DETAILED DESCRIPTION

[0050] In order to make the purpose, technical scheme and advantages of the present application more clear, the technical scheme of the present application will be described clearly and completely below by combining the specific embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0051] A tape measure tape includes a tape body; a reference measurement mark and a first measurement scale mark are arranged on the front and / or back of the tape body; the first measurement scale mark is symmetrically or asymmetrically arranged on both sides of the reference measurement mark. The tape measure tape is a measuring component of a tape measure. In use, the reference measurement mark can be adjusted to the infrared coincidence position of the level at the reference position. After adjusting the tape measure to a new to-be-measured position, the height difference between the to-be-measured position and the reference measured position can be known through the height comparison between the reference measurement mark and the infrared of the level, and the intuitiveness of measurement is improved. At the same time, through reading the first measurement scale mark, the construction personnel can accurately read the height difference value between the to-be-measured position and the reference position, and know that the to-be-measured position is higher or lower than the reference position by comparison with the reference measurement mark, thereby effectively avoiding value misreading. Embodiment 1

[0052] As shown in Figure 1 and Figure 2 , the tape measure tape includes a tape body 201, and a reference measurement mark 202 and a first measurement scale mark are arranged on the back of the tape body 201. The reference measurement mark 202 is not arranged at the end of the tape body 201, but has a certain distance from the end of the tape body 201, and the first measurement scale mark is symmetrically arranged on both sides of the reference measurement mark 202.

[0053] Specifically, the first measurement scale mark is a first scale line 203 and a first scale value 204, the first scale value 204 is arranged along the measurement direction of the tape body 201, and the first scale value 204 above the reference measurement mark 202 and the first scale value 204 below the reference measurement mark 202 are sequentially increased to both sides with the reference measurement mark 202 as the starting point.

[0054] It should be noted that the first scale value 204 above the reference measurement mark 202 and the first scale value 204 below the reference measurement mark 202 are sequentially decreased to both sides with the reference measurement mark 202 as the starting point. This arrangement can also solve the corresponding technical problems and achieve intuitive reading of the measurement result. In addition, the first measurement scale mark can be in imperial or metric units.

[0055] Similarly, the first measurement scale mark can also be asymmetrically arranged on both sides of the reference measurement mark 202, for example: the number of the first scale line 203 and the first scale value 204 above the reference measurement mark 202 is more than that below the reference measurement mark 202, or the number of the first scale line 203 and the first scale value 204 below the reference measurement mark 202 is more than that above the reference measurement mark 202. This arrangement can only affect the range of the tape measure tape, but has little effect on the intuitiveness of measurement and the measurement result.

[0056] It should be noted that, in this embodiment, the front side of the ruler 201 is the side of the ruler that is in a wound state inside the measuring tape, close to the center, which is the side of an ordinary measuring tape with scale lines and scale values. The back side of the ruler 201 is the opposite side of the front side of the ruler 201.

[0057] Furthermore, in this embodiment, the value of the first scale value 204 increases sequentially to both sides starting from the reference measurement mark 202, and the first scale value 204 above the reference measurement mark 202 has a negative sign to distinguish it from the scale value 204 below the reference measurement mark 202. By setting positive and negative values ​​above and below the reference measurement mark 202, data misreading by construction personnel during operation can be further avoided.

[0058] Furthermore, in another embodiment of this utility model, the first scale value 204 below the reference measurement mark 202 is a negative number, and the scale value 204 above the reference measurement mark 202 is a positive number. This setting can also satisfy the present solution and solve the corresponding technical problems.

[0059] Meanwhile, in this embodiment, a second measurement scale mark is provided on the front side of the ruler 201. The second set of scale marks also includes measurement scale marks, which are the second scale line 211 and the second scale value 212, but it does not have a reference measurement mark 202. The second scale value 212 in the second set of scale marks increases sequentially from the end of the ruler 201.

