Detailed Description

Referring to fig. 1 to 5, the hinge seat of toilet cover plate includes a screw rod 10, a nut 20, a fixing frame 30 and a fastening member 40, wherein the fixing frame 40 is vertically disposed, the nut 20 is in a column shape and horizontally disposed in the fixing frame 40, a screw hole 22 vertically penetrating is disposed in the middle of the fixing frame, the fastening member 40 is movably sleeved outside the fixing frame 30 and above the nut 20, the screw rod 10 is screwed in from the top surface of the fixing frame 30 and is screwed with the screw hole 22 so as to drive the nut to vertically reciprocate in the fixing frame, the nut 20 moves upward to push the fixing frame 30 which is originally obliquely disposed and then moves upward and horizontally in a substantially horizontal posture, so that the fixing frame 30 can be matched and locked with a toilet seat body 50 (i.e., a ceramic body). Specifically, the left and right sides of the fixing frame 30 are symmetrically provided with vertically extending windows 32 (the windows are communicated with the inner cavity, so that the limiting blocks can contact with the screw rods), and the rear side is provided with a positioning hook 34 (preferably arranged in the middle of the rear side). The fastening member 40 includes two clamping pieces 41 arranged in bilateral symmetry and a connecting piece 42 connecting the two clamping pieces, the connecting piece 42 is connected with the rear part of the clamping piece 41, the lower edge of the front part of the clamping piece 41 is a guiding inclined edge 43, and the front part is also provided with a limiting block 44 protruding inwards (inside the fastening member). The distance between the two tabs 41 is greater than the diameter of the screw 10 so that the screw can pass between the two tabs. The distance between the stoppers 44 of the two locking pieces 41 is smaller than the diameter of the screw 10, so that the screw can restrict the fastener 40 in the lateral direction. The connecting piece 42 is located above the positioning hook 34, the two locking pieces 41 are respectively located at the left and right sides of the fixing frame 30, the two limiting blocks 44 are respectively accommodated in the two windows 32, and the connecting piece 42 and the limiting blocks 44 are respectively located at the front and rear sides of the screw 10, so that the fixing frame 30 can be prevented from moving back and forth or swinging up and down in a horizontal state, and a good levelness can be maintained. The nut 20 is located at the lower part of the fixing frame 30 and two ends of the nut respectively extend outwards from two windows 32, and the purpose of the extending is that the nut can jack up the guiding bevel edge 43 of the card after rising. It will be appreciated that in practice the nut 20 will also be able to lift the card so long as one end extends outside the window.

Naturally, the positioning hook 34 catches the connecting piece 42, the front end of the fastening member 40 swings downward until the screw 10 blocks the limiting block 44, the fixing frame 30 is integrally disposed in an inclined manner, and the guiding bevel edge 43 is located right above the nut 20 (as shown in fig. 2). During locking, the screw 10 is rotated to lift the nut 20, the nut 20 gradually lifts the front end of the fixing frame 30 after contacting the bevel guiding edge 43 (as shown in fig. 3), after the nut 20 integrally slides over the bevel guiding edge 43, the fixing frame 30 is rotated to be substantially horizontally arranged (as shown in fig. 4), meanwhile, the rear side of the fixing frame 40 blocks the connecting piece 42 to prevent the fastening piece 40 from moving forward, the screw 20 abuts against the limiting block 44 to prevent the fastening piece 40 from moving backward (at this time, the positioning hook is just supported below the connecting piece), then, the screw 10 is continuously rotated to lift the nut 20, and finally, the fixing frame 30 is matched with the toilet seat 50 to realize locking and fixing. It will be appreciated that when it is desired to unlock, the screw 10 is loosened to lower the nut 20, the holder 30 is initially moved down horizontally until the retainer hooks 34 catch the tabs 42 (as shown in fig. 4), and after the nut continues to be lowered, the front end of the fastener 40 is swung down (as shown in fig. 3), and finally the nut 20 is lowered to the bottom (as shown in fig. 2), returning to the original state.

Preferably, the positioning hook 34 is disposed upwardly and the attachment tab 42 is attached to the lower edge of the rear portion of the card 41. Thus, the positioning hook 34 can more stably and easily catch the connecting piece 42, and the larger the upward tilting degree of the rear end of the fastening member 40 is, that is, the more inclined the fastening member 40 can be, so as to facilitate the installation of the fastening member 40 from above the toilet seat 50. In fact, the connecting piece can be hung as long as the positioning hook protrudes out of the side face of the fixing frame, and therefore the positioning hook can also extend out horizontally.

Preferably, the stop 44 is located at the upper edge of the card 41. The greater the extent to which the front end of the fastener 40 can be swung down, i.e., the more the fastener 40 can be tilted, which also facilitates installation of the fastener 40 from above the toilet seat 50.

Preferably, the lower edge of the middle portion of the locking piece 41 is provided with a groove 45, and the nut 20 integrally slides over the guiding bevel 43 and then enters the groove 45 during locking. So that the nut 20 can more smoothly push the fastener 40 upward.

Preferably, the fastener 40 is a unitary piece. Of course, the device can be a stamping part or an injection molding part.

Preferably, the fixing frame 30 includes an upper top base 35, a lower base 36, a front pillar 37 and a rear pillar 38 connected between the upper top base and the lower base, the upper top base 35 is provided with a through hole for the screw rod 10 to pass through, the positioning hook 34 is provided on the rear pillar 38, and a gap between the left side edges and a gap between the right side edges of the front pillar 37 and the rear pillar 38 respectively form the window 32. The screw rod 10 is directly utilized to limit the fastener 30, so that the integral structure of the fixing frame 30 can be simplified, the fastener 40 can be integrally arranged on the fixing frame 30, and the assembly is easy.

Preferably, the lower base 36 is provided with a relief hole for the screw 10 to pass through. That is, when the screw 10 is screwed, the lower portion of the screw can pass through the lower portion of the offset hole, so that the height of the fixing frame 30 can be made smaller.

Preferably, the mount 30 is a unitary injection molded piece.

The above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention should not be limited by this description, and all equivalent changes and modifications made within the scope and the specification of the present invention should be covered by the present invention.
