Description

Technical Field

[0001] The utility model relates to the technical field of cages, in particular to a pet cage. Background Art

[0002] Some existing pet cages are integral structures, consisting of two upper and lower decks and four surrounding side panels welded together. These structures are difficult to disassemble and assemble, making them inconvenient to store and transport. Other pet cages, to facilitate transport and storage, use steel bars and sheet metal for the decks and side panels. The steel bars are then connected using existing clips or connectors to secure them together, allowing the entire cage to be assembled. For example, Chinese patent application number 201220685590.2 discloses a side mesh panel connector for a pet cage that secures two adjacent side mesh panels. However, this connector fails to support the decks, and the side panels connected using this connector have been found to have poor stability and strength, which can easily cause the side mesh panels to loosen, resulting in poor stability for the entire pet cage. Utility Model Content

[0003] In order to solve the deficiencies in the prior art, a pet cage is provided which is easy to transport and assemble and disassemble and has good stability and strength.

[0004] The utility model is implemented by the following technical solution: a pet cage, comprising layer plates spaced apart from each other in an upper and lower direction and side plates located between the layer plates and enclosing a cage body, wherein opposite sides of the two layer plates are provided with snap-fitting grooves for fixing the upper and lower ends of the side plates, the side plates comprising frame ribs and sheets covering the frame ribs or grid ribs filling between the frame ribs, vertically extending support columns are provided between adjacent side plates, and the upper and lower ends of the support columns abut against the layer plates; both horizontal sides of the support columns are provided with a plurality of side plate fixing portions extending toward the adjacent side plates, the side plate fixing portions are provided with snap-fitting holes, and the frame ribs are confined within the snap-fitting holes.

[0005] This solution uses the layer panels to secure the upper and lower edges of the side panels, securing the side panels to the layer panels. The position of the side panels is restricted by the layer panels. The frame ribs are secured to the side panel fixing portions on the support columns through the snap-in holes. The horizontal edges of the side panels are secured by the support columns, further restricting their position. Compared to the reference document, the side panels of this solution are more stable. The support columns also provide abutment support against the layer panels, improving their load-bearing capacity and overall stability. Furthermore, this solution is simple to install, making it easier for users to disassemble, assemble, and transport the pet cage.

[0006] The sheet material can be an existing magic sheet or a hard plate fixed to the frame rib by snapping.

[0007] Among them, how to limit the frame reinforcement by the clamping hole can be achieved by using a C-shaped hole to elastically clamp the frame reinforcement or by using a closed and detachable side panel fixing part to disassemble and assemble the clamping hole and enclose the frame reinforcement.

[0008] The frame reinforcement is any existing frame material used for pet cages, such as steel bars or hard plastic with high strength.

[0009] Among them, the side panels are the front, back, left and right panels of the pet cage.

[0010] The upper and lower ends of the support column abut against the layer plate, which can be the end surface of the support column abutting against the end surface of the layer plate, or the layer plate can be provided with a slot hole, and the support column is inserted into the slot hole for abutment.

[0011] Preferably, the upper and lower ends of the support column are provided with vertically extending clamping parts, and the layer plate is provided with matching grooves adapted to the clamping parts.

[0012] The cooperation between the matching grooves of the layer plates and the clamping parts at both ends of the support column further improves the stability of the layer plates and increases the strength of the entire pet cage.

[0013] Preferably, the support column is an integrated structure, the opening of the clamping hole of the side panel fixing portion is C-shaped and the opening of the clamping hole can be elastically contracted, and the width of the clamping hole opening is smaller than the width of the frame rib.

[0014] The frame rib is clamped into the clamping hole by deforming the opening of the clamping hole.

[0015] Preferably, the support column is a split structure, and the support column includes a first mounting plate and a second mounting plate separated along the vertical direction, and the side plate fixing portion includes a first clamping portion and a second clamping portion respectively arranged on the first mounting plate and the second mounting plate, and the first clamping portion and the second clamping portion are both provided with relatively open notches; when the first mounting plate and the second mounting plate are fixed, the notches of the first clamping portion and the second clamping portion enclose to form the closed clamping hole.

