Due to the particularity of PTC electric heaters, they are in a long-term high temperature, high pressure, high current and other environments during the use of electrical appliances. The special environment determines the importance of their electrical safety. Therefore, the industry regards electrical safety as a necessary content and key quality indicator for shipment and factory inspection, especially the stable performance of the heater after heating to a certain temperature.

[0003] At present, conventional testing equipment mostly electrically connects the PTC electric heater to the test equipment through a wiring assembly. However, when actually testing the PTC electric heater, it is necessary to manually place the PTC electric heater and then dock it with the equipment. The equipment testing efficiency is low and wastes manpower.

[0004] Therefore, it is necessary to design a convenient and quick-connect PTC electric heater temperature testing device. Utility Model Content

DETAILED DESCRIPTION

[0020] 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.

[0021] Example 1

[0022] like Figures 1 to 5 As shown, the utility model provides a PTC electric heater temperature test device, which specifically includes a workbench 1, a temperature measuring box base 2, a push-pull rod 3, a long slip ring 4, a stand 5, a turntable 6, a motor 7, a mounting seat 8, an elastic pad 9 and a fixed joint 10;

[0023] Among them, the front side of the workbench 1 is equidistantly fixedly provided with a temperature measuring box base 2, a push-pull rod 3 is slidably penetrated by a raised block on the rear side of the temperature measuring box base 2, a long slip ring 4 is fixedly provided at the end of the push-pull rod 3 away from the temperature measuring box base 2, and a vertical block 5 is slidably provided inside the slip ring. A turntable 6 is rotatably provided at the workbench 1 near the push-pull rod 3, a vertical block 5 is fixedly provided on the outer side of the turntable 6, a motor 7 is fixedly provided on the lower side of the turntable 6, and the rotating shaft of the motor 7 is fixedly connected to the central axis of the turntable 6. A mounting seat 8 is fixedly provided at one end of the push-pull rod 3 in the temperature measuring box base 2, and an opening is opened on the vertical surface of the mounting seat 8 at the end away from the push-pull rod 3, and there is no vertical surface on the end of the mounting seat 8 close to the push-pull rod 3. A fixed joint 10 is provided at the position facing the raised block on the rear side of the temperature measuring box base 2 and the mounting seat 8, which is used to realize automatic docking between the heater and the test equipment;

[0024] The inner side of the mounting seat 8 is provided with an elastic pad 9 for stably placing the heater connector.

[0025] In the present utility model, the staff puts the PTC heater plug into the mounting seat 8. The inner side of the mounting seat 8 is provided with elastic pads 9. The plug is squeezed and fixed by the elastic pads 9 in the mounting seat 8 to limit the movement of the PTC heater plug in the mounting seat 8. Then the staff presses the power switch. At the beginning, the position of the block 5 is close to the temperature measuring box base 2. The motor 7 rotates half a circle, and the turntable 6 and the block 5 on the turntable 6 rotate half a circle. The position of the block 5 is away from the temperature measuring box base 2. The block 5 drives the slip ring away from the temperature measuring box base 2 and moves horizontally relative to the slip ring in the slip ring. The slip ring pulls the push-pull rod 3 fixed thereto to slide to the outside of the temperature measuring box base 2. The mounting seat 8 fixed thereto drives the PTC heater plug to approach the fixed joint 10 and assemble Yes, when the rated time is reached, the motor 7 rotates half a circle, and the turntable 6 and the block 5 on the turntable 6 rotate half a circle, and the position of the block 5 is close to the temperature measuring box base 2, and the block 5 drives the slip ring to approach the temperature measuring box base 2 and moves horizontally relative to the slip ring in the slip ring, and the slip ring presses against the push-pull rod 3 fixed thereto and slides into the temperature measuring box base 2, and the mounting seat 8 fixed thereto drives the PTC heater plug away from the fixed joint 10. Such a design can not only make the PTC electric heater automatically power off after a rated temperature test time is set and reached, but also automatically move the plug of the PTC electric heater away from the fixed joint 10, which not only increases the safety factor of the equipment but also reduces the labor intensity of the staff to a certain extent.

[0026] Example 2

[0027] like Figure 1 , Figure 2 and Figure 4 As shown, on the basis of Example 1, it specifically includes a fixed seat 11, a heat-insulating cover 12 and a temperature measuring rod 13. The fixed seats 11 are symmetrically fixed on the front and rear sides of the temperature measuring box base 2, and a heat-insulating cover 12 is rotatably provided between the front and rear fixed seats 11. The two heat-insulating covers 12 are symmetrical, and a large rectangular hole is opened on the heat-insulating cover 12. A temperature measuring rod 13 is fixedly provided on the rear side of the heat-insulating cover 12 on one side, and the probe of the temperature measuring rod 13 extends into the heat-insulating cover 12.

[0028] After the staff has placed the PTC heater and the plug, the staff manually flips up and covers the left and right sides of the insulation cover 12. The two insulation covers 12 and the temperature measuring box base 2 form an enclosed space and can play a role in heat preservation and insulation. With such a design, the temperature measuring rod 13 will not be affected by the external environment when detecting the temperature, so that the measurement result is more accurate. In addition, when testing the temperature of the PTC heater, it will not be affected by the external environment, so that the power required for heating the PTC electric heater is larger, reducing the power consumed when detecting the temperature of the PTC heater.

[0031] like Figure 2 and Figure 3 As shown, based on Example 1, it also specifically includes a limiting protrusion 15, and a plurality of limiting protrusions 15 are fixedly provided on the temperature measuring box base 2.

[0032] The limiting protrusion 15 is arranged on the temperature measuring box base 2 to limit the position of the PTC heater on the temperature measuring box base 2.

[0033] like Figure 2 and Figure 4 As shown, on the basis of Example 1, a fixing clamp 16 is specifically included, and a plurality of fixing clamps 16 are fixedly provided on the front side of the temperature measuring box base 2 and on the side close to the push-pull rod 3.
