Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, in particular to a notch accessory and a door and window thereof. Background Art

[0002] Among the installation accessories for doors and windows, there is a base accessory installed at the notch position of the door and window frame. For the convenience of installation, the width of the positioning steps on both sides of the base accessory is set to be smaller than the width of the notch, so that the two sides of the base accessory can be respectively embedded in the notch by adjusting the position left and right, and then the top surface of the base accessory is pressed against the inner side of the notch by tightening the screws, and the base accessory is fixed by the mutual pressure between the base accessory and the inner wall of the notch, so that the base accessory and the door and window frame are relatively fixed. However, since the distance between the positioning steps on both sides of the base accessory is smaller than the distance between the inner sides of the notch, the base accessory is easy to fall out of the notch during installation due to the large movable space along the width direction of the notch, so that the connection between the base accessory and the door and window frame is not stable enough in the width direction of the notch. Utility Model Content

[0003] The utility model aims to provide a notch fitting and a door and window thereof, so as to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The technical solution adopted to solve the above technical problems is: a slot accessory, including: a base, with positioning steps on both sides of the top, and a concession notch is provided at the top of the positioning step near one side of the base; an elastic member, installed at the bottom of the base, and the elastic member can provide elastic force in the vertical direction.

[0005] The technical solution has at least the following beneficial effects: a recessed corner is provided at the top of the positioning step on one side of the base, so that the side of the base close to the recessed corner can be first embedded in the groove of the door and window frame, and through the space of the recessed corner, the side of the base away from the recessed corner can also be embedded in the groove of the door and window frame, and then by adjusting the left and right positions of the base, the positioning steps on both sides of the base can be adapted and abutted against the inner side wall of the groove under the action of the elastic member pressing against the bottom wall of the groove, so that the preliminary positioning and limitation of the base can be achieved, and the further fixed installation of the base can be assisted, thereby improving the efficiency of the installation of the base; the technical solution can not only realize the direct embedding of the base into the groove from the opening of the groove, but also ensure the positioning effect between the base and the inner wall of the groove after the base is embedded in the groove, and while facilitating the embedding and installation of the base, when the base is subjected to a force in the lateral direction, it is not only limited by the friction between the base and the inner side wall of the groove of the door and window frame, but also limited by the abutment between the positioning steps of the base and the inner side wall of the groove of the door and window frame, thereby ensuring the stable installation of the base in the lateral direction.

[0006] As a further improvement of the above technical solution, the recessed corner forms a V-shaped notch on one side of the top of the base. The recessed V-shaped notch forms a recessed space so that the side of the base close to the recessed corner is closer to the inner wall of the groove, and the side of the base away from the recessed corner can be directly embedded in the groove.

[0007] As a further improvement of the above technical solution, the notched corner forms a first inclined surface on one side of the top of the base. When the base is inserted into the groove near the notched corner, the inner wall of the groove slides relative to the first inclined surface of the base, so that the base can be directly inserted into the groove away from the notched corner.

[0008] As a further improvement of the above technical solution, the recessed corner forms an inwardly concave arc surface on one side of the top of the base. When the base is inserted into the groove near the recessed corner, the inner wall of the groove and the arc surface of the base slide relative to each other, so that the base can be directly inserted into the groove away from the recessed corner.

[0009] As a further improvement of the above technical solution, the elastic member is a spring, and a mounting groove is provided at the bottom of the base, and one end of the spring is embedded in the mounting groove. The spring can provide the base with a force that conflicts with the inner wall of the groove, thereby playing a role in preliminary positioning and limiting the base, so as to facilitate the subsequent further fixation of the base; embedding one end of the spring in the mounting groove can facilitate the installation and fixation between the spring and the base, and has a simple structure, low cost, and good economy.

[0010] As a further improvement of the above technical solution, the elastic member is an elastic sheet, one end of which is installed on the side of the base away from the positioning step, and the other end extends in a direction away from the base and then bends toward the base. The elastic sheet has good elastic stability, and when the base slides in the groove to adjust its position, the elastic sheet can contact the bottom wall of the groove more stably, and is not prone to large deformation due to friction between the bottom wall of the groove, thereby affecting the sliding of the base.

[0011] As a further improvement of the above technical solution, the base is threadedly installed with a set screw. After the base is initially positioned and installed in the groove, the set screw is rotated to press against the bottom wall of the groove, and the base is fixed at the required position of the groove by the mutual pressure between the set screw and the bottom wall of the groove and the mutual pressure between the base and the inner wall of the groove, so as to achieve fixed installation of the base, with a simple structure and convenient operation, which can improve the installation efficiency of the base.