[0060] The design of setting measurement scale markings on both the back and front of the ruler body 201 can increase the adaptability of the measuring tape and expand its application range.

[0061] Preferably, the reference measurement mark 202 is a zero mark and / or a zero mark value. It should be noted that, to facilitate reading the reference measurement mark 202, it can be set to a more conspicuous color, or the font size can be enlarged. Similarly, the reference measurement mark 202 can be set to a more conspicuous color and its font size can be enlarged simultaneously. Example 2

[0062] Example 2 is the same as Example 1. The only difference is:

[0063] like Figure 2 As shown, on the back of the ruler 201, the first scale value 204 above the reference measurement mark 202 is a positive number, and the first scale value 204 below the reference measurement mark 202 is also a positive number. This setting can also realize the data reading of the position to be measured.

[0064] It should be noted that when the first scale value 204 above the reference measurement mark 202 is positive, the first scale value 204 below the reference measurement mark 202 can be either positive or negative. Conversely, when the first scale value 204 above the reference measurement mark 202 is negative, the first scale value 204 below the reference measurement mark 202 can be either positive or negative. All of the above settings can meet the data reading requirements of construction personnel for the measurement location. Example 3

[0065] Example 3 is the same as Example 1. The only difference is:

[0066] like Figure 4 As shown, on the back of the ruler 201, the text for the first scale value 204 is positioned perpendicular to the measurement direction of the ruler 201. Simultaneously, the first scale value 204 above the reference measurement mark 202 is positive, while the first scale value 204 below the reference measurement mark 202 is negative. The use of positive and negative values ​​on both sides of the reference measurement mark 202 effectively prevents construction personnel from misreading the measurement data. Example 4

[0067] Example 4 is the same as Example 1. The only difference is:

[0068] like Figure 5 As shown, two sets of scale markings are provided on the front of the ruler body 201. The first set of scale markings includes a reference measurement mark 202 and measurement scale markings provided above and below the reference measurement mark 202. The measurement scale markings are a first scale line 203 and a first scale value 204.

[0069] The first set of scale markings is used in conjunction with the infrared light of the level to obtain the levelness data of the position to be measured.

[0070] The second set of scale markings also includes measurement scale markings, namely the second scale line 211 and the second scale value 212, but it does not have a reference measurement marking 202. The second scale value 212 in the second set of scale markings increases sequentially from the end of the ruler body 201.

[0071] Setting measurement scale markings on the same side of the ruler body 201 can increase the adaptability of the measuring tape and expand its application range.

[0072] It should be noted that, in another embodiment of this utility model, two sets of scale markings are provided on the back of the ruler body 201. The first set of scale markings includes a reference measurement mark 202 and measurement scale markings provided above and below the reference measurement mark 202. The measurement scale markings are a first scale line 203 and a first scale value 204.

[0073] Similarly, in another embodiment of the utility model, on the front and back of the ruler body 201, two groups of scale marks are arranged, wherein the first group of scale marks comprises a reference measurement mark 202 and measurement scale marks arranged above and below the reference measurement mark 202, and the measurement scale marks are first scale lines 203 and first scale values 204. This arrangement enables corresponding reading and measurement on the front and back of the ruler body 201, improving the universality of the tape measure. Embodiment 5

[0074] Based on the same inventive concept, the tape measure with a correction function in embodiment 5 comprises any one of the tape measure tapes in embodiments 1-6.

[0075] As shown in the figure, the tape measure with a correction function comprises a tape measure tape 200, a tape measure shell 400 and a brake button 600 for locking the tape measure tape 200. Figures 6-9

[0076] The side of the tape measure shell 400 is provided with a tape inlet and outlet 410; the tape end of the tape measure tape 200 extends outside the tape measure shell 400 through the tape inlet and outlet 410, and the inside of the tape measure shell 400 has a containing cavity for containing the tape measure tape 200. The tail part of the tape measure tape 200 and the part connected with the tail part are wound in the containing cavity. The brake button acts on the region of the tape measure tape 200 between the tape end and the part wound in the containing cavity. In addition, the tape measure further comprises a floor sitting device arranged perpendicularly to the extended part of the tape measure tape 200.

