Description

Technical Field

[0001] The present invention relates to the technical field of road administration facilities, and in particular to a column with a ladder for storing and a street lamp using the column. Background Art

[0002] With the progress of urbanization, there are various types of street lights on the roads, such as lighting lamps, signal lights, snapshot fill lights, etc. These street lights are exposed to the sun, wind and rain for a long time, and often malfunction and need to be repaired or replaced with parts, which requires emergency treatment by road maintenance or power workers. Among them, lighting lamps are heavy in maintenance due to their large number, wide distribution and fragile bulbs.

[0003] Conventional technical solutions typically require ladders or scaffolding to replace or repair shorter streetlights. However, if multiple locations require repair, the ladders and scaffolding are difficult to transport and time-consuming and labor-intensive to set up, significantly reducing troubleshooting efficiency. Higher streetlights also require specialized equipment like lifts, which can severely impact driving safety and smoothness on roads with heavy traffic, potentially leading to accidents or even traffic paralysis.

[0004] Some emerging technologies also include streetlights with attached ladders, such as Chinese patents CN201810760254.1 and CN201921262979.4, which demonstrate climbable streetlights. However, the ladders can only be hung on the outside of the streetlights for a long time, which is obviously very inconvenient in actual use and poses a huge safety hazard. To this end, some patents have made some improvements and proposed hidden ladders, such as Chinese patent CN201810985101.7. The ladders in these designs only consist of horizontal bars that can be inserted into or pulled out of the vertical bars horizontally. Putting aside the stability and safety of the ladder design, the practice of deliberately thickening the vertical bars to hide the horizontal bars is obviously not in line with the actual needs of road administration.

[0005] Therefore, the field of road facilities technology urgently needs a lamp post that has a ladder attached while maintaining the basic structure of the existing street lamp and that is safe, reliable and easy to store. Summary of the Invention

[0006] The present invention overcomes the defects of the prior art and provides a lamp post which, while maintaining the basic structure of the existing street lamp, is equipped with a ladder which is safe, reliable and easy to store.

[0007] The present invention is achieved through the following technical solutions:

[0008] A column with a storage ladder comprises a hollow column fixed to a mounting surface, a side surface of the column being provided with a paving groove extending axially, a vertical plate being provided at the paving groove and being able to fit with and cover the outer wall of the column, a plurality of cross bars being provided between the vertical plate and the column, one end of the cross bar passing through the paving groove and being hinged to the inner wall of the column, the other end of the cross bar being rotatably connected to the vertical plate, and the lower end of the vertical plate touching the ground when each of the cross bars is in a horizontal position.

[0009] Furthermore, a first fastening assembly is provided at the lower part of the vertical plate or at the position of the column side wall corresponding to the lower part of the vertical plate when the vertical plate is in affixed to the column, and a second fastening assembly is provided at the upper part of the vertical plate or at the position of the column side wall corresponding to the upper part of the vertical plate when the vertical plate is in affixed to the column.

[0010] Furthermore, the first fastening assembly includes a first rotating plate and a second rotating plate hinged to the two side edges of the lower part of the vertical plate respectively. The first rotating plate and the second rotating plate can be ringed on the outer side wall of the column in an embraced state. A locking mechanism is provided between the extending end of the first rotating plate away from the vertical plate and the extending end of the second rotating plate away from the vertical plate.

[0011] Furthermore, the locking mechanism includes a first buckle located at the extending end of the first rotating plate and a second buckle located at the extending end of the second rotating plate, and fasteners are inserted through the first buckle and the second buckle.

[0012] Furthermore, the second fastening assembly includes a card plate located on the outer side wall of the column, the card plate corresponds to the upper part of the vertical plate when the vertical plate is in contact with the column, the upper edge of the card plate is fixedly connected to the outer side wall of the column, and a card slot is formed between the card plate and the outer side wall of the column for the upper end of the vertical plate to be inserted.

[0013] Furthermore, the width of the clamping plate is greater than the width of the vertical plate, the vertical edges on both sides of the clamping plate are fixedly connected to the outer side walls of the pillars, and the opening thickness of the clamping slot gradually decreases from bottom to top.

[0014] Furthermore, the hole on each of the cross bars used for achieving rotational connection with the vertical plate is an oblong hole, and the length of the oblong hole gradually decreases as the height of the cross bar increases.

[0015] Furthermore, the inner side wall of the column is provided with a reinforcing rib extending in the axial direction, and the reinforcing rib is located between the hinge point between the cross bar and the column and the clearance groove.

[0016] Furthermore, a support leg assembly is provided at the lower portion of the vertical board, and the support leg assembly includes a support leg block fixedly connected to the inner side wall of the vertical board, a support rod is threadedly connected to the support leg block along the vertical direction, and a foot pad is provided at the lower end of the support rod.

