[0029] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0030] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0032] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0033] See also Figures 1 to 6 The present embodiment discloses a hanging box, including a main box body 1 and a hanging rod 2, the main box body 1 is used to be fixed on the door body, the hanging rod 2 extends up and down, and the hanging rod 2 is connected to the hanging pulley; the main box body 1 is provided with a first elastic limiting tooth 112, and the first limiting tooth 112 extends up and down; the hanging rod 2 includes a connecting block 23 and a threaded rod 21, the threaded rod 21 is fixedly connected to the connecting block 23, the threaded rod 21 is used to be threadedly matched with the screw hole on the hanging pulley, and a plurality of second limiting teeth are provided on the outer peripheral side of the connecting block 23 231; wherein, when the first limiting tooth 112 is not deformed, the first limiting tooth 112 is engaged with the second limiting tooth 231 to limit the suspending rod 2 from rotating around its own axis, and the first limiting tooth 112 can move up and down relative to the second limiting tooth 231 to allow the main box body 1 to move up and down relative to the suspending rod 2; when the first limiting tooth 112 is deformed by the action of the second limiting tooth 231, the second limiting tooth 231 can move relative to the first limiting tooth 112 to allow the suspending rod 2 to rotate around its own axis.

[0034] The hanging box provided in the present embodiment applies a rotational torque to the hanging rod 2, and the second limiting tooth 231 engaged with the first limiting tooth 112 will apply a force to the first limiting tooth 112 at the contact position along the tangential direction of rotation, so that the first limiting tooth 112 is deformed to allow the second limiting tooth 231 to move relative to the first limiting tooth 112, that is, to allow the hanging rod 2 to rotate around its own axis, and the next second limiting tooth 231 in the rotation direction will be engaged with the first limiting tooth 112. In this way, by utilizing the threaded cooperation between the threaded rod 21 and the screw hole of the hanging pulley, the hanging rod 2 will synchronously move along its own axis relative to the hanging pulley during the process of deflecting the hanging rod 2 around its own axis by a certain angle, thereby changing the relative distance between the hanging pulley and the main box body 1 in the axial direction of the hanging rod 2, thereby achieving the purpose of adjusting the height of the hanging pulley, and the adjustment is simple and convenient;

[0035] It is understandable that, due to the long-term use of the door body, the threaded connection structure between the threaded rod 21 and the thread of the hanging pulley is prone to vibration or a small degree of impact, which easily leads to a gradual reduction in the preload force of the threaded connection structure. In this embodiment, a certain rotational torque is required to cause the first limiting tooth 112 to deform, so that the hanging rod 2 will move relative to the hanging pulley along its own axial direction. Therefore, when there is no need to adjust the relative distance between the hanging pulley and the main box body 1, the first limiting tooth 112 and the second limiting tooth 231 are engaged to generate resistance to limit the rotation of the threaded rod 21, thereby limiting the rotation of the threaded rod 21. In this way, the problem of looseness between the threaded rod 21 and the screw hole of the hanging pulley due to the decrease in preload force can be avoided, thereby effectively ensuring the stability of the hanging box with height adjustment function.

[0036] It can be understood that a lower pulley is provided at the lower part of the door body, the main box body 1 is fixed to the door body, and the main box body 1 is connected to the hanging pulley through the hanging rod 2. When debris falls into the lower track of the door system and the lower pulley passes through the debris, the door body will be suddenly lifted, thereby driving the main box body 1 to be suddenly lifted. Further, in this embodiment, if Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the first limit tooth 112 extends up and down. When the first limit tooth 112 is not deformed, that is, when no rotational torque is applied to the hanging rod 2, the first limit tooth 112 can move up and down relative to the second limit tooth 231 to allow the main box body 1 to move up and down relative to the hanging rod 2. As a result, when the door body jumps upward, the height of the hanging rod 2 remains unchanged, and the height of the hanging pulley connected to the threaded rod 21 remains unchanged, which can avoid the problem of the hanging pulley jumping upward due to the upward jumping of the door body, thereby realizing the anti-jumping of the hanging pulley, and the hanging pulley can maintain normal movement in the upper track. The wear of the threaded connection structure between the screw hole of the hanging pulley and the threaded rod 21 is also reduced, thereby ensuring the stability of the normal sliding operation of the door body. In addition, the up and down extension of the first limit tooth 112 can also increase the clamping stability between the first limit tooth 112 and the second limit tooth 231, thereby further improving the anti-loosening effect between the threaded rod 21 and the screw hole of the hanging pulley.

[0037] More specifically, in this embodiment, the axial direction of the suspension rod 2 is the up-down direction (see Figure 2 e1 direction).