[0077] The brake button 600 comprises a brake tongue capable of moving to the side of the tape measure tape 200 and tightly adhering to the inner wall of the tape measure shell 400. By relying on the compression and friction of the brake tongue on the side of the tape measure tape 200, the tape measure tape 200 can be locked.

[0078] In addition, the containing cavity inside the tape measure shell 400 is provided with a tape reel 700 for coiling the tape measure tape 200. The tape measure tape 200 is partially coiled on the tape reel 700.

[0079] In this embodiment, the floor sitting device is a base body 500 fixedly connected with the tape measure shell 400; the base body 500 comprises a base plane perpendicular to the extended part of the tape measure tape 200. Under the action of the floor sitting device, the tape measure can be stably placed on the ground, preventing the influence on the measurement result caused by the movement or dumping of the tape measure.

[0080] Preferably, the cross-sectional width of the base body 500 is greater than the maximum cross-sectional width of the tape measure shell 400, and the larger bottom surface can further improve the stability of the tape measure.

[0081] ​As another embodiment of the utility model, a tape measure with correction function further comprises a locking device 100 for locking the tape measure tape 200. The locking device 100 is fixedly connected with the tape measure shell 400.

[0082] Specifically, the locking device 100 comprises an assembly shell 101, a first pressing block 109 and a second pressing block 110. The assembly shell 101 is provided with a mounting cavity, and the first pressing block 109 and the second pressing block 110 are arranged in the mounting cavity. The first pressing block 109 and the second pressing block 110 have a gap through which the tape measure tape 200 can pass; the locking device 100 is configured to lock the tape measure tape 200 between the first pressing block 109 and the second pressing block 110 by adjusting the position of the first pressing block 109 and / or the second pressing block 110.

[0083] It should be noted that the scheme that the first pressing block 109 and the second pressing block 110 are partially arranged in the mounting cavity and the remaining part is located outside the mounting cavity is also applicable to the present application.

[0084] In the embodiment, the first pressing block 109 is at least partially arranged in the mounting cavity, and the first locking screw 102 is threadedly connected with the first pressing block 109 through the side wall of the assembly shell 101. The second pressing block 110 is fixedly connected with the assembly shell 101.

[0085] As another embodiment of the utility model, the locking device 100 further comprises a reinforcing plate 112 fixedly connected with the side wall of the assembly shell 101. The reinforcing plate 112 is arranged between the inner wall of the assembly shell 101 and the first pressing block 109. The first locking screw 102 penetrates through the side wall of the assembly shell 101 and the reinforcing plate 112 and is rotationally connected with the side wall of the assembly shell 101 and the reinforcing plate 112 in the circumferential direction thereof; the position of the first locking screw 102 in the axial direction thereof is limited by the side wall of the assembly shell 101 and the reinforcing plate 112. The reinforcing plate 112 can increase the strength and prevent the side wall of the assembly shell 101 from being damaged, and at the same time, the reinforcing plate 112 has sufficient rigidity and can support the first locking screw 102 and the first pressing block 109.

[0086] At the same time, in order to facilitate the processing of the tape measure, the assembly shell 101 can adopt a two-half structure along the center of symmetry, and the arrangement of the reinforcing plate 112 can effectively overcome the poor rigidity and strength caused by the first locking screw 102 being located at the joint of the two halves of the assembly shell 101.

[0087] As another embodiment of the utility model, the locking device 100 further comprises a fixing block 113 for fixing the reinforcing plate 112, and the fixing block 113 is fixedly connected with the inner wall of the assembly shell 101. In addition, the fixing block 113 comprises an upper half and a lower half, and the first pressing block 109 is slidingly arranged between the upper half and the lower half of the fixing block 113, so that the fixing block 113 can limit the first pressing block 109, and thus the first pressing block 109 can slide perpendicularly to the measuring tape 200 at the position to be locked.

