[0021] like Figure 1-6 As shown, this utility model discloses a multifunctional subway car door obstacle testing fixture, including an obstacle detection area 1, a non-detection area 3 on one side of the obstacle detection area 1, a tension detection area 2 on the other side of the non-detection area 3, and a fixing plate 4 on the other side of the obstacle detection area 1. By installing the fixing plate 4, fixing rod 5, and fixing sleeve 6, a tension gauge hanging ring 8 can be easily installed on the side of the obstacle detection area 1. The fixing plates 4 are symmetrically distributed. The fixing rod 5 is located on the inner side of the fixing plate 4, and the fixing sleeve 6 is located on the outer side of the fixing rod 5. A frame 7 is located on the side of the fixing sleeve 6, and a tension gauge hanging ring 8 is located on the side of the frame 7. The tension gauge is installed on one side of the obstacle detection area 1. The device includes a hanging ring 8 and a non-detection area 3 on the other side of the obstacle detection area 1. A tensile testing area 2 is installed on the other side of the non-detection area 3. When the door is clamped by an obstacle outside the detection accuracy range, and the door is indicated as closed and locked, the operator connects the tensile testing machine to the tensile testing machine via the hanging ring and pulls the tensile testing machine outward. The machine can pull out the obstacle with a force not exceeding 150N. This combines the needs of obstacle detection and tensile testing into one, integrating two detection functions: door obstacle detection and door clamping and pulling force testing. It has advantages such as portability, optimized work process, improved work efficiency, and reduced one-time procurement cost of tooling. It is also relatively easy to operate during use.

[0022] A rubber sleeve 9 is fitted onto the outside of the tensile testing area 2. A cross plate 14 is provided on the inner side of the rubber sleeve 9. A cross groove 15 is opened on the outer side of the tensile testing area 2. The cross plate 14 is embedded in the cross groove 15. A metal rod 12 is provided on the inner side of the rubber sleeve 9. A magnetic groove 13 is opened on the side of the tensile testing area 2. The magnetic groove 13 is magnetically attracted to the outside of the metal rod 12. By installing the cross plate 14, the cross groove 15, the metal rod 12, and the magnetic groove 13, the cross plate 14 is first embedded in the cross groove 15, and at the same time, the rubber sleeve 9 is installed on the outside of the tensile testing area 2 by strong magnetic attraction.

[0023] The rubber sleeve 9 has a locking block 10 on its inner side, and the locking blocks 10 are evenly distributed. The outer side of the tensile testing area 2 has a locking groove 11, and the locking block 10 is embedded in the inside of the locking groove 11. Due to the installation of the locking block 10 and the locking groove 11, the rubber sleeve 9 can be easily installed and fixed to the outside of the tensile testing area 2 by the squeezing force during installation.

[0024] An inner groove 18 is provided on the side of the obstacle detection area 1. A magnetic absorbing piece 20 is provided on the inner side of the inner groove 18. A rubber back plate 16 is embedded on one side of the obstacle detection area 1, and a rubber front plate 17 is provided on the other side of the obstacle detection area 1. A metal sheet 19 is provided on the inner side of the rubber back plate 16 and the inner side of the rubber front plate 17. The magnetic absorbing piece 20 magnetically attracts the metal sheet 19. Due to the inner groove 18, the rubber front plate 17 and the rubber back plate 16 can be installed on the inner side of the obstacle detection area 1.

[0025] A magnetic rod 21 is provided on the side of the rubber back plate 16, and a metal sleeve 22 is provided on the side of the rubber front plate 17. A through hole 25 is opened on the inner side of the obstacle detection area 1. The magnetic rod 21 passes through the inside of the through hole 25, and the metal sleeve 22 passes through the inside of the through hole 25. The magnetic rod 21 attracts the metal sleeve 22 by magnetic force. Since there is a through hole 25, it is convenient to pass the magnetic rod 21 and the metal sleeve 22 through the inside of the obstacle detection area 1. At the same time, the rubber back plate 16 and the rubber front plate 17 are spliced ​​by strong ferromagnetic attraction.

[0026] The rubber back plate 16 has an extrusion groove 24 on its side and the rubber front plate 17 has an extrusion groove 24 on its outer side. An extrusion block 23 is provided inside the inner groove 18. The extrusion block 23 is embedded inside the extrusion groove 24. By installing the extrusion groove 24 and the extrusion block 23, it is easy to initially install the rubber back plate 16 and the rubber front plate 17 on both sides of the obstacle detection area 1.

[0027] The working principle of this multi-functional subway door obstacle testing fixture is as follows: When using this device, firstly, the side of the obstacle detection area 1 is connected to the side tension detection area 2 through the non-detection area 3. The other side of the obstacle detection area 1 is connected to the fixing sleeve 6 through the fixing rod 5. Moreover, the outside of the fixing sleeve 6 is connected to the tension gauge hanging ring 8 through the frame 7. In order to protect the obstacle detection area 1 and the outside of the tension detection area 2 during the testing process, a protective structure is installed on the outside. First, take out the rubber sleeve 9, in which the inner side of the rubber sleeve 9 is provided with a metal rod 12, a cross plate 14, and a locking block 10. Then, pinch the rubber sleeve 9 and put it on the outside of the tension detection area 2. The cross plate 14 is embedded in the inside of the cross groove 15. At the same time, the metal rod 12 is embedded in the inside of the magnetic groove 13, and the side locking block 10 is embedded in the inside of the locking groove 11. In this way, the rubber sleeve 9 can be installed and fixed on the outside of the tension detection area. After that, take out the rubber back plate 16 and the rubber front plate 17 again. The rubber back plate 16... A metal sheet 19 is provided on the side of the rubber front panel 17. The rubber back panel 16 and the rubber front panel 17 are embedded in the inner groove 18 and attracted by the magnetic suction sheet 20. At the same time, the magnetic suction rod 21 on the inner side of the rubber back panel 16 is spliced ​​with the metal sleeve 22 on the inner side of the rubber front panel 17. In this way, the rubber front panel 17 and the rubber back panel 16 can be installed on the side of the obstacle detection area 1. Finally, when testing is required, the operator only needs to place the obstacle detection area 1 between the door panels. When the door clamps an obstacle that is outside the detection accuracy, and the door is indicated as closed and locked, the obstacle can be pulled out with a force of no more than 150N. The testing requirements are combined into one, integrating two testing functions: door obstacle detection and door clamping and pulling force testing. The tooling integrates two testing functions, which is convenient for testing personnel to carry. Moreover, the multi-functional integrated tooling reduces the one-time purchase cost, optimizes the work process, simplifies the work procedures, reduces the workload of operators, and improves production efficiency. It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
