[0012] The technical solution described above will be described in detail below with reference to the accompanying drawings in the description and the specific implementations, to make it better understood.
[0013] Fig. 1 is an exploded perspective view of a locking assembly, and Fig. 2 is an assembled perspective view of the locking assembly with an angle opposite that in Fig. 1.
[0014] As shown in Figs. 1 and 2, a locking assembly 10 in accordance with the present invention includes a retainer 1 and a fastener 2, the retainer 1 being provided with a sliding groove 11, the fastener 2 being formed by hinging two fastening sheets 21, 22 through a hinge shaft 3, the two fastening sheets being capable of moving in the sliding grooves 11, having a relative disengagement state and a relative engagement state, and being capable of being accommodated in the retainer 1 when in the relative engagement state, and a limiting structure for keeping the two fastening sheets at a specific disengagement angle being arranged between the two fastening sheets. The fastener 2 may be formed by hinging a first fastening sheet 21 and a second fastening sheet 22 through the hinge shaft 3, and the hinge shaft 3 may be a cylindrical nut.
[0015] The two fastening sheets are used as locking abutments, to realize a locking function when in the relative disengagement state; and the two fastening sheets may be accommodated in the retainer 1 when in the relative engagement state, to reduce an entire width of the two fastening sheets, and thus it is convenient to disassemble the retainer 1 and the fastener 2 integrally, and the locking assembly is rapidly disassembled and reusable.
[0016] As shown in Fig. 2, the first fastening sheet 21 and the second fastening sheet 22 include first hinge plates 211, 221 and second hinge plates 212, 222 which are oppositely arranged, and connecting plates 213, 223 for connecting the first hinge plates 211, 221 and the second hinge plates 212, 222, that is, the first fastening sheet 21 and the second fastening sheet 22 have the same structure, and the first fastening sheet 21 and the second fastening sheet 22 are oppositely arranged, the hinge shaft 3 being connected to the first hinge plates 211, 221 and the second hinge plates 212, 222. Parts, close to hinge ends, of the connecting plates 213, 223 of the first fastening sheet 21 and the second fastening sheet 22 are provided with cut grooves 214, 224 separately. The limiting structure which keeps the first fastening sheet 21 and the second fastening sheet 22 at the specific disengagement angle enables an end part of the hinge end of the first hinge plate 211 of the first fastening sheet 21 to be in abutting fit with a bottom of the cut groove 224 of the second fastening sheet 22, and an end part of the hinge end of the first hinge plate 221 of the second fastening sheet 22 to be in abutting fit with a bottom of the cut groove 214 of the first fastening sheet 21.
[0017] In order to install the hinge shaft 3 conveniently, the first hinge plates 211, 221 and the second hinge plates 212, 222 of the first fastening sheet 21 and the second fastening sheet 22 are triangular, and installation holes for the hinge shaft 3 are provided in the first hinge plates 211, 221 and the second hinge plates 212, 222.
[0018] In some examples, the sliding grooves 11 include a first sliding groove 111 and a second sliding groove 112 which are oppositely arranged and in communication with each other, the first fastening sheet 21 moving in the first sliding groove 111, and the second fastening sheet 22 moving in the second sliding groove 112. In this way, the fastener 2 moves stably.
[0019] The first sliding groove 111 is provided with a first inclined guide surface 113 for engaging the first fastening sheet 21 relative to the second fastening sheet 22, and the second sliding groove 112 is provided with a second inclined guide surface 114 for engaging the second fastening sheet 22 relative to the first fastening sheet 21, the first inclined guide surface 113 being opposite the second inclined guide surface 114. The retainer 1 is generally installed in a vertical direction. The first inclined guide surface 113 and the second inclined guide surface 114 are arranged on bottom side walls of the first sliding groove 111 and the second sliding groove 112 correspondingly. When an actuating positioner 4 moves the first fastening sheet 21 and the second fastening sheet 22 to the first inclined guide surface 113 and the second inclined guide surface 114 respectively, the first fastening sheet 21 is engaged relative to the second fastening sheet 22 when subjected to a pushing action of the first inclined guide surface 113, and meanwhile, the second fastening sheet 22 is engaged relative to the first fastening sheet 21 when subjected to a pushing action of the second inclined guide surface 114. In this way, the fastener 2 may be accommodated in the retainer 1.
[0020] In some examples, the retainer 1 is provided with a first sliding rail 12 and a second sliding rail 13 which are oppositely arranged and in communication with each other, a first end of the hinge shaft 3 moving in the first sliding rail 12, and a second end of the hinge shaft 3 moving in the second sliding rail 13. The first end and the second end of the hinge shaft 3 are provided with opposite sliding planes 31 separately, that is, the first end of the hinge shaft 3 is provided with the opposite sliding plane 31, the opposite sliding plane 31 being preferably arranged in parallel, and similarly, the second end of the hinge shaft 3 is provided with the opposite sliding plane 31, the opposite sliding plane 31 being preferably arranged in parallel. In this way, it may be ensured that the hinge shaft 3 moves along the first sliding rail 12 and the second sliding rail 13 without deviation.
[0021] At least one of opposite side walls of one ends, close to the first inclined guide surface 113 and the second inclined guide surface 114, of the first sliding rail 12 and the second sliding rail 13 is provided with a limiting protrusion point 14, the limiting protrusion point 14 dividing the first sliding rail 12 and the second sliding rail 13 into upper travel sections and lower travel sections, and the lower travel sections exactly accommodating the hinge shaft 3. Preferably, both opposite side walls of the first sliding rail 12 are provided with limiting protrusion points 14, and both opposite side walls of the second sliding rail 13 are provided with limiting protrusion points 14, the limiting protrusion points 14 arranged on the opposite side walls of the first sliding rail 12 and the limiting protrusion points 14 arranged on the opposite side walls of the second sliding rail 13 having the same height. When the hinge shaft 3 passes over the limiting protrusion point 14, a prompt sound is produced, and the hinge shaft 3 is limited in the lower travel sections of the first sliding rail 12 and the second sliding rail 13.
