Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0020] The terms "first," "second," and so on, in the specification and claims of this utility model and the accompanying drawings are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "including," "having," and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, apparatus, product, or end comprising a series of steps or elements is not limited to the listed steps or elements but may optionally include steps or elements not listed therein, or may optionally include other steps or elements inherent to such process, method, product, or end.

[0021] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] This utility model discloses a specific embodiment of a connector for an LED display box. Figures 1 to 3 The connecting parts include a base 1, a telescopic rod 2, an eccentric wheel 3, a locking rod 5, a locking block 4, a spring and a locking seat 6.

[0023] In this embodiment, a sliding groove 11 is formed at the end of the base 1, into which the end of the telescopic rod 2 is inserted. A long hole 21 is formed in the middle of the telescopic rod 2. It should be noted that the telescopic rod 2 can slide along the sliding groove 11. In order to keep the telescopic rod 2 stationary or locked relative to the base 1, a locking mechanism is provided between the base 1 and the telescopic rod 2.

[0024] In this embodiment, the locking mechanism comprises an eccentric wheel 3, a locking block 4, a locking seat 6, and a locking rod 5. The locking seat 6 is fixedly mounted on the top surface of the base 1. A through-hole is provided in the middle portion of the locking seat 6, which is aligned in height with the elongated hole 21 of the telescopic rod 2. A groove 61 is provided on the top surface of the locking seat 6, which is in close contact with the outer peripheral side of the eccentric wheel 3. The groove 61 serves to limit the position of the eccentric wheel 3. It should be noted that the eccentric wheel 3 is located on the top surface of the base 1 (locking seat 6), and the eccentric wheel 3 can be provided with two arc surfaces of different radii. The eccentric wheel 3 is rotatably mounted on the top end of the locking rod 5 via a rotating shaft. The bottom end of the locking rod 5 is inserted from the top surface of the base 1 (the through-hole of the locking seat 6) and then passes through the elongated hole 21 of the telescopic rod 2.

[0025] In this embodiment, the locking block 4 is fixedly mounted on the bottom end of the telescopic rod 2. Specifically, the bottom surface of the base 1 defines a through-hole for inserting the locking block 4. The top surface of the locking block 4 is formed with a first latching portion, and the bottom surface of the telescopic rod 2 is formed with a second latching portion that engages with the first latching portion. Preferably, the first latching portion is a latching protrusion 41, and the second latching portion is a plurality of latching slots 23 spaced apart along the length of the telescopic rod 2. In addition to the latching protrusion 41 and the latching slot 23, other latching structures are also possible.

[0026] In addition, in order to facilitate the return of the locking block 4, a spring is provided on the outer peripheral side of the locking rod 5 to drive the locking block 4 to move downward. It can be understood that a spring is provided between the lock seat 6 and the locking block 4 to drive the locking block 4 to move downward.

[0027] The specific working process is as follows: when the eccentric wheel 3 is rotated to the released state, the spring drives the locking block 4 downward, so that the locking protrusion 41 of the locking block 4 disengages the locking groove 23 of the telescopic rod 2. When locking is required, the eccentric wheel 3 is turned, and the eccentric wheel 3 drives the locking rod 5 upward. Since the locking rod 5 is fixedly connected to the locking block 4, the upward movement of the locking rod 5 drives the locking block 4 upward and compresses the spring, so that the locking protrusion 41 of the locking block 4 is inserted into the locking groove 23 at the bottom of the telescopic rod 2, thereby limiting the sliding adjustment of the telescopic rod 2 and completing the locking fixation between the telescopic rod 2 and the base 1, so that the length of the connecting piece can be adjusted.

[0028] To further enhance operational convenience, the eccentric wheel 3 extends outwardly with a toggle portion 31. Furthermore, the left and right sides of the telescopic rod 2 are each provided with a plurality of grooves 22 spaced apart along the length of the telescopic rod 2. Corresponding balls or spherical bodies can be provided on the inner sidewall of the base 1 to create damping and enhance the feel of the adjustment operation.

[0029] It should be noted that the outward end of the telescopic rod 2 and the outward end of the base 1 are respectively hinged with a hinge seat 13, and the hinge seat 13 is mainly used to connect to an external LED box.

[0030] In this embodiment, the top surface of the telescopic rod 2 is provided with a scale mark, and the top surface of the base 1 is provided with a window 12 aligned with the scale mark in the height direction. The operator can visually observe the current extension and contraction of the connector through the window 12, further improving the convenience of adjustment operation. Compared with the prior art, the connector of this embodiment is simple to operate and has a simple and compact structure, which solves the problem of inconvenience in previous use.

[0031] Finally, it should be noted that the connector for an LED display box disclosed in the embodiment of the present invention is only a preferred embodiment of the present invention, and is only used to illustrate the technical solution of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features therein can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
