Description

Technical Field

[0001] This utility model relates to an installation structure for a toilet seat. Background Technology

[0002] The toilet seat and ceramic body (or ceramic toilet bowl) are usually connected by a bracket. The bracket is locked to the ceramic body, and the support post of the bracket can be inserted into the toilet seat. Therefore, the ceramic body needs to have mounting holes on its upper surface for installing the bracket. This creates hard-to-clean areas on the upper surface of the ceramic body. Moreover, in order to securely connect with the ceramic body, the base of the bracket needs to be relatively thick to accommodate the head of the locking bolt. After the toilet seat is assembled, there is a large gap between the bracket and the ceramic body, resulting in poor toilet integrity. Utility Model Content

[0023] Example 1:

[0024] Please refer to Figures 1 to 3The toilet seat mounting structure includes a connecting arm 10 and a bolt assembly 20. The connecting arm 10 is detachably connected to the toilet ceramic body 30 via the bolt assembly 20. The connecting arm 10 is located at the rear of the outer side of the toilet ceramic body 30 (defined as the direction against the wall). The lower end of the connecting arm 10 is connected to the bolt assembly 20. The connecting arm 10 extends vertically upward toward the upper surface of the toilet ceramic body 30 and also includes a connector 40. The lower end of the connector 40 is connected to the connecting arm 10, and the upper end of the connector 40 is inserted into the toilet seat 50. The bolt assembly 20 is located on the side of the toilet ceramic body 30, does not occupy the space on the top surface of the toilet ceramic body 30, does not affect the tightness of the fit between the toilet seat 50 and the toilet ceramic body 30, and at the same time makes the upper surface of the toilet ceramic body 30 flat.

[0025] Preferably, the connector 40 has an L-shaped structure, with its vertical portion plugging into the connecting arm 10 and its horizontal portion plugging into the toilet seat 50. Therefore, when the toilet seat 50 needs to be removed, the connector 40 is attached to the toilet seat 50 and can be removed together with the toilet seat 50, making the installation and removal of the toilet seat 50 very convenient.

[0026] Preferably, the connector 40 is fitted with an elastic retaining ring 42 at the part where it is inserted into the connecting arm 10, and the elastic retaining ring is clamped between the connector and the connecting arm.

[0027] Preferably, an anti-detachment buckle 44 is provided between the lateral portion of the connector 40 and the toilet seat 50 to prevent the connector 40 from separating laterally from the toilet seat 50.

[0028] Preferably, the bolt assembly 20 is laterally pressed and fixed to the connecting arm 10, that is, the bolt assembly 20 locks the connecting arm in the lateral direction, that is, in the left-right direction. The bolt assembly 20, the connecting arm 10 and the plug 40 are configured to connect the toilet seat and the toilet ceramic body.

[0029] Preferably, the bolt assembly 20 includes a locking bolt 21, a locking guide tube 22, and a plug 23. The inner side of the bottom of the connecting arm 10 is provided with a connector 11 with a shoulder. The side of the toilet ceramic body 30 is provided with an assembly hole 32. The connector 11 is inserted into the assembly hole 32. The plug 23 is fitted onto the connector 11 and clamped between the connector 11 and the assembly hole 32. The inner end of the locking guide tube 22 is connected to a locking device 34 disposed within the toilet ceramic body 30 for wall mounting. The outer end of the locking guide tube 22 is inserted into the connector 11. The locking bolt 21 passes through the connector 11 and is threadedly connected to the locking guide tube 22. Specifically, the locking guide tube 22 and the locking device 34 are locked together with screws. Thus, the connecting arm 10 can be locked to the side of the toilet ceramic body 30 using the locking bolt 21.

[0030] Preferably, the structure consisting of a spline groove and a spline between the connector 11 and the locking guide tube 22 achieves radial anti-rotation, thereby keeping the connecting arm 10 vertically positioned and making the structure more stable.

[0031] Example 2:

[0032] Please refer to Figures 4 to 6 The difference between Embodiment 2 and Embodiment 1 lies in three aspects: first, the structure of the connecting arm; second, the structure of the plug-in component; and third, the structure of the bolt assembly. Specifically, the upper end of the connecting arm 10a bends inward to form a snap-edge 13 that hangs on the upper surface of the toilet ceramic body 30. The plug-in component 40a is a vertically arranged pin structure connected to the snap-edge 13. The bolt assembly 20a and the connecting arm 10a are constructed to connect to the side of the toilet ceramic body 30 in a [shape].

[0033] Preferably, the bolt assembly 20a includes an expansion bolt unit and a set screw 24. The toilet ceramic body has an assembly hole on its side. The expansion bolt unit is installed and fixed in the assembly hole 32 on the side of the toilet ceramic body. The set screw 24 can detachably tighten and fix the connecting arm 10a and the expansion bolt unit together.

[0034] More preferably, the expansion bolt unit includes a locking bolt 25, an expansion tube 26, and a plug 27. The expansion tube 26 passes through the mounting hole 32, and the plug 27 is fitted onto the expansion tube 26 and positioned between the expansion tube 26 and the mounting hole 32. The locking bolt 25 is screwed to the expansion tube 26. During the tightening of the locking bolt 25, the expansion tube 26 expands outward and presses the plug 27 into the mounting hole 32. In other words, the expansion bolt unit expands and fixes itself to the mounting hole 32 of the toilet ceramic body 30 during installation, and then the connecting arm 10a is locked to the expansion bolt unit by the set screw 24.

[0035] More preferably, the set screw 24 is threadedly connected to the connecting arm 10a. The set screw 24 is screwed vertically into the connecting arm 10a from the bottom upwards. The set screw 24 and the locking bolt 25 have matching guide bevels. During the tightening of the set screw 24, the connecting arm 10a simultaneously presses against the side of the toilet ceramic body 30 and presses against the upper surface of the toilet ceramic body 30 from the bottom downwards. That is, after the set screw 24 is screwed in, the reaction force of the locking bolt 25 on the set screw 24 is divided into two parts under the action of the guide bevels. One part, a lateral inward force, causes the connecting arm 10a to press against the toilet ceramic body 30 from the bottom. The other part, a vertical downward force, causes the retaining edge 13 of the connecting arm 10a to press against the upper surface of the toilet ceramic body 30.

[0036] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model patent and the contents of the specification should still fall within the scope of the present utility model.
