DETAILED DESCRIPTION

[0038] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0039] See also Figure 1-Figure 12 The present invention provides a door leaf hardware wear test device, comprising a door leaf mounting frame 1 and a driving mechanism 2 connected to a door leaf handle to drive the door leaf to complete an opening and closing action. The door leaf mounting frame 1 can be used to mount a test door leaf through the hardware to be tested, and the driving mechanism 2 drives the door leaf to continuously perform an opening and closing action to simulate the actual use scenario of the door leaf, thereby providing more reliable test data, thereby feeding back the wear condition of the door leaf hardware during the normal actual use of the door leaf.

[0040] like Figure 1 and Figure 3As shown, the driving mechanism 2 includes a moving platform 3, a driving shaft 8 vertically mounted on the top of the moving platform 3, and a swinging assembly 4 connected to the driving shaft 8; and a locking universal wheel (not shown) is installed at the bottom of the moving platform 3, and the driving shaft 8 is connected to a driving assembly 5 for driving it to rotate forward and reverse. After the door leaf is installed on the door leaf mounting frame 1 through the hardware to be tested, the moving platform 3 is pushed to move to the hinge of the door leaf, and after the swinging assembly 4 is connected to the door leaf handle, the swinging assembly 4 is driven by the driving shaft 8 to rotate forward and reverse continuously, so that the door leaf completes the opening and closing action.

[0041] like Figure 3 and Figure 4 As shown, the swing assembly 4 includes a connecting member 41, a transverse swing arm 42, a moving seat 43, a vertical swing arm 44 and a rotation driving portion 45. The connecting member 41 has a first connecting portion 411 connected to the drive shaft 8 and a second connecting portion 412 connected to the transverse swing arm 42; the moving seat 43 is slidably assembled on the top of the transverse swing arm 42 and can only slide along the length direction of the transverse swing arm 42, the vertical swing arm 44 is vertically installed at the center position of the top of the moving seat 43, and the rotation driving portion 45 is installed on the vertical swing arm 44. The rotation driving portion 45 is detachably connected to the handle and can drive the handle to rotate to complete the unlocking action.

[0042] like Fig.11 and Fig.12 As shown, when the driving shaft 8 rotates clockwise, the driving shaft 8 can make the transverse rocker arm 42, the movable seat 43, the vertical rocker arm 44 and the rotating drive part 45 rotate clockwise around the center line of the driving shaft 8 through the connecting member 41 and drive the door leaf to complete the closing action; during this process, the movable seat 43 will slide toward the top of the transverse rocker arm 42 away from the rotating shaft to avoid interfering with the closing action of the door leaf.

[0043] When the drive shaft 8 rotates counterclockwise, the drive shaft 8 can make the transverse rocker arm 42, the movable seat 43, the vertical rocker arm 44 and the rotating drive part 45 rotate clockwise around the center line of the drive shaft 8 through the connecting component 41 and drive the door leaf to complete the door opening action. During this process, the movable seat 43 will slide toward one end of the rotating shaft at the top of the transverse rocker arm 42 to avoid interfering with the door opening action.

[0044] The reason why the movable seat 43 slides is that the rotation center line of the transverse swing arm 42 is located on the side of the rotation center line of the door leaf.

[0045] It should be noted that after the door leaf is closed, the door lock hardware of the door leaf will complete the locking of the door leaf. Therefore, before opening the door leaf, the rotary drive unit 45 will drive the handle to rotate to complete the unlocking action to ensure that the door leaf opening and closing action can be carried out.

[0046] Furthermore, if Figure 3 , Figure 4 and Figure 5 As shown, the first connecting part 411 includes a ring body 4111 rotatably assembled on the driving shaft 8, a fan-shaped movable groove 4112 is opened on the top of the ring body 4111, a swing bar 4113 that can only move in the fan-shaped movable groove 4112 is installed on the driving shaft 8, and a counterweight assembly 6 is arranged at one end of the moving seat 43.

[0047] Based on the above design, when the driving shaft 8 rotates clockwise, before the swing bar 4113 of the driving shaft 8 contacts the end of the fan-shaped movable groove 4112, the connecting member 41 is in a stationary state, and the swing bar 4113 moves in the fan-shaped movable groove 4112. As the swing bar 4113 moves, when the swing bar 4113 contacts the fan-shaped movable groove 4112 close to the clockwise end, the swing bar 4113 continues to swing to push the ring body 4111 to rotate the connecting member 41. At this time, the horizontal swing arm 42, the moving seat 43, the vertical swing arm 44 and the rotating drive part 45 rotate together around the center line of the driving shaft 8 clockwise and drive the door leaf to complete the door closing action. In this process, since the moving seat 43 moves at the top of the horizontal swing arm 42 toward the end away from the connecting member 41 during the rotation, and a counterweight assembly 6 is also provided on the top of the moving seat 43 (refer to Fig.10 and Fig.11 As shown), therefore, when the moving seat 43 moves at the top of the transverse rocker arm 42, inertia will be generated, and the inertial force will increase the rotation speed of the transverse rocker arm 42, that is, acceleration will be generated. Since the rotation speed of the drive shaft 8 is constant, the swing bar 4113 on the drive shaft 8 will rotate counterclockwise in the fan-shaped active groove 4112 relative to the ring body 4111, that is, the swing bar 4113 will be separated from the end of the fan-shaped active groove 4112 close to the clockwise direction, and the door leaf completes the closing action in an accelerated manner. On the one hand, it can avoid the vibration generated by the impact when the door leaf contacts the door leaf mounting frame to act on the drive shaft 8, so that the drive component 5 can be protected. On the other hand, it can simulate the scenario in which the user gives a thrust to the door to make the door close by itself during normal use, thereby providing more reliable test data.

