Description

Technical Field

[0001] This utility model relates to the field of umbrella rod technology, specifically to a telescopic structure for an umbrella rod with a built-in shock-absorbing spring. Background Technology

[0002] The umbrella handle, acting as the core of the umbrella, opens and closes the canopy through a telescopic structure. Its core structure includes a spring energy storage device, a button trigger mechanism, and a lever transmission system. The telescopic structure allows the umbrella to be folded and stored for easy carrying. The handle's telescopic rod structure allows for adjustment of the handle length by stretching or retracting the rod, thus meeting the user's needs in different scenarios.

[0003] Chinese patent CN201504666U proposes a telescopic umbrella rod structure, including an inner tube and an outer tube, which are sleeved together. A bushing is embedded in the inner hole at the upper end of the outer tube, and the inner hole of the bushing is in sliding fit with the outer surface of the inner tube. A positioning key is fixed in the inner hole of the bushing, and the positioning key is opposite to a groove or plane extending axially along the outer surface of the inner tube. The groove or plane has a protrusion at the lower end of the inner tube. When the inner tube extends to its limit position, the protrusion abuts against the lower end of the positioning key. The process is simple and low-cost. The bushing can be made of a friction-reducing material, which reduces the sliding friction resistance of the inner tube movement, making the opening and closing of the umbrella smooth. If plastic is used as the bushing, the production cost can be further reduced, the sliding friction resistance of the inner tube movement can be reduced, the inner tube can be prevented from being damaged, and the service life of multi-fold umbrellas can be improved.

[0004] The above solution reduces production costs, decreases the sliding friction resistance of the inner tube movement, and prevents the inner tube from being damaged. During the use of the umbrella, rainwater easily adheres to the surface of the umbrella rod telescopic structure. Rainwater can easily seep into the interior of the umbrella rod telescopic structure through the gaps. If not dealt with in time, the umbrella rod telescopic structure is very prone to rust, which will affect the smoothness of the umbrella's use. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a telescopic structure for an umbrella rod with a built-in shock-absorbing spring, which can promptly remove residual moisture from the surface of the telescopic structure and prevent residual rainwater from causing the telescopic rod to rust.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a telescopic umbrella rod structure with built-in shock-absorbing spring, including a handle, a telescopic rod fixedly installed on the top of the handle, an anti-rust component provided inside the telescopic rod, an adjusting ring slidably connected to the outer end of the telescopic rod, multiple sets of supporting umbrella frames fixedly installed on the outer end of the adjusting ring, a shock-absorbing limiting component provided at the outer end of the telescopic rod, and a fixing component provided inside the telescopic rod;

[0007] The rust-prevention component includes a placement slot, which is located inside the telescopic rod. Multiple reinforcing rods are fixedly installed inside the placement slot. Multiple diffusion holes are fixedly installed on both the inner and outer walls of the telescopic rod. A desiccant is placed inside the placement slot.

[0008] Preferably, the shock absorption limiting assembly includes a fixing plate, which is fixedly installed on the outer end of the telescopic rod. Multiple shock absorption spring bodies are fixedly installed on the bottom of the fixing plate, and multiple limiting plates are installed on the bottom of each shock absorption spring body. A buffer pad is fixedly installed on the bottom of the limiting plate.

[0009] Preferably, the fixing component includes guide rods, two of which are fixedly installed inside the telescopic rod, and a fixing ring is fixedly installed between the two guide rods.

[0010] Preferably, the outer ends of the two guide rods are symmetrically fitted with reset springs, and a connecting plate is slidably connected between the two guide rods, and a support limiting block is fixedly installed on one side of each of the two connecting plates.

[0011] Preferably, the placement slot is located in the middle part of the telescopic rod.

[0012] Preferably, the buffer pad contacts the top of the adjusting ring, and the limiting plate is located above the telescopic rod.

