Abstract
The utility model discloses a front-lid double anti-drop mechanism of a heavy electric hammer. The utility model is provided with a rotary sleeve, a cutting sleeve assembly and a rubber front lid. The utility model is characterized in that the rotary sleeve is provided with a concave loop; the front lid is provided with a rubber convex loop embedded in the concave loop; the back of the concave loop of the rotary sleeve is provided with a check ring loop in which a check ring blocked at the front end of the cutting sleeve assembly is arranged. The utility model has the advantages that the structure is reasonable; through the double-layer anti-drop mechanism of the check ring and the rubber convex loop, the utility model can effectively prevent associated components, such as the front lid, the cutting sleeve assembly, etc., of an electric hammer in use from falling off; the cost is low; the fabrication is convenient.
Description
Technical field:
The utility model relates to a kind of protecgulum escapement of electric hammer.
Background technology:
The protecgulum of existing heavy electric hammer is made of the sub-assembly of rubber parts, steel part or steel part and rubber.Utilize the elasticity of rubber or be threaded on the pivoted housing.Protecgulum is blocked ferrule assemblies and is prevented the dual-use function that comes off by dustproof closing, electric hammer in use, protecgulum closes under the double action of spring force in the hammering vibration force, protecgulum will produce loosening and come off, spacing ferrule assemblies, spring, the steel ball (or ball) of forward lid also comes off thereupon, causes whole electric hammer not use.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, effectively the protecgulum anti-shedding mechanism of the heavy electric hammer of element falling such as electric hammer protecgulum.
Technical solution of the present utility model is:
The dual anti-shedding mechanism of a kind of protecgulum of heavy electric hammer, pivoted housing, ferrule assemblies, rubber protecgulum are arranged, it is characterized in that: scrobicular ring is set on the pivoted housing, the rubber bulge loop that is entrenched in the scrobicular ring is set on the protecgulum, the scrobicular ring rear of pivoted housing is provided with the back-up ring ring, and the dress retaining is at the back-up ring of ferrule assemblies front end in the back-up ring ring.
Packing ring also is set between back-up ring and the ferrule assemblies.
The utility model is rational in infrastructure, by the two-layer anti-shedding mechanism of back-up ring and rubber bulge loop, can effectively prevent electric hammer coming off of associated components such as protecgulum and ferrule assemblies in use; And low cost of manufacture, easy to process.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the configuration diagram of an embodiment of the utility model.
Fig. 2 is the configuration diagram of pivoted housing among Fig. 1.
The specific embodiment:
The dual anti-shedding mechanism of a kind of protecgulum of heavy electric hammer, pivoted housing 1, ferrule assemblies 2, rubber protecgulum 3 are arranged, scrobicular ring 4 is set on the pivoted housing 1, the rubber bulge loop 5 that is entrenched in the scrobicular ring 4 is set on the protecgulum 3, scrobicular ring 4 rears of pivoted housing are provided with back-up ring ring 6, and the dress retaining is at the back-up ring 7 of ferrule assemblies 2 front ends in the back-up ring ring 6.Between back-up ring 7 and the ferrule assemblies 2 packing ring 8 is set also.
Claims (2)
1, the dual anti-shedding mechanism of a kind of protecgulum of heavy electric hammer, pivoted housing, ferrule assemblies, rubber protecgulum are arranged, it is characterized in that: scrobicular ring is set on the pivoted housing, the rubber bulge loop that is entrenched in the scrobicular ring is set on the protecgulum, the scrobicular ring rear of pivoted housing is provided with the back-up ring ring, and the dress retaining is at the back-up ring of ferrule assemblies front end in the back-up ring ring.
2, the dual anti-shedding mechanism of the protecgulum of heavy electric hammer according to claim 1 is characterized in that: packing ring also is set between back-up ring and the ferrule assemblies.
