The center support of doors and windows is a component installed in the square frame or fan frame and plays a central supporting role, that is, it refers to the component between the middle part of the door and window frame. For example, in the Japanese window type, the middle horizontal bar is the center support, and in the field window type, the cross horizontal bar and vertical bar are the center support. The center support strengthens the hardness of the aluminum door and window frame and installs and connects the glass. When assembling aluminum alloy window frames, most of them require connectors to connect two adjacent center supports or center supports and outer frames. The connectors currently on the market have the following main shortcomings: (1) When installing the connector, it is necessary to pass it through the groove from both ends of the profile, which is less convenient for installation; (2) When fixing the connector, it is necessary to punch holes in the profile. On the one hand, the position accuracy of the holes is required to be high, and on the other hand, the sealing of aluminum alloy is poor. Summary of the invention

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings.

[0022] A glue-injected center support outer connecting piece is used to connect adjacent center supports 3 or adjacent center supports 3 and outer frames. The center support outer connecting piece includes a buckle 1 and a fixing screw 2. The fixing screw 2 is installed in the buckle 1 through a thread. The buckle 1 is buckled on the center support 3, and the fixing screw 2 abuts against the outer side of the center support 3. The buckle 1 is acted upon by the fixing screw 2, thereby increasing the friction force of the center support outer connecting piece and the center support 3 at the contact portion, thereby locking the buckle 1 and the center support 3.

[0023] When installing the glue-injected center support external connection part, there is no need to install the fastener 1 into the slot 3-1 of the center support 3 from both ends of the profile. The fastener 1 can be directly installed on the center support 3 according to the installation requirements, and then the fastener 1 can be locked by the fixing screw 2.

[0024] A hook plate 1-5 is provided at the bottom of the fastener 1, and a groove 1-6 is provided on the hook plate 1-5, so that the end of the hook plate 1-5 forms a hook portion 1-1; a snap plate 1-12 is provided on one side wall of the fastener 1, so that a snap portion 1-2 is formed on one side of the fastener 1; the hook portion 1-1 and the snap portion 1-2 are combined to form a connecting structure, and the fastener 1 is snapped on the middle support 3 through the connecting structure.

[0025] During installation, the hook plate 1-5 of the fastener 1 is hooked into the slot 3-1 of the center support 3, and then the fastener 1 is rotated so that the hook plate 1-12 is engaged in another slot 3-1 of the center support 3, thereby realizing the assembly of the fastener 1 and the center support 3.

[0026] A glue injection baffle 1-3 is also provided on one side wall of the fastener 1. The glue injection baffle 1-3, the hook portion 1-1 and the outer side wall of the middle support 3 together form a glue injection cavity 4. Preferably, the glue injection baffle 1-3 and the fastening plate 1-12 are located on the same side of the fastener 1, so that a glue injection cavity 4 for glue injection is formed in the connecting structure to ensure that the waterproof performance of the aluminum alloy frame meets the requirements after assembly.

[0027] On one side of the fastener 1, there is a concave end surface 1-4 parallel to the side wall of the fastener 1. The fastener 1 and the glue injection baffle 1-3 are respectively arranged on the concave end surface 1-4, so as to appropriately increase the length of the fastening plate 1-12, so that the fastening part 1-2 undergoes a certain elastic deformation during the fastening process, thereby facilitating the fastening of the fastening part 1-2 with the center support 3.

[0028] The fastener 1 is a hollow part, with a mounting through hole 1-8 on the top and screw holes 1-7 on the bottom. The screw holes 1-7 and the mounting through holes 1-8 are coaxially arranged, and the fixing screw 2 is installed in the screw hole 1-7 through the mounting through hole 1-8. The fixing screw 2 can also be rotated and adjusted through the mounting through hole 1-8.

[0029] A reinforcing rib 1-9 is provided in the middle of the fastener 1, and a connecting cavity 1-10 is formed between the reinforcing rib 1-9 and the inner wall of the fastener 1, so that the subsequently installed middle support or outer frame can be connected to the connecting cavity 1-10 by screws, thereby improving the installation stability of the subsequently installed middle support or outer frame.

[0030] In order to facilitate the adjustment of the fixing screw 2, a connecting hole 1-11 is provided on the reinforcing rib 1-9, and the connecting hole 1-11 is adapted to the mounting through hole 1-8, that is, the diameter of the connecting hole 1-11 is consistent with the diameter of the mounting through hole 1-8, and they are coaxially arranged.

[0031] A hexagonal slot is provided at the upper end of the fixing screw 2 to facilitate the hexagonal wrench to rotate the fixing screw 2. A butt joint 2-1 is provided at the lower end of the fixing screw 2. The diameter of the butt joint 2-1 is smaller than the diameter of the fixing screw 2 to facilitate the connection between the butt joint 2-1 and the middle support 3.
