Abstract
The utility model provides a wall-cutting piece which comprises a wall-cutting piece body, and at least two sawtooth sets are annularly arranged around the wall-cutting piece body. The wall-cutting piece disclosed by the utility model has the advantages of wall-cutting labor saving, low noises, no dust, enough rigidity, and one-step molding.
Description
Technical field
The utility model relates to mechanical engineering technical field, is specifically related to a kind ofly to open that wall is laborsaving, noise is little, does not play dust, possesses enough rigidity, the one-time formed wall sheet of opening.
Background technology
In the modern house, attractive in appearance for metope, the general cloth of electric wire is in the body of wall the inside.Traditional metope mode of grooving is to use the portable electric annular saw, the gold conjugate diamond saw blade, leave two lines at metope, then with chisel the wall covering between two lines is knocked out, form so a wider wall chase, open the wall method effort with this time-consuming, and noise is large in the time of with electric circular saw cutting metope, and diamond saw blade is when removing wall covering, and a large amount of dust of can kicking up does not meet modern environmental protection standard.
Summary of the invention
Technical problem to be solved in the utility model be to provide a kind of open wall convenient and strength-saving, produce noise little, do not play dust, possess enough rigidity, the one-time formed wall sheet of opening.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: open the wall sheet, comprise out wall sheet sheet body, the described wall sheet sheet body periphery of opening is equipped with at least 2 group sawtooth groups.
As preferably, described sawtooth group comprises left tooth, middle tooth, right tooth that crown is offset that crown is placed in the middle that a crown is offset left to the right, and the tooth of 3 different angles acts on metope simultaneously when opening wall, thereby reaches one-time formed effect, need not repeatedly to repeat, saved simultaneously manpower.
As preferably, described sawtooth group adopts 3 groups, has accelerated the efficient of cutting, and wall is spread out to the active force of saw blade, has prolonged the service life of saw blade, has avoided simultaneously the saw blade number of teeth too much to make manufacturing process become loaded down with trivial details.
As preferably, the crown of described left tooth is offset 3mm left, and the crown of described right tooth is offset 3mm to the right, and the acting in conjunction of the tooth by 2 different directions has disposablely reached desired recess width.
As preferably, the described thickness of opening wall sheet sheet body, left tooth, middle tooth and right tooth is 3mm, thereby possess enough rigidity, simultaneously under this width, open the span of wall sheet from the left hand edge to the right hand edge and reached 9mm, certain beat is arranged when opening the practical operation of wall sheet in addition, the groove width of leaving on the metope is that 1cm is wide at least, thereby meets the requirements.
Beneficial effect:
The utility model adopts that technique scheme provides opens the wall sheet, open wall convenient and strength-saving, produce noise little, do not play dust, possess enough rigidity, can disposablely reach needed effect.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, open wall sheet sheet body 1, sawtooth group 2, left tooth 21, middle tooth 22, right tooth 23.
The specific embodiment
As shown in Figure 1, open the wall sheet, comprise out wall sheet sheet body 1, described wall sheet sheet body 1 periphery of opening is equipped with at least 2 group sawtooth groups 2, described sawtooth group 2 comprises left tooth 21, middle tooth 22, right tooth 23 that crown is offset that crown is placed in the middle that a crown is offset left to the right, and described sawtooth group 2 adopts 3 groups, and the crown of described left tooth 21 is offset 3mm left, the crown of described right tooth 23 is offset 3mm to the right, and the described thickness of opening wall sheet sheet body 1, left tooth 21, middle tooth 22 and right tooth 23 is 3mm.
Specific embodiment described herein only is to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has more used terms such as opening wall sheet sheet body 1, sawtooth group 2, left tooth 21, middle tooth 22, right tooth 23, do not get rid of the possibility of using other term.Using these terms only is in order to describe more easily and explain essence of the present utility model; They are construed to any additional restriction all is contrary with the utility model spirit.
