[0003] When installing a wall-mounted toilet, the water tank and drain pipe need to be placed inside the wall. There is only a section of the toilet body on the wall without the water tank, which makes the space utilization rate of the bathroom greater. Moreover, the wall-mounted toilet is hung on the surface of the wall, a certain distance from the ground, which saves time and effort when cleaning the bathroom. The most important thing is that the existence of the wall can well isolate the noise of flushing, which has a good noise reduction effect. Due to the characteristics of fashionable appearance, space saving, easy cleaning, and noise reduction, wall-mounted toilets have gradually become popular in China in recent years and are widely used in high-end real estate.

[0004] When installing the existing wall-mounted toilet, the toilet is mainly fastened by a locking device; however, before the locking device is locked, one person needs to hold the toilet while another person locks the toilet, which makes it impossible for one person to install it, and the installation is inconvenient.

[0047] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0048] A fixing device of the present invention is used to fix a first component 10 and a second component 20 in connection, the fixing device comprising a connector 30 connected to the first component 10 and a base 40 connected to the second component 20, the connector 30 and the base 40 being locked and connected via a locking mechanism 50; the fixing device also comprises a pre-locking mechanism having a pre-locking state and an unlocking state, before the locking mechanism locks the connector 30 and the base 40, the pre-locking mechanism is in the pre-locking state, the connector 30 and the base 40 are limitedly matched by the pre-locking mechanism to prevent the connector 30 from being separated from the base 40, and when the pre-locking mechanism is in the unlocking state, the connector 30 can be separated from the base 40.

[0049] First embodiment (the screw connection member comprises a screw connection portion and an abutment member, the screw connection portion is a screw sleeve, the abutment member is a spring pin, and the abutment member is arranged on the screw sleeve)

[0050] like Figures 1 to 6 As shown, in this embodiment, the locking mechanism 50 includes a screw connection, and the screw connection includes a screw connection portion 56 and an abutment member 51. The screw connection portion 56 adopts a screw sleeve, and the abutment member 51 adopts a spring pin. The spring pin is movably arranged on the screw sleeve, and the locking mechanism 50 is arranged on the base 40.

[0051] The pre-locking mechanism includes a pre-locking mating surface 311 provided on the connecting member 30 and a pre-locking portion 54 provided on the locking mechanism 50. The pre-locking mating surface 311 and / or the pre-locking portion 54 can move between an unlocking position and a pre-locking position.

[0052] When the pre-locking mechanism is in the pre-locking state, the pre-locking mating surface 311 and / or the pre-locking portion 54 are in the pre-locking position, and the pre-locking mating surface 311 and the pre-locking portion 54 are limitedly matched, thereby making the connecting member 30 and the base 40 limitedly matched; when the pre-locking mechanism is in the unlocking state, the pre-locking mating surface 311 and / or the pre-locking portion 54 are in the unlocking position, and the pre-locking mating surface 311 is separated from the pre-locking portion 54, thereby making the connecting member 30 able to be detached from the base 40.

[0053] like Figure 1 and Figure 2As shown, the connecting member 30 is provided with a locking fitting surface 312, and the locking mechanism 50 locks and connects the connecting member 30 with the base 40 by locking and fitting with the locking fitting surface 312; in this embodiment, the connecting member 30 is a connecting rod, and the base 40 is provided with a connecting channel 41 for inserting the connecting rod, and the side wall of the connecting channel 41 is provided with a radial through hole 42 connected to the connecting channel 41, and the locking mechanism 50 is inserted into the connecting channel 41 through the radial through hole 42; the side wall of the connecting member 30 is provided with a lower recess 31, and the surface of the lower recess 31 forms the locking fitting surface 312.

[0054] like Figure 1 As shown, in this embodiment, the pre-locking mating surface 311 is arranged on the end side wall of the lower recess 31, and the locking mating surface 312 is arranged in the middle of the lower recess 31. Preferably, the pre-locking mating surface 311 is a first straight surface, the pre-locking portion 54 is a second straight surface, and the locking mating surface 312 is an arc-shaped concave surface. Optionally, the locking mating surface 312 can also be a straight surface.

