Description

Technical Field

[0001] This utility model relates to an easy-to-assemble stainless steel square tube, belonging to the technical field of stainless steel square tubes. Background Technology

[0002] Stainless steel square tubing is a type of highly corrosion-resistant metal tubing, typically made of stainless steel alloy. It possesses strong resistance to oxidation, high temperatures, and corrosion, and is widely used in construction, machinery, and chemical industries. Its square shape and smooth, flat surface allow it to withstand significant pressure and maintain a long service life. Common stainless steel square tubing comes in various specifications and can be customized to meet specific needs, offering both aesthetic appeal and practicality.

[0003] In the existing technology, it is inconvenient to assemble stainless steel square tubes. The difficulty in assembly means that more time and manpower are needed for splicing and installation, which increases construction costs and time, reduces project efficiency, and may require more maintenance and inspection, especially when disassembly or adjustment is required, which may result in greater workload and cost, thereby reducing work efficiency.

[0004] Therefore, a stainless steel square tube that is easy to assemble is proposed. Utility Model Content

[0005] In view of this, the present invention provides an easy-to-assemble stainless steel square tube to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial alternative.

[0006] The technical solution of this utility model is implemented as follows: an easy-to-assemble stainless steel square tube, including a first square tube and a second square tube, the first square tube and the second square tube are made of the same material, a slot is provided on the right side of the second square tube, a slot is provided on the top of the second square tube, a plug-in block is fixedly connected to the left side of the first square tube, a spring is fixedly connected to the bottom of the inner cavity of the plug-in block, a movable block is fixedly connected to the top of the spring, a locking block is fixedly connected to the top of the movable block, and the locking block penetrates and extends to the top of the plug-in block, and the locking block is engaged in the slot.

[0007] More preferably, the first square tube includes a base layer, a first functional layer and a second functional layer, the first functional layer includes a ceramic layer and a polytetrafluoroethylene layer, and the second functional layer includes a polyurethane coating and an epoxy resin coating.

[0008] More preferably, the first functional layer is disposed on the outer surface of the substrate layer, and the second functional layer is disposed on the outer surface of the first functional layer.

[0009] More preferably, the ceramic layer is disposed on the outer surface of the substrate layer, and the polytetrafluoroethylene layer is disposed on the outer surface of the ceramic layer.

[0010] More preferably, the polyurethane coating is disposed on the outer surface of the polytetrafluoroethylene layer, and the epoxy resin coating is disposed on the outer surface of the polyurethane coating.

[0011] More preferably, the inner wall of the plug block is provided with sliding grooves on both the front and rear sides, and the movable block is fixedly connected to the front and rear sides, with the sliding sliders slidably connected in the sliding grooves.

[0012] The present invention has the following advantages due to the adoption of the above technical solution:

[0013] I. This utility model uses a downward pressing mechanism to move a movable block downwards. The movable block compresses a spring, causing it to deform under the influence of force. Simultaneously, the locking block retracts into the insertion block, which is then inserted into the slot. When the insertion block enters the slot and the locking block moves to a position parallel to the slot, the spring deforms again due to the loss of force, causing the locking block to spring upwards and engage with the slot, thus completing the rapid assembly of the first square tube and the second square tube, thereby improving work efficiency.

[0014] II. This utility model incorporates a first functional layer comprising a ceramic layer and a polytetrafluoroethylene (PTFE) layer. The ceramic layer effectively prevents corrosive liquids or gases from eroding the first square tube, exhibiting excellent performance, especially in acidic or alkaline environments, thereby extending the overall service life. The PTFE layer possesses excellent chemical corrosion resistance, resisting corrosion from most acids, alkalis, and solvents. It forms a dense protective film on the surface of the first square tube, preventing damage from chemical media and making it suitable for more demanding chemical environments.

[0015] Third, this utility model incorporates a second functional layer comprising a polyurethane coating and an epoxy resin coating. The polyurethane coating possesses excellent wear resistance and impact resistance, making it suitable for outer layer protection. It effectively resists external physical damage, preventing wear during transportation, installation, or external impacts, thereby increasing mechanical strength and surface protection. The epoxy resin coating prevents chemical corrosion in the external environment from damaging the first square tube. Its high adhesion and excellent durability ensure effective protection of the first square tube in various environments.

