DETAILED DESCRIPTION​

[0031] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0032] like Figures 1 to 5 As shown in the figure, a folding wire mesh cage of this utility model includes a base frame 10, a folding frame 20, and stacking feet 30. The base frame 10 is provided with support seats 11 at each of its four corners. The folding frame 20 is located on the four sides of the base frame 10 and includes a first folding frame 21 and a second folding frame 22. The first folding frame 21 is located on the left and right sides of the base frame 10 and is provided with a movable connecting mechanism to connect with the support seats 11. The second folding frame 22 is located on the front and rear sides of the base frame 10, and the bottom of the second folding frame 22 is hinged to the support seats 11. The stacking feet 30 are located on the bottom sides of the base frame 10. The stacking feet 30 are provided with anti-friction pads, and the outer edges of the two opposite sides of the stacking feet 30 are provided with rolled edges.

[0033] Implementation, for example Figure 1 As shown, each of the four corners of the base frame 10 is provided with a support base 11 for supporting and connecting the folding frame 20. The folding frame 20 is located on the four sides of the base frame 10, specifically including a first folding frame 21 and a second folding frame 22. The first folding frame 21 is located on the left and right sides of the base frame 10 and is connected to the support base 11 through a movable connecting mechanism. The movable connecting mechanism adopts the form of a pin and a positioning port, which can easily realize the folding and unfolding of the first folding frame 21. The second folding frame 22 is located on the front and rear sides of the base frame 10, and its bottom is hinged to the support base 11 through a hinge mechanism. The hinge mechanism adopts a threaded hole and screw cooperation structure, which allows the second folding frame 22 to rotate more flexibly, thereby facilitating the conversion between folded and unfolded states.

[0034] The stacking feet 30 are fixedly installed on both sides of the bottom of the base frame 10. Their upper surfaces are equipped with anti-friction pads made of rubber to reduce friction loss during the stacking of wire mesh cages and extend the service life of the stacking feet. The outer edges of the two opposite sides of the stacking feet 30 are rolled edges, formed by a stamping process. Since wire mesh cages are generally made of metal, without this rolling edge treatment, there would be safety hazards for operators.

[0035] In this embodiment, when the folding cage is not in use, the folding frame 20 can be folded onto the base frame 10 through the movable connecting mechanism and the hinge mechanism, which occupies little space and is convenient for storage and transportation. When in use, after the folding frame 20 is unfolded, it achieves good load-bearing performance and stacking stability through the joint action of the support base 11 and the stacking feet 30, which is suitable for logistics storage and transportation scenarios.

[0036] Implementation, for exampleFigure 2 and Figure 3 As shown in the figure, preferably, the first folding frame 21 and the second folding frame 22 are both provided with a side frame assembly 200 and an end frame assembly 300; the side frame assembly 200 comprises a side frame 201 and a side plate 202, and the end frame assembly 300 comprises an end frame 301 and a metal woven net 302; the side frame assembly 200 is movably connected to the end frame assembly 300.

[0037] The first folding frame 21 and the second folding frame 22 are both provided with a side frame assembly 200 and an end frame assembly 300, which are used for storing articles and enhancing the structural strength of the folding net cage. The side frame assembly 200 comprises a side frame 201 and a side plate 202, the side frame 201 is a rectangular frame structure made by welding process, and the side plate 202 is made of metal plate material, which can be optionally made of high-strength plastic plate material, and the side plate 202 is fixedly connected to the inside of the side frame 201, which is used to provide lateral support and protection.

[0038] The end frame assembly 300 comprises an end frame 301 and a metal woven net 302, the end frame 301 also adopts a rectangular frame structure and is formed into an integral frame by welding; the metal woven net 302 is fixedly connected to the inside of the end frame 301, and the metal woven net 302 is woven by high-strength steel wire and has good carrying capacity, which is used to protect the articles inside the net cage and at the same time reduce the overall weight.

[0039] The side frame assembly 200 is connected to the end frame assembly 300 through a movable connection mechanism, so that the side frame assembly 200 and the end frame assembly 300 can rotate at a certain angle, thereby facilitating the folding and unfolding of the folding frame. In the folded state, the side frame assembly 200 and the end frame assembly 300 can be tightly folded onto the chassis 10, reducing the space occupied by the net cage; in the unfolded state, the side frame assembly 200 and the end frame assembly 300 jointly form a complete side frame and end frame structure, effectively protecting the articles inside.

[0040] The embodiment is as shown in the figure Figure 2 Preferably, the movable connection part of the second folding frame 22 is provided with a plurality of fixing rings 23 and connecting pieces 24, the fixing rings 23 are fixedly connected to the lower side of the end frame assembly 300, the connecting pieces 24 are arranged on the fixing rings 23, and one side of the connecting pieces 24 is connected to the side frame assembly 200.

[0041] The movable connection part of the second folding frame 22 is provided with a plurality of fixing rings 23 and connecting pieces 24, which are used to realize the movable connection between the end frame assembly 300 and the side frame assembly 200. The fixing rings 23 are fixedly arranged on the lower side of the end frame assembly 300 and are made of metal material, which are connected to the end frame 301 by welding to ensure their firmness and durability.

[0042] The connecting piece 24 is arranged on the fixed ring 23 in a penetrating manner, and is configured to rotate the end frame assembly 300 and the side frame assembly 200 in a rotatable manner, so that the end frame assembly 300 and the side frame assembly 200 can move flexibly.

