Abstract
Description
Technical Field
[0001] This utility model relates to the field of core measurement technology, and in particular to a telescopic fixed-division calculation ruler. Background Technology
[0002] In geological work such as coalfield exploration, underground exploration, delamination grouting, and core analysis, core analysis is frequently conducted. Cores are retrieved from underground and placed in core boxes for geologists to analyze, determining the core's properties, strata, thickness, depth, and other relevant data. However, when the coring drill pipe is drilling underground, the core is subjected to pressure from the core tube, affecting its length. Core boxes also vary in length, making the core length inaccurate. Furthermore, cores are lost during retrieval, and human factors further influence their placement in the core box, causing deviations between the placed core length and the actual drilled length. This creates difficulties for geological analysts, making it hard to accurately determine the depth of a given core layer. Often, they can only estimate the depth manually, greatly hindering the process of determining strata depth. Unavoidable errors in determining the depth of rock strata are also present. Utility Model Content
[0003] In view of this, the purpose of this utility model is to propose a telescopic constant division slide rule to solve some or all of the technical problems in the background art.
[0004] To achieve the above objectives, this utility model provides a telescopic fixed-division slide rule, comprising: a main support rod, a connecting rod group, and a secondary support rod connected in sequence;
[0005] The connecting rod group includes multiple sets of interlocking cross rods. The outermost set of cross rods is slidably mounted on the main support rod by a limiting member, and the other outermost set of cross rods is slidably mounted on the secondary support rod by a sliding member. The cross distance of the multiple sets of cross rods changes as the secondary support rod moves.
[0006] Optionally, each set of crossbars includes two crossbars, which are hinged in the middle. Each crossbar has a through hole at its end. Adjacent sets of crossbars are connected by a fixing member in the through hole. The ends of the two outermost crossbars are rotatably mounted on the corresponding limiting member, and the ends of the two outermost crossbars are rotatably mounted on the corresponding sliding member.
[0007] Optionally, the limiting member is sleeved on the main support rod, and the side wall of the limiting member is provided with bolt holes, and a fixing bolt is provided in the bolt holes. When the fixing bolt is tightened, the fixing bolt abuts against the support rod.
[0008] Optionally, the limiting member is nail-shaped, and the limiting member has a slot, the size of which corresponds to the size of the main support rod, and the main support rod passes through the slot.
[0009] Optionally, the main support rod is provided with a sliding groove, and a protrusion is provided in the groove, the protrusion being located within the sliding groove.
[0010] Optionally, the fastener is I-shaped, and a sleeve is fitted onto the fastener, the sleeve passing through a through hole at the end of the cross bar.
[0011] Optionally, the slider is nail-shaped and has a through hole, through which the secondary support rod passes.
[0012] Optionally, the secondary support rod is provided with external threads, and two sets of adjustment components that cooperate with the sliding member are provided on the secondary support rod. Each set of adjustment components includes two nuts, and the two nuts are respectively located at the upper and lower ends of the corresponding sliding member.
[0013] Optionally, the main support rod has graduations on its side wall.
[0014] As described above, the telescopic fixed-division slide rule provided by this utility model includes a main support rod, a connecting rod group, and a secondary support rod connected in sequence. The connecting rod group comprises multiple sets of interlocking cross rods. The outermost set of cross rods is slidably mounted on the main support rod via a limiting member, and the other outermost set is slidably mounted on the secondary support rod via a sliding member. Movement of the secondary support rod changes the intersecting distance between the multiple sets of cross rods. The main and secondary support rods connect these interlocking cross rods to form a telescopic ruler. When measurement is required, one of the main or secondary support rods can be kept stationary while the other is stretched, causing the interlocking cross rods to stretch and change the intersecting distance. This change in intersecting distance allows for the calculation of the measurement distance, resulting in more accurate measurements of core sample length. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0023] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.
[0024] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.
