Description

Technical Field

[0001] This utility model relates to the field of intelligent folding ladder equipment technology, specifically to a folding portable communication base station maintenance ladder. Background Technology

[0002] Maintenance ladders are indispensable tools in the daily maintenance and repair of communication base stations. Traditional maintenance ladders for communication base stations are usually large and have a fixed structure, occupying a lot of space during transportation and storage, and are extremely inconvenient to move. In addition, existing maintenance ladders lack effective limiting measures for the opening angle, posing a risk of over-opening or accidental folding. This not only affects the normal conduct of maintenance work but may also pose a serious threat to the personal safety of maintenance personnel. Existing maintenance ladders that can limit the opening angle only connect the two sides of the ladder through hinges, which can only provide support when the ladder is opened to its maximum limited angle. At other times, they cannot provide support, leaving the ladder at risk of accidental over-opening or accidental folding. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a foldable portable communication base station maintenance ladder. The first ladder and the second ladder are hinged to achieve the folding function, which reduces the volume of the maintenance ladder when not in use, making it convenient for transportation and storage. The setting of the limiting component can effectively limit the opening angle of the first ladder and the second ladder, preventing the ladder from being over-opened or accidentally folded.

[0004] A foldable portable communication base station maintenance ladder includes a first ladder and a second ladder, the upper ends of the first ladder and the second ladder are hinged together, and a limiting component is connected to one side of the first ladder and the second ladder respectively. The limiting component can limit the opening of the first ladder and the second ladder to a specific angle.

[0005] Furthermore, the limiting assembly includes a limiting rod, a limiting shaft, a first sleeve, a first stop, a second stop, a second sleeve, and a connecting shaft. The connecting shaft is fixedly installed on one side of the first ladder, and the connecting shaft is rotatably connected to one end of the limiting rod. A limiting shaft is fixedly installed on one side of the second ladder corresponding to the position of the connecting shaft. A positioning groove is opened on the lower side of the end of the limiting rod rotatably connected to the connecting shaft. A set of evenly arranged slots is opened on the lower side of the other end of the limiting rod. Both the slots and the positioning grooves can lock the limiting shaft. A second sleeve is fixedly installed on the lower side of one end of the limiting rod, and the second sleeve is screwed to the second stop. A first sleeve is fixedly installed on the lower side of the other end of the limiting rod, and the first sleeve is screwed to the first stop.

[0006] Furthermore, one end of the second stop can be placed on the lower side of the positioning groove.

[0007] Furthermore, the first stop can be positioned on the lower side of the slot.

[0008] Furthermore, the limiting rod includes a first connecting rod and a second connecting rod. One end of the first connecting rod corresponds to one end of the second connecting rod. The other end of the first connecting rod is rotatably connected to the connecting shaft. The opposite ends of the first connecting rod and the second connecting rod are respectively fixed with connecting blocks. The connecting blocks are rotatably connected. The other end of the second connecting rod has the slot on its lower side, and the first connecting rod has the positioning groove on its lower side.

[0009] Furthermore, the card slot and the positioning slot are the same size, and the limiting shaft can be inserted into both of them.

[0010] Furthermore, when the first ladder and the second ladder are in the closed state, the limiting shaft can be engaged in the positioning groove.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] A foldable portable communication base station maintenance ladder includes a first ladder 1 and a second ladder 2. The upper ends of the first ladder 1 and the second ladder 2 are hinged together. A limiting component is connected to one side of the first ladder 1 and the second ladder 2 respectively. The limiting component can limit the opening of the first ladder 1 and the second ladder 2 to a specific angle.

[0024] The first ladder 1 and the second ladder 2 are hinged at the top to achieve a foldable function. The limiting component uses a mechanical structure to limit the opening angle of the two ladders, so that the ladders can maintain a stable open state during use. The limiting component ensures that the ladders remain stable when opened to a specific angle, preventing the ladders from being over-opened or accidentally folded, and ensuring the safety of the user.

[0025] The limiting assembly includes a limiting rod 3, a limiting shaft 4, a first sleeve 5, a first stop 6, a second stop 7, a second sleeve 8, and a connecting shaft 9. The connecting shaft 9 is fixedly installed on one side of the first ladder 1, and the connecting shaft 9 is rotatably connected to one end of the limiting rod 3. The limiting shaft 4 is fixedly installed on one side of the second ladder 2 corresponding to the position of the connecting shaft 9. A positioning groove 302 is opened on the lower side of the end of the limiting rod 3 that is rotatably connected to the connecting shaft 9. A set of evenly arranged slots 301 are opened on the lower side of the other end of the limiting rod 3. Both the slots 301 and the positioning grooves 302 can lock the limiting shaft 4. The second sleeve 8 is fixedly installed on the lower side of one end of the limiting rod 3. The second sleeve 8 is screwed to the second stop 7. One end of the second stop 7 can be placed on the lower side of the positioning groove 302. The first sleeve 5 is fixedly installed on the lower side of the other end of the limiting rod 3. The first sleeve 5 is screwed to the first stop 6.

[0026] The first stop 6 can be placed on the lower side of the slot 301.

[0027] The connecting shaft 9 is fixed on the first ladder 1 and serves as the rotation center of the limiting rod 3; the limiting shaft 4 is fixed on the second ladder 2 and cooperates with the positioning groove 302 and the slot 301 on the limiting rod 3 to achieve angle limiting. The first and second sleeves 8 are screwed to the first and second stop rods 7 respectively. By rotating the stop rods, they can be placed under the slot 301 or the positioning groove 302 to prevent the limiting shaft 4 from coming out of the groove. Through simple rotation and screwing actions, the opening angle of the ladder can be accurately limited and locked, which is convenient to use and enhances the stability of the ladder.

