Description

[Technical field]

[0001] The present invention relates to a socket holding frame assembly, and more particularly to a socket holding frame assembly having a socket positioning holder whose position and orientation can be adjusted to extend its service life. [Background technology]

[0002] A conventional socket holding frame assembly includes a track base and a plurality of socket positioning holders for mounting sockets. Each socket positioning holder is fixed onto the track base via a self-tapping screw so that the socket positioning holder does not rotate or slide relative to the track base.

[0003] The socket positioning holder is made of plastic and has a pilot hole formed at its bottom. When a self-tapping screw is driven into the pilot hole and screwed into it, the self-tapping screw forms a thread on the outer periphery of the pilot hole. Thus, a threaded engagement is achieved between the self-tapping screw and the socket positioning holder. The socket positioning holder is fixed to the track base by tightening the self-tapping screw.

[0004] However, the self-tapping screw is frequently loosened and tightened to adjust the position and orientation of the socket positioning holder. Therefore, the thread formed on the outer periphery of the pilot hole is easily worn and deformed. Therefore, when the conventional socket holding frame is used for a long period of time, the gap between the screw formed on the outer periphery of the pilot hole and the self-tapping screw becomes large. Therefore, the self-tapping screw easily falls off and becomes loose. Therefore, the socket positioning holder cannot be firmly and stably fixed to the track base.

[0005] In addition, if the self-tapping screw is tightened too much, the pilot hole of the socket positioning holder is easily damaged, and if damaged, the socket positioning holder needs to be replaced. Therefore, it becomes impossible to connect the self-tapping screw to the socket positioning holder. [Prior art documents] [Patent documents]

[0012] 1 to 4, a socket holding frame assembly according to the present invention is comprised of a track base 10 and a plurality of socket positioning holders 20. As shown in FIG.

[0013] 1 to 4 and 6, the track base 10 has an elongated shape and is made of metal. The track base 10 has an elongated base panel 11 and a connection hole 14. The connection hole 14 is elongated and extends along the longitudinal direction of the base panel 11, and is formed penetrating the base panel 11. The two ends of the connection hole 14 are closed ends and are spaced apart from the two ends of the base panel 11, respectively. In some embodiments, the connection hole 14 may be replaced by a plurality of elongated holes arranged in a line along the base panel 11 and spaced apart from each other.

[0014] The truck base 10 may be an elongated truck having an H-shaped cross section, and is composed of two side panels 13 respectively connected to two sides of the base panel 11. The two side panels 13 extend upward from the base panel 11 to define an upper channel 12 between the top of the base panel 11 and the two side panels 13. The two side panels 13 extend downward from the base panel 11 to define a lower channel 16 between the bottom of the base panel 11 and the two side panels 13. The lower channel 16 communicates with the upper channel 12 through a connecting hole 14. Referring to FIG. 4, two tabs may be formed respectively at the bottoms of the two side panels 13 and extend toward each other. A bottom opening is formed at the bottom of the truck base 10 and is disposed between the two tabs, and communicates with the lower channel 16 accordingly.

[0015] 2, 3, 6, and 8, a plurality of socket positioning holders 20 are arranged along the longitudinal direction of the track base 10 and slidably and rotatably connected to the track base 10. Each socket positioning holder 20 is composed of a holder body 21, an insertion portion 23, and a bolt 25. The holder body 21 is made of a resin material, rotatably, slidably, and detachably connected to the track base 10, and arranged above the base panel 11. The holder body 21 includes a holder base 211 and a holding portion 215. The holder base 211 may have a circular outer edge and is slidably and rotatably arranged in the upper channel 12 of the track base 10. The holding portion 215 is formed on the upper surface of the holder base 211, protrudes from the upper surface, and is adapted to engage and connect with the socket 50. Thus, the socket 50 can be set in the track base 10 via the socket positioning holder 20.

[0016] 2 to 6, inserted portion 23 is made of metal, is inserted into and coupled to the bottom of holder body 21, and is provided with a screw hole 232 at a predetermined position corresponding to connection hole 14 of track base 10 for communication. Bolt 25 is inserted from lower channel 16 through connection hole 14 into the bottom of base panel 11 and is connected to screw hole 232 of inserted portion 23 via screw engagement, thereby firmly fixing holder body 21 to track base 10.