[0016] By splicing and fixing the first mounting plate and the second mounting plate, the first clamping portion and the second clamping portion notch enclose the closed clamping hole. The closed clamping hole restricts the position of the frame rib, and this restriction method can completely prevent the frame rib from escaping from the clamping hole. The first mounting plate and the second mounting plate can be fixed by a snap fit, or by a connecting pin, etc.

[0017] Preferably, a positioning groove and a positioning convex edge extending into the positioning groove are provided between the first mounting plate and the second mounting plate. The positioning convex edge and the positioning groove both extend in the vertical direction, and the edge of the positioning convex edge close to the positioning groove is chamfered.

[0018] The positioning groove and the positioning flange cooperate, and both the positioning flange and the positioning groove extend in the vertical direction to adjust the horizontal position between the first mounting plate and the second mounting plate. The chamfered structure allows the positioning flange to have a guiding effect when inserted into the positioning groove, facilitating the cooperation between the first mounting plate and the second mounting plate.

[0019] Preferably, the clamping parts are provided at the upper and lower ends of the second mounting plate, and the upper and lower ends of the first mounting plate are clamped between the two clamping parts.

[0020] The clamping portion is provided on the second mounting plate. The clamping portion is a single piece rather than a spliced ​​structure, making it easy to insert into the matching groove of the layer plate. At the same time, a space is formed between the two clamping portions to allow the first mounting plate to be spliced ​​with the second mounting plate, thereby locating the upper and lower positions of the first mounting plate.

[0021] Preferably, an elastic pin lock is provided in the clamping part, and the elastic pin lock includes a protrusion and an elastic member. The protrusion can elastically expand and contract under the action of the elastic member. A avoidance hole for the protrusion to move is provided on the side wall of the clamping part. In a natural state, the protrusion protrudes from the avoidance hole, and when subjected to force, the protrusion retracts through the avoidance hole; a socket that cooperates with the protrusion is provided on the groove wall of the mating groove; when the clamping part is inserted into the mating groove, the protrusion is inserted into the socket.

[0022] The plug-in fit between the protrusion and the socket makes it difficult for the clamping portion and the fitting groove to move up and down, so that the fixation between the support column and the layer plate is more secure, thereby increasing the stability and strength of the pet cage.

[0023] Preferably, the upper and lower ends of the first mounting plate are provided with accommodating grooves open to the second mounting plate side, and the accommodating groove is provided with a vertically extending elastic pin lock, and the elastic pin lock includes a spring piece and a protrusion installed at one end of the spring piece, and the end of the spring piece away from the protrusion is located at the bottom of the accommodating groove, and one end of the spring piece mounting protrusion protrudes out of the end of the first mounting plate; the end of the second mounting plate is provided with a fixing protrusion corresponding to the accommodating groove, and the groove wall of the matching groove is provided with a socket corresponding to the protrusion, and the clamping part is provided with an avoidance groove for avoiding the spring piece and the protrusion; when the first mounting plate and the second mounting plate are spliced, the fixing protrusion presses the spring piece against the groove wall of the accommodating groove, and when the clamping part is plugged into the matching groove, the protrusion extends into the socket under the action of the spring piece.

[0024] The spring piece is pressed by the fixing protrusion so that the position of the spring piece is fixed. Thereafter, when the clamping part is plugged into the matching groove, the spring piece and the protrusion will be squeezed by the groove wall of the matching groove, so that the spring piece and the protrusion will be located in the avoidance groove, so that the clamping part can smoothly enter the matching groove. When the protrusion encounters the insertion hole, the protrusion is directly inserted into the insertion hole under the action of the spring piece, so that the layer plate and the support column cannot move upward, thereby further improving the strength of the pet cage.

