DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example

[0021] See also Figure 1-4 , a fueling gun that is easy to replace the nozzle, including a fueling gun body 1, a fuel gun switch 2 is provided on the right side of the fueling gun body 1, an oil inlet pipe 3 is passed through and fixedly connected to the right side of the fueling gun body 1, an oil outlet pipe 4 is passed through and fixedly connected to the left side of the fueling gun body 1, and a nozzle replacement mechanism 5 is provided at the end of the oil outlet pipe 4 away from the fueling gun body 1, and a dustproof mechanism 6 is provided on the surface of the oil outlet pipe 4. The nozzle replacement mechanism 5 includes a nozzle 51 and a slot 57. An insertion port 52 and an insert block 53 are fixedly connected to the right side of the nozzle 51. The size of the slot 57 opening is the same as that of the insert block 53. The outer diameter of the insertion port 52 is the same as the inner diameter of the oil outlet pipe 4. The insert block 53 can be inserted into the slot 57, and the insertion port 52 can be inserted into the oil outlet Inside the tube 4, a groove 54 is provided on the top of the plug block 53, and an arc block 56 is slidably connected to the inside of the groove 54 through a telescopic spring 55. A slot 57 is provided at the end of the oil outlet pipe 4 away from the fuel gun body 1. The depth of the slot 57 is equal to the length of the plug block 53, and the depth of the groove 54 is greater than the length of the arc block 56. When the plug block 53 is fully inserted into the slot 57, the nozzle 51 fits tightly against the oil outlet pipe 4, and the arc block 56 can be completely retracted into the groove 54. A card slot 58 is provided on the top of the inner part of the slot 57. The size of the opening of the groove 54 is equal to the size of the opening of the card slot 58. The arc surface of the arc block 56 is to the right, and the arc block 56 can be stuck in the card slot 58. When the arc surface of the arc block 56 is squeezed, it will move into the groove 54.

[0022] When in use, select different nozzles 51 according to work requirements. When installing, align the side insertion port 52 of the nozzle 51 with the oil outlet pipe 4 and insert the plug block 53 with the slot 57. When the plug block 53 is fully inserted into the slot 57, the nozzle 51 fits tightly with the oil outlet pipe 4. During the insertion of the plug block 53 into the slot 57, the arc block 56 is squeezed at the beginning and moves into the groove 54, and is completely retracted into the groove 54. The telescopic spring 55 is tightened. When the groove 54 fits with the slot 58, the telescopic spring 55 rebounds and drives the arc block 56 to be clamped into the slot 58. At this time, the nozzle 51 and the oil outlet pipe 4 can no longer be separated, thereby completing the installation. When disassembly is required, use a tool to press the arc block 56 to make it leave the slot 58 and retract it into the groove 54 to separate the nozzle 51 and the oil outlet pipe 4. The installation and disassembly are simple, and the nozzle 51 is easy to replace. Example

[0023] See also Figure 1-6 On the basis of embodiment 1, the dustproof mechanism 6 includes a fixed block 61, which is fixedly connected to the surface of the oil outlet pipe 4. A slide groove 62 is provided at the bottom of the fixed block 61. The interior of the slide groove 62 is slidably connected to a stop block 64 through a compression spring 63. A pressure rod 65 is passed through the top of the fixed block 61 and slidably connected. The bottom of the pressure rod 65 is fixedly connected to the stop block 64. The size of the opening of the slide groove 62 is equal to the size of the opening of the card slot 58. The elastic potential energy of the compression spring 63 is less than the elastic potential energy of the telescopic spring 55. The stop block 64 can enter the card slot 58. When the arc block 56 is stuck in the card slot 58, it will squeeze the stop block 64 to retract it into the slide groove 62.

[0024] During use, based on Example 1, when the oil outlet pipe 4 is used alone, the block 64 will enter the slot 58 under the action of the compression spring 63 to close the slot 58, preventing dust from entering the slot 57 through the slot 58 and affecting the subsequent installation of the nozzle 51. When the nozzle 51 is installed, the arc block 56 will be stuck in the slot 58 to squeeze the block 64 and retract it into the slide groove 62, which will not affect the installation of the nozzle 51. When the nozzle 51 is removed, the pressure rod 65 can be pressed down to drive the block 64 to squeeze the arc block 56 so that the arc block 56 leaves the slot 58 and retracts into the groove 54.

[0025] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
