The sleeve connecting spring catch mechanism is fixed at straight edge, and one end of the telescopic shaft of spring catch mechanism arranges edge structure, and blade is tied
The teeth groove on structure correspondence tooth type handle bolt surface, realizes positioning and locking in being inserted into teeth groove by edge structure.
As further program of the utility model: the sleeve of described spring catch mechanism is arranged on the outside of telescopic shaft, and
Spring is set in sleeve, and the two ends of spring are respectively fixedly connected with on sleeve and telescopic shaft.
As further program of the utility model: the sleeve surface of described spring catch mechanism arranges through hole, and spring catch
Offer two through holes on the telescopic shaft of mechanism, when the through hole of sleeve surface is the most coaxial with on telescopic shaft two through holes, stretch
The edge structure of contracting axle one end away from or the teeth groove on grafting tooth type handle bolt surface, and safety plug sequentially passes through sleeve surface
Through hole and the through hole on telescopic shaft fixing be connected.
As further program of the utility model: two the most perpendicular relations of through hole on described telescopic shaft.
As further program of the utility model: the middle part of connection rotating shaft is fixed in one end of described tooth type handle bolt,
And the two ends of rotating shaft are movably connected on the inwall of fluting, the fixing seat upper surface of rotating shaft correspondence position offers screwed hole, screw thread
Hole female thread connects vertical set lever, is compressed by vertical set lever or loosens rotating shaft.
Compared with prior art, the beneficial effects of the utility model are:
1) it is spring pin locking gear that locking device is beaten the locking method optimizing of insurance, the most simple to operate, and
Safe and reliable；
2) increase vertical set lever, it is possible to dolly in vertical direction locking packing crates, overcome vertical direction the completeest
The mode of full locking, improves vertical locking safety, makes case inner support car fixing more reliable and more stable.
Accompanying drawing explanation
Fig. 1 is structure top view of the present utility model.
Fig. 2 is structural representation during this utility model locking.
Fig. 3 is this utility model structural representation when unclamping.
Fig. 4 is the structural representation that tooth type handle bolt rotates.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1～4, in this utility model embodiment, dolly locking device in a kind of packing crates, including dolly in case
1, fixing seat 2, tooth type handle bolt 3, safety plug 4, vertical set lever 5 and spring catch mechanism 6, the top of described fixing seat 2
It is fixedly connected in packing crates and the side of dolly 1 run trace in case, in order to dolly 1 in fixed case, described fixing seat 2
Top arranges longitudinal fluting, and one end of tooth type handle bolt 3 is movably connected on the inwall of fluting by rotating shaft, so that
Tooth type handle bolt 3 with axis of rotation, thus can adjust the position of tooth type handle bolt 3.
The sleeve being connected spring catch mechanism 6, spring catch mechanism 6 are fixed in the edge that in described case, dolly 1 is vertical with fixing seat 2
One end of telescopic shaft edge structure, the teeth groove on edge structure correspondence tooth type handle bolt 3 surface are set, inserted by edge structure
Entering and realize positioning and locking in teeth groove, the sleeve of described spring catch mechanism 6 is arranged on the outside of telescopic shaft, and arranges bullet in sleeve
Spring, and the two ends of spring are respectively fixedly connected with on sleeve and telescopic shaft, in order to utilize the elastic force of spring to reset.
The sleeve surface of described spring catch mechanism 6 arrange offer on through hole, and the telescopic shaft of spring catch mechanism 6 two lead to
Hole, when the through hole of sleeve surface is the most coaxial with on telescopic shaft two through holes, the edge structure of telescopic shaft one end away from or
The teeth groove on grafting tooth type handle bolt 3 surface, and sequentially pass through the through hole of sleeve surface and logical on telescopic shaft by safety plug 4
Hole is fixing to be connected, thus in guard box dolly 1 be not locked and under locking state more stable, it is to avoid beat and cause connection not
Steady or the phenomenon of interference moving of car.
Two the most perpendicular relations of through hole on described telescopic shaft, in order to adjust the pass of edge structure and teeth groove
System, when edge structure and teeth groove compact siro spinning technology, edge structure is parallel to be plugged in teeth groove, and when edge structure and teeth groove away from
Time, by rotary extension axle so that edge structure and teeth groove the most in vertical state, thus avoid special circumstances to cause
Jerk, double shield.
The middle part of connection rotating shaft is fixed in one end of described tooth type handle bolt 3, and the two ends of rotating shaft are movably connected in fluting
Inwall on, fixing seat 2 upper surface of rotating shaft correspondence position offers screwed hole, and screwed hole female thread connects vertical set lever 5,
Compress by vertical set lever 5 or loosen rotating shaft, preventing tooth type handle bolt 3 from beating, it is ensured that the stability of connection.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this practicality in other specific forms new
