[0001] This utility model relates to the field of measuring tool technology, and in particular to a multifunctional measuring ruler. Background Technology

[0002] In numerous industries such as machinery manufacturing, construction, electronic component processing, and parts testing, length measurement is a fundamental step throughout the entire production and construction process, directly affecting product accuracy and project quality. Traditional rulers, with their simple structure, low cost, intuitive operation, and portability, have become widely used tools in daily measurement. Whether it's checking the dimensions of routine workpieces or quickly measuring distances on construction sites, their ease of use meets basic measurement needs.

[0003] Whether in industrial or household measurement scenarios, the length of a traditional ruler is usually fixed. When faced with scenarios where the length to be measured varies greatly, staff need to purchase multiple rulers with different lengths and measurement ranges. When it is necessary to accurately measure the clamping outer diameter of an object, calipers also need to be purchased, which is costly and inconvenient to use. Utility Model Content

[0004] The purpose of this utility model is to provide a multifunctional measuring ruler to solve the above-mentioned technical problems. It can be applied to various measurement scenarios corresponding to conventional rulers, calipers and extended rulers. It is highly functional, easy to use, widely applicable, cost-saving and improves measurement efficiency.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A multifunctional measuring ruler, comprising:

[0007] A first measuring ruler and a second measuring ruler, wherein the second measuring ruler has a fitting groove along its length, and the first measuring ruler is slidably disposed in the fitting groove. The first measuring ruler and the second measuring ruler are respectively provided with a first scale group and a second scale group along their length. The first measuring ruler has a widened end outside the starting point of the first scale group. The first end of the second measuring ruler and the widened end form the clamping end of the multifunctional measuring ruler. The first end of the second measuring ruler is the end near the starting point of the second scale group.

[0008] The aforementioned multifunctional measuring ruler, wherein the first measuring ruler includes a ruler portion and a widened end portion, the width of the widened end portion matching the width of the second measuring ruler, and the length of the fitting groove matching the length of the ruler portion.

[0009] The aforementioned multifunctional measuring ruler includes an upper clamping end and a lower clamping end. The fitting groove is opened from the middle of the second measuring ruler and is located above the second scale group. The ruler part is connected to the middle of the widened end. The upper clamping end and the lower clamping end are respectively formed on the upper and lower sides of the ruler part and the upper and lower sides of the fitting groove in the head end.

[0010] In the aforementioned multifunctional measuring ruler, the first measuring ruler and the second measuring ruler are detachable and separable from each other. When the first measuring ruler slides in the fitting groove, the first scale group and the second scale group are arranged in parallel.

[0011] In the aforementioned multifunctional measuring ruler, the widened end is detachably connected to the ruler portion, and the widened end and the ruler portion can be locked together by a locking member.

[0012] In the aforementioned multifunctional measuring ruler, one of the ruler portion and the fitting groove is provided with a sliding block, and the other is provided with a sliding groove. The sliding block can slide and connect to the sliding groove along the length direction of the second measuring ruler.

[0013] In the aforementioned multifunctional measuring ruler, the sliding blocks are respectively provided at both ends of the ruler portion in the width direction, and the sliding blocks extend along the length direction of the ruler portion. Sliding grooves are respectively provided on the two opposite groove walls of the fitting groove, and the sliding grooves extend along the length direction of the second measuring ruler.

[0014] The aforementioned multifunctional measuring ruler further includes a limiting component configured to restrict the sliding of the first measuring ruler relative to the second measuring ruler and to unlock the sliding restriction of the first measuring ruler relative to the second measuring ruler.

[0015] The aforementioned multifunctional measuring ruler also includes a limiting rope, one end of which is connected to the end of the first measuring ruler near the end of the first scale group, and the other end of which is connected to the bottom of the fitting groove. The bottom of the fitting groove is also provided with a receiving groove for accommodating the limiting rope, so that when the first measuring ruler slides to the bottom of the fitting groove, the limiting rope is stored in the receiving groove.

[0016] In the aforementioned multifunctional measuring ruler, the length of the limiting rope does not exceed the length of the ruler section; when the ruler section slides to the point where the limiting rope is taut, the end line of the first scale group is located at the starting line of the second scale group.

