Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a stroller handle strength testing machine. Background Technology

[0002] The stroller handle strength test aims to evaluate its structural strength and durability under repeated lifting, pressing or twisting operations, ensuring that the handle does not break, deform or loosen under normal use and extreme conditions, thereby effectively protecting the safety of infants and young children.

[0003] Current testing equipment applies load by fixing the stroller handle to a sliding frame and then applying pressure or pulling. However, when dealing with different stroller models, the relative position between the pressure block and the handle needs frequent adjustment to ensure the balance and stability of the applied load. Furthermore, if a unilateral force test is required, the pressure block on the other side must be disassembled and readjusted, which is cumbersome and inefficient.

[0004] Therefore, there is an urgent need for a stroller handle strength testing machine to improve testing adaptability and ease of operation. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a stroller handle strength testing machine.

[0006] The technical implementation scheme of this utility model is as follows: a stroller handle strength testing machine includes a base, a mounting frame, guide rods, a lifting assembly, a movable plate, a two-way lead screw, a motor, a movable block, a mounting seat, a fastening plate, a latch, and a snap-fit ​​component. The mounting frame is provided on the base, and a through groove is formed on the mounting frame. Symmetrically arranged guide rods are arranged within the through groove, and a lifting assembly is located between the two guide rods. A movable plate is provided on the movable component of the lifting assembly, and both ends of the movable plate are slidably connected to the guide rods on the same side, with the two ends of the movable plate connected together. The device features a rotating bidirectional lead screw, and a motor with its output end connected to the shaft end of the bidirectional lead screw is mounted on the movable plate. A movable block is threaded onto each side of the bidirectional lead screw, and a mounting base is mounted on each movable block. Each mounting base is hinged with a fastening plate for mounting a sensor and for locking the position of the stroller's handle. The fastening plate has a groove, and a latch is slidably and rotatably mounted between the upper and lower sides of the groove. The bottom end of the latch abuts against the corresponding fastening plate, and a locking element for fixing the position is provided between the fastening plate and the corresponding mounting base.

[0007] Furthermore, the snap-fit ​​component includes a snap-fit ​​block and an elastic element. Each snap-fit ​​plate has a snap-fit ​​block that engages with the corresponding mounting base, and an elastic element is provided between the snap-fit ​​block and the corresponding snap-fit ​​plate.

[0008] Furthermore, it also includes support columns, electric push rods, slide rails, and pressure rods. A support column is set on each side of the base platform, and an electric push rod with its telescopic end facing downward is installed on the support column. A slide rail is set on the telescopic end of the electric push rod, and a pressure rod slides symmetrically between the two slide rails.

[0009] Furthermore, it also includes buffer pads, with buffer pads provided on both the upper and lower sides of the pressure rod.

[0010] Furthermore, it also includes magnets, with magnets on both sides of the pressure rod that magnetically engage with the slide rail.

[0011] Furthermore, it also includes a limit frame, with the limit frame hinged between the two support columns.

[0012] This utility model has the following advantages: 1. By setting two independently adjustable fastening plates, this utility model can achieve both overall force testing of the stroller handle and single-sided force testing using only one fastening plate, meeting diverse testing needs. Furthermore, the fastening plates are equipped with a latch structure, and the angle is quickly locked through snap-fit ​​components (including snap blocks and elastic elements), simplifying the operation process of changing and adjusting the test position and significantly improving testing efficiency. Simultaneously, the device has the functions of securely fixing the stroller handle and real-time pressure monitoring, ensuring uniform force distribution and accurate and reliable data during the testing process.

[0013] 2. This utility model improves the stability of the limit by controlling the height adjustment of the slide rail and the pressure rod through an electric push rod, effectively preventing the stroller body from shifting during the test, creating a safe test area, and thus ensuring the personal safety of the operator.

Detailed Implementation

[0019] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] Example: A stroller handle strength testing machine, such as Figures 1-3As shown, the device includes a base platform 1, a mounting frame 2, guide rods 3, a lifting assembly 4, a movable plate 5, a double-acting screw 6, a motor 7, a moving block 8, a mounting base 9, a fastening plate 10, a latch 11, and a snap-fit ​​component. The base platform 1 serves as the basic support structure for the entire device. A mounting frame 2 is fixedly installed on the rear top of the base platform 1. A through groove is provided on the mounting frame 2, and guide rods 3 are arranged symmetrically on both sides within the through groove. The lifting assembly 4 is located between the two guide rods 3. The lifting assembly 4 can be an electric screw or a cylinder, or other drive components that can precisely control the lifting height. A movable plate 5 is installed on the movable part of the lifting assembly 4. The left and right ends of the movable plate 5 are slidably connected to the guide rods 3 on the same side, thereby ensuring the stability and straightness of the movable plate 5 during the lifting process and preventing deviation or shaking. A double-acting screw 6 rotates between the left and right ends of the movable plate 5. A motor 7, whose output end is connected to the shaft end of the double-acting screw 6, is also fixedly installed on the movable plate 5. A moving block 8 is threaded on each side of the double-acting screw 6. Driven by the mechanism, the two moving blocks 8 on both sides are synchronously driven, so that the two moving blocks 8 can move synchronously in opposite directions when the bidirectional screw 6 rotates, thereby realizing independent adjustment of the test position on the left and right sides. A mounting base 9 is fixedly installed on the moving block 8, and a fastening plate 10 with a sensor is hinged on the mounting base 9. This sensor is a pressure sensor, which is used to monitor the pressure change during the test in real time to ensure the accuracy and reliability of the test data. The fastening plate 10 is also used for locking the position of the handle of the stroller body 21. The fastening plate 10 has a groove, and a latch 11 is slidably and rotatably installed between the upper and lower sides of the groove, so that the latch 11 can slide along the groove and rotate around its own axis. The bottom end of the latch 11 abuts and fits against the corresponding fastening plate 10 to achieve stable clamping and release of the handle of the stroller body 100. A snap-fit ​​is provided between the fastening plate 10 and the corresponding mounting base 9 for position fixing, which is used to lock the angle position of the fastening plate 10 relative to the mounting base 9.

