DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0022] Reference Figure 1-7 A tensile testing mechanism for automobile seat belt production includes a base plate 1, a gantry 11 fixedly mounted on the top of the base plate 1, a downward-facing clamping seat 2 vertically movably mounted on the gantry 11 via a movable plate 3, and an upward-facing clamping seat 2 fixedly mounted on the top of the base plate 1. Each clamping seat 2 is fixedly mounted with a fixing member 21, and a vertically movably adapted movable member 3 is mounted within the fixing member 21. Both ends of the movable member 3 are fixedly mounted with side posts 31, and each side post 31 is movably mounted with a pull plate 4. Both ends of the pull plate 4 are vertically fixed with a clamping column 41 facing the clamping seat 2.
[0023] Among them, vertical grooves 12 are opened on both sides of the gantry 11, and both ends of the movable plate 13 are adapted to be located in the grooves 12. A tension sensor 14 is fixedly installed at the bottom of the movable plate 13, and a downward clamping seat 2 is installed below the tension sensor 14.
[0024] Among them, a clamping cavity is opened in the fixed part 21, and the clamping cavity is adapted to the movable part 3. A plurality of reinforcing columns 30 are fixedly set on the movable part 3, and a reinforcing cavity 211 is adapted to be opened in the clamping cavity corresponding to the reinforcing columns 30. Anti-slip pads are set on the reinforcing columns 30 and the reinforcing cavity 211. Through the adaptation between the reinforcing columns 30 and the reinforcing cavity 211, the clamping effect of the seat belt can be further improved during the process of clamping the seat belt.
[0025] The clamping base 2 has vertical adjustment slots 22 on both sides, and the side posts 31 extend from the adjustment slots 22. The clamping base 2 has first and second slots 23 and 24 on both sides of the adjustment slots 22, and both the first and second slots 23 and 24 are adapted to fit with the clamping posts 41. By clamping the clamping posts 41 in the first and second slots 23 and 24, the pull plate 4 can be fixed in different positions.
[0026] The side column 31 defines a guide cavity 32, and a guide member 42 is provided in the middle of the pull plate 4, corresponding to the guide cavity 32. A spring cavity 33 is provided on one side of the side column 31, housing a spring 5. The other end of each spring 5 is connected to the guide member 42. The matching arrangement between the guide member 42 and the guide cavity 32 enhances the stability of the pull plate 4 during movement.
[0027] In this embodiment, when the user needs to test the tension of the safety belt, he or she only needs to clamp the two ends of the safety belt on the upper and lower clamping seats 2 respectively, and then use the movable plate 13 to drive the upper clamping seat 2 to move upward, so as to achieve the stretching of the safety belt, and the tension can be monitored by setting the tension sensor 14 on the movable plate 13. Since grooves 12 are provided on both sides of the gantry 11, a guide column is fixedly provided in the groove 12 on one side, and a screw rod is rotatably provided in the groove 12 on the other side, and the screw rod is connected to the motor at the top of the gantry 11. The motor can drive the screw rod to rotate, thereby achieving the vertical movement of the movable plate 13. It is worth noting that this is a prior art and therefore will not be described in detail.
[0028] Furthermore, when the user needs to secure the ends of the safety belt to the clamping base 2, they simply pull the pull plates 4 on either side of the clamping base 2 outward. At this point, the latching posts 41 on the pull plates 4 are released from the first latching slots 23, and the springs 5 are stretched. The user then simply moves the side posts 31 outward through the adjustment slots 22, causing the pull plates 4 to move to the second latching slots 24. At this point, the user simply releases the pull plates 4, and the pull plates 4 and latching posts 41 automatically return to their original positions due to the elastic force of the springs 5, causing the latching posts 41 to automatically return to their original positions in the second latching slots 24.
[0029] At this point, the movable member 3 is no longer located in the clamping cavity of the fixed member 21, and the user can now insert the end of the safety belt into the clamping cavity. Finally, the user only needs to re-engage the clamping column 41 in the first clamping groove 23 according to the above steps, thereby re-engaging the movable member 3 in the clamping cavity of the fixed member 21 to achieve clamping of the end of the safety belt.
[0030] When the clamping seats 2 on both sides have completed clamping the ends of the safety belt, the safety belt can be stretched by moving the movable plate 3, and the safety belt tension data can be detected by the tension sensor 14. This is all existing technology, so it will not be described in detail.
[0031] In the utility model, the two ends of the safety belt can be clamped and fixed by the clamping seats 2 on the upper and lower sides, the tension of the safety belt can be detected by the movable plate 13 and the tension sensor 14, and the safety belt can be quickly fixed and clamped by the adaptive clamping between the fixing part 21 and the movable part 3. This clamping method for the end of the safety belt is quick and convenient and easy for users to use.
[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
