Description

Technical Field

[0001] This utility model relates to the field of glass testing technology, specifically to a stress tester for chemical strengthening of glass panels. Background Technology

[0002] The stress tester for chemical strengthening of glass panels is a specialized device used to evaluate and quantify the internal stress distribution of glass during the chemical strengthening process. Chemical strengthening is a method to improve the strength and scratch resistance of glass. Its working principle is to change the composition and structure of the glass surface through chemical means, so that a compressive stress layer is formed on the surface and a tensile stress layer is formed inside, thereby improving the impact resistance. This stress tester is an important tool in the field of glass chemical strengthening technology, and plays a key role in ensuring material performance, improving product quality, and ensuring user safety.

[0003] Chinese Patent Publication No. (CN212432384U) discloses a glass stress tester, including a tester body and a protective cover. The protective cover is hinged to the tester body to cover the upper surface of the tester body. The protective cover includes a dustproof part and a fitting part. The dustproof part is a box-shaped part with one open end and is formed by splicing five dustproof plates. The fitting part is used to fit with the lens on the tester body. The tester body is provided with a storage box for placing a lint-free cloth. The upper surface of the storage box is open, and a dust cover is slidably connected to the upper surface of the storage box.

[0004] The protective cover in the aforementioned comparative document is mainly connected to the detection box via a hinge axis, but the entire document does not mention any support structure at the hinge. When the protective cover is opened to any angle, if the center of gravity exceeds the vertical line of the hinge axis, it will automatically rotate in the closing direction due to its own gravity, which may pose a safety risk of pinching fingers or colliding with the glass.

[0005] In view of this, the present invention solves the above-mentioned technical problems by proposing a stress tester for chemical strengthening of glass panels. Utility Model Content

[0006] To address the shortcomings of the aforementioned background technology, this utility model provides a technical solution for a stress tester for chemical strengthening of glass panels. By using the main arm and auxiliary arm, it completely solves the problem of the protective cover automatically closing due to gravity in the prior art, avoiding the risk of pinching hands or colliding with the glass. At the same time, when the triangular block and triangular slot are locked, a triangular geometric lock is formed to prevent the arm body from rotating due to gravity, thus forming a double protection. Finally, the ring array of slots supports locking at any angle from 0-90°, adapting to different operating scenarios.

[0007] This utility model provides the following technical solution: a stress tester for chemical strengthening of glass panels, including a test box, an LED emitting light, a protective cover hinged to the top of the test box, and a lens disposed on the top of the test box;

[0008] The top of the detection box and the bottom of the protective cover are symmetrically provided with two sets of mounting slots. Each set of mounting slots is rotatably connected to a main arm and a secondary arm through a hinge shaft. The main arm and the secondary arm are hinged together by a pin to form a folding arm assembly.

[0009] At least one sliding groove is provided on the side of the main arm near the auxiliary arm. A sliding block is slidably connected in the sliding groove. A triangular locking block is fixedly connected to the side of the sliding block facing the auxiliary arm. A return spring is provided between the sliding block and the sliding groove. The return spring is used to drive the sliding block to slide towards the auxiliary arm.

[0010] The auxiliary arm has multiple triangular slots on the side closest to the main arm. The triangular blocks engage with the triangular slots to lock the relative angle between the main arm and the auxiliary arm.

[0011] As a preferred technical solution of this utility model, the sliding groove and the triangular slot are arranged in a circular array, and there are 8 of them. The angle between the triangular block and the triangular slot is an acute angle, and the maximum unfolding angle between the main arm and the auxiliary arm is 90°.

[0012] As a preferred technical solution of this utility model, a magnetic suction plate is embedded on the opposite edge of the detection box and the protective cover, and the magnetic suction plate is a neodymium iron boron permanent magnet magnetic suction plate.

[0013] As a preferred embodiment of this utility model, the main arm and the auxiliary arm are aluminum alloy main arm and aluminum alloy auxiliary arm, and the outer ring of the hinge shaft of the main arm and the auxiliary arm is fitted with a damping bearing.

