DETAILED DESCRIPTION
[0025] The technical scheme in the embodiments of the utility model will be apparently and completely described below with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the range of protection of the utility model.
[0026] Please refer to Figs. 1-3 The utility model provides a technical scheme: an anti-pinch type translation door structure, including door frame 1, install in the sliding rail 101 of door frame 1 lower extreme and upper extreme inner side, staggered activity installs two door body 2 between door frame 1 and sliding rail 101 and installs the pulley 201 on door body 2 upper end and lower end and with sliding rail 101 matching, the left end and right end between door body 2 and door frame 1 are provided with the anti-pinch mechanism for reducing the impact force when door body 2 closes.
[0027] Specifically, as Figs. 1-3 The utility model discloses a structure schematic diagram of the anti-pinch type translation door structure in the closed state.
[0028] The locking part comprises a sliding lock 4 vertically movably mounted in the middle of the anti-pinch sliding block 3 and facing the door frame 1, a lock catch 103 fixed to the inner side of the left end and the right end of the door frame 1 and facing the sliding lock 4, and a lock slot 401 formed on the outer side of the sliding lock 4 and locked with the lock catch 103. During the closing of the door body 2, the lock catch 103 on the door frame 1 can be slidably inserted into the lock slot 401 on the sliding lock 4, so as to transversely lock the door body 2 in the door frame 1 and prevent the transverse sliding of the door body 2. Moving the sliding lock 4 upward can make the lock slot 401 on the sliding lock 4 slide away from the lock catch 103 on the door frame 1, so as to realize the unlocking operation between the door body 2 and the door frame 1.
[0029] Specifically, as shown in Figs. 1-3 The limiting part is arranged between the door body 2 and the anti-pinch sliding block 3 to prevent the anti-pinch sliding block 3 from excessively sliding away from the door body 2. The limiting part comprises a first inner recessed catch groove 203 formed on the left end and the right end of the door body 2 and facing the anti-pinch sliding block 3, a limiting baffle 5 fixed to the outer side of the first inner recessed catch groove 203 and abutting with the side wall of the anti-pinch sliding block 3, and a second inner recessed catch groove 302 formed on the left end and the right end of the anti-pinch sliding block 3 and accommodating the limiting baffle 5. Under normal circumstances, under the action of the extrusion force of the helical compression spring 6, the anti-pinch sliding block 3 can elastically abut against the limiting baffle 5 on the door body 2 outward. The arrangement of the second inner recessed catch groove 302 on the anti-pinch sliding block 3 can make the lateral abutment between the anti-pinch sliding block 3 and the door body 2 more flat, and improve the assembly appearance and surface flatness of the door body 2 and the anti-pinch sliding block 3.
[0030] Meanwhile, the limiting baffle 5 is fixedly connected with two fixing blocks 501 penetrating through the door body 2 in the direction symmetrical to the first inner recessed catch groove 203. The door body 2 is provided with a mounting hole 204 for accommodating the fixing blocks 501. A fixing screw 502 is threadedly installed between the mounting hole 204 and the fixing block 501. The limiting baffle 5 can be pre-inserted into the mounting hole 204 on the door body 2 through the fixing block 501, and the limiting baffle 5 can be integrally positioned and installed into the first inner recessed catch groove 203 of the door body 2. After the fixing screw 502 is screwed into the mounting hole 204 and the fixing block 501, the limiting baffle 5 can be stably fixed on the door body 2, so as to block the excessive outward sliding of the anti-pinch sliding block 3 in the door body 2 and limit the sliding area of the anti-pinch sliding block 3.
[0031] Working principle: when using, the door body 2 is closed, and gradually moves to the side of the door frame 1, the flexible rubber strip 102 on the door frame 1 can be pre-inserted into the middle groove 301 of the anti-pinch sliding block 3, in the process of the flexible rubber strip 102 entering the middle groove 301, the impact force is first reversely flexibly resisted, and under the action of the impact force, the anti-pinch sliding block 3 can slide inward in the transverse sliding groove 202 of the door body 2, the anti-pinch sliding block 3 can extrude the spiral extrusion spring 6 inward, the spiral extrusion spring 6 can be forced to shrink inward, the impact force of the door body 2 closing is secondly flexibly resisted, the impact force and the sound of the door body 2 closing can be reduced, so that the damage or pinch injury of the door body 2, the door frame 1 and the user's limbs can be reduced.
[0032] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
