Description

Technical Field

[0001] The utility model relates to the technical field of green building material hardness detection, in particular to green building material hardness detection equipment. Background Art

[0002] Green building materials are non-toxic, non-polluting, and non-radioactive building materials produced using clean production technologies, using minimal or no natural resources and energy, and utilizing a significant amount of industrial, agricultural, or municipal solid waste. They are recyclable after their lifecycle and are beneficial to environmental protection and human health. The definition of green building materials encompasses four key aspects: raw material selection, product manufacturing, use, and waste disposal. These objectives aim to minimize the impact on the global environment and benefit human health, ultimately achieving the four goals of "health, environmental protection, safety, and quality." Hardness testing equipment is required for hardness testing of green building materials.

[0003] When using the existing pen-type hardness testing device, one hand is required to support the pen-type hardness testing device, and the other hand is required to press the button on the top of the pen-type hardness testing device to test the hardness of the material. However, when a narrow space is required, it is difficult to use the pen-type hardness testing device with both hands. Therefore, it is necessary to optimize a green building material hardness testing device through technological innovation and design optimization. Utility Model Content

[0004] When using the existing pen-type hardness testing device, one hand is required to support the pen-type hardness testing device, and the other hand is required to press the button on the top of the pen-type hardness testing device to test the hardness of the material. However, when a narrow space is required, it is difficult to use the pen-type hardness testing device with both hands. In order to solve the above problems, the embodiment of the present application provides a green building material hardness testing device. By setting a pressing mechanism, the hardness tester can be operated with one hand, avoiding the inability to use the hardness tester with both hands when encountering a narrow space. At the same time, by setting a limiting mechanism, the U-shaped frame can be disassembled and assembled, which is convenient for disassembly and assembly of the U-shaped frame according to different usage scenarios.

[0005] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0006] A green building material hardness testing device, comprising:

[0007] Hardness tester;

[0008] Among them, a U-shaped frame for easy grasping is provided on the top of the hardness tester, and a pressing mechanism is provided on the U-shaped frame. Fixed blocks are fixed on both sides of the hardness tester, and a limiting mechanism is provided between the fixed blocks and the U-shaped frame.

[0009] In a possible implementation, the U-shaped frame includes two insertion rods, and a connecting rod is fixed between the two insertion rods to facilitate single-handed grasping.

[0010] In one possible implementation, the pressing mechanism includes a rectangular plate provided at the bottom of the connecting rod, rectangular grooves are provided on the facing surfaces of the two insertion rods, rectangular blocks are slid in the two rectangular grooves, and the two rectangular blocks are fixedly connected to the rectangular plate. A pressing rod is provided on the top of the connecting rod, and a guide column is fixed at the bottom of the pressing rod. The guide column passes through the insertion rod and is fixedly connected to the rectangular block. Grasp the connecting rod and the moving rod with one hand and grip it hard, the moving rod will move in the direction of the connecting rod, the connecting rod will drive the guide column to move, the guide column will drive the rectangular block to slide downward in the rectangular groove, and the rectangular block will drive the rectangular plate to move downward, and then press the button of the hardness tester downward, so that the hardness of the material can be tested with one hand.

[0011] In one possible implementation, a spring 1 is provided between the pressing rod and the connecting rod, and the spring set is provided on the outside of the guide column. When the moving rod moves toward the connecting rod, it will squeeze the spring 1, and the spring 1 will give the moving rod a force in the opposite direction, so that when no pressure is applied to the moving rod, the moving rod can be reset under the action of the spring.

[0012] In one possible implementation, a slot is provided on the top of the fixing block, the insertion rod can be inserted into the slot, and a limiting hole is provided at one end of the fixing block away from the hardness tester, and the limiting hole is connected to the slot to facilitate fixing the insertion rod and the fixing block.

[0013] In one possible implementation, the limiting mechanism includes limiting grooves provided on opposite surfaces of the two insertion rods, a limiting block provided in the limiting groove, and a second spring provided in the limiting groove. When the insertion rod is inserted into the slot, the limiting block will be squeezed into the limiting groove when it contacts the fixed block, and the limiting block will compress the second spring at the same time. When the limiting block is aligned with the limiting hole, the limiting block will be inserted into the limiting hole under the action of the second spring, completing the fixation of the insertion rod and the fixed block. The insertion rod can be pulled out by pressing the limiting block, thereby completing the quick disassembly and assembly of the insertion rod and the fixed block.

[0014] In a possible implementation, the end of the limit block away from the spring 2 is provided with an inclined surface, and the inclined surface is opened downward, so that the fixing block can squeeze the limit block into the limit groove without manual pressing.

[0015] In a possible implementation, one end of the second spring is fixedly connected to the limiting block, and the other end of the second spring is fixedly connected to the insertion rod to prevent the limiting block from falling off from the limiting groove.

[0016] In summary, the present invention has at least one of the following beneficial technical effects:

[0017] 1. By grasping the moving rod firmly, the moving rod will move toward the connecting rod, which will drive the guide column to move. The guide column will drive the rectangular block to slide downward in the rectangular groove. The rectangular block will drive the rectangular plate downward, and then press the button of the hardness tester downward, which is convenient for testing the hardness of the material with one hand in narrow spaces.

