Description

Technical Field

[0001] This utility model relates to the field of galvanized purlin technology, and in particular to a galvanized purlin that is easy to assemble. Background Technology

[0002] Galvanized purlins are building components made by galvanizing ordinary steel purlins to form a zinc layer on their surface. They are mainly used in roof and wall support systems in building projects to bear the weight of roof and wall materials and transfer the load to the main structure, playing an important role in the stability and safety of buildings.

[0003] The current method of assembling galvanized purlins generally involves pre-drilling multiple sets of holes at the ends of the galvanized purlins and then sequentially tightening multiple sets of bolts to assemble and fix the ends of the two galvanized purlins. However, the traditional method of assembling and fixing galvanized purlins by tightening multiple sets of bolts is cumbersome and not convenient for quickly assembling galvanized purlins. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a galvanized purlin that is easy to assemble, thereby solving the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A type of easy-to-assemble galvanized purlin includes:

[0007] The galvanized purlin body has a protrusion and a slot at each end. One end of the slot on the galvanized purlin body has two second round holes. One end of the protrusion on the galvanized purlin body is inserted into the slot at one end of another galvanized purlin body. Fixing cylinders are fixedly installed on both sides of the inner wall of the galvanized purlin body located on the protrusion.

[0008] Two positioning components are respectively installed in corresponding fixed cylinders. The positioning components can be adjusted by translation and sliding within the fixed cylinders. When the positioning components are respectively inserted into the corresponding second round holes, the two spliced ​​galvanized purlin bodies can be positioned.

[0009] A rotating rod assembly is disposed between two fixed cylinders, and the rotating rod assembly is configured to adjust the translational sliding position of the two positioning components when rotational adjustment is performed.

[0010] Preferably, the galvanized purlin body has two first circular holes at one end of the protrusion.

[0011] Preferably, the inner wall of the fixed cylinder cavity has four sliding grooves, and the four sliding grooves in the fixed cylinder are distributed in a circumferential array.

[0012] Preferably, the positioning component includes:

[0013] An internally threaded cylinder has four rectangular protrusions, which are slidably installed in corresponding grooves inside a fixed cylinder.

[0014] The positioning pin has one end fixedly installed on the inner wall of one end of the internally threaded cylinder, and the other end passes through the first round hole corresponding to the convex end of the galvanized purlin body and is inserted into the second round hole corresponding to the slot end of another galvanized purlin body.

[0015] Preferably, both fixed cylinders have a rotating groove on the side that is close to each other.

[0016] Preferably, the lever assembly includes:

[0017] A bidirectional threaded rod, with its two ends threaded into corresponding internally threaded cylinders.

[0018] The rod disc is fixedly installed in the middle position of the bidirectional threaded rod. Both outer walls of the rod disc have side rings, and the two side rings of the rod disc are respectively rotatably installed in the rotating grooves of two fixed cylinders that are close to each other.

[0019] Preferably, the threads at both ends of the bidirectional threaded rod have opposite directions of rotation, and the threads at both ends of the bidirectional threaded rod are respectively adapted to the internal threads of the corresponding internal threaded cylinders.

[0020] This application involves inserting one end of the protrusion on one galvanized purlin body into a slot at one end of another galvanized purlin body. Then, by turning the rotating disc, the bidirectional threaded rod rotates, causing two internally threaded cylinders to slide synchronously within their corresponding fixed cylinders and move away from each other. This, in turn, causes the positioning pins on the two internally threaded cylinders to move outward synchronously until the two positioning pins are inserted into the corresponding second round holes at one end of the slot of the assembled galvanized purlin body. This achieves positioning of the two assembled galvanized purlin bodies, enabling rapid assembly. When the rotating disc on the bidirectional threaded rod is turned in the opposite direction, the bidirectional threaded rod rotates in the opposite direction, causing the two positioning pins to retract into the corresponding first round holes of the galvanized purlin bodies, thus allowing the two galvanized purlin bodies to be disassembled and separated. This application allows for rapid installation or disassembly of two galvanized purlin bodies, with simple and quick operation. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] To address the problem that traditional galvanized purlin assembly involves cumbersome installation and disassembly processes using multiple sets of bolts, hindering rapid assembly, this embodiment discloses a galvanized purlin design that facilitates assembly. Figure 2 As shown, it includes: a galvanized purlin body 100, two positioning assemblies 200 and a rotating rod assembly 300.

