[0002] RV, also known as "home on wheels", has the functions of both "house" and "car", but its attribute is still a car. It is a movable type of vehicle with basic facilities necessary for home. Since RVs are often parked outdoors in different areas, safety is extremely important. Therefore, when RVs are produced, the glass, doors and frames need to be tested for strength and pressure resistance. Only after passing the test can they be put into use. Generally speaking, the tempered glass of RVs is either interlayered or not. Specifically, the side windows and rear windows of RVs are tempered glass, and the front windshield of RVs is laminated glass. In the strength test of the tempered glass of RVs, a detection device is needed.

[0012] A method for using a RV glass compressive strength testing device comprises the following steps: S1. First, place the RV tempered glass between two clamps, start the electric push rods, and the output ends of the two electric push rods push the corresponding clamps to move toward the tempered glass to achieve clamping and fixing of the tempered glass.

[0013] S2. After completing the clamping of the RV glass, start the electric cylinder, and the output end of the electric cylinder pushes the mounting frame toward the shell. After the impact rod moves into place, the mounting frame drives the clamping piece at one end of the impact rod to move into the shell, and the first spring is squeezed and contracted under force. During the movement of the mounting frame, the pressing block fixed on the mounting frame is squeezed on the movable sleeve, so that the groove key on the inner wall of the movable sleeve slides in the first guide groove inside the guide sleeve, so that the guide sleeve drives the rotating sleeve to complete a 90-degree rotation. At this time, the pressing rod on the rotating sleeve is squeezed on the inclined surface at the corresponding extrusion rod end, so that the extrusion rod pushes the corresponding second limit block to move to the middle of the shell and corresponds to the clamping piece. After the impact rod moves into place, the output end of the electric cylinder shrinks quickly, and the mounting frame releases the push of the electric cylinder and moves back under the elastic reset of the first spring. At this time, the limit pin at one end of the impact rod will be clamped in the limit groove on the corresponding second limit block, completing the locking of the impact rod position.

[0014] S3. When the mounting bracket moves toward the shell, the sixth spring is squeezed and contracted, so that the sixth spring pushes the connecting sleeve to move, so that the push rod in the second guide groove moves to the lower part of the second guide groove, and the push rod descends and moves out of the corresponding limit groove, so that the limit pin at one end of the impact rod will be stuck in the limit groove on the corresponding second limit block.

[0015] S4. When the mounting frame is released from the squeeze with the output end of the electric cylinder, the sixth spring elastically resets and pushes the mounting frame to continue moving. After the mounting frame moves into place, the pull rod at one end of the connecting sleeve is pulled to move, so that the top rod in the second guide groove on the connecting sleeve moves to the high point of the second guide groove. At this time, the top rod moves up and enters the corresponding limit groove, so that the top rod squeezes and pushes the limit pin engaged in the limit groove to move up, so that the limit pin releases the limit on the limit groove. At this time, the impact rod releases the limit and quickly hits the glass under the elastic reset of the first spring to detect the glass tipping. When the pressing block on the mounting frame squeezes the movable sleeve again, the previous second limit block is reset. At the same time, the adjacent second limit block moves to the middle of the shell to limit the impact rod. In this way, the glass impact test of the impact rod with different strengths is carried out reciprocatingly in sequence.

[0016] S5. When the impact rod hits the glass surface, the impact will produce glass fragments and the splashing of fragments. There is a certain danger in the observation of the operator. When the output end of the electric cylinder is reset, the U-shaped sliding frame fixed to the output end of the electric cylinder slides toward the inside of the protective cover, so that the two ends of the U-shaped sliding frame are pressed against the corresponding connecting rods. At this time, the connecting rod drives the rack at one end to engage with the gear on the surface of the rotating shaft, so that the rotating shaft drives the protective door panel to flip 90 degrees. At this time, the two symmetrical protective door panels are in a closed state to prevent the splashing debris from causing harm to personnel. When the electric cylinder drives the U-shaped sliding frame to move away from the protective door panel, the connecting rod is released from the squeezing of the U-shaped sliding frame, and the elastic reset of the second reset spring pushes the connecting rod to move. After moving into place, the first limit ring limits the movement of the connecting rod. At this time, the rack at the end of the connecting rod is engaged with the gear on the rotating shaft again, so that the two protective door panels are flipped 90 degrees. The two protective door panels are in an open state, which is convenient for personnel to observe the impact of the glass.

