[0037] The embodiments of the present utility model will be further described below with reference to the accompanying drawings.
[0038] According to some embodiments of the present utility model, referring to Figures 1 to 4 , the turntable 300 - type door lock assembly includes a housing 100, a lock rod 200, a turntable 300, and a driving component 400. A lock hole 101 communicating with the inner cavity of the housing 100 is provided on the left - hand side wall of the housing 100. The lock rod 200 is arranged in the housing 100 and is slidably connected to the housing 100. The lock rod 200 can slide in the left - right direction. A limiting post 210 is provided on the rear side surface of the lock rod 200. The turntable 300 is arranged in the housing 100 and is rotatably connected to the housing 100. The turntable 300 is provided with a limiting hole 310. The two ends of the limiting hole 310 extending along the disk surface of the turntable 300 are respectively a first end 311 and a second end 312. The limiting post 210 is inserted into the limiting hole 310. The driving component 400 is arranged in the housing 100. The driving component 400 is used to drive the turntable 300 to rotate around its own axis. The rotation of the turntable 300 can drive the limiting post 210 to move along the extending direction of the limiting hole 310, so that the limiting post 210 reciprocates between the first end 311 and the second end 312 and drives the lock rod 200 to reciprocate in the left - right direction.
[0039] Referring to Figure 2 and Figure 3 , when the door needs to be locked, the driving component 400 drives the turntable 300 to rotate, so that the limiting column 210 moves along the extending direction of the limiting hole 310 to the first end 311, thereby driving the lock rod 200 to move leftward to extend out of the housing 100 and enter the lock groove 420 of the door frame 410, thus completing the door locking.
[0040] Referring to Figure 2 and Figure 3 , when the door needs to be opened, the driving component 400 drives the turntable 300 to rotate, so that the limiting column 210 moves along the extending direction of the limiting hole 310 to the second end 312, driving the lock rod 200 to move rightward so that the lock rod 200 retracts back into the housing 100 and thus disengages from the lock groove 420.
[0041] The turntable 300 - type door lock assembly has a simple structure and reliable operation, can reduce the volume and weight of the door lock assembly, and has simple assembly and low cost.
[0042] Furthermore, referring to Figure 3 , a sliding groove 102 extending in the left - right direction is provided in the housing 100, the lock rod 200 is arranged in the sliding groove 102, and the upper side wall and the lower side wall of the sliding groove 102 jointly limit the lock rod 200 from moving in the up - down direction, and the sliding groove 102 can move the lock rod 200 in the left - right direction to avoid deviation.
[0043] Furthermore, referring to Figure 2 and Figure 3 , a lock part 220 is provided at one end of the lock rod 200, and the sliding of the lock rod 200 can make the lock part 220 extend out of the housing 100 and insert into the lock groove 420 of the door frame 410. The sliding of the lock rod 200 can drive the lock part 220 to retract into the housing 100.
[0044] Furthermore, referring to Figure 2 and Figure 3 , a groove 103 is provided in the housing 100, a convex column 320 is provided in the middle of the front side of the turntable 300, and the convex column 320 is inserted into the groove 103, so that the turntable 300 is rotatably connected to the housing 100. Preferably, a bearing is provided between the convex column 320 and the groove 103 to reduce the friction between the turntable 300 and the housing 100.
[0045] Furthermore, referring to Figure 2 and Figure 4 , a positioning groove 330 is provided in the middle of the rear side of the turntable 300, and the driving end of the driving component 400 is inserted into the positioning groove 330 and fixedly connected to the turntable 300.
[0046] Furthermore, referring to Figure 4, the limiting hole 310 is arc-shaped, and the distance between the first end 311 and the center of the turntable 300 is greater than the distance between the second end 312 and the center of the turntable 300. It can be understood that when the limiting post 210 moves to the first end 311, the distance between the locking lever 200 and the center of the turntable 300 is the largest, and at this time, one end of the locking lever 200 extends out of the housing 100. When the limiting post 210 moves to the second end 312, the distance between the locking lever 200 and the center of the turntable 300 is the smallest, and at this time, the locking lever 200 retracts into the housing 100.
[0047] Furthermore, referring to Figure 1 and Figure 3 , the housing 100 includes a housing body 110 and a housing cover 120, and the housing body 110 and the housing cover 120 are detachably connected. The housing body 110 is provided with a plurality of first connecting posts 111, and the first connecting posts 111 are provided with first threaded holes 112. The housing cover 120 is provided with a plurality of first through holes 121. The turntable 300 type door lock assembly further includes a plurality of bolts 130. The plurality of first connecting posts 111, the plurality of first through holes 121 and the plurality of bolts 130 correspond to each other one by one. The bolts 130 pass through the first through holes 121 and are then threadedly connected to the first threaded holes 112, so that the housing body 110 and the housing cover 120 are relatively fixed.
[0048] Furthermore, the housing body 110 is provided with a plurality of second connecting posts 113, and the second connecting posts 113 are provided with second threaded holes 114. The housing cover 120 is provided with a plurality of second through holes 122. One end of the second connecting post 113 passes through the second through hole 122, and the second threaded hole 114 is used for connecting with the cabinet door. When it is necessary to fixedly install the turntable 300 type door lock assembly on the cabinet door, bolts 130 are used to pass through the cabinet door and be threadedly connected to the second threaded holes 114.