[0017] The present invention also provides a street lamp using the above-mentioned column with a storage ladder, wherein a lamp pole is provided on the upper part of the column, and a lamp head is provided on the lamp pole; the recess is located on the side of the column close to the lamp head.

[0018] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0019] The side walls of the hollow columns of the present invention are provided with clearance grooves, which allow the crossbars to be tilted and stored in the columns. The two ends of each crossbar are respectively connected to the vertical plates and the inner side walls of the columns, thereby forming a foldable ladder. In the unfolded state, the lower ends of the vertical plates touch the ground, and the operator can bear force at both ends of the crossbars when in use, which is stable and safe. In the stowed state, the vertical plates can cover the clearance grooves and fit closely with the outer side walls of the columns, making them neat and unobtrusive. Even more clever is that the upper and lower parts of the vertical plates are both provided with fastening components, especially the fastening components on the upper part. After the user descends to the ground, the upper end of the vertical plate can still be fixed. Once the lower end is fixed, the entire ladder is completely fixed. Most importantly, the crossbars are not horizontally extended or pushed and pulled, but are tilted and stored in the columns. There is no need to deliberately thicken the columns, which ensures the beautiful appearance of the lamp posts and controls the production costs of the lamp posts. It has great promotion value and broad application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with examples and drawings. The exemplary embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0047] A column with a storage ladder comprises a hollow column 1 fixed to a mounting surface, a side surface of the column 1 being provided with a paving groove extending in the axial direction, a vertical plate 4 being provided at the paving groove and being able to fit with the outer wall of the column 1 and cover the paving groove, a plurality of cross bars 5 being provided between the vertical plate 4 and the column 1, one end of the cross bar 5 passing through the paving groove and being hinged to the inner wall of the column 1, the other end of the cross bar 5 being rotatably connected to the vertical plate 4, and the lower end of the vertical plate 4 touching the ground when each of the cross bars 5 is in a horizontal position. It can be understood that a clearance groove is provided, which allows the crossbar 5 to be tilted and stored in the column 1, thereby forming a foldable ladder. In the unfolded state, the lower end of the vertical board 4 touches the ground. When the operator is in use, both ends of the crossbar 5 can be stressed, which is stable and safe. In the stored state, the vertical board 4 can cover the clearance groove and fit with the outer wall of the column 1, which is neat and not protruding. The crossbar 5 is not horizontally extended or pushed and pulled, but is tilted and stored in the column 1. There is no need to deliberately thicken the column 1, which ensures the beautiful appearance of the lamp post and controls the production cost of the lamp post.

[0048] Furthermore, a first fastening assembly 7 is provided on the lower portion of the riser 4 or on the side wall of the column 1 corresponding to the lower portion of the riser 4 when the riser 4 is in contact with the column 1, and a second fastening assembly 8 is provided on the upper portion of the riser 4 or on the side wall of the column 1 corresponding to the upper portion of the riser 4 when the riser 4 is in contact with the column 1. It is understandable that the difficulty in providing a retractable ladder lies in the problem of storing the ladder after use. While a person can operate the ladder from a high position, they cannot store it. After descending, they cannot reach the upper portion of the ladder without the aid of tools. If tools are used, then providing a retractable ladder is meaningless. However, the present technical solution provides a first fastening assembly 7 and a second fastening assembly 8 on the lower and upper portions of the riser 4, respectively. In particular, the second fastening assembly 8 on the upper portion has a very clever structure. After the user descends to the ground, the upper end of the riser 8 can still be fixed. Once the lower end of the riser 8 is fixed, the entire ladder is completely fixed.

[0049] Furthermore, the second fastening assembly 8 includes a card plate located on the outer side wall of the column 1, and the card plate corresponds to the upper part of the vertical plate 4 when the vertical plate 4 is in contact with the column 1. The upper edge of the card plate is fixedly connected to the outer side wall of the column 1, and a card slot for the upper end of the vertical plate 4 to be inserted is formed between the card plate and the outer side wall of the column 1. Furthermore, the width of the card plate is greater than the width of the vertical plate 4, and the vertical edges on both sides of the card plate are fixedly connected to the outer side wall of the column 1, and the opening thickness of the card slot gradually decreases from bottom to top. Furthermore, in order to adapt to the card slot, the hole on each of the cross bars 5 used to realize the rotational connection with the vertical plate 4 is an oblong hole, and the length of the oblong hole gradually decreases as the height of the cross bar 5 increases. It can be understood that, if Figures 6 to 12 As shown, the plurality of crossbars 5, vertical plates 4 and uprights 1 do not form a strict parallelogram, but the action points of the crossbars 5 and the vertical plates 4 have a certain movable space along the length direction of the crossbars 5, and the lower the crossbars 5 are, the larger the movable space of the action points is. The best choice is to arrange the lengths of adjacent oblong holes in sequence to form an arithmetic progression, and the action points of the top layer can be circular holes. In this way, when stored, the vertical plates 5 and the uprights 1 are no longer in a parallel relationship, but the upper ends of the vertical plates 4 first contact the outer walls of the uprights 1, so that the upper ends of the vertical plates 4 can be inserted obliquely into the slots. Because the thickness of the slot opening is smaller at the top and larger at the bottom, as the vertical plates 4 get closer and closer to the uprights 1, the upper ends of the vertical plates 4 are gradually pressed tighter and tighter. After the lower ends of the vertical plates are fixed by the first fixing components 7, the storage and fixation of the entire ladder are realized. Figures 14 to 20 shown.

