Description
Technical field
The utility model relates to a kind of mining safety device, is specifically related to a kind of mine car latch.
Background technology
Existing mine car latch, though can connect the mine car more than two preferably,, when mine car when not using, its idle mine car is very easy to be removed and arbitrarily abandons with latch, when reusing, causes very large inconvenience.
Notification number: CN2167074, the Chinese patent literature of the day for announcing: 1994.06.01 has been announced a kind of " Safety for mine car night bolt ", it has solved the drawback that existing latch need rotate an angle and be not suitable for automatic finger, it is by handle, pull bar, drag link sleeve safety box, latch, pin, ring, claw and constitute, when being the mine hoisting mine car, it, also is adapted to the occasion of pulling pin automatically simultaneously as the security insurance latch of anti-sport car.Notification number: CN2228538, the Chinese patent literature of the day for announcing: 1996.06.05 has been announced a kind of " Safety for mine car connection latch ", it is to have increased a baffle ring in addition on the basis of original mine car connection latch, make baffle ring block mine car termination connecting bore, and be unlikely to make the connection latch to break away from mine car, reaching the purpose of safety in production, for the safety in production in mine provides a good utensil.But above-mentioned two utility models still all do not have to solve and abandon, continue to use the shortcoming that has potential safety hazard easily.
Summary of the invention
The purpose of this utility model is to abandon, exist deficiencies such as potential safety hazard easily with latch at existing mine car, and a kind of a kind of mine car latch of abandoning, eliminating safe hidden trouble of being difficult for is provided.
The purpose of this utility model realizes by following technological means: a kind of mine car latch, comprise bracelet and latch, and be set with retainer on the meeting and discussing of mine car, an end of latch is connected with bracelet, and the other end of latch inserts retainer;
One side of described retainer is provided with an opening, treat that latch inserts retainer after, in described opening, insert key, and key and retainer linked together;
Described key has certain projection on direction in retainer;
The top of described latch is provided with the pin head of being wider than the latch other parts.
Described retainer and the connection mode of key are that welding or bolt, rivet are captiveed joint.
Described opening is arranged on the 15.5-29.5 millimeter place, lateral extent upper end of retainer, and cross sectional shape is set to rectangle.
The entire length of described latch is set to 295 millimeters, and the part except that the pin head is adopted cylindrical structure, and diameter is set to 37 millimeters.
Described pin head is adopted cylindrical structure, and its length is set to 48 millimeters, and diameter is set to 40 millimeters.
Described key is set to flat-shaped, and its flat thickness is set to 14 millimeters, described key in retainer on direction the length of bossing be set to the 19-24 millimeter.
Described retainer is set to the ring-type cylinder, and it highly is set to 47.5 millimeters, and outer diameter is set to 70 millimeters, and wall thickness is set to the 13-15 millimeter.
The rectangle of described opening highly is set to the 14-16 millimeter up and down.
The part of described latch except that the pin head adopted cylindrical structure, and the pin head is set to half and is the semicylinder concordant with the other parts periphery of latch, and second half is the semicylinder of radius greater than the radius of the other parts of latch.
Compared with prior art the utlity model has following tangible advantage: 1, this mine car has thoroughly solved latch with latch and has abandoned easily, causes the problem of potential safety hazard.2, this mine car is simple, easy for installation, with low cost with latch structure, is very easy to promote.
Description of drawings
Fig. 1 is a cross-sectional view of the present utility model;
Fig. 2 is the cross sectional representation at the utility model retainer position.
Among the figure, the 1-bracelet, the 2-retainer, the 3-key, the 4-latch, 5-sells head.
The specific embodiment
Below in conjunction with the description of drawings and the specific embodiment the utility model is described in further detail:
A kind of mine car latch as shown in Figure 1 and Figure 2 comprises bracelet 1 and latch 4, is set with retainer 2 on the meeting and discussing of mine car, and an end of latch 4 is connected with bracelet 1, and the other end of latch 4 inserts retainer 2; The entire length of described latch 4 is set to 295 millimeters, and diameter is set to 37 millimeters.
One side of described retainer 2 is provided with an opening, and described opening is arranged on the 15.5-29.5 millimeter place, lateral extent upper end of retainer 2, and cross sectional shape is set to rectangle, and described rectangle highly is set to the 14-16 millimeter up and down.After treating that latch 4 inserts retainer 2, in described opening, insert key 3, and key 3 and retainer 2 are linked together; Described retainer 2 is set to the ring-type cylinder, and it highly is set to 47.5 millimeters, and outer diameter is set to 70 millimeters, and wall thickness is set to the 13-15 millimeter.
In the described key 3 to length be set to thickness greater than retainer 2 walls, promptly be provided with certain projection to direction in key 3 retainers; Described key 3 is set to flat-shaped, and key 3 is concordant with the outer end of retainer 2, and its flat thickness is set to 14 millimeters, described key 3 in retainer 2 on direction the length of bossing be set to the 19-24 millimeter.These thickness are provided with, and have guaranteed that key 3 can be deep into certain position, when up mentioning latch 4, wide slightly pin 5 can be blocked.
