Abstract
Description
Technical Field
[0001] This utility model relates to a conductive telescopic tube, belonging to the field of vacuum cleaner technology. Background Technology
[0002] Household vacuum cleaners come in many styles, but their basic structure is the same. They all contain a vacuum cleaner, a floor brush, and a suction tube connecting the floor brush and the main body of the vacuum cleaner. The suction tube contains conductive components. To meet cleaning needs, the suction tube usually has a telescopic function. Based on the material, suction tubes are divided into flexible tubes and rigid tubes. Flexible tubes are less reliable, prone to aging and breakage, and take up more space, making them less aesthetically pleasing. Rigid tubes are more reliable, more aesthetically pleasing, and more popular with consumers, showing a broad market prospect.
[0003] For rigid vacuum cleaner hoses, how to design a length adjustment scheme that satisfies both electrical reliability and ease of adjustment is a common concern. However, current adjustment mechanisms are either overly complex, cumbersome to operate, or lack reliability. Utility Model Content
[0004] To address the aforementioned shortcomings of existing technologies, this invention proposes a conductive telescopic tube that enables rapid unlocking and locking, possesses reliable locking and fixing capabilities, and improves operational convenience.
[0005] This utility model relates to a conductive telescopic tube, including a first tube segment and a second tube segment, wherein the second tube segment is sleeved on the first tube segment;
[0006] The first pipe section is provided with a locking groove, and the second pipe section is provided with an unlocking mechanism, which includes a button base, a button, a latch and a fixing block.
[0007] The button base is fixedly connected to the second pipe section. The button base is provided with a receiving groove, and the latch and fixing block are disposed in the receiving groove. Corresponding to the latch, the pipe wall of the second pipe section is provided with a latch through hole. A first spring is connected between the latch and the button, and a second spring is connected between the fixing block and the button.
[0008] When the latch is located in the locking groove, the first spring and the second spring are in a pre-compressed state; when the latch is disengaged from the locking groove, the first spring is in a stretched state.
[0009] Compared with the prior art, the present invention has the following technical effects:
[0010] The dual-spring structure design enables rapid locking and unlocking, provides reliable locking and fixing capabilities, and improves operational convenience. Attached Figure Description

It should be noted that in specific embodiments, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. Terms such as "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, unless otherwise explicitly defined, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0017] like Figure 1 As shown, an embodiment of the present invention relates to a conductive telescopic tube, including a first tube segment 100 and a second tube segment 200, the second tube segment 200 being sleeved on the first tube segment 100; the first tube segment 100 is provided with a plurality of locking grooves 101, and the second tube segment 200 is provided with an unlocking mechanism 500 corresponding to the locking grooves 101.
[0018] like Figure 2 and Figure 3 As shown, the unlocking mechanism 500 includes a button base 501, a button 502, a latch 503, a fixing block 504, a first spring 505, and a second spring 506.
[0019] The button base 501 is fixedly connected to the second pipe section 200. The button base 501 is provided with a receiving groove, and the latch 503 and the fixing block 504 are disposed in the receiving groove. Corresponding to the latch 503, the pipe wall of the second pipe section is provided with a latch through hole. A first spring 505 is connected between the latch 503 and the button 502, and a second spring 506 is connected between the fixing block 504 and the button 502. The second spring 506 is preferably a conical spring.
[0020] When the latch 503 is located in the locking groove 101, the first spring 505 and the second spring 506 are in a pre-compressed state; when the latch 503 is disengaged from the locking groove 101, the first spring 505 is in a stretched state, and the second spring 506 is in a partially stretched and partially compressed state.
[0021] In some preferred embodiments, the fixing block 504 and the button seat 501 are integrally formed or separately formed and then fixedly connected. Specifically, the fixing can be done by screwing, bonding, welding or other methods.
[0022] For some preferred implementation schemes, such as Figure 4 As shown, the first pipe section 100 has a slot 102 extending along its length, and a locking limit member 103 is provided in the slot 102. The locking groove 101 is formed on the locking limit member 103. The locking groove 101 can be a number of isolated points or they can be connected to each other.
[0023] Preferred, such as Figure 3 and Figure 4 As shown, the locking and limiting member 103 is provided with a locking block 104. Corresponding to the locking block 104, the second pipe section 200 is provided with a limiting block 201. When the first pipe section 100 and the second pipe section 200 are in the unlocked state, the limiting block 201 can abut against the locking block 104 to prevent the first pipe section 100 from completely separating from the second pipe section 200 during the free extension and retraction process.
[0024] In a further preferred embodiment, the limiting block 201 is fixed to the fixing block 504 by screws.
[0025] In some preferred embodiments, the first pipe section 100 is provided with a third pipe section 300, the second pipe section 200 is provided with a fourth pipe section 400, the fourth pipe section 400 is sleeved on the third pipe section 300 and sealed by annular elastic sponge; the first pipe section 100 and the second pipe section 200 serve as conductive sections, and the third pipe section 300 and the fourth pipe section 400 serve as dust collection sections.
[0026] Preferably, the first pipe segment 100 is provided with a first connector 105 at the end away from the second pipe segment 200, and a first conductor 107 is provided on the first connector 105; the second pipe segment 200 is provided with a second connector 202 at the end away from the first pipe segment 100, and a second conductor 204 is provided on the second connector 202. The first conductor 107 and the second conductor 204 are connected by a spring conductive connector, so that the first pipe segment 100 and the second pipe segment 200 serve as conductive segments.
[0027] It should be emphasized that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
