[0002] Connectors are used to connect the various parts of the display rack to form a stable structure. Common types of connectors include pipe connectors, plate connectors and special connectors. Pipe connectors are used to connect round or square pipes to form a rack structure. Common three-way and four-way pipe connectors, the three-way can connect three pipes, allowing the rack to extend in different directions; the four-way can connect four pipes to form a more complex structure. There are also pipe clamps, which are used to connect the ends of two pipes to extend the pipes or connect different parts. When assembling the display rack, tools are needed to lock it, which is time-consuming and laborious, and it is not easy to adjust the size of the display rack. At the same time, after long-term use, the connector is prone to rust, and the rusted connector is not easy to be pulled out. Summary of the invention

[0010] In one embodiment, a pushing inclined surface is provided at one end of the locking rod adjacent to the extension tube, a restoring inclined surface is provided at one end of the locking rod away from the extension tube, a spring groove is provided on the side wall of the end of the sliding groove away from the extension tube, a telescopic spring is installed inside the sliding groove, one end of the telescopic spring is received in the spring groove, and the other end of the telescopic spring abuts against the side wall of one end of the extension tube adjacent to the spring groove, a sleeve is provided on the outside of the telescopic spring, the sleeve is received in the sliding groove, and one end of the sleeve is fixedly installed on the side wall of the sliding groove.

[0011] In one embodiment, the rust-proof component includes a storage component and four oil outlet pipes, one side wall of the storage component is fixedly connected to the side wall of the sliding groove, and one end of the four oil outlet pipes is connected to the other side of the storage component.

[0012] In one embodiment, the storage component includes an oil storage ring and an oil supply pipe. One side wall of the oil storage ring is fixedly connected to the side wall of the sliding groove. The oil supply pipe is received in the fixed pipe, and one end of the oil supply pipe is inserted in the oil storage ring. Four through grooves are formed at the end of the sleeve away from the oil storage ring. The four through grooves all penetrate the end surface of the sleeve. Four arc grooves are formed at the end of the extension pipe adjacent to the oil storage ring. The four arc grooves all penetrate the end side wall surface of the extension pipe. Lubricating oil is stored in the oil storage ring and the four oil outlet pipes.

[0013] In one embodiment, one end of each of the four oil outlet pipes is connected to the other side of the storage element, and an oil outlet is formed at one end of each oil outlet pipe adjacent to the extension pipe.

[0014] The present invention also provides a display rack, comprising a plurality of connecting rods and the connector as described above, wherein the plurality of connecting rods are respectively inserted into the straight-through pipe mechanism of the connector, and the end side wall of each connecting rod is provided with a first fixing groove and a second fixing groove, and the first fixing groove and the second fixing groove both penetrate the two side wall surfaces of the connecting rod, and the first fixing groove is located on the side adjacent to the oil storage ring, and an alignment mark is installed on the side wall of each connecting rod.

[0015] The present invention sets a connecting rod. After the connecting rod is inserted into the insertion slot of the extension tube, the end of the connecting rod will contact the push-up inclined surface of the positioning rod, so that the positioning rod moves toward the side away from the connecting rod, and the positioning plate moves with the positioning rod, so that the two compression springs are stretched, and the connecting rod continues to move. Finally, the positioning rod away from the oil storage ring is sequentially clamped into the second clamping slot, the second passage slot and the first fixed slot under the restoring force of the two compression springs, and the connecting rod is fixed to prevent the connecting rod from falling out. No tool locking is required, and it can be completed with one hand. At the same time, a restoring inclined surface is provided at one end of the positioning rod away from the extension tube, and the inclined surface length of the restoring inclined surface is small, so that the connecting rod will not be pulled out.

[0016] The connector and the display stand are both made of metal material, which has high hardness and can well support the items. The connection structure of the present invention can also be applied to other multi-channel pipes.

[0017] By setting the lubricating oil, the connecting rod continues to be inserted into the sliding groove, the connecting rod will push the extension tube to move toward one side of the oil storage ring, and the two retaining plates will follow the extension tube to move to prevent the extension tube from detaching from the fixed tube. When the extension tube moves toward one side of the oil storage ring, one end of the extension tube adjacent to the oil storage ring will push and squeeze the four oil outlet pipes. After the four oil outlet pipes are squeezed, the lubricating oil stored inside is released through the oil outlet port. The lubricating oil flows out through the oil outlet port and enters the sliding groove. After the oil outlet pipe located above the extension tube is squeezed, the lubricating oil will drip on the side wall of the extension tube to prevent the extension tube from being corroded by the atmosphere after long-term use. At the same time, the lubricating oil flows along the outer wall of the extension tube and falls into the sliding groove, which can reduce the friction between the retaining plate and the sliding groove, thereby reducing the insertion force of the connecting rod.

