Description

Technical Field

[0001] This invention relates to the field of metal casing installation technology for household appliances, and specifically to a metal casing crimping pliers for small household appliances. Background Technology

[0002] Small household appliances typically use a plastic casing with a metal structure, providing both protection and aesthetics. The metal casing is often secured to the plastic component using bent metal clips. This process requires bending the metal clips to secure the metal casing to the plastic. Currently, production often involves manually bending the metal clips with ordinary pliers or using specialized metal clip bending equipment. Bending the metal clips manually with ordinary pliers easily scratches the metal casing, increasing the defect rate; it is also labor-intensive and inefficient. Using specialized metal clip bending equipment is costly, and the equipment's specialized nature and poor versatility make it unsuitable for multi-variety, small-batch production. Summary of the Invention

[0003] Therefore, in response to at least one of the above problems, the present invention provides a metal casing crimping pliers for small household appliances.

[0004] This invention is implemented using the following scheme:

[0005] This invention proposes a metal casing snap clamp for small household appliances, comprising an upper snap clamp, a lower snap clamp, a pressure rod, and a rotating shaft. The upper snap clamp and the lower snap clamp are pivotally connected via the rotating shaft, and the snap clamp can clamp the fastener to be snapped at the jaws between the upper and lower snap clamps. The key feature is that the pressure rod is displaceably installed in the cavity between the upper and lower snap clamps, and after the upper and lower snap clamps clamp the fastener to be snapped, the pressure rod can be actuated to extend and bend the metal snap of the fastener.

[0006] In one embodiment, a guide sleeve is provided in the cavity between the upper clamp and the lower clamp. The guide sleeve is a hollow structure with an inner cavity. The shape of the inner cavity matches the shape of the pressure rod, so that the pressure rod can be movably installed in the inner cavity.

[0007] In one embodiment, the upper clamp includes a first handle and two first side plates connected to the first handle. The two first side plates are arranged parallel to each other, and the gap between the two first side plates is suitable for accommodating the pressure rod. Push grooves are formed on the two first side plates. The push grooves are obliquely arranged elongated grooves. One end of the pressure rod is connected to a push shaft, which is accommodated in the push groove. The lower clamp includes a second handle, so that when the upper clamp and the lower clamp are pressed together by the handle, the push groove can push the push shaft to move, thereby driving the pressure rod to move.

[0008] In one embodiment, the clamping clamp includes a base plate, a second handle connected to one end of the base plate, and two second side plates extending upward along a portion of the length of both sides of the base plate, thereby forming an installation notch at the end of the base plate away from the second handle, and a guide sleeve is disposed within the installation notch; the ends of the two second side plates near the second handle are connected to the second handle; the two second side plates are arranged parallel to each other, forming an installation space between the two second side plates, and the two first side plates are installed within the installation space.

[0009] In one embodiment, the ends of the two first side plates away from the first handle are connected to an upper plate, which is perpendicular to both first side plates. The end of the upper plate away from the first handle is perpendicularly connected to an end panel, which has a clearance opening. The shape and size of the clearance opening are suitable for the pressure rod to extend out from the clearance opening. When the upper and lower clamps are closed, the end panel is located at the opening of the guide sleeve away from the second handle, and the fastener to be pressed can be clamped between the end panel and the base plate.

[0010] In one embodiment, a silicone sheet is provided on the end of the base plate away from the first handle.

[0011] In one embodiment, the upper clamp is provided with a first pivot hole, and the lower clamp is provided with a second pivot hole. The first pivot hole and the second pivot hole are concentrically arranged and both pivotally engage with the rotating shaft. The first pivot hole is located at the end of the two first side plates away from the first handle, and the second pivot hole is located at the end of the two second side plates away from the second handle.

[0012] The technical solution provided by this invention has the following technical effects:

[0013] This invention provides a metal shell crimping pliers for small household appliances, which is a universal crimping tool for small household appliances. It can save a lot of manpower and ensure the quality of the crimped products. Moreover, the tool is highly versatile, has low manufacturing cost, and is suitable for multi-variety, small-batch production. Attached Figure Description

[0022] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0023] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0024] like Figure 1-8 As shown, this embodiment provides a small appliance metal casing snap clamp 1, including an upper snap clamp 10, a lower snap clamp 20, a clamping rod 30, and a rotating shaft 40. The small appliance metal casing snap clamp 1 is used to snap and bend the fastener 50 to be snapped. The lower snap clamp 20 is provided with a second pivot hole 211, and the upper snap clamp 10 is provided with a first pivot hole 111. The second pivot hole 211 and the first pivot hole 111 are concentrically arranged and both are pivotally engaged with the rotating shaft 40, thereby enabling a pivotal connection between the upper snap clamp 10 and the lower snap clamp 20, and allowing the fastener 50 to be snapped to be clamped in the jaws between the upper snap clamp 10 and the lower snap clamp 20, as shown. Figure 6-7 As shown, the pressure rod 30 is displaceably installed in the cavity between the upper clamp 10 and the lower clamp 20. After the upper clamp 10 and the lower clamp 20 clamp the fastener 50 to be pressed, the pressure rod 30 can be actuated to translate and bend the metal buckle 51 of the fastener 50 to be pressed.

