[0030] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0032] It should also be understood that the terms used in this utility model specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model. As used in this utility model specification and the appended claims, the singular forms "a", "an" and "the" are intended to include plural forms unless the context clearly indicates otherwise.

[0033] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0034] See also Figure 1-10 As shown, this embodiment discloses a transfer device, which includes: a frame 1, a pulley assembly 2 and a plurality of material supports 3; the pulley assembly 2 is connected to the bottom of the frame 1; the plurality of material supports 3 are arranged horizontally and are slidably connected to the frame 1 from top to bottom in sequence; the material supports 3 are provided with a plurality of placement holes 31, and the placement holes 31 are used to accommodate materials 9.

[0035] The transfer device of this embodiment is suitable for transporting cylindrical or tubular components. Furthermore, in this embodiment, the transfer device is used to place and move test connectors used for vacuuming refrigeration systems, specifically, material 9, which is a test connector. In practice, the corresponding material tray 3 is slid so that the placement hole 31 is exposed outside the frame 1. The test connector body is then inserted into the placement hole 31. The top of the material tray 3 contacts and supports the test connector sleeve, allowing the test connector to be securely placed on the material tray 3. The material tray 3 is then slid into the frame 1 to retrieve or place the test connector.

[0036] The transfer device of this embodiment restricts the movement of materials 9 by setting placement holes 31, so that materials 9 are isolated from each other, avoiding mutual wear or collision between materials 9, ensuring the quality and durability of materials 9, and thus improving the sealing of the system; by setting the pulley assembly 2, the frame 1 can be conveniently moved between the transfer starting point and the destination, greatly improving the efficiency of the material 9 transfer operation, while improving the movement smoothness of the material 9, effectively avoiding the risk of materials 9 escaping from the placement holes 31 and colliding with each other due to bumps or shaking, and further improving the reliability of the transfer operation; by stacking a number of material trays 3, the storage capacity of the transfer device is increased, so that more materials 9 can be moved at the same time, further improving the transfer efficiency of materials 9.

[0037] Specifically, the material tray 3 includes a frame 32 and a support plate 33. The frame 32 is vertically penetrated by a through slot 321. The support plate 33 is connected to the top of the frame 32. The support plate 33 is penetrated by a plurality of placement holes 31, and the placement holes 31 are arranged corresponding to the through slots 321. The through slots 321 are arranged corresponding to the placement holes 31, so that the bottom of the placement holes 31 is unobstructed. This allows the protruding parts of the material 9, such as the pipe sleeve and other structures protruding from the main body, to abut against the top of the support plate 33, leaving the bottom of the material 9 suspended in the air. This reduces the contact area between the material tray 3 and the material 9, thereby reducing the friction between the material tray 3 and the material 9 during transportation and loading and unloading, and extending the service life of the material 9.

[0038] Specifically, a plurality of placement holes 31 are distributed in a rectangular array on the support plate 33. The plurality of placement holes 31 are distributed in a rectangular array so that the materials 9 can be neatly arranged and placed in an orderly manner during the transportation process, thereby improving the management and access convenience of the materials 9.

[0039] Specifically, the support plate 33 is screwed to the frame 32. Furthermore, in this embodiment, the support plate 33 is screwed to the frame 32 using self-tapping screws. This screw connection improves the secureness and stability of the connection between the support plate 33 and the frame 32, facilitates the removal and replacement of the support plate 33, and enhances the practicality of the transfer device.

[0040] Specifically, the frame 32 includes four support blocks 322 and four blocking blocks 323. The four support blocks 322 are connected in sequence and end-to-end, forming a through slot 321 between the four support blocks 322. The four blocking blocks 323 are respectively connected to the ends of the four support blocks 322 away from the through slot 321. The support plate 33 is placed on top of the four support blocks 322 and between the four blocking blocks 323. The support blocks 322 are used to support the support plate 33, and the blocking blocks 323 are used to limit the movement of the support plate 33, preventing the support plate 33 from separating from the frame 32, thereby ensuring the placement stability of the material 9.

