Abstract
The invention discloses a kind of electric hammer drills with protective cover; it includes that sleeve is equipped in shell; impact pole is installed in sleeve; impact pole side connects drill bit, and the impact pole other side connects deboost axle, and deboost axle connects rotary shaft by shaft coupling; rotary shaft connects cushion block; rotary shaft connects transmission shaft with pinion gear by transmission gear, and transmission shaft connects motor, sleeve connection protective cover by driving gear.Technical problem to be solved by the invention is to provide a kind of electric hammer drills with protective cover; it can be by installing transparent protective cover outside drill bit; it can be in the case where not influencing the operator drilling visual field; the dust and clast generated when by drilling is reduced to a certain range; it is not only convenient for having drilled and carries out cleaning cleaning, additionally it is possible to prevent clast splashing from operator being caused to injure unexpectedly.
Description
Technical field
The present invention relates to a kind of electric hammer boring devices, more particularly to a kind of electric hammer drill with protective cover.
Background technique
It is practiced today of many years in building field, building field is subdivided into many branch fields and is furtherd investigate, with
The development of modern technologies, there are many professional very strong tools in different field, electric drill hammer is house ornamentation under building field
One of the common tool in field, electric drill hammer can be good at working on metope, and sizeable peace is drilled out on metope
Hole is filled, so that various articles and equipment are fixed on metope, when electric hammer drill carries out bore operation often with a large amount of wall
Wall powder and small clast, the wall clast of splashing are not only the possibility to fall into the eye of operator and cause serious injury, have yet
The exposed skin of operator may be scratched, works under poor environment and is easy to appear the danger of infection.Therefore one kind is needed
Scheme solves the above problems.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of electric hammer drills with protective cover, can be by outside drill bit
Transparent protective cover is installed, can not influence operator drill the visual field in the case where, by the dust that generates when drilling and broken
Bits are reduced to a certain range, and being not only convenient for having drilled carries out cleaning cleaning, additionally it is possible to prevent clast splashing from operator being caused to anticipate
Outer injury.
The present invention is to solve above-mentioned technical problem by following technical proposals:
A kind of electric hammer drill with protective cover comprising: shell, sleeve, impact pole, drill bit, deboost axle, shaft coupling, rotary shaft, pad
Block, transmission gear, pinion gear, transmission shaft, driving gear, motor, protective cover, caging bolt, heat dissipating housing, damping spring and portable
Handle is equipped with sleeve in the shell, impact pole is equipped in the sleeve, the impact pole side connects drill bit, described
The impact pole other side connects deboost axle, and the deboost axle connects rotary shaft by shaft coupling, and the rotary shaft connects cushion block, described
Rotary shaft connects transmission shaft with pinion gear by transmission gear, and the transmission shaft connects motor, the sleeve by driving gear
Protective cover is connected, prevents the clast to splash during boring hammer from accidentally injuring operator.
Preferably, the sleeve is immobilized in the shell by caging bolt.
Preferably, heat dissipating housing is installed on the right side of the shell, for radiating for shell, prevents overheat from electric hammer drill being caused to damage
It is bad.
Preferably, the impact pole is wrapped with damping spring, for reducing the impact force generated when impact pole work.
Preferably, the shell lower end connects portable handle, holds with a firm grip electric hammer drill for operator, prevents it in operation
Accidentally injure oneself.
The positive effect of the present invention is that: a kind of electric hammer drill with protective cover of the present invention is guaranteeing to bore brill point
Under the premise of the operation of hole, by installing transparent protective cover outside drill bit, operator can not only be protected not splashed broken
Bits scratch, additionally it is possible in a certain range by the dust Control generated when drilling, so as to the cleaning work after the completion of operation, simultaneously
Heat dissipating housing is installed in housing rear end, can radiate, prevent for motor and rotary shaft in the case where electric hammer drill continuous work
Only enclosure interior overheat causes electric elements to damage.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Wherein, shell 1, sleeve 2, impact pole 3, drill bit 4, deboost axle 5, shaft coupling 6, rotary shaft 7, cushion block 8, transmission gear
9, pinion gear 10, transmission shaft 11, driving gear 12, motor 13, protective cover 14, caging bolt 15, heat dissipating housing 16, damping spring
17, portable handle 18.
Specific embodiment
Present pre-ferred embodiments are provided with reference to the accompanying drawing, in order to explain the technical scheme of the invention in detail.
As shown in Figure 1, a kind of electric hammer drill with protective cover comprising: sleeve 2, installation in sleeve 2 are installed in shell 1
There is impact pole 3,3 side of impact pole connects drill bit 4, and 3 other side of impact pole connects deboost axle 5, and deboost axle 5 is connected by shaft coupling 6
Rotary shaft 7 is connect, rotary shaft 7 connects cushion block 8, and rotary shaft 7 connects transmission shaft 11, transmission shaft by transmission gear 9 and pinion gear 10
11 connect motor 13 by driving gear 12, and sleeve 2 connects protective cover 14, prevent the clast to splash during boring hammer from accidentally injuring behaviour
Make personnel.
Sleeve is immobilized in the shell by caging bolt.
Heat dissipating housing 16 is installed on the right side of shell 1, for radiating for shell 1, prevents overheat from electric hammer drill being caused to damage.
Impact pole 3 is wrapped with damping spring 17, for reducing the impact force generated when impact pole 3 works.
1 lower end of shell connects portable handle 18, holds with a firm grip electric hammer drill for operator, prevents it from accidentally injuring oneself in operation
Oneself.
The positive effect of the present invention is that: a kind of electric hammer drill with protective cover of the present invention is guaranteeing to bore brill point
Under the premise of the operation of hole, by installing transparent protective cover outside drill bit, operator can not only be protected not splashed broken
Bits scratch, additionally it is possible in a certain range by the dust Control generated when drilling, so as to the cleaning work after the completion of operation, simultaneously
Heat dissipating housing is installed in housing rear end, can radiate, prevent for motor and rotary shaft in the case where electric hammer drill continuous work
Only enclosure interior overheat causes electric elements to damage.
Particular embodiments described above, the technical issues of to solution of the invention, technical scheme and beneficial effects carry out
It is further described, it should be understood that the above is only a specific embodiment of the present invention, is not limited to
