DETAILED DESCRIPTION

[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments; however, the fast-adjustable fixing device and bathroom equipment having the same of the present invention are not limited to the embodiments.

[0039] For examples, see Figures 3 to 9 As shown, a fast-adjustable fixing device of the present invention is used to fix a part to be fixed (not shown), comprising:

[0040] Fixed frame 1;

[0041] The locking unit 2 is mounted on the fixing frame 1. The locking unit 2 includes a positioning member 22 and a locking member 23 fixed relative to the fixing frame 1. The locking member 23 is provided with an inserting hole 231. The inner wall of the inserting hole 231 is provided with at least one first meshing portion 232 and at least one first yielding portion 233. The first meshing portion 232 and the first yielding portion 233 are alternately arranged along the circumference of the inserting hole 231.

[0042] The connecting member 3 is plugged into and matched with the plug hole 231 and can rotate between the locking position and the unlocking position relative to the locking member 23. The positioning member 22 is linked with the connecting member 3. When the connecting member 3 is rotated to the locking position and the unlocking position, the positioning member 22 is used to realize rotation positioning relative to the fixing frame 1. The outer wall of the connecting member 3 is provided with at least one second meshing portion 31 that can mesh with the first meshing portion 232 and at least one second yielding portion 32. The second meshing portion 31 and the second yielding portion 32 are alternately arranged along the circumference of the connecting member 3, and the fixing member is connected to the connecting member 3;

[0043] When the connecting member 3 is in the locking position, the first meshing portion 232 meshes with the second meshing portion 31 to lock the connecting member 3; when the connecting member 3 is in the unlocking position, the first yielding portion 233 yields to the second meshing portion 31, and the second yielding portion 32 yields to the first meshing portion 232, so that the connecting member 3 can move axially relative to the locking unit 2 along the plug-in hole 231.

[0044] Specifically, in this embodiment, two oppositely arranged first meshing portions 232 and two oppositely arranged first yielding portions 233 are provided on the inner wall of the plug-in hole 231, and the first meshing portions 232 and the first yielding portions 233 are alternately arranged along the circumference of the plug-in hole 231; the connecting member 3 is a connecting rod, and two oppositely arranged second meshing portions 31 and two oppositely arranged second yielding portions 32 are provided on the outer wall of the connecting member 3, and the second meshing portions 31 and the second yielding portions 32 are alternately arranged along the circumference of the connecting member 3; the first meshing portion 232 and the second meshing portion 31 are threaded portions that can mesh with each other, the first yielding portion 233 is a smooth curved surface, and the second yielding portion 32 is a smooth plane. The connecting member 3 and the positioning member 22 are rotatably linked. When the connecting member 3 rotates between the locking position and the unlocking position, it drives the positioning member 22 to rotate between the first position and the second position relative to the fixed frame. The locking unit 2 also includes a limiting structure. When the positioning member 22 rotates to the first position and the second position, rotational positioning is achieved through the limiting structure.

[0045] See also Figures 7 and 8 In this embodiment, the locking unit 2 further comprises a fixed body 21 fixedly mounted on the fixing frame 1 and provided with an accommodating cavity (not shown in the figure) inside, and the positioning member 22 is rotatably arranged in the accommodating cavity of the fixed body 21 between the first position and the second position. The locking member 23 is fixed in the accommodating cavity, and the locking member 23 and the fixed body 21 are of a split structure, so that the locking member 23 can be made of a metal material with greater strength, and the fixed body 21 can be made of a plastic material with lower cost. The accommodating cavity is through-through front and back for the connecting member 3 to pass through. The connecting member 3 is inserted into the accommodating cavity and plugged into the plug hole 231 on the locking member 23, and the connecting member 3 and the positioning member 22 are rotated in conjunction with each other. The limiting structure is a matching structure arranged on the positioning member 22 and the inner wall of the accommodating cavity. The connecting member 3 can rotate between the locking position and the unlocking position relative to the fixed body 21 or the locking member 23, and the positioning member 22 can rotate between the first position and the second position relative to the fixed body 21. When the connecting member 3 rotates between the locking position and the unlocking position, it drives the positioning member 22 to rotate relative to the fixed body 21 between the first position and the second position. When the positioning member 22 rotates to the first position and the second position, the rotation positioning is achieved through the limiting structure, thereby achieving rotation positioning when the connecting member 3 rotates to the locking position and the unlocking position through the cooperation between the positioning member 22 and the fixed body 21.

