Description

A kind of Novel engineering detection percussion hammer

Technical field

The present invention relates to tap hammer technical field more particularly to a kind of Novel engineering detection percussion hammer.

Background technique

A kind of percussion tool that hammer is used in engineering detecting field is tapped, difference is had according to the weight of tup from big to small Purposes: 50g tup is for detecting the engineerings such as water power Pipe installing, ground decoration, using the sound of percussion vibration, to judge object The firm degree and construction quality of body；25g tup gently beat plastering after metope, it can be determined that the hollowing degree of metope and The bonding quality that sand-lime and brick, cement freeze；10g tup gently beats glass, mosaic, ceramic tile, it can be determined that hollowing degree And bonding quality.

Currently, being connected through a screw thread between the existing tup and hammer handle for tapping hammer, actually tapping in detection, tup and wall The structures such as body are hit for a long time, be will lead to tup and are loosened and rotate around hammer handle, cause the rum point of tup to shift, shadow Ring the judgement of the effect and testing staff that tap, tup rotation is excessive or even can fall down from hammer handle end, be easy to hurt sb.'s feelings or Article is smashed, some potential safety problems is brought.

Summary of the invention

Hammer is tapped to solve the above problems, detecting the invention discloses a kind of Novel engineering, effectively prevents tapping for a long time In the process, the rotation loose phenomenon of tup and hammer handle.

In order to reach the goals above, the invention provides the following technical scheme:

A kind of Novel engineering detection percussion hammer, it is characterised in that: including tapping hammer ontology and the firm component of auxiliary；It is described to strike Hammer ontology includes hammer handle and the tup for being threaded in hammer handle upper end, and the cylindrical structure of hammer handle, the upper end is equipped with Connecting column, the cylindrical structure of connecting column, outside are equipped with the first external screw thread, are equipped with and connect in the middle part of the bottom surface of the tup The compatible link slot of column is connect, is equipped with the first internal screw thread compatible with the first external screw thread in the link slot；The auxiliary is steady Gu component includes the support ring, inner sleeve and housing being sequentially sleeved at outside hammer handle from the inside to the outside, the support ring fixation is set in hammer Outside handle, the inner sleeve structure in a circular table shape, middle part offers through-hole compatible with hammer handle in the axial direction, and through-hole lower end is opened Equipped with support slot compatible with support ring, and the upper end outer diameter of inner sleeve is less than lower end outer diameter, the cylindrical structure of housing, Its middle part offers taper hole compatible with inner sleeve shape in the axial direction, and external circumferential direction is evenly distributed with there are two holding firmware, The holding firmware includes fixing shell, and the fixing shell is the barrel-shaped structure being arranged along hammer handle axis direction, and end opening thereon, The side for fixing shell offers bar shaped slide opening along its axis direction, and one lateral edge of lower end of bar shaped slide opening fixes the circumferential direction side of shell To fixed card hole is offered, clip-connecting rod is fitted in the fixing shell, the clip-connecting rod, which can slide up and down, to be arranged in card Gu in shell, side lower end is equipped with retention bead, lower section is equipped with spring, and the retention bead is slidably disposed in bar shaped slide opening In fixed card hole, inner cavity lower end of the upper and lower ends of the spring respectively with the lower end of clip-connecting rod and fixing shell offsets, institute The upper end for stating hammer handle is also threaded with the ring that is screwed on, the ring that the is screwed on structure annular in shape, and lower end is fixedly connected with abutting set, The abutting covers cylindrical structure, and its lower end and the upper end of housing offset, and the front and rear sides of the tup bottom are symmetrically set There is clamping groove compatible with clip-connecting rod.

Further, the inner sleeve is resilient sleeve.

Further, the internal diameter for pushing against set is not less than the upper-end inner diameter of housing.

Further, the upper end of the hammer handle is equipped with the second external screw thread, the inner wall of the ring that is screwed on be equipped with second outside Compatible second internal screw thread of screw thread.

Further, hold set is arranged with outside the lower end of the hammer handle.

Compared with prior art, it is novel that the beneficial effects of the present invention are: overall structures, by using assisting firm group Part, it can be achieved that fixing to the tup being threadedly coupled with hammer handle, distinguish under the action of the spring by two clip-connecting rods Flexible clamping effectively prevents the rotation loose phenomenon of tup and hammer handle into the clamping groove of tup bottom front and rear sides；Auxiliary Position of the firm component using inner sleeve in such a way that housing combines, after the fixation that can be finally screwed on hammer handle according to practical tup It sets, carrys out rotating jacket, enable clip-connecting rod opposite with clamping groove, and when inner sleeve and housing move toward one another, inner sleeve is in housing Taper hole effect under, can inwardly clamp hammer handle, on the one hand, suitable for different-diameter hammer handle install, before having a vast market On the other hand scape can improve the frictional force of inner sleeve Yu outer inner room, prevent housing from rotating, guarantee the firm effect for assisting firm component Fruit.
