Description

Technical Field

[0001] This utility model belongs to the technical field of testing devices, specifically relating to a guardrail glass impact testing device. Background Technology

[0002] The impact strength of glass is usually tested using the falling ball impact test. The glass is placed in a designated position, and a ball of a specified weight is dropped freely from a specified height to impact the glass. The impact strength of the glass is then determined by observing whether it breaks.

[0003] In related existing technologies, such as Chinese Patent No. CN219284842U, a device for testing the impact resistance of architectural glass is disclosed. This device includes a limiting tube with an outer ring fixed at its top and an inner groove on the inner side of its bottom. A bottom tube is also provided at the bottom of the limiting tube. A clamping mechanism is installed on the bottom tube, and a placement mechanism is installed at the top of the limiting tube. In this design, the placement mechanism is used to place a freely falling iron ball. The placement mechanism is secured to the outer ring at the top of the limiting tube via the inner groove of the top tube. The iron ball is placed in the middle of the placement plate. By pulling a frame, the frame moves the frame plate outwards, causing the placement plate to move inside the frame, detaching the iron ball from the bottom of the limiting tube and allowing it to fall freely onto the glass for impact resistance testing. The device is easy to assemble and carry, and the drop height of the iron ball can be adjusted according to the needs of the impact test. It is typically low-cost and easy to produce and use.

[0004] However, in practical use, since the length of the limiting tube is fixed—meaning that the distance between the top tube and the bottom tube cannot be adjusted, and the distance between the falling ball and the glass surface cannot be adjusted—multiple limiting tubes of different lengths are required for glass strength testing to conduct multiple impact tests with varying impact intensities. The use of multiple limiting tubes increases equipment costs and is inconvenient for carrying and use. In summary, the above solution has a limited detection range and applicability for a single limiting tube, making it unsuitable for practical use. Utility Model Content

[0005] The present invention aims to provide a guardrail glass impact testing device to solve the problem of the limited applicability of existing testing devices mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a guardrail glass impact detection device, comprising...

[0007] The bottom cylinder has a positioning component installed on its outer side;

[0008] The limiting cylinder is detachably connected to the bottom cylinder. The limiting cylinder and the bottom cylinder are arranged coaxially. The side wall of the limiting cylinder has a notch.

[0009] The outer sleeve is slidably fitted onto the limiting sleeve. Inside the outer sleeve, there is a fixed protrusion that slides with the notch.

[0010] A limiting component is installed on the outer sleeve and is used to limit the position of the outer sleeve relative to the limiting cylinder;

[0011] The control plate is slidably inserted into the outer sleeve, passing through the notch and extending into the limiting sleeve.

[0012] The principle and effects of this technical solution:

[0013] 1. By setting notches, protrusions, and limiting components, the position of the outer sleeve relative to the limiting sleeve can be adjusted, and the height of the control plate can also be changed accordingly. In this way, the height of the test ball placed on the control plate can be adjusted within the limiting sleeve, so that a single limiting sleeve can be used to test glass for impact strength of different intensities, thereby improving the testing range and expanding the applicability.

[0014] 2. A control plate is inserted into the limiting cylinder so that the test ball can be placed on the control plate for positioning. By pulling the control plate to remove it from the limiting cylinder, the ball can fall freely under its own weight, thereby testing the strength of the glass.

[0015] 3. The notch facilitates the removal of gas and reduces the impact of air resistance inside the limiting cylinder on the sphere.

[0016] The present invention is further configured such that: the outer wall of the outer sleeve has a protrusion, the control plate is slidably inserted into the protrusion, and the side of the control plate away from the limiting cylinder has a control block, the control block being magnetic.

[0017] The principle and effect of this technical solution: By setting the protrusion, the sliding stability of the control block relative to the outer sleeve is strengthened, and the control block is made magnetic, which can ensure that the control block can maintain its stability with the outer sleeve by magnetic attraction when no external force is applied.

[0018] The present invention is further configured such that: the side wall of the limiting cylinder is provided with a plurality of limiting holes spaced apart along the axial direction; the limiting component includes a limiting rod and a pull ring; the limiting rod is slidably inserted into the outer sleeve; and the end of the limiting rod can extend into the limiting hole; the pull ring is fixed to the side of the limiting rod away from the limiting cylinder.

[0019] The principle and effect of this technical solution: By inserting and fitting the limiting rod into the limiting hole, the limiting rod can connect and position the outer sleeve and the limiting cylinder, ensuring the position of the outer sleeve on the limiting cylinder. The pull ring facilitates the user's control of the position of the limiting rod.

