Abstract
The utility model discloses a depth wrench for a round nut. The wrench comprises a body with a certain height. The body has a hollow structure. A wrench head is arranged at one end of the body. The inner lateral surface of the wrench head is round, and four rectangular teeth matched with a groove reserved on the surface of the round nut are circumferentially and uniformly distributed on the inner lateral surface. The depth wrench is easy to operate, firm in clamping and free of the limitation of a height space.
Description
Technical field
The utility model belongs to machinery production tooling device technical field, is specifically related to a kind of degree of depth round nut spanner.
Background technology
At present, the round nut spanner that when the round nut dismounting, uses, all exist clamp not strongly, moment of torsion is uncontrollable, efficient is low and be subjected to the defectives such as short transverse spatial limitation.
Summary of the invention
The purpose of this utility model provides a kind of degree of depth round nut spanner, and simple to operate, clamping is firm, and is not subjected to the restriction of height space.
The technical scheme that the utility model adopts is, a kind of degree of depth round nut spanner, it is characterized in that, comprise the body with certain altitude, body is hollow structure, one end of body is spanner, and the inner surface of spanner is circular, and is distributed with four rectangular teeths that match with round nut surface fluting along even circumferential on this inner surface.
The other end sealing of body, and have for the center square hole that matches with torque spanner.
The external shape of body is cylindrical.
The outer setting of spanner has reinforcing ring.
The beneficial effects of the utility model are that four rectangular teeths on the spanner match with round nut surface fluting, more effectively the dismounting round nut; Break through the restriction of plain round nut spanner on height space, the scope of application is more extensive; Can be used in conjunction with torque spanner, effectively control screw-down torque.
Description of drawings
Fig. 1 is the structural representation of the utility model degree of depth round nut spanner;
Fig. 2 is the top view of Fig. 1.
Wherein, 1. spanner, 2. rectangular teeth, 3. center square hole.
The specific embodiment
As depicted in figs. 1 and 2, the utility model degree of depth round nut spanner, comprise the body with certain altitude, body is hollow structure, one end of body is spanner 1, the inner surface of spanner 1 is circular, and is distributed with four rectangular teeths 2 that match with round nut surface fluting along even circumferential on this inner surface.The other end sealing of body, and have for the center square hole 3 that matches with torque spanner.The external shape of body is cylindrical.The outer setting of spanner 1 has reinforcing ring.
Four rectangular teeths 2 on the spanner 1 of the present utility model can match with the round nut fluting, thereby firmly effectively clamp round nut, when the dismounting round nut, moment of torsion can be evenly distributed on four rectangular teeths 2, round nut is stressed evenly, both dismounting round nut more effectively can not destroy round nut cylindrical and notch again; Body has certain altitude, has broken through the restriction that the plain round nut spanner is subject in height space, and at the round nut of axle head, the scope of application is more not extensive in easily dismounting; Be used in conjunction with by center square hole 3 and torque spanner, thereby can effectively control screw-down torque, satisfy more accurately the pretightning force of parts requirement.