[0017] S6. When the U-shaped sliding frame moves to reset and closes the two protective door panels, the U-shaped sliding frame below is pressed on the corresponding second push rod, causing the L-shaped pressure rod hinged at one end of the second push rod to deflect with the middle part as the axis. At this time, one end of the L-shaped pressure rod is pressed on the corresponding baffle plate, causing the baffle plate to flip over. The two symmetrical baffle plates are in an open state, and the debris falls into the collection box under the chassis for collection.

[0018] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, by setting components such as the detection part, the force adjustment mechanism and the manual adjustment component, the impact force can be automatically adjusted with the cooperation of the detection part and the force adjustment mechanism, so that the impact rod can perform impact tests on tempered glass under different forces, and thus multiple groups of relevant data can be obtained, thereby reducing experimental costs and improving data accuracy. In addition, through the setting of the manual adjustment component, the locking position of the impact rod is the same each time, so that impact tests with the same force can be achieved, thereby improving the scope of application of the device.

[0019] In the present invention, through the arrangement of the electric push rod and the protection mechanism, before the impact rod is reset to impact the glass, the two protection door panels are in a closed state to prevent flying debris from causing harm to personnel. When the impact rod moves away from the protection door panels, the two protection door panels are in an open state to facilitate personnel to observe the impact of the glass.

[0020] In the present invention, through the arrangement of the electric push rod, the protection mechanism and the unloading mechanism, when the impact rod hits the glass, one end of the L-shaped pressure rod will be pressed on the corresponding baffle plate to flip the baffle plate. The two baffle plates are in an open state, and the debris falls into the collection box under the chassis, which is convenient for the later cleaning of the debris.

After the mounting bracket 302 moves into place, the pull rod 5031 at one end of the connecting sleeve 5032 is pulled to move, so that the push rod 5037 in the second guide groove 5036 on the connecting sleeve 5032 moves to the lower part of the second guide groove 5036. 036, at this time, the push rod 5037 moves up and enters the corresponding limit groove 50121, so that the push rod 5037 squeezes and pushes the limit pin 401 connected in the limit groove 50121 to move up, so that the limit pin 401 releases the limit on the limit groove 50121, and at this time, the impact rod 301 is released from the limit, and under the elastic reset of the first spring 305, it quickly hits the glass to detect the glass tipping, and when the pressing block 5027 on the mounting frame 302 squeezes and pushes the movable sleeve 5025 again, the previous second limit block 5012 is reset, and at the same time, the adjacent second limit block 5012 moves to the middle part of the shell 5011 to limit the impact rod 301. In this way, the glass impact test of the impact rod 301 with different forces is carried out reciprocatingly in sequence, and multiple sets of relevant data can be obtained, thereby reducing the experimental cost and improving the accuracy of the data.

[0030] In this embodiment, Figure 4 , Figure 7 and Figure 8 As shown, the surface of the mounting rod 5022 is provided with an oblique groove 50221 that matches the pressing rod 5023, the surface of the pressing rod 5023 is sleeved with a fourth spring 50222, and one end of the fourth spring 50222 is fixedly connected to the surface of the pressing rod 5023, and the other end of the fourth spring 50222 is fixedly connected to the inner wall of the rotating sleeve 5021, and two threaded grooves 50224 are provided on the mounting rod 5022, and a threaded rod 50223 is threadedly installed between the rotating sleeve 5021 and the corresponding threaded groove 50224.

[0031] When it is necessary to manually adjust the impact force of the impact rod 301, first unscrew the threaded rod 50223 from the corresponding threaded groove 50224, and then push the installation rod 5022 to move into the rotating sleeve 5021. At this time, the pressing rod 5023 releases the extrusion of the inclined surface inside the inclined groove 50221, and under the elastic reset of the fourth spring 50222, the pressing rod 5023 shrinks to the inside of the inclined groove 50221. When the rotating sleeve 5021 rotates, the pressing rod 5023 will not contact the corresponding extrusion rod 5013, and therefore will not automatically push the second limit block 5012 to move.

