Detailed Description

The utility model is described in further detail below with reference to the drawings and examples. The described embodiments are only some, but not all, embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 and 2, the present solution provides an L-shaped quick-mounting connection piece for a picture frame curtain frame, which includes a rectangular connection seat 1, and fishbone-shaped plugging members 2 are respectively disposed along any two adjacent sides of the rectangular connection seat 1, and the fishbone-shaped plugging members 2 can plug in frame strips 10 whose end portions are provided with cavity grooves 11 corresponding to the shape of the frame strips; after the 2 fishbone-shaped inserting parts 2 are respectively inserted into the cavity grooves 11 on the 2 frame strips 10, the 2 frame strips 10 can be vertically connected.

Specifically, as shown in fig. 2, 4 and 5, the L-shaped quick connector provided in this embodiment is only used for 90 ° connection at a corner of a curtain frame, where the rectangular connecting seat 1 is used as a corner of the curtain frame after assembly, and after 2 adjacent fishbone-shaped plugging components 2 are connected with 2 frame strips 10 with corresponding cavity grooves 11, the 2 frame strips 10 are directly plugged without punching the frame strips 10 and screwing screws.

It should be noted that, the L-shaped quick-mounting connecting piece provided in this embodiment may be integrally injection molded, and made of plastic materials; the overall shape (mainly length, width and height) of the fishbone-shaped plug-in component 2 corresponds to the cavity 11 of the frame strip 10, and the frame strip 10 can be made of aluminum alloy.

When the fishbone-shaped plugging member 2 plugs the cavity 11, since the external dimensions thereof are almost the same (in this embodiment, the height and width of the fishbone-shaped plugging member 2 are smaller than or equal to the height and width of the corresponding side of the rectangular connecting seat 1), even if the upper and lower sides of the fishbone-shaped plugging member 2 are limited by the inner wall of the cavity 11 during the plugging process, the fishbone-shaped plugging member is easily subjected to fine deformation under pressure without affecting the plugging; after the insertion is completed, if the fishbone-shaped insertion part 2 is to be pulled out of the cavity groove 11, the resistance between the upper side and the lower side of the fishbone-shaped insertion part 2 and the inner wall of the cavity groove 11 is larger than that of the insertion in the pulling-out moving process, so that the fishbone-shaped insertion part 2 can be effectively prevented from being naturally separated in the using process after the insertion of the fishbone-shaped insertion part 2 in the cavity groove 11, and the firmness of the connection of the frame strip 10 is increased.

As shown in fig. 2, in this embodiment, the fishbone-shaped plugging member 2 includes a skeleton 4 vertically connected to a side of the rectangular connecting seat 1, and mutually symmetrical bone spurs 5 are disposed along upper and lower sides of the skeleton 4, the bone spurs 5 are connected with the skeleton 4 by forming an included angle, and the bone spurs 5 face the rectangular connecting seat 1.

The framework 4 comprises a framework connecting end 6, a strip-shaped framework body 7 and a framework end 8, wherein the framework connecting end 6 is connected with the side edge of the rectangular connecting seat 1, and the upper side and the lower side of the strip-shaped framework body 7 are provided with bone spurs 5 which are symmetrical to each other.

Specifically, the bone spur 5 mainly acts on the inner wall of the cavity groove 11, and because it is connected with the skeleton 4 by an included angle, when the size of the cavity groove 11 is slightly smaller, the included angle between the bone spur 5 and the skeleton 4 in the plugging process can be further reduced, and meanwhile, under the action of the restoring force of the bone spur 5, the bone spur can tightly prop against the inner wall of the cavity groove 11, so that the firmness of the connection of the frame strip 10 is realized.

In this embodiment, the included angle between the spur 5 and the strip-shaped skeleton body 7 is 45 ° to 70 °, and the height of the cavity groove 11 on the frame strip 10 is adjusted.

As an optimization of the fishbone-shaped insertion part 2 in this embodiment, the outer end surfaces of the bone spurs 5 on the same side of the strip-shaped skeleton body 7 are horizontal, the bone spurs are identical, and the intervals between the adjacent bone spurs 5 are also identical.

The height of the bone spur 5 is greater than or equal to the height of the strip-shaped skeleton body 7.

In order to facilitate the smooth insertion of the fishbone shaped insertion part 2 into the cavity 11, the end 8 of the frame is provided with a guiding bevel 9, so that the fishbone shaped insertion part 2 is inserted into the cavity 11.

Specifically, the angle of the guiding bevel 9 is 30 ° to 70 °.

In order to facilitate the curtain frame after the assembly, can support the outer frame, this embodiment is still in the upper and lower surface of rectangle connecting seat 1 is adjacent the position of fishbone shape grafting part 2 is provided with rivet hole 3 respectively, rivet hole 3 can supply the frame to press the joint through the pin.

This structure has effectively avoided the later stage frame to adopt traditional punching and screw to connect soon loaded down with trivial details.

On the other hand, as shown in fig. 3, in this embodiment, the clearance communicated with the rivet hole 3 is further formed on the other 2 sides of the rectangular connecting seat 1, which are not connected with the fishbone-shaped plug-in component 2, so that the manufacturing difficulty of the L-shaped quick-assembly connector in this embodiment can be effectively simplified, and unnecessary friction damage in the use process of the die can be avoided.

The above description is for the purpose of illustrating the embodiments of the present utility model and is not to be construed as limiting the utility model, but is intended to cover all modifications, equivalents, improvements and alternatives falling within the spirit and principle of the utility model.
