Description

Technical Field

[0001] The invention relates to the technical field of compressors, in particular to an air compressor. Background Art

[0002] An air compressor is a device used to compress gas. The structure of an air compressor is similar to that of a water pump. Most air compressors are reciprocating piston type, rotary blade or rotary screw, and centrifugal compressors. According to the working principle, they can be divided into three categories: volumetric type, dynamic type (speed type or turbine type), and thermal type compressors. According to the lubrication method, they can be divided into oil-free air compressors and oil-lubricated air compressors. According to performance, they can be divided into: low-noise, variable frequency, explosion-proof and other air compressors. According to the use, they can be divided into: refrigerator compressors, air conditioning compressors, refrigeration compressors, oil field compressors, natural gas filling stations, rock drills, pneumatic tools, vehicle braking, door and window opening and closing, textile machinery, tire inflation, plastic machinery compressors, mining compressors, marine compressors, medical compressors, sandblasting and painting.

[0003] The Chinese utility model with the publication number CN207297292U proposes an air compressor, which includes an air tank, at least two fixed rods are arranged below the air tank, and the bottom of the at least two fixed rods are connected to a fixed plate for sliding together, at least three casters are arranged at the bottom of the fixed plate, and a slide groove for sliding of the fixed rod is arranged on the fixed plate. After adopting the above technical solution, the air tank is moved within a large range by the casters. When the position of the air tank needs to be fine-tuned during operation, the fixed rod is moved so that the fixed rod slides in the slide groove, and the air tank is driven to move, so as to achieve fine-tuning of the position of the air tank, so that the air compressor can adjust the position within a small range. A slider matching the slide groove is arranged at the bottom of the fixed rod, and a through hole is arranged in the direction close to the side of the slide groove, and a plurality of slide holes are arranged on the fixed plate, and the slide hole and the through hole are matched with a fixing pin. After adopting the above technical solution, by arranging a slider corresponding to the slide groove, the fixed rod will not be lateral deflected when moving, so as to ensure that the fixed rod moves in the direction of the slide groove. By setting the sliding hole and the through hole, the through hole on the slider corresponds to one of the sliding holes on the fixed plate during the movement of the slider, and then the fixing pin is inserted into the sliding hole and passes through the through hole on the slider, thereby fixing the slider. The slider fixation fixes the position of the fixing rod, thereby ensuring that the position of the air compressor will not shift during operation.

[0004] However, the prior art still has shortcomings: when the compressor in the prior art is working, if it is rigidly fixed, the vibration cannot be effectively released, which can easily cause damage to the mechanical parts and generate noise. Secondly, the movement of the mechanical components and the compression of the gas will generate a lot of heat, so a corresponding radiator needs to be equipped, which will increase the cost of use.

[0010] As a further solution of the present invention: the air storage component includes an air storage airbag fixedly arranged inside the supporting frame, and one end of the air storage airbag is fixedly connected to one end of the push rod, and the movement of the two push rods away from each other can compress the corresponding air storage airbag so that the air inside the air storage airbag is transported to the inside of the air containing chamber.

When the air pressure reaches a certain requirement, the seal can be opened to allow air to blow to the air compressor body to achieve intermittent cooling. This setting uses the vibration of the air compressor body itself for intermittent cooling, and does not require an additional radiator, reducing the cost of use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figure 1-Figure 3 As shown, an air compressor comprises an air compressor body 1 and a mounting bracket assembly for carrying the air compressor body 1, wherein: Figure 1 It represents the use status of the air compressor body 1. During use, due to the special setting of the mounting bracket assembly in the present invention, the air compressor body 1 is in an active state as a whole during operation, and can be better buffered; and under this setting mode, the mounting bracket assembly can intermittently blow air to the air compressor body 1, thereby playing a certain heat dissipation role, without the need for an external radiator, easy to use, and reduced use cost.

[0027] Regarding the setting of the above-mentioned mounting bracket assembly, the mounting bracket assembly includes a supporting frame 2 and a storage plate 3 movably arranged on the top of the supporting frame 2, and the air compressor body 1 is installed on the storage plate 3. Specifically, a plurality of pads 18 are fixedly arranged on the top of the storage plate 3, and the air compressor body 1 is installed on the storage plate 3 through the plurality of pads 18.

[0028] like Figure 2As shown, two push rods 4 arranged opposite to each other are slidably arranged inside the bearing frame 2, and the storage plate 3 is movably connected to the two push rods 4 through a connecting piece. The storage plate 3 moves along the plumb direction to drive the two push rods 4 to move closer or farther, that is, during the use of the air compressor body 1, the storage plate 3 is driven to move in the plumb direction. Two air storage parts are arranged inside the bearing frame 2, and two air chambers 5 are provided on the storage plate 3. The two air storage parts are connected to the two air chambers 5 respectively, and the two push rods 4 act on one of the air storage parts respectively, so that the air storage parts supply air to the corresponding air chamber 5. The storage plate 3 is provided with an exhaust port 6 connected to the air chamber 5, and the exhaust port 6 is blocked by a sealing member. When the air pressure inside the air chamber 5 is large enough, the sealing member can open the exhaust port 6, so that the air inside the air chamber 5 is blown to the air compressor body 1, thereby achieving a cooling effect.

