Description

A double-joint ratchet socket wrench

technical field

The utility model relates to the technical field of assembly tools, in particular to a double-joint ratchet socket wrench.

Background technique

In our real life, there is a ratchet wrench, which is characterized by a ratchet device on the head that can be used to control the wrench only to the left or right through the paddle placed on the outside. This ratchet wrench is often used with a socket. Tighten the fastener and adjust the pick, you can turn it in a certain direction to tighten or loosen the fastener. However, when we use it, we often cannot tell the direction of tightening or loosening the fastener. We need to turn it to Feel the tightening or loosening direction of the fastener by the wrench and then adjust the plectrum for reuse, which causes inconvenience in use, and the structure of the plectrum reversing device is complicated and difficult to produce.

There is also a ratchet wrench, which has an inner ratchet, that is, a ratchet pattern is set inside the ring, and the inner ratchet is used after the fastener is sheathed. This ratchet wrench cannot be used for fasteners located in the deep, and its practicability is not strong.

The patent document with the application number 201320667915.9 discloses such a ratchet wrench, which includes a ratchet wrench body, a ratchet, a lock pin, a pin and a spring, and is characterized in that the ratchet wrench also includes two grease nipples, respectively the first grease There is a passage inside the two grease nipples, the passage runs from the top of the grease nipple to the bottom of the grease nipple, the bottom end is provided with threads, the grease nipple is connected with the main body of the ratchet wrench, and the inside of the ratchet wrench main body has A channel in which the spring and the locking pin are housed sequentially from the inside to the outside. Among them, one end of the lock pin is a flat cut surface, and the other end is an oblique cut surface. There is a pin hole on the lock pin near the end of the flat cut surface. The pin hole is used for installing the pin. The pin and the lock pin are perpendicular to each other. The cutting surface is against the ratchet, and the cross section of the lock pin is against the spring. When the utility model is in use, the fastener needs to be turned to tighten or loosen after the fastener is sleeved. However, the part of the utility model with the fastener is a smooth ring, which is easy to slip during the rotation process and cause problems in use. inconvenient.

Contents of the invention

The utility model aims to solve the above problems by providing a double-joint ratchet socket wrench with two front and back socket joints, which can determine the tightening direction of fasteners without changing the direction of a reversing device and without trying to rotate the direction.

The technical scheme for solving the problem of the utility model is to provide a double-joint ratchet socket wrench, which includes a handle and a disassembly structure connected to one end of the handle. The ratchet in the ratchet installation space, the ratchet that forces the ratchet to rotate in one direction, and the double-end joint that follows the rotation of the ratchet, the double-end joint includes a connecting part for fixing with the ratchet and is arranged on Socket joints at both ends of the connection.

Preferably, the dismounting structure is fixedly connected to the handle through a casing; a through hole is provided at the connection between the casing and the handle to facilitate the entry and exit of the pawl.

Preferably, a sleeve is also included, and the handle is sleeved in the sleeve.

Preferably, the handle is a hollow structure, and the pawl is telescopically arranged in the handle through a spring.

Preferably, the end of the handle is provided with an adjusting bolt for adjusting the elasticity of the spring.

The beneficial effects of the utility model:

1. The sleeve joints at both ends of the double-ended joint represent different rotation directions of the ratchet, that is, the direction in which the wrench is tightened or loosened. There is no need for a reversing device, and the structure is simple, easy to operate, and easy to produce.

2. Combining the ratchet with the socket wrench, the ratchet is used as a control tool for the direction of rotation rather than a fastening tool for fastening the fasteners. It is generally suitable for disassembling fasteners in various positions like a socket wrench. The problem of unclear rotation direction of the socket wrench is also overcome.

3. The combination of ratchet, pawl and spring makes the ratchet move smoothly, not easy to get stuck, simple in structure and strong in practicability.

Detailed ways

The following are specific embodiments of the utility model, and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model is not limited to these embodiments.

A double-joint ratchet socket wrench, as shown in FIG. 1 , includes a handle 100 and a disassembly structure 200 connected to one end of the handle 100 . Wherein, the operation of the utility model mainly depends on the ratchet 210 in the disassembly structure 200 and the parts of the double-head joint 220 connected with the ratchet 210 . The double-headed joint 220 includes a connecting part 221 and sleeve joints 222 installed at both ends of the connecting part 221 respectively. The connecting part 221 passes through the central hole of the ratchet 210 and is fixedly connected with the central hole, thereby connecting the double-ended joint 220 and the ratchet 210 , and make the sleeve joints 222 distributed on both sides of the ratchet 210 .

The ratchet 210 and the double-head joint 220 are installed in the housing 230 and connected to the handle 100 through the housing 230 . As shown in FIG. 3 , in this embodiment, the handle 100 is a hollow cylinder inside; the shell 230 is a cylinder with a ratchet installation space 231 inside, and by connecting the axial direction of the handle 100 vertically to the axial direction of the shell 230, Thus, the handle 100 is connected to the disassembly structure 200 , and a through hole is opened at the joint between the handle 100 and the shell 230 , so that the hollow inside of the handle 100 communicates with the hollow inside of the shell 230 .

The ratchet installation space 231 is used to place the ratchet 210 and the double-end joint 220. Therefore, in order to meet the installation requirements of the ratchet 210 and the double-end joint 220, a bottom surface of the housing 230, also called the receiving bottom surface, is provided with a small radius The through hole is only used to allow the sleeve joint 222 to pass through and receive the ratchet 230; the inside of the housing 230 is hollow, and the bottom surface at the other end is called a fixed bottom surface, and a through hole with a larger radius is provided to allow the ratchet 210 to pass through. , at the same time, in order to limit the ratchet 210 from falling out inside the housing 230, a cover plate needs to be added on the fixed bottom surface, and the cover plate is provided with a through hole for the sleeve joint 222 to pass through; so that the ratchet 210 is fixed in the housing 230, and can expose the sleeve joint 222 for connecting fasteners.

The operation of the ratchet 210 needs to be promoted by the pawl 240. As shown in Figure 2, the pawl 240 is installed in the handle 100 which is hollow inside. The through hole connected with the shell 230 is clamped between the gears of the ratchet 210 , and the tail of the smooth pawl 240 is connected to the bottom end of the handle 100 through a spring 250 . In this embodiment, the bottom end of the handle 100 is an adjustment screw 260, which can be adjusted to control the elastic deformation of the spring 250 to fine-tune the force and rotation of the ratchet 210, thereby adjusting to obtain the most comfortable use.

In particular, in this embodiment, there is also a sleeve 300 , and the handle 100 is sheathed in the sleeve 300 to protect the handle 100 and prevent loosening and loss of components of the disassembly structure 200 .

The specific embodiments described herein are only examples to illustrate the spirit of the present invention. Those skilled in the technical field to which the utility model belongs can make various modifications or supplements to the described specific embodiments or replace them in similar ways, but they will not deviate from the spirit of the utility model or go beyond what is stated in the claims. defined range.
