Description

Technical Field

[0001] This utility model relates to a fixture for vibration testing of a medical testing workbench. Background Technology

[0002] Vibration testing of medical testing workbenches simulates the mechanical environment that the workbench experiences during transportation or actual use. It confirms whether the workbench can withstand the test of motion or vibration environmental factors, determines whether the design specifications of the medical testing workbench are reasonable, confirms the reliability of the medical testing workbench, screens out defective products in advance before leaving the factory, and evaluates the causes of failure of defective products.

[0003] Medical testing workbenches vary in size due to different specifications. The table size of the vibration table in the laboratory is fixed, making it difficult to adapt to different sizes of medical testing workbenches. If the medical testing workbench is too large, it cannot be installed on the vibration table. There are very few extended vibration fixtures for fixing medical testing workbenches on the market. If testing is required, it is necessary to replace it with a vibration table with higher power consumption and a larger table, which increases the testing cost. Utility Model Content

[0004] The purpose of this invention is to provide a fixture for vibration testing of medical testing workbenches. This fixture can clamp medical testing workbenches of different sizes and has high versatility.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A fixture for vibration testing of a medical testing workbench is disclosed. The fixture is an extended platform comprising four support columns with fixed bases, four transverse beams, and two longitudinal beams. The four transverse beams are arranged in parallel at intervals on the two parallel longitudinal beams and are fixedly intersected with the longitudinal beams to form a platform for placing the sample. The intersections of the two middle beams with the longitudinal beams are fixedly supported by the support columns. Each transverse beam has a U-shaped groove, and external fixing bolts can slide freely in the grooves to adjust their position for fixing the medical testing workbench of different sizes to hold the sample.

[0007] Based on the above technical solution, the present invention can be improved as follows:

[0008] The base of this utility model is provided with reinforcing ribs that are connected to the support column.

[0009] The four sides of the support column of this utility model, as well as the bottom surfaces of the transverse beam and the longitudinal beam, are respectively connected to reinforcing strips.

[0010] The "convex"-shaped groove of the utility model runs through the four transverse beams entirely.

[0011] Between the two outermost transverse beams of the utility model and the two longitudinal beams, there are reinforcing ribs which are respectively connected to the inner side surface of the front end of the transverse beam and the outer side surface of the longitudinal beam.

[0012] Compared with the prior art, the technology of the utility model has the following advantages:

[0013] (1) In the utility model, a "convex"-shaped groove is opened on each transverse beam, and the externally connected fixing bolt can freely slide and adjust its position in the groove to fix and clamp the medical test bench specimens of different sizes, achieving the clamping effect that one set of clamps is applicable to multiple specimen models.

[0014] (2) The utility model is an inverted trapezoidal widened platform, wider at the top and narrower at the bottom, enabling the small table vibration test equipment to achieve the purpose of clamping large-sized specimens through this conversion platform, thereby maximizing the detection capacity utilization of the vibration test equipment.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] As Figure 1This embodiment describes a fixture for vibration testing of a medical testing workbench. The fixture is an extended platform. Before clamping the medical testing workbench, the extended platform is fixed to the vibration table surface. The extended platform is fixedly connected to the vibration table surface by four bases 1 at the bottom of four support columns 3 using bolts or other fasteners. The connection between the bases 1 and the support columns 3 is reinforced by reinforcing ribs 2 to increase the strength of the support columns 3. The top of the support columns 3 consists of four transverse beams 5 and two longitudinal beams 6 forming an installation platform. The four transverse beams 5 are arranged in parallel at intervals on the two parallel longitudinal beams 6. The transverse beams 5 and the longitudinal beams 6 are cross-fixed to form an installation platform for placing the sample. The four support columns 3 are respectively fixedly supported at the intersection of the two middle beams and the longitudinal beams. To strengthen the beams, reinforcing strips 4 are connected to the four sides of each support column 3 as well as to the bottom surfaces of the transverse beams 5 and the longitudinal beams 6. Each of the four transverse beams has a U-shaped groove 8 that runs through the entire transverse beam. The external fixing bolts can be freely adjusted in the grooves to fix the sample. To enhance the strength of the outer beams of the widened platform, reinforcing ribs are provided between the two outermost transverse beams and the two longitudinal beams. The reinforcing ribs are fixedly connected to the inner side of the front end of the transverse beams and the outer side of the longitudinal beams, respectively.

[0020] like Figure 2 As shown, the medical testing workbench sample 11 is placed on the widened platform. The external fixing bolt 9, with its head facing down, passes through the U-shaped groove of the transverse beam, while its screw, facing up, passes through the opening slot of the external arched pressure plate 10. One end of the arched pressure plate 10 presses against the edge of the sample 11, and the other end presses against the beam. Finally, the sample 11 is fixed by tightening the nut 12. Because the U-shaped groove runs through the entire transverse beam, the bolt 9 can move freely within the U-shaped groove to accommodate samples of different sizes.

[0021] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
