Description

Technical Field

[0001] This invention relates to the field of refrigeration equipment technology, and in particular to a handle assembly. The invention also relates to a freezer including a handle assembly. Background Technology

[0002] Refrigerators on the market, especially horizontal refrigerators, usually need to be equipped with handles to open and close the doors. Since refrigerator doors are usually heavy and large, the handles are usually large and have certain requirements for bearing strength.

[0003] Existing handle assemblies are usually assembled using fasteners such as bolts, which makes installation relatively complex. Furthermore, the fasteners are prone to deformation after prolonged stress, resulting in low strength and a short service life for the handle assemblies. Summary of the Invention

[0004] The purpose of this invention is to provide a handle assembly that is relatively stable, easy to install, and has high strength.

[0005] To achieve the above objectives, the present invention provides a handle assembly comprising:

[0006] A mounting base is provided on the door body. The mounting base has several mounting parts. The bottom of the mounting part has a limiting groove with the slot facing downward. The front side of the mounting part has a locking protrusion protruding from the door body.

[0007] The handle body has a number of connecting parts that are equal to and correspond one-to-one with the mounting parts. Each connecting part has a claw part and a recess. The claw part is inserted into and engaged with the limiting slot, and the protrusion part is engaged in the recess to connect the handle body and the mounting base.

[0008] In some embodiments of this application, the claw portion has a latch, which is engaged with the slot.

[0009] In some embodiments of this application, the top of the claw portion has a convex arc segment.

[0010] In some embodiments of this application, the claw portion has a reinforcing rib on the side facing away from the slot, and the reinforcing rib is located within the slot.

[0011] In some embodiments of this application, there are multiple reinforcing ribs, and the multiple reinforcing ribs are evenly arranged along the width direction of the claw portion.

[0012] In some embodiments of this application, the mounting portion has a limiting protrusion that protrudes in a direction away from the card protrusion, the limiting protrusion being located on the front side of the slot, the connecting portion having a groove portion, and the limiting protrusion being inserted into the groove portion.

[0013] In some embodiments of this application, the bottom of the handle body has a grip portion, which is convex arc-shaped.

[0014] In some embodiments of this application, the grip portion has a concave arc surface on the side facing the door body.

[0015] In some embodiments of this application, multiple mounting portions are provided, and the multiple mounting portions are arranged on the mounting base along the length direction of the mounting base.

[0016] Another object of the present invention is to provide a refrigerator, which includes a door body and the above-mentioned handle assembly, wherein the front side of the door body has a notch portion that is equal in number and corresponds one-to-one with the number of the mounting portions, the mounting portion is disposed at the notch portion, and the latching protrusion is provided protruding from the notch portion.

[0017] This invention provides a handle assembly, which has the following advantages compared with the prior art:

[0018] The handle assembly provided by the present invention includes a mounting base and a handle body. The mounting base is disposed on the door body and has a plurality of mounting parts. The bottom of the mounting part has a limiting groove with the slot facing downward and a locking protrusion protruding from the door body on the front side of the mounting part. The handle body has a number of connecting parts that are equal to and correspond one-to-one with the mounting parts. The connecting parts have a claw part and a recess. The claw part is inserted into the limiting groove and engages with the limiting groove, and the locking protrusion is engaged in the recess to connect the handle body and the mounting base. Based on the above structure, the handle body adopts a bottom-up installation method. During installation, the claw part is inserted into the limiting groove located at the bottom of the mounting part, and then the protruding part is engaged in the recessed part to complete the assembly of the handle body. That is, this handle assembly does not require fasteners for fixed assembly. The installation through the cooperation of the connecting parts not only limits the mounting base to a predetermined position on the door, but also makes the handle plate firmly installed on the mounting base. The installation is relatively simple, and the insertion of the claw part into the limiting groove can prevent the mounting base or handle plate from sliding horizontally on the door. Secondly, the force direction of the handle body during and after installation is consistent with the force direction of the user, making the handle body not only easier to install, but also able to withstand greater tensile force. The large contact area between the connecting part and the mounting part makes the handle assembly less prone to deformation, with high strength and a long service life.