[0032] In this embodiment, Figure 1 , Figure 2 , Figure 8 and Fig. 9 As shown, the manual adjustment component 6 includes a first push rod 601 fixedly mounted on the mounting frame 302; a limit sleeve 602 slidably mounted on the housing 5011, and one side of the limit sleeve 602 is an open structure, so that when the limit pin 401 moves into place, it will not be interfered with during the reset movement; a tapered rod 603 movably mounted on the limit sleeve 602. It should be added here that the bottom of one end of the first push rod 601 and the top of the tapered rod 603 are both set to be tapered, so that the first push rod 601 can squeeze the tapered rod 603 up and down when it moves. Movement allows the bottom of the conical rod 603 to push the limiting pin 401 on the impact rod 301 to contract, so as to realize the ejection of the impact rod 301; and a first return spring 604 is sleeved on the conical rod 603, and one end of the first return spring 604 is fixedly connected to the top wall of the conical rod 603, and the other end of the first return spring 604 is fixedly connected to the top of the limiting sleeve 602; an adjusting screw 605 is threadedly mounted on the housing 5011, and one end of the adjusting screw 605 is rotatably mounted inside one side of the limiting sleeve 602.

[0033] One end of the adjusting screw rod 605 is rotatably mounted inside one side of the limiting sleeve 602 through a bearing, so that the adjusting screw rod 605 can rotate freely on the limiting sleeve 602. When the adjusting screw rod 605 rotates, the limiting sleeve 602 can be pushed to move, thereby changing the position of the limiting sleeve 602 and realizing locking of the impact rod 301 at different positions. When it is not necessary to change the impact force of the impact rod 301, firstly, the threaded rod 50223 is unscrewed from the corresponding threaded groove 50224, and then the installation rod 5022 is pushed to move into the rotating sleeve 5021. At this time, the pressing rod 5023 releases the inclined groove 50224. The pressing rod 5023 is retracted into the inclined groove 50221 under the elastic reset of the fourth spring 50222 due to the extrusion of the internal inclined surface of 0221. When the rotating sleeve 5021 rotates, the pressing rod 5023 will not contact the corresponding extrusion rod 5013, and thus will not automatically push the second limit block 5012 to move. Then, by rotating the adjusting screw 605, the adjusting screw 605 drives the limit sleeve 602 to move to the corresponding position. At this time, when the electric cylinder 303 pushes the impact rod 301 to lock, the locking position is the same each time, so that the impact test of the same force is achieved, thereby improving the application range of the device.

[0034] In this embodiment, Figure 3 , Fig.11 , Fig.12 and Fig.13 As shown, the protection mechanism 7 includes two protection door plates 701 arranged on the front side of the protection cover 2; a rotating shaft 702 fixedly mounted on the protection door plates 701, and the upper and lower ends of the rotating shaft 702 are rotatably mounted on the top wall of the protection cover 2 and the surface of the chassis 1 respectively; and a gear 703 fixedly mounted on the rotating shaft 702. It should be supplemented that two gears 703 are symmetrically arranged on the rotating shaft 702 to improve the stability of the protection door plates 701 when opening and closing; a rack 704 meshing with the gear 703; a connecting rod 705 fixedly mounted on the rack 704; a U-shaped sliding frame 706 that pushes the connecting rod 705 to move, and the middle part of the U-shaped sliding frame 706 is fixedly mounted on the output end of the adjacent electric cylinder 303. It should be noted that both sides of the U-shaped sliding frame 706 are slidably installed on the inner wall of the protective cover 2, and the end of the U-shaped sliding frame 706 is mounted on the corresponding connecting rod 705 to facilitate pushing the connecting rod 705 to move; one end of the connecting rod 705 is sleeved with a positioning sleeve 707, and one side of the positioning sleeve 707 is fixedly installed on the inner wall of the protective cover 2, and the surface of one end of the connecting rod 705 is sleeved with a second return spring 708, and one end of the second return spring 708 is fixedly connected to the surface of the positioning sleeve 707, and the other end of the second return spring 708 is fixedly connected to the end of the connecting rod 705, and a first limiting ring 709 is fixedly installed in the middle of the connecting rod 705, and a feeding mechanism 8 is arranged between the inside of the protective cover 2 and the chassis 1.

