Description

Technical Field

[0001] This utility model relates to the field of transportation technology, and in particular to a walk-in bathtub transport bracket. Background Technology

[0002] As living standards improve, more and more people are installing bathtubs in their bathrooms to relax and unwind. However, getting into a bathtub can be difficult for older people. To address this, bathtubs designed for elderly users have been developed. These bathtubs feature an entrance on the side wall with a revolving door to close the entrance and create a soaking space. During the production of these walk-in bathtubs, a layer of fiberglass is typically sprayed onto the outer bottom. After the fiberglass coating is completed, the bathtub is inverted and transported to another workshop for further processing. Currently, the bathtubs are usually transported by hoisting them onto a trolley. This method usually requires multiple workers to assist in positioning and installing the walk-in bathtub so that it can be stably placed on the trolley, and then the trolley is pulled to complete the transfer.

[0003] However, since typical trolleys are flat-panel structures, when hoisting a walk-in bathtub onto the trolley, multiple workers are needed to assist in supporting and restricting the installation process. Simultaneously, it's crucial to prevent swaying during transport. This not only results in high labor intensity for workers but also poses certain dangers. Furthermore, when using trolleys for transport, uneven surfaces can easily cause the bathtub to bounce, and existing trolleys lack the necessary restraints and fixations, making them highly susceptible to bumps and knocks during transport. This can damage the walk-in bathtub, increase waste rates, and reduce transport efficiency. Utility Model Content

[0004] To address the technical deficiencies mentioned in the background section, the present invention aims to provide a walk-in bathtub transport bracket, which solves the problems of existing walk-in bathtubs being difficult to position during transport and prone to shaking, bumping, and collisions. By setting up a lifting mechanism, a supporting mechanism, and a limiting mechanism on the transport bracket, the walk-in bathtub can be fixed in all directions, saving labor transportation costs and effectively improving transportation efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A walk-in bathtub transport bracket includes a base frame for placing the walk-in bathtub and a support frame for restricting the position of the walk-in bathtub on both sides. The support frame is vertically fixed to both sides of the base frame, and the bottom end of the support frame is welded to the base frame. The support frame is characterized by having a lifting mechanism for adjusting the lifting position of the walk-in bathtub, a supporting mechanism for supporting the walk-in bathtub connected to the lifting mechanism, and a limiting mechanism on the side of the support frame near the base frame. The limiting mechanism is located along the four corners of the base frame. When the supporting mechanism carries the walk-in bathtub down the lifting mechanism to be flush with the base frame, the limiting mechanism, under the weight of the walk-in bathtub, completes the limiting and fixing of its front and rear sides.

[0007] Preferably, the limiting mechanism includes a rotating shaft connected between the support frames and a limiting plate sleeved on the rotating shaft. The rotating shaft is located above the bottom frame and is rotatably connected between the support frames along the length of the bottom frame. Multiple limiting plates are provided, and the multiple limiting plates have a V-shaped structure. One side of the limiting plate is inclined towards the outer wall of the walk-in bathtub, and the other side is inclined towards the inner wall of the walk-in bathtub.

[0008] Preferably, the supporting mechanism includes a supporting bracket and a supporting plate. The supporting bracket has a right-angled triangular structure and is movably connected to the lifting mechanism. The supporting plate is arranged laterally along the width direction of the base frame, and the length of the supporting plate is less than the width of the base frame. The supporting plate is fixedly connected to the supporting bracket.

[0009] Preferably, the lifting mechanism includes a lifting slide, a guide rail, a slider, a guide plate, and a drive assembly. The lifting slide is vertically disposed within the support frame, and one side of the lifting slide is fixedly connected to the guide rail. The guide rail is symmetrically disposed on the lifting slide and protrudes from the side wall of the support frame. The slider is slidably connected to the guide rail, and one side of the slider is fixedly connected to the guide plate. One side of the guide plate is drively connected to the drive assembly to drive the guide plate to slide up and down along the guide rail.

[0010] Preferably, the drive assembly includes a rotating handwheel, a drive shaft, and a locking device. The rotating handwheel is fixed to the top of the guide slide and is rotatably connected to the drive shaft. The drive shaft is disposed between the guide slides and a nut seat is sleeved on the drive shaft. One side of the nut seat is fixedly connected to the guide plate. The locking device is disposed at the connection between the rotating handwheel and the drive shaft and is used to lock the lifting position of the walk-in bathtub.

[0011] Preferably, a push-pull plate is fixedly connected to the top of the support frame, and the push-pull plate has push-pull holes adapted for hand gripping.

[0012] Preferably, the four corners at the bottom of the support frame are also provided with swivel casters for assisting movement, and the swivel casters are equipped with brake pads.

[0013] Preferably, the bottom frame includes crossbeams arranged parallel to the support frame and multiple load-bearing bars connected between the crossbeams. The crossbeams and load-bearing bars are hollow aluminum frame structures, and the distance between the load-bearing bars and the support frame is greater than the width of the support mechanism.