[0012] As a further improvement of the above technical solution, a second inclined surface is provided on one or both sides of the bottom of the base, and the second inclined surface is inclined toward the top of the base. When the base is embedded in the groove in an inclined posture, the second inclined surface can better fit the inner wall of the groove, so that the base can be better embedded in the groove, or the size of the groove can be relatively smaller and more beautiful, and the gap between the base and the inner wall of the groove can be reduced, so as to better ensure the installation stability of the base.

[0013] A door and window, comprising the notch fitting and a door and window frame, wherein a groove for the base to be installed is provided in the door and window frame, the elastic member is pressed against the bottom wall of the groove at one end away from the base, the groove is provided with convex edges on both sides of the notch, the distance between the positioning steps on both sides of the base is the same as the distance between the two corresponding convex edges, the depth of the groove is greater than the thickness of the base, and the width of the groove is greater than the width of the base. Through the space given up by the notch, the two sides of the base can be directly embedded in the groove from the opening of the groove, so as to facilitate the subsequent installation of functional structural components on the door and window frame through the base, and the base can be initially positioned by the elastic member, which can facilitate the subsequent further fixing of the base.

[0014] As a further improvement of the above technical solution, the door and window frame is provided with a chamfer at the opening of the groove, so that the base can be better embedded in the groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0030] Reference Figure 1-2A slot accessory includes a base 10 and an elastic member. Positioning steps 11 are provided on both sides of the top of the base 10. A relief corner 12 is provided on the top of the positioning step 11 close to one side of the base 10. The relief corner 12 is located at the connection position between one side of the positioning step 11 and the top surface of the base 10. An elastic member is installed at the bottom of the base 10. The elastic member can provide the base 10 with elastic force in a direction perpendicular to the plane where the two positioning steps 11 are located.

[0031] A door and window comprises the above-mentioned notch fitting and a door and window frame 40, wherein the door and window frame 40 is provided with a groove 41, and a convex edge is provided at the opening position of the groove 41, so that the cross-sectional shape of the groove 41 is T-shaped, and the base 10 can be embedded in the groove 41 and slide in the groove 41 along the extension direction of the groove 41. The distance between the positioning steps 11 on both sides of the base 10 is the same as the distance between the two corresponding convex edges, so that the positioning steps 11 on both sides of the base 10 can be positioned and engaged with the inner side wall and the convex edge of the groove 41. When the base 10 is subjected to a lateral force, not only the friction between the base 10 and the inner side wall of the groove 41 of the door and window frame 40 limits the position of the base 10, but also the interference between the positioning steps 11 of the base 10 and the inner side wall of the groove 41 of the door and window frame 40 limits the position of the base 10, thereby ensuring the stable installation of the base 10 in the lateral direction and ensuring the accuracy and stability of the installation position of the base 10. One end of the elastic member presses against the bottom of the base 10 , and the other end presses against the bottom wall of the groove 41 , so that the positioning step 11 of the base 10 abuts against the inner wall of the groove 41 , achieving a preliminary positioning and fixing effect.

[0032] The depth of the groove 41 is greater than the thickness of the base 10, so that when one side of the base 10 is tilted and inserted into the groove 41, there is no interference between the base 10 and the bottom wall of the groove 41. The inner width of the groove 41 is greater than the width of the base 10, so that when one side of the base 10 is tilted and inserted into the groove 41, there is no interference between the base 10 and the inner wall of the groove 41, ensuring that the base 10 can be smoothly inserted into the groove 41.

[0033] A second inclined surface 16 is provided on one or both sides of the bottom of the base 10. The second inclined surface 16 is inclined toward the top of the base 10, so that the sides of the base 10 are thinner as they are closer to the ends. When the base 10 is inserted into the groove 41 in an inclined state, the second inclined surface 16 is equivalent to reducing the interference between the two sides of the bottom of the base 10 and the bottom wall of the groove 41, so that the base 10 can be better inserted into the groove 41. The second inclined surface 16 can better fit the inner wall of the groove 41, making the size of the groove 41 relatively smaller and more beautiful, and can also reduce the gap between the base 10 and the inner wall of the groove 41, so as to better ensure the installation stability of the base 10. In order to make it easier for the base 10 to be inserted into the groove 41, inclined chamfers 42 or arc chamfers 42 can be provided on both sides of the door and window frame 40 at the opening of the groove 41.

