Abstract
Description
Technical Field
[0001] This utility model relates to the field of enclosure panels, and more particularly to an impact-resistant enclosure panel. Background Technology
[0002] Fencing is a type of enclosure made of plastic material, commonly used at construction sites, event venues, temporary exhibitions, and other similar locations to demarcate areas, ensure security, provide privacy, or prevent items from being moved or lost. They are typically lightweight, easy to install and dismantle, and possess good weather resistance and durability.
[0003] In the process of developing this application, the inventors discovered the following problems with the existing technology: Conventional fence panels are generally connected by a plug-in method. However, this method can be relatively troublesome to disassemble when the fence layout needs to be changed, especially when multiple adjustments are required, which can easily affect work efficiency. In addition, the plug-in connection method is relatively simple, so when subjected to large external forces (such as wind), the connection is not strong enough and is prone to loosening or falling off.
[0004] Therefore, those skilled in the art have provided an impact-resistant enclosure to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose an impact-resistant enclosure. This new model has strong impact resistance and is easy to disassemble.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] An impact-resistant enclosure includes two enclosure bodies and a connecting mechanism. Placement boxes are fixedly installed on both sides of the two enclosure bodies. The connecting mechanism includes a first connecting post, a second connecting post and two top covers. A hollow post is fixedly installed on one side of the first connecting post and a fixing post is fixedly installed on one side of the second connecting post. Threaded holes are opened at the upper ends of the first and second connecting posts.
[0008] Both of the top covers have threaded posts threaded into their inner ends, and both top covers have connecting blocks fixedly installed on opposite sides.
[0009] Furthermore, the two enclosure bodies each include two wear-resistant layers, and a support layer and a buffer layer are respectively provided on opposite sides of the two wear-resistant layers.
[0010] Furthermore, the two wear-resistant layers are made of polycarbonate, and the support layer is made of high-density polyethylene.
[0011] Furthermore, the buffer layer is made of foamed polypropylene, and the two wear-resistant layers are connected to the support layer and the buffer layer by adhesive.
[0012] Furthermore, the first connecting post is placed in the placement box of one of the enclosure panels, and the second connecting post is placed in the placement box of the other enclosure panel.
[0013] Furthermore, the two top covers are placed on the upper ends of the first connecting post and the second connecting post, and the two threaded posts are respectively threaded into the inner ends of the two threaded holes.
[0014] Furthermore, the two connecting blocks are hinged together, and the fixing post is placed inside the hollow post.
[0015] This utility model has the following beneficial effects:
[0016] 1. This utility model proposes an impact-resistant enclosure. The two outermost wear-resistant layers of the enclosure body are made of polycarbonate, which has good scratch resistance and wear resistance, effectively extending the service life of the enclosure and reducing the frequency of maintenance and replacement. The support layer is made of high-density polyethylene, providing strong support to ensure the enclosure remains stable under stress, reducing deformation and enhancing the overall structural integrity. The buffer layer is made of foamed polypropylene, which can absorb impact force, reduce the impact of external impact on the enclosure and its support structure, and protect the integrity of the enclosure under harsh conditions. The wear-resistant layer, support layer and buffer layer are connected by adhesive to improve the bonding strength between the layers, making them form a whole and effectively improving the impact resistance of the enclosure.
[0017] 2. The impact-resistant enclosure proposed in this utility model involves the following steps when connecting two enclosure bodies: First, a first connecting post is placed into the placement box of one enclosure body. Then, the fixing post of the second connecting post is placed into the inner end of the hollow post. At this time, the second connecting post is placed into the placement box on the opposite side of the other enclosure body. Next, the top cover is placed into the placement box, and the threaded post is screwed into the threaded hole. Since the two connecting blocks are hinged and the fixing post can rotate inside the hollow post, the other enclosure body can remain in the same position when one enclosure body rotates. The connection process of this invention is simple. The combination of threaded post and threaded hole makes the installation and disassembly of the enclosure body more convenient and quick, thereby improving work efficiency and operational convenience.

[0027] 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.
