Description
Technical field
The utility model relates to photographic goods foot rest locking device, especially a kind of photographic tripod telescopic leg pipe locking device.
Background technique
At present, the photographic tripod of on market, selling, the locking of its first pipe fitting and second pipe fitting is to cooperate and realize by one-time formed fastener or the screw tightening aluminum casting pulled.From actual practical effect, though this structural type is simple, but the locking between the tripod pin pipe is also insecure, bearing capacity is not enough, the lighter can't normally photograph the photographer, weight person breaks camera owing to the stressed uneven horizontal stroke of tripod falls down camera and tripod, brings a lot of troubles for practical person.
The model utility content
Technical problem to be solved of the present utility model is exactly that a kind of new photographic tripod pipe fitting locking device that stretches is being provided with the deficiency that exists at prior art, and it can make the connection between the pipe fitting more tight, locks more firm.
The technological scheme that the utility model is taked is, a kind of novel foot rest locking device, and its structure comprises swivel nut, fastening piece in first pipe fitting, second pipe fitting, locking external thread sleeve, the locking; Described locking external thread sleeve is provided with groove and screw thread, and fastening piece is between second pipe fitting and the locking external thread sleeve, and fastening piece is provided with in the groove that convex annular axle and protruding axle be embedded in the locking external thread sleeve and adapts with it.
Swivel nut is arranged between fastening piece, first pipe fitting and the locking external thread sleeve in the described locking, has screw thread to overlap with locking external thread sleeve screw thread in the locking on the swivel nut, pushes down first pipe fitting.
Protruding axle on the described fastening piece embeds the locking external thread sleeve, and the fastening piece inner plane is close to second pipe fitting.
A kind of novel foot rest locking device of the present utility model compared with prior art has following beneficial effect:
The utility model comprise be positioned at first pipe fitting on the locking swivel nut and the fastening piece on second pipe fitting, swivel nut overlaps with locking external thread sleeve screw thread in the locking, fastening piece is protruding axle shape, the external thread sleeve groove is locked in the protruding axle embedding of fastening piece.Fastening piece be and second pipe fitting and locking between the swivel nut.Driving the interior swivel nut of fastening piece second pipe fitting and locking during the rotational lock external thread sleeve directly pushes and spreading, firmly lock second pipe fitting, otherwise then unclamp second pipe fitting, thereby improve the bearing capacity of tripod, the operation of photographing normally in the time of more making things convenient for the photographer on tripod, to hang with weight.
