The fixed joint is a hollow pipe, and the movable joint is sleeved in the fixed joint.

The fixed knot is a locking part at one section of the pull cart body, the fixed knot is provided with a locking seat at the bottom surface of the locking part, and the elastic locking assembly is arranged at the locking seat.

The locking seat is provided with an opening which is communicated with the inside, the diameter of the opening is wide outside and narrow inside, the bolt is inserted into the opening and is blocked and connected with limiting movement in the axial direction, the opening is provided with a blocking and connecting part which limits the bolt to be separated from the opening, the spring is arranged between the bolt and the blocking and connecting part, and the pull ring is arranged outside the locking seat.

The movable joint is provided with a plurality of clamping holes which are matched with the bolt in a clamping and limiting way in the length direction.

The utility model has the beneficial effects that: the telescopic adjustable hand buggy provided by the utility model is provided with the special telescopic handle, is convenient to operate and adjust, can be adjusted according to actual needs, is based on the handle design of the parallel car body, is relatively labor-saving and easy to pull goods, and meets the use requirements of personnel transportation.

Drawings

FIG. 1 is a schematic diagram of the structure of the present utility model;

fig. 2 is a schematic view of a partial structure of the present utility model.

Detailed Description

As shown in fig. 1-2, a telescopic handcart comprises a handcart body 1, wherein one end of the handcart body 1 is provided with a handcart handle 2, and the handcart handle 2 is parallel to the directions of the lengths of the handcart body 1. The direction of the handle 2 of the trolley is parallel to the length direction of the trolley, so that the pull force is conveniently applied by a person, and the point is also the basis of a subsequent structure.

The pull handle 2 comprises a movable joint 3 and a fixed joint 4, the fixed joint 4 is fixedly connected with the pull handle body 1, the movable joint 3 is in limiting sleeve joint with the fixed joint 4, and an elastic locking assembly is further arranged between the movable joint 3 and the fixed joint 4. The unlocking and the elastic locking of the pulling are realized through the elastic locking assembly, but the components are required to reach the designated positions.

The elastic locking assembly at least comprises a bolt 5, a spring 6 and a pull ring 7, wherein the bolt 5 and the pull ring 7 are assembled in a linkage mode, the bolt 5 has a reset trend in the linear direction through the spring 6, and the movable joint 3 and the fixed joint 4 are limited to be sleeved and separated through the bolt 5. The fixed joint 4 is a hollow pipe, and the movable joint 3 is sleeved in the fixed joint 4. The fixed knot 4 is a locking part 8 at a section extending out of the trolley body 1, the fixed knot 4 is provided with a locking seat 9 at the bottom surface of the locking part 8, and the elastic locking component is arranged at the locking seat 9. The movable joint 3 is provided with a plurality of clamping holes 10 which are in clamping limit fit with the bolts 5 in the length direction. The bolt 5 is arranged at the opposite outer part of the movable joint 3, and has a trend of being clamped into the clamping hole 10 through the spring 6, so that the movable joint 3 can be locked step by step after being moved.

The locking seat 9 is provided with an opening 11 which is communicated with the inside, the diameter of the opening 11 is wider at the outside and narrower at the inside, the plug pin 5 is inserted into the opening 11 to be blocked and connected with a limiting movement in the axial direction, the opening 11 is provided with a blocking and connecting part 12 which limits the plug pin 5 to be separated from the opening, the spring 6 is arranged between the plug pin 5 and the blocking and connecting part 12, and the pull ring 7 is arranged outside the locking seat 9. The abutment 12 may be a screw cap of a separate construction, mounted by a threaded connection, which is only one implementation and may not be the only limitation.

In the description of the present utility model, it should be noted that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, merely to facilitate description of the present utility model and simplify the description, and do not indicate or imply that the apparatus or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model, while the basic principles, main features, and advantages of the present utility model are shown and described above, and it should be understood by those skilled in the art.
