[0001] This utility model relates to the field of building material testing technology, specifically a building material hardness testing device. Background Technology

[0002] Hardness testing of building materials is a crucial quality control step, directly impacting the safety and durability of buildings. Hardness testing is typically used to assess a material's resistance to indentation, abrasion, or deformation; therefore, it is a vital aspect of ensuring project quality.

[0003] In existing building material hardness testing devices, to increase the stability of the testing process, the building materials are usually fixed to the testing equipment with clamps. This means that when it is necessary to test the hardness of different parts of the building material, the clamps need to be loosened, the position of the building material needs to be readjusted, and then it needs to be fixed back with clamps. This makes it inconvenient to quickly test the hardness of different parts of the building material. Utility Model Content

Detailed Implementation

[0023] 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.

[0024] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a building material hardness testing device, comprising: a base 1 and a pressure block 4, a support frame 2 is installed on the top of the base 1, a cylinder 3 is installed on the top of the support frame 2, and the pressure block 4 is installed at the bottom of the cylinder 3.

[0025] exist Figure 1 and Figure 2 In the middle, the top of the base 1 is provided with a sliding groove, and the top of the sliding groove is slidably connected to a movable seat 5, and a clamp 6 is installed on the top of the movable seat 5.

[0026] The building material hardness testing device places the building material to be tested on the movable seat 5, and then clamps the building material with the clamp 6. The clamp 6 is mainly composed of a screw, a guide rod, a guide block and a clamping block. The guide block and the screw are connected by a thread, and the screw is connected to the clamping block through a bearing. Therefore, when the screw is rotated, the clamping block will move through the guide rod and clamp the building material.

[0027] exist Figure 2 and Figure 4 In the middle, a through groove is provided on one side of the base 1, and two sets of pawls 7 are symmetrically arranged in the through groove of the base 1. A connecting column 8 is installed on one side of the movable seat 5 through the through groove of the base 1.

[0028] The building material hardness testing device allows the movable seat 5 to slide through the groove at the top of the base 1. At the same time, when the movable seat 5 slides, the connecting column 8 on one side will slide synchronously along the through groove on the side of the base 1.

[0029] exist Figure 4 and Figure 5In the middle of the connecting post 8, a groove is provided, and a connecting shaft 9 is connected through the groove of the connecting post 8. A spring 10 is connected between the connecting shaft 9 and the groove of the connecting post 8. Both ends of the connecting shaft 9 are connected to arc-shaped blocks 11 that pass through the connecting post 8. The arc-shaped blocks 11 and the connecting shaft 9 are an integrated structure, and the arc-shaped blocks 11 and the connecting shaft 9 form a rotating structure.

[0030] The building material hardness testing device rotates the connecting shaft 9, causing the arc-shaped block 11 to rotate. When the arc-shaped block 11 rotates, it separates from the pawl 7 in the through groove on the side of the base 1. Without the pawl 7 and the arc-shaped block 11 limiting the connecting column 8, the movable seat 5 can slide along the sliding groove on the top of the base 1. At the same time, when the connecting shaft 9 rotates, the spring 10 in the groove of the connecting column 8 will tighten. When the movable seat 5 is adjusted to the appropriate position, the connecting shaft 9 is released. At this time, the spring 10 will drive the connecting shaft 9 to rotate in the opposite direction, and the connecting shaft 9 will drive the arc-shaped block 11 to rotate in the opposite direction. At this time, the arc-shaped block 11 will engage with the pawl 7 in the through groove on the side of the base 1. Due to the limiting effect of the two symmetrically arranged pawls 7 on the connecting column 8, the movable seat 5 cannot slide.

[0031] exist Figure 2 and Figure 3 In the middle, a fixed frame 12 is installed on the top of the base 1. A sliding groove is opened on one side of the fixed frame 12, and a connecting rod 13 is slidably connected in the sliding groove on one side of the fixed frame 12. The end of the connecting rod 13 away from the fixed frame 12 is connected to a fixed rod 14. A push plate 15 is installed at the bottom of the two sets of fixed rods 14. The push plate 15 is set on the top of the movable seat 5.

[0032] The building material hardness testing device pushes the push plate 15, causing the push plate 15 to slide along the sliding groove on the side of the fixed frame 12 via the fixed rod 14 and the connecting rod 13, thereby pushing the waste chips on the movable seat 5 to move synchronously.

[0033] exist Figure 6 In the middle, a fixing block 16 is installed on one side of a set of fixing brackets 12. The top of the fixing block 16 has a through slot, and a spring 17 is installed inside the slot. A locking block 18 is installed on the top of the spring 17.

[0034] The building material hardness testing device, through the reset action of the spring 17, will push the locking block 18 to move upward along the movable groove of the fixed block 16. At this time, the locking block 18 can limit the connecting rod 13, thereby ensuring that the push plate 15 will not move arbitrarily.

[0035] exist Figure 1 and Figure 4 In the middle, the top of the movable seat 5 is provided with a slag discharge port 19, and a slot is provided on one side of the base 1, and a collection box 20 is slidably connected in the slot on one side of the base 1.

[0036] The building material hardness testing device can push the waste on the movable seat 5 into the slag discharge port 19 through the push plate 15, and then fall into the collection box 20 in the groove on the side of the base 1 through the slag discharge port 19, thus facilitating the collection of waste.

[0037] exist Figure 1 In the middle, the top of the collection box 20 is provided with an eccentric wheel 21, which is connected to one side of the base 1 via a rotating shaft.

[0038] The building material hardness testing device rotates the eccentric wheel 21 upwards so that the eccentric wheel 21 does not limit the collection box 20, and then the collection box 20 can be slid out from the slot on the side of the base 1. Conversely, when the eccentric wheel 21 is released, the eccentric wheel 21 will rotate downwards under the action of gravity, and at this time the collection box 20 can be limited in the slot on the side of the base 1.

[0039] In summary, when using this building material hardness testing device, the building material to be tested can be placed on the movable seat 5 and fixed by the clamp 6. Then, the cylinder 3 at the top of the support frame 2 drives the pressure block 4 to move downward and squeeze the building material on the movable seat 5. At this time, the hardness of the building material can be tested. This is the characteristic of the use of this building material hardness testing device. The contents not described in detail in this description belong to the prior art known to those skilled in the art.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
