Description

Technical Field

[0001] This utility model belongs to the technical field of testing devices, and specifically relates to a testing device for striking laminated glass. Background Technology

[0002] The laminated glass impact test apparatus is a device specifically designed to test the impact resistance of laminated glass. Its main function is to assess the deformation, crack propagation, and breakage of laminated glass under external force by simulating the impact force applied to the glass surface by an external object. In laminated glass impact testing, the conventional method is to conduct the test manually by striking the glass. The advantage of this method is that it does not require complex equipment; only simple tools such as a rubber mallet are needed. This is very convenient for preliminary assessment of laminated glass performance. However, its drawbacks are also obvious: it is difficult to maintain consistent force and position when striking manually, which may introduce significant deviations, leading to poor reliability and repeatability of the test results. Therefore, a new structure is proposed to address these issues. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a test device for the impact of laminated glass, so as to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a test device for striking laminated glass, comprising: a hammer assembly and a positioning assembly, wherein the hammer assembly is sleeved on the outside of a fixed shaft, and the hammer assembly includes a connecting rod for connecting the hammer head;

[0005] The fixed shaft is fixed to two sets of support plates on its left and right sides respectively. A horizontal plate is installed on the left side of the support plate. A sleeve is provided on the left side of the horizontal plate. A base is provided on the front side of the sleeve. A positioning component is installed on the front of the sleeve. The positioning component includes a positioning rod for positioning the connecting rod.

[0006] In a preferred embodiment, the two sets of support plates are of the same specifications and are arranged in a mirror symmetrical manner. A device base plate is provided below the two sets of support plates, and sliding grooves are provided at the front and rear positions of the top of the device base plate.

[0007] A sliding base is provided above the two sets of sliding grooves. A pair of mirror-symmetrical clamping plates are provided at the front and rear positions of the top of the sliding base. The laminated glass body is clamped between the two sets of clamping plates. Rubber feet are installed at the four corners of the bottom of the device base plate to increase the friction of the bottom of the device base plate and prevent the device base from shifting due to the hammer hitting the laminated glass body during the test.

[0008] In a preferred embodiment, the structures on the left side of the two sets of support plates are completely identical and arranged in a mirror symmetrical manner, and a sleeve is provided on the inner side of both the first and second horizontal plates.

[0009] In a preferred embodiment, the interval between the two sets of sleeves is 1 cm, and the interval between the two sets of sleeves matches the diameter of the connecting rod.

[0010] In a preferred embodiment, two sets of positioning grooves are vertically provided on the curved side below the connecting rod, a hammer head is welded to the bottom of the connecting rod, and the top of the connecting rod is movably connected to the outside of the fixed shaft through a sleeve.

[0011] In a preferred embodiment, a base is installed on the front side inside the sleeve, a magnetic ring is provided on the front side of the base, and a return spring is provided on the front side of the magnetic ring.

[0012] In a preferred embodiment, the sleeve has a pull button on the front and a positioning rod on the rear side of the pull button. The positioning rod extends rearward through the base, the magnetic ring, and the return spring. The length of the positioning rod is greater than the depth of the sleeve. When the hammer assembly is pulled between the front and rear sleeves, the positioning groove on the side of the connecting rod is always opposite to the back of the front sleeve. This allows the positioning rod to move rearward from inside the sleeve and engage with the positioning groove, thereby fixing the position of the hammer assembly and ensuring the consistency of the striking force and striking position.

[0013] In a preferred embodiment, the radius of the positioning rod matches the radius of the positioning groove, and a fixing plate is provided on the side of the positioning rod, with the front of the fixing plate fixed to the back of the return spring;

[0014] The front side of the fixing plate is connected to a second magnetic chuck by four sets of fixing rods. The second magnetic chuck has the same specifications as the first magnetic chuck and the opposite poles are opposite. The positioning rod is retracted into the sleeve by the attraction and fixation of the first magnetic chuck and the second magnetic chuck. The positioning rod can be moved backward from the inside of the sleeve and fitted into the positioning groove by the separation of the first magnetic chuck and the second magnetic chuck.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. By setting a hammer assembly and a positioning assembly, the hammer assembly includes a hammer head and a connecting rod, and the positioning assembly includes a positioning rod and a fixing plate. When the hammer assembly is pulled to the right to a 45-degree angle, the connecting rod is pulled to the right between the two sets of sleeves connected between the two sets of horizontal plates, so that the connecting rod is in the gap between the two sets of sleeves. Then, the positioning rod is inserted into the positioning groove, thereby fixing the position of the hammer assembly through the interlocking connection between the positioning rod and the positioning groove. Then, the pull button can be pulled forward to drive the positioning rod to disengage from the positioning groove and retract into the sleeve, so that the fixing plate on the outside of the positioning rod presses the return spring forward and the magnetic ring one and magnetic ring two are attracted and fixed, thereby retracting the positioning rod into the sleeve. At this time, the hammer assembly swings to the left and hammers the laminated glass body on the top of the device base plate. The final effect is to ensure the consistency of the striking force and position, greatly reduce the test deviation and improve the test accuracy.