[0014] In summary, the beneficial effects of this utility model are as follows:

[0015] This utility model incorporates a lifting mechanism on the support frame, allowing the height of the supporting structure to be adjusted according to loading requirements. This facilitates the loading and unloading of walk-in bathtubs and adapts to different sizes and types of walk-in bathtubs, thus expanding the applicability of the transport support. Furthermore, by connecting limiting mechanisms between the support frames, the walk-in bathtub is fixed in place in all directions, solving the problem of swaying and shifting during transport. This effectively prevents damage from collisions, significantly reduces labor costs, saves time and effort, and improves production efficiency. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-5 The present invention provides a more detailed description of an embodiment of a walk-in bathtub transport bracket.

[0027] A walk-in bathtub transport bracket, such as Figure 1 , 2 As shown, the bathtub 8 includes a base frame 1 for placing the bathtub 8 and a support frame 2 for limiting the position of the bathtub 8 on the left and right sides. The support frame 2 is vertically fixed to both sides of the base frame 1, and the bottom end of the support frame 2 is welded to the base frame 1. The support frame 2 is provided with a lifting mechanism 3 for adjusting the lifting position of the bathtub 8. The lifting mechanism 3 is connected to a support mechanism 4 for supporting the bathtub 8. The support frame 2 is also provided with a limiting mechanism 5 on the side near the base frame 1. The limiting mechanism 5 is provided along the four corners of the base frame 1. When the support mechanism 4 supports the bathtub 8 and slides down the lifting mechanism 3 to be flush with the base frame 1, the limiting mechanism 5 completes the limiting and fixing of the bathtub 8 on its front and rear sides under its own weight.

[0028] Specifically, when loading the walk-in bathtub 8, the transport bracket first slides the supporting mechanism 4 up to the highest position along the lifting mechanism 3. Then, the walk-in bathtub 8 is hoisted onto the transport bracket by a crane and slowly placed on the supporting mechanism 4. After carrying the walk-in bathtub 8, the supporting mechanism 4 slides down along the lifting mechanism 3 onto the bottom frame 1. When the walk-in bathtub 8 contacts the bottom frame 1, the limiting mechanism 5 is pressed down, so that the limiting mechanism 5 can restrict and fix the position of the walk-in bathtub 8. At the same time, under the limiting action of the side support frames 2, it is stably installed on the bottom frame 1, thereby avoiding shaking during transportation and preventing the walk-in bathtub 8 from being bumped. This greatly improves the transfer efficiency of the walk-in bathtub 8.

[0029] In this embodiment, as Figure 2 As shown, the limiting mechanism 5 includes a rotating shaft 51 connected between the support frames 2 and a limiting plate 52 sleeved on the rotating shaft 51. The rotating shaft 51 is located above the bottom frame 1 and is rotatably connected between the support frames 2 along the length of the bottom frame 1. Multiple limiting plates 52 are provided, and the multiple limiting plates 52 are V-shaped. One side of the limiting plate 52 is inclined towards the outer wall of the walk-in bathtub 8, and the other side is inclined towards the inner wall of the walk-in bathtub 8.

[0030] Specifically, during the loading and unloading of the walk-in bathtub 8, the supporting mechanism 4 connects with the top of the walk-in bathtub 8 and slides down along the lifting mechanism 3 onto the bottom frame 1. Before the walk-in bathtub 8 connects with the bottom frame 1, one end of the opening of the walk-in bathtub 8 first contacts the limiting plate 52. The limiting plate 52 has a V-shaped structure. Under the pressure of the walk-in bathtub 8 on one side, it will rotate around the rotating axis 51, so that the other side rotates to fit against the outer wall of the walk-in bathtub 8, thereby completing the limiting and fixing of the walk-in bathtub 8 and effectively preventing the walk-in bathtub 8 from sliding or shaking.

[0031] In this embodiment, as Figure 2 , 3 As shown, the support mechanism 4 includes a support bracket 42 and a support plate 41. The support bracket 42 has a right-angled triangular structure and is movably connected to the lifting mechanism 3. The support plate 41 is arranged laterally along the width direction of the bottom frame 1, and the length of the support plate 41 is less than the width of the bottom frame 1. The support plate 41 is fixedly connected to the support bracket 42.

[0032] Specifically, when the support mechanism 4 supports the walk-in bathtub 8, its support plate 41 abuts against the side of the opening of the walk-in bathtub 8, and the length of the support plate 41 is less than the width of the bottom frame 1. The purpose of this design is that when the support plate 41 slides along the lifting mechanism 3 to the bottom frame 1, its support plate 41 can be kept at the same level as the bottom frame 1, thereby increasing the contact area between the bottom frame 1 and the walk-in bathtub 8, so that the support plate 41 and the bottom frame 1 can share the weight of the walk-in bathtub 8. The support bracket 42 is set as a right triangle so that the triangle has high stability and can operate stably when the support plate 41 supports the walk-in bathtub 8, ensuring that the walk-in bathtub 8 is raised and lowered smoothly during the up and down sliding, thereby effectively avoiding the problem of shaking during the raising and lowering.

