Description

Technical Field

[0001] The utility model relates to the technical field of component unlocking methods, and particularly relates to a telescopic tube with a two-way unlocking component. Background Art

[0002] With the continuous and rapid development in China, the income of consumers has been continuously increasing, especially the rapid growth of the income level of consumers in large and medium-sized cities. The living conditions of consumers have been continuously improved. There are more and more duplex houses and large-area houses. Due to the requirements for improving the home environment and the change of consumption concepts, the demand of consumers for household products is also getting stronger. For example, handheld vacuum cleaners are the most commonly used. However, for existing household products such as handheld vacuum cleaners, the length of their conductive tubes is fixed, which not only cannot meet the usage needs of people of different heights, but also occupies a large space and is not convenient for storage and transportation.

[0003] After retrieving the utility model patent with the patent publication number of CN205197709U, it discloses a locking structure for a telescopic shower curtain rod, which relates to a locking structure of a telescopic rod member and can be used for two-way adjustment of a telescopic shower curtain rod composed of a large tube and a small tube that are telescopically and movably sleeved. The disclosed technical features are mainly that a more novel locking device is provided between the large tube and the small tube. It includes a tapered screw rod and a lock sleeve connected by tapered threads. The tapered screw rod and the lock sleeve are installed at one end of the small tube and are inserted into the large tube together and movably, and the outer surface of the lock sleeve contacts the inner wall of the large tube. The outer diameter size of the lock sleeve can be changed through the tapered thread structure, so as to realize the length expansion and contraction locking or unlocking of the telescopic shower curtain rod.

[0004] Compared with the prior art, the utility model patent with the patent publication number of CN205197709U changes the outer diameter size of the lock sleeve through the tapered thread structure, so as to realize the length expansion and contraction or unlocking of the telescopic shower curtain rod. This kind of locking device has the function of telescopic adjustment and fixed support, and can be locked without drilling holes in the wall.

[0005] However, in the above scheme, the outer diameter size of the lock sleeve is changed through the connection method of tapered threads. For this telescopic tube of this kind of telescopic method, on the one hand, the structure that needs to be rotated back and forth when retracting and extending during use is relatively complicated to adjust for the tapered threads in the above scheme, and certain tools are also required for assembly when damaged. On the other hand, the price of this kind of supporting material is relatively high, and it may be easy to cause the problem that the inside may need to be fixed after long-term use and the threads are blocked and cannot be rotated. Therefore, a telescopic tube with a two-way unlocking component is proposed. Summary of the Utility Model

[0006] The purpose of the present utility model is to solve the problems existing in the prior art that household articles with telescopic tube devices have relatively high usage costs and too many parts, which easily cause the damage of one component and lead to the inoperability of the entire device, and the situation where first-time users may need to learn. Therefore, a telescopic tube with a two-way unlocking component is proposed.

[0007] In order to achieve the above purpose, the present utility model adopts the following technical solutions:

[0008] A telescopic tube with a two-way unlocking component, including an outer tube and a push button. Inside the push button, there is a limit shaft for controlling the telescopic movement of the telescopic tube. Inside the push button, there is a positioning mechanism for fixing the length of the telescopic tube. The positioning mechanism includes a positioning pin elastic sheet inside the push button. The limit shaft is fixedly connected to the positioning pin elastic sheet. The inner tube and the outer tube are combined to form a telescopic tube;

[0009] When adjusting the length, a limit shaft driving pin for enabling the device to enter the adjustment is arranged outside the limit shaft. A slider for pushing the limit shaft driving pin is arranged outside the limit shaft. When the limit shaft driving pin is pushed by the slider, the limit shaft will be lifted and released. When the limit shaft is released, the inner tube and the outer tube inside the outer tube slide relative to each other to achieve the adjustment.

[0010] The above technical solution further includes:

[0011] The positioning pin elastic sheet has the characteristic of being able to be squeezed and rebounded. An anti-rotation groove for preventing rotation during length adjustment is arranged outside the inner tube. A first limit hole for controlling the length of retracting into the anti-rotation groove is arranged outside the inner tube. Another set of control retracting second limit holes is arranged on the side of the outer part away from the first limit hole. A joint for the inner tube to slide is arranged inside the anti-rotation groove. The surface of the joint has the effect of protecting the stable entry and exit of the inner tube.

[0012] Sliders for pushing the limit shaft driving pin are symmetrically arranged inside the push button. The sliders facilitate the telescopic movement of the two-way telescopic tube. The push button is slidably connected to the outer tube. The push button controls the telescopic tube under the sliding of the outer tube. There are heat dissipation holes outside the chassis for ensuring the temperature of the fan during operation to dissipate heat for the fan.