[0088] As another embodiment of the utility model, the locking device 100 further comprises an anti-skid gasket 111, which is attached to the surface of the first pressing block 109 and / or the second pressing block 110 on the side in contact with the measuring tape 200.

[0089] That is, the anti-skid gasket 111 can be attached only to the surface of the first pressing block 109 on the side close to the second pressing block 110, or the anti-skid gasket 111 can be attached only to the surface of the second pressing block 110 on the side close to the first pressing block 109. In addition, the anti-skid gasket 111 can be attached to the surface of the first pressing block 109 on the side close to the second pressing block 110 and to the surface of the second pressing block 110 on the side close to the first pressing block 109. The arrangement of the anti-skid gasket 111 can increase the friction between the first pressing block 109 and / or the second pressing block 110 and the measuring tape 200, further increasing the locking effect of the locking device 100 on the measuring tape 200. At the same time, the anti-skid gasket 111 can also effectively protect the reference measurement mark 202 and the first and second measurement scale marks of the measuring tape 200.

[0090] During construction and interior decoration, the base body 500 can be placed on the ground to stably place the tape measure, and the tape body 201 can be extended to a set length, so that the reference measurement mark 202 and the corresponding measurement scale mark are extended to a set position, ensuring that the extended tape body 201 is perpendicular to the ground to be measured. The intersection position of the infrared ray of the level and the measuring tape 200 is observed, and the height of the measuring tape 200 is adjusted so that the reference measurement mark 202 coincides with the position of the infrared ray of the level. The measuring tape 200 is locked by the brake button 600 and / or the locking device 100. When measuring other points to be measured, the measuring tape 200 is locked in place, the tape measure is placed at the position to be measured, and the distance between the reference measurement mark 202 and the infrared ray is read and recorded, so as to realize the data of the position to be measured. Due to the arrangement of the reference measurement mark 202, the data reading of the position to be measured is more convenient, the reading efficiency is improved, and the reading error is reduced. Embodiment 6

[0091] Embodiment 6 is the same as embodiment 5, except that:

[0092] As Figures 10-13The locking device 100 also comprises a first locking screw 102 for adjusting the position of the first pressing block 109, the first locking screw 102 penetrates through the side wall of the assembly shell 101 and is rotationally connected with the side wall of the assembly shell 101 in the circumferential direction; the position of the first locking screw 102 in the axial direction is limited, so that the first locking screw 102 can rotate in the fixed position under the action of external force, and the position of the first locking screw 102 does not change along the axial direction. The first locking screw 102 is threadedly connected with the first pressing block 109 arranged in the mounting cavity, and the first pressing block 109 can move along the axis of the first locking screw 102 by the thread connection.

[0093] In the embodiment, in order to ensure that the first pressing block 109 can move, the side wall of the assembly shell 101 is provided with a first adjusting slot hole 103. The first adjusting slot hole 103 is symmetrically arranged on both sides of the assembly shell 101; the first sliding shaft 104 penetrates the first adjusting slot hole 103 and is fixedly connected with the first pressing block 109.

[0094] That is, in this scheme, by the fixing action of the first sliding shaft 104 and by the arrangement of the first adjusting slot hole 103, the first pressing block 109 can slide along the length direction of the first adjusting slot hole 103, and by the thread connection between the first locking screw 102 and the first pressing block 109, the first pressing block 109 can move, and then by the extrusion action of the second pressing block 110, the locking of the tape 200 is realized. In this case, the second pressing block 110 can adopt a fixed structure or a movable structure.

[0095] It should be noted that the length direction of the first adjusting slot hole 103 is arranged in the same direction as the axial direction of the first locking screw 102, so as to ensure the effective movement of the first pressing block 109.
