[0020] 11 PLC control cabinet, 12 counterweight, 13 support rod Detailed Embodiments

[0021] The specific embodiments described herein are only used to explain the technical solution of this patent, rather than limiting the disclosed technical solution. In addition, it should be noted that for the sake of convenience of description, only parts related to the technical solution of the present application are shown in the drawings, rather than all the structures.

[0022] Before discussing the exemplary embodiments in more detail, it should be mentioned that if the structures of the device components and / modules mentioned in the embodiments are not described in detail, those skilled in the art can understand them according to the existing public technologies or commercially available products.

[0023] Reference Figure 1, the pet toy bite force and tensile force testing device provided in this embodiment includes a test bench 1, an upper canine tooth mold 2, a lower canine tooth mold 3, a load block 4, a cylinder 5, a guide rod 6, a top plate 7, a fixing ring 8, a tensile force sensor 9, an electric lead screw 10, and a PLC control cabinet 11. The lower canine tooth mold 3 is arranged at one end of the test bench 1, and the upper canine tooth mold 2 is connected to the lower canine tooth mold 3 in an oral cavity shape. There are multiple guide rods 6, which are vertically arranged on the test bench 1 and are located on both sides of the lower canine tooth mold 3. The load block 4 is horizontally sleeved on the guide rod 6, and the top plate 7 is fixed at the top of the guide rod 6. The cylinder 5 is arranged on the test bench 1, and the telescopic rod of the cylinder 5 is connected to the bottom surface of the load block 4. The electric lead screw 10 is horizontally arranged on the test bench 1, and a tensile force sensor 9 and a fixing ring 8 are arranged on the slider of the electric lead screw 10. The PLC control cabinet 11 is used to control the cylinder 5 and the electric lead screw 10.

[0024] The load block 4 is selected with a standard weight of 100 pounds. Several additional counterweight blocks 12 can be configured, such as 5 standard weight blocks of 50 pounds. During the test, they can be loaded onto the load block 4 as needed.

[0025] Preferably, a safer setting is adopted. For example, a row of through holes is provided in the middle section of each guide rod 6, and pin holes are provided on the side walls of each counterweight block 12. The counterweight block 12 is horizontally sleeved on the guide rod 6, and the positions of the pin holes are adapted to the positions of the through holes. During the test, according to the configuration requirements, pins are inserted into the pin holes of the counterweight blocks that do not need to bear the load and the through holes on the guide rod to adjust the load borne by the load block 4.

[0026] Another counterweight structure is that two or more support rods 13 are additionally provided. A row of through holes is provided in the middle section of each support rod 13, and the support rods 13 are arranged in parallel between the guide rods 6. The counterweight block 12 is horizontally sleeved on the support rods 13 and the guide rod 6, and pin holes are provided at the corresponding positions of the through holes of the support rods 13 on the side walls of the counterweight block 12.

[0027] The drive of the electric lead screw 10 is preferably a servo motor.

[0028] The performance of pet toys is a simulation test that is stricter than the actual use situation. After loading a set load on the pet toy, bite and bite-and-pull experiments are carried out at a certain speed within a specified range to test the durability of the pet toy body and its connecting ropes, etc.

[0029] During the test, the pet toy is bitten with the front teeth or side teeth of the canine teeth. If there is a pulling rope, the pulling rope is buckled on the fixing ring. Select the weight of the counterweight block according to the requirements, insert a pin into the side of the extra counterweight blocks that do not need to be loaded, and fix them to the guide rod or support rod. Set the number of tests and the frequency.

[0030] Start the cylinder, and the cylinder rod rises to lift the load block and the unfixed counterweight block; then start the servo motor to start the test. The cylinder pushes the load up and down to perform a fatigue test on the sample bitten by the dog teeth; when testing a toy with a pulling rope, the cylinder drops and presses on the dog teeth, and the servo motor starts to simulate the violent biting of a pet biting the toy under the specified force and speed. When the set number of times is completed and the sample has no deformation or cracking, the test passes; otherwise, the test fails.

[0031] The above is the test for the bite strength fatigue of pet toys, and the strength level can be changed by loading the load weight. Although the test device of the above embodiment is a semi-automatic test equipment, it also meets the requirements of test repeatability and reproducibility. The structure and operation are very simple, safe and reliable, low-cost, and small in floor area.
