Detailed Description
Applicants first describe herein, throughout the specification and claims that follow, the directional terms used in reference to the drawings shall be interpreted relative to the directional terms used in the claims. Next, in the embodiments and drawings to be described below, the same reference numerals are used to designate the same or similar components or structural features thereof.
Referring to fig. 1 and 2, the doorframe 11 shown in fig. 2 has an upper frame strip 12 and two side frame strips 13, the top ends of the two side frame strips 13 are connected to the two opposite ends of the upper frame strip 12, the top edge of the door panel 14 shown in fig. 2 has a recess 15 and a blocking wall 16, the bottom surface of the recess 15 has a receiving groove 17, and the blocking wall 16 is adjacent to the outer side surface of the recess 15.
Referring to fig. 2 again, the door closer assembly 10 of the present invention includes a sliding rail 20, a sliding block 24, a door closer 40 and a main arm 50.
The slide rail 20 is made of metal and is fastened to the bottom surface of the upper frame strip 12 of the door frame 11 by a fastening element 21 such as a screw. The slide rail 20 has a slide groove 22, two ends of the slide rail 20 are respectively provided with an end cover 25, and the two ends of the slide groove 22 are sealed by the two end covers 25. As shown in fig. 4, the cross-sectional shape of the slide groove 22 is T-shaped and includes a single large groove portion 23 and a small groove portion 24 communicating the large groove portion 23.
The slider 30 is made of a plastic material. As shown in fig. 3 and 4, the slider 30 has a large ring portion 31 and a small ring portion 32 coaxially connecting the large ring portion 31, so that the slider 30 has a circular cross-sectional shape at both positions. The sliding block 30 is embedded in the large and small groove portions 23, 24 of the sliding groove 22 by the large and small ring portions 31, 32, respectively, so that the sliding block 30 can move along the sliding groove 22 and be blocked by the two end covers 25 without falling out from the two ends of the sliding groove 22.
The door closer 40 is embedded in the receiving groove 17 of the door panel 14 and covered by a fixing piece 42, and the fixing piece 42 is locked to the door panel 14 by a fixing member 43 such as a screw. The door closer 40 has a transmission shaft 41, the top end of the transmission shaft 41 passes through the fixing piece 42 and protrudes out of the accommodating groove 17 of the door panel 14, when the transmission shaft 41 rotates under the action of external force, the door closer 40 can generate resistance to provide a buffering effect. Since the door closer 40 is a conventional door closer, further details and operation principles are not repeated herein for the sake of brevity.
The main arm 50 is made of a metal material. One end of the main arm 50 is pivotally connected to the sliding block 24, and more specifically, one end of the main arm 50 has a protruding shaft 51, as shown in fig. 4, the protruding shaft 51 has a large shaft portion 52 and a small shaft portion 53 coaxially connected to the large shaft portion 52, and the large and small shaft portions 52, 53 of the protruding shaft 51 are respectively sleeved by the large and small ring portions 31, 32 of the sliding block 30, so that the sliding block 30 can freely rotate relative to the protruding shaft 51 to form a pivoting effect. In addition, the other end of the main arm 50 has a rectangular hole 54, and the main arm 50 is fastened to the top end of the transmission shaft 41 of the door closer 40 through the rectangular hole 54, so that the main arm 50 pulls the slider 24 to move in the sliding slot 22 during the opening or closing process of the door panel 14, and drives the transmission shaft 41 of the door closer 40 at the same time, so that the door closer 40 provides a buffering effect to stabilize the door panel 14.
Therefore, the utility model discloses a slider 30 that door closer assembly 10 provided presents with circular cross section's mode, seems comparatively mellow and not have edges and corners in appearance for slider 30 can effectively reduce and slide rail 20 between the mutual friction, and then reaches the effect of eliminating abnormal sound and promoting and actuate smooth and easy degree, and further lets door plant 14 can both be more smooth and easy more stable opening and the process of closing. It should be noted that there are many ways to mount the sliding rail 20 on the door frame 11 and the door closer 40 on the door panel 14, and this is only one of them, and since how to mount the sliding rail 20 and the door closer 40 is not the focus of the present application, it is not necessary to describe any other possible mounting manners herein.
