Description

Technical Field

[0001] The utility model relates to the assembly of metal doors, and particularly to a bead structure of a combined window Background Art

[0002] Aluminum alloy doors with glass windows are commonly used in scenarios such as laboratories and hospitals. Traditional manufacturers mostly use welding or rivets to fix the glass window beads of steel fire doors. If welding is used, there will be weld seams between the beads and the door panels. There are multiple rivets on the beads when using rivets, which will greatly affect the aesthetics. Moreover, during the installation process, welding or riveting is required, and the efficiency is very low.

[0003] At present, Chinese Patent No. CN215718205U discloses a steel glass bead structure and its installation structure, belonging to the technical field of doors and windows with windows. A novel steel glass bead structure includes a bead. One end of the cross-section of the bead has a 180° flanging structure, and the other end is in the shape of a U-shaped groove. By adopting a 180° turned dead edge structure for the overlapping surfaces of the bead with the door leaf and the glass side, the utility model effectively avoids the scalding phenomenon during the front welding of the special plate bead group welding; effectively avoids the welding damage to the plate when prying the screws.

[0004] The above existing technical solutions have the following defects: Although the scalding caused by welding is avoided through the cooperation of screws and bolts, the screws and bolts still affect the flatness of the surface of the window bead, which has a certain impact on the overall aesthetics, and multiple screws need to be tightened on both sides of the door body during installation, resulting in low efficiency. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a bead structure of a combined window to solve the problems existing in the above existing technology.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions:

[0007] A bead structure of a combined window includes a door body, a first bead, a second bead, and a transparent window. An observation groove is provided on the door body. A plurality of positioning grooves are symmetrically arranged on the left and right sides of the observation groove. Limit buckles are provided on both the inner top and inner bottom of the positioning groove. A first bead is provided at the front end of the observation groove, a second bead is provided at the rear end of the observation groove. A plurality of positioning buttons are symmetrically arranged on both sides of the first bead and the second bead. The positioning buttons correspond to the positions in the positioning grooves one by one. A transparent window is provided between the first bead and the second bead.

[0008] By adopting the above technical solution, there is no need to use welding, riveting and other connection methods, nor is there a need to rely on bolt connection methods to firmly fix the molding on the door. The positioning buckles on both sides of the molding can cooperate with the positioning grooves. The molding only needs to be placed in the corresponding position and then tapped downward. The positioning buckle is deformed by the force and is sleeved on the limit buckle to form a clamping fixation with the limit buckle. Through the first molding and the second molding on the front and back sides, the transparent window made of glass can be fixed therein.

[0009] In a further embodiment, the first pressure strip and the second pressure strip both include a top piece and a bottom piece, a first through slot is provided at a top middle position of the top piece, an upper end periphery of the first through slot is provided with a slope, the top circumference of the slope is smaller than the bottom circumference, a second through slot is provided at a middle position of the bottom piece, the size of the second through slot is the same as the bottom of the slope, and the bottom of the slope is fixedly connected to the top of the bottom piece.

[0010] By adopting the above technical solution, the top piece is used to cooperate with the top of the door body to keep the pressure strip in this horizontal position and will not slide into the observation groove, while the bottom piece is used to press and fix the transparent window. Through the cooperation of the first and second pressure strips on both sides, it can be ensured that the transparent window is fixed and cannot move at will, and the positioning buckle is set at the bottom of the periphery of the top piece, corresponding one by one to the positioning groove on the side wall of the observation groove.

[0011] In a further embodiment, positioning buckles are provided on both left and right sides of the bottom of the top piece, the top of the positioning buckle is fixedly connected to the bottom of the top piece, a third through slot is provided on the positioning buckle, a connecting ear with the same shape as the third through slot is fixedly connected to the outer side of the positioning buckle, and the top of the connecting ear is open.

[0012] By adopting the above technical solution, when the pressure strip is pushed into the observation slot, the positioning buckle will be deformed to a certain extent under the action of force and slide into the positioning slot, and then restore its original shape due to the elasticity of the material itself. At this time, the top opening of the connecting ear on the positioning buckle forms a snap connection with the limiting buckle, and the pressure strip is fixed.