[0018] 2. By inserting the plug rod into the slot, the limit block will be squeezed into the limit slot when it contacts the fixed block. At the same time, the limit block compresses spring 2. When the limit block is aligned with the limit hole, the limit block will be inserted into the limit hole under the action of spring 2, completing the fixation of the plug rod and the fixed block. Press the limit block to pull out the plug rod, thereby completing the quick disassembly and assembly of the plug rod and the fixed block, making it easy to disassemble and assemble the U-shaped frame according to the scenario.

[0024] The following will be combined with the drawings in the present invention to clearly and completely describe the technical solution of the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The instrument placement rack involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] This embodiment introduces the specific structure of a green building material hardness testing device. Figure 1-Figure 4 As shown, a green building material hardness testing device includes:

[0026] Hardness tester 1;

[0027] Among them, the top of the hardness tester 1 is provided with a U-shaped frame for easy grasping, and the U-shaped frame is provided with a pressing mechanism. Fixed blocks 2 are fixed on both sides of the hardness tester 1, and a limiting mechanism is provided between the fixed block 2 and the U-shaped frame.

[0028] When one hand is needed, the U-shaped frame includes two insertion rods 4, and a connecting rod 6 is fixed between the two insertion rods 4, which is convenient for single-handed grasping.

[0029] When encountering a narrow corner and needing to press the button of the hardness tester 1 with one hand to test the hardness of the material, the pressing mechanism includes a rectangular plate 8 provided at the bottom of the connecting rod 6, and rectangular grooves 3 are provided on the facing surfaces of the two insertion rods 4. Rectangular blocks 11 are sliding in the two rectangular grooves 3, and the two rectangular blocks 11 are fixedly connected to the rectangular plate 8. A pressing rod 5 is provided on the top of the connecting rod 6, and a guide column 10 is fixed at the bottom of the pressing rod 5. The guide column 10 passes through the insertion rod 4 and is fixedly connected to the rectangular block 11. Grasp the connecting rod 6 and the moving rod with one hand, and grasp it hard. The moving rod will move in the direction of the connecting rod 6, and the connecting rod 6 will drive the guide column 10 to move. The guide column 10 will drive the rectangular block 11 to slide downward in the rectangular groove 3, and the rectangular block 11 drives the rectangular plate 8 to move downward, and then press the button of the hardness tester 1 downward, which is convenient for testing the hardness of the material with one hand.

[0030] When the moving rod is released, a spring 7 is provided between the pressing rod 5 and the connecting rod 6. The spring 7 is sleeved on the outside of the guide column 10. When the moving rod moves toward the connecting rod 6, the spring 7 is squeezed. The spring 7 gives the moving rod a force in the opposite direction, so that when no pressure is applied to the moving rod, the moving rod is reset under the action of the spring.

[0031] In addition, a slot 12 is provided on the top of the fixing block 2, and the insertion rod 4 can be inserted into the slot 12. A limiting hole 15 is provided on the end of the fixing block 2 away from the hardness tester 1, and the limiting hole 15 is connected to the slot 12, which facilitates the fixing of the insertion rod 4 and the fixing block 2.

[0032] When the U-shaped frame needs to be disassembled and assembled in different scenarios, the limiting mechanism includes limiting grooves 14 opened on the opposite sides of the two insertion rods 4, a limiting block 9 is provided in the limiting groove 14, and a spring 2 13 is provided in the limiting groove 14. When the insertion rod 4 is inserted into the slot 12, the limiting block 9 will be squeezed into the limiting groove 14 when it contacts the fixing block 2. At the same time, the limiting block 9 compresses the spring 2 13. When the limiting block 9 is aligned with the limiting hole 15, the limiting block 9 will be inserted into the limiting hole 15 under the action of the spring 2 13, completing the fixation of the insertion rod 4 and the fixing block. The insertion rod 4 can be pulled out by pressing the limiting block 9, thereby completing the rapid disassembly and assembly of the insertion rod 4 and the fixing block 2.

[0033] It is worth noting that the end of the limit block 9 away from the spring 2 13 is set as an inclined surface, and the inclined surface is opened downward, which makes it easier for the fixed block 2 to squeeze the limit block 9 into the limit groove 14 without manual pressing.

[0034] When the limit block 9 moves, one end of the second spring 13 is fixedly connected to the limit block 9 , and the other end of the second spring 13 is fixedly connected to the insertion rod 4 to prevent the limit block 9 from falling off from the limit groove 14 .

[0035] The model of the hardness tester 1 is Linshang LS252DL Leeb hardness tester.

[0036] When the staff encounters a narrow space and cannot use both hands to operate, the insertion rod 4 is inserted into the slot 12. When the limit block 9 contacts the fixed block 2, it will be squeezed into the limit groove 14. At the same time, the limit block 9 compresses the spring 2 13. When the limit block 9 is aligned with the limit hole 15, the limit block 9 will be inserted into the limit hole 15 under the action of the spring 2 13, completing the fixation of the insertion rod 4 and the fixed block. Pressing the limit block 9 can pull out the insertion rod 4, thereby completing the quick disassembly and assembly of the insertion rod 4 and the fixed block 2. Grasp the moving rod and the pressing rod 5 with one hand, press the hardness tester 1 against the material to be tested, grasp the moving rod hard, and the moving rod will move in the direction of the connecting rod 6. The connecting rod 6 will drive the guide column 10 to move, and the guide column 10 will drive the rectangular block 11 to slide downward in the rectangular groove 3. The rectangular block 11 drives the rectangular plate 8 to move downward, and then presses the button of the hardness tester 1 downward, which is convenient for testing the hardness of the material with one hand.

[0037] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments.
