Description

Technical Field

[0001] This utility model relates to the field of work platform technology, and more specifically, to a foldable, flat, height-adjustable car wash platform with independently adjustable height support legs. Background Technology

[0002] Car wash benches or multi-functional work platforms are widely used auxiliary tools for vehicle washing and detailing, building renovation, home repairs, or other work at height. Examples of such products currently on the market are shown in the attached image. Figure 1 and Figure 2 The existing technologies shown generally have a common defect in their structural design: after being folded and stored, their support leg structures still have a large thickness or height due to structural limitations.

[0003] This non-flattened storage design directly results in bulky product packaging, causing inconvenience for users in storage and carrying, and significantly increasing warehousing, logistics, and commercial transportation costs. To address this issue, CN206376734U discloses a hand-carrying car wash platform. However, although this platform retracts its side ladders to the sides of the platform, the ladders are limited by the platform's length, severely restricting the overall working height of the platform and making it unsuitable for uneven surfaces, greatly limiting its practical application scenarios.

The height telescopic locking assembly has a locking position that can be operably limited to the position of the lower inner leg and an unlocking position that allows the lower inner leg to telescopically move.

[0011] As one aspect of this application, the side wall of the lower inner leg is provided with a plurality of locking holes arranged along its length. The height telescopic locking assembly includes a locking seat, a second locking rod movably disposed on the locking seat, and a second spring sleeved on the second locking rod; the second locking rod passes through the upper end of the support leg; a second blocking part is also fixed on the second locking rod; the second spring is located inside the locking seat and is compressed and limited between the second blocking part and the top wall of the locking seat; the insertion end of the second locking rod can be selectively inserted into different locking holes to adjust the support leg to different extension amounts; the other end of the second locking rod is located outside the locking seat and is provided with a force-receiving part that accepts force applied by the user.

Detailed Implementation

[0025] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0026] Please see Figures 3 to 13 One embodiment of this utility model provides a flat, adjustable-height car wash bench. For example... Figure 3As shown, in its working state, the car wash platform mainly comprises a horizontal support platform 100 and two support mechanisms symmetrically arranged at both ends of the support platform 100. The support mechanisms are rotatably connected to the ends of the support platform 100 via rotating connecting parts 40. Each support mechanism consists of two support legs 10 and multiple footrails 5 fixed between them by connecting stiffeners 15, forming a stable support structure that can be climbed. In the flattened state, the two support mechanisms remain flush with the ends of the support legs 10 facing each other, parallel to each other on both sides of the support platform 100.

[0027] The support platform 100 has a frame consisting of two parallel long frame walls 101 and two parallel short frame walls 102, and a support plate for standing or placing items is fixed on the frame. The support mechanism can rotate about the rotating connection 40, allowing the car wash platform to operate in a working state (e.g., ...). Figure 3 (as shown) and flat state (as shown) Figure 4 and Figure 5 Switching between (as shown). Specifically, the rotating connection part 40 can be a connecting bushing, which penetrates the side walls with shaft holes on both sides and is installed and tamper-proof by punching and riveting at the ends.

[0028] In the flat state, the two support legs 10 of the support mechanism are located parallel to the support platform 100 on both sides of the platform 100, with each support leg 10 at its shortest length. This ensures that the two support mechanisms in the flat state do not interfere with each other and can be positioned at the same height on both sides of the support platform 100, reducing the height of the car wash platform in the flat state. In the working state, the support mechanism supports the support platform 100 at an obtuse angle with it, allowing the length of the support legs 10 to be adjusted.

[0029] To achieve stable locking in both states, the car wash platform is equipped with a retractable card assembly 20 at the upper end of the support leg 10. For example... Figures 6 to 9 As shown, the retractable card assembly 20 can lock the support mechanism at a specific angular position. The retractable card assembly 20 has a locking position for operably locking the support mechanism and a releasing position for allowing the support mechanism to rotate. Each support mechanism may have one retractable card assembly 20.

[0030] Specifically, the end of the long frame wall 101 is provided with two positioning holes: a first positioning hole 105 and a second positioning hole 106. The first positioning hole 105 is used to lock the working state, and the second positioning hole 106 is used to lock the flat state. In a preferred embodiment, as... Figure 8As shown, the first positioning hole 105 is closer to the outer end of the support platform than the second positioning hole 106, and the position of the second positioning hole 106 is higher than that of the first positioning hole 105. This layout conforms to the natural rotation trajectory of the support legs in both states and can position the support mechanism in the desired working state position and flat state position. In particular, the position of the second positioning hole 106 can position the two support legs 10 in the desired position to minimize the storage height and thickness of the car wash platform in the flat state.

[0031] like Figure 7 and Figure 9 As shown, the telescopic card assembly 20 includes a first locking rod 24, the insertion end 26 of which can be selectively inserted into a first positioning hole 105 or a second positioning hole 106. A first spring 23 is sleeved on the first locking rod 24, and an operating part 22 for receiving user pressure is provided. The operating part 22 can be a force-applying knob or a button-like structure, which is not limited in this embodiment. The first spring 23 is located inside the support leg 10 (upper leg frame 11) and is compressed and limited between the first blocking part and the outer wall of the support leg; the insertion end of the first locking rod 24 can be selectively inserted into the first positioning hole 105 or the second positioning hole 106 to be in different locking positions, realizing the switching positioning of the car wash platform in working state and flat state. The first blocking part 25 can be a blocking ring or a blocking rod fixed on the first locking rod 24.