[0016] 2. By setting up horizontal plates one and two, with the horizontal height of the two sets of horizontal plates one being lower than that of the two sets of horizontal plates two, and the inner structure of horizontal plates one and two being the same, the hammer assembly is pulled to the right to a 90-degree angle position, so that the connecting rod is in the gap between the two sets of sleeves fixed inside the two sets of horizontal plates two, and is fixed by the positioning rod and the positioning groove. When testing, pulling the button forward will cause the positioning rod to disengage from the inside of the positioning groove, so that the hammer assembly can swing to the left from 90 degrees and strike the laminated glass body. Therefore, the final effect is that the laminated glass body can be hit with consistent force from different heights, which significantly improves the accuracy of the test.

[0026] Please see Figures 1 to 4 A test device for striking laminated glass includes a hammer assembly 220 and a positioning assembly 300. The hammer assembly 220 is sleeved on the outside of a fixed shaft 210. The hammer assembly 220 includes a connecting rod 221 for connecting a hammer head 222.

[0027] The fixed shaft 210 is fixed to two sets of support plates 200 on the left and right sides respectively. A horizontal plate 230 is installed on the left side of the support plate 200. A sleeve 250 is provided on the left side of the horizontal plate 230. A base 251 is provided on the front side of the sleeve 250. A positioning component 300 is installed on the front of the sleeve 250. The positioning component 300 includes a positioning rod 320 for positioning the connecting rod 221.

[0028] The two sets of support plates 200 are identical in size and are arranged in a mirror symmetrical manner. Below the two sets of support plates 200, there is a device base plate 100. The top and front and rear positions of the device base plate 100 are provided with sliding grooves.

[0029] A sliding base 251 is provided above the two sets of sliding grooves. A pair of mirror-symmetrical clamping plates are provided at the front and rear positions of the top of the sliding base 251. The laminated glass body is clamped between the two sets of clamping plates. Rubber feet are installed at the four corners of the bottom of the device base plate 100 to increase the friction of the bottom of the device base plate 100 and prevent the device base 251 from shifting due to the hammer 222 hitting the laminated glass body during the test.

[0030] The two sets of support plates 200 have identical structures on the left side and are arranged in a mirror symmetrical manner. A sleeve 250 is provided on the inner side of both the first horizontal plate 230 and the second horizontal plate 240.

[0031] The interval between the two sets of sleeves 250 is 1cm, and the interval between the two sets of sleeves 250 matches the diameter of the connecting rod 221.

[0032] Two sets of positioning grooves 223 are vertically opened on the curved side below the connecting rod 221. A hammer head 222 is welded to the bottom of the connecting rod 221. The top of the connecting rod 221 is movably connected to the outside of the fixed shaft 210 through a sleeve.

[0033] A base 251 is installed on the front side inside the sleeve 250. A magnetic ring 252 is provided on the front side of the base 251, and a return spring 253 is provided on the front side of the magnetic ring 252.

[0034] The sleeve 250 has a pull button 310 on the front and a positioning rod 320 on the rear side of the pull button 310. The positioning rod 320 extends backward through the base 251, the magnetic ring 252, and the return spring 253. The length of the positioning rod 320 is greater than the depth of the sleeve 250. When the hammer assembly 220 is pulled between the front and rear sleeves 250, the positioning groove 223 on the side of the connecting rod 221 is always opposite to the back of the front sleeve 250. This allows the positioning rod 320 to move backward from inside the sleeve 250 and engage with the positioning groove 223, thereby fixing the position of the hammer assembly 220 and ensuring the consistency of the striking force and striking position.

[0035] The radius of the positioning rod 320 matches the radius of the positioning groove 223. The positioning rod 320 has a fixing plate 321 on its side, and the front of the fixing plate 321 is fixed to the back of the return spring 253.

[0036] The front side of the fixing plate 321 is connected to a magnetic ring 322 by four sets of fixing rods. The magnetic ring 322 and the magnetic ring 252 have the same specifications and opposite poles. The positioning rod 320 is retracted into the sleeve 250 by the attraction and fixation of the magnetic ring 252 and the magnetic ring 322. The positioning rod 320 can be moved backward from the sleeve 250 and engaged with the positioning groove 223 by the separation of the magnetic ring 252 and the magnetic ring 322.

