Abstract

The utility model discloses a support pad which comprises an elastic main body. One side of the elastic main body is a support contact surface, and the other side of the elastic main body is a mounting surface. The elastic main body is provided with an air chamber which is opened from the middle part of the mounting surface and extends to the support contact surface. The elastic main body is further provided with an exhaust passage which extends from the side wall of the air chamber to the outer edge of the elastic main body and is communicated with the air chamber and the elastic main body. By means of the arrangement of the air chamber and the exhaust passage on the elastic main body, support height of the support pad can be changed by means of extrusion of air inside the air chamber, so that instrument and equipment supported by the support pad is adjusted to keep level.

Traditional foot pad generally all is the very simple closed square of structure or disk.When instrument and equipment was placed on the surface of out-of-flatness or inclination, this foot pad can not be used for adjusting the best that highly makes instrument and equipment maintenance level and use state.

The model utility content

Based on this, be necessary to provide a kind of and can be used for the Support cushion that bearing height is adjusted in the instrument and equipment bottom surface.

A kind of Support cushion, comprise elastic body, the one side of described elastic body is for supporting surface of contact, the another side of described elastic body is attachment face, elastic body offers from attachment face intermediate portion opening and to the air chamber that supports the surface of contact extension, also offers the exhaust passage to the extension of elastic body outer rim and perforation from gas chamber sidewall on the described elastic body.

Among embodiment, described support surface of contact is cambered surface therein.

Among embodiment, described exhaust passage is air vent therein.

Among embodiment, described exhaust passage is exhaust hole therein.

Among embodiment, the quantity of described exhaust passage is more than 2 therein.

Among embodiment, described elastic body integral body is discoid therein.

Therein among embodiment, described exhaust passage is extended and is evenly distributed in the attachment face plane from the elastic body center radiation.

Above-mentioned Support cushion by air chamber and exhaust passage are set at elastic body, can change by the air in the extruding air chamber bearing height of Support cushion.

Embodiment

Shown in Fig. 1 (a) and Fig. 1 (b), an embodiment Support cushion 10 comprises elastic body 100.The one side of elastic body 100 is attachment face 102 for support surface of contact 101, another side.Elastic body 100 offers from attachment face 102 intermediate portion openings and to the air chamber 103 that supports surface of contact 101 extensions.Also offer the exhaust passage 104 to the extension of elastic body 100 outer rims and perforation from air chamber 103 sidewalls on the elastic body 100.

Elastic body 100 adopts the elastic material with certain degree of hardness to make, thereby can support constant weight and have certain elasticity can be compressed and restore to the original state.In the present embodiment, elastic body 100 is preferably and adopts silica gel material to make.In the present embodiment, elastic body 100 integral body are discoid.

In the present embodiment, supporting surface of contact 101 is cambered surface.Elastic body 100 is to supporting the glomerate supporting portion of surface of contact 101 1 side-prominent shapes.In use, support surface of contact 101 and the Surface Contact that carries instrument and equipment.The cambered surface that supports surface of contact 101 can be sphere, ellipsoid and other similar shapes.

In the present embodiment, attachment face 102 is smooth plane, can be the instrument and equipment bottom surface stickup installation on plane with great majority.In other embodiments, attachment face 102 also can be other forms that match with the instrument and equipment bottom surface.

Air chamber 103 is opened in elastic body 100 and is opened on the intermediate portion of attachment face 102.The capacity of air chamber 103 is definite according to changing the factors such as height size and use occasion, and the capacity of air chamber 103 is larger, and adjustable altitude range is larger.

In the present embodiment, exhaust passage 104 is air vent, and this air vent is opened on attachment face 102 equally.In use, attachment face 102 and instrument and equipment bottom surface are close to, thereby air vent cooperates formation to be communicated with air chamber 103 and the outside through hole that also is used for exhaust with the instrument and equipment bottom surface.In other embodiments, exhaust passage 104 also can be exhaust hole, and namely exhaust passage 104 directly forms the through hole that is communicated with air chamber 103 and outside and is used for exhaust at elastic body 100 not at attachment face 102 openings.

In the present embodiment, the quantity of exhaust passage 104 is 4, extends and evenly distribution in attachment face 102 planes to external radiation from the center of elastic body 100.The quantity of exhaust passage 104 also can be other quantity more than 2, and a plurality of exhaust passages 104 can accelerate to discharge or suck air, reach the purpose of quick adjustment height.Evenly distributing then relatively is beneficial to installation, need not consider especially the direction of installing and is convenient to exhaust or air-breathing.

In addition, according to the extent of elasticity of elastic body 100 and the occasion of use, can rationally determine the aperture of exhaust passage 104, the complexity that enters or discharge to control gas.

Below in conjunction with Fig. 2 and Fig. 3 this Support cushion adjusting principle highly is described.

As shown in Figure 2, the Support cushion 10 of above-described embodiment is fitted with instrument and equipment 20 bottom surfaces, and this instrument and equipment 20 is placed on the plane of level.Under instrument and equipment 20 action of gravitations, elastic strain occurs in spherical supporting portion, and air chamber 103 is extruded and discharges air by exhaust passage 104.When this instrument and equipment 20 was placed on the plane of level, a plurality of Support cushions 10 were uniform stresseds, and the size that is stressed is identical, thereby deformation extent is consistent, can normally use.And after instrument and equipment 20 was raised, elastic body 100 recovered former state and air amount gradually in air chamber 103.

As shown in Figure 3, when this instrument and equipment 20 is placed on inclination or the irregular plane, can press extruding Support cushion 10 downwards by the end that instrument and equipment 20 positions are higher, make air chamber 103 discharge more gas, and in the situation that pushed air, elastic body 100 elasticity own are not enough to restore to the original state under the gravity of instrument and equipment 20, Support cushion 10 by instrument and equipment gravity extruding discharge air is then only kept bearing height before, thereby the height that the end that the height that the higher end in position supports is told somebody what one's real intentions are than the position supports is low, thereby keeps the use state of instrument and equipment 20 levels.Same, after instrument and equipment 20 was raised, elastic body 100 recovered former state and air amount gradually in air chamber 103.

The Support cushion 10 of above-described embodiment can be regulated instrument and equipment more easily to the laying state of level.

The above embodiment has only expressed several mode of execution of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
