Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a buckle for effectively protecting a rocker arm. Background Art

[0002] For example, the weighing rocker module provided by the publication number CN218115441U-Weighing rocker module and the processing system containing the same discloses that the weighing rocker module includes a rocker mechanism, the rocker mechanism has a containing cavity for containing materials; a shaking mechanism, the shaking end of the shaking mechanism is connected to the rocker mechanism; and a weighing mechanism, the weighing mechanism carries the entire shaking mechanism and can obtain the weight of the shaking mechanism. The weighing rocker module shakes the material contained in the containing cavity of the rocker mechanism by simultaneously setting a shaking mechanism, and setting a weighing mechanism to weigh the material contained in the containing cavity;

[0003] Since the weighing rocker arm module needs to carry out the functions of shaking and weighing at the same time, the connection between the weighing mechanism and the shaking mechanism is relatively precise. When the device moves as a whole, the deadweight of the rocker arm mechanism and the connecting rod mechanism will produce a large feedback to the weighing mechanism, resulting in reduced sensitivity of the weighing mechanism, errors, or even damage. Utility Model Content

[0004] The utility model provides a buckle for effectively protecting a rocker arm, which specifically comprises:

[0005] The main body has two upper and lower parallel horizontal end faces; the main body is provided with a guide plane, there is a height difference between the guide plane and the upper horizontal end face of the main body, and a contact surface is provided between the guide plane and the upper horizontal end face; the contact surface is an arc structure, and the maximum distance between the contact surface and the upper horizontal end face is less than the minimum distance between the guide plane and the upper horizontal end face.

[0006] Optionally, the included angle a between the guide plane and the upper horizontal end surface is 0-45°.

[0007] Optionally, an adjustment hole is opened inside the main body, and an adjustment seam is provided at one end of the adjustment hole close to the guide plane.

[0008] Optionally, a Velcro strap is fixedly connected to the surface of the main body.

[0009] Optionally, it also includes a weighing rocker arm module with a rocking end; the cross-sectional shape of the rocking end of the weighing rocker arm module is consistent with the contact surface.

[0010] Beneficial Effects

[0011] In the utility model, the contact surface is recessed to a certain extent compared with the guide plane, and the curvature of the contact surface is the same as that of the shaking end, so that after the shaking end matches the contact surface, there is a certain height of misalignment with the guide plane. Through the above structure, the force point of the shaking end / weighing rocker arm module is transferred from the weighing mechanism to the installation table, thereby reducing the damage to the weighing mechanism caused by the deadweight of the shaking mechanism, etc. when the device moves.

[0023] In order to make the purpose, scheme and advantages of the technical solution of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the specific embodiments of the utility model.

[0024] Example: Please refer to Figures 1 to 4 :

[0025] The utility model proposes a buckle for effectively protecting a rocker arm, comprising: a main body 1, having two upper and lower parallel horizontal end faces; the main body 1 is provided with a guide plane 104, a height difference between the guide plane 104 and the upper horizontal end face of the main body 1, and a contact surface 103 is provided between the guide plane 104 and the upper horizontal end face; the main body 1 is made of metal as a whole, and its lower end face is flush with and in contact with the mounting table of the weighing rocker arm module. When the main body 1 is installed between the mounting table and the rocking end of the weighing rocker arm module, the guide plane 104 first supports the rocking end until the rocking end is in contact with the contact surface 103. 03 matches; the contact surface 103 is an arc-shaped structure, and the maximum distance between the contact surface 103 and the upper horizontal end surface is smaller than the minimum distance between the guide plane 104 and the upper horizontal end surface; the contact surface 103 is somewhat recessed compared with the guide plane 104, and at the same time, the curvature of the contact surface 103 is the same as that of the shaking end, so that after the shaking end matches the contact surface 103, it has a certain height of misalignment with the guide plane 104. Through the above structure, the force point of the shaking end / weighing rocker arm module is transferred from the weighing mechanism to the installation table, thereby reducing the damage to the weighing mechanism caused by the deadweight of the shaking mechanism, etc. when the device moves.

[0026] Among them, Figure 1 As shown, the angle a between the guide plane 104 and the upper horizontal end surface is 0-45°; the angle between the guide plane 104 and the upper horizontal end surface causes the height of the main body 1 inserted into the lower side of the rocking end to gradually increase during the insertion process. At the same time, during the insertion process, the guide plane 104 can always maintain a tangent state with the rocking end, and the assembly process is smoother.

[0027] Among them, Figure 1 , Figure 2 and Figure 3 As shown, an adjustment hole 101 is opened inside the main body 1, and an adjustment seam 102 is provided at one end of the adjustment hole 101 close to the guide plane 104; the main body 1 is divided into two upper and lower areas by the adjustment hole 101 and the adjustment seam 102. When the guide plane 104 is inserted along the lower side of the rocking end, the rocking end will squeeze the guide plane 104. The adjustment hole 101 and the adjustment seam 102 allow the upper area of ​​the main body 1 to have a certain deformation ability. While maintaining the support of the contact surface 103 for the rocking end, the contact between the rocking end and the main body 1 is buffered to avoid damage caused by excessive force on the rocking end.

[0028] Among them, Figure 1 and Figure 2 As shown, a Velcro 2 is fixedly connected to the surface of the main body 1; the buckle is stored by the Velcro 2 to avoid loss of the buckle.

[0029] Among them, Figure 4 As shown, it also includes a weighing rocker arm module 3 with a rocking end; the cross-sectional shape of the rocking end of the weighing rocker arm module 3 is consistent with the contact surface 103.

[0030] Specific usage and function of this embodiment: In the utility model, the main body 1 is made of metal as a whole, and its lower end face is flush with and in contact with the mounting table of the weighing rocker arm module. When the main body 1 is installed between the mounting table and the rocking end of the weighing rocker arm module, the guide plane 104 first supports the rocking end until the rocking end matches the contact surface 103.

[0031] The above description is merely an exemplary embodiment of the present invention and is not intended to limit the protection scope of the present invention. The protection scope of the present invention is determined by the appended claims.
