Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cage technology, specifically relating to a birdcage door that is easy to open and close. Background Technology
[0002] With socio-economic development and accelerated urbanization, urban households are facing increasing challenges related to independence, individuality, and population aging. Residents' leisure, consumption, and emotional needs are also becoming more diversified. Consequently, more and more families are choosing to keep pets, leading to increased spending on pets and even the perception that pets are important members of the family. Pet cages, as essential entertainment and resting places for pets, mainly consist of a cage body and a cage door, which users open and close using a lock.
[0003] However, traditional door locks on the market require a key or additional tools to open and close the cage door each time, making the operation cumbersome, especially when frequent opening and closing is needed (such as feeding the pet or cleaning the cage), lacking convenience. Utility Model Content
[0004] This utility model discloses a birdcage door structure that is easy to open and close, mainly to solve the problem that the opening and closing of traditional cage doors is not convenient.
[0005] To achieve the aforementioned objective, this utility model provides a birdcage door structure that is easy to open and close, comprising a cage door body. The cage door body is composed of several intersecting and interconnected forming strips and support strips. One side of the cage door body has at least one opening, and a first movable door is provided at the opening. One end of the first movable door is movably connected to the cage door body, and the other end of the first movable door is provided with a mounting part. The mounting part is provided with a hook structure. The first movable door and the cage door body are detachably connected by the hook structure. Both the cage door body and the movable door are formed by forming strips and support strips, and are integrally formed by bending, connecting and other methods. The number of parts is small (no precision lock cylinder, gears and other complex components). The mechanical principle directly relies on the engagement of the hook and support strips and the guidance of the limiting structure. There are few wear points, and it is not easy to fail due to structural failure after long-term use.
[0006] The added limiting structure (such as the limiting ring sleeved on the outside of the support bar / forming bar, and the guiding function of the limiting part) can provide a stable sliding / rotation trajectory for the movable door, avoid jamming, deviation or shaking when opening and closing, ensure that the movable door always moves along a fixed path, and enhance the sealing performance after closing (preventing birds from crawling out).
[0007] Preferably, the forming strip is bent on one side of the cage door body to form a limiting buckle, and the first movable door is movably installed inside the buckle.
[0008] Preferably, the mounting portion of the first movable door forms a hook by bending a strip. The hook closes the opening by engaging with the support strip. The "tight engagement" between the hook and the support strip is the core anti-detachment guarantee. When closed, the hook is naturally locked, and birds cannot pry or knock it open on their own. The limiting ring, limiting part and other structures ensure accurate alignment when the movable door is closed by "fitting" and "guiding", avoiding gaps caused by misalignment and further reducing the possibility of birds crawling out.
[0009] The "movable connection" between the movable door and the cage door body (such as one end fixed and the other end snap-locked) takes into account both the flexibility of opening and closing and the stability of closing, preventing the movable door from falling off accidentally.
[0010] Preferably, the first movable door is provided with limiting structures on both sides, and the limiting structure includes a limiting ring formed by a support bar, the limiting ring being movably sleeved on the outside of the support bar located on both sides of the opening.
[0011] Preferably, the cage door body also has a food box opening, and a second movable door is provided at the food box opening. The second movable door consists of two horizontally arranged support bars and several vertically arranged forming bars. The top and bottom of the second movable door are symmetrically provided with limiting parts, and the two sides of the limiting parts form limiting rings through the support bars. This separate design of the "first movable door (main cage door)" and the "second movable door (dedicated to the food box opening)" achieves functional zoning: the main cage door is used for birds to enter and exit and for operations within the cage, while the food box opening movable door is only used for adding food / changing water. The two open and close independently without interfering with each other. This design avoids the risk of birds being startled or escaping due to frequent opening and closing of the main cage door, and can precisely meet specific needs (such as not needing to open the main cage door when feeding alone), making it more practical.
[0012] Preferably, the limiting ring is movably sleeved on the outside of the forming strips on both sides of the food box opening, and the middle of the second movable door is also formed with a limiting protrusion through the forming strip.