[0025] A guide sleeve 22 is disposed in the cavity between the upper clamp 10 and the lower clamp 20. The guide sleeve 22 is a hollow structure with an inner cavity 221. The shape of the inner cavity 221 matches the outer shape of the pressure rod 30, so that the pressure rod 30 can be movably installed in the inner cavity 221. In this embodiment, the pressure rod 30 is a cuboid structure with a square cross-section, and the inner cavity 221 also has a square cross-section. The guide sleeve 22 can guide the movement of the pressure rod 30, thereby making the movement of the pressure rod 30 more accurate.

[0026] The upper clamp 10 includes a first handle 14 and two first side plates 11 connected to the first handle 14, the two first side plates 11 being arranged parallel to each other. The ends of the two first side plates 11 away from the first handle 14 are connected to an upper plate 12, the upper plate 12 being perpendicular to both first side plates 11. The end of the upper plate 12 away from the first handle 14 is perpendicularly connected to an end panel 13. The end panel 13 is provided with a clearance opening 131, the shape and size of which are suitable for the clamping rod 30 to extend from the clearance opening 131. A first pivot hole 111 is provided at the end of the two first side plates 11 away from the first handle 14.

[0027] The clamping clamp 20 includes a base plate 25, a second handle 23 connected to one end of the base plate 25, and two second side plates 21 extending upward along a portion of the length of both sides of the base plate 25, thereby forming a mounting notch 27 at the end of the base plate 25 away from the second handle 23; the ends of the two second side plates 21 near the second handle 23 are connected to the second handle 23; the two second side plates 21 are arranged parallel to each other, forming a mounting space 24 between the two second side plates 21; a second pivot hole 211 is provided at the end of the two second side plates 21 away from the second handle 23. A guide sleeve 22 is provided within the mounting notch 27.

[0028] The upper clamp 10 and the lower clamp 20 are pivotally connected via a pivot 40, and the two first side plates 11 are installed within the installation space 24. When the upper clamp 10 and the lower clamp 20 are closed, the end panel 13 is located at the end of the guide sleeve 22 away from the second handle 23, and the fastener 50 to be pressed can be clamped between the end panel 13 and the base plate 25. The gap between the two first side plates 11 is suitable for accommodating the pressure rod 30, and the pressure rod 30 is movably installed between the two first side plates 11. Two first side plates 11 are provided with push grooves 112, which are long grooves set at an incline. One end of the pressure rod 30 is connected to a push shaft 31, which is accommodated in the push groove 112. When the upper clamp 10 and the lower clamp 20 are pressed together by the handles, the push groove 112 can push the push shaft 31 to move, thereby driving the pressure rod 30 to move. This causes the pressure rod 30 to extend out of the guide sleeve 22 through the relief opening 131 and bend the metal buckle on the fastener 50 to be pressed, which is clamped between the end panel 13 and the base plate 25. In this embodiment, the metal buckle on the fastener 50 to be pressed is an iron buckle. After the fastening is completed, the handles of the upper clamp 10 and the lower clamp 20 are manually opened to remove the finished product, and one cycle of action is completed.

[0029] like Figure 6-7 As shown, preferably, a silicone sheet 26 is provided on the base plate 25 at the end away from the second handle 23. When the upper clamp 10 and the lower clamp 20 are pressed together by the handle, the fastener 50 to be pressed is clamped between the silicone sheet 26 and the end panel 13, the silicone sheet 2 is compressed, and at the same time the push shaft 31 is pushed by the groove 112 to slide and drive the pressure rod 30 to extend, as shown. Figure 6 As shown, as the upper clamp 10 and lower clamp 20 continue to close, the silicone sheet 26 continues to be compressed, thereby further clamping the fastener 50 to be pressed. Simultaneously, the pressure rod 30 extends further, bending the metal buckle of the fastener 50, as shown. Figure 7 As shown. The silicone sheet 26 protects the fastener 50 from damage during the fastening process, and also enhances the friction between the fastener 50 and the small appliance metal casing fastener pliers 1, preventing the fastener 50 from coming off during the fastening process. The silicone sheet 26 can be attached to the base plate 25, for example, by adhesive. By using silicone sheets 26 of different thicknesses, this tool can be adapted to fastening requirements of products with different thicknesses.

[0030] Of course, in other embodiments, the pressure rod 30 can also be actuated and translated in other ways. For example, an electric push rod is provided in the cavity between the upper clamp 10 and the lower clamp 20, and the electric push rod is connected to the pressure rod 30. When the upper clamp 10 and the lower clamp 20 are closed, the electric push rod is triggered to drive the pressure rod 30 to move, thereby bending the metal buckle 51 of the fastener 50 to be pressed. However, in this embodiment, the push shaft 31 is driven to move by the push groove 112, thereby driving the pressure rod 30 to move. The structure is simpler, the manufacturing cost is lower, and it is easier to realize small-batch production.

[0031] The small appliance metal shell crimping pliers 1 provided in this embodiment are general-purpose small appliance metal shell crimping tools, which can save a lot of manpower and ensure the quality of crimped products; moreover, the tool is highly versatile, has low manufacturing cost, and is suitable for multi-variety, small-batch production.

[0032] Although the invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the invention without departing from the spirit and scope of the invention as defined in the appended claims, all of which shall be within the scope of protection of the invention.