[0019] In addition, the present invention also provides a freezer that is easy to assemble and has high strength because it uses the above-mentioned handle assembly. Attached Figure Description

[0029] like Figures 1 to 5 As shown, this embodiment of the invention provides a handle assembly, which includes a mounting base 1 and a handle body 2. The mounting base 1 is disposed on a door body 3 and has a plurality of mounting parts 11. The bottom of the mounting part 11 has a limiting groove 111 with the groove 111a facing downward. The front side of the mounting part 11 has a locking protrusion 112 protruding from the door body 3. The handle body 2 has a number of connecting parts 21 that are equal to and correspond one-to-one with the mounting parts 11. The connecting part 21 has a claw part 211 and a recess 212. The claw part 211 is inserted into the limiting groove 111 and engages with the limiting groove 111, and the locking protrusion 112 is engaged in the recess 212 to connect the handle body 2 and the mounting base 1.

[0030] Based on the above structure, the handle body 2 adopts a bottom-up installation method. During installation, the claw part 211 is inserted into the limiting groove 111 located at the bottom of the mounting part 11, and then the protrusion 112 is engaged in the recess 212, thus completing the assembly of the handle body 2. That is, this handle assembly does not require fasteners for fixed assembly. Through the cooperation of the connecting part 21, the mounting base 1 is not only limited to a predetermined position on the door body 3, but the handle plate is also stably installed on the mounting base 1. The installation is relatively simple. Moreover, the insertion of the claw part 211 into the limiting groove 111 can prevent the mounting base 1 or the handle plate from sliding horizontally on the door body 3. Secondly, the force direction of the handle body 2 during and after installation is consistent with the force direction of the user, making the handle body 2 not only easier to install, but also able to withstand greater tensile force. The contact area between the connecting part 21 and the mounting part 11 is large, making the handle assembly less prone to deformation, with high strength and a long service life. It should be understood that this handle assembly is not only suitable for horizontal freezers, but also for other freezer models such as vertical freezers.

[0031] Optionally, such as Figure 4 and Figure 5As shown, in this embodiment, multiple mounting portions 11 are provided, and the multiple mounting portions 11 are arranged on the mounting base 1 along the length direction of the mounting base 1. Based on this, the multiple mounting portions 11 cooperate with the connecting portion 21, which can greatly improve the strength of the handle assembly, so that the handle assembly can withstand greater tensile force; secondly, even if one of the mounting portions 11 or the connecting portion 21 fails, it will not affect the cooperation between the other mounting portions 11 and the connecting portion 21.

[0032] Optionally, such as Figure 3 As shown, in this embodiment, the claw portion 211 has a locking slot 211a, which is engaged with the groove 111a. Based on this, when installing the handle body 2, the claw portion 211 can be easily aligned with the limiting slot 111 and installed.

[0033] Optionally, such as Figure 2 As shown, in this embodiment, the top of the claw portion 211 has a convex arc segment 211b. Thus, the front end of the top of the claw portion 211 is thinner than its middle part, making it easier for the top of the claw portion 211 to be inserted into the limiting groove 111, while the thicker middle part of the claw portion 211 helps the claw portion 211 to be locked into the limiting groove 111, further improving the stability of the handle body 2 after installation.

[0034] Optionally, such as Figure 2 and Figure 3 As shown, in this embodiment, the claw portion 211 has a reinforcing rib 213 on the side facing away from the slot 211a, and the reinforcing rib 213 is located inside the slot 111a. Based on this, the reinforcing rib 213 improves the strength of the claw portion 211, making it less likely to break when the user applies pulling force to the handle body 2.

[0035] Optionally, such as Figure 3 As shown, in this embodiment, multiple reinforcing ribs 213 are provided, and the multiple reinforcing ribs 213 are evenly arranged along the width direction of the claw portion 211. In this way, the multiple reinforcing ribs 213 can further improve the strength of the claw portion 211.

