Description

Spanner {AUTOMATIC SPANNER}

The present invention relates to a spanner, and more particularly, to a spanner that is easily disassembled and assembled so that the durability of the socket-type spanner is enhanced as well as the user himself is easy to maintain.

Generally, a spanner is a mechanism used to loosen and tighten a bolt or nut, and is very useful when working in a narrow space compared to a socket wrench used for the same purpose.

Such a spanner is widely known as an open end spanner having an open head portion, a wrench in the form of a socket in which a working surface is formed in a circular groove without opening the head portion, and a combined spanner in the form of a combination thereof.

Referring to FIG. 1, which shows an exemplary dual-use spanner, in the case of a dual-use spanner, a closed hole 12 and an opening 14 in which hexagon nuts or bolts of the same size are inserted at both sides of the handle 10 are formed, respectively. Made of structure.

Thus, it is utilized to loosen or tighten the hexagon nut or bolt by using the closing part 12 or the opening 14.

By the way, when the spanner of such a conventional structure, when tightening or loosening the bolt or nut, the handle 10 should continue to be rotated in one direction, but if there is an obstacle around the handle 10, the handle 10 is inconvenient to use.

In order to improve this, as illustrated in FIG. 2, in particular, the annular work block 30 having the work surface 32 formed in the closing part (see '12 'in FIG. 1) and the work block 30 are inserted. Latch 40 to limit the work block 30 to rotate only in one direction in response to a spring force (not shown) in a fixed state, and a fixing cap 50 to prevent the work block 30 from being separated. There is an example to ensure the ease of operation by configuring the.

Therefore, in the case of the spanner disclosed in Fig. 2, the force is applied only when rotating in one direction, and on the opposite side, the spanner is turned upside down when the bolt or nut is tightened and loosened, thereby greatly increasing the convenience of use.

However, since the structure of the latch 40 is weak, the spanner having such a structure is easily broken when excessive force is applied, and the work surface 32 itself is also worn out. Since only the damaged part can not be replaced, the new spanner itself must be purchased at a time, which was a waste of time and money.

The present invention was created in view of the above-described problems in the prior art, and when the internal parts of the spanner are broken, it can be easily and quickly separated and dismantled so that only the damaged parts can be replaced and then reassembled for use. The main challenge is to provide a spanner that prevents the loss of working time, and implements two latches to increase durability by extending the service life.

According to an aspect of the present invention, there is provided a spanner including a latch wheel and a closed part having a latch embedded therein for restraining the latch wheel to be rotated in only one direction. A snap ring locking groove recessed in an inner circumferential surface of the upper closed part on which the latch wheel is seated; A snap ring inserted into the snap ring locking groove and locked to prevent the latch wheel from being separated; It provides a spanner comprising a washer interposed between the latch wheel and the snap ring.

At this time, the latch is also characterized in that a pair having the same shape are parallel to each other.

In addition, the snap ring is characterized by having a larger diameter than the washer.

In addition, a groove is formed on one side or both sides of the body of the opening, which is opposite to the closed part of the spanner, and a magnet is embedded in the groove.

According to the present invention, the socket-type spanner can be easily disassembled and assembled, so that only broken parts can be replaced when the parts are broken, thereby reducing the cost, and improving the durability by providing two latches in parallel.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment according to the present invention.

3 is an exemplary exploded perspective view of a spanner according to the present invention, Figure 4 is a cross-sectional view taken along the line A-A of Figure 3, Figure 5 is a partial perspective view showing the opening of the spanner according to the present invention.

As shown in Figures 3 to 4, the spanner according to the present invention is a combined spanner having an opening and a closed part together, in particular to improve the structure of the closed part (100).

That is, the spanner according to the present invention has a structure that is easy to disassemble and assemble so that the parts embedded in the closed part 100 can be easily repaired and replaced.

At this time, the closed part 100 has a structure that can loosen or tighten the bolt or nut while continuously rotating in one direction.

To this end, the spanner according to the present invention by fixing the washer 300 and the washer 300 to serve as a spacer while preventing the latch wheel 200, the latch wheel 200 is separated from the closure portion 100. The snap ring 400 is finally installed in order to allow stable spanner operation, and one side of the latch wheel 200 is engaged in one direction thereof to restrict rotation in the coupled direction and rotate in the opposite direction. It is made of a structure that is further provided with a latch 500 to free flow.

In particular, in the present invention, the latch 500 is configured so that a pair is continuously arranged at regular intervals to further enhance durability.

More specifically, the locking portion 110 is formed at the bottom of the closing portion 100, the latch wheel 200 is seated on the locking portion 110.

In addition, a snap ring locking groove 120 into which the snap ring 400 is inserted is formed on an inner circumferential surface of the closed part 100 at intervals of the thickness of the latch wheel 200.

In this case, the diameter of the snap ring 400 is larger than the diameter of the washer 300 so that the snap ring 400 completely includes the washer 300 when the snap ring 400 is installed after the washer 300 is installed. It is preferable to be configured to be fixed.

A tooth 210 is formed on the outer circumferential surface of the latch wheel 200, and a plurality of jaws are formed on the inner circumferential surface of the latch wheel 200 so that they can be tightened or loosened.

On the other hand, the groove (H) is formed in the portion connected to the handle 600 of the inner circumferential surface of the closed part 100, as is conventional, the difference between the existing and the two latches (500) must be installed in parallel to ensure the maximum space It is configured to do that.

In addition, the present invention uses a latch 500 designed to be slightly smaller than the conventional latch in order to install the two latches 500, the spring 520 pushes the latch shaft 510 of the latch wheel 200 The installation structure for engaging the tooth 210 and rotating the latch wheel 200 in only one direction is the same as before.

However, there is a difference in that the latch 500 of the same structure is installed in two consecutive arrangements, and this difference is not a simple difference, but care must be taken in the design of the groove H so that it can be sufficiently installed in a narrow space. Points, such as the need to reduce the size of the latch 500 is a matter that is inherent.

On the other hand, the washer 300 is a circular member, and serves as a kind of spacer.

The washer 300 plays a role of lowering the frictional resistance of the latch wheel 200 since the latch wheel 200 may be disposed between the snap ring 400 and freely flow when the latch wheel 200 rotates.

Lastly, as shown, the snap ring 400 has a hole 410 formed at both ends of the cut ring, which is not closed, and is fixed to the snap ring engaging groove 120 by an elastic force.

That is, during fixing, for example, a tool such as a long rose is inserted into the hole 410, and then the snap ring 400 is closed and then fitted into the snap ring engaging groove 120, and the tool is inserted from the hole 410 at the moment of being fitted. When separated, it can be used in a form that is firmly and securely locked while returning elastically.

Therefore, the operator can easily remove the snap ring 400 if there is only a tool such as a long-row or a similar type of tool so that anyone can easily repair it anytime, anywhere during maintenance or parts replacement.

As described above, the spanner according to the present invention may be regarded as not much different from the conventional one in the unique function of the spanner, but in terms of easy and easy disassembly and assembly of the internal parts of the closed part 100, convenience in use, cost reduction, It is a very innovative structural improvement because it prevents the loss of working time due to replacement repair or purchase.

In addition, as shown in Figure 5, by forming a groove of a predetermined size on one side or both sides of the body of the opening that is the opposite end of the closure portion 100, and the magnet (M), that is, the magnet is fixed to the groove By allowing a tool, such as the spanner of the present invention, to be attached by a magnetic force to a storage cabinet or a storage rack, the storage of the tool can be easily managed and contribute to creating a clean workplace environment.
