Description

Technical Field

[0001] This utility model relates to the field of mobile phone storage rack technology, specifically a mobile phone storage rack for teaching and examination supervision. Background Technology

[0002] During the examination, invigilators must ensure the fairness and impartiality of the examination and prevent candidates or invigilators from using mobile phones for cheating, such as checking answers, transmitting information, or communicating. Using mobile phone storage racks can facilitate the unified management of mobile phones by invigilators, avoiding problems such as misplaced phones, loss, or damage. At the same time, after the examination, invigilators can quickly return the phones to the corresponding candidates, improving work efficiency.

[0003] The currently published CN216291040U discloses a mobile phone storage rack for high school invigilators, relating to the field of mobile phone storage rack technology. It includes a bracket, with a storage rack fixedly installed at the upper end of the bracket. A hook and a wall sticker are fixedly installed on the right surface of the storage rack. A storage bag is located on the right side of the storage rack, and a spring is fixedly installed inside the storage bag. A base is fixedly connected to the upper end of the spring, a connecting strip is fixedly connected to one end of the base, and a fixing plate is fixedly connected to one end of the connecting strip. By configuring the storage bag, spring, base, connecting strip, fixing plate, slider a, groove a, and flexible plate, when a mobile phone is placed in the storage bag, the weight of the mobile phone presses down on the spring under the base. At this time, the connecting strip drives the fixing plate to press the mobile phone inward until the flexible plate adheres to both sides of the mobile phone, thus fixing the mobile phone and preventing it from shaking inside the storage bag when being taken out or put in, facilitating practical use.

[0004] However, the above technology still has the following problems:

[0005] Using a phone holder during exams is inconvenient because it's difficult to move or transport the phone. Also, if the holder tipes over, the phone could easily fall and damage it, causing unnecessary losses. Furthermore, the gap between the two storage bags in the top and bottom directions means that the holder is quite tall after use and takes up a lot of space. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a mobile phone storage rack for teaching and examination supervision. It is equipped with a bracket, pulleys, and a pull rod, and a cotton pad is placed inside the storage bag to facilitate the movement of the mobile phone storage rack and prevent the risk of the mobile phone being damaged by drops. At the same time, it can appropriately reduce the space occupied.

[0007] This utility model provides the following technical solution: a mobile phone storage rack for teaching and examination supervision, including two U-shaped hooks, each of which is fixedly connected to a pad. The lower ends of the two U-shaped hooks are jointly fixedly connected to an adjustment mechanism one. The lower ends of adjustment mechanism one are fixedly connected to several adjustment mechanisms two. The lower ends of adjustment mechanisms two are fixedly connected to adjustment mechanism three. Several storage bags are fixedly connected to adjustment mechanisms one, two, and three. Bag caps are fixedly connected to the storage bags. The lower end of adjustment mechanism three is rotatably connected to a roller. Adjustment mechanism one and adjustment mechanism three are jointly connected to a fixing component.

[0008] Furthermore, the adjustment mechanism includes a telescopic rod fixedly connected to the lower ends of the two U-shaped hooks, and a support plate is fixedly connected between the two telescopic rods.

[0009] Furthermore, the second adjustment mechanism includes a second telescopic rod fixedly connected to the lower end of the two telescopic rods, and a second support plate fixedly connected between the two telescopic rods.

[0010] Furthermore, the adjustment mechanism three includes a support plate three fixedly connected to the lower ends of the two telescopic rods two, and connecting rods are fixedly connected to both sides of the support plate three, with rollers rotatably connected to the two connecting rods.

[0011] Furthermore, the fixing component includes a fixing block 1 fixedly connected to the support plate 3, a telescopic rod 3 fixedly connected to the fixing block 1, a tightening bolt threaded onto the telescopic rod 3, a fixing block 2 fixedly connected to the upper end of the telescopic rod 3, and the fixing block 2 fixedly connected to the support plate 1.

[0012] Furthermore, the support assembly includes two rotating shafts rotatably connected to both sides of the telescopic rod three, with a U-shaped rod connecting the two rotating shafts two together, and inclined limiting plates fixedly connected to both sides of the telescopic rod three.

[0013] Furthermore, both the storage bag and the bag cap are made of nylon, and they are fixed together by hook and loop fasteners and velour fasteners. At the same time, a cotton pad is fixedly connected to the inner wall of the storage bag.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This mobile phone holder for teaching and examination supervision is convenient for staff to move and transport. It can be placed on the ground or hung on a table or door using hooks. In the event of a tipping over, the Velcro closure prevents the phone from falling out of the holder, and the foam layer protects the phone from damage. Furthermore, after use, the overall height can be lowered for easy storage. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1 to 4 A mobile phone storage rack for teaching and examination monitoring includes two U-shaped hooks 1, each with a pad 2 fixedly connected to it. The lower ends of the two U-shaped hooks 1 are fixedly connected to an adjustment mechanism 1. The lower ends of adjustment mechanism 1 are fixedly connected to several adjustment mechanisms 2. The lower ends of adjustment mechanisms 2 are fixedly connected to adjustment mechanism 3. Several storage bags 3 are fixedly connected to adjustment mechanisms 1, 2, and 3. Bag caps 4 are fixedly connected to the storage bags 3. The lower end of adjustment mechanism 3 is rotatably connected to a roller 6. Adjustment mechanism 1 and adjustment mechanism 3 are connected to a fixing component. A support component is provided on the fixing component. A U-shaped tube clamp 7 for fixing the support component is fixedly connected to adjustment mechanism 3.

