Description

Technical Field

[0001] The invention relates to the technical field of window opener chains, and in particular to a window opener chain strength testing device and a testing method based on electric window opener production. Background Art

[0002] Electric window openers are commonly used in modern buildings. They are mainly used in top-hung windows, bottom-hung windows, and some middle-hung windows, etc., which need to be opened for ventilation or smoke exhaust. It uses a motor to drive the transmission mechanism to open and close doors and windows. It has the characteristics of automation and intelligence, which extends the functions of the building. The power source of the electric window opener usually adopts a DC brushless motor or an AC induction motor, which has the advantages of small size, light weight, high efficiency, and low noise. The transmission mechanism uses a transmission method such as a gear rack, a sprocket chain, or a synchronous belt to convert the rotational motion of the motor into a linear motion or a curved motion to realize the opening and closing of doors and windows. In the production process of the chain window opener, the strength test of the chain is an important link to ensure its quality and reliability.

[0003] For example, the patent application with the prior art announcement number CN212779895U discloses a window opener chain testing device, including a base plate, two guide columns are symmetrically arranged on the base plate, springs are respectively installed at the lower ends of the guide columns, and a counterweight block is also included. Through holes are respectively opened at both ends of the counterweight block, and the guide columns pass through the through holes of the counterweight block respectively. A connecting part is also arranged in the middle part of the lower end of the counterweight block, and the connecting part includes two vertically downward connecting plates and a fixing rod, and connecting holes are respectively opened on the connecting plates, and the fixing rod passes through the two connecting plates horizontally. The utility model has a simple structure and is easy to operate. The strength of the chain of the electric window opener is tested by lifting the counterweight block that rises and falls along the guide column. The testing efficiency is high and the cost is low.

[0004] Although the above-mentioned prior art has adopted a counterweight to simulate the load when testing the strength of the window opener chain, this testing method mainly focuses on evaluating the performance of the window opener chain under pressure. However, in actual usage scenarios, the challenges faced by the window opener chain are far more than this. They not only need to withstand the downward pressure from the window or other structures, that is, the compressive performance, but also must be able to withstand the force of the chain being stretched when performing the window opening or closing action, that is, the tensile performance. The tensile performance is very important for the window opener chain because it is directly related to the durability and reliability of the chain in long-term and frequent window opening and closing operations. If the tensile performance of the chain is insufficient, then during the process of opening or closing the window, the chain may be deformed or broken due to excessive stretching, and even cause the failure of the entire window opener system. To this end, the present application proposes a window opener chain strength test device and test method based on the production of electric window openers. Summary of the invention

[0007] Preferably, the pressure assembly includes hinged seats fixedly connected to one side of the two slide seats respectively, and the interiors of the two hinged seats are rotatably connected to connecting handles fixedly connected to the straight plate, and the interiors of the hinged seats are provided with torsion springs for resetting the connecting handles.

[0008] Preferably, a sliding groove for sliding connection of a pressure plate is provided on one side of the simulation window, a sliding rod fixedly connected to the pressure plate is slidably connected inside the straight plate, and a spring for self-reset is sleeved on the outer surface of the sliding rod.

[0009] Preferably, both ends of the frame are fixedly connected with air cylinders, the tops of the two air cylinders are slidably connected with piston rods adapted thereto, and the tops of the two piston rods are fixedly connected to the bottoms of the two sliding seats, and the two air cylinders are commonly connected with an air pipe.

[0010] Preferably, the resistance assembly includes a plurality of empty grooves opened inside the mounting tube, the interiors of the plurality of empty grooves are slidably connected with resistance blocks, the mounting tube is fixedly connected to and communicated with the interior of the air pipe, the interior of the air pipe is slidably connected with a force-bearing piston rod, and the outer surface of the force-bearing piston rod is hinged with a plurality of cranks hinged to the resistance blocks.

[0011] Preferably, one end of the two slide seats is fixedly connected to a connecting plate, the tops of the two connecting plates are rotatably connected to rollers, and both ends of the rotating shaft extend to both ends of the frame and are fixedly connected to arc plates.

[0012] Preferably, a fixing seat for supporting the test window opener is fixedly connected inside the frame, and a support is fixedly connected to the bottom of the frame.

