[0026] Reference Figure 1-Figure 2 According to an embodiment of the utility model, an adjustable door closer housing clamp for clamping two door closer housings that can be interlocked with each other includes a base plate 11, and the upper side of the base plate 11 is fixedly provided with two brackets 12 distributed front and back, and the two door closer housings can be hung on the brackets 12, and the upper side of the base plate 11 is also provided with a pressing component 101 for pressing the door closer housing downward to lock it.

[0027] The pressing assembly 101 includes a piston cylinder 16, and a piston rod 17 extending from the piston cylinder 16 is hinged to a pressure plate No. 18. A fixed plate is fixed on the piston cylinder 16, and a hinged plate 19 is hinged on the upper side of the fixed plate and is also hinged to the pressure plate No. 18. That is, when the piston cylinder 16 controls the piston rod 17 to move upward, the other end of the hinged plate 19 connected thereto will be pressed downward.

[0028] The bottom plate 11 is provided with three pressing assemblies 101, wherein two first pressing plates 18 in two pressing assemblies 101 are arranged facing each other and can press on the left and right ends of the two door closer housings;

[0029] The hinged plate 19 in the third pressing assembly 101 is arranged forward and is used to press down the auxiliary material rod 20. The auxiliary material rod 20 is used to connect the two door closer shells mounted on the bracket 12, and the auxiliary material rod 20 is covered with two abutment plates 21 that can abut against the door closer shells to limit the distance between the two door closer shells. At this time, the two door closer shells are completely locked.

[0030] In the second embodiment of the adjustable door closer housing clamp, a bearing platform 22 is further provided on the upper side surface of the base plate 11, and a lifting plate 23 that can slide up and down is connected to the bearing platform 22 through a spring, and two mounting plates 24 distributed on the left and right are fixedly provided on the upper side surface of the lifting plate 23, and a receiving groove is provided on the upper side surface of the mounting plate 24, and the front and rear widths of the receiving grooves are adapted to the front and rear widths of the auxiliary material rod 20. The staff can keep the auxiliary material rod 20 in the receiving grooves, so as to facilitate the two door closers to be put on the outside of the auxiliary material rod 20, and when the door closer housing is pressed down until it abuts against the bracket 12, the spring will be compressed to avoid affecting the clamping of the door closer housing.

[0031] In the third embodiment of the adjustable door closer housing clamp, in order to enable the adjustable door closer housing clamp to clamp door closer housings of various specifications, the front-to-back spacing between the brackets 12 needs to be adjustable, and a boss 13 is fixedly provided on the upper side surface of the base plate 11, and a threaded shaft 14 is rotatably connected inside the boss 13, and two opposite sections of threads are machined on the threaded shaft 14, and the two sections of threads are respectively connected to the two brackets 12, and the two brackets 12 are slidably connected to the upper side surface of the base plate 11 front and back, and a knob 15 is provided at the front end of the threaded shaft 14, and the staff can rotate the knob 15 to drive the brackets 12 to move toward each other, thereby adjusting the spacing between the brackets 12 so that the door closer can be clamped between the brackets 12.

[0032] In addition, since the widths of door closers of different specifications are different, the abutment plate 21 is slidably connected to the outside of the auxiliary material rod 20 left and right, and the abutment plate 21 maintains a relative position relationship with the auxiliary material rod 20 through a locking screw. The staff can adjust the distance between the abutment plates 21 to adjust the spacing between the two door closer housings, so that the hinged plates 19 in the two oppositely arranged downward pressing assemblies 101 can be pressed on one side of the door closer housing.

[0033] In addition, in order to ensure stable clamping, a fixing groove 25 is provided in the side surfaces of the two brackets 12 that are close to each other, and an adapter plate 26 is embedded in the fixing groove 25.
