Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a multi-pipe lamp post structure that requires no welding connection. Background Technology

[0002] Lighting fixtures typically use the shape design of multiple pipe-shaped light poles. The connection of multiple pipe-shaped light poles has always been mainly by welding. Welding has many drawbacks, including: (1) high cost of welding light pole structure, difficulty in polishing weld scars after welding, and high welding defect rate; (2) after welding, the light pole structure cannot be disassembled or is difficult to disassemble; (3) plastic light poles are difficult to weld.

[0003] With technological advancements, weld-free light poles are gradually emerging. See Chinese patent document ZL202322652797.0, which discloses a weld-free light pole assembly, including a first hollow light pole, a second hollow light pole, a third hollow light pole, and a metal connecting piece. Each of the first, second, and third hollow light poles has a insertion hole on one side. The metal connecting piece includes a first pin, a second pin, and a third pin, with one end of each pin interconnected. The first pin has a first elastic buckle, the second pin has a second elastic buckle, and the third pin has a third elastic buckle. This light pole assembly connects the light poles via the metal connecting piece, eliminating the need for welding between the three hollow light poles. However, the lamp post assembly also has the following technical problems: each metal connecting piece can only be fixed to the hollow lamp post from one point, resulting in poor connection stability. Furthermore, the connection is fixed solely by the elastic buckle of the metal connecting piece hooking onto the socket of the hollow lamp post. When the hollow lamp post is pulled outward, the elastic buckle is prone to spring deformation and loosening from the socket, thus making the connection between the metal connecting piece and the hollow lamp post unstable. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a multi-tube lamp post structure that eliminates the need for welding, based on the shortcomings of the prior art. This lamp post structure enables multiple lamp tubes to be connected together without welding, and the connection is stable and not easy to loosen.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a multi-tube lamp post structure with weld-free connection, including at least three lamp tubes, a pin, and a metal spring. Each lamp tube has an elongated opening at its upper end. The side of the pin has several elongated grooves corresponding to the elongated openings, and the two side walls of the elongated openings are respectively inserted into the corresponding elongated grooves. The length of the pin is less than the length of the elongated opening. The metal spring includes a bottom connecting piece, and at least two "V"-shaped elastic buckles corresponding to the elongated openings are integrally connected to the side of the bottom connecting piece. The bottom connecting piece abuts against the upper end of the pin, and the "V"-shaped elastic buckles are inserted into the corresponding elongated openings and are interference-fitted with the two side walls of the elongated openings.

[0006] In the above technical solution, the lamp tube is a lamp tube with a circular, square or elliptical cross-section, and the width of the elongated opening is smaller than the width of the lamp tube.

[0007] In the above technical solution, at least three lamp tubes are close together and evenly arranged around the center line of the pin, with the elongated opening of each lamp tube facing the center line of the pin. The number of "V"-shaped elastic buckles of the metal spring matches the number of elongated openings, with at least three "V"-shaped elastic buckles evenly arranged around the bottom connecting piece, each "V"-shaped elastic buckle inserted into a corresponding elongated opening. The number of elongated slots of the pin matches the number of elongated openings, with at least three elongated slots evenly arranged around the center line of the pin, and the sidewalls of the elongated openings of two adjacent lamp tubes inserted into a corresponding elongated slot. Preferably, the number of lamp tubes is five, the metal spring has five "V"-shaped elastic buckles, and the pin has five elongated slots.

[0008] In the above technical solution, the inner width of the elongated groove is greater than the outer width of the elongated groove.

[0009] In the above technical solution, the lamp tube is a metal lamp tube or a plastic lamp tube, the pin is a nylon pin or an aluminum alloy pin, and the metal spring is a spring steel metal spring.

[0010] The beneficial effects of this utility model are: (1) Since each lamp tube has a long strip-shaped opening at its upper end, and the side of the pin has several long strip-shaped grooves corresponding to the long strip-shaped opening, and the two side walls of the long strip-shaped opening are respectively inserted into the corresponding long strip-shaped grooves, the lamp tubes can be connected together without welding using the pin, and the connection is effective and stable, the connection cost is low, the grinding process of the connection position can be eliminated, each lamp tube can be easily disassembled, and lamp tubes made of metal and plastic can be connected; (2) Since the length of the pin is less than the length of the long strip-shaped opening, the metal spring includes a bottom connecting piece, and at least two long strip-shaped grooves are integrally connected to the side of the bottom connecting piece. The corresponding "V" shaped elastic buckle is inserted into the corresponding long strip opening and is pressurized with the upper end of the pin. Therefore, this utility model can use the elastic effect of the "V" shaped elastic buckle of the metal spring to clamp and fix it with the long strip opening, preventing the pin from sliding out. (3) This utility model adopts a structure in which the long strip opening and the long strip groove are inserted and fixed. Compared with the structure in the prior art where the metal connecting piece and the hollow lamp post are inserted and fixed, the connection position of this utility model is not just a point, but a line, and there is no problem of the pin loosening due to elastic deformation. The connection stability is significantly improved. Attached Figure Description

[0020] The structural and working principles of this utility model will be further described in detail below with reference to the accompanying drawings.