[0036] Optionally, such as Figure 2 As shown, in this embodiment, the longitudinal section of the protrusion 112 along the width direction of the mounting base 1 is a right-angled triangle. The protrusion 112 has a downward-facing first inclined surface, and the recess 212 has a second inclined surface that matches the first inclined surface. Based on this, the protrusion 112 can not only lock the recess 212, but also makes it easy to insert the protrusion 112 into the recess 212 when installing the handle body 2. The installation is more convenient and less strenuous, and the protrusion 112 is not easy to detach from the recess 212 after installation.

[0037] Optionally, such as Figure 2 and Figure 4As shown, in this embodiment, the bottom of the handle body 2 has a grip portion 215, which is convex arc-shaped. Thus, the convex arc-shaped grip portion 215 has a relatively wide grip area, making it easier for the user to grip the grip portion 215 and apply pulling force when opening the cabinet door.

[0038] Optionally, such as Figure 2 and Figure 4 As shown, in this embodiment, the grip portion 215 has a concave arc surface 215a on the side facing the door body 3. Based on this, when the user applies pulling force, the contact area between the fingers and the grip portion 215 is larger, the grip portion 215 is easier to bear force, and the user experience is optimized.

[0039] Optionally, such as Figure 5 As shown, in this embodiment, the mounting portion 11 has a limiting protrusion 113 protruding in the direction away from the card protrusion 112. The limiting protrusion 113 is located on the front side of the slot 111a, and the connecting portion 21 has a recessed portion 214. The limiting protrusion 113 is inserted into the recessed portion 214. In this way, the limiting protrusion 113 can play a further limiting role, and its insertion into the recessed portion 214 can make the connection between the mounting portion 11 and the connecting portion 21 difficult to detach.

[0040] Alternatively, in another embodiment, the limiting protrusion 113 abuts against the groove wall of the recess 214. This results in a larger contact area between the mounting portion 11 and the connecting portion 21 when the user applies pulling force, leading to more even force distribution and increased strength of the handle assembly, making it less prone to breakage. Preferably, the abutting surfaces of both the limiting protrusion 113 and the recess 214 are arc-shaped surfaces.

[0041] This invention also provides a refrigerator, which includes a door body 3 and the aforementioned handle assembly. The front side of the door body 3 has notches 31 that are equal in number and correspond one-to-one with the number of mounting parts 11. The mounting parts 11 are located at the notches 31, and the latching protrusions 112 protrude from the notches 31. Based on this, the mounting base 1 is placed in the notch 31, the latching claw 211 is inserted into the limiting slot 111, and the latching protrusion 112 is engaged in the recess 212. At this time, the mounting base 1 is limited to the notch 31. That is, the cooperation between the mounting part 11 and the connecting part 21 allows the mounting part 11 to be fixedly installed on the door body 3 without the need for any fasteners or mounting positions. The assembly of the handle assembly is convenient and quick, and has high strength.

[0042] The installation method of the handle assembly provided in this embodiment of the invention is as follows: place the mounting base 1 in the notch 31 of the door body 3, insert the claw part 211 into the limiting slot 111, so that the slot 211a is engaged in the slot 111a, pull or push the handle plate upward, so that the protrusion 112 is engaged in the protrusion, and the installation is completed.

[0043] In summary, this invention provides a handle assembly, mainly composed of a mounting base 1 and a handle body 2. The mounting base 1 is disposed on a door body 3 and has a plurality of mounting portions 11. The bottom of each mounting portion 11 has a downward-facing limiting groove 111 with a notch 111a. The front side of each mounting portion 11 has a protruding portion 112 protruding from the door body 3. The handle body 2 has a number of connecting portions 21 that correspond one-to-one with the number of mounting portions 11. Each connecting portion 21 has a claw portion 211 and a recess 212. The claw portion 211 is inserted into and engaged with the limiting groove 111, and the protruding portion 112 is engaged within the recess 212 to connect the handle body 2 and the mounting base 1. Compared with the prior art, this handle assembly has advantages such as being more stable, easier to install, and having higher strength.

[0044] This invention also provides a freezer that, compared with the prior art, has the advantages of convenient and quick assembly and high strength.

[0045] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