[0018] By setting an oil storage ring, when the connecting rod continues to move toward one side of the oil storage ring, the sleeve will pass through the arc groove of the extension tube, the telescopic spring will be compressed, and the end of the connecting rod will contact the pushing inclined surface of the locking rod located adjacent to the oil storage ring, so that the locking rod moves toward the side away from the connecting rod, and the retaining plate moves with the locking rod, so that the two compression springs are stretched, and the connecting rod continues to move. Finally, the locking rod adjacent to the oil storage ring is sequentially locked into the first locking groove, the first pass groove and the first fixed groove under the action of the restoring force of the two compression springs, and the locking rod away from the oil storage ring is sequentially locked into the second locking groove, the second pass groove and the second fixed groove under the action of the restoring force of the two compression springs. The two locking rods fix the connecting rod to prevent the connecting rod from falling out. No tools are required for locking. It is simple and convenient, and the size of the display stand can be changed.

[0019] By setting a telescopic spring, when it is necessary to expand the display stand or disassemble the display stand, the connecting rod is continued to move toward one side of the oil storage ring, and the end of the connecting rod will squeeze the oil storage ring, so that the lubricating oil in the oil storage ring flows out through the oil outlets of the four oil outlet pipes and enters the sliding groove. After the oil outlet pipe located above the extension tube is squeezed by the extension tube, the lubricating oil will drip on the side wall of the extension tube to prevent the extension tube from being corroded by the atmosphere after long-term use, thereby generating rust residue, thereby affecting the use of the connector. At the same time, the lubricating oil flows along the outer wall of the extension tube. When the lubricating oil flows to the infiltration groove, part of the lubricating oil will flow into the insertion groove to lubricate the friction between the connecting rod and the extension tube and between the connecting rod and the extension tube. After the connecting rod continues to move toward one side of the oil storage ring, the connecting rod is rotated, and the positioning rod is lifted up and held against the side wall of the connecting rod. The positioning rod is rotated so that the positioning rod is misaligned with the first fixed groove. The connecting rod can be quickly pulled out or pulled out in cooperation with the telescopic spring, thereby reducing the force for pulling out or pulling out the connecting rod, thereby quickly disassembling the display stand without the need for tools.

[0020] The present invention has a simple structure, can easily assemble the display stand, does not require tools for assembly and disassembly, can also change the size of the display stand, and can also prevent the connector from rusting inside after long-term use, so that the connecting rod cannot be inserted and cannot be used.

[0041] like Figures 4 to 7 As shown, one end of the four oil outlet pipes 42 is connected to the other side of the storage member 41 , and an oil outlet 420 is formed at one end of each oil outlet pipe 42 adjacent to the extension pipe 23 .

[0042] like Figures 1 to 7 As shown, the present invention also provides a display stand, which includes a plurality of connecting rods 50 and the connector 60 as described above, the plurality of connecting rods 50 are respectively inserted into the straight pipe mechanism 11 of the connector 60, and the end side wall of each connecting rod 50 is provided with a first fixing groove 510 and a second fixing groove 511, the first fixing groove 510 and the second fixing groove 511 both penetrate the two side wall surfaces of the connecting rod 50, and the first fixing groove 510 is located on the side adjacent to the oil storage ring 43, and the side wall of each connecting rod 50 is installed with an alignment mark 512.

[0043] During installation: the bottoms of the three straight-through pipe mechanisms 11 are all installed on the top of the pad 10, the fixed pipe assembly 20 is installed on the top of the pad 10, the anti-rust assembly 40 is fixedly installed inside the fixed pipe assembly 20, the fixed pipe 21 is installed on the top of the pad 10, and one end of the sleeve 241 is fixedly installed on the side wall of the sliding groove 24.

[0044] When in use: 1. Insert the connecting rod 50 into the insertion groove 230 of the extension tube 23 according to the alignment of the first fixing groove 510 and the alignment mark 512. By controlling the position of the connecting rod 50 inserted into the sliding groove 24, the size of the display rack can be increased or decreased. After the connecting rod 50 is inserted into the insertion groove 230 of the extension tube 23, the end of the connecting rod 50 will contact the pushing inclined surface 320 of the positioning rod 32, so that the positioning rod 32 moves toward the side away from the connecting rod 50, and the positioning plate 34 moves with the positioning rod 32, so that the two compression springs 33 are stretched, and the connecting rod 50 continues to move. Finally, the positioning rod 32 away from the oil storage ring 43 is successively clamped into the second clamping groove 211, the second passage groove 232 and the first fixing groove 510 under the action of the restoring force of the two compression springs 33, thereby fixing the connecting rod 50 to prevent the connecting rod 50 from falling out. No tool is required for locking, and it can be completed with one hand. At the same time, a restoring inclined surface 321 is formed at one end of the locking rod 32 away from the extension tube 23 . The length of the restoring inclined surface 321 is small, so that the connecting rod 50 will not be pulled out.

