Description

Technical Field

[0001] The invention relates to a hardware tool box, more specifically, to a screwdriver packaging box. Background Art

[0002] A screwdriver bit usually refers to the screwdriver head that is installed on a hand electric drill, electric hammer, or detachable screwdriver to tighten screws. Usually, when people buy a screwdriver with a detachable bit, they will be given several bits of different specifications, and the bit and the handle that installs it are installed in the packaging box for fixation.

[0003] At present, people usually open recessed holes on the packaging box to accommodate the bit and the handle. However, when the recessed hole is used to limit the bit, the handle part of the bit is clamped, and the bit body is usually exposed. Once the clamping force is large, it will be more difficult for people to pull out the bit. When the clamping force is small, the bit cannot be effectively limited, and the bit is easy to fall out of the recessed hole, which makes people confused when taking out the bit and people's user experience is poor.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Summary of the invention

[0005] In view of the deficiencies in the prior art, the object of the present invention is to provide a screwdriver packaging box, which is convenient for installing the screwdriver bit and has a stable installation, so that people can easily take the screwdriver bit.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: a screwdriver packaging box, comprising a mounting seat and a circular ring-shaped limit ring fixedly connected to the top surface of the mounting seat, a notch is provided on the outer peripheral wall of the limit ring to separate it, the top surface of the mounting seat is rotatably connected to a limit assembly located in the limit ring and coaxially arranged with the limit ring, the limit assembly is used to accommodate a screwdriver bit, and a blocking assembly is provided between the limit assembly and the mounting seat to limit its circumferential rotation relative to the mounting seat.

[0007] By adopting the above technical solution, when people need to place a bit, they only need to put the limit assembly into the position of the bit corresponding to the notch, and then put the bit into it manually, and limit the bit through the limit assembly, and then people only need to apply a circumferential rotational force to the limit assembly, so that the force overcomes the restriction of the blocking assembly on the rotation of the limit assembly, so that the limit assembly can rotate, so that the limit ring blocks the position where the limit assembly is placed in the bit, thereby making it impossible for the bit to be taken out, and the bit cannot fall out and scatter due to shaking the mounting base. When people need to take out the bit, they only need to rotate the limit assembly in the opposite direction to the position where the bit is placed in the notch to easily take out the bit.

[0008] The present invention is further configured as follows: when the artificial circumferential force acting on the limit assembly is greater than the circumferential resistance of the blocking point, the blocking point of the blocking assembly eliminates the restriction on the limit assembly; when the single rotation angle of the limit assembly is 360° / number of blocking points, the limit assembly is restricted by the blocking point.

[0009] The present invention is further configured as follows: the blocking assembly includes a plurality of blocking members arranged on the top surface of the mounting seat, the blocking members always have a force acting toward the bottom surface of the limiting assembly, and the bottom surface of the limiting assembly is provided with a plurality of positioning holes engaged with the blocking members.

[0010] By adopting the above technical solution, when the limiting assembly is limited by the blocking assembly, the blocking member can be embedded in the positioning hole under the action of the force toward the bottom surface of the limiting assembly, so that the positioning hole and the blocking member cooperate with each other to limit the circumferential rotation of the limiting assembly.

[0011] The present invention is further configured as follows: the limit assembly includes a connecting piece and an upper baffle and a lower baffle fixedly connected to the upper and lower ends thereof; the upper baffle is provided with a plurality of openings connecting the outside world with the interior of the limit assembly; the number of the openings is half the number of blocking points between the blocking assembly and the limit assembly; the spacing between the upper baffle and the lower baffle is equal to the length of the handle of the bit; and a plurality of the positioning holes are provided on the bottom surface of the lower baffle.

[0012] The present invention is further configured as follows: a plurality of spring plates with lower ends inclined toward the central axis are connected to the inner circumferential wall of the limiting ring, the spring plates are located between the upper baffle plate and the lower baffle plate, and there is elastic deformation capability between the spring plates and the inner circumferential wall of the limiting ring.

[0013] By adopting the above technical solution and arranging the spring sheet, a better limiting effect can be achieved on the lower baffle, and it is convenient for people to install the limiting component, thereby improving people's work efficiency.

[0014] The present invention is further configured such that: a force acting toward the top surface of the lower baffle exists in the gap between the spring piece and the inner peripheral wall of the limiting ring.

[0015] By adopting the above technical solution and providing a force applied to the top surface of the lower baffle, the lower baffle will not collide with the lower end of the spring when people invert the packaging box.

[0016] The present invention is further configured such that: there is a gap between the elastic sheet and the lower blocking sheet.

[0017] By adopting the above technical solution, since there is a gap between the spring piece and the lower baffle, the lower baffle can rotate more smoothly.

[0018] The present invention is further configured as follows: the groove width of the through opening is smaller than the groove width of the notch, the notch is used to accommodate the handle of the bit, and the through opening is used to accommodate the body of the bit.

