Description
Technical Field
[0001] This utility model belongs to the technical field of refrigerator handles, specifically, it relates to a refrigerator handle that is easy to produce in a standardized manner. Background Technology
[0002] In the structure of a horizontal flip-top freezer, the handle is a core component that facilitates the easy opening and closing of the door. It not only allows users to apply force to open the lid but also needs to be compatible with the door shell to ensure sealing performance and sturdiness, while also considering the aesthetic design to enhance the overall product quality. Currently, most horizontal flip-top freezer handles are made of metal, which is strong, durable, and meets the needs of long-term freezer use. However, in standardized production, the processing of metal handles often relies on mold forming technology. Different designs or sizes of handles require the development of separate steel molds. This mold-dependent production model significantly limits the design options for handles: on the one hand, developing new styles requires investment in mold design and manufacturing costs, increasing upfront R&D expenses; on the other hand, the long production cycle of molds slows down the launch of new products, especially hindering small-batch, multi-style customized production.
[0003] In summary, existing technologies have the problem that when the appearance design of the metal handle of a horizontal flip-top freezer is changed, a separate mold needs to be developed, which leads to increased production costs and extended production cycles. Utility Model Content
[0004] In view of this, the present invention provides a refrigerator handle that is easy to produce in a standardized manner, which can solve the problem that when the appearance design of the metal handle of the refrigerator needs to be changed, a separate mold needs to be developed, which leads to increased production costs and extended production cycle.
[0005] This utility model is implemented as follows:
[0006] This utility model provides a refrigerator handle that is easy to manufacture in a standardized manner, including a handle for a horizontal flip-top refrigerator. The handle is fixedly installed to the door shell by a metal bracket and bolts. The metal bracket includes a right-angle connector. The handle has a mounting groove for fitting the right-angle connector. Mounting holes are provided on both sides of the mounting groove, and pre-embedded nuts are installed in the mounting holes. Two sets of through holes are provided at both ends of the right-angle connector. One end of the right-angle connector is fixedly installed by bolts corresponding to the pre-embedded nuts in the mounting groove, and the other end is fixedly installed to the door shell by bolts. The handle is made of a non-metallic material that is formed by cutting.
[0007] The technical advantages of this utility model for a refrigerator handle that facilitates standardized production are as follows: By designing a metal bracket for fixing the handle to the door shell and using pre-embedded nuts and bolts, the installation process is simplified and manufacturing costs are reduced. The precisely fitted mounting groove and right-angle connector structure achieve higher fixing strength and stability, ensuring the consistency and reliability of the handle in standardized production. Furthermore, by limiting the handle material, the problem of traditional metal refrigerator handles requiring mold production for style changes, which is cumbersome and costly, is further solved.
[0008] Based on the above technical solution, the refrigerator handle of this utility model that is easy to produce in a standardized manner can be further improved as follows:
[0009] The metal bracket also includes a door handle reinforcement, which is located on the inside of the door shell and has a threaded hole on top that corresponds to the position of the through hole on the right-angle connector.
[0010] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: By setting up a door handle reinforcement component, the connection strength and tensile strength between the freezer door and the handle are enhanced, solving the problem of loosening or deformation of the connection due to prolonged use or pressure. This further improves the structural stability of the door handle.
[0011] Furthermore, the right-angle connector is fixedly installed near the door shell by bolts through the through holes in the door shell corresponding to the threaded holes on the door handle reinforcement.
[0012] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by fixing the door handle reinforcement with bolts, the accuracy and firmness of the fixing are improved.
[0013] Furthermore, the handle is made of solid wood.
[0014] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by using solid wood, it is easier to change the appearance design of the handle. The solid wood part is easy to cut and process into shape. The aesthetics can also be upgraded by selecting different types of wood. In addition, the wood is easy to drill holes, which can be used to make the same mounting holes and form a unified and compatible connection structure with the metal bracket. This solves the problem that a mold needs to be made every time a new type of metal handle is changed in production.
[0015] Furthermore, the embedded nut is an M4 stainless steel internal and external thread embedded nut, and the bolt used for fixing and installing with the embedded nut is an M4 countersunk bolt.
[0016] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the use of M4 stainless steel internal and external thread pre-embedded nuts and M4 countersunk head fixing bolts improves the fastening force and stability of the bolts and pre-embedded nuts.
[0017] Furthermore, the bolts used to fix the right-angle connector and the door handle reinforcement are M5 countersunk bolts, and the size of the threaded hole on the door handle reinforcement is compatible with the size of the through hole at one end of the right-angle connector and the size of the M5 countersunk bolt.
[0018] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: using M5 countersunk head fixing bolts and matching thread hole sizes enhances the connection strength between the handle and the door shell, and extends the service life of the product.
[0019] Furthermore, the outer corner edges of the right-angle connector are provided with rounded chamfers.
[0020] Furthermore, the right-angled edges of the handle are chamfered.
[0021] The benefits of adopting the above-mentioned improvement scheme are as follows: by setting a chamfered structure on the right-angled edge of the handle, both aesthetics are ensured and the discomfort caused to users by the sharp angles in traditional designs is avoided. The chamfered design improves the tactile feel, making the handle more ergonomic and enhancing the convenience and comfort of using the freezer.