[0013] In a further embodiment, a transparent window is provided at the bottom of the bottom end piece, and snap-fitting pieces are provided between the transparent window and a plurality of side walls of the observation slot, and the transparent window is bonded and fixed to the door body.

[0014] By adopting the above technical solution, in order to facilitate the setting and play a shock-absorbing role, a certain gap is provided between the transparent window made of glass and the side wall of the observation slot. By inserting the clip made of flexible material into this gap, the transparent window can be protected. After the setting is completed, a circle of foam glue needs to be squeezed into the gap to ensure that the transparent window does not move when the door is opened.

[0015] In a further embodiment, the positioning groove is provided with latching teeth at the upper and lower ends, and the latching teeth are provided with latching grooves on the left and right sides.

[0016] By adopting the above technical solution, the latch teeth can cooperate with the limiting buckle to limit the positioning buckle, and the slots on the left and right sides can prevent the positioning buckle from scratching the door body when sliding into the positioning slot, or causing damage in a collision to affect the performance of the material itself.

[0017] In a further embodiment, a door handle is provided at intervals below the observation slot.

[0018] In a further embodiment, a receiving groove is spaced apart below the door handle, and a mechanical lock is fixedly installed in the receiving groove.

[0019] By adopting the above technical solution, the door handle and the mechanical lock can cooperate with each other, and when the mechanical lock is locked, the door cannot be opened by twisting the door handle.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. Through the arrangement of the positioning buckle and the positioning groove, the positioning buckle can be squeezed into the positioning groove with the help of a certain degree of deformation during the pressing process. After being squeezed into the positioning groove, the positioning buckle returns to its original state and is clamped and fixed with the positioning groove. This installation method is simple and fast, and the pressure strip can be directly fixed on the door body, which can speed up the installation speed and increase the overall aesthetics of the pressure strip and the door;

[0022] 2. Through the arrangement of the bottom end piece and the inclined surface, the transparent window can be fixed by the bottom end piece, and the inclined surface can be used to cover the part where the window and the side wall of the observation slot are fixed by the foam glue, thereby increasing the aesthetics;

[0023] 3. By setting the clamping parts, the vibration caused by the contact between the transparent window and the door body can be reduced after the installation is completed. During the installation, the transparent window can be initially fixed, which is convenient for the subsequent use of foam glue to squeeze into the gap for bonding and fixing.

A transparent window 4 is arranged between the first pressure strip 2 and the second pressure strip 3. Through the cooperation of the positioning buckles 23 on both sides of the pressure strip and the positioning grooves on both sides of the observation groove, the pressure strip can be easily and quickly embedded in the observation groove and fixed without welding or riveting, and there are no bolts and screws on the surface that affect the overall aesthetics and flatness. The positioning buckles 23 and the positioning grooves are clamped and fixedly connected, and the cooperation of the first pressure strip 2 and the second pressure strip 3 can make the transparent window 4 firmly fixed therein, and it will not be easily displaced or fallen off.

[0033] like Figure 1-4 As shown, the first pressure strip 2 and the second pressure strip 3 both include a top piece 21 and a bottom piece 22, a first through slot is provided at the top middle position of the top piece 21, an inclined surface is provided at the upper periphery of the first through slot, the top periphery of the inclined surface is smaller than the bottom periphery, a second through slot is provided at the middle position of the bottom piece 22, the size of the second through slot is the same as the bottom of the inclined surface, the bottom of the inclined surface is fixedly connected to the top of the bottom piece 22, positioning buckles 23 are provided on the left and right sides of the bottom of the top piece 21, the top of the positioning buckle 23 is fixedly connected to the bottom of the top piece 21, a third through slot is provided on the positioning buckle 23, and the outer side of the positioning buckle 23 is fixedly connected with a buckle having the same shape as the third through slot A connecting ear 24, the top of which is open, a transparent window 4 is provided at the bottom of the bottom piece 22, and snap-in pieces 6 are provided between the transparent window 4 and the multiple side walls of the observation slot. The transparent window 4 is bonded and fixed to the door body 1, and the top piece 21 and the bottom piece 22 of the molding are connected by an inclined surface. The connecting ear 24 on the positioning buckle 23 is mainly snap-fitted and fixed with the limiting buckle 5 in the positioning slot.
