Description

Technical Field

[0001] This utility model belongs to the field of pet carrier technology, and specifically relates to pet carrier expansion and capacity-enhancing folding enclosures. Background Technology

[0002] Pet carriers are portable containers designed to make it easier for owners to carry their pets when traveling. They are mainly used for short trips, such as daily walks, veterinary visits, and short trips. They are designed with mesh, transparent windows, or ventilation holes to balance breathability and visibility.

[0003] In the current technology, pet carriers on the market generally have the problem of fixed internal space and lack of flexibility in design, making it difficult to adapt to the dynamic needs of pets for activity space during transportation, as well as the different requirements of owners for carrier capacity in different scenarios.

[0004] Most existing pet carriers have a fixed volume structure. When pets need to turn around, adjust their posture, or stay in the carrier for a long time, they will feel obvious spatial pressure and discomfort. Although some products attempt to expand the capacity through simple folding structures, the unfolded enclosure often lacks stable support, the material is soft and collapses, and it is easy to deform when pets lean on it, failing to provide a safe and reliable space for pets to move around.

[0005] Furthermore, traditional expansion methods are often cumbersome, requiring the disassembly of multiple connectors and even the use of tools, making them unsuitable for quick responses when space expansion is urgently needed. More importantly, the expanded bag opening often suffers from issues such as incomplete closure and unreliable locking, posing safety hazards such as pets accidentally escaping or foreign objects falling in.

[0006] Meanwhile, existing products, after being expanded, typically lack corresponding extended support structures at the bottom. This results in the expanded bottom area being unsupported or lacking sufficient support, causing pets to feel a sinking sensation when stepping in, which not only makes the pets nervous but also affects the stability of the bag and its overall lifespan. Utility Model Content

[0007] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a pet carrier expansion and capacity-enhancing folding enclosure.

[0008] To achieve the above objectives, this utility model adopts the following technical solution: a pet carrier expansion and capacity-enhancing folding barrier, including a multi-fold barrier, which is fixed to the inner wall of the pet carrier body. The pet carrier body includes a zipper module and multiple ventilation holes. The zipper module includes a fixed chain and a moving chain. One end of the multi-fold barrier is fixed to the inner wall of the pet carrier body, and the multi-fold barrier is folded. The other end of the multi-fold barrier is attached to the inner wall of the pet carrier body. Multiple ventilation holes are provided through the surface of the multi-fold barrier at the corresponding locations of the ventilation holes of the pet carrier body. A bottom plate is provided on one side of the surface of the pet carrier body. Both ends of the moving chain are fixed to one side of the bottom plate, and one end of the fixed chain is fixed to the bottom plate. A release groove is provided at one end of the fixed chain. A bottom support plate is fixed to the inner wall of the pet carrier body at the corresponding location of the bottom plate. The bottom plate is fixed to the bottom support plate by bolts passing through the pet carrier body.

[0009] Preferably, the folds of the multi-fold enclosure are covered with nylon adhesive strips, and a fixed chain is attached to the end of the multi-fold enclosure that is attached to the inner wall of the pet carrier.

[0010] Preferably, a side pad is fixed to the side of the multi-fold enclosure near the moving chain, and nylon adhesive strips are sewn on both sides of the side pad; the side pad is attached to the inner wall of the pet carrier body on the side of the moving chain, and nylon adhesive strips are sewn at the joint between the inner wall of the pet carrier body and the side pad.

[0011] Preferably, a limiting groove is provided on the inner wall of the bottom support plate, and a wing plate is slidably connected to the inner wall of the limiting groove. Multiple wing plates are fixed to a moving extension plate on opposite sides.

[0012] Preferably, one end of the bottom support plate has an end groove, and the inner wall of the end groove is in contact with the vertical end surface of the moving extension plate.

[0013] Preferably, an abutment block is fixed on the side of the wing plate near the moving extension plate; a limiting block is fixed on one end of the inner wall of the limiting groove.

[0014] Preferably, the bottom support plate has multiple arc grooves on the side near the moving plate, and spring arc sheets are nested in the inner wall of the arc grooves. Both ends of the spring arc sheets are fixed to the side of the moving plate near the bottom support plate.

[0015] Preferably, the bottom support plate has an auxiliary groove near the embedded arc groove, and the edges of the embedded arc grooves facing each other are set as guide arc surfaces.