[0020] The present invention is further configured such that: the limiting component also includes a fixed cylinder, a pressure plate and a spring, the fixed cylinder is fixed to the side wall of the outer sleeve, the limiting rod is slidably inserted into the fixed cylinder, the pressure plate is fixed to the limiting rod and slidably fitted inside the fixed cylinder, and the spring is installed inside the fixed cylinder and located on the side of the pressure plate away from the outer sleeve.

[0021] The principle and effect of this technical solution: Through the rebound force of the spring in the fixed cylinder, the pressure plate can be spontaneously driven to approach the limiting cylinder, that is, the limiting rod is controlled to approach the limiting hole, thereby ensuring the stability of the fit between the limiting rod and the limiting hole.

[0022] The present invention is further configured such that: the positioning component includes a horizontal plate, a vertical rod and a suction cup; multiple horizontal plates are arranged at intervals along the circumference on the outer wall of the bottom cylinder; a vertical rod is fixed to the bottom surface of the horizontal plate on the side away from the bottom cylinder; and the suction cup is fixed to the bottom surface of the vertical rod.

[0023] The principle and effect of this technical solution: By setting up suction cups and vertical rods, after the suction cups are fixed on the glass, the vertical rods can support the horizontal plates. Multiple horizontal plates jointly support and limit the bottom cylinder, so that the bottom cylinder can be stably placed on the glass.

[0024] The present invention is further configured such that: the positioning component includes a slider, a top plate, a clamping plate, a first control unit, and a second control unit; there are an even number of horizontal plates, and at least one pair of opposing horizontal plates have a groove on their top surface, with the slider slidingly fitted inside the groove; the top plate is fixed to the slider, and the top plate slides against the top surface of the horizontal plate; the clamping plate has an inverted U-shaped cross section, and the horizontal plate slides against the inner side of the clamping plate; the first control unit is installed on the horizontal plate and is used to control the position of the clamping plate relative to the outer sleeve; the second control unit is installed on the top plate and is used to control the distance between the top surface of the clamping plate and the horizontal plate.

[0025] The principle and effect of this technical solution: By setting a pair of opposing clamps, the glass can be clamped on both sides. The distance between the two clamps can be controlled by two first control parts to clamp glass of different sizes. The height of the clamps can be controlled by the second control part to ensure that the clamps do not interfere with the operation of the suction cup. At the same time, the length of the clamps extending to the bottom of the horizontal plate can be adjusted according to the thickness of the glass.

[0026] The present invention is further configured such that: the first control unit includes a first control head and a first screw, the first screw is rotatably installed in the slide groove, the slider is threadedly fitted on the first screw, and one end of the first screw extends to the outside of the cross plate and is connected to the first control head.

[0027] The principle and effect of this technical solution: By setting the first screw and the slider to be threaded together, the rotation of the first screw can drive the slider to slide in the groove. That is, the rotation of the first screw driven by the first control head can drive the clamping plate to move closer to or away from the limiting cylinder. And through the clamping of the clamping plates on both sides, it can achieve the clamping effect on glass of different widths.

[0028] The present invention is further configured such that: the second control unit includes a second control head and a second screw, the second screw is rotatably mounted on the top plate and threadedly inserted into the clamping plate, and the second control head is fixed to the top surface of the second screw.

[0029] The principle and effect of this technical solution: The screw insertion of the second screw into the clamping plate and the sliding fit between the clamping plate and the horizontal plate restrict the rotation of the clamping plate. The second control head controls the rotation of the second screw, which can drive the clamping plate to rise and fall relative to the second screw. This allows the bottom edge height of the clamping plate to rise and fall, so that the bottom edge height of the second clamping plate can be adjusted according to the thickness of the glass to be tested. Furthermore, the bottom edge of the clamping plate can be stored in a way that prevents the suction cup from adhering to the glass. Attached Figure Description

[0047] Example:

[0048] As attached Figure 1-6 As shown, this utility model discloses a guardrail glass impact detection device, including a base cylinder 110, a limiting cylinder 210, an outer sleeve 310, a limiting component, and a control plate 410. A positioning component is installed on the outer side of the base cylinder 110. The positioning component includes a horizontal plate 610, a vertical rod 620, and a suction cup 630. It also includes a slider 710, a top plate 720, a clamping plate 730, a first control unit, and a second control unit.

[0049] The outer wall of the bottom cylinder 110 is provided with an even number of horizontal plates 610 arranged circumferentially (4 are used as an example in this scheme, but it can also be 2, 6 or 8). A vertical rod 620 is fixed to the bottom surface of the horizontal plate 610 away from the bottom cylinder 110. A suction cup 630 is fixed to the bottom surface of the vertical rod 620. The glass can be adsorbed by the suction cup 630 so that the bottom cylinder 110 abuts against the glass surface. When the suction cup 630 firmly adheres to the glass, the bottom cylinder 110 just abuts against the glass surface.

