Description

Technical Field

[0001] This utility model relates to the field of power tool technology, and specifically to a button mechanism for power tools. Background Technology

[0002] The housing of power tools currently in use consists of two symmetrically arranged left and right halves, which are fixed together by bolts. The power tool's buttons are integrally formed with the left or right half and are located on the left or right half.

[0003] In this button design, the button structure and the housing structure are integrated, both formed in one step during the housing molding process. Because different manufacturers have different design requirements, even the same manufacturer needs to design different molds for the housing when producing different power tools, specifically for different button mechanisms. If a customer slightly modifies the button shape or structure, the entire housing must be redesigned, significantly increasing mold-making costs. Therefore, existing power tools need to be improved to reduce mold-making costs. Utility Model Content

[0004] The technical problem this invention aims to solve is that the existing power tool button mechanism and housing are an integral structure, which increases the cost of mold making. Therefore, this invention provides a novel button mechanism for power tools, which allows for the adaptation and production of different button mechanisms without the need for mold design of the housing each time.

[0005] The technical solution of this utility model is as follows: a button mechanism for a power tool, the power tool including a left half shell and a right half shell, a first slot is provided on the left half shell or the right half shell, a first button mechanism is provided on the first slot, the first button mechanism is provided with protruding ribs on both sides, a slot is provided on the inner wall of the first slot, the protruding ribs are engaged in the slot, and the first button mechanism is provided with a button area adapted to the button switch inside the power tool.

[0006] In the above solution, the button mechanism is set separately in the left or right half of the shell by designing the first slot and the first button mechanism. Whenever the button switch structure changes, only the first button mechanism needs to be redesigned and processed, without having to change the two main components of the left and right half shells. The first button mechanism has a small structure, simple mold opening, and reduces mold opening costs.

[0007] In one possible implementation, the first button mechanism is fixed to the upper surface of the first slot, which is flush with the surfaces of the left and right halves of the housing. The flush transition connection allows for a tighter fit between the first slot and the first button mechanism, resulting in a more stable structure.

[0008] In one possible implementation, the first slot is square, and the slot includes a first slot and a second slot on the two long sides of the inner wall of the first slot. The protrusions include a first protrusion and a second protrusion on the two long sides of the first button mechanism. The first protrusion engages in the first slot, and the second protrusion engages in the second slot. The first slot and the second slot cooperate with the first protrusion and the second protrusion to achieve a snap-fit ​​fixation between the first button mechanism and the first slot.

[0009] In one possible implementation, the first slot includes a left half-slot on the left half-shell and a right half-slot on the right half-shell. The first slot includes a first left half-slot on the left half-slot and a first right half-slot on the right half-slot. The first left half-slot and the first right half-slot are transitionally connected and adapted to the first protruding ridge. The design of the first left half-slot and the first right half-slot is adapted to the split structure of the left and right half-shells.

[0010] In one possible implementation, the first slot includes a left half-slot on the left half-shell and a right half-slot on the right half-shell. The second slot includes a second left half-slot on the left half-slot and a second right half-slot on the right half-slot. The second left half-slot and the second right half-slot are transitionally connected and adapted to the second protrusion. The design of the second left half-slot and the second right half-slot is adapted to the split structure of the left and right half-shells.

[0011] In one possible implementation, the first left half of the slot and the first right half of the slot are symmetrically arranged. This symmetrical arrangement ensures that the fixing fit between the protrusion and the slot is also symmetrical, resulting in uniform force distribution.

[0012] In one possible implementation, the second left half of the slot and the second right half of the slot are symmetrically arranged. This symmetrical arrangement ensures that the fixing fit between the protrusion and the slot is also symmetrical, resulting in uniform force distribution.

[0013] In one possible implementation, the first and second protruding ridges are symmetrically arranged. The symmetrical arrangement of the two ridges ensures that the first button mechanism experiences uniform force when mounted on the housing.

[0014] In one possible implementation, the first button mechanism includes a concave curved surface to improve user comfort.

[0015] In one possible implementation, a button sticker is attached to the surface of the first button mechanism to indicate the function of the corresponding button, facilitating operation. Different button stickers can improve the flexibility of adjusting the indication.

[0016] The beneficial effects of this utility model are as follows: by designing the first slot and the first button mechanism, the button mechanism of the power tool is set independently of the housing body. In this way, each time the button switch is changed, only the first button mechanism needs to be redesigned. The mold design of small parts has low mold cost, which reduces the overall mold cost of the power tool. Attached Figure Description

Detailed Implementation

[0019] To illustrate the technical solution described in this utility model, the following description is provided in conjunction with the accompanying drawings and specific embodiments.

