KR20120127373A - The ratchet wrench with a variable socket for bolt/nut - Google Patents

Abstract

The present invention is a wrench to tighten or loosen various bolt specifications with one variable socket when tightening or loosening the bolt.
In addition, the gears for clockwise rotation or counterclockwise rotation should be separately placed in the form of right-angled triangle teeth in order to change the rotation direction of the trench wrench. It is a wrench to fix it.
In addition, the wrench handles can be turned from 0 degrees to 90 degrees so that the bolt can be easily rotated so that the section requiring less torque can be turned quickly by turning the wrench handle 90 degrees. This gives the bolt a strong torque with little force.
In addition, by making a driver bit connecting rod that inserts a driver bit and fixes it to a variable socket, it is also possible to work with pieces.

Description

Variable Socket Latch Wrench {The ratchet wrench with a variable socket for bolt / nut}

This variable socket latch wrench is a wrench used to loosen or tighten a bolt nut and can be used to loosen or tighten bolts of various sizes with one variable socket.

Also, the wrench handle can be rotated 90 degrees to reduce the working time by quickly rotating the bolts when loosening or tightening.In addition, various screw bits can be inserted into the screw bit connector and dryer bit connector can be attached to the variable socket. The screws can also be loosened or fixed.

When working with bolt nut, a tool called latch wrench is used, and a large number of sockets should be provided according to many bolt nut specifications, and the work speed is very high because the wrench handle is twisted about 3 ~ 4 times to rotate the bolt nut once. slow.

This makes it possible to devise a variable socket latch wrench that allows one bolt to loosen or tighten bolts of many sizes and to turn the wrench handle 90 degrees to quickly rotate the bolt nut.

1. Design a socket that can loosen or tighten many bolt nuts with one variable socket.

2. Design the wrench handle to turn the wrench handle 90 degrees and turn it quickly when loosening or tightening the bolt nut.

3. Devise a wrench that can be equipped with a driver bit connector on the variable socket and plug the driver bits into this connector to work with the driver.

1. The bolt fixing element fixing bolt nut can be changed so that bolt nut of various sizes can be fixed with one socket.

2. Use the handle of the wrench in the form of a straight line. When the bolt nut is rotated quickly to reduce the working speed, the handle should be bent 90 degrees. In this case, the handle should be fixed so that it cannot be bent 90 degrees.

3. Plug the screwdriver connector into the variable socket so that it can be secured, and the other end of the screwdriver into the driver bit.

1. By using one variable socket, it is not necessary to find a socket that meets bolt nuts of various standards, which improves work efficiency, and requires only one variable socket for easy storage and portability.

2. The wrench handle can be bent 90 degrees, so it can be quickly loosened or tightened in the section that does not require strong torque when working bolt nut, which can shorten the working time.

3. Screwdriver bit connecting rod is attached to the wrench and various screw bits are inserted into the connecting rod, so the screw size is big and the wrench is used when working with a driver that requires a large torque.

Figure 1 latch wrench set
This figure is a block diagram of a latch wrench set.
Variable socket 100, wrench handle 200, is composed of a variety of driver bits and driver bit connection 300, variable socket connection 400.
<Figure 2> Variable socket part diagram
This figure is a part of the variable socket 100.
The variable socket 100 is composed of a socket body 101, a spiral rotating plate 102, a bolt fixing element 103, a fixing pin 104.
The socket body 101 mechanically fixes the bolt fixing element 103 and serves as a guide with respect to the moving direction and mechanically couples the spiral rotating plate.
The helical rotating plate 102 is inserted into the lower portion of the socket body 101 and has a spiral groove, and the protrusion of the bolt fixing element 103 is coupled to the spiral groove to turn the spiral rotating plate 102 to fix three bolts. The element 103 can be moved to the center or the outside of the circle at the same time to fix bolt nuts of various specifications.
The bolt fixing element 103 is different only from the protruding portion of the bottom surface and is configured in the same shape, and moved to the center or the outside of the circle by the rotation of the helical rotating plate 102, and the bolt fixing element 103 and the six faces of the hexagon bolt and The bolt is fixed in contact with three angles.
The fixing pin 104 may rotate the spiral rotating plate 102 smoothly and mechanically couple the socket body 101 and the spiral rotating plate 102 to each other.
<Figure 3> Wrench handle parts
This figure is a wrench handle 200 component diagram.
The wrench handle 200 includes a wrench handle body 201, a handle 202, a gear 203, a gear fixing element 204, a handle fixing element 205, and a handle fixing pin 206.
The gear 203 is in the form of a right triangle, as shown in the tooth 203 enlarged drawing, and consists of two parts separately according to the rotation direction, and the gear 203 of each part has a right angle and an inclined surface of the right triangle. It is reversed. Here, the latch of the gear fixing element 204 also has two parts, which are different depending on the part to be caught depending on the direction of rotation. The shape of the gear 203 is a right triangle rather than a general isosceles triangle shape, so that the gear 203 and the gear fixing element 204 and the engaging portion thereof exactly coincide with each other so that the gear 203 is securely fixed.
The wrench handle body 201 and the handle 202 are coupled to the handle fixing element 205 and the handle fixing pin 206.
Pushing the handle fixing element 205 upwards allows the pin in the handle fixing element 202 to come out of the hole in the handle 202 so that the handle fixing pin 206 can be turned 90 degrees as shown in the figure by the axis of rotation. When it is unfolded again, the pin of the handle fixing element 205 enters the hole of the handle 202 by the spring force to fix the wrench handle body 201 and the handle 202 in a straight shape.
<Figure 4> Driver bit connecting rod
The driver bit and the connecting rod 300 is in the form that can be inserted into the various driver bits 302 at one end of the driver bit connecting rod 301 and the other side is composed of a hexagonal pillar to be fixed to the variable socket 100 In addition, various driver operations can be performed using this variable latch latch.

As described in [short description of drawings]

1. The variable socket 100 is connected to the projection of the bolt fixing element 103 to the spiral groove of the spiral rotating plate 102 to fix the bolt nut of various specifications with one socket to watch the spiral rotating plate 102 When turned clockwise or counterclockwise, three bolt fixing elements 103 were moved simultaneously to the center or the outside of the circle.

2. The gear 203 teeth forming the gear 203 of the wrench handle 200 is a right triangle, unlike the two-sided triangular shape of the general gear 203 teeth, and the gear 203 teeth are formed in opposite directions according to the rotation direction. It consists of two parts, the part of the gear fixing element 204 fastening according to the rotation direction of the gear 203 is configured separately, and when the gear 203 is fixed to the gear fixing element 204 and gear teeth at right angles The gear 203 is securely fixed.

In addition, the wrench handle body 201 and the handle 202 of the wrench handle 200 is formed in a joint form so that it can be bent at 90 degrees, so that the wrench handle body 201 and the handle 202 are handled by the handle fixing element 205. It was to be fixed in a straight form or to release the fixing to be able to bend the handle 200 by 90 degrees.

3. The driver bit connecting rod 301 allows various driver bits to be plugged into one end, and the other side is in the form of a hexagonal column so that it can be fixed to the variable socket 100 so that the size of the screw is large with this variable latch wrench. It also makes it easy to work with drivers that require large torque.