[0016] In summary, this utility model has the following beneficial effects:

[0017] 1. This utility model features a multi-folded enclosure on the inner wall of the pet carrier, with ventilation holes corresponding to the main body of the carrier. This design ensures breathability while creating a quickly expandable space. This structure allows the pet carrier to expand rapidly when needed, providing pets with more room to move around, adjust their posture, and other needs, effectively alleviating the spatial pressure and discomfort caused by a fixed-volume structure.

[0018] 2. This utility model ensures the stability of the multi-folded enclosure when it is not unfolded by covering the folded joints with nylon adhesive sheets, and using side pads and sewn nylon adhesive sheets. This allows the multi-folded enclosure to fit tightly together when stored and fits tightly against the inner wall of the pet carrier body, effectively resisting the pressure of the pet, preventing it from collapsing and deforming, and preventing the ventilation holes from being blocked.

[0019] 3. This utility model has a bottom extension structure composed of a bottom support plate, a sliding wing plate and a moving extension plate, and a limiting block and abutment block are set in the bottom support plate to provide solid mechanical support for the extended bottom area, prevent the bottom from sinking, enhance the stability and support of the overall structure, and ensure the safety of pets.

[0020] 4. This utility model, through the specific fixing method of the fixed chain and the moving chain in the zipper module, and the release groove opened at one end of the fixed chain, allows the user to quickly detach the zipper head from one end of the fixed chain through the release groove, while the zipper head remains on the moving chain and can quickly engage with the fixed chain at one end of the multi-fold enclosure, simplifying the expansion operation steps and achieving rapid response.

[0021] 5. This utility model uses a bottom spring arc plate to fix the two ends of the bottom support plate and the moving extension plate respectively, and nests them in the arc groove. The elastic deformation of the spring arc plate assists the smooth extension and retraction of the moving extension plate, which further improves the ease of operation. Attached Figure Description

[0042] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0043] The specific embodiments of this utility model are described below with reference to the accompanying drawings:

[0044] Example 1:

[0045] refer to Figures 1-10The pet carrier features an expandable and foldable enclosure, including a multi-fold enclosure 3. The multi-fold enclosure 3 is fixed to the inner wall of the pet carrier body 1. The pet carrier body 1 includes a zipper module 101 and multiple ventilation holes 104. The zipper module 101 includes a fixed chain 102 and a moving chain 103. One end of the multi-fold enclosure 3 is fixed to the inner wall of the pet carrier body 1, and the multi-fold enclosure 3 is folded. The other end of the multi-fold enclosure 3 is flush with the inner wall of the pet carrier body 1. Multiple ventilation holes 104 are provided through the surface of the multi-fold enclosure 3 at the corresponding locations of the ventilation holes 104 of the pet carrier body 1. A bottom plate 2 is provided on one side of the surface of the pet carrier body 1. Both ends of the moving chain 103 are fixed to one side of the bottom plate 2. One end of the fixed chain 102 is fixed to the bottom plate 2, and a release groove 201 is provided at one end of the fixed chain 102. A bottom support plate 6 is fixed to the inner wall of the pet carrier body 1 at the corresponding location of the bottom plate 2. The bottom plate 2 is fixed to the bottom support plate 6 by bolts passing through the pet carrier body 1.

[0046] Specifically, by fixing one end of the multi-fold enclosure 3 to the inner wall of the pet carrier body 1 and folding it, and attaching the other end to the inner wall of the pet carrier body 1 through the nylon adhesive sheet 4 of the side pad 5, and opening ventilation holes 104 on its surface corresponding to the pet carrier body 1, an expansion space that can be quickly unfolded is constructed, ensuring ventilation before and after expansion. The bottom plate 2 is fixedly connected to the bottom support plate 6 with bolts, providing a stable installation base for the entire expansion structure, and allowing the bottom plate 2 to be quickly disassembled, thereby disengaging the moving chain 103 from the fixed chain 102.

[0047] The folded enclosure 3 is covered with nylon adhesive strips 4 at the folding and sticking points, and a fixed chain 102 is fixed to the end of the multi-fold enclosure 3 that is attached to the inner wall of the pet carrier body 1.

[0048] A side pad 5 is fixed to the side of the multi-folded enclosure 3 near the moving chain 103, and nylon adhesive strips 4 are sewn on both sides of the side pad 5; the side of the side pad 5 near the moving chain 103 is attached to the inner wall of the pet carrier body 1, and nylon adhesive strips 4 are sewn at the joint between the inner wall of the pet carrier body 1 and the side pad 5.

