Description

Technical Field

[0001] This utility model relates to the field of engineering measurement technology, and in particular to a multifunctional measuring device capable of measuring length, width, height and angle. Background Technology

[0002] A measuring device is an instrument or system used to determine the value of a physical quantity. It can measure and record physical quantities such as size, shape, mass, temperature, pressure, flow rate, velocity, and concentration of an object through various methods, including mechanical, optical, electronic, chemical, or biological means. The selection of a measuring device depends on factors such as the nature of the physical quantity being measured, accuracy requirements, and the working environment. When selecting a measuring device, its measurement range, accuracy, stability, reliability, and ease of use and maintenance must be considered. In most industrial fields, measuring devices are used to inspect the dimensions and angles of products to ensure product quality and the accuracy of processes.

[0003] Existing measuring devices (such as the multifunctional measuring device disclosed in announcement number CN220750994U) have solved the problems of limited performance of measuring instruments, large space occupation, easy error, and low efficiency when using multiple measuring tools; however, the movable jaw used for limiting in this device is a rotatable structure. When measuring an object, due to the possible differences in the flatness of the object's surface, the movable jaw is easily pushed and rotated by the uneven structure of the object's surface, making it impossible to ensure that the two guard plates are always parallel when measuring length, resulting in poor measurement accuracy. In addition, the above-mentioned device cannot simultaneously measure the height of the object. The height of the object can only be measured by standing the device upright and measuring twice, which is cumbersome, time-consuming and labor-intensive. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a multifunctional measuring device that can easily measure the length, width, height, and angle of an object.

[0005] To achieve the above objectives, the present invention can adopt the following technical solution:

[0006] The multifunctional measuring device of this utility model includes a length measuring unit, and an angle measuring unit and a height measuring unit connected to the length measuring unit;

[0007] The length measuring unit includes a measuring seat, on which a first measuring groove and a first scale mark are horizontally arranged and adapted to each other. A front edge is vertically arranged at the front end of the first measuring groove. A first measuring block is arranged inside the first measuring groove and slides back and forth along its length direction. A rear edge corresponding to the front edge is vertically arranged at the front edge of the top of the first measuring block.

[0008] The angle measuring unit includes a goniometer fixed to the rear edge. A protractor is horizontally extended rearward from the rear edge of the goniometer. An angle alignment ruler that rotates horizontally is hinged at the center point of the protractor via a hinge shaft. An object-mounted stand is connected to the angle alignment ruler via a pair of horizontally forward elastic telescopic members. The length direction of the object-mounted stand is parallel to the length direction of the angle alignment ruler. The object-mounted stand has a measuring state where it extends forward beyond the rear edge and a storage state where it retracts backward into the goniometer.

[0009] The height measuring unit includes a height measuring base vertically fixed to the front end of the length measuring base. The height measuring base has a second measuring groove and a second scale mark that are mutually adapted to each other. The lower end of the second measuring groove is flush with the top surface of the length measuring base. A second measuring block that slides up and down along its height direction is provided in the second measuring groove.

[0010] Furthermore, a first guide rod aligned with the length direction is provided in the first measuring groove. The first guide rod passes horizontally through the center of the first measuring block. A first spring, fitted onto the first guide rod, is provided in the first measuring groove located behind the first measuring block. The first guide rod ensures the stability of the first measuring block as it slides back and forth along the first measuring groove. The first spring, by having its front end abut against the rear end face of the first measuring block and its rear end abut against the rear end wall of the first measuring groove, pushes the sliding first measuring block to automatically spring back and reset. At this time, a positioning bolt, with its lower end abutting against the first guide rod, should be vertically screwed through the top surface of the first measuring block. When the first measuring block is manually pushed to slide into place, the sliding position of the first measuring block can be fixed by tightening the positioning bolt, ensuring that the first measuring block is stably positioned.

[0011] Furthermore, the first measuring groove is a through groove extending vertically. Four sets of wheels extending out of the first measuring groove are provided at the bottom of the first measuring block. The traveling direction of the wheels is consistent with the sliding direction of the first measuring block. The bottom surfaces of the four sets of wheels are flush with the bottom surface of the measuring base. This ensures that the bottom surface of the measuring base can be stably attached to the ground, while making it easier and smoother for the first measuring block to move back and forth along the first measuring groove. Additionally, a pair of auxiliary limiting rods, aligned with the length direction of the first measuring groove, can be erected parallel to each other at the bottom of the measuring base on the left and right sides of the first measuring block. These auxiliary limiting rods extend horizontally from the bottom of the first measuring block outwards through the lower edge of the first measuring groove, further limiting the forward and backward sliding direction of the first measuring block and effectively preventing the first measuring block from rotating along the first guide rod.

