Description

Technical Field

[0001] The utility model relates to the technical field of door closer piston structures, in particular to a door closer piston structure. Background Art

[0002] The door closer is completed by the cooperation of the internal mechanical device and the spring. When the door is closed to a certain extent, the mechanical device in the door closer will be activated, releasing the pressure of the spring, causing the movable arm to start rotating. The movable arm drives the connecting pin to move along a certain trajectory to control the closing speed and force of the door. At the same time, the oil flow switch in the oil cylinder will control the closing speed and reduce the impact force through deceleration damping.

[0003] The existing door closer only closes the door during the process of closing the door, but cannot push the door safety outward to lock the door. The internal safety needs to be manually rotated to close, which increases the complexity of use. However, sometimes the user forgets to close the internal safety, resulting in reduced safety. Utility Model Content

[0004] In order to overcome the problem that the existing door closers need to be locked by themselves when closing the door, but sometimes the user forgets to lock the door, which reduces the safety. Furthermore, when the door is locked and needs to be opened, it is too troublesome to use a rotating part to complete the opening and closing of the door, which increases the complexity of use. An embodiment of the present application provides a door closer piston structure, including a door closer body, a piston groove is provided inside the door closer body, a partition plate is fixedly connected to the bottom of the piston groove, a mounting groove is provided at the lower end of the partition plate, a piston is fixedly connected to the middle of the mounting groove, one end of the piston is fixedly connected to a locking rod, a rack is provided on the outer upper end of the piston, and the rack is meshingly connected to a pushing tooth plate.

[0010] In a possible implementation, one end of the pushing tooth plate is fixedly connected to a connecting rod, and one end of the connecting rod is fixedly connected to a pushing column.

[0011] In a possible implementation, one end of the push column is fixedly connected to a spring, one end of the spring is fitted and fixed to a force-bearing plate, and one end of the force-bearing plate is fixedly connected to a lock buckle.

[0012] In a possible implementation, a sliding groove is provided on one side of the inner wall of the piston groove, and the sliding groove is slidably matched with the lock buckle.

[0023] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0024] Embodiment 1:

[0025] This embodiment introduces a specific structure of a door closer piston structure. Figure 1-Figure 4 As shown, the door closer body 1 includes a piston groove 2, a partition plate 3 is fixedly connected to the bottom of the piston groove 2, a mounting groove 4 is provided at the lower end of the partition plate 3, a piston 5 is fixedly connected to the middle of the mounting groove 4, a locking rod 6 is fixedly connected to one end of the piston 5, a rack 20 is provided on the outer upper end of the piston 5, and the rack 20 is meshedly connected to a pushing tooth plate 7;

[0026] When the door needs to be closed, the push tooth plate 7 inside the piston groove 2 inside the door closer body 1 is squeezed inward, and the push tooth plate 7 passes through the matching groove 18 provided inside the partition plate 3, enters the installation groove 4 at the lower end, and meshes with the rack 20 at the upper end of the piston 5, thereby driving the piston 5 to be pushed outward, driving the locking rod 6 fixed at one end to be pushed outward, and then when the door is closed, the locking rod 6 at the lower end automatically locks the door;

[0027] At the same time, when the door is closed, the lock catch 16 is squeezed into the lock mouth. The lock catch 16 contacts the pressure and drives the force plate 15 at one end to move inward, drives the elastic spring 14 at one end to squeeze inward, drives the push column 13 fixedly connected at one end to move, drives the connecting rod 12 fixedly connected at one end to move, drives the push tooth plate 7 to move, and engages with the rack 20 at the upper end of the outside of the piston 5, thereby driving the piston 5 to move outward, drives the locking rod 6 at one end to move outward, and then locks the door and the door frame.

[0028] By adopting the above technical solution:

[0029] With the above design, when the door is closed, the lock catch 16 is squeezed into the lock port, and the lock catch 16 contacts the pressure to drive the force plate 15 at one end to move inward, drive the elastic spring 14 at one end to squeeze inward, drive the push column 13 fixed at one end to move, drive the connecting rod 12 fixed at one end to move, drive the push tooth plate 7 to move, and drive the push tooth plate 7 to pass through the matching groove 18 opened inside the partition plate 3, enter the installation groove 4 at the lower end, mesh with the rack 20 at the upper end of the piston 5, and then drive the piston 5 to be pushed outward, drive the locking rod 6 fixed at one end to be pushed outward, and then when the door is closed, the locking rod 6 at the lower end automatically locks the door.

