Abstract

The invention relates to a percussion hammer with a rolling wheel. The percussion hammer comprises a handler handle. The rolling wheel is arranged at one end of the hammer handle, a rubber hammer head is arranged at the other end of the hammer handle, the rolling wheel and the hammer handle form rotating fit connection in the first direction through a first bearing, and the first direction is the direction, pointing to the rolling wheel, of the rubber hammer head. The rolling wheel comprises a wheel ring, and toothed nails are evenly arranged on the wheel ring in the circumferential direction at intervals and are installed on the wheel ring through first compression springs in a floating mode in the radial direction of the wheel ring. A push rod and an abutting push head are arranged in a tube body, the push rod and the tube body form sliding guide fit connection in the first direction, the end, extending into the wheel ring, of the abutting push head is arranged to be in a conical column shape identical with the outline of the inner ring of the wheel ring, the other end of the abutting push head and the push rod form rotating fit connection in the first direction through a second bearing, and the inner ends of the toothed nails and the peripheral surface of the abutting push head form sliding abutting fit. According to the technical scheme, the toothed nails are installed on the wheel ring in the floating mode and are adjusted to be located at working positions and avoiding positions through the push rod and the abutting push head, and thus it is avoided that clothes are pierced or fingers are scratched.

Description

Detailed description of the invention

In order to make objects and advantages of the present invention clearly understand, below in conjunction with embodiment, the present invention is specifically described.Should be appreciated that following word only in order to describe one or more concrete embodiments of the present invention, considered critical is not carried out to the protection domain that the present invention specifically asks.

The technical scheme that the present invention takes is as Fig. 1, 2, 3, shown in 4, a kind of roller percussion hammer, comprise hammer handle 10, one end of hammer handle 10 arranges roller 20, the other end of hammer handle 10 arranges rubber hammer head 40, rubber hammer head 40 and hammer handle 10 are arranged vertically, roller 20 consists of to be rotatably assorted around first direction clutch shaft bearing 241 and hammer handle 10 and is connected, first direction is the direction that rubber hammer head 40 points to the side of roller 20, roller 20 comprises torus 21, the circumferential uniform intervals of torus 21 arranges finger 22, finger 22 to be arranged on torus 21 along the radial floating of torus 21 by the first Compress Spring 231 that (finger 22 embodiment be arranged on torus 21 that floats is numerous, as can be that the mode arranging spring realizes.That is on torus 21, offer the 4th installing hole for installing finger 22 running through torus 21 thickness, the two ends of the 4th installing hole are closing in shape, the shaft that finger 22 is positioned at the 4th installing hole is arranged the boss 221 against the first Compress Spring 231, the first Compress Spring 231 being positioned at the 4th installing hole is set on finger 22.Torus 21 can be arranged to be made up of internal ring and outer shroud for the ease of assembling, as Fig. 3, shown in 4), the internal diameter of torus 21 reduces gradually along first direction, one end of finger 22 extends in the inner ring of torus 21, hammer handle 10 is that a body is formed, be provided with push rod 26 in body and push 25, a push rod 26 and push 25 and set gradually along first direction, push rod 26 and body form slide-and-guide along first direction and are connected, push 25 end extended in torus 21 and be arranged to the cone column consistent with torus 21 inner ring profile, the other end pushing 25 consists of to be rotatably assorted around first direction the second bearing 242 and push rod 26 and is connected, the inner of finger 22 is formed with the outer peripheral face pushing 25 slides against coordinating, push a 25 adjustment finger 22 and be in two states, one is: the sharp nose of finger 22 extends to the working position of torus 21 periphery, it two is: the sharp nose of finger 22 bounces back to dodges position in torus 21, first Compress Spring 231 orders about finger 22 to be changed to dodging position by working position, the second Compress Spring 232 is provided with between push rod 26 and torus 21, second Compress Spring 232 orders about push rod 26 and moves to the side away from torus 21, the periphery of push rod 26 is provided with elastic card claw 261, the tube wall of body is provided with the locking hole of layout corresponding with elastic card claw 261, elastic card claw 261 and the suitable movement to push rod 26 of locking hole are locked, the pressing button 10a that locking hole is shifted out in the end being provided for elastic card claw 261 is provided with in locking hole.During use, promote push rod 26 from the outer end of body and move, the end of elastic card claw 261 falls in locking hole, thus makes to push a 25 sharp nose pushing finger 22 and leak outside and be in working position, realizes the audit function of roller 20.After inspection terminates, the end of elastic card claw 261 is made to shift out locking hole by the pressing of pressing button 10a, such push rod 26, push 25 and move to the side away from roller 20 by the effect of the second Compress Spring 242, the finger 22 being simultaneously in working position also can change into by the driving of the first Compress Spring 341 dodges position.Pressing button 10b is symmetrical arranged two on body.Elastic card claw 261 be resilient metal member form, resilient metal member and push rod 26 arrange in angle and angle points to the side deviating from roller 20, one end of resilient metal member and push rod 26 Joint, the other end of resilient metal member is to the extended projection portion for locking push rod 26, side away from push rod 27, and the shape in projection portion is consistent with the shape of locking hole.Be arranged on torus 21 by finger 22 is floated, by push rod 26 with push 25 and regulate fingers 22 be in working position and dodge position, thus avoid puncturing clothes and scratching fingers.

Further scheme is: push on an end periphery wall of 25 cone columns and offer chute 251, chute 251 is arranged along the circumferential uniform intervals pushing 25, chute 251 is offered along the length direction pushing 25, the inner of finger 22 is arranged in chute 251, and the number of chute 251 is consistent with the number of finger 22.Hammer handle 10 is that a body is formed, and installing hole is inwardly offered in push rod 26 end corresponding with rubber hammer head 40, and in installing hole, the shift knob 301 of installation LED lamp 30, LED lamps 30 is arranged on the outer face of push rod 26.The outer tube wall of body is provided with anti-slip veins.Arrange chute 251 can avoid finger 22 and push 25 between skid, both guarantees synchronous axial system.The inner of finger 22 can arrange one with push 25 and form the wedge slided against coordinating, wedge is positioned at chute 251, drives the effect of finger 22 better like this.Install LED lamp in the end of push rod 26, realize the multi-functional of percussion hammer, the setting of anti-slip veins, is convenient to being affectedly bashful percussion hammer.

The above is only the preferred embodiment of the present invention; should be understood that; for those skilled in the art; to know in the present invention after contents; under the premise without departing from the principles of the invention; can also make some equal conversion to it and substitute, these convert on an equal basis and substitute and also should be considered as belonging to protection scope of the present invention.
