DETAILED DESCRIPTION

[0035] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0036] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0037] Embodiment 1:

[0038] A door lock cylinder strength testing device, such as Figure 1-Figure 8 As shown, it includes a cabinet 1, and the interior of the cabinet 1 is respectively provided with an upper clamp 4 and a lower clamp 6 for fixing the two ends of the lock core 5. The lower clamp 6 is arranged on the inner side of the bottom of the cabinet 1, and a force-applying part 3 is arranged on the top of the upper clamp 4. The force-applying part 3 is transmitted and matched with the interior of the cabinet 1 through the lifting drive part 2.

[0039] The force-applying part 3 includes an outer shell 13 and a guide rod 10 movably connected to the inside of the outer shell 13. The upper clamp 4 is fixed to the bottom outer wall of the guide rod 10 by bolts. The inner wall of the outer shell 13 is only longitudinally slidably connected to a slider 14. A spiral groove 15 is provided on the outer wall of the guide rod 10. An arc head limiting rod 7 is fixed to the inner wall of the slider 14. The arc head limiting rod 7 is movably limited and matched to the inner wall of the spiral groove 15.

[0040] A permanent magnet 8 is fixed to the top outer wall of the slider 14 by bolts, and an electromagnet 9 used in conjunction with the permanent magnet 8 is fixed to the inner wall of the housing 13 .

[0041] When the device is in use, one end of the lock core 5 is placed in the lower clamping head 6, and then the lifting and lowering driving part 2 controls the force applying part 3 to rise and fall until the upper clamping head 4 is matched with the other end of the lock core 5, and then current is passed into the electromagnet 9, so that a magnetic field is generated in the electromagnet 9. The electromagnet 9 has the same magnetic pole as the opposite side of the permanent magnet 8, and a magnetic repulsion force is generated, so that the slider 14 is subjected to a downward force, so that the arc head limiting rod 7 applies a vertical downward force to the spiral groove 15. Since the upper clamping head 4 is in contact with the top of the lock core 5 and cannot move, the force of the arc head limiting rod 7 on the spiral groove 15 will make the spiral groove 15 have a rotation tendency, so that the upper clamping head 4 applies a torsional force to the lower clamping head 6.

[0042] The other end of the guide rod 10 is fixed with a movable disk 12 by bolts, the bottom of the movable disk 12 is buckled with a spring 11, and the other end of the spring 11 is buckled with the inner wall of the shell 13.

[0043] The device, by setting components such as the arc head limit rod 7 and the spiral groove 15, serves as one of the links for force transmission, so that the interaction between the arc head limit rod 7 and the spiral groove 15 can be utilized, so that the upper clamping head 4 can not only apply longitudinal pressure to the lock core 5, but also apply torsional force to the lock core 5, thereby increasing the comprehensiveness of the detection, and the drive of the two is realized by relying on the same power source, which simplifies the structural layout and control logic.

[0044] In order to solve the comprehensive problem; Figure 4 As shown, the inner wall of the lower clamp 6 is slidably connected with a guide rail 18, and the guide rail 18 is fixed to the inner wall of the cabinet 1 by bolts, and a permanent magnet 16 is fixed to the outer wall of one side of the lower clamp 6 by bolts, and an electromagnet 17 is fixed to the inner wall of the cabinet 1 at a position opposite to the permanent magnet 16 by bolts, and a spring 19 is buckled to the outer wall of the other side of the lower clamp 6, and the other end of the spring 19 is buckled to the inner wall of the cabinet 1, and a current with periodic changes in size flows through the electromagnet 17.

[0045] In the process of applying pressure and torque, a periodically changing current will be passed through the electromagnet 17, thereby generating a periodically changing magnetic repulsion force between the permanent magnet 16 and the electromagnet 17. When the magnetic repulsion force is greater than the elastic force of the spring 19, the resultant force acting on the lower chuck 6 points to the side of the spring 19. When the magnetic repulsion force is less than the elastic force of the spring 19, the resultant force acting on the lower chuck 6 points to the side of the spring 19.

[0046] This device, by providing structures such as permanent magnet 2 16, electromagnet 2 17, spring 2 19, etc., can utilize the current with periodic changes in size in permanent magnet 2 16, thereby combining with the elastic force of spring 2 19 to enable the lower clamp 6 to apply a lateral force that periodically changes left and right to the lock core 5, thereby applying a bending moment to the lock core 5, adding a bending moment fatigue strength test, and further increasing the comprehensiveness of the detection.

[0047] In order to solve the lifting problem; Figure 5 As shown, the lifting drive unit 2 includes a telescopic rod 21 and a plurality of guide columns 20, wherein the guide columns 20 are fixed to the top outer wall of the outer shell 13 by bolts, and the guide columns 20 are slidably connected to the inner wall of the cabinet 1, and the telescopic rod 21 is fixed to the top outer wall of the cabinet 1 by bolts, and the telescopic end of the telescopic rod 21 is fixed to the top outer wall of the outer shell 13 by bolts.

[0048] When the telescopic rod 21 is extended or retracted, it can drive the housing 13 to move up or down, and the guide column 20 can provide guidance.

[0049] In order to solve the sealing problem; Figure 6 As shown, a symmetrical cabinet door 22 is rotatably connected to the end surface of the cabinet body 1, a perspective window 23 is fixedly embedded in the inner wall of the cabinet door 22, and a handle 24 is fixed to the outer wall of the cabinet door 22 by bolts.

[0050] During the test, the two cabinet doors 22 can be closed to keep the entire cabinet body 1 relatively sealed. During the test, the test process can be observed through the perspective window 23.

