Description

Technical Field

[0001] The present invention belongs to the technical field of pet gates, and in particular relates to a pet gate connection structure and a multilateral safety pet telescopic gate. Background Art

[0002] Pet gates are important tools for space isolation and safety in modern pet-raising households. Their design must take into account practicality, safety, and home adaptability. Physical barriers are used to divide pet activity areas to prevent pets from entering restricted areas such as kitchens and bedrooms, or to prevent young pets / new pets from damaging furniture. For example, using a gate to separate the living room from the kitchen can prevent pets from coming into contact with dangerous items, and prevent pets from accidentally getting lost or mistakenly entering dangerous areas (such as stairwells and balconies). For kittens or small dogs, a 170 cm high gate can effectively prevent them from jumping and escaping; the automatic closing function can prevent the owner from neglecting the pet and escaping, and the temporary isolation function makes it easier for the owner to handle emergencies (such as receiving visitors or picking up express deliveries). Some gates are designed with magnetic latches, which automatically close after opening the door, eliminating the need to manually lock the door, thereby improving ease of use;

[0003] After searching, the announcement number CN208416110U is a threshold-free safety fence, which includes a first guardrail, a gate and a connecting mechanism connecting the first guardrail and the gate. The first guardrail includes a first crossbar and a second crossbar arranged in parallel, and the first crossbar is located above the second crossbar. The gate includes a second guardrail, a handle, a column and a fixing assembly. The second guardrail includes a third crossbar and a fourth crossbar arranged in parallel, the axis of the third crossbar is coplanar with the axis of the first crossbar, and the axis of the fourth crossbar is coplanar with the axis of the second crossbar. The handle is connected to the third crossbar, and the fixing assembly can not only fix the handle and the column, but also unlock the handle and the column, and then the handle can drive the second guardrail to rotate relative to the column. The above-mentioned threshold-free safety fence is provided with a gate, and by rotating the second guardrail, the purpose of opening and closing can be achieved to facilitate entry and exit. Moreover, the threshold is omitted, so that people can avoid being tripped by the threshold when entering and exiting the fence, thereby improving the safety of the fence; its defect is that: although the utility model adopts a corresponding connecting mechanism to provide the fence with rotation ability, the connecting mechanism according to the utility model is mostly connected together by a threaded connection method, and there is a problem that the corresponding threaded rotating block is unscrewed during the rotation of the guardrail, which leads to the failure of the entire fence structure. Improvements are needed. Therefore, it is particularly important to design a pet gate fence connection structure and a multilateral safety pet telescopic gate fence to solve the above-mentioned defects.

As the connecting column rotates, the fixing blocks will move above the first limiting block. At this time, the first compression spring pushes the first limiting block to move upward, contacting and supporting the lower surface of the fixing block. At the same time, the second limiting block inside the sleeve will move toward the fixing block under the interaction of the elastic frame and the positioning block until it enters the second limiting groove at the top of the fixing block, thereby realizing a limiting connection between the fixing block and the sleeve. The dual limiting action of the first limiting block and the second limiting block ensures a stable connection between the connecting column and the sleeve and prevents the connection from loosening. The connection component is cleverly designed. The user only needs to simply rotate the connecting column to complete the connection process. The operation is simple and quick.

[0023] When the locking cam is in the closed position, the locking cam is engaged with the locking ball on the fixing ring, and the locking cam is engaged with the locking ball on the fixing ring, thereby locking the locking cam and keeping the third locking cam in the closed position.
