[0005] Furthermore, a groove is formed on a side edge of one end portion of the plug-in unit close to the second connecting rod, and a cylindrical boss is formed in the groove.
[0006] Furthermore, a through hole is provided in the middle of the boss.
[0007] Furthermore, the locking member includes an end cover and a fixing column, one end of the fixing column is arranged in the middle of the end cover, and the other end of the fixing column is inserted into the through hole.
[0008] Furthermore, a limiting notch is provided on a side of the groove, and a positioning block is provided on a side of the end cover, and the positioning block is located in the limiting notch.
[0009] Furthermore, the spring is sleeved on the fixing column, one end of the spring is connected to the boss, and the other end is connected to the end cover.
[0010] Furthermore, one end of the connector close to the plug-in is open, and the plug-in can be inserted into the connector.
[0011] Furthermore, the plug-in and the connecting piece are fixed to the first connecting rod and the second connecting rod respectively by rivets.
[0012] Through the above scheme, the utility model has at least the following advantages: the connecting rod locking mechanism has a simple structure, ingenious design, low cost, and easy disassembly and assembly. When installed in the width direction of the camp cart, it can not only play a supporting role, but also when the camp cart needs to be folded, the mechanism can be unlocked and disassembled, so that the camp cart can be folded in the width direction without restraint, thereby reducing the volume of the camp cart after folding, making it convenient to store and carry the camp cart.
[0013] The above description is only an overview of the technical solution of the utility model. In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the following is a detailed description of the preferred embodiments of the utility model in conjunction with the accompanying drawings.

[0020] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0021] Embodiment: A connecting rod locking mechanism comprises a first connecting rod 5, a second connecting rod 6, a plug-in 1, a locking member 2, a spring 3 and a connecting member 4. The first connecting rod and the second connecting rod are independently arranged. The plug-in is fixed to one end of the first connecting rod close to the second connecting rod, the connecting member is fixed to one end of the second connecting rod close to the first connecting rod, the locking member is connected to the plug-in through the spring, and the connecting member is provided with a locking hole 7 for the locking member to penetrate. The first connecting rod and the second connecting rod are respectively hinged in the width direction of the camp cart.
[0022] A groove 11 is formed on the side of one end of the plug-in unit close to the second connecting rod, and a cylindrical boss 12 is formed in the groove.
[0023] A through hole 13 is provided in the middle of the boss.
[0024] The locking member includes an end cover 21 and a fixing column 22, one end of the fixing column is arranged in the middle of the end cover, and the other end of the fixing column is inserted into the through hole.
[0025] The side of the groove is provided with a limiting notch 14, and the side of the end cover is provided with a positioning block 23, and the positioning block is located in the limiting notch. The design of the positioning block and the limiting notch can prevent the locking member from shaking or deflecting during the pressing process.
[0026] The spring is sleeved on the fixing column, one end of the spring is connected to the boss, and the other end is connected to the end cover.
[0027] One end of the connector close to the plug-in is open, and the plug-in can be inserted into the connector.
[0028] The plug-in unit and the connecting member are fixed to the first connecting rod and the second connecting rod respectively by rivets.
[0029] The locking state of the connecting rod locking mechanism is as follows: the spring is in a natural state, the plug-in is inserted into the connecting piece, the locking piece penetrates into the locking hole, and the first connecting rod and the second connecting rod are in a locked state.
[0030] The unlocking method of the connecting rod locking mechanism is: press the locking piece by hand, the spring is in a squeezed state, so that the locking piece is disengaged from the locking hole to achieve unlocking. Pull the first connecting rod to pull the plug out of the connecting piece, at this time the first connecting rod and the second connecting rod are separated, the camp cart is no longer constrained in the width direction, so that the camp cart can be folded not only in the length direction but also in the width direction, so that the camp cart can be completely folded, thereby reducing the volume of the camp cart after folding, making the camp cart convenient to store and carry.
[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
