Detailed Implementation
[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.
[0027] like Figure 1 and Figure 2 As shown, a mine-use safety-enhanced electric heater includes: a safety-enhanced heater body 20. The safety-enhanced heater body 20 is a conventional safety-enhanced electric heater, which is existing technology and will not be described in detail here.
[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a support structure is installed at the bottom of the increased safety heater body 20 to support the increased safety heater body 20. The support structure includes: a fixed joint 30, a rotating column 31, a side plate 32, a movable column 34, and a support plate 35. The fixed joints 30 are symmetrically fixedly connected to the bottom of the increased safety heater body 20. The rotating column 31 is rotatably connected to the wall surface of each fixed joint 30. The side plate 32 is symmetrically fixedly connected to both sides of each rotating column 31. The movable column 34 is rotatably connected between each set of symmetrical side plates 32. The support plate 35 is fixedly connected to the top wall surface of each movable column 34. The side plate 32 can be flipped at the bottom of the increased safety heater body 20.
[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the fixed joint 30 is a rod with a semi-capsule-shaped cross-section. A circular groove adapted to the rotation of the rotating column 31 is opened through the side wall of the fixed joint 30. The side plate 32 is a capsule-shaped plate. A circular hole adapted to the insertion of the movable column 34 is opened on the front side wall of the side plate 32. The support plate 35 is a plate with an L-shaped cross-section. The support structure also includes a locking groove 33, a fixed block 40, a sliding groove 41, a handle 42, a spring plate 43, and a locking rod 44. The locking groove 33 is opened on the side wall of each side plate 32. The fixed blocks 40 are symmetrically fixed to both sides of the increased safety heater body 20. The sliding groove 41 is opened on the side wall of the symmetrical fixed blocks 40 facing each other. The handle 42 is slidably connected to the wall of the fixed block 40. The spring plate 43 is located at the front and rear of the handle 42. Each side of the wall is fixedly connected. The locking rod 44 is symmetrically fixedly connected to the bottom end of the fixed block 40. The locking groove 33 is located at the connection between the side plate 32 and the rotating column 31. The locking groove 33 is an L-shaped groove. The fixed block 40 is a rectangular block. The sliding groove 41 is a cross-shaped groove. The handle 42 is an U-shaped rod with the opening facing down. The bottom two ends of the handle 42 can slide along the sliding groove 41 of the symmetrical fixed block 40. Each spring plate 43 is located in the sliding groove 41. The spring plate 43 is a rectangular plate. The top of each spring plate 43 is fixedly connected to a spring. The top of the spring can abut against the upper part of the sliding groove 41. The locking rod 44 is a U-shaped rod with the opening facing down. The bottom end of the locking rod 44 on each side can be inserted into the locking groove 33 of the wall of the symmetrical side plate 32 on each side.
[0030] In practical use, first pull the handle 42 upwards. When the handle 42 is pulled, it will cause the spring plate 43 to slide along the slide groove 41. When the spring plate 43 slides, the spring at the top will be compressed. The locking rod 44 will also move synchronously with the movement of the handle 42. At this time, the locking rod 44 will separate from the locking groove 33 when it moves upwards. When the locking rod 44 separates from the locking groove 33, the angle between the rotating column 31 and the side plate 32 will be unlocked. The side plate 32 will rotate downwards with the rotating column 31 as the center due to gravity. The support plate 35 will swing synchronously with the swing of the side plate 32. The support plate 35 will rotate around the center of the movable column 34. The symmetrical side plate 32 will flip synchronously. At this time, the symmetrical side plate 32 will change from the original horizontal state to the vertical state. When the side plate 32 is in a vertical position, release the handle 42. At this time, the spring at the top of the spring plate 43 will push the spring plate 43 downward. The spring plate 43 will drive the locking rod 44 to move downward and insert into the opening of the locking groove 33 facing upward. The locking groove 33 will change the opening orientation as the side plate 32 rotates. Then, adjust the symmetrical support plate 35 to a flat position. At this time, the increased safety heater body 20 can be supported in the mine for heating. When storing, continue to lift the handle 42, then unlock the position of the side plate 32, and then adjust the symmetrical support plate 35 with the rotating column 31 as the center to cover the front and rear walls of the increased safety heater body 20. Then, release the handle 42 and use the locking rod 44 to insert into the locking groove 33 to fix the side plate 32.
[0031] In summary, by setting up a support structure, the increased safety heater body 20 can be protected by covering the front and rear walls of the increased safety heater body 20 with the support plate 35 when it is idle, and can be quickly unfolded to support the increased safety heater body 20 when in use.
[0032] like Figure 5 As shown, the bottom end of the front support plate 35 is provided with a connecting groove 37, and the bottom of the rear support plate 35 is fixedly connected with a connecting rod 36. The connecting groove 37 is a rectangular groove, and the connecting rod 36 is a rectangular rod. The connecting rod 36 can be inserted into the connecting groove 37, and the connecting groove 37 can be adapted to the size of the connecting rod 36.
[0033] In practical use, when the symmetrical support plate 35 is in a flat support state, the connecting rod 36 is connected to the connecting groove 37, and the symmetrical support plate 35 will be flush and fixed.
[0034] In summary, by setting the connecting rod 36 and the connecting groove 37, the position of the symmetrical support plate 35 can be restricted when the symmetrical support plate 35 supports the increased safety heater body 20, thereby preventing the support plate 35 from moving and effectively improving the stability of the support plate 35 when it is supported.
[0035] Working principle: First, pull the handle 42 upwards. When the handle 42 is pulled, it will cause the spring plate 43 to slide along the slide groove 41. When the spring plate 43 slides, the spring at the top will be compressed. The locking rod 44 will also move synchronously with the movement of the handle 42. At this time, the locking rod 44 will separate from the locking groove 33 when it moves upwards. When the locking rod 44 separates from the locking groove 33, the angle between the rotating column 31 and the side plate 32 will be unlocked. The side plate 32 will rotate downwards around the rotating column 31 due to gravity. The support plate 35 will swing synchronously with the swing of the side plate 32. The support plate 35 will move in a flexible manner. When the center of column 34 rotates, the symmetrical side plate 32 will rotate synchronously. At this time, the symmetrical side plate 32 will change from its original horizontal state to a vertical state. When the side plate 32 becomes vertical, the handle 42 is released. At this time, the spring at the top of the spring plate 43 will push the spring plate 43 downward. The spring plate 43 will drive the locking rod 44 to move downward and insert into the upward opening of the locking groove 33. The locking groove 33 will change the opening orientation as the side plate 32 rotates. Then, the symmetrical support plate 35 is adjusted to a flat state. At this time, the increased safety heater body 20 can be supported in the mine for heating using the symmetrical support plate 35.
