At the same time, the provision of the through slot can play a certain guiding role in the process of excavation of the device, thereby further reducing the obstruction of the mineral.

Description

Technical Field

[0001] The invention relates to the technical field of threaded connecting rods, in particular to screw connecting rods. Background Art

[0002] With the continuous development of industrial modernization, industrial equipment is also undergoing rapid changes. With the replacement of industrial equipment, various equipment are becoming more and more efficient, easier to use, and more and more manpower and material resources are being saved. Among them, as an important raw material and important energy for industrial production, minerals need to be connected with threaded connecting rods during the mining process, thereby extending the length of the connecting rod and facilitating mining.

[0003] In order to prevent mineral locking and drill sticking, people have wrapped steel strips around the outside of existing threaded connecting rods, thereby effectively avoiding the above-mentioned situations and being able to discharge powder well, greatly improving the efficiency of the device. However, although the existing screw connecting rods can achieve the above-mentioned functions, they are suspended and wound around the outside of the rod body during use, so their texture is relatively soft and easy to deform during use. Summary of the invention

[0004] The purpose of the present invention is to provide a screw connecting rod to solve the problem raised in the above background technology that the existing screw connecting rods on the market can achieve the above functions but are relatively soft in texture and easy to deform during use because they are suspended and wound around the outside of the rod body.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a screw connecting rod, comprising a rod body, a male connection, a female connection, a steel belt, a tensioning mechanism and a through groove, wherein a male connection is arranged at the end of the rod body, and a female connection is opened inside the end of the rod body away from the male connection, a steel belt is arranged outside the rod body, a through groove is opened on the outer side of the steel belt, and a tensioning mechanism is fixed between the steel belt and the rod body.

[0006] Preferably, the tensioning mechanism includes a fixing groove, an adjusting nut and a screw rod, wherein there are two fixing grooves in total, and the two fixing grooves are respectively fixed on the rod body and the steel belt, and the two fixing groove openings are opposite to each other, a screw rod is respectively provided at both ends of the adjusting nut, and the threads of the two screw rods are opposite, and the screw rod is threadedly connected to the fixing groove.

[0007] Preferably, a plurality of tensioning mechanisms are provided and are arranged at equal distances on the inner side of the steel belt.

[0008] Preferably, the through grooves are distributed at equal distances on the outside of the steel strip, and the through grooves are parallel to the through groove diameter lines.

[0009] Compared with the prior art, the beneficial effect of the present invention is that the screw connecting rod can adjust the spacing between the steel belt and the rod body by rotating the adjusting nut so that the screw rods at both ends can mesh inside the fixed groove. Since the total length of the steel belt remains unchanged and the total length of the tensioning mechanism changes, the tensioning degree of the steel belt can be adjusted to a certain extent, thereby achieving the purpose of adjusting the tensioning degree and facilitating use. At the same time, the setting of the through groove can play a certain guiding role in the process of excavation of the device, thereby further reducing the obstruction of the mineral.

[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0014] See also Figure 1-2The present invention provides a technical solution: a screw connecting rod, comprising a rod body 1, a male connection 2, a female connection 3, a steel belt 4, a tensioning mechanism 5, and a through groove 6. The end of the rod body 1 is provided with a male connection 2, and the end of the rod body 1 away from the male connection 2 is provided with a female connection 3. The outside of the rod body 1 is provided with a steel belt 4, and the outside of the steel belt 4 is provided with a through groove 6. The through grooves 6 are equidistantly distributed on the outside of the steel belt 4, and the through grooves 6 are parallel to the diameter of the through grooves 6, which can play a certain guiding role in the process of device excavation, thereby further reducing the obstruction of minerals. A tensioning mechanism 5 is fixed between the steel belt 4 and the rod body 1, and the tensioning mechanism 5 includes a fixing groove 501, an adjusting nut 502 and a screw 503. There are two fixing grooves 501 in total, and the two The fixing grooves 501 are fixed on the rod body 1 and the steel belt 4 respectively, and the openings of the two fixing grooves 501 are opposite to each other. A screw rod 503 is respectively arranged at both ends of the adjusting nut 502, and the threads of the two screw rods 503 are opposite, and the screw rod 503 is threadedly connected to the fixing groove 501. There are several tensioning mechanisms 5, which are equidistantly arranged on the inner side of the steel belt 4. The adjusting nut 502 is rotated to make the screw rods 503 at both ends meshingly move inside the fixing groove 501, so as to adjust the distance between the steel belt 4 and the rod body 1. Since the total length of the steel belt 4 remains unchanged, the total length of the tensioning mechanism 5 changes, so the tensioning degree of the steel belt 4 will be adjusted to a certain extent, thereby achieving the purpose of adjusting the tensioning degree, which is convenient for use.

[0015] Working principle: When using the screw connecting rod, first of all, one should have a simple understanding of the structure of the device, and then connect the female connection 3 of one connecting rod with the male connection 2 of another connecting rod to achieve the purpose of extending the length of the device, and then rotate the adjusting nut 502 to make the screws 503 at both ends meshing movement inside the fixed groove 501, so as to adjust the distance between the steel belt 4 and the rod body 1. Since the total length of the steel belt 4 remains unchanged and the total length of the tensioning mechanism 5 changes, the tensioning degree of the steel belt 4 will be adjusted to a certain extent. After the adjustment is completed, the device can be used normally. During use, the opening of the through groove 6 can play a certain guiding role in the process of device excavation, thereby further reducing the obstruction of minerals.
