[0002] Outdoor activities can embrace nature, and their popularity is increasing. Outdoor activities include mountain climbing, party camping, etc. Generally speaking, outdoor activities are usually held in natural places, such as by the river, by the lake, on the mountain or at the foot of the mountain.

[0003] When engaging in outdoor activities, it is necessary to carry a lot of outdoor equipment, such as tents, cooking utensils, dining tables, dining chairs, etc. Since a lot of equipment is carried during outdoor activities, an outdoor trolley has been launched on the market. The trolley includes a storage slot and a handle for the storage slot. The equipment required for outdoor activities is placed in the storage slot for unified transportation, thereby achieving the purpose of easy carrying.

[0004] When a trolley is used outdoors, especially for transportation, it needs to be pushed as a power source. However, most common push rods are telescopic rods, and their telescopic structures are mostly press-type. The force direction is opposite to that of dragging the vehicle body, which is inconvenient to use.

[0005] Therefore, it is necessary to provide a push rod structure suitable for outdoor camp trolleys. Summary of the invention

[0008] A push rod structure suitable for an outdoor camp trolley, comprising a hollow push rod and a pull rod assembly disposed in a push rod cavity;

[0009] The push rod is a telescopic rod, comprising a fixed rod and a movable rod nested with each other, and a handle is arranged at the top of the movable rod;

[0010] The pull rod assembly comprises a pull rod placed in a cavity of the movable rod, a pull handle penetrating the movable rod is provided at the top end of the pull rod, and a latch unit is provided at the bottom end of the pull rod;

[0011] The bolt unit comprises a bolt and an annular seat;

[0012] The latch is T-shaped, a transparent latch groove is provided at the bottom of the pull rod in the horizontal direction, and the latch groove extends in the longitudinal direction, and an inclined slide groove is provided on the side wall of the latch groove, the long handle of the latch is placed in the latch groove horizontally, and at least one end of the long handle of the latch groove is exposed; the short handle of the latch is placed in the slide groove;

[0013] The annular seat sleeve is arranged at the bottom of the pull rod, and the side wall is provided with a through hole corresponding to the long handle of the clamp bolt, and the pull rod sleeve is provided with a spring between the base of the annular seat and the long handle of the clamp bolt;

[0014] The annular seat is fixedly connected to the bottom of the movable rod and is placed inside the fixed rod;

[0015] Along the longitudinal direction, the fixing rod is provided with a plurality of bolt holes corresponding to the clamping bolts.

[0016] The handle is ring-shaped, and the pull handle is placed in the ring of the handle.

[0017] The utility model is beneficial in that:

[0018] The utility model discloses a push rod structure suitable for an outdoor camp trolley. A stretchable pull rod assembly is arranged in a movable rod, and a latch bolt at the bottom is linked by a pull handle. When the pull handle moves upward, the latch bolt moves horizontally and disengages from a bolt hole of a fixed rod. When the pull handle is not subjected to force, under the action of a spring, the latch bolt moves in the opposite direction and is inserted into the bolt hole again, so that the fixed rod and the movable rod are locked.

[0019] The utility model discloses a push rod structure suitable for an outdoor camp trolley, which has a simple structure, conforms to the force direction of a human body, is easy to operate, and has strong practicality and wide applicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] The utility model relates to a push rod structure suitable for an outdoor camp trolley, which is composed of a push rod, a pull rod and a clamping bolt unit.

[0027] The push rod is a telescopic rod, which is composed of a fixed rod 1 and a movable rod 2 which are nested with each other. Preferably, the fixed rod 1 and the movable rod 2 are both hollow rods. Preferably, the movable rod 2 is placed in the cavity of the fixed rod 1. The bottom end of the fixed rod 1 is fixed to the body axis of the trolley.

[0028] The handle 3 is arranged at the top end of the movable rod 2. Preferably, the handle 3 is ring-shaped.

[0029] The pull rod is placed in the cavity of the movable rod 2 , and the top end of the pull rod is fixedly connected to the pull handle 4 . Preferably, the pull handle 4 is placed in the ring of the handle 3 .

[0030] The bolt unit is arranged at the bottom of the pull rod, and the pull rod and the bolt unit constitute a pull rod assembly.

[0031] The latch unit is composed of a latch and an annular seat 9 .

[0032] The latch is T-shaped and consists of a long-handled insertion rod 5 and a short-handled lever 6. A slot 7 is provided at the bottom of the pull rod in the horizontal direction and is transparent to the side wall of the pull rod. The insertion rod 5 is placed horizontally in the slot 7, and the slot 7 extends longitudinally to a certain height, so that the insertion rod 5 can slide up and down in the slot 7. The pull rod is provided with an inclined slide groove 8 on the side wall of the slot 7, and the lever 6 is placed in the slide groove 8. Preferably, the height of the slide groove 8 in the longitudinal direction is the same as the height of the slot 7 in the longitudinal direction.

[0033] The annular seat 9 is sleeved from the bottom end of the pull rod and wraps the card slot 7, and the bottom is sealed. On the inner side wall of the annular seat 9, the pull rod is sleeved with a spring 10, the bottom end of the spring 10 abuts the annular seat 9, and the top end abuts the plug rod 5 of the card bolt.

[0034] The annular seat 9 is placed in the movable rod 2 and fixed to the movable rod 2 by bolts 11. The annular seat 9 and the movable rod 2 are provided with through holes for the insertion rod 5 to penetrate.

[0035] When using,

[0036] Place the bottom of the movable rod 2 in the fixed rod 1, hold the handle 3, and pull the handle 4 with your fingers. The linkage handle 4 rises in the movable rod 2. Since the annular seat 9 is fixed to the movable rod 2, the lever 6 of the bolt slides downward along the slide groove 8, and then the insertion rod 5 slides downward along the slide groove 8. At the same time, the insertion rod 5 moves horizontally, and the end of the insertion rod 5 is disengaged from the bolt hole on the fixed rod 1, so that the movable rod 2 and the fixed rod 1 are in a separated state, and the telescopic operation of the movable rod 2 is performed.

[0037] The movable rod 2 is set to a suitable height, and the handle 4 is released. Under the elastic force of the spring 10, the latch moves in the opposite direction, so that the end of the insertion rod 5 is inserted into the corresponding bolt hole again, so that the movable rod 2 and the fixed rod 1 are in a locked state.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the above embodiments do not limit the utility model in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the utility model.
