Specific embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by specific embodiment.
Fig. 1, Fig. 2 and Fig. 4 are the structure of the Medical hanging bridge slide brake apparatus that the specific embodiment of the invention provides respectively
Schematic diagram, sectional view and scheme of installation.
A kind of Medical hanging bridge slide brake apparatus, it possesses cylinder barrel 1 and cylinder core 2.
The cylindrical cylindrical shape of cylinder barrel 1, one end is open end, and other end is Closed End, and cylinder core 2 is from opening
In mouth end face insertion cylinder barrel 1, it is slidably matched with cylinder barrel 1, Closed End center is provided with inlet suction port 7.
Cylinder core 2 includes round platform piston 3 and frictional slip part, and frictional slip part includes friction pad 5 and round platform groove walls 6,
Friction pad 5 upper surface is provided with a plurality of semicircle friction groove 8, semicircle friction groove 8 be beneficial to increase in braking procedure brake apparatus with
Frictional force between orbital plane, strengthens braking effect, semicircle friction groove 8 can also be other forms, such as triangular groove；Rub
Scrubbing pad 5 and round platform groove walls 6 are one of the forming, integrally formed globality and the fastness that can effectively strengthen component, further, it is contemplated that
Differ to friction pad 5 and round platform groove walls 6 job specification and environment it is also possible to consider friction pad 5 and round platform groove walls 6 using not
Form with material bonding so as to be more suitable for respective working environment.