[0022] Compared with existing technologies, the advantages of this utility model for a refrigerator handle that facilitates standardized production are as follows: By designing a metal bracket to fix the handle to the door shell and using pre-embedded nuts and bolts, the installation process is simplified, while manufacturing costs are reduced. The precisely fitted mounting groove and right-angle connector structure achieve higher fixing strength and stability, ensuring the consistency and reliability of the handle in standardized production. Furthermore, by limiting the handle material, the problem of traditional metal refrigerator handles requiring mold production for style changes, which is cumbersome and costly, is further solved.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0036] Example 1:
[0037] like Figure 1-4 The image shows a first embodiment of a refrigerator handle that is easy to manufacture according to the present invention. In this embodiment, a handle 10 is provided on a horizontal flip-top refrigerator. The handle is fixedly installed on the door shell 13 by means of a metal bracket 11 and bolts. The metal bracket includes a right-angle connector 111. The handle has a mounting groove 12 for fitting the right-angle connector. Mounting holes 14 are provided on both sides of the mounting groove. Pre-embedded nuts 15 are installed in the mounting holes. Two sets of through holes are provided at both ends of the right-angle connector. One end of the right-angle connector is fixedly installed by bolts corresponding to the pre-embedded nuts in the mounting groove, and the other end is fixedly installed on the door shell by bolts. The handle is made of a non-metallic material that is formed by cutting.
[0038] In the above technical solution, the metal bracket also includes a door handle reinforcement, which is located on the inside of the door shell and has a threaded hole on its top corresponding to the position of the through hole on the right-angle connector.
[0039] Furthermore, in the above technical solution, the right-angle connector is fixedly installed at the end near the door shell by bolts passing through the through hole opened on the door shell and corresponding to the threaded hole on the door handle reinforcement.
[0040] In the above technical solution, specifically, the handle is made of a non-metallic material that can be directly formed by cutting and processing purchased raw materials, including but not limited to wood, PVC, acrylic, etc.
[0041] Preferably, the handle is made of solid wood, because solid wood is easier to process in an environmentally friendly manner, and its surface texture can present different aesthetic features depending on the type of wood.
[0042] Furthermore, in the above technical solution, the embedded nut is an M4 stainless steel internal and external thread embedded nut, and the bolt used for fixing and installing with the embedded nut is an M4 countersunk bolt.
[0043] Furthermore, in the above technical solution, the bolts used to fix the right-angle connector and the door handle reinforcement are M5 countersunk bolts, and the size of the threaded hole on the door handle reinforcement and the size of the through hole at one end of the right-angle connector are compatible with the size of the M5 countersunk bolt.
[0044] Furthermore, in the above technical solution, the outer corner edge of the right-angle connector is provided with an arc-shaped chamfer 17.
[0045] Furthermore, in the above technical solution, the right-angled edge of the handle is provided with a chamfered structure 17.
[0046] Specifically, the chamfered structure in Embodiment 1 is set on the right-angled edges on both sides of the handle, which serves to prevent collisions and improve the opening and closing feel.
[0047] Optionally, in the above technical solution, the right-angle connector and the door handle reinforcement are made of aluminum alloy. By using aluminum alloy, both lightweight and strong properties are achieved, giving the freezer handle sufficient durability.
[0048] During installation, first fix one end of the right-angle connector to the pre-embedded nut hole on the bottom mounting groove of the handle using an M4 countersunk bolt, and then fix the other end of the right-angle connector to the door handle reinforcement using an M5 countersunk bolt.
[0049] Example 2:
[0050] like Figure 5 , 6 As shown, based on the above-mentioned embodiment 1, the design that differs from embodiment 1 is that the mounting groove is L-shaped to fit both ends of the right-angle connector, which can completely cover the right-angle connector and solve the problem of the right-angle connector being exposed.
[0051] During installation, first assemble the metal brackets, that is, first fix the right-angle connector to the door handle reinforcement with M5 countersunk head bolts, then fasten the right-angle connector to the handle through the mounting groove from the outside, and fix the corresponding holes at the bottom with M4 countersunk head bolts.
[0052] Example 3:
[0053] like Figure 7 As shown, based on the above-mentioned scheme of Embodiment 1, the design that differs from Embodiment 1 is the tilt angle on both sides of the handle and the radius distance of the chamfer structure. The technical effect achieved is to distinguish the aesthetics from Embodiment 1, while providing a different tactile feel by utilizing the designed tilt angle and chamfer structure.
[0054] Example 4:
[0055] like Figure 8 As shown, based on the above-mentioned scheme of Embodiment 1, the design that differs from Embodiments 1 and 3 is the treatment of the arc-shaped chamfer on both sides of the upper surface of the handle and the chamfer structure between the cut edges. The technical effect achieved is to distinguish the aesthetics from Embodiments 1 and 2, while providing different tactile sensations by using the designed chamfer structure.
[0056] Example 5:
[0057] like Figure 9 As shown, based on the above-mentioned scheme of Embodiment 1, the design that differs from Embodiments 1, 3, and 4 is that the front end of the handle is designed with an arc shape and the chamfering treatment between the cut edges is carried out. The technical effect achieved is that it is more aesthetically pleasing than Embodiments 1, 3, and 4, while the chamfered structure provides a different tactile feel.
[0058] Specifically, the principle of this utility model is as follows: It combines a non-metallic, mass-processed material (such as raw wood) with a metal frame. The raw wood portion serves as the decorative element, allowing for different shapes and textures to achieve aesthetically pleasing effects depending on the wood species. The metal frame can also be made of different materials and surface treatments to achieve various matching appearances. Simultaneously, a unified connection interface structure is used, with the metal frame and door handle reinforcements providing stable support. Furthermore, the corresponding opening design and pre-embedded nuts facilitate convenient assembly. This combination enhances the overall durability and aesthetics of the freezer, solving the problem of needing to develop separate molds for changing the appearance design of the freezer's metal handle, which increases production costs and extends the production cycle. It facilitates changing the appearance design while reducing the manufacturer's development costs.
