The device can adapt to bolts of different specifications, is light and handy in structure, is convenient to carry during outgoing operation, and is simple to operate.
Description
Technical Field
The utility model belongs to bolt dismouting technique, concretely relates to little moment of torsion bolt dismouting device.
Background
The bolt dismounting device on the market at present has an open end wrench, a box end wrench, a socket wrench and the like, the types are very many, and each specification bolt has a corresponding wrench; however, when the user goes out, the user needs to have a dismounting tool which can be suitable for bolts with various specifications, so that the user does not need to carry various wrenches, and the bolt dismounting tool is not available at present. One end of the existing adjustable wrench can be adjusted to adapt to bolts with different sizes; however, when the adjustable wrench is used for a bolt having a larger gauge diameter, the weight and length of the adjustable wrench are increased, and the arm power consumption is also a burden, and the adjustable wrench is not suitable for a long time use.
Through exploring and practicing, it is fixed to discover that little moment of torsion bolt dismouting device in market all leans on two contact surfaces, and the pole combination of rethread increase moment, and the structure is fairly simple, and technical content is not high, and is also fairly practical, nevertheless can't satisfy the bolt of various specifications, need carry the tool spanner of various specifications at every turn, and is more loaded down with trivial details, and has twisted the bolt of a specification, still need change the spanner of another kind of specification, cause the waste in time and look for the loaded down with trivial details of other specification spanners.
SUMMERY OF THE UTILITY MODEL
The purpose of the invention is as follows: an object of the utility model is to provide a can adapt to the little moment of torsion bolt dismouting device of different specification bolts.
The technical scheme is as follows: the utility model discloses a little moment of torsion bolt dismouting device includes first contact plate and second contact plate, threaded rod, first contact plate is fixed in threaded rod one end, and second contact plate is along threaded rod round trip movement, and the one side that first contact plate was kept away from to the second contact plate is equipped with locking device, and the other end of threaded rod is equipped with moment extension bar.
And the center of the second contact plate is provided with a threaded hole matched with the threaded rod, the second contact plate is in threaded connection with the threaded rod, and the second contact plate rotates back and forth on the threaded rod.
Be equipped with the protective sheath on the threaded rod between first contact plate and the second contact plate, the protective sheath can protect the screw thread, prevents to make the screw thread between two contact surfaces take place wearing and tearing at the dismouting in-process.
The protective sheath adopts the rubber material, because rubber has elasticity, can cushion and treat the impact of dismouting bolt to this device.
The outer surface of the protective sleeve is in a polygon prism shape, the contact area between the rubber sleeve and the bolt can be increased by arranging the polygon prism shape, the stable contact between the dismounting device and the bolt is ensured, and the dismounting is convenient.
The threaded rod is in threaded connection with the torque extension rod, and the torque extension rod can save labor in assembly and disassembly.
The locking device is a locking nut, and the locking nut can position the second contact plate.
Has the advantages that: compared with the prior art, the utility model, beneficial effect lies in: (1) the bolt can adapt to bolts with different specifications; (2) the carrying is convenient, the operation is simple, and the structure is light; (3) the arrangement of the moment lengthening rod enables the operation to be more labor-saving.

Detailed Description
The invention will be described in further detail with reference to the following detailed description and the accompanying drawings. As shown in fig. 1, the utility model discloses a small torque bolt dismouting device, including first contact plate 1 and second contact plate 3, threaded rod 5, first contact plate 1 is fixed in threaded rod 5 one end, and second contact plate 3 is along threaded rod 5 round trip movement, and the one side that first contact plate 1 was kept away from to second contact plate 3 is equipped with locking device 4, and in this embodiment, locking device 4 is lock nut. The other end of the threaded rod 5 is in threaded connection with the moment lengthening rod 6. The center of the second contact plate 3 is provided with a threaded hole matched with the threaded rod 5, the second contact plate 3 is in threaded connection with the threaded rod 5, and the second contact plate 3 rotates back and forth on the threaded rod 5.
A protective sleeve 2 is arranged on the threaded rod 5 between the first contact plate 1 and the second contact plate 3.
In this embodiment, protective sheath 2 adopts the rubber material, because rubber has elasticity, can cushion and treat the impact of dismouting bolt to this device. The outer surface of the protective sleeve 2 is in a polygon prism shape, so that the contact area between the rubber sleeve and the bolt can be increased due to the polygon prism shape, the stable contact between the dismounting device and the bolt is ensured, and the dismounting is convenient.
When the torque extension bar is used, the second contact plate 3 is moved towards one end provided with the torque extension bar 6, a bolt cap of a target bolt is placed between the first contact plate 1 and the second contact plate 3, and the top surface of the bolt is attached to the protective sleeve 2; secondly, moving the second contact plate 3 towards the first contact plate 1, and rotating a locknut when the bolt is tightly attached to the two contact plates to fix the second contact plate 3; finally, the torque extension rod 6 is rotated to complete the dismounting work of the target bolt.