[0028] Reference Figure 1 , Figure 2 , Figure 7 One embodiment provided by this utility model:
[0029] An impact-resistant enclosure includes two enclosure bodies 1 and a connecting mechanism 3. A placement box 2 is fixedly provided on both sides of the two enclosure bodies 1. The two enclosure bodies 1 include two wear-resistant layers 101. A support layer 102 and a buffer layer 103 are respectively provided on the opposite side of the two wear-resistant layers 101. The two wear-resistant layers 101 are made of polycarbonate, the support layer 102 is made of high-density polyethylene, and the buffer layer 103 is made of foamed polypropylene. The two wear-resistant layers 101 are connected to the support layer 102 and the buffer layer 103 by adhesive.
[0030] Specifically, the two outermost wear-resistant layers 101 of the enclosure body 1 are made of polycarbonate, which has good scratch resistance and wear resistance, effectively extending the service life of the enclosure and reducing the frequency of maintenance and replacement. The support layer 102 is made of high-density polyethylene, providing strong support to ensure the enclosure remains stable under stress, reduce deformation, and enhance the overall structural integrity. The buffer layer 103 is made of foamed polypropylene, which can absorb impact force, reduce the impact of external impact on the enclosure and its support structure, and protect the integrity of the enclosure under harsh conditions. The wear-resistant layer 101, support layer 102 and buffer layer 103 are connected by adhesive to improve the bonding strength between the layers, making them form a whole and effectively improving the impact resistance of the enclosure.
[0031] Reference Figures 3-6 The connecting mechanism 3 includes a first connecting post 301, a second connecting post 303, and two top covers 306. A hollow post 302 is fixedly installed on one side of the first connecting post 301, and a fixed post 304 is fixedly installed on one side of the second connecting post 303. Threaded holes 305 are opened at the upper ends of the first connecting post 301 and the second connecting post 303. Threaded posts 307 are threadedly installed at the inner ends of the two top covers 306. Connecting blocks 308 are fixedly installed on opposite sides of the two top covers 306. The first connecting post 301 is placed in the placement box 2 of one of the enclosure body 1, and the second connecting post 303 is placed in the placement box 2 of the other enclosure body 1. The two top covers 306 are placed on the upper ends of the first connecting post 301 and the second connecting post 303. The two threaded posts 307 are respectively threaded at the inner ends of the two threaded holes 305. The two connecting blocks 308 are hinged together. The fixed post 304 is placed at the inner end of the hollow post 302.
[0032] Specifically, when connecting two enclosure body 1, firstly, the first connecting post 301 is placed into the placement box 2 of one enclosure body 1, and then the fixing post 304 of the second connecting post 303 is placed into the inner end of the hollow post 302. At this time, the second connecting post 303 is placed into the placement box 2 on the opposite side of the other enclosure body 1. Next, the top cover 306 is placed into the placement box 2, and the threaded post 307 is screwed into the threaded hole 305. Since the two connecting blocks 308 are hinged, and the fixing post 304 can rotate inside the hollow post 302, when one enclosure body 1 rotates, the other enclosure body 1 can remain in the same position. The connection process of this new type is simple. The combination of the threaded post 307 and the threaded hole 305 makes the installation and disassembly of the enclosure body 1 more convenient and quick, thereby improving work efficiency and operational convenience.
[0033] Working principle: The two outermost wear-resistant layers 101 of the enclosure body 1 are made of polycarbonate, which has good scratch resistance and wear resistance, and can effectively extend the service life of the enclosure. The support layer 102 is made of high-density polyethylene, which provides strong support and ensures that the enclosure remains stable under stress. The buffer layer 103 is made of foamed polypropylene, which can absorb impact. The wear-resistant layer 101, the support layer 102 and the buffer layer 103 are connected by adhesive to improve the bonding strength between the layers.
[0034] Secondly, when connecting the two enclosure bodies 1, firstly, the first connecting post 301 is placed into the placement box 2 of one enclosure body 1, and then the fixing post 304 of the second connecting post 303 is placed into the inner end of the hollow post 302. At this time, the second connecting post 303 is placed into the placement box 2 on the opposite side of the other enclosure body 1. Then, the top cover 306 is placed into the placement box 2, and the threaded post 307 is screwed into the threaded hole 305. Since the two connecting blocks 308 are connected by a hinge, and the fixing post 304 can rotate inside the hollow post 302, when one enclosure body 1 rotates, the other enclosure body 1 can keep its position unchanged.
[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
