Looking at Patent No. 10-1422086, the center bracket (400) for fixing a fire sprinkler (200) used to fix the fire sprinkler to a support frame is composed of a cam projection pressing part (440) in which a cam lever (446) is formed so that the sprinkler can be fixed in a state where the sprinkler (200) is fitted into the support frame and the cam projection can be rotated and fastened into the center bracket groove (412, 412').

[0008] The center bracket (400) has center bracket grooves (412, 412') formed on the center bracket bending surfaces (411, 411'), respectively, so that the spring cleaner (200) can be fastened by pressing the cam projection by the rotation of the cam lever (446) while the center bracket is fitted into the center bracket grooves (412, 412').

[0009] The cam protrusion pressing part (440) mounted on the center bracket (400) has a pin hole formed on one edge for fixing the cam lever, and is fixed in a state where a hinge pin (450) is inserted.

[0010] In another embodiment, the center bracket for fixing the fire sprinkler has a contact piece (420) formed between the sprinkler and the cam protrusion pressurizing part (440). A 'C'-shaped bent surface (411, 411') is formed so that the sprinkler (200) can be fixed in a state where a support frame used to connect the center bracket (400) to the sprinkler (200) is fitted, and a center bracket bending groove (413) is formed between the center bracket bending surfaces (411, 411'), and the sprinkler (200) is formed so that it can be connected by the contact piece (420) in a state where the sprinkler (200) is fitted into the center bracket groove (412, 412'). A center bracket (400) is formed in which center bracket grooves (412, 412') are formed on the center bracket bending surfaces (411, 411'), a pin hole for fixing a contact piece is formed on the lower part of the center bracket (400) so that a hinge pin (430) can be inserted and fixed, and a pin hole for fixing a cam lever is formed on one edge of the center bracket (400) so that a hinge pin (450) can be inserted and fixed.

[0011] The main body is formed in a curved shape so that the body of the sprinkler (200) can become the center bracket while being embedded in the center bracket bending groove (413), and a contact piece groove is formed on the inner side of the main body so that the body of the sprinkler (200) can be fixed, and a pin hole is formed at one end of the main body so that a hinge pin can pass through, and the hinge pin passes through the pin hole of the contact piece (420) and the hinge pin is fixed in the pin hole of the center bracket (400) so that the contact piece (420) is combined with the center bracket (400) and the contact piece (420) is formed to rotate with the hinge pin as the center axis of rotation.

[0012] The center bracket (400) has 'U'-shaped bent surfaces (411, 411') formed so that the sprinkler (200) can be clamped with a support frame inserted to connect the center bracket to the sprinkler (200), and a center bracket bending groove (413) is formed between the center bracket bending surfaces (411, 411'), and center bracket grooves (412, 412') are formed on the center bracket bending surfaces (411, 411') respectively so that the sprinkler (200) can be clamped by the cam projection pressing part (440) with the sprinkler (200) inserted into the center bracket grooves (412, 412'), and a pin hole for fixing the cam lever is formed on one edge of the center bracket (400) respectively so that the hinge pin (450) can be fixed with the hinge pin (450) inserted. there is.

[0013] In addition, a center bracket for a fire sprinkler developed by the inventor is known as Patent No. 10-2094897, in which a center bracket with a cam lever anti-loosening rocker (300) is combined.

[0014] The conventional center bracket is fitted into and connected to a support frame, and center bracket grooves are formed on the upper and lower sides of the bent surface, respectively, so that the sprinkler can be clamped. In addition, the conventional center bracket has a center bracket door that is rotatably connected to one edge of the center bracket by a hinge pin, and a connecting groove is formed so that a center bracket space of the sprinkler body is provided by combining with the center bracket groove of the center bracket.

[0015] Conventional center brackets have a problem in that the center bracket and the center bracket door cannot be quickly and easily connected because the center bracket door does not slide to the opposite side of the rotational connection point while rotating around the rotational connection point of the hinge pin. In addition, conventional center brackets have a problem in that the fastening groove of the center bracket door must be formed with a structure that is open to one side because the center bracket door does not slide to the opposite side of the rotational connection point while rotating around the rotational connection point of the hinge pin.

[0016] In addition, conventional center brackets have a structure in which the fastening groove of the center bracket door is open to one side, so there is a problem in that the connection between the center bracket and the center bracket door separates or breaks when strong torque is applied.