[0019] By adopting the above technical solution, since the groove width of the through opening is smaller than the groove width of the notch, the notch is used to accommodate the handle of the bit and the through opening is used to accommodate the body of the bit. Therefore, when the bit is placed in the limiting assembly, the body of the bit can be limited by the through opening and is unlikely to shake, thereby preventing the bit from falling into the limiting assembly or from escaping from the limiting assembly.

[0020] In summary, the present invention has the following beneficial effects:

[0021] When people need to place a bit, they only need to put the limit assembly into the position of the bit corresponding to the notch, and then manually put the bit into it, and limit the bit through the limit assembly, and then they only need to apply a circumferential rotational force to the limit assembly, so that the force overcomes the restriction of the blocking assembly on the rotation of the limit assembly, so that the limit assembly can rotate, so that the limit ring blocks the position where the limit assembly is placed in the bit, thereby making it impossible for the bit to be taken out, and the bit cannot fall out and scatter due to shaking the mounting base. When people need to take out the bit, they only need to rotate the limit assembly in the opposite direction until the position where the bit is placed corresponds to the notch, and the bit can be easily taken out.

DETAILED DESCRIPTION

[0034] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0035] Example:

[0036] like Figure 5 and 6 As shown, a screwdriver packaging box includes a cylindrical mounting base 1 with a closed top surface and a circular ring 12 integrally formed on the top surface of the mounting base 1. The outer diameter of the limiting ring 12 is smaller than the outer diameter of the mounting base 1. A notch 121 is provided on the outer peripheral wall of the limiting ring 12 to separate it. The notch 121 is used to accommodate the handle of the screwdriver bit.

[0037] like Figure 1 As shown, a cylindrical cover body 2 with a closed top surface is embedded on the outer side of the limiting ring 12 .

[0038] like Figure 8 and 10 As shown, a circular hole is formed at the center of the top surface of the mounting seat 1, and a positioning cylinder 11 is integrally formed in the circular hole. The height of the positioning cylinder 11 is equal to the sum of the heights of the mounting seat 1 and the limiting ring 12, and the bottom surface of the positioning cylinder 11 is closed. At the same time, a hexagonal prism-shaped positioning pin 111 for clamping the screw handle is integrally formed on its inner bottom surface.

[0039] And if Fig.10As shown, four arc-shaped conducting grooves 14- are provided on the inner top surface of the mounting seat 1, and the four arc-shaped conducting grooves 14- are distributed in a circular array along the central axis of the mounting seat 1, and the outer diameter of the arc-shaped conducting groove 14- is located between the inner diameter and the outer diameter of the limiting ring 12, and an arc-shaped conducting groove 14-2 is provided on the inner peripheral wall of the limiting ring 12 and is connected to the arc-shaped conducting groove 14-1, and the outer diameter of the arc-shaped conducting groove 14-2 is the same as the outer diameter of the arc-shaped conducting groove 14-1.

[0040] like Figure 7 and 11 As shown, the inner wall of the limiting ring 12 is integrally formed with a plurality of spring pieces 13 with their lower ends tilted toward the central axis thereof, the arc length of the spring pieces 13 is less than or equal to the arc length of the second arc-shaped conducting groove 14, and the elastic lower end shields the second arc-shaped conducting groove 14.

[0041] like Figure 2 As shown, the top surface of the mounting seat 1 is rotatably connected to a limit assembly 3 located in and coaxially arranged within the limit ring 12. The limit assembly 3 includes a connecting member which is a connecting tube 33 and an upper baffle 31 and a lower baffle 34 integrally formed at its upper and lower ends.

[0042] like Figure 3 and 4 As shown, the connecting tube 33 is sleeved on the outside of the positioning tube 11, and the lower baffle 34 is located between the top surface of the mounting seat 1 and the lower end of the spring sheet 13. There is a gap between the top surface of the lower baffle 34 and the lower end of the spring sheet 13. The upper baffle 31 is provided with a plurality of through openings 32 connecting the outside with the inside of the limiting assembly 3. The groove width of the through openings 32 is smaller than the groove width of the notch 121. The through openings 32 are used to accommodate the body of the screwdriver. There are 12 through openings 32. The spacing between the upper baffle 31 and the lower baffle 34 is equal to the length of the handle of the screwdriver. The bottom surface of the lower baffle is provided with 24 hemispherical positioning holes 35, and the positioning holes 35 are distributed in a circular array around the central axis of the lower baffle 34.

[0043] There is a blocking component between the limit component 3 and the mounting seat 1 to limit its circumferential rotation relative to the mounting seat 1. When the artificial circumferential force acting on the limit component 3 is greater than the circumferential resistance of the blocking point, the blocking point of the blocking component eliminates the restriction on the limit component 3. When the single rotation angle of the limit component 3 is 360° / number of blocking points, the limit component 3 is restricted by the blocking point.

