinforced buffering support body and a buffer-type holding area simultaneously;
In the present invention, buffer comprise a nose threads connect electric drill hit, impact assembly 1, the first pedestal 4 of inner band sliding cavity 3, and comprise second pedestal 6 of a front end with sliding bar 5; An implosion guard baffle plate 12 is connected with by a slot 11 in the second pedestal 6 rear end; Can be used for the blocking of dust when Churn drill uses; Sliding bar 5 is connected in sliding cavity 3 and also can horizontally slips along sliding cavity 3, thus the first pedestal 4 is connected with the second pedestal 6 formation; Between sliding cavity 3 and sliding bar 5 front end, be provided with spring 7 simultaneously; This is first cushioning device in the present invention.
In the present invention, reinforced buffering support body is a parallelogram highstrenghtpiston framework 8; Buffer-type holding area is that the bottom of trapezoidal highstrenghtpiston's framework 9, second pedestal 6 forms removable being fixedly connected with the upper end of parallelogram highstrenghtpiston framework 8; Removable being fixedly connected with is formed with trapezoidal highstrenghtpiston's framework 9 bottom parallelogram highstrenghtpiston framework 8; By this kind of connected mode by bottom the second pedestal 6, parallelogram highstrenghtpiston framework 8 and trapezoidal highstrenghtpiston's framework 9 three be connected together, owing to being frame-like structures with trapezoidal highstrenghtpiston's framework 9 bottom parallelogram highstrenghtpiston framework 8, centre there is no any solid and connects, and vibration is what to need by tangible object transfer, therefore produce second cushioning device of the present invention.
Be provided with at trapezoidal highstrenghtpiston's framework 9 right-hand member of the present invention and can control the gauge tap 10 that electric drill hit, impacted assembly 1, and hit with electric drill by power line, impact assembly 1 and be connected.
In the present invention, to be connected with sliding cavity 3 by sliding bar 5 between the first pedestal 4 and the second pedestal 6 and after being equipped with spring, greatly can to alleviate the vibration produced when Churn drill impacts; Parallelogram highstrenghtpiston framework 8 and trapezoidal highstrenghtpiston's framework 9 are frame construction, electric drill hits, impacting the impact force produced when assembly 1 works can only along frame transmission, quantity is very limited, thus significantly reduce the vibratory sensation of hand, even if worker grips work for a long time, hand also can not produce feeling of numbness.
