Description

TECHNICAL FIELD

[0001] The utility model relates to a quick dismounting tool for lock bolt belongs to dismounting tool field. BACKGROUND

[0002] In the use process of threaded connection structure, under the influence of impact and vibration, the bolt connection structure is prone to looseness and even failure, in order to avoid the harm caused by bolt looseness, various methods of preventing threaded connection structure from loosening are born, such as self-locking nut anti-loosening, double nut anti-loosening, stop washer anti-loosening, welding anti-loosening, glueing anti-loosening and the like. After the installation of the lock bolt is completed, the bolt torsion is large, and the thread is prone to occlusion deformation during operation, especially the bolt using the glueing anti-loosening, the thread gap is filled with thread locking glue, forming a tight connection, so that the thread pair loses the feature of the pair of movement, and it is very difficult to dismount. The ordinary bolt dismounting tool such as wrench can hardly complete the dismounting work of the lock bolt only by torsion. SUMMARY

[0003] The utility model aims at providing a quick dismounting tool for lock bolt to solve the problem of difficult dismounting after the installation of the lock bolt in the prior art.

[0004] In order to achieve the above object, the utility model adopts the following technical scheme: a quick dismounting tool for lock bolt, the quick dismounting tool comprises front section, middle section and rear section connected in sequence; the front section is connected as the connecting part of rivet gun; the middle section is connected as the connecting part of wrench; and the rear section is connected as the connecting part of lock bolt.

[0005] Preferably, the front section is provided in the shape of long circular shaft as the force transmission structure in the working process of rivet gun.

[0006] Preferably, the middle section is provided in the shape of outer hexagon.

[0007] Preferably, the rear section is provided in the shape of inner hexagon, different specifications of hexagonal bits can be installed in the inner hexagon structure, and the hexagonal bits are matched with the lock bolt.

[0008] Preferably, the quick dismounting tool is in the form of one-piece structure.

[0009] Design principle: the form of vibration and torsion is adopted, the impact force generated by the rivet gun is used to vibrate the lock bolt, and then the torsion generated by the wrench by using the lever principle is combined to achieve the purpose of quickly dismounting the lock bolt.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] 1. The problem of difficult dismounting after the installation of the lock bolt can be effectively solved;

[0012] 2. The quick dismounting tool is convenient to carry and use, and efficiency is improved;

[0013] 3. The quick dismounting tool can be applied to dismounting work of different types of lock nuts, and is suitable for different types of lock nuts.

[0014] 4. When the quick dismounting tool is used, only the corresponding hexagonal bit is replaced, and the impact force of the rivet gun and the torsion of the open wrench are combined in the dismounting process, so that the dismounting work of various types of lock nuts can be easily and quickly solved.

[0019] Figures 1-4 In the figure, 1 is a front section, 2 is a middle section, and 3 is a rear section. DETAILED DESCRIPTION

[0020] The utility model will be further described in detail as follows: a quick dismounting tool for lock nuts, the quick dismounting tool comprises a front section 1, a middle section 2 and a rear section 3 connected in sequence; the front section 1 is designed as a long circular shaft and is connected with a rivet gun; the middle section 2 is designed as an external hexagonal structure, which is convenient for cooperation with an open wrench; and the rear section 3 is designed as an internal hexagonal structure, which can be adapted to different types of bits and meet the dismounting work of different types of lock nuts. Specifically as follows: Figures 1-4 1) The front section 1 is designed as a long circular shaft structure: by referring to the structural characteristics of a rivet card receiving rod, the front section 1 is designed as a long circular shaft and is connected with a rivet, and is used as a force transmission structure in the working process of the rivet, so that the impact force generated by the rivet can bring vibration effect to the lock nut.

[0021] 2) The middle section 2 is designed as an external hexagonal structure: the external hexagonal structure of the middle section has a large pre-tightening contact surface, the U-shaped jaw of the open wrench can be sleeved on the two opposite surfaces of the external hexagonal structure, the lock nut can be dismounted by torsion through the lever principle.

[0022] 3) The rear section 3 is designed as an internal hexagonal structure: according to the type of the lock nut to be dismounted, different specifications of hexagonal bits are replaced, so that the dismounting work of various types of lock nuts can be met.

[0023] ​

[0024] Method of use:

[0025] (1) connect the long round shaft structure of the front section 1 of the quick release tool with the rivet gun;

[0026] (2) according to the type of the locking bolt, select the appropriate hex bit and install it in the inner hex structure of the rear section 3 of the quick release tool;

[0027] (3) press the hex bit on the locking bolt that needs to be disassembled, and use the U-shaped jaw of the open-end wrench to cover the two opposite surfaces of the outer hex structure of the middle section 2;

[0028] (4) after pulling the trigger of the rivet gun, rotate the open-end wrench alternately, and use the impact force of the rivet gun and the torsion force of the open-end wrench in combination to complete the disassembly of the locking bolt.