[0012] Furthermore, to enable the adhesive stand to have both a measuring state where it extends forward beyond the angle measuring base and a retracted state where it retracts backward into the angle measuring base, two sets of elastic telescopic components are symmetrically arranged on the left and right sides of the hinge shaft. Each set of elastic telescopic components includes a mounting block fixed to the top surface of the angle alignment ruler. A push rod that slides back and forth is horizontally inserted through the mounting block. The front end of the push rod is vertically fixed to the rear side surface of the adhesive stand, and its rear end is provided with a limiting block for locking behind the mounting block. A second spring for pushing the adhesive stand forward is fitted on the push rod located in front of the mounting block. At the same time, a pair of elastic locking components are provided on the angle measuring base to lock the adhesive stand in the retracted state. The elastic locking components include a groove on the top surface of the angle measuring base and a locking protrusion in the groove. A connecting rod that passes vertically downward through the angle measuring base is provided at the bottom of the locking protrusion. A third spring located in the groove is fitted on the connecting rod, and an anti-dislodgement block is provided at the lower end of the connecting rod.

[0013] Furthermore, a second guide rod aligned with the height direction is provided in the second measuring groove. The second guide rod passes vertically through the center of the second measuring block, ensuring the stability of the second measuring block sliding up and down along the second measuring groove. At this time, an auxiliary guide rod parallel to the second guide rod can also be provided in the second measuring groove. The auxiliary guide rod passes vertically through the second measuring block, further limiting the up and down sliding direction of the second measuring block and effectively preventing the second measuring block from rotating along the second guide rod.

[0014] Furthermore, a pair of mounting slots are provided on the second measuring block. Each mounting slot contains a fixed rod aligned with the length direction of the first measuring slot. A movable sleeve extending horizontally backward from the second measuring block is fitted onto each of the fixed rods. The front ends of the two movable sleeves have side locking blocks that engage within the mounting slots. Their rear ends are connected to a holding plate whose lower edge is flush with the bottom surface of the second measuring block. A fourth spring is fitted onto the fixed rod in front of the side locking blocks to push the movable sleeves backward. When the second measuring block is at the lowest point of the second measuring slot, the holding plate is blocked by the front edge, causing the movable sleeve to retract within the second measuring block. When the second measuring block slides upward above the front edge, the movable sleeve, under the pushing action of the fourth spring, pushes the holding plate backward, thus enabling the holding plate to be used to measure the height of an object, thereby extending the horizontal length of the second measuring block.

[0015] The advantage of this invention is that it integrates the length measuring unit, angle measuring unit, and height measuring unit into one unit. It can measure the length of an object by sliding the first measuring block back and forth along the first measuring groove, measure the angle of an object by rotating the object-attaching upright plate synchronously with the angle alignment ruler, and measure the height of an object by sliding the second measuring block up and down along the second measuring groove. It can easily achieve rapid measurement of length, angle, and height without considering the flatness of the object surface. It is not only convenient and practical, but also ensures the accuracy of the measurement. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 As shown, the multifunctional measuring device of this utility model includes a length measuring unit, and an angle measuring unit and a height measuring unit connected to the length measuring unit.

[0025] Specifically, the length measuring unit includes a length measuring base 1, which has a rectangular strip structure. A first measuring groove 2 with its opening facing upward is horizontally arranged on its length direction, and a first scale mark 3 that is adapted to the first measuring groove 2. A front stop 4 is vertically arranged at the front end of the first measuring groove 2. A first measuring block 5 that slides back and forth along its length direction is arranged inside the first measuring groove 2. A rear stop 6 corresponding to the front stop 6 is vertically arranged at the front edge of the top of the first measuring block 5. The object to be measured can be clamped between the front stop 4 and the rear stop 6 by sliding the first measuring block 5 back and forth, so that the length of the object can be accurately identified by the first scale mark 3, and the length of the object can be measured.

