Technical Field

[0001] This utility model belongs to the field of illuminated sign technology, and more specifically, it relates to a connection structure for illuminated signs. Background Technology

[0002] Illuminated letters are short for LED illuminated letters, also known as illuminated signboards, illuminated advertising letters, etc. They are iconic advertising products from a specific period in the development of the advertising signage industry; today they are widely used in diverse scenarios such as streets and alleys, high-rise buildings, roads, bridges, and towers, and are an indispensable functional advertising sign for people's daily lives and work.

[0003] In existing illuminated signs, the lampshade and the sign housing are usually fixed together by multiple sets of fastening screws. When it is necessary to inspect the LED light-emitting modules inside the sign housing, multiple sets of fastening screws must be removed before the lampshade can be taken off, which is cumbersome, time-consuming, and labor-intensive. Therefore, in view of this, this paper studies and improves the existing structure and its shortcomings, and provides a connection structure for illuminated signs to achieve a more practical purpose.

[0027] Example:

[0028] As attached Figure 1 To be continued Figure 6 As shown:

[0029] This utility model provides a connection structure for illuminated characters, including a main housing 1. A connecting frame 2 is installed on one side of the main housing 1. A lampshade 3 is fixedly installed on the inner side of the connecting frame 2. A fixing plate 4 is fixedly installed on the inner side of the main housing 1 corresponding to the lampshade 3. An LED module is fixedly installed on the fixing plate 4 on the side close to the lampshade 3. Four sets of mounting slots are symmetrically provided on the fixing plate 4. A moving block 5 is slidably connected to the inner side of each mounting slot. A top block 6 is fixedly installed on one side of each moving block 5. One side of each top block 6 abuts against the inner side of the connecting frame 2.

[0030] The main housing 1 is equipped with a cross drive frame 7 on its inner side. The cross drive frame 7 is located on the side of the fixing plate 4 away from the lamp cover 3. Each of the four ends of the cross drive frame 7 is provided with a first inclined surface. One end of each of the moving blocks 5 passes through the mounting groove and is provided with a second inclined surface. The four sets of first inclined surfaces are slidably connected to the four sets of second inclined surfaces, which can drive the four sets of moving blocks 5 to move flexibly at the same time.

[0031] The inclined surface one is provided with a sliding groove, and the inclined surface two is fixedly installed with a slider 8 that is slidably connected to the sliding groove. When the cross drive frame 7 moves away from the lampshade 3, it can drive the top block 6 away from the connecting frame 2, so as to prevent the top block 6 from obstructing the movement of the connecting frame 2.

[0032] The fixing plate 4 has a screw 9 rotatably connected to it via a bearing on the side away from the lamp cover 3. The outer side of the screw 9 is threadedly connected to the inner side of the middle part of the cross drive frame 7, which can drive the cross drive frame 7 to move flexibly. At the same time, by utilizing the self-locking characteristic of the threaded engagement (the thread helix angle is less than the equivalent friction angle of the thread contact surface, and under axial load, the friction force generated between the screw and the nut is sufficient to prevent relative rotation of the threaded pair), self-locking can be achieved after movement.

[0033] The main housing 1 has a rear cover plate 13 fixedly installed on one side by fasteners. The rear cover plate 13 has a through hole that is rotatably connected to the screw 9. The screw 9 has an internal hexagonal hole at one end located in the through hole, which can be used to drive the screw 9 to rotate flexibly by an external hexagonal tool.

[0034] The main housing 1 has a connecting seat 11 on one side, and the connecting frame 2 has a connecting groove 12 that is slidably connected to the connecting seat 11. A sealing ring is fixedly bonded to the inner side of the connecting groove 12 to prevent external water from entering the main housing 1 through the junction of the main housing 1 and the connecting frame 2.

[0035] Each of the movable blocks 5 is fixedly installed with a slide rod 10 on one side, and each of the inner walls of the mounting groove is provided with a limiting groove that can slide and connect with the slide rod 10 to prevent the movable blocks 5 from falling off the mounting groove.

[0036] The top block 6 is made of rubber, and the top block 6 has anti-slip texture on the side that abuts against the connecting frame 2 to increase the stability of the connecting frame 2 when it is fixed.

[0037] The working principle of this embodiment is as follows: When it is necessary to install illuminated signs, firstly, connect the connecting slot 12 to the connecting seat 11 and connect the connecting frame 2 to the main housing 1. Then, use an external hexagonal tool to rotate the screw 9 to drive the cross drive frame 7 to move. The cross drive frame 7 drives the moving block 5 to move. The moving block 5 drives the top block 6 to move and press against the inner side of the connecting frame 2. The connecting frame 2 is fixed by the static friction between the top block 6 and the connecting frame 2. When it is necessary to remove the connecting frame 2 and the lampshade 3, rotate the screw 9 to drive the cross drive frame 7 to move in the opposite direction. The cross drive frame 7 drives the top block 6 to leave the connecting frame 2. Remove the connecting frame 2 and the lampshade 3 to complete the installation and removal of the connecting frame 2 and the lampshade 3 from the main housing 1.

[0038] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
