Description

Technical Field

[0001] This utility model relates to the field of ladder technology, specifically a simple ladder structure distribution structure. Background Technology

[0002] Ladders are mainly used as auxiliary tools for short-distance inclined or vertical climbing, helping operators reach higher places. Simple ladders usually consist of a ladder frame and steps, and are mostly used for temporary or low-frequency climbing needs.

[0003] Currently, ladders still have some shortcomings, such as traditional ladders not being able to easily adjust the width of the ladder to suit different widths of construction grids.

[0004] To overcome the problem of inconvenient adjustment of ladders, a prior art Chinese patent (publication number: CN222716828U) discloses an adjustable ladder for space frame construction. It includes: a suspension rod comprising two spaced-apart sections, each with a hook for connecting to the construction space frame; an adjusting member located between the two sections of the suspension rod and connected to each section; the adjusting member extending and retracting along the line connecting the two sections; and a ladder rod with a connecting member at its top that communicates with the suspension rod. Both sections of the suspension rod have hooks for connecting to the construction space frame or other objects requiring suspension. The adjusting member is horizontally connected to the two sections, allowing for width adjustment by adjusting the length of the two sections extending into or retracting into the adjusting member. Alternatively, the adjusting member can be used simply as a telescopic rod. This allows the ladder to adapt to different widths of construction space frames or other objects requiring suspension during construction, thus improving compatibility.

[0005] However, the ladders currently in use still have some shortcomings. In the aforementioned document, the width of the ladder is adjusted by using the adjustable parts as telescopic rods. However, simple ladders are mainly used for temporary climbing needs. They are inconvenient to store after use and are also inconvenient to maintain after damage. Therefore, the existing structure needs to be improved. Utility Model Content

[0006] The purpose of this utility model is to provide a simple ladder structure distribution structure to solve the problems of inconvenient maintenance and storage of ladders mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a simple ladder structure distribution structure, including a first ladder, a second ladder connected to the bottom of the first ladder, and fixing components fixed to the back of both the first ladder and the second ladder.

[0008] The second ladder has a fixed cylinder symmetrically fixed at the top, the first ladder slides through the fixed cylinder, and a guide block is fixed inside the fixed cylinder. A locking groove is also opened through the inside of the fixed cylinder. The fixed cylinder is equipped with a disassembly and assembly mechanism to facilitate ladder maintenance.

[0009] Furthermore, the disassembly and assembly mechanism includes a compression block fixed to the side of the fixed cylinder. The compression block is made of rubber. A guide groove is provided on the side of the first ladder. The guide groove and the guide block are slidably connected.

[0010] Furthermore, a telescopic groove is provided on the other side of the first ladder, and a telescopic block is connected inside the telescopic groove by a spring. The telescopic block is engaged with the engaging groove.

[0011] Furthermore, a rotating mechanism is provided on the outside of the fixed cylinder to improve the installation stability of the second ladder and the first ladder. The rotating mechanism includes two rotating rods that rotate symmetrically on the side of the fixed cylinder via a rotating axis. An external rod is symmetrically fixed on the outside of the first ladder, and the end of the external rod is connected to a rubber protective sleeve.

[0012] Furthermore, the bottom of the first ladder and the external rod are both fixed with fixing blocks, and the ends of the fixing blocks and the rotating rod are provided with through holes, and pins are slidably connected through the two through holes.

[0013] Furthermore, a telescopic block two is slidably connected through the inner side of the pin, and a spring is connected between the telescopic block two and the pin.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This simple ladder structure features a distribution structure where pressing a rubber extrusion block deforms it, compressing the first telescopic block and causing it to slide within the telescopic groove and locking groove, thus compressing the spring. Pulling down the second ladder causes the fixed cylinder to move downward, and the guide block slides within the guide groove. After sliding out, the fixed cylinder separates from the first ladder, achieving separation of the two ladders. This facilitates storage and subsequent replacement of parts, reducing usage costs.

[0015] 2. It is equipped with a squeezing block, which can squeeze the telescopic block more accurately. Compared with pressing with your fingers, it is more efficient, has more contact surface, and is therefore less strenuous.

[0016] 3. An external rod is provided. The rubber protective sleeve at the end of the external rod can prevent the hard material of the external rod from causing serious impact to other parts, and can also avoid injury caused by accidental contact by personnel.

