Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel weights, in particular to a stainless steel weight which is easy to assemble. Background Art

[0002] In modern mass measurement, weights are standard measuring tools for mass value transmission. The mass value is based on the original platinum-iridium alloy kilogram preserved in the International Bureau of Weights and Measures in France as the only reference. All countries divide weights into national kilogram standards, national kilogram secondary standards, kilogram working standards, and working standards composed of multiples and components of the kilogram and various working standard weights.

[0003] Most of the existing stainless steel weights are balance weights, which can have different weight mass combinations according to the range of balance measurement, and are equipped with a set of working reference groups composed of their multiples and components, with masses from large to small, the least number of which can form any value. However, due to the large number of weights and small size, they are easy to lose and difficult to use. At the same time, the existing stainless steel weights all exist separately and lack the function of assembly and combination.

[0004] For example, the assembled stainless steel weights disclosed in Chinese patent CN215767345U are provided with standard blocks and limiting protrusions. There are several standard blocks, each of which has the same cross-section and a diameter slightly smaller than the inner diameter of the weight tube. The mass of each standard block is a preset value. The standard block can be placed in the weight tube through tweezers according to user needs, thereby forming a weight as a whole with the weight tube and the weight cover for measurement.

[0005] However, after the standard block in the stainless steel weight is placed inside the weight tube, the standard block is not fixed in the weight tube, so that when the weight tube moves, the standard block therein will cause loss due to relative friction.

[0006] For this reason, we urgently need to provide a stainless steel weight that can fix the standard block and is easy to assemble. Utility Model Content

[0007] The purpose of the utility model is to provide a stainless steel weight that is easy to assemble and combine, so as to solve the problem that after the standard block in the stainless steel weight proposed in the above background technology is placed in the weight tube, the standard block is not fixed to the weight tube, so that when the weight tube moves, the standard block therein will cause relative friction and loss.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a stainless steel weight that is easy to assemble and combine, including a weight tube and a cap, the cap is connected to the upper end of the weight tube, the inside of the weight tube is connected with an assembling mechanism, the assembling mechanism includes an assembling unit and an adjusting unit, the assembling unit is arranged inside the weight tube, and the adjusting unit is arranged at the upper end of the cap.

[0009] The assembly unit includes a threaded rod, a pressure cylinder, a standard block, a hook, a spring and an insertion rod. The threaded rod is fixedly connected to the left and right ends of the bottom side of the weight cylinder, the pressure cylinder is connected to the outside of the threaded rod, the standard block is slidably connected to the inside of the weight cylinder, the hook is fixedly connected to the upper middle position of the standard block, the spring is connected to the lower left and right ends of the cap, and the insertion rod is fixedly connected to one end of the spring.

[0010] A further improvement is that a circular groove is provided at the middle position of the left and right ends of the lower part of the inside of the cap, the end of the spring away from the insertion rod is fixedly connected to the innermost end of the circular groove, and the outer side of the insertion rod is slidably connected to the inner side of the circular groove. Therefore, when the spring is activated, the insertion rod can be driven to slide along the inner side of the circular groove, thereby limiting the movement of the insertion rod.

[0011] A further improvement is that a plug hole is provided in the middle of the left and right ends of the upper part of the weight tube, the outer side of the lower end of the cap is slidably connected to the inner side of the upper end of the weight tube, and the outer side of the end of the plug rod away from the spring is plugged into the inner side of the plug hole. Thus, by first pressing the plug rod into the circular groove, then sliding the lower end of the cap to the inner side of the upper end of the weight tube, and then the spring rebounds to push the plug rod out, so that the end of the plug rod away from the spring moves to the plug hole at the upper end of the weight tube, so that the cap can be fixed to the upper end of the weight tube.

[0012] A further improvement is that the inner side of the pressure cylinder is provided with an internal thread, a circular hole is provided in the middle of the left and right ends of the standard block, the inner side of the pressure cylinder is threadedly connected to the outer side of the threaded rod, the lower side of the pressure cylinder is in contact with the upper side of the standard block, and the outer side of the threaded rod is slidably connected to the inner side of the circular hole. Thus, after the standard block is slid to the inner side of the weight cylinder and the threaded rod passes through the circular hole, the pressure cylinder is threadedly connected to the outer side of the threaded rod until the lower side of the pressure cylinder contacts the upper side of the standard block, so that the standard block can be fixed to the weight cylinder, so that the standard block in the weight cylinder will not move relative to each other and cause wear during the movement of the weight cylinder.