[0045] 2. When the display rack needs to be reduced in size or reinforced, the connecting rod 50 can be further inserted into the sliding groove 24, and the connecting rod 50 will push the extension tube 23 to move toward one side of the oil storage ring 43. The two positioning plates 22 move with the extension tube 23 to prevent the extension tube 23 from being separated from the fixed tube 21. When the extension tube 23 moves toward one side of the oil storage ring 43, one end of the extension tube 23 adjacent to the oil storage ring 43 will push and squeeze the four oil outlet pipes 42. After being squeezed, the four oil outlet pipes 42 pass through the oil outlet 420. The lubricating oil stored inside is released, and the lubricating oil flows out through the oil outlet 420 and enters the sliding groove 24. After the extension tube 23 is squeezed, the oil outlet pipe 42 located above the extension tube 23 will drip the lubricating oil on the side wall of the extension tube 23 to prevent the extension tube 23 from being corroded by the atmosphere after long-term use. At the same time, the lubricating oil flows along the outer wall of the extension tube 23 and falls into the sliding groove 24, which can reduce the friction between the positioning plate 22 and the sliding groove 24, thereby reducing the insertion force of the connecting rod 50.

[0046] 3. The connecting rod 50 continues to move toward one side of the oil storage ring 43, the sleeve 241 will pass through the arc groove 431 of the extension tube 23, the telescopic spring 240 will be compressed, and the end of the connecting rod 50 will contact the push inclined surface 320 of the positioning rod 32 located adjacent to the oil storage ring 43, so that the positioning rod 32 moves toward the side away from the connecting rod 50, and the positioning plate 34 moves with the positioning rod 32, so that the two compression springs 33 are stretched, and the connecting rod 50 continues to move, and finally the positioning rod 32 adjacent to the oil storage ring 43 Under the action of the restoring force of the two compression springs 33, 32 is sequentially clamped into the first clamping groove 210, the first passing groove 231 and the first fixed groove 510. Under the action of the restoring force of the two compression springs 33, the clamping rod 32 away from the oil storage ring 43 is sequentially clamped into the second clamping groove 211, the second passing groove 232 and the second fixed groove 511. The two clamping rods 32 fix the connecting rod 50 to prevent the connecting rod 50 from falling out. No tool locking is required. It is simple and convenient, and the size of the display stand can be changed.

[0047] 4. When the display stand needs to be expanded or disassembled, the connecting rod 50 is further moved toward one side of the oil storage ring 43. The end of the connecting rod 50 will squeeze the oil storage ring 43, so that the lubricating oil in the oil storage ring 43 flows out through the oil outlets 420 of the four oil outlet pipes 42 and enters the sliding groove 24. After the oil outlet pipe 42 located above the extension pipe 23 is squeezed by the extension pipe 23, the lubricating oil will drip on the side wall of the extension pipe 23 to prevent the extension pipe 23 from being corroded by the atmosphere after long-term use, thereby generating rust residue, thereby affecting the use of the connector 60. At the same time, the lubricating oil flows along the outer wall of the extension pipe 23, and the lubricating oil flows When it penetrates into the infiltration groove 233, part of the lubricating oil will flow into the insertion groove 230 to lubricate the friction between the connecting rod 50 and the extension tube 23 and between the connecting rod 50 and the extension tube 23. After the connecting rod 50 continues to move toward one side of the oil storage ring 43, the connecting rod 50 is rotated, and the positioning rod 32 is lifted up and supported on the side wall of the connecting rod 50. The positioning rod 32 is rotated so that the positioning rod 32 is misaligned with the first fixed groove 510. The connecting rod 50 can be quickly pulled out or pulled out in conjunction with the telescopic spring 240, reducing the force for pulling out or pulling out the connecting rod 50, thereby quickly disassembling the display stand without the need for tools.

[0048] 5. When the connecting rod 50 is pulled out or extracted, the restoring inclined surface 321 of the locking rod 32 can squeeze the restoring inclined surface 321 of the extension tube 23 under the restoring force of the telescopic spring 240, thereby causing the locking rod 32 to move away from the side of the connecting rod 50, and the stop plate 34 moves with the locking rod 32, causing the two compression springs 33 to stretch, and the locking rod 32 pushes against the side wall of the extension tube 23, thereby causing the extension tube 23 to restore toward the side away from the oil storage ring 43 under the restoring force of the telescopic spring 240.