[0013] More preferably, the top and bottom of the first movable door are provided with support bars, and the two sides of the support bars form limiting rings, which are movably sleeved on the outside of the forming bars on both sides of the opening.
[0014] More preferably, the bottom of the first movable door is also provided with a hook formed by a forming strip extending to the bottom end and bending, and the hook closes the opening by engaging with the support strip.
[0015] More preferably, at least one reinforcing strip is provided in the middle of the first movable door.
[0016] The technical solution provided by this utility model has at least the following technical effects:
[0017] 1. Easy-to-use switch operation, suitable for high-frequency usage scenarios:
[0018] The cage door uses a latch-type locking structure as its core locking method, eliminating the need for keys or complicated tools. Simply pull the latch to open and close the cage, and it will lock into place naturally when closed. This is suitable for high-frequency birdcage use scenarios (such as daily feeding, water changing, cage cleaning, and observing the birds' condition), significantly reducing operational steps and improving efficiency.

[0041] This utility model has at least the following advantages:
[0042] 1. Easy-to-use switch operation, suitable for high-frequency usage scenarios:
[0043] The cage door uses a hook-and-loop latch structure as its core locking method (e.g., the hook 6 of the first movable door 3 engages with the support bar 2, and the limiting protrusion 7 of the second movable door 4 operates). No key or complicated tools are required; opening and closing are achieved simply by "pulling the hook 6" and "straightening the limiting part," and the door naturally locks in place when closed. This design is particularly suitable for high-frequency use scenarios of birdcages (such as daily feeding, water changing, cage cleaning, and observing the birds' condition), significantly reducing operational steps and improving efficiency.
[0044] 2. Simple and sturdy structure, highly durable:
[0045] The cage door body and the movable door are both composed of "intersecting forming strips 1 and support strips 2", which are integrally formed by bending and connecting. The number of parts is small (no precision lock core, gears and other complex parts). The mechanical principle directly relies on the interlocking of hooks 6 and support strips 2 and the guidance of the limiting structure. There are few wear points, and it is not easy to fail due to structural failure after long-term use.
[0046] The added limiting structure (limiting ring 5 is fitted on the outside of support bar 2 / forming bar 1, and the limiting part has a guiding function) can provide a stable sliding / rotation trajectory for the movable door, avoid jamming, deviation or shaking when opening and closing, ensure that the movable door always moves along a fixed path, and enhance the sealing performance after closing (preventing birds from crawling out).
[0047] The design of "reinforcing strip 9" in Example 2 further enhances the structural strength of the movable door, enabling it to withstand bird pecks or minor collisions and extending its service life.
[0048] 3. Clearly defined functional areas to accommodate diverse needs:
[0049] In Example 1, the separate design of the "first movable door 3 (main cage door)" and the "second movable door 4 (dedicated to the feeder opening)" achieves functional zoning: the main cage door is used for birds to enter and exit and for operations inside the cage, while the feeder opening movable door is only used for adding food / changing water. The two doors open and close independently without interfering with each other. This design avoids the risk of birds being startled or escaping due to frequent opening and closing of the main cage door, and can precisely meet specific needs (such as not needing to open the main cage door when feeding alone), making it more practical.
[0050] 4. Safety features designed to prevent birds from escaping:
[0051] The "tight engagement" between the hook 6 and the support bar 2 is the core anti-detachment guarantee. When closed, the hook 6 is naturally locked, and birds cannot pry or knock it open on their own.
[0052] The limiting ring 5, limiting part and other structures ensure accurate alignment when the movable door is closed, avoiding gaps caused by misalignment, and further reducing the possibility of birds crawling out;
[0053] The "movable connection" between the movable door and the cage door body (such as one end fixed and the other end snap-locked) takes into account both the flexibility of opening and closing and the stability of closing, preventing the movable door from falling off accidentally.
[0054] 5. Low cost, easy to produce, and high cost-effectiveness:
[0055] The overall structure is made of metal strips (forming strip 1 and support strip 2), which can be formed by bending and welding. No precision processing (such as lock cylinder, key and other parts) is required. The production process is simple, the material cost is low, and it is suitable for mass production. This can reduce the overall price of the birdcage and improve its cost performance.
[0056] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