[0021] like Figures 1-8 As shown, this utility model is a multi-tube lamp post structure with a weld-free connection, including at least three lamp tubes 1, a pin 2, and a metal spring 3. Each lamp tube 1 has an elongated opening 11 at its upper end. The side of the pin 2 has several elongated grooves 21 corresponding to the elongated openings 11. The two side walls of the elongated openings 11 are respectively inserted into the corresponding elongated grooves 21. The length of the pin 2 is less than the length of the elongated openings 11. The metal spring 3 includes a bottom connecting piece 31. At least two "V"-shaped elastic buckles 32 corresponding to the elongated openings 11 are integrally connected to the side of the bottom connecting piece 31. The bottom connecting piece 31 abuts against the upper end of the pin 2. The "V"-shaped elastic buckles 32 are inserted into the corresponding elongated openings 11 and are interference-fitted with the two side walls of the elongated openings 11. This invention enables the solderless connection of each lamp tube 1 using the pin 2, resulting in an effective and stable connection at a low cost. It eliminates the need for grinding at the connection points, allows for easy disassembly of each lamp tube, and can connect lamp tubes made of metal or plastic. Furthermore, the invention utilizes the elasticity of the "V"-shaped elastic buckle 32 of the metal spring 3 to engage with the elongated opening 11, preventing the pin 2 from slipping out. Compared to the existing structure where metal connecting pieces are inserted into hollow lamp posts, this invention provides a connection along a line rather than a single point, eliminating the problem of the pin 2 loosening due to elastic deformation, thus significantly improving connection stability.

[0022] In a preferred embodiment of this utility model, the lamp tube 1 is a lamp tube 1 with a circular, square or elliptical cross-section, and the width of the elongated opening 11 is smaller than the width of the lamp tube 1.

[0023] like Figures 1-6 As shown, at least three lamp tubes 1 are close together and evenly arranged around the center line of the pin, with the elongated opening 11 of each lamp tube 1 facing the center line of the pin. The number of "V"-shaped elastic buckles 32 of the metal spring 3 matches the number of elongated openings 11, with at least three "V"-shaped elastic buckles 32 evenly arranged around the bottom connecting piece 31, and each "V"-shaped elastic buckle 32 inserted into a corresponding elongated opening 11. The number of elongated slots 21 of the pin 2 matches the number of elongated openings 11, with at least three elongated slots 21 evenly arranged around the center line of the pin 2, and the sidewalls of the elongated openings 11 of two adjacent lamp tubes 1 inserted into a corresponding elongated slot 21.

[0024] As a preferred embodiment of this utility model, such as Figures 1-6 As shown, there are five lamp tubes 1, the metal spring 3 has five "V" shaped elastic buckles 32, and the pin 2 has five elongated slots 21.

[0025] As a preferred embodiment of this utility model, such as Figures 1-6 As shown, the inner width of the elongated groove 21 is greater than the outer width of the elongated groove 21.

[0026] In a preferred embodiment of this utility model, the lamp tube 1 is a metal lamp tube 1 or a plastic lamp tube 1, the pin 2 is a nylon pin 2 or an aluminum alloy pin 2, and the metal spring 3 is a spring steel metal spring 3.

[0027] This utility model takes a multi-tube lamp post structure with five lamp tubes 1 as an example, and its installation and connection method is as follows:

[0028] Step 1, as follows Figure 7 As shown, five light tubes 1 are placed close together and evenly arranged, with the elongated opening 11 of each light tube 1 facing the center.

[0029] Step 2, as follows Figure 8 As shown, push the pin 2 into the center of the five lamp tubes 1, and insert the side walls of the elongated openings 11 of the five lamp tubes 1 into the corresponding elongated slots 21 of the pin 2. At this time, the five lamp tubes 1 are connected to each other by the pin 2 and are not loose.

[0030] Step 3, as follows Figure 9 As shown, push the metal spring 3 into the center of the five lamp tubes 1 until it contacts the pin 2. The "V"-shaped elastic buckle 32 of the metal spring 3, due to its elasticity, locks against the side wall of the elongated opening 11 of the lamp tube 1, forming a fixed structure and preventing the pin 2 from sliding out from the top of the lamp tube 1. At this point, the installation of the five lamp tubes 1 is complete. Figure 1 As shown, all five lamp tubes 1 are firmly fastened together by the pins 2 and the metal springs 3.

[0031] The above description is merely a preferred embodiment of this utility model. Any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical solution of this utility model shall fall within the scope of the technical solution of this utility model.
