Detailed Description of the Preferred Embodiment
[0025] The following combines the attached drawings to describe in detail a specific embodiment of the present utility model, but it should be understood that the protection scope of the present utility model is not limited by the specific embodiment.
[0026] A detachable vacuum cleaner tube of the present utility model is as shown in Figure 1 and Figure 2 and at least includes a first pipe section 100 and a second pipe section 200. The first pipe section 100 and the second pipe section 200 are detachably connected through a joint mechanism. The joint mechanism includes a first mating joint 300 and a second mating joint 400 respectively arranged at the opposite ends of the adjacent first pipe section 100 and the second pipe section 200. The first mating joint 300 and the second mating joint 400 are locked and connected through a locking mechanism.
[0027] As shown in Figure 2 and Figure 3As shown, the first mating joint 300 includes a main body portion 310 fixedly sleeved on the rear end portion of the first pipe section 100, and an insertion pipe portion 320 provided on the rear end face of the main body portion 310 and axially extending backward. A locking groove 321 structure is formed on the outer wall of the insertion pipe portion 320. On the rear end face of the main body portion 310 corresponding to the outside of the insertion pipe, a receiving cavity 311 axially extending forward is formed. A pushing member 312 is movably and limitably installed in the receiving cavity 311, and a first elastic member 313 is provided between the front end portion of the pushing member 312 and the front cavity wall of the receiving cavity 311. The first elastic member 313 causes the rear end portion of the pushing member 312 to always have a tendency to move backward and extend out of the rear end face of the main body portion 310. The first elastic member 313 is preferably a spring.
[0028] As Figure 2 and Figure 3 As shown, an insertion cavity 411 for inserting the insertion pipe portion 320 of the first mating joint 300 is formed in the second mating joint 400. The front end face of the second mating joint 400 is used to engage with the rear end face of the main body portion 310. The rear end of the second mating joint 400 is fixedly sleeved on the front end portion of the second pipe section 200. A locking member 430 is pivotally installed on the second mating joint 400. The front end of the locking member 430 has a hook portion 431 for hooking with the locking groove 321, and the rear end is a pressing portion 432. A second elastic member 433 that causes the pressing portion 432 to always have a tendency to tilt upward is provided at the position corresponding to the pressing portion 432 of the locking member 430. The second elastic member 433 is preferably a spring.
[0029] In this way, when the first mating joint 300 and the second mating joint 400 are connected in cooperation, the insertion pipe portion 320 of the first mating joint 300 is inserted into the insertion cavity 411 of the second mating joint 400, and the front end face of the second mating joint 400 is attached to the rear end face of the main body portion 310 to press the pushing member 312 on the rear end face into the receiving cavity 311. At this time, the first elastic member 313 (spring) is compressed to store elastic potential energy. At the same time, the hook portion 431 of the locking member 430 on the second mating joint 400 is hooked with the locking groove 321 on the first mating joint 300 and is stably connected under the action of the second elastic member 433 (spring) to limit the axial separation between the first mating joint 300 and the second mating joint 400. When the pressing portion 432 of the locking member 430 is pressed to make the hook portion 431 tilt up to unlock, the potential energy stored in the first elastic member 313 is converted into kinetic energy to push the pushing member 312 to move outward, so as to push the second mating joint 400 away to achieve separation from the first mating joint 300, thereby effectively facilitating the disassembly between the pipe sections of the vacuum cleaner tube.
[0030] In this embodiment, as Figure 3As shown, a guiding sliding groove 3111 extending axially is preferably provided at the bottom of the accommodating cavity 311. A guiding protrusion 3121 corresponding to the bottom surface of the elastic pushing member 312 is embedded in the guiding sliding groove 3111 and can slide along the guiding sliding groove 3111. The cooperation of the guiding sliding groove 3111 and the guiding protrusion 3121 not only effectively limits the movement stroke of the elastic pushing member 312, avoiding the elastic pushing member 312 from detaching from the accommodating cavity 311, but also ensures the reliability of the sliding movement of the elastic pushing member 312.
[0031] In this embodiment, as Figure 2 and Figure 4 shown, the locking groove 321 on the cannula portion 320 is preferably formed by two limiting ribs 322 extending axially at intervals along the outer wall of the cannula portion 320 and a connecting rib 323 connecting the rear ends of the two limiting ribs 322. The connecting rib 323 is used to hook with the hook portion 431 of the locking member 430 to limit axial separation; the insertion cavity 411 of the second fitting joint 400 includes a limiting notch 412 that cooperates with the protruding locking structure. The cooperation of the limiting notch 412 and the limiting ribs 322 can effectively limit the rotation between the first fitting joint 300 and the second fitting joint 400; preferably, the outer side wall surfaces of the two limiting ribs 322 are inclined surfaces arranged in an inverted "eight" shape, and the angle formed by the outer side wall surface of the limiting rib 322 and the vertical plane is 10° - 15°. The inner side wall surfaces of both sides of the limiting notch 412 are inclined surfaces arranged in a right-side-up "eight" shape, and the angle formed by the inner side wall surface of the limiting notch 412 and the vertical plane is 10° - 15°. In this way, when the first fitting joint 300 and the second fitting joint 400 rotate relative to each other, it can achieve the effect of getting tighter and tighter, thereby greatly improving the cooperation stability and reliability.
[0032] In this embodiment, as Figure 3As shown, the second mating joint 400 includes an inner housing 410 having a structure of an insertion cavity 411, and an outer housing 420 fixedly provided outside the inner housing 410; a rotation connection seat is constructed and arranged on the outer wall of the inner housing 410 corresponding to the position of the limiting notch 412, and both sides of the middle of the locking member 430 are rotatably installed in the rotation connection seat through a rotating shaft. A first opening is correspondingly formed on the bottom wall of the limiting notch 412 for the hook portion 431 to extend into and hook with the mating structure on the insertion tube portion 320; a second opening is formed on the outer housing 420 corresponding to the pressing portion 432 of the locking member 430, and a key 421 is rotatably installed in the second opening of the outer housing 420. During the process of pressing the key 421 downward, it can act on the pressing portion 432 of the locking member 430 to cause the hook portion 431 at the other end to tilt up to achieve unlocking; preferably, in the absence of external force, the pressing portion 432 of the key 421 tilted up under the pushing action of the second elastic member 433 just engages with the wall surface of the outer housing 420 to block the second opening, thus greatly improving the integrity and aesthetics of the second mating joint 400.
[0033] In this embodiment, preferably, the rear end surface of the main body portion 310 and the front end surface of the second mating joint 400 are adapted inclined surface structures, so as to facilitate the directional insertion of the two joints.
[0034] Compared with the prior art, the structure of the present utility model is simple and reasonable. The cooperation between the limiting ribs with an inverted eight-shaped structure and the limiting notches with a positive eight-shaped structure between adjacent pipe segments can effectively limit the rotation between the pipe segments, effectively improving the cooperation reliability and stability between the pipe segments; at the same time, when unlocking adjacent pipe segments of the vacuum cleaner pipe, they can be automatically axially separated under the pushing action of the compressed elastic pushing member, thereby effectively simplifying the disassembly and separation between the pipe segments of the vacuum cleaner pipe.
[0035] The above-disclosed are only the embodiments of the present utility model. However, the present utility model is not limited thereto, and any changes that can be thought of by those skilled in the art should fall within the protection scope of the present utility model.