[0055] like Figure 2 As shown, the screw connection is threadedly connected to the radial through hole 42, and when the screw connection is rotated, the screw connection is locked and matched with the locking matching surface 312. In this embodiment, the screw connection includes a screw connection portion 56 and an abutment 51 movably arranged on the screw connection portion 56, and the pre-locking portion 54 is arranged on the abutment 51. In the pre-locking state, the pre-locking portion 54 on the abutment 51 is limitedly matched with the pre-locking matching surface 311. When the screw connection portion 56 is rotated, the screw connection portion 56 drives the abutment 51 so that the abutment 51 is locked and matched with the locking matching surface 312.

[0056] The abutment member 51 is a spring pin or a swing block, and the threaded connection portion 56 is a threaded sleeve or a screw. In this embodiment, the abutment member 51 is a spring pin, and the threaded connection portion 56 is a threaded sleeve, and the spring pin is sleeved in the threaded sleeve.

[0057] Specifically, the elastic pin includes a latch 511 and a spring 512. One end of the latch 511 extends out of the threaded portion 56 under the action of the spring 512 and extends into the connecting channel 41 to be limitedly matched with the pre-locking matching surface 311 or locked with the locking matching surface 312. The side wall of the end of the latch 511 extending into the connecting channel 41 forms the pre-locking portion 54. The latch 511 is provided with a first limiting portion 52, and the threaded portion 56 is provided with a limiting step 561 for limiting the first limiting portion 52. The first limiting portion 52 and the limiting step 561 cooperate to prevent the latch 511 from escaping from the threaded portion 56 under the action of the spring 512. The elastic pin also includes a positioning screw 55 threadedly connected to the latch 511. The end surface of the positioning screw 55 forms the first limiting portion 52. The end surface of the positioning screw 55 is limitedly matched with the limiting step 561 on the threaded portion 56. The latch pin 511 is also provided with a second limiting portion 53, and the inner end surface of the threaded portion 56 abuts against the second limiting portion 53. The threaded portion 56 drives the latch pin 511 to move along the locking mating surface 312 through the abutment with the second limiting portion 53 to lock the connecting member 30 and the base 40.

[0058] In this embodiment, the disassembly and assembly process of the fixing device is briefly described as follows, taking the first component as a wall and the second component as a toilet body as an example:

[0059] First, the connecting member 30 is fixedly connected to the wall, and the base 40 is fixed on the toilet body 20;

[0060] like Figure 2 As shown, in the initial state, the spring pin (abutment member 51) is movably mounted in the screw sleeve (screw connection portion 56) and partially extends out of the screw sleeve. The screw sleeve equipped with the spring pin is screwed into the radial through hole 42 of the base 40, so that one end of the spring pin extends into the connecting channel 41. The toilet body 20 is moved along the direction of the wall 10, so that the base 40 is plugged and matched with the connecting member 30 in the axial direction, so that the connecting member 30 is inserted into the connecting channel 41 of the base 40 in the axial direction relative to the base 40. At this time, the pre-locking portion 54 on the latch 511 is not limitedly matched with the pre-locking matching surface 311 on the connecting member 30.

[0061] like Figure 3 and Figure 4As shown, the toilet body 20 continues to be moved toward the wall 10, so that the connecting member 30 continues to be inserted axially into the connecting channel 41 of the base 40, until the connecting member 30 squeezes the spring pin (abutment member 51) to deform the spring pin, thereby allowing the pre-locking portion 54 to pass over the pre-locking mating surface 311 (first straight surface) of the connecting member 30 and limit the pre-locking mating surface 311, so that the base 40 will not be separated from the connecting member 30, that is, the connecting member 30 will not reversely exit the connecting channel 41, thereby achieving the hooking of the toilet body by the pre-locking mechanism.

[0062] like Figure 5 and Figure 6 As shown, at this time, the toilet body is hung by the connecting piece 30, and the installation worker does not need to free up his hands to hold the toilet body. The screw sleeve (screw connection part 56) can be rotated in the forward direction, and the inner end surface of the screw sleeve drives the spring pin to move along the locking matching surface 312 (arc-shaped concave surface), so that the base 40 moves toward the wall, and then the wall and the toilet body are pressed close to each other, thereby completing the locking of the toilet body.

[0063] When disassembling the toilet body, it is only necessary to rotate the screw sleeve in the opposite direction until the pre-locking portion 54 (the second straight surface) of the spring pin exits the connecting channel 41 of the base 40 without being limitedly engaged with the pre-locking mating surface 311 (the first straight surface) of the connecting piece 30. At this time, the pre-locking mechanism is in an unlocked state, so that the connecting piece 30 can be separated from the base 40, thereby completing the disassembly of the toilet.

