Description

The present invention relates to a striking device, and more particularly to a striking device in which a striking portion is closely positioned and does not fall off and can be conveniently stored.

For example, Taiwanese Patent No. 228723 has been proposed as a conventional striking device, which includes a pedestal having a central axis and a cylindrical rod having a central hole, and the cylindrical rod is a resin product and injects air. The cylindrical rod can be erected on the pedestal by inserting the central axis into the cylindrical rod filled with air. This completes the assembly of the striking device. However, according to such a configuration, there is a problem that, when hitting is repeated, the cylindrical rod slides gradually upward from the original position, and finally hitting becomes impossible.

In order to solve the above problem, US Pat. No. 6,106,443 has been proposed, in which a pedestal is connected to a central tube and a striking rod is joined, and the central tube, the striking rod, The inside of the container is filled with a sponge, but it cannot be conveniently stored by the back of the sponge, resulting in a large storage space and a high transportation cost.

It is a schematic diagram of the union state of the Example of this invention. 1 is an exploded perspective view of an embodiment of the present invention (not including a hitting portion). It is sectional drawing of the Example of this invention. It is a schematic diagram which shows the use condition of the Example of this invention. It is sectional drawing of another Example of this invention.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

First, FIG. 1 to FIG. 4 will be referred to. The striking device according to the present invention includes a base 10, a disk 20, an elastic body 30, a rod 40, a striking portion 50, and a sleeve 60. The pedestal 10 is a hollow ring body, and an open accommodation space 11 is recessed at the bottom thereof, and a groove with a filling hole 12 formed in the center is provided on the upper surface of the pedestal 10, The fluid can flow from the filling hole 12 into the space inside the pedestal 10, so that the pedestal 10 becomes solid and the disk 20 comes into full contact with the groove provided on the upper surface of the pedestal 10. Then, the entire structure is further stabilized and difficult to fall down, and the nut of the screw is screwed into the inner wall of the receiving space 11, so that the impacting device can be easily disassembled and assembled. Thus, the screw does not loosen easily, and a pedestal 21 is formed at the center of the upper surface of the disk 20, and a circular groove with a spiral on the inner wall is formed on the upper surface of the pedestal 21, The elastic body 30 is a disk by the circular groove. 0 and to articulate.

The elastic body 30 is a metal spring, and a spiral is provided on the inner and outer surfaces. A first end 31 of the elastic body 30 is screwed into a circular groove in the cradle 21, thereby further assembling work. For convenience, a hollow rod 40 made of resin is coupled to the second end 32 of the elastic body 30, and a threaded end 43 is formed on the peripheral surface of one end of the rod 40 adjacent to the elastic body 30. The threaded end 43 is threadedly engaged with the second end 32 of the elastic body 30, whereby the elastic body 30 and the rod 40 are fixed. As a result, the strength and toughness of the rod 40 is improved, and the tool is The rod 40 can be assembled without being used, and an engagement end 41 is joined to the other end of the rod 40, and the engagement end 41 is engaged with the striking portion 50. It is connected to the joint end 41, and the engagement end 41 is detached from the rod 40 during storage. Rukoto can, it is possible to save the storage space.

The striking part 50 includes a small-diameter inner bag 51 and a large-diameter outer bag 52, and an air-filling space 53 is provided between the inner bag 51 and the outer bag 52. The inner bag 51 is formed so that one end of the inner bag 51 is an open end, the engagement end 41 of the rod 40 is locked in the throttle space 54, and faces the outer edge of the open end of the inner bag 51 of the rod 40. At the location, the engaging tool 42 larger than the diameter of the open end of the inner bag 51 is projected, an air filling hole 55 is provided on the bottom surface of the outer bag 52, and a sleeve 60 is provided outside the outer bag 52. A positioning portion is provided on the peripheral surface of the bottom surface of the sleeve 60, a fastener 61 is provided on the positioning portion, and an opening is opened on the bottom surface of the positioning portion; The diameter of the opening is smaller than the outer diameter of the engaging member 42, and the threaded end 43 of the rod 40 is at the front. When the positioning portion and the sleeve 60 are joined together by the fastener 61, the sleeve 60 covers the striking portion 50 and the engaging member 42, and when air is injected into the striking portion 50, Since the bag 51 presses the rod 40 and the rod 40 is fixed, and the air filling hole 55 is covered by the sleeve 60, air leakage due to a collision can be reduced, and when it is desired to inject air, the fastener 61 is opened. It is possible to inject air only, and of course, the air filling hole 55 may be protruded from the sleeve 60 in consideration of safety, and the usability is further improved.

Next, another embodiment of the present invention will be described. In another embodiment of the present invention, a metal tube 33 is welded to the second end 32 of the elastic body 30, and a seal lid 44 is formed at one end of the rod 40 adjacent to the elastic body 30. The metal tube 33 is inserted into the rod 40 and fixed to the inside of the rod 40, and the seal lid 44 is put on the outer edge of the elastic body 30, so that it can be avoided that the structure is weakened due to the collision of the metal tube, The strength of the rod 40 increases.

The positioning portion is provided with a binding band (not shown) at the opening of the sleeve, and the striking portion and the engaging tool are positioned inside the sleeve 60 by the binding band, and assembly work and disassembly work are performed. Becomes even easier.

In particular, the striking device according to the present invention has an open accommodating space 11 provided in the bottom of the pedestal, and the accommodating space 11 can accommodate the striking portion where air has leaked, and the total volume after storing is small. As a result, the storage space becomes smaller than the conventional one, and the transportation cost can be reduced.

The present invention can be applied to a striking device.
