Description

Technical Field

[0001] The utility model relates to the technical field of toughened glass detection, in particular to an impact-resistant toughened glass strength detector. Background Technique

[0002] Toughened glass is a kind of prestressed glass with high safety. To improve the strength of the glass, chemical or physical methods are usually used to form compressive stress on the glass surface. When the glass bears external force, the surface stress is offset first, thus improving the bearing capacity, enhancing the wind pressure resistance, cold and heat resistance, impact resistance, etc. of the glass itself. The strength of toughened glass is several times higher than that of ordinary glass. When in use, due to the increase in its bearing capacity, the fragile property is improved, resulting in small fragments without sharp corners when the toughened glass is damaged, reducing the harm to the human body.

[0003] In the prior art, such as the Chinese patent publication number CN220323003U, an impact-resistant toughened glass strength detector is disclosed, including a detection table and a detection needle. A rotating rod is rotatably connected to the inner walls on both sides of the detection table. A U-shaped block is fixedly connected to the outer walls of the two rotating rods. Four threaded rods are equidistantly and threadedly connected to the outer walls of the two U-shaped blocks. One end of each of the several threaded rods passes through a screw hole and extends into the corresponding U-shaped block and is rotatably connected to a vacuum suction cup. One end of the two rotating rods passes through the detection table through a bearing and is fixedly sleeved with a rotating gear. A receiving square tank is fixedly connected to the outer walls on both sides of the detection table below the rotating gear. A top block is slidably connected to the inner walls of the two receiving square tanks. The detection needle impacts the toughened glass for testing, which can simulate the impacts on the toughened glass at different angles and improve the detection intensity of the impact resistance of the toughened glass.

[0004] Although the above patent can simulate the impacts on the toughened glass at different angles and improve the detection intensity of the impact resistance of the toughened glass, however, the existing toughened glass strength detectors usually use a detection needle falling from a height to impact the toughened glass and then judge the impact resistance strength of the toughened glass through its integrity. However, the height of the detection needle for impact cannot be flexibly adjusted. Therefore, only a fixed value of impact force can be provided to the toughened glass, and the detection result is relatively one-sided. Therefore, in view of the above problems, we propose a new type of impact-resistant toughened glass strength detector. Content of the Utility Model

However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited to the limitations of the specific embodiments disclosed in the following specification.

[0024] Embodiment 1, as Figures 1 - 5 shown, the present utility model provides an impact-resistant toughened glass strength detector, including a sliding sleeve 2. A toothed column 21 is slidably arranged inside the sliding sleeve 2. A detection needle 22 is connected to the bottom of the toothed column 21. A release mechanism 3 is arranged at a position near the bottom of the outer surface of the sliding sleeve 2. A lifting mechanism 4 is arranged at the top of the sliding sleeve 2. The release mechanism 3 includes a mounting frame 301. Slide rods 302 are symmetrically and slidably penetrated and connected to the right surface of the mounting frame 301. A connecting rod 303 is fixedly connected between the right ends of the two slide rods 302. A meshing block 305 is fixedly connected between the left ends of the two slide rods 302. A spring 306 is fixedly connected between the right surface of the meshing block 305 and the inner wall of the right side of the mounting frame 301. An electric push rod 304 is installed on the right surface of the mounting frame 301. The position of the electric push rod 304 corresponds to that of the connecting rod 303. A chute 24 is opened at a position near the bottom of the outer surface of the sliding sleeve 2. The outer surface of the meshing block 305 is slidably fitted with the inner wall of the chute 24. One-way meshing teeth are arranged on the outer surfaces of both the meshing block 305 and the toothed column 21. The mounting frame 301 is fixedly connected to the outer surface of the sliding sleeve 2. Connecting frames 12 are symmetrically and fixedly connected to the outer surface of the sliding sleeve 2. A storage rack 1 is fixedly connected between the bottom ends of the two connecting frames 12. A supporting frame 11 is fixedly connected between the inner walls of the storage rack 1. The lifting mechanism 4 includes two mounting plates 401. The two mounting plates 401 are symmetrically and fixedly connected to the top of the sliding sleeve 2. A rotating shaft 402 is rotatably connected between the outer surfaces of the two mounting plates 401. A wire wheel 403 is fixedly connected to the outer surface of the rotating shaft 402. A connecting rope 404 is wound around the outer surface of the wire wheel 403. The bottom end of the connecting rope 404 is fixedly connected to the top of the toothed column 21. A motor 405 is installed on the outer surface of one of the mounting plates 401. The output end of the motor 405 penetrates the outer surface of the mounting plate 401 and is fixedly connected to one end of the rotating shaft 402.