[0026] To ensure the sliding stability of the first measuring block 5, a first guide rod 7, aligned with its length, should be installed in the first measuring groove 2. The first guide rod 7 passes horizontally through the center of the first measuring block 5, and a first spring 8, fitted onto the first guide rod 7, is installed in the first measuring groove 2 located behind the first measuring block 5. The first guide rod 7 enables the first measuring block 5 to slide more stably along the first measuring groove 2, while the first spring 8 pushes the sliding first measuring block 5 to automatically spring back and reset. At this time, a positioning bolt 9, whose lower end can be fixed to the first guide rod 7, should also be vertically screwed onto the top surface of the first measuring block 5. Figure 2 As shown in the figure, after the first measuring block 5 is manually pushed into place, the sliding position of the first measuring block 5 can be fixed by turning the positioning bolt 9 downward to ensure that the first measuring block 5 is stably positioned.

[0027] To improve the ease of sliding the first test block 5, such as Figure 3 As shown, the first measuring groove 2 can also be configured as a through groove running vertically through the entire length, and four sets of traveling wheels 10 extending out of the first measuring groove 2 can be provided at the bottom of the first measuring block 5. The traveling direction of the traveling wheels 10 is consistent with the sliding direction of the first measuring block 5, and the bottom surface of the four sets of traveling wheels 10 is flush with the bottom surface of the measuring base 1. This ensures that the bottom surface of the measuring base 1 can be stably attached to the ground, while making it easier and smoother for the first measuring block 5 to move back and forth along the first measuring groove 2. Furthermore, a pair of auxiliary limiting rods 11 can be installed parallel to each other at the bottom of the measuring base 1 located on the left and right sides of the first measuring block 5, which are aligned with the length direction of the first measuring groove 2. The auxiliary limiting rods 11 should extend horizontally from the bottom of the first measuring block 5 outwards through the lower retaining edge 12 of the first measuring groove 2, which can further limit the back and forth sliding direction of the first measuring block 5 and effectively prevent the first measuring block 5 from rotating along the first guide rod 7.

[0028] The angle measuring unit includes a goniometer 13, which is a horizontally arranged plate structure fixed to the upper edge of the rear guard 6. The front edge of the goniometer 13 is aligned with the front side of the rear guard 6, and a protractor 14 is horizontally extended backward on its rear edge. The upper surface of the protractor 14 is flush with the top surface of the goniometer 13 and has an angle mark 15. An angle alignment ruler 17 with horizontal rotation is hinged at the center point of the protractor 14 through a hinge pin 16. The angle alignment ruler 17 is a straight ruler structure, and a sticker stand 19 is connected to it through a pair of horizontally forward elastic telescopic members 18. The two sets of elastic telescopic members 18 are symmetrically arranged on the left and right sides of the hinge pin 16, and the sticker stand 19 keeps its length direction parallel to the length direction of the angle alignment ruler 17. The sticker stand 19 should also have a measuring state where it extends forward beyond the rear guard 6 and a storage state where it is retracted into the goniometer 13.

[0029] To allow for easy switching between the measuring and storage states of the mounting plate 19, such as... Figure 4 , 5 As shown, each set of elastic telescopic components 18 includes a mounting block 18.1 fixed to the top surface of the angle alignment ruler 17. A push rod 18.2 that slides back and forth is horizontally inserted through the mounting block 18.1. The length direction of the push rod 18.2 should be perpendicular to the length direction of the angle alignment ruler 17. The front end of the push rod 18.2 is vertically fixed to the rear side panel of the sticker stand 19. The rear end of the push rod 18.2 is provided with a limiting block 18.3 for locking behind the mounting block 18.1. A second spring 18.4 for pushing the sticker stand 19 forward is also fitted on the push rod 18.2 in front of the mounting block 18.1. At the same time, a pair of elastic retaining members 20 should be provided on the top surface of the angle measuring base 13 near the front edge to hold the attached upright plate 19 in a stored state. The elastic retaining member 20 includes a groove 20.1 opened on the top surface of the angle measuring base 13 and a retaining protrusion 20.2 set in the groove 20.1. The bottom of the retaining protrusion 20.2 is provided with a connecting rod 20.3 that passes vertically downward through the angle measuring base 13. A third spring 20.4 located in the groove 20.1 is fitted on the connecting rod 20.3. The lower end of the connecting rod 20.3 is provided with an anti-dislodgement block 20.5 that can be locked under the angle measuring base 13.