[0043] During the use of the foldable net cage, when the second foldable frame 22 is in the unfolded state, the connecting piece 24 can keep the end frame assembly 300 and the side frame assembly 200 connected, and ensure the overall strength and stability of the frame; when the foldable net cage needs to be folded, the end frame assembly 300 and the side frame assembly 200 can be folded onto the base frame 10 along the moving direction of the second foldable frame 22 by rotating the connecting piece 24, so as to reduce the occupied space and facilitate storage and transportation.

[0044] For example, the second foldable frame 22 has a folded state and an initial state. Figure 2 As shown in the drawings, preferably, the second foldable frame 22 has a folded state and an initial state.

[0045] The fixed ring 23 can rotate around the connecting piece 24, so that the end frame assembly 300 can be converted between the folded state and the initial state together with the side frame assembly 200.

[0046] It can be understood that the second foldable frame 22 has a folded state and an initial state, and the end frame assembly 300 can be flexibly converted between the folded state and the initial state together with the side frame assembly 200 through the cooperation of the fixed ring 23 and the connecting piece 24.

[0047] Specifically, the fixed ring 23 is fixedly connected to the upper end of the side frame assembly 200, and the inner diameter of the fixed ring 23 is slightly larger than the diameter of the connecting piece 24, so that the fixed ring 23 can rotate freely on the connecting piece 24. One end of the connecting piece 24 is fixedly connected to the end frame assembly 300 by welding, and the other end penetrates the fixed ring 23 and is hingedly connected to the second foldable frame 22, forming a movable connection structure.

[0048] When the second foldable frame 22 is in the initial state, the fixed ring 23 rotates around the connecting piece 24, so that the end frame assembly 300 and the side frame assembly 200 are unfolded to a predetermined position, forming the side wall and end wall structures of the net cage.

[0049] When the second foldable frame 22 needs to be folded onto the base frame 10, the fixed ring 23 can be rotated around the connecting piece 24 by manual or mechanical auxiliary operation, so as to gradually move the end frame assembly 300 and the side frame assembly 200 closer to each other and fold them onto the base frame 10.

[0050] For example, the second foldable frame 22 has a folded state and an initial state. Figure 4As shown, preferably, the top of the support base 11 is provided with a positioning opening 12, and the two side edges of the first folding frame 21 are provided with outwardly protruding insertion pins 13; the insertion pins 13 of the first folding frame 21 can cooperate with the positioning opening 12 of the support base 11, for fixing the unfolded state of the first folding frame 21, and the folding of the first folding frame 21 can be realized by disengaging the insertion pins 13 from the positioning opening 12.

[0051] It can be understood that the top of the support base 11 is provided with a positioning opening 12, which is used for cooperating with the insertion pins 13 of the first folding frame 21 to realize the unfolding fixing and folding conversion of the first folding frame 21.

[0052] Specifically, the support base 11 is optionally installed at the four corner positions of the chassis 10 by welding or bolt fixing, and the top thereof is machined with a positioning opening 12. The positioning opening 12 is a rectangular or oval opening structure, and the size thereof is designed to match the outer diameter of the insertion pin 13, so as to ensure that the insertion pin 13 can be inserted and clamped. The two side edges of the first folding frame 21 are respectively provided with outwardly protruding insertion pins 13, which are fixed to the frame part of the first folding frame 21 by welding.

[0053] In use,

[0054] When the net cage is unfolded for use, the first folding frame 21 is unfolded to a predetermined position by manual operation, the insertion pins 13 are aligned and inserted into the positioning opening 12 at the top of the support base 11, and the insertion pins 13 can more effectively fix the unfolded state of the first folding frame 21 after being clamped with the positioning opening 12.

[0055] When the first folding frame 21 needs to be folded, the insertion pins 13 are lifted from the positioning opening 12 by appropriate external force, and the first folding frame 21 can be folded onto the chassis 10 along the hinge direction of the movable connection mechanism. The whole process is simple and fast, and no additional tools are needed.

[0056] For example, Figure 1 As shown, preferably, the two side edges of the first folding frame 21 are provided with insertion parts 25 at the end portions thereof; the upper end of the second folding frame 22 is provided with insertion pin locks 26 at the two sides thereof, and the insertion pin locks 26 include insertion rods capable of sliding and rotating; the insertion pin locks 26 cooperate with the insertion parts 25 through the insertion rods, for fixing the second folding frame 22; the insertion pin locks 26 can be disengaged from the insertion parts 25 by sliding and rotating the insertion rods, so that the second folding frame 22 can be unfolded or folded.

[0057] The first folding frame 21 and the second folding frame 22 are connected through the insertion part 25 and the latch 26 for fixing the second folding frame 22. Specifically, the two side end portions of the first folding frame 21 are each provided with an insertion part 25, which is a rectangular slot or a circular hole structure. The insertion part 25 is fixed on the frame of the first folding frame 21 by welding. The upper end of the second folding frame 22 is provided with a latch 26 on each side, which is composed of a plug rod and a locking sleeve. The plug rod can slide along the guide rail of the locking sleeve and rotate within a certain angle range to realize insertion and disengagement operations.

[0058] During the use of the net cage, when the second folding frame 22 needs to be fixed in the unfolded state, the operator slides the plug rod of the latch 26 to the position of the insertion part 25 and inserts the plug rod into the insertion part 25 through a rotating action. When the second folding frame 22 needs to be folded, the operator manually operates the latch 26 to slide and rotate the plug rod to disengage it from the insertion part 25, and then the second folding frame 22 can be folded along the hinge direction onto the base frame 10.
