DETAILED DESCRIPTION

[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the following is a summary of the technical problems, technical solutions and beneficial effects to be solved by the present invention. Figure 1-9 It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0030] Reference Figure 1-Figure 5A multifunctional valve measuring device includes a base 1, a height measuring ruler 2, a universal angle ruler 3 and a locking member 4, wherein the universal angle ruler 3 includes an angle base ruler 31 and a ruler 32, the angle base ruler 31 is set to be fan-shaped, and the ruler 32 is hinged to the center of the angle base ruler 31, so that one end of the ruler 32 points to the scale of the angle base ruler 31. The height dimension of the valve bend is measured by the height measuring ruler 2, the bending angle dimension of the valve is measured by the angle base ruler 31, and the length dimension of the valve is measured by the ruler 32. And the end of the ruler 32 pointing to the scale of the angle base ruler 31 is set to be sharp, so as to facilitate the angle reading on the angle base ruler 31.

[0031] The height measuring ruler 2 is fixedly arranged vertically on the base 1. In order to enable the universal angle ruler 3 to keep rising and falling on the height measuring ruler 2, a guide plate 33 is extended on one side of the angle base ruler 31. The straight line where the guide plate 33 is located passes through the zero scale line of the scale of the angle base ruler 31. Correspondingly, a guide hole 11 is vertically opened in the base 1, so that the guide plate 33 is inserted into the guide hole 11 of the base 1. When the universal angle ruler 3 is in the process of rising and falling, the guide plate 33 rises and falls in the guide hole 11. The setting of the guide plate 33 plays a guiding role in the rising and falling of the universal angle ruler 3. When the universal angle ruler 3 is raised and lowered to a suitable height, the universal angle ruler 3 and the height measuring ruler 2 are locked and fixed by the locking member 4. A second limiting bolt 331 is fixedly provided at the bottom end of the guide plate 33, and the second limiting bolt 331 is located at the bottom end of the base 1. The second limiting bolt 331 limits the lifting of the guide plate 33 to prevent the guide plate 33 from lifting excessively and falling off from the guide hole 11. By adjusting the relative height between the universal angle ruler 3 and the base 1, the measuring device can detect different types of valves.

[0032] A positioning groove 12 is formed on the surface of the base 1, and a waist-shaped hole 14 is formed at the center of the positioning groove 12. The length direction of the waist-shaped hole 14 points to the zero scale line of the angle base scale 31, and a positioning column 13 is arranged in the waist-shaped hole 14. The top of the positioning column 13 protrudes from the waist-shaped hole 14 and can move along the length direction of the waist-shaped hole 14. When it is necessary to measure the valve, one end of the valve top surface of the valve is embedded in the positioning groove 12 of the base 1, and the positioning column 13 is inserted into the valve, so that the valve is accurately positioned and installed on the base 1, and then the universal angle ruler 3 is adjusted in height. By moving the positioning column 13 in the waist-shaped hole 14, different types of valves can be accurately positioned and installed in the positioning groove 12. After the valves of different types are installed in the positioning groove 12, it can be ensured that the valve corresponds to the zero scale line of the angle base scale 31.

[0033] The locking member 4 includes a locking bolt 41 and a locking plate 42, and a through hole 421 is formed on the surface of the locking plate 42. A through slot 21 is formed in the height measuring ruler 2 along its length direction, a first hinge hole 311 is formed at the center of the angle base ruler 31, and a hinge shaft 323 is provided on the surface of the ruler 32, and the hinge shaft 323 is inserted into the first hinge hole 311, thereby realizing the hinge connection between the ruler 32 and the angle base ruler 31. A screw hole 321 is formed through the ruler 32 and the hinge shaft 323, and the locking bolt 41 is inserted into the through hole 421 and the through slot 21 in turn and is screwed and fixed in the screw hole 321, thereby realizing the fixation between the universal angle ruler 3 and the height measuring ruler 2. The locking bolt 41 is screwed and fixed in the screw hole 321, which not only firmly fixes the universal angle ruler 3 and the height measuring ruler 2, but also has the advantage of convenient adjustment.

[0034] Reference Figure 6 and Figure 7 In addition, a sliding groove 22 is formed in the measuring plate along its length direction, so that the through groove 21 is located in the sliding groove 22, and the locking plate 42 is inserted into the sliding groove 22 so that the surface of the locking plate 42 is flush with the surface of the height measuring ruler 2. When the universal angle ruler 3 is adjusted in height, the locking plate 42 slides in the sliding groove 22 of the height measuring ruler 2. A scale indicator line 422 is provided on the surface of the locking plate 42. When adjusting, the locking bolt 41 is loosened from the screw hole 321, and then the height of the angle base ruler 31 and the ruler 32 is adjusted so that the hinge of the angle base ruler 31 and the ruler 32 is located at the bend of the valve. The scale value on the height measuring ruler 2 pointed to by the scale indicator line 422 on the surface of the locking plate 42 is the height dimension of the bend of the valve.

[0035] Reference Figure 8 and Fig. 9In order to accurately measure the bending angle of the valve, a sliding block 34 is provided on the ruler 32. For this purpose, a sliding hole 341 is formed in the sliding block 34. The ruler 32 is inserted into the sliding hole 341 of the sliding block 34, so that the sliding block 34 can slide along the surface of the ruler 32, and a clamping groove 342 is formed on the surface of the sliding block 34 facing the angle base scale 31. After the universal angle ruler 3 is adjusted to a suitable height position, the ruler 32 is rotated so that the angle between the ruler 32 and the height measuring ruler 2 corresponds to the bending angle of the valve, so that one end of the valve tail end face of the valve is clamped in the clamping groove 342. At this time, the scale value on the angle base scale 31 pointed by the sharp end of the ruler 32 is the bending angle of the valve. One end of the valve tail end face of the valve nozzle is embedded in the embedding groove 342 to ensure that the ruler 32 and the valve nozzle are in the same straight line to ensure the accuracy of the valve nozzle bending angle measurement. In addition, a first limiting bolt 322 is provided at the end of the ruler 32 away from the angle base plate, and the first limiting bolt 322 limits the sliding block 34 to prevent the sliding block 34 from falling off from the ruler 32.

[0036] The specific implementation principle of the embodiment of the present application is as follows: when it is necessary to measure the valve, one end of the valve top surface of the valve is embedded in the positioning groove 12 of the base 1, and the positioning column 13 is inserted into the valve. Then, the locking bolt 41 is loosened, and the universal angle ruler 3 is raised, so that the hinge between the angle base ruler 31 and the ruler 32 is located at the bend of the valve, and the locking bolt 41 is locked and fixed in the screw hole 321. The position of the sliding block 34 on the ruler 32 is moved, so that one end of the tail end face of the valve is embedded in the embedding groove 342 of the sliding block 34. At this time, the angle value on the angle base ruler 31 pointed by the pointed end of the ruler 32 is the bending angle of the valve. Finally, the scale value on the ruler 32 pointed by one end of the tail end face of the valve is the length dimension of the valve. The multifunctional valve measuring device can adapt to the measurement of valves of different models by adjusting the relative height size of the universal angle ruler 3 and the angle between the ruler 32 and the height measuring ruler 2.

[0037] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all protected by the utility model.
