Description

Technical Field

[0001] The utility model relates to the technical field of movable telescopic tubes of vacuum cleaners, in particular to a telescopic tube of a vacuum cleaner. Background Art

[0002] There are many styles of household vacuum cleaners, but the basic structure is the same. They all contain a vacuum cleaner, a floor brush, and a vacuum tube connecting the floor brush and the vacuum cleaner body. Conductive components are arranged in the vacuum tube. In order to meet the needs of cleaning, the vacuum tube usually has a telescopic function. The vacuum cleaner telescopic tube is an important component of the vacuum cleaner. The vacuum cleaner handle is connected to the floor brush through the vacuum cleaner telescopic tube, thus forming the entire vacuum cleaner accessory.

[0003] According to a disclosed telescopic tube of a vacuum cleaner (publication number: 220001644U), it includes a No. 1 fixed tube, an adjustment tube and a locking assembly, and the locking assembly includes a locking button, a cross-shaped connecting block, a square locking block, a fixing sleeve, a reset spring and a metal sheet; the fixing sleeve is mounted on the No. 1 fixed tube, and the locking button is pivotally connected to the fixing sleeve to form a flip structure; the rear end face of the square locking block is integrally formed with an anti-detachment buckle, and the top surface of the anti-detachment buckle is an inwardly inclined inclined surface. It is difficult to effectively perform the semi-automatic and quick telescopic function in the above application documents, and the operation during telescopic operation is relatively troublesome. Utility Model Content

[0004] In order to solve the problem that the prior art is troublesome during extension and retraction, the utility model provides a telescopic tube of a vacuum cleaner, which can perform semi-automatic, fast and convenient extension and retraction.

[0005] A telescopic tube for a vacuum cleaner comprises an outer tube 1 and an outer tube 2, wherein the rear end of the outer tube 1 is plugged and slidably connected to the inner side of the front end of the outer tube 2.

[0006] The surfaces of the outer tube one and the outer tube two are both provided with movable devices, and the movable devices include a positioning block, the top of the positioning block is fixedly connected to the inner surface of the front end of the outer tube two, the bottom of the positioning block is slidably connected with an L-shaped slide groove, the surface of the L-shaped slide groove is opened on the outer surface of the rear end of the outer tube one, the front end surface of the outer tube two is fixedly connected with a round rod, the side surface of the round rod away from the outer tube two is slidably connected with a hollow sleeve, the surface of the hollow sleeve is fixedly connected to the surface of the circular ring, the inner wall of the circular ring is rotatably connected with an annular groove, and the annular groove is opened on the surface of the outer tube one.

[0007] Furthermore, a pressure spring is provided inside the hollow sleeve, one end of the pressure spring is fixedly connected to the surface of the round rod, and the other end is fixedly connected to the inner wall of the hollow sleeve. When the telescopic device is subjected to external force, the round rod will move relative to each other, causing the pressure spring to be compressed. Since the pressure spring is an elastic element, it will store energy. When the external force decreases or disappears, the spring releases the stored energy to push the round rod to return to its original position. The presence of the pressure spring can provide a certain degree of buffering and shock absorbing effect. When the telescopic device moves or is impacted externally, the pressure spring can absorb and mitigate part of the impact force, reduce the impact on the device and other components, thereby protecting the stability and life of the system.

[0008] Furthermore, the L-shaped slide groove and positioning block, round rod, hollow sleeve, and pressure spring are arranged in three groups, and each group is evenly distributed on the surface of outer tube one and outer tube two. By evenly distributing the three components of L-shaped slide groove and positioning block, round rod, hollow sleeve and pressure spring on the surface of outer tube one and outer tube two, it helps to enhance the overall stability of the telescopic device. Evenly distributing these components, especially round rod, pressure spring and L-shaped slide groove, on the surface of outer tube one and outer tube two can achieve balance of the telescopic device. This balance helps to maintain uniform distribution of force during telescoping, avoid unnecessary stress concentration, and extend the service life of the device.

[0009] Furthermore, a protective positioning device is provided on the outer surface of the movable device, and the protective positioning device includes a snap ring 1 and a snap ring 2, and the opposite surfaces of the snap ring 1 and the snap ring 2 are fixedly connected with soft adhesive tape, the top of the snap ring 1 is fixedly connected with an L-shaped support block 1, and the top surface of the snap ring 2 is fixedly connected with an L-shaped support block 2.

