Description
Technical Field

Low temperature impact tester is widely used in the field of socket and plug production. It is a test device for instantaneous cracking of plugs after low temperature.
[0003] The low temperature impact tester is used in conjunction with a low temperature box. The equipment should be placed on a sponge rubber pad and placed in a low temperature box before and during the test. At the end of this time, each plug is placed in the correct position in turn, and the drop weight is allowed to fall for impact. The same plug should be subjected to 4 consecutive impacts. Between each impact, the sample should be rotated 90°. After the test, the plug is restored to room temperature and then inspected. A qualified plug should have no cracks visible under normal vision after the low temperature impact test.
[0004] The existing low-temperature impact tester uses a handbrake to control the falling timing of the drop hammer. The handbrake is connected to the tester through a long connecting line. When the tester is idle or moved, the handbrake is inconvenient to place. When idle, the connecting lines are easily scattered and cause a messy environment. When moving, the connecting lines and handbrake need to be specially freed up to take, which is extremely inconvenient. Utility Model Content

[0022] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.
[0023] Example: Please refer to Figure 1-4 , a plug instantaneous cracking test device after low temperature, comprising a base 1, a fixed column 2, a positioning column 3, an adjustment plate 4 and a connecting plate 5. Two fixed columns 2 are fixedly connected to the base 1, and the upper ends of the two fixed columns 2 are fixedly connected to the connecting plate 5 respectively. An adjustment plate 4 is provided between the base 1 and the connecting plate 5, and the fixed column 2 passes through the adjustment plate 4 and cooperates with the adjustment plate 4, that is, a through hole that is clearance-matched with the fixed column 2 is provided on the adjustment plate 4, and the adjustment plate 4 is connected to the fixed column 2 through a positioning bolt 41. When the positioning bolt 41 is tightened, the adjustment plate 4 is fixedly connected to the fixed column 2, and when the positioning bolt 41 is loosened, the adjustment plate 4 can be moved up and down on the fixed column 2 to adjust the position. The positioning column 3 passes through the connecting plate 5 and the adjustment plate 4 from top to bottom in sequence, and the connecting plate 5 and the adjustment plate 4 are respectively provided with a through hole that is clearance-matched with the positioning column 3. The positioning column 3 is connected to the connecting plate 5 through an adjusting bolt 51. When the adjusting bolt 51 is tightened, the positioning column 3 is fixedly connected to the connecting plate 5, and when the adjusting bolt 51 is loosened, the positioning column 3 can be moved up and down on the connecting plate 5 to adjust the position. A hooking structure 42 is provided on the adjusting plate 4 at one side of the positioning column 3. The hooking structure 42 is used to hook the drop weight 6 and release the drop weight 6 to make it fall under the action of the hand brake 7. The hooking structure 42 can be made of existing technology. The hooking structure 42 is connected to the hand brake 7 through a connecting line 71, and the connecting line 71 is fixedly connected to the hooking structure 42.
[0024] A placement rack 43 is fixedly connected to the side of the adjustment plate 4. A through hole is provided on the placement rack 43 to match the clearance of the handle of the handbrake 7. The placement rack 43 is used to place the handbrake 7. A wire harness 44 is fixedly connected to the two opposite sides of the adjustment plate 4 and the connecting plate 5, that is, the lower plate surface of the adjustment plate 4 and the upper plate surface of the connecting plate 5 are respectively provided with a wire harness 44. The structure of the wire harness 44 is that baffles are fixedly connected to both sides of an intermediate plate, and the surface of the intermediate plate located between the baffles on both sides is an arc surface 441. The wire harness 44 is used to constrain the connecting wire 71 wound on the wire harness 44 so that it does not fall off. Compared with the two vertical surfaces, the arc surface 441 reduces the friction of the connecting wire 71 when it is wound on the wire harness 44. Further, the wire harness 44 is fixedly connected to the edge lines of the lower plate surface of the adjustment plate 4 and the upper plate surface of the connecting plate 5.
[0025] Working principle of this embodiment: This embodiment provides a plug instantaneous cracking test device after low temperature. When idle or moving, the connecting wire 71 is wrapped around the wire harness 44 on the edge line of the lower plate surface of the adjustment plate 4 and the upper plate surface of the connection plate 5. The handle of the handbrake 7 passes through and is placed on the placement rack 43. The wire harness 44 constrains the connecting wire 71 wrapped around the wire harness 44 so that it does not scatter. The placement rack 43 allows the handbrake 7 to be placed in a place and will not be scattered in other places. Through the wire harness 44 and the placement rack 43, the wire harness 44 and the handbrake 7 will not be scattered around and cause environmental chaos when idle. When moving, the wire harness 44 and the handbrake 7 will not be dragged on the ground and easily tripped or worn, which is convenient for idleness or movement. Furthermore, the plug instantaneous cracking test device after low temperature, through the positioning bolt 41 and the adjusting bolt 51, makes the height of the adjusting plate 4 and the positioning column 3 adjustable.