[0035] In addition, when the impact rod 301 hits the glass surface, the impact will produce glass fragments and the fragments will splash. In the observation of the operator, there is a certain danger. When the output end of the electric cylinder 303 is reset, the U-shaped sliding frame 706 fixed to the output end of the electric cylinder 303 slides toward the inside of the protective cover 2, so that the two ends of the U-shaped sliding frame 706 are pressed against the corresponding connecting rod 705. At this time, the connecting rod 705 drives the rack 704 at one end to engage with the gear 703 on the surface of the rotating shaft 702, so that the rotating shaft 702 drives the protective door plate 701 to flip 90 degrees, so that before the impact rod 301 hits the glass, the two symmetrical protective door plates 701 It is in a closed state to prevent flying debris from causing harm to personnel, and when the electric cylinder 303 drives the U-shaped sliding frame 706 to move away from the protective door panel 701, the connecting rod 705 is released from the squeezing of the U-shaped sliding frame 706, and under the elastic reset of the second reset spring 708, the connecting rod 705 is pushed to move. After moving into place, the first limiting ring 709 limits the movement of the connecting rod 705. At this time, the rack 704 at the end of the connecting rod 705 is engaged with the gear 703 on the rotating shaft 702 again, so that the two protective door panels 701 are flipped 90 degrees, and the two protective door panels 701 are in an open state, so that personnel can observe the impact of the glass.

[0036] In this embodiment, Figure 3 , Fig.11 and Fig.14 , the unloading mechanism 8 includes two baffle plates 801 symmetrically rotatably mounted on the chassis 1. It should be supplemented here that the two ends of the baffle plates 801 are rotatably mounted on the chassis 1 through torsion springs. When the baffle plates 801 are not squeezed by external force, the two baffle plates 801 are in a closed state; an L-shaped pressure rod 802 is mounted on the baffle plate 801, and the middle part of the L-shaped pressure rod 802 is rotatably mounted on the inner wall of the protective cover 2; a waist-shaped groove 803 is opened on the L-shaped pressure rod 802; a second push rod 804 is hingedly mounted in the waist-shaped groove 803, and one end of the second push rod 804 passes through the protective cover 2 and is mounted on the surface of the adjacent U-shaped sliding frame 706; the surface of one end of the second push rod 804 is covered with a third return spring 805, and one end of the third return spring 805 is fixedly connected to the outer wall of the protective cover 2, the other end of the third return spring 805 is fixedly connected to the end of the second push rod 804, and the middle part of the second push rod 804 is fixedly connected with a second limiting ring 806.

[0037] When the U-shaped sliding frame 706 moves to reset, the two protective door panels 701 are closed, and the impact rod 301 hits the glass, the U-shaped sliding frame 706 below is squeezed on the corresponding second push rod 804, causing the L-shaped pressure rod 802 hinged at one end of the second push rod 804 to deflect around the middle part as the axis. At this time, one end of the L-shaped pressure rod 802 is squeezed on the corresponding baffle plate 801, causing the baffle plate 801 to flip over. The two symmetrical baffle plates 801 are in an open state, and debris falls into the collection box below the chassis 1, which is convenient for cleaning the debris.

[0038] In this embodiment, Figures 1 to 14 As shown, a method for using a RV glass compressive strength testing device comprises the following steps: S1. First, place the RV tempered glass between two clamps 202, start the electric push rods 201, and the output ends of the two electric push rods 201 push the corresponding clamps 202 to move toward the tempered glass to achieve clamping and fixing of the tempered glass.