[0049] Specifically, by covering the folded joints of the multi-folded enclosure 3 with nylon adhesive strips 4 and fixing a chain 102 at the end that adheres to the inner wall of the pet carrier body 1; at the same time, side pads 5 are provided and nylon adhesive strips 4 are sewn on both sides and at corresponding locations on the inner wall of the pet carrier body 1. The adhesive effect of the nylon adhesive strips 4 ensures that the multi-folded enclosure 3 can fit tightly against itself and the inner wall of the pet carrier body 1 when it is folded up, effectively preventing accidental deformation caused by its own softness or pressure from the pet or the obstruction of the ventilation holes 104.

[0050] The inner wall of the bottom support plate 6 is provided with a limiting groove 702, and a wing plate 701 is slidably connected to the inner wall of the limiting groove 702. Multiple wing plates 701 are fixed to one side of each other with a moving extension plate 7.

[0051] One end of the bottom support plate 6 is provided with an end groove 703, and the inner wall of the end groove 703 is in contact with the vertical end surface of the moving extension plate 7.

[0052] An abutment block 801 is fixed to one side of the wing plate 701 near the moving extension plate 7; a limiting block 8 is fixed to one end of the inner wall of the limiting groove 702.

[0053] Specifically, a limiting groove 702 is formed in the inner wall of the bottom support plate 6, which together with the wing plate 701 slidably connected therein and the moving extension plate 7 fixed to the opposite side of the multiple wing plates 701, forms the bottom extension structure. The end groove 703 is guided by its contact with the vertical end surface of the moving extension plate 7, and the sliding stroke of the moving extension plate 7 is limited by the cooperation between the abutment block 801 fixed on the wing plate 701 and the limiting block 8 fixed in the inner wall of the limiting groove 702. This provides solid mechanical support and safety limit for the extended bottom area, avoiding stability problems caused by insufficient support or excessive extension of the extended area.

[0054] The bottom support plate 6 has multiple embedded arc grooves 903 on the side near the moving extension plate 7. Spring arc pieces 9 are nested in the inner wall of the embedded arc grooves 903. Both ends of the spring arc pieces 9 are fixed to the side of the moving extension plate 7 near the bottom support plate 6.

[0055] An auxiliary groove 901 is provided on the bottom support plate 6 near the embedded arc groove 903, and the mutually facing edges of the embedded arc groove 903 are set as guide arc surfaces 902.

[0056] Specifically, by creating an embedded arc groove 903 on the bottom support plate 6 and nesting a spring arc plate 9 within it, with both ends of the spring arc plate 9 fixed to the moving extension plate 7, the elastic deformation of the spring arc plate 9 provides temporary fixation when the moving extension plate 7 extends or retracts, preventing the moving extension plate 7 from sliding due to the pet's movement. By creating an auxiliary groove 901 and designating the mutually facing edges of the embedded arc groove 903 as guide arc surfaces 902, the movement trajectory and deformation space of the spring arc plate 9 are further optimized, improving the smoothness and reliability of operation.

[0057] Example 2:

[0058] refer to Figures 1-10 Staff members used the structure disclosed in this utility model in a pet hospital;

[0059] The veterinarian is using a pet carrier equipped with an expandable folding bib. The carrier is made of 1680D double-strand nylon fabric, with basic dimensions of 50 cm long, 40 cm wide, and 45 cm high. It features evenly distributed 10 mm diameter ventilation holes on the sides. When a 25 kg Golden Retriever appeared cramped inside, the owner activated the expansion function.

[0060] First, unfasten the four sets of nylon adhesive tabs on the side to separate the folded multi-panel bumper from the inner wall of the bag. The multi-panel bumper is made of five layers of high-strength Oxford cloth, ultrasonically welded together, with each layer being 2 mm thick, resulting in a total thickness of only 12 mm when folded. Next, slide the YKK No. 5 zipper pull out of the release slot at the end of the fixed chain and remove the M6 ​​stainless steel bolts at the four corners of the bottom plate, dividing the bag into upper and lower sections. After engaging the zipper pull with the starting end of the fixed chain at the free end of the multi-panel bumper, pull the zipper upwards. The side panel expansion is completed in just 15 seconds, increasing the effective volume of the pet bag from 90 liters to 150 liters.

[0061] The expanded multi-fold enclosure creates a 30cm high three-dimensional space, with 256 ventilation holes on its surface perfectly aligned with the original ventilation holes in the main body to maintain airflow. Simultaneously, pulling the bottom extension plate outwards causes two 18cm wide ABS engineering plastic wing plates to slide smoothly out within the limiting groove. Spring-loaded plates elastically deform within the recessed grooves, providing continuous support. When the extension plate extends to 25cm, the nylon contact blocks on the wing plates make tight contact with the polyurethane limiting blocks within the limiting groove, forming a mechanical limit. Load-bearing tests at the expanded bottom show that the extension plate can evenly bear a weight of 30kg without significant deformation.

