Description

Technical Field

[0001] This invention provides a trolley and its method of use, and particularly relates to a toilet installation trolley and its method of use. Background Technology

[0002] During bathroom installation, toilet installation requires specialized tools for handling and positioning. Common toilet installation tools on the market fall into two main categories: one is a "homemade rope with a tilting trolley," consisting of a simple tilting trolley and ordinary ropes. The toilet is secured to the trolley with the ropes, and the toilet is manually tilted and adjusted before being moved and installed. Its advantages are simple structure and low cost. The other category is "manual tilting and handling with a drain outlet positioning mechanism," which only includes a simple drain outlet positioning reference and lacks a dedicated handling support structure. The toilet must be manually tilted and moved, and the positioning reference is used to initially align it with the drain outlet on the ground. Its advantage is that the positioning mechanism provides a rough reference for the drain outlet. However, both types of existing tools have significant shortcomings: First, the drain hole positioning is inaccurate. Whether using a trolley secured by ropes or manual tilting with a positioning mechanism, the ropes provide poor stability and the positioning reference parts have low precision. As the toilet tilts or falls to the ground, positional deviations are easily observed, leading to misalignment of the drain hole or bolt holes. Second, there is a lack of flange bolt positioning mechanisms. Existing tools do not have positioning components for European and American toilets with flange bolts. When installing such toilets, it is impossible to guide the bolt holes and flange bolts to align precisely, resulting in difficulties in hole alignment and inaccurate installation positions, affecting installation efficiency and quality. Finally, their applicability is limited. Existing tools are mainly designed for domestic toilets without locking bolts and have poor compatibility with European and American toilets with flange bolts. They cannot meet the installation needs of different types of toilets. Furthermore, neither type of tool has a labor-saving lifting and stable handling structure, requiring multiple people to work together or laborious tilting and handling, resulting in high labor intensity and making independent installation by a single person impossible. Summary of the Invention

[0003] This invention aims to solve the problems of inaccurate positioning of drain holes, lack of anchor bolt positioning mechanism, limited applicability, and laborious operation of existing toilet installation tools. It provides a toilet installation trolley that enables labor-saving lifting and stable transportation, ensuring that the toilet can be installed without tilting or flipping, accurately aligning the drain hole or bolt hole, adapting to different types of toilets at home and abroad, and allowing a single person to complete the installation independently.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a toilet installation trolley, comprising a frame, casters, a lever mechanism, an adjustable binding rope, a positioning marker plate, a bolt positioning guide sleeve for a bolt wrench, and matching fastening components; the frame consists of a left frame, a right frame, and frame crossbars, made of high-strength steel, possessing sufficient load-bearing capacity and stability to provide overall support; four casters are installed at the bottom of the frame, and each caster is equipped with a brake assembly to allow for flexible movement of the frame on different terrains, and can be locked during installation. Fixed casters prevent frame displacement. The lever mechanism, mounted on the frame, includes a lever handle, a handle bar, a fulcrum pin, V-shaped ball bearings, a pin, and an anti-slip pad. The fulcrum pin serves as the rotation fulcrum of the lever mechanism. The V-shaped ball bearings are embedded in the connection between the lever mechanism and the frame. The anti-slip pad is located at the contact end of the lever mechanism. The handle bar is fixed to the lever handle. When the operator grips the handle bar and applies force, the toilet is lifted at the contact end using the lever principle, with the fulcrum pin as the center. The V-shaped ball bearings can be inserted into corresponding positioning slots for temporary positioning. The pin is inserted into the lever mechanism. The positioning holes of the mechanism are used to fix the height of the toilet and keep it level; the adjustable binding rope is a high-strength wear-resistant rope with an adjustable length (adjustment range of 500mm-1200mm), one end of which is detachably connected to the fixed end of the lever mechanism, and the other end is equipped with a hook or strap made of anti-slip material for binding the rear end of the toilet; the positioning mark plate is mounted on the frame to assist in aligning the toilet drain hole with the ground drain outlet or the toilet bolt hole with the anchor bolt; the bolt positioning guide sleeve of the bolt wrench is a hollow structure made of stainless steel, used to pass through the toilet bolt hole and fit on the... Outside the anchor bolts, guide the precise alignment of the two components; the matching fastening components include a bolt wrench, a Φ8 flat washer and an M8 nut that come with the trolley, and a 1 / 4 nut and a 1 / 4 nut flat washer used when installing the toilet; the bolt wrench is used to tighten the anchor bolts; the Φ8 flat washer and the M8 nut are parts that come with the trolley and are used to work with the fulcrum pin to lock the lever mechanism to the frame; the 1 / 4 nut and the 1 / 4 nut flat washer are parts used during the installation process to tighten onto the anchor bolts to lock the toilet to the ground / flange.

[0005] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages compared with the prior art:

[0006] 1. Labor-saving and efficient: Utilizing the lever principle through a lever mechanism, operators can easily lift the toilet by simply holding the handle and applying force, significantly reducing labor intensity. Furthermore, the casters facilitate flexible transportation and improve installation efficiency.

