Technical Field

The utility model relates to the technical field of power tools, in particular to a shell assembly of a power tool and the power tool.

Background

In construction, manufacturing and assembly operations, workpieces of material, such as wood, plastic and metal (i.e., to-be-workpieces), must be cut to precise lengths, shapes and sizes. In many instances, power tools are used to cut these workpieces. The power tool is, for example, a miter saw that includes, for example, a base member, a mounting bracket, and an output saw assembly mounted to the mounting bracket. In order to improve the use safety of the miter saw, a stop pin is often arranged on the base component, and when the miter saw is operated to cut a workpiece to be processed placed on the base component, the mounting bracket drives the output saw assembly to directly strike the base component in the rotating process of the mounting bracket relative to the base component through the stop effect of the stop pin on the mounting bracket.

Specifically, because the rotational connection of the mounting bracket and the base member is provided with the spring for enabling the output saw assembly to face away from the direction of the base member, the end of the mounting bracket, which is far away from the base member, is tilted away from the direction of the base member, so that a package box with a larger height is required to be provided when the housing assembly of the miter saw is packaged, the packaging cost is increased, the transportation volume is increased, and the transportation efficiency is reduced.

Detailed Description

In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.

Embodiment one:

referring to fig. 1, a schematic structural diagram of a housing assembly of a power tool according to a first embodiment of the present utility model is shown. 2-6, a power tool includes, for example, an output saw assembly 110, the output saw assembly 110 including a drive assembly and a cutting blade drivingly connected to the drive assembly; the housing assembly includes, for example, a base member, a mounting bracket 10, and a locking member 30. The mounting bracket 10 is movably connected with the base component, and one end of the mounting bracket 10 away from the base component is connected with the output saw assembly 110; the locking member 30 is mounted on either one of the base member and the mounting bracket 10, and the locking member 30 is also used to connect the other one of the two; wherein, when the mounting bracket 10 is in the locked state by the locking component 30, the first whole machine height formed by combining the base component and the mounting bracket 10 is smaller than at least one second whole machine height in the unlocked state.

In a specific example, a power tool such as the miter saw 100, where the mounting bracket 10 is used to mount the output saw assembly 110 of the miter saw 100, it is common that the mounting bracket 10 is rotatably connected to the base member, and the output saw assembly 110 includes a motor, a cutting blade, and other parts, so that the output saw assembly 110 has a relatively large weight, and the mounting position of the output saw assembly 110 on the mounting bracket 10 is combined with the characteristic that the output saw assembly 110 is mounted on the mounting bracket 10, that is, the end of the mounting bracket 10 far from the base member, so that the mounting bracket 10 approaches to the workpiece placement end surface near the base member under the action of gravity, and then, in order to avoid the output saw assembly 110 striking the base member, a torsion spring is often disposed at the position where the mounting bracket 10 and the base member are rotatably connected, and the end of the mounting bracket 10 provided with the output saw assembly 110 is moved by the elastic force of the torsion spring toward the direction far from the workpiece placement end surface, that is tilted relative to the base member, and is at a relatively high point of the whole power tool.

Further, in combination with the actual packaging situation, the end of the mounting bracket 10 far from the base member is the highest point of the whole machine when the power tool is normally placed on a horizontal table top, that is, the distance formed between the end and the base 213 in the base member is the largest. Since the above-mentioned mounting bracket 10 is raised at the end by the torsion spring, the required accommodating height for packaging the entire miter saw 100 increases, and if the output saw assembly 110 is not mounted on the mounting bracket 10, the mounting bracket 10 is further raised away from the end of the base 213 assembly, thereby further increasing the height of the package box to be packaged, which means that the cost of the package to be packaged increases.

Thus, in combination with the present disclosure, for ease of understanding, the mounting bracket 10 is divided into the mounting end portion 11 and the connection end portion 12, the mounting end portion 11 is used for mounting the output saw assembly 110, the connection end portion 12 is connected with the base 213, and the base 213 and the mounting bracket 10 are simultaneously connected by the locking member 30 so that the mounting bracket 10 is in the locked state, at which time the distance formed between the base 213 and the mounting end portion 11, that is, the distance between the base member and the mounting end portion 11 is reduced compared with the normal state, that is, the unlocked state, so that the distance between the base member and the mounting end portion 11 is shortened, that is, the whole machine height formed by combining the base member and the mounting bracket 10 is reduced from the second whole machine height to the first whole machine height compared with the unlocked state, thereby realizing reduction in the accommodation height of the packing box, and further reduction in the material expenditure of the packing, and reduction in the packing cost for the packing. Wherein, for ease of understanding, the overall height may be denoted by H.

