Technical Field

[0001] This utility model relates to the field of hardness tester technology, specifically to a weight-reducing shell for a hardness tester. Background Technology

[0002] In the field of industrial testing, hardness testers are key equipment for measuring the hardness of materials. Their housings not only need to provide structural support and protection for the internal precision testing components, but also need to be portable to adapt to testing operations in different scenarios. Currently, the design of hardness tester housings on the market has obvious shortcomings: on the one hand, to ensure structural strength, most housings adopt a solid structure design, which, while meeting protection requirements, results in a large overall weight, increasing the difficulty of handling and moving the equipment. To solve the above problems, this utility model provides a weight-reducing housing for hardness testers. Utility Model Content

[0003] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a weight-reducing housing for a hardness tester. The housing is equipped with multiple first and second weight-reducing holes, which can reduce the overall weight of the hardness tester and facilitate the handling and movement of the equipment.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a weight-reducing shell for a hardness tester, comprising: The housing has a plurality of first weight-reducing holes and a plurality of second weight-reducing holes, and a first sealing cap and a second sealing cap are respectively movably engaged inside the first weight-reducing holes and the second weight-reducing holes.

[0005] Preferably, the first weight-reducing hole is rectangular in shape, the second weight-reducing hole is circular in shape, the shape of the first sealing cap is adapted to the shape of the first weight-reducing hole, and the shape of the second sealing cap is adapted to the shape of the second weight-reducing hole.

[0006] Preferably, a fixing frame is fixedly installed on the side wall of the first weight reduction hole, and the inner diameter of the fixing frame is smaller than the inner diameter of the first sealing cover; A frame is fixedly installed on the first sealing cover. The fixed frame is provided with a slot that matches the frame, and the slot and the frame are interference fit.

[0007] Preferably, the end of the insertion frame facing the bottom sidewall of the slot has two outwardly convex arc shapes, and the two sides of the slot have corresponding slots.

[0008] Preferably, the insert frame is made of an elastic material and has a hollow structure.

[0009] Preferably, the end of the insert frame facing the bottom sidewall of the slot is an outwardly convex arc shape, and a top frame is fixedly installed on the bottom sidewall of the slot.

[0010] Preferably, both ends of the first sealing cover are slidably mounted with slide rods. One end of the slide rod is a forked end and the other end is a fused end. The forked end of the slide rod extends into the interior of the insert frame and is fixedly connected to the arc-shaped inner walls on both sides of the insert frame. A fixing rod is fixedly mounted on the fused end of the slide rod. The fixing rod is flush with the outer surface of the first sealing cover. A clearance groove is provided on one side of the fixing rod and on the outer surface of the first sealing cover.

[0011] Preferably, a spring sheet is fixedly installed on the side wall of the relief groove away from the fixing rod, and the spring sheet is flush with the outer surface of the first sealing cover under its own elastic force.

[0012] Preferably, a plurality of locking blocks are fixedly installed on the inner side of the second sealing cover.

[0024] 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.

[0025] This utility model provides a weight-reducing shell for a hardness tester, such as... Figures 1 to 3 As shown.

[0026] Example 1: A weight-reducing housing for a hardness tester includes a housing 1, which serves as a support carrier for the precision testing components inside the hardness tester. Multiple first weight-reducing holes 2 and multiple second weight-reducing holes 3 are respectively opened on the surface of the housing 1. The overall weight is directly reduced by reducing the amount of material used in the housing 1. The first weight-reducing holes 2 are rectangular in shape, and the second weight-reducing holes 3 are circular in shape. This shape design can be flexibly distributed according to the structural strength requirements of different areas of the housing 1, avoiding the problem of insufficient local strength caused by a single shape of weight-reducing holes.

[0027] To prevent external dust and impurities from entering the housing 1 through the weight reduction holes and affecting the performance of the components, a first sealing cover 4 is movably engaged inside the first weight reduction hole 2, and a second sealing cover 5 is movably engaged inside the second weight reduction hole 3. The shape of the first sealing cover 4 is completely adapted to the shape of the first weight reduction hole 2, and the shape of the second sealing cover 5 is completely adapted to the shape of the second weight reduction hole 3.

[0028] The first weight-reducing hole 2 and the second weight-reducing hole 3 together undertake the task of reducing the weight of the shell 1, reducing the difficulty of equipment handling; at the same time, the first sealing cover 4 and the second sealing cover 5 respectively form a closed structure for the corresponding weight-reducing holes, blocking the entry path of external pollutants. Example 2: A fixing frame 6 is fixedly installed on the side wall of the first weight reduction hole 2, and the inner diameter of the fixing frame 6 is smaller than the inner diameter of the first sealing cover 4. This design can limit the first sealing cover 4 through the fixing frame 6, preventing the first sealing cover 4 from falling off the housing 1. Correspondingly, a plug frame 7 is fixedly installed on the side of the first sealing cover 4 facing the fixing frame 6. A slot 8 that matches the plug frame 7 is opened on the side of the fixing frame 6 facing the plug frame 7, and the slot 8 and the plug frame 7 adopt an interference fit. The interference fit can initially improve the tightness of the connection between the two.

