[0030] like Figures 1 to 5 As shown, the utility model provides a technical solution: a highly sealed steam trap, comprising a steam trap body 1, steam trap pipes 2 are fixed on both sides of the steam trap body 1, a first connecting block 3 is fixed on the side of the steam trap pipe 2 away from the steam trap body 1, a second connecting block 4 is arranged on the side of the first connecting block 3 away from the steam trap pipe 2, a mounting plate 6 is fixed on the side of the first connecting block 3 close to the steam trap body 1, an adjusting box 5 is fixed on the side of the mounting plate 6 away from the second connecting block 4, an adjusting block 7 is slidably connected inside the adjusting box 5, a control box 10 is fixed on the top of the steam trap body 1, a fixing mechanism for limiting the adjusting block 7 is installed inside the control box 10, and the staff can fasten the first connecting block 3 and the second connecting block 4 through this arrangement.

[0031] The fixing mechanism includes a pulling block 8 fixed to the adjusting block 7 close to the second connecting block 4, a fitting block 9 is fixed to the side of the pulling block 8 away from the adjusting block 7, control grooves 11 are provided at both ends of the control box 10, a control block 12 is slidably connected inside the control groove 11, an insert block 13 is fixed to the bottom of the control block 12, and a slot 14 used in conjunction with the insert block 13 is provided on the top of the adjusting block 7. The staff pushes the control block 12 into the control groove 11, and the control block 12 drives the insert block 13 to release the limit between the insert block 13 and the slot 14. At the same time, the limit of the adjusting block 7 is also released, and the staff pulls the pulling block 8 outward so that the staff can connect the docking water pipe. After the staff connects the docking water pipe, the staff pushes the pulling block 8 to make the fitting block 9 abut against the second connecting block 4, so that the connection between the second connecting block 4 and the first connecting block 3 is more closed.

[0032] Slide grooves 15 are provided on both sides of the control groove 11, and sliders 16 are fixed on both sides of the control block 12. The surface of the slider 16 is slidably connected to the inside of the slide groove 15. When the staff moves the control block 12, the control block 12 drives the slider 16 to slide inside the slide groove 15. Through the above arrangement, the slider 16 can move with the movement of the control block 12, thereby realizing accurate positioning and rapid adjustment of the slider 16. The design of this mechanical structure not only simplifies the operating process and improves work efficiency, but also ensures the stability and reliability of the slider 16 during the movement.

[0033] A first spring 17 is fixed to the side of the control block 12 close to the control slot 11, and the side of the first spring 17 away from the control block 12 is fixed to the inside of the control slot 11. The staff pushes the control block 12 toward the inside of the control slot 11, and the control block 12 squeezes the first spring 17 for compression and force accumulation, while driving the plug block 13 to release the limit between it and the slot 14. The staff aligns the plug block 13 with the slot 14 and releases the control block 12. Under the action of the rebound force of the first spring 17, the control block 12 is quickly pushed, and the control block 12 drives the plug block 13 to be inserted into the slot 14 for fixation, thereby achieving the purpose of rapid limiting.

[0034] A second spring 18 is fixed to the side of the adjusting block 7 close to the inside of the adjusting box 5, and the side of the second spring 18 away from the adjusting block 7 is fixed to the inside of the adjusting box 5. When the staff pulls the pull block 8 outward, the pull block 8 drives the adjusting block 7 to move and drives the second spring 18 to stretch and accumulate force. When the staff releases the pull block 8, the second spring 18 rebounds quickly and drives the pull block 8 to retract toward the inside of the adjusting box 5, so that the staff can quickly fit the second connecting block 4.

[0035] Guide grooves 19 are provided at both ends of the adjusting box 5, and guide blocks 20 are fixed at both ends of the adjusting block 7. The surface of the guide block 20 is slidably connected to the inside of the guide groove 19. When the staff moves the adjusting block 7, the adjusting block 7 drives the guide block 20 to slide inside the guide groove 19. Through the above arrangement, the moving trajectory of the adjusting block 7 is fixed, and at the same time, the adjusting block 7 is prevented from falling off when extending outward.

[0036] The shape of the guide groove 19 is curved. Through the curved setting of the guide groove 19, when the adjustment block 7 moves to the left end of the guide groove 19, the adjustment block 7 drives the pulling block 8 to be lifted to the side close to the control box 10, so that the fitting block 9 and the second connecting block 4 are released. Through this setting, it is convenient for the staff to dock and install the first connecting block 3 and the second connecting block 4.

[0037] Working process:

[0038] The staff pushes the control block 12 into the control slot 11, and the control block 12 drives the plug block 13 to release the limit between it and the slot 14. At the same time, the limit of the adjusting block 7 is also released. The staff pulls the pull block 8 to the outside so that the staff can connect the water pipe. After the staff connects the water pipe, the staff pushes the pull block 8 to make the fitting block 9 fit the second connecting block 4 to abut against it, so that the second connecting block 4 and the first connecting block 3 are more tightly connected. When the staff moves the control block 12, the control block 12 drives the slider 16 to slide inside the slide slot 15. Through the above arrangement, the slider 16 can move with the movement of the control block 12, thereby realizing the precise positioning and rapid adjustment of the slider 16. The design of this mechanical structure not only simplifies the operation process and improves the work efficiency, but also ensures the stability and reliability of the slider 16 during the movement. The staff pushes the control block 12 into the control slot 11, and the control block 12 squeezes the first spring 17 to compress and store force, and at the same time drives the plug block 13 to release the limit between it and the slot 14. The staff aligns the plug block 13 with the slot 1 4 and release the control block 12. Under the action of the rebound force of the first spring 17, the control block 12 is quickly pushed, and the control block 12 drives the plug block 13 to be inserted into the slot 14 for fixing, so as to achieve the purpose of rapid limiting. When the staff pulls the pull block 8 outward, the pull block 8 drives the adjustment block 7 to move, and drives the second spring 18 to stretch and store force. When the staff releases the pull block 8, the second spring 18 rebounds quickly and drives the pull block 8 to retract toward the inside of the adjustment box 5, so that the staff can quickly fit the second connection block 4. When the staff makes the adjustment block 7 When moving, the adjusting block 7 drives the guide block 20 to slide inside the guide groove 19. Through the above arrangement, the moving trajectory of the adjusting block 7 is fixed, and at the same time, the adjusting block 7 is prevented from falling off when extending outward. Through the curved arrangement of the guide groove 19, when the adjusting block 7 moves to the left end of the guide groove 19, the adjusting block 7 drives the pulling block 8 to be lifted toward the side close to the control box 10, so that the fitting block 9 and the second connecting block 4 are released. Through this arrangement, the staff can easily dock and install the first connecting block 3 and the second connecting block 4.
