Abstract
Description
Technical Field
[0001] This utility model belongs to the field of screw technology, and more specifically, it relates to an assembled screw. Background Technology
[0002] A screw is a cylindrical mechanical component with helical grooves, its outer surface cut with helical channels. Screws possess properties such as high temperature resistance, wear resistance, corrosion resistance, and high strength, making them excellent in a variety of applications. In plastic molding equipment, screws are core components of injection molding machines and extruders, used for conveying, melting, and injection molding of plastics. Furthermore, screws are widely used in material handling, lifting equipment, automatic door drives, air compressors, and other fields. In shipbuilding, propellers, as the main power plant of modern ships, also rely heavily on screws.
[0003] Based on the above, the inventors have discovered the following problems: most screws are now integrally molded, and different lengths of screws may be used during operation, so different lengths of screws need to be purchased, resulting in high operating costs.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an assembled screw to achieve a more practical purpose. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides an assembled screw to solve the problem of high operating costs caused by the inability to adjust existing screws.
[0006] The purpose and effect of this utility model of an assembled screw are achieved by the following specific technical means:
[0007] An assembled screw includes a screw body, of which there are multiple screw bodies. A first limiting block is installed at one end of each screw body, and a first limiting groove is formed at the end of each screw body away from the first limiting block. The first limiting block on one screw body is located in the first limiting groove on another screw body, and the first limiting block and the first limiting groove are matched. A first connecting member is installed at one end of one screw body located on the outer side, and a second connecting rod is installed at one end of another screw body located on the outer side. A second limiting groove is formed at the end of the first connecting member that contacts the screw body, and a second limiting block is installed at the end of the second connecting rod that contacts the screw body. The screw body also includes a limiting rod that penetrates through the screw body, and both ends of the limiting rod extend into the interior of the first connecting member and the second connecting rod, respectively. Limiting holes are formed on the surfaces of the screw body, the first connecting member, and the second connecting rod. The first connecting member and the second connecting rod are connected to the limiting rod by a fixing mechanism.
[0008] Furthermore, the fixing mechanism includes a threaded hole and a bolt. The threaded hole is located on the surface of one end of the limiting rod, and the bolt passes through the first connecting member and rotates into the threaded hole.
[0009] Furthermore, both the screw body and the limiting rod have different lengths.
[0010] Furthermore, the first limiting block, the first limiting groove, the second limiting groove, and the second limiting block are all square.
[0011] Furthermore, the screw body, the first connecting member, the second connecting rod, and the limiting rod are all made of metal.
[0012] Furthermore, the metal material is alloy steel.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] This utility model utilizes the combined use of a screw body, a first limiting block, a first limiting groove, a first connecting member, a second connecting rod, a second limiting groove, a second limiting block, a limiting rod, a protrusion, a limiting hole, and a fixing mechanism. When a screw is needed, simply select a limiting rod of appropriate length and multiple screw bodies matching the length of the limiting rod. Then, insert the limiting rod into the limiting hole on the surface of the first connecting member, and fix the limiting rod and the first connecting member with bolts. Next, sleeve the screw body onto the limiting rod, insert the first limiting block on the screw body into the second limiting groove on the surface of the first connecting member, and then... The first limiting block on the surface of the rod body is aligned with the first limiting groove on the previous screw body and installed until the screw body is installed. Then, the second limiting block on the second connecting rod is aligned with the first limiting groove on the last screw body and installed. Finally, it is fixed with bolts to complete the screw assembly. It should be noted that the length of the limiting rod is slightly less than the length of the limiting hole. This allows for a tighter connection between the connecting parts when the bolts are tightened. With the above design, only limiting rods of different lengths and multiple screw bodies need to be prepared, which is more cost-effective than purchasing multiple screws of different lengths.

[0025] Example:
[0026] As attached Figure 1 To be continued Figure 5 As shown:
[0027] This utility model provides an assembled screw, including a screw body 1, of which there are multiple screw bodies 1. A first limiting block 2 is installed at one end of each screw body 1, and a first limiting groove 3 is formed at the end of each screw body 1 away from the first limiting block 2. The first limiting block 2 on one screw body 1 is located within the first limiting groove 3 on another screw body 1, and the first limiting block 2 and the first limiting groove 3 are matched. A first connecting piece 4 is installed at one end of one screw body 1 located on the outer side, and a second connecting piece 4 is installed at one end of another screw body 1 located on the outer side. The connecting rod 5 has a second limiting groove 6 at one end of the first connecting member 4 that contacts the screw body 1, and a second limiting block 7 is installed at one end of the second connecting rod 5 that contacts the screw body 1. It also includes a limiting rod 8, which passes through the screw body 1 and extends to the interior of the first connecting member 4 and the second connecting rod 5 respectively. Limiting holes 10 are opened on the surfaces of the screw body 1, the first connecting member 4 and the second connecting rod 5. The first connecting member 4 and the second connecting rod 5 are connected to the limiting rod 8 through a fixing mechanism 11.
[0028] The fixing mechanism 11 includes a threaded hole 1101 and a bolt 1102. The threaded hole 1101 is located on the surface of one end of the limiting rod 8, and the bolt 1102 passes through the first connecting member 4 and rotates into the threaded hole 1101.
[0029] The limiting rod 8 has different lengths.
[0030] By using the screw body 1, first limiting block 2, first limiting groove 3, first connecting piece 4, second connecting rod 5, second limiting groove 6, second limiting block 7, limiting rod 8, protrusion 9, limiting hole 10, and fixing mechanism 11 in conjunction, when a screw is needed, simply select a limiting rod 8 of appropriate length and multiple screw bodies 1 matching the length of the limiting rod 8. Then, insert the limiting rod 8 into the limiting hole 10 on the surface of the first connecting piece 4, and fix the limiting rod 8 and the first connecting piece 4 with bolts 1102. Then, sleeve the screw body 1 onto the limiting rod 8, insert the first limiting block 2 on the screw body 1 into the second limiting groove 6 on the surface of the first connecting piece 4, and then... The first limiting block 2 on the surface of one screw body 1 is aligned with the first limiting groove 3 on the previous screw body 1 and installed until the screw body 1 is installed. Then, the second limiting block 7 on the second connecting rod 5 is aligned with the first limiting groove 3 on the last screw body 1 and installed. Finally, it is fixed with bolts 1102 to complete the screw assembly. It should be noted that the length of the limiting rod 8 is slightly less than the length of the limiting hole 10. This allows for a tighter connection between the connecting parts when the bolts 1102 are tightened. With the above design, only limiting rods 8 of different lengths and multiple screw bodies 1 need to be prepared, which is more cost-effective than purchasing multiple screws of different lengths.
[0031] The first limiting block 2, the first limiting groove 3, the second limiting groove 6, and the second limiting block 7 are all square. This design effectively limits movement.
[0032] The screw body 1, the first connecting piece 4, the second connecting rod 5, and the limiting rod 8 are all made of metal.
[0033] The metal material is alloy steel.
[0034] The use of alloy steel can extend its service life.
