Description

Technical Field

[0001] The utility model relates to the technical field of paint detection, and particularly relates to a surface hardness detection device for real stone paint. Background Technique

[0002] Real stone paint is a high-grade decorative paint with unique decorative effects and durability. Surface hardness detection is to determine whether the quality and durability of real stone paint meet the standard requirements. Through surface hardness detection, the hardness, abrasion resistance and durability of the paint can be evaluated to ensure that there will be no problems such as cracking, peeling or discoloration during long-term use. In addition, surface hardness detection can also help determine the coating uniformity and quality stability of real stone paint to ensure that its decorative effect and service life meet the expected goals. Therefore, conducting surface hardness detection is crucial for ensuring the quality and use effect of real stone paint. The gravity ball method is a relatively common detection method;

[0003] Since the existing real stone paint samples are directly placed on the detection table for impact detection during detection, once the sample is misaligned or offset during the detection process, it will directly affect the final detection result. However, the existing device has not been improved for this problem, and the overall practical effect is somewhat poor. Summary of the Utility Model

[0004] The purpose of the utility model is to propose a surface hardness detection device for real stone paint to solve the above problems, which improves the problem that the existing surface hardness detection device for real stone paint directly places the real stone paint sample on the detection table for impact detection, and once the sample is misaligned or offset during the detection process, it will directly affect the final detection result.

[0005] A surface hardness detection device for real stone paint includes a support base and a detection table: a detection table is slidably installed on the outer wall of the top end of the support base, an auxiliary moving mechanism is arranged below the detection table, a locking and positioning mechanism is arranged above the detection table, and a detection control mechanism is arranged above the locking and positioning mechanism. The auxiliary moving mechanism includes a limit T-shaped groove, a limit T-shaped block, a positioning block, a limit bolt and a threaded hole. Limit T-shaped grooves are symmetrically opened on the outer wall of the top end of the support base. Limit T-shaped blocks are symmetrically arranged on the outer wall of the bottom end of the detection table at the middle position. The limit T-shaped block and the limit T-shaped groove are slidably installed. A positioning block is arranged on the outer wall of the side of the detection table at the middle position. A threaded hole is penetrated and opened on the outer wall of the top end of the positioning block. A limit bolt is threadedly installed inside the threaded hole, and threaded holes are equidistantly opened on the outer wall of the top end of the support base.

[0006] Preferably, the locking and positioning mechanism includes a mounting block, a support shaft, an auxiliary block, and a positioning frame. Mounting blocks are symmetrically arranged on the outer wall of the top end of the detection table. The side outer wall of the mounting block is an open structure, and a support shaft is rotatably installed between the inner walls on both sides of the mounting block. An auxiliary block is arranged on the outside of the support shaft, and the side outer wall of the auxiliary block is connected to the side outer wall of the positioning frame.

[0007] Preferably, the bottom outer wall of the positioning frame is an open structure, and limiting sleeves are equidistantly arranged on the inner wall of the top end of the positioning frame. A limiting piston rod is slidably installed inside the limiting sleeve, and the protruding end of the limiting piston rod is located below the limiting sleeve.

[0008] Preferably, the protruding end of the limiting piston rod is connected to the top outer wall of an elastic cushion. A resisting spring is connected between the top outer wall of the limiting piston rod and the inner wall of the top end of the positioning frame. A resisting block is arranged on the side outer wall of the positioning frame, and resisting grooves are symmetrically formed on the outer wall of the top end of the detection table. The resisting block and the resisting grooves are snap-fitted.

[0009] Preferably, the detection and control mechanism includes a positioning support frame, a placement box, and a conduit. A positioning support frame is arranged on the outer wall of the top end of the support base. The positioning support frame is in an inverted "L" shape, and a placement box is arranged on the outer wall of the top end of the positioning support frame.

[0010] Preferably, a conduit is conductively installed on the bottom outer wall of the placement box, and a strip-shaped groove is formed on the side outer wall of the bottom end of the placement box.

[0011] Preferably, a limiting baffle is snap-fitted inside the strip-shaped groove, and the limiting baffle is slidably installed on the side inner wall of the placement box.

[0012] Preferably, a gravity ball is arranged above the limiting baffle, and the gravity ball is located inside the placement box.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. When the real stone paint surface hardness detection device is in use, through the settings of the mounting block, support shaft, auxiliary block, positioning frame, limiting sleeve, limiting piston rod, elastic cushion, and resisting spring, the elastic cushion can be tightly attached to the upper part of the real stone paint sample by using the reaction force of the spring to resist and support, so that the real stone paint sample can be stably placed above the detection table by increasing the contact friction force. With the snap-fitting effect of the resisting block and the resisting groove to lock the positioning frame, the real stone paint sample can be stably positioned above the detection table through the above settings, so that the real stone paint sample will not be displaced or offset during the detection, thus ensuring the detection accuracy of the subsequent detection work, and the overall practical effect is good;