[0013] Preferably, a plurality of straight cylinders are fixedly connected inside the slide groove, a plurality of resistance sheets are rotatably connected to the bottom of the pressure plate, and a tension spring fixedly connected to the resistance sheets is fixedly connected to the bottom of the pressure plate.

[0014] Preferably, a sleeve is fixedly connected to one side of the abutment sheet, a gravity ball is slidably connected to the interior of the sleeve, and a return spring fixedly connected to the gravity ball is fixedly connected to the interior of the sleeve.

[0015] The present invention also provides a method for testing the strength of a window opener chain produced based on an electric window opener, comprising the following steps:

[0016] S1. When in use, first install the window opener chain to be tested inside the test window opener, and then install the window opener chain on one side of the simulated window and fix it;

[0017] S2, by turning on the test window opener, the window opener chain is driven to move and the simulated window is opened against the misalignment between the simulated window and the frame. When the simulated window is unfolded, it will first be restrained from moving by the force of the pressure plate. At this time, the pressure component will increase the pressure on the straight plate, so that the force applied to the simulated window will gradually increase.

[0018] S3, when the simulation window is unfolded, the pressure plate will impact the simulation window and make it vibrate;

[0019] S4. When the simulated window is fully extended, the test window opener is operated to retract the window opener chain. At this time, the resistance component will start to rotate the swivel on the surface of the mounting tube to increase the damping force, thereby applying damping to the simulated window and suppressing the tension of the window opener chain, thereby testing the tensile strength of the window opener chain.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. Through the components such as simulated window, window opener chain and pressure plate, the real use environment can be simulated. In particular, the pressure plate can block the opening of the simulated window and apply a certain resistance to it, thereby simulating the resistance of different windows in actual use. This simulation helps to more accurately test the strength and reliability of the window opener chain in actual applications. The components such as the contact plate, tension spring, sleeve and gravity ball can simulate the vibration impact caused by the wind when the window is opened. This dynamic test can more realistically reflect the force of the chain in actual use, including sudden impact and vibration, so as to ensure the stability and durability of the chain in complex environments. Through automated and mechanized design, the device can quickly complete the strength test of the window opener chain and reduce manual intervention and testing time. This helps to improve production efficiency, reduce testing costs, and make test results more accurate and reliable.

[0022] 2. By setting up a resistance component, especially the resistance of multiple resistance blocks against the swivel, precise resistance can be added to the rotation of the simulated window. This resistance simulates various load conditions that the window may encounter in actual use, so as to more accurately test the tensile strength of the window opener chain. Due to the ingenious cooperation between the resistance component and the gas cylinder, piston rod and other components, the test process can be more automated and efficient. When the simulated window is unfolded or retracted, the movement of the shaft will automatically trigger the flow of gas in the gas cylinder, thereby changing the state of the resistance component without manual intervention. This greatly improves the test efficiency and reduces the test cost. The design of the resistance component allows the resistance to be dynamically adjusted according to the test requirements. By controlling the gas pressure in the air pipe, the position of the force-bearing piston rod can be accurately adjusted, thereby controlling the contact degree and resistance of the resistance block with the swivel. This dynamic adjustment capability enables the test device to be applicable to electric window opener chains of different specifications and models. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Example 1: Please refer to Figure 1 , Figure 2 as well as Figure 4The present invention provides a technical solution: a window opener chain strength test device based on an electric window opener, comprising a frame 100 and a test window opener 105, a simulated window 102 is arranged on one side of the frame 100, a rotating shaft 103 which is rotatably connected to the frame 100 is fixedly connected to the top of the simulated window 102, a window opener chain 106 is installed inside the test window opener 105, one end of the window opener chain 106 is fixedly connected to the simulated window 102 through a connecting seat 107, the window opener chain 106 is a test piece, which can be installed inside the test window opener 105 and driven by the test window opener 105 to move and push the simulated window 102 to unfold, thereby simulating a real use environment, and a support is fixedly connected inside the frame 100. A fixing seat 104 of the support test window opener 105 is provided, and a support 101 is fixedly connected to the bottom of the frame 100. A straight plate 300 is arranged on one side of the frame 100, and a pressure plate 301 for applying resistance to the simulated window 102 is arranged at the bottom of the straight plate 300. The pressure plate 301 can block the unfolding of the simulated window 102, and apply a certain resistance to it to simulate the resistance existing in different windows during actual use. At the same time, the strength of the window opener chain 106 can be effectively tested. Both ends of the frame 100 are slidably connected with a slide seat 201, and one side of the two slide seats 201 is provided with a pressure component acting on the straight plate 300. By setting the pressure component, the window opener chain 106 can be effectively pressurized, thereby detecting its strength when in use.