[0022] In some example, the locking assembly further includes an actuating positioner 4, the actuating positioner 4 being connected to the fastener 2 and capable of driving the fastener 2 to move and keeping the fastener 2 at a specific position. When the actuating positioner 4 drives the fastener 2 to move to different positions, the two fastening sheets have the relative disengagement state and the relative engagement state at different positions, and may be accommodated in the retainer 1 when in the relative engagement state, the limiting structure for keeping the two fastening sheets at the specific disengagement angle is arranged between the two fastening sheets, and the limiting structure keeps the two fastening sheets in the relative disengagement state.
[0023] Particularly, the actuating positioner 4 includes a bolt 41 and a threaded through hole 42 radially formed in the hinge shaft 3, the bolt 41 penetrating the retainer 1 to be connected to the threaded through hole 42. The bolt 41 is rotated to drive the hinge shaft 3 to move, and the hinge shaft 3 and the fastener 2 move in the sliding groove 11. When the bolt 41 stops rotating, the hinge shaft 3 stops moving, and the hinge shaft 3 is positioned at a specific position, so that the locking assembly has a simple structure and a low cost.
[0024] As shown in Fig. 3, when the locking assembly 10 is pre-assembled, the first fastening sheet 21, the second fastening sheet 22, and the hinge shaft 3 are installed in the retainer 1, the bolt 41 penetrates a support 20 and the retainer 1 to be in threaded connection with the threaded through hole 42 provided on the hinge shaft 3, and the first fastening sheet 21 is engaged relative to the second fastening sheet 22 and placed in the retainer 1. In such a condition, the hinge shaft 3 is limited in the lower travel sections of the first sliding rail 12 and the second sliding rail 13 and is limited by the limiting protrusion point 14, and thus the first fastening sheet 21, the second fastening sheet 22, and the hinge shaft 3 will not fall off and are integrally formed into a retainer 1 assembly, which is inserted into an installation hole of a toilet body 40.
[0025] As shown in Fig. 4, when the locking assembly 10 locks, the bolt 41 is screwed, to drive the hinge shaft 3, the first fastening sheet 21, and the second fastening sheet 22 to move, the hinge shaft 3 moves upwards along the first sliding rail 12 and the second sliding rail 13 after passing over the limiting protrusion point 14, and the first end and the second end of the hinge shaft 3 are provided with the opposite sliding planes 31 separately, so as to ensure that the hinge shaft 3 may move up and down along the first sliding rail 12 and the second sliding rail 13 of the retainer 1 without deviating or falling off. The first fastening sheet 21 and the second fastening sheet 22 are disengaged to two sides under the action of gravity. The hinge shaft 3 rises continuously, disengagement angles of the first fastening sheet 21 and the second fastening sheet 22 are gradually increased, and the first fastening sheet 21 and the second fastening sheet 22 are clamped to each other through the limiting structure and kept at a specific disengagement angle. In such a condition, the first fastening sheet 21 and the second fastening sheet 22 are disengaged by a maximum angle and cannot be disengaged any more, the bolt 41 is screwed continuously, the first fastening sheet 21 and the second fastening sheet 22 abut against a lower surface of the toilet body 40, and the locking assembly 10 completely locks.
[0026] As shown in Fig. 5, when the locking assembly 10 unlocks, the bolt 41 is unscrewed, to drive the hinge shaft 3, the first fastening sheet 21, and the second fastening sheet 22 to descend until the first fastening sheet 21 and the second fastening sheet 22 make contact with the first inclined guide surface 113 and the second inclined guide surface 114 of the retainer 1 respectively, and the first fastening sheet 21 and the second fastening sheet 22 are engaged inward to be closed. When the hinge shaft 3 passes over the limiting protrusion point 14 and the bolt 41 is pressed downwards, a prompt sound showing that the hinge shaft 3 retreats to an exact position is obviously sensed. Driven by the hinge shaft 3, the first fastening sheet 21 and the second fastening sheet 22 may be completely retracted into the retainer 1, to realize unlocking.
[0027] As shown in Fig. 6, the locking assembly 10 may be taken out integrally and reusable, and thus is rapidly disassembled and reusable.
[0028] Fig. 7 is a structural schematic diagram of the locking assembly 10, installed at a toilet. As shown in Fig. 7, a toilet includes a locking assembly 10, a support 20, and a cover plate 30. The support 20 is installed on a toilet body 40 by means of the locking assembly 10, and the cover plate 30 is installed on the support 20. The locking assembly 10 includes a retainer 1 and a fastener 2, the retainer 1 being provided with a sliding groove 11, the fastener 2 being formed by hinging two fastening sheets, the two fastening sheets being capable of moving in the sliding grooves 11, having a relative disengagement state and a relative engagement state, and being capable of being accommodated in the retainer 1 when in the relative engagement state, and a limiting structure for keeping the two fastening sheets at a specific disengagement angle being arranged between the two fastening sheets.
[0029] The support 20 is installed on the toilet body 40 by means of the locking assembly 10, and the cover plate 30 is installed on the support 20. The two fastening sheets of the locking assembly are used as locking abutments, to realize a locking function when in the relative disengagement state; the two fastening sheets may be accommodated in the retainer 1 when in the relative engagement state, to reduce an entire width of the two fastening sheets, and thus it is convenient to disassemble the retainer 1 and the fastener 2 integrally, and the locking assembly is rapidly disassembled and reusable.