[0017] 4. A rotating rod is provided. The symmetrical rotating rod can improve the stability of the connection between the first and second ladders after positioning, thereby ensuring the stress condition of the first and second ladders and ensuring the quality of climbing the ladder.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1, such as Figures 1-3 The present invention provides the following technical solution to address the problems of inconvenient maintenance and storage of ladders: A disassembly and assembly mechanism is disclosed, comprising a first ladder 1, a second ladder 2 connected to the bottom of the first ladder 1, fixing members 3 fixed to the back of both the first ladder 1 and the second ladder 2, and fixing cylinders 101 symmetrically fixed to the top of the second ladder 2. The first ladder 1 slides through the fixing cylinder 101, and a guide block 102 is fixed to the inner side of the fixing cylinder 101. A through-hole 103 is provided, and a disassembly and assembly mechanism for easy ladder maintenance is provided inside the fixed cylinder 101. The disassembly and assembly mechanism includes a compression block 104 fixed to the side of the fixed cylinder 101. The compression block 104 is made of rubber. A guide groove 105 is provided on the side of the first ladder 1. The guide groove 105 is slidably connected to the guide block 102. A telescopic groove 106 is provided on the other side of the first ladder 1. A telescopic block 107 is telescopically connected inside the telescopic groove 106 by a spring. The telescopic block 107 is engaged with the through-hole 103.

[0022] When the ladder needs maintenance and disassembly, the compression block 104 can be pressed. When the compression block 104 is pressed, it deforms through the rubber material. When the compression block 104 deforms, it can press the side of the telescopic block 107. When the telescopic block 107 is pressed, it can slide inside the telescopic groove 106 and the engaging groove 103. When the telescopic block 107 slides, it can compress the spring. After the telescopic block 107 is pressed into the telescopic groove 106, the second ladder 2 is pulled down. When the second ladder 2 is pulled down, it can drive the fixed cylinder 101 to move down. When the fixed cylinder 101 moves down, it can drive the guide block 102 to move. When the guide block 102 moves, it can slide inside the guide groove 105. When the guide block 102 slides out of the guide groove 105, the fixed cylinder 101 can separate from the first ladder 1, thereby realizing the separation of the second ladder 2 from the first ladder 1. After the second ladder 2 is separated, the ladder can be stored conveniently. At the same time, it is convenient that if the ladder parts are damaged in the future, the whole ladder does not need to be replaced, thus reducing the cost of use.

[0023] Example 2, as follows Figures 1-6 The present invention provides the following technical solution: In order to solve the problem that the connection between the first ladder 1 and the second ladder 2 is unstable and may affect the support effect of the ladder, a flipping mechanism is disclosed based on the first embodiment. A rotating mechanism is provided on the outside of the fixed cylinder 101 to improve the installation stability of the second ladder 2 and the first ladder 1. The rotating mechanism includes two rotating rods 201 that rotate symmetrically on the side of the fixed cylinder 101 through a rotating axis. An external rod 202 is symmetrically fixed on the outside of the first ladder 1, and the end of the external rod 202 is connected to a rubber protective sleeve. A fixing block 203 is fixed at the bottom of the first ladder 1 and the external rod 202. A through hole is provided at the end of the fixing block 203 and the rotating rod 201, and a pin 204 is slidably connected through the two through holes. A telescopic block 205 is slidably connected through the inside of the pin 204, and a spring is connected between the telescopic block 205 and the pin 204.

[0024] When assembling the first ladder 1 and the second ladder 2, the first ladder 1 can be inserted into the fixed cylinder 101. To improve the stability of the connection between the first ladder 1 and the second ladder 2, the rotating rod 201 can be rotated. When the rotating rod 201 rotates, it can rotate on the side of the fixed cylinder 101 via the pivot. When the rotating rod 201 rotates, it can rotate to the inside of the fixed block 203. Slowly rotate the rotating rod 201 so that the through hole of the rotating rod 201 is rotated to the side of the through hole of the fixed block 203. Then press the telescopic block 205 to slide through the pin 204. When the telescopic block 205 slides, it can compress the spring inside the pin 204. After the telescopic block 205 is compressed into the pin 204, the pin 204 is moved to the through hole of the fixed block 203. Insertion is performed from the side. When the pin 204 is inserted, it can slide inside the through hole of the fixed block 203 and the rotating rod 201. When the pin 204 slides out of the through hole with the telescopic block 205, the telescopic block 205 can be reset under the action of the spring. When the telescopic block 205 is reset, it can move to the back of the fixed block 203 for positioning. When the telescopic block 205 is positioned, the pin 204 can position the fixed block 203 and the rotating rod 201. After the rotating rod 201 is positioned with the first ladder 1, the other set of rotating rods 201 should be positioned in the same way at the fixed block 203 position at the bottom of the external rod 202. The positioning of the two rotating rods 201 can greatly improve the stability of the connection between the fixed cylinder 101 and the first ladder 1, and ensure the support strength of the ladder.

[0025] 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.
