Description

Technical Field

[0001] The present disclosure relates to the field of electric tools, and in particular to a reciprocating saw and a reciprocating saw. Background Art

[0002] A reciprocating saw is an electric tool that uses a reciprocating saw blade for sawing, and is often used to saw metal plates, pipes, profiles, or cut bevels on steel pipes.

[0003] Reciprocating saws currently on the market usually use a transmission mechanism to convert the torque of the motor into a linear reciprocating motion of the saw blade to achieve cutting. In actual application, when sawing materials that are difficult to saw, the reciprocating sawing action of the reciprocating saw blade will cause the connecting aluminum part axially connected to the reciprocating rod to swing up and down, and this working state is not suitable for materials that are easy to saw. When sawing materials that are easy to saw, the connecting aluminum part does not need to swing up and down, that is, it is necessary to avoid the up and down vibration of the saw blade.

[0004] Therefore, a new structure needs to be designed to limit the up and down swing of the connected aluminum parts. Utility Model Content

DETAILED DESCRIPTION

[0039] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments.

It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described herein are used to be implemented in an order other than those illustrated or described herein.

[0043] In the description of the present disclosure, it is necessary to understand that the orientation or positional relationship indicated by the directional words is usually based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present disclosure and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present disclosure; the directional words "inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0044] At present, the existing reciprocating saws will always have the saw blade shaking in the longitudinal direction during the reciprocating motion. For ordinary materials, the saw blade does not need to shake in the longitudinal direction. The sawing effect of the saw blade can be achieved as long as it moves back and forth along the length direction of the reciprocating rod.

[0045] In order to alleviate the above-mentioned problem, the embodiments of the present disclosure provide a reciprocating saw and a reciprocating saw, which can, under certain circumstances, separate the connecting piece connected to the reciprocating rod from the balancing block setting. In this way, the connecting piece will not have a sliding fit relationship with the balancing block during the process of following the reciprocating rod to move back and forth along its length direction. In this way, the two are separated from each other, the connecting piece will not shake in the longitudinal direction, and further, the saw blade connected to the proximal end of the connecting piece will not shake in the longitudinal direction.

[0046] Reference Figure 1-Figure 4The embodiment of the present disclosure provides a reciprocating saw 001, which includes: a reciprocating rod 10, a motor 20, a transmission component 30, a knife lifting component 40 and a support structure 50; wherein the proximal end of the reciprocating rod 10 is used to connect a saw blade; the motor 20 includes a motor shaft 21; the transmission component 30 includes a gear transmission group 31, a balancing block 32 that slides with the gear transmission group 31 along the length direction of the reciprocating rod 10, and a connecting member 33 connected to the reciprocating rod 10 and having a pulley structure 331 at its bottom; the balancing block 32 is configured to reciprocate in a direction opposite to the rotation direction of the gears of the gear transmission group 31, and the transmission component 30 is driven by the gear meshing between the gear transmission group 31 and the motor shaft 21; the knife lifting component 40 can drive the distal end of the connecting member 33 to move in a direction away from the balancing block 32; the reciprocating rod 10, the motor 20, the transmission component 30 and the knife lifting component 40 are all assembled and fixed by the support structure 50, and the support structure 50 has a knife lifting fulcrum 53, and the knife lifting component 40 is rotatably connected to the knife lifting fulcrum 53.

[0047] Compared with the prior art, the embodiment of the present disclosure adopts a knife lifting component 40 that can drive the distal end of the connecting member 33 to move in a direction away from the balance block 32, and the knife lifting component 40 is rotatably connected to the knife lifting fulcrum 53. In this way, when the distal end of the knife lifting component 40 moves to a position in a direction away from the balance block 32, the saw blade connected to the proximal end of the knife lifting component 40 can adjust the angle downward, and when the saw blade in the reciprocating saw 001 reciprocates to perform sawing action, the connecting member 33 will not contact the balance block 32. In this way, the connecting member 33 will not shake in the longitudinal direction during the reciprocating motion, thereby ensuring that the saw blade will not produce shaking sawing action under certain circumstances.

[0048] The reciprocating saw 001 provided in the embodiment of the present disclosure includes but is not limited to applications in the field of electric tools, and may also be applied to other installation scenarios suitable for sawing processing.

[0049] The knife lifting component 40 of the embodiment of the present disclosure may be a separate structural component, or the knife lifting component 40 of the embodiment of the present disclosure may also be a combined structural component of multiple structures.

