The terminology used in the present utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. Words such as "upper", "lower", "front", "rear", etc., indicating an azimuth or a positional relationship are based on only the azimuth or the positional relationship shown in the drawings, and are merely for convenience of description and to simplify the description, and do not indicate or imply that the apparatus/elements referred to must have a specific azimuth or be constructed and operated in a specific azimuth, and thus should not be construed as limiting the present utility model.
The following describes specific embodiments of the present utility model with reference to the drawings.
Referring to fig. 1 and 2, an electric tool assembly according to a preferred embodiment of the present utility model includes an electric tool 100 and a dust collector 200, wherein the dust collector 200 is assembled with the electric tool 100 as a functional attachment, and in this embodiment, the dust collector is assembled with an electric hammer as a dust collection attachment, and dust and debris generated by drilling and chiseling concrete, floors, brick walls, stones, etc. by the electric hammer is collected by the dust collector, thereby purifying the working environment.
The electric tool 100 and the dust collector 200 are fixed by inserting a housing, i.e., the electric tool housing 10 of the electric tool 100 and the dust collector housing 20 of the dust collector 200, as assembly members. The output direction of the electric tool 100 is defined as the front-back direction, the vertical direction is the up-down direction, the rear end of the dust collector housing 20 is reserved with a substantially L-shaped supporting space, the electric tool housing 10 is inserted into the L-shaped supporting space in a plugging manner in the front-back direction and assembled with the dust collector housing 20 into a whole, and an operator only needs to hold either the electric tool 100 or the dust collector 200, thereby facilitating the operation of the operator.
When the electric tool housing 10 is assembled with the dust collector housing 20 in a plugging manner, the lower end surface of the electric tool housing 10 and the upper end surface of the L-shaped supporting space reserved in the dust collector housing 20 are in contact with each other, and one of the two end surfaces can be called as a first joint surface 1, and the other one can be called as a second joint surface 2.
In this embodiment, the first joint surface 1 is a lower end surface of the power tool housing 10, and the second joint surface 2 is an upper end surface of an L-shaped supporting space reserved in the dust collector housing 20. In this way, the pre-guide 21 and the engaging member 22 having the convex shape on the second joint surface 2 can be provided on the dust collector housing 20, and the guide groove 11 and the locking groove 12 having the groove structure on the first joint surface 1 can be provided on the electric tool housing 10. So arranged, when the electric tool 100 does not need to assemble the dust collector 200, the surface of the electric tool housing 10 is relatively smooth and has no convex structure, so that the interference of the convex pre-guide piece 21 and the clamping piece 22 of the electric tool 100 to operators in the independent use process is avoided.
As shown in fig. 3 and 4, the guide groove 11 and the locking groove 12 are recessed from the first joint surface 1 toward the inside of the power tool housing 10 and extend in the front-rear direction to form a groove structure. In order to reduce the area ratio of the groove-shaped structure in the first joint surface 1 and thereby improve the structural strength of the electric tool housing 10, in this embodiment, the locking groove 12 and the guide groove 11 may be overlapped to form a substantially straight guide groove 11 as shown in fig. 4, and the locking grooves 12 arranged on both sides of the guide groove 11, and the locking grooves 12 on both sides may be respectively communicated with the guide groove 11. The specific shape of the guide groove 11 is not limited thereto, and may be set to various shapes according to the actual fitting situation with the pre-guide 21.
In order to equalize the forces between the electric tool housing 10 and the dust collector housing 20 and to improve the stability of the assembly between the electric tool housing 10 and the dust collector housing 20, the guide groove 11 may be provided at a substantially middle position of the first joint surface 1 in the present embodiment, but the guide groove 11 may be provided at a different position on the first joint surface 1 depending on the actual forces between the electric tool housing 10 and the dust collector housing 20.
As shown in fig. 3 and 5, the pre-guide member 21 and the engaging member 22 protrude outward from the second joint surface 2 and extend in the assembling direction to form a convex structure. In the present embodiment, the pre-guide member 21 may be disposed at the front end of the engaging member 22 along the assembling direction, so that the pre-guide member 21 is inserted into the guide groove 11 to perform a guiding function during the insertion and assembling process of the power tool housing 10 and the dust collector housing 20, and then the engaging member 22 is inserted into the guide groove 11 under the guiding of the pre-guide member 21. In this way, the engaging member 22 can form a stable locking structure with the locking groove 12 without deflection under the preliminary guiding action of the preliminary guiding member 21 and the guiding groove 11 forming a guiding pair, thereby locking the electric tool housing 10 and the dust container housing 20 in the front-rear direction.
