Description

Technical Field

[0001] The invention relates to the technical field of curtain wall opening window detection, in particular to an existing curtain wall opening window safety and firmness detection instrument. Background Art

[0002] Sliding windows are a commonly used type of curtain wall opening window. Their parallel opening and closing characteristics can open a larger opening area, so they are widely installed on curtain walls. In order to improve the safety of sliding windows, the installed sliding windows are generally subject to appearance inspection and glass strength inspection. The appearance inspection is generally a manual inspection to see if there are scratches, cracks and other defects on the glass surface. However, the glass strength inspection requires a certain load to be applied to the glass to observe whether the glass is deformed or damaged, so relevant testing instruments are required to assist manual inspection. At present, there are two main ways to test the strength of glass. One is to gradually apply static load to the glass of the sliding window and record the compressive strength of the glass. The other is to quickly impact the sliding window glass, such as using an air cannon to impact the glass, to evaluate the impact strength of the glass. However, most testing instruments are not easy to combine the above two testing methods and multiple testing items such as glass thermal insulation performance testing on one instrument. Testing different test items separately is not conducive to improving the efficiency of sliding window glass safety testing. In addition, unqualified glass is prone to cracking and chipping during strength testing. Most testing instruments lack a protective structure to prevent broken glass from falling. Summary of the invention

[0003] The purpose of the present invention is to provide a safety and firmness detector for an existing curtain wall opening window to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions: An existing curtain wall opening window safety and firmness detector, comprising: A bracket, the bracket comprising a pipe fitting 1, both ends of the pipe fitting 1 being slidably mounted with fixing components; The detection mechanism comprises a shaft rod rotatably connected to the pipe fitting, a V-shaped tube is fixed to one end of the shaft rod, a round hole is provided through the corner of the V-shaped tube, interception components are arranged at both ends of the V-shaped tube, a glass ball is placed inside the V-shaped tube, and a partition is slidably inserted near the corner of the V-shaped tube; A protective cover is arranged on the outside of the window glass, and a shaped frame is fixed on the outside of the protective cover; The adjusting mechanism is arranged on the outside of the shaft rod and can adjust the protective cover to a position close to the window glass. The adjusting mechanism includes a supporting tube fixed to the pipe fitting, and the outer side of the supporting tube is transmission-connected with a connecting seat, and one end of the connecting seat is equipped with a connecting rod three that can pull the yoke.

[0005] Furthermore, a connecting plate fixed to the V-shaped pipe is fixed to the outer side of the shaft rod, and a motor capable of driving the shaft rod to rotate is fixed to the outer side of the first pipe fitting.

[0006] Furthermore, the fixing assembly includes: The second pipe fitting is slidably sleeved on the end of the first pipe fitting, and the second pipe fitting and the first pipe fitting are fixed by bolts; A cylinder is fixed to one end of the second pipe fitting, and a suction cup is fixed to the output end of the cylinder.

[0007] Furthermore, a temperature sensor is installed and fixed inside the protective cover. The C-shaped frame includes a first connecting rod fixed to the protective cover, and one end of the first connecting rod is screwed with a second connecting rod.

[0008] Furthermore, the second connecting rod is screwed with a third connecting rod. A fixing block is fixed to the top of the connecting seat by bolts, and the third connecting rod is detachably fixed between the connecting seat and the fixing block.

[0009] Furthermore, a fourth connecting rod is installed on the outer side of the second connecting rod, and a square column movably inserted into the second connecting rod is fixed to one end of the fourth connecting rod.

[0010] Furthermore, the intercepting assembly includes a motor fixed to the V-shaped pipe. An eccentric wheel is fixed to the output end of the motor, and an arc-shaped rubber block is fixed to one side of the eccentric wheel.

[0011] Furthermore, the V-shaped pipe includes two guiding pipes arranged obliquely and communicating with each other. A sealing cover is screwed to one end of the guiding pipe. An arc-shaped hole for the eccentric wheel to rotate is formed through one end of the guiding pipe, and the top surface of the arc-shaped rubber block is an inclined surface.

[0012] Furthermore, the support pipe is rotatably sleeved on the outer side of the shaft rod, and a threaded pipe is screwed to the outer side of the support pipe.

[0013] Furthermore, the threaded pipe is rotatably connected to the connecting seat, and a rotating ring is sleeved and fixed on the outer side of the threaded pipe.

