Description

Technical Field

[0001] The utility model belongs to the technical field of picture frame installation, and more specifically relates to a picture frame installation device. Background Art

[0002] Picture frames are decorative items used to place and display paintings, photographs, embroidery and other works of art. They are mainly used to select, position, support and decorate the four sides of the portrait. In addition, picture frames are also beneficial to protecting the quality of the portrait. In order to facilitate hanging, existing picture frames are generally equipped with hanging rings on the back of the picture frame. The hanging rings cooperate with the screws on the wall to achieve stable hanging of the picture frame. However, this hanging structure of hanging rings and screws has the following defects. First, due to the presence of the hanging rings, the surface of the picture frame is not flat enough, which is not conducive to stacking and transporting multiple picture frames. Second, in order to ensure the stability of the hanging, multiple sets of hanging rings and screws are generally used to cooperate with each other, so that the screw embedding position must be consistent with the hanging ring, and there are certain precision requirements for the installation position of the screw.

[0003] After searching, the patent CN216060037U discloses a simple picture frame hanging structure. The application includes a closed-loop frame, and the accommodation space formed by the closed-loop frame is used to place the portrait. The closed-loop frame extends inward with a panel, and the side edge of the panel is provided with a toothed structure, and the panel is provided with a hanging hole. When the picture frame is in a hanging state, it is hung on a screw column on the surface to be installed through the hanging hole and the toothed structure is mounted on another screw column on the surface to be installed, so that the picture frame is hung on the surface to be installed. In this way, the picture frame can be hung on the surface to be installed through the hanging hole, and the toothed structure cooperates with the screw teeth of the screw column to play a stabilizing role, so as to avoid the picture frame from shaking left and right due to the unstable hanging. Although the application eliminates the use of the hanging ring, so that the surface of the picture frame can be flat, which does not affect the stacking and transportation of the picture frame; however, the assembly between the hanging hole and the screw column still requires high precision for the installation position of the screw column.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] The present invention will be further described below in conjunction with specific embodiments.

[0040] refer to Figure 2 、 Figure 3 As shown, a picture frame mounting device according to this embodiment includes a suspension mechanism 1 consisting of a suspension bracket 11 and a connecting assembly 12. The suspension bracket 11 is generally T-shaped and includes a cross arm 111 and a counterweight arm 112 extending vertically from the lower surface of the cross arm 111. Furthermore, a support surface 1111 is formed on the upper surface of the cross arm 111 for suspending the picture frame 3.

[0041] The connecting assembly 12 is rotatably mounted in the mounting hole 1112 on the cross arm 111 and is used to be fixed to the surface to be mounted. The cross arm 111 is balanced with the connecting assembly 12 as a fulcrum under the action of the counterweight arm 112.

[0042] This embodiment of a picture frame mounting device is used by first securing the entire device to the wall to be mounted using the connecting assembly 12. At this point, the cross arm 111 is in a balanced state. Next, the upper edge of the picture frame 3 is hung on the support surface 1111 of the cross arm 111, and the picture frame 3 is moved left and right to maintain the cross arm 111 in balance. Compared to the traditional structure of a hanging ring and screws, this embodiment of the picture frame mounting device not only ensures a flat surface for the picture frames, thus ensuring they can be stacked and transported, but also eliminates the need to consider the positioning requirements between the hanging ring and the screws, significantly simplifying installation.

[0043] As a specific embodiment of the connection component 12, refer to Figure 3 、 Figure 4 As shown, the connecting assembly 12 includes a bearing 121, a pin 122, and a screw cap 123. The bearing 121 is mounted in the mounting hole 1112. The pin 122 includes a stopper 1221, a connecting portion 1222, and a pointed portion 1223, respectively disposed on either side of the stopper 1221. The connecting portion 1222 is designed to engage the inner ring of the bearing 121, while the pointed portion 1223 is designed to be driven into the mounting surface. The stopper 1221 is preferably a retaining ring, used to stop and limit the bearing 121 from one side.