[0013] Preferably, the reset spring is located between the fixed ring and the connecting plate, and the support limiting block extends to the outer end of the telescopic rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This solution incorporates an anti-rust component. A desiccant is placed in the middle of the telescopic pole, and the desiccant diffuses its drying effect to the surface of the telescopic pole through diffusion holes. This dries the moisture on the surface of the telescopic pole, preventing residual rainwater from causing rust when the umbrella is stored and not in use. This helps protect the telescopic structure of the umbrella's inner pole, making its operation smoother and thus extending the umbrella's lifespan.

[0016] 2. This solution uses shock-absorbing and limiting components to buffer the impact force generated when the user opens the umbrella by utilizing the resistance of the shock-absorbing spring, thus preventing damage to the umbrella's telescopic structure due to excessive force and better protecting the telescopic structure of the umbrella's central pole.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a technical solution: a telescopic umbrella rod structure with built-in shock-absorbing spring, including a handle 1, a telescopic rod 2 fixedly installed on the top of the handle 1, an anti-rust component inside the telescopic rod 2, an adjusting ring 4 slidably connected to the outer end of the telescopic rod 2, and multiple sets of umbrella support frames 5 fixedly installed on the outer end of the adjusting ring 4. The anti-rust component includes a placement groove 31, which is opened inside the telescopic rod 2. Multiple reinforcing rods 32 are fixedly installed inside the placement groove 31. Multiple diffusion holes 33 are fixedly installed on both the inner and outer walls of the telescopic rod 2. A desiccant 34 is placed inside the placement groove 31. The desiccant 34 can absorb and dry residual water. The placement groove 31 is opened in the middle part of the telescopic rod 2. This structure can absorb and dry the residual moisture in the telescopic umbrella rod structure, preventing rust caused by residual moisture on the surface of the telescopic umbrella rod structure when the umbrella is stored, and also extending the service life of the telescopic umbrella rod structure.

[0025] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5The telescopic rod 2 has a shock-absorbing and limiting component at its outer end and a fixing component inside. The fixing component includes guide rods 71, two guide rods 71 ​​fixedly installed inside the telescopic rod 2, and a fixing ring 72 fixedly installed between the two guide rods 71. Return springs 73 are symmetrically fitted onto the outer ends of the two guide rods 71, and a connecting plate 74 is slidably connected between the two guide rods 71. A support limiting block 75 is fixedly installed on one side of each of the two connecting plates 74. The return spring 73 is located between the fixing ring 72 and the connecting plate 74, and the support limiting block 75 extends to the outer end of the telescopic rod 2. The shock-limiting assembly includes a fixing plate 61, which is fixedly installed on the outer end of the telescopic rod 2. Multiple shock-absorbing spring bodies 62 are fixedly installed on the bottom of the fixing plate 61. Multiple limit plates 63 are installed on the bottom of each shock-absorbing spring body 62. A buffer pad 64 is fixedly installed on the bottom of the limit plate 63. The buffer pad 64 is made of silicone and contacts the top of the adjusting ring 4. The limit plate 63 is located above the telescopic rod 2. This structure can buffer the impact force generated when the user opens the umbrella, avoid damage to the umbrella frame due to excessive impact, and thus better protect the umbrella rod.

[0026] Working principle: When using the umbrella, the user manually pushes the adjusting ring 4, which drives the umbrella frame 5 to open. When the adjusting ring 4 is adjusted to below the support limit block 75, the user presses the support limit block 75 with the angle below it and puts it into the telescopic rod 2. Then, the user pushes the adjusting ring 4 above the support limit block 75. The support limit block 75 supports the adjusting ring 4 with the elastic rebound of the return spring 73, thereby supporting the umbrella.

[0027] During the opening process, when the adjusting ring 4 is adjusted upward and contacts the buffer pad 64, it will press the buffer pad 64, causing the limiting plate 63 to press the shock-absorbing spring body 62. The resistance of the shock-absorbing spring body 62 is used to remind the user that the umbrella has been opened.

[0028] When the umbrella is not in use, the moisture remaining on the surface of the telescopic rod 2 can be absorbed and dried by the desiccant 34 through the diffusion holes 33, thus promptly treating the moisture remaining on the surface of the telescopic rod 2. The above is the working process of the entire device, and all contents not described in detail in this specification belong to the prior art known to those skilled in the art.