[0031] like Figure 1 As shown, to facilitate the assembly of two galvanized purlin bodies 100, each galvanized purlin body 100 has a protrusion 101 and a slot 102 at both ends. One end of the protrusion 101 on the galvanized purlin body 100 is inserted into the slot 102 at one end of the other galvanized purlin body 100.

[0032] like Figure 6As shown, in order to install two positioning components 200, a fixing cylinder 103 is fixedly installed on both sides of the inner wall of the galvanized purlin body 100 at the protrusion 101. The inner wall of the cylinder cavity of the fixing cylinder 103 has four sliding grooves 1031, which are rectangular in structure and arranged in a circular array. The two positioning components 200 are respectively installed in the corresponding fixing cylinders 103, and the positioning components 200 can be adjusted by translation and sliding within the fixing cylinders 103. The positioning component 200 includes: an internal threaded cylinder 201 and a positioning post 202. The internal threaded cylinder 201 has four rectangular protrusions 2011. 2011 are slidably installed in corresponding grooves 1031 inside the fixed cylinder 103; at the same time, one end of the slot 102 on the galvanized purlin body 100 has two second round holes 1021; the galvanized purlin body 100 has two first round holes 1011 at one end of the protrusion 101; one end of the positioning post 202 is fixedly installed on the inner wall of one end of the internal threaded cylinder 201, and the other end passes through the corresponding first round hole 1011 on the galvanized purlin body 100 at the protrusion 101 and is inserted into the corresponding second round hole 1021 at one end of the slot 102 of another galvanized purlin body 100, thereby positioning the two spliced ​​galvanized purlin bodies 100.

[0033] Continue as Figure 6 As shown, for the installation of the rotating rod assembly 300, each of the two fixed cylinders 103 has a rotating groove 1032 on one side close to each other, and the rotating rod assembly 300 is disposed in the rotating groove 1032 between the two fixed cylinders 103; the rotating rod assembly 300 is configured to adjust the translational sliding position of the two positioning components 200 when rotational adjustment is performed; the rotating rod assembly 300 includes: a bidirectional threaded rod 301 and a rod disc 302; the two ends of the bidirectional threaded rod 301 are respectively threaded into the corresponding internal threaded cylinders 201, the threads at the two ends of the bidirectional threaded rod 301 have opposite directions of rotation, and the threads at the two ends of the bidirectional threaded rod 301 are respectively adapted to the internal threads of the corresponding internal threaded cylinders 201; the rod disc 302 is fixedly installed in the middle position of the bidirectional threaded rod 301, and the two outer walls of the rod disc 302 each have a side ring 3021, and the two side rings 3021 of the rod disc 302 are respectively rotatably installed in the rotating groove 1032 close to each other of the two fixed cylinders 103.

[0034] This application involves inserting one end of the protrusion 101 on one galvanized purlin body 100 into a slot 102 at one end of another galvanized purlin body 100. Then, by rotating the rotating rod disc 302, the bidirectional threaded rod 301 is rotated, causing the two internally threaded cylinders 201 to slide synchronously within their corresponding fixed cylinders 103 and move away from each other. This, in turn, causes the positioning pins 202 on the two internally threaded cylinders 201 to move outward synchronously until the two positioning pins 202 are respectively inserted into the corresponding second round holes at one end of the slot 102 of the other galvanized purlin body 100 after splicing. Within 1021, the two spliced ​​galvanized purlin bodies 100 are positioned, enabling rapid assembly of the two galvanized purlin bodies 100. When the rod disc 302 on the bidirectional threaded rod 301 is turned in the opposite direction, the bidirectional threaded rod 301 is rotated in the opposite direction, allowing the two positioning pins 202 to be retracted into the corresponding first circular holes 1011 of the galvanized purlin bodies 100, thereby allowing the two galvanized purlin bodies 100 to be disassembled and separated. In this application, the installation or disassembly of the two galvanized purlin bodies 100 can be quickly realized, and the operation is simple and fast.
