Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-4, the present embodiment provides a vibration isolator with a protection function, which includes a base 1, a sleeve 2 is fixedly installed above the base 1, a core shaft is disposed inside the sleeve 2, and a compression spring is sleeved on an outer wall of the core shaft.
The through-hole has been seted up at base 1 middle part, and the through-hole is inside to be provided with the sucking disc 11 that adsorbs mutually with the workstation, through promoting the adsorption effect between sucking disc 11 and the workstation, promotes the stability between base 1 and the workstation, and then guarantees that sleeve 2 can not produce and empty to avoid the isolator to take place to empty, influence the result of use.
The middle part of the sleeve 2 is fixedly provided with the partition plate 4, the compression chamber 41 is formed between the lower surface of the partition plate 4 and the upper surface of the base 1, the air inside the compression chamber 41 is extruded, so that the gas pressure inside the compression chamber 41 is increased, certain pressing force is generated on the sucker 11, the adsorption effect of the sucker 11 and a table top is improved, and the purpose that the vibration isolator is not prone to toppling is achieved.
A plurality of guard plates 3 are slidably mounted on the outer wall of the sleeve 2 to protect the sleeve 2, so that the outer wall of the sleeve 2 cannot be influenced by external factors to deform, and the use effect of the mandrel inside the sleeve 2 and the compression spring cannot be influenced.
One side middle part fixed mounting that guard plate 3 is close to sleeve 2 has the piece 31 of promotion, the one end slidable mounting that the guard plate 3 was kept away from to the piece 31 is in the inside of compression chamber 41, with guard plate 3 and compression chamber 41 intercommunication together, when guard plate 3 receives external effort, can drive the piece 31 of promotion and slide to one side that is close to compression chamber 41, and then make and promote the piece 31 and compress the inside air of compression chamber 41, make to be connected more closely between base 1 and the workstation, and then reach the difficult mesh of empting of isolator.
And because the compressed gas needs to consume certain kinetic energy, the impact force borne by the protection plate 3 can be reduced, and the sleeve 2 is not easy to deform.
In order to further promote the compression effect of promotion piece 31 to the inside gas of compression chamber 41, improve the adsorption effect of sucking disc 11 to the workstation with this, sleeve 2 outer wall is offered and is used for the installation to promote the recess 21 of piece 31, it is protruding to promote the one end that piece 31 kept away from guard plate 3, the increase promotes the area of contact of piece 31 tip and gas, and then promote the compression effect to gas, and guarantee that the inside gas of compression chamber 41 is difficult for escaping, thereby compression chamber 41's leakproofness has been guaranteed.
Wherein, promote the piece 31 tip and set up to quadrangular frustum pyramid type structure, further increase the gaseous promotion effect, and can guarantee to promote the piece 31 and can not break away from compression chamber 41 is inside.
In order to further promote the protection effect of guard plate 3, the inner wall fixed mounting of guard plate 3 has stopper 32 that the symmetry set up, and the mounting groove 22 that is used for stopper 32 activity is offered to 2 outer walls of sleeve, through the inside resistance of mounting groove 22, reduces external impact force to guard plate 3.
The inside symmetry of mounting groove 22 is provided with arc shell fragment 221, and two arc shell fragments 221 provide one all the time to stopper 32 along being close to the gliding power of 3 directions of guard plate, and then guard plate 3 can receive great resistance when sliding to sleeve 2 is inside to this reduces the impact force that the external world caused guard plate 3.
In order to ensure that the protection plates 3 cannot touch the outer wall of the sleeve 2 when being subjected to large impact force, the outer wall of the sleeve 2 is fixedly provided with a gasket 23, the gasket 23 is positioned between two adjacent protection plates 3, and the gasket 23 can adopt a damping pad made of rubber in the prior art.
When external impact force is too big, guard plate 3 and packing ring 23 laminate mutually, and packing ring 23 both had played the effect to the protection of 2 outer walls of sleeve, also can play the effect of buffering guard plate 3, carries out the reduction once more to external impact force.
In order to promote the protection effect to sleeve 2, guard plate 3 sets up to the arc structure, and the increase is to sleeve 2's protection scope, and then promotes the protection effect to sleeve 2.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
