[0003] Taking the installation of the ceramic body of a wall-mounted toilet on the wall as an example, first install the lock as a whole to the rear end of the ceramic body, then align the screw hole of the driven gear with the screw preset on the wall, and then use a tool to penetrate the ceramic body and turn the driving gear. The linkage is achieved through the meshing relationship between the driving gear and the driven gear, and the driven gear is turned toward the wall. Finally, the lock cooperates with the wall to clamp the rear end of the ceramic body, thereby locking the ceramic body to the wall.

DETAILED DESCRIPTION

[0042] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0043] refer to Figures 1 to 21 As shown, the present invention discloses a locking structure for a wall-mounted toilet, comprising a locking device body 1, a driving gear 2, a driven gear 3 and a movable locking member 4; The driving gear 2 and the driven gear 3 are both rotatably engaged in the locking body 1 and mesh with each other to achieve transmission from the driving gear 2 to the driven gear 3. The surface of the locking body 1 is respectively provided with a first through-hole 111 and a second through-hole 121 which are respectively arranged opposite to the driving gear 2 and the driven gear 3. A first passage 31 is provided between both end surfaces of the driven gear 3 , and the movable locking member 4 is movably fitted in the first passage 31 ; A second channel 41 and a third channel 42 are provided between the two end surfaces of the movable locking member 4 and cross-overlapping with each other (see Figure 3 or Figure 11The second channel 41 and the third channel 42 can both be passed through by screw rod a, which is pre-fixed to the wall. Both second channel 41 and third channel 42 are opposite second through-hole 121. The inner wall of the end of second channel 41 near second through-hole 121 is provided with a plurality of screw threads 411, which do not overlap with third channel 42. The size, shape, and other features of screw threads 411 are designed to match the shape of screw rod a. However, any overlap between screw threads 411 and third channel 42 is eliminated, thereby achieving "non-overlap."

[0044] Through the above scheme, the present invention provides a swingable movable locking member 4 in the driven gear 3, and the movable locking member 4 has a second channel 41 and a third channel 42 that can be passed through by the screw a, and the inner wall of the second channel 41 is provided with a screw thread 411. When the screw a penetrates the second through-hole 121 of the locker body 1 and penetrates the movable locking member 4, it can push the movable locking member 4 to swing it, so that the third channel 42 is coaxial with the screw a. The screw a can quickly pass through the movable locking member 4, so that the ceramic body installed with the present invention can be quickly approached to the installation surface (referring to the wall or the wall-mounted bracket). In this process, there is no need to use a tool to twist the driving gear 2, and When the ceramic body is moved into position, the movable locking member 4 can be reset. At this time, the second channel 41 is coaxial with the screw rod a, and the screw thread 411 is engaged with the screw rod a, so that the locking structure realizes self-tightening. After applying the present invention, when installing the ceramic body, it is only necessary to roughly measure the length of the screw rod a exposed from the mounting surface, and then the ceramic body can be directly installed until it abuts the mounting surface, and then a tool is used to penetrate the first through-hole 111 to twist the driving gear 2 for locking. At the same time, after the ceramic body abuts the mounting surface, the locking structure is self-tightened and the ceramic body is directly hung on the screw rod a. No additional support is required, and the installer can perform the locking action calmly, thereby reducing the installation difficulty and labor cost.

[0045] refer to Figures 1 to 8 FIG. 1 shows a first embodiment of the present invention.

[0046] A clearance recess 311 is provided on one side of the first channel 31 to provide clearance space when the movable locking member 4 swings and to ensure that the movable locking member 4 can only swing in that direction after the screw a penetrates the movable locking member 4; the clearance recess 311 and the screw thread 411 are located on the same side. When installing the ceramic body, the driving gear 2 can be rotated to engage the driven gear 3, and the clearance recess 311 can be pre-positioned upward. This allows the movable locking member 4 to swing up and down when the ceramic body is inserted into the screw a. When the ceramic body is moved into place, the movable locking member 4 can rely on self-reset.

[0047] The above-mentioned movable locking member 4 is swingably connected to the side wall of the first channel 31, and a swing shaft 43 is provided on both sides of the movable locking member 4; the swing shaft 43 rotates with the inner wall of the first channel 31, and the central axis of the swing shaft 43 is perpendicular to the central axis of the second channel 41 and the third channel 42.

[0048] Furthermore, the central axes of the second channel 41 , the third channel 42 and the swing shaft 43 intersect at the same point.

