Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 to 6, in an embodiment of the present invention, a disassembling tool 100 includes: a driving head 10, a movable driving member 20 and a limiting member 30.
The driving head 10 is rotated by an external force. The movable driving member 20 serves to transmit torque to the outside when the driving head 10 is rotated. The stopper 30 serves to prevent the movable driving member 20 from being separated from the driving head 10. The stopper 30 is mounted to the driving head 10. The stopper 30 integrally combines the movable driving member 20 with the driving head 10, and prevents the movable driving member 20 from being separated from the driving head 10.
As a specific embodiment, the top of the drive head 10 is configured as a stem. In particular, the shank is provided with a hexagonal structure. The removal tool 100 is used as a working head of a hand tool or a power tool and is rotated by the hand tool or the power tool by being attached to the hand tool or the power tool. As an alternative, the removal tool may also be used as a separate hand tool. Specifically, a grip for a user to hold is formed on the top of the drive head. The user can rotate the driving head by holding the grab handle. For example, the top of the drive head may constitute a T-wrench, an L-wrench, a Y-wrench, or the like.
In a preferred embodiment, the movable drive member 20 has a drive position in which it can transmit torque outwardly and a non-drive position in which it cannot transmit torque outwardly relative to the drive head 10. The movable drive member 20 moves between a drive position and a non-drive position. The bottom of the drive head 10 is formed with a slot 11 into which an external post is inserted to urge the movable drive member 20 from the non-drive position to the drive position. As a specific embodiment, the outer cylinder may be part of the fastener to be removed. When the driving head 10 is butted with the fastener to be disassembled, the insertion of the column of the fastener to be disassembled into the slot 11 pushes the movable driving member 20 to move from the non-driving position to the driving position. As an alternative embodiment, the outer cylinder may not be part of the fastener to be removed. The outer cylinder may act as a separate plunger member to urge the movable drive member 20 from the non-driving position to the driving position by insertion of the plunger member into the socket 11 during docking of the drive head 10 with a fastener to be removed. Of course, the plunger member may be pre-installed in the socket 11 or pre-installed on the fastener to be removed, depending on the adaptation to the different fastener to be removed.
In the drive position, the movable drive member 20 is partially exposed to the outside of the drive head 10. In the non-actuated position, the movable actuator 20 is partially disposed within the socket 11. In the driving position, the movable driving member 20 is exposed to the outer side surface of the driving head 10 so as to be in contact with the fastener to be disassembled, and when the driving head 10 rotates, torque is transmitted to the fastener to be disassembled so as to rotate the fastener to be disassembled. In the non-driving position, the movable driving member 20 moves from the outer side exposed to the driving head 10 to the inside, and the movable driving member 20 is out of contact with the member to be fastened, and the movable driving member 20 cannot transmit torque to the outside.
In one embodiment, the drive head 10 is formed with a channel 12 that guides the movement of the movable drive member 20. The channel 12 has inner and outer channel holes defined at opposite ends thereof. The outer side of the drive head 10 forms the outer passage hole of the passage 12. The passage 12 communicates to the socket 11 through an inner passage hole. The stop 30 is located at least partially on one side of the outer passage hole to limit the position of the movable drive member 20. The driving head 10 is formed with a stopper 13 for limiting the position of the movable driving member 20 at one side of the inner passage hole. Specifically, the movable driving member 20 is a ball. The diameter of the channel 12 is larger than the diameter of the ball. The balls are movable within the channel 12 between an actuated position and a non-actuated position by rolling movement. In a specific embodiment, the channel 12 and the slot 11 are formed by drilling. By controlling the drilling depth, the margin formed by drilling the channel 12 and the slot 11 can constitute a stop. Specifically, the channel 12 and the slot 11 each extend in a linear direction.
As an alternative embodiment, the driving head may not be provided with a stopper at one side of the inner passage hole, and the ball is prevented from being separated from the slot by setting the slot to be smaller than the diameter of the ball.
As an alternative embodiment, the movable drive may also be provided without balls. For example, the movable drive is provided as a slider, which is slidably mounted to the drive head. The slider slides between a drive position and a non-drive position. In particular, the channel acts to guide the movement of the slider. The slider is slidable within the channel. The cross-sectional shape of the channel may match the cross-sectional shape of the portion of the movable drive member located within the channel. Specifically, when the movable driving member 20 is a ball, the passage 12 is formed in a circular hole shape. And the section of the part of the movable driving member positioned in the channel is rectangular, the channel can be rectangular.
As a specific embodiment, an outer passage hole is provided as a mounting hole of the movable driving member 20, and the movable driving member 20 is mounted into the passage 12 through the outer passage hole. After the movable driving member 20 is placed in the channel 12, the limiting member 30 is installed such that the limiting member 30 is at least partially located at one side of the outer channel hole, thereby preventing the movable driving member 20 from being separated from the channel 12 from the installation hole.
The number of the channels 12 and the number of the balls are all a plurality. One ball is located in each channel 12. A plurality of channels 12 are evenly distributed around the axis of rotation of the drive head 10. Specifically, the number of the channels 12 and the number of the balls are 3.