[0029] The insert frame 7 is designed as a hollow structure made of elastic material. The two sides of the end of the insert frame 7 facing the bottom side wall of the slot 8 are designed as outwardly convex arcs. At the same time, slots that fit the arc shape are opened on the two side walls of the slot 8. The hollow structure of the elastic material gives the insert frame 7 the ability to deform. The cooperation between the arc shape and the slots allows the insert frame 7 to form a locking effect after being inserted into the slot 8. In addition, a top frame 9 is fixedly installed on the bottom side wall of the slot 8. The end face of the insert frame 7 near the bottom side wall of the slot 8 is designed as an outwardly convex arc. When the insert frame 7 is inserted into the slot 8, the top frame 9 will press against the end face of the insert frame 7 near the bottom side wall of the slot 8, so that the two side walls of the insert frame 7 can fit more tightly with the two side walls of the slot 8.

[0030] To facilitate the disassembly of the first sealing cover 4, slide rods 10 are slidably installed at both ends of the first sealing cover 4. One end of the slide rod 10 is designed as a forked end and the other end as a fused end. The forked end extends into the interior of the insert frame 7 and is fixedly connected to the inner arc-shaped walls on both sides of the insert frame 7. The fused end is fixedly installed with a fixing rod 11, which is flush with the outer surface of the first sealing cover 4 to prevent the fixing rod 11 from protruding and causing bumps. A relief groove 12 is opened on one side of the fixing rod 11 and on the outer surface of the first sealing cover 4. A spring piece 13 is fixedly installed on the groove wall of the relief groove 12 away from the fixing rod 11. Under its own elastic force, the spring piece 13 is flush with the outer surface of the first sealing cover 4 and can block the opening of the relief groove 12, thereby playing a sealing and protective role.

[0031] When installing the first sealing cover 4, the insert frame 7 is aligned with the slot 8 and a pushing force is applied. The insert frame 7 undergoes elastic deformation due to the pressure of the inner wall of the slot 8. When its arc-shaped end reaches the slot position, the insert frame 7 resets and is inserted into the slot. At the same time, under the pressing action of the top frame 9, the insert frame 7 and the slot wall of the slot 8 fit more tightly, achieving a stable connection.

[0032] During disassembly, press the spring piece 13, and then pull the fixing rod 11 toward the opening of the relief groove 12. This allows the arc shape of the two side walls of the insertion frame 7 to be pulled toward the middle of the insertion frame 7 via the slide rod 10, thereby allowing the insertion frame 7 to better disengage from the slot 8 and facilitating the removal of the first sealing cover 4.

[0033] Example 3: Multiple locking blocks 14 are fixedly installed on the inner side of the second sealing cover 5. The multiple locking blocks 14 are evenly distributed along the circumference of the second sealing cover 5 to ensure force balance. The end of the locking block 14 away from the second sealing cover 5 is folded in a direction away from the axis of the second sealing cover 5. One side of the folded part is designed to be a flat surface that fits against the inner side of the housing 1, and the other side is designed to be a wedge-shaped surface that is easy to insert.

[0034] When installing the second sealing cover 5, align the second sealing cover 5 with the second weight reduction hole 3, so that the wedge-shaped surface of the locking block 14 first contacts the edge of the second weight reduction hole 3, and continue to apply the pushing force. The wedge-shaped surface is subjected to the squeezing force of the edge of the second weight reduction hole 3, which causes the locking block 14 to undergo elastic deformation in the direction closer to the axis of the second sealing cover 5, until the locking block 14 completely passes through the second weight reduction hole 3. At this time, the locking block 14 is released from the squeezing and resets under its own elastic action. The plane of the folded part is tightly fitted with the inner side of the housing 1, thereby movably locking the second sealing cover 5 into the second weight reduction hole 3 and preventing the second sealing cover 5 from falling off.

[0035] To facilitate the disassembly of the second sealing cover 5, a sliding shaft 15 is slidably installed on the second sealing cover 5. The distance between the sliding shaft 15 and the inner side of the second sealing cover 5 is less than the distance between the locking block 14 and the inner side of the second sealing cover 5. The end of the sliding shaft 15 near the locking block 14 is fixedly connected to the end of the locking block 14 away from the second sealing cover 5 through multiple connecting rods. The end away from the locking block 14 extends to the outer side of the second sealing cover 5 and folds outwards to form a frustum. During disassembly, the sliding shaft 15 is pulled away from the second sealing cover 5, so that the connecting rod can pull the locking block 14 so that the locking block 14 is no longer attached to the inner side of the housing 1, and then the second sealing cover 5 can be removed.

[0036] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