[0025] The effect achieved by the entire embodiment 1 is that when the device is used to perform impact resistance testing on a tempered glass sample, the tempered glass is first placed on the top of the inner support frame 11 of the rack 1, and then the electric push rod 304 is started to push the connecting rod 303 to move to the right. At this time, the connecting rod 303 drives the engagement block 305 to move to the right through the slide rod 302 and compresses the spring 306. When the engagement block 305 and the tooth column 21 inside the sliding sleeve 2 are separated, the tooth column 21 loses its limit and falls downward under the action of gravity. When the detection needle 22 under the tooth column 21 hits the tempered glass on the top of the supporting frame 11, the product can be judged whether it is qualified according to the completion degree of the tempered glass. In addition, when the device is in use, the motor 405 is started to drive the rotating shaft 402 to rotate. At this time, the wire wheel 403 on the surface of the rotating shaft 402 will reel the connecting rope 404 onto the surface. During the reeling process of the connecting rope 404, the tooth column 21 and the detection needle 22 will be pulled upward. When the tooth column 21 enters the interior of the sliding sleeve 2 and moves upward, the single The meshing teeth will squeeze the one-way meshing teeth on the surface of the meshing block 305, so that the meshing block 305 is repeatedly pushed out from the inside of the sliding sleeve 2. When the meshing teeth are staggered, the spring 306 rebounds and squeezes the meshing block 305 to re-enter the inside of the sliding sleeve 2 and mesh with the tooth column 21. By cooperating with a large number of meshing teeth on the surface of the tooth column 21, the tooth column 21 can be restricted to move to any height inside the sliding sleeve 2. After the tooth column 21 moves to a suitable height, the motor 405 drives the rotating shaft 402 and the wire wheel 403 to reverse and release the connecting rope 404 again to keep it in a relaxed state. Then, the release mechanism 3 is cooperated to control the tooth column 21 to fall, so that the data of the detection needle 22 hitting the tempered glass after falling at different heights can be obtained, thereby improving the comprehensiveness of the tempered glass detection result, and the overall structure is simple and easy to operate. The connecting frame 12 is mainly used to connect the sliding sleeve 2 and the storage rack 1, the slide groove 24 is mainly used to accommodate the meshing block 305, and the mounting plate 401 is mainly used to install the motor 405 and the rotating shaft 402.

[0026] Embodiment 2, as Figures 1 - 4 As shown, a bell mouth 23 is fixedly connected to the bottom of the sliding sleeve 2, and the inner diameter of the bottom opening of the bell mouth 23 is larger than the inner diameter of the top opening.

[0027] The effect achieved by the entire embodiment 2 is that, during the rising process of the tooth column 21, a bell mouth 23 is provided at the bottom of the sleeve 2, and the bottom opening of the bell mouth 23 is relatively large, and the inside is smooth and gradually narrows, which plays a role in guiding the tooth column 21, so that the tooth column 21 can accurately enter the interior of the sleeve 2 after moving upward, thereby ensuring the stability and reliability of the device when in use.

[0028] Working principle: When using this device to test the impact resistance of tempered glass samples, first place the tempered glass on the top of the support frame 11 inside the shelf 1, then start the electric push rod 304 to push the connecting rod 303 to move to the right, at this time the connecting rod 303 drives the engagement block 305 to move to the right through the slide bar 302 and compresses the spring 306, when the engagement block 305 and the tooth column 21 inside the sliding sleeve 2 are separated, the tooth column 21 loses its limit and falls downward under the action of gravity, at this time the detection needle 22 under the tooth column 21 impacts the support frame 11. The quality of the product can be judged according to the degree of completion of the tempered glass on the top. In addition, when the device is in use, the motor 405 is started to drive the rotating shaft 402 to rotate. At this time, the wire wheel 403 on the surface of the rotating shaft 402 will reel the connecting rope 404 onto the surface. During the reeling process of the connecting rope 404, the tooth column 21 and the detection needle 22 will be pulled upward. When the tooth column 21 enters the interior of the sliding sleeve 2 and moves upward, the one-way meshing teeth on the surface will squeeze the one-way meshing teeth on the surface of the meshing block 305, so that the meshing block 305 is engaged. 305 is repeatedly pushed out from the inside of the sliding sleeve 2. When the meshing teeth are staggered, the spring 306 rebounds and squeezes the meshing block 305 to re-enter the inside of the sliding sleeve 2 and mesh with the tooth column 21. By cooperating with a large number of meshing teeth on the surface of the tooth column 21, the tooth column 21 can be restricted to any height inside the sliding sleeve 2. After the tooth column 21 moves to a suitable height, the motor 405 drives the rotating shaft 402 and the wire wheel 403 to reverse and release the connecting rope 404 again to keep it in a relaxed state. Then, the tooth column 21 is controlled to fall in cooperation with the release mechanism 3 to obtain data of the detection needle 22 hitting the tempered glass after falling at different heights, thereby improving the comprehensiveness of the tempered glass detection result, and the overall structure is simple and easy to operate. In addition, during the rising process of the tooth column 21, a bell mouth 23 is set at the bottom of the sliding sleeve 2. The bottom opening of the bell mouth 23 is large, the inside is smooth and gradually narrowed, which plays a role in guiding the tooth column 21, so that the tooth column 21 can accurately enter the inside of the sliding sleeve 2 after moving upward, ensuring the stability and reliability of the device when in use.