[0050] Furthermore, the first fastening assembly 7 includes a first rotating plate and a second rotating plate respectively hinged to both sides of the lower portion of the vertical plate 4, the first rotating plate and the second rotating plate can be looped around the outer wall of the column 1 in an embracing state, and a locking mechanism is provided between the extending end of the first rotating plate away from the vertical plate 4 and the extending end of the second rotating plate away from the vertical plate 4. Furthermore, the locking mechanism includes a first buckle located at the extending end of the first rotating plate and a second buckle located at the extending end of the second rotating plate, and fasteners are passed through the first buckle and the second buckle. It is understandable that there are too many optional parts, mechanisms, and devices for fixing the lower end of the vertical plate 4, such as bolts, nuts, pins, buckles, locks, etc., so they will not be elaborated here, and a preferred embodiment is provided, such as Figure 2 、 Figure 4 、 Figure 22 As shown, the first and second rotating plates can be rotated in the width direction of the risers 4 when the ladder is in the extended state, thereby improving the stability of the risers 4 and the ladder. The distance between the extended ends of the first and second rotating plates can be slightly larger, that is, they cannot be completely closed, so that fasteners such as bolts and nuts, tightening locks, etc. can be used to adjust the tension and ensure tightness.

[0051] Furthermore, the inner sidewall of the column 1 is provided with an axially extending reinforcing rib 6, located between the hinge point and the clearance groove between the crossbar 5 and the column 1. It is understood that the provision of the clearance groove along the axis of the column 1 has a certain impact on the structural strength of the column 1. Therefore, the reinforcing rib 6 is provided to reinforce the column 1. In a preferred embodiment, two reinforcing ribs 6 are provided, one on each side of the crossbar 5, and the cross-section of each reinforcing rib 6 is flat, curved, or V-shaped.

[0052] Furthermore, a support foot assembly 9 is provided at the lower portion of the vertical plate 4, and the support foot assembly 9 includes a support foot block fixedly connected to the inner wall of the vertical plate 4, a support rod is threadedly connected in the vertical direction in the support foot block, and a foot pad is provided at the lower end of the support rod. It is understandable that due to the different installation processes of the column 1, when the crossbar 5 is in a horizontal state, the lower end of the vertical plate 4 may be some height away from the ground, or the column 1 is relatively close to the edge of the road during installation, and the vertical plate 4 is located under the curb after the ladder is unfolded. Therefore, a support foot assembly 9 is provided at the lower portion of the vertical plate 4, and the specific structure can have a variety of shapes, as long as the width is smaller than the width of the clearance slot. It is feasible to be able to be accommodated in the column. If Figure 5 As shown, there is also a preferred small structure that can improve the stability of the ladder. A support block is provided below the hinge point between the crossbar 5 and the inner wall of the column 1. One side of the support block is fixedly connected to the inner wall of the column 1, and the top is provided with a platform that supports the crossbar 5. After the support block is provided, the crossbar 5 can have an additional fulcrum when it is unfolded and used, and can be better maintained in a horizontal position. The level here refers to a rough level, not a precise level.

[0053] A street lamp employing the aforementioned column with a stowable ladder comprises a lamp post 2 disposed on the upper portion of the column 1, which is provided with a lamp holder 3. The recess is located on the side of the column 1 near the lamp holder 3. It is understood that the recess is located on the side of the column 1 near the lamp holder 3, meaning that when the ladder is deployed, it is located below the lamp holder 3 on the lamp post 2, making it more convenient and easy to operate. The lamp holder 3 is a lamp in a broad sense, and can be the most common lighting lamp, a red, green, and yellow signal light, a snapshot fill light, or even a column for mounting cameras, monitors, signal base stations, and other equipment.

[0054] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
