[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] This utility model provides a technical solution: such as Figures 1 to 6 As shown in this embodiment, a pressure testing device for building inspection includes a test chamber 1. A first hydraulic cylinder 2 is installed at the top of the test chamber 1, and a lower pressure plate 3 is installed at the output end of the first hydraulic cylinder 2. A second hydraulic cylinder 4 is installed at the back of the test chamber 1. A lower pressure groove 6 is opened inside the test chamber 1. A load-bearing plate 5 is provided at the upper end of the lower pressure groove 6. The output end of the second hydraulic cylinder 4 is connected to the rear end of the load-bearing plate 5. A collection box 7 is provided at the lower end of the lower pressure groove 6. A locking groove 8 is provided at the front end of the collection box 7. Side baffles 9 are installed on both sides of the front end of the test chamber 1. A protective plate 10 is slidably connected between the two sets of side baffles 9. An observation window 11 is provided in the middle of the protective plate 10. A horizontal pull handle 15 is connected to the bottom end of the protective plate 10 through a locking component.

[0024] By installing a sliding protective plate 10 at the front end of the test chamber 1 and side baffles 9 on both sides of the front end of the test chamber 1, the two sets of side baffles 9 can limit the front and rear of the protective plate 10, allowing the protective plate 10 to slide and close the front end of the test chamber 1. Then, the locking component fixes the position of the protective plate 10, thereby effectively preventing the protective plate 10 from opening accidentally when it is impacted, and effectively improving the safety of the equipment during use. Furthermore, by installing a detachable collection box 7 in the pressure groove 6, the collection box 7 can effectively collect the debris generated during the experiment, making it convenient to clean up the debris.

[0025] In other embodiments, the locking assembly includes two sets of vertical cylinders 12 fixed to the bottom of the test chamber 1. Each set of vertical cylinders 12 is provided with a movable ring 13. Each set of movable rings 13 is fixed with a locking rod 14. The front ends of the two sets of locking rods 14 are connected to a horizontal pull handle 15. Each set of vertical cylinders 12 is provided with a return spring 16 on its inner wall. Each set of return springs 16 is wrapped around the outside of the locking rod 14. The bottom of the test chamber 1 is provided with two sets of positioning holes 17. The rear ends of the two sets of locking rods 14 are inserted into the two sets of positioning holes 17. The upper end of the test chamber 1 is provided with two sets of locking sleeves 18.

[0026] When it is necessary to open the protective plate 10, the horizontal pull handle 15 can be pulled forward to allow the two sets of locking rods 14 to slide along the two sets of vertical cylinders 12, causing the external movable rings 13 to slide. When the two sets of locking rods 14 are completely disengaged from the two sets of positioning holes 17, the horizontal pull handle 15 can be pushed upward to allow the protective plate 10 to slide upward and open. When the protective plate 10 moves the two sets of locking rods 14 to the two sets of locking sleeves 18, the horizontal pull handle 15 can be pushed backward to move the two sets of locking rods 14 backward, allowing them to insert into the two sets of locking sleeves 18. This limits the movement of the protective plate 10, facilitating the opening of the protective plate 10. Materials are placed into or removed from test chamber 1, and then the above operation is repeated in reverse. The horizontal pull handle 15 drives the two sets of locking rods 14 away from the two sets of locking sleeves 18. Then the horizontal pull handle 15 is pulled down, so that the protective plate 10 moves the two sets of locking rods 14 to the two sets of positioning holes 17. Then the tension on the horizontal pull handle 15 can be released, so that the two sets of return springs 16 release their elasticity and push the two sets of movable rings 13 to move backward, so that the two sets of locking rods 14 can be inserted into the two sets of positioning holes 17 at the bottom of test chamber 1, thereby ensuring the stability of the protective plate 10 and preventing the protective plate 10 from being opened accidentally by impact.

[0027] In other embodiments, the viewing window 11 is made of high-strength transparent polycarbonate material;

[0028] This design effectively improves the impact resistance of the observation window 11 and allows users to directly observe the test process from the outside.

[0029] In other embodiments, the collection box 7 is slidably connected to the bottom of the pressure groove 6, and the inner wall of the collection box 7 is polished.

[0030] The collection box 7 can be pulled out and put in quickly through the slot 8, making it easy to clean the debris inside the collection box 7.

[0031] In other embodiments, the diameter of the locking rod 14 is the same as the inner diameter of the positioning hole 17 and the locking sleeve 18;

[0032] With this design, when the ends of the two sets of locking rods 14 are inserted into the two sets of positioning holes 17 or the two sets of locking sleeves 18, the two sets of locking rods 14 can form a stable limiting effect on the protective plate 10.

[0033] In other embodiments, the outer wall of the movable ring 13 is fully fitted with the inner wall of the vertical cylinder 12, and the movable ring 13 and the vertical cylinder 12 form a sliding connection;

[0034] With this design, when the movable ring 13 drives the locking rod 14 to slide back and forth along the inside of the vertical cylinder 12, it can effectively prevent the movable ring 13 from shaking during the movement, thereby ensuring that the two sets of movable rings 13 can drive the two sets of locking rods 14 to move smoothly.

[0035] In other embodiments, the two ends of the return spring 16 are respectively connected to the outer wall of the movable ring 13 and the inner wall of the vertical cylinder 12, and the movable ring 13 is elastically connected to the inner wall of the vertical cylinder 12 through the return spring 16;

[0036] This design allows the return springs 16 inside the two sets of vertical cylinders 12 to continuously apply elastic force toward the protective plate 10 to the movable rings 13, enabling the two sets of movable rings 13 to drive the two sets of locking rods 14 to quickly insert into the positioning holes 17 or locking sleeves 18.

[0037] This utility model provides a pressure testing device for building inspection, the specific working principle of which is as follows:

[0038] When using this equipment, pull out the collection box 7 to ensure it is empty, place the sample on the load-bearing plate 5, close the protective plate 10, and the two sets of locking rods 14 will automatically insert into the two sets of positioning holes 17 under the action of the return spring 16 to lock. Then, let the first hydraulic cylinder 2 drive the lower pressure plate 3 to pressurize the sample, and the second hydraulic cylinder 4 adjusts the position of the load-bearing plate 5 to adapt to different samples. Let the observation window 11 display the test status in real time, and let the impact debris fall into the collection box 7. After the test, pull the horizontal pull handle 15 to unlock the protective plate 10. After sliding open, the protective plate 10 can be used to remove the sample debris. Then, pull out the collection box 7 through the buckle groove 8 to clean the debris, and reset it to prepare for the next test.

[0039] The electrical components mentioned in this article are all electrically connected to an external main controller and industrial power supply, and the main controller can be a conventional known device such as a computer that provides control.