As a specific embodiment, the socket 11 extends in the axial direction of the rotation axis of the drive head 10. The channel 12 extends radially of the axis of rotation of the drive head 10. As a specific embodiment, the channel 12 extends perpendicular to the axis of rotation of the drive head 10. As an alternative, the channel may extend in a direction which is inclined to the axis of rotation of the drive head in the horizontal direction. This arrangement allows the movable drive member to be held in either the drive or non-drive position by gravity in the upright use of the drive head. As a specific embodiment, the center line of the channels 12 intersects the rotational axis of the drive head 10, and the center lines of the plurality of channels 12 intersect the rotational axis of the drive head 10 at a point. As an alternative embodiment, the channel can be deviated from the rotation axis of the driving head in the horizontal direction, and the volume of the lower end of the driving head can be reduced under the condition of keeping the stroke of the movable driving piece unchanged, thereby reducing the material cost.
In a specific embodiment, the limiting member 30 is disposed on the outer periphery of the driving head 10. The stopper 30 is mounted to the driving head 10 by means of a screw connection. The stopper 30 is configured as a sleeve-like structure, and is easy to mount. The limiting member 30 is rotatably mounted to the driving head, and the ball is prevented from separating from the channel 12 by the lower end of the limiting member 30. The lower end of the limiting member 30 is formed with an inner chamfer structure.
As a specific embodiment, the outer wall surface of the driving head 10 is formed with a step structure for positioning the position of the stopper 30. The bottom of the stopper 30 abuts against the stepped surface 14 of the stepped structure, thereby restricting the screwing position of the stopper 30.
As a specific embodiment, the outer wall surface of the limiting member 30 is formed with a flat structure to facilitate the assembly of the driving head 10, the movable driving member 20 and the limiting member 30 by rotating the limiting member 30. Specifically, the stopper 30 is screwed down from the upper end of the drive head 10 to the drive head 10. The limiting member 30 is screwed to the driving head 10 from a side far from the slot 11 to a side close to the slot 11. As an alternative embodiment, the limiting member 30 may be mounted to the driving head from the downward direction to the upward direction.
As an alternative embodiment, the retaining member may be mounted to the drive head by interference fit. The limiting member may not be provided as a sleeve-like structure. For example, the limiting member is configured as a pin or a rod structure. The locating part is installed to the drive head through the cartridge.
As a specific embodiment, in the direction of the rotation axis of the driving head 10, a part of the movable driving member 20 is located above the stepped surface 14 of the stepped structure and another part of the movable driving member 20 is located below the stepped surface 14 of the stepped structure. The outer wall surface of the limiting member 30 is flush with the wall of the outer passage opening of the passage 12 formed by the driving head 10. The bottom of the stop 30 is at a lower elevation than the top of the channel 12. The bottom of the stop 30 is at a lower elevation than the top of the movable drive member 20 to prevent the movable drive member 20 from exiting the channel 12.
Referring to fig. 7 and 8, a tamper bolt 200 includes: the method comprises the following steps: a cover 220 and a bolt body 210 to be disassembled by rotation. The cover 220 is mounted to the bolt body 210.
The bolt body 210 includes: a head 211 and a threaded shaft 212. The head portion 211 and the shaft portion 212 are integrally formed. The shaft 212 is fixed to the bottom end of the head 211. The head 211 has a top formed with a cartridge slot 213. The cartridge slot 213 includes: a central groove 2131 and a drive groove 2132 for carrying torque to rotate the bolt body 210. The wall of the central groove 2131 is recessed outward to form a driving groove 2132. A cylinder 2133 is formed at the bottom of the central groove 2131 in an upward protruding manner. The cover 220 covers at least a part of the driving groove 2132 in a projection in the direction of the rotational axis of the bolt body 210. The cover member 220 is formed with a through hole. In a projection in the direction of the rotational axis of bolt body 210, central groove 2131 is at least partially exposed from the through hole and post 2133 is located within the range of the through hole.
As shown in fig. 1 to 9, when a removal tool 100 is mated with a tamper bolt 200, the removal tool 100 is inserted into the central groove 2131 through the through hole of the cover 220. Specifically, the lower end of the driving head 10 is inserted into the center groove 2131 through the through hole of the cover 220. When the lower end of the driving head 10 is inserted into the central groove 2131, if the movable driving member 20 is located at the driving position, the movable driving member 20 contacts the wall of the through hole of the covering member 220, and the movable driving member 20 can move from the driving position to the non-driving position under the pushing of the wall of the through hole, that is, the lower end of the driving head 10 can freely pass through the through hole of the covering member 220 upwards or downwards. After the lower end of the driving head 10 continues to move downward, the cylinder 2133 of the tamper bolt 200 is inserted into the slot 11 at the lower end of the driving head 10, and contacts and pushes the movable driving member 20 to move from the non-driving position to the driving position. At this time, the movable driving member 20 extends into the driving groove 2132 formed in the wall of the central groove 2131, and the removal tool 100 rotates to drive the anti-removal bolt 200 by outputting a torque outwards through the movable driving member 20. After the cylinder 2133 of the tamper bolt 200 is out of contact with the socket 11, the movable driving member 20 is free to move between the driving position and the non-driving position.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
