Abstract

The utility model provides an air compressor, which comprises a pump box (20) in which an accommodating cavity is formed, a compression pump (10) arranged in the accommodating cavity of the pump box (20) and a shock absorption mechanism (40), wherein the shock absorption mechanism (40) comprises supporting pieces (41) which are supported by and connected with the compression pump (10) in a supporting manner, pull-up springs (42) which are connected to the corresponding supporting piece (41) by one end and to the pump box (20) by the upper end, and pull-down elastic parts (43) of which the two ends are connected with the supporting piece (41) and the bottom of the pump box (20) respectively. According to the air compressor, the pull-down elastic parts arranged on the shock absorption mechanism can prevent the compressor pump from moving upwards in case of small vibration; therefore, the compression pump can run steadily and is prevented from colliding with elements above the compression pump, generating noise or even being damaged.

Air compressor

Technical field

The utility model relates to the air compression field, in particular to a kind of air compressor.

Background technique

In the working procedure of medical air compressor, for vibrations and the noise that reduces compressor pump is generally its design one cover shock mitigation system, as: below compressor pump, add beam or up with spring suspension etc.When being employed in the top when use spring suspension, because of the vibrations in the transportation process, jolt, can make compressor pump upwards strike other device, cause damage.Usually above the transportation forward direction compressor pump and below fill in some sponges or rigid foam limits its motion, but the machine of handling like this is behind the destination, need open the thing that shell and pump box will fill in inside and take out, to install, test-run a machine makes troubles.

The model utility content

The utility model aims to provide a kind of air compressor of reliable damping, the noise and the safety problem that cause with the vibrations that solve compressor pump in the existing technology.

The utility model provides a kind of air compressor, comprises pump box, forms in the pump box and holds cavity; Compressor pump is arranged on holding in the cavity of pump box; Damper mechanism, the supporting parts that comprises the support and connection compressor pump and an end be connected with supporting parts on draw spring, on draw the upper end of spring to be connected on the pump box; Damper mechanism also comprises drop-down elastic member, and the one of which end connects supporting parts, and the other end is connected to the bottom of pump box.

Further, drop-down elastic member is a plurality of.

Further, drop-down elastic member is a spring.

Further, also comprise the base that is arranged on the pump box below, damper mechanism also comprises the fixed block that connects supporting parts and base.

Further, fixed block removably is connected with supporting parts.

Further, fixed block is the screw that passes base and be connected with supporting parts.

Further, be provided with beam between the screw head of screw and the base.

Further, fixed block is a plurality of.

According to the air compressor of the utility model, damper mechanism is provided with drop-down elastic member, when receiving small size vibrations, but the limit compression pump move upward, help the smooth running of compressor pump, avoid striking the device of its top, produce noise even damage.

Description of drawings

The accompanying drawing that constitutes the application's a part is used to provide the further understanding to the utility model, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:

Fig. 1 is the front sectional structure schematic representation according to the utility model air compressor;

Fig. 2 is the side sectional structure schematic representation according to the utility model air compressor;

Fig. 3 is the partial enlarged drawing of Fig. 2.

Embodiment

Below with reference to accompanying drawing and combine embodiment to specify the utility model.

As depicted in figs. 1 and 2, the air compressor according to the utility model comprises: pump box 20 forms in the pump box 20 and holds cavity; Compressor pump 10 is arranged on holding in the cavity of pump box 20; Damper mechanism 40, the supporting parts 41 that comprises support and connection compressor pump 10 and an end be connected with supporting parts 41 on draw spring 42, on draw the upper end of spring 42 to be connected on the pump box 20; Damper mechanism 40 also comprises drop-down elastic member 43, and the one of which end connects supporting parts 41, and the other end is connected to the bottom of pump box 20.Damper mechanism is provided with drop-down elastic member 43, when receiving small size vibrations, but the limit compression pump move upward, help the smooth running of compressor pump, avoid striking the device of its top, produce noise even damage.

Preferably, drop-down elastic member 43 is a plurality of, guarantees stress balance, and damping effect is more obvious.

Preferably, drop-down elastic member 43 is spring, and is simple and practical, and the little hook through both ends of the spring directly is hooked in the bottom of supporting parts 41 and pump box 20, and is easy for installation.

Air compressor also comprises the base 30 that is arranged on pump box 20 belows, in the long-distance transport process, can receive than big bang and jolts, so the damper mechanism 40 of this programme also comprises the fixed block 45 that connects supporting parts 41 and base 30.Fixed block 45 removably is connected with supporting parts 41.Before transportation, compressor pump is fixed on the base 30 of air compressor with fixed block 45, arrive the destination after, get final product in that fixed block 45 is taken off, fixed block 45 is also reusable.

Preferably, the screw of fixed block 45 for passing base 30 and being connected with supporting parts 41 has on the supporting parts 41 with the screw hole of screw fit or at supporting parts 41 bottom surface set screw nut spares 44.

In order to reduce the impact of screw head to base, as shown in Figure 3, be provided with beam 46 between the screw head of screw and the base 30, usually, shock absorber part 46 is a rubber pad.Preferably, fixed block 45 is a plurality of, and is fixing steadily reliable.

From above description, can find out that the utility model the above embodiments have realized following technique effect:

According to the air compressor of the utility model, damper mechanism is provided with drop-down elastic member, when receiving small size vibrations, but the limit compression pump move upward, help the smooth running of compressor pump, avoid striking the device of its top, produce noise even damage.When long-distance transport process etc. receives than big bang and jolts, adopt fixed block 45 that compressor pump is fixed on the base 30, prevent to collide the damage that causes.

The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
