Description

Technical Field

[0001] This utility model relates to the field of exhibition display handheld signs, and in particular to a retractable luminous exhibition display handheld sign. Background Technology

[0002] Exhibitions and conventions are a collective activity that includes meetings, exhibitions, and large-scale events. The concept refers to a mass social activity in which many people gather in a certain geographical space to transmit and exchange information regularly or irregularly, formally or informally. In exhibitions and conventions, we often use display signs to showcase specific products.

[0003] The applicant discovered through a search that a Chinese patent, "A Retractable Display Handheld Sign for Exhibitions," with publication (announcement) number "CN205645092U," mainly uses a telescopic rod instead of a traditional support rod, allowing exhibition staff to shorten or extend the telescopic rod as needed for convenient use. However, this patent only relies on the first and second clamps to fix the display material, which has a limited range. Furthermore, it can only fix the bottom of the material, resulting in poor stability. Therefore, we propose a retractable luminous display handheld sign for exhibitions. Utility Model Content

[0004] The purpose of this utility model is to provide a retractable luminous handheld sign for exhibitions, in order to solve the problems mentioned in the background art, which are limited in scope and can only fix the bottom of the material, resulting in poor stability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a retractable luminous handheld sign for exhibitions, comprising a support mechanism and a retractable display mechanism. The retractable display mechanism includes four sets of fixing components. Each of the four sets of fixing components has a rechargeable multi-color light fixedly installed on its front side. Each of the four sets of fixing components is connected to a fastening bolt via a threaded sleeve. Each of the four sets of fixing components is connected to a limit spring and a clamping plate via a limit plate. Two of the sets of fixing components are connected to a first telescopic rod and a plug-in rod via mounting grooves. The other two sets of fixing components are connected to a second telescopic rod and a plug-in groove via mounting grooves.

[0006] As a preferred embodiment, the threaded sleeve is fixedly installed on the back of the fastener near both sides, and the fastening bolt is threaded inside the threaded sleeve.

[0007] As a preferred embodiment, the limiting plate is fixedly installed on the inner side of the fixing member near the front and back sides, one end of the limiting spring is fixedly installed on the limiting plate, and the clamping plate is fixedly installed on the other end of the limiting spring.

[0008] As a preferred embodiment, mounting grooves are provided on both sides of the four sets of fixing members. The first telescopic rod is slidably connected inside the mounting grooves of two sets of fixing members. The plug rod is fixedly installed on the outside of the first telescopic rod. The second telescopic rod is slidably connected inside the mounting grooves of the other two sets of fixing members. The plug groove is opened on the side of the second telescopic rod. The size of the plug rod is adapted to the plug groove.

[0009] As a preferred embodiment, the support mechanism includes a mounting frame, on the outer wall of which four sets of limiting rods are fixedly mounted. The outer ends of the four sets of limiting rods have through holes, the size of which is adapted to the threaded sleeve.

[0010] As a preferred embodiment, two sets of rotating parts are fixedly installed on the back of the mounting frame, and a support rod is rotatably connected to the outer wall of each set of rotating parts. An auxiliary frame is fixedly installed at the lower end of the support rod.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. Through the telescopic display mechanism, four sets of fixing parts can form four borders on the top, bottom, left, and right. The first and second telescopic rods can extend and retract freely within their corresponding fixing parts, adapting to the size and specifications of various display materials. The fastening bolts firmly limit the first and second telescopic rods. The four sets of fixing parts are connected tightly by the insertion rods that are precisely inserted into the insertion slots. This not only makes installation convenient but also facilitates subsequent storage and organization. The clamping plate, through moderate compression of the limiting spring, creates a space that matches the display materials and fixes them in place. In addition, the rechargeable multi-color lights make the display materials stand out clearly, improving their visibility.

[0013] 2. Through the set support mechanism, with the unique design of the opening on the limit rod precisely fitting into the outer wall of the threaded sleeve, the support mechanism and the telescopic display mechanism are seamlessly connected, forming a stable and flexible overall structure. The two sets of support rods can rotate freely along the rotating parts, making it easy for staff to lift the display materials with both hands, making the operation more convenient and efficient during the display process. When faced with a work scenario where the display materials are lifted for a long time, the staff only needs to place the auxiliary frame firmly on their shoulders to effectively distribute the weight borne by their hands, thereby significantly reducing the labor intensity of the staff and allowing the display work to be carried out more continuously and easily.