[0013] The present utility model has the following beneficial effects:

[0014] 1. In the present utility model, when it is necessary to adjust the length of the telescopic tube, squeezing the push button will feel a downward pre-pressing effect. Then, continue to push the push button and drive the slider to move up and down to push the limit shaft driving pin, so that the limit shaft is lifted and released, enabling the telescopic tube with the two-way unlocking component to enter the effect of adjusting the length. Then, push the inner tube to adjust to the required length, and the adjustment is relatively easy.

[0015] 2. During adjustment, due to the limited external settings with limit holes to prevent the telescopic tube of the bi-directional unlocking component from being damaged by excessive stretching or shortening, it can play a protective effect during adjustment. When not in use, like in the above situation, the limit shaft is lifted off, causing the device to contract or extend to achieve the required length. Its internal structure is simple, it can be unlocked in two directions, and it is relatively cheaper than the common telescopic tubes on the market. Moreover, with a simple internal structure, it has a longer service life and can be adjusted bidirectionally.

[0016] 3. In this utility model, when the positioning pin single piece is in use, due to its squeezable and resilient characteristic, the user can feel the adjustable position when squeezing it, which allows the user to adjust well during use. A rotation prevention groove is provided outside the inner tube to prevent the inner tube from rotating and causing trouble during use. When it rotates to a certain position, it will no longer be able to rotate, which can increase the service life of the telescopic rod. When adjusting the telescopic tube, the first limit hole and the second limit hole for controlling the retraction are provided to prevent excessive telescoping. The device has a simple structure and is durable. BRIEF DESCRIPTION OF THE DRAWINGS

A limiting shaft 3 for controlling the telescoping of the telescopic tube is arranged inside the push button 2. A positioning mechanism for fixing the length of the telescopic tube is arranged inside the push button 2. The positioning mechanism includes a positioning pin elastic piece 4 inside the push button 2, and the limiting shaft 3 is fixedly connected with the positioning pin elastic piece 4;

[0026] When adjusting the length, a limiting shaft driving pin 6 for making the device enter the adjustment is arranged outside the limiting shaft 3, and a slider 7 for pushing the limiting shaft driving pin 6 is arranged outside the limiting shaft 3. When the limiting shaft driving pin 6 is pushed by the slider 7, the limiting shaft 3 will be lifted and tripped. When the limiting shaft 3 is tripped, the inner tube 8 inside the outer tube 1 is adjusted relatively.

[0027] The working principle of a telescopic tube with a two-way unlocking component proposed by the present utility model is that when it is necessary to adjust the length of the telescopic tube, providing extrusion to the push button 2 will feel the effect of downward preloading. Then, continue to push the push button 2 and drive the slider 7 to move up and down to push the limiting shaft driving pin 6, so that the limiting shaft 3 is lifted and tripped, making the telescopic tube of the two-way unlocking component enter the effect of adjusting the length. Then, push the inner tube 8 to adjust to the required length. During the adjustment, since a limiting hole is arranged outside the inner tube 8 to prevent the inner tube 8 from being stretched too long or too short, which may damage the telescopic tube device of the two-way unlocking component, thus playing a protective role. When not in use, as described above, the limiting shaft 3 is lifted and tripped, so that the device contracts or extends to reach the required length.

[0028] Embodiment 2

[0029] As Figures 1-5 shown, based on Embodiment 1, the positioning pin elastic piece 4 has the characteristic of being able to be extruded and rebounded. An anti-rotation groove 11 for preventing rotation during length adjustment is arranged outside the inner tube 8. A first limiting hole 9 for controlling the length of retracting into the anti-rotation groove 11 is arranged outside the inner tube 8. Another set of control retracting second limiting holes 10 is arranged on the side of the inner tube 8 away from the first limiting hole 9. A joint 5 for the inner tube 8 to slide is arranged inside the anti-rotation groove 11, and the surface of the joint 5 has the effect of protecting the stable entry and exit of the inner tube 8.

[0030] Sliders 7 for pushing the limiting shaft driving pin 6 are symmetrically arranged inside the push button 2. The sliders facilitate the telescoping of the two-way telescopic tube. The push button 2 is slidably connected to the outer tube 1, and the push button 2 controls the telescopic tube under the sliding of the outer tube 1.

[0031] The working principle of a telescopic tube with a two-way unlocking component proposed by the present utility model is that the single-piece positioning pin 4 can feel the adjustable position when being squeezed by the user during use due to its squeezable and resilient characteristics, which can well allow the user to adjust during use. A rotation prevention groove 11 is provided outside the inner tube 8 to prevent the inner tube 8 from rotating and causing trouble during use. When rotated to a certain position, it will not be able to rotate, which can well increase the service life of the telescopic rod. When adjusting the telescopic tube, a first limiting hole 9 and a second limiting hole 10 for controlling indentation are provided to prevent excessive telescoping, making it durable and increasing the service life of the telescopic tube.