[0041] In this embodiment, the support blocks 322 and the enclosure blocks 323 correspond to each other and are perpendicular to each other. The support blocks 322 and the corresponding enclosure blocks 323 are constructed of angle iron. The angle iron enhances the squareness and structural strength of the frame 32, making the material tray 3 more stable and reliable when carrying the material 9. The use of angle iron also improves the durability and deformation resistance of the frame 32. The angle iron is low-cost and easy to process and install, which helps reduce the overall manufacturing cost of the transfer device.

[0042] In this embodiment, the pallet 33 is made of polyvinyl chloride (PVC). PVC, a polymer material obtained by polymerization of vinyl chloride monomer, is one of the five most common plastics. PVC has excellent corrosion resistance, making it resistant to a variety of chemicals, including refrigerants and other chemicals that the material 9 may come into contact with in the refrigeration system. PVC also possesses strength and flexibility, providing substantial support for the pallet 33 and the material 9 while absorbing and dissipating some impact forces, protecting the material 9 from damage during transportation. PVC is also relatively inexpensive, helping to reduce the overall manufacturing cost of the transfer device. PVC is also environmentally friendly and recyclable, reducing its environmental impact. Furthermore, the pallet 33 made of PVC exhibits a certain degree of transparency, facilitating observation of the integrity of the bottom of the material 9 and enabling the timely detection of any gaps in the material 9. Therefore, choosing PVC as the material for the pallet 33 not only improves the performance and durability of the transfer device, but also balances cost-effectiveness with environmental considerations.

[0043] It is understandable that in other embodiments, polyethylene, aluminum alloy, carbon fiber composite materials, etc. can be used instead of polyvinyl chloride materials according to actual needs.

[0044] In this embodiment, the frame 1 is a cube-shaped frame 1 formed by connecting twelve square tubes. These hollow, square steel tubes offer high strength while reducing the overall weight of the frame 1 and facilitating its movement. The use of these tubes allows the frame 1 to withstand significant pressure and bending loads, ensuring the overall stability and safety of the transfer device. Furthermore, these tubes are relatively inexpensive, helping to reduce the manufacturing cost of the transfer device.

[0045] Specifically, the frame 1 is equipped with several slide rail assemblies 4, to which the material tray 3 is slidably connected. The slide rail assemblies 4 include two sliders 41 symmetrically arranged on the inner wall of the frame 1, with the ends of the material tray 3 slidably connected to the tops of the sliders 41. The slide rail assemblies 4 are arranged from top to bottom corresponding to the material tray 3, so that each material tray 3 can achieve a sliding connection with the frame 1 via the slide rail assembly 4. The two sliders 41 are symmetrically arranged and connected to two mutually symmetrical inner walls of the frame 1, allowing the material tray 3 to slide smoothly and steadily within the frame 1.

[0046] Specifically, a stopper 42 is provided above the slider 41. The stopper 42 is connected to the inner wall of the frame 1 and has a gap with the slider 41. The material tray 3 is slidably connected between the slider 41 and the stopper 42. The stopper 42 is used to limit the vertical movement of the material tray 3, preventing the material tray 3 from bouncing due to bumps during the movement of the transfer device, thereby ensuring the stability of the material tray 3 and the material 9 on the material tray 3.

[0047] Specifically, the slider 41 is L-shaped and comprises a supporting portion 411 and a limiting portion 412. The supporting portion 411 is used to support the material tray 3, and the limiting portion 412 is perpendicularly connected to the side of the supporting portion 411 away from the center of the frame 1. When the material tray 3 is placed in the frame 1, the bottom, side walls, and top of the material tray 3 are triple-constrained by the supporting portion 411, the limiting portion 412, and the stopper 42, further enhancing the stability of the connection between the material tray 3 and the frame 1.

