[0032] The present invention will be further described below with reference to the embodiments.

[0033] pass Figures 1-5 As can be seen, the cabinet door opening and closing life testing device is equipped with a support frame 1. Front support rods 4 are fixed on the left and right sides of the front end of the support frame 1, respectively. The front support rods 4 are used to install relevant test components. A cabinet door fixing plate 2 is fixed in the middle of the support frame 1. The cabinet door fixing plate 2 is used to fix the cabinet door to be tested. It can be installed and fixed on the left or right side of the cabinet door fixing plate 2 according to the actual opening direction of the cabinet door.

[0034] The support frame 1 has rear support rods 3 on the left and right sides at the rear end, and the rear support rods 3 are also used to install relevant test components.

[0035] Front slide rails 6 are fixedly installed at the front end of the front support rods 4 on both the left and right sides. Front sliders 11 are installed at the front end of the two front slide rails 6 respectively. The two front sliders 11 are slidably connected to the two front slide rails 6 respectively. The front sliders 11 can slide up and down on the front slide rails 6. Rear slide rails 5 are fixedly installed at the front end of the rear support rods 3 on both the left and right sides. Rear sliders 8 are installed at the front end of the two rear slide rails 5 respectively. The two rear sliders 8 are slidably connected to the two rear slide rails 5 respectively. The rear sliders 8 can slide up and down on the rear slide rails 5.

[0036] The two front sliders 11 are slidably connected to the two front slide rails 6 respectively, and the two rear sliders 8 are slidably connected to the two rear slide rails 5 respectively. This design is for cabinet doors of different heights. For example, when the cabinet door to be tested is high, the front sliders 11 and the rear sliders 8 need to be moved upwards synchronously to the position of the cabinet door handle. This design has a wide range of applications and few limitations.

[0037] A cylinder 7 is provided at the front end of each of the two rear sliders 8. The rear end of the cylinder 7 is rotatably connected to the rear slider 8. A rotating bracket 12 is provided on each of the two front sliders 11. The rotating bracket 12 is rotatably connected to the front slider 11. The front end of the piston rod on each of the two cylinders 7 is rotatably connected to one end of each of the two rotating brackets 12. The other end of each of the two rotating brackets 12 is connected to a pull rod 13.

[0038] like Figure 1 As shown, regarding the specific structure of the rotating bracket 12, in this patent, the rotating bracket 12 is L-shaped. When the piston rod of the cylinder 7 is in the retracted state, the two ends of the corresponding two L-shaped rotating brackets 12 are facing the left and right sides and the front side, respectively. When the piston rod of the cylinder 7 moves forward, the two corresponding L-shaped rotating brackets 12 rotate inward.

[0039] Two cylinders 7 can drive the corresponding rotating brackets 12 to rotate inward and outward respectively. While the rotating brackets 12 are rotating, the pulling rod 13 is rotated synchronously. The following is an explanation using a left-opening cabinet door as an example. When using it, first, install the hinges at the top and bottom of the left side of the cabinet door onto the left side of the cabinet door fixing plate 2. At this time, the cabinet door can be opened and closed to the left on the cabinet door fixing plate 2. The operating cylinder 7 is in the push-open state. Then, use a rope-like item to connect the handle of the cabinet door to the pulling rod 13. Start the operation of the cylinder 7. During the retraction and advancement of the cylinder 7, the cabinet door is opened and closed to perform the opening and closing life test of the cabinet door. During the test, no manual operation is required, and the test efficiency is high. Since the test device uses cylinders combined with related mechanical components for driving, the operation reliability is high and labor costs are saved.

[0040] In this patent, for multiple rotating connection methods, two L-shaped rotating brackets 12 are respectively hinged and fixed to the front slider 11, the rear ends of the two cylinders 7 are respectively hinged and fixed to the rear slider 8, and the front ends of the piston rods of the two cylinders 7 are respectively hinged and fixed to one end of the two rotating brackets 12. By hinged fixing, the stability of long-term rotation between related components can be increased. Other rotating structures, such as gear drive, rack drive, chain drive, etc., can also be used.

[0041] In order to achieve real-time monitoring of the testing process, in this patent, counters 9 are respectively installed on the outer side of the cylinder barrel of the two cylinders 7 at the rear end position. When the cylinder retracts to the sensing position of the counter 9, the counter count is incremented by one, and the number of tests can be viewed in real time. In addition, timers 10 are respectively installed on the front support rods 4 on the left and right sides, and the test time can be viewed in real time through the timers 10.

[0042] To facilitate remote monitoring by operators, in this patent, both the counter 9 and the timer 10 are connected to indicator lights and buzzers. When the number of tests or the test time reaches the set value, the indicator lights and buzzers emit corresponding notification signals.

[0043] The two rear slide rails 5 and the two front slide rails 6 are respectively provided with scale lines 15 of the same height on the front end face. When dealing with cabinet doors of different heights, the rear slide slider 8 and the front slide slider 11 need to be adjusted up and down synchronously to ensure that the cylinder 7 and the rotating bracket 12 are at the same operating height, so as to avoid bending and twisting of related parts and affect the smoothness of the cylinder 7 driving the rotating bracket 12 to rotate.

[0044] For cabinet doors of different widths, the pull rod 13 in this patent is a telescopic structure. When the cabinet door is narrow, the length of the pull rod 13 can be retracted to meet the testing requirements of narrower cabinet doors. Conversely, when the cabinet door is wide, the length of the pull rod 13 is extended.

[0045] To improve the reliability of the connection between the cabinet door and the pull rod 13, this patent provides a connection fixing hole 16 at the front end of the pull rod 13. When the cabinet door is connected to the pull rod 13, one end of the rope can pass through the connection fixing hole 16 and be securely locked to ensure the stability of the connection between the cabinet door and the pull rod 13 during long-term opening and closing tests.

[0046] like Figure 1 , Figure 2 As shown, fixing plates 14 are provided at multiple locations on the support frame 1, cabinet door fixing plate 2, rear support rod 3, and front support rod 4. The fixing plates 14 have holes for installing and fixing the testing device.

[0047] This testing device has complete test drive devices on both the left and right sides, which can be used to test cabinet doors with left-opening, right-opening, and double-opening doors respectively, making it more widely applicable and less limited.

[0048] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