[0040] For further information, see Figure 6 , Figure 7 as well as Fig. 9 The pressure assembly includes an articulated seat 202 fixedly connected to one side of the two sliding seats 201 respectively, and the interiors of the two articulated seats 202 are rotatably connected with a connecting handle 200 fixedly connected to the straight plate 300, and the interior of the articulated seat 202 is provided with a torsion spring 203 for resetting the connecting handle 200. A sliding groove 302 for sliding connection of the pressure plate 301 is provided on one side of the simulation window 102, and the interior of the straight plate 300 is slidably connected with a sliding rod 304 fixedly connected to the pressure plate 301, and the outer surface of the sliding rod 304 is sleeved with a spring 305 for its own reset. By setting the connecting handle 200, the straight plate 300 can be driven to move following the flipping of the simulation window 102, and its torsion spring 203 can gradually apply a stronger force with the unfolding angle of the simulation window 102, thereby detecting the strength of the window opener chain 106 and realizing detection of different strengths.

[0041] Among them, in order to further improve the detection strength of the window opener chain 106, the two ends of the frame 100 are fixedly connected with air cylinders 204, and the tops of the two air cylinders 204 are slidably connected with piston rods 205 adapted thereto, and the tops of the two piston rods 205 are fixedly connected to the bottoms of the two slides 201, and the two air cylinders 204 are commonly connected with an air pipe 403. The pressure of the pressure plate 301 is suppressed by simulating the flipping of the window 102. At the same time, the downward movement of the slide 201 can further yield the tilt of the connecting handle 200, thereby further applying the force of the torsion spring 203 to the connecting handle 200.

[0042] For further information, see Fig. 9 , Fig.10 as well as Fig.11 At the same time, to simulate the vibration impact caused by the wind when the window is opened, a plurality of straight cylinders 303 are fixedly connected inside the slide groove 302, and a plurality of contact pieces 306 are rotatably connected to the bottom of the pressure plate 301. A tension spring 307 fixedly connected to the contact piece 306 is fixedly connected to the bottom of the pressure plate 301, and a sleeve 308 is fixedly connected to one side of the contact piece 306. A gravity ball 309 is slidably connected inside the sleeve 308, and a reset spring 310 fixedly connected to the gravity ball 309 is fixedly connected inside the sleeve 308. As the simulated window 102 gradually unfolds, its pressure plate 301 slides on the slide groove 302. At this time, the contact piece 306 will be dislocated when it contacts the straight cylinder 303 and squeeze the tension spring 307. Then, the reset and impact of the straight cylinder 303 will cause the simulated window 102 to vibrate and put force on the window opener chain 106.

[0043] Specifically, by opening the test window opener 105, the window opener chain 106 is driven to move and resist the misalignment of the simulated window 102 and the frame 100 to open. When the simulated window 102 is unfolded, it will first be subjected to the force of the pressure plate 301 to inhibit its movement. At this time, the connecting handle 200 is subjected to the torque of the torsion spring 203 and applied to the straight plate 300 so that it applies pressure on the simulated window 102, thereby inhibiting the movement of the simulated window 102 and acting on the window opener chain 106 to test its strength. At the same time, when the simulated window 102 continues to move, it will drive the rotating shaft 103 to rotate and drive the arc plate 208 to rotate and then resist the roller 207, so that the connecting plate 206 moves downward and the transmission slide 201 moves downward to change the position of one end of the connecting handle 200, thereby increasing the connecting handle 20 0, thereby obtaining a stronger reset force on the torsion spring 203, and as the unfolding angle of the simulation window 102 gradually increases, the force applied by the pressure plate 301 to the simulation window 102 will also gradually increase. When the simulation window 102 is unfolded, the pressure plate 301 will slide on the slide groove 302, thereby driving the contact piece 306 to contact the straight cylinder 303, so that the contact piece 306 squeezes the tension spring 307 to accumulate force, and when the contact piece 306 passes over a single straight cylinder 303, it will be quickly reset by the force of the tension spring 307, thereby impacting the other straight cylinder 303 to vibrate it, and when the contact piece 306 hits the straight cylinder 303, the gravity ball 309 in its sleeve 308 will continue to approach the contact piece 306 under the action of inertia to increase its impact force.

