[0022] The present application will be further described in detail below in conjunction with the drawings and specific embodiments.

[0023] Referring to Figures 1-4 As shown in the drawings, the embodiments of the present application disclose a telescopic tissue box, which comprises a connecting ring 1, an upper cover assembly 2 and a base assembly 3. The lower end of the upper cover assembly 2 is vertically and slidably sleeved on the outside of the upper end of the connecting ring 1, and the upper end of the base assembly 3 is vertically and slidably sleeved on the outside of the lower end of the connecting ring 1. The connecting ring 1, the upper cover assembly 2 and the base assembly 3 form a cavity for containing tissues, and the middle part of the upper end of the upper cover assembly 2 is provided with a tissue outlet 20.

[0024] Both the upper and lower outer walls of the connecting ring 1 are provided with annular retaining edges 11 that protrude radially from the connecting ring 1. The annular retaining edge 11 at the upper end of the connecting ring 1 abuts against the lower end of the upper cover assembly 2 to prevent the upper cover assembly 2 from detaching from the connecting ring 1, and the annular retaining edge 11 at the lower end of the connecting ring 1 abuts against the upper end of the base assembly 3 to prevent the base assembly 3 from detaching from the connecting ring 1. With this structure, under the action of the annular retaining edges at the upper and lower ends of the connecting ring, the annular retaining edge at the upper end of the connecting ring can abut against the lower end of the upper cover assembly to prevent the upper cover assembly from detaching from the connecting ring, and the annular retaining edge at the lower end of the connecting ring can abut against the upper end of the base assembly to prevent the base assembly from detaching from the connecting ring. This allows the upper cover assembly and the base assembly to be reliably assembled with the connecting ring and effectively prevents the upper cover assembly and the base assembly from detaching from the connecting ring.

[0025] The top cover assembly 2 includes an upper sliding ring 21 and a top cover 22. The upper sliding ring 21 is vertically slidably sleeved on the outside of the connecting ring 1. The lower end of the top cover 22 is vertically slidably sleeved on the outside of the upper end of the connecting ring 1 and connected to the upper sliding ring 21. The paper drawer opening 20 is located in the middle of the upper end of the top cover 22. The annular retaining edge 11 located at the upper end of the connecting ring 1 is used to abut against the upper sliding ring 21 to prevent the top cover assembly 2 from detaching from the connecting ring 1. With this structure, under the sliding cooperation between the upper sliding ring and the connecting ring, the top cover can be reliably vertically slidably connected to the upper end of the connecting ring. In addition, when the upper sliding ring slides to the upper limit position, the upper sliding ring can abut against the annular retaining edge located at the upper end of the connecting ring to prevent the top cover from detaching from the connecting ring.

[0026] The inner wall of the lower end of the top cover 22 is provided with a number of first locking blocks 221 circumferentially, and the outer wall of the upper sliding ring 21 is provided with a number of first locking grooves 211 circumferentially. Each first locking block 221 is engaged with the first locking groove 211 at the corresponding position. With this structure, the lower end of the top cover can be reliably engaged with the upper sliding ring, which means that the assembly of the top cover and the upper sliding ring can be achieved conveniently and reliably.

[0027] The base assembly 3 includes a sliding ring 31 and a base 32. The sliding ring 31 is vertically slidably sleeved on the outside of the connecting ring 1, and the upper end of the base 32 is vertically slidably sleeved on the outside of the lower end of the connecting ring 1 and connected to the sliding ring 31. The annular retaining edge 11 located at the lower end of the connecting ring 1 is used to abut against the sliding ring 31 to prevent the base assembly 3 from detaching from the connecting ring 1. With this structure, under the sliding cooperation between the sliding ring and the connecting ring, the base can be reliably vertically slidably connected to the lower end of the connecting ring. In addition, when the sliding ring slides to the lower limit position, the sliding ring can abut against the annular retaining edge located at the lower end of the connecting ring to prevent the base from detaching from the connecting ring.

[0028] The base 32 includes a support ring 321 and a base plate 322. The upper end of the support ring 321 is vertically slidably sleeved on the outside of the lower end of the connecting ring 1 and connected to the sliding ring 31. The base plate 322 is detachably fastened to the lower end of the support ring 321. With this structure, after the base plate is detached from the support ring, the user can easily place the tissue into the cavity formed by the connecting ring, the top cover assembly and the base assembly. After the tissue is placed into the cavity, the base plate can be fastened to the lower end of the connecting ring.

[0029] The outer edge of the base plate 322 is provided with several hand slots 3221. With the hand slots provided, when the base plate needs to be removed from the support ring, the user can insert his fingernail or other object into the hand slot and turn the base plate so that the base plate can be removed from the support ring.

[0030] The upper inner wall of the support ring 321 is provided with several second locking blocks 3211 circumferentially, and the outer wall of the sliding ring 31 is provided with several second locking slots 311 circumferentially. Each second locking block 3211 is engaged with the corresponding second locking slot 311. With this structure, the upper end of the support ring can be reliably engaged with the sliding ring, which means that the assembly of the base and the sliding ring can be achieved conveniently and reliably.

[0031] The outer wall of the connecting ring 1 is provided with several grooves 12 in the circumferential direction. Each groove 12 extends in the vertical direction, and both ends of each groove 12 extend to the upper end and the lower end of the connecting ring 1, respectively. By adopting this structure, when the upper cover assembly and the base assembly slide vertically relative to the connecting ring, the contact area between the upper cover assembly and the base assembly and the outer wall of the connecting ring can be reduced, that is, the static friction between the upper cover assembly and the base assembly and the connecting ring can be reduced, thereby making the vertical sliding of the upper cover assembly and the base assembly relative to the connecting ring smoother.

[0032] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
