Description

Technical Field

[0001] This utility model relates to the field of door curtain technology, specifically an assembled PVC soft door curtain. Background Technology

[0002] PVC flexible door curtains, as a common door partition device, are widely used in many places such as industrial plants, supermarkets, cold storage, and logistics warehouses due to their advantages such as low cost, light weight, good heat and sound insulation, and a certain degree of flexibility and transparency. Traditional PVC flexible door curtains usually adopt an integrated design or are fixed to the bracket through structures such as hanging rings. However, in practical applications, these traditional design methods have gradually revealed many limitations.

[0003] Due to their large overall size, integrated PVC soft curtains require significant manpower and time to install and dismantle. Installation involves lifting the entire curtain and securing it to a bracket; this is particularly difficult for large or heavy curtains, requiring multiple people to work together, increasing installation costs and complexity. Dismantling presents similar challenges, and improper handling during dismantling can easily damage the curtain, affecting its lifespan.

[0004] Multi-panel PVC soft curtains installed with hanging rings, while solving the connection problem between the curtain and the bracket to some extent, are prone to loosening or damage due to external forces when the curtain is lifted, causing the curtain to fall and posing a safety hazard. This is especially true in places with high pedestrian traffic and frequent curtain use, such as supermarket entrances and logistics warehouse passageways, where a falling curtain can not only disrupt normal passage and use but also potentially cause injury to people and property.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 and Figure 2An assemblable PVC soft door curtain may include a hanging frame 10, a cover plate 20, at least one bracket 30, and multiple curtain sections 40. The cover plate 20 covers the underside of the hanging frame 10, and the hanging frame 10 and the cover plate 20 cooperate to connect and assemble the multiple curtain sections 40, allowing the multiple curtain sections 40 to be detachably installed under the hanging frame 10 and arranged in a row to cover a doorway. The bracket 30 is inserted above the hanging frame 10, and the bracket 30 and the hanging frame 10 are fixed to the cover plate 20 by bolts, so that the hanging frame 10 and the cover plate 20 are assembled as a single unit. Alternatively, the bracket 30 can be fixed to the building using expansion bolts or other fasteners, allowing the hanging frame 10 and the cover plate 20 to be pre-installed via at least one bracket 30.

[0025] See Figure 3 The mounting frame 10 has an internal number of insertion parts 11 equal to the number of curtain parts 40. Each insertion part 11 has a bottom with an interconnected limiting groove 12 and a guide groove 13. The limiting groove 12 is a round hole, and the guide groove 13 is a rectangular hole. The end of the guide groove 13 facing away from the limiting groove 12 passes through the side wall of the mounting frame 10. The limiting groove 12 and the guide groove 13 are used to cooperate with the installation of the curtain part 40.

[0026] See Figure 4 The cover plate 20 has an equal number of rotating grooves 21 as the limiting grooves 12, and also has an equal number of insertion grooves 22 as the guiding grooves 13. Each rotating groove 21 is located below a limiting groove 12 and is coaxially distributed with it, and the diameter of the rotating groove 21 is smaller than the diameter of the limiting groove 12. Each insertion groove 22 is located below a guiding groove 13 and communicates with the adjacent rotating groove 21, and the end of the insertion groove 22 facing away from the rotating groove 21 penetrates the side wall of the cover plate 20. The rotating grooves 21 and the insertion grooves 22 are also used to cooperate with the installation of the curtain part 40.

[0027] See Figure 5 The bracket 30 is shaped like a "Π". Several countersunk holes 31 are formed on the top of the bracket 30. Connecting holes 23, coaxially distributed with the countersunk holes 31, are formed on the cover plate 20. Bolts can be inserted into the countersunk holes 31 and connecting holes 23, and by tightening with nuts, the cover plate 20 can be fixed below the lifting frame 10. Several lifting frame assembly holes 32 are provided on the side of the bracket 30. Screws are inserted into the lifting frame assembly holes 32 to connect and secure it to the lifting frame 10. Lifting installation holes 33 are also provided at the four corners of the top of the bracket 30. Bolts can be inserted into the lifting installation holes 33 and, in conjunction with expansion tubes pre-installed on the building, the bracket 30 can be fixed to the building as a whole.

[0028] See Figure 6The curtain section 40 may include a crossbeam 41, a protruding post 42, an insert block 43, a PVC curtain body 44, and two weight strips 45. The upper end of the PVC curtain body 44 is inserted below and fixedly connected to the crossbeam 41, and weight strips 45 with a length adapted to the length of the PVC curtain body 44 are fixedly connected to both opposite sides of the PVC curtain body 44. The protruding post 42 is formed at the top center of the crossbeam 41, and the insert block 43 is formed at the top of the protruding post 42. The insert block 43 is elliptical or oblong, and the length of the insert block 43 is adapted to the diameter of the limiting groove 12, and the width of the insert block 43 is adapted to the width of the guide groove 13. The protruding post 42 is cylindrical, and the diameter of the protruding post 42 is smaller than the diameter of the rotating groove 21 and the width of the insertion groove 22.

[0029] When installing the curtain section 40, the insert 43 can be inserted into the guide groove 13 along its length. After the insert 43 enters the limiting groove 12, it is deflected by 90 degrees, so that the insert 43 is locked against the inner wall of the limiting groove 12. During this process, the protrusion 42 first enters the rotating groove 21 from the insertion groove 22, and then can be deflected by 90 degrees in the rotating groove 21. After the insert 43 is inserted into the limiting groove 12 through the guide groove 13, and the curtain section 40 is locked by the deflection of the insert 43 in the limiting groove 12, the installation of the curtain section 40 is completed. During use after the curtain section 40 is installed, when the PVC curtain 44 is lifted, the limiting groove 12 restricts the position of the insert 43, which can prevent the curtain section 40 from falling off the hanging frame 10.

[0030] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