[0017] The beneficial effects of this utility model are:

[0018] The multifunctional measuring ruler provided by this utility model allows for convenient and efficient measurement of objects with irregular shapes. For irregularly shaped objects, the second measuring ruler can be pulled to clamp the object between its tip and the widened end of the first measuring ruler, enabling direct reading of the first scale group's value. For regularly shaped and short objects, the second measuring ruler can be slid so that its tip is close to the widened end, reducing space occupation and allowing direct reading of the second scale group's value. For regularly shaped and long objects, the second measuring ruler can be pulled away from the widened end, superimposing the readings of the second and first scale groups to expand the measuring range. The sum of the second and first scale group readings gives the object's size.

[0019] In other words, when the widened end of the first measuring ruler is in contact with the head end of the second measuring ruler, the external shape of the measuring ruler is no different from that of a regular ruler. When the first or second measuring ruler is pulled, it can be used as a caliper or an extended ruler. In this way, a measuring ruler can be used in a variety of measurement scenarios, including regular rulers, calipers, and extended rulers. It is highly functional, easy to use, widely applicable, cost-effective, and improves measurement efficiency. Attached Figure Description

[0032] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] In the description of this utility model, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1-8As shown, the multi-functional measuring ruler includes a first measuring ruler 1 and a second measuring ruler 2. The second measuring ruler 2 has a fitting groove 21 along its length direction. The first measuring ruler 1 is slidably disposed in the fitting groove 21. The first measuring ruler 1 and the second measuring ruler 2 are respectively provided with a first scale group 121 and a second scale group 22 along their length directions. The first measuring ruler 1 has a widened end 11 outside the starting point of the first scale group 121. The first end of the second measuring ruler 2 and the widened end 11 form the clamping end of the multi-functional measuring ruler. The first end of the second measuring ruler 2 is the end close to the starting point of the second scale group 22.

[0037] The multifunctional measuring ruler provided by this utility model allows for convenient and efficient measurement of objects with irregular shapes. For objects with irregular shapes, the second measuring ruler 2 can be pulled to clamp the object between its head and the widened end 11 of the first measuring ruler 1, enabling direct reading of the reading from the first scale group 121. For objects with regular shapes and short lengths, the second measuring ruler 2 can be slid so that its head is close to the widened end 11, reducing space occupation and allowing direct reading of the reading from the second scale group 22. For objects with regular shapes and long lengths, the second measuring ruler 2 can be pulled away from the widened end 11, causing the reading from the second scale group 22 to be superimposed on the reading from the first scale group 121, thus expanding the measuring range. The size of the object is obtained by adding the reading from the second scale group 22 to the reading from the first scale group 121.

[0038] In other words, when the widened end 11 of the first measuring ruler 1 is in contact with the head end of the second measuring ruler 2, the external shape of the measuring ruler is no different from that of a regular ruler. When the first measuring ruler 1 or the second measuring ruler 2 is pulled, it can be used as a caliper or an extended ruler. In this way, a measuring ruler can be used in a variety of measurement scenarios, including regular rulers, calipers and extended rulers. It is highly functional, easy to use, widely applicable, cost-effective, and improves measurement efficiency.

[0039] It should be noted that the fitting groove 21 can be either a groove or a hole, as long as the first measuring ruler 1 can slide within the fitting groove 21. When the fitting groove 21 is a groove, the first scale group 121 on the first measuring ruler 1 is directly exposed, making it easy to read; when the fitting groove 21 is a hole, the second measuring ruler 2 is made of transparent material, making it easy to read the reading of the first scale group 121.

[0040] The outer surfaces of the first measuring ruler 1 and the second measuring ruler 2 have a smooth transition, which can avoid scratching the measuring personnel and improve safety.