[0017] The holder body 21 includes an inserting portion 213 formed at the bottom of the holder body 21. The inserted portion 23 is inserted into the inserting portion 213 of the holder body 21 and assembled therewith. The bottom surface of the inserting portion 213 and the bottom surface of the inserted portion 23 are located higher than the bottom surface of the holder base 211. When the bottom surface of the holder base 211 contacts the upper surface of the base panel 11, a gap is formed between the upper surface of the base panel 11 and the bottom surface of the inserting portion 213, thereby preventing the bottom surface of the inserted portion 23 from directly contacting the upper surface of the base panel 11. The inserted portion 23 may be integrally joined to the holder body 21 by insert molding. The inserted portion 23 may also be inserted into the inserting portion 213 of the holder body 21 and integrated therewith by ultrasonic insertion or thermal crimping.

[0018] 4 to 7, screw hole 232 is formed penetrating inserted portion 23. Inserted portion 23 is arranged on the outer periphery of inserted portion 23 and includes a plurality of engagement recesses 234 that engage with holder body 21. The plurality of engagement recesses 234 are arranged diagonally or parallel to the axis of screw hole 232 of inserted portion 23. Insertion portion 213 of holder body 21 engages with the plurality of engagement recesses 234 arranged around inserted portion 23, and can promote engagement between inserted portion 23 and holder body 21.

[0019] Preferably, the inserted portion 23 includes a first tooth-shaped portion 235, a second tooth-shaped portion 237 located above the first tooth-shaped portion 235, and an annular groove 236 formed between the first tooth-shaped portion 235 and the second tooth-shaped portion 237. The annular groove 236 engages with the holder body 21. The multiple engagement recesses 234 arranged around the first tooth-shaped portion 235 and the multiple engagement recesses 234 arranged around the second tooth-shaped portion 237 engage with the holder body 21. The multiple engagement recesses 234 arranged around the first tooth-shaped portion 235 and the multiple engagement recesses 234 arranged around the second tooth-shaped portion 237 are inclined in opposite directions with respect to the axis of the screw hole 232, respectively. That is, the multiple engagement recesses 234 arranged around the first tooth-like portion 235 of each inserted portion 23 of the multiple socket positioning holders 20 and the multiple engagement recesses 234 arranged around the second tooth-like portion 237 of the inserted portion 23 are inclined clockwise and counterclockwise, respectively. In this manner, the annular groove 236 and the respective engagement recesses 234 arranged around the first tooth-like portion 235 and the second tooth-like portion 237 are arranged to be inclined in opposite directions, thereby further strengthening the engagement between the inserted portion 23 and the holder body 21. As a result, when the inserted portion 23 is pulled downward, the inserted portion 23 and the holder body 21 are less likely to come off from each other.

[0020] 2 to 4 and 6, the bolt 25 includes a rod 253 and a head 251 formed at an end of the rod 253. The rod 253 is inserted through the connection hole 14 of the track base 10 from below the base panel 11, and is connected to the screw hole 232 of the inserted portion 23 via threaded engagement between the bolt 25 and the holder body 21. The head 251 is disposed below the base panel 11. Preferably, each socket positioning holder 20 is made of a resin material and includes a washer 27 disposed between the head 251 of the bolt 25 and the base panel 11.

[0021] 2, 8-10, the holder body 21 of the socket positioning holder 20 is inserted into the upper channel 12 of the track base 10 from the top or end of the track base 10. The sockets 50 are placed on the holding parts 215 of the holder body 21. Each socket 50 can be rotated so that the dimension marks of the sockets 50 face the same direction. Then, the holder body 21 is fixed onto the track base 10. The bolts 25 are inserted through the connection holes 14 of the base panel 11 from the underside of the base panel 11 and screwed into the screw holes 232 of the inserted parts 23 combined with the holder body 21. Therefore, the socket positioning holder 20 having the sockets 50 can be reliably held at a desired position and in a desired orientation. Therefore, the user can clearly recognize the dimensions of the sockets 50 and can easily select the sockets 50 to be used.