[0032] Under the elastic force of the first spring 23, the first locking lever 24 is in the default extended and locked position, which is the initial position of the first locking lever 24. To ensure that the first locking lever 24 moves smoothly and does not rotate, a guide sleeve 21 can be fitted on its exterior. The guide sleeve 21 has an anti-rotation surface 211 that fits against the inner wall of the support leg 10. Of course, the guide sleeve 21 can also be fixedly connected to the support leg 10 by means such as welding.

[0033] When the car wash platform is switched to working mode, the user unfolds the support mechanism outward. When the tread surface 61 of the uppermost step 6 contacts the lower positioning part 103 protruding downward at the end of the support platform 100, a physical limit is formed, and the support mechanism reaches the preset working angle. The insertion end 26 of the first locking rod 24 is precisely aligned with the first positioning hole 105 and automatically inserted under the elastic force of the first spring 23, making a "click" sound, thus locking the working state and ensuring safe use.

[0034] When the car wash platform is switched to the flat position, the user squeezes the operating part 22 and pulls it outward, causing the first locking lever 24 to retract from the first positioning hole 105 to the release position, and then rotates the support mechanism inward. When the inner side wall 53 of the support leg 10 and the step bar 5 contacts and is limited by the long frame wall 101, the support mechanism reaches the flat position, at which point it is parallel to the table surface of the support platform 100. The insertion end 26 of the first locking lever 24 is aligned with the second positioning hole 106 and inserted into the locking position, completing the locking of the flat position. In this state, the total length of the two support mechanisms is less than or equal to the length of the support platform 100, and at this time the outer side wall 52 of the step bar is parallel to the table surface of the support platform, allowing it to be set horizontally when placed, which not only facilitates the overall stability when placed on the ground, but also achieves ultimate flat storage.

[0035] In this embodiment, the height of the support leg 10 can be adjusted independently, not only to cooperate with the support platform 20 in a flat state for parallel positioning, but also to adapt to uneven working environments. Figure 10 As shown, each support leg 10 is a telescopic sleeve structure, including an upper leg frame 11 and a lower inner leg 12 slidably fitted therein. The lower end of the lower inner leg 12 is provided with a support foot shell. To lock the extended position of the lower inner leg 12, a height telescopic locking assembly 30 is provided at the lower end of the upper leg frame 11.

[0036] like Figures 11 to 13 As shown, each support leg 10 is equipped with a height telescopic locking assembly 30. Each lower inner leg 12 has a series of locking holes 121 evenly arranged along its length on its side wall. The height telescopic locking assembly 30 has a locking position that operably limits the position of the lower inner leg 12 and an unlocking position that allows the lower inner leg 12 to telescopically move.

[0037] The structure of the telescopic card assembly 30 is similar to that of the telescopic card storage assembly 20, including a second locking rod 34 installed in the card holder 31, a second spring 33, and a force-receiving part 32 for user operation. The card holder 31 has a through hole 311 through which the second locking rod 34 passes. The card holder 31 is fixedly installed on the front side wall of the lower end of the upper leg frame 11. The force-receiving part 32 can be a force-applying knob or a button-like structure; this embodiment is not limited to this. The second spring 33 is located inside the card holder 31 and is compressed and confined between the second blocking part 35 and the top wall of the card holder 31.

[0038] The insertion end 36 of the second locking lever 34 is inserted into one of the locking holes 121 under the action of spring force, thereby locking the lower inner leg 12 reliably relative to the upper leg frame 11. By pulling the force-receiving part 32, the second locking lever can be pulled out to switch to the unlocked position, and the extension length of the lower inner leg 12 can be freely adjusted to adapt to different heights or uneven ground.

[0039] To facilitate leg extension, a guide slope 361 is preferably provided on the upper side of the insertion end 36 of the second locking rod 34. The guide slope 361 gradually slopes downward toward the end face of the insertion end 36 of the second locking rod. The guide slope 361 faces upward. When the second locking rod 34 is in the locked position, the inner wall of the locking hole 121 is located on the periphery of the guide slope 361, and the guide slope 361 and the inner wall of the locking hole 121 are directly opposite each other in the radial direction. When the lower inner leg 12 is pulled downward, the hole wall of the locking hole 121 will push the second locking rod 34 back along the guide slope 361, and the step-by-step extension operation can be completed without pulling the force-bearing part 32. When retracting, the force-bearing part 32 can be pulled. This design can take into account both the convenience of operation and the safety of use.

[0040] In summary, this utility model, through its ingenious rotating locking mechanism and independent telescopic leg adjustment mechanism, successfully achieves the flattened storage of the car wash platform while ensuring functionality and safety, demonstrating significant practical value and market advantages.
