Description

Technical Field

[0001] The utility model relates to the technical field of ladder surface pedals, and more specifically, to a ladder surface pedal structure that is convenient to lay. Background Technique

[0002] Components used for vertical transportation between floors in buildings. It is used for traffic connection between floors and when there is a large height difference. In multi-story and high-rise buildings equipped with elevators and escalators as the main vertical transportation means, stairs must also be provided. Although elevators are used as the main vertical transportation tools in high-rise buildings, stairs must still be reserved for escape in case of fire. A staircase consists of a continuous flight of steps (also known as a stair run), a landing (rest platform), and enclosing members, etc. The horizontal projection distance between the lowest and highest steps of the staircase is the stair length, and the total height of the steps is the stair height. The image of a multi-story building engraved on a bronze ware during the Warring States period in China already had a staircase depicted. In Italy during the 15th and 16th centuries, indoor staircases were liberated from traditional enclosed spaces and became decorative architectural components with richly varying forms.

[0003] Currently, when decorating a building, as the most important part of the building, the surface of the staircase will also be decorated during the decoration process. When decorating the staircase, decorative pedals are generally laid with cement, or glue is also used to lay the decorative pedals. However, when the decoration of the staircase surface needs to be changed, or when the decorative pedals are damaged and need to be replaced, when disassembling the decorative pedals, not only do the decorative pedals need to be completely damaged to be removed, but also the cement or glue at the bottom of the decorative pedals needs to be completely cleaned before a new decorative pedal can be replaced. At the same time, when using the above methods to lay decorative pedals, after laying, it is necessary to wait for the cement or glue to dry completely before people can step on them. Whether it is laying or disassembling the decorative pedals, it is relatively troublesome.

[0004] Therefore, in order to solve the above technical problems, this application proposes a ladder surface pedal structure that is convenient to lay. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a ladder surface pedal structure that is convenient to lay.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: including: a staircase arranged in a building;

[0007] The surface of the staircase is detachably installed with a pedal through a quick-release structure, realizing the quick disassembly and assembly between the pedal and the staircase. A limiting structure is arranged in the quick-release structure to limit the installed pedal.

[0008] In this solution, the quick-release structure includes mounting sleeves fixedly installed at the four corners of the stair surface. A bottom cylinder with an interior communicating with the mounting sleeve is provided at the bottom of the mounting sleeve. An insertion cylinder and a limiting rod are detachably inserted into the mounting sleeve and the bottom cylinder. A rotating rod is rotatably installed at the bottom of the insertion cylinder through a bearing with a cavity in the center. The bottom end of the rotating rod penetrates through the cavity in the center of the bearing and is fixedly connected to the top end of the limiting rod inserted into the insertion cylinder, realizing the fixation of the quick-release structure by driving the rotation of the limiting rod through the rotating rod. The insertion cylinder is fixedly installed at the four corners of the installation slots opened in the pedal.

[0009] In this embodiment, the limiting structure includes a rotating groove opened at the top end of the insertion cylinder for rotating the rotating rod, and clamping grooves adapted to it for fixing the rotating position of the rotating rod are opened around the rotating groove. A clamping plate is detachably inserted into the clamping groove. The bottom end of the clamping plate is inserted into the rotating rod and is connected to the inner center inner side wall of the rotating rod through a return spring, realizing the rotation of the rotating rod and limiting the rotation angle of the rotating rod by the position where the clamping groove is opened.

[0010] It should be noted that rotatable convex rings are provided around the bottom end of the rotating rod inserted into the insertion cylinder. One side of a sliding ball slides against the surface of the convex ring and the bottom end of the rotating rod. The other side of the sliding ball is fixedly connected to a positioning rod penetrating through the outer circumference of the insertion cylinder. The other side of the sliding ball is connected to the inner side wall of the insertion cylinder through a compression spring. The end of the positioning rod inserted outside the insertion cylinder is detachably inserted into the positioning hole opened in the inner side wall of the mounting sleeve, realizing the limitation of the insertion cylinder in the mounting sleeve;

[0011] A groove for inserting and positioning the sliding ball is opened at the most protruding position of the convex ring, realizing the fixation of the sliding ball at the most protruding position of the convex ring.

[0012] Furthermore, racks are symmetrically arranged on the surface of the limiting rod. The racks are detachably meshed with the tooth grooves. The tooth grooves are arranged on the inner side wall of the bottom cylinder. When the clamping plate inserted into the rotating rod rotates and switches to different clamping grooves for limiting, at this time, the racks reach meshing with the tooth grooves, realizing the fixation of the positions of the insertion cylinder and the limiting rod in the mounting sleeve and the bottom cylinder.

