Description
Technical Field
[0001] This utility model belongs to the technical field of municipal plumbing repair tools, and in particular relates to a radiator venting and anti-splash device. Background Technology
[0002] In the initial stages of heating system activation in northern cities during winter, maintenance workers need to adjust the pressure relief and balance of the heating systems based on user feedback. In the past, when adjusting the pressure relief of radiators, maintenance workers would first align a screwdriver with the pressure relief screw on the upper side of the radiator, and then cover the pressure relief port of the radiator with a towel or plastic bag. They would then adjust the pressure relief screw until water was drained. This process was not intuitive. The towel was folded and covered the pressure relief port, and it could only be observed when a large amount of water was drained. The towel was often wet and inconvenient to carry. Moreover, sometimes the towel could not completely prevent pressurized water from spraying onto the walls or floor, causing dirty, hot water to splash onto people or walls, resulting in burns or wall stains. Utility Model Content
[0003] In view of this, the purpose of this utility model is to provide a radiator venting and anti-splash device to solve the technical problems in the prior art where covering the radiator vent with a towel makes it inconvenient to observe or cannot completely prevent pressurized water from spraying onto the wall or floor.

The handle 4 has an elongated hole extending in the left-right direction, and a slider 13 that is fitted to the elongated hole is fixed on the rack 19. By pushing the slider 13 in the left and right directions, the slider 13 drives the rack 19 to move in the left and right directions, thereby driving the gear 18 to rotate. The rotation of the gear 18 drives the screwdriver shank 7, which meshes with it, to move in the left and right directions, thereby realizing the left and right movement of the screwdriver shank 7 relative to the protective cover 3, so that the flat end of the screwdriver shank 7 can contact and tighten with the screw head at the pressure relief port 2 of the radiator 1.
[0043] In order to increase the friction when gripping the handle 4, in this embodiment, a rubber layer 11 is fixedly provided on the outer side of the handle 4, and an avoidance hole 12 is provided on the rubber layer 11 corresponding to the elongated hole.
[0044] To ensure the stability of the screwdriver shank 7 when it moves left and right within the protective cover 3, in this embodiment, a guide 15 is fixed to the side of the annular stop 14 away from the handle 4. The guide 15 includes a large-diameter section fixed to the annular stop 14 and a small-diameter section integrally formed with the large-diameter section. The guide 15 has a guide hole corresponding to the center hole of the annular stop 14. The guide hole passes through the large-diameter section and the small-diameter section of the guide 15 in the left and right direction, and the screwdriver shank 7 is guided and adapted to the guide hole.
[0045] In this embodiment, the screwdriver shaft 7 is prevented from rotating circumferentially relative to the central axis of the handle 4. Specifically, a square prism 20 is fixed to the end of the guide cavity 17 away from the radiator 1, and a square hole 21 is provided at the end of the screwdriver shaft 7 facing the square prism 20.
