Disclosure of Invention
Problems to be solved by the invention
As a driving tool, an impact driver, an impact wrench, and the like are known. The impact driver is provided with a socket (chuck) for inserting and mounting a fixed hexagonal screw head (phi 6.35 mm). On the other hand, a tip tool such as a socket is also inserted into the impact driver. Such a tip tool is provided with a hexagonal screw head for insertion into an impact driver, and can be used by inserting the hexagonal screw head into a chuck of the impact driver and locking the hexagonal screw head. However, since a large torque is applied to the tip tool such as the socket during use, there is a problem in that the hexagonal screw head is bent.
Next, an impact wrench as a driving tool will be described with reference to fig. 3. As shown in fig. 3, the impact wrench 7 includes a socket portion 71 for receiving a tip tool such as a socket. The insertion portion 71 is provided with a positioning portion (through hole) 72. In general, a tip tool (not shown) for an impact wrench is provided with a fitting portion having an inner peripheral surface shape corresponding to the outer peripheral surface shape of the insertion portion 71 of the impact wrench 7, and the fitting portion is provided with a through hole along a lateral direction (a direction perpendicular to the axis) with respect to the axis. When the tip tool for an impact wrench is inserted into the impact wrench 7, a metal pin (not shown) is inserted into the through-holes of the fitting portion of the tip tool for an impact wrench in a state in which the position of the through-hole 72 of the impact wrench 7 is aligned with the position of the through-hole of the fitting portion, and a rubber O-ring (not shown) is covered on the through-holes of the fitting portion. Thereby, the tip tool for the impact wrench is prevented from falling off.
However, in the conventional tip tool for an impact wrench, such a pin and an O-ring are required to prevent the tip tool from falling off, and therefore, there is a problem in that it takes time to insert the tip tool and operability is poor. In addition, if the O-ring is deteriorated and broken during use of the impact wrench 7, the O-ring is liable to fall off, which causes a problem of safety. In addition, even if the pin or the O-ring is not used, the tip tool for the impact wrench is pressed against the fastener to be hardly detached when the fastening operation of the bolt, the nut, or the like is performed, but if the fastening operation is made to idle, the tip tool for the impact wrench is detached. Therefore, in the conventional tip tool for an impact wrench, a pin and an O-ring are generally used.
The invention aims to provide a sleeve which can be quickly embedded and fixed with an inserting part of a driving tool.
Solution for solving the problem
In order to solve the above-described problems, according to the 1 st aspect of the present invention, there can be provided a socket to be fitted and fixed to a socket portion of a driving tool in which at least 1 positioning portion is recessed, and comprising a socket main body, a switching member, and at least 1 positioning means, the socket main body having an axis, a working portion and a fitting portion arranged along an extending direction of the axis, a fastener being connected to the working portion, the fitting portion having a fitting space into which the socket portion is fitted, the switching member being movable in the extending direction of the axis and being mounted to the fitting portion so as to be rotatable about the axis, the positioning means having a 1-receiving portion, a 2-receiving portion, and a positioning member, the 1-receiving portion penetrating the fitting portion in a lateral direction with respect to the axis, the 2-receiving portion being formed in the switching member and being opposed to the fitting portion, the positioning member being movably received in the 1-receiving portion, the positioning member having a first portion protruding from the switching member, the first receiving portion being located in the protruding portion from the switching member 1-receiving portion, and the positioning member being located in the protruding portion 2-receiving portion, and being located in the protruding portion, the fitting portion being displaced from the switching member-receiving portion when the first receiving portion is located in the switching portion, and is located in the protruding portion from the position.
ADVANTAGEOUS EFFECTS OF INVENTION

Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to this.
Reference is made to fig. 1 to 6. As shown in fig. 1 to 6, the socket according to an embodiment of the present invention is fitted and fixed to the insertion portion 71 of the driving tool 7. At least 1 positioning portion 72 is recessed in the insertion portion 71. The sleeve is constituted by at least a sleeve body 1, a switching member 2 and at least 1 positioning unit 3.
The sleeve body 1 has an axis 11, and a working portion 12 and a fitting portion 13 arranged along the extending direction of the axis 11. A fastener such as a bolt or a nut is connected to the working portion 12. The fitting portion 13 has a fitting space 131 into which the insertion portion 71 is inserted. The switching member 2 is attached to the fitting portion 13 so as to be movable in the extending direction of the axis 11 and rotatable about the axis 11.