[0021] Therefore, the above-described structure makes the strength testing of the stroller body 100 simpler and more efficient. The two rotatable and adjustable fastening plates 10 allow for flexible adjustment of the testing area to accommodate the specific shape and size of the handles of different stroller body 100 models. Furthermore, the synergistic effect of the snap-fit ​​parts and latches 11 not only ensures the simplicity and stability of the overall assembly process but also greatly facilitates quick replacement and adjustment, significantly improving the equipment's versatility and ease of operation.

[0022] like Figure 3As shown, the snap-fit ​​component includes a snap-fit ​​block 12 and an elastic element 13. A snap-fit ​​block 12 is slidably disposed on each snap-fit ​​plate 10 to engage with the corresponding mounting base 9. An elastic element 13 is disposed between the snap-fit ​​block 12 and the corresponding snap-fit ​​plate 10. In this embodiment, the elastic element 13 is a spring. Through the snap-fit ​​engagement between the snap-fit ​​block 12 and the mounting base 9, the angular position of the snap-fit ​​plate 10 relative to the mounting base 9 is fixed, preventing angular displacement due to vibration or force during testing. The elastic element 13 causes the snap-fit ​​block 12 to automatically spring back after operation, facilitating quick release of the snap-fit ​​plate 10 and readjustment of the angle, thus improving operational efficiency.

[0023] like Figure 1 and Figure 4 As shown, it also includes a support column 14, an electric push rod 15, a slide rail 16, and a pressing rod 17. A support column 14 is provided on each of the left and right sides of the base platform 1. An electric push rod 15 with its telescopic end facing downward is installed on the support column 14. A slide rail 16 is provided on the telescopic end of the electric push rod 15. A pressing rod 17 slides symmetrically back and forth between the two slide rails 16. The electric push rod 15 drives the slide rail 16 and the pressing rod 17 to move downward. This can restrict the position of other parts of the stroller body 100 (such as the frame or seat) during the inspection process, and improve the comprehensiveness of the inspection items.

[0024] like Figure 4 As shown, it also includes a cushioning pad 18. Cushioning pads 18 are provided on both the upper and lower sides of the pressure bar 17. The cushioning pad 18 is usually made of rubber or soft material, which can effectively reduce the rigid contact between the pressure bar 17 and the stroller body 100 and avoid surface damage.

[0025] like Figure 4 As shown, it also includes magnets 19. Magnets 19 that magnetically engage with slide rails 16 are provided on both sides of the pressure rod 17. The magnetic engagement between magnets 19 and slide rails 16 can enhance the stability of the pressure rod 17 during the sliding process.

[0026] like Figure 4 As shown, it also includes a limit frame 20, which is hinged between the two side support columns 14. The limit frame 20 can be rotated and unfolded according to the test requirements, thereby limiting the test area.

[0027] In use, first place the stroller body 21 on the base platform 1, activate the lifting assembly 4, and drive the moving plate 5 to slide up and down along the guide rod 3, thereby adjusting the height of the moving plate 5 and its components relative to the handle of the stroller body 21. Then push the stroller body 21 close to the fastening plate 10, and select one or two fastening plates 10 for testing depending on the testing requirements. After confirming the position, start the motor 7 to drive the bidirectional lead screw 6 to rotate, causing the moving block 8 and connecting components on it to adjust left and right, so that the fastening plate 10 is accurately aligned with the required testing position of the stroller body 21 handle. Next, move the corresponding locking block 12 to slide along the fastening plate 10 and compress the elastic element 13, releasing the locking block 12 from limiting the fastening plate 10 and the mounting base 9. Then, flip the fastening plate 10 to a suitable angle and release the locking block 12. The elastic element 13 resets, causing the locking block 12 to spring back and re-lock into the corresponding position of the mounting base 9, achieving a stable connection between the fastening plate 10, the mounting base 9, and the moving block 8. Then, rotate the latch 11 to release its restriction on the fastening plate 10, and pull out the latch 11. Next, insert the handle of the stroller body 21 into the fastening plate 10, then insert the latch 11 back into its original position and rotate it to fix it, so that the fastening plate 10 and the handle are firmly connected, completing the positioning and fixing of the handle. Next, start the electric push rod 15 to drive the slide rail 16 and the pressure rod 17 to adjust their height, so that the whole is above the base of the stroller body 21. Then, push the two pressure rods 17 to slide along the slide rail 16, and then simultaneously adjust the overall height position of the slide rail 16 and the pressure rod 17, so that the pressure rod 17 and the slide rail 16 contact the base of the stroller body 21, thereby achieving effective restriction around the stroller body 21. At the same time, the cushioning pad 18 contacts the base of the stroller body 21 to prevent damage caused by friction. Then, rotate the limiting frame 20 to a horizontal position to delineate the safety detection area around the device, preventing personnel from accidentally entering the test range and forming a safety red line. After everything is ready, the strength test begins. The lifting assembly 4 is activated, and the up-and-down movement of the movable plate 5 applies a pulling force to the handle of the fixed stroller body 21. During the test, sensors collect the applied pressure data in real time and transmit the data to the control backend for recording and analysis of the test data.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