[0037] Example 1: Please refer to Figures 1 to 4In actual use, four sets of rubber feet are installed at the four corners of the bottom of the device base plate 100 to increase the friction of the device base 251 and prevent it from shifting during the test. A pair of sliding grooves are opened at the front and back positions of the top of the device base plate 100. A sliding base 251 is installed above the two sets of sliding grooves. A pair of clamping plates for clamping the laminated glass body are provided above the sliding base 251. A pair of mirror-symmetrical support plates 200 are provided at the front and back positions of the top right side of the device base plate 100. A fixed shaft 210 is installed between the two sets of support plates 200. A connecting rod 221 is sleeved on the outer side of the center of the fixed shaft 210. A limiting piece is provided at the front and back positions of the connection between the connecting rod 221 and the fixed shaft 210. A hammer head 222 is provided below the connecting rod 221. The connecting rod 221 and the hammer head 222 together form a hammer assembly 220. Positioning grooves 223 are opened at the upper and lower positions of the lower side of the connecting rod 221.

[0038] Both the front and rear support plates 200 have a horizontal plate 230 on their right sides. Above each horizontal plate 230 is a horizontal plate 240, with the length of the horizontal plate 240 exceeding that of the horizontal plate 230. The inner sides of both the front horizontal plates 230 and 240 are fitted with sleeves 250. A base 251 is installed inside the front sleeve 250, with a magnetic ring 252 behind the base 251 and a return spring 253 behind the magnetic ring 252. The front sleeve 250... The interior of 0 is provided with a positioning component 300, which includes a positioning rod 320 and a fixing plate 321. The front side of the fixing plate 321 is provided with a magnetic ring 322. The front of the positioning rod 320 extends out of the sleeve 250, and the front of the positioning rod 320 is provided with a pull button 310. It should be noted that the two sets of sleeves 250 on the rear side do not contain a base 251, a magnetic ring 252, or a return spring 253, and the rear sleeves 250 do not contain the positioning component 300.

[0039] In actual operation, first pinch the hammer head 222 and pull the hammer assembly 220 to the right, raising the hammer assembly 220 to a 45-degree angle. At this time, the connecting rod 221 is between the two sets of sleeves 250 between the two sets of horizontal plates 230, and the positioning groove 223 on the upper side of the connecting rod 221 is opposite to the rear side of the front sleeve 250. Then push the pull button 310 on the front of the sleeve 250 forward, so that the pull button 310 drives the positioning rod 320 to move backward from the inside of the sleeve 250. At this time, the magnetic ring 322 disengages from the magnetic ring 252 and is fixed, and the return spring 253 returns to its original position. The positioning rod 320 is inserted into the positioning groove 223, thereby fixing the position of the hammer assembly 220. After the laminated glass body is clamped between the two sets of clamping plates, and the sliding base 251 is located on the right side of the two sets of sliding grooves, the preparation is complete.

[0040] Then, pull the button 310 forward, causing the button 310 to retract the positioning rod 320 into the sleeve 250, causing the rear side of the positioning rod 320 to disengage from the positioning groove 223. The fixing plate 321 on the side of the positioning rod 320 presses the return spring 253 forward, compressing and storing force. The magnetic ring 222 and the magnetic ring 1 are attracted and fixed, thus fixing the positioning rod 320 inside the sleeve 250. At this time, the hammer assembly 220 falls naturally and swings to the left due to its own gravity, thereby conducting a hammering test on the laminated glass body. Therefore, the final effect is that the natural fall of the hammer assembly 220 avoids human intervention during the hammering process. At the same time, the interlocking connection between the positioning rod 320 and the positioning groove 223 ensures the consistency of the hammering position and the hammering force, greatly improving the accuracy of the test results.

[0041] Example 2: Please refer to Figure 1 After the 45-degree impact test is completed, the sliding base 251 is first reset, and then the hammer head 222 is pinched again and pulled to the right to a 90-degree position, so that the hammer assembly 220 is in a horizontal position. At this time, the connecting rod 221 in the hammer assembly 220 is between the two sets of sleeves 250 connected inside the horizontal plate 240. Then, the steps in Embodiment 1 are followed to insert the positioning rod 320 backward into the positioning groove 223 below the side of the connecting rod 221, thereby fixing the position of the hammer assembly 220. During the test, the positioning rod 320 is disengaged from the positioning groove 223 by pulling the button 310 forward, so that the hammer assembly 220 falls freely and swings to the left to strike the laminated glass body, thereby completing the impact test from a 90-degree angle. Therefore, the final effect is that the laminated glass body can be tested with consistent force and consistent impact position from different heights, which greatly improves the accuracy of the test.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
