Abstract
The utility model discloses a self-locking safety connection bolt arranged at the bottom of a flat-bed trailer, which relates to a safety connection bolt. The safety connection bolt solves problems that an existing connection bolt of a flat-bed trailer is complicated and difficult in assembly and disassembly, is easy to bounce to cause slippery of the flat-bed trailer sometimes when a locking part is not added to the existing connection bolt due to artificial negligence, and brings enormous hidden dangers for safety production of a coal mine. The self-locking safety connection bolt is provided with a holding groove. When the self-locking safety connection bolt is locked, one end of a lock plate is rotatably mounted in a second pin hole, and the other end of the lock plate is clamped on a boss. When the self-locking safety connection bolt is unlocked, one end of the lock plate is rotatably mounted in the second pin hole, and the other end of the lock plate is suspended below the bolt. When the self-locking safety connection bolt is self-locked, one end of the lock plate is rotatably mounted in the second pin hole, the other end of the lock plate is lifted via the upper end surface of a pin hole at the end of the flat-bed trailer, the lock plate rotates to a peripheral position of the bolt, and the bolt is inserted into the pin hole at the end of the flat-bed trailer. The self-locking safety connection bolt is applicable to mining flat-bed trailers.

The technical scheme of the utility model is: the safety of flat truck bottom band self-locking connects latch and comprises latch, first shank, block, second shank and locking plate, and the lower end of latch has mounting groove, and the end of latch is provided with boss, and the top of mounting groove has first pin-and-hole; Have second pin-and-hole on the relative side of the bottom of mounting groove and boss, first shank is located in first pin-and-hole, and the block and first shank rotate to be installed; And be positioned on the mounting groove, second shank is located in second pin-and-hole, and the locking plate and second shank rotate to be installed; And be positioned at mounting groove, during locking, an end of locking plate is rotatably installed in second pin-and-hole; The other end of locking plate is stuck on the boss, and during release, an end of locking plate is rotatably installed in second pin-and-hole; The other end of locking plate is suspended at the below of latch, and during self-locking, an end of locking plate is rotatably installed in second pin-and-hole; The other end of locking plate lifts through the pin-and-hole upper surface of flat truck termination, and locking plate rotates to the diameter place of latch, and latch inserts in the pin-and-hole of flat truck termination.
The utility model compared with prior art has following effect: 1. the utility model is simple in structure; Easy to operate, can realize self-locking, latch 1 can only insert and can not extract under self-locking state; Realize the locking of latch; Latch 1 can only be extracted and can not insert under released state, realizes the release of latch, and self-locking and release all only have one-way.2. the connection latch easy accessibility of the flat truck of the utility model, self-locking is firm, effectively raises the safety of Coal Production.
Description of drawings
Fig. 1 is that the latch 1 of the utility model gets into the blocking structural representation; Fig. 2 is the cutaway view along A-A line among Fig. 1; Fig. 3 is the latch 1 released state structural representation of the utility model; Fig. 4 is the latch 1 self-locking state structural representation of the utility model; Fig. 5 is the lateral plan after first shank 2 and second shank 4 insert latch 1.
The specific embodiment
The specific embodiment one: combine Fig. 1-Fig. 5 that this embodiment is described, the safety of the flat truck bottom band self-locking of this embodiment connects latch and comprises latch 1, first shank 2, block 3, second shank 4 and locking plate 5, and the lower end of latch 1 has mounting groove 1-1; And the end of latch 1 is provided with boss 1-2, and the top of mounting groove 1-1 has the first pin-and-hole 1-1-1, has the second pin-and-hole 1-1-2 on the side relative with boss 1-2 of the bottom of mounting groove 1-1; First shank 2 is located in the first pin-and-hole 1-1-1, and the block 3 and first shank 2 rotate to be installed, and is positioned on the mounting groove 1-1; Second shank 4 is located in the second pin-and-hole 1-1-2, and the locking plate 5 and second shank 4 rotate to be installed, and is positioned at mounting groove 1-1; During locking, an end of locking plate 5 is rotatably installed in the second pin-and-hole 1-1-2, and the other end of locking plate 5 is stuck on the boss 1-2; During release; One end of locking plate 5 is rotatably installed in the second pin-and-hole 1-1-2, and the other end of locking plate 5 is suspended at the below of latch 1, during self-locking; One end of locking plate 5 is rotatably installed in the second pin-and-hole 1-1-2; The other end of locking plate 5 lifts through the pin-and-hole upper surface of flat truck termination, and locking plate 5 rotates to the diameter place of latch 1, and latch 1 inserts in the pin-and-hole of flat truck termination.
The pin-and-hole of this embodiment flat truck termination be meet and discuss a last arm-tie 6, connection chain 7, meet and discuss in the middle of arm-tie 8, rubber meet and discuss 9 and the lower pulling plate 10 of meeting and discussing on offer the general name behind the through hole.
The specific embodiment two: combine Fig. 1 that this embodiment is described, have the block opening that matches with locking plate 5 on the block 3 of this embodiment.So be provided with, be convenient to the entering of latch 1.Other composition is identical with the specific embodiment one with annexation.
