AI Technical Summary
The track connection of existing food vacuum freeze-drying equipment is prone to deformation due to longitudinal forces, resulting in problems such as poor butt and lag in the frame.
A circular rail butt locking mechanism is designed, using guide rail locking ends, pin hole ends, compression springs, locking tongues and limiting screws, so as to achieve the connection of the rail through the sliding connection and the compression spring. Closely locked to reduce deformation.
When the carriage is walking, the locking mechanism effectively reduces deformation at the track connection, avoids lag, and ensures the normal operation of the carriage. During reversing, the locking tongue and belt are realized through the cooperation of the key and the compression spring. The flexible separation and locking of the pin hole end ensures the normal reversal of the vehicle.

Technical Field
[0001] The utility model relates to the technical field of locking mechanisms, in particular to a circular rail docking locking mechanism for food vacuum freeze drying equipment. Background Art
[0002] The existing large-scale food vacuum freeze-drying equipment tracks usually use I-beam tracks. The track section usually contains many turning parts. The turning part of the track connection part is displaced and connected to other parts of the track by the thrust generated by the cylinder and the limiting device. The two sections of the track are tightly connected by the lateral thrust of the cylinder. After the connection is completed, the track is deformed by the longitudinal force when the frame car passes through, which can easily cause the track to be loosely connected, and it is easy to cause jamming when the frame car passes.

[0005] Preferably, one end of the compression spring contacts the end plug, and the rear end of the compression spring contacts the lock tongue. By providing the compression spring, the lock tongue is easy to reset.
[0006] Preferably, a shaft sleeve is arranged inside the locking tongue, and a locking pin is arranged inside the shaft sleeve. The shaft sleeve is supported by arranging the locking pin.
[0007] Preferably, a slot is provided inside the locking tongue, and the slot is slidably connected to the limit screw. By providing the slot, the limit screw can guide the movement of the locking tongue.
[0008] Preferably, a key is slidably connected inside the guide rail locking end, and the key is in contact with the shaft sleeve. By providing the key, the lock tongue is easy to separate from the end with the pin hole.
[0009] The beneficial effects of the utility model are as follows: when the trolley is running on the circular rail docking locking mechanism, the circular rail docking locking mechanism is subjected to a longitudinal force in an unlocked state, which causes extremely small deformation of the rail connection, does not interfere with the running of the trolley, ensures the normal operation of the trolley, and does not cause jamming; when the trolley needs to be reversed, it is only necessary to rotate the key so that the key hits the shaft sleeve, and the shaft sleeve drives the compression spring to be compressed, thereby causing the lock tongue to move and disengage the end with the pin hole, and the lock tongue and the other end with the pin hole are locked to ensure the normal operation of the trolley when reversing.
