Description

Technical Field

[0001] The utility model relates to the field of electronic vehicle scales, in particular to a portable electronic scale. Background Art

[0002] Portable electronic scales, also known as portable automobile axle weighing instruments, portable electronic floor scales, portable automobile weighing instruments, portable axle weight detectors, portable over-limit detectors, etc., are mainly used in automobile manufacturing and automobile testing. By allowing the automobile to dynamically pass or remain stationary on a weighing table of a certain width, the weighing table weighs the weight of each wheel, and then accumulates the axle weight and the total weight of the automobile, and then judges the stability of the automobile design and other functions according to certain standards;

[0003] The working principle of the weighing platform of a portable electronic scale is as follows: when the car tire applies heavy pressure to the weighing platform, the weighing platform sensor will release a voltage signal. The output signal size is proportional to the weight of the tire. The signal is transmitted to the amplifier for amplification, and then converted into a digital signal through an analog-to-digital converter and displayed on the monitor. The value obtained by a single plate is the wheel weight of the car, and the two plates are the axle weight. According to the axle type of the car, the total weight of the car can be accumulated.

[0004] Compared with traditional electronic scales, portable electronic scales are light in weight, easy to carry and flexible in use. One side of the weighing platform is equipped with rollers and the other side is equipped with a handle, which can be easily pushed and pulled. However, in actual use, since there are only two flush rollers, it can only be pulled at an angle. In this way, the weight of the portable electronic scale will act on the handle during the transfer process, and this weight will also cause fatigue to the operator's arms. In order to further reduce the gravity exerted by the portable electronic scale on the operator's arms during the transfer process, a portable electronic scale is provided. Utility Model Content

[0026] 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.

[0027] See also Figures 1 to 3 In an embodiment of the utility model, a portable electronic scale includes a portable electronic scale 1 composed of a weighing platform 101 and a ramp block 102. The ramp block 102 is rotatably connected to the two ends of the weighing platform 101 through a hinge. The same end of the weighing platform 101 and the ramp block 102 is respectively installed with a first universal wheel 2 and a second universal wheel 3. Two first universal wheels 2 are symmetrically installed on the weighing platform 101, and two ramp blocks 102 are each installed with a second universal wheel 3. The other end of the weighing platform 101 is fixedly connected with a handle 4. When the weighing platform 101 and the ramp block 102 are in an upright and overlapping state, the two first universal wheels 2 and the two second universal wheels 3 can enable the weighing platform 101 and the ramp block 102 to remain in an upright state without external support, thereby realizing easy transfer of the weighing platform 101 and the ramp block 102.

[0028] The weighing platform 101, the handle 4 and the ramp block 102 are provided with fixing components 5, and the fixing components 5 are used to fix the ramp block 102 in a folded state;

[0029] The fixing assembly 5 includes a locking unit and a storage unit. The locking unit is used to fix the ramp block 102 in a folded state. The storage unit is used to store the locking column 503 in the locking unit when the portable electronic scale 1 is placed flat on the ground.

[0030] The locking unit includes a limiting slide groove 501, a U-shaped block 502, a locking column 503, and a positioning hole 504;

[0031] The limiting slide groove 501 is symmetrically opened at the top of the handle 4 and penetrates to the bottom of the limiting slide groove 501. The two vertical parts of the U-shaped block 502 penetrate the limiting slide groove 501 and are fixedly connected to the locking column 503. The locking column 503 is located at one end of the U-shaped block 502 close to the weighing platform 101.

[0032] The positioning hole 504 is formed at one end of the outer wall of the ramp block 102. When the ramp block 102 is folded, the locking column 503 is inserted into the positioning hole 504 to fix the ramp block 102 in the folded state.

[0033] A return spring 506 is disposed inside the limiting slide groove 501, one end of the return spring 506 is bonded and fixed to the inner wall of the limiting slide groove 501, and the other end of the return spring 506 is in contact with the end surface of the vertical portion of the U-shaped block 502;

[0034] The limiting slide groove 501 provides space for the horizontal movement of the U-shaped block 502 and is used to realize the insertion or separation of the locking column 503 and the positioning hole 504. The reset spring 506 is used to provide reset power for the moving limiting slide groove 501.

[0035] In this embodiment: when the portable electronic scale 1 is not in daily use, the slope block 102 is folded and attached to the bottom of the weighing platform 101 (it should be noted that the bottom surface refers to the side of the weighing platform 101 that is attached to the ground when the weighing platform 101 is on the platform). At this time, the locking column 503 is clamped in the positioning hole 504 to keep the slope block 102 in a stable folded state. When transferring the portable electronic scale 1 in this state, two methods can be used, which are as follows:

[0036] The first method is to make the first universal wheel 2 and the second universal wheel 3 all contact the ground, at which time the portable electronic scale 1 is kept in an upright state as a whole, and then it can be moved by horizontal pushing;

[0037] The second method is to make the second universal wheel 3 contact the ground and the first universal wheel 2 away from the ground. At this time, the portable electronic scale 1 is tilted as a whole, and the portable electronic scale 1 is pulled by pulling the handle 4;

[0038] The two moving modes make the transfer of the portable electronic scale 1 more flexible. In addition, the first universal wheel 2 and the second universal wheel 3 are all in contact with the ground, which makes it easier to move compared to the moving mode in which a single wheel contacts the ground.

[0039] When the ramp block 102 needs to be unfolded, it is only necessary to pull the U-shaped block 502 when the portable electronic scale 1 is in an upright state, so that the U-shaped block 502 moves along the limiting slide groove 501 and squeezes the reset spring 506 to contract. The U-shaped block 502 drives the locking column 503 to move out of the positioning hole 504. At this time, the ramp block 102 can be rotated to open, and then it can be placed flat on the ground as a whole to use the portable electronic scale 1.

[0040] Please refer to Figures 1 to 3 , the storage unit includes a storage groove 505;

[0041] The storage groove 505 is provided at the bottom of the weighing platform 101 and extends to one end of the outside of the weighing platform 101. The storage groove 505 and the locking column 503 are aligned in the vertical direction. When the weighing platform 101 is placed flat on the ground, the locking column 503 is stored in the storage groove 505.

[0042] One end of the return spring 506 close to the U-shaped block 502 is in contact with the U-shaped block 502 but not connected thereto. When the U-shaped block 502 is located at the initial position, the return spring 506 is in an uncompressed state.

[0043] In this embodiment: the return spring 506 can make the U-shaped block 502 not easy to slide in the initial position. When the U-shaped block 502 moves along the limiting slide groove 501, the return spring 506 is squeezed and contracted. After the U-shaped block 502 is released, the return spring 506 can return the U-shaped block 502 to the initial position.

[0044] When the portable electronic scale 1 is placed flat on the ground, the locking column 503 will be squeezed by the ground and moved upward and contracted into the receiving groove 505, so that it will not affect the horizontality of the weighing platform 101. During this process, the return spring 506 will remain stationary.

[0045] Please refer to Figures 1 to 3 When the two ramp blocks 102 are in a folded state, the two second universal wheels 3 are distributed on both sides of the two first universal wheels 2 .

[0046] In this embodiment, the second universal wheel 3 and the first universal wheel 2 will not affect the folding operation of the ramp block 102 through this structure.

[0047] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