[0048] In this embodiment, the slider 41 is an angle iron. The angle iron enhances the squareness and structural strength of the slider 41, making the slider 41 more stable and reliable when carrying the material tray 3. The use of angle iron also improves the durability and deformation resistance of the slider 41. The angle iron is low-cost and easy to process and install, which helps reduce the overall manufacturing cost of the transfer device.

[0049] In this embodiment, the stopper 42 is a square tube. A square tube is a hollow, square steel tube that provides high strength while reducing the weight of the stopper 42, preventing it from sagging and potentially jamming the material tray 3. The use of a square tube allows the stopper 42 to withstand significant pressure and bending loads, ensuring the overall stability and safety of the slide rail assembly 4. It is also low-cost and recyclable, aligning with the concept of sustainable development and reducing the consumption and waste of natural resources.

[0050] Specifically, a stopper 43 is provided at one end of the slider 41, and the stopper 43 is provided between the slider 41 and the limiter 42. The stopper 43 limits the sliding range of the material tray 3 and is provided at the end of the slider 41 to avoid the risk of the material tray 3 falling off the slider 41.

[0051] In this embodiment, the blocking member 43 is an iron block, the top and bottom of which are welded to the stopper 42 and the slider 41, respectively. The ends of the blocking member 43 are connected to the stopper 42 and the slider 41, effectively preventing a gap from forming between the stopper 42 and the blocking member 43, which could cause the tray 3 to become stuck. This, to a certain extent, ensures the smooth sliding of the tray 3. The iron block has high wear resistance and can withstand the friction and wear generated by the tray 3 during sliding. This helps to extend the service life of the blocking member 43 and reduce the frequency of replacement and maintenance. Furthermore, the iron block is relatively low in cost, offering a higher cost-effectiveness, meeting the blocking requirements for the tray 3 and reducing the production cost of the transfer device.

[0052] Specifically, the transfer device also includes: a top plate 5a, a bottom plate 5b, a back plate (not marked in the figure), two side plates 6, and a door plate 7; the top plate 5a and the bottom plate 5b are respectively connected to the top and bottom surfaces of the frame 1, the door plate 7 is movably connected to one side of the frame 1, the back plate is connected to the side of the frame 1 away from the door plate 7, and the two side plates 6 are respectively connected to the two side surfaces of the frame 1 adjacent to the door plate 7; the sliding direction of the material tray 3 is parallel to the distribution direction of the door plate 7 and the back plate. The top plate 5a, the bottom plate 5b, the back plate, and the two side plates 6 together constitute a semi-enclosed storage space, and the door plate 7 is used to cover or open the storage space. The door plate 7 covers the storage space, which helps to block external dust or other impurities for the material 9, so as to maintain the cleanliness of the material 9, and at the same time prevent external objects from falling into the storage space and damaging the material 9; the door plate 7 opens the storage space, making it easy to slide the material tray 3 to take and put the material 9. In specific implementation, the door panel 7 is opened to pull out the material tray 3, and then the material 9 on the corresponding material tray 3 is taken out and placed. After taking out and placing the material 9, the material tray 3 is pushed until the material tray 3 abuts the blocking member 43, and then the door panel 7 can be closed.

[0053] Specifically, one end of the door panel 7 is provided with at least two first hinges 71, and the frame 1 is provided with second hinges 11 corresponding to the first hinges 71; the first hinges 71 are hingedly connected to the second hinges 11. Through the first hinges 71 and the second hinges 11, the door panel 7 can flexibly rotate relative to the frame 1, thereby realizing the opening and closing of the storage space, greatly improving the convenience of operating the door panel 7.

[0054] Specifically, the second hinge 11 is provided with a protruding connecting post 111, and the first hinge 71 is provided with a recessed connecting groove 711 corresponding to the connecting post 111. The connecting post 111 is inserted into the connecting groove 711. During implementation, the connecting groove 711 is directly opposite the connecting post 111. Pushing the first hinge 71 so that the connecting post 111 is inserted into the connecting groove 711 completes the installation of the door panel 7. This is a simple and convenient operation that helps improve the production efficiency of the transfer device.

