[0019] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "up", "down", "left" and "right" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0021] In the embodiment of the present invention, "and / or" is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0022] Reference example Figure 1 , Figure 2 , an adjustable stainless steel door closer rocker arm, comprising a main rocker arm 1, the main rocker arm 1 is provided with a rotatable auxiliary rocker arm 2, the auxiliary rocker arm 2 is provided with a plurality of limiting through holes 21 from left to right, the auxiliary rocker arm 2 is provided with a retractable telescopic plate 3, the telescopic plate 3 is provided with a plurality of positioning holes 31 from left to right, the positioning hole 31 is provided with a fastener 4, and is slidably arranged in the limiting through hole 21, the fastener 4 is provided with a hexagonal groove 41, and the outer wall of the fastener 4 is also provided with an anti-slip groove 42. By arranging the positioning holes 31 in different limiting through holes 21, the telescopic range of the adjustable telescopic plate 3 is greatly increased. If, because the fastener 4 is not firmly fixed, the fastener 4 cooperates with the limiting through hole 21 to make the telescopic plate 3 move only within its small range, the conventional adjustable door closer rocker arm is prevented from being loosened due to the position of the screw used to adjust the length during long-term use, resulting in a large change in the adjusted length, which causes the door closer rocker arm to be unable to be used normally;

[0023] It is worth mentioning that the telescopic plate 3 is provided with a mounting bracket 5 that can rotate left and right, and the mounting bracket 5 is provided with a mounting hole 51, and a fastening screw or a fastening bolt is passed through the mounting hole 51 to connect and fix the mounting bracket 5 to the door body;

[0024] It is worth mentioning that the main rocker arm 1 is provided with a cylinder 11, the auxiliary rocker arm 2 is sleeved on the cylinder 11 and rotates with the cylinder 11 as the axis. The main rocker arm 1 is also provided with a fixed sleeve 12, and a square through hole 13 is provided in the fixed sleeve 12. The cylinder 11 is used in conjunction with the auxiliary rocker arm 2. The fixed sleeve 12 is sleeved on the oil tank, and the square through hole 13 prevents the main rocker arm 1 from rotating.

[0025] It is worth mentioning that the main rocker arm 1, the auxiliary rocker arm 2, and the telescopic plate 3 are provided with a plurality of adjustment marks 6 from left to right. The adjustment mark 6 is a straight line with arrows at both ends of the straight line. The adjustment mark 6 helps the user know the rotation direction of the main rocker arm 1 and the auxiliary rocker arm 2;

[0026] It is worth mentioning that the auxiliary rocker arm 2 is provided with a slide groove 22 for the telescopic plate 3 to move, and the slide groove 22 provides a guiding function for the telescopic plate 3;

[0027] It is worth mentioning that the fastener 4 is configured as a screw, and the anti-slip groove 42 facilitates the user to rotate the fastener 4, thereby fixing the telescopic plate 3 in the position after the activity. In order to ensure a more stable connection, an Allen wrench can also be inserted into the hexagonal groove 41 to tighten the fastener 4 tightly, and the head of the fastener 4 is pressed tightly against the auxiliary rocker arm 2.

[0028] The above design scheme can enable the product to achieve the advantages of adjustable telescopic distance and convenient adjustment.

[0029] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