[0014] Compared with the prior art, the beneficial effects of the present invention are: A shaft rod is rotatably connected to the outside of the first pipe fitting. One end of the shaft rod is fixed with a V-shaped pipe, which is composed of two guide pipes arranged obliquely and communicating with each other. A round hole is provided at the connection position of the two guide pipes. By placing a glass ball on the top of one guide pipe, the interception component releases the glass ball, and the glass ball can quickly impact the glass of the casement window at the round hole along the inclined guide pipe. After the impact, the glass ball rolls along the other guide pipe to the bottom of the guide pipe. Then the shaft rod rotates 180 degrees, so that the glass ball located at the bottom of the guide pipe is transferred to the top of the guide pipe again. The interception component releases the glass ball again, and the glass ball can quickly impact the glass again. In this way, the glass ball can continuously and quickly impact the glass, which is convenient for detecting whether the glass is broken or damaged after multiple instantaneous impacts, and then evaluating the impact resistance of the glass.

[0015] By inserting the partition into the guide pipe at the lower position, the two guide pipes are not connected. Then, a plurality of glass balls are placed inside the guide pipe at the upper position. The motor drives the eccentric wheel to rotate, and the arc-shaped rubber block on one side of the eccentric wheel gradually squeezes and approaches the glass ball closest to the top of the guide pipe. By setting the surface of the arc-shaped rubber block as an inclined plane, as the eccentric wheel rotates towards the position of the glass ball with the eccentric block, the thicker area on the arc-shaped rubber block gradually moves to the outside of the glass ball, so that a plurality of glass balls are simultaneously squeezed towards the window glass, realizing the gradual application of extrusion force on the glass, which is convenient for evaluating the compressive strength of the glass under static load extrusion.

[0016] By removing the sealing caps at both ends of the V-shaped pipe, one end of the V-shaped pipe is connected to the pipe for conveying hot air from the outside, and the hot air will be conveyed to the round hole position of the V-shaped pipe through the V-shaped pipe, so that the glass at the round hole position is in a high-temperature environment. At the same time, a protective cover is installed by pasting it on the outdoor side of the glass. The temperature sensor inside the protective cover can detect the outdoor temperature at the heating position of the glass. During a period of hot air heating for the glass, if the temperature inside the protective cover does not increase significantly, it indicates that the heat insulation effect of the glass meets the requirements. If the temperature inside the protective cover increases significantly, it indicates that the heat insulation effect of the glass does not meet the requirements. Thus, it is realized that through the V-shaped pipe, glass balls and other related components, the impact resistance of the casement window glass under rapid impact force, the extrusion resistance under static load and the heat insulation performance of the glass can be detected simultaneously, which is beneficial to improving the efficiency of the safety detection of the casement window glass.

[0017] By fixing a U-shaped frame that can be sleeved outside the window glass on the outside of the protective cover, the U-shaped frame is installed on the shaft rod through the connecting rod three, or is held by the user through the connecting rod four, so that the protective cover can move synchronously with the circular hole detection position of the V-shaped tube when the V-shaped tube performs a firmness test on the glass. Thus, the protective cover is always arranged on the outdoor side of the glass detection position. Even if the unqualified glass breaks and sheds slag during the detection process, the glass slag can fall inside the protective cover. Glue can be coated on the inner side of the open mouth of the protective cover, which can make the fallen fragments adhere to the protective cover, effectively preventing the glass slag inside from falling when the protective cover is removed, and improving the safety of the glass strength detection to a certain extent.

[0018] By abutting the circular hole position of the V-shaped tube against different positions on the indoor side of the glass, it is convenient for the detector to perform strength detection on different areas of the glass. The detection results at multiple locations are more representative, which is beneficial to improving the accuracy of the strength detection results of the casement window glass.

Detailed implementation mode

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Example 1, please refer to Figure 1 - Figure 8 In the embodiment of the present invention, a safety and firmness detector for an opening window of an existing curtain wall includes a bracket 100. The bracket 100 includes a first pipe fitting 110. Both ends of the first pipe fitting 110 are slidably connected with a fixing assembly 120. A detection mechanism 200 is arranged in the middle of the first pipe fitting 110. The detection mechanism 200 includes a shaft rod 210 rotatably connected with the first pipe fitting 110. One end of the shaft rod 210 is fixed with a V-shaped pipe 220. A round hole is formed through the corner of the V-shaped pipe 220. Intercepting assemblies 230 are arranged at both ends of the V-shaped pipe 220. A glass ball 240 is placed inside the V-shaped pipe 220. A partition board 250 is slidably inserted near the corner of the V-shaped pipe 220. The round hole position of the V-shaped pipe 220 is arranged against the indoor side of the window glass. A protective cover 300 is arranged on the outdoor side of the window glass. A U-shaped frame is fixed on the outer side of the protective cover 300. An adjusting mechanism 400 capable of adjusting the protective cover 300 to be against the outdoor side of the window glass is arranged on the outer side of the shaft rod 210. The adjusting mechanism 400 includes a support pipe 410 fixed to the first pipe fitting 110. A connecting seat 430 is drivingly connected to the outer side of the support pipe 410. One end of the connecting seat 430 is provided with a third connecting rod 440 capable of pulling the U-shaped frame.