[0029] In order to realize the movable installation of the storage plate 3 on the supporting frame 2, a plurality of telescopic rods 7 can be fixedly arranged on the top of the supporting frame 2, the storage plate 3 is fixedly installed on the piston rods of the plurality of telescopic rods 7, and a plurality of first elastic members 8 fixedly connected to the storage plate 3 are arranged on the supporting frame 2. When the storage plate 3 moves up and down along the plumb direction, the first elastic member 8 will be compressed or stretched, and the telescopic rod 7 plays a limiting role. Preferably, the first elastic member 8 is set as a spring.

[0030] For example Figure 2 As shown, for the setting of the connecting member, the connecting member can be set to include a protrusion fixedly set at the bottom of the storage plate 3, and two connecting rods 9 are movably hinged on the protrusion, and the two connecting rods 9 are arranged in an eight-shaped shape, and the ends of the two connecting rods 9 that are far away from each other are movably connected to the two push rods 4 respectively; when the protrusion moves upward along the plumb direction, the two push rods 4 approach each other; when the protrusion moves downward along the plumb direction, the two push rods 4 move away from each other. Under normal circumstances, when the air compressor body 1 is working, it will drive the storage plate 3 to move up and down in the plumb direction, that is, it will drive the protrusion to move up and down in the plumb direction, and then the two push rods 4 can be moved closer or farther away from each other.

[0031] When the two push rods 4 move away from each other, the two push rods 4 will compress the corresponding air storage parts respectively, and then the air storage parts will transport the air inside them to the inside of the air chamber 5. During the resetting process of the push rods 4, the air storage parts can absorb and store the outside air; in this way, under the reciprocating motion of the push rods 4, the air storage parts can continuously transport air to the air chamber 5. When the air pressure reaches a certain requirement, the seal can be opened to allow the air to blow toward the air compressor body 1, achieving intermittent cooling. This setting uses the vibration of the air compressor body 1 to perform intermittent cooling, and does not require an additional radiator, which reduces the cost of use.

[0032] like Figure 2-Figure 3 As shown, for the arrangement of the above-mentioned air storage component, the air storage component includes an air storage bag 10 fixedly arranged inside the bearing frame 2, and one end of the air storage bag 10 is fixedly connected to one end of the push rod 4, and the movement of the two push rods 4 away from each other can compress the corresponding air storage bag 10, so that the air inside the air storage bag 10 is transported to the inside of the air storage chamber 5. Further, the air storage bag 10 is connected with an air inlet pipe 11, and the air inlet pipe 11 is provided with a first one-way valve 12, and the air storage bag 10 is connected with an air outlet pipe 13, and the air outlet pipe 13 is connected with the air storage chamber 5, and the air outlet pipe 13 is provided with a second one-way valve 14, so that the air outlet pipe 13 can supply air to the air storage chamber 5 in one direction. When the two push rods 4 move away from each other to compress the air storage airbag 10, since the first one-way valve 12 is arranged on the air inlet pipe 11, the first one-way valve 12 can prevent the air inside the air storage airbag 10 from leaking out through the air inlet pipe 11, and the air inside the air storage airbag 10 can only be transported to the air containing chamber 5 through the air outlet pipe 13; when the two push rods 4 approach each other, the corresponding air storage airbag 10 can be stretched, and under the action of the air inlet pipe 11 and the first one-way valve 12, the outside air will be transported to the air storage airbag 10 through the air inlet pipe 11, and under the action of the second one-way valve 14, the air inside the air containing chamber 5 will not be transported back to the air storage airbag 10.

[0033] like Figure 3 As shown, the sealing member includes a cover plate 15 that is hingedly arranged at the periphery of the exhaust port 6, and a second elastic member 16 that is fixedly connected to the cover plate 15 is arranged inside the air chamber 5. The second elastic member 16 is used to make the cover plate 15 have a tendency to rotate close to the exhaust port 6 until the exhaust port 6 is covered. A sealing gasket 17 is fixedly arranged on the side facing the exhaust port 6. When the cover plate 15 covers the exhaust port 6, the sealing gasket 17 covers and presses against the exhaust port 6.

[0034] Specifically, when the air pressure inside the air chamber 5 gradually increases to a certain extent, that is, when the air pressure is greater than the elastic force applied by the second elastic member 16 to the cover plate 15, the cover plate 15 can open the exhaust port 6, and then the air inside the air chamber 5 will be blown to the air compressor body 1 through the exhaust port 6 to achieve a cooling process. When part of the air inside the air chamber 5 is discharged, that is, when the elastic force applied by the second elastic member 16 to the cover plate 15 is greater than the air pressure, the cover plate 15 will cover the exhaust port 6 again to seal it. Preferably, the second elastic member 16 is set as a spring.

[0035] In order to ensure the stability of the movement of the two push rods 4 inside the supporting frame 2, a slider 19 can be fixedly provided at the bottom of the push rod 4, and a limit rod 20 can be fixedly provided at the bottom of the supporting frame 2, and the slider 19 is slidably installed on the limit rod 20.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
