Detailed Description

Embodiment 1 this implementation provides a stagnant water accessory for screw rod is dismantled, including inner tube 2 and thread bush 1, and inner tube 2 is the hollow barrel that has certain length, and every portion of barrel is equipped with the axial through-hole 205 that runs through the barrel both ends, and the aperture of axial through-hole 205 slightly is greater than the end screw rod of syllogic stagnant water screw rod. One end of the inner cylinder 2 is provided with a connecting external thread 201 which is matched with the thread bush 1; the other end of inner tube 2 is location end 202, and 2 ~ 4 radial location trompils 204 that set up are seted up to the tip of location end 202, and location trompil 204 is the screw hole best, and threaded connection has the cooperation of location plug screw in the screw hole.

Of course, the positioning holes 204 are preferably disposed on the same radial plane, which is convenient for processing and can ensure the positioning effect of the water stop screw rod. In addition, the wall thickness of the positioning end 202 of the inner cylinder 2 and the wall thickness near the positioning end are preferably larger than those of other parts, so that the situation that the positioning hole is formed to cause weak structure is avoided.

The threaded sleeve 1 is a strip-shaped object with a certain length, and one end of the threaded sleeve is provided with a connecting inner screw hole 101 and is in threaded fit with a connecting outer screw thread 201, so that the threaded sleeve 1 and one end of the inner cylinder 2 are fixed in a rotating mode. The other end of the threaded sleeve 1 is provided with a drill groove 102 matched with a connector of an electric drill, and in the embodiment, the drill groove 102 is a square groove. The rotation direction of the thread between the threaded sleeve 1 and the inner cylinder 2 is opposite to the rotation direction of the electric drill. Meanwhile, the end of the inner cylinder 2 is provided with an extension slot 203 which can expand or reduce the diameter of the port of the inner cylinder 2 in a small range. In order to prevent the water stop screw from penetrating out of the threaded sleeve 1, the drill groove 102 in the threaded sleeve 1 is not communicated with the end, provided with the connecting internal thread, of the threaded sleeve 1.

The extension slot 203 of the present embodiment has two functions: firstly, considering that the water-stopping screw rod needs to be conveniently inserted into the inner cylinder 2 in a specific use process, the aperture of the axial through hole 205 needs to be slightly larger than the rod diameter of the water-stopping screw rod, so that the side opening can be contracted through the matching of the threaded inner screw hole and the external connecting thread, and the water-stopping screw rod is fixed with the end of the inner cylinder 2; secondly, in the actual use process, because the circumstances such as rust and producer difference, the rod footpath of the end screw portion of stagnant water screw rod is not the fixed value, has certain floating, for example usually is 0.7 ~ 1.2cm, can take median 1cm as the aperture of axial through-hole 205 in this embodiment. In order to meet the actual use requirements, the aperture of the axial through hole 205 needs to be slightly larger than the rod diameter of the water stop screw, and the water stop screw can adapt to different water stop screws in a smaller floating range. Meanwhile, the extension slot 203 is arranged at the threaded connection part, so that the opening is convenient to tighten, and the water stop screw is fastened in the inner barrel 2.

The application process of the embodiment is as follows: the inner cylinder 2 is firstly sleeved on the water stopping screw rod, the end part of the water stopping screw rod is slightly exposed out of one end of the inner cylinder 2 provided with the connecting external thread 201, and the end of the sleeve provided with the connecting internal thread hole 101 is in threaded connection with the inner cylinder 2, so that the inner cylinder 2 is preliminarily fastened by the matching of the extension slot 203 and the sleeve. The positioning screw pin in the positioning hole 204 is then tightened, so that the positioning end 202 of the inner cylinder 2 is also fastened with at least the screw rod. After the operation is finished, a connector of an electric drill is inserted into the drill groove 102, and the electric drill works to drive the disassembling accessory to rotate and drive the water stopping screw rod clamped in the inner cylinder 2 to rotate, so that the end screw rod is separated from the middle screw rod.

Through the structure, the end screw rod of electronic dismantlement stagnant water screw rod is realized to this embodiment, has effectively improved the efficiency that stagnant water screw rod demolishd, and the dismantlement process is laborsaving convenient again to be favorable to shortening construction cycle.

Embodiment 2 on the basis of the embodiment, an inner hole 103 with a diameter slightly larger than the rod diameter of the water stop screw rod is further arranged in the middle of the threaded sleeve 1, and the inner hole 103 is communicated with a connecting inner screw hole 101 at one end of the threaded sleeve 1.

In the above embodiment, further consider that the length of stagnant water screw rod is longer, if the length of dismantling with the accessory is not enough, can only act on the outer end of stagnant water screw rod and near, the length L1 of inner tube 2 is not less than 10cm, best is in the intermediate position of stagnant water screw rod when making the dismantlement with the cooperation of stagnant water screw rod, considers low-cost and laborsaving dismantlement two aspects, ensures the practicality. In example 2, the length of the inner hole 103L2 is not less than 5 cm.

The structure of the drill slot 102 may be other polygonal recesses such as a triangular recess and a hexagonal recess, in addition to the directional recess described in embodiment 1.

To sum up, the utility model provides a can turn into the accessory for dismantlement of electronic dismantlement with manual dismantlement, its and stagnant water screw rod adaptation can effectively improve dismantlement speed and efficiency, and then make stagnant water screw rod convenient to detach and retrieve.
