Description
Technical field
The utility model relates to mine equipment field, specifically refers to a kind of lock clasp device.
Background technique
During current domestic hydraulic support is produced, the locking of push rod bearing pin generally adopts U-shaped card to coordinate U-shaped deck to connect locking, but U-shaped deck required precision is high, complex process.Connect bearing pin more need car go out specific groove allow U-shaped card through in order to locking, not only increase operation, too increase difficulty of processing.The installation of U-shaped card, dismounting also need special tool, inefficiency, and labor intensity is large, therefore in the past this locking mode not only processing cost is high, and subsequent maintenance cost is also high.
Model utility content
Technical problem to be solved in the utility model is to provide that a kind of structure is simple, convenient disassembly, lower-cost lock clasp device.
For realizing above-mentioned technical purpose, the utility model adopts following technological scheme to be achieved.
The tight device of push rod bearing pin spring latch, comprises spring pin, bearing pin, key seat, push rod ear seat; Described push rod ear seat is welded key seat, and bearing pin is through key seat and push rod ear seat; Spring pin comprises spring ring and pin rod, and described pin rod inserts on described key seat and bearing pin, and described spring ring is sheathed on described key seat.
As technological scheme further, described spring ring is movably connected on described pin rod.
As technological scheme further, described bearing pin is provided with lock clasp hole.
As technological scheme further, described key seat is circular, and centre is key seat hole, and side is provided with key seat locking hole; Described bearing pin is through described key seat hole, and described key seat locking hole is coaxial with described lock clasp hole.
As technological scheme further, described push rod ear seat comprises the first ear seat and the second ear seat, first ear seat is provided with the first ear bore coaxial with described key seat hole, and the second ear seat is provided with the second ear bore, and described bearing pin inserts described first ear bore and the second ear bore successively.
As technological scheme further, the first ear bore is different from the second ear bore height.
The beneficial effects of the utility model are:
Spring pin inserts in homemade key seat by the utility model, manually breaks spring ring to bearing pin position, utilizes the restoring force of spring pin spring ring self to make spring ring position keep fixing, thus coordinates by spring pin and key seat the effect played and lock bearing pin; Simple and reliable for structure, install, convenient disassembly, cost is lower, and assembling does not rely on instrument, and key seat difficulty of processing is low, and technique is simple, and maintenance cost is low, just with apply.
