Description

Technical Field

[0001] This utility model relates to the field of gasoline generator technology, and in particular to a maintenance port for a gasoline generator. Background Technology

[0002] A gasoline generator typically consists of a stator, rotor, end covers, and bearings. An engine is a machine that converts chemical energy into mechanical energy. This conversion process is essentially a work cycle; simply put, it involves burning fuel in the cylinders to generate kinetic energy, which drives the piston in the cylinders to reciprocate. This, in turn, drives the connecting rod and the crankshaft connected to the piston to reciprocate around the crankshaft, thus outputting power. The stator consists of a stator core, winding coils, a frame, and other structural components that hold these parts in place. The rotor consists of a rotor core (or magnetic poles, yoke), winding coils, retaining rings, a center ring, slip rings, a fan, and a shaft. Bearings and end covers connect and assemble the generator's stator and rotor, allowing the rotor to rotate within the stator and cut magnetic lines of force, generating an induced electromotive force (EMF). This EMF is then led out through terminals and connected to a circuit, producing an electric current.

[0003] The spark plugs in a gasoline generator need to be replaced after long-term use. Therefore, an inspection port is provided on the casing of the gasoline generator to replace the spark plugs. However, the inspection cover of the conventional gasoline generator inspection port is difficult to pry open after installation, making it inconvenient to use. Utility Model Content

[0004] The purpose of this utility model is to provide a maintenance port for a gasoline generator, which solves the problem that the maintenance cover of a conventional gasoline generator maintenance port is difficult to snap on after installation, making it inconvenient to use.

[0005] To achieve the above objectives, this utility model provides a maintenance port for a gasoline generator, including a generator housing with a maintenance port on the housing. The generator housing also has a slot on the side near the maintenance port. The device further includes a sealing device comprising a sealing cover, a latch, a latch frame, a guide frame, a guide bar, a tensioning assembly, and a pushing assembly. The latch is fixedly installed inside the maintenance port. The sealing cover engages with the maintenance port. A latching block is provided on the sealing cover, engaging with the slot. The guide frame and the guide bar are both fixedly installed on the sealing cover. The latch is slidably installed on the guide frame and the guide bar via the tensioning assembly and engages with the latch. A pushing frame is also provided on the latch frame, and the pushing assembly is installed on the sealing cover.

[0006] The tensioning assembly includes a connecting block and a tension spring, wherein the connecting block is fixedly installed on the buckle; and the tension spring is fixedly installed on the connecting block.

[0007] The push assembly includes a top cone, a connecting rod, and a rotating component. The connecting rod is threadedly engaged with the closed cover plate. The top cone is fixedly mounted on the connecting rod. The rotating component is disposed on the connecting rod.

[0008] The rotating component includes a rotating disk and an anti-slip strip. The rotating disk is fixedly installed on the connecting rod and located at the end of the connecting rod away from the top cone. The anti-slip strip is fixedly installed on the rotating disk.

[0009] The sealed cover plate is also provided with a sound insulation layer, which is fixedly installed on the sealed cover plate.

[0010] This utility model discloses a maintenance port for a gasoline generator. When the closed cover needs to be disassembled, rotating the rotating disk causes the connecting rod to rotate. Since the connecting rod is threadedly connected to the closed cover, it moves downwards during rotation. The connecting rod causes the top cone to move downwards, and the pushers on both sides are spread apart. This causes the pushers to move the buckles on both sides away from each other along the guide frame and guide bar. When the lower end of the buckle disengages from the buckle rod, the closed cover is lifted, causing the locking block to disengage from the locking groove. At this point, the closed cover can be disassembled. The push assembly then pushes the buckles on both sides in the opposite direction, causing them to disengage from the buckle rod, thus making the disassembly of the closed cover more convenient.

Detailed Implementation

[0016] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0017] The embodiment of this application is as follows: Please see Figure 1-3 , Figure 1 This is a schematic diagram of the overall structure of the inspection port of a gasoline generator according to this utility model. Figure 2 This is a schematic diagram of the inspection port structure of this utility model. Figure 3 This is a schematic diagram of the sealing device of this utility model.

[0018] This utility model provides a maintenance port for a gasoline generator, including a generator housing 101 and a sealing device. The sealing device includes a sealing cover 103, a latch 104, a latch frame 105, a guide frame 106, a guide bar 115, a tensioning assembly, and a pushing assembly. The tensioning assembly includes a connecting block 107 and a tension spring 108. The pushing assembly includes a top cone 109, a connecting rod 110, and a rotating component. The rotating component includes a rotating disk 111 and an anti-slip strip 112. The sealing cover 103 is also provided with a sound insulation layer 113. The above solution solves the problem that the maintenance cover of a conventional gasoline generator maintenance port is difficult to fasten after installation, making it inconvenient to use.