[0022] Each socket positioning holder 20 is firmly fixed to the track base 10 through threaded engagement between the bolt 25 and the insertion part 23 combined with the bottom of the holder body 21 to fix the position and orientation of the holder body 21 relative to the track base 10. Even if an external force acts on the socket holding frame assembly of the present invention, the position and orientation of each socket positioning holder 20 with the corresponding socket 50 will not be changed inadvertently. Therefore, the socket holding frame assembly of the present invention is stable and convenient to use. To change the position or orientation of each socket positioning holder 20 and the socket 50 thereon, the bolt 25 of the socket positioning holder 20 can be slightly released and the holder body 21 of the socket positioning holder 20 can be moved or rotated relative to the track base 10. After the holder body 21 is moved to a desired position or to a desired orientation, the bolt 25 is tightened again. As a result, the position and orientation of each socket positioning holder 20 can be conveniently adjusted. Since the connection hole 14 is elongated, after slightly releasing the bolt 25, the socket positioning holder 20 can be moved along the connection hole 14 to adjust the spacing between them. Then, the bolt 25 of the socket positioning holder 20 is tightened again.

[0023] Referring to Figures 3 and 11, after connecting the bolt 25 to the screw hole 232 of the inserted portion 23 combined with the bottom of the holder body 21, the user can hold the holder body 21 and rotate the holder body 21 having the inserted portion 23 relative to the bolt 25 to release or fix the socket positioning holder 20.

[0024] Each socket positioning holder 20 is constructed by combining a metal inserted portion 23 with the bottom of the holder body 21, and the bolt 25 is connected to the screw hole 232 of the inserted portion 23 via screw engagement. Therefore, even if the bolt 25 is repeatedly fastened and unfastened, the threads of the screw hole 232 of the inserted portion 23 hardly wear out and are not easily deformed. Therefore, the service life of each socket positioning holder 20 is extended, and the socket positioning holder 20 can be reliably fixed to the track base 10. Even after a long period of use, the socket positioning holder 20 can be stably and firmly fixed to the track base 10. Even if an excessive torque is applied to the bolt 25, the inserted portion 23 will not easily break.

[0025] 12 and 13, in the second embodiment, the track base 10A includes a plurality of connection holes 14A arranged in a row along the track base 10A. Each connection hole 14A is a circular through hole formed penetrating the base panel 11. Therefore, when the holder body 21 is moved to align the screw hole 232 of the inserted portion 23 with any of the connection holes 14A, the bolt 25 can be inserted from the connection hole 14A and screwed into the screw hole 232 of the inserted portion 23 to fix the position of the holder body 21. In addition, when the bolt 25 is detached from the holder body 21 of the socket positioning holder 20, the position and orientation of the holder body 21 can also be adjusted.

[0026] 14 and 15, in the third embodiment, the inserted portion 23B of each socket positioning holder 20B has a polygonal edge. The inserted portion 23B is inserted into and surrounded by the insert portion 213B of the holder body 21B. The insert portion 213B is located below the insert portion 23B and includes an insert bottom flange portion 2131 that covers the lower surface of the insert portion 23B.

[0027] With this arrangement, each socket positioning holder 20 can be rotated with respect to the track base 10 to adjust its orientation, and can be slid relatively to the track base 10 to adjust its position. The socket positioning holder 20 can be firmly and stably fixed to the track base 10 to fix its position and orientation through threaded engagement between the bolt 25 assembled to the bottom of the holder body 21 and the inserted part 23. Since the inserted part 23 is made of metal, the thread formed in the screw hole 232 of the inserted part 23 hardly wears and does not easily deform, and the space between the screw hole 232 and the bolt 25 can be maintained, and the bolt 25 and the screw hole 232 of the inserted part 23 can be maintained in a firmly coupled state. Even if an excessive torque is applied to the bolt 25, the inserted part 23 will not break or be damaged. Even after a long period of use, the socket positioning holder 20 can be firmly and stably fixed to the track base 10.