[0030] Embodiment 2:

[0031] Based on Example 1, this example introduces the specific structure of the piston 5. The piston 5 is provided with a matching rack 8 inside, and a rotating tooth 9 is meshed with the outside of the matching rack 8. One end of the rotating tooth 9 is fixedly connected to a rotating rod 10, and one end of the rotating rod 10 is fixedly connected to a rotating button 11.

[0032] When the door needs to be opened, the rotating knob 11 is rotated to drive the rotating rod 10 at one end, and the rotating rod 10 rotates to drive the rotating tooth 9 at one end to rotate, and the rotating tooth 9 cooperates with the matching rack 8 inside the piston 5, thereby driving the piston 5 to move into the installation groove 4, driving the locking rod 6 at one end to move, and then the locking rod 6 is separated from the door frame and enters the fixed groove 19 opened on one side of the installation groove 4;

[0033] Furthermore, when the piston 5 moves inwardly, the rack 20 at the upper end of the piston 5 engages with the pushing tooth plate 7, thereby driving the pushing tooth plate 7 to move inwardly, driving the connecting rod 12 at one end to shrink inwardly, driving the pushing column 13 at one end to shrink inwardly, driving the elastic spring 14 at one end to shrink inwardly, driving the force plate 15 at one end to shrink inwardly, and driving the lock buckle 16 at one end to shrink inwardly and separate from the door frame, thereby opening the door.

[0034] The user's operation steps are:

[0035] S1. When the door is closed, the lock catch 16 is squeezed into the lock port. The lock catch 16 contacts the pressure and drives the force plate 15 at one end to move inward, drives the elastic spring 14 at one end to squeeze inward, drives the push column 13 fixed at one end to move, drives the connecting rod 12 fixed at one end to move, drives the push tooth plate 7 to move, and through the installation groove 4 at the lower end of the partition plate 3, it meshes with the rack 20 at the upper end of the piston 5, and then drives the piston 5 to be pushed outward, drives the lock rod 6 fixed at one end to be pushed outward, and then when the door is closed, the lock rod 6 at the lower end automatically locks the door, and then the lock catch 16 and the lock rod 6 lock the door at the same time;

[0036] S2. When the door needs to be opened, the rotating knob 11 is rotated to drive the rotating rod 10 at one end. The rotating rod 10 rotates to drive the rotating tooth 9 at one end to rotate, and the rotating tooth 9 cooperates with the matching rack 8 inside the piston 5, thereby driving the piston 5 to move into the installation groove 4, driving the locking rod 6 at one end to move, and then the locking rod 6 is separated from the door frame and enters the fixed groove 19 opened on one side of the installation groove 4;

[0037] S3. When the piston 5 moves inward, the rack 20 at the upper end of the piston 5 engages with the pushing tooth plate 7, thereby driving the pushing tooth plate 7 to move inward, driving the connecting rod 12 at one end to shrink inward, driving the pushing column 13 at one end to shrink inward, driving the elastic spring 14 at one end to shrink inward, driving the force plate 15 at one end to shrink inward, driving the lock buckle 16 at one end to shrink inward and separate from the door frame, thereby opening the door.

[0038] By adopting the above technical solution:

[0039] According to the above design, when the door needs to be opened, the rotating knob 11 is rotated to drive the rotating rod 10 at one end to rotate, thereby driving the rotating tooth 9 at one end to rotate, and cooperating with the matching rack 8 inside the piston 5, thereby driving the piston 5 to move into the installation groove 4, driving the locking rod 6 at one end to move, and then the locking rod 6 is separated from the door frame and enters the fixed groove 19 opened on one side of the installation groove 4. When the piston 5 moves inward, the rack 20 at the upper end of the piston 5 engages with the pushing tooth plate 7, thereby driving the pushing tooth plate 7 to move inward, driving the connecting rod 12 at one end to retract inward, driving the pushing column 13 at one end to retract inward, driving the elastic spring 14 at one end to retract inward, driving the force plate 15 fitted at one end to retract inward, and driving the lock buckle 16 at one end to retract inward and separate from the door frame, thereby opening the door.

[0040] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