[0044] like Figure 5 , 8As shown in Figure 9, four recessed holes 15 are provided on the bottom surface of the mounting seat 1, and the four recessed holes 15 are distributed in a circular array with the central axis of the mounting seat 1. The minimum distance from the center of the recessed hole 15 to the central axis of the mounting seat 1 is equal to the minimum axis from the center of the positioning hole 35 to the central axis of the lower baffle 34. The blocking assembly includes a plurality of blocking members which are first marbles 17. The bottom surface of the recessed hole 15 is embedded with a first elastic member 16 located below the first marble 17. The first elastic member 16 is a spring, and the length of the first elastic member 16 is greater than the depth of the recessed hole 15.

[0045] like Fig.11 As shown, the top surface of the limit ring 12 is provided with a downwardly recessed groove 122, the recessed groove 122 is used to accommodate the screw head of the bolt 124, the bottom surface of the recessed groove 122 is provided with a through hole 123 that penetrates into the second arc-shaped conducting groove 14, the inner circumferential wall of the through hole 123 is provided with an internal thread, the internal thread of the through hole 123 is connected to the screw portion of the bolt 124, the lower end of the screw portion of the bolt 124 is embedded with a second elastic member 125 arranged vertically downward, the second elastic member 125 is also a spring, and there is a second marble 126 below the second elastic member 125 that is in point contact with the top surface of the lower baffle 34, and the length of the second elastic member 125 is greater than the distance from the bolt 124 to the second marble 126.

[0046] When people need to assemble the packaging box, they can first align the connecting tube 33 of the limiting assembly 3 with the positioning tube 11 above the mounting seat 1, and then apply a certain downward force to overcome the friction between the inner wall of the connecting tube 33 and the outer wall of the positioning tube 11 to descend.

[0047] And when the outer peripheral wall of the lower baffle 34 contacts the outer wall of the lower end of the spring piece 13, people further apply a greater force so that the force applied to the limit assembly 3 can be transmitted to the spring piece 13, so that the spring piece 13 can rotate relative to the limit ring 12, thereby causing elastic deformation, so that the lower baffle 34 can be smoothly displaced downward, so that it can enter between the spring piece 13 and the top surface of the mounting seat 1.

[0048] Then people put the second marble 126 and the second elastic member 125 into the through hole 123, so that the second elastic member 125 is pressed on the second marble 126, and a guide groove connected to the through hole 123 is opened on the inner wall of the arc guide groove 2. The second marble 126 and the second elastic member 125 are limited by the guide groove. Finally, a bolt 124 is connected to the through hole 123 through an internal thread. The bottom surface of the screw of the bolt 124 presses the second elastic member 125, causing the second elastic member 125 to undergo elastic deformation to apply a downward force to the second marble 126, and the second marble 126 transmits the force to the top surface of the lower baffle 34, so that the entire limiting assembly 3 is stably placed on the mounting seat 1.

[0049] Then people rotate the limit assembly 3 to adjust the angle of the limit assembly 3 through relative rotation of the connecting tube 33 and the positioning tube 11. When the through opening 32 is connected to the notch 121, people can put the screwdriver bit into the limit assembly 3, the handle of the screwdriver bit is located in the limit assembly 3, and the body of the screwdriver bit is located in the through opening 32 and is arranged upward through the through opening 32.

[0050] Then people rotate the limit assembly 3 again, so that it rotates 15°, and the positioning hole 35 on the bottom surface of the lower baffle 34 is circumferentially squeezed with the first marble 17 on the mounting seat 1. Under the decomposition of the force of the first marble 17, the first marble 17 squeezes the first elastic member 16, causing it to undergo elastic deformation, and then the first marble 17 returns to the recessed hole 15. The first elastic member 16 releases elastic potential energy at any time, causing the first marble 17 to conflict with the bottom surface of the lower baffle 34. When the positioning hole 35 after rotating 15° corresponds to the recessed hole 15, the first elastic member 16 pushes the first marble 17 into the positioning hole 35 to continue to have a certain circumferential limiting effect on the lower baffle 34.

[0051] In this state, the through opening 32 equipped with the bit is blocked by the limit ring 12, so that the bit cannot be taken out in all directions, which has a better installation effect on the bit, and the bit will not fall off when the position of the packaging box changes or shakes, and the through opening 32 equipped with the bit can be connected with the notch 121 by only rotating 15°, and people only need to slide the bit out, which is convenient for taking out and effortless.

[0052] When people need to install the next screwdriver bit, they only need to further rotate the limit assembly 3 by 15° in the original rotation direction to align the next opening 32 with the notch 121, and then complete the assembly of the next screwdriver bit through the same operation as above, so that the body of the screwdriver bit is limited in the opening 32 and the handle of the screwdriver bit is located in the limit assembly 3.

[0053] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
