For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0026] See also Figures 1 to 4 A knife switch installation and adjustment device includes: a mounting rod 100, a first sleeve 110 is fixedly provided at one end of the mounting rod 100, the first sleeve 110 is provided with a plurality of first blocks 111, the first blocks 111 are used to be inserted into the corresponding first grooves 201 of the shaft rod 200, the outer periphery of the shaft rod 200 is provided with a bearing 300 with a second groove 301, the mounting rod 100 is movably sleeved with a second sleeve 120, the second sleeve 120 is movably located outside the second sleeve 120, the second sleeve 120 is provided with a plurality of second blocks 121, the second groove 301 is provided with a positioning member 130, the positioning member 130 is used to guide one of the second blocks 121 to rotate to be inserted into the corresponding second groove 301.
[0027] When using the knife switch installation and adjustment device of the above structure, the first clamping block 111 is first inserted into the first groove 201 corresponding to the shaft rod 200, so that the first sleeve 110 is clamped on the shaft rod 200 to fix the position of the installation rod 100, and then the positioning member 130 is installed on the bearing 300, and the second sleeve 120 is moved so that one of the second clamping blocks 121 abuts against the positioning member 130. Finally, the second clamping block 121 is inserted into the second groove 301 corresponding to the bearing 300 through the guidance of the positioning member 130, so that the second sleeve 120 clamps the position of the bearing 300, which is conducive to reducing the difficulty of positioning the second sleeve 120, and the bearing 300 can be rotated while the shaft rod 200 is stabilized by the installation rod 100, so as to adjust the position of the bearing 300 relative to the shaft rod 200, which is conducive to improving the efficiency of adjusting the knife switch. With the above structure, people can install the shaft 200 through the first sleeve 110, and can also use the second sleeve 120 to adjust the position of the bearing 300 after the shaft 200 is installed, so as to adapt to the operating requirements in different scenarios, which is beneficial to improving people's usage experience.
[0028] It can be understood that the number of first blocks 111 corresponding to the first grooves 201 is set to four, and the four first blocks 111 are circumferentially distributed at one end of the first sleeve 110, and the number of second blocks 121 corresponding to the second grooves 301 is set to four, and the four second blocks 121 are circumferentially distributed at one end of the second sleeve 120, thereby increasing the matching position of the first sleeve 110 and the shaft rod 200, and the second sleeve 120 and the bearing 300, which is beneficial to the uniform distribution of the external force acting on the shaft rod 200 to each first block 111, or the uniform distribution of the external force acting on the bearing 300 to each second block 121.
[0029] See also Figure 1 and Figure 2Further, the second groove 301 is a rectangular groove, the positioning member 130 includes a C-shaped plate 131 abutting against the bearing 300, a first vertical plate 132 is provided on the lower surface of the C-shaped plate 131, the first vertical plate 132 abuts against the side wall of the rectangular groove, and a second vertical plate 133 is provided on the upper surface of the C-shaped plate 131, the second vertical plate 133 is located in the extension direction of the side wall adjacent to the rectangular groove, and the second vertical plate 133 is used to limit the rotation position of the second clamping block 121. Specifically, the C-shaped plate 131 is provided with a through hole corresponding to the second groove 301, the second vertical plate 133 is located on the side of the notch extending along the radial direction of the bearing 300, and the second vertical plate 133 is located on the path of the second clamping block 121 rotating clockwise. When in use, first fit the C-shaped plate 131 onto the outside of the shaft rod 200, then drive the first vertical plate 132 to be inserted into the side wall of one of the rectangular grooves, thereby fixing the C-shaped plate 131, so that the through hole is aligned with the second groove 301, and the second clamping block 121 abuts against the end face of the C-shaped plate 131, and finally rotate the second sleeve 120 clockwise so that the second clamping block 121 first passes through the through hole and then abuts against the second vertical plate 133, so that it is convenient for the operator to judge that the second clamping block 121 and the second groove 301 have completed the alignment operation, which is beneficial to the subsequent direct movement of the second sleeve 120, and then the second clamping block 121 is inserted into the second groove 301, which is beneficial to improve the accuracy of the alignment of the second sleeve 120 and the bearing 300, and the C-shaped plate 131 is also beneficial to reduce the damage of the second clamping block 121 to the end face of the bearing 300 during the alignment process.
