DETAILED DESCRIPTION

[0020] 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.

[0021] like Figure 1 As shown;

[0022] A pit-free floor scale comprises a base 1 and a weighing scale body 2 installed at the center of the top of the base 1 . Slope protection mechanisms 3 are arranged on the top of the base 1 at two ends of the weighing scale body 2 .

[0023] In this embodiment: Under normal circumstances, the position of the scale will shift after long-term use, but the scale is mostly installed by bolts, which makes it very inconvenient to disassemble. In addition, due to the load of the truck, the scale without a pit is raised above the ground, which requires the truck to be weighed on a slope before weighing, so the service life of the slope is reduced after being compressed for a long time. In addition, the slope protection mechanism 3 is added to avoid the problem that due to the load of the truck, the scale without a pit is raised above the ground, which requires the truck to be weighed on a slope before weighing, so the service life of the slope is reduced after being compressed for a long time.

[0024] like Figure 1 - Figure 7 As shown;

[0025] Based on the existing foundation pit scale, by adding the slope protection mechanism 3 and the side wall protection mechanism 4, it is possible to solve the problem in the prior art that the position of the scale will shift after long-term use. Since the installation of the scale is mostly fixed by bolts, it is very inconvenient to disassemble. Moreover, due to the load of the truck, the scale without a foundation pit is raised above the ground, which requires the truck to go up the slope before weighing, so the service life of the slope is reduced after being under pressure for a long time.

[0026] More specifically:

[0027] In combination with the above content, in order to effectively solve the problem of reduced service life of the slope, a slope protection mechanism 3 is arranged at the top of the base 1 relative to the two ends of the weighing scale body 2. The slope protection mechanism 3 includes a slope seat 31, a buffer spring 32, a clamping groove 33, a mounting hole 34 and a movable clamping assembly 35. The two ends of the weighing scale body 2 are provided with mounting grooves 11 relative to the top of the base 1, one end of the buffer spring 32 is evenly installed on the inner bottom of the mounting groove 11, the bottom of the slope seat 31 is fixedly connected to the other end of the buffer spring 32, a mounting hole 34 is opened on one side of the mounting hole 34, one end of the movable clamping assembly 35 is installed in the mounting hole 34, the clamping groove 33 is opened at the bottom of one side of the slope seat 31, and the other end of the movable clamping assembly 35 is clamped with the clamping groove 33.

[0028] In this embodiment: when the truck needs to be weighed, since mounting grooves 11 are provided at both ends of the weighing scale body 2 relative to the top of the base 1, one end of the buffer spring 32 is evenly installed on the inner bottom of the mounting groove 11, and the bottom of the ramp seat 31 is fixedly connected to the other end of the buffer spring 32, and then when the truck passes through the ramp seat 31, under the action of the buffer spring 32, the protectiveness of the ramp seat 31 is improved to a certain extent, and since a mounting hole 34 is provided on one side of the mounting hole 34, one end of the movable clamping assembly 35 is installed in the mounting hole 34, and the clamping groove 33 is provided at the bottom of one side of the ramp seat 31, and the other end of the movable clamping assembly 35 is clamped with the clamping groove 33, and then through the action of the movable clamping assembly 35, the ramp seat 31 can maintain a stable connection with the weighing scale body 2 after being pressed down.

[0029] It should be noted that the movable snap-in assembly 35 includes a snap-in ball 351, a first snap-in plate 352 and a second snap-in plate 353. The snap-in ball 351 is rotatably snap-into the mounting hole 34. One side of the first snap-in plate 352 is fixedly connected to one side of the snap-in ball 351. One side of the second snap-in plate 353 is fixedly connected to the other side of the first snap-in plate 352. Both the first snap-in plate 352 and the second snap-in plate 353 are snap-into the snap-in groove 33.

[0030] In this embodiment: because the locking ball 351 is rotated and locked in the mounting hole 34, one side of the first locking plate 352 is fixedly connected to one side of the locking ball 351, and one side of the second locking plate 353 is fixedly connected to the other side of the first locking plate 352, and then by locking the first locking plate 352 and the second locking plate 353 in the locking groove 33, and then under the action of the locking ball 351, after the ramp seat 31 is pressed down, the locking ball 351 synchronously rotates downward by the same angle, so that the ramp seat 31 can maintain a stable connection with the weighing scale body 2.

[0031] It should be understood that the top of the slope seat 31 and the side adjacent to the weighing scale body 2 are both arc edges, and a connecting rod is provided between the clamping ball 351 and the first clamping plate 352, and they are connected through the connecting rod.

[0032] Furthermore, it also includes a side wall protection mechanism 4 arranged on both sides of the base 1, and the side wall protection mechanism 4 includes a limit base 41, a mounting plate 42, a limit bolt 43, a limit block 44, a threaded sleeve 45 and a limit spring 46. The limit base 41 is symmetrically installed on both sides of the base 1, one side of the mounting plate 42 is symmetrically fixedly connected to the two sides of the base 1, and limit grooves 411 are evenly spaced on both sides of the interior of the limit base 41.

[0033] In this embodiment: because the weight of a truck is usually very large, and there is no foundation pit scale protruding from the ground, it is easy to deviate after long-term use. Therefore, the limiting base 41 is symmetrically installed on both sides of the base 1, and one side of the mounting plate 42 is symmetrically fixedly connected to both sides of the base 1. First, the limiting base 41 is pre-buried in the ground. At the same time, the limiting grooves 411 are evenly spaced on both sides of the inner side of the limiting base 41. One end of the limiting spring 46 is fixedly connected to the inner side of the limiting groove 411, and one end of the limiting block 44 is fixedly connected to the other end of the limiting spring 46. Fixed connection, one end of the threaded sleeve 45 is fixedly connected to the top of the limit block 44, one end of the limit bolt 43 is threadedly penetrated through the top of the mounting plate 42 and is threadedly connected to the other end of the threaded sleeve 45, and then under the action of the limit bolt 43, the base 1 can be installed on the top of the limit base 41 under the action of the mounting plate 42, and under the action of the limit spring 46, when the truck is weighed, under the action of the limit spring 46, the limit block 44 can elastically slide left and right in the limit groove 411, thereby reducing the problem of base 1 offset.

[0034] The above disclosure is only a specific embodiment of the present invention, but the embodiments of the present invention are not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