[0050] The knife lifting component 40 of the embodiment of the present disclosure can drive the distal end of the connecting member 33 to move in the direction away from the balance block 32. It can be understood that the knife lifting component 40 has the function of lifting or supporting the distal end of the connecting member 33 in the direction away from the balance block 32. Specifically, the embodiment of the present disclosure takes the function of the knife lifting component 40 in supporting the distal end of the connecting member 33 in the direction away from the balance block 32 as an example to further illustrate this scheme.

[0051] In some embodiments, reference Figure 2 and Figure 3The knife lifting component 40 is constructed as a knife lifting knob, which includes a main body 41 and a hand-held portion 42 connected to the upper part of the main body 41. The main body 41 has a knife lifting surface 411, and the distal end of the connecting member 33 has a lap portion 332. The lap portion 332 can elastically press against the knife lifting surface 411 in the longitudinal direction. The knife lifting component 40 adjusts the position of the distal end of the connecting member 33 in the longitudinal direction through the knife lifting surface 411. The hand-held portion 42 is exposed to the external space of the support structure 50 for the user to hold. In this way, the knife lifting knob can move the distal end of the connecting member 33 away from the balance block 32 during the screwing process. The hand-held portion 42 is exposed to the external space of the reciprocating saw 001 for the user to lift the knife rotatably. Further, the knife lifting component 40 is partially exposed to the external space of the reciprocating saw 001. In other words, the knife lifting component 40 is partially exposed to the external space of the casing of the reciprocating saw 001.

[0052] Exemplarily, the overlapping portion 332 is configured as a protruding structure protruding from the distal end surface of the connecting member 33 .

[0053] In some embodiments, further reference is made to Figure 3 and Figure 4 The knife lifting surface 411 is constructed as a spiral plane on the main body 41, and the spiral plane includes a first height support position 4111 and a second height support position 4112, and the overlapping portion moves between the first height support position and the second height support position; the first height support position 4111 and the second height support position 4112 are respectively maintained in a staggered arrangement in the height extension direction of the knife lifting component 40, and the first height support position 4111 and the second height support position 4112 are extendedly connected by the spiral surface; when the overlapping portion 332 is elastically pressed against the second height support position 4112, the bottom pulley structure 331 of the connecting member 33 can be separated from the balance block 32. Thus, in the initial state, the overlap portion 332 is elastically pressed between the housing 50 and the first height support position 4111. At this time, the pulley structure 331 of the connecting member 33 can slide and cooperate with at least part of the structure of the balancing block 32, and the pulley structure 331 can reciprocate along the slope surface in the balancing block 32, which will cause the connecting member 33 and the saw blade to shake in the longitudinal direction. When the blade lifting member 40 is screwed, the overlap portion 332 is elastically pressed between the support structure 50 and the second height support position 4112. At this time, the pulley structure 331 of the connecting member 33 can completely separate from the balancing block 32, and there is no sliding cooperation relationship between the two, so the connecting member 33 and the saw blade will not shake in the longitudinal direction.

[0054] In some embodiments, further reference is made to Figure 2 and Figure 4The reciprocating saw 001 further includes an elastic member 60. A mounting hole 333 is provided at the rear end of the connecting member 33 along the longitudinal direction. One end of the elastic member 60 is connected to the inner bottom wall of the mounting hole 333. The other end of the elastic member 60 is connected to the inner wall of the supporting structure 50. The elastic member 60 is always in a compressed state between the supporting structure 50 and the connecting member 33. In this way, the elastic member 60 can be used to elastically adjust the relatively stable mounting state between the connecting member 33 and the inner wall of the supporting structure 50.

[0055] Exemplarily, the elastic member 60 may be any one of a compression spring, an elastic arm, or a torsion spring.

[0056] Exemplarily, the support structure 50 may be a shell structure having an internal cavity.

[0057] In some embodiments, further reference is made to Figure 3 The second height support position 4112 is lower than the top surface of the body 41, so as to form a first blocking edge 412 at the second height support position 4112, and the first blocking edge 412 is used to define a critical position for the distal end of the connecting member 33 to move upward. In this way, the screwing position of the blade lifting member 40 during the screwing process is controllable, and the problem of the blade lifting member 40 being disengaged from the distal end of the connecting member 33 will not occur.

[0058] In some embodiments, further reference is made to Figure 3 The main body 41 has a second blocking edge 413 at the first height support position 4111, and the second blocking edge 413 is used to limit the critical position of the distal end of the connecting member 33 moving downward. In this way, the screwing position of the knife lifting member 40 during the screwing process is controllable, and the problem of the knife lifting member 40 being disengaged from the distal end of the connecting member 33 will not occur.

