Abstract
The utility model discloses a pipe slide locking structure for a baby stroller. The pipe slide locking structure comprises a first pipe and a second pipe which is inserted into the first pipe and can stretch relative to the first pipe, a connection part is arranged at the extending-out end, relative to the second pipe, of the first pipe, a locking wrench is in pin joint with one side of the connection part, an axially-extending groove portion is arranged at the position, relative to the locking wrench, of the second pipe, an opening corresponding to the groove portion is arranged on the connection part, and a protrusion portion of the locking wrench can extend into the opening. The first pipe can lock or unlock the second pipe sliding in the first pipe through the locking wrench on a rotary connection part. The pipe slide locking structure for the baby stroller is simple in structure convenient to operate and capable of saving time and labor in use.
Description
Technical field
The utility model relates to a kind of pipe fitting slide lock structure of doll carriage.
Background technology
In the prior art, some doll carriage can adopt the flexible relatively structure of two pipe fittings for the volume that dwindles better after folding, but the latch-up structure that existing pipe fitting stretches is comparatively complicated, and operating wastes time and energy.
Summary of the invention
The utility model purpose is: the pipe fitting slide lock structure that a kind of doll carriage is provided, its first pipe fitting locks or release second pipe fitting that slides in it by the locking spanner on the rotating connector, simple in structure, easy to operate, it is time saving and energy saving to use.
The technical solution of the utility model is: a kind of pipe fitting slide lock structure of doll carriage, comprise first pipe fitting and be inserted in first pipe fitting, can relative first pipe fitting second flexible pipe fitting, the external part of relative second pipe fitting of described first pipe fitting is provided with attaching parts, one side of this attaching parts is connected with the locking spanner, the position that described second pipe fitting locks spanner relatively is provided with axially extended concave part, described attaching parts is provided with the opening that lug boss corresponding with concave part and confession locking spanner stretches into, above-mentioned locking spanner has two control positioies of the locking and unlocking, when the locking spanner is in the locking mode of operation, the lug boss of locking spanner passes opening and holds out against the concave part of second pipe fitting, second pipe fitting is with attaching parts and first pipe fitting is relative locks, when the locking spanner is in the release mode of operation, the lug boss of locking spanner departs from opening and unclamps second pipe fitting, second pipe fitting can relative first pipe fitting and attaching parts be free to slide.
The concrete connection mode of above-mentioned attaching parts and first pipe fitting is: described attaching parts is cyclic structure, it has negative thread, the end that described first pipe fitting is connected with attaching parts is provided with outside thread, and described attaching parts and first pipe fitting are realized being connected and fixed between the two by negative thread and externally threaded threaded.
The utility model has the advantages that:
1, first pipe fitting of the present utility model locks or release second pipe fitting that slides in it by the locking spanner on the rotating connector, and is simple in structure, easy to operate, and it is time saving and energy saving to use.
, attaching parts and first pipe fitting are realized being connected and fixed between the two by negative thread and externally threaded threaded in the utility model, this connection mode not only is convenient to processing but also is easy to assembling and part replacement.

The specific embodiment
Embodiment: as shown in Figures 1 to 4, a kind of pipe fitting slide lock structure of doll carriage, comprise first pipe fitting 1 and be inserted in first pipe fitting 1, can be relative the second flexible pipe fitting 2 of first pipe fitting 1, the external part of described first pipe fitting, 1 relative second pipe fitting 2 is provided with attaching parts 3, one side of this attaching parts 3 is connected with locking spanner 4, described second pipe fitting 2 is provided with axially extended concave part 21 in the position of locking spanner 4 relatively, described attaching parts 3 is provided with the opening 31 that stretches into concave part 21 lug bosses 41 corresponding and confession locking spanner 4, above-mentioned locking spanner 4 has two control positioies of the locking and unlocking, when locking spanner 4 is in the locking mode of operation, the lug boss 41 of locking spanner 4 passes opening 31 and holds out against the concave part 21 of second pipe fitting 2, second pipe fitting 2 and attaching parts 3 and the 1 relative locking of first pipe fitting, when locking spanner 4 is in the release mode of operation, the lug boss 41 of locking spanner 4 depart from opening 31 and unclamp second pipe fitting, 2, the second pipe fittings 2 can relative first pipe fitting 1 and attaching parts 3 be free to slide.
The concrete connection mode of above-mentioned attaching parts 3 and first pipe fitting 1 is: described attaching parts 3 is cyclic structure, it has negative thread 32, the end that described first pipe fitting 1 is connected with attaching parts 3 is provided with outside thread 11, and described attaching parts 3 and first pipe fitting 1 threaded by negative thread 32 and outside thread 11 realizes being connected and fixed between the two.
First pipe fitting 1 of the present utility model locks or release second pipe fitting 2 that slides in it by the locking spanner 4 on the rotating connector 3, and simple in structure, easy to operate, it is time saving and energy saving to use.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.In addition to the implementation, the utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