[0010] Furthermore, the inner wall of the clamping ring 1 is fixedly connected to the front end surface of the outer tube 2, and the inner wall of the clamping ring 2 is fixedly connected to the front end surface of the hollow sleeve, thereby ensuring that the relative movement between the front end surface of the outer tube 2 and the front end surface of the hollow sleeve is smooth and orderly, which is crucial to the smooth operation and user experience of the telescopic tube. The fixed connection between the inner walls of the clamping ring 1 and the clamping ring 2 and the front end surfaces of the outer tube 2 and the hollow sleeve helps to ensure the firmness, coordinated movement and integrity of the structure, thereby improving the performance and service life of the telescopic tube.

[0011] Furthermore, the relative surfaces of the L-shaped support block one and the L-shaped support block two are respectively provided with positive magnetic blocks and negative magnetic blocks. When the positive magnetic blocks and the negative magnetic blocks on the relative surfaces of the L-shaped support block one and the L-shaped support block two come into contact, they will be magnetically adsorbed. The adsorption effect can help ensure the precise alignment of the L-shaped support blocks, providing a reliable positioning mechanism.

[0012] The difference from the prior art is that the beneficial effects of this application are:

[0013] (1) The telescopic tube of the vacuum cleaner moves along the inner wall of the L-shaped slide groove through the positioning block on the inner side of the front end of the outer tube. The round rod on the front end surface of the outer tube slides in the hollow sleeve and can slide. When the front end of the outer tube and the head parts are working on the ground, the personnel hold the rear end surface of the outer tube to control it. By rotating the outer tube, the positioning block is transferred into the hook of the L-shaped slide groove to perform a minimum size collection and fixation, so as to help the automatic telescopic effect according to the needs of the personnel.

[0014] (2) The telescopic tube of the vacuum cleaner rotates and drives the L-shaped support block 2 and the L-shaped support block 1 on the surfaces of the clamp ring 1 and the clamp ring 2 to fit together, and uses the positive magnetic block and the negative magnetic block on the opposite surfaces thereof for adsorption. At the same time, the software cloth on the opposite surfaces of the clamp ring 1 and the clamp ring 2 is used to protect the entire parts, so as to achieve a simple fixing effect when folded.

[0030] See also Figure 1-Figure 4 As shown in the figure, a telescopic tube of a vacuum cleaner includes an outer tube 100 and an outer tube 200. The rear end of the outer tube 100 is plugged and slidably connected to the inner side of the front end of the outer tube 200.

[0031] First, the surfaces of the outer tube 100 and the outer tube 200 are both provided with movable devices 500. When the movable device 500 includes a positioning block 505, and the top of the positioning block 505 is fixedly connected to the inner surface of the front end of the outer tube 200, the bottom of the positioning block 505 is slidably connected with an L-shaped slide groove 504, and the surface of the L-shaped slide groove 504 is opened on the outer surface of the rear end of the outer tube 100, the front end surface of the outer tube 200 is fixedly connected with a round rod 502, and the side surface of the round rod 502 away from the outer tube 200 is slidably connected with a hollow sleeve 501, and the inner surface of the hollow sleeve 501 is connected to the outer tube 200. A pressure spring 503 is provided at the bottom, and one end of the pressure spring 503 is fixedly connected to the surface of the round rod 502, and the other end is fixedly connected to the inner wall of the hollow sleeve 501. When the telescopic device is subjected to an external force, the round rod 502 will move relative to it, causing the pressure spring 503 to be compressed. Since the pressure spring 503 is an elastic element, it will store energy. When the external force decreases or disappears, the spring releases the stored energy and pushes the round rod 502 to return to its original position. The existence of the pressure spring 503 can provide a certain degree of buffering and shock absorption effect. When there is an impact or external shock, the pressure spring 503 can absorb and slow down part of the impact force, reduce the impact on the device and other components, and thus protect the stability and life of the system. The surface of the hollow sleeve 501 is fixedly connected to the surface of the ring 506. The L-shaped slot 504 and the positioning block 505, the round rod 502, the hollow sleeve 501, and the pressure spring 503 are arranged in three groups, and each group is evenly distributed on the surface of the outer tube 100 and the outer tube 200. By connecting the L-shaped slot 504 and the positioning block 505, the round rod 502, the hollow sleeve 501 and the pressure spring 503 The components are evenly distributed on the surface of the outer tube 100 and the outer tube 200, which helps to enhance the overall stability of the telescopic device. Evenly distributing these components, especially the round rod 502, the pressure spring 503 and the L-shaped groove 504, on the surface of the outer tube 100 and the outer tube 200 can achieve the balance of the telescopic device. This balance helps to maintain uniform distribution of force during telescoping, avoid unnecessary stress concentration, and extend the service life of the device. The inner wall of the ring 506 is rotatably connected to a ring groove 507, and the ring groove 507 is opened on the surface of the outer tube 100.