[0048] In addition, this scenario can also provide feedback on the telescopic elastic force of the door lock hardware. That is, in this scenario, if the door leaf cannot normally retract the door lock hardware to complete the locking of the door leaf, it means that the telescopic elastic force of the door lock hardware is relatively large.

[0049] It is worth mentioning that in actual use, when the drive shaft 8 rotates slowly, the centrifugal force generated by the transverse rocker arm 42 is small, and the moving seat 43 moves slowly. The inertial force of the moving seat 43 can be ignored, and the door leaf can rotate synchronously with the drive shaft 8 to complete the door closing action.

[0050] like Figure 7As shown, in a specific embodiment of the present invention, the rotation drive unit 45 includes a sliding sleeve 452 arranged on a positioning sleeve 451 on the vertical rocker arm 44, a sliding sleeve 452 sleeved on the positioning sleeve 451, a strip plate 453 fixed on the sliding sleeve 452 and parallel to the transverse rocker arm 42, and a driving structure 7 for driving the sliding sleeve 452 to slide on the positioning sleeve 451, a sliding seat 454 that can only slide along its length direction is slidably assembled on the strip plate 453, and a connecting piece 455 that is detachably connected to the handle is installed on the sliding seat 454 through a universal hinge structure, and a limiting screw is arranged on the positioning sleeve 451.

[0051] Based on the above design, the positioning sleeve 451 can slide on the vertical rocker arm 44 so that the connecting member 455 corresponds to the handle and completes the connection with the handle. The connecting member 455 can adopt the connecting structure in conventional technology, and it only needs to be satisfied with the fixation of the handle. During use, when the door leaf is closed, the driving structure 7 drives the sliding sleeve 452 to move downward and drives the strip plate 453 to move downward. At this time, the handle can be unlocked while rotating on the sliding seat 454.

[0052] In a specific embodiment of the present invention, the swing bar 4113 is made of aluminum alloy.

[0053] like Figure 5 As shown, in a specific embodiment of the present invention, the driving assembly 5 includes a housing 51, the bottom end of the driving shaft 8 extends through the housing 51 and rotates with the housing 51, a gear 52 is fixedly mounted on the driving shaft 8 in the housing 51, the driving assembly 5 also includes a rack 53 slidably mounted in the housing 51 through a sliding member 54, the rack 53 is meshed with the gear 52, the sliding member 54 is slidably matched with the side wall of the housing 51 and can only slide along the length direction of the rack 53, the driving assembly 5 also includes a rotating disk 55, an input shaft is fixed at the center position of the bottom of the rotating disk 55, the bottom end of the input shaft penetrates the housing 51 and rotates with the housing 51, the bottom end of the input shaft is fixedly connected to a driving source (not shown), a fixed column is vertically and eccentrically fixed to the other side of the rotating disk 55, a strip groove perpendicular to the rack 53 is opened on the sliding member 54, and the fixed column is adapted in the fixed column. The driving source is a motor in conventional technology.

[0054] Based on the above design, when in use, the motor drives the input shaft to rotate to rotate the rotating disk 55, and when the rotating disk 55 rotates, the cooperation between its fixed column and the strip groove of the sliding member 54 can make the rack 53 complete reciprocating movement along its own length direction, thereby making the gear 52 complete forward and reverse rotation, and the forward and reverse rotation of the gear 52 can make the drive shaft 8 complete continuous forward and reverse rotation, that is, the motor only needs to rotate continuously to make the drive shaft 8 continuously complete forward and reverse rotation.

[0055] like Figure 8 As shown, in the specific implementation of the present invention, a sliding frame 46 is provided at the top of the transverse swing rod 42 along its length direction, a strip-shaped through slot is provided at the top of the sliding frame 46, and the moving seat 43 includes a moving bar 431 adapted in the sliding frame 46 and a connecting section 432 provided at the top of the moving bar 431, the connecting section 432 passes through the strip-shaped through slot and extends to the top of the sliding frame 46, and rollers 433 are provided at the upper and lower sides of both ends of the moving bar 431. In order to reduce the sliding friction during the movement of the moving seat 43, on the one hand, the service life of the moving seat 43 can be improved, and on the other hand, the load during the rotation of the driving shaft 8 can be reduced. In addition, the inertial force of the moving seat 43 can also be improved.

[0056] like Figure 8 As shown, in a specific embodiment of the present invention, the counterweight assembly 6 includes a fixed seat 61 fixed to one end of the movable seat 43, a center rod 62 vertically arranged at the top center position of the fixed seat 61, and a plurality of counterweight plates 63 sleeved on the outside of the center rod 62, the outside of the center rod 62 has a thread, and a limiting nut 64 is also threadedly connected to the center rod 62.

