Abstract
Description
Technical Field
[0001] This utility model relates to the field of pet door technology, specifically a concealed latch-type anti-pinch pet door. Background Technology
[0002] The emergence of pet doors is closely related to the evolution of pet ownership. In the early days of family pet ownership, simple methods such as drilling holes in doors or walls were used to facilitate pets' entry and exit. This could only meet basic passage needs and was prone to causing indoor heat loss and mosquito intrusion. At the same time, it could not restrict the time pets could enter and exit. In recent years, with the booming development of the pet economy and the advancement of technology, pet doors have entered a stage of functional development. Features such as anti-pinch and concealment have become research and development hotspots. The products are gradually transforming from simple passage tools to devices that combine safety protection and home integration.
[0003] However, the existing pet doors on the market have the following problems in actual use: conventional pet doors are designed to hang down 360 degrees, and when pets suddenly move back and forth, there are safety hazards such as pets getting their heads, tails, or hands stuck in the door. In addition, the door lock is exposed and pets can easily pry it open, causing the pet door lock to fail, thus making it difficult to achieve the effect of closing the door to isolate and restrict pets. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a concealed latch-type anti-pinch pet door, which solves the problem that the concealed latch-type anti-pinch pet door has poor restriction effect in the prior art.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a concealed latch-type anti-pinch pet door, comprising a main frame, a door body, a first latch rod, and a second latch rod. The side of the main frame is provided with a fourth main frame hole, a first main frame hole, a second main frame hole, and a third main frame hole in sequence from top to bottom. The side of the door body is provided with a first locking hole, a second locking hole, and a third locking hole in sequence from top to bottom. A first built-in protrusion is provided at one end of the interior of the second locking hole, and a second built-in protrusion is provided at the other end of the interior of the third locking hole.
[0008] Optionally, a door frame is fixedly installed on the side of the main frame, and the internal through grooves of the main frame and the door frame are correspondingly matched.
[0009] Optionally, the first main frame hole, the second main frame hole, the third main frame hole and the fourth main frame hole are all opened at the two ends of the main frame body.
[0010] Optionally, a fitting shaft is rotatably mounted inside the first main frame hole and the first locking hole to form a hinge switch.
[0011] Optionally, the second main frame hole and the second locking hole are provided correspondingly, and the third main frame hole and the third locking hole are provided correspondingly.
[0012] Optionally, a first pin is slidably fitted inside the second main frame hole and the second locking hole, and a second pin is slidably fitted inside the third main frame hole and the third locking hole.
[0013] (III) Beneficial Effects
[0014] This utility model provides a concealed latch-type anti-pinch pet door, which has the following beneficial effects:
[0015] This concealed latch-type anti-pinch pet door works by pushing the end of the first latch rod at the first built-in protrusion when the door is closed and locked. This causes the first latch rod to extend partially outward in the second locking hole inside the door, locking it in conjunction with the second main frame hole on one side of the main frame. Simultaneously, pushing the end of the second latch rod at the second built-in protrusion causes the second latch rod to extend partially outward in the third locking hole inside the door, locking it in conjunction with the third main frame hole on the other side of the main frame. This forms a concealed latch lock. Pushing the first and second latch rods in the opposite direction causes them to move out of the second and third main frame holes and engage in locking. The concealed door lock makes it difficult for pets to pry it open, providing stable door locking and isolation functions.
[0016] This concealed latch-type anti-pinch pet door flips 180 degrees upwards around the first main frame hole and accessory shaft. At this time, the first latch extends outwards in the second locking hole inside the door body and locks with the fourth main frame hole on one side of the main frame. This achieves a concealed, locked 180-degree open mode for the pet door, allowing pets to enter and exit freely without being obstructed by a drooping pet door, thus avoiding pet safety issues caused by sudden movements. The first and second built-in protrusions restrict the movement of the first and second latches, preventing problems caused by excessive pushing and pulling that could hinder the use of the pet door.