[0023] Specifically, by installing a V-shaped tube 220 on the indoor side of the casement window glass and placing a glass ball 240 inside the V-shaped tube 220, as the V-shaped tube 220 rotates, the glass ball 240 can continuously circulate and impact the glass at the corner round holes of the V-shaped tube 220, realizing the detection of the impact resistance of the glass after multiple rapid impacts. By blocking the V-shaped tube 220 with a partition 250, multiple glass balls 240 can only move inside one guiding tube of the V-shaped tube 220. The eccentric wheel 232 of the interception assembly 230 drives the arc-shaped rubber block 233 to gradually squeeze the topmost glass ball 240, so that multiple glass balls 240 gradually squeeze the glass at the round holes, realizing the detection of the compressive strength of the glass under continuous static load. By using a device that generates hot air outside to convey hot air to one end of the stationary V-shaped tube 220, the hot air can continuously blow onto the glass, making the indoor side of the glass in a high-temperature environment, and observing whether the temperature inside the protective cover 300 on the outdoor side of the glass is abnormal to indirectly judge the heat insulation performance of the glass. Thus, multiple safety detection items of the casement window glass can be completed using one detection instrument, which is beneficial to improving the efficiency of the safety detection of the casement window glass. At the same time, the protective cover 300 on the outdoor side of the glass can protect the outside of the glass and prevent glass debris from falling when unqualified glass is detected.

[0024] As Figure 3 and Figure 4 shown, in this embodiment, a connecting plate 211 fixed to the V-shaped tube 220 is fixed on the outer side of the shaft rod 210, and a motor 111 capable of driving the shaft rod 210 to rotate is fixed on the outer side of the pipe fitting one 110. Referring to Figure 3 , when it is necessary to rotate the V-shaped tube 220 to make the glass ball 240 circulate and roll to the corner of the V-shaped tube 220 to impact the glass, the motor 111 drives the shaft rod 210 to rotate, and the shaft rod 210 drives the V-shaped tube 220 to rotate through the connecting plate 211.

[0025] In this embodiment, before the V-shaped tube 220 rotates, the connecting rod three 440 on the adjusting mechanism 400 needs to be disassembled from the adjusting mechanism 400 to leave enough rotation space for the later rotation of the V-shaped tube 220. At the same time, the connecting rod four 500 can be inserted and installed on the C-shaped frame of the protective cover 300, and the protective cover 300 can be protected on the outdoor side of the glass by the user holding the connecting rod four 500. The connecting rod four 500 is arranged obliquely and will not interfere with the rotation of the V-shaped tube 220. A space is left between the pipe fitting one 110 and the end of the V-shaped tube 220 to prevent the pipe fitting one 110 from interfering with the rotation of the V-shaped tube 220.

[0026] As Figure 7As shown, in this embodiment, a temperature sensor 330 is fixedly installed inside the protective cover 300. The temperature sensor 330 is used to detect the temperature outside the glass. The temperature sensor 330 is a component of the prior art, and its specific working principle will not be elaborated here. The C-shaped frame includes a connecting rod one 310 fixed to the protective cover 300, and one end of the connecting rod one 310 is screwed with a connecting rod two 320.

[0027] In this embodiment, when the protective cover 300 is placed outdoors, first push the window of the horizontal sliding window outwards horizontally. Regarding the prior art of the horizontal sliding position of the horizontal sliding window, it will not be elaborated here. Then move the connecting rod one 310 with the protective cover 300 from the space between the window and the window frame to the outside, and then screw and install the connecting rod two 320 on the joint one 311 at the end of the connecting rod one 310.

[0028] In this embodiment, a connecting rod four 500 is installed on the outside of the connecting rod two 320. One end of the connecting rod four 500 is fixed with a square column 510 that is movably inserted into the connecting rod two 320. When the connecting rod four 500 needs to be installed on the connecting rod two 320, insert the square column 510 at one end of the connecting rod four 500 into the square hole 321 of the connecting rod two 320, so that the connecting rod four 500 and the connecting rod two 320 are inserted and fixed together. The circular block on the square column 510 restricts the depth of the square column 510 inserted into the square hole 321 to prevent over-insertion.

[0029] As Figure 1 、 Figure 7 and Figure 8 As shown, in this embodiment, the connecting rod two 320 is screwed with the connecting rod three 440. The top of the connecting seat 430 is fixed with a fixing block 431 by bolts, and the connecting rod three 440 is detachably fixed between the connecting seat 430 and the fixing block 431.