[0039] S2. After the RV glass is clamped, the electric cylinder 303 is started, and the output end of the electric cylinder 303 pushes the mounting frame 302 toward the housing 5011. After the impact rod 301 moves into place, the mounting frame 302 drives the clamping member 4 at one end of the impact rod 301 to move into the housing 5011, and the first spring 305 is squeezed and contracted. When the mounting frame 302 moves, the pressing block 5027 fixed on the mounting frame 302 is squeezed on the movable sleeve 5025, so that the groove key 50251 on the inner wall of the movable sleeve 5025 slides in the first guide groove 50241 inside the guide sleeve 5024, so that the guide sleeve 5024 drives the rotating sleeve 5021 After completing a 90-degree rotation, the pressing rod 5023 on the rotating sleeve 5021 is squeezed on the inclined surface at the end of the corresponding extrusion rod 5013, so that the extrusion rod 5013 pushes the corresponding second limit block 5012 to move to the middle of the shell 5011 and corresponds to the clamping part 4. After the impact rod 301 moves into place, the output end of the electric cylinder 303 shrinks rapidly, and the mounting frame 302 releases the push of the electric cylinder 303 and moves back under the elastic reset of the first spring 305. At this time, the limit pin 401 at one end of the impact rod 301 will be clamped in the limit groove 50121 on the corresponding second limit block 5012, completing the locking of the position of the impact rod 301.

[0040] S3. When the mounting bracket 302 moves toward the shell 5011, the sixth spring 5033 is squeezed and contracted, so that the sixth spring 5033 pushes the connecting sleeve 5032 to move, and the top rod 5037 in the second guide groove 5036 moves to the lower part of the second guide groove 5036. The top rod 5037 descends and moves out of the corresponding limit groove 50121, so that the limit pin 401 at one end of the impact rod 301 will be stuck in the limit groove 50121 on the corresponding second limit block 5012.

[0041] S4. When the mounting frame 302 is released from the squeeze between the output end of the electric cylinder 303, the sixth spring 5033 is elastically reset to push the mounting frame 302 to continue to move. After the mounting frame 302 is moved into place, the pull rod 5031 at one end of the connecting sleeve 5032 is pulled to move, so that the push rod 5037 in the second guide groove 5036 on the connecting sleeve 5032 moves to the height of the second guide groove 5036. At this time, the push rod 5037 moves up and enters the corresponding limit groove 50121, so that the push rod 5037 squeezes and pushes the limit pin 40121 that is clamped in the limit groove 50121. 1 moves upward, so that the limiting pin 401 releases the limiting of the limiting groove 50121. At this time, the impact rod 301 releases the limiting, and quickly impacts the glass under the elastic reset of the first spring 305 to detect the glass tipping. When the pressing block 5027 on the mounting frame 302 pushes the movable sleeve 5025 again, the previous second limiting block 5012 is reset, and the adjacent second limiting block 5012 moves to the middle of the shell 5011 to limit the impact rod 301. In this way, the glass impact test of the impact rod 301 with different strengths is carried out reciprocatingly in sequence.

[0042] S5. When the impact rod 301 hits the glass surface, the impact will produce glass fragments and the fragments will splash. In the observation of the operator, there is a certain danger. When the output end of the electric cylinder 303 is reset, the U-shaped sliding frame 706 fixed to the output end of the electric cylinder 303 slides toward the inside of the protective cover 2, so that the two ends of the U-shaped sliding frame 706 are pressed against the corresponding connecting rod 705. At this time, the connecting rod 705 drives the rack 704 at one end to engage with the gear 703 on the surface of the rotating shaft 702, so that the rotating shaft 702 drives the protective door plate 701 to flip 90 degrees. At this time, the two symmetrical protective door plates 701 are in a closed state. To prevent flying debris from causing harm to personnel, when the electric cylinder 303 drives the U-shaped sliding frame 706 to move away from the protective door panel 701, the connecting rod 705 is released from the squeezing of the U-shaped sliding frame 706, and under the elastic reset of the second reset spring 708, the connecting rod 705 is pushed to move. After moving into place, the first limiting ring 709 limits the movement of the connecting rod 705. At this time, the rack 704 at the end of the connecting rod 705 is engaged with the gear 703 on the rotating shaft 702 again, so that the two protective door panels 701 are flipped 90 degrees, and the two protective door panels 701 are in an open state, which is convenient for personnel to observe the impact of the glass.

