Abstract

Cog belongs to machinery. Its characterized in that: specifically by joint no. 1, joint no. 2 is constituteed with the hand wheel, the one side in joint no. 1 and joint no. 2 has the outstanding tooth of round respectively, joint no. 1, and it is the same that the number of teeth is gone up in joint no. 2, and the tooth and the joint no. 2 in joint no. 1 correspond the middle recess embedding meshing of two teeth, the back is meshed through hand wheel locking through the embedding in two joints, the other end in joint no. 1 and joint no. 2 is the hollow cylinder of ability and thick stick body coupling. The utility model discloses can realize combining with the nimble of the thick stick body to can stably connect. For example use the stretcher design and go up the adoption the utility model discloses connect, will make the stretcher can have multiple variant.

Description

Joint gear

Technical field

This joint gear belongs to mechanical field.

Background technology

In the joint with the combination of thick stick body, there is no the joint that can combine flexibly and be stably connected with in the market.

Summary of the invention

Joint gear, it is characterised in that: by joint one, joint two and handwheel composition；The one side in joint one and joint two has the tooth that a circle is prominent, joint one respectively, and on joint two, the number of teeth is identical, and the tooth in joint one two tooth intermediate recess places corresponding to joint two embed engagement；Joint one and joint two are locked by handwheel after embedding engagement, and the other end in joint one and joint two is the hollow cylinder that can connect with thick stick body.

The gear structure in joint must ensure that two parts thick stick body that it connects can rotate against, and can locking positioning after rotation.

This utility model can realize the flexible combination with thick stick body, and can be stably connected with.Such as it is applied to stretcher design upper employing this utility model to connect, stretcher will be made to have multiple variant.

Detailed description of the invention

Portable multi-function Rescue stretcher, including main part and supporting construction, it is characterised in that:

Main part is divided into three parts: the first main part and the second main part symmetric design, and connects into as a whole by two middle thick sticks；First main part concrete structure is: being connected one end that the one end in a joint overlaps 6 with threeway, this joint other end is connected with thick stick, is attached separately on two symmetrical thick sticks by two two-way sets, and two two-way sets are connected by cross bar 5, and stretcher main part completes.The radical of main part thick stick is 4, and the number of threeway set is 4；

Supporting construction: the joint one that 6 times end interfaces and a joint gear are overlapped in threeway is connected, the joint two in this joint is connected with one end of supporting lever 7, the other end of supporting lever 7 is connected with even wheel bar 8 by another joint, even wheel bar 8 is connected with universal wheel 9, supporting lever 7 central authorities buckle two-way set 4, and two two-way sets are connected by cross bar 5；Such supporting construction has 4, symmetrical.

Joint gear, by joint one, joint two and handwheel composition；The one side in joint one and joint two has the tooth that a circle is prominent, joint one respectively, and on joint two, the number of teeth is identical, and the tooth in joint one two tooth intermediate recess places corresponding to joint two embed engagement；Joint one and joint two are locked by handwheel after embedding engagement, and the other end in joint one and joint two is the hollow cylinder that can connect with thick stick body.

Apply in the design of stretcher, and utilize the gear engagement of joint gear that stretcher is fixed.Fig. 4 is stretcher schematic diagram, and for operating-table state, because have employed joint gear can become knapsack state, wheelchair state, double ladder state, stretcher (hands is lifted) uses state, go-cart state, long scalariform state.

This product design mechanism is simple, and operable degree height, its modular construction is applicable to batch production, has very wide market prospect.
