Description

Technical Field

[0001] The invention relates to the field of educational lighting lamp products, and in particular to a structure with an adjustable length of a mounting suspension rod. Background Art

[0002] Most lighting products need to be fixed to the ceiling through a suspension rod, such as classroom lamps and blackboard lamps. During production, the length of the suspension rod is usually fixed. However, when installed in an actual classroom lighting scenario, due to factors such as the ceiling height of different classrooms, there is a certain gap between the most suitable installation height of the lamp and the designed length of the suspension rod, and it cannot be adjusted during the installation process, so the optimal lighting effect cannot be achieved. If the suspension rod is designed as an ordinary retractable structure, there is a problem that the wires cannot be passed through, and the wires can only be exposed. The wires are easily damaged when exposed to the air, which reduces the service life of the wires. It is necessary to improve the above problems and design a structure with an adjustable length of the installation suspension rod whose internal cavity can pass the wires. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a structure with a simple structure, convenient length adjustment and adjustable length of the installation hanger rod capable of accommodating electric wires in view of the problems existing in the prior art.

[0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a structure for installing a suspension rod with adjustable length, comprising a suspension rod body, the suspension rod body comprising a fixed-length tube, a spring-loaded assembly and an adjusting sleeve, the fixed-length tube being integrally formed with a first chamber and a second chamber which are close to each other, a mounting through hole being provided on the side wall of at least one end of the first chamber, a spring-loaded assembly being provided in the mounting through hole, an adjusting sleeve being sleeved on at least one end of the fixed-length tube, the adjusting sleeve being integrally formed with a first sleeve and a second sleeve which are interconnected, the inner wall of the first sleeve matching the outer wall of the first chamber, the inner wall of the second sleeve matching the outer wall of the second chamber, a plurality of telescopic positioning holes matching the spring-loaded assembly being provided on the side wall of the first sleeve, and a threading hole being provided on the end of the second sleeve away from the fixed-length tube.

[0005] Furthermore, the inner diameter of the first chamber is greater than the inner diameter of the second chamber.

[0006] Furthermore, the snap assembly includes a snap seat and a clamping spring, the end of the snap seat is provided with a limiting hole matching the clamping spring, and the inner wall of the first chamber is provided with a limiting strip groove matching the clamping spring.

[0007] Furthermore, a single adjusting sleeve is provided with five telescopic positioning holes.

[0008] Furthermore, the fixed-length tube and the adjusting sleeve are made of extruded aluminum profiles, and the surfaces of the fixed-length tube and the adjusting sleeve are both oxidized.

[0009] Compared with the prior art, the structure for installing the adjustable length of the hanger of the present invention designs the hanger body into a double-chamber structure, which is shaped like an "8", and solves the problem that ordinary retractable structures cannot pass the wire. One chamber cooperates with a spring buckle to adjust the size, and the other chamber can pass the wire through to ensure that the wire is in the cavity, which can slow down the aging of the wire. In addition, the hanger body adopts a spring buckle structure, and a plurality of telescopic positioning holes are evenly arranged to match it, so that the length can be accurately adjusted. In addition, the fixed-length tube and the adjusting sleeve are made of extruded aluminum profiles with surface oxidation treatment. The structure is strong and durable, and it has good promotion and application value. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention is further described in detail below with reference to the accompanying drawings.

[0017] like Figures 1 to 5 As shown, a structure for installing a suspension rod with adjustable length includes a suspension rod body 1, the upper end of the suspension rod body 1 is fixedly installed on the ceiling, and the lower end of the suspension rod body 1 is fixedly connected to the lamp body.

[0018] The boom body 1 includes a fixed-length tube 11, a snap-on assembly 12 and an adjusting sleeve 13. The fixed-length tube 11 is integrally formed with a first chamber 111 and a second chamber 112 which are close to each other. A mounting hole 1111 is provided on the side wall of at least one end of the first chamber 111, and the snap-on assembly 12 is arranged in the mounting hole 1111. At least one end of the fixed-length tube 11 is sleeved with an adjusting sleeve 13. The adjusting sleeve 13 is integrally formed with a first sleeve 131 and a second sleeve 132 which are connected to each other. The first sleeve 131 and the second sleeve 132 are respectively matched with the first chamber 111 and the second chamber 112. A plurality of telescopic positioning holes 1311 which match the snap-on assembly 12 are provided on the side wall of the first sleeve 131, and a threading hole 1321 is provided at the end of the second sleeve 132 away from the fixed-length tube 11.

[0019] The second chamber 112 is used to pass the wire, and the first chamber 111 is used to adjust the length in combination with the snap assembly 12 . The inner diameter of the second chamber 112 is slightly larger than the diameter of the wire, and the inner diameter of the first chamber 111 is larger than the inner diameter of the second chamber 112 .

[0020] The snap-on assembly 12 includes a snap-on seat 121 and a clamping spring 122. The clamping spring 122 is shaped like a "V". A limiting hole 1211 matching the clamping spring 122 is provided at the end of the snap-on seat 121 for inserting and fixing the clamping spring 122. A limiting strip groove 1112 is provided on the inner wall of the first chamber 111 to match the clamping spring 122, so that the clamping spring 122 can press against the inner wall of the first chamber 111, making it difficult to move and having a firm structure.

[0021] In addition, the fixed-length tube 11 and the adjusting sleeve 13 are made of extruded aluminum profiles with surface oxidation treatment, and have a strong structure and are durable.

[0022] In this embodiment, both ends of the fixed-length tube 11 are provided with adjustment sleeves 13, and a total of five telescopic positioning holes 1311 are provided, so that the adjustment range is wide.

[0023] The structure for installing the adjustable length of the suspension rod of the present invention designs the suspension rod body as a double-chamber structure, which is shaped like an "8", and solves the problem that ordinary retractable structures cannot pass the wire. One chamber cooperates with a spring buckle to adjust the size, and the other chamber can pass the wire through to ensure that the wire is in the cavity, which can slow down the aging of the wire. The suspension rod body adopts a spring buckle structure, and a plurality of telescopic positioning holes are evenly arranged to match it, so that the length of the suspension rod can be accurately adjusted, which is suitable for more installation sites and achieves better lighting effects.