[0038] like Figure 3 and Figure 5 As shown, further, in this embodiment, the hanging box also includes a first elastic member 3 arranged vertically, the upper end of the first elastic member 3 is abutted against the main box body 1, and the lower end of the first elastic member 3 is abutted against the connecting block 23. The first elastic member 3 is used to drive the connecting block 23 and the main box body 1 to move horizontally synchronously, that is, to drive the hanging rod 2 and the main box body 1 to move horizontally synchronously, and on the other hand, to reduce the upward jumping amount of the door body and the main box body 1. Specifically, the first elastic member 3 is in a compressed state. Under the pressure of the first elastic member 3, the horizontal friction between the lower end of the first elastic member 3 and the connecting block 23 is relatively large, and the horizontal friction between the upper end of the first elastic member 3 and the main box body 1 is also relatively large, so that the first elastic member 3 can drive the hanging rod 2 and the main box body 1 to move horizontally synchronously; when the door body drives the main box body 1 to jump upward, the first elastic member 3 is extended but still in a compressed state, and the first elastic member 3 can apply downward pressure to the main box body 1 to reduce the jumping amount of the main box body 1.

[0039] Preferably, in this embodiment, the first elastic member 3 is a spring; of course, in some other embodiments, the first elastic member 3 may also be, but is not limited to, elastic rubber, which can be selected according to actual conditions.

[0040] like Figure 3 , Figure 4 and Figure 5Preferably, in this embodiment, in order to improve the installation stability of the hanging box and make the overall structure of the hanging box more compact, a mounting groove 111 is provided in the main box body 1, the connecting block 23 is located in the mounting groove 111, the threaded rod 21 extends out of the mounting groove 111, the first limiting tooth 112 is provided on the groove wall of the mounting groove 111, the mounting groove 111 is connected to the limiting block 13, the first elastic member 3 is provided in the mounting groove 111, and the upper end of the first elastic member 3 is abutted against the limiting block 13.

[0041] like Figure 4 As shown, more preferably, in the present embodiment, two first limiting teeth 112 are provided, and the two first limiting teeth 112 are respectively provided on the two opposite groove walls of the mounting groove 111. When no rotational torque is applied, the second limiting teeth 231 on both sides of the connecting block 23 are respectively engaged with the two first limiting teeth 112 one by one to improve the engagement stability of the second limiting teeth 231 and the first limiting teeth 112, thereby further improving the anti-loosening effect between the threaded rod 21 and the screw hole of the hanging pulley.

[0042] It should be noted that, in some other embodiments, the first limiting teeth 112 may be, but are not limited to, provided with 3 or 4 teeth, etc., which can be selected according to actual conditions and is not limited here.

[0043] like Figure 3 and Figure 5 As shown, preferably, in the present embodiment, the sling rod 2 also includes a force-bearing section 22, wherein the force-bearing section 22 is preferably a regular tetrahedron, and can also be a regular pentahedron, and can also be a regular hexahedron, or the force-bearing section 22 is a cylinder provided with a knurled layer / friction layer, so that fingers or disassembly and assembly tools (such as wrenches, etc.) can more easily clamp and apply a rotational torque to the force-bearing section 22, so that the force-bearing section 22 rotates around its central axis.

[0044] More preferably, in this embodiment, the threaded rod 21 and the connecting block 23 are disposed at both ends of the force-bearing section 22, and the force-bearing section 22 is located below the threaded rod 21. The above-mentioned force-bearing section 22, connecting block 23, threaded rod 21 and a plurality of second limiting teeth 231 are integrally formed, and the force-bearing section 22 of the suspension rod 2 is at least partially exposed to the outside of the limiting seat of the carrier seat assembly. In this way, it is convenient to clamp the force-bearing section 22 and directly apply a rotational torque to the force-bearing section 22 to achieve the purpose of convenient height adjustment.

[0045] like Figure 3 , Figure 4 and Figure 5 As shown, preferably, in this embodiment, in order to improve the reasonable structural arrangement of the hanging box, the main box body 1 includes a mounting seat 11 and a fixing seat 12 which are fixedly connected and extend along the horizontal length direction, the mounting groove 111 is provided on the mounting seat 11, and the fixing seat 12 is used to connect the door body.

[0046] Preferably, in this embodiment, the hanging box also includes a fastener, and the fixing seat 12 is provided with a fastening channel 121 that penetrates and is inclined to the horizontal direction, and the fastener is inserted into the fastening channel 121 for fixing with the door body. Specifically, in this embodiment, the inner side wall of the fastening channel 121 is provided with a channel internal thread, and the channel internal thread is adapted to the fastening external thread of the fastener, and the fastener is threadedly connected with the channel internal thread; and when the hanging box needs to be detached or replaced from the door body, it is only necessary to loosen the fastener and detach it from the fastening channel 121, so that the hanging box and the door body can be quickly disassembled and replaced, which is beneficial to the subsequent update and maintenance of the door system.

[0047] It should be noted that in some other embodiments, the inner wall of the fastening channel 121 can be tapped using the fastening external thread of the fastener to form an internal channel thread on the inner wall of the fastening channel 121, which can also achieve the purpose of threaded connection between the fastener and the fastening channel 121. It can be selected according to actual needs and is not limited here.