[0059] In some embodiments, further reference is made to Figure 4 The gear transmission group 31 includes a first gear 311 and an eccentric wheel 312 located above the first gear 311 and rotating synchronously with the first gear 311. The top surface of the eccentric wheel 312 is connected to a rolling bearing element 313 along the axial direction. The bottom of the connecting member 33 has a matching cavity, and the matching cavity has a third blocking edge 334 and a fourth blocking edge 335 arranged along the length direction of the reciprocating rod 10. The rolling bearing element 313 is sandwiched between the third blocking edge 334 and the fourth blocking edge 335. In this way, in the actual working process, the motor 20 drives the first gear 311 to rotate through the motor shaft 21, and the rotation of the first gear 311 drives the rotation of the eccentric wheel 312. The rotation of the eccentric wheel 312 can promote the reciprocating movement of the rolling bearing element 313 and the balance block 32 along the length direction of the reciprocating rod 10, thereby realizing the reciprocating sawing action of the connecting member 33 and the saw blade.

[0060] The rolling bearing element 313 can be implemented as a needle bearing, a ball bearing, a tapered roller, a spherical roller bearing, and a sleeve. In this embodiment, the rolling bearing element 313 can be implemented as a needle bearing. In some embodiments, further reference is made to Figure 1 and Figure 2 The reciprocating saw 001 further includes a bracket 70, which is used to protect the periphery of the saw blade.

[0061] In some embodiments, further reference is made to Figure 1 and Figure 2 The reciprocating saw 001 further includes a fan 80, which is disposed between the motor 20 and the transmission member 30. In this way, the motor 20 and the transmission member 30 can be subjected to real-time heat dissipation.

[0062] In some embodiments, further reference is made to Figure 1 and Figure 2 The supporting structure 50 of the embodiment of the present disclosure may be a housing of a reciprocating saw 001, and the housing includes a first housing 51 and a second housing 52, and the first housing 51 and the second housing 52 are detachably connected left and right. In this way, the housing 50 can be easily installed and removed, and the replacement and maintenance of the internal structural components can be further facilitated.

[0063] It is worth mentioning that stud slots are reserved in the first shell 51 and the second shell 52, and the first shell 51 and the second shell 52 are connected together by studs. At least 4 stud slots are arranged around the battery compartment to enhance the strength of the battery compartment.

[0064] Combination Figure 1-Figure 4 , and reference Figure 5 , Figure 6 , Figure 7 and Figure 8 The reciprocating saw 001 provided in the embodiment of the present disclosure includes: the aforementioned reciprocating saw 001; and a casing and a battery pack 100; the casing is used as the aforementioned supporting structure 50, and the reciprocating saw 001 is placed in the casing, the casing includes a casing body 91, a grip portion 54 and a battery mounting portion 55, and the casing body 91 and the grip portion 54 extend in the axial direction of the motor; the battery pack 100 is pluggably connected to the battery mounting portion 55, and the reciprocating saw 001 and the battery mounting portion 55 are held at both ends of the grip portion 54.

[0065] Specifically, the battery pack 100 is released with one click, wherein the battery installation portion 55 includes a battery compartment 551, a release mechanism 552 and a pop-up mechanism 553. When the battery pack 100 is locked by the release mechanism 552, the pop-up mechanism 553 is elastically compressed by the battery pack 100. When the release mechanism 552 is triggered, the pop-up mechanism 553 is unlocked by the release mechanism 552 and then recovers its deformation to drive the battery pack 100 to pop out. In addition, the battery pack 100 is inserted and locked, wherein the housing further includes a battery mounting portion 55, the battery mounting portion 55 and the housing body 91 are arranged at both ends of the grip portion 54, the battery mounting portion 55 includes a battery compartment 551 and at least one locking mechanism 554, wherein the locking mechanism 554 is disposed on the side wall of the battery compartment 551, the locking mechanism 554 includes at least one release trigger 5541 and at least one locking assembly 5542, the release trigger 5541 is exposed to the grip channel 90 defined by the grip portion 53, the locking assembly 5542 includes a transmission element and a locking protrusion, the transmission element is transmission-connected to the release trigger 5541, and the locking protrusion can protrude from the side wall of the battery compartment 551 to the battery cavity defined by the battery compartment 551. Wherein, the battery pack 100 is partially exposed to the opening of the battery compartment 551; and / or when the battery pack 100 is placed in the battery compartment 551, the rear end face of the battery pack 100 does not exceed the extension direction of the rear end face of the grip portion 54. It should be pointed out that further reference Figure 5 When the machine is placed on its side on the ground, the side wall of the battery compartment 551 and the side wall 57 of the casing body 91 support the entire machine, and the support planes defined by the battery pack 100 and the side wall of the battery compartment 551 and the side wall 57 of the casing body 91 do not intersect.

Further, the blade lifting member 40 is partially exposed to the external space of the reciprocating saw 001.
