Example Embodiment

[0019] The embodiments of the present invention will be further described below in conjunction with the drawings.

[0020] See attached figure 1 , Attached figure 2 , Attached image 3 And Figure 4 , A locking device that can be automatically released according to the present invention includes a guide seat 1, a supporting base plate 10, a telescopic rod 6 and a positioning hole seat 14;

[0021] The lower end of the guide seat 1 is fixedly connected to the support substrate 10, and a square guide cavity is formed in the middle. A limit hole 15 is opened above the guide seat 1, and a disengagement mechanism is provided in the limit hole 15;

[0022] The telescopic rod 6 is located in the square guide cavity and can be freely expanded and contracted therein. The middle section of the telescopic rod 6 is square, and the cross sections at both ends are circular. The side length of the square is greater than the diameter of the circle, so There is a cylindrical guide hole 16 in the mi...

Abstract

The invention discloses a locking device with the automatic unlocking function, belongs to the technical field of mechanical locking devices, and aims to solve the problems that working efficiency is low and operation is inconvenient in the prior art. The locking device comprises a guide base, a supporting base plate, a telescopic rod and a locating hole base, wherein the lower end of the guide base is fixedly connected with the supporting base plate, a square guide cavity is formed in the middle of the guide base, a limiting hole is formed in the upper portion of the guide base, and an unlocking mechanism is arranged in the limiting hole; the telescopic rod is located in the square guide cavity and can extend and contract freely in the square guide cavity, the cross section of the middle of the telescopic rod is square, the cross sections of the two ends of the telescopic rod are round, and a cylindrical guide hole is formed in the middle of the square cross section; a locking mechanism is arranged in the cylindrical guide hole, a compression spring is arranged at one end of the telescopic rod, one end of the compression spring makes contact with the square cross section of the middle of the telescopic rod, the other end of the compression spring makes contact with a compression spring base fixed to the guide base, and an unlocking limiting plate is fixed to the other end of the guide base; the telescopic rod extends and contracts in the square guide cavity to be matched with or separated from a locating hole in the locating hole base.

Description

technical field [0001] The invention belongs to the technical field of mechanical locking devices, and in particular relates to a locking device that can be automatically disengaged. Background technique [0002] Theodolite or stable platform and other equipment with active links need to lock the rotating part during transportation or assembly to protect the safety of the equipment. In the prior art, a mechanical device for manually inserting and pulling out the telescopic rod is often used to realize the fixed-point locking of the rotary part. This kind of locking device is not conducive to the fast locking of the rotary equipment, and the work efficiency is low; in addition, when the equipment needs to be disengaged quickly, the operator must overcome the elastic force of the compression spring and pull out the telescopic rod to release the equipment, which is not only laborious, but also Time-consuming, seriously affecting the quick start of the rotary equipment.
