Description
Technical Field
[0001] This utility model relates to the field of lighting structure technology, and in particular to an upper and lower cover support structure. Background Technology
[0002] Currently, lighting products on the market generally have two types of upper and lower cover support structures: one is a two-section retractable support method similar to aluminum alloy windows (such as...). Figure 7 and Figure 8 (As shown). The disadvantages are its complex structure, high cost, and unattractive appearance. Another type is a manual support system similar to the previous car hood design. The disadvantage is that it cannot be closed with one hand; when opening the hood, one hand supports the hood while the other hand uses the support rod to place it in the fixed position (e.g.,...). Figure 6 As shown, it requires two hands to operate and is extremely unsightly. For various products with top and bottom covers that are intended to support the top cover, single-handed operation can effectively ensure safety.
[0003] Single-handed operation is crucial for products used at heights outdoors (such as streetlights, garden lights, and other similar products), as it involves the personal safety of installers at heights. For those working at heights, being able to operate with one hand frees up the other, significantly enhancing their safety.
[0004] Therefore, there is an urgent need for a low-cost, aesthetically pleasing, and one-handed top and bottom cover support structure. Utility Model Content
[0005] The purpose of this utility model is to provide an upper and lower cover support structure to solve the problems of low safety and unsightly appearance of the existing upper and lower cover support structures.
[0006] To achieve the above objectives, the specific technical solution of the upper and lower cover support structure of this utility model is as follows:
[0007] A top and bottom cover support structure includes a metal base and a metal rod. The metal base has an elongated slot for moving the metal rod. The end of the slot has a small hook for holding the metal rod. The end of the metal rod near the elongated slot has a small bend for preventing it from falling off. One end of the metal rod passes through the elongated slot of the metal base, and the other end has a large bend for fixing it to the top cover.
[0008] Furthermore, the metal base is an L-shaped metal strip, and the strip slot is located on one side of the wider side of the metal base.
[0009] Furthermore, the long slot is provided with a limiting slot near the entrance of the small hook slot to narrow the slot gap, and the metal rod enters the small hook slot through the limiting slot to be fixed.
[0010] Furthermore, the metal base is provided with several through holes.
[0011] Furthermore, the large bend of the metal rod is fixed to the upper cover by a fixing component, which is an upper and lower pressing structure, and a channel for the large bend of the metal rod to pass through is provided in the middle of the fixing component.
[0012] Furthermore, the metal rod is provided with fixing caps at the large and small bends to prevent it from falling off.
[0013] The upper and lower cover support structure provided by this utility model has the following advantages:
[0014] One-handed operation: opening and closing can be completed simply by pushing the metal rod, making it especially suitable for high-altitude work scenarios.
[0015] Safety features include a safety locking mechanism and a small bend, which provide double protection against accidental closure caused by strong winds or vibrations.
[0016] Cost and aesthetics: The integrated metal structure reduces the number of parts, resulting in a clean appearance that is easy to integrate with products. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.
[0027] See Figure 1-5 This utility model provides a top and bottom cover support structure suitable for scenarios requiring one-handed operation and balancing safety and aesthetics (such as high-altitude lighting fixtures, outdoor equipment, etc.). It includes a metal base 1 and a metal rod 2. The metal base 1 is L-shaped with a long slot 3 along its wider side, and a limiting latch 32 and a small hook groove 31 at its end. Through holes 11 are evenly distributed on both sides of the base for connection to the top and bottom covers 5. One end of the metal rod 2 has a small anti-detachment bend 21 that passes through the long slot 3; the other end has a large U-shaped bend 22, which is fixed to the top cover 4 by a fixing component 6. The metal rod 2 slides along the long slot 3. When the top cover 4 is opened, the metal rod 2 slides to the small hook groove 31 and locks itself through the limiting latch 32. A gentle push with one hand unlocks the metal rod 2, achieving closure.
[0028] In one embodiment, the metal base 1 is made of stainless steel in an L-shaped strip; the wider side is set in the vertical direction and the narrower side is set in the horizontal direction. The wider side of the metal base 1 has a long strip groove 3, and the end has a limiting slot 32 that is lower than the width of the long strip groove 3 and a small hook groove 31 for fixing the metal rod 2. Through holes 11 for fixing are opened on both sides of the narrower side and on the side of the wider side away from the small hook groove 31 on the metal base 1. One end of the metal rod 2 is set as a small bend 21 structure, and the other end is set as a large bend structure. The small bend 21 is welded to the end near the long strip groove 3, and the U-shaped end is fixed to the upper cover 4 by a fixing component 6. The upper end of the fixing component 6 is provided with fixing bolt holes for fixing to the lower cover 5.
[0029] During installation, first insert the large bend 22 of the metal rod 2 into the long slot 3, and pull it until the bent part of the small bend 21 is inserted into the long slot 3. At this time, since the bent part of the small bend 21 is relatively narrow, it can be inserted into the long slot 3 and moved back and forth. Then, insert the bent part of the large bend 22 into the fixing bolt hole of the fixing component 6, and fix it to the upper cover 4 by pressing it with the upper pressure plate of the fixing component 6.
[0030] When in use, since the upper cover 4 and the lower cover 5 are usually closed, when the operator opens the upper cover 4 with one hand, the metal rod 2 also moves in the long slot 3 of the metal base 1. When the upper cover 4 is fully opened, the metal rod 2 also moves to the end of the long slot 3 and finally gets stuck in the small hook slot 31 through the limiting slot 32.
[0031] When the top cover 4 encounters strong winds, it experiences downward pressure. At this time, the small hook groove 31 will tightly hold the metal rod 2 in place to prevent it from falling backward and thus preventing a safety accident. When the worker pushes it upward again with one hand, the metal rod 2 will leave the small hook area. Then, when the cover is closed downward, the metal rod 2 will slide out of the small hook groove 31 area along the rounded corner of the limiting latch 32 and return to the long strip groove 3 until it is completely closed.
[0032] This invention effectively solves the inconvenience and safety issues caused by the need for operators to use both hands in existing support devices. It also further addresses the aesthetic problems of existing support device structures and the high costs resulting from their complexity.
[0033] Example 2
[0034] The difference from the above embodiment is that the small bend 21 of the metal rod 2 is provided with a fixing cap 23 for preventing it from falling off.
[0035] Example 3
[0036] The difference from the above embodiment is that both the small bend 21 and the large bend 22 of the metal rod 2 are provided with fixing caps 23 for preventing slippage.
[0037] In summary, this utility model provides a support frame for opening and closing the upper and lower covers 5 with one hand. The L-shaped metal base 1 and the metal rod 2 work together to achieve efficient operation and safety. The metal base 1 has a long slot 3 along its wide side, with a limiting latch 32 and a small hook slot 31 at the end. Combined with the anti-detachment small bends 21 at both ends of the metal rod 2, this ensures that the upper cover 4 is firmly locked when opened and slides back to its original position with a gentle push of one hand when closed, significantly improving the safety of high-altitude operations. The integrated metal design reduces the number of parts and effectively lowers production costs.
[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