In short, the greater the distance between the mounting end 11 and the base member, the greater the overall height of the power tool.

Preferably, the locking member 30 is removably connected with at least one of the base member and the mounting bracket 10.

In a specific example, for convenience of operation, the locking member 30 may be detachably connected to both the base 213 and the mounting bracket 10, and since the locking member 30 is mainly used to resist the elastic force of the torsion spring mentioned above, the structure thereof is easily deformed and damaged in long-term use, so that the locking member 30 is simultaneously detachable from both the base 213 and the mounting bracket 10, so that the locking member 30 can be replaced in time, and the mounting bracket 10 is ensured to be in a stable and reliable locking state.

Further, the base member includes, for example, a tie bar 22 and a processing platform 21. One end of the pull rod piece 22 is rotatably connected with the mounting bracket 10; the processing platform 21 is connected with the other end of the pull rod piece 22, and the mounting bracket 10 is positioned above the processing platform 21 in the vertical direction; wherein the locking member 30 is used to connect the pull rod 22 with the mounting bracket 10.

In a specific example, the pull rod 22 is slidably connected to the processing platform 21, specifically, the pull rod 22 and the processing platform 21 are disposed in parallel with each other between the processing end faces of the workpiece to be processed, that is, when the pull rod 22 slides relative to the processing platform 21, the distance between the pull rod 22 and the processing end faces remains unchanged, and during this movement, the pull rod 22 drives the mounting bracket 10 to move above the processing platform 21.

Further, the pull rod member 22 and the mounting bracket 10 are connected through the locking member 30, so that the mounting end 11 and the processing platform 21 can be pulled to be close to each other, namely, the height H of the whole machine is reduced, and the position of the mounting bracket 10 relative to the processing platform 21 can be adjusted in the process of sliding the pull rod member 22, so that the housing assembly or the miter saw 100 can be packaged better, and the packaging difficulty is reduced.

Specifically, the processing platform 21 includes, for example, a base 213, a rotating platform 211, and an extension platform 212. The base 213 is provided with a mounting surface, one end of the base 213 is in sliding connection with the corresponding end of the pull rod piece 22, when the pull rod piece 22 is adjusted to slide relative to the base 213, the mounting bracket 10 rotationally connected with the pull rod piece 22 is driven to move above a processing and placing platform formed by combining the rotating platform 211 and the extending platform 212, so that workpieces mounted on the mounting bracket 10 can be cut at different positions of the workpieces to be processed placed on the processing and placing platform; the rotary processing platform 21 is rotatably connected to the mounting surface; the extension table 212 is provided on the mounting surface and is provided adjacent to the rotary processing platform 21; wherein the extension table 212 is detachably connected to the base 213. The workpiece is, for example, a cutting member, in particular a cutting saw blade.

In one embodiment, the workpiece to be processed is often placed on the rotating platform 211, and the cutting treatment is performed on different parts of the workpiece by rotating the rotating platform 211. When the size of the workpiece to be processed is large, the extension table 212 and the rotary table 211 are combined to support the workpiece to be processed together.

Although the related art has presented a solution in which the extension table 212 is added to the base 213 to increase the support of the workpiece to be processed, there is a problem in that the extension table 212 and the base 213 are often integrally formed, so that on one hand, the overall weight of the miter saw 100 is increased, the difficulty of handling the miter saw 100 by a user is increased, and portability is reduced; on the other hand, it will be appreciated that the extension table 212 is usually disposed on two sides of the rotary table 211, which results in that during the movement of the miter saw 100, it is unavoidable that the extension table 212 collides with other objects in the actual environment, and if the damage is serious, the effect of stable support of the rotary table 211 on the workpiece is affected, thereby reducing the cutting efficiency of the miter saw 100 on the workpiece. For example, the base 213 is an aluminum product.

Thus, in connection with the present solution, by removably engaging extension table 212 with base 213. On the one hand, when the extending table 212 is damaged in structure, for example, when the supporting end surface for supporting the workpiece to be processed is deformed or the end part of the extending table 212 far away from the rotating table 211 is deformed to form a convex block protruding towards the supporting end surface, the stable supporting effect of the rotating table 211 on the workpiece to be processed is prevented from being influenced, and at the moment, only the extending table 212 can be replaced without replacing the base 213, so that the replacement cost is reduced; on the other hand, for example, during the handling of the miter saw 100, the extension table 212 may be pre-detached to avoid collision of the extension table 212.