[0030] See also Figure 1 and Figure 2 Furthermore, a plurality of second vertical plates 133 are provided, and the plurality of second vertical plates 133 are circumferentially distributed on the C-shaped plate 131. Any second clamping block 121 can be rotatably located between two adjacent second vertical plates 133, thereby increasing the matching position of the positioning member 130 limiting the second sleeve 120, which is beneficial for the second vertical plate 133 to guide the corresponding second clamping block 121 to be inserted into the second groove 301, thereby improving the installation efficiency of the second sleeve 120 and the bearing 300.
[0031] Furthermore, the C-shaped plate 131, the first vertical plate 132 and the second vertical plate 133 are an integrated structure, and an elastic layer is provided on the lower surface of the C-shaped plate 131. It is understandable that the C-shaped plate 131, the first vertical plate 132 and the second vertical plate 133 can be formed into one piece by integral injection molding, or fixed together by sheet metal bending, which is conducive to improving the connection strength of the three, thereby ensuring the subsequent positioning member 130 to limit the second sleeve 120. Among them, the elastic layer can be selected as a plastic layer or a silicone layer as needed, so that the positioning member 130 can elastically abut against the bearing 300, which is conducive to a buffering effect on the positioning member 130 and prevents the positioning member 130 from rigidly colliding with the bearing 300.
[0032] See also Figure 1 , Figure 3 and Figure 4 Furthermore, the second sleeve 120 is provided with a first mounting hole 122 and a second mounting hole 123 which are interconnected, the mounting rod 100 is movably matched with the first mounting hole 122, and a mounting space for accommodating the second vertical plate 133 is defined between the outer wall of the mounting rod 100 and the inner wall of the first mounting hole 122. Specifically, after the second clamping block 121 is clamped in the second groove 301, the second vertical plate 133 can be accommodated in the mounting space, which is conducive to reducing the influence of the second vertical plate 133 on the cooperation between the second clamping block 121 and the second groove 301.
[0033] See also Figure 1 , Figure 3 and Figure 4 Further, the mounting rod 100 is provided with a mounting block 140, the mounting block 140 is provided with an arc-shaped groove 141, the second sleeve 120 is provided with an arc-shaped block 124 matched with the arc-shaped groove 141, and the arc-shaped block 124 is connected to the mounting block 140 by bolts. Specifically, the outer peripheral wall of the arc-shaped block 124 is provided with a first threaded hole 125, and the outer peripheral wall of the mounting block 140 is provided with a second threaded hole 143. During installation, the arc-shaped block 124 is first engaged with the arc-shaped groove, and the position of the arc-shaped block 124 is adjusted so that the first threaded hole 125 corresponds to the second threaded hole 143, and finally the first threaded hole 125 and the second threaded hole 143 are connected by bolts, thereby completing the installation of the second sleeve 120 and the mounting block 140.
[0034] See also Figure 1 and Figure 3 Further, the outer peripheral wall of the mounting block 140 is provided with a first clamping hole 142, and the first clamping hole 142 is detachably connected to the first handle 150, and the outer peripheral wall of the mounting rod 100 is provided with a second clamping hole, and the second clamping hole is detachably connected to the second handle 160. Specifically, after the first sleeve 110 is matched with the shaft rod 200, people hold the first handle 150 with one hand to stabilize the position of the shaft rod 200, and hold the second handle 160 with the other hand, so as to facilitate the rotation of the second sleeve 120 to adjust the position of the bearing 300. It can be understood that one end of the first handle 150 and the second handle 160 is provided with a plug hole, and the plug hole is used to connect the rod body externally, thereby increasing the holding positions of the first handle 150 and the second handle 160.
[0035] See also Figure 1 Furthermore, the outer peripheral walls of the first handle 150 and the second handle 160 are provided with an anti-skid texture structure, thereby increasing the friction between the first handle 150 and the second handle 160 and the human hand, thereby preventing people from slipping during the gripping process. It is understandable that the anti-skid texture structure can adopt a diamond texture or a wave texture, thereby increasing the roughness of the outer peripheral walls of the first handle 150 and the second handle 160.
[0036] See also Figure 1 Furthermore, an adapter 170 is provided at one end of the mounting rod 100 away from the first sleeve 110, and the adapter 170 is provided with a third clamping hole 171 for connecting an external electric wrench, so that the external electric wrench is connected through the third clamping hole 171 to rotate the second sleeve 120, thereby facilitating people's experience of using the combination tool.
[0037] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0038] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
