Technical Field

The utility model relates to a hardware and tools technical field, concretely relates to heavy double offset ring spanner that strikes.

Background

A ring spanner is a common mounting and dismounting tool and is usually made of structural steel of carbon or alloy material. A double offset ring spanner is a hand tool for screwing a bolt, a screw, a nut or other screw-threaded fastening members by using a lever principle, and is generally provided with a trepanning for clamping the bolt or the nut at one end or two ends of a handle part, so that the bolt or the nut can be screwed by applying external force to the handle part along the rotation direction of the screw thread when the double offset ring spanner is used.

In places such as equipment machinery and petrochemical, the bolt that uses usually is great, and it is big to dismantle the degree of difficulty, and the bolt can take place the corrosion after using for a long time usually moreover, consequently generally uses heavy impact box spanner, at present, when using impact box spanner, needs two people cooperation operations usually, when striking box spanner, needs alone to hold the handle of box spanner, and another person uses hammer or other instruments to strike. In such an operation mode, the hand of the supporter is easy to be knocked to cause serious damage, and the vibration generated by knocking of the hammer is directly transmitted to the hand of the supporter to be easily damaged.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides a heavy impact double offset ring spanner which is reasonable in structure and can improve the operation safety and the comfort.

The utility model discloses a following technical scheme realizes: the heavy-duty knocking double offset ring spanner comprises a spanner hole and a handle, wherein the cross section of the handle is in an inverted Z shape with a first inclined surface, the first inclined surface is close to the spanner hole, a support sleeve is fixedly arranged at the top of the spanner hole, the axis of the support sleeve is overlapped with the axis of the spanner hole, a rotating sleeve is arranged on the support sleeve, the outer wall of the rotating sleeve is connected with the inner wall of the support sleeve through threads, and a holding handle is arranged on the rotating sleeve;

one end of the holding handle is fixedly connected with the rotating sleeve, the other end of the holding handle rotates around the supporting sleeve, the cross section of the holding handle is in an inverted Z shape with a second inclined plane, the inclined angle of the first inclined plane is the same as that of the second inclined plane, the inclined direction of the first inclined plane is consistent with that of the second inclined plane, and the second inclined plane is located above the first inclined plane and attached to the first inclined plane.

The top of handle is equipped with first magnet, the bottom of gripping handle is equipped with the second magnet, first magnet with the mutual actuation of second magnet.

The outer wall of the supporting sleeve is provided with an external thread, the inner wall of the rotating sleeve is provided with an internal thread, and the internal thread is matched with the external thread.

The inner diameter of the spanner hole is smaller than that of the support sleeve.

Compared with the prior art, the utility model discloses when using, will pull the hole cup joint on the nut, rotate the handle of gripping, the handle of gripping rotates around support sleeve's axis, thus, it just can be reliable stabilizes the box spanner wholly to grasp the handle of gripping, and the end of gripping is kept away from and is strikeed the end, avoid the hammer to strike the hand, and, support person does not directly contact the handle, the vibrations of striking production are through the handle, support sleeve, the rotation sleeve pipe just transmits the hand through the handle of gripping at last, effectively reduced and strikeed the injury of vibrations to the hand, and is rational in infrastructure, whole security and travelling comfort have been improved.

in the figure: 1. hole pulling; 2. a handle; 3. a first inclined plane; 4. a support sleeve; 5. rotating the sleeve; 6. a grip; 7. a second inclined plane; 8. a first magnet; 9. a second magnet.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

As shown in fig. 1-2, the heavy-duty impact ring spanner comprises a spanner hole 1 and a handle 2, wherein the cross section of the handle 2 is in an inverted Z shape with a first inclined surface 3, the first inclined surface 3 is close to the spanner hole 1, a support sleeve 4 is fixedly arranged at the top of the spanner hole 1, the axis of the support sleeve 4 is overlapped with the axis of the spanner hole 1, a rotating sleeve 5 is arranged on the support sleeve 4, the outer wall of the rotating sleeve 5 is in threaded connection with the inner wall of the support sleeve 4, and a holding handle 6 is arranged on the rotating sleeve 5;

one end of the holding handle 6 is fixedly connected with the rotating sleeve 5, the other end of the holding handle rotates around the supporting sleeve 4, the section of the holding handle 6 is in an inverted Z shape with a second inclined surface 7, the inclined angles of the first inclined surface 3 and the second inclined surface 7 are the same, the inclined directions are consistent, and the second inclined surface 7 is located above the first inclined surface 3 and is attached to the first inclined surface 3. Initially, the first inclined surface 3 is overlapped with the second inclined surface 7, so that the holding handle 6 is attached above the handle 2, the whole structure is compact, and the occupied space is small; when the spanner is used, the spanner hole 1 is sleeved on a nut, the holding handle 6 is rotated, the holding handle 6 rotates around the axis of the support sleeve 4 under the action of the threads, preferably, the other end symmetrical to the handle 2 is rotated, so that the whole box end spanner can be reliably stabilized by holding the holding handle 6, the holding end is far away from the knocking end, the hammer is prevented from knocking hands, a supporter does not directly contact the handle 2, and the vibration generated by knocking is transmitted to the hands through the handle 2, the support sleeve 4 and the rotating sleeve 5 and finally the holding handle 6, so that the damage of knocking vibration to the hands is effectively reduced, the structure is reasonable, and the safety and the comfort of the whole spanner are improved; the first inclined plane 3 is arranged, so that the first inclined plane is matched with the second inclined plane 7 to form an overlapped whole, the distance between the handle 2 and the plane where the nut is located is increased, the distance between the handle 2 and the ground or other nut installation surfaces is increased, the probability that the hammer strikes the installation surfaces is reduced, and the operation difficulty of a knocker is reduced; the support sleeve 4 and the rotating sleeve 5 have enough connection length to ensure that the support sleeve 4 and the rotating sleeve 5 can still be reliably connected through threads after the holding handle 6 rotates for a circle.

The top of the handle 2 is provided with a first magnet 8, the bottom of the holding handle 6 is provided with a second magnet 9, and the first magnet 8 and the second magnet 9 are attracted with each other. Set up magnet for when box spanner when not using, grip 6 and the reliable laminating of handle 2 and locking have reduced whole volume, are convenient for accomodate.

The outer wall of the supporting sleeve 4 is provided with an external thread, the inner wall of the rotating sleeve 5 is provided with an internal thread, and the internal thread is matched with the external thread.

The inner diameter of the spanner hole 1 is smaller than that of the support sleeve 4. The hole 1 is communicated with the inside of the support sleeve 4, and the pipe diameter of the support sleeve 4 is larger, so that when the thickness of the nut is larger, the cavity formed by the hole 1 and the support sleeve 4 can be used for reliably sleeving the nut.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