[0049] The locker body 1 includes a detachably connected cover 11 and a housing 12. The first through-hole 111 and the second through-hole 121 are formed in the cover 11 and the housing 12, respectively. The upper surface of the housing 12 is recessed to form a first movable cavity 122 and a second movable cavity 123. The second through-hole 121 is connected to the second movable cavity 123. The driving gear 2 and the driven gear 3 are rotatably engaged in the first movable cavity 122 and the second movable cavity 123, respectively. The cover 11 covers the upper surface of the housing 12.

[0050] The driving gear 2 is provided with a groove 21 opposite to the first through hole 111 . The groove 21 matches the shape of the tool, for example, it can be a hexagonal groove to match an external hexagonal wrench.

[0051] The present invention further includes an adjusting cylinder 5 . The second through hole 121 of the locking device body 1 extends outwardly along the axial direction to form a sleeve 124 . The adjusting cylinder 5 is passed through the sleeve 124 and is threadedly connected to the sleeve 124 .

[0052] Furthermore, the adjusting cylinder 5 has a radially extending retaining ring 51 on its circumference at the end away from the locking body 1. By replacing the adjusting cylinder 5 with retaining rings 51 of varying thicknesses and fine-tuning the depth of engagement between the adjusting cylinder 5 and the locking body 1, ceramic bodies of varying thicknesses can be adapted for locking.

[0053] refer to Figures 5 to 8 As shown, the working principle of the first embodiment is: ① The movable locking member 4 is swingably engaged in the driven gear 3 by means of the swing shafts 43 on both sides thereof; ② Before installing the locker as a whole to the ceramic body, it is best to use a tool to first turn the driving gear 2 to link the driven gear 3, so that the movable locking member 4 rotates synchronously and its swing axis 43 is in a horizontal state, and the screw thread 411 is located in the upper position (see Figure 4 state), so that after subsequent locking, the self-weight of the movable locking member 4 can be used to achieve the purpose of self-locking; ③ During the installation of the ceramic body, the entire locker is first installed on the rear end of the ceramic body; after the screw a pre-embedded in the installation surface (i.e., the wall or wall-mounted bracket) penetrates the second through-hole 121 of the locker body 1 and penetrates the movable locking member 4, the movable locking member 4 can be pushed against to swing it until the third channel 42 is coaxial with the screw a. At this time, the screw a can quickly pass through the movable locking member 4, allowing the ceramic body of the present invention to be quickly approached to the installation surface. During this process, no tools are required to turn the driving gear 2. ④ When the ceramic body is moved into position, the movable locking part 4 relies on self-repositioning. At this time, the second channel 41 is coaxial with the screw a, and the screw thread 411 is engaged with the screw a. The locking structure is self-tightening and pre-fixed so that the ceramic body can be directly hung on the screw a. No additional support is required and no axial movement will occur. The installer can perform the locking action calmly, thereby reducing the installation difficulty and labor cost.

[0054] refer to Figures 9 to 21 FIG. 2 shows a second embodiment of the present invention.

[0055] The main difference between the second embodiment and the first embodiment lies in the matching method between the driven gear 3 and the movable locking member 4. Apart from this, the relevant structural designs of the second embodiment not mentioned below can all adopt the technical means of the first embodiment, or adopt equivalent replacement technical means.

[0056] A recessed portion 311 is provided on one side of the first passage 31 to provide a clearance space when the movable locking member 4 swings, and to ensure that the movable locking member 4 can only swing in this direction after the screw a penetrates the movable locking member 4.

[0057] During installation, the first channel 31 is provided with two first limiting shafts 32 and 32' on the inner wall of the end away from the screw a, and the two first limiting shafts 32 and 32' are located at the same diameter ends of the driven gear 3 at that end. The movable locking member 4 is provided with a first movable groove 44 on its circumferential surface, which is opposite to the first limiting shaft 32. One end of the first movable groove 44 is connected to the same-direction end surface of the movable locking member 4 to enable the first limiting shaft 32 to enter the first movable groove 44. The other end of the first movable groove 44 is provided with a guide bevel 441. Therefore, during installation, no matter what position or state the movable locking member 4 is in the locker, no adjustment is required. The screw a can be directly inserted and the guide bevel 441 automatically adjusts the movable locking member 4 to the installation position during installation.

