DETAILED DESCRIPTION
[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] Reference Figure 1-Figure 4 The utility model provides an embodiment: a steam heating temperature reduction and pressure reduction control device, comprising a shell 1 and a protective cover 13, a control device body 2 is slidably connected inside the shell 1, a fixing plate 3 is fixedly connected between the control device body 2 and the shell 1, an adjusting frame 11 is hinged on one side of the fixing plate 3, a fixing block 4 is abutted on one side of the control device body 2, a fixing block 2 7 is fixedly connected to the bottom of the fixing block 4, a connecting shaft 5 is fixedly connected to the bottom of the fixing block 2 7, one end of the connecting shaft 5 slides on one side of the shell 1, a spring 1 6 is sleeved on the outer wall of the connecting shaft 5, connecting rods 8 are hinged on both sides of the fixing block 2 7, one end of the connecting rod 8 passes through the adjusting frame 11 and is fixedly connected to a limiting block 10, the limiting block 10 slides in the adjusting frame 11, and a spring 2 9 is sleeved on the outer wall of the connecting rod 8.
[0029] Among them, a fixing column 2 16 is fixedly connected to one side of the shell 1, and a sliding groove 17 is provided on the outer wall of the fixing column 2 16. A fixing column 15 is slidably connected to the middle part of the fixing column 2 16. A limiting column 19 is fixedly connected to the outer wall of the fixing column 15, and the limiting column 19 is slidably connected to the sliding groove 17. A spring 3 18 is fixedly connected to the bottom of the fixing column 15, and one end of the spring 3 18 is fixedly connected to the shell 1, and one end of the fixing column 15 is fixedly connected to the protective cover 13. A handle 14 is fixedly connected to one side of the protective cover 13. This design allows the protective cover 13 to be quickly removed or installed from the control device. A heat dissipation hole 12 is provided on the control device body 2, which helps to dissipate heat when the device is running. A side door 20 is rotatably connected to one side of the shell 1. A group of fixing blocks 4 are respectively arranged on both sides of the control device body 2. The sliding groove 17 is L-shaped. The L-shaped design of the sliding groove 17 makes the limiting column 19 unable to continue sliding after sliding to a certain position due to the restriction of the L-shaped groove, thereby achieving the fixation of the protective cover 13.
[0030] Working principle: The staff moves the steam heating temperature reduction and pressure reduction control device to a suitable position. When the external force hits the shell 1, the connecting shaft 5 slides on one side of the shell 1, and the spring 16 squeezes the outer wall of the connecting shaft 5. The connecting shaft 5 drives the fixed block 27 to move, and the fixed block 27 drives the fixed block 14 to abut against the outer wall of the control device body 2. The connecting rods 8 on both sides of the fixed block 27 slide in the adjustment frame 11, and the limit block 10 at one end of the connecting rod 8 slides in the adjustment frame 11. The spring 29 squeezes the outer wall of the connecting rod 8, and the adjustment frame 11 One end is hinged on one side of the fixing plate 3 to achieve buffering of the control device body 2. The staff presses the handle 14, and the handle 14 drives the fixing column 15 to slide in the fixing column 2 16. The spring 3 18 at the bottom of the fixing column 15 is squeezed between the shell 1 and the fixing column 15, and the limiting column 19 on the outer wall of the fixing column 15 slides in the slide groove 17. Since the slide groove 17 is L-shaped, when the limiting column 19 slides to the corner of the L-shaped slide groove 17, the protection cover 13 is fixed and limited, so that the protection cover 13 protects the shell 1.
[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
