Description

A locking mechanism for tripod carbon fiber legs

technical field

The utility model relates to a locking mechanism for tripod legs, in particular to a locking mechanism for tripod carbon fiber legs.

Background technique

Traditional tripod legs are mainly metal legs. Due to the high density of the metal material used in the metal legs, the overall mass of the tripod is relatively large. At the same time, due to the high thermal expansion coefficient of the metal material used, the accuracy of the measuring instrument will be affected during precision measurement. Therefore, in order to meet the requirements of some special occasions, people have designed carbon fiber outriggers. Compared with metal materials, carbon fiber materials are less dense and have a lower coefficient of thermal expansion. Therefore, compared with metal legs, carbon fiber legs reduce the overall mass of the tripod and can guarantee the accuracy of the measuring instrument when taking precise measurements. Under the existing technical conditions, there are many kinds of locking mechanisms for tripod legs, some of which use the friction force of the inner and outer sleeves to lock, and some of them use mechanical mechanisms for locking. However, practice has shown that the locking mechanism of the existing tripod legs is only suitable for metal legs, but not for carbon fiber legs due to its own structural limitations. Specifically, when using the locking mechanism of the existing tripod legs to lock the carbon fiber legs, it is necessary to carry out secondary machining on the carbon fiber legs, and once the carbon fiber material used in the carbon fiber legs is processed , its mechanical properties will be reduced, thereby affecting the overall stability of the tripod. Based on this, it is necessary to invent a brand new locking mechanism for tripod legs to solve the problem that the existing locking mechanism for tripod legs is not suitable for carbon fiber legs.

Contents of the invention

In order to solve the problem that the locking mechanism of the existing tripod legs is not suitable for the carbon fiber legs, the utility model provides a locking mechanism for the carbon fiber legs of the tripod.

The utility model is realized by adopting the following technical scheme: a locking mechanism for the carbon fiber legs of a tripod, including a carbon fiber inner cylinder, a carbon fiber outer cylinder, a metal connecting cylinder, a metal rack, a shaft seat, a lock shaft, a lock Body, lock hole, spring groove, locking spring; among them, the carbon fiber outer cylinder is slid and sleeved on the rear outer side of the carbon fiber inner cylinder along the axial direction; the rear part of the metal connecting cylinder is fixedly sleeved on the front outer side of the carbon fiber outer cylinder; The front part of the metal connecting cylinder is sleeved on the outside of the carbon fiber inner cylinder; the back of the metal rack is fixed axially on the outer wall of the carbon fiber inner cylinder; the rotating shaft seat is fixed on the rear outer wall of the metal connecting cylinder; the locking body passes through the locking shaft Supported on the rotating shaft seat; the lock hole is opened on the front wall of the metal connecting cylinder; the locking teeth of the lock body pass through the lock hole and engage on the metal rack; the spring groove is opened on the front outer wall of the metal connecting cylinder; One end of the lock spring is fixed on the bottom wall of the spring groove, and the other end of the lock spring is fixed on the front lower wall of the lock body.

When in use, the carbon fiber inner cylinder, the carbon fiber outer cylinder and the metal connecting cylinder together form the carbon fiber outrigger. The specific use process includes: 1. When locking the carbon fiber outrigger, the locking teeth of the locking body are tightly engaged with the metal rack under the tension of the locking spring. At this time, the carbon fiber inner cylinder and the carbon fiber outer cylinder Relative movement is not possible, enabling the locking of the carbon fiber outriggers. 2. When stretching the carbon fiber outrigger, press the rear upper wall of the locking body, and the front of the locking body overcomes the tension of the locking spring to tilt up, and drives the locking teeth to separate from the metal rack. Twitch or push the carbon fiber inner cylinder from time to time, and the relative movement between the carbon fiber inner cylinder and the carbon fiber outer cylinder will realize the expansion and contraction of the carbon fiber outriggers. Based on the above process, compared with the locking mechanism of the existing tripod legs, a locking mechanism for tripod carbon fiber legs according to the utility model has the following advantages by organically combining carbon fiber materials with metal materials : when adopting a kind of locking mechanism that is used for tripod carbon fiber leg described in the utility model to lock carbon fiber leg, need not carry out secondary mechanical processing to carbon fiber leg, just can lock carbon fiber leg , thereby effectively ensuring the mechanical properties of the carbon fiber legs, effectively ensuring the overall stability of the tripod, thereby effectively solving the problem that the locking mechanism of the existing tripod legs is not suitable for carbon fiber legs.

The utility model has reasonable structure and ingenious design, effectively solves the problem that the locking mechanism of the existing tripod legs is not suitable for the carbon fiber legs, and is suitable for the carbon fiber legs of the tripod.
