Technical Field

[0001] The utility model relates to the technical field of tape measure verification, in particular to a tape measure verification device. Background Art

[0002] A tape measure is a commonly used tool in daily life. A steel tape measure is often used in construction and decoration and is also one of the essential tools for families. In addition, tape measures also include fiber tape measures, etc. After the production of the tape measure, a verification device is required to complete the verification work of the scale line of the tape measure. It has the advantages of simple operation, stable structure, and accurate verification in actual use.

[0003] The prior art discloses a steel tape measure verification platform machine with the publication number of CN219607873U. In the above utility model, only one tape measure can be verified at a time. For the verification work of multiple tape measures, the verification needs to be carried out sequentially. This verification method has low work efficiency. At the same time, there is no cleaning structure, and the impurities on the surface of the tape measure cannot be scraped off. When the pressing structure presses the tape measure, the adsorbed impurities are likely to press and damage the tape measure, reducing the practicality of this utility model.

[0004] Therefore, we propose a tape measure verification device to solve the above drawbacks. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the disadvantages existing in the prior art, and to provide a tape measure verification device that can verify multiple tape measures simultaneously and can scrape off the impurities on the surface of the tape measure.

[0006] In order to achieve the purpose of being able to verify multiple tape measures simultaneously and being able to scrape off the impurities on the surface of the tape measure, the utility model adopts the following technical scheme: A tape measure verification device includes a concave frame. The front and rear end faces of the concave frame are both penetrated by mounting blocks. A winding roller is penetrated between the two groups of mounting blocks through bearings. A concave plate is installed on the rear end face of the concave frame, and a reduction motor is installed on the rear end face of the concave plate. The output end of the reduction motor is connected to the winding roller through a coupling. An installation frame and an installation screw are installed inside the concave frame. Multiple installation nuts and multiple clamping plates are sleeved on the side wall of the installation screw. A control panel is installed on the end face of the concave frame. Multiple moving rings are slidably sleeved on the side wall of the winding roller. Multiple fastening bolts are spirally penetrated through the outer walls of the multiple moving rings.

[0007] Preferably, scale marks are provided on the side wall of the winding roller.

[0008] Preferably, the installation screw and the multiple installation nuts are in threaded cooperation with each other.

[0009] Preferably, a bidirectional lead screw is installed inside the installation frame through bearings, and two lead screw sleeves are sleeved on the side wall of the bidirectional lead screw. Socket plates are fixedly sleeved on the side walls of the two lead screw sleeves. A vertical rod slides through between the two socket plates, and the two ends of the vertical rod are respectively fixedly connected to the inner top surface and the bottom surface of the installation frame. Installation through grooves are formed in the upper parts of the two socket plates. Connecting screws are installed inside the two installation through grooves, and connecting blocks and two sets of connecting nuts are sleeved on the side walls of the two connecting screws. Four sponge plates are adhesively bonded to the surfaces of the two connecting blocks. A forward and reverse motor is installed on the upper part of the installation frame, and the output end of the forward and reverse motor is connected to the bidirectional lead screw. The forward and reverse motor is electrically connected to the control panel through an electric wire.

[0010] Preferably, the bidirectional lead screw and the two lead screw sleeves are in threaded cooperation with each other.

[0011] Preferably, the two connecting screws and the four connecting nuts are in threaded cooperation with each other.

[0012] Preferably, the control panel is electrically connected to the reduction motor through an electric wire.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows;

[0014] (1). The present utility model adopts a winding roller. When actually using the tape measure verification device, the operator places multiple tape measures between multiple clamping plates by hand, and then moves the multiple clamping plates. When the multiple clamping plates respectively contact the multiple tape measures, by using the threaded cooperation between the installation screws and the multiple installation nuts, the operator rotates the multiple installation nuts clockwise and counterclockwise by hand. When the multiple installation nuts are respectively in close contact with the multiple clamping plates, the use positions of the multiple clamping plates and the multiple tape measures are fixed. Then the operator moves the end parts of the tapes of the multiple tape measures between the multiple moving rings respectively. When the multiple moving rings clamp the end parts of the tapes of the multiple tape measures, the operator rotates the fastening bolts clockwise by hand. When the multiple fastening bolts are in close contact with the winding roller, the use positions of the multiple moving rings are fixed. Then, by using the control panel, the reduction motor is made to work. The output end of the reduction motor can wind the end parts of the multiple tape measures through the winding roller. The scale markings on the side wall of the winding roller can verify the scale lines of the end parts of the multiple tape measures. By providing the winding roller, multiple tape measures can be verified simultaneously, improving the verification efficiency of the tape measure verification device.

