Description

Technical Field

[0001] This utility model relates to the field of radio frequency identification technology, specifically a multi-fold shielding enclosure. Background Technology

[0002] In manual RFID environments, fixed reading shielding devices are often used for accurate identification of RFID-tagged goods during application, such as RFID gates. However, these devices are limited by the environment; the RFID-tagged goods or pallets to be scanned must be individually removed and placed into the RFID gate or other fixed RFID device for scanning. This method is cumbersome. If the warehouse is large and the RFID gate or other RFID device is located far away, following the usage process of fixed reading shielding devices often increases time and labor costs, resulting in low work efficiency. Reading shielding devices often occupy a large area and cannot be moved freely for identification. Therefore, the current method of manually using the built-in RFID reading module of a handheld device to identify RFID tags is used. However, when manually scanning a box or stack of goods with RFID tags, direct scanning is subject to interference from surrounding goods with RFID tags and stacks. This can lead to missed or multiple RFID tags being scanned, resulting in uncontrollable accuracy of RFID radio frequency identification. Therefore, a shielding device that can directly shield other goods with RFID tags in the warehouse storage area is needed to ensure that manual scanning of a box or stack using a handheld device is not interfered with.

[0003] However, when the existing equipment is needed, it is difficult for people to quickly move the equipment to the designated location and scan one or several boxes of goods with RFID tags in the storage area. After use, it is also difficult to move the equipment away quickly. In addition, the equipment occupies a lot of space, resulting in a large warehouse space occupancy rate. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-fold shielding enclosure. By setting up a frame assembly, a folding frame assembly, a positioning hinge assembly, A shielding cloth and B shielding cloth, it solves the problems of existing equipment, which are difficult to move to the designated location by manpower when needed, scan one or several boxes of goods with RFID tags in the storage area together, and are also difficult to move away quickly after use. In addition, the equipment occupies a large space, resulting in a large warehouse space occupancy rate.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a multi-fold shielding enclosure, including a frame assembly, wherein folding frame assemblies are fixedly connected between the frame assemblies;

[0022] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, this embodiment proposes a multi-fold shielding enclosure, including a frame assembly, with folding frame assemblies fixedly connected between the frame assemblies;

[0025] The frame assembly includes multiple frame columns 1, which are arranged in parallel pairs. The top of each pair of frame columns 1 is fixedly installed with a frame A horizontal column 3 via profile corner fittings 2. The bottom of one pair of frame columns 1 is fixedly installed with a frame B horizontal column 4 via profile corner fittings 2.

[0026] The folding frame assembly includes multiple folding columns 5, and positioning hinge assemblies are fixedly installed between the folding columns 5. Four positioning hinge assemblies are fixedly installed at the upper and lower ends between the two sets of frame columns 1, and three folding columns 5 are rotatably connected to connecting blocks 6 through the positioning hinge assemblies.

[0027] The frame columns 1, A-frame horizontal columns 3, B-frame horizontal columns 4, and folding columns 5 are all made of 4040 aluminum square tubing. One set of frame columns 1, A-frame horizontal columns 3, and B-frame horizontal columns 4 are connected by profile corner fittings 2 to form a rectangular frame, while the other set forms a C-shaped frame. Multiple folding columns 5 are connected to connecting blocks 6 by positioning hinge components to form a foldable "I"-shaped frame. The positioning hinge components at the ends of the "I"-shaped frame are connected at one end to the fixed rectangular frame and at the other end to the C-shaped frame to form an overall frame.

[0028] The positioning hinge assembly includes two connectors 7, with a hinge shaft 8 inserted between the two connectors 7. A damping spring 9 is sleeved on the surface of the hinge shaft 8. Multiple positioning holes are provided on both sides of the connectors 7, and elastic positioning pins 10 are inserted into the interior of the positioning holes.

[0029] The folding of this device is mainly achieved by a positioning hinge assembly, which consists of a connector 7, a damping spring 9, a hinge shaft 8, and an elastic positioning pin 10. The two connectors 7 are connected by the hinge shaft 8, and one end of the damping spring 9 is fixed to one connector 7, and the other end is fixed to the other connector 7. The upper and lower ends of the positioning hinge assembly are respectively equipped with elastic positioning pins 10. When the hinge is at 0° or 90°, the elastic positioning pin 10 and the damping spring 9 work together to maintain a certain rigidity of the entire frame. When the hinge is between 0° and 90°, the damping spring 9 causes the folding column 5 to approach 0° or 90°, thereby causing the entire frame to contract or extend.

[0030] One side of one of the frame columns 1 is connected to a shielding door 11 via a hinge, and a shielding cloth 12 is fixedly connected to one side of the shielding door 11.

[0031] A lifting ring 13 is fixedly connected to the lower surface of the top folding column 5. The B shielding cloth 14 is suspended from the folding column 5 through the lifting ring 13. One side of the bottom folding column 5 is fixed to the B shielding cloth 14 by rivets.

[0032] B shielding cloth 14 is mainly composed of shielding cloth and nylon cloth. After overlapping and sealing the shielding cloth and nylon cloth, the sealing edge is fixed to the two sides and the upper folding column 5 of the C-shaped frame by pressing. The upper and right sealing edge is hoisted to the folding column 5 by the hoisting ring 13. The edge seam of the hoisting and fixing has a certain size of shrinkage elasticity to ensure that the entire shielding cloth does not tear after deformation after folding. The top surface is mainly to prevent electromagnetic waves from scattering out from the top and affecting the accuracy of reading through reflection from the roof.

[0033] Both the frame column 1 and the lower surface of the shielding door 11 are fixedly connected with universal ball wheels 15.

[0034] Specifically, when using this multi-fold shielding barrier: First, determine the location of the RFID-tagged goods in the warehouse that need to be scanned; second, move the folded shielding barrier to the side of the RFID-tagged goods to be scanned, unfold the shielding barrier, push the RFID-tagged goods into the barrier, close the shielding door 11, and maintain the shielding performance of the equipment through shielding cloth A 12 and shielding cloth B 14; then, manually scan and read the RFID-tagged goods. After scanning, open the shielding door 11, fold the shielding barrier up in sequence, and finally, move the shielding barrier to the designated location.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
