Description

Technical Field

[0001] This utility model relates to the field of metal door and window technology, and in particular to a metal door and window connection device. Background Technology

[0002] Metal doors and windows are made of metals such as aluminum alloy or stainless steel. Currently, most metal doors and windows on the market have complicated connections, and installers need to use installation tools to assemble the equipment, resulting in slow assembly efficiency.

[0003] Utility model patent CN216341709U discloses a connection structure for metal doors and windows. During assembly, the central column is inserted obliquely into the upper two connecting devices. After the central column is engaged in the upper connecting devices, it is pushed upwards to make it vertical, and then pushed downwards to engage in the lower connecting device. After fixing the position of the central column, the limiting bracket is pulled. The limiting bracket then experiences force and displacement, engaging the central column and the stop block during displacement. Subsequently, the stop block is pushed, and the stop block applies pressure to the limiting spring. When the force is applied, the limiting spring deforms, and the locking block loses its constraint and shifts. The restraint frame then rotates, causing the rotating block to rotate as well. When the restraint frame reaches its predetermined position, it engages with the limiting frame, releasing the locking block. Simultaneously, the limiting spring, freed from constraint, rebounds, causing the locking block to reset. During this reset, the locking block engages with both the rotating block and the restraint frame, fixing their positions. This completes the assembly of the equipment. The connection device facilitates the assembly of the equipment.

[0004] The above solution facilitates equipment assembly by setting up a connecting device, but it is not convenient to install door and window glass inside the outer frame, making it not very practical. Utility Model Content

[0005] The purpose of this utility model is to provide a metal door and window connection device, which solves the problem that it is inconvenient to install door and window glass inside the outer frame and has low practicality.

[0006] To achieve the above objectives, this utility model provides a metal door and window connection device, including an outer frame and an installation assembly; the installation assembly includes a U-shaped mounting bracket, a spring, and a strip-shaped abutment bracket. The inner side of the U-shaped mounting bracket has a first mounting groove, and the upper and lower ends of the U-shaped mounting bracket are rotatably connected to the outer frame, respectively. The U-shaped mounting bracket is located inside the outer frame, and the side of the outer frame has an installation cavity. The two ends of the spring are fixedly connected to the strip-shaped abutment bracket and the outer frame, respectively. The spring is located inside the installation cavity, and the strip-shaped abutment bracket is slidably connected to the outer frame. The end of the strip-shaped abutment bracket away from the spring has a second mounting groove.

[0007] The U-shaped mounting bracket has fixed shafts at its upper and lower ends, and the inner side of the outer frame has circular grooves at its upper and lower ends, with the fixed shafts located inside the circular grooves.

[0008] The mounting assembly further includes a locking screw, which is threaded to the outer frame and passes through the outer frame. The U-shaped mounting bracket has a fixing opening.

[0009] The mounting assembly further includes multiple plugs, which are slidably connected to the outer frame. The multiple plugs are spaced vertically on the outer frame, and the strip-shaped support frame is provided with multiple insertion ports corresponding to the plugs.

[0010] The mounting assembly further includes a connecting frame, a connecting piece, and a tension spring. The outer frame has a placement groove, and multiple bolts are fixedly connected to the connecting frame. The connecting piece is fixedly connected to the connecting frame, and the tension spring has two ends.

[0011] This utility model discloses a metal door and window connection device. When installing door and window glass, firstly, the U-shaped mounting bracket is rotated to misalign with the outer frame. The door and window glass is then inserted into the first mounting groove through the open end of the U-shaped mounting bracket, thus fixing the door and window glass in the U-shaped mounting bracket. Next, the strip-shaped abutment bracket is pressed, causing it to move into the mounting cavity, allowing the U-shaped mounting bracket to rotate until it coincides with the outer frame. Then, the strip-shaped abutment bracket is released, and under the support of the spring, it moves towards the U-shaped mounting bracket, causing one side of the door and window glass to engage in the second mounting groove. The periphery of the door and window glass is fixed to the inner side of the outer frame under the combined action of the strip-shaped abutment bracket and the U-shaped mounting bracket. This facilitates the installation of door and window glass and solves the problem of inconvenience in installing door and window glass inside the outer frame, resulting in low practicality.

Detailed Implementation

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] Please see Figures 1 to 3 , Figure 1 This is a structural schematic diagram of a metal door and window connection device according to this utility model. Figure 2 This is a structural cross-sectional view of a metal door and window connection device according to this utility model. Figure 3 This utility model relates to a metal door and window connection device. Figure 2 Sectional view at point AA.

[0019] This utility model provides a metal door and window connection device, including an outer frame 100 and an installation component. The installation component includes a U-shaped mounting bracket 210, a spring 220, a strip-shaped support bracket 230, a locking screw 240, multiple plugs 250, a connecting bracket 260, a connecting piece 270, and a tension spring 280.

