Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-4, an embodiment of the present invention provides a technical solution: a linkage locking mechanism for a trailer balustrade, comprising:
a breast board 1;
the turntable 2 is positioned in the middle of one side of the breast board 1, and connecting pieces 3 are symmetrically fixed on one side of the turntable 2 far away from the breast board 1;
the first end of the rotating shaft 4 is fixed in the middle of the rotating disc 2, and the first end and the second end of the rotating shaft 4 can be rotatably clamped on the breast board 1;
the handle 5 is fixed with the second end of the rotating shaft 4;
the first end of the lock rod 6 is provided with a sliding groove 7, the connecting piece 3 is inserted into the sliding groove 7 in a sliding manner, a pin rod 8 is rotatably inserted between the first end and the second end of the lock rod 6, and one end of the pin rod 8 is fixed on the breast board 1;
the mounting rack 9 is symmetrically arranged on two sides of the breast board 1, a lock groove 10 is formed in one side of the mounting rack 2, and the second end of the lock rod 6 is rotatably inserted into the lock groove 10.
Through the linkage locking mechanism for the trailer breast board, it can be seen that before the locking operation is carried out, the mounting frames 9 need to be installed on the two sides of the trailer in advance, and when goods are loaded, the breast board 1 is firstly used for linkage locking of the mounting frames 9.
When linkage locking is performed, the handle 5 is firstly pulled, so that the shaft lever 5 rotates along with the rotation, the rotating shaft lever 5 can drive the turntable 2 to rotate, the connecting piece 3 on the turntable 2 can move up and down in the sliding groove 7, and one end of the locking rod 6 is pulled by the connecting piece 3 to rotate around the pin rod 8 by a certain angle;
when the pin rod 8 rotates to be perpendicular to the side surface of the balustrade 1, the extension amount of the second end of the pin rod 8 is the largest, and the pin rod 8 is inserted into the locking groove 10 of the mounting frame 9, so that the locking work of the balustrade 1 on the mounting frame 9 is completed;
when pin 8 rotates to not mutually perpendicular with breast board 1 side, along with pin 8 and breast board 1's side contained angle constantly reduces, the second end of pin 8 can break away from the locked groove 10 on the mounting bracket 9 gradually this moment, takes in to breast board 1 one side, when pin 8 second end breaks away from this locked groove 10 completely, has accomplished breast board 1 this moment to the linkage unblock work of mounting bracket 9.
Through the linkage locking and unlocking work of the mode, the operation control of a worker through the handle 5 on one side of the breast board 1 can be facilitated, the breast board 1 is easily installed and detached, simplicity and convenience are achieved, and the transportation stability of the installed breast board 1 can be improved by simultaneously setting a plurality of groups of pin rods 8 which are parallel to each other on the same side on the turntable 2 and locking the installation frame 9 together.
The fence board 1 comprises a frame 11 and a panel 12, the panel 12 is fixed around one side of the frame 11, slots 13 are formed in two sides of the frame 11, the second end of the lock rod 6 penetrates through the slots 13, and the height of each slot 13 is larger than the width of the lock rod 6; in the assembling process of the breast board 1, materials can be saved for manufacturing the breast board by utilizing the panel 12 and the frame 11, the breast board 1 made in the mode is light in material and convenient to carry, and the pin rod 6 can conveniently penetrate through the slot 13 to complete the rotation action by virtue of the slot 13 formed in the frame 11.
When the handle 5 is used for controlling the rotation of the rotating shaft 2, the locking depth of the locking rod 6 to the locking groove 10 cannot be well determined, so that a torsion spring 14 is sleeved on the rotating shaft 4 between one side of the breast board 1 far away from the turntable 2 and the handle 5, one end of the torsion spring 14 is connected with the handle 5, and the other end of the torsion spring 14 is connected with the breast board 1; that is, when the handle 5 is rotated, the rotating shaft 2 rotates along with the rotating shaft, the second end of the lock rod 6 is contracted to be separated from the lock groove 10, the torsion spring 14 stores energy at the time, after the balustrade 1 is placed at the preset installation position and the handle 5 is released, the torsion spring 14 releases torsion energy to drive the rotating shaft 2 to rotate, and then the second end of the lock rod 6 is inserted into the preset depth of the lock groove 10 to complete locking.
In order to facilitate the locking operation of the locking bar 6 to the locking groove 10, optionally, the pin 8 is located at a side near the second end of the locking bar 6; that is, the length of the locking rod 6 at one end of the connecting piece 3 is greater than the length of the locking rod 6 at one side close to the locking groove 10, that is, when the first end of the locking rod 6 rotates greatly, the second end of the locking rod 6 will be separated from the locking groove 10, so as to prevent misoperation and the second end of the locking rod 6 which is caused by touching the handle 5 to be separated from the locking groove 10.
In order to facilitate the rotation driving control of the turntable 2, lubricating oil layers are coated on two sides of the turntable 2; it is possible to facilitate reduction of abrasion between the turntable 2 and the lock lever 6 and between the turntable 2 and the balustrade 1 and to prevent the surface thereof from being rusted to make it difficult to rotate the turntable 2 by the handle 5.