[0034] Reference Figure 3 When the base 10 is installed in the door and window frame 40, the side of the base 10 close to the notch 12 is first tilted toward the groove 41 so that the side of the base 10 close to the notch 12 can be embedded in the groove 41; Figure 3 b, due to the provision of the notch 12, the base 10 can be moved toward the side where the notch 12 is located, so that the side of the base 10 away from the notch 12 can be smoothly embedded in the groove 41, at this time, the base 10 can be completely embedded in the groove 41; refer to Figure 3 In c, by adjusting the position of both sides of the base 10, the positioning steps 11 on both sides of the base 10 can be adapted and interfered with the inner side walls of the groove 41 to determine the precise installation position of both sides of the base 10. At the same time, under the elastic force of the elastic member, the mutual interference between the positioning steps on both sides of the base 10 and the inner side walls of the groove 41 can be maintained, and the positions of both sides of the base 10 are preliminarily positioned and fixed, so as to facilitate the subsequent movement of the base 10 along the extension direction of the groove 41 to adjust the position of the base 10. At the same time, it can also facilitate the subsequent fixed installation of the base 10 and improve the efficiency of the installation of the base 10.

[0035] When it is necessary to conveniently install the functional component on the door and window, the structure of the functional component can be set on the top of the base 10, and then the base 10 can be installed in the groove 41 of the door and window frame 40. For example, when the rotating shaft seat of the door and window needs to be installed, the rotating shaft cylinder for installing the rotating shaft can be set on the top surface of the base 10, so that the rotating shaft seat is installed in the groove 41 of the door and window frame 40 as a whole, and then through subsequent fixing, the convenient installation of the rotating shaft seat can be realized.

[0036] A set screw 30 is spirally installed through the base 10. Two set screws 30 are provided. The two set screws 30 are screwed into the base 10 and abut against the bottom wall of the groove 41. Under the positioning restriction effect of the positioning steps 11 on both sides of the base 10 and the inner wall of the groove 41, the end of the set screw 30 abuts against the groove 41, thereby fixing the position of the base 10, which can facilitate the installation and disassembly of the base 10.

[0037] In this embodiment, the elastic member is a spiral spring 21, and a mounting groove 22 is provided in the middle of the bottom of the base 10. The mounting groove 22 is located between two set screws 30. One end of the spring 21 is embedded and clamped in the inner wall of the mounting groove 22, and the other end extends out of the mounting groove 22 and protrudes out of the bottom of the base 10. When the base 10 is embedded in the groove 41, one end of the spring 21 abuts against the bottom wall of the groove 41, and the other end abuts against the bottom of the base 10, supporting the base 10, so that the positioning steps 11 on both sides of the top of the base 10 can be positioned and abutted against the inner side wall of the groove 41, thereby realizing the preliminary positioning of the base 10.

[0038] Reference Figure 4 In other embodiments, the elastic member may also be an elastic sheet 23, one end of which is fixed at the middle position of the bottom of the base 10, and the other end is extended a distance away from the base 10, and then bent toward the base 10, so that the end of the elastic sheet 23 away from the base 10 forms an arc surface and contacts the bottom wall of the groove 41, which has an upward push effect on the base 10. The elastic sheet 23 is arranged horizontally at the bottom of the base 10 and between the two set screws 30. In order to provide a more stable elastic force, two elastic sheets 23 may be provided, and the two elastic sheets 23 are centrally symmetrically distributed at the bottom of the base 10.

[0039] Reference Figure 5 In this embodiment, the setting of the notch 12 allows one side of the top of the base 10 to form an inwardly recessed V-shaped groove 13, the cross-section of the V-shaped groove 13 is V-shaped, and the opening angle of the V-shaped groove 13 is between ninety degrees and one hundred and twenty degrees. The space vacated by the V-shaped groove 13 allows the two sides of the base 10 to be successively embedded in the groove 41, so as to realize the convenient installation of the base 10.

[0040] Reference Figure 5In other embodiments, the setting of the notch 12 allows a first inclined surface 14 to be formed on one side of the top of the base 10. When the base 10 is inserted into the groove 41 near the notch 12, the inner wall of the groove 41 and the surface of the first inclined surface 14 of the base 10 slide relative to each other, so that the base 10 away from the notch 12 can be directly inserted into the groove 41. The inclination angle of the first inclined surface 14 is between 45 and 65, so that the space left by the first inclined surface 14 can be guaranteed, and the two sides of the base 10 can be inserted into the groove 41 one after another, so as to realize the convenient installation of the base 10.

[0041] Reference Figure 5 In other embodiments, the setting of the notch 12 allows a side of the top of the base 10 to form an inwardly concave arc surface 15. When the base 10 is inserted into the groove 41 near the notch 12, the inner wall of the groove 41 and the surface of the arc surface 15 of the base 10 slide relative to each other, so that the side of the base 10 away from the notch 12 can be directly inserted into the groove 41, so as to realize the convenient installation of the base 10.

[0042] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