[0025] In the following description, only certain exemplary embodiments are briefly described.

Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] Example 1

[0028] like Figure 1-6As shown, this utility model embodiment provides an easily assembled stainless steel square tube, including a first square tube 1 and a second square tube 2. The first square tube 1 and the second square tube 2 are made of the same material. A slot 5 is provided on the right side of the second square tube 2, and a slot 4 is provided on the top of the second square tube 2. A plug-in block 6 is fixedly connected to the left side of the first square tube 1. A spring 7 is fixedly connected to the bottom of the inner cavity of the plug-in block 6. A movable block 8 is fixedly connected to the top of the spring 7. A locking block 3 is fixedly connected to the top of the movable block 8, and the locking block 3 penetrates and extends to the top of the plug-in block 6. The locking block 3 is engaged in the slot 4. Sliding grooves 10 are provided on both the front and rear sides of the inner wall of the plug-in block 6. Sliding blocks 9 are fixedly connected to both the front and rear sides of the movable block 8, and the sliding blocks 9 are slidably connected in the sliding grooves 10.

[0029] By pressing down on the locking block 3, the movable block 8 moves downward. The movable block 8 compresses the spring 7, causing it to deform due to the force. At the same time, the locking block 3 retracts into the insertion block 6. Then, the insertion block 6 is inserted into the slot 5. When the insertion block 6 enters the slot 5 and the locking block 3 moves to a parallel position with the slot 4, the spring 7 deforms again due to the loss of force and causes the locking block 3 to spring upward and engage with the slot 4, thus completing the rapid assembly of the first square tube 1 and the second square tube 2, thereby improving work efficiency.

[0030] Example 2

[0031] In one embodiment, the first square tube 1 includes a base layer 11, a first functional layer 12, and a second functional layer 13. The first functional layer 12 includes a ceramic layer 1201 and a polytetrafluoroethylene layer 1202.

[0032] By setting a first functional layer 12 including a ceramic layer 1201 and a polytetrafluoroethylene layer 1202, the ceramic layer 1201 effectively prevents corrosive liquids or gases from eroding the first square tube 1, especially performing well in acidic or alkaline environments, thereby extending the overall service life. The polytetrafluoroethylene layer 1202 has excellent chemical corrosion resistance, resisting corrosion from most acids, alkalis and solvents, and can form a dense protective film on the surface of the first square tube 1 to prevent chemical media from harming it, making it suitable for more demanding chemical environments.

The epoxy resin coating 1302 can prevent chemical corrosion in the external environment from damaging the first square tube 1. Its high adhesion and excellent durability ensure that the first square tube 1 can be effectively protected in various environments.

[0033] In operation, this invention works as follows: pressing down on the locking block 3 moves the movable block 8 downwards. The movable block 8 compresses the spring 7, causing it to deform under the force. Simultaneously, the locking block 3 retracts into the insertion block 6, which is then inserted into the slot 5. When the insertion block 6 enters the slot 5 and the locking block 3 moves to a parallel position with the slot 4, the spring 7 deforms again due to the loss of force, causing the locking block 3 to spring upwards and engage with the slot 4, thus completing the rapid assembly of the first square tube 1 and the second square tube 2, thereby improving work efficiency. The invention also incorporates a first functional layer 12, including a ceramic layer 1201 and a polytetrafluoroethylene (PTFE) layer 1202. The ceramic layer 1201 effectively prevents corrosive liquids or gases from eroding the first square tube 1, exhibiting excellent performance, especially in acidic or alkaline environments, thereby extending the overall service life. The PTFE layer... The epoxy layer 1202 has excellent chemical corrosion resistance, resisting corrosion from most acids, alkalis, and solvents. It can form a dense protective film on the surface of the first square tube 1, preventing chemical media from damaging it. It is suitable for more demanding chemical environments. By setting a second functional layer 13 including a polyurethane coating 1301 and an epoxy resin coating 1302, the polyurethane coating 1301 has excellent wear resistance and impact resistance, making it suitable for outer protection. It can effectively resist external physical damage and prevent wear during transportation, installation, or external impacts, increasing mechanical strength and surface protection. The epoxy resin coating 1302 can prevent chemical corrosion in the external environment from damaging the first square tube 1. Its high adhesion and excellent durability ensure that the first square tube 1 can be effectively protected in various environments.
