Description

Technical Field

[0001] The utility model relates to the technical field of floor scales, in particular to a floor scale device with a buffer component. Background Art

[0002] A floor scale, also known as a car scale or truck scale, is a device used to measure the weight of cars or trucks and their loads. This device is often used in industries such as industry, agriculture, and mining that require a large amount of items to be moved and the weight of these items to be measured. A buffer mechanism is required when using it.

[0003] For example, the floor scale device with a buffer assembly with patent announcement number CN 220982428 U includes a fixed frame, a first mounting groove is provided inside the fixed frame, and a plurality of card slots are provided at the top of the inner wall of the fixed frame; a first buffer mechanism is installed at the bottom of the first mounting groove, a floor scale body is installed on the top of the first buffer mechanism, a second buffer mechanism is installed at the bottom of the floor scale body, and a card block is fixedly connected to the outer wall of the floor scale body. The utility model is designed with a first buffer mechanism and a second buffer mechanism, and the floor scale device buffers the floor scale body through two buffer mechanisms, thereby greatly improving the buffering effect of the floor scale, thereby reducing the damage of the impact force to the floor scale body, and further improving the use effect of the floor scale body.

[0004] However, in actual use of the above-mentioned equipment, the buffer mechanism cannot be linked when local force is applied to the scale, resulting in the scale still being easily tilted when subjected to force, and the buffering effect is poor, which urgently needs to be improved. Utility Model Content

[0005] The purpose of the utility model is to provide a floor scale device with a buffer assembly to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a floor scale device with a buffer assembly, including a buffer frame and a floor scale body, first buffer components are fixedly installed at positions around the bottom of the buffer frame, the first buffer components include a fixed tube, a sliding tube and a spring component, the tops of the four sliding tubes are fixedly connected to the bottom of the floor scale body, linkage rods are fixedly installed between adjacent sliding tubes, a cross rod is arranged between the linkage rods at both ends of the buffer frame, and a plurality of second buffer components equidistantly distributed are fixedly installed on the tops of the cross rods.

[0007] The top of the inner wall of the buffer frame is provided with an installation groove, a first rubber sheet is fixedly installed around the installation groove, and a second rubber sheet is fixedly installed around the floor scale body.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The floor scale device with a buffer assembly, when in use, uses the first buffer to buffer the force on the four sides of the floor scale body. The setting of the linkage rod can distribute the force transmission, reduce the bearing force of a single buffer, and prevent the corners of the floor scale body from curling up. The second buffer on the cross rod then evenly buffers the center position of the floor scale body, thereby improving the buffering strength of the floor scale body.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The usual way to use a scale is that a car or truck drives onto the platform of the scale, and then the scale measures its weight. Since the scale itself is subject to a large force, a buffer component is required to cushion and unload the force. The buffer component is usually placed at the bottom or side of the scale to cushion the force exerted on the scale, avoid damage to the scale body, reduce the loss of the scale, and extend the service life of the scale.

[0021] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a floor scale device with a buffer assembly, including a buffer frame 1 and a floor scale body 2, first buffer members 3 are fixedly installed at positions around the bottom of the buffer frame 1, the first buffer member 3 includes a fixed tube 301, a sliding tube 302 and a spring member 303, the tops of four sliding tubes 302 are fixedly connected to the bottom of the floor scale body 2, and linkage rods 4 are fixedly installed between adjacent sliding tubes 302, a cross rod 5 is arranged between the linkage rods 4 at both ends of the buffer frame 1, and a plurality of second buffer members 6 equidistantly distributed are fixedly installed on the top of the cross rod 5.

[0022] The first buffer member 3 is used to buffer the force on all sides of the floor scale body 2. The linkage rod 4 is arranged to distribute the force transmission, reduce the bearing force of a single buffer member, and prevent the corners of the floor scale body 2 from warping. The second buffer member 6 on the cross rod 5 then buffers the center position of the floor scale body 2 evenly, thereby improving the buffering strength of the floor scale body 2.

[0023] A mounting groove is provided at the top of the inner wall of the buffer frame 1 , and a first rubber sheet 7 is fixedly installed around the mounting groove, and a second rubber sheet 8 is fixedly installed around the scale body 2 .

[0024] The combination of the first rubber sheet 7 and the second rubber sheet 8 can provide a sealing effect between the buffer frame 1 and the scale body 2, while improving the buffering effect of the scale body 2 through the fitting characteristics between the rubber sheets.

[0025] like Figure 3 As shown, the first rubber sheet 7 is arranged to be inclined outward, and the second rubber sheet 8 is arranged to be inclined inward.

[0026] The shape of the first rubber sheet 7 and the second rubber sheet 8 is equivalent to adding a circle of rubber buffer belt to the floor scale body 2, so as to further improve the buffer strength of the device.

[0027] A plurality of grooves 10 equidistantly distributed are formed on the inclined surface of the first rubber sheet 7 , and convex strips 9 matching the grooves 10 are formed on the inclined surface of the second rubber sheet 8 .

[0028] The combination of the convex strip 9 and the concave groove 10 can increase the sinking resistance of the second rubber sheet 8, thereby improving the buffering strength of the device on the scale body 2.

[0029] A deformation cavity 11 is defined inside the first rubber sheet 7 .

[0030] The provision of the deformation cavity 11 can prevent the first rubber sheet 7 from breaking when being squeezed, thereby improving the stability of the device.

[0031] An exhaust hole 12 communicating with the deformation cavity 11 is provided at the center of the bottom of the inclined surface of the first rubber sheet 7 .

[0032] The provision of the exhaust hole 12 can also prevent the first rubber sheet 7 from being deformed too much, which would cause the air pressure inside the deformation cavity 11 to be too high and cause the first rubber sheet 7 to rupture, thereby improving the stability of the device during buffering operations.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