[0028] In another embodiment, the limiting rod 3 includes a first connecting rod 31 and a second connecting rod 32. One end of the first connecting rod 31 corresponds to one end of the second connecting rod 32. The other end of the first connecting rod 31 is rotatably connected to the connecting shaft 9. The opposite ends of the first connecting rod 31 and the second connecting rod 32 are respectively fixed with connecting blocks 33, which are rotatably connected. The other end of the second connecting rod 32 has the slot 301 on its lower side, and the first connecting rod 31 has the positioning groove 302 on its lower side.

[0029] The limiting rod 3 includes a first connecting rod 31 and a second connecting rod 32, which are rotatably connected by a connecting block 33. This allows the limiting rod 3 to achieve the angle limiting function while also having better flexibility and adjustability. When the ladder is in the closed state, it can prevent the limiting rod 3 from being too long and making it inconvenient to store. It also makes it easy to fold the first connecting rod 31 and the second connecting rod 32 for storage. Although this embodiment achieves the function of easy storage through the rotatable connection of the first connecting rod 31 and the second connecting rod 32, this embodiment is not as supportive as the first embodiment where the limiting rod 3 is a one-piece straight rod. The first embodiment has a stronger support than this embodiment, but this embodiment is easier to store.

[0030] The slots 301 and 302 are the same size, and the limiting shaft 4 can be engaged in both. The fact that the slots 301 and 302 are the same size and can both engage the limiting shaft 4 ensures stable engagement of the limiting shaft 4 in different slots, resulting in consistent limiting effect when the ladder is opened to different angles.

[0031] When the first ladder 1 and the second ladder 2 are closed, the limiting shaft 4 can engage with the positioning groove 302. In this closed state, the limiting shaft 4 engages with the positioning groove 302, forming an initial locked state to prevent the ladders from accidentally opening when not in use. When the ladders are in use and the first ladder 1 and the second ladder 2 need to be opened, the limiting shaft 4 can engage with the slot 301 at the required angle, thus limiting the movement of the first ladder 1 and the second ladder 2.

[0032] Both the first ladder 1 and the second ladder 2 have textured surfaces on their footings to increase friction and improve stability when used by the user.

[0033] The method of using this utility model is as follows: Example 1: When the maintenance ladder is in the closed and retracted state, the limiting shaft 4 is engaged in the positioning groove 302 at one end of the limiting rod 3. At this time, the second stop 7 is screwed to the lower side of the positioning groove 302 through the second sleeve 8 to prevent the limiting shaft 4 from coming out. When the maintenance personnel use it, they first rotate the second stop 7 to disengage it from the lower side of the positioning groove 302, then pull the limiting rod 3 upwards to separate the positioning groove 302 and the limiting shaft 4. Holding the first ladder 1 and the second ladder 2, they unfold them outwards. During the unfolding process, according to actual usage needs, the first ladder 1 and the second ladder 2 are opened to a specific angle. When the desired angle is reached, rotate the limiting rod 3 so that the limiting shaft 4 engages in the corresponding slot 301 at the other end of the limiting rod 3. Then tighten the first stop rod 6 so that it is placed under the slot 301, firmly locking the limiting shaft 4 in the slot 301. This achieves stable limiting of the opening angle of the first ladder 1 and the second ladder 2, at which point the maintenance ladder can be put into use. After the maintenance work is completed, rotate the first stop rod 6 and the limiting rod 3 so that the limiting shaft 4 disengages from the slot 301. Then, bring the first ladder 1 and the second ladder 2 together inward. Pull the limiting rod 3 so that the limiting shaft 4 engages in the positioning slot 302 again. Finally, tighten the second stop rod 7 to complete the storage of the maintenance ladder.

[0034] In Embodiment 2, when the maintenance ladder is closed and stored, the limiting shaft 4 is engaged in the positioning groove 302 of the first connecting rod 31, and the second stop 7 is fixed on the lower side of the positioning groove 302. The first connecting rod 31 and the second connecting rod 32 are in a folded state. Since the limiting rod 3 is rotatably connected by the first connecting rod 31 and the second connecting rod 32 through the connecting block 33, the first connecting rod 31 and the second connecting rod 32 need to be unfolded to a straight state before unfolding (to facilitate subsequent alignment with the ladder angle). Then, rotate the second stop 7 so that it no longer blocks the lower side of the positioning groove 302. Pull the first connecting rod 31 to disengage the positioning groove 302 from the limiting shaft 4. Hold the first ladder 1 and the second ladder 2 and unfold them outwards. According to the angle required by the actual use scenario, rotate the limiting rod 3 so that the limiting shaft 4 is engaged in the corresponding slot 301 on the second connecting rod 32. Then tighten the first stop 6 to fix the limiting shaft 4. After completing the maintenance task, rotate the first stop bar 6 so that it no longer blocks the slot 301 corresponding to the limiting shaft 4. Rotate the limiting rod 3 to disengage the limiting shaft 4 from the slot 301. Close the first ladder 1 and the second ladder 2. Due to the foldable nature of the limiting rod 3, rotate and fold the first connecting rod 31 and the second connecting rod 32 around the connecting block 33 to reduce the space occupied by the limiting rod 3. Finally, let the limiting shaft 4 engage with the positioning slot 302 and tighten the second stop bar 7 to complete the storage of the maintenance ladder.

[0035] The above-disclosed embodiments are merely specific examples of this utility model. However, this utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