Preferably, the locking member 30 comprises, for example, a first locking element and a second locking element. The first locking member is connected to the base 213; the second locking piece is connected to the mounting bracket 10 at a position corresponding to the first locking piece; wherein, when the mounting bracket 10 is in the locking state, the first locking piece is inserted into or clamped with or screwed with the second locking piece. The first locking member and the second locking member are matched in a simple and reliable manner, so that the switching of the adjusting mounting bracket 10 between the locking state and the unlocking state is convenient to operate.

Preferably, the mounting bracket 10 is used for mounting a workpiece; the mounting bracket 10 is rotatably connected with the base 213 to drive the workpiece to approach or separate from the base 213; when the mounting bracket 10 rotates relative to the base 213, the second locking member is disposed corresponding to one of the at least one locking positions of the first locking member.

In one embodiment, it will be appreciated that the miter saw 100 may be used with a workpiece of a size or model that is, a cutting blade, and the distance between the mounting bracket 10 and the processing platform 21 needs to be reasonably adjusted to avoid that the mounting bracket 10 cannot be in a locked state due to an oversized cutting blade, or that the mounting bracket 10 is in a locked state due to an undersize selected cutting blade, but the distance between the mounting end 11 and the processing platform 21 is too large, i.e., the overall height H is too large, so that the packaging space is increased to increase the packaging cost.

Then, in combination with the above analysis, a plurality of locking positions may be set, and the setting positions of the plurality of locking positions are sequentially set along the rotation direction of the mounting bracket 10 around the base 213, so that after the mounting bracket 10 rotates by a certain angle, the second locking piece can be matched with the locking position at the corresponding position, so as to lock the mounting bracket 10 to the corresponding position, and further ensure the locking effect on the mounting bracket 10, and further refine the locking state of the mounting bracket 10, so that the distance between the mounting end 11 and the base 213 corresponding to the locking state can be adjusted according to the power tools of different models, thereby reasonably adjusting the overall height H and maximally reducing the cost expenditure of the packaging box.

Preferably, either one of the first locking member and the second locking member is a locking lever 31, and the other is at least one locking hole 32 that mates with the locking lever 31; the housing assembly further comprises, for example, a shielding member 40, the shielding member 40 being adapted to shield the at least one locking hole 32. Specifically, on the one hand, when the locking lever 31 is separated from the locking hole 32, shielding the locking hole 32 by the shielding member 40 improves the appearance of the housing assembly, and also prevents processing scraps generated during processing by the miter saw 100 from remaining in the locking hole 32 in the unlocked state, thereby obstructing the maintenance of the stable locking state of the subsequent mounting bracket 10; on the other hand, the shielding of the locking hole 32 by the shielding member 40 limits the occurrence of the condition that the locking lever 31 is accidentally inserted into the locking hole 32 during the actual machining process, ensuring the machining process to be performed; in addition, the blocking function of the blocking component 40 on the locking rod 31 can also prevent the mounting bracket 10 from driving the output saw assembly 110 too close to the processing platform 21 to cause the cutting saw blade to strike the processing platform 21.

It should be noted that the mounting bracket 10 is in a state in which the mounting end of the mounting bracket 10 is closer to the processing end surface of the processing platform 21 than in a state in which the lock lever 31 enters the lock hole 32 and the lock lever 31 is stopped by the shielding member 40.

Preferably, the first locking member is a locking aperture 32; the shielding member 40 includes, for example, a shielding member 41 and a resetting member 42. Specifically, the shielding member 41 may be a shielding plate, and the shielding member 41 is provided to the base 213 and serves to shield the locking hole 32; the resetting piece 42 is arranged in the mounting groove of the base 213, and the resetting piece 42 is matched with the shielding piece 41; the return member 42 has an elastic force that maintains the shutter 41 to block the lock hole 32. Specifically, the restoring member 42 may be a restoring torsion spring, one end of which is connected to a mating hole on the shielding member 41, and when the mounting bracket 10 is required to be in a locked state, a user is required to pull the shielding member 41 out of a position shielding the locking hole 32 against the elastic force of the restoring torsion spring, so that the locking lever 31 enters the corresponding locking hole 32. In short, the stability of the shutter 41 to block the locking hole 32 is ensured by the elastic force of the return member 42.