[0062] During the two-hour waiting period, the Golden Retriever could freely turn and adjust its posture within the extended space, and the temperature inside the carrier remained below 28 degrees Celsius. When the appointment was over, the owner completed the packing process in just 3 minutes: first, the extended plate was pushed back to the bottom support plate, and the spring-loaded flaps smoothly returned to their original position under the guidance of the curved surface; then, the multi-folded surround was folded and secured back to the inner wall of the carrier with nylon adhesive tape; finally, the bottom plate bolts were reinstalled, restoring the carrier to its compact state. This design successfully solves the problem of space compression for large pets during transportation while maintaining portability, and the extended structure remained fully functional after 200 cycle tests.

[0063] The working principle of this utility model:

[0064] Step 1: When expansion of capacity is needed, first unlock the multi-fold guardrail 3 from its folded state. When folded, the multi-fold guardrail 3 is bonded to the inner wall of the pet carrier body 1 by the nylon adhesive tabs 4 at its folds and on the side padding fabric 5. The user only needs to apply an outward pulling force to overcome the adhesive force of the nylon adhesive tabs 4, allowing the multi-fold guardrail 3 to separate from the inner wall of the carrier, preparing it for unfolding.

[0065] The zipper head of the zipper module 101 is slid out from its original position through the release groove 201 at the end of the fixed chain 102. Since the moving chain 103 is always fixed to the pet carrier body 1, the zipper head will remain on the moving chain 103. Then, the user removes the bolts from the base plate 2, and the pet carrier body 1 is divided into two parts by the zipper module 101. Then, the zipper head is engaged with the starting end of another fixed chain 102 that is already fixed to the free end of the multi-fold enclosure 3.

[0066] Step 2: By pulling the zipper head, the zipper closes along the fixed chain 102 on the multi-fold enclosure 3 and the moving chain 103 fixed on the base plate 2. After the zipper is fully closed, the multi-fold enclosure 3 transforms from a flat structure that fits tightly against the inner wall of the bag into a three-dimensional extended enclosure that surrounds the original bag opening, thereby significantly increasing the pet's lateral movement space.

[0067] Throughout the entire process, whether in the folded or unfolded state, the corresponding ventilation holes 104 on the multi-fold enclosure 3 and the main body of the pet carrier 1 remain aligned and unobstructed, ensuring air circulation within the expanded space.

[0068] Step 3: After the lateral multi-fold enclosure 3 is pushed out, the user pulls the moving extension plate 7 outward from the bottom support plate 6. The moving extension plate 7 slides smoothly within the limiting groove 702 via its two side wing plates 701, ensuring the stability and straightness of the extension process.

[0069] During the process of pulling out the moving plate 7, the spring arc plate 9 fixed in the arc groove 903 undergoes elastic deformation. The nesting of the arc groove 903 and the spring arc plate 9, as well as the replacement of the spring arc plate 9 with the arc groove 903, helps the moving plate 7 to remain in the extended position, providing initial positioning and preventing it from easily retracting during pet activity.

[0070] When the moving plate 7 slides to its maximum design stroke, the abutment block 801 on its wing plate 701 will come into close contact with the limiting block 8 in the limiting groove 702, forming a robust mechanical hard limit, and the nesting of the arc groove 903 and the spring arc plate 9 will assist in the fixation. This prevents the moving plate 7 from over-extending or collapsing during use, and provides solid and reliable load-bearing support for the extended bottom area.

[0071] Ultimately, the extended plate 7 and the original bottom support plate 6 together form a complete bottom platform, providing uniform support for the entire expanded new space and preventing pets from feeling like they are sinking when they step in.

[0072] Step 4: When the user is finished using the product, slide the zipper head to the release groove 201 at the end of the fixed chain 102 of the multi-fold barrier 3 to disengage the zipper head. Then manually push the moving extension plate 7 back into the bottom support plate 6. The design of the guide arc surface 902 and the auxiliary groove 901 ensures that the spring arc plate 9 can be smoothly compressed, allowing the moving extension plate 7 to return to its original position smoothly.

[0073] Refold the unfolded multi-folded flap 3 and, using its own body and the nylon adhesive strips 4 on the side padding 5, make it fit tightly against the inner wall of the pet carrier body 1, restoring it to a compact, folded state. Finally, re-engage the zipper pull with the fixed zipper 102 in its original position to close the main bag opening.