[0013] A further improvement is that the adjustment unit includes a threaded plug and a connecting block, the threaded plug is connected to the middle position of the inner upper end of the cap, and the connecting block is fixedly connected to the upper end of the threaded plug.

[0014] A further improvement is that a thread groove is provided in the middle of the upper inner end of the cap, the outer side of the thread plug is threadedly connected to the inner side of the thread groove, and the lower side of the connecting block is in contact with the upper outer end of the cap. Thus, after placing iron filings in the thread groove, the thread plug is threadedly connected to the thread groove until the connecting block is fixed to the upper end of the cap, so that the iron filings can be sealed in the thread groove, so that when the weight tube and the cap are worn and become lighter, iron filings of corresponding weight can be added to the thread groove, so that the weight of the weight tube and the cap can be kept constant, thereby ensuring the accuracy of measurement.

[0015] A further improvement is that a rubber pad is fixedly connected to the lower side of the threaded plug, so that when the threaded plug is connected to the threaded groove, the rubber pad on the lower side of the threaded plug will slide along the inner side of the threaded groove to prevent iron filings in the threaded groove from entering between the threaded plug and the threaded groove, thereby affecting the normal threaded connection.

[0016] In summary, the present application discloses a stainless steel weight that is easy to assemble.

[0017] According to the technical solution, after the standard block is slid to the inner side of the weight tube and the threaded rod passes through the round hole, the pressure tube is threadedly connected to the outer side of the threaded rod until the lower side of the pressure tube contacts the upper side of the standard block. This can fix the standard block in the weight tube, so that the standard block in the weight tube will not move relative to each other and cause wear during the movement of the weight tube.

[0018] Furthermore, after the iron filings are placed in the threaded groove, the threaded plug is threadedly connected to the threaded groove until the connecting block is fixed to the upper end of the cap. This allows the iron filings to be sealed in the threaded groove. When the weight tube and the cap become lighter due to wear, iron filings of corresponding weight can be added to the threaded groove. This allows the weight of the weight tube and the cap to remain constant, thereby ensuring the accuracy of the measurement. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] See also Figure 1-Figure 6 , the utility model provides a technical solution: Example

[0028] A stainless steel weight that is easy to assemble and combine, including a weight tube 1 and a cap 2, the cap 2 is connected to the upper end of the weight tube 1, the inside of the weight tube 1 is connected with an assembling mechanism, the assembling mechanism includes an assembling unit and an adjusting unit, the assembling unit is arranged inside the weight tube 1, and the adjusting unit is arranged at the upper end of the cap 2.

[0029] The assembly unit includes a threaded rod 301, a pressure cylinder 302, a standard block 303, a hook 304, a spring 305 and a plug rod 306. The threaded rod 301 is fixedly connected to the left and right ends of the bottom side of the weight cylinder 1, the pressure cylinder 302 is connected to the outside of the threaded rod 301, the standard block 303 is slidably connected to the inside of the weight cylinder 1, the hook 304 is fixedly connected to the middle position of the upper side of the standard block 303, the spring 305 is connected to the lower left and right ends of the cap 2, and the plug rod 306 is fixedly connected to one end of the spring 305. A circular groove is provided at the middle position of the left and right ends at the lower left and right ends of the cap 2. One end of the spring 305 away from the plug rod 306 is fixedly connected to the innermost end of the inner side of the circular groove, and the outer side of the plug rod 306 is slidably connected to the inner side of the circular groove. Therefore, when the spring 305 bounces, it can drive the plug rod 306 to slide along the inner side of the circular groove, thereby limiting the movement of the plug rod 306.

[0030] A plug hole is provided at the middle position of the left and right ends of the upper part of the weight cylinder 1, and the outer side of the lower end of the cap 2 is slidably connected with the inner side of the upper end of the weight cylinder 1, and the outer side of the end of the plug rod 306 away from the spring 305 is plugged into the inner side of the plug hole. Thus, by first pressing the plug rod 306 into the circular groove, and then sliding the lower end of the cap 2 to the inner side of the upper end of the weight cylinder 1, and then the spring 305 rebounds to push the plug rod 306 out, so that the end of the plug rod 306 away from the spring 305 moves to the plug hole at the upper end of the weight cylinder 1, so that the cap 2 can be fixed to the upper end of the weight cylinder 1.

[0031] The inner side of the pressure cylinder 302 is provided with an internal thread, and a circular hole is provided in the middle of the left and right ends of the standard block 303.