[0013] Among them, a plug plate at the bottom of a decorative plate is detachably inserted into the installation slot. The plug plate has deformability and is adapted to the size of the installation slot, realizing that inserting the plug plate into the installation slot can fill and squeeze-fix the installation slot, and decorating the surface of the pedal through the decorative plate.

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

[0015] 1. Quick disassembly and assembly: Through the quick-release structure, the quick disassembly and assembly between the pedal and the stairs are realized. There is no need to damage the pedal or remove materials such as cement and glue at the bottom, improving the construction efficiency and reducing the trouble of replacement and maintenance.

[0016] 2. Stable Limiting: A limiting structure is provided inside the quick-release structure to ensure that the pedal is stable and reliable after installation, prevent loosening or detachment during use, and improve the safety of use.

[0017] 3. Convenient Decoration: The pedal is provided with an installation groove, which can facilitate the insertion of the decorative board and the plug board, not only beautifying the appearance of the pedal, but also facilitating the replacement and maintenance of the subsequent decorative board, increasing the aesthetics and personalization of the stairs.

[0018] 4. Strong Adaptability: The tread pedal structure is applicable to various building stairs. Whether it is a newly built staircase or an old building renovation, it can be conveniently installed and replaced, with broad application prospects.

[0019] 5. Reduction of Construction Costs: Since the process of installing and disassembling the pedal is simplified, material waste and labor costs are reduced, thereby reducing the construction cost and improving economic efficiency. Description of the Drawings

Detailed Embodiment

[0027] As Figures 1-5 shown, the present invention provides a tread pedal structure for convenient laying, including: a staircase 6 provided in a building;

[0028] The surface of the staircase 6 is detachably installed with a tread 5 through a quick-release structure, realizing the quick disassembly and assembly between the tread 5 and the staircase 6. A limiting structure is arranged inside the quick-release structure to limit the installed tread 5.

[0029] The quick-release structure includes mounting sleeves 7 fixedly installed at the four corners of the surface of the staircase 6. At the bottom of the mounting sleeve 7, there is a bottom cylinder 14 internally communicating with the mounting sleeve 7. The mounting sleeve 7 and the bottom cylinder 14 are detachably inserted with an insertion cylinder 3 and a limiting rod 10. At the bottom inside the insertion cylinder 3, a rotating rod 8 is rotatably installed through a bearing 21 with a cavity in the center. The bottom end of the rotating rod 8 penetrates through the cavity in the center of the bearing 21 and is fixedly connected to the top end of the limiting rod 10 inserted in the insertion cylinder 3, realizing the fixation of the quick-release structure by driving the rotation of the limiting rod 10 through the rotating rod 8. The insertion cylinder 3 is fixedly installed at the four corners of the mounting groove 4 opened inside the tread 5.

[0030] The limiting structure includes a rotating groove opened at the top end of the insertion cylinder 3 for rotating the rotating rod 8, and at the periphery of the rotating groove, there are mating card slots 17 for fixing the rotating position of the rotating rod 8. A card plate 15 is detachably inserted in the card slot 17. The bottom end of the card plate 15 is inserted into the rotating rod 8 and is connected to the inner center inner side wall of the rotating rod 8 through a return spring 18, realizing the rotation of the rotating rod 8 and limiting the rotation angle of the rotating rod 8 through the position where the card slot 17 is opened.

[0031] Around the bottom end of the rotating rod 8 inserted in the insertion cylinder 3, there is a rotatable convex ring 20. One side of the convex ring 20 slides in contact with one side of a sliding ball 22, and the other side of the sliding ball 22 is fixedly connected to a positioning rod 9 penetrating through the outer periphery of the insertion cylinder 3. Moreover, the other side of the sliding ball 22 is connected to the inner side wall of the insertion cylinder 3 through a compression spring 23. The positioning rod 9 inserted at one end outside the insertion cylinder 3 is detachably inserted in the positioning hole 12 opened on the inner side wall of the mounting sleeve 7, realizing the limitation of the insertion cylinder 3 in the mounting sleeve 7.

[0032] A groove 19 for inserting and positioning the sliding ball 22 is opened at the most protruding position of the convex ring 20, realizing the fixation of the sliding ball 22 at the most protruding position of the convex ring 20.

[0033] Rack teeth 11 are symmetrically arranged on the surface of the limiting rod 10. The rack teeth 11 are detachably meshed and connected in the tooth grooves 13. The tooth grooves 13 are arranged on the inner side wall of the bottom cylinder 14. When the card plate 15 inserted in the rotating rod 8 rotates to switch to different card slots 17 for limiting, at this time, the rack teeth 11 achieve meshing with the tooth grooves 13, realizing the fixation of the positions of the insertion cylinder 3 and the limiting rod 10 in the mounting sleeve 7 and the bottom cylinder 14.