[0064] Second embodiment (the screw connection member is a screw, the pre-locking portion is provided at one end of the screw, a movable pin and an elastic member are provided on the connection member, and the pre-locking mating surface is formed on the movable pin)

[0065] like Figures 7 to 12 As shown, the main difference between this embodiment and the first embodiment is that: in this embodiment, a movable pin 57 and an elastic member 58 are provided on the connecting member 30, the elastic member 58 is a compression spring and is arranged between the movable pin 57 and the connecting member 30, the pre-locking matching surface 311 is formed on the movable pin 57, the threaded member is a screw 56', and the end of the screw 56' extending into the connecting channel 41 is correspondingly provided with a limiting step 561, and the limiting step 561 forms the pre-locking portion 54, the movable pin 57 can reciprocate under the action of the elastic member 58 so that the pre-locking matching surface 311 can reciprocate between the unlocking position and the pre-locking position, when the pre-locking mechanism is in the pre-locking state, the pre-locking matching surface 311 abuts against the limiting step 561 for limiting, and when the pre-locking mechanism is in the unlocking state, the pre-locking matching surface 311 is separated from the limiting step 561.

[0066] In this embodiment, the toilet is taken as an example (the first component is the wall, and the second component is the toilet body), and the disassembly and assembly process of the fixing device is briefly described as follows:

[0067] like Figure 7 and Figure 8 As shown, in the initial state, the screw 56' of the locking mechanism 50 is screwed into the radial through hole 42 of the base 40, the movable pin 57 and the elastic member 58 are assembled in the connecting member 30, and the movable pin 57 extends out of the connecting member 30 under the spring top of the elastic member 58; the toilet body 20 is moved along the direction of the wall 10, so that the base 40 is axially plug-fitted with the connecting member 30, so that the connecting member 30 is axially inserted into the connecting channel 41 of the base 40 relative to the base 40. At this time, the limiting step 561 (pre-locking portion 54) on the screw 56' is not limited and matched with the pre-locking matching surface 311 on the movable pin 57.

[0068] like Fig. 9 and Fig.10 As shown, the toilet body 20 continues to be moved toward the wall 10, so that the connecting piece 30 continues to be inserted axially into the connecting channel 41 of the base 40 until the screw 56' squeezes the movable pin 57 to deform the elastic piece 58, and the pre-locking portion 54 on the screw 56' passes over the pre-locking mating surface 311 (the first straight surface) on the movable pin 57 and is limitedly engaged with the pre-locking mating surface 311, so that the base 40 will not be separated from the connecting piece 30, that is, the connecting piece 30 will not reversely withdraw from the connecting channel 41, thereby achieving the hooking of the toilet body by the pre-locking mechanism.

[0069] like Fig.11 and Fig.12 As shown, at this time, the toilet body is hung by the connecting piece 30, and the installation worker does not need to free up his hands to hold the toilet. The screw 56' can be rotated in the positive direction, and the inner end surface of the screw 56' moves along the locking matching surface 312 (arc-shaped concave surface), so that the base 40 moves toward the wall, and then the wall and the toilet body are pressed close to each other, thereby completing the locking of the toilet body.

[0070] When disassembling the toilet, it is only necessary to rotate the screw 56' in the reverse direction until the pre-locking portion 54 (the second straight surface) of the screw 56' withdraws from the connecting channel 41 of the base 40 without being limitedly engaged with the pre-locking mating surface 311 (the first straight surface). At this time, the pre-locking mechanism is in an unlocked state, so that the connecting member 30 can be disengaged from the base 40, thereby completing the disassembly of the toilet.

[0071] The rest of the structure of this embodiment is basically similar to that of the first embodiment and will not be described in detail here.

[0072] Third embodiment (screw-joined member adopts screw, and movable pin is replaced by swing block)

[0073] The main difference between this embodiment and the second embodiment is that, in this embodiment, the movable pin 57 is replaced by a swing block (not shown), a pre-locking mating surface 311 is formed on the swing block, the swing block is swingably attached to the connecting member 30 and is limitedly mated with the limiting step 561 (pre-locking portion 54) on the screw 56' during the process of inserting the connecting member 30 into the connecting channel 41.

[0074] The rest of the structure and assembly and disassembly process of this embodiment are basically similar to those of the second embodiment and will not be described in detail here.