[0055] In this embodiment, a first hinge 71 is disposed on the side wall of the door panel 7, and the first hinge 71 and the second hinge 11 are arranged vertically in sequence. The vertical arrangement of the first hinge 71 and the second hinge 11 eliminates the need for fasteners. Furthermore, under the weight of the door panel 7, the connection of the connecting post 111 ensures that the first hinge 71 does not disengage from the second hinge 11 during movement, simplifying the structure of the door panel 7 and ensuring stable installation.

[0056] It is understandable that in other embodiments, the first hinge 71 and the second hinge 11 can be respectively arranged at the top or bottom of the door panel 7 and the frame 1 according to actual needs, or a slide rail can be used to replace the first hinge 71 and the second hinge 11, that is, the door panel 7 is connected to the frame 1 by a sliding connection.

[0057] Specifically, the first hinge 71 and the second hinge 11 are respectively provided with a first connecting piece 712 and a second connecting piece 112. The door panel 7 is screwed to the first connecting piece 712, and the second connecting piece 112 is screwed to the frame 1. The first connecting piece 712 and the second connecting piece 112 provide installation space, increasing the connection area between the door panel 7 and the first hinge 71, and the connection area between the second hinge 11 and the frame 1, thereby enhancing the structural stability of the transfer device.

[0058] Specifically, the connecting posts 111 of the two second hinges 11 face the same direction, and the connecting slots 711 of the two first hinges 71 face the same direction. Furthermore, the connecting posts 111 extend upward from the second hinge 11, and the connecting slots 711 extend upward from the bottom of the first hinge 71. The aligned orientation of the two connecting posts 111 and the two connecting slots 711 facilitates the detachable connection of the door panel 7, facilitating quick inspection and replacement of the door panel 7.

[0059] Specifically, a first door lock catch 72 is provided at one end of the door panel 7 away from the first hinge 71, and the frame 1 is provided with a second door lock catch 12 corresponding to the first door lock catch 72. The first door lock catch 72 and the second door lock catch 12 can lock the door panel 7 through the door lock, thereby ensuring that the door panel 7 will not be opened due to shaking, bumping, or tilting of the transfer device during the transfer of materials 9, reducing the risk of the door panel 7 hitting the frame 1 and preventing the material tray 3 and the materials 9 from shaking.

[0060] Specifically, the transfer device further includes a handle 8 connected to a side surface of the frame 1. Furthermore, the handle 8 is disposed on a side surface of the frame 1 adjacent to the door panel 7. The handle 8 provides a gripping space, making it easier for a worker to grasp the handle 8 and push the transfer device, thereby improving the user experience of the transfer device.

[0061] Specifically, the pulley assembly 2 includes two moving wheels 21 and two fixed wheels 22. The fixed wheels 22 can only rotate in a fixed direction, providing stable support and movement for the transfer device along a specific route. In scenarios where straight-line travel is required, such as when transferring material 9 in a narrow passage, the high stability of the fixed wheels 22 is particularly important. This prevents the transfer device from deviating from the predetermined route during movement, ensuring the safety and stability of the material 9. The fixed wheels 22 have a relatively simple structure and relatively concentrated force, allowing them to withstand a large weight, helping to disperse the weight and reduce the impact on the transfer device. The moving wheels 21 can rotate freely in all directions, making it more convenient for the transfer device to change direction or bypass obstacles, facilitating easy adjustment of the transfer device's trajectory, and improving the smoothness of the transfer device's movement. The combination of the moving wheels 21 and the fixed wheels 22 ensures a balance between stability and maneuverability, improves the load capacity and durability of the transfer device, and enhances the adaptability and flexibility of the transfer device, enabling the transfer device to meet the needs of various terrains or complex transfer areas.