[0043] S6. When the U-shaped sliding frame 706 moves to reset and closes the two protective door panels 701, the U-shaped sliding frame 706 at the bottom is pressed on the corresponding second push rod 804, causing the L-shaped pressure rod 802 hinged at one end of the second push rod 804 to deflect around the middle part as the axis. At this time, one end of the L-shaped pressure rod 802 is pressed on the corresponding baffle plate 801, causing the baffle plate 801 to flip over. The two symmetrical baffle plates 801 are in an open state, and the debris falls into the collection box under the chassis 1 for collection.

At this time, the limit pin (401) at one end of the impact rod (301) is clamped in the limit groove (50121) on the corresponding second limit block (5012), thereby completing the locking of the position of the impact rod (301); S3, when the mounting frame (302) moves toward the housing (5011), the sixth spring (5033) is squeezed and contracted, so that the sixth spring (5033) pushes the connecting sleeve (5032) to move, so that the push rod (5037) in the second guide groove (5036) moves to the lower part of the second guide groove (5036), and the push rod (5037) descends and moves out of the corresponding limiting groove (50121), so that the limiting pin (401) at one end of the impact rod (301) is clamped in the limiting groove (50121) on the corresponding second limiting block (5012); S4. When the mounting frame (302) is released from the squeezing of the output end of the electric cylinder (303), the sixth spring (5033) is elastically reset to push the mounting frame (302) to continue to move. After the mounting frame (302) is moved into place, the pull rod (5031) at one end of the connecting sleeve (5032) is pulled to move, so that the push rod (5037) in the second guide groove (5036) on the connecting sleeve (5032) moves to the top of the second guide groove (5036). At this time, the push rod (5037) moves upward and enters the corresponding limit groove (50121), so that the push rod (5037) squeezes and pushes the limit pin engaged in the limit groove (50121). (401) moves upward, so that the limiting pin (401) releases the limiting of the limiting groove (50121), and at this time, the impact rod (301) releases the limiting, and quickly impacts the glass under the elastic reset of the first spring (305) to detect the glass tipping, and when the pressing block (5027) on the mounting frame (302) pushes the movable sleeve (5025) again, the previous second limiting block (5012) is reset, and at the same time, the adjacent second limiting block (5012) moves to the middle of the shell (5011) to limit the impact rod (301), and in this way, the glass impact test of the impact rod (301) with different strengths is carried out in sequence; S5. When the impact rod (301) impacts the glass surface, the impact will generate glass fragments, and the fragments will splash. In the observation of the operator, there is a certain danger. When the output end of the electric cylinder (303) is reset, the U-shaped sliding frame (706) fixed to the output end of the electric cylinder (303) slides toward the inside of the protective cover (2), so that the two ends of the U-shaped sliding frame (706) are pressed against the corresponding connecting rod (705). At this time, the connecting rod (705) drives the rack (704) at one end to mesh with the gear (703) on the surface of the rotating shaft (702), so that the rotating shaft (702) drives the protective door plate (701) to flip 90 degrees. At this time, the two symmetrical protective door plates (701) are in a closed state, avoiding To prevent splashing debris from causing harm to personnel, when the electric cylinder (303) drives the U-shaped sliding frame (706) to move away from the protective door plate (701), the connecting rod (705) is released from the squeezing of the U-shaped sliding frame (706), and the connecting rod (705) is pushed to move under the elastic reset of the second reset spring (708). After moving into position, the first limiting ring (709) limits the movement of the connecting rod (705). At this time, the rack (704) at the end of the connecting rod (705) is again meshed with the gear (703) on the rotating shaft (702), so that the two protective door plates (701) are flipped 90 degrees, and the two protective door plates (701) are in an open state, which is convenient for personnel to observe the impact of the glass; S6. When the U-shaped sliding frame (706) moves to reset and the two protective door panels (701) are closed, the lower U-shaped sliding frame (706) presses on the corresponding second push rod (804), causing the L-shaped pressure rod (802) hinged at one end of the second push rod (804) to deflect around the middle as the axis. At this time, one end of the L-shaped pressure rod (802) presses on the corresponding baffle plate (801), causing the baffle plate (801) to flip over. The two symmetrical baffle plates (801) are in an open state, and the debris falls into the collection box below the chassis (1) for collection of the debris.