[0020] In this specific embodiment, the U-shaped mounting bracket 210 has a first mounting groove 211 on its inner side. The upper and lower ends of the U-shaped mounting bracket 210 are rotatably connected to the outer frame 100, and the U-shaped mounting bracket 210 is located inside the outer frame 100. The side of the outer frame 100 has a mounting cavity 110. The two ends of the spring 220 are fixedly connected to the strip-shaped support bracket 230 and the outer frame 100, respectively. The spring 220 is located inside the mounting cavity 110. The strip-shaped support bracket 230 is slidably connected to the outer frame 100. The end of the strip-shaped support bracket 230 away from the spring 220 has a second mounting groove 231. The U-shaped mounting bracket 210 is rotatable relative to the outer frame 100. The spring 220 supports the strip-shaped abutment bracket 230. When the U-shaped mounting bracket 210 rotates to the point where its outer side is in contact with the inner side of the outer frame 100, the strip-shaped abutment bracket 230 can contact one end of the opening of the U-shaped mounting bracket 210 under the support of the spring 220, so that the U-shaped mounting bracket 210 and the strip-shaped abutment bracket 230 form a rectangle. The first mounting groove 211 of the U-shaped mounting bracket 210 and the second mounting groove 231 of the strip-shaped abutment bracket 230 are both used to place door and window glass. When installing window or door glass, first rotate the U-shaped mounting bracket 210 to misalign it with the outer frame 100. Insert the window or door glass into the first mounting groove 211 through the open end of the U-shaped mounting bracket 210, thereby fixing the window or door glass in the U-shaped mounting bracket 210. Then, press the strip-shaped abutment bracket 230 to move it into the mounting cavity 110, allowing the U-shaped mounting bracket 210 to rotate until it coincides with the outer frame 100. Then, the strip-shaped support bracket 230 is released, and the strip-shaped support bracket 230 moves towards the U-shaped mounting bracket 210 under the support of the spring 220, so that one side of the window glass is engaged into the second mounting groove 231. The periphery of the window glass is fixed to the inner side of the outer frame 100 under the combined action of the strip-shaped support bracket 230 and the U-shaped mounting bracket 210, which facilitates the installation of the window glass and solves the problem that it is inconvenient to install the window glass inside the outer frame 100 and the practicality is not high.

[0021] Furthermore, the U-shaped mounting bracket 210 is provided with fixed shafts 212 at its upper and lower ends, and the inner side of the outer frame 100 has circular grooves 120 at its upper and lower ends, with the fixed shafts 212 located inside the circular grooves 120. The fixed shafts 212 are able to rotate inside the circular grooves 120, and the fixed shafts 212 and the circular grooves 120 cooperate with each other to realize the rotational connection between the U-shaped mounting bracket 210 and the outer frame 100.

[0022] Specifically, the locking screw 240 is threadedly connected to the outer frame 100, and the locking screw 240 passes through the outer frame 100. The U-shaped mounting bracket 210 has a fixing opening 213. The locking screw 240 can rotate relative to the outer frame 100. When the U-shaped mounting bracket 210 rotates to coincide with the outer frame 100, the locking screw is tightened. At this time, the locking screw can extend into the fixing opening 213, making the U-shaped mounting bracket 210 unable to rotate relative to the outer frame 100, thereby fixing the U-shaped mounting bracket.

[0023] The plurality of bolts 250 are slidably connected to the outer frame 100, and are spaced vertically on the outer frame 100. The strip-shaped support frame 230 has multiple insertion slots 232 corresponding to the bolts 250. The bolts 250 can slide relative to the outer frame 100, and can be inserted into the insertion slots 232, thereby fixing the strip-shaped support frame 230 and preventing it from sliding relative to the outer frame 100, thus improving the stability of the door and window glass.

[0024] Additionally, the outer frame 100 has a placement groove 130, and the plurality of plugs 250 are fixedly connected to the connecting frame 260. The connecting piece 270 is fixedly connected to the connecting frame 260, and the two ends of the tension spring 280 are fixedly connected to the outer frame 100 and the connecting piece 270, respectively. The tension spring 280 is located inside the placement groove 130. The connecting frame 260 is used to connect the plugs 250, the connecting piece 270 is used to connect the connecting frame 260, and the tension spring 280 is used to connect the connecting piece 270. The tension spring 280 pulls the connecting piece 270, so that each plug 250 is inserted into the socket 232 without external force, thereby fixing the strip-shaped support frame 230. When it is necessary to move the strip support frame 230, pull the connecting piece 270 to move the connecting frame 260, thereby causing each of the plugs 250 to move out of the socket 232, so that the strip support frame 230 can be pressed to move the strip support frame 230.

[0025] When installing window and door glass using a metal door and window connecting device, first rotate the U-shaped mounting bracket 210 to misalign it with the outer frame 100. Insert the window and door glass into the first mounting groove 211 through the open end of the U-shaped mounting bracket 210, thereby fixing the window and door glass in the U-shaped mounting bracket 210. Then pull the connecting piece 270 to move the connecting bracket 260, thereby moving each of the bolts 250 out of the socket 232. Press the strip-shaped abutment bracket 230 to move it into the mounting cavity 110, allowing the U-shaped mounting bracket 210 to rotate to coincide with the outer frame 100. Then release the strip-shaped abutment bracket 230. Under the resistance of the spring 220, the glass moves towards the U-shaped mounting bracket 210, causing one side of the window glass to engage in the second mounting groove 231. The connecting piece 270 is released, and the bolt 250 is reset under the action of the tension spring 280, causing the end of the bolt 250 away from the connecting bracket 260 to be inserted into the socket 232, thereby fixing the strip support bracket 230. The locking screw 240 is tightened, causing the end of the locking screw 240 to extend into the fixing port 213, thereby fixing the U-shaped mounting bracket 210. Under the combined action of the strip support bracket 230 and the U-shaped mounting bracket 210, the periphery of the window glass is fixed to the inner side of the outer frame 100, facilitating the installation of the window glass.

[0026] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art will understand that all or part of the processes for implementing the above embodiments and equivalent variations made in accordance with the claims of this application are still within the scope of this application.
