Description

Easy-to-draw locking bolt

Technical Field

The utility model relates to a rope connecting device, in particular to an easy-to-pull locking bolt.

Background

The wire rope can use basket of flowers bolt often in the process of continuing, and basket of flowers bolt connects wire rope respectively through the ring and the couple at both ends to can utilize the lead screw to stretch out and draw back, adjust wire rope's elasticity, but it is when connecting wire rope, need make the lasso with bundle silk or wire card earlier, supply ring or couple tensile, whole process needs manual locking, and this kind of mode not only operates more troublesome, and is more laborious moreover.

In order to solve the above problems, people are always seeking an ideal technical solution.

Disclosure of Invention

The utility model aims to overcome the defects of the prior art, and provides the easy-to-pull locking bolt which is simple in structure, convenient to operate, time-saving, labor-saving and high in practicability.

In order to achieve the purpose, the utility model adopts the technical scheme that: the utility model provides an easy-to-draw locking bolt, includes one set at least retaining member, every set the retaining member all includes the body of rod, sets up two stringing holes and two pairs of clamp nut on the body of rod, the body of rod surface be provided with clamp nut mutually supported's external screw thread, two pairs clamp nut and two stringing hole one-to-one sets up, with two to clamp nut is located respectively stringing hole both sides.

Based on the above, at least one clamping nut in each pair of clamping nuts is welded with a handle.

Based on the above, each clamping nut is provided with a washer on the inner side.

Based on the above, the novel telescopic rod further comprises a hollow connector, the locking pieces are provided with two sets, the locking pieces are opposite to each other, the middle cross section of the hollow connector is symmetrically arranged, the two ends of the hollow connector correspond to the two rod bodies, threaded holes are formed in the two rod bodies respectively, and the thread directions of the threaded holes are opposite.

Based on the above, be provided with the viewing aperture on the hollow connector.

Compared with the prior art, the utility model has substantive characteristics and progress, concretely, when the utility model is used, the steel wire rope can pass through one rope passing hole, or pass through another rope passing hole after passing through one rope passing hole, and then the steel wire rope can be clamped through the rotation of the two clamping nuts, so as to realize locking, especially when passing through the two rope passing holes, the steel wire rope forms a bend, so that the clamping is very firm, compared with the traditional turn buckle, the utility model omits the step of making the steel wire rope into a ferrule and tensioning, thereby greatly improving the installation efficiency, and having the advantages of simple structure, convenient operation, time saving, labor saving and strong practicability.

Furthermore, the handle can conveniently rotate the clamping nut, and the clamping nut can be screwed without using a spanner; the arrangement of the gasket increases the contact area with the steel wire rope, reduces the local pressure and prolongs the service life of the device.

Furthermore, the two locking pieces are symmetrically arranged, so that the directions of external threads of the two rod bodies are just opposite, threaded holes matched with the two rod bodies are formed in the two ends of the hollow connecting body, and when the steel wire rope fixing device is used, the two rod bodies can move oppositely or oppositely only by rotating the hollow connecting body, so that the length of the steel wire rope is adjusted; the setting of viewing aperture conveniently observes two the interval of the body of rod to conveniently judge the regulating variable.

In the figure: 1. a rod body; 2. a stringing hole; 3. clamping the nut; 4. a handle; 5. a gasket; 6. a hollow connector; 7. a viewing port.

Detailed Description

The technical solution of the present invention is further described in detail by the following embodiments.

Example 1

As shown in fig. 1, an easy-to-draw locking bolt comprises a locking member, wherein the locking member comprises a rod body 1, two rope penetrating holes 2 and two pairs of clamping nuts 3, the two rope penetrating holes 2 and the two pairs of clamping nuts 3 are formed in the rod body 1, external threads matched with the clamping nuts 3 are arranged on the surface of the rod body 1, the two pairs of clamping nuts 3 and the two rope penetrating holes 2 are arranged in a one-to-one correspondence mode, and the two clamping nuts 3 are located on two sides of the rope penetrating holes 2 respectively.

The working principle is as follows:

the steel wire rope penetrates through one rope penetrating hole 2 or penetrates through one rope penetrating hole 2 and then penetrates through the other rope penetrating hole 2, the steel wire rope can be clamped through rotation of the two clamping nuts 3, locking is achieved, particularly when the steel wire rope penetrates through the two rope penetrating holes, the steel wire rope is bent, clamping is firm, and compared with a turnbuckle, operation convenience is greatly improved.

In order to facilitate the operation, at least one clamping nut 3 in each pair of clamping nuts 3 is welded with a handle 4; this eliminates the need for an additional wrench to screw the clamping nut 3.

In order to prolong the service life, a washer 5 is arranged on the inner side of each clamping nut 3; when the pressure-resistant steel wire rope clamp is used, the contact area between the gasket 5 and a steel wire rope is increased, the local pressure is reduced, and the probability of damage is reduced.

Example 2

As shown in fig. 2, the difference between this embodiment and embodiment 1 is that the easy-to-draw locking bolt further includes a hollow connector 6, two sets of locking members are provided, the two sets of locking members are symmetrically provided with respect to the middle cross section of the hollow connector 6, two ends of the hollow connector 6 are respectively provided with threaded holes corresponding to the two rod bodies 1, and the thread directions of the two threaded holes are opposite; two sets retaining member symmetry sets up, two like this the external screw thread direction of the body of rod 1 is just in time also opposite, during the use, only needs to rotate cavity connector 6, two the body of rod 1 just can be relative or back of the body of rod motion mutually, realizes the regulation to wire rope length.

In order to observe the adjustment amount conveniently, the hollow connecting body 6 is provided with an observation port 7, so that the distance between the two rod bodies 1 can be seen in the adjustment process.

Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present invention and not to limit the same; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will understand that: modifications to the specific embodiments of the utility model or equivalent substitutions for parts of the technical features may be made; without departing from the spirit of the present invention, it is intended to cover all aspects of the utility model as defined by the appended claims.