[0044] The screw cap 123 includes a screw cap 1231 and a connecting rod 1232. The screw cap 1231 can be positioned within the mounting hole 1112, while the connecting rod 1232 extends into the connecting hole 1224 on the connecting portion 1222, completing the connection with the pin 122. Preferably, the connecting rod 1232 can be a threaded rod, and the connecting hole 1224 can be a threaded hole.

[0045] Furthermore, universal wheels 13 are provided on the side of cross arm 111 that contacts the mounting surface. At least two universal wheels 13 are provided, one on each side of mounting hole 1112. In other words, at least one universal wheel 13 is provided on each side of mounting hole 1112. The provision of universal wheels 13 reduces friction between cross arm 111 and the mounting surface, thereby facilitating rapid balancing of cross arm 111.

[0046] Specifically, in this embodiment, two universal wheels 13 are provided, symmetrically distributed around the mounting hole 1112, and are installed in the assembly hole near the end of the cross arm 111. Furthermore, to ensure that the cross arm 111 itself can remain in a balanced state as much as possible, the counterweight arm 112 and the mounting hole 1112 are both located in the middle of the cross arm 111.

[0047] like Figure 1As shown, a picture frame installation device of this embodiment further includes a clamping mechanism 2 on the basis of the above embodiment, and the clamping mechanism 2 is used to press the upper edge of the picture frame 3 suspended on the cross arm 111 to prevent the picture frame from falling off the suspension mechanism 1.

[0048] Specifically, refer to Figure 5-Figure 7 As shown, the clamping mechanism 2 includes a movable clamping plate 21. The movable clamping plate 21 has an overall U-shaped structure, comprising an upper plate 211, a lower plate 212, and side plates 213. The lower plate 212 and side plates 213 are provided with escape grooves 214. The movable clamping plate 21 is secured to the cross arm 111 via the escape grooves 214, creating a limited space between the upper plate 211 and the support surface 1111 for the upper side frame 3 to engage. Furthermore, a limit spring 23 is installed between the lower plate 212 and the lower surface of the cross arm 111 to ensure that the upper plate 211 can consistently exert a compressive force on the upper side frame 3.

[0049] Furthermore, the clamping mechanism 2 further includes a fixed clamping plate 24, which includes a clamping sleeve 241 that is sleeved on the counterweight arm 112, and fixed plates 242 located on both sides of the clamping sleeve 241. The clamping sleeve 241 is located in the avoidance groove 214, and the fixed plates 242 are located between the upper plate 211 and the lower plate 212, and are respectively in contact with the lower surface of the corresponding cross arm 111.

[0050] A limit post 22 is connected to the lower surface of the fixed plate 242. The lower plate 212 has a through hole through which the limit post 22 slides up and down. A limit spring 23 is mounted on the limit post 22 and is trapped between the lower plate 212 and the fixed plate 242. To prevent the limit post 22 from dislodging from the through hole in the lower plate 212, a stopper can be installed at the end of the limit post 22. Furthermore, a handle 25 can be provided on the upper plate 211 to facilitate pulling the movable clamping plate 21 upward.

[0051] The picture frame installation device of this embodiment is characterized in that, during assembly, the handle 25 is pulled upward to drive the clamping plate 21 to move upward as a whole, thereby moving the upper plate 211 away from the supporting surface 1111 of the cross arm 111, so that the limiting space becomes larger; at the same time, the lower plate 212 will compress the limiting spring 23; then, the upper side frame of the picture frame 3 is inserted into the limiting space, and then the handle 25 is released; at this time, under the action of the restoring force of the limiting spring 23, the upper plate 211 moves downward, thereby pressing the upper side frame of the picture frame 3 to prevent the picture frame 3 from accidentally falling.

[0052] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the inventive purpose of the present invention, designs a structure and embodiment similar to the technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
