[0025] In this embodiment, hydraulic buffer shaft 23 includes connecting head, hydraulic telescopic rod and spring, and the end of lock tongue 22 is connected with connecting head rotation through second pivot 26, and connecting head is fixedly connected with one end of hydraulic telescopic rod, and the other end of hydraulic telescopic rod is connected with base 21 rotation through third pivot 27, and one end of spring is connected with connecting head, and the other end of spring is connected with the other end of hydraulic telescopic rod.

[0026] The working principle of the embodiment is as follows: in use, the door stop base 2 is vertically installed on the door leaf, and the door stop head 1 is installed on the ground; when the door stop base 2 and the door stop head 1 are locked or unlocked, the door stop head 1 drives the lock tongue 22 to rotate relative to the first rotating shaft 25 under the interaction of the door stop head 1 and the door stop base 2; at this time, the second rotating shaft 26 rotates around the first rotating shaft 25, so that the hydraulic buffer shaft 23 rotates around the third rotating shaft 27 while being stretched and contracted, thereby playing a buffering role; since the end of the second rotating shaft 26 is in sliding fit with the waist-shaped groove 241, the outer shell 24 will rotate around the third rotating shaft 27 together with the hydraulic buffer shaft 23 while the second rotating shaft 26 rotates around the first rotating shaft 25, which helps to reduce the overall volume of the door stop base 2, i.e., the space occupied by the door stop base 2 can be reduced; when the door stop base 2 is assembled, the lock tongue 22 and the hydraulic buffer shaft 23 are first installed on the base 21 through the first rotating shaft 25, the second rotating shaft 26 and the third rotating shaft 27, then the position of the outer shell 24 is adjusted, the end of the second rotating shaft 26 is embedded in the waist-shaped groove 241 through the first mounting groove 242 (the end of the second rotating shaft 26 enters the first mounting groove 242 from the bottom end of the first mounting groove 242 and then moves to the waist-shaped groove 241 through the top end of the first mounting groove 242), and then the position of the outer shell 24 is adjusted again, the end of the third rotating shaft 27 is embedded in the second mounting groove 243 through the bottom end of the second mounting groove 243, so that the assembly of the door stop base 2 is completed, the structure is simple, no connecting pieces such as bolts are needed, and the door stop base 2 is easy to disassemble and assemble.

[0027] For example, the axis of the waist-shaped groove 241 is parallel to the first line segment 3, the first line segment 3 is the line connecting the axis of the first rotating shaft 25 and the axis of the second rotating shaft 26, and the first rotating shaft 25 will not be blocked by the waist-shaped groove 241 during rotation, thereby ensuring the normal operation of the door stop base 2; in this embodiment, the first mounting groove 242 is arranged perpendicularly to the waist-shaped groove 241, which facilitates the assembly and disassembly of the end of the first rotating shaft 25 and the first mounting groove 242.

[0028] For example, the base 21 is provided with a limiting groove 211 with an open top on each side; when the door stop head 1 and the door stop base 2 are not locked, the end of the second rotating shaft 26 is matched with the limiting groove 211, specifically, the bottom of the end of the second rotating shaft 26 is matched with the bottom of the limiting groove 211; the base 21 is provided with a limiting block 212; when the door stop head 1 and the door stop base 2 are locked, the lock tongue 22 abuts against the limiting block 212; the limiting groove 211 and the limiting block 212 can limit the swing amplitude of the lock tongue 22 and prevent the lock tongue 22 from rotating excessively.

[0029] Exemplarily, two sides of the base 21 are respectively provided with an arc-shaped slot 213 arranged around the axis of the third rotating shaft 27, and the shell 24 is provided with an arc-shaped portion, when the door stopper 1 is not locked with the door stopper base 2, the arc-shaped portion cooperates with the arc-shaped slot 213, facilitating the positioning assembly of the shell 24 and the base 21, and the arc-shaped portion can rotate around the axis of the third rotating shaft 27 relative to the arc-shaped slot 213, ensuring that the shell 24 can rotate together with the hydraulic buffer shaft 23 around the third rotating shaft 27.

[0030] Exemplarily, the bottom of the base 21 is provided with a sliding slot 214 with at least one open end, and the sliding slot 214 is slidably connected with a mounting block 28, the bottom surface of the mounting block 28 is flush with the bottom surface of the base 21, the mounting block 28 is provided with a mounting hole 281, and the side of the base 21 is threadedly connected with a locking bolt 282, the end of the locking bolt 282 abuts against the side of the mounting block 28, when the door stopper base 2 is installed, the mounting block 28 is first installed and fixed on the door leaf, then the position of the base 21 is adjusted, so that the open end of the sliding slot 214 is aligned with the mounting block 28, then the mounting block 28 is relatively embedded into the sliding slot 214, and finally the locking bolt 282 is tightened, so that the installation of the door stopper base 2 is completed, after the locking bolt 282 is loosened, the base 21 can slide relative to the mounting block 28, so that the position of the base 21 can be adjusted.

[0031] Exemplarily, the bottom of the second mounting slot 243 is provided with an expanding portion gradually expanding towards the bottom end of the second mounting slot 243, so that the end of the third rotating shaft 27 is embedded into or separated from the second mounting slot 243.

[0032] Exemplarily, the end of the base 21 extending out of the locking tongue 22 is provided with a clamping slot 221, one side of the clamping slot 221 forms a contact portion 222, and the other end of the clamping slot 221 forms a stop portion 223, the door stopper 1 comprises a fixed seat 11 and a push rod 12 arranged on the fixed seat 11, the push rod 12 matches with the clamping slot 221, as shown in Figure 8 the drawing, when in use, the door stopper base 2 is vertically fixed on the door leaf, it can be understood that at this time the stop portion 223 is higher than the contact portion 222, and the door stopper 1 is fixed on the ground, when locked, the door stopper base 2 gradually approaches the door stopper 1, the push rod 12 gradually enters the clamping slot 221 through the stop portion 223, then the push rod 12 acts on the contact portion 222, thereby relatively driving the locking tongue 22 to rotate, until the push rod 12 cooperates with the clamping slot 221, realizing the locking of the door stopper base 2 and the door stopper 1; when unlocked, the push rod 12 relatively pulls the stop portion 223 to rotate the locking tongue 22, until the push rod 12 separates from the clamping slot 221, realizing the unlocking of the door stopper base 2 and the door stopper 1.

[0033] The above merely is the preferred implementation form of the present application, and it should be noted that, for the ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and substitutions can be made, and these improvements and substitutions should also be considered as the protection scope of the present application.