[0033] In this embodiment, as Figure 3 , 4 As shown, the lifting mechanism 3 includes a lifting slide 31, a guide rail 32, a slider 33, a guide plate 34, and a drive assembly 35. The lifting slide 31 is vertically arranged inside the support frame 2, and one side of the lifting slide 31 is fixedly connected to the guide rail 32. The guide rail 32 is symmetrically arranged on the lifting slide 31 and protrudes from the side wall of the support frame 2. The slider 33 is slidably connected to the guide rail 32, and one side of the slider 33 is fixedly connected to the guide plate 34. One side of the guide plate 34 is connected to the drive assembly 35 to drive the guide plate 34 to slide up and down along the guide rail 32.

[0034] Specifically, to facilitate the loading of the walk-in bathtub 8, lifting mechanisms 3 are provided on both sides of the support frame 2. These lifting mechanisms 3 drive the support mechanism 4 to move up and down, facilitating the loading and unloading of the walk-in bathtub 8. When the support mechanism 4 carries the walk-in bathtub 8, the drive assembly 35 drives the support mechanism 4 to slide along the guide rail 32, allowing the support mechanism 4 to stop at any height on the support frame 2, thus facilitating the movement of the walk-in bathtub 8 in and out. The drive assembly 35 includes a rotating handwheel 351, a transmission shaft 352, and a locking device 353. The rotating handwheel 351 is fixed to the top of the guide slide and is rotatably connected to the transmission shaft 352. A shaft 352 is positioned between guide slides, and a nut seat 354 is fitted onto the drive shaft 352. One side of the nut seat 354 is fixedly connected to the guide plate 34. By rotating the handwheel 351, the drive shaft 352 is driven to rotate synchronously, thereby driving the nut seat 354 to slide up and down along the drive shaft 352, and simultaneously driving the guide plate 34 to move synchronously. This controls the support mechanism 4 to slide up and down along the guide rail 32. A locking device 353 is located at the connection between the handwheel 351 and the drive shaft 352. The locking device 353 can fix the drive shaft 352 to stop rotating when it is raised or lowered to a designated position, thereby preventing the support mechanism 4 from sliding up and down. This allows for free control of the raising and lowering position of the walk-in bathtub 8.

[0035] In this embodiment, a push-pull plate 6 is fixedly connected to the top of the support frame 2, and the push-pull plate 6 has a push-pull hole 61 adapted to hand grip.

[0036] Specifically, the push-pull plate 6 facilitates the operation of the transport support by the staff, and the push-pull hole 61 on the push-pull plate 6 allows the staff to grip the push-pull plate 6 and control the movement of the transport support by pulling or pushing.

[0037] To further enhance the convenience of the transport support, swivel casters 7 are provided at the four corners of the bottom of the support frame 2 for auxiliary movement. The swivel casters 7 are equipped with brake pads 71. The function of the swivel casters 7 is to allow workers to push the transport support to quickly transfer the walk-in bathtub 8. At the same time, when it is necessary to brake or stop the transport, the transport support can be stopped simply by stepping on the brake on the swivel caster 7, which facilitates the loading and unloading of the walk-in bathtub 8 and effectively prevents the transport support from shaking.

[0038] In this embodiment, the bottom frame 1 includes crossbeams 11 arranged parallel to each other between the support frames 2, and multiple load-bearing bars 12 connected between the crossbeams 11. The crossbeams 11 and the load-bearing bars 12 are hollow aluminum frame structures, and the distance between the load-bearing bars 12 and the support frames 2 is greater than the width of the support mechanism 4.

[0039] Specifically, the base frame 1 is made of aluminum alloy, which increases its sturdiness. The base frame 1 is composed of multiple crossbeams 11 and load-bearing bars 12 spliced ​​together, which increases the support area for the walk-in bathtub 8 and evenly bears the weight of the walk-in bathtub 8. The distance between the load-bearing bars 12 and the support frame 2 is greater than the width of the support mechanism 4, so that the support mechanism 4 can be kept on the same horizontal plane as the load-bearing bars 12 when it slides down, and thus the base frame 1 can stably support the walk-in bathtub 8.

[0040] The working principle of this utility model:

[0041] When transporting the walk-in bathtub 8, the bathtub is first hoisted by a crane and placed upside down on the support mechanism 4. By controlling the lifting mechanism 3, the support mechanism 4 moves the walk-in bathtub 8 downwards onto the bottom frame 1. Before the walk-in bathtub 8 contacts the bottom frame 1, it contacts the limiting mechanism 5 first. Under its own weight, it presses down one side of the limiting plate 52, causing the other side to rotate and fit against the outer wall of the walk-in bathtub 8, thus completing the front and rear limiting of the walk-in bathtub 8. At the same time, under the left and right limiting action of the support frame 2, the walk-in bathtub 8 is completely fixed on the bottom frame 1, thereby solving the problem of shaking and shifting during transportation, effectively avoiding damage caused by collisions, greatly saving labor transportation costs, saving time and effort, and improving production efficiency.

[0042] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
