Description

Technical Field

[0001] This utility model belongs to the field of testing equipment technology and relates to a lock performance testing machine. Background Technology

[0002] The latch is mounted on the lock body. When the door opens or closes, the door frame pushes the latch into the lock body. After the door closes or closes, a spring inside the lock body pushes the latch outward to return to its original position. Currently, there is a lack of a testing machine that can be used to test the lifespan of the spring.

[0003] There is an opening in the door frame. When the door is closed, the latch extends into this opening under the action of a spring. When opening or closing the door, the latch will contact the side of the opening in the door frame. If the pressure applied by the latch to the opening in the door frame is too great, it indicates that the lock body is faulty. Currently, there is a lack of a testing machine that can detect the pressure value applied by the latch to the opening in the door frame to determine whether the lock body is qualified. Utility Model Content

[0004] The purpose of this invention is to provide a testing machine that can detect the service life of the latch spring inside the lock body and the pressure value applied by the latch to the door frame opening, in response to the existing lock body structure.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A lock performance testing machine is characterized by comprising a frame and a testing platform mounted on the frame. The testing platform has several testing stations, each corresponding to a lock body. Each testing station is equipped with a fixing component for fixing the lock body, a driving component for driving the extension and retraction of the latch, and a simulation component for simulating the position of a door frame. The fixing component presses and fixes the lock body to the testing station. The driving component drives the latch to extend into the lock body, and a spring in the lock body pushes the latch to extend out of the lock body. When the latch extends and retracts, it abuts against the simulation component. The testing station is also equipped with a testing element connected to the simulation component for detecting the pressure applied to the simulation component when the latch extends and retracts.

[0007] In the aforementioned lock performance testing machine, the latch is rotatably mounted on the lock body via a rotating shaft; a slider is provided inside the lock body, which can translate relative to the lock body, and when the slider translates, it can drive the latch to rotate around the rotating shaft.

[0008] In the aforementioned lock performance testing machine, the driving component includes a cylinder, and a push block is fixedly provided at the end of the cylinder. The cylinder drives the push block to move back and forth. The push block extends outward to abut against the slider and pushes the slider to move, so that the latch extends into the lock body. The push block retracts inward to separate from the slider, and the spring in the lock body pushes the latch to extend out of the lock body, and the latch and slider are reset.

[0009] In the aforementioned lock performance testing machine, the spring includes a torsion spring, which is sleeved on the aforementioned rotating shaft.

[0010] In the aforementioned lock performance testing machine, the fixing component includes a pressure block and a second cylinder. The pressure block is rotatably mounted on the testing platform via a pin. The end of the second cylinder is fixedly connected to the pressure block. The second cylinder drives the pressure block to rotate around the pin. When the pressure block flips downward, it abuts against the lock body and presses the lock body tightly onto the testing platform.

[0011] In the aforementioned lock performance testing machine, the fixing component further includes a pressure plate and a cylinder three. The pressure plate is fixedly connected to the end of the cylinder three. The cylinder three can drive the pressure plate to rotate and rise and fall. The cylinder three drives the pressure plate to rotate above the lock body. The cylinder three drives the pressure plate to descend and abut against the lock body, pressing the lock body tightly on the testing platform.

[0012] In the aforementioned lock performance testing machine, the fixing component further includes several limiting pins fixed on the testing platform. Each limiting pin abuts against the outer surface of the lock body to limit the horizontal displacement of the lock body.

[0013] In the aforementioned lock performance testing machine, the testing element includes a pressure sensor.

[0014] In the aforementioned lock performance testing machine, the simulation component is fixedly connected to the pressure sensor via a connector, which is vertically slidably mounted on the testing platform via a slide rail; the pressure sensor is mounted on the testing platform via a cylinder, which is fixedly mounted on the testing platform, and the pressure sensor is fixedly mounted at the end of the cylinder.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. By pushing the push block back and forth with the cylinder, the latch is repeatedly extended and retracted, thus testing the lifespan of the spring; by using the cylinder instead of the key, the force required to turn the latch can be tested.

