Abstract
The utility model discloses a self-locking bolt for a mining car, which comprises a bolt body (1) with a central through hole, wherein a bolt body lock slot (7) is arranged in the middle of the lower part of the bolt body (1); a limiting shaft (6) is transversely arranged in the bolt body lock slot (7); a tabular locking plate (5) is articulated on the limiting shaft (6); a pull rod (2) is arranged in the central through hole; a connecting pin shaft (4) is fixed at the lower end of the pull rod (2); a locking plate chute (8) is arranged on the locking plate (5); and the connecting pin shaft (4) is mounted in the locking plate chute (8). The self-locking bolt disclosed by the utility model has the characteristics of lightness, flexibility, simple structure, and capabilities of self-locking without pulling and unlocking by once pulling; and the self-locking bolt is not only applicable to use of an inclined shaft mining car, but also applicable to various types of traction equipment.
Description
Technical field
The utility model relates to a kind of latch with coupler lock function, is specifically related to a kind of mine car and uses from the locking latch.
Background technology
The employed mine car latch majority in mine is the cylinder plugs of φ 40 * 170 at present, inserts from top to bottom during use, and there is a location shaft shoulder upper end.Because locking can not be realized in the latch lower end, when this latch uses in the ramp of inclined shaft environment, be easy to especially come off, cause the coaster phenomenon, there is bigger potential safety hazard.
The utility model content
The utility model technical matters to be solved is, provides a kind of mine car to use from the locking latch, can automatic blocking after adopting this latch to insert mine car striking head hole and be connected annular distance, have the caducous defective of mine car latch now to overcome.
The technical scheme that the utility model adopted is following:
A kind of mine car is used from the locking latch, comprises the latch body with central through hole, it is characterized in that: have a latch body locked groove in the middle of the bottom of latch body, in latch body locked groove, be horizontally arranged with limit shaft, on limit shaft, be hinged with flat locking plate; Be provided with pull bar in the described central through hole, the lower end of pull bar is fixed with the connection bearing pin; On locking plate, offer a locking plate skewed slot, described connecting pin axle mounting is in this locking plate skewed slot.
24 °～26 ° of angles between the trend of locking plate skewed slot and the trend of locking plate.
The good effect of the utility model is: mention pull bar during use; The bearing pin that is connected between locking plate and the pull bar moves in the locking plate skewed slot; Locking plate rotates around limit shaft, and locking plate is taken among the latch body locked groove, during this latch is inserted the mine car striking head hole and is connected annular distance.Releasing lever then; Locking plate leans on from recoiling the limit shaft contrarotation; The bearing pin that is connected between locking plate and the pull bar oppositely moves in the locking plate skewed slot, and the upper end of locking plate is from latch body locked groove lopsidedness and stretch out, and stops latch to move up; Thereby play the locking effect, solved the caducous problem of mine car latch.
The utlity model has light and flexible, simple in structure, do not pull out self-locking, one pulls out the characteristics of release, not only is applicable to the use of slope vehicle, also applicable to various tractor equipments.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is one of A-A cutaway view of Fig. 1, and what this figure showed is that pull bar is mentioned state.
Fig. 3 be Fig. 1 the A-A cutaway view two, what this figure showed is the state that locking plate stretches out latch body locked groove.
The specific embodiment
Further specify the utility model below in conjunction with accompanying drawing and embodiment.
As shown in Figure 1, the utility model comprises the latch body 1 with central through hole, has a latch body locked groove 7 in the middle of the bottom of latch body 1, in latch body locked groove 7, is horizontally arranged with limit shaft 6, on limit shaft 6, is hinged with flat locking plate 5.Be provided with pull bar 2 in the described central through hole, these pull bar 2 upper ends have pull bar handle 3.The lower end of pull bar 2 is fixed with and connects bearing pin 4.
Like Fig. 2,3, on locking plate 5, offer a locking plate skewed slot 8, described connection bearing pin 4 is installed in this locking plate skewed slot 8 movably.
To connect bearing pin 4 mobile locking plate skewed slot 8 in locking plate skewed slot 8 has specific trend freely in order to make, generally be designed to 24 °～26 ° of angles between the trend of trend and locking plate 5 of locking plate skewed slot 8.Promptly decontroled when being in free state at pull bar 2, like Fig. 3 state, the trend of locking plate skewed slot 8 is horizontal by 24 °～26 ° angle.
Claims (2)
1. a mine car is used from the locking latch; Comprise latch body (1) with central through hole; It is characterized in that: have a latch body locked groove (7) in the middle of the bottom of latch body (1), in latch body locked groove (7), be horizontally arranged with limit shaft (6), on limit shaft (6), be hinged with flat locking plate (5); Be provided with pull bar (2) in the described central through hole, the lower end of pull bar (2) is fixed with and connects bearing pin (4); On locking plate (5), offer a locking plate skewed slot (8), described connection bearing pin (4) is installed in this locking plate skewed slot (8).
2. mine car as claimed in claim 1 is used from the locking latch, it is characterized in that: 24 °～26 ° of the angles between the trend of the trend of locking plate skewed slot (8) and locking plate (5).
