Abstract
The utility model is a mechanical braking universal joint belonging to the scope of connecting hinges. The utility model can be divided into the screw type structure and the hydraulic piston structure due to different force-applying structures. The universal spherical cavity which consists of a joint shell and a housing lid is wrapped up by the concave spherical lock and the housing lid in the shell, and the force-applying bar with a handle provided on one end passes through the bottom surface of the shell to press on the gasket on the back of the lock. When the straight bar or the wheel disc handle is turned or the hydraulic device is started, the screw or the force-applying bar of the hydraulic piston pushes the concave spherical lock to prop up the universal sphere tightly; on the contrary, after the applied force is loosed, the lock looses to release the tightly locked universal sphere. The joint of the utility model can be fixed in any direction, thus to avoid changing position under the effect of the random external force, and has the advantages of convenience in operation and wide application in medical equipment and other equipment.
Description
Technical field
The utility model belongs to and connects the hinge scope, particularly a kind of cardon link of mechanical force braking.
Background technique
The cardon link use is extensive, machinery, on the electrical products everywhere as seen, but they are fixed on a certain position by the frictional force of being scheduled to, very insecure, be subjected to some external force slightly, the direction of fixed block just can change.Therefore ask for something is fixedly secured in a certain position, the joint that needs to change at any time direction simultaneously again is very disadvantageous.
Summary of the invention
The purpose of this utility model provides a kind of cardon link of mechanical force system, it is characterized in that: joint housing 3 and housing lid 2 are formed the univesal sphere cavity, in housing 3, univesal sphere 1 is encased by concave spherical surface locking block 4 and housing lid 2, be connected with stationary axle 5 on the univesal sphere, pad 6 of locking block 4 back side pads, force application rod 7 passes housing 3 bottom surfaces and is pressed on the pad 6, and force application rod 7 terminations are equipped with swing handle 8.
Described swing handle is straight-bar or wheel disc.
Described force application rod is bolt or hydraulic piston and electronic scroll bar.
The interior circular diameter that described locking block and housing lid are formed mates with the univesal sphere diameter, and univesal sphere and housing lid 2,4 two parts of locking block can be with metal of the same race or different metals (can increase frictional force).
The beneficial effects of the utility model are that its joint can be fixed in any direction, can not make change in location because of influenced by external force after fixing, and are easy to operate, wide scope on medical treatment or other equipment.
Description of drawings
Fig. 1 is the cardon link structural representation of rotary handle type braking.
Fig. 2 is the cardon link structural representation of hydraulic piston braking.
Embodiment
The utility model is a kind of cardon link of mechanical force braking.Because of its force application structure difference is divided into screw type and two kinds of structures of hydraulic piston.Figure 1 shows that the cardon link structural representation of screw type braking.In Fig. 1, joint housing 3 and housing lid 2 are formed the univesal sphere cavity, in housing 3, univesal sphere 1 is encased by crescent shape concave spherical surface locking block 4 and housing lid 2, locking block 4 back side pads one pad 6, force application rod 7 passes housing 3 bottom surfaces and is pressed on the pad 6, swing handle 8 is installed in force application rod 7 terminations, when the swing handle 8 of rotation straight-bar or Wheel-type or primer fluid pressure device, hold out against univesal sphere 1 for the force application rod 7 of bolt or hydraulic piston promotes crescent shape concave spherical surface locking blocks 4, thereby locked the stationary axle 5 that links to each other with univesal sphere.Rotating straight-bar or wheel disc can be at arbitrary locking position univesal sphere and connected functional part.
Interior circular diameter that described locking block and housing lid are formed and univesal sphere diameter coupling.
Figure 2 shows that the cardon link structural representation of hydraulic piston braking.Different with Fig. 1 is force application rod 7 is not bolt but hydraulic piston 10, piston is in piston cylinder 9.