[0030] In this embodiment, when the connecting rod two 320 needs to be installed on the adjusting mechanism 400, pass the connecting rod three 440 through the pipe fitting one 110 and then through the connecting seat 430. The joint two 441 at the end of the connecting rod three 440 is screwed with the connecting rod two 320. Finally, fix the fixing block 431 on the connecting seat 430 with bolts. The fixing block 431 presses and fixes the connecting rod three 440 on the connecting seat 430. At this time, the connecting seat 430 can be moved back and forth along the support pipe 410 by rotating the threaded pipe 420 forward and backward, so as to adjust the protective cover 300 to the position where its opening abuts against the glass. It should be noted that only when the V-shaped pipe 220 is performing static load detection or heat insulation detection, the connecting rod two 320 of the protective cover 300 is installed on the adjusting mechanism 400. During this process, the V-shaped pipe 220 is in a static state and will not rotate outside the glass.

[0031] As Figure 5 andFigure 6 As shown, in this embodiment, the interception component 230 includes a motor 231 fixed to the V-shaped tube 220. An eccentric wheel 232 is fixed to the output end of the motor 231. An arc-shaped rubber block 233 is fixed to one side of the eccentric wheel 232. The top surface of the arc-shaped rubber block 233 is an inclined surface. The V-shaped tube 220 includes two guiding tubes that are inclined and interconnected. An arc-shaped hole 222 for the eccentric wheel 232 to rotate is formed through one end of the guiding tube.

[0032] In this embodiment, when the glass ball 240 at one end of the guiding tube close to the sealing cover 221 rotates towards the high position along with the guiding tube, the motor 231 drives the eccentric wheel 232 to rotate, so that the long end of the eccentric wheel 232 moves into the guiding tube, thereby preventing the glass ball 240 from rolling along the guiding tube before reaching the highest position. After the glass ball 240 rotates to the highest position along with the guiding tube, the motor 231 drives the eccentric wheel 232 to continue rotating, so that the long end of the eccentric wheel 232 leaves the glass ball 240. Without the shielding of the eccentric wheel 232, the glass ball 240 can automatically fall along the guiding tube and hit the glass.

[0033] In this embodiment, one end of the guiding tube is screwed and connected to the sealing cover 221. When it is necessary to take out the glass ball 240 inside the guiding tube, the sealing cover 221 can be screwed and disassembled, and then the guiding tube is rotated to the position where the opening faces downward, which is convenient for the glass ball 240 to automatically leave the guiding tube. Among them, a connecting tube is connected and installed on the sealing cover 221, and the connecting tube is convenient for connecting with the pipeline for conveying hot air outside.

[0034] As Figure 8 shown, in this embodiment, the support tube 410 is rotatably sleeved on the outside of the shaft rod 210, so that the rotation of the shaft rod 210 will not drive the support tube 410 to rotate. The support tube 410 can enable the shaft rod 210 to rotate stably on the pipe fitting one 110. A threaded tube 420 is screwed and connected to the outside of the support tube 410. The threaded tube 420 is rotatably connected to the connecting seat 430. A rotating ring is sleeved and fixed on the outside of the threaded tube 420. The user rotates the rotating ring to make the threaded tube 420 screw and move on the outside of the support tube 410, so as to drive the connecting seat 430 to move by the threaded tube 420, and the connecting seat 430 drives the connecting rod three 440 to move, which is convenient for adjusting the position of the protective cover 300.

[0035] Embodiment 2, on the basis of Embodiment 1, in order to enable the detector to be installed and fixed on the curtain wall.

[0036] As Figure 1 shown, in this embodiment, the fixing component 120 includes a pipe fitting two 121 slidably sleeved on the end of the pipe fitting one 110. The pipe fitting two 121 is fixed to the pipe fitting one 110 by bolts. A cylinder 122 is fixed to one end of the pipe fitting two 121. A suction cup 123 is fixed to the output end of the cylinder 122.

[0037] In this embodiment, two pipe fittings II 121 are pulled out along the pipe fitting I 110 by an appropriate length, and then bolts are used to pass through the corresponding jacks on the pipe fitting I 110 and the pipe fitting II 121, so as to fix the adjusted pipe fitting II 121 on the pipe fitting I 110. Finally, the output end of the air cylinder 122 extends so that the suction cup 123 can contact the curtain wall, and then the suction cup 123 in the prior art evacuates the air to adsorb and fix on the curtain wall, so as to fix the whole detector on the curtain wall through the fixing component 120.

[0038] In the present invention, a rubber sleeve can be sleeved outside the glass ball 240 to prevent the glass ball 240 from damaging the surface of the glass. At the same time, the glass ball 240 of the present application can also be made of other materials. The greater the material density, the greater the force of the ball hitting the glass. The specific material can be selected according to needs and will not be elaborated here in detail.
