DETAILED DESCRIPTION

[0026] In order to make the technical personnel in the art better understand the technical scheme of the utility model, the utility model will be further explained in detail below in combination with specific implementation manners.

[0027] Please refer to Figures 1-5As shown, the embodiment of the present application provides a bounce core assembly, comprising: an axially extending housing member 1, which is provided with a connecting portion 13; a transmission assembly arranged in the housing member 1, which comprises coaxially arranged driving member 2, rotating member 3 and elastic member (not shown in the figure), the driving member 2 comprises axially distributed connecting end 21 and driving end, the connecting end 21 penetrates through the housing member 1; the driving end is axially slidingly fitted in the housing member 1, the driving end is circumferentially provided with a plurality of axially extending convex tooth portions 24, the rotating member 3 is circumferentially provided with a plurality of guiding portions 32 which are transmissionally matched with the convex tooth portions 24, the guiding portions 32 have first inclined surfaces 33 which are obliquely arranged to match the convex tooth portions 24 to rotate the transmission rotating member 3, so that the rotating member 3 is switched between the first working position and the second working position by the transmission of the driving member 2; the inner wall of the housing member 1 is circumferentially provided with a plurality of first limiting grooves 113 and second limiting grooves 112 which are alternately distributed and are used for clamping the guiding portions 32, the first limiting grooves 113 corresponding to the first working position are longer than the second limiting grooves 112 corresponding to the second working position in the axial direction, the slot openings of the first limiting grooves 113 and the second limiting grooves 112 are all provided with second inclined surfaces 111 which are matched with the first inclined surfaces 33; the elastic member is arranged between the rotating member 3 and the inner wall of the housing member 1.

[0028] The connecting part 13 of the shell member 1 is used to connect the lower part of the water drainer, and the connecting end 21 of the driving member 2 is used to connect the sealing cover of the water drainer, and the opening and closing of the drain hole by the sealing cover can be realized by the state switching of the elastic core assembly. The driving member 2 of the transmission assembly can be extended or retracted in the axial direction of the shell member 1, and the convex tooth part 24 of the driving end can facilitate the transmission cooperation with the first inclined surface 33 of the guide part 32 of the rotating member 3, that is, when the driving member 2 is pressed, the driving member 2 can make the convex tooth part 24 press the first inclined surface 33 of the guide part 32 of the rotating member 3 through the axial movement, and push the guide part 32 of the rotating member 3 out of the first limiting groove 113 or the second limiting groove 112, at this time, since the rotating member 3 is in a movable state, the axial force can be mainly decomposed into a rotating force under the action of the force decomposition of the first inclined surface 33, and then the rotating member 3 can rotate, and the rotating member 3 can facilitate the guide part 32 to be clamped into the next first limiting groove 113 or second limiting groove 112 through rotation, and the first limiting groove 113 and the second limiting groove 112 are different in depth or length in the axial direction, so that the rebound position of the rotating member 3 under the elastic force of the elastic member can be restricted, and the switching of the rotating member 3 between the first working position and the second working position can be realized. At the same time, since the slot of the first limiting groove 113 and the second limiting groove 112 is provided with the second inclined surface 111 matched with the first inclined surface 33, the slot can form a structure matched with the guide part 32, and the guide part 32 can be more conveniently clamped in place in the first limiting groove 113 and the second limiting groove 112. In this way, the transmission cooperation of the driving member 2 and the rotating member 3 can avoid the transmission structure of the lock hook, and higher strength can be obtained, and the service life is improved.

[0029] Through the above technical solution, the transmission cooperation of the driving member 2 and the rotating member 3 can convert the axial force into a rotating force capable of rotating the rotating member 3 through the transmission cooperation of the convex tooth part 24 on the driving end and the guide part 32 on the rotating member 3 under the pressure of the driving member 2, and the guide part 32 on the rotating member 3 can be alternately clamped into the first limiting groove 113 and the second limiting groove 112 through the rotation of the rotating member 3, and then the driving member 2 can be driven to perform the elastic jumping action through the switching of the working position of the rotating member 3, so that the opening and closing state switching of the water drainer can be facilitated, and the transmission structure without the lock hook can have better strength and longer service life.

[0030] In an embodiment, when the guide part 32 is in the first limiting groove 113, the elastic core assembly is in a contracted state, and when the guide part 32 is in the second limiting groove 112, the elastic core assembly is in an elongated state.

[0031] In this way, the rotating guide portion 32 can switch the state of the bouncing core assembly when moving between the first limiting groove 113 and the second limiting groove 112, and through the first limiting groove 113 and the second limiting groove 112 alternately distributed in the circumferential direction, the rotation can be sequentially clamped into the first limiting groove 113 and the second limiting groove 112, thereby realizing the back-and-forth switching of the state.