[0015] 2. When the surface hardness detection device for the real stone paint is in use, the detection table can freely move on the surface of the support base through the setting of the limit T-shaped groove and the limit T-shaped block. With the setting of the positioning block, the limit bolt and the threaded hole, the positioning and locking effect of the detection table can be achieved. Furthermore, the design that the detection table can move flexibly enables the device to detect different positions of the real stone paint sample. Then, by comprehensively taking the average value of multiple detection results, the final detection result is more accurate. At the same time, the device only needs to position the real stone paint sample once at the initial stage of detection, and subsequent multi-point detection can be achieved without repeatedly adjusting the position of the real stone paint sample, and the overall detection effect is good.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] In specific implementation: As Figures 1-5 shown, a surface hardness detection device for real stone paint includes a support base 1 and a detection table 2: A detection table 2 is slidably installed on the outer wall of the top end of the support base 1. An auxiliary moving mechanism 3 is arranged below the detection table 2, a locking and positioning mechanism 4 is arranged above the detection table 2, and a detection control mechanism 5 is arranged above the locking and positioning mechanism 4. The auxiliary moving mechanism 3 includes a limit T-shaped groove 31, a limit T-shaped block 32, a positioning block 33, a limit bolt 34, and a threaded hole 35. Limit T-shaped grooves 31 are symmetrically opened on the outer wall of the top end of the support base 1. Limit T-shaped blocks 32 are symmetrically arranged on the outer wall of the bottom end of the detection table 2 at the middle position. The limit T-shaped blocks 32 and the limit T-shaped grooves 31 are slidably installed. A positioning block 33 is arranged on the outer wall of the side of the detection table 2 at the middle position. A threaded hole 35 is penetrated and opened on the outer wall of the top end of the positioning block 33. A limit bolt 34 is threadedly installed inside the threaded hole 35, and threaded holes 35 are equidistantly opened on the outer wall of the top end of the support base 1; When it is necessary to move the position of the detection table 2 to adjust the sample to different test positions, first, the limit bolt 34 needs to be screwed out from the inside of the threaded hole 35. Then, the detection table 2 changes from the locked state to the movable state. Subsequently, the detection table 2 is pushed to slide on the outer wall of the support base 1. When the detection table 2 moves, it will automatically drive the limit T-shaped block 32 to slide inside the limit T-shaped groove 31 and play a limiting and supporting effect on the movement of the detection table 2. When the detection table 2 moves to a suitable position, at this time, the limit bolt 34 passes through the positioning block 33 and is screwed into the threaded hole 35 at the corresponding position to lock the detection table 2 again.

[0024] The locking and positioning mechanism 4 includes a mounting block 41, a support shaft 42, an auxiliary block 43 and a positioning frame 44. Mounting blocks 41 are symmetrically arranged on the top outer wall of the detection table 2. The side outer wall of the mounting block 41 is an open structure, and a support shaft 42 is rotatably installed between the two inner walls of the mounting block 41. An auxiliary block 43 is arranged outside the support shaft 42. The side outer wall of the auxiliary block 43 is connected to the side outer wall of the positioning frame 44. The bottom outer wall of the positioning frame 44 is an open structure, and a plurality of limiting sleeves 45 are equidistantly arranged on the top inner wall of the positioning frame 44. A limiting piston rod 46 is slidably installed inside the limiting sleeve 45. The extending end of the limiting piston rod 46 is located below the limiting sleeve 45. The extending end of the limiting piston rod 46 is connected to the top outer wall of the elastic cushion 47. A contact spring 48 is connected between the top outer wall of the limiting piston rod 46 and the top inner wall of the positioning frame 44. A contact latch 49 is arranged on the side outer wall of the positioning frame 44. Contact slots 410 are symmetrically formed on the top outer wall of the detection table 2. The contact latch 49 and the contact slots 410 are snap-fitted; when it is necessary to position the real stone paint sample to be tested above the detection table 2, first, the real stone paint sample needs to be adjusted to a proper position and then placed above the detection table 2. Subsequently, the handle above the positioning frame 44 is pulled to drive the positioning frame 44 to move downward. Then, the movement of the positioning frame 44 will automatically drive the auxiliary block 43 to rotate outside the support shaft 42. Here, the setting of the mounting block 41 plays a role in limiting and supporting the support shaft 42. Subsequently, the downward displacement of the positioning frame 44 will automatically drive the elastic cushion 47 to move downward. When the elastic cushion 47 contacts the real stone paint sample during the movement, the elastic cushion 47 is displaced upward under the contact action of the real stone paint sample and automatically drives the limiting piston rod 46 to slide inside the limiting sleeve 45. Then, the contact spring 48 is in a contracted state under the contact action of the limiting piston rod 46. At the same time, the contact spring 48 generates a reaction force under the extrusion action to push the limiting piston rod 46 to displace in the reverse direction. When the limiting piston rod 46 moves in the reverse direction, it will automatically push the elastic cushion 47 to closely fit on the outer wall of the real stone paint sample. When the positioning frame 44 is moving, it will also drive the contact latch 49 to snap into the contact slots 410. When the contact latch 49 snaps into the contact slots 410, the positioning of the real stone paint sample is completed. It should be noted here that there is friction when the contact latch 49 and the contact slots 410 are snap-fitted and they will not easily fall off automatically.