[0015] (2) The present utility model adopts an installation frame. According to the above operations, it can be known that the end parts of the measuring tapes need to be moved between multiple moving rings. Before that, the end parts of the multiple measuring tapes need to pass through the gaps between two sets of socket plates, and then the forward and reverse motor is made to work by using the control panel. The output end of the forward and reverse motor can drive the bidirectional lead screw to rotate. Since the bidirectional lead screw is in threaded cooperation with the two sets of lead screw sleeves, the rotating bidirectional lead screw can push the two sets of lead screw sleeves closer to or farther away from each other. The two sets of lead screw sleeves drive two sets of connecting blocks to move respectively through the two sets of socket plates. When the two sponge plates contact the measuring tape parts of the multiple measuring tapes, as the measuring tape parts of the multiple measuring tapes are wound up, the two sponge plates can wipe the surfaces of the measuring tape parts of the multiple measuring tapes. When the sponge plates need to be replaced, by using the threaded cooperation between two sets of connecting screws and four sets of connecting nuts, the operator rotates the four sets of connecting nuts counterclockwise by hand. When the four sets of connecting nuts are separated from the two sets of connecting blocks, the two sets of connecting blocks are rotated by 90 degrees, and then the four sets of connecting nuts are rotated clockwise. When the four sets of connecting nuts are in close contact with the four sets of connecting blocks respectively, the replacement and use of the sponge plates are completed. Through the provided installation frame, impurities on the surface of the measuring tape can be scraped off, improving the practicality of the measuring tape calibration device.

[0040] Working principle:

[0041] When actually using the tape measure verification device, the operator places multiple tape measures between multiple groups of clamping plates 9 by hand, and then moves multiple groups of clamping plates 9. When multiple groups of clamping plates 9 respectively contact multiple tape measures, by using the threaded cooperation between the mounting screw 7 and multiple groups of mounting nuts 8, the operator rotates multiple groups of mounting nuts 8 clockwise and counterclockwise by hand. When multiple groups of mounting nuts 8 respectively come into close contact with multiple groups of clamping plates 9, the usage positions of multiple groups of clamping plates 9 and multiple tape measures are fixed. Then the operator moves the scale ends of multiple tape measures between multiple moving rings 11 respectively. When multiple groups of moving rings 11 clamp the scale ends of multiple tape measures, the operator rotates the fastening bolts 12 clockwise by hand. When multiple groups of fastening bolts 12 come into close contact with the winding roller 3, the usage positions of multiple groups of moving rings 11 are fixed. Then, by using the control panel, the reduction motor 5 is made to work. The output end of the reduction motor 5 can wind the scale parts of multiple tape measures through the winding roller 3. The scale markings on the side wall of the winding roller 3 can verify the scale lines of the scale parts of multiple tape measures. By providing the winding roller 3, multiple tape measures can be verified simultaneously, improving the verification efficiency of the tape measure verification device. At the same time, according to the above operations, the scale ends of multiple tape measures need to be moved between multiple moving rings 11. Before that, the scale ends of multiple tape measures need to pass through the gap between two sets of socket plates 15, and then by using the control panel, the forward and reverse motor 10 is made to work. The output end of the forward and reverse motor 10 can drive the bidirectional lead screw 13 to rotate. Since the bidirectional lead screw 13 is in threaded cooperation with two sets of lead screw sleeves 14, the rotating bidirectional lead screw 13 can push two sets of lead screw sleeves 14 to move closer to or away from each other. Two sets of lead screw sleeves 14 respectively drive two sets of connecting blocks 19 to move through two sets of socket plates 15. When two sets of sponge plates 21 contact the scale parts of multiple tape measures, as the scale parts of multiple tape measures are wound, two sets of sponge plates 21 can wipe the surfaces of the scale parts of multiple tape measures. When the sponge plates 21 need to be replaced, by using the threaded cooperation between two sets of connecting screws 18 and four sets of connecting nuts 20, the operator rotates four sets of connecting nuts 20 counterclockwise by hand. When four sets of connecting nuts 20 are separated from two sets of connecting blocks 19, two sets of connecting blocks 19 are rotated by 90 degrees, and then four sets of connecting nuts 20 are rotated clockwise. When four sets of connecting nuts 20 respectively come into close contact with four sets of connecting blocks 19, the replacement and use of the sponge plates 21 are completed. By providing the mounting frame 6, impurities on the surface of the tape measure can be scraped off, improving the practicality of the tape measure verification device.
