Description

Technical Field

[0001] This utility model relates to the technical field of testing equipment for the production of physiotherapy beds, and in particular to a drop detection device for the production of physiotherapy beds. Background Technology

[0002] In the production process of physiotherapy beds, drop testing is a crucial quality inspection step. Its core purpose is to simulate the unexpected impacts that the physiotherapy bed may suffer in actual use, transportation, and handling scenarios, thereby verifying the product's structural strength, durability, and safety.

[0003] Current drop testing devices for physiotherapy beds use a flip-up mechanism on the shelf to drop objects onto a lower surface. However, this method is only suitable for smaller shelves. When accommodating larger products, the shelf area increases, and the flipping mechanism often lacks sufficient space for the flipping action. Therefore, it is unsuitable for larger physiotherapy beds. Furthermore, the adjusting screw used for positioning the product has a fixed position, which hinders the placement of the physiotherapy bed. Therefore, optimization and improvement are needed to develop a device suitable for drop testing of physiotherapy beds. Utility Model Content

[0004] In view of the above-mentioned technical problems, this utility model provides a drop detection device for the production of physiotherapy beds. It changes the rotation direction of the placement plate to meet the drop test requirements of the physiotherapy bed. The design of the limiting component has a movable function for the position of the adjusting screw and the limiting pressure plate, which facilitates the operation of placing items on the placement plate during the test. The horizontal position of the limiting pressure plate has an adjustment function, thereby meeting more usage needs.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A drop detection device for the production of physiotherapy beds is characterized by comprising a drop surface, a lifting mechanism, a lifting frame, a rotating mechanism, a shelf, and a limiting component.

The moving block is located in the moving slot and one end of the moving block extends out of the moving slot and is fixedly connected to the lifting frame by screws.

[0006] The rotating mechanism includes a rotating motor and a rotating rod. The rotating motor is mounted on the lifting frame via a motor mount. The output end of the rotating motor is connected to one end of the rotating rod. The rotating rod passes through and extends out of the lifting frame, and a bearing is provided at the connection between the rotating rod and the lifting frame. A shelf is fixed on the rotating rod.

[0007] The limiting assembly consists of a fixed block, a support rod, a positioning part, a telescopic adjusting rod, a mounting block, an adjusting screw, and a limiting pressure plate. The fixed block is fixedly mounted on the lifting frame, the bottom of the support rod is fixedly mounted on the fixed block, the upper end of the support rod is provided with a positioning part, one end of the telescopic adjusting rod is connected to the positioning part, and the other end is connected to the mounting block. The adjusting screw is internally threaded through a threaded hole on the mounting block, and a limiting pressure plate is provided at the bottom of the adjusting screw.

[0008] The positioning part includes a positioning block and a positioning bolt. The positioning block is fitted onto the support rod, and the positioning bolt is connected to the threaded hole provided on the positioning block.

A lead screw 23 is installed in the movable groove on the fixed frame 21 via a bearing, and one end of the lead screw 23 is connected to the output end of the drive motor 22. A movable block 24 is threadedly connected to the lead screw 23. The movable block 24 is located in the movable groove, and one end of the movable block 24 extends out of the movable groove and is fixedly connected to the lifting frame 3 by screws. The guide hole on the movable block 24 is penetrated by a guide post 25, which is mounted on the fixed frame 21 and guides the movement of the movable block 24.

[0019] like Figure 3 A set of rotating mechanisms is provided at both ends of the lifting frame 3. The rotating mechanism includes a rotating motor 41 and a rotating rod 42. The rotating motor 41 is mounted on the lifting frame 3 through a motor base. The output end of the rotating motor 41 is connected to one end of the rotating rod 42. The rotating rod 42 passes through the lifting frame 3 and extends out. A bearing is provided at the connection between the rotating rod 42 and the lifting frame 3. A storage plate 5 is fixed on the rotating rod 42.

[0020] like Figure 4 The lifting frame 3 is equipped with a limit assembly, which consists of a fixed block 61, a support rod 62, a positioning part, a telescopic adjusting rod, a mounting block 651, an adjusting screw 652, and a limit pressure plate 653. The fixed block 61 is fixedly mounted on the lifting frame 3, the bottom of the support rod 62 is fixedly mounted on the fixed block 61, and the upper end of the support rod 62 is provided with a positioning part to connect with the telescopic adjusting rod. The positioning part includes a positioning block 631 and a positioning bolt 632. The positioning block 631 is fitted onto the support rod 62.

[0021] The telescopic adjustment rod includes a fixed rod 641, an adjustment rod 642, and a fixing bolt 643. One end of the fixed rod 641 is fixed to the positioning block 631 of the positioning part, and the other end of the fixed rod 641 is provided with a fixing hole.

[0023] Example 2

[0024] When using this utility model, the staff places the physiotherapy bed above the two sets of storage boards 5, in the middle position, and places the item to be tested, such as... Figure 5 As shown, by operating the positioning bolt 632, its inner end is no longer in contact with the inner wall. Then, the adjusting screw 652 and the limiting pressure plate 653 can be rotated onto the lifting frame 3, so that the physiotherapy bed is not affected by the limiting component when placed on the placement plate, making the placement operation easier.

[0025] After placement, the adjusting screw 652 and the limiting plate 653 are moved to the top of the item. Then, by rotating the adjusting screw 652, the limiting plate 653 moves down to press down on the item, limiting the item to be tested. The length can be adjusted by operating the telescopic adjusting rod, so that the horizontal position of the limiting plate can also be adjusted to meet more usage needs and enhance practicality.

[0026] In this invention, the physiotherapy bed to be tested is placed on two sets of placement boards 5. Typically, the test requires the bed to be raised 60cm and then dropped. During the drop, the two sets of placement boards 5 are controlled by their respective rotation mechanisms to rotate downwards from the middle position of the two sets of placement boards 5, thus allowing the object to be dropped. This solves the problem that the existing method of flipping placement boards is not suitable when the test object is large.