[0007] 2. Precise positioning: The positioning mark plate assists in the initial calibration of the position, and the bolt positioning guide sleeve of the bolt wrench ensures that the bolt holes of the European and American flanged screw toilets are accurately aligned, avoiding positional deviations caused by flipping or tilting, resulting in higher positioning accuracy;

[0008] 3. Wide range of applications: It can be used to install domestic toilets without locking bolts by aligning the drain hole with the positioning mark plate, and it can also be used to install European and American toilets with flange bolts by using the bolt positioning guide sleeve part of the bolt wrench and the matching fastening components. It has strong compatibility.

[0009] 4. Easy to operate: The overall structure is simple, and the adjustable rope allows for quick fixing and disassembly of the toilet. The caster brake assembly ensures stable installation. Especially when using an aluminum alloy frame, a single person can complete the entire installation process independently.

[0010] Other advantages, objectives and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be learned from the practice of the invention.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] like Figure 1-4As shown, the left frame 1 and right frame 2 of the trolley are symmetrically and parallelly arranged, and are fixedly connected by at least two frame crossbars 4 (the left and right frames and crossbars are connected by a round tube snap-fit ​​quick-connect structure, and quick disassembly and assembly are achieved by the elastic limit of V-shaped ball springs 11), together forming the main support body of the frame; four casters 10 are detachably installed at the four corners of the bottom of the frame by bolts (the mounting seat of each caster 10 is fixedly connected to the bottom end of the left frame 1 and the right frame 2 of the trolley), and the axle is parallel to the bottom surface of the frame; the middle of the lever mechanism is connected by... The pivot pin 12 is rotatably connected to the frame crossbar 4 near the front end of the frame (the pivot pin 12 passes laterally through the connecting lug plate between the frame crossbar 4 and the lever mechanism, allowing the lever mechanism to rotate about the pivot pin 12 as an axis); the V-shaped ball spring 11 is embedded in the inner wall of the connecting lug plate of the lever mechanism, corresponding to several pre-set positioning slots on the frame crossbar 4 of the frame (the positioning slots are adapted to the protrusions of the V-shaped ball spring 11, and the lifting limit is limited by the limiting post of the frame itself); the handle crossbar 5 is laterally welded to the rear end of the lever mechanism and vertically integrated with the lever push handle 3 (the lever push handle 3 consists of two bars). A parallel rod body, with a handle bar 5 at the top and extending to the toilet contact end at the bottom; an anti-slip pad is pasted on the front contact end of the lever mechanism, with an anti-slip texture on the surface; a pin 9 is installed at the bottom of the lever handle 3 of the lever mechanism through a sleeve, corresponding to the gap hole on the lever handle 3 (the pin is inserted into the gap to maintain the height of the toilet); one end of an adjustable rope 8 is detachably connected to one end of the lever handle 3 in the lever mechanism, and the other end is hooked / tied around the rear end of the toilet and connected to one end of the lever handle 3 on the other side to fix the toilet and the trolley lever mechanism; positioning mark. Plate 7 is used to assist in aligning the toilet drain hole with the floor drain outlet or the toilet bolt hole with the anchor bolt. The bolt positioning guide sleeve of the bolt wrench is an independent component. When in use, it is inserted through the toilet bolt hole and placed on the top of the anchor bolt to guide the two to be accurately aligned. The matching fastening components (bolt wrench 6, Φ8 flat washer 13 and M8 nut 14 that come with the trolley, 1 / 4 nut and 1 / 4 nut flat washer used when installing the toilet) can be placed in the storage bag on the side of the frame.

[0021] In this implementation plan, all components work collaboratively around the frame: the lever mechanism achieves rotatable connection based on the fulcrum pin 12; the V-shaped ball spring 11 cooperates with the positioning groove to complete the temporary positioning during the lifting process (the lifting limit is limited by the frame's own limiting post); the pin 9 is inserted into the pin hole to lock the height, ensuring that the toilet is always level; the casters 10 enable flexible transportation, and the brake assembly locks the installation position; the adjustable binding rope 8 adapts to different sizes of toilets and provides stable fixation; the positioning mark plate 7 provides a preliminary alignment benchmark; the bolt positioning guide sleeve of the bolt wrench accurately guides the anchor bolts to be aligned; and the matching fastening assembly completes the final fixation of the toilet with anchor bolts, forming a complete process of "fixing-lifting-transporting-positioning-installation", which can be completed without flipping the toilet.

[0022] Specifically, the frame (left frame 1, right frame 2, and crossbar 4) adopts a round tube snap-fit ​​quick-connect structure, which uses V-shaped ball springs 11 for elastic limiting to achieve quick assembly and disassembly. At the same time, it solves the problems of weak support and easy deformation of existing tools. The integrated frame provides sufficient load-bearing capacity (suitable for the weight of common toilets). The symmetrical structure ensures that the toilet is evenly stressed, avoids tilting during transportation, and provides a stable installation base for all functional components, ensuring the overall structural synergy.

