Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
It should be noted that the features of the embodiments of the present invention may be combined with each other without conflict.
The section bar is an object with a certain section shape and size, which is made of iron or steel and materials with certain strength and toughness through plastic processing (such as rolling, extrusion, casting and other processes). The section bar has various varieties and specifications and wide application, and plays a very important role in rolling production. The section bar can be used independently and can be further processed into other manufactured products.
The section bar has the advantages of flexible assembly, rapid installation, convenient transportation, beautiful appearance, practicality and the like. At present, profiles are often used in the production of building structures or frame-like products. People can select parameters such as specific shape, material, heat treatment state, mechanical property and the like of the section bar according to design requirements, and then the section bar is subjected to operations such as segmentation, splicing and the like according to specific size and shape requirements, and finally the required structural product is obtained.
At present, when frame structures (such as mirror frames, mirror cabinets, doors and windows, bathroom doors, bathroom furniture door frames, door cabinets and the like) are produced and manufactured by using sectional materials, a 45-degree splicing mode is mostly adopted by means of corner connectors, and the existing splicing method is as follows:
firstly, two sectional materials forming an angle with each other are fixedly connected with an angle connector by adopting fasteners such as screws and the like;
and secondly, adopting glue to bond and fix two sections forming an angle with the angle connector.
However, in the first method, the corner brace and the corresponding position of the section bar need to be subjected to finish machining for many times (such as drilling, forming threaded holes and the like); due to the structural characteristics of the section of the sectional material, the difficulty of screw assembly is high; resulting in low assembly efficiency and difficulty in achieving desired assembly effects, thereby affecting the aesthetic appearance of the product.
Aiming at the second method, glue is adopted for fixing, and compared with a screw fixing mode, the method is simple to operate. However, the method has a large demand for glue, and the assembly can be smoothly carried out only by means of a special tool during assembly; in addition, the curing time of the glue after the assembly is finished is long, and the curing time is inconsistent, so that the production efficiency is low.
In view of the above problems, referring to fig. 1 and fig. 2, an embodiment of the invention provides a frame splicing structure 100, which can be applied to, but is not limited to: products such as picture frame, mirror cabinet, door and window, bathroom door, bathroom furniture door frame, door cabinet, this application does not use this as the limit, and the user is decided according to the in-service use demand.
The frame splicing structure 100 includes a first section bar 110, a second section bar 120 and a splicing element 130.
Wherein, the splicing element 130 is provided with a first elastic buckle 1313 and a second elastic buckle 1333. In the assembling process, according to the principle that the first elastic buckle 1313 and the second elastic buckle 1333 are elastically deformed under the action of external force and recover to the initial state after the external force disappears, the splicing element 130 is clamped and fixed with the first profile 110 through the first elastic buckle 1313 and is clamped and fixed with the second profile 120 through the second elastic buckle 1333.

When the first profile 110 and the second profile 120 are spliced by the splicing member 130, the first elastic buckle 1313 and the second elastic buckle 1333 are both located on the inner side of the frame, and the outer side is not visible, which is beneficial to improving the aesthetic property of the frame.
Referring to fig. 9, in particular, the first elastic buckle 1313 includes a first elastic body 13131 and a first bump 13133.
The first elastic body 13131 is connected to the first insertion portion 13111 and extends toward the first matching portion 13115, and the first protrusion 13133 is protruded from a side of the first elastic body 13131 away from the first clamping portion 13113.
The first elastic body 13131 has a tendency to be elastically deformed when an external force is applied thereto. When the first connecting body 131 is engaged with the first section bar 110, the first protrusion 13133 of the first elastic buckle 1313 is pressed by the peripheral wall of the first inner cavity 111, so that the first elastic body 13131 is driven to deflect toward one side of the first engaging portion 13113, that is, the first elastic buckle 1313 is elastically deformed. When the first protrusion 13133 moves to match with the first engaging hole 112 of the first profile 110 under the action of external force, the first protrusion 13133 is engaged with the first engaging hole 112, the extrusion force disappears, and the first elastic body 13131 recovers to the original state, thereby completing the engaging assembly of the first connecting body 131 and the first profile 110.
Similarly, the second elastic buckle 1333 includes a second elastic body 13331 and a second protrusion 13333 protruding from the second elastic body 13331. The second elastic body 13331 has a tendency of elastic deformation under the action of external force, and when the second connector 133 and the second profile 120 are in snap fit, the second protrusion 13333 is pressed by the peripheral wall of the second cavity 121 to drive the second elastic body 13331 to deflect, i.e. the second elastic buckle 1333 is elastically deformed. When the second protrusion 13333 moves to be matched with the second clamping hole 123 of the second profile 120 under the action of external force, the second protrusion 13333 is clamped at the position of the second clamping hole 123, the extrusion acting force disappears, and the second elastic body 13331 recovers to the initial state, thereby completing the clamping assembly of the second connector 133 and the second profile 120.
In order to realize the purposes of convenient clamping and difficult disengagement after clamping. Optionally, the first bump 13133 is located at an end of the first elastic body 13131 away from the first embedding portion 13111, which is beneficial to saving labor during the clamping process. In addition, the first tab 13133 includes a first guiding inclined surface 13135, and an included angle between the first guiding inclined surface 13135 and the first direction 101 is an obtuse angle. In the assembling process, under the action of external force, the peripheral wall of the first inner cavity 111 of the first section bar 110 relatively moves along the first guide inclined surface 13135, so that the first elastic buckle 1313 and the first section bar 110 are conveniently clamped, and the reverse buckle structure is formed after clamping and is not easy to separate. Similarly, the second protrusion 13333 includes a second guiding inclined surface 13335, and an included angle between the second guiding inclined surface 13335 and the second direction 103 is an obtuse angle, so that the second elastic buckle 1333 and the second profile 120 are conveniently clamped, and an effect that the inverted buckle structure is not easy to be disengaged is formed after clamping.