[0034] A plug plate 2 provided at the bottom of the decorative plate 1 is detachably inserted into the installation groove 4. The plug plate 2 has the ability to deform and is adapted to the size of the installation groove 4, so that when the plug plate 2 is inserted into the installation groove 4, the installation groove 4 can be filled and squeezed and fixed, and the surface of the pedal 5 is decorated by the decorative plate 1.

[0035] Working principle: During use, when installing the decorative pedal 5, after drilling holes at the four corners of the surface of the staircase 6 at appropriate positions, an integral installation sleeve 7 and a bottom cylinder 14 are inserted into the drilled holes and fixed. After taking out the pedal 5, the insertion cylinders 3 and the limiting rods 10 provided at the four corners of the bottom of the pedal 5 are inserted into the installation sleeve 7. After pressing the pedal 5 downward to fit with the surface of the staircase 6, the pedal 5 is fixed at this time;

[0036] Press the clamping plates 15 provided around the rotating rod 8 inward. The clamping plates 15 contract into the rotating rod 8 and squeeze the return spring 18. Thus, after the clamping plates 15 are contracted from a set of clamping grooves 17, the rotating rod 8 is rotated. The rotating rod 8 rotates under the action of the bearing 21. During the rotation of the rotating rod 8, the convex ring 20 provided on the outer side of the bottom end is driven to rotate. The surface of the bottom end of the rotating rod 8 and the surface of the convex ring 20 are in contact and slide. At this time, when the convex ring 20 provided around the bottom end of the rotating rod 8 touches the sliding ball 22, the convex ring 20 protrudes outward due to its own size. Therefore, the positioning rod 9 will be pushed out of the insertion cylinder 3 through the sliding ball 22. At this time, the sliding ball 22 will squeeze the compression spring 23. When the sliding ball 22 rotates to the most protruding position of the convex ring 20 and is inserted into the groove 19 to limit the position of the sliding ball 22. At this time, during the process of the positioning rod 9 being pushed outwards, the positioning rod 9 is inserted into the positioning holes 12 opened on the inner side wall of the installation sleeve 7, thereby fixing and limiting between the insertion cylinder 3 and the installation sleeve 7. At the same time, during the rotation of the rotating rod 8, the rack 11 provided on the outer side of the limiting rod 10 will be engaged with the tooth groove 13, thereby restricting and fixing the positions of the insertion cylinder 3 and the limiting rod 10 in the installation sleeve 7 and the bottom cylinder 14;

[0037] After limiting between the insertion cylinder 3 and the installation sleeve 7, at this time, the clamping plate 15 is inserted into the clamping groove 17, and the rotating rod 8 is limited by the rebound of the return spring 18, realizing the fixation between the pedal 5 and the staircase 6;

[0038] After installing between the pedal 5 and the staircase 6, take out the decorative plate 1 for decoration and insert the plug plate 2 into the installation groove 4 opened on the surface of the pedal 5. The decorative plate 1 is fixed by the extrusion between the plug plate 2 and the installation groove 4 due to the size, thereby fixing between the decorative plate 1, the pedal 5 and the staircase 6;

[0039] When it is necessary to disassemble the pedal 5, first use a crowbar or other device to pull out the decorative plate 1 from the installation groove 4 opened in the pedal 5. After the installation groove 4 is exposed, squeeze the clamping plate 15 inward and then reverse-rotate the rotating rod 8, and then the convex ring 20 at the bottom end of the rotating rod 8 can be separated from the sliding ball 22. Under the rebound action of the compression spring 23, the positioning rod 9 is contracted inward, so that the positioning rod 9 is contracted from the positioning hole 12 into the insertion cylinder 3. At the same time, the insertion strip and the insertion slot are also separated, and the limiting between the insertion cylinder 3 and the limiting rod 10 and the installation sleeve 7 and the bottom cylinder 14 can be separated. At this time, the insertion cylinder 3 can be pulled out from the installation sleeve 7, and then the pedal 5 can be disassembled.

[0040] The above is only the preferred embodiment of the present invention, and it is not intended to limit the present invention in any form; any ordinary technician in the industry can smoothly implement the present invention as shown in the accompanying drawings of the specification and the above description; however, any minor changes, modifications and equivalent changes made by those familiar with the professional technology without departing from the technical solution of the present invention, using the technical content disclosed above, are all equivalent embodiments of the present invention; at the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essence of the present invention still fall within the protection scope of the technical solution of the present invention.
