Abstract
Description
Technical Field
[0001] This utility model applies to the field of metrology, and in particular relates to a metrological weight. Background Technology
[0002] Currently, square weights are tools used to measure the weight of objects. Their square shape makes them suitable for measurements with lower precision requirements. Square weights are primarily used for the calibration, standardization, counterweighting, and weighbridge adjustment of electronic scales, weighbridges, and other weighing instruments. By combining weights of different sizes, items of varying weights can be measured accurately, ensuring the accuracy and reliability of the weighing instrument.
[0003] However, in current weighing and measurement methods, multiple sets of weights are needed depending on the specific measurement requirements. When combining multiple sets of weights, they are often simply stacked together without fixing the positions of adjacent weights. This leads to the stacked weights easily sliding during weighing, affecting the accuracy of the measurement results. Therefore, we propose a new type of metrological weight. Utility Model Content
[0004] The main purpose of this invention is to provide a measuring weight that can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A measuring weight includes a weight body, wherein a first reinforcing post is vertically fixedly installed on each of the four top corners of the weight body, and a limit slot is vertically opened inside each of the four bottom corners of the weight body.
[0007] The weight body has a second limiting post fixedly installed horizontally on each of the four corners of its side surface, and the weight body has a movable groove horizontally opened inside each of the four corners of its other side surface.
[0008] A sealing mechanism is installed inside the movable groove.
[0009] As an optional solution to the technical solution of this application, the sealing mechanism includes a dustproof baffle. A dustproof baffle is slidably installed on the end of the inner sidewall of each movable groove away from the second limiting post. A push spring is movably sleeved inside each movable groove, and the side of the push spring is movably attached to the outside of the dustproof baffle.
[0010] As an optional solution to the technical solution of this application, each of the dustproof baffles has a guide block fixedly installed on both ends of its side surface, and the movable groove has a guide groove at both ends of its side surface, with the guide block slidably inserted into the guide groove.
[0011] As an optional solution to the technical solution of this application, the weight body has slots at the middle of both ends of its side.
[0012] As an optional solution to the technical solution of this application, the first reinforcing column and the limiting slot are in the same vertical position, and the second limiting column and the movable slot are in the same horizontal position.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. A metrological weight according to the present application has a first limiting post and a limiting slot respectively set on the upper and lower sides of the weight body, and the first limiting post and the limiting slot are in the same vertical position. This allows the first limiting post at the top of the lower weight body to be inserted into the limiting slot at the bottom of the upper weight body when the weight bodies are stacked vertically. When the weight bodies are stacked horizontally, the second limiting post is pushed horizontally into the movable groove. Combined with the insertion limiting action of the movable groove on the second limiting post in the longitudinal direction and the insertion limiting action of the limiting slot on the first limiting post in the vertical direction, the stability of stacking multiple sets of weight bodies from different directions can be achieved, avoiding arbitrary relative sliding of the weight bodies during placement, which would interfere with the metrological accuracy.
[0015] 2. A measuring weight according to the technical solution of this application has a dustproof baffle slidably installed inside a horizontally set movable groove, and a push spring is provided on the side of the dustproof baffle. The dustproof baffle can be pushed by the push spring to be located at the outermost edge of the movable groove, thereby achieving dustproof protection treatment inside the movable groove, preventing external dust and impurities from drifting into the movable groove and accumulating inside, thus affecting the overall mass of the weight and improving the measuring accuracy of the weight.

[0020] like Figure 1-3As shown, this utility model provides a technical solution: a measuring weight, wherein a first limiting post is vertically fixedly installed on the four corners of the top of the weight body 1, a limiting slot 21 is vertically opened inside the four corners of the bottom of the weight body 1, a second limiting post 22 is horizontally fixedly installed on the four corners of the side of the weight body 1, and a movable groove 23 is horizontally opened inside the four corners of the other side of the weight body 1. A sealing mechanism is set inside the movable groove 23. The first limiting post and the limiting slot 21 are in the same vertical position, and the second limiting post 22 and the movable groove 23 are in the same horizontal position. With the cooperation of the first limiting post and the limiting slot 21, and with the abutment and limiting effect of the movable groove 23 on the second limiting post 22, the stability of stacking multiple sets of weight bodies 1 from different directions can be achieved, avoiding arbitrary relative sliding of the weight bodies 1 during placement, which would interfere with the measuring accuracy.
[0021] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown, the sealing mechanism includes a dustproof baffle 3. A dustproof baffle 3 is slidably installed on the end of the inner wall of each movable groove 23 away from the second limiting post 22. A push spring 31 is movably sleeved inside each movable groove 23, and the side of the push spring 31 is movably attached to the outside of the dustproof baffle 3. After the push spring 31 is squeezed and becomes elastic, even if the push spring 31 is fully deformed and has the maximum push force, its push force is still less than the weight of the weight body 1. This prevents the push spring 31 from pushing against the weight and causing relative displacement when the weights are stacked. Under the structural action of the push spring 31, a corresponding restoring push force can be provided to the dustproof baffle 3, thereby ensuring that the dustproof baffle 3 can always be in the rightmost position of the movable groove 23 for dustproof treatment.
[0022] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown, each dust baffle 3 has a guide block 32 fixedly installed on both sides of its surface. The movable groove 23 has a guide groove 33 on both sides of its surface. The guide block 32 is slidably inserted into the guide groove 33. Under the guiding sliding action of the guide groove 33 on the guide block 32, the dust baffle 3 can only move horizontally inside the movable groove 23 when it is pushed, and will not move arbitrarily to the side, thus affecting the dust protection quality inside the movable groove 23.
[0023] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown, a slot 4 is provided at the middle of both ends of the side of the weight body 1. The shape of the slot 4 is adapted to the shape of the front end of the weight tweezers. Through the structure of the slot 4, it is convenient for the operator to use the tweezers to pick up and process the weight body 1.
[0024] During operation, when it is necessary to pick up the weight body 1, use appropriate weight tweezers to engage the front end of the weight body 1 with the slots 4 on both sides, then pick up the weight body 1 and place it on the surface of the corresponding measuring tool for weighing. Repeat the above steps, align the first limiting post at the top of the weight body 1 with the limiting slot 21 at the bottom of the upper weight body 1, then push the upper weight body 1 onto the top surface of the lower weight body 1, and stack the two sets of weight bodies 1 vertically. When combining the weight bodies 1 horizontally, simply pick up the weight body 1 and push the second limiting post 22 on its side into the movable slot 2. Inside the 3, the weight body 1 is continuously pushed, causing the second limiting post 22 to simultaneously push the dust baffle 3. Combined with the guiding sliding action of the guide groove 33 on the guide block 32, the dust baffle 3 moves inward synchronously inside the movable groove 23, compressing the push spring 31 and making it elastic. Even after the push spring 31 is fully deformed and has the maximum pushing force, its pushing force is still less than the weight of the weight body 1. Combined with the limiting action of the movable groove 23 on the second limiting post 22, the two sets of weights can be limited in the longitudinal direction, and the stacked weight bodies 1 can be assembled and fixed from multiple directions.