[0041] In this embodiment, see Figures 1 to 3The first measuring ruler 1 includes a ruler portion 12 and a widened end portion 11. The width of the widened end portion 11 matches the width of the second measuring ruler 2. The length of the fitting groove 21 matches the length of the ruler portion 12, and the width of the widened end portion 11 matches the width of the second measuring ruler 2. This ensures that when the tip of the second measuring ruler 2 is close to the widened end portion 11, the overall external shape of the measuring ruler is no different from a conventional ruler, without any protruding edges, thus avoiding scratches to the measuring personnel. If the length of the ruler portion 12 is greater than the length of the fitting groove 21, at least a portion of the ruler portion 12 will be located outside the fitting groove 21, increasing the minimum length of the multi-functional measuring ruler. If the length of the ruler portion 12 is less than the length of the fitting groove 21, the ruler portion 12 cannot contact the bottom of the fitting groove 21, further increasing the minimum length of the multi-functional measuring ruler. Therefore, matching the length of the fitting groove 21 with the length of the ruler portion 12 ensures that the ruler portion 12 is completely fitted into the fitting groove 21, improving space utilization and reducing the space occupied by the multi-functional measuring ruler.

[0042] Specifically, the widened end 11 and the ruler 12 are detachably connected. The widened end 11 and the ruler 12 can be locked together by the locking member 13. The detachable connection between the widened end 11 and the ruler 12 allows for the replacement of rulers 12 with different ranges or different accuracies, thus improving the practicality of the multi-functional measuring ruler.

[0043] Further, see Figures 3 to 5 The ruler part 12 has a mounting groove 123, and the widened end 11 can be clamped in the mounting groove 123. The surface of the ruler part 12 and the widened end 11 are flush, which reduces space occupation, reduces surface protrusion, and avoids scratching the staff.

[0044] Specifically, see Figure 3 , Figure 5 , Figure 6 and Figure 8 The locking member 13 is a countersunk bolt. The widened end 11 has a first fixing hole 111, and the ruler part 12 has a second fixing hole 124. The first fixing hole 111 is a threaded hole, and the second fixing hole 124 is a countersunk hole. The locking member 13 passes through the second fixing hole 124 and is screwed into the first fixing hole 111. The head of the locking member 13 is embedded in the second fixing hole 124 to reduce surface protrusion, avoid scratching the measuring personnel, and reduce safety hazards.

[0045] The clamping end is used to clamp the object to be measured; for details, see [link to documentation]. Figures 1 to 3The clamping end includes an upper clamping end and a lower clamping end. A fitting groove 21 is formed from the middle of the second measuring ruler 2 and located above the second scale group 22. The ruler part 12 is connected to the middle of the widened end 11. The upper and lower clamping ends are formed on the upper and lower sides of the ruler part 12 in the widened end 11 and on the upper and lower sides of the fitting groove 21 in the first end, respectively. During use, both the upper and lower clamping ends can clamp the object to be measured, improving measurement efficiency. Furthermore, even if the upper clamping end is damaged, the lower clamping end can still perform the clamping and measurement function, extending the service life of the multi-functional measuring ruler.

[0046] In this embodiment, the first measuring ruler 1 and the second measuring ruler 2 are detachable and separable from each other. When the first measuring ruler 1 slides in the fitting groove 21, the first scale group 121 and the second scale group 22 are arranged in parallel. The detachable and separable nature of the first measuring ruler 1 and the second measuring ruler 2 allows for separate measurement of regular objects with short lengths, improving measurement efficiency. The parallel arrangement of the first scale group 121 and the second scale group 22 ensures that the measurement references of the first measuring ruler 1 and the second measuring ruler 2 are the same, further improving measurement efficiency.

[0047] In this embodiment, one of the ruler portion 12 and the fitting groove 21 is provided with a sliding block 122, and the other is provided with a sliding groove 23. The sliding block 122 can slide and connect to the sliding groove 23 along the length direction of the second measuring ruler 2. The sliding groove 23 provides a guiding function for the sliding block 122, thereby improving the stability of the ruler portion 12 sliding in the fitting groove 21.

[0048] Further, see Figures 3 to 7 Sliding blocks 122 are provided at both ends of the ruler 12 in the width direction. The sliding blocks 122 extend along the length direction of the ruler 12. Sliding grooves 23 are provided on the two opposite groove walls of the fitting groove 21. The sliding grooves 23 extend along the length direction of the second measuring ruler 2, further improving the stability of the ruler 12 sliding in the fitting groove 21.