The ratio of the length of the fitting portion 13 parallel to the axis 11 to the length of the working portion 12 is 0.4 to 0.6. The switching member 2 is fitted to the fitting portion 13. The distance from the outer peripheral wall 25 of the switching member 2 to the axis 11 is substantially equal to the distance from the outer peripheral wall 25A of the working portion 12 to the axis 11.
At least 1 positioning unit 3 has a1 st housing portion 31, a 2 nd housing portion 32, and a positioning member 33, respectively. The 1 st housing portion 31 penetrates the fitting portion 13 in a lateral direction with respect to the axis 11 (a direction perpendicular to the axis 11). The 2 nd housing portion 32 is formed on the switching member 2 and faces the fitting portion 13.
The positioning member 33 is movably accommodated in the 1 st accommodating portion 31. A part of the positioning member 33 protrudes from the 1 st housing portion 31. The positioning member 33 is here a ball (sphere). The 1 st and 2 nd housing parts 31 and 32 are through holes. The 2 nd housing portion 32 has a smaller aperture than the 1 st housing portion 31 so as to prevent the positioning member 33 from falling off.
When the switching member 2 is in the lock position, the position of the 1 st housing portion 31 is shifted from the position of the 2 nd housing portion 32 (the position facing in the direction perpendicular to the axis 11). The switching member 2 is pressed against the positioning member 33 so as to cover the opening of the 1 st housing portion 31. A part of the positioning member 33 pressed by the switching member 2 protrudes from the fitting space 131, and is engaged with the positioning portion 72 to be fitted and fixed.
When the switching member 2 is in the open position, the 1 st housing portion 31 and the 2 nd housing portion 32 overlap in a direction transverse to the axis 11. When the positioning member 33 receives a force from the fitting space 131, a part of the positioning member 33 extends into the 2 nd housing portion 32, but does not extend into the fitting space 131. That is, when a force in a direction perpendicular to the axis 11 is applied to the fitting space 131, a part of the positioning member 33 moves into the 2 nd housing portion 32. When the positioning portion 72 is disengaged from the positioning member 33, the insertion portion 71 can be pulled out from the fitting space 131.
The number of the positioning portions 72 may be at least one, and in the present embodiment, the number of the positioning portions 72 is two. The two positioning portions 72 are openings which are symmetrically arranged and communicate with each other. In the present embodiment, the number of positioning units 3 is two, and at least one positioning unit 3 may be used. The two positioning units 3 are symmetrically arranged about the axis 11. When the switching member 2 is in the lock position, the two positioning members 33 are fitted to the two positioning portions 72, respectively.
The shapes of the insertion portion 71 and the positioning portion 72 are not limited to this.
Reference is made to fig. 1 to 6. As shown in fig. 1 to 6, the switching member 2 is mounted rotatably about the axis 11 (i.e., rotatably in the circumferential direction of the fitting portion 13) while being movable in a direction parallel to the axis 11 of the sleeve body 1. For example, for switching between the lock position and the open position of the switching member 2, the relative positions of the 1 st housing portion 31 and the 2 nd housing portion 32 can be changed by moving the switching member 2 in the direction parallel to the axis 11. However, if the relative positions of the 1 st housing portion 31 and the 2 nd housing portion 32 overlap due to vibration or the like at the time of use of the driving device 7, the switching member 2 unexpectedly moves to the open position, and the sleeve may be detached from the driving device 7. On the other hand, if the switching member 2 is rotatably attached around the axis 11 of the sleeve body 1, the relative position of the 1 st housing portion 31 and the 2 nd housing portion 32 can be changed not only in the direction parallel to the axis 11 but also in the circumferential direction of the fitting portion 13. In this way, the position of the 1 st housing portion 31 and the position of the 2 nd housing portion 32 are shifted by two different operations, and thus the switching member 2 can be suppressed from unexpectedly moving to the open position.
The sleeve comprises a positioning member 51. The positioning member 51 is positioned in the fitting portion 13 (the positioning member 51 of the present embodiment is a ring clamped to the fitting portion 13). The outer diameter of the working portion 12 is larger than the outer diameter of the fitting portion 13, a1 st step 61 is formed at the junction between the working portion 12 and the fitting portion 13, and a predetermined distance is provided between the 1 st step 61 and the positioning member 51 along the direction parallel to the axis 11. The switching member 2 is positioned between the 1 st step 61 and the positioning member 51. The predetermined distance is greater than the length of the switching member 2 parallel to the axis 11. The switching member 2 is slidable in the direction of the axis 11.
The 1 st contact portion 21 and the 2 nd contact portion 22 parallel to the axis 11 are provided on both sides of the switching member 2. The 1 st abutment portion 21 is sandwiched between the 2 nd abutment portion 22 and the 1 st step 61.