[0020] This invention addresses the high mold-making cost of existing power tools by designing a novel button mechanism. As known from the background art, a power tool includes a left half-shell 1 and a right half-shell 2. A first slot 3 is formed on either the left half-shell 1 or the right half-shell 2. A first button mechanism 4 is fitted onto the first slot 3, with protruding ribs on both sides. A groove is formed on the inner wall of the first slot 3, and the protruding ribs engage with the groove. The first button mechanism 4 has a button area adapted to the push-button switch inside the power tool. Pressing the button area on the first button mechanism 4 activates the push-button switch inside the power tool. Because the first button mechanism 4 is independent of the main body of the power tool housing (left half-shell 1 and right half-shell 2), in practical operation, the color of the first button mechanism 4 can be designed to be different from the main body of the housing for differentiation.

[0021] The shape of the first button mechanism 4 matches the shape of the first slot 3, so that the upper surface of the first button mechanism 4 after being installed on the first slot 3 is flush with the surfaces of the left half shell 1 and the right half shell 2, forming a transitional snap-fit ​​connection with the first slot 3. The transitional connection makes the first slot 3 fit more tightly with the first button mechanism 4 on the shell, and the structure is more stable.

[0022] For ease of processing and assembly, the first slot 3 is square, and its two long sides are respectively provided with a first groove 5 and a second groove 6. The two long sides of the first button mechanism 4 are respectively provided with a first protruding ridge 7 and a second protruding ridge 8. The first protruding ridge 7 is inserted into the first groove 5, and the second protruding ridge 8 is inserted into the second groove 6. The first groove 5 and the second groove 6, together with the first protruding ridge 7 and the second protruding ridge 8, achieve the closing and locking fixation of the first button mechanism 4 and the first slot 3.

[0023] Specifically, the first slot 3 includes a left half-slot on the left half-shell 1 and a right half-slot on the right half-shell 2. The first slot 5 includes a first left half-slot 501 on the left half-slot and a first right half-slot 502 on the right half-slot. The first left half-slot 501 and the first right half-slot 502 are transitionally connected and adapted to the first protrusion 7. This left and right half-slot design is to limit the first slot 3 to be set at the connection between the left half-shell 1 and the right half-shell 2. Theoretically, the first slot 3 can be set on the left half-shell 1 or only on the right half-shell 2, depending on the position of the button switch. However, setting the first slot 3 at the connection between the left half-shell 1 and the right half-shell 2 can maintain the symmetrical design of the left half-shell 1 and the right half-shell 2, resulting in more even force distribution. At the same time, the first left half-slot 501 and the first right half-slot 502 are symmetrically arranged.

[0024] Similarly, the first slot 3 includes a left half-slot on the left half-shell 1 and a right half-slot on the right half-shell 2. The second slot 6 includes a second left half-slot 601 on the left half-slot and a second right half-slot 602 on the right half-slot. The second left half-slot 601 and the second right half-slot 602 are transitionally connected and adapted to the second protrusion 8. The design of the second left half-slot 601 and the second right half-slot 602 is adapted to the split structure of the left half-shell 1 and the right half-shell 2. The second left half-slot 601 and the second right half-slot 602 are symmetrically arranged. The symmetrical arrangement ensures that the fixing fit between the protrusion and the slot is also symmetrical, resulting in uniform force distribution.

[0025] In the above design, the first protruding ridge 7 and the second protruding ridge 8 are symmetrically arranged, and the first protruding ridge 7 and the second protruding ridge 8 are integrally formed with the first button mechanism 4.

[0026] The assembly method of the power tool housing of this utility model is as follows: First, the first button mechanism 4 is assembled onto the left half groove of the left half housing 1 through the first protrusion 7 and the second protrusion 8. Then, the right half housing 2 is closed. The first right half slot 502 and the second right half slot 602 on the right half groove of the right half housing 2 are respectively engaged with the first protrusion 7 and the second protrusion 8, thus fixing the first button mechanism 4 between the left half housing 1 and the right half housing 2. Finally, the left half housing 1 and the right half housing 2 are fixed together with screws, thus realizing the assembly of the first button mechanism 4 and the housing body.

[0027] The directional terms used in the above description are only set for the convenience of description based on the attached diagram and do not impose any substantial limitations on the specific structure.

[0028] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
