DETAILED DESCRIPTION
[0023] The following detailed description of the application is made with reference to the accompanying drawings. It is necessary to point out here that the following detailed description is only used to further illustrate the application and cannot be understood as limiting the scope of protection of the application. Those skilled in the art can make some non-essential improvements and adjustments to the application according to the above application content.
[0024] Referring to the drawings Figures 1-7 A door lock structure for sliding door, comprising a door handle 4 and a door locking piece 5, the door handle 4 is installed on the sliding door 3, the door locking piece 5 is vertically movably arranged on one side inside the sliding door 3, and a slot one 51 is formed on one side of the bottom of the door locking piece 5; the door handle 4 comprises a fixed handle 41 fixedly installed on the sliding door 3, an inner push handle 42 movably arranged on one side of the fixed handle 41, an inner cavity 421 arranged inside the inner push handle 42, an inner slot 422 arranged on the side wall of the inner cavity 421, a through slot 411 and an upper hook slot 412 arranged on the side of the fixed handle 41, a pusher 43 arranged inside the inner cavity 421, the pusher 43 comprising a push part 431, a positioning part 432 and an upper hook part 433, the push part 431 inserted into the inside of the slot one 51 after passing through the through slot 411, the positioning part 432 inserted into the inside of the inner slot 422, and the upper hook part 433 used for hooking in the upper hook slot 412.
[0025] Further, as shown in Figure 2 and Figure 3 , the door lock structure further comprises a blocking piece 7, the blocking piece 7 is fixedly connected inside the sliding rail 2 at the top of the sliding door 3, when the door is locked, the upper end of the door locking piece 5 is located on one side of the blocking piece 7 close to the door frame 1, and the upper end of the door locking piece 5 is in contact with the side wall of the blocking piece 7.
[0026] Further, as shown in Figure 6 , a slot hole 420 is formed on the side wall of the inner push handle 42, and a positioning piece 45 is arranged inside the slot hole 420, the positioning piece 45 is fixedly installed on the push part 431.
[0027] In this embodiment, the specific implementation is that: when the sliding door 3 is installed, as shown in Figure 1As shown, first install the door frame 1 and the sliding rail 2 on the top of the door frame 1, and then slide the upper end of the sliding door 3 into the sliding rail. The sliding door 3 is provided with two doors, and each sliding door 3 is provided with a door handle 4, a door locking piece 5 and a blocking piece 7. The state of the door being unlocked is shown in Figure 2 、 Figure 3 and Figure 5 As shown, the door locking piece 5 is located on the inner side of the sliding door 3, and the pushing piece 43 is located at the lower side of the slot 411. When the door is locked, the sliding door 3 is pushed to the left side, and then the inner push handle 42 is pushed upward, which drives the pushing piece 43 to move upward, and the pushing part 431 pushes the door locking piece 5 to move upward at the position of the slot one 51, so as to push the door locking piece 5 to the left side of the blocking piece 7 and contact with the side wall of the blocking piece 7. In this way, the blocking piece 7 blocks the door locking piece 5, achieving the purpose of locking the door. When unlocking, the inner push handle 42 is pushed downward, which drives the pushing piece 43 to move downward, and the pushing piece 43 drives the door locking piece 5 to move downward at the position of the slot one 51, so that the upper end of the door locking piece 5 is separated from the blocking piece 7, thereby achieving the purpose of unlocking.
[0028] In the locked state, the upper hooking part 433 is hooked in the inner side of the upper hooking slot 412. Only when the user pushes the inner push handle 42 downward, the upper hooking part 433 can move out of the upper hooking slot 412, which plays a role in preventing the door locking piece 5 from falling and causing accidental unlocking.
[0029] In this embodiment, as shown in Figure 5 The pushing piece 43 further includes a lower hooking part 434, which is symmetrically arranged on both sides of the pushing part 431, and the lower hooking slot 413 is formed on the lower side of the slot 411. The lower hooking part 434 is used to be hooked in the lower hooking slot 413.
[0030] Further, the two sides of the end of the fixed handle 41 are provided with fixed wings 414.
[0031] It should be noted that by arranging the lower hooking part 434 and the lower hooking slot 413, the door handle 4 can be arranged upside down, that is, the fixed wing 414 can be installed upward or downward, which can adapt to the habit of the user and also can prevent the door locking piece 5 from falling.
[0032] In this embodiment, as shown in Figure 2 、 Figure 3 、 Figure 4 and Figure 7 The outer push handle 44 is arranged on the side of the fixed handle 41 away from the inner push handle 42, and the outer push handle 44 is provided with a through hole 441, and the door locking piece 5 is provided with a slot two 52 aligned with the through hole 441.
[0033] It should be noted that when the door needs to be unlocked in an emergency outside the door, a tool such as a screwdriver, a wire, etc. can be inserted from the through hole 441, pass through the slot 52, and then push the door locking member 5 downward at the position of the slot 52, so that the door locking member 5 is separated from the blocking member 7, and the unlocking purpose is achieved.
[0034] In the embodiment, the door panel of the sliding door 3 is arranged at a middle position of the fixed handle 41, that is, the inner push handle 42 and the outer push handle 44 are respectively arranged at two sides of the door panel. The inner push handle 42 is arranged inside the door, and the outer push handle 44 is arranged outside the door.
[0035] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but it cannot be understood as the limitation of the utility model patent scope. It should be noted that for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model.