[0048] like Figure 3 and Figure 5 As shown, preferably, in the present embodiment, the hanging box also includes a limiting bottom plate 4, the limiting bottom plate 4 is connected to the lower side of the mounting seat 11, the limiting bottom plate 4 is provided with a limiting protrusion 41, and the limiting protrusion 41 is opposite to the lower side wall of the connecting block 23; in this way, before the hanging box is installed to the door body, the limiting protrusion 41 abuts against the lower side wall of the connecting block 23 to limit the connecting block 23 in the mounting groove 111, thereby ensuring that the hanging rod 2 and the main box body 1 are a whole, which can prevent the hanging rod 2 from falling out of the main box body 1, and improve the overall assembly stability of the hanging box; after the hanging box is installed to the door body, the hanging rod 2 is connected to the hanging pulley, and the main box body 1 will move downward relative to the hanging rod 2 under the gravity of the door body, and at this time, a gap is formed between the limiting protrusion 41 and the lower side wall of the connecting block 23 to allow the main box body 1 to jump upward.

[0049] More preferably, in this embodiment, the mounting seat 11 is provided with a first connection hole 113 , the limiting base plate 4 is provided with a second connection hole 42 , and the hanging box further includes a fixing rod 5 extending up and down, and the fixing rod 5 is inserted into the first connection hole 113 and the second connection hole 42 .

[0050] Preferably, in this embodiment, the first limiting tooth 112 is a plastic structure, and thus, the elastic deformation of the first limiting tooth 112 itself is utilized to realize the above-mentioned action coordination between the first limiting tooth 112 and the second limiting tooth 231. Specifically, when the second limiting tooth 231 provides a certain external force acting on the first limiting tooth 112, the first limiting tooth 112 will produce elastic deformation under the force condition, and thus, the second limiting tooth 231 moves relative to the first limiting tooth 112, and when the next second limiting tooth 231 in the rotation direction is clamped with the first limiting tooth 112, the first limiting tooth 112 will elastically recover by itself, that is, the first limiting tooth 112 returns to its original state.

[0051] It should be noted that, in some other embodiments, the elasticity referred to above can also be that a second elastic member (such as a spring, etc.) is configured on the first limiting tooth 112, and the first limiting tooth 112 can be elastically extended and retracted along the radial direction of the suspension rod 2. Then, during the deflection of the second limiting tooth 231, the second limiting tooth 231 abuts against the tooth surface of the first limiting tooth 112. At this time, the second limiting tooth 231 will apply a force to the first limiting tooth 112, and the first limiting tooth 112 will shift in the direction away from the suspension rod 2 and the second elastic member will be compressed synchronously until the next second limiting tooth 231 in the rotation direction is engaged with the first limiting tooth 112. Under the action of the deformation recovery of the second elastic member, the first limiting tooth 112 will reset itself.

[0052] like Figure 1 and Figure 5 As shown, preferably, in this embodiment, the hanging box further comprises a protective shell 6, and the protective shell 6 is fixedly covered on the upper side of the main box body 1 to form protection.

[0053] In addition, this embodiment also provides a door system, including the hanging box as described above, and also including a hanging pulley, the hanging pulley is provided with a screw hole, and the threaded rod 21 is threadedly connected to the screw hole; the door system has all the advantages of the above-mentioned hanging box, which will not be repeated here.

[0055] 1) By using the threaded fit between the threaded rod 21 and the screw hole of the hanging pulley, the hanging rod 2 will synchronously move along its own axial direction relative to the hanging pulley during the process of deflecting a certain angle around its own axial direction, thereby changing the relative distance between the hanging pulley and the main box body 1 in the axial direction of the hanging rod 2, achieving the purpose of adjusting the height of the hanging pulley, and the adjustment is simple and convenient;

[0056] 2) The first limiting tooth 112 and the second limiting tooth 231 are engaged with each other to generate resistance to limit the rotation of the threaded rod 21, thereby limiting the rotation of the threaded rod 21. In this way, the problem of looseness between the threaded rod 21 and the screw hole of the hanging pulley due to the decrease of the pre-tightening force can be avoided;

[0057] 3) When the door body jumps upward, the main box body 1 can move up and down relative to the hanging rod 2, and the height of the hanging rod 2 remains unchanged, and the height of the hanging pulley connected to the threaded rod 21 remains unchanged, which can avoid the problem of the hanging pulley jumping upward due to the upward jumping of the door body, realize the anti-jumping of the hanging pulley, and reduce the wear of the threaded connection structure between the screw hole of the hanging pulley and the threaded rod 21;

[0058] 4) The first limiting tooth 112 extends up and down to increase the clamping stability between the first limiting tooth 112 and the second limiting tooth 231, thereby further improving the anti-loosening effect between the threaded rod 21 and the screw hole of the hanging pulley;

[0059] 5) The first elastic member 3 can be used to drive the connecting block 23 and the main box body 1 to move horizontally synchronously, that is, drive the suspension rod 2 and the main box body 1 to move horizontally synchronously, and can be used to reduce the upward jumping amount of the door body and the main box body 1 on the other hand.
