Description

Technical Field

[0001] This utility model relates to the field of measuring weights, and in particular to a measuring weight that is easy to assemble. Background Technology

[0002] In fields such as metrology, quality calibration, and traditional commercial weighing, traditional weight scales are classic mass measurement devices. The performance of their core component, the weight, directly determines the accuracy of the weighing results and the ease of operation. Traditional weight scales typically rely on monolithic weights for mass comparison; that is, each weight is a complete solid metal block with a fixed and indivisible mass. While these monolithic weights, when used with traditional weight scales, can meet basic metrological needs, they still have the following shortcomings in practical operation: Currently used weight scales typically rely on a weight holder at one end of the scale body to support the stacked weights. An opening on one side of the weight allows the rod of the weight holder to pass through, ensuring that the center of the weight is close to the rod of the weight holder, resulting in even force distribution. However, this type of weight requires a separate weight holder, and because the opening size is often larger than the diameter of the weight holder rod, the center cannot be precisely aligned with the rod, leaving room for improvement in force balance. Furthermore, the weights are simply stacked without any combination relationship, making them prone to tipping over and falling due to excessive height, causing damage. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a measuring weight that is easy to assemble, thus effectively solving the deficiencies of the prior art.

[0004] The purpose of this utility model is achieved through the following technical solution: a conveniently assembled measuring weight, comprising a weight body, a connector fixedly connected to the center of the top of the weight body, and a mating groove opened to the side at the center of the bottom of the weight body. The connector comprises a mushroom-shaped structure consisting of a connecting post and a snap-fit ​​connector. The snap-fit ​​connector is fixedly connected to the top of the connecting post and has a diameter larger than the connecting post. The mating groove comprises a lower inlet groove, an upper inlet groove, and a snap-fit ​​groove. The upper inlet groove is opened at the top of the lower inlet groove. The snap-fit ​​groove is opened at the bottom of the inner wall of the upper inlet groove, corresponding to the center of the weight body. The centerline of the lower inlet groove corresponds to the center of the upper inlet groove and the snap-fit ​​groove. The width of the upper inlet groove and the diameter of the snap-fit ​​groove are both adapted to the diameter of the snap-fit ​​connector. The width of the lower inlet groove is adapted to the diameter of the connecting post. One end of both the lower and upper inlet grooves communicates with the side of the weight body. The bottom of the lower inlet groove is connected to the bottom surface of the weight body.

[0005] Preferably, in any of the above solutions, the vertical spacing of the inner wall of the upper guide groove is adapted to the thickness of the snap-fit ​​connector, the vertical spacing of the lower guide groove is adapted to the height of the connecting column, and the depth of the snap-fit ​​groove is less than the vertical spacing of the lower guide groove.

[0006] The technical effect achieved by adopting the above solution is that the upper guide groove and the snap connector, as well as the lower guide groove and the connecting column, can fit together tightly.

[0007] Preferably, the edges of both the upper and lower surfaces of the snap-fit ​​connector are chamfered, the depth of the snap-fit ​​groove is greater than one-third of the thickness of the snap-fit ​​connector, and the snap-fit ​​groove is clearance-fitted with the snap-fit ​​connector.

[0008] The technical effect achieved by adopting the above solution is that the chamfer facilitates the insertion of the connector into the upper inlet groove and the slot, preventing obstruction.

[0009] Preferably, as described in any of the above embodiments, a circular storage groove is provided at the center of the top surface of the card connector, and a hidden hanging ring is rotatably connected to the middle of the inner wall of the circular storage groove, the hidden hanging ring being completely stored in the inner wall of the circular storage groove.

[0010] The technical effect achieved by adopting the above solution is that by rotating the hidden hanging ring, the weights can be stored inside the circular storage slot when they are combined to prevent interference.

[0011] Preferably, in any of the above solutions, the concealed hanging ring is a semi-circular structure, the center of the concealed hanging ring corresponds to the center of the snap fastener, and the top of the concealed hanging ring protrudes above the top surface of the snap fastener when it is upright.

[0012] The technical effect achieved by adopting the above scheme is that the semi-circular structure can slide the connection between the top and the weighing body to the center position after suspension, so that the vertical line of force after connection passes through the axis of the weight.

[0013] This utility model has the following advantages: 1. This easy-to-assemble measuring weight is assembled by aligning the snap-fit ​​part of the lower weight's connector with the upper guide groove of the upper weight's docking slot and pushing it in. This allows the connecting post to pass through the lower guide groove until it slides into the snap-fit ​​slot. Then, release the lower weight. Under its own weight, the snap-fit ​​part falls into the snap-fit ​​slot, achieving docking. This combination method eliminates the need for a weight holder, allowing the upper and lower weights to directly connect together. The mutual positioning and restraint of the snap-fit ​​slot and snap-fit ​​part prevent them from detaching or falling off, improving safety. At the same time, after assembly, the centers of the upper and lower weights are aligned, resulting in higher concentricity, more even force distribution, and improved weighing accuracy.