[0051] When the present embodiment is in use, one end of the lock core 5 is placed in the lower clamp 6, and then the lifting drive unit 2 controls the force applying unit 3 to rise and fall until the upper clamp 4 is matched with the other end of the lock core 5, and then a current is passed into the electromagnet 9, so that a magnetic field is generated in the electromagnet 9. The electromagnet 9 has the same magnetic pole as the opposite side of the permanent magnet 8, and a magnetic repulsion force is generated, so that the slider 14 is subjected to a downward force, so that the arc head limit rod 7 applies a vertical downward force to the spiral groove 15. Since the upper clamp 4 is in contact with the top of the lock core 5 and cannot move, the upper clamp 4 is The force of the arc head limit rod 7 on the spiral groove 15 will make the spiral groove 15 have a rotation tendency, so that the upper chuck 4 applies a torsional force to the lower chuck 6. In the process of applying pressure and torque, a periodically changing current will be passed through the electromagnet 2 17, so that a periodically changing magnetic repulsion force is generated between the permanent magnet 2 16 and the electromagnet 2 17. When the magnetic repulsion force is greater than the elastic force of the spring 2 19, the resultant force received by the lower chuck 6 points to the side of the spring 2 19. When the magnetic repulsion force is less than the elastic force of the spring 2 19, the resultant force received by the lower chuck 6 points to the side of the spring 2 19.

[0052] Embodiment 2:

[0053] A door lock cylinder strength testing device, such as Figure 7 , 8 As shown, in order to solve the problem of random test force control; this embodiment makes the following improvements on the basis of embodiment 1: a random power control component is arranged inside the cabinet 1, and the random power control component includes a fixed ring 25, an intermittent turntable 26 and a motor 27, the fixed ring 25 is fixed to the inner wall of the cabinet 1 by bolts, the intermittent turntable 26 is rotatably connected to the inner wall of the fixed ring 25, the motor 27 is fixed to the outer wall of the cabinet 1 by bolts, the outer wall of the output shaft of the motor 27 is connected to a rotating shaft 28 through a coupling, the rotating shaft 28 is rotatably connected to the inner wall of the intermittent turntable 26, and the outer wall of the rotating shaft 28 is buckled with a coil spring 33, and the other end of the coil spring 33 is buckled to the inner wall of the intermittent turntable 26.

[0054] The side wall of the fixing ring 25 is provided with a plurality of groups of card slots in a double-layer circular array, the inner walls of the card slots are fixedly embedded with electrode head 1 29 and electrode head 2 30, and the side wall of the intermittent turntable 26 is slidably connected with a connecting electrode 31, both ends of the connecting electrode 31 are in contact with and fit with one of the electrode head 1 29 and the electrode head 2 30, and the back of the connecting electrode 31 is buckled with a spring 32, and the other end of the spring 32 is buckled with the inner wall of the intermittent turntable 26.

[0055] The corresponding electrode head 1 29 is connected in series with the electrode head 2 30 , and a resistor 34 is also connected in series. Multiple groups of electrode heads 1 29 and electrode heads 2 30 are arranged in parallel, and are connected in parallel with the electromagnet 1 9 , the electromagnet 2 17 , and the motor 27 .

[0056] The resistance values ​​of all the resistors 34 are different.

[0057] When the present embodiment is in use, when the motor 27 is started, it can drive the rotating shaft 28 to rotate. At this time, due to the limiting effect of the connecting electrode 31 and the card slot between the intermittent turntable 26 and the fixing ring 25, the intermittent turntable 26 does not rotate. During the rotation of the rotating shaft 28, the coil spring 33 gradually deforms, so that the rotational driving force of the rotating shaft 28 on the intermittent turntable 26 gradually increases, until the rotational driving force of the coil spring 33 on the intermittent turntable 26 is greater than the elastic limiting force between the connecting electrode 31 and the card slot, the connecting electrode 31 overcomes the elastic force of the spring 32 and contracts inward, so that the intermittent turntable 26 rotates rapidly, and the coil spring 33 deforms in the direction of returning to the original position. After the intermittent turntable 26 drives the connecting electrode 31 to rotate to the next slot, the connecting electrode 31 is limited again. With the continuous rotation of the rotating shaft 28, the intermittent turntable 26 rotates intermittently, so that the connecting electrode 31 contacts with different groups of electrode heads 1 29 and electrode heads 2 30. When electrode heads 1 29 and electrode heads 2 30 contact the connecting electrode 31, the connecting electrode 31 connects electrode heads 1 29 and electrode heads 2 30, so that electromagnet 1 9, electromagnet 2 17, and motor 27 are energized, and the resistance value of each resistor 34 is different, so that the voltage division of electromagnet 1 9, electromagnet 2 17, and motor 27 is different each time they contact.

[0058] This device utilizes a mechanical switching operation to enable the current magnitudes of the electromagnet 1 9 and the electromagnet 2 17 to change periodically, thereby being able to match the actual scenario where the lock cylinder 5 is subjected to different forces when in use, thereby increasing the matching degree between the test result and the actual situation.

[0059] This device uses the motor 27 as a switching drive, and the voltage division of the motor 27 will also change, so that the period of intermittent switching of the intermittent turntable 26 will change. Combined with the change in the current magnitude of the electromagnet 1 9 and the electromagnet 2 17, the current magnitude of the electromagnet 1 9 and the electromagnet 2 17 and the period of current change will change, thereby realizing double superposition and increasing randomness.

[0060] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
