Description

Technical Field

[0001] The utility model belongs to the field of air compressors, and relates to an air compressor, in particular to a new type of air compressor. Background Art

[0002] An air compressor is a commonly used air compression device for compressing air and supplying air to various pneumatic tools. An air compressor generally includes a machine head and a gas storage tank, and a pressure switch, a safety valve, a pressure gauge, and a gas supply joint need to be installed on the gas storage tank.

[0003] In order to facilitate processing, the existing gas storage tank usually only has one air outlet pipe. The pressure switch, the safety valve, the pressure gauge, and the gas supply joint all need to be communicated with the inner cavity of the gas storage tank through the air outlet pipe. This makes it necessary to install a pipeline or joint with a relatively complex structure at the end of the air outlet pipe for installing these components. The joint usually adopts a threaded interface and a flange interface, and the connection method is single. When the air compressor works, it vibrates, thereby reducing the tightness of the connection between the air outlet pipe joint and the pipeline, resulting in situations such as pressure relief, which seriously affects the service life of the air compressor. Summary of the Invention

[0004] The purpose of the utility model is to provide a new type of air compressor to solve the above problems in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved by the following technical solutions: A new type of air compressor includes an air compressor main body with an air outlet end, and connecting pipes are provided at the air outlet ends of the air compressor main body. It is characterized in that a quick connection device for quick connection is arranged between the air outlet end of the air compressor main body and the connecting pipe;

[0006] The quick connection device includes two quick connection parts for quick connection, two sealing flaps for improving the sealing strength, and a locking component for locking and fixing;

[0007] The two quick connection parts are hinged to each other through a pin shaft, and the quick connection parts can rotate circumferentially along the center line of the pin shaft;

[0008] The two sealing flaps are inlaid and installed on the inner side walls of the quick connection parts;

[0009] The two quick connection parts and the sealing flaps are both arranged in a semi-circular structure and are arranged in a relative structure. A plurality of sealing strips for squeezing and sealing the outside of the connecting pipe and the outer wall of the air outlet end are arranged on the inner side walls of the sealing flaps;

[0010] The locking component is composed of two connection seats respectively located on the corresponding quick connection parts, a movable union bolt, and a nut part cooperating with the union bolt.

[0011] In the above-mentioned new type of air compressor, a ring groove for facilitating connection and limit is provided in the middle of the inner side of the sealing flap. Through continuous adjustment of the locking assembly, a number of the sealing strips continuously extrude and fit against the connecting pipe and the outside of the air outlet end, forming multiple layers of seals.

[0012] In the above-mentioned new type of air compressor, a number of the sealing strips are arranged at intervals in sequence along the inner side of the sealing flap. Both the sealing flap and the sealing strips are integrally formed from a highly sealing rubber material.

[0013] In the above-mentioned new type of air compressor, between the mating connection parts of the two sealing flaps, there are sealing protrusions and sealing grooves for enhancing the sealing strength. The cross-sections of both the sealing protrusions and the sealing grooves are arc-shaped structures.

[0014] In the above-mentioned new type of air compressor, the connection seats are all arranged in a U-shaped structure. The loose joint bolts are movably connected to the connection seats of the corresponding quick-connecting parts through connection pins and cooperate with nuts to achieve locking.

[0015] Compared with the prior art, the new type of air compressor has a simple structure. With the cooperation of the quick-connecting device structure, it can achieve quick connection. At the same time, it can effectively make the inner side of the sealing flap and a number of the sealing strips tightly squeeze and fit against the outside of the connecting pipe and the outside of the air outlet end, and form multiple layers of seals, greatly improving the tightness of the connection between the air outlet end and the connecting pipe and preventing problems such as gas leakage.

[0019] The following are specific embodiments of the present invention in combination with the drawings, further describing the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0020] Such as Figure 1 、 Figure 2As shown in the figure, the present new air compressor includes an air compressor main body 1 with an air outlet end. Connecting pipes 2 are provided at the air outlet ends of the air compressor main body 1. A quick-connecting device for quick connection is arranged between the air outlet end of the air compressor main body 1 and the connecting pipe 2. The quick-connecting device includes two quick-connecting parts 3 for quick connection, two sealing flaps 4 for improving the sealing strength, and a locking component for locking and fixing. The two quick-connecting parts 3 are hinged to each other through a pin shaft 5. The quick-connecting part 3 can rotate circumferentially along the center line of the pin shaft 5. The two sealing flaps 4 are embedded and installed on the inner side walls of the quick-connecting parts 3. The two quick-connecting parts 3 and the sealing flaps 4 are both arranged in a semi-circular structure and are in a relative structure. A number of sealing strips 6 for extrusion sealing with the outer part of the connecting pipe 2 and the outer wall of the air outlet end are arranged on the inner side walls of the sealing flaps 4. The locking component is composed of two connecting seats 7 respectively located on the corresponding quick-connecting parts 3, a movable union bolt 8, and a nut part 9 cooperating with the union bolt 8.

[0021] The above structure is simple. With the cooperation of the quick-connecting device structure, while achieving quick connection, at the same time, it can effectively make the inner side of the sealing flap 4 and a number of sealing strips 6 closely squeeze and fit on the outer part of the connecting pipe 2 and the outer part of the air outlet end, and form multiple layers of seals, greatly improving the tightness of the connection between the air outlet end and the connecting pipe 2 and preventing problems such as gas leakage.

[0022] Further elaborating, in order to facilitate the realization of high sealing strength at the connection, a ring groove 10 for facilitating connection and limitation is opened in the middle of the inner side of the sealing flap 4. Through continuous adjustment of the locking component, a number of sealing strips 6 continuously squeeze and fit on the outer part of the connecting pipe 2 and the air outlet end to form multiple layers of seals. The aforenamed a number of sealing strips 6 are arranged at intervals in sequence along the inner side of the sealing flap 4. The sealing flap 4 and the sealing strips 6 are integrally formed by a high-sealing rubber material. Between the cooperating connection parts of the two sealing flaps 4, there are sealing protrusions and sealing grooves for improving the sealing strength. The cross-sections of the sealing protrusions and the sealing grooves are both arc structures. The design of this arc structure enables it to have a cooperating guiding effect. At the same time, it is convenient for the sealing protrusions to be extruded and deformed to fill into the sealing grooves to form a high-sealing structure.

[0023] Further elaborating, in order to facilitate locking and adjustment, the connecting seats 7 are both arranged in a U-shaped structure. The union bolt 8 is movably connected to the connecting seat 7 of the corresponding quick-connecting part 3 through a connecting pin 11 and cooperates with the nut to achieve locking.

[0024] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the technical field to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar ways to substitute, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0025] Although terms such as air compressor main body 1, connecting pipe 2, quick connector 3, sealing flap 4, pin shaft 5, sealing strip 6, connecting seat 7, union bolt 8, nut part 9, annular groove 10, connecting pin 11, etc. are used more frequently in this text, the possibility of using other terms is not excluded.