[0019] In this embodiment, the push assembly pushes the buckle 105 on both sides in the opposite direction, causing the buckle 105 to disengage from the buckle rod 104, thereby allowing the closed cover 103 to be removed, which makes the removal of the closed cover 103 more convenient.

[0020] The buckle 104 is fixedly installed inside the inspection port 102. The sealing cover 103 is fastened to the inspection port 102. The sealing cover 103 is provided with a locking block 116, which engages with the locking groove 114. The guide frame 106 and the guide bar 115 are both fixedly installed on the sealing cover 103. The buckle frame 105 is slidably installed on the guide frame 106 and the guide bar 115 through the tensioning assembly and is fastened to the buckle 104. The buckle frame 105 is also provided with a pusher 117, and the pusher assembly is installed on the sealing cover 103. The buckle 104 is a cylindrical structure, and the buckle frame 105 is a U-shaped structure. The lower end of the buckle 105 is shorter than the upper end of the buckle 105. The guide bar 115 is a long rectangular structure, while the guide frame 106 is an L-shaped structure. Through the cooperation of the guide bar 115 and the guide frame 106, the movement of the buckle 105 can be guided. The tensioning component can pull the buckles 105 on both sides towards each other. The pushing component pushes the pushers 117 and buckles 105 on both sides in opposite directions, so that the buckles 105 disengage from the buckle rod 104. By lifting the closing cover 103, the locking block 116 disengages from the locking groove 114, thereby making the disassembly of the closing cover 103 more convenient.

[0021] Secondly, the connecting block 107 is fixedly installed on the buckle 105; the tension spring 108 is fixedly installed on the connecting block 107, the connecting block 107 is fused to the buckle 105, and the tension spring 108 is disposed between the connecting blocks 107 on both sides. Through the arrangement of the tension spring 108, the elastic force of the tension spring 108 drives the buckles 105 on both sides to maintain the initial state of being fastened with the buckle rod 104 through the connecting block 107.

[0022] Furthermore, the connecting rod 110 is threadedly engaged with the closed cover plate 103; the top cone 109 is fixedly installed on the connecting rod 110; the rotating component is disposed on the connecting rod 110, the connecting rod 110 is threaded, and the top cone 109 has a conical structure with a thinner lower end. The rotating component drives the connecting rod 110 to rotate, so that the connecting rod 110 drives the top cone 109 to move through the threaded transmission, thereby enabling the top cone 109 to push the pushers 117 on both sides in the opposite direction.

[0023] Furthermore, the rotating disk 111 is fixedly installed on the connecting rod 110 and located at the end of the connecting rod 110 away from the top cone 109; the anti-slip strip 112 is fixedly installed on the rotating disk 111. The rotating disk 111 has a disc structure, and the anti-slip strip 112 is arranged in a ring around the outer periphery of the rotating disk 111. By rotating the rotating disk 111, it is easy to drive the connecting rod 110 to rotate.

[0024] Finally, the sound insulation layer 113 is fixedly installed on the closed cover plate 103. The sound insulation layer 113 is made of sound insulation cotton. By setting the sound insulation layer 113, the leakage of internal noise of the generator housing 101 can be reduced.

[0025] In this embodiment, when it is necessary to disassemble the sealing cover 103, the rotating disk 111 is rotated, causing the rotating disk 111 to drive the connecting rod 110 to rotate. Since the connecting rod 110 is threadedly connected to the sealing cover 103, the connecting rod 110 moves downward during rotation. The connecting rod 110 drives the top cone 109 to move downward, and pushes the pushers 117 on both sides to the sides, so that the pushers drive the buckles 105 on both sides along the guide. The bracket 106 and the guide bar 115 are separated from each other. When the lower end of the buckle 105 is disengaged from the buckle bar 104, the closing cover 103 is lifted up, so that the locking block 116 is disengaged from the locking groove 114. At this time, the closing cover 103 can be removed. Then, the buckle 105 on both sides is pushed in the opposite direction by the pushing component, so that the buckle 105 is disengaged from the buckle bar 104, and the closing cover 103 is removed, thus making the removal of the closing cover 103 more convenient.

[0026] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
