Description
Technical field
The utility model relates to a kind of photographic goods, particularly a kind of tripod pin pipe locking device.
Background technique
People are when photography or mapping, and regular meeting uses tripod as support, carries for the ease of it, and mostly each foot rest of tripod is to be made up of two or more grades pipe, therefore just had multiple valve locking problem.Mostly the tripod of Chu Shouing is to cooperate by screwed pipe joint and threaded pipe and realizes that it is simple in structure in the market, but shortcoming such as it is unreliable to exist locking, and bearing capacity is relatively poor.Therefore need to propose a kind of reliable lock, carry big multiple valve locking device.
The model utility content
The utility model provides a kind of multiple valve locking device, and its main purpose is to realize a kind of reliable lock, the multiple valve locking device that bearing capacity is big.The purpose of this utility model realizes by following measure:
Described diode overcoat has described one-level pipe, described one-level pipe and described diode are provided with locking device outward, described locking device is by connecting sleeve, plastic tube and locking knob constitute, described locking knob inner chamber is provided with described connecting sleeve and described plastic tube, described locking knob inwall is provided with screw thread, one end is provided with back-up ring, described connecting sleeve outer wall is provided with outside thread, described locking knob is threaded with described connecting sleeve, the back-up ring of described locking knob contacts with the end face of described plastic tube, inner chamber one end of described connecting sleeve is cylindrical, the other end is the bell mouth shape conical surface, the cylindrical cavity of described connecting sleeve one end is fixedlyed connected with described one-level pipe outer wall, described plastic tube outer wall is made as conical surface, and the outer conical surface of described plastic tube matches with the other end bell mouth shape conical surface of described connecting sleeve, and described plastic tube inner cylindrical surface matches with the external cylindrical surface of described diode.
The back-up ring of described locking knob can be set to multistage step, can correspondingly have a plurality of grooves on the outer wall of described plastic tube, and the multistage step of described locking knob matches with a plurality of grooves of described plastic tube.
Described plastic tube can be made of two semi-round ring shape plastic tubes.
Have several breach on the described plastic tube.
Each adjacent two-stage Guan Junke uses described locking device to lock in the multiple valve.
The utility model is the improvement to multiple valve locking device prior art, has proposed a kind of locking device of pipes at different levels newly.The utility model is to utilize the plastic tube male cone (strobilus masculinus) to match with the inner conical surface of connecting sleeve to lock.For guaranteeing to produce the coupling mechanism force of super large, plastic tube adopts the two-piece type structure, and clamp ring is stuck in the locking knob the inside, promotes plastic tube to top offset by locking knob locking, the outer conical surface of plastic cement and the internal conical surface of connecting sleeve produce mutual extrusion, thereby reach the purpose of locking diode.The ramp type circular cone fixed base of this particular design can absorb that very big load down forms gravity and locks effect from the top is vertical.This locking device has removed gap unnecessary in the structure, has strengthened the tightness of locking back structure, and then has increased stability and the bearing capacity of tripod.
The beneficial effects of the utility model are: than prior art, pipe locking devices at different levels described in the utility model can provide the tight lock power of super large, have improved the reliable lock and the bearing capacity of multiple valve locking device.