[0025] Preferably, the first mounting plate and the second mounting plate are respectively provided with a plurality of first fixing holes and second fixing holes corresponding to each other at vertical positions, and the first fixing holes and the second fixing holes are connected by fixing members.

[0026] The first mounting plate and the second mounting plate are fixed after being spliced ​​together by passing the fixing piece through the first fixing hole and the second fixing hole, wherein the fixing piece may be a connecting pin, an expansion pin, etc.

[0027] Preferably, the layer plate is a split structure, comprising a supporting frame and a supporting plate arranged on the supporting frame, and the supporting frame is provided with the snap-fitting groove and the matching groove.

[0028] The split structure is easy to disassemble and replace, and has better versatility. The load-bearing plate can be a mesh structure, a solid plate structure, or a plate structure with a door that allows pets to pass through.

[0029] Compared with the prior art, the utility model has the advantages of being easy to transport and assemble and disassemble, and having good stability and strength. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0043] like Figure 1 and Figure 2 As shown, this embodiment discloses a pet cage comprising multiple pet storage layers. Each pet storage layer comprises a layer 1 for supporting the animal and four side panels 2 surrounding the layer 1. The two layer panels 1 and the four side panels 2 form a rectangular space. In this embodiment, the front side panels are composed of two sheet materials, and the rear side panels are composed of two frame panels with grid ribs.

[0044] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 11As shown, the deck 1 comprises a rectangular support frame 11 and a support plate 12. The support plate 12 is detachable from the support frame 11. The support plate 12 can be a mesh structure, a solid plate structure, or a plate structure with a pet-accessible door. In this embodiment, a solid plate structure is used. The side panels 2 comprise frame ribs 23 and sheet materials. The sheet materials can be a first sheet 21 with a mesh structure and a second sheet 22 with a solid plate structure. The first and second sheets 21, 22 both cover and secure the frame ribs 23, which are rectangular and made of steel. The edges of the support frame 11 are provided with upwardly and downwardly opening snap-in slots 31, and the corners of the support frame 11 are provided with upwardly and downwardly opening mating slots 32. The frame ribs 23 snap into the snap-in slots 31. A support column 4 is provided between adjacent side panels 2. The support column 4 has vertically extending snap-in portions 44 at its upper and lower ends. The snap-in portions 44 snap into the mating slots 32 and support the deck 1 above.

[0045] like Figures 4 to 9 As shown, the support column 4 is a split structure, including a first mounting plate 41 and a second mounting plate 42 separated along the vertical direction. Two first clamping portions 411 and a second clamping portion 421 are respectively provided on the horizontal sides of the first mounting plate 41 and the second mounting plate 42, extending toward the side panels 2 on either side. The first clamping portion 411 and the second clamping portion 421 are each provided with a notch opening facing each other. When the first mounting plate 41 and the second mounting plate 42 are spliced ​​together, the first clamping portion 411 and the second clamping portion 421 form the side panel fixing portion 43, and the notches of the two clamping portions 411 and 421 enclose a closed clamping hole 431. The clamping hole 431 is used to clamp the frame reinforcement 23.

[0046] The first mounting plate 41 has a side edge with a vertical positioning flange 414 extending toward the second mounting plate 42. The second mounting plate 42 has a side edge with vertically extending ribs, forming vertically extending positioning grooves 424 between the ribs. The edges of the positioning flange 414 near the positioning grooves 424 are chamfered. When the first and second mounting plates 41 and 42 are fixed, the positioning flange 414 extends into the positioning grooves 424.

[0047] The clamping parts 44 are provided at the upper and lower ends of the second mounting plate 42 . The horizontal width of the clamping parts 44 is greater than the horizontal width of the second mounting plate 42 , so that a space is formed between the two clamping parts 44 so that the first mounting plate 41 and the second mounting plate 42 can be spliced ​​together.