[0023] Casters 10: Solve the problems of laborious handling and inconvenient steering of existing tools. The omnidirectional design allows the trolley to turn flexibly in narrow bathroom spaces (without moving the whole thing). The brake assembly locks in position during installation to prevent positioning deviation caused by frame displacement and reduce the intensity of manual handling.

[0024] Lever mechanism (fulcrum pin 12, V-shaped ball spring 11, handle bar 5, pin 9, anti-slip pad): solves the problems of difficult lifting and uncontrollable height of existing tools. The lever principle amplifies the manual force (one person can lift the toilet by holding the handle bar). The temporary positioning of the V-shaped ball spring prevents the lever from falling back during lifting. The lifting limit is guaranteed by the frame's own limit post. The pin lock ensures that the toilet is level (preventing hole displacement caused by flipping). The anti-slip pad prevents the toilet from sliding and further improves the positioning accuracy.

[0025] Adjustable tie rope 8: Solves the problems of existing tie ropes being not secure and having poor adaptability. The length is adjustable (adjustment range is 500mm-1200mm) to fit different sizes of toilets (from ordinary household toilets to large smart toilets). The detachable connection makes it easy to install and remove. The anti-slip hooks / tips ensure that the toilet does not loosen during transportation and avoid positional deviation caused by the tie rope slipping.

[0026] Positioning Marker 7: Solves the problem of existing tools lacking a precise alignment benchmark. The marking line coincides with the center line of the frame. Operators can use the marking plate to quickly calibrate the relative position of the toilet and the ground drain outlet / anchor bolt, reducing repeated adjustment time and improving positioning efficiency.

[0027] Bolt positioning guide sleeve part of the bolt wrench: solves the problem of difficulty in aligning the holes of toilets with anchor bolts in Europe and America. The hollow structure guides the accurate insertion of the anchor bolt into the toilet bolt hole, avoiding deviations caused by manual alignment (especially when the bolt hole is hidden), ensuring accurate installation position, and improving the installation quality of toilets with anchor bolts.

[0028] Matching fastening components (bolt wrench 6, Φ8 flat washer 13 and M8 nut 14 included with the trolley, 1 / 4 nut and 1 / 4 nut flat washer used for toilet installation): The Φ8 flat washer 13 and M8 nut 14 are included with the trolley and are used to lock the lever mechanism to the frame in conjunction with the fulcrum pin 12; the 1 / 4 nut and 1 / 4 nut flat washer are used during installation to tighten onto the anchor bolts to lock the toilet to the ground / flange. This component solves the problem of needing to carry additional fastening parts with existing tools. The dedicated bolt wrench 6 is compatible with the anchor bolt specifications, ensuring the toilet is firmly fixed and preventing leakage or displacement caused by loosening after installation. It improves the installation process of toilets with anchor bolts without the need for additional tools.

[0029] This device requires the use of conventional devices or tools based on existing technology to complete the toilet installation process, ensuring a closed-loop installation workflow. While these existing devices are not explicitly labeled in the diagrams within this device structure, they are indispensable auxiliary components during installation. Specifically, they include the following categories:

[0030] Floor cleaning tools, such as brooms and rags, are used to clean dust, sand, and debris from the floor in the installation area before toilet installation. This prevents debris from affecting the fit between the toilet base and the floor, and prevents leaks or tilting of the toilet after installation. These tools are standard pre-treatment tools in bathroom installation scenarios and belong to existing mature technology.

[0031] Horizontal measuring tools, such as bar levels or laser levels, are used to check whether the toilet is level after it has been lowered vertically to the ground. This helps operators fine-tune the toilet's position to ensure that there are no height differences after installation, thus avoiding poor drainage or discomfort caused by minor unevenness in the ground. This tool is a commonly used leveling device in the construction and decoration industry, with mature technology and wide application.

[0032] Sealing tools, such as caulking guns and neutral silicone sealant, are used in the later stages of toilet installation in China where there are no locking bolts. They are applied to seal the gap between the toilet bottom and the ground to enhance the seal between the toilet and the ground and prevent sewage leakage. Caulking guns are existing specialized tools for applying silicone sealant, while neutral silicone sealant is a commonly used sealing material in bathroom settings. Both are existing conventional bathroom installation consumables and tools.

[0033] Dimensional measuring tools, such as steel tape measures, are used to measure the length, width, and other dimensions of the toilet before it is fixed in place. This helps operators adjust the length of the adjustable straps (ensuring an adjustment range of 500mm-1200mm) to ensure that the adjustable straps can be accurately secured to the back of the toilet. It can also measure the spatial dimensions of the installation location to confirm that the trolley and toilet can smoothly enter the installation area. This tool is a basic tool in the field of daily measurement and falls within the scope of existing technology.

[0034] Surface protection tools, such as pearl cotton pads or soft cloths, are used to place the toilet on the trolley frame before it is placed on the trolley frame at the contact point between the trolley frame and the bottom of the toilet. This prevents the glaze on the bottom of the toilet from being scratched or damaged by the trolley frame or anti-slip mat, thus protecting the integrity of the toilet's appearance. Such protective materials are commonly used protective measures during the transportation and installation of existing products, and the technology is mature and readily available.

[0035] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Anyone skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