[0046] See also Figures 7 to 11In this embodiment, the fixed body 21 includes a front body 211 and a rear cover body 212 which is snap-fitted and installed at the rear end of the front body 211. The front body 211 is provided with a first groove portion (not marked in the figure) which is open at the rear end and matches the shape of the locking member 23. The rear cover body 212 is provided with a second groove portion 2121 which is open at the front end and matches the shape of the positioning member 22. The first groove portion of the front body 211 and the second groove portion 2121 of the rear cover body 212 are arranged front and rear oppositely to form the accommodating cavity. The locking member 23 is embedded in the first groove portion of the front body 211 and cannot rotate relative to the front body 211. The positioning member 22 is rotatably embedded in the second groove portion 2121 of the rear cover body 212. An insertion hole 2111 for inserting the connecting member 3 into the accommodating cavity is provided at the front end of the front body 211 corresponding to the plug-in hole 231 on the locking member 23. An exit hole 2122 for extending the connecting member 3 out of the accommodating cavity is provided at the rear end of the rear cover body 212. Please refer to Figure 4 , Figure 5 and Fig.10 The fixed body 21 is fixedly installed on the rear side of the fixed frame 1. The fixed frame 1 is provided with a second through hole 11 for the connector 3 to movably pass through, corresponding to the insertion hole 2111 on the front body 211. The second through hole 11, the insertion hole 2111, the plug hole 231 and the outlet hole 2122 are all coaxially arranged.

[0047] See also Figure 8 , Figures 10 to 14 In this embodiment, the positioning member 22 is provided with a first through hole 221 coaxially arranged with the plug hole 231, and the connecting member 3 is movably inserted into the first through hole 221. The shape of the first through hole 221 is adapted to the outer contour of the connecting member 3, so that when the connecting member 3 rotates relative to the fixed body 21 between the locking position and the unlocking position, it can drive the positioning member 22 to rotate synchronously, thereby realizing the rotation linkage cooperation between the connecting member 3 and the positioning member 22.

[0048] See also Figures 7 to 9In this embodiment, the limiting structure includes a first positioning portion 2123, a second positioning portion 2124 and a limiting groove 2125 provided on the inner wall of the accommodating cavity, and an elastic portion 222 and a limiting protrusion 223 provided on the positioning member 22. When the positioning member 22 rotates to the first position, the elastic portion 222 and the first positioning portion 2123 are engaged and matched to realize the rotational positioning of the positioning member 22, thereby realizing the rotational positioning of the connecting member 3 when it is in the locked position. When the positioning member 22 rotates to the second position, the elastic portion 222 and the second positioning portion 2124 are engaged and matched to realize the rotational positioning of the positioning member 22, thereby realizing the rotational positioning of the connecting member 3 when it is in the unlocked position. The limiting protrusion 223 is located in the limiting groove 2125 and is limitedly matched with the limiting groove 2125 to limit the rotational amplitude of the positioning member 22, thereby limiting the rotation of the positioning member 22 between the first position and the second position, thereby limiting the rotation of the connecting member 3 between the locked position and the unlocked position. Specifically, the elastic portion 222 and the limiting protrusion 223 are both arranged on the circumferential side wall of the positioning member 22. Correspondingly, the first positioning portion 2123, the second positioning portion 2124 and the limiting groove 2125 are all opened on the inner wall of the second groove portion 2121 of the rear cover body 212. The limiting groove 2125 is an arc groove extending circumferentially along the inner wall of the second groove portion 2121. During the rotation of the positioning member 22 between the first position and the second position, the limiting protrusion 223 slides along the arc groove.

