Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

In the description of the present invention, "a plurality" means two or more unless otherwise specified; the terms "upper", "lower", "left", "right", "inner", "outer", "front", "rear", "head", "tail", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, should not be construed as limiting the invention. Furthermore, the terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, e.g., as being fixed or detachable or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1-5, a novel lock catch comprises a lock hook 1, a lock catch base 2, a handle 3, a tension spring 5 and a locking pin 6. The latch hook 1 has a pin joint part, the latch holder 2 has a pin joint part and a limit hook groove 9, and the handle 3 has a U-shaped structure.

The upper part of the lock catch seat 2 is provided with the inverted U-shaped handle 3, the pin joint part of the lock catch seat 2 is connected with the handle 3 through a pin shaft 4 which is arranged in a penetrating way, and the tail parts of the two ends of the pin shaft 4 are riveted through a hammer. The handle 3 is connected with the pin joint part of the lock hook 1 through another pin shaft 10 which is arranged in a penetrating way, and the tail parts of the two ends of the pin shaft 10 are riveted by hammering.

Still set up the spout 8 that link up on the handle 3, penetrate in the spout 8 and be equipped with stop pin 6, and extension spring 5 has been placed to the inboard of handle 3, and the pot head of extension spring 5 is established and is fixed on round pin axle 10, and the pot head of extension spring 5 is established and is fixed on spacing sleeve 7, and the middle part of limiting sleeve 7 has the screw hole certainly, and limiting sleeve 7 cover is established on stop pin 6 and is connected with stop pin 6 threaded connection, and both constitute the complex. The combination body of the limiting sleeve 7 and the locking pin 6 can move along the sliding groove 8 of the handle 3 through the tension spring 5.

The position of the lock catch seat 2, which is positioned in the limit hook groove 9, is also provided with a lead sealing hole 11 in a through way. A thin iron wire penetrates through the lead sealing hole 11, and then a lead weight is hung on the lead sealing hole, so that the lock catch can be lead-sealed like a common lock catch.

The use principle is as follows:

when the locking device is opened, the locking pin 6 does not enter the limiting hook groove 9 of the lock catch seat 2, when the lock catch needs to be compressed, the handle 3 is pressed to be closed with the lock catch seat 2, at the moment, the locking pin 6 slides along the inclined plane above the limiting hook groove 9 of the lock catch seat 2 until the end surface of the limiting hook groove 9 continues to press down the handle 3, when the locking pin 6 on the handle 3 is aligned with the limiting hook groove 9, the locking pin 6 is pulled into the limiting hook groove 9 of the lock catch seat 2 under the action of the tension spring, the handle 3 cannot be pressed down continuously and cannot be pulled up, and therefore the locking purpose is achieved. When unlocking, the locking pin 6 is pulled to be separated from the hook groove of the lock catch seat 2, and then the unlocking is completed.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical scope of the present invention and the equivalent alternatives or modifications according to the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
