Technical Field

[0001] The utility model relates to the technical field of testing equipment, in particular to a cable retention force testing machine for a power strip. Background Art

[0002] A power strip is a multi-socket with wires, also known as a power strip, or a wire extension assembly or extension cord socket. A power strip refers to a removable multi-socket with power cords and plugs. It can connect more than one power plug, saving both space and wiring.

[0003] See also Figure 1 , is an existing power strip, which is provided with a plurality of sockets, and the power of each socket comes from the cable on the power strip. It can be seen that the stability of the cable is particularly important; however, the power strip often needs to be moved in actual applications. If the connection between the cable and the power strip is unstable, it is very easy to cause the connection between the cable and the power strip to loosen during the movement, thereby causing the power strip to malfunction and become unusable. In order to ensure that each batch of power strips shipped from the factory meets the requirements of the GB2099.1 / GB2099.7 / IEC60884 safety standards, it is necessary to conduct random inspections on the power strips to test the stability of the cables in each power strip. The existing inspection work is mostly performed manually, which is not only inefficient but also has poor inspection accuracy.

[0004] Therefore, it is necessary to provide a technical solution to solve the above problems. Utility Model Content

[0027] In order to more clearly illustrate the technical solution of the utility model, a preferred embodiment is provided below. Figure 1 to Figure 4 , a cable retention force testing machine for a power strip 11, comprising a frame 1, a support plate 2, an eccentric wheel 3, a driver 4, a weight 5, a controller, and a counter 6, wherein:

[0028] An eccentric rod 7 is eccentrically connected to the eccentric wheel 3, and the eccentric rod 7 is rotatably arranged on the frame 1. The driver 4 is installed on the frame 1, and is used for driving the eccentric rod 7 to rotate; the support plate 2 is arranged above the eccentric wheel 3, one end of which is rotatably connected to the frame 1, and the other end abuts against the eccentric wheel 3, and a fixing component 8 for fixing the power strip 11 is provided on the support plate 2; the weight 5 is installed on the cable of the power strip 11; the counter 6 and the controller are both installed on the frame 1, and the counter 6 and the driver 4 are both electrically connected to the controller.

[0029] The working process of the cable retention force tester of the power strip 11 involved in the utility model is as follows: the power strip 11 is fixed on the support plate 2 by using the fixing assembly 8, and then one end of the support plate 2 is driven to swing up and down by the rotation of the eccentric wheel 3, and under the action of the weight 5, the cable of the power strip 11 will generate a high and low pulling force, thereby simulating the action of the user pulling the power strip 11, and the counter 6 records the number of rotations of the eccentric wheel 3. After the number of rotations of the eccentric wheel 3 reaches the set value, if the socket on the power strip 11 can still be powered on normally, it proves that the quality of the power strip 11 meets the standard. The design of this application realizes the fully automatic detection of the quality of the power strip 11, reduces the amount of manual labor, and improves the detection efficiency and detection accuracy, ensuring that the power strips shipped from the factory meet the requirements of the GB2099.1 / GB2099.7 / IEC60884 safety standards.

[0030] In this embodiment, the fixing assembly 8 includes two bolts 8a and two L-shaped clamping plates 8b. The horizontal section of the clamping plate 8b is in contact with the top surface of the support plate 2, and a strip hole is provided on the horizontal section. The bolt 8a passes through the strip hole and is threadedly connected to the support plate 2. The bolt head of the bolt 8a is in close contact with the horizontal section of the clamping plate 8b. In actual application, the staff can place the power strip 11 between the two clamping plates 8b, and then loosen the bolt 8a to allow the clamping plate 8b to move. After the two clamping plates 8b cooperate to clamp the power strip 11, the bolt 8a is used to re-lock the clamping plate 8b to fix the power strip 11 on the support plate 2.

[0031] Furthermore, an anti-skid pad is provided on the vertical section of the clamping plate 8b. Preferably, the anti-skid pad is made of rubber material. The above design can increase the friction between the clamping plate 8b and the power strip 11, avoid relative movement between the power strip 11 and the clamping plate 8b, and thus improve the detection accuracy.

[0032] In this embodiment, a through hole 2a is formed in the middle of the support plate 2, and the through hole 2a is located between the two clamping plates 8b; the cable of the power strip 11 passes through the through hole 2a. The above design can increase the contact area between the power strip 11 and the support plate 2, and improve the stability of the power strip 11 during the detection process.

[0033] In this embodiment, a roller 2b is provided at the bottom of the support plate 2, and the roller 2b is in contact with the eccentric wheel 3. With the above design, the eccentric wheel 3 can be prevented from wearing the support plate 2.

[0034] In this embodiment, a moving block 2c is provided at the bottom of the support plate 2, and the moving block 2c is connected to the support plate 2 in an adjustable position, and the roller 2b is connected to the moving block 2c. Preferably, the moving block 2c can be set as a structure that can be adjusted up and down, or can be set as a horizontal adjustment structure that can move along the length direction of the support plate 2. In actual application, by adjusting the position of the moving block 2c, the inclination of the support plate 2 can be changed, and then the inclination of the power strip 11 can be changed, so as to simulate different states of the power strip 11 when in use and improve the detection accuracy.

[0035] In this embodiment, a speed regulator 9 is provided on the frame 1, and the speed regulator 9 is electrically connected to the controller. In actual application, the speed regulator 9 can change the speed of the output shaft of the driver 4, that is, change the rotation speed of the eccentric wheel 3, and then change the lifting speed of the power strip 11, so as to simulate different states of the power strip 11 when in use and improve the detection accuracy.

[0036] In this embodiment, a time relay 10 is installed on the rack 1, and the time relay 10 is electrically connected to the controller. In actual application, the time relay 10 is used to control the on and off of the circuit system.

[0037] The above description is only a preferred embodiment of the present invention, and its structure is not limited to the shapes listed above.