[0014] As a preferred technical solution of this utility model, the surface of the triangular card block is provided with an anti-slip coating, which is a polytetrafluoroethylene anti-slip coating.

[0015] As a preferred embodiment of this utility model, the inner edge of the protective cover is provided with a rubber sealing strip. The cross-section of the rubber sealing strip is trapezoidal, which is used to tightly fit the top of the detection box when closed, so as to prevent dust from entering the lens area.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By using the main arm and auxiliary arm, the problem of the protective cover automatically closing due to gravity in the existing technology is completely solved, avoiding the risk of pinching hands or colliding with the glass. At the same time, when the triangular block and triangular slot are locked, a triangular geometric lock is formed to prevent the arm body from rotating due to gravity, thus forming a double protection. Finally, the slot of the ring array supports locking at any angle from 0-90°, adapting to different operating scenarios (such as small-angle ventilation and large-angle sample placement).

[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] Please see Figure 1-5 As shown, a stress tester for chemical strengthening of glass panels includes a test box 1, an LED emitting light 101, a protective cover 102 hinged to the top of the test box 1, and a lens 103 disposed on the top of the test box 1.

[0026] The testing box 1 is used to carry optical components (LED emitting light 101, lens 103) and provides a testing operation platform;

[0027] The hinged design of the protective cover 102 enables the opening and closing function, and its core function is to protect the lens 103 from dust contamination (corresponding to the defect of "exposed lens is easy to get dust in" in the existing technology);

[0028] The LED emitter 101 and lens 103 form an optical detection path, which measures glass stress through the principle of light refraction.

[0029] The top of the detection box 1 and the bottom of the protective cover 102 are symmetrically provided with two sets of mounting slots 2. Each set of mounting slots 2 is rotatably connected to the main arm 201 and the auxiliary arm 202 through a hinge shaft. The main arm 201 and the auxiliary arm 202 are hinged by a pin to form a folding arm assembly.

[0030] Mounting slot 2 is used for concealed storage. When folded, the main arm 201 and the auxiliary arm 202 are embedded between the detection box 1 and the protective cover 102, without adding extra space and keeping the equipment compact.

[0031] At least one sliding groove 203 is provided on the side of the main arm 201 near the auxiliary arm 202. A sliding block 204 is slidably connected in the sliding groove 203. A triangular locking block 205 is fixedly connected to the side of the sliding block 204 facing the auxiliary arm 202. A return spring 206 is provided between the sliding block 204 and the sliding groove 203. The return spring 206 is used to drive the sliding block 204 to slide towards the auxiliary arm 202.

[0032] The return spring 206 is used to provide a continuous thrust to ensure that the triangular latch 205 always tends to be in the latching state, and locking can be achieved without manual operation;

[0033] The sliding block 204 and sliding groove 203 are used to limit the movement trajectory of the locking block, prevent tilting and jamming, and improve locking reliability;

[0034] The triangular bevel of the triangular locking block 205 can provide mechanical self-locking capability. After locking, it can withstand lateral force and prevent the folding arm from being accidentally unlocked due to external force (compared to the automatic closing caused by the lack of support in the existing technology).

[0035] The auxiliary arm 202 has multiple triangular slots 207 on the side near the main arm 201. The triangular block 205 engages with the triangular slot 207 to lock the relative angle between the main arm 201 and the auxiliary arm 202.

[0036] The sliding groove 203 and the triangular slot 207 are arranged in a circular array, and there are 8 of them. The angle between the triangular block 205 and the triangular slot 207 is an acute angle. The maximum unfolding angle of the main arm 201 and the auxiliary arm 202 is 90°.

[0037] The 8-ring array triangular slots 207 can achieve angle adjustment in 11.25° increments within the range of 0-90° (such as 30°, 45°, 60°, etc.), adapting to different operating needs (such as observing data at small angles and placing glass samples at large angles);

[0038] The acute angle design balances locking strength and unlocking resistance (too small an angle can cause jamming, while too large an angle results in insufficient locking force), ensuring smooth operation.

