Preferably, the first standing wall is located at a lock pin contraction limit position.
Preferably, the distance between the second vertical wall and the first vertical wall is 0.25 to 0.3 of the total telescopic stroke of the lock pin.
Preferably, the inner diameter of the hole of the second vertical wall is 1.1 to 1.2 times the inner diameter of the hole of the first vertical wall.
Preferably, the openings of the locating tabs are provided with wear-resistant bushings.
The advantages of the present application include: the conventional design scheme of the pin lock seat mainly adopts a limiting guide sleeve to be mechanically connected with the front end face of the lock seat through a fastener. The pin lock seat designed by the invention does not use the structural form of a limiting guide sleeve, but optimizes the pin lock seat and changes the pin lock seat into an integral structure, two vertical walls are designed at the front end of the pin lock seat, two round holes are designed on opposite surfaces of a cavity, a lock pin is in close clearance fit with the round holes, when the pin lock is opened and closed, the motion tracks of the lock pin are ensured to be in the round holes in the cavity, and the lock pin does not exit from the round holes close to the pin lock body, so that the lock pin is ensured to move freely, the pin lock is opened and closed flexibly, and a lining is pressed in an opening in a positioning sheet to play a role of preventing abrasion.

Figure 2 is a schematic view of the installation of the guide pin lock housing and pin lock.
The lock comprises a pin lock base 1, a pin lock 2, a lock pin 3, a limiting angle box 4, a bushing 5, a bolt and nut assembly 6 and a positioning sheet 7.
Detailed Description
In order to make the implementation objects, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below with reference to the drawings in the embodiments of the present application. In the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The described embodiments are implementations that are part of this application and not all implementations. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application, and should not be construed as limiting the present application. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making creative efforts shall fall within the protection scope of the present application. Embodiments of the present application will be described in detail below with reference to the drawings.
A guide pin lock base is provided with a pin lock 2, a proper pin lock base component needs to be designed for installation, the pin lock 2 is provided with a lock pin 3, the pin lock base component is made of titanium alloy, and the pin lock base 1 is provided with a groove for accommodating the pin lock 2 and a limiting angle box 4 for guiding the lock pin 3;
the groove is a large rectangular cavity and is used for accommodating the pin lock 2, a protruding reinforcing rib is designed on the long side of the cavity, 4 bolt holes are reserved, and 2 groups of bolt and nut assemblies 6 are used for connecting the pin lock and the pin lock seat body;
the limit angle box 4 is provided with a first vertical wall and a second vertical wall along the telescopic direction of the lock pin 3, and the first vertical wall and the second vertical wall are respectively provided with a hole for the lock pin 3 to pass through.
In some alternative embodiments, the first standing wall is located at the limit of retraction of the lock pin 3.
In some alternative embodiments, the distance between the second vertical wall and the first vertical wall is 0.25-0.3 of the total telescopic stroke of the lock pin 3.
In some alternative embodiments, the inner diameter of the bore of the second upstanding wall is 1.1 to 1.2 times the inner diameter of the bore of the first upstanding wall.
