Description

Technical Field

[0001] The utility model relates to the technical field of electric tool auxiliary tools, in particular to an electric tool bracket base structure. Background Art

[0002] When using power tools, they are usually operated by manual grip, which requires a high level of arm strength and work experience from the user. Based on this, power tool auxiliary brackets have appeared in the prior art. One of the auxiliary brackets is patent document 2024207521795 previously applied for by the applicant's legal person other company, which enables the power tool to be raised and lowered, moved forward and backward, and adjusted in angle to facilitate user operation.

[0003] In order to facilitate the position transfer of this type of auxiliary bracket, it is provided with corresponding rollers, but the position of the rollers is not adjustable. The width between the outer ends of the two rollers is greater than the width of the base, and the power tool is not above the base. The setting of the rollers makes it difficult for the power tool to operate on the wall. That is, due to the presence of the rollers, the edge of the base cannot rest against the wall, which limits the working range of the power tool. However, the rollers are necessary components for the position transfer of the auxiliary bracket. Therefore, the applicant has made further improvements. Utility Model Content

[0029] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0030] See also Figure 1-Figure 7 A power tool stand base structure includes a base body 1, and a plurality of front rollers 2 are installed at the front end of the base body 1. As one embodiment, a wheel axle is installed at the front end of the base body 1, and corresponding front rollers 2 are installed at both ends of the wheel axle.

[0031] The base body 1 serves as the base of the auxiliary bracket, and it bears the overall weight of the components arranged above it, including the power tool. Therefore, the bottom surface of the base body 1 can be designed to be a flat surface. During operation, the bottom surface of the base body 1 is directly in contact with the ground to avoid the weight being borne by the roller. In this embodiment, the lower edge of the front roller is flush with or higher than the bottom surface of the base body 1. Of course, it can also be slightly lower than the bottom surface of the base body 1. There is a certain amount of buffering and deformation space for the roller.

[0032] One or more connecting rods 3 are installed on the base body 1. As one embodiment, there are at least three connecting rods 3. The first connecting rod 3 extends toward the left side of the base body 1, the second connecting rod 3 extends toward the right side of the base body 1, and the third connecting rod 3 extends toward the rear side of the base body 1. Figure 1 、 Figure 3 shown.

[0033] In this embodiment, a corresponding roller 4 is installed on each connecting rod 3. The roller 4 on the connecting rod 3 extending toward the left and right directions of the base body 1 serves as the rear roller of the auxiliary bracket, and its outer diameter can be larger than the outer diameter of the front roller 2; the roller 4 on the connecting rod 3 extending toward the rear side of the base body 1 serves as an auxiliary support wheel, which saves the user more effort when transferring the position of the auxiliary bracket.

[0034] In this embodiment, two extension pieces 5 are fixed to the rear of the base body 1 , each extension piece 5 is fixed with a corresponding first connecting member 6 , a cross bar 7 is fixed between the two extension pieces 5 , and the cross bar 7 is also fixed with a first connecting member 6 .

[0035] The connecting rods 3 extending to the left and right of the base body are respectively installed on the first connecting piece 6 on the extension piece 5, and the connecting rod 3 extending to the rear side of the base body 1 is installed on the first connecting piece 6 on the cross bar 7.

[0036] In this embodiment, at least two positioning holes or positioning grooves 61 are provided on the first connecting member 6, and a through hole 31 is provided on the connecting rod 3. A pin (not shown in the figure) is arranged at the through hole 31. The pin cooperates with the positioning hole or positioning groove 61 to position the connecting rod 3, so that the connecting rod 3 has a first state of expansion and a second state of folding.

[0037] For the method of opening the positioning hole on the first connecting member 6, it is necessary to first pull out the pin shaft, align the through hole with the corresponding positioning hole, and then insert the pin shaft so that the pin shaft passes through the positioning hole and the through hole 31, thereby positioning the connecting rod.

[0038] Regarding the method of opening a positioning groove on the first connecting member 6, it is only necessary to design the through hole 31 as a long through hole for the pin to move, that is, the length of the long through hole is greater than the outer diameter of the pin. After the connecting rod 3 moves to the corresponding state position, the pin is moved and pushed into the corresponding positioning groove 61 to position the connecting rod 3.

[0039] like Figure 4As shown, an implementation method of opening a positioning groove 61 on the first connecting member 6 is provided, and its position layout is that one positioning groove 61 is on the outside and one positioning groove 61 is on the inside. The positioning groove 61 on the outside corresponds to the first state in which the connecting rod 3 is unfolded, and the positioning groove 61 on the inside corresponds to the second state in which the connecting rod 3 is folded; the opening of the connecting hole is similar, and it is only necessary to change the groove into a hole.

[0040] Furthermore, when a positioning groove is provided on the first connecting member 6, since the pin does not need to be withdrawn, an elastic unit (not shown in the figure), such as a spring, can be provided between the pin and the inner end wall of the connecting rod 3 to tighten the pin through the elastic unit to improve the positioning effect of the connecting rod 3.

[0041] The connecting rod 3 extending toward the rear side of the base body 1 has a roller 4 provided thereon for supporting the auxiliary bracket after it tilts toward the rear side (when the auxiliary bracket is transferred, the auxiliary bracket is tilted toward the rear side so that the roller touches the ground and the base body is off the ground). Therefore, when the connecting rod 3 is in the second state of expansion, the angle between it and the bottom surface of the base body 1 is set to 30-60 degrees. For example, if it is designed to be 45 degrees, when the base body is placed on the ground, the connecting rod 3 is in an upward state, such as Figure 2 shown.

[0042] For the connecting rod 3 extending toward the rear side of the base body 1, a second connecting member 81 is fixed to its outer end, and the corresponding roller 4 is rotatably set on the second connecting member 81. A locking member 82 is rotatably connected to the second connecting member 81. When the outer end of the locking member 82 abuts against the outer wall of the roller 4, the roller 4 is locked. When locking, the locking member 82 can be flipped down; when unlocking, the locking member 82 can be flipped up.

[0043] As one option, the contact portion between the locking member 82 and the roller is designed to be arc-shaped.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