[0039] A magnetic suction plate 3 is embedded on the edge of the opposite side of the detection box 1 and the protective cover 102. The magnetic suction plate 3 is a neodymium iron boron permanent magnet magnetic suction plate.

[0040] The magnetic force of a single magnetic plate 3 is 2-5N, which is used to enhance the sealing performance when the protective cover 102 is closed;

[0041] The main boom 201 and the auxiliary boom 202 are aluminum alloy main boom and aluminum alloy auxiliary boom, and the outer ring of the hinge shaft of the main boom 201 and the auxiliary boom 202 is equipped with a damping bearing.

[0042] The surfaces of the main boom 201 and the auxiliary boom 202 are both anodized, with a thickness of 3-6mm. The surface oxide layer is corrosion-resistant and wear-resistant, extending the service life of the main boom 201 and the auxiliary boom 202.

[0043] The damping bearing 4 has a rotational resistance torque of 0.1-0.3 N·m. The 0.1-0.3 N·m resistance torque is used to slow down the rotation speed of the main arm 201 and the auxiliary arm 202, avoid rapid opening and closing impact on the detection box 1 or the protective cover 102, and protect optical components (such as the lens 103).

[0044] The surface of the triangular block 205 is provided with an anti-slip coating, which is a polytetrafluoroethylene anti-slip coating.

[0045] The anti-slip coating has a thickness of 0.1-0.3mm and is used to increase the friction between the triangular block 205 and the triangular slot 207.

[0046] The thickness control of 0.1-0.3mm can avoid the coating being too thick, which would cause the triangular block 205 and the triangular slot 207 to not mesh tightly, thus balancing the anti-slip effect and the mechanical fit accuracy;

[0047] A rubber sealing strip 4 is provided on the inner edge of the protective cover 102. The cross section of the rubber sealing strip 4 is trapezoidal, which is used to fit tightly against the top of the detection box 1 when closed to prevent dust from entering the lens 103 area.

[0048] The trapezoidal cross-section, wider at the top and narrower at the bottom, forms an "elastic compression seal." When closed, the sealing strip is deformed under pressure to fill the gap, achieving a dustproof rating of IP54.

[0049] Deployment and locking of main arm 201 and auxiliary arm 202;

[0050] Initial state: When the protective cover 102 is closed, the main arm 201 and the auxiliary arm 202 are folded and stored in the mounting slot 2 of the detection box 1 and the protective cover 102, and the triangular block 205 extends out of the sliding slot 203 under the action of the reset spring 206.

[0051] Deployment process: Manually rotate the protective cover 102 upwards. The main arm 201 and the auxiliary arm 202 will rotate and deploy with the hinge shaft. When the angle between the main arm 201 and the auxiliary arm 202 reaches the target angle (such as 90°), the triangular locking block 205 will align with the triangular locking groove 207 of the auxiliary arm 202. The return spring 206 will push the sliding block 204 to make the triangular locking block 205 embed into the triangular locking groove 207, forming a triangular geometric lock to prevent the arm body from rotating due to gravity.

[0052] Multi-angle adjustment: Since the sliding groove 203 and the triangular slot 207 are arranged in a ring array, different slots 207 can be selected by rotating the auxiliary arm 202 to achieve multi-angle locking within the range of 0-90°.

[0053] Folding and unlocking of main arm 201 and auxiliary arm 202

[0054] Unlocking operation: Manually rotate the auxiliary arm 202 in the folding direction. The inclined surface of the triangular block 205 slides relative to the inclined surface of the triangular slot 207. The inclined surface force compresses the return spring 206, causing the triangular block 205 to retract into the sliding groove 203 and disengage from the locked state of the slot 207.

[0055] Storage process: Continue to rotate the auxiliary arm 202, the main arm 201 and the auxiliary arm 202 fold and fit together, and finally fit into the installation slot 2. When the protective cover 102 is closed, the magnetic plates 3 attract each other, and the rubber sealing strip 4 fits tightly with the top of the detection box 1 to achieve dustproof sealing.
