Description

Four-section stone reaming screw for forced-fixing device

This creation provides a four-section stone reaming screw for a solid-fixing device, especially an innovative structural designer used for fixing functions such as stone or RC concrete blocks.

According to the sixth and seventh figures, a threaded rod 1 is provided with a sleeve 2 which is formed by two identical shapes and opposite. The clamping block 21 is provided with an outwardly extending gear body 221, and the clamping block 21 is provided with a thread 22 on the opposite side, and the thread 22 can be screwed with the thread on the threaded rod 1 In use, the clamping block 21 is respectively embedded in the predetermined hole 31 of the object 3, and the threaded rod 1 is put between the clamping blocks 21, so that the thread 22 on the clamping block 21 can be screwed with the thread on the threaded rod 1. In the same manner, the clamping block 21 is gradually expanded outwardly under the pressing of the threaded rod 1, and the outwardly extending body 221 is fastened to the wall surface of the hole 31, so that the clamping block 21 is fixed in the hole 31. After the threaded rod 1 is exposed at one end of the sleeve 2 and is inserted into the through hole 42 of the fixing member 4, a nut 5 is screwed onto the threaded rod 1, so that the sleeve 2 can be The retaining body 221 is supported by the object member 3 so as not to fall off, so that the object member 3 can be hung on the object combined with the fixing member 4; however, the sleeve 2 is separated into two pieces separately. The sheet body, so if the volume of the object 3 is bulky, it often happens that the outwardly expanding end of the sleeve 2 cannot bear the weight of the object 3, and then the object 3 is removed, causing the object 3 to fall from the fixed place. use Not very ideal.

The creator has the above-mentioned tamping device for the use of stone materials, etc., and there is indeed a significant lack of implementation in the implementation of the fixed, especially for its many years of practical experience in the production of related products, it has always adhered to the excellent design concept, The lack of improvement makes it possible to make the fixing device of the stone or RC concrete block more suitable for the improvement of the implementation.

The creator of the present invention has the following advantages: the sleeve is a hollow tubular body, and the tubular portion is outwardly presented. The tapered opening and the opening portion which gradually expands outward, and the surface of the tubular portion from the surface of the opening portion to the surface of the opening portion is provided with a type of slit formed by a four-ring array, and the opening portion of the sleeve is formed into four pieces. In the implementation, the threaded rod is sleeved in the sleeve portion and the opening portion of the sleeve, and the sleeve is urged outwardly under the pressure of the threaded rod, thereby achieving the sleeve The person who is fixed in the object.

The spirit and the embodiments of the present invention will be explained in the following description and the detailed description, and those skilled in the art will be able to change the technology disclosed by the present invention after understanding the preferred embodiment of the present invention. Modifications do not depart from the spirit and scope of this creation.

Please refer to the first, second and third figures. The four-section stone reaming screw of the urging device of the present invention is provided with a threaded rod 6 which is screwed with a nut 7 at one end and a fixing member 8 at the other end. The hole 81 and the sleeve 9 are screwed together to form a common body; wherein the sleeve 9 is a hollow tube body, and a hexagonal flange 91 is arranged adjacent to one end of the fixing member 8 The tubular portion 92 having a tapered shape is formed with an opening portion 93 which is gradually enlarged outward, and a surface of the portion of the tubular portion 92 from the surface of the opening portion 93 is formed by a four-ring array of slits 94. The opening portion 93 of the sleeve 9 is caused to form a four-piece clamp 95.

Referring to the fourth and fifth figures, in the implementation, the threaded rod 6 is sleeved in the cylindrical portion 92 of the sleeve 9 and the opening portion 93, and the sleeve 9 is urged under the pressure of the threaded rod 6 to promote the clamping block. 95 is outwardly expanded to achieve the purpose of securing the sleeve 9 to the article 3 in a timely manner.
