DETAILED DESCRIPTION

[0020] See also Figure 1-Figure 5 A door closer comprises a door closer body 1, an assembled mounting mechanism 2 is installed on the left side of the door closer body 1, the assembled mounting mechanism 2 comprises a packaging plate 204, a damping T block 202 is installed on the surface of the packaging plate 204, one end of the damping T block 202 is fixedly connected with a mounting rod 201, a connecting rod 1 3 is installed on the front side of the door closer body 1, a connecting rod 2 4 is movably installed on the surface of the connecting rod 1 3, a stabilizing seat 8 is movably installed on the bottom of the surface of the connecting rod 2 4, and the surface of the stabilizing seat 8 is located on the connecting rod 2 4 The front side of the mounting base plate 7 is fixedly mounted, and the left side of the mounting base plate 7 is provided with a positioning and anti-slipping mechanism 6, which includes a fixing plate 601 and a boss 603. The boss 603 can be connected to the mounting head 5 and penetrate into the displacement groove 607 in the mounted state. The top and bottom of the surface of the fixing plate 601 are provided with displacement grooves 607. The displacement grooves 607 can meet the space requirements for the displacement plate 605 to move up and down. The left end of the boss 603 is fixedly connected with the mounting head 5;

[0021] See also Figure 2 and Figure 3 The surface of the packaging plate 204 is provided with T-slots 203 used in conjunction with the damping T-block 202. The number of T-slots 203 is several and evenly distributed on the surface of the packaging plate 204. By setting the damping T-block 202 and the T-slots 203, it can play a role in preventing the installation from falling off. In the installed state, it can prevent the installation rod 201 from moving left and right or moving up and down and leaving the packaging plate 204. At the same time, the damping T-block 202 can increase the contact friction with the T-slot 203, prevent the installation rod 201 from sliding randomly, free the operator's hands, and facilitate the subsequent bolt installation;

[0022] See also Figure 2 and Figure 3 The number of the damping T-blocks 202 is four, and a mounting hole 205 is formed through the surface of the mounting rod 201. By setting the mounting rod 201 and the mounting hole 205, the mounting rod 201 can be fixedly mounted at a suitable position on the door frame with bolts;

[0023] See also Figure 4 and Figure 5, the right side of the fixing plate 601 is fixedly connected to the connection of the stabilizing seat 8, the number of the bosses 603 is two, and both bosses 603 penetrate into the displacement groove 607;

[0024] See also Figure 4 and Figure 5 , the inner wall of the displacement groove 607 is fixedly connected with a spring 606. By setting the spring 606, the displacement plate 605 can be elastically supported, and the displacement plate 605 can be prevented from arbitrarily moving up and down without external force. The other end of the spring 606 is fixedly connected with the displacement plate 605. By setting the displacement plate 605, it can be protruded on the displacement groove 607 to facilitate the staff to drive the displacement plate 605 to move, and meet the fixed installation requirements of the block 608. The displacement plate 605 is fixedly connected with a block 608 on one side close to the boss 603. The surface of the boss 603 is provided with a slot 604 used in conjunction with the block 608. By setting the slot 604 and the block 608, the boss 603 can be prevented from arbitrarily moving and detaching from the fixed plate 601 in the installed state;

[0025] See also Figure 4 and Figure 5 The right end of the boss 603 and the right side of the inner cavity of the fixed plate 601 are fixedly inlaid with a magnetic block 602. By setting the magnetic block 602, when the boss 603 is inserted and installed, it can play the role of magnetic connection, thereby freeing the operator's hands, and the connection between the boss 603 and the fixed plate 601 is in sliding contact.

[0026] When in use, all components are in the initial installation state. According to the specifications, shape and size of the actual door body and door frame, the installation rod 201 and the installation head 5 of appropriate specifications are selected. When the door closer body 1 needs to be fixedly installed, the installation rod 201 is moved so that the damping T block 202 is inserted into the T-slot 203, and then the installation rod 201 is fixedly installed by the bolts in conjunction with the installation holes 205. The installation stability of the door closer body 1 can be ensured by the combination of multiple installation rods 201. When the installation head 5 is installed, the installation head 5 is moved so that the boss 603 enters the displacement slot 607, and the two magnetic blocks 602 contact each other. Magnetic attraction, synchronously pinch the upper and lower displacement plates 605 and exert force to make the displacement plate 605 slide in the displacement groove 607, and the spring 606 is compressed. When the displacement and insertion of the boss 603 is completed, the slot 604 and the block 608 are in an aligned state. At this time, the displacement plate 605 is released and the block 608 is reset and inserted into the slot 604 under the elastic support of the spring 606 to ensure the installation stability of the mounting head 5. The mounting head 5 is fixed in the appropriate position with the bolts. The device adopts an assembled design, which can be well applied to different door bodies and door frames, and the overall operation is quick and convenient, which meets the actual use requirements.

[0027] In summary: the door closer, by providing an assembled mounting mechanism 2, a positioning and anti-slip mechanism 6 and a mounting head 5, solves the problem that the device cannot flexibly change the size of the mounting parts. When applying different door bodies and door frame installation requirements, it is easy for the mounting parts to be too large to fit or too small and the overall stability is average, which has certain restrictive problems.