[0058] refer to Figure 13 、 14 As shown, for the structure of the above paragraph, specifically: ① After the screw a is inserted, the thrust generated by the contact between the screw thread 411 and the screw a causes the movable locking member 4 and the driven gear 3 to move relative to each other. The movable locking member 4 moves axially in the first channel 31, and the first limiting shaft 32 moves in the first movable groove 44 until it abuts the guide inclined surface 441. ② At this time, since the driving gear 2 is not rotating and the driven gear 3 (i.e., the first channel 31) is in a relatively fixed state, the first limiting shaft 32 continues to abut against the guide inclined surface 441, causing the movable locking member 4 to rotate. Finally, the first limiting shaft 32 abuts against the side wall of the first movable groove 44 connected to the distal end of the guide inclined surface 441 and stops moving. The movable locking member 4 and the first limiting shaft 32 are relatively fixed. ③ After the screw a continues to be inserted, the movable locking member 4 will swing with the first limiting shaft 32 on both sides, performing the same action as the first embodiment, that is, when the screw a is inserted, the third channel 42 is coaxial with the screw a, and the screw a is quickly inserted.

[0059] Furthermore, a first limiting rib 442 is provided at the end of the first movable groove 44 that connects to the end surface of the movable locking member 4. An opening is left between the first limiting rib 442 and the side wall of the first movable groove 44 for the first limiting shaft 32 to enter and exit. Thus, when tightening the driving gear 2, the first limiting shaft 32 will abut against the side wall of the first movable groove 44 connected to the proximal end of the guide slope 441, driving the movable locking member 4 to rotate; and when loosening the driving gear 2, the first limiting shaft 32 will abut against the end wall of the first limiting rib 442, driving the movable locking member 4 to rotate in the opposite direction.

[0060] Secondly, the first channel 31 is also provided with a second limiting shaft 33 on the inner wall of the end away from the screw a during installation; the circumferential surface of the movable locking member 4 is provided with a second movable groove 45 opposite to the first limiting shaft 32; the end of the second movable groove 45 in the same direction is provided with a second limiting rib 451, and an opening for the second limiting shaft 33 to enter and exit is reserved between the second limiting rib 451 and the side wall of the second movable groove 45; the state of the first limiting shaft 32 in the first movable groove 44 is synchronized with the state of the second limiting shaft 33 in the second movable groove 45. Therefore, when the screw a is pulled out, the second limiting shaft 33 will abut against the inner wall of the second limiting rib 451, and the movable locking member 4 will swing with the second limiting shaft 33 (see Figure 21 ), during the process of pulling out the screw a, the third channel 42 can also be made coaxial with the screw a so as to quickly pull out the screw a.

[0061] At the same time, the inner wall of the end of the first channel 31 near the screw a during installation is provided with an arcuate groove 34. The circumferential surface of the end of the movable locking member 4 in the same direction is provided with a stop block 46 that fits flexibly within the arcuate groove 34. The cooperation between the stop block 46 and the arcuate groove 34 can limit the relative rotation angle between the movable locking member 4 and the driven gear 3, thereby making the movement of the movable locking member 4 more accurate.

[0062] refer to Figures 15 to 17 As shown, the installation process of the second embodiment is as follows: When the driving gear 2 rotates forward, it drives the driven gear 3 to rotate, and then drives the movable locking member 4 to rotate, locking it to the screw a; specifically, the first limiting shaft 32 of the driven gear 3 abuts against the side wall of the first movable groove 44 connected to the proximal end of the guide bevel 441, driving the movable locking member 4 to rotate; the rotation of the movable locking member 4 causes the screw tooth 441 to engage with the thread of the screw a, tightening and fixing it.

[0063] refer to Figures 18 to 21 As shown, the disassembly process of the second embodiment is as follows: When the driving gear 2 rotates in the opposite direction, it drives the driven gear 3 to rotate, and then drives the movable locking piece 4 to rotate, unlocking it from the screw a; specifically, the first limiting shaft 32 of the driven gear 3 abuts against the side wall of the first movable groove 44 connected to the distal end of the guide bevel 441, driving the movable locking piece 4 to rotate; under the action of the thread of the screw a, the movable locking piece 4 rotates and retreats until the second limiting shaft 33 abuts against the inner wall of the second limiting rib 451; thereafter, the movable locking piece 4 will swing upward with the second limiting shaft 33 as the fulcrum, and the third channel 42 is coaxial with the screw a, so that the screw a can be quickly pulled out of the movable locking piece 4 to achieve quick release.

[0064] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