[0017] 2. A simulated component is used to represent the position of the opening side on the door frame. Each time the latch extends or retracts, it will abut against the simulated component and apply pressure to it. The pressure value can be accurately determined by a pressure sensor connected to the simulated component. If the pressure value is greater than 10N, it indicates that there is a problem with the lock, which helps to determine whether the lock body is qualified.

[0018] 3. The horizontal displacement of the lock body is limited by the limit pin, and the vertical displacement is limited by the pressure block or the pressure block pressing down on the lock body, thereby fixing the lock body on the detection platform, which has a high degree of automation.

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] like Figure 1 and Figure 2 As shown, the lock performance testing machine of this utility model is characterized by comprising a frame 1 and a testing platform 2 disposed on the frame 1. The testing platform 2 is provided with several testing stations, each of which can be used to place a lock body 3. Each testing station is provided with a fixing component for fixing the lock body 3, a driving component for driving the extension and retraction of the latch 4, and a simulation component 18 for simulating the position of a door frame. The fixing component presses and fixes the lock body 3 on the testing station. The driving component drives the latch 4 to extend into the lock body 3. The spring 6 inside the lock body 3 pushes the latch 4 to extend out of the lock body 3. When the latch 4 extends and retracts, it abuts against the simulation component 18. The testing station is also provided with a testing element, which is connected to the simulation component 18 and is used to detect the pressure applied to the simulation component 18 when the latch 4 extends and retracts.

[0027] like Figure 3As shown, the latch 4 is rotatably mounted on the lock body 3 via a pivot 5. A slider is located inside the lock body 3, capable of translating relative to the lock body 3. This translation of the slider causes the latch 4 to rotate around the pivot 5. The driving component includes a cylinder 7, with a push block 8 fixed to its end. The cylinder 7 drives the push block 8 to translate back and forth. The push block 8 extends outward to abut against the slider and pushes it to translate, causing the latch 4 to extend into the lock body 3. The push block 8 retracts inward to separate from the slider, and a spring 6 inside the lock body 3 pushes the latch 4 outward, resetting the latch 4 and the slider. The spring 6 includes a torsion spring, which is sleeved on the pivot 5.

[0028] like Figure 4 As shown, the fixing component includes a pressure block 9 and a second cylinder 10. The pressure block 9 is rotatably mounted on the detection platform 2 via a pin 11. The end of the second cylinder 10 is fixedly connected to the pressure block 9. The second cylinder 10 drives the pressure block 9 to rotate around the pin 11. When the pressure block 9 flips downward, it abuts against the lock body 3 and presses the lock body 3 firmly onto the detection platform 2. Figure 3 As shown, the fixing component also includes a pressure plate 12 and a cylinder 13. The ends of the pressure plate 12 and the cylinder 13 are fixedly connected. The cylinder 13 can drive the pressure plate 12 to rotate and move up and down. The cylinder 13 drives the pressure plate 12 to rotate above the lock body 3, and the cylinder 13 drives the pressure plate 12 to descend and abut against the lock body 3, pressing the lock body 3 firmly onto the detection platform 2. The fixing component also includes several limiting pins fixed on the detection platform 2. Each limiting pin abuts against the outer surface of the lock body 3 to limit the horizontal displacement of the lock body 3.

[0029] like Figure 5 As shown, the detection element includes a pressure sensor 14. The simulation component 18 is fixedly connected to the pressure sensor 14 via a connector 15, which is vertically slidably mounted on the detection platform 2 via a slide rail 16. The pressure sensor 14 is mounted on the detection platform 2 via a cylinder 17, which is fixedly mounted on the detection platform 2, and the pressure sensor 14 is fixedly mounted at the end of the cylinder 17. The cylinder 17 itself does not move; it only serves as a flexible mounting component for fixing the pressure sensor 14.

[0030] like Figure 1 and Figure 2 As shown, this embodiment has three testing stations, each equipped with a different type of lock body 3. Figure 3 and Figure 4 As shown, the positions of the lock body 3 and the latch 4 are different for different models, so the installation position of the drive component is also changed accordingly, and the structure and installation position of the fixing component are also changed accordingly.
