DETAILED DESCRIPTION

[0026] The utility model will be further explained in combination with the drawings and specific embodiments, so that the person skilled in the art can better understand the utility model and can be implemented, but the embodiment is not as the limitation of the utility model.

[0027] Referring to Figure 1 - Figure 7 The utility model discloses a mobile door lock catch, including fixed plate one 11, the rectangular sleeve one 113 is fixedly installed on the outside surface of fixed plate one 11, the fixed plate two 111 is set up on the one side edge position of fixed plate one 11, the rectangular sleeve two 114 is set up on the outside surface of fixed plate two 111, the outside surface of limiting rod two 119 is fixedly connected on the outside surface of rectangular sleeve one 113, the circular ring 12 is movably sleeved on the outside surface of limiting rod two 119, the butt joint groove 13 is seted up on the outside surface of circular ring 12, the limiting sleeve 112 is fixedly connected on the outside surface of fixed plate two 111, the outside surface of rectangular sleeve two 114 is movably sleeved in the inner side wall of limiting sleeve 112, the position of rectangular sleeve two 114 is set on the bottom edge position of rectangular sleeve one 113, the limiting rod one 115 is fixedly connected on the one side edge position of rectangular sleeve one 113, the swing arm 116 is movably sleeved on the outside surface of limiting rod one 115, the arc-shaped lapping plate 117 is fixedly connected on one end of swing arm 116, the arc-shaped lapping plate 117 is fixedly connected on the inner side wall of multiple butt joint protruding blocks 118, the outside surface of butt joint protruding block 118 is movably sleeved on the inner side wall of butt joint groove 13;

[0028] After the door is closed, the rectangular sleeve two 114 is moved on the inner side wall of the limiting sleeve 112 towards the direction of the rectangular sleeve one 113, when the rectangular sleeve two 114 moves along the bottom surface of the rectangular sleeve one 113, one end surface of the rectangular sleeve two 114 will extrude the surface of the circular ring 12, at this time, the limiting rod two 119 limits the moving position of the circular ring 12, when the rectangular sleeve two 114 slides and extrudes on the bottom surface of the circular ring 12, the inner side wall of the circular ring 12 will turn and lift upwards around the surface of the limiting rod two 119, when the surface of the rectangular sleeve two 114 completely passes the surface of the circular ring 12, the circular ring 12 will vertically descend under the gravity of itself and fall into the interior of the rectangular sleeve two 114, when the rectangular sleeve two 114 retracts, the inner side wall of the rectangular sleeve two 114 will push the surface of the circular ring 12, because the position of the circular ring 12 is close to the inner side wall of one end of the rectangular sleeve one 113, and the circular ring 12 cannot vertically move upwards, it cannot slide out of the rectangular sleeve two 114 and the rectangular sleeve one 113 under the block of the rectangular sleeve one 113.

[0029] Referring to Figure 1 - Figure 7 As shown in the utility model, in one embodiment of the utility model, a triangular angle is arranged at the joint of the circular ring 12 and the rectangular sleeve one 113, the position of the circular ring 12 is movably sleeved on the inner side wall of the rectangular sleeve one 113, the outer side surface of the circular ring 12 is movably sleeved on the inner side wall of the rectangular sleeve two 114, the position of the rectangular sleeve two 114 is arranged on the outer side surface of the fixed plate one 11, the outer side surface of one end of the rectangular sleeve one 113 is movably connected on the outer side surface of the fixed plate two 111, and the outer side surface of the circular ring 12 is movably connected on the outer side surface of the joint of the fixed plate one 11 and the fixed plate two 111.

[0030] When the circular ring 12 is clamped into the interior of the rectangular sleeve two 114, the swinging arm 116 swings on the surface of the limiting rod one 115, and the arc-shaped connecting plate 117 at one end of the swinging arm 116 is connected on the top surface of the circular ring 12, at this time, the joint blocks 118 on the inner side wall of the arc-shaped connecting plate 117 are clamped into the inner side wall of the joint groove 13, because the joint blocks 118 are jointed with the joint groove 13, when the circular ring 12 vertically moves upwards, the circular ring 12 cannot push and extrude the arc-shaped connecting plate 117 under the limitation of the joint blocks 118 at different angles, and the circular ring 12 cannot turn around the limiting rod two 119 as the center point when the rectangular sleeve two 114 moves back, thereby the circular ring 12 is firmly positioned on the surface of the limiting rod two 119.

[0031] Principle: after the door is closed, cooperate with the rectangular ring 2 114 on the inside wall of the limiting sleeve 112 to move in the direction of the rectangular ring 1 113, when the rectangular ring 2 114 moves along the bottom surface of the rectangular ring 1 113, one end surface of the rectangular ring 2 114 will extrude the surface of the circular ring 12, at this time cooperate with the limiting rod 2 119 to limit the moving position of the circular ring 12, when the rectangular ring 2 114 slides and extrudes on the bottom surface of the circular ring 12, the inside wall of the circular ring 12 will turn and lift upwards around the surface of the limiting rod 2 119, when the surface of the rectangular ring 2 114 completely passes the surface of the circular ring 12, the circular ring 12 will vertically descend under its own gravity and fall into the inside of the rectangular ring 2 114, when the rectangular ring 2 114 retracts, the inside wall of the rectangular ring 2 114 will push the surface of the circular ring 12, because the position of the circular ring 12 is close to the one end inside wall of the rectangular ring 1 113, and the circular ring 12 cannot vertically move upwards, it cannot slide out of the rectangular ring 2 114 and the rectangular ring 1 113 under the block of the rectangular ring 1 113;

[0032] When the circular ring 12 is clamped into the inside of the rectangular ring 2 114, cooperate with the swing arm 116 to swing on the surface of the limiting rod 1 115, and clamp the arc-shaped lap plate 117 on one end of the swing arm 116 on the top surface of the circular ring 12, at this time clamp the butt joint block 118 on the inside wall of the arc-shaped lap plate 117 into the inside wall of the butt joint groove 13, because the butt joint block 118 and the butt joint groove 13 are butted after the butt joint, when the circular ring 12 vertically moves upwards, it cannot push and extrude the arc-shaped lap plate 117 due to the limitation of the multiple butt joint blocks 118 at different angles, and the circular ring 12 cannot turn around the limiting rod 2 119 when the rectangular ring 2 114 moves back, so that the circular ring 12 is firmly positioned on the surface of the limiting rod 2 119.

[0033] Obviously, the above embodiments are only examples for clear illustration, and are not a limitation on the embodiments. For ordinary skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, all the embodiments need not and cannot be exhausted. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
