[0014] The present invention will be described in further detail below with reference to the accompanying drawings.

[0015] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0016] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0017] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0018] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0019] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0020] Example:

[0021] Figure 1 This is a schematic diagram of the use of a quick pressing device for a pressure sensor calibration seat. Figure 2 This is the main view of the eccentric wheel. Figure 3 This is an angled three-dimensional diagram of the eccentric wheel. Figure 4 This is another angle of the eccentric wheel. Figure 5 It is a top view of the eccentric wheel.

[0022] It includes an eccentric wheel 4, which includes a pillar 403 and a clamping block 401. The lower surface of the clamping block 401 is a spiral surface 402 for clamping the calibration seat, and the A end of the spiral surface 402 is higher than the B end; one end of the pillar 403 is eccentrically connected to the clamping block 401, and the other end is provided with a threaded column 404 for connecting to the calibration seat.

[0023] The pressing block 401 is generally cylindrical in structure.

[0024] The clamping block of the present invention adopts a cylindrical structure and will not scratch workers. A pillar 403 is provided so that the bottom surface of the clamping block 401 is higher than the pressure strip 3 of the calibration seat, which is convenient for gradually compressing the pressure strip 3. The pillar 403 is connected to the calibration seat through a threaded column 404. With the eccentric structure, it can be rotated to rotate the spiral surface 402 away from the pressure strip 3, which is convenient for placing the force transmission sensor. After the placement is completed, the spiral surface 402 is rotated to be located above the pressure strip 3, and then continued to rotate until the spiral surface 402 is at a lower position to compress the pressure strip 3.

[0025] The bottom surface is set as a spiral surface, and the support is set as an eccentric structure. During the rotation process, the high position, such as point A, is first located above the bead 3, and then point B gradually approaches the bead 3 until the bead 3 is pressed tightly. Before use, adjust the height of the support so that the bead 3 can be pressed tightly with one rotation.

[0026] The thread is set to connect with the calibration seat, and can be tightened by utilizing the principle of nut tightening to tighten.

[0027] The surface of the pressing block 401 is provided with a hexagonal hole 406 and a stepped hole 405, both of which are coaxial with the pillar 403. The hexagonal hole 406 is used to match the hexagonal handle to facilitate the operation of the worker, and the stepped hole 405 is convenient for installing the hexagonal handle.

[0028] The calibration seat includes a base 1, a pressure plate 2, and a pressure strip 3. The sensor is placed in a cavity inside the base 1, the pressure plate 2 is pressed on the cavity, and the pressure strips are arranged at both ends of the pressure plate 2 for contacting the eccentric wheel.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are within the scope of the technical solution of the present invention.