[0057] Based on the above design, in actual use, the tester can adjust the gravity of the moving seat 43 by increasing or decreasing the number of the counterweight plates 63, and change the inertial force of the moving seat 43 when the rotation speed of the driving shaft 8 is constant.

[0058] like Figure 6 and Fig. 9 As shown, in a specific embodiment of the present invention, the driving structure 7 includes a first hydraulic telescopic part 71, a second hydraulic telescopic part 72, and a connecting pipe 73 connected between the first hydraulic telescopic part 71 and the second hydraulic telescopic part 72;

[0059] A first positioning plate 74 is vertically arranged on the top of the positioning sleeve 451, a second positioning plate 75 is arranged on the sliding sleeve 452, the first hydraulic telescopic part 71 is installed between the first positioning plates 74, the telescopic end of the first hydraulic telescopic part 71 is fixedly connected to the first positioning plate 74, and the fixed end of the first hydraulic telescopic part 71 is fixedly connected to the second fixed plate;

[0060] The clockwise rotation direction of the swing assembly 4 driven by the drive shaft 8 is the door closing direction, and the counterclockwise rotation direction of the swing assembly 4 driven by the drive shaft 8 is the door opening direction. A fan-shaped embedding groove is also provided on the ring body 4111 on the side of the fan-shaped movable groove 4112 close to the door opening direction, and the second hydraulic telescopic part 72 is embedded in the fan-shaped embedding groove, and the telescopic end of the second hydraulic telescopic part 72 extends from the end of the fan-shaped movable groove 4112 close to the door opening direction to the fan-shaped movable groove 4112.

[0061] Based on the above design, when the door leaf is closed, the first hydraulic telescopic part 71 is the shortest, the sliding bar is at the uppermost end of its sliding stroke, the handle is in horizontal rotation, and the second hydraulic telescopic part 72 is the longest, and the telescopic end of the second hydraulic telescopic part 72 is in the fan-shaped movable groove 4112. When in use, after the door leaf is closed, when the drive shaft 8 rotates counterclockwise, the swing bar 4113 on the drive shaft 8 rotates in the fan-shaped movable groove 4112. As the swing bar 4113 continues to rotate, when the swing bar 4113 contacts the telescopic end of the second hydraulic telescopic part 72, the second hydraulic telescopic part 72 will be shortened. At this time, the hydraulic oil in the second hydraulic telescopic part 72 is introduced into the second hydraulic telescopic part 72 through the connecting pipe 73. The first hydraulic telescopic part 71 is in the hydraulic telescopic part 71, and then the first hydraulic telescopic part 71 is extended. The extension of the first hydraulic telescopic part 71 will push the sliding sleeve 452 to slide downward on the positioning shaft sleeve 451 to unlock the handle. As the driving shaft 8 rotates continuously, when the swing bar 4113 contacts the end of the fan-shaped movable groove 4112 close to the door opening direction, the second hydraulic telescopic part 72 is the shortest, and the first hydraulic telescopic part 71 is the longest. The sliding bar is at the bottom of its sliding stroke, the handle is unlocked, and the driving shaft 8 continues to rotate to rotate the connecting member 41. The door leaf can be driven to complete the door closing action through the horizontal swing rod 42, the moving seat 43, the vertical swing rod 44 and the rotating driving part 45. That is, the driving shaft 8 of the present invention only needs to rotate forward and reverse continuously, which can not only complete the continuous opening and closing action of the door leaf, but also enable the door leaf to complete the automatic unlocking action. The whole process can be kept coherent without pausing, thereby improving the testing efficiency of the door leaf.

[0062] like Fig.10 As shown, specifically, the first hydraulic telescopic part 71 includes a hydraulic cylinder 711 fixed on the second positioning plate 75, a piston 712 slidably arranged in the hydraulic cylinder 711, and a piston rod 713 coaxially fixed to the top of the piston 712, the top end of the piston rod 713 passes through the top wall of the hydraulic cylinder 711 and extends to be fixedly connected to the first positioning plate 74, and a first connecting pipe 714 is arranged on one side of the bottom of the hydraulic cylinder 711;

[0063] The second hydraulic telescopic part 72 includes a fan-shaped hydraulic housing 721 adapted in the fan-shaped embedded groove, a fan-shaped plate 722 slidably arranged in the fan-shaped hydraulic housing 721, and an arc rod 723 arranged in the fan-shaped plate 722 close to the fan-shaped movable groove 4112, and one end of the arc rod 723 away from the fan-shaped plate 722 extends into the fan-shaped movable groove 4112, and one end of the fan-shaped hydraulic housing away from the arc rod 723 is provided with a second connecting pipe 724;

[0064] The connecting pipe 73 includes a straight pipe 731 fixed on the lateral swing arm 42 , a first hose 732 connected between one end of the straight pipe 731 and the first connecting pipe 714 , and a second hose 733 connected between the other end of the straight pipe 731 and the second connecting pipe 724 .
