Description

Technical Field

[0001] This utility model relates to the field of meter counter technology, specifically to a counterweight mechanism for a meter counter. Background Technology

[0002] A meter counter is an electronic device that uses various electronic components to measure length. A roller-type electronic meter counter works by having a roller roll in contact with the object being measured. The distance the object moves is converted into the number of rotations of the roller, and the length of the object is calculated by combining this with the circumference of the roller. The measurement result is then displayed electronically.

[0003] For example, Chinese Patent Publication No. CN2736735Y discloses a roller-type electronic meter counter, which belongs to the category of length measuring instruments. The roller-type electronic meter counter includes a roller, a rotating shaft, a support, and an electronic counting unit. The roller is fixedly mounted on the rotating shaft, which is mounted on the support via a bearing seat and bearing. The electronic counting unit is also mounted on the support. The electronic counting unit includes a display unit, a counting unit, and a rotating shaft rotation sensing mechanism. The signal output terminal of the rotation sensing mechanism is connected to the input terminal of the counting unit, and the output of the counting unit is connected to the display unit. Because the meter counter in this invention uses electronic counting, it retains the advantages of high counting speed and accuracy of electronic meter counters. Furthermore, the only rotating parts of the entire machine are the roller and the rotating shaft, resulting in fewer wear parts and a longer lifespan. In addition, the electronic counting unit and the roller are fixed on the support to form a single unit, making assembly, disassembly, and relocation very convenient, making it ideal for small and medium-sized enterprises.

[0004] However, during the measurement process, slippage can easily occur between the roller and the object being measured in this type of roller electronic meter, which can affect the measurement accuracy.

[0005] Therefore, the applicant has made beneficial designs and found a way to solve the above problems. The technical solution to be introduced below is generated in this context. Utility Model Content

[0008] A counterweight mechanism for a meter counter includes a meter counter body and a counterweight mechanism for increasing the weight of the meter counter body. Rollers are provided on both sides of the meter counter body, and fixing blocks are provided at the four corners of the bottom of the meter counter body. Each fixing block has a fixing hole. The counterweight mechanism includes a mounting plate and a counterweight mounted on the mounting plate. One end of the mounting plate is bent to provide a hook portion. The top and bottom of the hook portion have several oblong holes (first type). Both sides of the middle surface of the mounting plate have several oblong holes (second type). The end of the mounting plate facing away from the hook portion has mounting holes that mate with the fixing holes. The end of the mounting plate facing away from the hook portion has several assembly holes (first type). The surface of the counterweight has several assembly holes (second type) that mate with the assembly holes (first type).

[0009] Preferably, the waist-shaped holes at the top and bottom of the hook portion are symmetrically arranged.

[0010] Preferably, the several waist-shaped holes on both sides of the middle surface of the mounting plate are symmetrically arranged.

[0011] Beneficial effects

[0012] The above-mentioned technical solutions in the counterweight mechanism of the meter counter provided by this utility model embodiment have at least one of the following technical effects:

[0023] To avoid excessive and unnecessary details, well-known structures or functions will not be described in detail in the following embodiments.

[0024] like Figure 1-4 The diagram shown is a structural schematic of a counterweight mechanism for a meter counter according to a preferred embodiment of the present invention.

[0025] Example 1 includes a meter counter body 1 and a counterweight mechanism 2 for increasing the weight of the meter counter body 1. Rollers 3 are provided on both sides of the meter counter body 1, and fixing blocks 4 are provided at the four corners of the bottom of the meter counter body 1. Each fixing block 4 has a fixing hole 5. The counterweight mechanism 2 includes a mounting plate 6 and counterweight blocks 7 mounted on the mounting plate 6. One end of the mounting plate 6 is bent to provide a hook portion 8. The top and bottom of the hook portion 8 have several oblong holes 9 for passing through. When the hook portion 8 is hooked, it is fixed by the cable ties. Several oblong holes 10 are provided on both sides of the middle surface of the mounting plate 6. The second hole 10 is used to pass through cable ties, which are used to fix the power bank to the middle of the mounting plate 6. The power bank charges the meter counter body 1. The mounting plate 6 has a mounting hole 11 on the surface away from the hook part 8, which matches the fixing hole 5. During installation, screws are screwed into the mounting hole 11 and the fixing hole 5 to fix the meter counter body 1 to the mounting plate 6, thereby completing the installation of the counterweight mechanism 2. The mounting plate 6 has a number of first assembly holes 12 on the surface away from the hook part 8. The counterweight block 7 has a number of second assembly holes 13 on the surface, which matches the first assembly holes 12. During installation, screws are screwed into the second assembly holes 13 and the first assembly holes to fix the counterweight block 7. The counterweight mechanism 2 increases the pressure of the roller 3 on the object being measured by the meter counter body 1, thereby increasing the friction between the roller 3 and the object and effectively improving the measurement accuracy of the meter counter body 1. Furthermore, the hook 8 at one end of the mounting plate 6 forms a hook structure, allowing for hook-type installation during use, which is more convenient and faster than the traditional socket-type installation. (According to the pressure formula P = F / S (P is pressure, F is force, S is the contact area), an increase in weight will increase the force F, while the contact area S between the roller 3 and the object remains constant, so the pressure P will increase. According to the friction formula f = μN (f is friction force, μ is the coefficient of friction, N is the normal force), an increase in weight will increase the normal force N, and with the coefficient of friction μ remaining constant, the friction force f will increase.)

[0026] Specifically, the top and bottom of the hook portion 8 have symmetrically arranged waist-shaped holes 9, which allows the cable ties to pass through the two opposite waist-shaped holes 9 at the top and bottom of the hook portion 8.

[0027] Specifically, a number of waist-shaped holes 10 on both sides of the middle surface of the mounting plate 6 are symmetrically arranged. This structure allows the cable ties to pass through the two opposite waist-shaped holes 10 on both sides of the middle surface of the mounting plate 6.

[0028] In the second embodiment, one end of the mounting plate 6 is provided with a sleeve 14, and the other end of the mounting plate 6 is provided with a mounting hole 11 that matches the fixing hole 5. The end of the mounting plate 6 facing away from the sleeve 14 is provided with a plurality of assembly holes 12.

[0029] The counterweight mechanism of the meter counter of this utility model has common mechanical methods in terms of installation, connection or setting. It can be implemented as long as it can achieve its beneficial effect.

[0030] All technologies not described in detail in this utility model are known technologies. Those skilled in the art can easily implement this utility model based on their understanding of this specification, and the contents shown in the accompanying drawings are part of this specification.

[0031] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