[0044] In summary, the simulation window 102, the window opener chain 106 and the pressure plate 301 and other components can simulate the real use environment. In particular, the pressure plate 301 can block the expansion of the simulation window 102 and apply a certain resistance to it, thereby simulating the resistance of different windows in actual use. This simulation helps to more accurately test the strength and reliability of the window opener chain 106 in actual applications. The components such as the contact piece 306, the tension spring 307, the sleeve 308 and the gravity ball 309 can simulate the vibration impact caused by the wind when the window is opened. This dynamic test can more realistically reflect the stress of the chain in actual use, including sudden impact and vibration, so as to ensure the stability and durability of the chain in complex environments. Through the automated and mechanized design, the device can quickly complete the strength test of the window opener chain, reducing manual intervention and testing time. This helps to improve production efficiency, reduce testing costs, and make test results more accurate and reliable.

[0045] Example 2: Please refer to Figure 1 , Figure 2 as well as Fig.12The present invention also provides a technical solution, which is different from the technical solution of the first embodiment: a window opener chain strength testing device produced based on an electric window opener, a mounting tube 402 is arranged inside the frame 100, a swivel 401 is slidably connected to the outer surface of the mounting tube 402, a handle 400 rotatably connected to the simulated window 102 is fixedly connected at one end of the swivel 401, a resistance component is arranged inside the mounting tube 402, and the tensile strength of the window opener chain 106 can be tested by setting the resistance component.

[0046] For further information, see Figure 2 , Figure 3 as well as Fig.13 The resistance component includes a plurality of empty slots 405 opened inside the mounting tube 402, and the interiors of the plurality of empty slots 405 are slidably connected with resistance blocks 406, the mounting tube 402 is fixedly connected to the interior of the air pipe 403 and is communicated, the interior of the air pipe 403 is slidably connected with a force-bearing piston rod 404, and the outer surface of the force-bearing piston rod 404 is hinged with a plurality of cranks 407 hinged with the resistance blocks 406, one end of the two slide seats 201 is fixedly connected with a connecting plate 206, and the tops of the two connecting plates 206 are rotatably connected with rollers 207, and both ends of the rotating shaft 103 extend to both ends of the frame 100 and are fixedly connected with arc plates 208, and by arranging a plurality of resistance blocks 406 to contact with the rotating ring 401, the resistance to the rotation of the rotating ring 401 can be increased, so that the window opener chain 106 is subjected to resistance when the simulated window 102 is pulled to tilt, and the tensile strength of the window opener chain 106 is tested.

[0047] It is worth mentioning that when the rotating shaft 103 is unfolded, the rotating shaft 103 will drive the arc plate 208 to rotate and drive the connecting plate 206 to move downward, so that the piston rod 205 blows the gas in the gas cylinder 204 into the interior of the air pipe 403, so that the stressed piston rod 404 pulls the multiple cranks 407 to tilt and retract the multiple resistance blocks 406 to eliminate the interference with the swivel 401.

[0048] Specifically, when the simulated window 102 is fully unfolded, the test window opener 105 is operated to retract the window opener chain 106. At this time, the rotation of the rotating shaft 103 will drive the connecting plate 206 to reset, so that the piston end of the piston rod 205 moves upward in the air cylinder 204, and the air in the air pipe 403 is pumped into the air cylinder 204. At this time, the stressed piston rod 404 in the air pipe 403 will move under the force, thereby pulling multiple cranks 407 gradually perpendicular to them and unfolding multiple resistance blocks 406, so that they come into contact with the swivel 401 to increase its damping force, thereby applying damping to the simulated window 102 and suppressing the tension of the window opener chain 106, thereby testing the tensile strength of the window opener chain 106.

