Description

Technical Field

[0001] The utility model belongs to the technical field of power tools, and particularly relates to a push-pull switch structure of a power tool. Background Art

[0002] The push-pull switch structures of power tools, such as oscillating shovels, reciprocating saws, and angle grinders, generally include a push button on the surface of the housing, a switch deep inside the housing, and a push rod connecting the push button and the switch. For example, the switch push button, starting power supply, and pull rod in the publication (announcement) number CN217306378U.

[0003] The starting power supply in the above-mentioned CN217306378U uses a push-button type starting button to turn on and off. In actual power tools, switches using a lever or a slider to turn on and off are also used. Since the push button is on the surface of the housing and the switch is deep inside the housing, the force application direction of the push button and the force application directions of the button, lever, and slider of the switch are not in the same horizontal plane. Therefore, when the push button is toggled and the button, lever, or slider of the switch is driven by the push rod, the feedback generated by the on / off action of the button, lever, or slider will be severely weakened during the process of being transmitted from deep inside the housing to the surface of the housing through the push rod, and it is difficult to perceive at the push button, making it difficult for the user of the power tool to perceive whether the switch inside the housing is actually turned on or off. This lack of feedback will affect the use experience of the power tool. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a push-pull switch structure of a power tool to solve the technical problem that the push-pull switch structure of the current power tool causes the lack of feedback on the on / off of the switch at the push button.

[0005] To solve the above technical problem, the utility model provides a push-pull switch structure of a power tool, including: a push rod, which is adapted to slide along a push-pull channel on the inner wall of the housing; a push button, which is arranged on the outer wall of the housing and is connected to the push rod; a gear convex block, which is arranged inside the housing and is located on the sliding path of the push rod, and the push rod squeezes open the gear convex block while being driven by the push button to trigger the switch.

[0006] Further, a push-pull groove adapted to the push rod is formed on the inner wall of the housing; a push-pull limit plate is arranged on the inner wall of the housing to enclose the push-pull channel with the push-pull groove, so that the push rod slides along the push-pull channel.

[0007] Further, a squeezing convex block and a triggering rod are arranged on the push rod, and the push rod is driven by the push button to slide in the push-pull channel. While the triggering rod triggers the switch, the push rod squeezes open the gear convex block through the squeezing convex block.

[0008] Further, the gear bump is located below the push rod, and an arc-shaped convex portion bulges on its upper surface; the squeezing bump is arranged on the bottom surface of the push rod, its bottom surface is flat, and chamfers for cutting in are formed at two bottom corners along the sliding direction of the push rod.

[0009] Further, the trigger rod extends laterally from the push rod and reaches the button of the switch; a guiding chamfer is formed on the surface of the trigger rod facing the button; a button limiting groove is arranged on the surface of the trigger rod facing the button.

[0010] Further, a push button sliding groove adapted to the push button is arranged on the outer wall of the housing; a connecting through hole is formed in the push button sliding groove; a clamping hole is formed in the push rod; a buckle is arranged at the bottom of the push button, and the buckle is adapted to be buckled with the clamping hole after passing through the connecting through hole, so that the push button drives the push rod when sliding in the push button sliding groove.

[0011] The beneficial effect of the present utility model is that the present utility model aims to solve the technical problem that the push-pull switch structure of the current electric tool causes the lack of feedback on the on-off of the switch at the push button. The push-pull switch structure of this electric tool has a push-pull channel opened on the inner wall of the housing, which can ensure that the push rod slides along the push-pull channel. Furthermore, a gear bump is arranged on the sliding path of the push rod. When the push rod is driven by the push button to trigger the switch, the gear bump can be just squeezed open. The feedback of first resistance and then passing generated by the action of the push rod squeezing open the gear bump can be well transmitted to the push button directly connected to the push rod, enabling the user to clearly perceive the on or off of the switch inside the housing.

[0025] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment

[0027] As Figure 1 shown, the present utility model provides a push-pull switch structure of an electric tool, including: a push rod 100, which is adapted to slide along a push-pull channel 300 on the inner wall of a housing 200; a push button 400, which is arranged on the outer wall of the housing 200 and is connected to the push rod 100; a gear bump 500, which is arranged in the housing 200 and is located on the sliding path of the push rod 100, and when the push rod 100 is driven by the push button 400 to trigger a switch 600, the gear bump 500 is squeezed open.

