Description

Technical Field

[0001] The utility model relates to the field of graphite screws, and more specifically to a graphite screw with high efficiency and stability. Background Art

[0002] Graphite screw is a screw made of graphite material. Graphite screw has an extremely high melting point, so it can run stably for a long time in a high temperature environment. This characteristic makes graphite screw widely used in industries that require high temperature processing, such as metallurgy, glass, and ceramics. In the above industries, graphite screws are used as core components of equipment such as agitators, heaters, and conveyors to ensure the normal operation of the equipment at high temperatures.

[0003] Existing graphite screws are usually connected to the connected parts through their threads. However, due to the limited actual contact area between the screw and the connected parts, the connection between the screw and the connected parts may not be stable enough. This instability may cause the connection to loosen or slip when subjected to heavy loads or vibrations. This will not only affect the normal operation of the equipment, but may also cause safety accidents. In addition, the length of ordinary screws is usually fixed, which means that they can only meet the connection requirements within a specific length range. In some specific application scenarios, they may not meet the requirements. If screws need to be used at connection points of different lengths, it is necessary to prepare screws of multiple different lengths, which increases costs. Utility Model Content

[0005] In order to achieve the above-mentioned objectives, the utility model provides the following technical solutions: a graphite screw, comprising a first stud, a first connecting rod fixedly connected to the first stud, an insertion rod fixedly connected to the first connecting rod, a second connecting rod fixedly connected to the insertion rod, and a second stud connected to the second connecting rod, the first stud having a first nut, the second stud having a second nut, the insertion rod and the first connecting rod being fixedly connected by a fixing bolt and a fixing member, the first connecting rod having an insertion channel that cooperates with the insertion rod, the fixing member comprising a nut and a sleeve connected to the nut, the sleeve having an internal thread that cooperates with the fixing bolt, the first connecting rod having a first through hole that cooperates with the sleeve and passes through the first connecting rod, the insertion rod having a plurality of second through holes that cooperate with the sleeve, the plurality of second through holes being distributed in a row with equal spacing, a plurality of sleeve blocks that are sleeved on the outside of the insertion rod are provided between the first connecting rod and the second connecting rod, the sleeve blocks having a circular through hole that cooperates with the insertion rod.

[0006] Furthermore, the cross-sections of the first connecting rod, the second connecting rod and the sleeve block are all rectangular and have the same shape and size, and the first stud and the second stud have the same shape and size.

[0007] Therefore, the connection between the sleeve block and the first connecting rod and the second connecting rod is more stable.

[0008] Furthermore, the first connecting rod and the second connecting rod are provided with cylindrical pads, and the pads are provided with rectangular slots matched with the first connecting rod and threaded holes matched with the first studs.

[0009] Thereby, the contact surface between the cushion block and the connected member can be made larger, so that the connection is more stable.

[0010] Furthermore, the diameters of the insertion channel, the circular through hole and the insertion rod are equal.

[0011] Therefore, the insertion rod is firmly connected to the sleeve block and the first connecting rod.

[0012] Furthermore, there are two fixing members and two fixing bolts, and the first connecting rod is provided with two first through holes.

[0013] Thereby, the connection stability between the first connecting rod and the insertion rod is further enhanced.

[0014] Furthermore, the number of the second perforations is greater than or equal to 4.

[0015] Thus, the adjustment range of the total length of the screw is large.

[0016] Furthermore, the first stud, the second stud, the first connecting rod, the insert rod, the second connecting rod, the fixing piece, the fixing bolt, the first nut, the second nut, the sleeve block, and the spacer block are all made of graphite material.

[0017] So it can be used in high temperature environment.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] 1. The total length of the graphite screw of the present application can be adjusted according to needs, and the adjustment operation is simple and quick, so that the graphite screw can adapt to different working scenarios and needs.

[0020] 2. The graphite screw of the present application has a cushion block, so that the contact area between the cushion block and the connected part is large, so that the connection is more stable.

[0021] 3. The number of sleeves of the graphite screw of the present application is optional. After the length is adjusted, the sleeve is wrapped around the rod to increase the overall strength, so that the screw can still maintain stable performance after adjustment.

[0022] 4. The graphite screw of the present application has all components made of graphite material, so it can be used in a high temperature environment and has a long service life. BRIEF DESCRIPTION OF THE DRAWINGS