[0049] In summary, by setting the resistance assembly, especially the conflict between the multiple resistance blocks 406 and the rotating ring 401, accurate resistance can be added to the rotation of the simulated window 102. This resistance simulates various load conditions that the window may encounter in actual use, so as to more accurately test the tensile strength of the window opener chain 106. Due to the ingenious cooperation between the resistance assembly and the components such as the gas cylinder 204 and the piston rod 205, the test process can be more automated and efficient. When the simulated window 102 is unfolded or retracted, the movement of the rotating shaft 103 will automatically trigger the flow of gas in the gas cylinder 204, thereby changing the state of the resistance assembly without manual intervention. This greatly improves the test efficiency and reduces the test cost. The design of the resistance assembly allows the resistance size to be dynamically adjusted according to the test requirements. By controlling the gas pressure in the trachea, the position of the stressed piston rod 404 can be accurately adjusted, thereby controlling the contact degree and resistance size of the resistance block 406 and the rotating ring 401. This dynamic adjustment capability enables the test device to be applicable to electric window opener chains of different specifications and models.

[0050] Example 3: Please refer to Figures 1 to 14 The present invention also provides a technical solution, which is different from the technical solution of the first embodiment: a method for testing the strength of a window opener chain produced by an electric window opener, comprising the following steps:

[0051] S1. When in use, first install the window opener chain 106 to be tested inside the test window opener 105, then place the test window opener 105 on the top of the fixing seat 104 for fixing, and then install the connecting seat 107 on one side of the simulation window 102 for fixing;

[0052] S2, by opening the test window opener 105, the window opener chain 106 is driven to move and resist the misalignment of the simulated window 102 and the frame 100 to open. When the simulated window 102 is unfolded, it will first be subjected to the force of the pressure plate 301 to inhibit its movement. At this time, the connecting handle 200 is subjected to the torque of the torsion spring 203 and applied to the straight plate 300 so that it applies pressure on the simulated window 102, thereby inhibiting the movement of the simulated window 102 and acting on the window opener chain 106 to test its strength. At the same time, when the simulated window 102 continues to move, it will drive the rotating shaft 103 to rotate and drive the arc plate 208 to rotate and then resist the roller 207, so that the connecting plate 206 moves downward and the transmission slide 201 moves downward to change the position of one end of the connecting handle 200, thereby increasing the inclination angle of the connecting handle 200 to obtain a stronger reset force on the torsion spring 203, and as the unfolding angle of the simulated window 102 gradually increases, the force applied by the pressure plate 301 to the simulated window 102 will also gradually increase;

[0053] S3. When the simulation window 102 is unfolded, the pressure plate 301 will slide on the slide groove 302, thereby driving the contact piece 306 to contact the straight tube 303, so that the contact piece 306 squeezes the tension spring 307 to store force, and when the contact piece 306 passes over a single straight tube 303, it will be quickly reset by the force of the tension spring 307, thereby impacting the other straight tube 303 to make it vibrate, and when the contact piece 306 hits the straight tube 303, the gravity ball 309 in the sleeve 308 will continue to approach the contact piece 306 under the action of inertia to increase the impact force;

[0054] S4. When the simulated window 102 is fully unfolded, the test window opener 105 is operated to retract the window opener chain 106. At this time, the rotation of the shaft 103 will drive the connecting plate 206 to reset, so that the piston end of the piston rod 205 moves upward in the air cylinder 204, and the air in the air pipe 403 is pumped into the air cylinder 204. At this time, the stressed piston rod 404 in the air pipe 403 will move under the force, thereby pulling multiple cranks 407 gradually perpendicular to it and unfolding multiple resistance blocks 406, so that it contacts the swivel 401 to increase its damping force, thereby applying damping to the simulated window 102 and suppressing the tension of the window opener chain 106, thereby testing the tensile strength of the window opener chain 106.

[0055] In summary, the performance of the window opener chain 106 under various load and resistance conditions can be comprehensively evaluated. By simulating the unfolding and retracting process of the window 102, as well as the applied dynamic resistance and vibration impact, the tensile strength, durability and stability of the chain can be accurately tested. By simulating the mutual cooperation of the components such as the window 102, the pressure plate 301, and the resistance component, various load and resistance conditions that the window may encounter in actual use can be accurately simulated. This simulation helps to ensure that the test results are consistent with the actual situation and improve the accuracy and reliability of the test.