[0028] In the structure of the push-pull switch of this power tool, a push-pull channel 300 is formed on the inner wall of the housing 200, which can ensure that the push-pull rod 100 slides along the push-pull channel 300. Furthermore, a gear bump 500 is arranged on the sliding path of the push-pull rod 100. When the push-pull rod 100 is driven by the push button 400 to trigger the switch 600, the gear bump 500 can be just pushed open. The feedback of first resistance and then passage generated by the action of the push-pull rod 100 pushing open the gear bump 500 can be well transmitted to the push button 400 directly connected to the push-pull rod 100, enabling the user to clearly perceive the connection or disconnection of the switch 600 inside the housing 200.

[0029] As Figure 2 shown, a push-pull groove 310 adapted to the push-pull rod 100 is formed on the inner wall of the housing 200; a push-pull limit plate 320 is provided on the inner wall of the housing 200 to enclose the push-pull channel 300 with the push-pull groove 310, so that the push-pull rod 100 slides along the push-pull channel 300.

[0030] As Figure 2 shown, an extrusion bump 110 and a trigger rod 120 are provided on the push-pull rod 100, and the push-pull rod 100 is driven by the push button 400 to slide in the push-pull channel 300. When the trigger rod 120 triggers the switch 600, the push-pull rod 100 pushes open the gear bump 500 through the extrusion bump 110.

[0031] In at least one embodiment, referring to Figure 3 , the gear bump 500 is located below the push-pull rod 100. Combining Figure 3 , an arc-shaped convex part 510 bulges on its upper surface; the gear bump 500 and the arc-shaped convex part 510 can be made of plastic parts; referring to Figure 3 , the extrusion bump 110 is arranged on the bottom surface of the push-pull rod 100, its bottom surface is flat, and chamfers 111 for cutting in are formed at both bottom corners along the sliding direction of the push-pull rod 100. Through the cooperation of the chamfers 111 for cutting in and the arc-shaped convex part 510, the extrusion bump 110 can have an appropriate sense of block when pushing open the gear bump 500.

[0032] In at least one embodiment, as Figure 2 shown, the trigger rod 120 extends laterally from the push-pull rod 100 and reaches the button 610 of the switch 600; combining Figure 4, a guiding chamfer 121 is provided on the side of the trigger lever 120 facing the button 610, so that when it contacts the button 610, it can be gradually pressed along the guiding chamfer 121, and when separated, it can gradually pop out; a button limiting groove 122 is provided on the side of the trigger lever 120 facing the button 610. When the button 610 is gradually pressed to the bottom along the guiding chamfer 121, it can enter the button limiting groove 122 to prevent the button 610 from accidentally detaching from the trigger lever 120 due to the vibration during the operation of the power tool, resulting in shutdown.

[0033] To ensure that while the trigger lever 120 triggers the switch 600, the push-pull rod 100 just pushes open the gear bump 500 by pushing open the bump 110, refer to Figure 2 and Figure 4 , the distance between the gear bump 500 and the button 610 is adapted to the distance between the pushing-open bump 110 and the button limiting groove 122.

[0034] As Figure 2 shown, a push-button sliding groove 210 adapted to the push button 400 is provided on the outer wall of the housing 200; a connecting through hole 211 is opened in the push-button sliding groove 210; a clamping hole 130 is opened on the push-pull rod 100; a clamping buckle 410 is provided at the bottom of the push button 400, and the clamping buckle 410 is adapted to be buckled with the clamping hole 130 after passing through the connecting through hole 211, so that the push button 400 drives the push-pull rod 100 when sliding in the push-button sliding groove 210. In at least one embodiment, refer to Figure 5 , the housing 200 may include two left and right halves. The push-pull groove 310 and the push-pull limiting plate 320 may be provided in the same half shell, and a trigger lever limiting groove 220 may be opened in the other half shell for jointly forming the limitation of the push-pull rod 100 with the push-pull groove 310. The push-button sliding groove 210 and the connecting through hole 211 may be formed when the two half shells of the housing 200 are butted.

[0035] In summary, the push-pull switch structure of this power tool has a push-pull channel 300 opened on the inner wall of the housing 200, which can ensure that the push-pull rod 100 slides along the push-pull channel 300. Furthermore, a gear bump 500 is arranged on the sliding path of the push-pull rod 100. When the push-pull rod 100 is driven by the push button 400 to trigger the switch 600, the gear bump 500 can be just pushed open. The feedback of a momentary resistance followed by passage generated by the action of the push-pull rod 100 pushing open the gear bump 500 can be well transmitted to the push button 400 directly connected to the push-pull rod 100, enabling the user to clearly perceive the on or off of the switch 600 inside the housing 200.
