Technical Field

[0001] The utility model relates to the technical field of depth measurement, in particular to a device for measuring the depth of a longitudinal narrow space. Background Art

[0002] Longitudinal narrow spaces refer to those with limited vertical height. These spaces are often narrow and difficult to observe and measure. However, in order to utilize these spaces, the spatial dimensions must be measured first. Only based on the measured dimensional data can subsequent adaptive design be carried out. Currently, the depth of longitudinal narrow spaces is generally measured using laser instruments or tape measures. However, some narrow spaces are small and located in locations that are not easily measured with laser equipment, so only tape measures can be used. For narrow spaces with long lengths and varying internal depths, measuring with tape measures can result in large errors, which significantly affects the accuracy of subsequent designs. Therefore, a solution is urgently needed.

[0024] Example

[0025] See also Figure 1-6 As shown:

[0026] The utility model provides a device for measuring the depth of a longitudinal narrow space, comprising a measuring ruler 20 and a connection adjustment component.

[0027] In a specific application, the measuring ruler 20 is used to measure the depth of a narrow longitudinal space. One end of the measuring ruler 20 is configured as a measuring end 21, which is configured in a spike shape. The spike of the measuring end 21 abuts against the inner wall A of the narrow longitudinal space. The spike shape enables accurate detection of the deepest depth when the inner wall A is uneven.

[0028] The measuring ruler 20 is engraved with scale marks 22 along its length for easy reading by an operator. The connecting and adjusting assembly is sleeved on the measuring ruler 20 and is used to connect adjacent measuring rulers 20.

[0029] Through the connection components, multiple measuring rulers 20 can be used simultaneously in one measurement. By arranging the measuring rulers 20 side by side along the connection adjustment group, a comprehensive measurement of the longitudinal narrow space can be performed. After the measurement, the distribution of the deepest unevenness inside the longitudinal narrow space can be discovered, thereby measuring more comprehensive depth data of the longitudinal narrow space.

[0030] The connection adjustment assembly mainly consists of a single-hole connection block 10, a multi-hole connection block 30 and a connection piece.

[0031] A nesting hole 13 is provided in the center of the single-hole connecting block 10. A measuring ruler 20 nests with the nesting hole 13. A series hole 31 is provided in the center of the multi-hole connecting block 30. The series hole 31 nests with at least three measuring rulers 20. Connectors are provided on both sides of the single-hole connecting block 10. Multi-hole connecting blocks 30 connect to adjacent multi-hole connecting blocks 30 or single-hole connecting blocks 10.

[0032] In specific applications, the operator connects multiple single-hole connecting blocks 10 or multi-hole connecting blocks 30 in series according to the depth distribution area to be measured in the longitudinal narrow space, then inserts the measuring ruler 20 into the set hole 13 or the series hole 31, and then inserts it into the longitudinal narrow space, and adjusts each measuring ruler 20 so that the spikes of the measuring end 21 of each measuring ruler 20 are in contact with the inner wall A of the longitudinal narrow space, so that the depth of different positions inside the longitudinal narrow space can be comprehensively measured, thereby improving the accuracy of the depth measurement data.

[0033] The connector includes a dovetail tenon 11 and a dovetail slot 12. The dovetail tenon 11 is located on one side of a single-hole connecting block 10; the dovetail slot 12 is located on the other side of the single-hole connecting block 10. The dovetail slot 12 forms a tenon-and-groove fit with the dovetail tenon 11 on the adjacent single-hole connecting block 10. The dovetail tenon 11 and dovetail slot 12 are located on either side of the multi-hole connecting block 30.

[0034] In actual use, by plugging the dovetail tenons 11 and dovetail grooves 12 on adjacent single-hole connecting blocks 10 or multi-hole connecting blocks 30, adjacent single-hole connecting blocks 10 or multi-hole connecting blocks 30 can be quickly connected in series, thereby improving measurement efficiency.

[0035] It also includes a measuring rod; the other end of the measuring ruler 20 is set as a connecting end; and the connecting end of the measuring rod and measuring ruler 20 constitutes a detachable connection, generally set as a threaded connection.

[0036] When the depth of the longitudinal narrow space to be measured is deeper, since the measuring rod is provided with scale lines along the length direction, the scale lines on the measuring rod and the data of the scale marks 22 on the measuring ruler 20 are arranged in sequence. By connecting the measuring ruler 20 to the measuring rod, it is only necessary to read the value of the scale lines on the measuring rod to know the depth of the longitudinal narrow space, thereby improving the convenience of the measuring ruler 20 in measuring the depth of the longitudinal narrow space.

[0037] It should be noted that if the embodiments of the present invention involve directional indications such as up, down, left, right, front, back, etc., then such directional indications are only used to explain the relative positional relationship and movement of the various components in a specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indications will also change accordingly. In addition, if the embodiments of the present invention involve descriptions such as "first" and "second", then such descriptions such as "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features specified as "first" and "second" can explicitly or implicitly include at least one of such features. In addition, the meaning of "and / or" appearing throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions where both A and B are satisfied. In addition, "multiple" refers to more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist.