[0032] When in use, when a person uses the equipment, he first moves along the inner wall of the L-shaped slide groove 504 through the positioning block 505 on the inner side of the front end of the outer tube 200 to help adjust the maximum length and the minimum length between the outer tube 1 100 and the outer tube 200. At the same time, the round rod 502 on the front end surface of the outer tube 200 slides in the hollow sleeve 501 and can slide. Here, the pressure spring 503 is used inside the hollow sleeve 501 to help the round rod 502 to exert a unidirectional supporting force in the hollow sleeve 501. At the same time, when a person uses the equipment, when the front end of the outer tube 100 and the head parts are working on the ground, the person holds the rear end surface of the outer tube 200 for control. Here, when the outer tube 100 is in small contact with the ground, When in contact at 90 degrees, outer tube 1 100 and outer tube 2 200 use the retraction of hollow sleeve 501 and round rod 502 to retract the length. When it is greater than 90 degrees, pressure spring 503 is used to help outer tube 1 00 and outer tube 200 increase the length. At the same time, when it needs to be folded, the equipment is perpendicular to the ground and a downward pressure is applied. When the positioning block 505 moves in the L-shaped slide groove 504, when it moves to the front end, the positioning block 505 is transferred into the hook of the L-shaped slide groove 504 by rotating outer tube 200 to perform a minimum size collection and fixation to reduce the storage space. It is explained here that while outer tube 200 is rotating, the round rod 502 is used to drive the hollow sleeve 501 to perform a synchronous rotation in the ring groove 507 through the ring 506.

[0033] At the same time, in order to protect the equipment parts when the equipment is in use, please refer to Figure 1-Figure 4As shown in the figure, a protective positioning device 600 is provided on the outer surface of the movable device 500, and the protective positioning device 600 includes a clamp ring 1 601 and a clamp ring 2 607, and the inner wall of the clamp ring 1 601 is fixedly connected to the front end surface of the outer tube 200, and the inner wall of the clamp ring 2 607 is fixedly connected to the front end surface of the hollow sleeve 501, which can ensure that the relative movement between the front end surface of the outer tube 200 and the front end surface of the hollow sleeve 501 is smooth and orderly, which is crucial to the smooth operation and user experience of the telescopic tube. When the inner walls of the clamp ring 1 601 and the clamp ring 2 607 are fixedly connected to the front end surfaces of the outer tube 200 and the hollow sleeve 501, it helps to ensure the firmness of the structure and the coordinated movement. And integrity, thereby improving the performance and service life of the telescopic tube, the opposite surfaces of the clamp ring 1 601 and the clamp ring 2 607 are fixedly connected with soft tape 606, the top of the clamp ring 1 601 is fixedly connected with an L-shaped support block 1 602, and the opposite surfaces of the L-shaped support block 1 602 and the L-shaped support block 2 603 are respectively provided with a positive magnetic block 604 and a negative magnetic block 605, when the positive magnetic block 604 and the negative magnetic block 605 on the opposite surfaces of the L-shaped support block 1 602 and the L-shaped support block 2 603 are in contact, they will be magnetically adsorbed, and the adsorption effect can help ensure the precise alignment of the L-shaped support blocks, providing a reliable positioning mechanism, and the top surface of the clamp ring 2 607 is fixedly connected with the L-shaped support block 2 603.

[0034] During use, when the device is rotated and folded, the L-shaped support block 2 603 and the L-shaped support block 1 602 on the surface of the snap ring 1 601 and the snap ring 2 607 are rotated and driven to fit together. It is noted here that the positions of the L-shaped support block 2 603 and the L-shaped support block 1 602 are staggered in the working state. When fitting together, the positive magnetic block 604 and the negative magnetic block 605 on the opposite sides are used for adsorption to achieve a convenient positioning effect. At the same time, the software cloth 606 on the opposite sides of the snap ring 1 601 and the snap ring 2 607 is used to protect the overall parts.