[0048] The first mounting plate 41 is provided with three first fixing holes 412 evenly spaced vertically, and the second mounting plate 42 is provided with second fixing holes 422 evenly spaced vertically and corresponding one-to-one with the first fixing holes 412. When the first mounting plate 41 and the second mounting plate 42 are joined, the first fixing holes 412 and the second fixing holes 422 are secured together by fixing members. The fixing members can be any existing connecting pins that pass through the first fixing holes 412 and the second fixing holes 422 to secure the first mounting plate 41 and the second mounting plate 42.

[0049] like Figure 3 、 Figure 4 and Figure 10 As shown, the clamping portion 44 is provided with an upwardly opening placement slot 46, in which an elastic pin lock is installed. The elasticity includes a protrusion 45 and an elastic member 451. The elastic member 451 is an L-shaped leaf spring, the lower end of which is fixedly connected to the bottom of the placement slot 46. The protrusion 45 can elastically expand and contract under the action of the elastic member 451. The side wall of the clamping portion 44 is provided with a relief hole to allow the protrusion 45 to elastically move; the groove wall of the mating groove 32 is provided with a socket 33 that matches the protrusion 45. When the clamping portion 44 is inserted into the mating groove 32, the protrusion 45 is first compressed into the clamping portion 44. When the relief hole and the socket 33 overlap, the protrusion 45 is inserted into the socket 33, thereby fixing the support column and the shelf.

[0050] During installation, the user first snaps the side panel 2 into the snap-in slot 31 of the shelf 1. Insert the snap-in portion 44 of the second mounting plate 42 into the mating slot 32 of the shelf 1, securing the protrusion 45 within the insertion hole 33. Simultaneously, the frame rib 23 snaps into the notch of the second clamping portion 421. Next, the first and second mounting plates 41 and 42 are joined and secured together using connecting pins, ensuring that the first and second clamping portions 411 and 421 cooperate to restrict the position of the frame rib 23. Finally, the upper shelf 1 is secured to the side panel 2 and support column 4 using the same method as above, completing the pet cage installation.

[0051] Example 2

[0052] The difference between this embodiment 2 and embodiment 1 is that the elastic member 451 is a spring that applies elastic force to the protrusion 45. (Not shown in the figure)

[0053] Example 3

[0054] like Figure 8 and Figure 9As shown, the difference between this embodiment 3 and embodiment 1 is that: the upper and lower ends of the first mounting plate 41 are provided with a receiving groove 413 that is open to the side of the second mounting plate 42, and a vertically extending elastic pin lock (not shown in the figure) is provided in the receiving groove 413. The elastic pin lock includes an L-shaped spring piece and a protrusion installed at one end of the spring piece. The end of the spring piece away from the protrusion is located at the bottom of the groove abutting the receiving groove 413, and the end of the spring piece close to the protrusion protrudes from the end of the first mounting plate 41; the end of the second mounting plate 42 is provided with a fixing protrusion 423 corresponding to the receiving groove 413, and the groove wall of the mating groove 32 is provided with a socket 33 corresponding to the protrusion. The clamping portion 44 is provided with an avoidance groove (not shown in the figure) for avoiding the spring sheet and the protrusion; when the first mounting plate 41 and the second mounting plate 42 are spliced ​​together, the fixed protrusion 423 presses the spring sheet against the groove wall of the accommodating groove, and when the clamping portion 44 is plugged into the matching groove 32, the protrusion extends into the socket 33 under the action of the spring sheet.

[0055] Example 4

[0056] The difference between this embodiment 4 and embodiment 1 is that the support column 4 is an integrated structure, and a number of side panel fixing parts 43 extending toward the side panel 2 are provided on both sides of the support column 4. The side panel fixing parts 43 are provided with snap-in holes 431. The openings of the snap-in holes 431 face the direction in which the frame rib 23 can be snapped in. The snap-in holes 431 are C-shaped and the openings of the snap-in holes 431 can be elastically contracted. The width of the openings of the snap-in holes 431 is smaller than the width of the frame rib 23 (not shown in the figure).