[0049] See also Figures 7 to 9 In this embodiment, the positioning member 22 is a circular positioning piece, the elastic portion 222 and the limiting protrusion 223 are both formed by the circumferential side wall protrusion of the positioning piece, the first positioning portion 2123 and the second positioning portion 2124 are grooves opened on the inner wall of the accommodating cavity, and an elastic yielding hole 224 is provided at the position of the positioning piece corresponding to the elastic portion 222. When the elastic portion 222 is squeezed by the inner wall of the accommodating cavity, a certain elastic deformation is generated, and the elastic yielding hole 224 yields to the elastic portion 222. Specifically, the positioning piece is made of plastic, and the elastic part 222 and the limiting protrusion 223 are distributed at the radial ends of the positioning piece. The elastic part 222 is arc-shaped, so that when the positioning piece rotates between the first position and the second position, the elastic part 222 can be smoothly inserted into or disengaged from the first positioning part 2123 or the second positioning part 2124. The elastic yield hole 224 is an arc-shaped through hole, and the length of the arc-shaped through hole extends along the circumference of the positioning piece. The two side walls of the limiting protrusion 223 are set as straight surfaces that can cooperate with the side walls of the two end ends of the limiting groove 2125.

[0050] See also Figures 7 to 9In this embodiment, a clearance space 2126 is provided on the inner wall of the accommodating cavity at a position between the first positioning portion 2123 and the second positioning portion 2124 corresponding to the elastic portion 222, so as to make way for the elastic portion 222 when the positioning member 22 rotates between the first position and the second position. Arc-shaped protrusions 2127 are formed between the two ends of the clearance space 2126 and the first positioning portion 2123 and the second positioning portion 2124, respectively. The arc-shaped protrusion 2127 is formed by protruding from the inner side wall of the accommodating cavity. The provision of the clearance space 2126 can reduce the resistance encountered by the positioning member 22 during the rotation between the first position and the second position, prevent the elastic portion 222 from being squeezed and deformed excessively and failing, and extend the service life of the positioning member 22. When the positioning member 22 rotates from the first position to the second position, the elastic portion 222 disengages from the first positioning portion 2123 and is pressed by the arc-shaped protrusion 2127 between the first positioning portion 2123 and the clearance space 2126, causing a certain deformation. As the positioning member 22 rotates, the elastic portion 222 moves to the position of the clearance space 2126 and is reset, and slides along the clearance space 2126. When the elastic portion 222 moves to the position between the clearance space 2126 and the second positioning portion 2124, it is pressed by another arc-shaped protrusion 2127 and is reset. As the positioning member 22 rotates, the elastic portion 222 is snapped into the second positioning portion 2124 and is reset. Similarly, when the positioning member 22 rotates from the second position to the first position, the movement process of the elastic portion 222 is exactly the opposite of the above process, which will not be repeated here.

[0051] In this embodiment, the fixing frame 1 is pre-buried in the wall, one end of the connecting member 3 is connected to the locking unit 2, and the other end of the connecting member 3 extends outside the wall to be connected to the member to be fixed.

[0052] The present invention further provides a bathroom equipment, comprising any of the above-mentioned fast-adjustable fixing devices and a part to be fixed, wherein the part to be fixed is a bathroom body, and the bathroom body is fixed to the fixing frame 1 through a connecting member 3. In this embodiment, the bathroom body is a toilet body, a washbasin, a bathroom cabinet, a mop pool, etc.

[0053] The working principle of the present invention is briefly described as follows:

[0054] In the process of inserting the connecting member 3 into the accommodating cavity of the fixing body 21, as shown in FIG. Fig. 9 As shown, in the initial state, the positioning member 22 is located at the second position, the elastic portion 222 is engaged with the second positioning portion 2124, and a side wall of the limiting protrusion 223 is in contact with a side wall of one end of the limiting groove 2125. Fig.10As shown, align one end of the connecting member 3 with the second through hole 11 on the fixing frame 1, so that the second engaging portion 31 on the connecting member 3 is opposite to the first giving way portion 233 on the inner wall of the plug hole 231, and the second giving way portion 32 on the connecting member 3 is opposite to the first engaging portion 232 on the inner wall of the plug hole 231;

