DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

To make the technical problems to be solved in the present invention, the technical solution and the beneficial effects clearer, the present invention is further described in detail hereinafter with reference to embodiments. It should be understood that specific embodiments described herein are only used for explaining the present invention and are not intended to limit the present invention.

It should be noted that when an element is expressed to be “fixed” or “arranged” on another element, it may be directly or indirectly on another element. When one element is referred to being “connected” to another element, it may be directly or indirectly connected to another element.

It should be understood that the orientation or position relationship indicated by the terms “up”, “down”, “front”, “rear”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, and the like is based on the orientation or position relationship shown in the drawings, it is only for the convenience of description of the present invention and simplification of the description, and it is not to indicate or imply that the indicated device or element must have a specific orientation in the specification, and be constructed and operated in a specific orientation. Therefore, the terms should not be understood as limiting the present invention.

Moreover, the terms “first”, “second” and “third” are only used for descriptive purposes, but cannot be understood as indicating or implying relative importance, or implicitly indicating the number of indicated technical features. Therefore, the feature defined by “first” and “second” may explicitly or implicitly include one or more of the features.

With reference toFIG.1toFIG.4, in an embodiment of the present invention, a high-reliability flight case with an auxiliary locking function comprises a case body1and a case door2located at an opening of the case body1, an outer wall of the case door2is fixedly connected with an iron shaft3, the outer wall of the case door2is fixedly connected with a box body6, the box body6is symmetrically connected with two inserting rods4through a rebound mechanism, connecting seats10are integrally formed at positions corresponding to ends of the iron shaft3and ends of the inserting rods4on an outer wall of an opening of the case body1, inserting holes matched with the iron shaft3and the inserting rods4are formed in the connecting seats10in a penetrating mode, one end of the inserting hole oriented to the case door2is set as a conical flareout, an outer wall of the connecting seat10is clamped with an adapter seat11, a hand-screwed nut13is movably arranged on the adapter seat11in a penetrating mode, two ends of the iron shaft3and one ends of the inserting rods4far away from the box body6are all provided with an external thread, and the threaded ends of the iron shaft3and the inserting rods4are located in corresponding connecting seats10and matched with the hand-screwed nuts13.

The rebound mechanism comprises a spring8located in the box body6, two ends of the spring8are both provided with a connecting plate7, and one end of the inserting rod4penetrates through the outer wall of the box body6to be fixedly connected with corresponding connecting plate7.

The spring8is matched with two connecting plates7, so that two inserting rods4can be pushed by the spring8at the same time.

An outer wall of the inserting rod4close to the box body6is bent to form a protrusion5, the outer wall of the inserting rod4is slidably sleeved with a guide sleeve9, and the guide sleeve9is fixedly connected with the case door2.

The protrusion5is arranged, which is convenient to operate the inserting rod4, and the guide sleeve9can keep the inserting rod4and improve a stability of the inserting rod4during moving at the same time.

An outer wall of the adapter seat11is provided with a plurality of buckles12, and matched clamping grooves are arranged at positions on the outer wall of the connecting seat10corresponding to the buckles12.

The buckle12is matched with the clamping groove, which is convenient to assemble the adapter seat11on the connecting seat10.

A conical boss is integrally formed on an outer wall of one end of the hand-screwed nut13located in the adapter seat11, a through hole matched with the hand-screwed nut13is formed in the adapter seat11, and an outer diameter of the conical boss close to an end with the through hole is larger than an aperture of the through hole. In order to be convenient to insert the conical hand-screwed bolt13into corresponding through hole during assembling, the hand-screwed bolt13and the adapter seat11are both made of a plastic material with certain elasticity.

The conical boss is arranged, so that the hand-screwed bolt13can be limited on the adapter seat11, thus avoiding the hand-screwed bolt13from falling off the adapter seat11.

A working principle of the present invention is that:according to the flight case, when the flight case is used for transporting pets, the hand-screwed bolts13are rotated to be matched with the threaded ends of corresponding iron shaft3or inserting rods4to lock the iron shaft3and the inserting rods4, so that a stability of connection between the case door2and the case body1is effectively improved, the case door2is avoided from being automatically opened during transportation, operation is easy and convenient, and when the hand-screwed bolts13are not tightened, the inserting rods4are operated through the protrusions5to realize quick opening and closing of the case door2.

The inserting hole with the conical flareout in the connecting seat10can guide the end of the inserting rod4during insertion of the inserting rod4, so that it is more convenient to insert the inserting rod4into corresponding inserting hole.

Although the present invention is described in detail with reference to the embodiments above, those skilled in the art may still modify the technical solutions recorded in the embodiments above, or make equivalent substitutions to some of the technical features. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should fall within the scope of protection of the present invention.
