Description
Technical Field
The invention relates to a socket wrench, in particular to a connector capable of generating vibration between the socket wrench and a socket.
Background
At present, the nut is mainly disassembled and assembled by a spanner, which comprises various socket spanners, solid-mouth spanners, adjustable spanners, double offset ring spanners and the like. To rusty nut dismouting, can cause six surfaces of nut to skid and can not pull out the condition of nut when utilizing these spanners commonly used to dismantle, often need just can dismantle smoothly with the help of lubricating oil. If a wrench capable of generating vibration is provided, the rusted nut can be smoothly removed.
Currently, there are some studies on the design of vibration wrenches. For example, the vibration wrench (CN 201510659514.2) disclosed in the chinese patent of invention uses a motor to drive an eccentric shaft to vibrate to generate an exciting force; also, as a vibration wrench (CN 201010172715.7) disclosed by the present invention, a motor drives a rotating rod to hit the inner wall of the cavity to generate vibration. The two methods can effectively generate exciting force, but the exciting force is driven by a motor, so a battery needs to be equipped, and the generated vibration directions are not all along the tangential direction of the six sides of the nut, so that the vibration in certain directions does no work, and the maximum vibration unscrewing effect on the disassembly of the nut cannot be exerted. And the two methods are designed into independent wrenches, so that the universality is poor and the cost is high.
Disclosure of Invention
The invention aims to provide a vibrating universal connector for a socket wrench, which can realize vibrating disassembly and assembly of rusty nuts of various specifications or normal disassembly and assembly of normal nuts without changing the shape of the existing socket wrench, and has the advantages of simple structure and good economical efficiency.
In order to solve the problems in the prior art, the invention adopts the following technical scheme:
a vibration type universal connector for a socket wrench comprises,
one end of the upper rotating drum is provided with a connecting hole connected with a handle of the socket wrench;
one end of the lower rotary drum is provided with a connector connected with the sleeve head, and the lower rotary drum is coaxial with the upper rotary drum;
the first pawl is rigidly and fixedly connected with the upper rotary drum, the second pawl is elastically and slidably connected with the upper rotary drum, and the elastic sliding is realized in a sliding mode by generating displacement through elastic deformation;
the first ratchet tooth and the second ratchet tooth are respectively fixedly connected with the lower rotary drum, the first ratchet tooth is coplanar and matched with the first pawl, the second ratchet tooth is coplanar and matched with the second pawl, the tooth directions of the first ratchet tooth and the second ratchet tooth are opposite, and the opposite tooth directions mean that when the first pawl and the second pawl rotate in the same direction, the first pawl slides relatively on the tooth surface of the first ratchet tooth, and the second pawl drives the second ratchet tooth to rotate (the first ratchet tooth and the second ratchet tooth are relatively static).
Furthermore, hollow guide cylinders are uniformly distributed on the circumferential surface of the upper rotary drum.
Further, the first pawl and the second pawl are respectively distributed on two planes which are perpendicular to the axis of the upper rotary drum.
Further, the first pawls are uniformly distributed on the circumference of the lower end of the upper rotary drum.
Further, the second pawl comprises a guide head, a guide rod, a knocking head and a spring;
the guide head is a rod-shaped structural part with a hollow cavity and is connected with the upper rotary drum in a sliding manner along the direction penetrating through the circumferential surface of the upper rotary drum;
one end of the guide rod is connected in the hollow cavity of the guide head in a sliding mode, the other end of the guide rod is connected with the knocking head, and springs are arranged on the outer side of the guide rod and between the knocking head and the guide head.
Further, the first ratchet and the second ratchet are respectively distributed on two planes which are perpendicular to the axis of the lower rotary drum.
Furthermore, the first ratchets are a plurality of ratchets uniformly distributed on the bottom of the annular groove on the circumferential surface of the lower rotary drum.
Furthermore, the second ratchets are uniformly distributed on the circumferential surface of the disc, and the end surface of the disc is fixedly connected with the upper end of the lower rotary drum.
Further, the vibration type universal connector for the socket wrench further comprises an adjusting collar with a variable circumference, the adjusting collar is coplanar with the second pawl and located in the outer circumference of the second pawl, and the second pawl is pressed or loosened through the change of the circumference.
Furthermore, the connecting hole is a square hole, and the connector is a square head.
It should be noted that the present invention refers to pawls and ratchets which are conventional in the art, i.e. pawls which drive a pawl (ratchet) in one direction and in reverse, the pawl slides on the flanks of the ratchets.
The core of the invention lies in the cooperation of two groups of ratchet-pawl mechanisms, particularly the opposite tooth directions of the first ratchet teeth and the second ratchet teeth. The first pawl is rigidly connected with the upper rotary drum, so when the first pawl rotates in a single direction, the first pawl can drive the lower rotary drum to rotate together through the first ratchet, so that the nut screwing effect is realized, at the moment, the second pawl is elastically and slidably connected with the upper rotary drum, and the tooth directions of the second ratchet and the first ratchet are opposite, so that the second pawl slides on the tooth surface of the second ratchet, and the impact vibration is not generated in the sliding direction. When the first pawl rotates reversely, the first pawl slides relatively on the tooth surface of the first ratchet, the upper rotary drum cannot drive the lower rotary drum to rotate, the second pawl drives the second ratchet to rotate, if the nut is rusted, the torque generated by the resistance of the nut is larger than the driving force of the second pawl, the second pawl cannot normally drive the second ratchet, but the second pawl generates elastic displacement and slides due to the forced rotation of the upper rotary drum, the second pawl jumps over the second ratchet matched with the second pawl, then the elastic displacement resets and slides to the other ratchet, and impacts the ratchet, so that tangential vibration impact torque is realized, tangential force is generated through a connecting joint on the lower rotary drum, the effect of loosening the nut is achieved, after the nut is continuously impacted and loosened, the torque generated by the resistance of the nut is smaller than the driving torque generated by the second pawl, at the moment, the second pawl drives the lower rotary drum to rotate by driving the second ratchet, thereby loosening the nut.
The tooth profile of the ratchet teeth is preferably triangular, and particularly when jumping from the short-side tooth surface of one ratchet tooth to the short-side tooth surface of the other ratchet tooth as the difference between the lengths of the two tooth surfaces of the same ratchet tooth is larger, larger impact vibration is generated due to larger elastic displacement of the first pawl.
Compared with the prior art, the invention has the following characteristics:
1. the invention utilizes elastic displacement (such as spring force) to generate the vibrating knocking force, and the vibrating knocking force is adjusted by adjusting the change of the circumference of the lantern ring;
2. the universal joint can realize the vibration type dismounting of rusty nuts with various specifications or the normal dismounting of normal nuts on the premise of not changing the shape of the existing socket wrench, and has simple structure and good economical efficiency.
3. The invention can realize the vibration disassembly of the nut and also can normally realize the screwing process of the nut.