[0030] The height measuring unit includes a height measuring base 21, which has a C-shaped structure and is vertically fixed to the front end of the length measuring base 1. The height measuring base 21 has a second measuring groove 22 facing the top of the length measuring base 1, and a second scale mark 23 that is adapted to the second measuring groove 22. The second measuring groove 22 is vertically arranged, and its lower end is flush with the top surface of the length measuring base 1. A second measuring block 24 is arranged in the second measuring groove 22 and slides up and down along its height direction. The second measuring block 24 can be aligned with the top of the object to be measured by sliding up and down, so as to accurately identify the height of the object by the second scale mark 23 and realize the measurement of the height of the object.

[0031] To ensure the sliding stability of the second measuring block 24, a second guide rod 25 aligned with its height direction should be installed in the second measuring groove 22. The second guide rod 25 passes vertically through the center of the second measuring block 24, ensuring the stability of the second measuring block 24 as it slides up and down along the second measuring groove 22. Additionally, an auxiliary guide rod 26 parallel to the second guide rod 25 can be installed in the second measuring groove 22. The auxiliary guide rod 26 also passes vertically through the second measuring block 24, further limiting the up-and-down sliding direction of the second measuring block 24 and effectively preventing the second measuring block 24 from rotating along the second guide rod 25.

[0032] To ensure that the second measuring block 24 can accurately measure the top of the object, such as Figure 6 , 7 As shown, a pair of mounting slots 27 can also be opened on the second measuring block 24. The two mounting slots 27 are symmetrically opened on the left and right edges of the second measuring block 24. A fixing rod 28 is horizontally arranged in each slot, which is consistent with the length direction of the first measuring slot 2. A movable sleeve 29 that extends horizontally backward from the second measuring block 24 is respectively fitted on the two fixing rods 28. The front end of the two movable sleeves 29 has a side locking block 30 that is locked in the mounting slot 27. The rear end of the sleeves is connected to the bottom plate 31, which is flush with the bottom surface of the second measuring block 24, by means of a holding plate 31. The fixing rod 28 in front of the side locking block 30 is also connected to the side locking block 30. It is also equipped with a fourth spring 32 that pushes the movable sleeve 29 backward; when the second measuring block 24 is at the lowest end of the second measuring groove 22, the holding plate 31 is blocked by the front stop 4, causing the movable sleeve 29 to retract into the second measuring block 24. When the second measuring block 24 slides upward to above the front stop 4, the movable sleeve 29 can push the holding plate 31 backward under the pushing action of the fourth spring 32, thereby extending the horizontal length of the second measuring block 24. This allows the lower edge of the holding plate 31 to be used to press against the top of the object to be measured, thus accurately measuring the height of the object.

[0033] When it is necessary to measure the length of the object to be measured, simply move the first measuring block 5 backward so that the part of the object to be measured is between the front edge 4 and the rear edge 6. At this time, read the corresponding first scale mark 3 according to the sliding position of the first measuring block 5, and thus easily complete the length measurement of the object to be measured.

[0034] When it is necessary to measure the angle of the object to be measured, simply pull down the anti-disengagement block 20.5, causing the connecting rod 20.3 to retract the locking protrusion 20.2 into the groove 20.1, thereby releasing the object-mounting plate 19. This allows the object-mounting plate 19 to change from the storage state to the measurement state and be attached to the surface of the object to be measured. At this time, the object-mounting plate will rotate according to the angle of the surface of the object to be measured, causing the parallel angle alignment ruler 17 to rotate. Thus, according to the angle marking 15 on the protractor 14, the angle of the object to be measured can be easily measured.

[0035] When it is necessary to measure the height of the object to be measured, simply move the second measuring block 24 upward. When the second measuring block 24 slides upward to above the front edge 4, the movable sleeve 29 pushes the holding plate 31 backward under the pushing action of the fourth spring 32. At this time, the lower edge of the holding plate 31 can be used to press against the top of the object to be measured, and the corresponding second scale mark 23 can be read according to the sliding position of the second measuring block 24, thus easily completing the height measurement of the object to be measured.

[0036] The entire device integrates the length measurement unit, angle measurement unit, and height measurement unit into one unit, which can easily realize the measurement of length, angle, and height without considering the flatness of the object surface. It is not only convenient and practical, but also ensures the accuracy of the measurement.

[0037] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0038] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