[0023] This utility model discloses a mobile phone storage holder for teaching and examination supervision. Its structure is similar to existing mobile phone storage holders, such as the one disclosed in publication number CN216291040U, which is a mobile phone storage holder for high school examination supervision. The main improvement of this utility model is that the vertical spacing between the storage bags 3 can be adjusted through the adjusting mechanism and fixing components. During use, the spacing increases, facilitating storage and retrieval; after use, the spacing decreases, thereby reducing the height of the storage holder and facilitating storage. Figures 1 to 4 As shown, in this utility model, the mobile phone storage rack for teaching and examination supervision can be dragged by the user by grasping the handle. This makes it easy to move to various locations without carrying it. In use, first, the user releases the screw 16 to restrict the telescopic rod 15, then pulls the support plate 9 upwards, causing the telescopic rod 15 to gradually lengthen. As the telescopic rod 15 lengthens, the distance between the support plate 9 and the support plate 11 increases until an upward pulling force is applied to the support plate 11, causing the telescopic rod 10 to lengthen. As the telescopic rod 10 lengthens, the distance between the support plates 11 also increases, as does the distance between the support plates 11 and the support plate 12. Then, the user tightens the screw 16. 6. The length of the telescopic rod 15 can be fixed, thereby fixing the height and position of the support plate 1 9, support plate 2 11 and support plate 3 12, thus adjusting the distance of the storage bag 3 in the vertical direction for easy storage and retrieval during use. Similarly, after use, the reverse operation can be performed to fold it up and lower the overall height for easy storage. At the same time, during use, this storage rack can be hung on a door or table using the U-shaped hook 1 and the pad 2, or the U-shaped rod 19 can be rotated outward to support the storage rack and place it on the ground.

[0024] like Figure 1 As shown, the adjustment mechanism includes telescopic rods 8 fixedly connected to the lower ends of two U-shaped hooks 1, and a support plate 9 fixedly connected between the two telescopic rods 8.

[0025] Specifically, after contacting and tightening the bolt 16 on the telescopic rod 15, the support plate 19 is pulled upward, thereby making the telescopic rod 15 gradually longer. When the telescopic rod 15 becomes longer, the distance between the support plate 19 and the support plate 21 increases until an upward pulling force is applied to the support plate 211, thereby adjusting the distance between the storage bag 3 on the support plate 19 and the storage bag 3 on the support plate 21.

[0026] like Figure 1 As shown, the second adjustment mechanism includes a second telescopic rod 10 fixedly connected to the lower ends of the two telescopic rods 8, and a second support plate 11 fixedly connected between the two telescopic rods 10.

[0027] Specifically, an upward pulling force is continuously applied to the second support plate 11, which makes the second telescopic rod 10 longer. When the second telescopic rod 10 becomes longer, the distance between the second support plate 11 and the second support plate 11 also becomes longer, thereby adjusting the distance between the storage bags 3 on the upper and lower support plates 12.

[0028] like Figure 1 As shown, the adjustment mechanism includes a support plate 12 fixedly connected to the lower ends of the two telescopic rods 10. Connecting rods 13 are fixedly connected to both sides of the support plate 12, and the roller 6 is rotatably connected to the two connecting rods 13.

[0029] Specifically, by continuing to apply an upward pulling force, the distance between support plate 2 11 and support plate 3 12 will also increase, thereby adjusting the distance between the storage bag 3 on support plate 3 12 and the storage bag 3 on support plate 2 11.

[0030] like Figure 2 As shown, the fixing assembly includes a fixing block 14 fixedly connected to the support plate 12, a telescopic rod 15 fixedly connected to the fixing block 14, a tightening bolt 16 threadedly connected to the telescopic rod 15, a fixing block 2 17 fixedly connected to the upper end of the telescopic rod 15, and the fixing block 2 17 fixedly connected to the support plate 9.

[0031] Specifically, by releasing the fixing effect of the tightening bolt 16 on the telescopic rod 15, the support plate 9 can be pulled upwards, thereby gradually lengthening the telescopic rods 8 and 10. This adjusts the distance between the support plates 9, 11, and 12, thus adjusting the spacing between the storage bags 3 in the vertical direction. After adjustment, tightening the tightening bolt 16 fixes the telescopic rod 15, thereby fixing the height and position of each row of storage bags 3 for easy storage and retrieval of mobile phones. After use, the reverse operation is performed to fold them up, reducing the height of the storage rack for easier storage.

[0032] like Figure 4 As shown, the support assembly includes two rotating shafts 18 rotatably connected to both sides of the telescopic rod 15, and a U-shaped rod 19 is connected between the two rotating shafts 18. Inclined limiting plates 20 are fixedly connected to both sides of the telescopic rod 15.

[0033] Specifically, after adjusting the height of the storage rack, the U-shaped rod 19 can be rotated outward to disengage from the U-shaped tube clamp 7. Continue to rotate until it comes into contact with the inclined limiting plate 20. The triangular support is used to support the storage rack, allowing it to be placed on the ground.

[0034] like Figure 3As shown, the storage bag 3 and the bag cover 4 are both made of nylon, and they are fixed together by hook and loop fasteners and velvet fasteners. At the same time, a cotton pad 5 is fixedly connected to the inner wall of the storage bag 3.

[0035] Specifically, the cotton pad 5 reduces the impact on the phone when the storage rack falls over, thus protecting the phone and making it less prone to damage.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
