Description

Technical Field

[0001] This utility model belongs to the field of support technology, and specifically relates to a telescopic support. Background Technology

[0002] In traditional telescopic brackets, the connection between the multi-section bracket body and the telescopic drive components (such as telescopic rods and cylinders) is often achieved by welding or direct sleeve connection. After long-term use, the welded joints are prone to oxidation and desoldering, while the sleeved joints experience increased gaps due to wear. This not only affects the smoothness of telescopic movement but also accelerates component wear, shortens the overall service life of the bracket, and increases the user's maintenance costs and replacement frequency. Utility Model Content

[0003] To solve the technical problem of low reliability of existing telescopic support component connections.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a telescopic support, comprising a first support, a second support, and a third support, wherein the second support is disposed within the first support, and the third support is disposed within the second support;

[0005] The second bracket is provided with a first cylinder and a second cylinder. The first cylinder is provided with a first telescopic rod, and the second cylinder is provided with a second telescopic rod. The ends of the first telescopic rod and the second telescopic rod are provided with threads.

[0006] The first telescopic rod is screwed into the first bracket by threads, and the second telescopic rod is screwed into the third bracket by threads.

[0007] Furthermore, the first cylinder block and the second cylinder block are provided with connecting plates at their ends, and the connecting plates are fixedly connected to the first cylinder block and the second cylinder block respectively by screws.

[0008] The present invention has the following advantages: when the third bracket is pressed down, the second telescopic rod in the third bracket retracts into the second cylinder, thereby retracting the third bracket into the second bracket, and the first telescopic rod retracts into the first cylinder, thereby retracting the second bracket into the first bracket, thus completing the storage of the telescopic bracket. The structure is simple and the operation is convenient. Attached Figure Description

[0013] like Figures 1 to 3 As shown, a telescopic support includes a first support 10, a second support 20 and a third support 30, wherein the second support 20 is disposed in the first support 10 and the third support 30 is disposed in the second support 20.

[0014] The second bracket 20 is provided with a first cylinder 210 and a second cylinder 220. The first cylinder 210 is provided with a first telescopic rod 211, and the second cylinder 221 is provided with a second telescopic rod 221. The ends of the first telescopic rod 211 and the second telescopic rod 221 are both provided with threads 201.

[0015] The first telescopic rod 211 is screwed to the first bracket 10 via thread 201, and the second telescopic rod 221 is screwed to the third bracket 30 via thread 201.

[0016] When in use, press the third bracket 30 firmly, and the second telescopic rod 221 in the third bracket 30 will retract into the second cylinder 220, so that the third bracket 30 will retract into the second bracket 20. The first telescopic rod 211 will retract into the first cylinder 210, so that the second bracket 20 will retract into the first bracket 10, thus completing the storage of the telescopic bracket. The structure is simple and the operation is convenient.

[0017] The first cylinder 210 and the second cylinder 220 are provided with connecting plates 230 at their ends. The connecting plates 230 are fixedly connected to the first cylinder 210 and the second cylinder 220 respectively by screws. During use, the first cylinder 210 and the second cylinder 220 are fixedly connected to prevent displacement during extension and retraction.
