Disclosure of Invention
The utility model aims to provide an assembled frame which is convenient to process, quick to install and accurate in positioning aiming at the defects of a welded frame in the prior art.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides an equipment truck, includes frame pipe fitting, its characterized in that: the frame pipes are fixedly connected together through detachable connecting pieces. The frame pipe fittings are connected together through the detachable connecting piece, welding processing is not needed, the production efficiency is greatly improved, and the structure of the connecting piece can also ensure the consistency of products.
It is further characterized in that: the frame pipe fitting includes upper tube, well pipe, low tube, goes up the breeches pipe and the breeches pipe down. Adopt traditional bicycle or electric bicycle's structure, simple structure, the equipment of being convenient for.
Further: one end of the upper pipe is connected with one end of the lower pipe through a head pipe joint; the other end of the upper pipe, one end of the middle pipe and the upper fork pipe are connected to a middle pipe joint together; the other end of the lower pipe, the other end of the middle pipe and one end of the lower fork pipe are connected to the five-way joint together. The frame is connected into a whole through the head pipe joint, the middle pipe joint and the five-way joint to form a strong supporting structure, so that the strength of the vehicle body is ensured.
Further: the upper fork pipe comprises a left upper fork pipe and a right upper fork pipe, and one end of the left upper fork pipe and one end of the right upper fork pipe are respectively connected to the middle pipe joint; the lower fork tube comprises a left lower fork tube and a right lower fork tube, and one end of the left lower fork tube and one end of the right lower fork tube are respectively connected to the five-way joint; the other ends of the left upper fork tube and the left lower fork tube are connected to the left hook claw together, and the other ends of the right upper fork tube and the right lower fork tube are connected to the right hook claw together. The upper fork tube and the lower fork tube are of split assembly structures, welding processes are further reduced, the machining difficulty of the frame is reduced, production efficiency is improved, and assembling pleasure is increased.
Preferably: the left upper fork tube and the right upper fork tube are connected with the connecting piece in a fixed mode through inserting and connecting modes, and are locked through screws. The mode of splicing and screw fixing is adopted, so that the quick assembly of the fork tube is facilitated.
Preferably: two ends of the upper pipe and the lower pipe are fixedly connected with the connecting piece in an inserting mode and locked by screws; one end of the middle pipe is sleeved in the middle pipe joint and locked through a screw, and the other end of the middle pipe is in threaded connection with the five-way joint. Adopt grafting and the fixed mode of screw, can reduce the degree of difficulty of equipment, improve the packaging efficiency, also be guaranteed to the intensity of frame simultaneously.
Preferably: and a battery is arranged in the lower pipe. For an electric bicycle or an electric moped, the battery is arranged in the lower pipe, so that the space of the pipe fitting is effectively utilized, and the frame is simpler. Meanwhile, the gravity center of the frame is lowered due to the installation position of the battery.
The utility model adopts the connecting piece to connect all the pipe fittings of the frame into a whole, and welding is not needed in the production process, thereby greatly improving the production efficiency. The pipe fittings are connected through the connecting piece, and the installation consistency of the frame can be ensured at the same time. Adopt assembled frame, also can give the user with the assembly process, let the user just can be quick assembly whole car through simple instrument, enjoy the enjoyment of manual equipment. In addition, the assembled frame can be packaged and transported through parts, so that the size of the package is greatly reduced, and the transportation is convenient.