Referring to fig. 3, 5 and 6, the pre-guide 21 may be fixed to the second joint surface 2 by bonding or screwing or integrally forming. In the present embodiment, a mounting block 211 is fixedly connected or integrally formed at the lower end of the pre-guide 21, and the mounting block 211 is used for fixedly mounting the pre-guide 21 on the second joint surface 2 of the dust collector housing 20. Because the dust collector shell 20 is formed by buckling two symmetrical half shells relatively, an accommodating space matched with the shape and the size of the mounting block 211 is reserved in the dust collector shell 20, the pre-guide piece 21 can be fixed on the second joint surface 2 of the dust collector shell 20 by embedding the mounting block 211 into the accommodating space and integrating the two halves of the dust collector shell 20 together during mounting, the pre-guide piece 21 is easy to damage due to stress, and the dust collector shell 20 is only required to be detached for placing a new pre-guide piece 21 during replacement, so that the replacement cost is lower compared with that of the whole dust collector shell 20.
Referring to fig. 6, the front end of the pre-guide 21 is generally tapered so that the pre-guide 21 can be more easily inserted into the guiding groove 11, but the pre-guide 21 formed by shrinking the width of the front end is not limited to this, and all the pre-guides 21 mentioned in this embodiment are pre-guides 21.
Referring to fig. 3 and 5, the engaging member 22 is slidably disposed on the second engaging surface 2 perpendicular to the assembling direction. The side wall of the dust collector housing 20 is typically provided with a locking button (not shown) which is in linkage connection with the engagement member 22, and an operator operates the locking button to drive the engagement member 22 to slide on the second engagement surface 2. When the engaging member 22 is inserted into the guide groove 11 to a predetermined position along with the pre-guide member 21, an operator operates the locking button to slide the engaging member 22 into the locking groove 12, and the locking surface 221 between the engaging member 22 and the locking groove 12 abuts against each other to form a locking structure between the electric tool housing 10 and the dust collector housing 20 in the assembly direction.
The locking structure of the electric tool housing 10 and the dust collector housing 20 is a side plug structure provided on both side walls thereof in a direction perpendicular to the assembly direction. The side insertion structure includes positioning grooves 13 formed at both sides of the power tool housing 10 and slide rails 23 formed at both sides of the dust container housing 20. When the power tool housing 10 is assembled with the dust container housing 20, the slide rail 23 is also inserted into the positioning groove 13 in the assembling direction as the pre-guide 21 is inserted into the guide groove 11, and the slide rail 23 is also engaged with the positioning groove 13 to form a locking structure of the power tool housing 10 and the dust container housing 20 in a direction perpendicular to the assembling direction.
Referring to fig. 3, the positioning groove 13 is formed on two side surfaces of the electric tool housing 10 along the assembling direction, the positioning groove 13 is also substantially in a "straight" shape, and the specific shape of the positioning groove 13 is not limited thereto, and may be configured into different shapes according to the actual situation of matching with the sliding rail 23.
Referring to fig. 5, a pair of side plates 24 are disposed on two sides of the dust collector housing 20, and the side plates may be integrally formed with the dust collector housing 20, or may be fixedly connected by using glue, screws, or the like, where the two side plates 24 are located on two side surfaces of the electric tool housing 10, and a sliding rail 23 is formed on an inner wall of the side plate 24 along an assembling direction, and the sliding rail 23 is inserted into the positioning slot 13 to form a matching relationship. In order to form a three-dimensional locking structure between the electric tool housing 10 and the dust collector housing 20 and prevent the electric tool 100 and the dust collector 200 from twisting, the slide rail 23 is disposed to be non-coplanar with the second joint surface 2 in a direction perpendicular to the assembly direction, and the non-coplanar means that the slide rail 23 may be above or below the plane of the second joint surface 2, and in this embodiment, the slide rail 23 is disposed above the second joint surface 2 according to the actual structure of the electric tool housing 10 and the dust collector housing 20, so that the locking structure formed by the slide rail 23 and the positioning groove 13 and the locking structure formed by the engaging member 22 and the locking groove 12 together form a three-dimensional locking structure between the electric tool housing 10 and the dust collector housing 20, so that the two are locked together.
In the utility model, a guide pair consisting of a pre-guide piece 21 and a guide groove 11 is arranged between the electric tool shell 10 and the dust collector shell 20, the guide pair guides the electric tool shell 10 and the dust collector shell 20 in a splicing assembly advancing path, so that the clamping piece 22 can be pushed into the locking groove 12 without deflection, the sliding rail 23 can be pushed into the positioning groove 13 without deflection, the electric tool 100 and the dust collector 200 can be firmly locked, the tool head on the electric tool 100 can be inserted into the dust collection head of the dust collector 200 in a positive manner, dust generated by the tool head can be effectively sucked into the dust collection head of the dust collector 200, and in addition, two electric terminals (not shown in the figures) matched with the electric tool 100 and the dust collector 200 can be also in positive butt joint.
The present utility model is not limited to the above-described embodiments. Those of ordinary skill in the art will readily appreciate that many alternatives to the dual speed ratchet wrench of the present utility model are possible without departing from the spirit and scope of the present utility model.
