Description
Technical Field
[0001] This utility model relates to the field of experimental equipment technology, and in particular to a laboratory table with features to prevent accidental electric shock. Background Technology
[0002] Laboratory tables are used in laboratories for various experimental operations, mainly in chemistry, physics, and biology experiments. To improve the corrosion resistance, high temperature resistance, and wear resistance of laboratory tables, the tabletops are usually made of phenolic resin boards or epoxy resin boards. The bottom of the tabletop is fixed by metal legs. The upper part of the laboratory table is also equipped with a power socket for easy access to experimental tools. During experiments, it is often necessary to move the cables of experimental tools. Due to the lack of cable fixing structures, the excess cable length usually piles up on the upper part of the tabletop. Moving experimental tools moves the cables, which in turn moves other experimental tools, easily exposing conductive circuits and posing a risk of accidental electric shock to the user.

[0020] This utility model relates to a laboratory table with features to prevent accidental electric shock, such as... Figure 1-3 As shown, the apparatus includes a tabletop 1 and table legs 2 located on both sides of the bottom of the tabletop 1. A power socket 3, connected to an external power source, is located on one side of the upper end of the tabletop 1. The power socket 3 is electrically connected to the experimental tools. Multiple gripper mechanisms 4 are located on the upper end of the tabletop 1. Each gripper mechanism 4 includes two clamps 41, a transmission screw 42, and a fixed housing 43. The transmission screw 42 is connected to the two clamps 41 to move the clamps 41. The transmission screw 42 is located inside the fixed housing 43, which is located on the upper end of the tabletop 1. The conductive cables of the experimental tools pass between the two clamps 41. A storage cabinet 5 is located on one side of each table leg 2. The tabletop 1 and table legs 2 are installed on both sides of the bottom of the tabletop 1, with the bottom of the table legs 2 standing on the ground and the top of the table legs 2 facing the tabletop. 1. Support: During the experiment, the experimental tool is placed on the upper part of the table 1. The conductive cable of the experimental tool is then passed between the two clamps 41. The excess length of the conductive cable is pulled to the rear of the gripper mechanism 4, and the conductive cable of the experimental tool is electrically connected to the power socket 3. The transmission screw 42 rotates in the fixed housing 43, causing the two clamps 41 to move closer to each other. After the conductive cable is clamped and fixed on both sides by the two clamps 41, the excess length of the conductive cable is separated from the experimental tool and blocked behind the gripper mechanism 4. Thus, when the user moves the experimental tool, the accumulated conductive cable will not be moved, thereby avoiding the problem of exposed conductive circuit. This solves the problem that the conductive cable of the experimental tool is easy to move and exposes the conductive circuit.
[0021] In an embodiment of this utility model, first mounting posts 7 perpendicular to each other are respectively provided on both sides of the upper end of the tabletop 1, and a mounting plate 8 is connected between the two first mounting posts 7. By setting the first mounting posts 7 and the mounting plate 8, the mounting plate 8 is installed between the two first mounting posts 7, so that the mounting plate 8 is perpendicular to the tabletop 1.
[0022] In this embodiment of the utility model, the power socket 3 is mounted on the mounting plate 8. The mounting plate 8 is also equipped with an indicator 9 and a circuit breaker 10 that are electrically connected to the power socket 3. The power socket 3, the indicator 9, and the circuit breaker 10 face the table 1. By setting the indicator 9 and the circuit breaker 10, the indicator 9 is used to display the current, voltage, resistance, and other values of the power socket 3, and the circuit breaker 10 can easily control the power supply to and from the power socket 3.
[0023] In an embodiment of this utility model, an arc-shaped groove 11 is provided on the tabletop 1. By setting the arc-shaped groove 11, the upper horizontal surface of the tabletop 1 becomes a concave-convex surface, thereby increasing the friction of the conductive cable of the experimental tool on the tabletop 1 and preventing the conductive cable of the experimental tool from sliding on the tabletop 1.
[0024] In an embodiment of this utility model, a second mounting post 12 is provided on both sides of the bottom of the arc-shaped groove 11. The top of the two second mounting posts 12 is connected to a sliding bracket 13 that is slidably connected to the gripper mechanism 4. By setting the second mounting posts 12 and the sliding bracket 13, the sliding bracket 13 is horizontally set above the arc-shaped groove 11 through the second mounting posts 12. A space is left between the sliding bracket 13 and the arc-shaped groove 11 for the conductive cable to pass through.
[0025] In this embodiment of the utility model, the fixed housing 43 is disposed on the top of the sliding bracket 13. The bottom of the fixed housing 43 is symmetrically provided with two sliding grooves 14 about the sliding bracket 13, which are slidably connected to the clamp 41. The two sides of the clamp pass through the sliding grooves and are slidably connected to the two sides of the sliding bracket 13. By providing the sliding grooves 14, the bottom of the clamp 41 extends through the sliding grooves 14 to the top of the arc-shaped groove 11. By the two sides of the clamp 41 passing through the sliding grooves 14 and the two sides of the sliding bracket 13, the sliding stability of the clamp 41 is improved.
[0026] In this embodiment of the utility model, the clamp 41 is a U-shaped bracket. The bottom of the clamp 41 extends through the sliding groove 14 to the top of the arc-shaped groove 11 and is provided with an anti-slip sleeve 15. The inner side of the clamp 41 is provided with a limiting plate 16 that slides and engages with the bottom of the sliding bracket 13. By providing the anti-slip sleeve 15, the stability between the clamp 41 and the conductive cable is increased. By providing the limiting plate 16, the upper end of the limiting plate 16 is slidably connected to the bottom of the sliding bracket 13, thereby improving the stability of the limiting plate 16 sliding on the sliding bracket 13.
[0027] In an embodiment of this utility model, the transmission screw 42 is provided with two threads that are symmetrical about the middle and have opposite transmission directions. The two ends of the transmission screw 42 are respectively connected to the upper ends of two clamps 41. By setting the above structure, when the transmission screw 42 rotates, it will drive the two clamps 41 to move closer to each other and further away from each other along the length direction of the transmission screw 42.
[0028] In an embodiment of this utility model, one end of the transmission screw 42 extends to the outside of the fixed housing 43 and is provided with a turntable 17. By providing the turntable 17, the user can easily rotate the transmission screw 42.
[0029] In an embodiment of this utility model, a rubber pad 6 is provided on the upper end of the tabletop 1. By providing the rubber pad 6, the friction resistance and insulation of the upper end of the tabletop 1 are improved.
[0030] In use, first, place the experimental tool on the table 1, put the conductive cable of the experimental tool into the arc-shaped groove, and pass it between the two clamps 41. Then, pull the excess length of the conductive cable to the back of the gripper mechanism 4, and connect the conductive cable of the experimental tool to the power socket 3. The transmission screw 42 rotates in the fixed housing 43, causing the two clamps 41 to move closer to each other along the length of the slide 14. After the conductive cable is clamped and fixed on both sides by the two clamps 41, the excess length of the conductive cable is separated from the experimental tool and blocked behind the gripper mechanism 4 and the sliding bracket. The current, voltage, resistance and other values of the power socket 3 are displayed by the indicator instrument 9, and the power on and off of the power socket 3 can be easily controlled by the circuit breaker 10.
