UTILITY MODEL CONTENT

[0004] The utility model discloses a hole curtain cloth sealing structure to solve the problem in the background art.

[0005] To achieve the above object, the utility model provides the following technical scheme: a hole curtain cloth sealing structure, including curtain cloth, mobile seat and extrusion ring, the curtain cloth is fixedly connected with the symmetry of a plurality of supporting blocks, the supporting block is fixedly connected with the mounting bracket, the mounting bracket is rotatably connected with the lead screw, the supporting block is fixedly connected with the guide block, the supporting block is fixedly connected with the mounting ring, the mounting ring is rotatably connected with a plurality of pressing tablets of array arrangement, the pressing tablet is equipped with the pressure slot, the mobile seat is equipped with the extrusion slot.

[0006] Preferably, the mobile seat is provided with a guide groove at the position corresponding to the guide block, and the guide block is slidably connected in the corresponding guide groove.

[0007] Preferably, the lead screw is threadedly connected with the corresponding mobile seat.

[0008] Preferably, the extrusion ring is located in the inside of the pressure slot and the extrusion slot.

[0009] Preferably, the mounting bracket is provided with an L-shaped structure, and the guide block is provided with a T-shaped structure.

[0010] Compared with the prior art, the utility model has the beneficial effects that: by moving the extrusion ring, multiple pressing tablets can be pressed at the same time, the pressed pressing tablet will rotate and compact to the curtain cloth direction, thereby completing the compact sealing of the curtain cloth, greatly reducing the input amount of existing resources, and only rotating the specific lead screw during operation can realize the compact sealing of the curtain cloth, and the operation convenience and practicality are high.

[0016] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0017] Please refer to Figures 1-4 The utility model provides a kind of technical scheme: a hole door curtain fabric sealing structure, including curtain fabric 1, mobile seat 2 and extrusion ring 3, curtain fabric 1 is fixedly connected with the multiple support blocks 4 of symmetrical arrangement, support block 4 is all fixedly connected with mounting bracket 5, mounting bracket 5 is all rotatably connected with screw 6, support block 4 is all fixedly connected with guide block 7, support block 4 is commonly fixedly connected with mounting ring 8, mounting ring 8 is rotatably connected with the multiple pressing pieces 9 of array arrangement, pressing piece 9 is all provided with pressure receiving groove 10, mobile seat 2 is all provided with extrusion groove 11.

[0018] Mobile seat 2 is all provided with guide groove 12 at the position corresponding to guide block 7, guide block 7 is all slidably connected in the inside of corresponding guide groove 12, the connection of guide groove 12 and guide block 7 is convenient for the movement of mobile seat 2 to guide, screw 6 is all threadedly connected with corresponding mobile seat 2, when screw 6 rotates, it is convenient to drive mobile seat 2 to move, extrusion ring 3 is located in the inside of pressure receiving groove 10 and extrusion groove 11, extrusion ring 3 is conveniently extruded by extrusion groove 11, and then extrusion action is carried out to pressure receiving groove 10, the specific shape of mounting bracket 5 is all L-shaped arrangement, the specific shape of guide block 7 is all T-shaped arrangement.

[0019] Specific, use the utility model, can cover the curtain fabric 1 on the door, and then rotate each lead screw 6, the lead screw 6 rotation will drive the moving seat 2 to the direction of curtain fabric 1 movement, the movement of moving seat 2 will make extrusion groove 11 extrude extrusion ring 3, at this time extrusion ring 3 will move with moving seat 2 together, and the extrusion ring 3 that moves again will extrude each pressing piece 9 on the pressure groove 10, at this time the pressure groove 10 is extruded and will make the pressing piece 9 with mounting ring 8 as center of rotation to the direction of curtain fabric 1, the pressing piece 9 that rotates finally will all be extruded to the surface of curtain fabric 1, so that the curtain fabric 1 is firmly attached to the door, complete the compaction sealing work of curtain fabric 1, greatly reduce the input of existing resources, and only the specific lead screw 6 is rotated when operating can realize the compaction sealing of curtain fabric 1, and the operation convenience and practicality are higher.