[0025] The detection control mechanism 5 includes a positioning support frame 51, a placement box 52, and a conduit 53. The outer wall of the top end of the support base 1 is provided with a positioning support frame 51. The positioning support frame 51 is set in an inverted "L" shape, and the outer wall of the top end of the positioning support frame 51 is provided with a placement box 52. The outer wall of the bottom end of the placement box 52 is conductively installed with a conduit 53. A strip-shaped groove 54 is opened on the outer wall of the side at the bottom of the placement box 52. A limit baffle 55 is snap-fitted inside the strip-shaped groove 54. The limit baffle 55 is slidably installed on the inner wall of the side of the placement box 52, and a gravity ball 56 is arranged above the limit baffle 55. The gravity ball 56 is located inside the placement box 52. When the imitation stone paint sample needs to be subjected to hardness detection after being positioned, first, the limit baffle 55 needs to be pulled out from the inside of the placement box 52. Then, the gravity ball 56 will lose the block and will automatically perform a free-fall motion under the guidance of the conduit 53. Subsequently, by measuring the diameter of the pit formed on the outer wall of the imitation stone paint sample, the hardness of the detected imitation stone paint sample can be directly understood. The larger the diameter of the pit, the smaller the hardness of the imitation stone paint sample, and vice versa, the smaller the diameter of the pit, the greater the hardness of the imitation stone paint sample.

[0026] When the present utility model is in use, when it is necessary to position the imitation stone paint sample to be measured above the detection table 2, first, the imitation stone paint sample needs to be adjusted to a suitable position and then placed above the detection table 2. Subsequently, the handle above the positioning frame 44 is pulled to drive the positioning frame 44 to move downward. Then, the movement of the positioning frame 44 will automatically drive the auxiliary block 43 to rotate outside the support shaft 42. Here, the installation block 41 plays a role in limiting and supporting the support shaft 42. Subsequently, the downward displacement of the positioning frame 44 will automatically drive the elastic cushion 47 to move downward. When the elastic cushion 47 comes into contact with the imitation stone paint sample during the movement, the elastic cushion 47 is displaced upward under the contact action of the imitation stone paint sample and automatically drives the limit piston rod 46 to slide inside the limit sleeve 45. Then, the contact spring 48 is in a contracted state under the contact action of the limit piston rod 46. At the same time, the contact spring 48 generates a reaction force under the extrusion action to push the limit piston rod 46 to move in the reverse direction. When the limit piston rod 46 moves in the reverse direction, it will automatically push the elastic cushion 47 to closely fit on the outer wall of the imitation stone paint sample. When the positioning frame 44 is moving, it will also drive the contact block 49 to be stuck into the contact slot 410. When the contact block 49 is stuck into the contact slot 410, the positioning of the imitation stone paint sample is completed. It should be noted here that there is friction when the contact block 49 and the contact slot 410 are engaged and they will not easily fall off automatically.

[0027] When hardness testing is required after the imitation stone paint coating sample is positioned, first, the limit baffle 55 needs to be pulled out from the inside of the placement box 52. Then, the gravity ball 56 will lose its block and automatically fall freely under the guidance of the conduit 53. Subsequently, by measuring the diameter of the pit formed on the outer wall of the imitation stone paint coating sample, the hardness of the tested imitation stone paint coating sample can be directly understood. The larger the diameter of the pit, the smaller the hardness of the imitation stone paint coating sample; conversely, the smaller the diameter of the pit, the greater the hardness of the imitation stone paint coating sample. When it is necessary to move the position of the test bench 2 to adjust the sample to different test positions, first, the limit bolt 34 needs to be screwed out from the inside of the threaded hole 35. Then, the test bench 2 changes from the locked state to the movable state. Subsequently, the test bench 2 is pushed to slide on the outer wall of the support base 1. When the test bench 2 moves, it will automatically drive the limit T-shaped block 32 to slide inside the limit T-shaped groove 31 and play a role in limiting and supporting the movement of the test bench 2. When the test bench 2 moves to the appropriate position, at this time, the limit bolt 34 passes through the positioning block 33 and is screwed into the threaded hole 35 at the corresponding position to lock the test bench 2 again. Subsequently, repeat the above test steps to test different positions of the imitation stone paint coating sample, and take the average value after comprehensive comparison as the hardness value of the imitation stone paint coating sample.

[0028] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