[0025] like Figures 1 to 4 As shown, this utility model provides a telescopic fixed-division slide rule, comprising: a main support rod 1, a connecting rod group 3, and a secondary support rod 2 connected in sequence;
[0026] The connecting rod group 3 includes multiple sets of interlocking cross rods. The outermost set of cross rods is slidably mounted on the main support rod 1 via a limiting member 4, and the other outermost set of cross rods is slidably mounted on the secondary support rod 2 via a sliding member 6. The cross distance of the multiple sets of cross rods changes as the secondary support rod 2 moves.
[0027] Specifically, the main support rod 1 and the secondary support rod 2 connect multiple sets of intersecting cross rods to form a telescopic ruler. When measurement is required, one of the main support rods 1 or the secondary support rod 2 can be kept stationary while the other support rod is stretched, causing the interlocking cross rods to stretch and changing the cross distance between the cross rods. The measurement distance can then be calculated based on the cross distance, making the measurement of core length more accurate.
[0028] The number of crossbars can be set to 6 to 10, but we will set it to 20 for now.
[0029] In some embodiments, such as Figure 1 and Figure 2 As shown, each set of crossbars includes two crossbars, which are hinged in the middle. Each crossbar has a through hole at its end. Adjacent sets of crossbars are connected by a fixing member 33 in the through hole. The ends of the two outermost crossbars are rotatably mounted on the corresponding limiting member 4, and the ends of the two outermost crossbars are rotatably mounted on the corresponding sliding member 6.
[0030] Specifically, each set of crossbars includes two crossbars hinged in the middle. During measurement, pulling one of the support rods changes the distance between the two crossbars. For example, if the height of the crossbar on the main support rod 1 is A, and the length of one crossbar is C, the distance B between the crossbar and the support rod can be calculated using the Pythagorean theorem a^2 + b^2 = c^2. By reading the length of A, and given that C is a fixed length (the distance between the holes at both ends of the crossbar: a constant), the elongation B of the sliding scale (which can be calculated) and the length of each small division can be calculated using the Pythagorean theorem a^2 + b^2 = c^2. The relationship between A and B is A^2 + B^2 = C^2, so 10 × B is the total elongation. This method provides accurate, reliable, flexible, convenient, and intuitive measurement of the core length. It allows for quick division of the total core length into ten equal parts and intuitive determination of the core length within each small division. Accuracy is increased tenfold.
[0031] In some embodiments, such as Figure 1 and Figure 3 As shown, the limiting member 4 is sleeved on the main support rod 1. The limiting member 4 has a bolt hole on its side wall, and a fixing bolt 5 is provided in the bolt hole. When the fixing bolt 5 is locked, the fixing bolt 5 abuts against the support rod.
[0032] Furthermore, such as Figure 3 As shown, the limiting member 4 is nail-shaped, and the limiting member 4 is provided with a slot 41. The size of the slot 41 corresponds to the size of the main support rod 1, and the main support rod 1 is disposed through the slot 41.
[0033] Specifically, the limiting member 4 has a slot 41 corresponding to the main support rod 1, through which the main support rod 1 passes. The limiting member 4 can then move on the main support rod 1. Once it reaches a suitable position, it can be fixed to the main support rod 1 by abutting against the fixing bolt 5. The fixing bolt 5 is located on the limiting member 4 and extends into the slot, thus securing the limiting member 4 to the main support rod 1.
[0034] In some embodiments, such as Figure 1 As shown, the main support rod 1 is provided with a sliding groove, and a protrusion is provided in the groove opening 41, with the protrusion located inside the sliding groove.
[0035] Specifically, a sliding groove is provided on the main support rod 1, and the slot 41 on the limiting member 4 is provided with a corresponding protrusion, which can make the limiting member 4 slide stably up and down on the main support rod 1 and prevent the limiting member 4 from rotating.
[0036] In some embodiments, such as Figure 1 and Figure 4 As shown, the fixing member 33 is in the shape of an I-beam, and a sleeve 331 is fitted on the fixing member 33. The sleeve 331 is provided through the through hole at the end of the cross rod.
[0037] Specifically, the fixing member 33 is provided with a sleeve 331, and the cross rods are sleeved on the fixing member 33, that is, sleeved on the sleeve 331, so as to facilitate the hinge connection of each cross rod.
