Abstract

The utility model discloses an adjustable buckle for preventing bolt loosening, which comprises a clamping sleeve (1), wherein one end of the clamping sleeve (1) is provided with a regular hexagon bayonet (2); the clamping sleeve (1) is internally clamped with a clamping strip (3), and one end of the clamping strip (3) is also provided with a regular hexagonal bayonet (2). The utility model discloses a be equipped with regular hexagon's bayonet socket in the one end of cutting ferrule, and also be equipped with regular hexagon's bayonet socket in the one end of card strip, through cup jointing the bayonet socket that corresponds the size with the bolt top, carry out the joint with cutting ferrule and card strip again, when machinery shakes, the trend of two bolts upwards outwards twisting out is offset through cutting ferrule and cutting ferrule to prevent the problem that the bolt slowly withdraws from under the vibrations environment, reduced the potential safety hazard; meanwhile, the bolts do not need to be frequently checked for many times, and are not required to be screwed down for many times, so that the operation is convenient. The utility model discloses not only can reduce the potential safety hazard, still have the operation more convenient, application scope is wide and connection stability is stronger advantage.

Description

Adjustable buckle for preventing bolt from loosening
Technical Field
The utility model relates to a buckle structure, especially an adjustable buckle that prevents the bolt not hard up.
Background
At present, bolts are used for directly fixing some common mechanical devices, but in some operating environments with large vibration (such as oil-water-gas pipeline flanges, copper bar joints, high-pressure container access doors and the like in hydropower stations), the bolts are easy to loosen, and certain potential safety hazards exist; and the operation is troublesome because frequent overhaul and tightening are required. Therefore, the existing bolt fixing mode has the problems of large potential safety hazard and troublesome operation.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a prevent not hard up adjustable buckle of bolt. The utility model discloses not only can reduce the potential safety hazard, still have the more convenient advantage of operation.
The technical scheme of the utility model: an adjustable buckle for preventing a bolt from loosening comprises a clamping sleeve, wherein a regular-hexagon bayonet is arranged at one end of the clamping sleeve; a clamping strip is clamped in the clamping sleeve, and a regular-hexagon clamping opening is also formed in one end of the clamping strip.
In the adjustable buckle for preventing the bolt from loosening, a plurality of clamping grooves which are linearly distributed side by side are formed in the side wall of the clamping sleeve; a groove is formed in one side face of the clamping strip, a limiting column is arranged in the groove, and a spring is fixedly connected between the limiting column and the bottom of the groove.
In the adjustable buckle for preventing the bolt from loosening, the magnet piece is fixed on the bayonet.
Compared with the prior art, the utility model improves the prior bolt fixing mode, the bayonet of the regular hexagon is arranged at one end of the clamping sleeve, the bayonet of the regular hexagon is also arranged at one end of the clamping strip, the clamping sleeve and the clamping strip are clamped by sleeving the bayonet of the corresponding size with the top of the bolt, and when the machine vibrates, the trend of screwing out the two bolts is counteracted by the clamping strip and the clamping sleeve, thereby preventing the problem that the bolts slowly withdraw from the vibration environment and reducing the potential safety hazard; meanwhile, the bolts do not need to be frequently checked for many times, and are not required to be screwed down for many times, so that the operation is convenient. In addition, the side wall of the cutting sleeve is provided with a plurality of clamping grooves which are linearly distributed side by side, one side surface of the clamping strip is provided with a groove, a limiting post which is fixedly connected with the bottom of the groove through a spring is arranged in the groove, and the limiting post can be matched and clamped with the clamping grooves under the action of the spring, so that the distance between the two clamping openings after the cutting sleeve and the clamping strip are clamped can be limited adjustably, the clamping sleeve can adapt to various bolt intervals, and the application range is wider; the bayonet is fixed with the magnet piece, and the magnet piece enables bayonet and bolt zonulae occludens, can not deviate from under the vibrations environment, and connection stability is stronger. Therefore, the utility model discloses not only can reduce the potential safety hazard, still have the operation more convenient, application scope is wide and connection stability is stronger advantage.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a schematic structural view of a card strip.
The labels in the figures are: the magnetic card comprises a card sleeve 1, a card opening 2, a card strip 3, a card slot 4, a groove 5, a limiting column 6, a spring 7 and a magnet piece 8.
Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
Examples are given. An adjustable buckle for preventing a bolt from loosening is shown in figures 1 and 2 and comprises a clamping sleeve 1, wherein a regular-hexagon bayonet 2 is arranged at one end of the clamping sleeve 1; the clamping sleeve 1 is internally clamped with a clamping strip 3, and one end of the clamping strip 3 is also provided with a regular hexagonal bayonet 2.
The side wall of the cutting sleeve 1 is provided with a plurality of clamping grooves 4 which are linearly distributed side by side; a groove 5 is formed in one side face of the clamping strip 3, a limiting column 6 is arranged in the groove 5, and a spring 7 is fixedly connected between the limiting column 6 and the bottom of the groove 5; and a magnet piece 8 is fixed on the bayonet 2.
The working principle is as follows: the regular hexagonal bayonet 2 on the clamping sleeve 1 is sleeved with the top of a regular hexagonal bolt with the same size, and the regular hexagonal bayonet 2 on the clamping strip 3 is sleeved with the top of another regular hexagonal bolt with the same size; at the moment, the magnet piece 8 on the bayonet 2 is tightly absorbed with the top of the bolt, so that the bayonet 2 is not easy to fall off from the top of the bolt; then, the clamping strip 3 extends into the clamping sleeve 1, the limiting column 6 on the clamping strip 3 is matched and clamped with the clamping groove 4 when passing through the clamping groove 4 on the clamping sleeve 1, if the position needs to be continuously adjusted, a user can press the limiting column 6 from the clamping groove 4, the limiting column 6 compresses the spring 7 to retract into the groove 5, and then the clamping strip 3 is pushed; the user adjusts the position of the limiting column 6 and the clamping groove 4 on the clamping sleeve 1 relative to each other according to the distance between the two bolts.