[0062] Specifically, the two moving wheels 21 are rotatably connected to the end of the frame 1 near the handle 8, and the two fixed wheels 22 are rotatably connected to the end of the frame 1 away from the handle 8. The moving wheels 21 are highly flexible and can easily change direction. The handle 8 and the moving wheels 21 are arranged at the same end to reduce fatigue of the person applying the force, making it easier to apply thrust, especially when changing direction or accelerating. This improves the convenience and comfort of operating the transfer device, and reduces the force transmission path, allowing the transfer device to quickly respond to changes in direction, thereby improving the transfer efficiency of the material 9.

[0063] In this embodiment, the moving wheel 21 and the fixed wheel 22 are respectively made of polyurethane. Polyurethane has excellent wear and fatigue resistance, which enables the polyurethane moving wheel 21 and the polyurethane fixed wheel 22 to maintain stable performance during long-term use, resist wear and tear, reduce performance degradation and replacement frequency caused by wear, and thus extend the service life of the transfer device. Polyurethane produces low noise during operation, making the polyurethane moving wheel 21 and the polyurethane fixed wheel 22 quieter during operation, which helps improve the working environment and reduce noise pollution. Polyurethane has a high load-bearing capacity, allowing the polyurethane moving wheel 21 and the polyurethane fixed wheel 22 to withstand large weights and pressures, providing better support for the frame 1. Polyurethane has excellent elasticity and flexibility, allowing the polyurethane moving wheel 21 and the polyurethane fixed wheel 22 to adapt to various complex environments and road conditions, allowing stable operation on uneven surfaces, reducing vibration and impact, improving the stability and reliability of the transfer device, further improving the smoothness of the material 9 during the transfer process, and helping to reduce wear and tear on the material 9.

[0064] Furthermore, in this embodiment, the diameter of the driving wheel 21 and the fixed wheel 22 is 125 mm, the wheel width is 32 mm, the upper load limit is 140 kg, and the distance between the center of the driving wheel 21 and the fixed wheel 22 and the bottom surface of the frame 1 is 155 mm. The provision of the driving wheel 21 and the fixed wheel 22 increases the load capacity of the transfer device, facilitates the transfer device to transfer more materials 9 at the same time, and to a certain extent improves the transfer efficiency of the materials 9.

[0065] It is understandable that in other embodiments, the material, wheel diameter, wheel width, load limit and distance from the bottom surface of the frame 1 of the moving wheel 21 and the fixed wheel 22 can be adjusted according to actual needs.

[0066] Furthermore, in this embodiment, the side panels 6, top panel 5a, bottom panel 5b, and back panel are 1.2mm thick galvanized sheet metal. The length of the side of the frame 1 where the door panel 7 and back panel are located is 870mm, the width of the side of the frame 1 where the side panels 6 are located is 570mm, and the height of the frame 1 is 1200mm. The length of the support plate 33 is 785mm, the width of the support plate 33 is 540mm, and the thickness of the support plate 33 is 10mm. The number of placement holes 31 on the support plate 33 is 88, and the aperture diameter of the placement holes 31 is 33mm. The dimensions of the transfer device ensure that the transfer device has sufficient storage space and load-bearing capacity, and the overall design takes into account practicality, stability, and durability.

[0067] It is understandable that in other embodiments, the sizes of the side panels 6 , the top panel 5 a , the bottom panel 5 b , the back panel, the frame 1 , the support plate 33 and the placement hole 31 may be adjusted according to actual needs.

[0068] This embodiment provides a transfer device, which restricts the movement of materials by setting placement holes, so that materials are isolated from each other, avoiding mutual wear or collision between materials, ensuring the quality and durability of materials, and thereby improving the sealing of the system; by setting a pulley assembly, the frame can be conveniently moved between the transfer starting point and destination, greatly improving the efficiency of material transfer operations, while improving the smoothness of material movement, effectively avoiding the risk of materials escaping from the placement holes and colliding with each other due to bumps or shaking, and further improving the reliability of transfer operations.

[0069] The above examples are merely used to further illustrate the technical content of the present invention for easier understanding by the reader.