Preferably, the shielding member 41 is provided with a toggle member 43 at a position remote from the locking hole 32. The operation of opening the locking hole 32 by the shutter 41 is made more labor-saving and convenient by pulling the toggle 43.

Preferably, the shutter 41 is rotatably connected to the base 213 to open or block the locking hole 32; wherein the shutter 41 prevents the second locking member from entering the locking aperture 32 when the mounting bracket 10 is in the unlocked state. Further ensuring that the processing of the miter saw 100 proceeds smoothly.

Preferably, the base 213 also includes an auxiliary handle 23, for example. One end of the pull rod 22 mates with the output saw assembly 110 of the miter saw 100; the auxiliary handle 23 is arranged at one end of the pull rod piece 22 away from the output saw assembly 110; wherein the auxiliary handle 23 is rotatably connected to the pull rod member 22 about a first axis.

Further, in order to facilitate the adjustment of the sliding of the pull rod 22 relative to the base 213, it is common to fix the handle on the pull rod 22, however, the problem is that the user can only hold the handle in a fixed holding position to realize pulling the pull rod 22 relative to the base 213, so that the user cannot adjust the position of the handle relative to the pull rod according to the use habit thereof to apply a pulling force to the handle, thereby reducing the user experience and the pulling efficiency.

Further, the handle is often vertically fixedly connected to the pull rod 22, i.e., the two are combined to form an "L" shape. Thus, when the user applies a pulling force to the handle, the pulling force cannot be completely converted into a force pushing the pull rod member 22 to slide with respect to the base 213, further reducing the adjustment efficiency.

In one embodiment, in combination with the above, the user may also handle the miter saw 100 by holding the handle. There are various ways of carrying the miter saw 100, and in particular, the base 213 includes, for example, a base 213, a swivel platform 211, and an extension platform 212. The base 213 is provided with a mounting surface; the rotary platform 211 is rotatably connected to the mounting surface; the extension table 212 is provided on the mounting surface and adjacent to the rotation table 211, and a handle structure is provided on the extension table 212, so that a user can carry the miter saw 100 by holding the handle structure. Specifically, there may be two extension tables 212, and the two extension tables 212 are disposed on both sides of the rotation table 211, respectively, so that both hands hold the two handle structures, respectively, to achieve the effect of carrying the end miter saw 100. However, the problem with this handling is that, due to the larger size of the base 213, the heavy weight motor, etc. is disposed on the output saw assembly 110 in combination with the distribution of the parts of the miter saw 100, and the pull rod 22 is connected to the base 213, such that the output saw assembly 110 is disposed above the base 213, when the above-mentioned handling method is adopted, the center of gravity of the miter saw 100 is higher, and is difficult to maintain stable during handling, and in addition, the handling method in which two hands are opened to hold two handle structures results in more effort during handling by the user, further reducing the efficiency of the handling method.

Thus, the miter saw 100 can be carried by grasping a handle provided on the pull rod 22. However, the fixed connection between the handle and the pull rod 22 in the related art results in that the user can only maintain a fixed pulling posture when carrying the miter saw 100, which reduces the user's experience, and the fixed connection between the handle and the pull rod 22 is easy to break the connection.

Therefore, in combination with the technical scheme, by means of the rotary connection between the auxiliary handle and the pull rod piece 22, in the process of applying a pulling force to the pull rod piece 22 to adjust the pull rod piece 22 to slide relative to the base 213, the auxiliary handle 23 and the pull rod piece 22 can form a straight-line arrangement, so that the pulling force applied by a user can be completely converted into an effective pushing force for pushing the pull rod piece 22 to slide, and the adjusting efficiency is improved; in addition, during the process of carrying the entire miter saw 100, the characteristic that the auxiliary handle 23 is rotatably connected with the pull rod member 22 can be used to reduce the influence of the inertial force generated by the rotation of the output saw assembly 110 relative to the pull rod member 22 on the holding of the auxiliary handle 23 by the user in a dynamic carrying environment, that is, the auxiliary handle can rotate relative to the pull rod member 22 to offset part of the inertial force, so that the process of carrying the miter saw 100 is easier.

Embodiment two:

referring to fig. 1, a schematic structure of a power tool according to a second embodiment of the present utility model is shown.