[0032] Further, the driving member 2 is in a cylindrical structure, the rotating member 3 is in a columnar structure and extends into the driving member 2 in the axial direction, and the driving member 2 and the rotating member 3 are axially fixed or have a predetermined movable length in the axial direction which is smaller than the distance between the first working position and the second working position.

[0033] In this way, the driving member 2 can be sleeved outside the rotating member 3 and be extended or retracted with the position switching of the rotating member 3. In the specific implementation process, the driving member 2 can be axially fixed with the rotating member 3, i.e., cannot move relative to the rotating member 3 in the axial direction, so that the driving member 2 and the rotating member 3 can move synchronously to realize the position switching in the axial direction. The driving member 2 can also have a certain activity in the axial direction with the rotating member 3, such as the movable length of the driving member 2 and the rotating member 3 in the axial direction is smaller than the distance between the first working position and the second working position, so that the driving member 2 can also be convenient to move with the rotating member 3. In the retracted state, the driving member 2 will also be retracted due to the gravity of the sealing cover, but can also be extended by artificial pulling, so that the sealing cover can be pulled out for cleaning the drain hole when damage or locking failure occurs.

[0034] In order to realize the assembly of the driving member 2 and the rotating member 3, further, a clamping hole 22 in communication with the inner cavity of the driving member 2 is arranged in the connecting end 21 of the driving member 2, and an elastic clamping tongue 31 is arranged at one end of the rotating member 3 away from the guide portion 32, the elastic clamping tongue 31 penetrates into the clamping hole 22 and is clamped and matched with the clamping hole 22.

[0035] In this way, the elastic clamping tongue 31 on the rotating member 3 can be inwardly retracted by pressure deformation, and can be clamped into the clamping hole 22 when retracted, and can be outwardly rebounded and reset by releasing the elastic force after being clamped into the clamping hole 22, thereby realizing clamping and fixing through the cooperation of the elastic clamping tongue 31 and the clamping hole 22. Specifically, the end of the elastic clamping tongue 31 is provided with a clamping head, the end of the clamping head is provided with an inclined guide surface, the guide surface can be conveniently clamped into the clamping hole 22, and the clamping hole 22 is a stepped hole structure, after the elastic clamping tongue 31 is clamped, the clamping head can be clamped and matched with the clamping hole 22 structure of the stepped structure, thereby realizing clamping and fixing, so as to facilitate assembly and disassembly. For disassembly, the elastic clamping tongue 31 can be inwardly retracted by a disassembly tool to realize disassembly.

[0036] In order to facilitate the stable axial sliding of the driving member 2, the driving member 2 is provided with a guide sliding block 23 slidingly fitted in the first limiting groove 113. Through the cooperation of the guide sliding block 23 and the first limiting groove 113, the driving member 2 can be conveniently extended and retracted for a long distance, and the driving member 2 can be prevented from rotating.

[0037] In a preferred embodiment of the housing member 1, the housing member 1 comprises a connecting cylinder 11 and a connecting seat 12, the connecting cylinder 11 and the connecting seat 12 are threadedly connected and form an inner cavity accommodating the transmission assembly, and the first limiting groove 113 and the second limiting groove 112 are arranged on the inner wall of the connecting cylinder 11.

[0038] The threaded connection of the connecting cylinder 11 and the connecting seat 12 can realize the detachability of the housing, thereby facilitating maintenance or replacement, and being more convenient and practical. By arranging the first limiting groove 113 and the second limiting groove 112 on the inner wall of the connecting cylinder 11, separate components for arranging the first limiting groove 113 and the second limiting groove 112 can be avoided, the structure is more optimized, and the number of parts is less.

[0039] Specifically, the connecting portion 13 and the connecting end 21 are both threaded connection structures. Through the threaded connection structure, the assembly and connection with other components of the drain can be facilitated, and the disassembly is also facilitated, which is more convenient.

[0040] Preferably, the driving member 2, the rotating member 3 and the housing member 1 are all made of plastic material. The plastic material is PVC plastic, which can have good corrosion resistance, longer service life, and lower cost compared with copper material.

[0041] The elastic member is a spring.

[0042] The above is only a preferred embodiment of the present application, and it should be pointed out that the above preferred embodiment should not be regarded as limiting the present application, and the protection scope of the present application should be limited by the scope defined in the claims. For ordinary skilled in the art, some improvements and refinements can be made without departing from the spirit and scope of the present application, and these improvements and refinements should also be regarded as the protection scope of the present application.
