When explosion-proof panels are produced, they need to be subjected to strength testing.

[0003] A Chinese utility model patent with announcement number CN209707282U discloses a door panel strength testing device for explosion-proof door production, including a load-bearing base plate, a servo motor is provided on one side of the upper end of the load-bearing base plate, a gear plate is connected to the upper end of the servo motor, a bearing is connected to one side of the servo motor and the upper end of the load-bearing base plate, a turntable is connected to the upper end of the bearing, gear grooves are provided around the lower side of the turntable, and fixed seats are fixedly connected to both sides of the upper end of the turntable. A triangular bracket is fixedly connected to the upper end of the No. 2 slider, and the triangular bracket can move on the No. 1 slide groove through the slider. At the same time, the servo motor drives the gear plate to rotate, thereby driving the turntable to rotate. Therefore, the hammer head can perform multi-point strength detection on the explosion-proof door production door panel clamped on the turntable, and the detected pressure is transmitted to the central processing unit by the pressure sensor and then displayed on the display screen.

[0004] Although the above-mentioned prior art has a simple and practical structure and is easy to operate, which greatly improves the practicality of the device, when the explosion-proof plate is tested, if the explosion-proof plate is not strong enough or the pressure is too high, the explosion-proof plate will be broken, and the fragments will fly around, which may easily injure the surrounding workers and pose a safety hazard. Utility Model Content

[0005] In order to solve the technical problem that when the explosion-proof panel is tested, if the strength of the explosion-proof panel is not enough or the pressure is too large, the explosion-proof panel will be broken, and the fragments will fly around, which may easily injure the surrounding staff and pose a safety hazard, the utility model provides a testing device for the explosion-proof panel.

[0006] The utility model is implemented by the following technical scheme: a test device for explosion-proof panels, comprising a base, an upper surface of the base is fixedly connected to a test platform, both sides of the test platform are provided with fixing components for fixing the explosion-proof panels, the top of the base is fixedly connected to a bracket, the top of the bracket is provided with a detection mechanism for strength detection of the explosion-proof panels, and a protective mechanism is provided inside the base for preventing the explosion-proof panels from breaking during detection and protecting the staff.

[0008] Through the above technical solution, the two-way screw is rotated to make the movable block drive the protective box to move inward, and the test bench is sealed when closed to prevent the fragments from causing harm to surrounding personnel when the explosion-proof plate breaks, thereby improving safety.

[0009] As a further improvement of the above scheme, the detection mechanism includes a mounting plate fixedly installed on the top of the bracket and a first slide groove opened on the inner side of the bracket, a hydraulic cylinder is fixedly installed in the middle of the mounting plate, an output end of the hydraulic cylinder is fixedly connected to a fixed seat, support rods sliding inside the first slide groove are fixedly connected on both sides of the fixed seat, and a detection head is fixedly connected to the bottom of the fixed seat.

[0010] Through the above technical solution, the explosion-proof plate is pressure tested by the hydraulic cylinder and the detection head, and the use of the support rod improves the stability when pressing down.

[0011] As a further improvement of the above solution, the fixing assembly includes fixing plates fixedly connected to both sides of the detection platform, and the top of the fixing plate is threadedly connected with a fastening screw.

[0012] Through the above technical solution, the structure is simple, the operation is convenient, and the testing speed of the explosion-proof panel is accelerated.

[0013] As a further improvement of the above solution, a toothed plate fixedly connected to the support rod is penetrated through the top of the base, and gears are transmission-connected to both ends of the bidirectional screw rod, and the gears are meshingly connected to the toothed plate.

[0014] As a further improvement of the above solution, the protection box and the detection platform are arranged correspondingly, and a hole corresponding to the detection head is opened on the top of the protection box.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The utility model improves stability when pressing down by sliding the support rod in the first slide groove. When the support rod slides downward in the first slide groove, it drives the tooth plate to move downward, so that the gear drives the two-way screw to rotate. When the two-way screw rotates, the movable block drives the protection box to close inwardly through the second slide groove. When the protection box is closed, the seal of the test bench is protected. When the explosion-proof plate is pressed down during the explosion-proof plate test, the design enables the protection box to protect the test bench to prevent the explosion-proof plate from breaking and injuring people, thereby improving safety.

[0026] By rotating the bidirectional screw rod 12, the movable block 15 drives the protection box 16 to move inward, and the test bench 2 is sealed when closed to prevent the fragments from causing harm to surrounding workers when the explosion-proof plate breaks, thereby improving safety.

[0027] Please combine Figure 1The detection mechanism includes a mounting plate 4 fixedly mounted on the top of the bracket 3 and a first slide groove 6 opened on the inner side of the bracket 3. A hydraulic cylinder 5 is fixedly mounted in the middle of the mounting plate 4. The output end of the hydraulic cylinder 5 is fixedly connected to a fixed seat 7. Both sides of the fixed seat 7 are fixedly connected to support rods 8 sliding inside the first slide groove 6, and a detection head 9 is fixedly connected to the bottom of the fixed seat 7.

[0028] The explosion-proof plate is pressure-tested by means of the hydraulic cylinder 5 and the detection head 9, and the use of the support rod 8 improves the stability during downward pressure.

[0029] Please combine Figure 2 The fixing assembly includes a fixing plate 10 fixedly connected to both sides of the detection platform 2, and a fastening screw 11 is threadedly connected to the top of the fixing plate 10.

[0030] The structure is simple and the operation is convenient, which can speed up the testing of explosion-proof panels.

[0031] Please combine Figure 3 A toothed plate 13 fixedly connected to the support rod 8 is penetrated through the top of the base 1 , and gears 14 are transmission-connected to both ends of the bidirectional screw rod 12 , and the gears 14 are meshedly connected to the toothed plate 13 .