[0049] The present invention sets a connecting rod 50. After the connecting rod 50 is inserted into the insertion groove 230 of the extension tube 23, the end of the connecting rod 50 will contact the push-up inclined surface 320 of the positioning rod 32, so that the positioning rod 32 moves toward the side away from the connecting rod 50, and the abutment plate 34 moves with the positioning rod 32, so that the two compression springs 33 are stretched, and the connecting rod 50 continues to move. Finally, the positioning rod 32 away from the oil storage ring 43 is sequentially clamped into the second clamping groove 211, the second passage groove 232 and the first fixing groove 510 under the restoring force of the two compression springs 33, and the connecting rod 50 is fixed to prevent the connecting rod 50 from falling out. No tool locking is required, and it can be completed by one hand. At the same time, a restoring inclined surface 321 is provided at one end of the positioning rod 32 away from the extension tube 23, and the inclined surface length of the restoring inclined surface 321 is small, so that the connecting rod 50 will not be pulled out.

[0050] By setting the lubricating oil, the connecting rod 50 is further inserted into the sliding groove 24, and the connecting rod 50 will push the extension tube 23 to move toward one side of the oil storage ring 43. The two positioning plates 22 follow the extension tube 23 to move to prevent the extension tube 23 from detaching from the fixed tube 21. When the extension tube 23 moves toward one side of the oil storage ring 43, one end of the extension tube 23 adjacent to the oil storage ring 43 will push and squeeze the four oil outlet pipes 42. After the four oil outlet pipes 42 are squeezed, the lubricating oil stored inside is released through the oil outlet 420. The lubricating oil flows out through the oil outlet 420 and enters the sliding groove 24. After the oil outlet pipe 42 located above the extension tube 23 is squeezed by the extension tube 23, the lubricating oil will drip on the side wall of the extension tube 23 to prevent the extension tube 23 from being corroded by the atmosphere after long-term use. At the same time, the lubricating oil flows along the outer wall of the extension tube 23 and falls into the sliding groove 24, which can reduce the friction between the positioning plate 22 and the sliding groove 24, thereby reducing the insertion force of the connecting rod 50.

[0051] By providing the oil storage ring 43, when the connecting rod 50 continues to move toward one side of the oil storage ring 43, the sleeve 241 will pass through the arc groove 431 of the extension tube 23, the telescopic spring 240 will be compressed, and the end of the connecting rod 50 will contact the push inclined surface 320 of the positioning rod 32 located adjacent to the oil storage ring 43, so that the positioning rod 32 moves toward the side away from the connecting rod 50, and the positioning plate 34 moves with the positioning rod 32, so that the two compression springs 33 are stretched, and the connecting rod 50 continues to move, and finally adjacent to the oil storage ring 43. Under the action of the restoring force of the two compression springs 33, the locking rod 32 is sequentially locked into the first locking groove 210, the first passing groove 231 and the first fixed groove 510; the locking rod 32 away from the oil storage ring 43 is sequentially locked into the second locking groove 211, the second passing groove 232 and the second fixed groove 511 under the action of the restoring force of the two compression springs 33. The two locking rods 32 fix the connecting rod 50 to prevent the connecting rod 50 from falling out. No tool locking is required, which is simple and convenient, and the size of the display stand can be changed.

[0052] By setting the telescopic spring 240, when the display rack needs to be expanded or disassembled, the connecting rod 50 is further moved toward one side of the oil storage ring 43, and the end of the connecting rod 50 will squeeze the oil storage ring 43, so that the lubricating oil in the oil storage ring 43 flows out through the oil outlets 420 of the four oil outlet pipes 42 and enters the sliding groove 24. After the oil outlet pipe 42 located above the extension pipe 23 is squeezed by the extension pipe 23, the lubricating oil will drip on the side wall of the extension pipe 23, so as to prevent the extension pipe 23 from being corroded by the atmosphere after long-term use, thereby generating rust residue, and further affecting the use of the connector 60. At the same time, the lubricating oil flows along the outer wall of the extension pipe 23 When the lubricating oil flows into the infiltration groove 233, part of the lubricating oil will flow into the insertion groove 230 to lubricate the friction between the connecting rod 50 and the extension tube 23 and between the connecting rod 50 and the extension tube 23. After the connecting rod 50 continues to move toward one side of the oil storage ring 43, the connecting rod 50 is rotated, and the positioning rod 32 is lifted up and supported on the side wall of the connecting rod 50. The positioning rod 32 is rotated so that the positioning rod 32 is misaligned with the first fixing groove 510. The connecting rod 50 can be quickly pulled out or pulled out in conjunction with the telescopic spring 240, reducing the force for pulling out or pulling out the connecting rod 50, thereby quickly disassembling the display stand without the need for tools.

[0053] The present invention has a simple structure and can easily assemble the display stand without tools for assembly and disassembly. The size of the display stand can also be changed. At the same time, it can prevent the connector 60 from rusting after long-term use, so that the connecting rod 50 cannot be inserted and cannot be used.

[0054] All possible combinations of the various technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-mentioned embodiments only express several embodiments of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