When the switching member 2 is rotated (rotated in the circumferential direction of the fitting portion 13), after the 1 st housing portion 31 is arranged in parallel with the axis 11 and in line with the 2 nd housing portion 32, the switching member 2 is in the open position when the 1 st contact portion 21 is in contact with the 1 st step 61, and the switching member 2 is in the lock position when the 2 nd contact portion 22 is in contact with the positioning member 51.
The sleeve body 1 has a1 st identification portion 41. The 1 st mark 41 is parallel to the axis 11 and corresponds to the 1 st housing 31. The switching member 2 has a2 nd identification portion 42. The 2 nd identifier 42 is parallel to the axis 11 and corresponds to the 2 nd housing 32. Therefore, the user can know the relative positions of the 1 st and 2 nd housing portions 31 and 32 in the circumferential direction of the switching member 2 by merely viewing the 1 st and 2 nd identification portions 41 and 42. When the switching member 2 is rotated, the relative positions of the 1 st housing portion 31 and the 2 nd housing portion 32 in the circumferential direction of the switching member 2 can be superimposed (made coincident) when viewed from the axis 11 direction. By rotating the switching member 2 only in this way, the relative positions of the 1 st housing portion 31 and the 2 nd housing portion 32 in the direction parallel to the axis 11 do not overlap (do not coincide), and thus the lock position is maintained. When the switching member 2 is further moved in the direction parallel to the axis 11 in a state where the switching member 2 is rotated to match the relative positions of the 1 st housing portion 31 and the 2 nd housing portion 32, the switching member is opened when the relative positions of the 1 st housing portion 31 and the 2 nd housing portion 32 in the direction parallel to the axis 11 are matched. On the other hand, when viewed from the axis 11 direction, the relative positions of the 1 st housing portion 31 and the 2 nd housing portion 32 in the circumferential direction of the switching member 2 can be made non-overlapping (made non-uniform). In this state, even if the switching member 2 is moved in the direction parallel to the axis 11, the relative positions of the 1 st housing portion 31 and the 2 nd housing portion 32 in the circumferential direction of the switching member 2 do not coincide, and therefore, the switching member is always in the lock position.
Preferably, the fitting portion 13 has a 2 nd step 62, and the switching member 2 has a base 23. Both ends of the elastic member 53 are respectively abutted against the 2 nd step 62 and the base 23, and the 2 nd abutment 22 always has a force toward the positioning member 51. If no external force acts on the switching member 2, the switching member 2 automatically moves to the locking position, and the sleeve is quickly attached and fixed to the insertion portion 71. Further, when the switching member 2 is rotated to change the relative positions of the 1st housing portion 31 and the 2 nd housing portion 32 in the circumferential direction of the switching member 2 so as not to overlap, unexpected detachment can be prevented. In addition, the elastic member 53 provides a supporting force to the switching member 2, and thus, movement due to unexpected external force can be prevented, and stability can be improved.
Further, the switching member 2 preferably has a shielding portion 24, and the shielding portion 24 is connected to the 2 nd contact portion 22 in the lateral direction. When the 2 nd contact portion 22 contacts the positioning member 51, the shielding portion 24 covers the positioning member 51 in the lateral direction with respect to the axis 11, preventing the positioning member 51 from being touched from the outside, and the positioning member 51 is stably positioned in the fitting portion 13.
For the same reason, the 1 st abutment 21 is connected to the base 23 in the lateral direction (connected in such a manner as to be adjacent in a direction parallel to the axis 11), and covers the 2 nd step 62. An internal space 27 is formed in the 1 st contact portion 21, the base portion 23, and the fitting portion 13. The elastic member 53 is accommodated in the inner space 27. The 1 st abutting portion 21 is not affected by the outside so as to protect the deformation of the elastic member 53.
In addition, the switching member 2 preferably has an anti-slip structure 52 against which the finger 8 is pressed. Further, the outer peripheral wall 25 of the switching member 2 has at least 1 recess 26 provided with the 2 nd housing portion 32, and when the switching member 2 is operated by pressing the recess 26 with the finger portion 8, the contact area between the switching member 2 and the finger portion 8 increases due to the recess 26, so that the stability improves. In the present embodiment, the number of the concave portions 26 is one, and the concave portions 26 are ring grooves. The recess 26 may be at least one.
In addition, two through holes 132 are formed in the fitting portion 13, and the two through holes 132 may be symmetrically arranged around the axis 11 to perform different types of attachment and fixation.