[0055] like Fig.11 As shown, one end of the connecting member 3 is sequentially passed through the second through hole 11 on the fixing frame 1, the insertion hole 2111 on the fixing body 21, the plugging hole 231 on the locking member 23, the first through hole 221 on the positioning member 22 and the through hole 2122 on the fixing body 21. During this process, the first yielding portion 233 yields to the second meshing portion 31, and the second yielding portion 32 yields to the first meshing portion 232. The connecting member 3 is in the unlocked position, that is, the connecting member 3 and the locking unit 2 are in the unlocked state, so that the connecting member 3 can be axially extended and retracted relative to the fixing body 21 to quickly adjust the length of the connecting member 3 exposed from the fixing frame 1. Fig.12 : shows a schematic diagram of the cooperation between the connecting member 3, the locking member 23, the positioning member 22 and the rear cover 212 when the connecting member 3 and the locking unit 2 are in the unlocked state;

[0056] When the connector 3 is inserted into place, Figure 13 to Figure 14 As shown, the connecting member 3 is rotated from the unlocking position to the locking position relative to the locking member 23, and the positioning member 22 is rotated from the second position to the first position along with the connecting member 3, and the first meshing portion 232 is meshed with the second meshing portion 31 to lock the connecting member 3, and the other side wall of the limiting protrusion 223 is abutted against the side wall of the other end of the limiting groove 2125 to limit the rotation angle of the positioning member 22, and at the same time, the elastic portion 222 and the first positioning portion 2123 are engaged with each other to prevent the positioning member 22 from rotating to a certain extent, thereby realizing the rotation positioning of the positioning member 22 in the first position, and the other end of the connecting member 3 extends to the outside of the wall and is connected to the bathroom body;

[0057] When it is necessary to adjust the extension length of the connecting member 3 relative to the fixed body 21, the connecting member 3 is rotated in the opposite direction from the locked position to the unlocked position, and the positioning member 22 is rotated from the first position to the second position along with the connecting member 3. At this time, the extension length of the connecting member 3 can be quickly adjusted. After the extension length of the connecting member 3 is adjusted to the specified position, the connecting member 3 can be rotated from the unlocked position to the locked position to lock the connecting member 3 again.

[0058] In other embodiments, the limiting groove is formed on the positioning member, the limiting protrusion is disposed on the inner wall of the accommodating cavity, and the limiting groove is an arc-shaped groove extending along the circumference of the positioning member.

[0059] In other embodiments, the first meshing portion and the second meshing portion are meshable teeth, the first meshing portion has a plurality of teeth spaced apart along the axial direction of the plug hole, and the second meshing portion has a plurality of teeth spaced apart along the axial direction of the connector.

[0060] In other embodiments, the locking member is fixed in the accommodating cavity, the locking member and the fixing body are an integrated structure, and the accommodating cavity is through-connected front to back for the connecting member to pass through.

[0061] In other embodiments, the locking member is directly fixedly mounted on the fixing frame.

[0062] In other embodiments, the connecting member 3 is only rotated and positioned relative to the fixing frame 1 by the positioning member 22 when the connecting member 3 is in the locked position or the unlocked position. When the connecting member 3 is rotated and positioned relative to the fixing frame 1 in the locked position, the positioning member is rotated to the first position and rotated and positioned by the limiting structure, so that the installation process of the part to be fixed is simple and easy; and when the connecting member 3 is rotated and positioned relative to the fixing frame 1 in the unlocked position, the positioning member is rotated to the second position and rotated and positioned by the limiting structure, so that the removal process of the part to be fixed is simple and easy. Of course, it is preferred to adopt the above embodiment and select the connecting member 3 to be rotated and positioned relative to the fixing frame 1 by the positioning member 22 in both the locked position and the unlocked position, so that the installation and removal processes of the part to be fixed are simple, easy, convenient, and have better effects.

[0063] The above embodiments are only used to further illustrate a quick-adjustable fixing device and bathroom equipment having the same of the present invention, but the present invention is not limited to the embodiments. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention fall within the protection scope of the technical solution of the present invention.