[0038] In some embodiments, such as Figure 1 As shown, the sliding member 6 is nail-shaped and has a through hole, through which the secondary support rod 2 passes.
[0039] Specifically, since the crossbars at the edges can move up and down on the secondary support rod 2 when they are hinged, the sliding member 6 is stator-shaped and has a through hole, which can ensure that the sliding member 6 slides stably on the secondary support rod 2.
[0040] In some embodiments, such as Figure 1 As shown, the secondary support rod 2 is provided with external threads, and two sets of adjustment components are provided on the secondary support rod 2 to cooperate with the sliding member 6. Each set of adjustment components includes two nuts 7, which are located at the upper and lower ends of the corresponding sliding member 6, respectively.
[0041] Specifically, two sets of adjustment components are set on the secondary support rod 2. Each set of adjustment components includes two nuts 7, which are located at the upper and lower ends of the sliding member 6, respectively. These nuts 7 can limit the movement of the sliding member 6. When the sliding member 6 moves to the appropriate position, the two nuts 7 lock the sliding member 6 to prevent it from sliding, thereby enabling accurate calculation of the measurement results.
[0042] In some embodiments, the main support rod 1 has a scale on its side wall.
[0043] Specifically, the movement position of the limiting member 4 on the support rod can be observed, the distance between the two limiting members 4 can be determined according to the scale, and the distance between each set of cross components can be calculated according to the length of the cross rod, thus calculating the length of the entire ruler based on all cross components.
[0044] Specific implementation of this utility model
[0045] When the telescopic ruler is not in use, it is folded. When in use, the main support rod 1 or the secondary support rod 2 needs to be pulled out. For example, when measuring a core box, the telescopic ruler is placed in the core box, and the two support rods are pulled to make the cross rods hinge together, thereby moving the moving part and the sliding part 6 on the two support rods. After moving to the appropriate position, the moving part and the sliding part 6 are fixed. The moving part is fixed by the fixing bolt 5, and the sliding part 6 is fixed by the two nuts 7. Then, the moving part reads the height A of the main support rod 1. C is a fixed length (the distance between the holes at both ends of the cross rod: a constant). According to the Pythagorean theorem a^2 + b^2 = c^2, the length of the extension B of the sliding ruler can be calculated (it can be calculated), as well as the length of each small division. The relationship between A and B is A^2 + B^2 = C^2, so 10 × B is the total extension length. The calculation is accurate, reliable, flexible, convenient, and intuitive for measuring the length of the core. The total length of the core can be quickly divided into ten equal parts. The length of the rock core within each small grid can be intuitively determined. The accuracy is increased tenfold.
[0046] If we assume the total length of the entire core is B mm, then the length of each cell here is 0.1 x B mm.
[0047] For example, suppose we set the total length (0-10) to 1000mm.
[0048] Then 0~1=100mm; 1~2=100mm; 0~2=200mm...... This makes the location of the rock core layers more intuitive, accurate, easy to operate, accurate in estimation, and intuitive in positioning.
[0049] This device is telescopic and can quickly divide any unit length into equal parts, making it flexible and convenient in practical applications.
[0050] Let's assume we define a unit of length as 1 meter. We can stretch a telescopic ruler to that length and read 0.1 meters at each of the ten equal division points. The key function of this device is to quickly and equally divide any unit of length. This design makes 1 meter no longer a fixed length, but rather a conceptual unit of length that we define, which can be divided into ten equal parts. This breaks with our conventional understanding that length is a fixed value, and we habitually define rulers as measuring tools with a fixed length. However, here, we can set different conceptual units of length, and then use this device to equally divide this (hypothetical) virtual unit of length. For example, we can define "1 meter" as a variable unit of length, and then use the device to equally divide this virtual unit of length into ten equal parts. The device is easy to operate, and the readings are intuitive and reliable.
[0051] This device is suitable for various applications such as core length measurement, drilling depth estimation, stratigraphic dating, and lithological transition depth location determination. It has a novel and unique appearance, ingenious design, and is convenient and practical. It can divide any hypothetical virtual unit length into equal parts and is worthy of widespread promotion.
