Abstract
The utility model relates to an electric hammer, electric pick anti -channeling mechanism, beater mechanism in casing and built -in casing, the beater mechanism is including strikeing pole, eccentric wheel and eccentric shaft, and it even has the eccentric wheel to strike the terminal of pole, and the eccentric wheel cover is on the eccentric shaft, it has a perforating hole to open on the casing, and this perforating hole lies in the eccentric wheel directly over, and it is protruding to be equipped with an annular at the medial surface lower extreme of perforating hole, and still has a square oil cap that seals the perforating hole on the perforating hole. The utility model has the advantages of: annular arch has been increased on original basis, like this for drunkenness is not from top to bottom understood to the eccentric wheel, and then can not influence the work efficiency of electric hammer, electric pick, simultaneously, from the inside oiling of perforating hole, and be equipped with the oil cap outside the perforating hole, can make things convenient for and in time more change oil, simultaneously, prevent its during operation, the outside spill of oil.
Description
Technical field
The utility model relates to electric hammer, electric pick technical field, particularly a kind of electric hammer, electric pick anti-jumping mechanism.
Background technology
Electric hammer utilizes piston movement, Compressed Gas drill hammer, do not need hand to make great strength, can perforate on the hard materials such as concrete, brick, stone; Electric pick take single phase series motor as the double insulation hand held electric tool of power, is widely used in pipeline laying, mechanical erection, plumbing Facilities Construction, interior decoration, port facilities construction and other engineering constructions; Thus electric hammer, electric pick are applied in life is very extensive.
Existing electric hammer, electric pick, generally comprise head capsule and pivoted housing, head capsule is provided with through hole, bearing and sealing ring is respectively equipped with between head capsule and pivoted housing, and the outer peripheral face of the inner peripheral surface of sealing ring and pivoted housing abuts against, but, the electric hammer of this structure, electric pick, the easy upper and lower play of pivoted housing, and then affect its operating efficiency.
For above-mentioned situation, be necessary the anti-jumping mechanism researching and developing a kind of electric hammer, electric pick.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of electric hammer, the electric pick anti-jumping mechanism that can prevent the upper and lower play of eccentric wheel.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of electric hammer, electric pick anti-jumping mechanism, comprise the beater mechanism in casing and built-in casing, its innovative point is: described beater mechanism comprises impact bar, eccentric wheel and eccentric shaft, the end of impact bar is connected with eccentric wheel, and eccentric wheel is enclosed within eccentric shaft; Described casing has a through hole, this through hole be positioned at eccentric directly over, be provided with an annular protrusion in the medial surface lower end of through hole, and through hole also have one and close the square oil cap of through hole.
Further, described annular protrusion is 1-2mm apart from eccentric distance.
The utility model has the advantage of:
(1) compared with traditional structure, electric hammer of the present utility model, electric pick anti-jumping mechanism, original basis adds annular protrusion, like this, makes eccentric wheel can not play up and down, and then can not affect the operating efficiency of electric hammer, electric pick; Meanwhile, from the inside oiling of through hole, and be provided with oil cap outside through hole, can facilitate and more change oil in time, meanwhile, when preventing its work, oil outwards spills;
(2) in the utility model, annular protrusion is 1-2mm apart from eccentric distance, allows the space leaving any between annular protrusion and eccentric wheel, conveniently sets up sealing ring, is also unlikely to eccentric wheel and annular protrusion and produces and rub, and then destroy annular protrusion.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structure diagram of the utility model electric hammer, electric pick anti-jumping mechanism.
Fig. 2 is the concrete structure schematic diagram of annular protrusion in Fig. 1.
Detailed description of the invention
The following examples can make professional and technical personnel's comprehend the utility model, but are not therefore limited among described scope of embodiments by the utility model.
Embodiment
Electric hammer of the present utility model, electric pick anti-jumping mechanism, form by with lower part: the beater mechanism in casing 1 and built-in casing.
As shown in Figure 1, the beater mechanism in built-in casing comprises impact bar 2, eccentric wheel 3 and eccentric shaft 4, and the end of impact bar 2 is connected with eccentric wheel 3, and eccentric wheel 3 is fixed by nut 7 with the end of impact bar 2, and eccentric wheel 3 is enclosed within eccentric shaft 4.
Casing 1 has a through hole, and this through hole is positioned at directly over eccentric wheel 3, is provided with an annular protrusion 5 in the medial surface lower end of through hole, and through hole also has the square oil cap 6 that closes through hole, and this oil cap 6 is screwed.
More specifically, annular protrusion 5 is 1-2mm apart from the distance of eccentric wheel 3.
Electric hammer of the present utility model, electric pick anti-jumping mechanism, original basis adds annular protrusion, like this, makes eccentric wheel can not play up and down, and then can not affect the operating efficiency of electric hammer, electric pick; Meanwhile, from the inside oiling of through hole, and be provided with oil cap outside through hole, can facilitate and more change oil in time, meanwhile, when preventing its work, oil outwards spills.
The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (2)
1. electric hammer, an electric pick anti-jumping mechanism, comprise the beater mechanism in casing and built-in casing, it is characterized in that: described beater mechanism comprises impact bar, eccentric wheel and eccentric shaft, the end of impact bar is connected with eccentric wheel, and eccentric wheel is enclosed within eccentric shaft; Described casing has a through hole, this through hole be positioned at eccentric directly over, be provided with an annular protrusion in the medial surface lower end of through hole, and through hole also have one and close the square oil cap of through hole.
2. electric hammer according to claim 1, electric pick anti-jumping mechanism, is characterized in that: described annular protrusion is 1-2mm apart from eccentric distance.
