Description

Two-way stretch handle bar

technical field

A two-way stretch handle bar.

Background technique

Stretchable handle bars are widely used in portable suitcases, similar to tripods and other portable tools, and have the characteristics of making life easier, improving efficiency, being beautiful and practical, and are widely welcomed by people.

Although the previous stretchable handle bar has the characteristics of convenient life, improved efficiency, beautiful and practical, but because it is only stretched in one direction, it cannot take into account both the stretched length and the original volume, and cannot meet the needs of users when using it. Long, high-efficiency use requirements that the volume is small enough to save.

Contents of the invention

The purpose of this utility model is to make it not only have the characteristics of the previous one-way handle bar, which is convenient for life, improve efficiency, beautiful and practical through the design of the two-way stretching handle bar, but also meet the needs of the user when the length is long enough when using it, and when it is stored. The volume is small enough for high-efficiency use requirements.

The utility model is composed of two-way coil spring assembly, No. 1 pipe, No. 2 pipe, No. 3 pipe, No. 1 pipe handle and No. 2 pipe handle. At the bottom of the inner side of No. 1 tube, the ascending coil spring is fixed on the top of the inner side of No. 3 tube. The handle of No. 1 tube is connected to No. 2 tube. The head is provided with connecting bolts.

The two-way coil spring assembly is composed of a fixed connector and a two-way coil spring. The fixed connector is composed of a left and right connector. The connector is equipped with a coil spring fixing cabin, an upper coil spring outlet, a lower coil spring outlet, and an upper coil spring outlet guide connection. Platform; the two-way coil spring is set in the coil spring fixed cabin through the coil spring shaft, the upper coil spring is drawn from the upper coil spring outlet, and connected to the No. 3 pipe through the guiding connection platform, the lower coil spring is drawn from the lower coil spring outlet, The spring connection end is fixed at the bottom of the inner side of the No. 1 pipe; after the left and right connectors are fastened, they are fixedly connected with the front and rear connecting columns.

When using the utility model, first connect the equipment to be used on the connecting bolt at the end of the No. 3 tube. When necessary, hold the No. 1 tube handle and the No. 2 tube handle with both hands, and stretch in two directions at the same time, and the two-way coil spring The connected No. 1 tube is pulled out downwards, and the No. 2 tube is exposed to form a section of the applied length of the handle bar; the No. 3 tube is pushed forward by the top extension force of the two-way coil spring upward coil spring to form a part of the handle bar. Another application length. At this point, the stretched state of the present invention can be used by locking the pin hole. When not in use, you only need to loosen the locking pin, and the No. 1 tube and No. 3 tube will automatically reset and close under the action of the return elastic force of the two-way coil spring.

The utility model is exquisite in structure, reasonable in design, convenient to use and carry, can meet the high-efficiency requirements of the user that the length is long enough for use, and the volume is small enough for storage, and has practical practical value and huge market demand.