[0049] To further improve the measurement effect, in this embodiment, the multifunctional measuring ruler also includes a limiting component. The limiting component is configured to restrict the sliding of the first measuring ruler 1 relative to the second measuring ruler 2 and to unlock the sliding restriction of the first measuring ruler 1 relative to the second measuring ruler 2, thus restricting the second measuring ruler 2 to the limiting position. When measuring a long object, it is only necessary to read the reading of the second scale group 22 on the second measuring ruler 2 and the reading of the first scale group 121 at the limiting position. It is not necessary to read the reading of the first scale group 121 for each measurement, which simplifies the measurement steps and improves the measurement efficiency.

[0050] Optionally, the limiting assembly includes a limiting spring and a limiting steel ball. A limiting groove is formed on the sliding block 122, and a limiting spring is installed in the limiting groove. The two ends of the limiting spring are respectively fixedly connected to the limiting steel ball and the bottom of the limiting groove. When the second measuring ruler 2 is installed, the second measuring ruler 2 pushes the limiting steel ball into the limiting groove, and the second measuring ruler 2 can slide to a position that fits against the first measuring ruler 1.

[0051] To ensure that the limiting steel ball can limit the second measuring scale 2 to the limiting position, a limiting protrusion is provided at the end of the groove wall of the fitting groove 21 near the widened end 11. The limiting protrusion can push the limiting steel ball to compress the limiting spring into the limiting groove. After the limiting protrusion slides away with the second measuring scale 2, there is a gap between the limiting steel ball and the groove wall of the fitting groove 21. Under the action of the limiting spring, the limiting steel ball pops out and abuts against the groove wall of the fitting groove 21. When the second measuring scale 2 is in the limiting position, the limiting steel ball can abut against the end of the limiting protrusion away from the widened end 11, thereby limiting the second measuring scale 2.

[0052] Optionally, the multifunctional measuring ruler also includes a limiting rope 3. One end of the limiting rope 3 is connected to the end of the first measuring ruler 1 near the end of the first scale group 121, and the other end of the limiting rope 3 is connected to the bottom of the fitting groove 21. The bottom of the fitting groove 21 is also provided with a receiving groove for accommodating the limiting rope 3, so that when the first measuring ruler 1 slides to the bottom of the fitting groove 21, the limiting rope 3 is stored in the receiving groove. The limiting rope 3 being stored in the receiving groove can reduce space occupation and improve space utilization. The limiting rope 3 is taut to limit the second measuring ruler 2 to the limiting position. When measuring a long object, it is only necessary to read the reading of the second scale group 22 on the second measuring ruler 2 and the reading of the first scale group 121 at the limiting position, which improves the measurement efficiency.

[0053] Specifically, the length of the limiting rope 3 does not exceed the length of the ruler 12; when the ruler 12 slides to the point where the limiting rope 3 is taut, the end line of the first scale group 121 is located at the starting line of the second scale group 22, so that the range of the multi-functional measuring ruler is the range of the first measuring ruler 1 plus the range of the second measuring ruler 2, eliminating the need to carry a large-range measuring tool and improving the practicality of the multi-functional measuring ruler.

[0054] Specifically, one end of the limiting rope 3 is attached to the first measuring ruler 1, and the other end of the limiting rope 3 is attached to the bottom of the receiving groove. The attachment is convenient, can achieve non-damaging fixation, and can be adapted to narrow spaces without occupying extra space, thus improving space utilization.

[0055] The multifunctional measuring ruler provided by this utility model allows for the following measurement methods: When in use, the second measuring ruler 2 can be pushed so that its first end is tightly against the widened end 11, and the reading can be taken using the second scale group 22 of the second measuring ruler 2. This enables the measurement of objects with regular shapes. Pulling the second measuring ruler 2 to the limit position increases the measurement range, allowing for the measurement of longer objects. For objects with irregular shapes, the first end of the second measuring ruler 2 and the widened end 11 of the first measuring ruler 1 can clamp the object, and the reading of the first scale group 121 can be taken.

[0056] When the widened end 11 of the first measuring ruler 1 is in contact with the head end of the second measuring ruler 2, the overall external shape of the measuring ruler is no different from that of a regular ruler. When the first measuring ruler 1 or the second measuring ruler 2 is pulled, it can be used as a caliper or an extended ruler. In this way, a measuring ruler can be used in a variety of measurement scenarios, including regular rulers, calipers and extended rulers. It is highly functional, easy to use, widely applicable, cost-effective, and improves measurement efficiency.

[0057] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