[0014] 2. This easy-to-assemble measuring weight can be stored inside a circular storage slot to prevent interference when the weights are combined with each other, thanks to a rotating hidden hanging ring. At the same time, when used alone or as the top weight, the vertical hidden hanging ring can be rotated to hang the weight on the scale body. Through its semi-circular structure, the top of the weight will slide to the center position after suspension to ensure that the vertical line of force is centered. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0018] like Figures 1 to 3 As shown, a conveniently assembled measuring weight includes a weight body 1. A connector 2 is fixedly connected to the center of the top of the weight body 1. A mating groove 5 is opened to the side at the center of the bottom of the weight body 1. The connector 2 is a mushroom-shaped structure composed of a connecting post 21 and a snap-fit ​​connector 22. The snap-fit ​​connector 22 is fixedly connected to the top of the connecting post 21 and has a diameter larger than the connecting post 21. The mating groove 5 includes a lower inlet groove 51, an upper inlet groove 52, and a snap-fit ​​groove 53. The upper inlet groove 52 is formed in the lower inlet groove 51. At the top of 1, the snap-in groove 53 is opened at the bottom of the inner wall of the upper inlet groove 52, corresponding to the center of the weight body 1. The lower inlet groove 51 corresponds to the center line of the upper inlet groove 52 and the center of the snap-in groove 53. The width of the upper inlet groove 52 and the diameter of the snap-in groove 53 are both adapted to the diameter of the snap-in connector 22. The width of the lower inlet groove 51 is adapted to the diameter of the connecting post 21. One end of the lower inlet groove 51 and the upper inlet groove 52 are connected to the side of the weight body 1. The bottom of the lower inlet groove 51 is connected to the bottom surface of the weight body 1.

[0019] As an optional technical solution of this utility model: the vertical spacing of the inner wall of the upper guide groove 52 is adapted to the thickness of the snap-fit ​​connector 22, the vertical spacing of the lower guide groove 51 is adapted to the height of the connecting post 21, and the depth of the snap-fit ​​groove 53 is less than the vertical spacing of the lower guide groove 51, so that the upper guide groove 52 and the snap-fit ​​connector 22, as well as the lower guide groove 51 and the connecting post 21, can fit together tightly.

[0020] As an optional technical solution of this utility model: the edges of the upper and lower surfaces of the snap-fit ​​connector 22 are provided with chamfers, the depth of the snap-fit ​​groove 53 is greater than one-third of the thickness of the snap-fit ​​connector 22, the snap-fit ​​groove 53 and the snap-fit ​​connector 22 are fitted with a clearance, and the chamfers facilitate the snap-fit ​​connector 22 to be guided into the upper guide groove 52 and the snap-fit ​​groove 53, preventing obstruction.

[0021] As an optional technical solution of this utility model: a circular storage groove 3 is provided at the center of the top surface of the snap connector 22, and a hidden hanging ring 4 is rotatably connected to the middle of the inner wall of the circular storage groove 3. The hidden hanging ring 4 can be completely stored in the inner wall of the circular storage groove 3. By rotating the hidden hanging ring 4, the weights can be stored inside the circular storage groove 3 to prevent interference when they are combined.

[0022] As an optional technical solution of this utility model: the hidden hanging ring 4 is a semi-circular structure. The center position of the hidden hanging ring 4 corresponds to the center position of the snap connector 22. When the hidden hanging ring 4 is erected, the top is higher than the top surface of the snap connector 22. The semi-circular structure can slide the top to the center position of the connection between the weighing body and the weight after suspension, so that the vertical line of force after connection passes through the axis of the weight.

[0023] The working process of this utility model is as follows: When the user uses it... 1) Align the snap-fit ​​part 22 of the lower weight connector 2 with the upper guide groove 52 of the upper weight docking slot 5 and push it in, so that the connecting post 21 passes through the lower guide groove 51 until it slides into the snap-fit ​​slot 53. 2) Then release the lower weight, and under its own weight, the locking connector 22 falls into the locking groove 53, realizing the docking combination of the upper and lower parts; 3) Through the above steps, multiple weights can be aligned head to head. With the mutual positioning and restriction of the slot 53 and the connector 22, they are not easy to fall off. After combination, the centers of the upper and lower weights can be aligned, resulting in higher concentricity and more uniform force distribution.

[0024] In summary, this invention allows the locking connector 22 of the lower weight connector 2 to be aligned with the upper guide groove 52 of the upper weight docking slot 5 and pushed in, so that the connecting post 21 passes through the lower guide groove 51 until it slides into the locking groove 53. Then, the lower weight is released, and under its own weight, the locking connector 22 falls into the locking groove 53, achieving docking. This combination method eliminates the need for a weight holder, allowing the upper and lower weights to directly connect together. The mutual positioning and restraint between the locking groove 53 and the locking connector 22 prevents mutual interference. The detachment and falling of the weights improve safety. When combined, the centers of the upper and lower weights are aligned, resulting in higher concentricity, more even force distribution, and improved weighing accuracy. The rotating hidden hanging ring 4 can be stored inside the circular storage slot 3 to prevent interference when the weights are combined. When used alone or as the top weight, the vertical hidden hanging ring 4 can be rotated to hang the weights on the scale body. Through its semi-circular structure, the top of the ring will slide to the center position after suspension to ensure that the vertical line of force is centered.
