The beneficial effects of the invention are as follows：
It can be seen that in elastic mechanism provided by the invention, spring is arranged between top mounting seat and bottom mounting seat, is slided
Part can be slidably matched relative to the slideway of bottom mounting seat.Spring is set on sliding part and bottom mounting seat.The elastic mechanism
During work, the flexible of spring can slide progress with the sliding part that it is arranged in slideway, and this can improve elasticity
The flexible stability of mechanism, avoids spring that larger deformation occurs.Meanwhile the sealing ring on the top of slideway can sealing chute,
Avoid dust from entering slideway, and then the service life of elastic mechanism can be improved.
Brief description of the drawings
Fig. 1 is the structural representation of the elastic mechanism of CPR medical model provided in an embodiment of the present invention.
Embodiment
The present invention is described in further detail below by specific embodiment and with reference to accompanying drawing.
Fig. 1 is refer to, the embodiment of the present invention provides a kind of elastic mechanism of the medical model of CPR.The elastic mechanism bag
Include top mounting seat 10, bottom mounting seat 20, spring 30 and sliding part 40.
Bottom mounting seat 20 is provided with slideway 201, and top mounting seat 10 is fixed on the top of sliding part 40.Sliding part 40
Bottom is extended in slideway 201, and is slidably matched with slideway 201.
Spring 30 is set on sliding part 40 and bottom mounting seat 20, the both ends of spring 30 respectively with top mounting seat 10 and
The confined planes of bottom mounting seat 20 offset cooperation.
The top of slideway 201 is provided with sealing ring 50.Sealing ring 50 is sealingly disposed in the top of slideway 201, and with slip
Part 40 forms and is slidingly sealed structure.
In elastic mechanism provided in an embodiment of the present invention, spring 30 be arranged on top mounting seat 10 and bottom mounting seat 20 it
Between, sliding part 40 can be slidably matched relative to the slideway 201 of bottom mounting seat 20.Spring 30 is set in sliding part 40 and bottom peace
Fill on seat 20.For the elastic mechanism during work, the flexible of spring 30 can be as the sliding part 40 that it is arranged be in slideway 201