[0050] At least one pair of opposing horizontal plates 610 have a sliding groove 611 on their top surface, and at most two pairs are provided with a 90-degree angle between them. A slider 710 is slidably fitted inside the sliding groove 611. A top plate 720 is fixed on the slider 710 and slides against the top surface of the horizontal plate 610. The cross section of the clamping plate 730 is inverted U-shaped, and the horizontal plate 610 is slidably fitted inside the clamping plate 730. A first control unit is installed on the horizontal plate 610 and is used to control the position of the clamping plate 730 relative to the outer sleeve 310. A second control unit is installed on the top plate 720 and is used to control the distance between the top surface of the clamping plate 730 and the horizontal plate 610. On a horizontal plate 610, a clamping plate 730 is located between a suction cup 630 and a limiting cylinder 210. When using it on smaller glass, the bottom cylinder 110 is placed against the glass, and then the distance between the clamping plates 730 and 730 is adjusted according to the size of the glass. The height of the bottom edge of the clamping plate 730 is adjusted according to the thickness of the glass so that the clamping plate 730 can fully contact the glass.

[0051] The first control unit includes a first control head 810 and a first screw 820. The first screw 820 is rotatably mounted in the slide groove 611. The slider 710 is threadedly fitted onto the first screw 820. One end of the first screw 820 extends out of the horizontal plate 610 and is connected to the first control head 810. The second control unit includes a second control head 910 and a second screw 920. The second screw 920 is rotatably mounted on the top plate 720 and is threadedly inserted into the clamping plate 730. The second control head 910 is fixed to the top surface of the second screw 920.

[0052] The limiting cylinder 210 and the bottom cylinder 110 are detachably connected (by means of insertion, threaded connection, etc.). The limiting cylinder 210 and the bottom cylinder 110 are arranged coaxially. The side wall of the limiting cylinder 210 has a notch 211, which penetrates the side wall and axial direction of the limiting cylinder 210. The outer sleeve 310 is slidably fitted onto the limiting cylinder 210. A protrusion 320 is fixed inside the outer sleeve 310. The protrusion 320 is slidably fitted with the notch 211. The control plate 410 is slidably inserted onto the outer sleeve 310. The control plate 410 passes through the notch 211 and extends into the limiting cylinder 210. The outer wall of the outer sleeve 310 has a protrusion 311. The control plate 410 is slidably inserted into the protrusion 311. The side of the control plate 410 away from the limiting cylinder 210 has a control block 420. The control block 420 is magnetic. The protrusion 311 is a metal component.

[0053] The side wall of the limiting cylinder 210 is provided with a plurality of limiting holes 212 spaced apart along the axial direction. The limiting assembly includes a limiting rod 510 and a pull ring 520. The limiting rod 510 is slidably inserted into the outer sleeve 310, and the end of the limiting rod 510 can extend into the limiting hole 212. The pull ring 520 is fixed to the side of the limiting rod 510 away from the limiting cylinder 210.

[0054] The limiting assembly also includes a fixed cylinder 530, a pressure plate 540, and a spring 550. The fixed cylinder 530 is fixed to the side wall of the outer sleeve 310. The limiting rod 510 is slidably inserted into the fixed cylinder 530. The pressure plate 540 is fixed to the limiting rod 510 and is slidably fitted inside the fixed cylinder 530. The spring 550 is installed inside the fixed cylinder 530 and is located on the side of the pressure plate 540 away from the outer sleeve 310.

[0055] In use, the ball 120 used for testing can abut against the control plate 410 placed inside the limiting cylinder 210. Pulling out the control plate 410 will release the restriction on the ball 120. When adjusting the position of the outer sleeve 310, the user controls the pull rings 520 on both sides with both hands to make the limiting rod 510 leave the limiting hole 212. Then, the position of the outer sleeve 310 is adjusted by moving it up and down. After the adjustment is in place, the pull rings 520 are released, and then the limiting rod 510 is moved up and down. After the limiting rod 510 corresponds with the limiting hole 212, the limiting rod 510 automatically enters the limiting hole 212. The outer wall of the limiting cylinder 210 is marked with graduations.

[0056] Among them, insert and sliding insert are mating bodies with holes, the cross section of the shaft or rod matches the hole, and the shaft or rod can slide relative to the hole. Threaded insert is a hole with threads, the shaft or rod is threaded, and the shaft or rod is connected to the mating body by screwing. Detachable installation can be by bolt thread connection or bolt and nut connection, etc., depending on what can be actually achieved.

[0057] This device is portable and can quickly locate and inspect glass, making it easy to use.
