Description

Technical Field

[0001] The utility model relates to the technical field of door closer testing equipment, in particular to door closer testing equipment. Background Art

[0002] When the door closer is put into use, its performance needs to be tested. It is tested by simulating the opening and closing of the door so that it can work during the test to ensure that the door closer can be used normally and prevent the product from being damaged during normal use. After searching, the patent with the announcement number cN218628932U discloses a door closer life tester, including a test door, a door opening device and a counting device. The test door includes a door frame, a door leaf hinged to the door frame, and a door closer installed between the door frame and the door leaf; the door opening device includes a vertically arranged fixed frame arranged on the front side of the door leaf, and a plurality of door opening mechanisms installed at different heights on the fixed frame. The door opening mechanism includes a cylinder, and the cylinder is provided with a piston rod for pushing the door leaf to open the door. The piston rod stroke of each door opening mechanism is different; the counting device includes a counting sensor arranged on the door frame. Since the stroke of each piston rod is different and the opening and closing angle of the door leaf is different, the test result is closer to the actual situation, and each door opening mechanism works in turn, so the cylinder is not easy to be damaged, thereby improving the service life of the tester. However, when the detection device is testing the door closer, the cylinder is extended and retracted to drive the piston rod to push the door, and the position where the piston rod pushes the door is close to the hinged position with the door panel, which is also the position that requires the greatest pushing force. Therefore, long-term detection work will increase the fatigue of the cylinder and cause it to be damaged. At the same time, one cylinder can only push one door panel, which wastes resources and reduces the detection strength. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a door closer testing device, which solves the problem that when the detection device is testing the door closer, the piston rod is driven by the extension and retraction of the cylinder to push the door, and the position where the piston rod pushes the door is close to the position where the door panel is hinged, which is also the position where the greatest pushing force is required. Therefore, long-term detection work will increase the fatigue of the cylinder and cause it to be damaged, and at the same time, one cylinder can only push one door panel, which wastes resources and reduces the detection strength.

[0004] To achieve the above objectives, the utility model is implemented through the following technical solutions: a door closer testing device, comprising a mounting frame and a cylinder, a front end side wall of the mounting frame is fixedly mounted with a plurality of fixing plates, and a door panel is arranged at the lower end of each fixing plate, the right end of each door panel is hinged to the front end right side wall of the mounting frame, a door closer is fixedly mounted between the fixing plate and the door panel, a mounting plate is fixedly mounted on the right side of the mounting frame, a rotating plate is rotatably connected to the upper end of the mounting plate, a cylinder is fixedly mounted on the upper end of the rotating plate, a supporting plate is fixedly mounted on the output shaft of the cylinder, a plurality of push rods are fixedly mounted on the left end side wall of the supporting plate, and each push rod corresponds to a door panel one by one, a roller is rotatably connected inside the left end of the push rod, and the right end of the door panel protrudes from the right end side wall of the mounting frame to the outside.

[0005] Preferably, the upper end of the mounting plate is rotatably connected to a gear, and a gear ring is fixedly sleeved on the outer side wall of the rotating plate. The gear is meshingly connected to the gear ring, and a reciprocating motor is fixedly installed on the lower end of the mounting plate. The output shaft of the reciprocating motor is fixedly connected to the lower end of the gear by passing through the interior of the mounting plate, so that the rotating plate can be conveniently driven to rotate by the gear.

[0006] Preferably, the mounting plate is L-shaped, and the support plate is located between the mounting frame and the mounting plate, thereby preventing the position of the mounting plate from hindering the movement of the support plate.

[0007] Preferably, the roller does not contact the outer side wall of the mounting frame, thereby preventing the roller from being obstructed by the side wall of the mounting frame, causing it to be unable to move conveniently.

[0008] Preferably, the roller of the rotating plate when it is in the initial position fits with the side wall of the door panel in the initial position, thereby preventing the roller from being unable to push the door panel.

[0009] The utility model provides a door closer testing device, which has the following beneficial effects:

[0010] 1. When using the door closer test device, through the cooperation between the provided support plate and the installed multiple push rods, one cylinder can conveniently push multiple door panels, thereby improving the efficiency of detection and not wasting resources;

[0011] 2. When using the door closer testing device, by making the right end of the door panel protrude from the right end of the mounting frame and arranging the cylinder at the right end of the door panel, and by using the drag rod to push through the right end of the door panel, the pushing force on the cylinder can be reduced, thereby extending the service life of the cylinder.
