TECHNICAL FIELD
[0001] The utility model relates to the technical field of bit box, concretely to a bit box. BACKGROUND
[0002] In today's many industrial manufacturing, equipment maintenance and DIY manual work scenes, the bit is a very common tool component, which cooperates with the electric or manual screwdriver to operate various screws to meet different fastening or disassembly needs. With the continuous improvement of operation refinement, the types of bits are increasingly rich, including various types such as cross, straight, internal hexagonal and torx.
[0003] The proper storage and convenient use of bits have always been the key problems that trouble users. The traditional storage mode is to scatter the bits in the tool box or drawer, which causes the bits to be easily disordered and lost. Each time a specific bit is found, a lot of time and energy is wasted in the chaotic space, which greatly reduces the work efficiency, and it is difficult to systematically arrange and classify the bits.
[0004] Although the existing bit boxes on the market try to solve these problems, there are still obvious defects. Many bit boxes are not satisfactory in the connection design of the box cover and the box body. Some use simple buckles or magnetic attraction to connect. In the process of frequent use, the box cover is easy to fall off accidentally, which leads to the loss of the box cover, affects the integrity of the bit box, and the bit is easy to be eroded or lost due to the lack of the box cover. In addition, some bit boxes lack reasonable planning in the opening mode, and cannot accurately limit the opening angle of the box cover. When the opening angle of the box cover is too large, it will occupy too much operation space, which brings inconvenience to the personnel working in a small working area. If the opening angle of the box cover is too small, it will hinder the smooth taking of the bit and affect the operation process.
[0005] In view of the above situation, there is an urgent need for a new type of bit box, which has a unique rotary box cover and box body connection structure, so that the box cover is always connected with the box body during the rotation opening and closing process, effectively avoiding the loss of the box cover. At the same time, it can accurately limit the rotation opening angle of the box cover, which not only guarantees the reasonable use of the operation space, but also facilitates the user to safely and efficiently take the bit, so as to overcome the many deficiencies of the existing bit box in the connection structure and use function, better meet the high standard requirements of modern industry and manual operation for bit storage management.

[0031] The utility model provides a bit box.
[0032] In the embodiment, referring to Figures 1-4 The bit box comprises a bottom shell 1, a plurality of bit slot holes 3 for inserting and placing bits 2 are arranged at the upper side of the bottom shell 1 at intervals, and rotation holes 4 are arranged at the two ends of the bottom shell, an arc-shaped limiting groove 5 is arranged on the outer ring of the rotation hole 4.
[0033] A box cover 6 is arranged on the bottom shell 1, and connecting feet 7 are arranged on the two sides of the box cover 6.
[0034] In the above technical scheme, a plurality of bit slot holes are arranged at the upper side of the bottom shell at intervals according to design requirements, and the size of the bit slot holes needs to be matched with the outer size of common bits so that the bits can be smoothly inserted and stably placed. Rotation holes are made at the two ends of the bottom shell by drilling or other forming processes, and then an arc-shaped limiting groove is processed on the outer ring of the rotation hole.
[0035] The connecting feet are arranged on the two sides of the box cover, and a rotation shaft and a limiting shaft are arranged on the connecting feet. The diameter of the rotation shaft is matched with the inner diameter of the rotation hole of the bottom shell, so that the rotation shaft can be smoothly inserted into the rotation hole and realize rotation cooperation. The diameter and length of the limiting shaft are matched with the arc-shaped limiting groove, so that the limiting shaft can be inserted into the arc-shaped limiting groove and freely move in the groove. When installing, the rotation shaft of the connecting feet of the box cover is inserted into the rotation hole of the bottom shell, so that the box cover can rotate relative to the bottom shell, and the limiting shaft enters the arc-shaped limiting groove, thereby completing the assembly of the bit box.
[0036] The bit slot holes realize the orderly storage of a plurality of bits, so that the bits can be arranged in order and be conveniently classified, managed and taken. The rotating connecting structure makes the box cover and the bottom shell closely connected and conveniently opened and closed, and enhances the integrity and use convenience of the bit box. The cooperation of the arc-shaped limiting groove and the limiting shaft provides guiding and limiting effects for the opening and closing of the box cover, prevents the over-rotation of the box cover, and guarantees the stability and safety of the bit box in the use process.
[0037] Specifically, the arc of the arc-shaped limiting groove is 40-60 degrees.
[0038] In the embodiment, the arc-shaped limiting groove with an arc of 40-60 degrees can reasonably limit the opening angle of the box cover.

[0041] Specifically, the top of the limiting shaft is a semicircular structure.
[0042] In the embodiment, the semicircular structure at the top of the limiting shaft cooperates more smoothly with the arc-shaped limiting groove and the positioning concave surface. During the rotation of the box cover, the semicircular structure can reduce the frictional resistance with the inner wall of the arc-shaped limiting groove, so that the opening and closing of the box cover is more flexible and easy; at the same time, when contacting the positioning concave surface, the semicircular structure can better fit, improve the accuracy and stability of positioning, reduce wear and damage due to structural interference, and prolong the service life of the bit box.
[0043] Specifically, the limiting shaft is in extrusion cooperation with the arc-shaped groove, and the limiting shaft is in clearance cooperation with the positioning concave surface at the two ends of the arc-shaped groove.
[0044] In the embodiment, the extrusion cooperation of the limiting shaft and the arc-shaped groove can enhance the stability of the box cover during rotation, prevent the box cover from shaking or accidentally rotating due to looseness, and ensure the reliability of the bit box during use. The clearance cooperation of the limiting shaft and the positioning concave surface enables the box cover to smoothly embed in the positioning concave surface for positioning when reaching the limit position, which realizes accurate positioning and avoids the jamming phenomenon caused by excessive cooperation, improves the smoothness and accuracy of the opening and closing action of the bit box.
[0045] Specifically, the bit groove hole is arranged in one row or multiple rows along the length direction of the bottom shell.
[0046] In the embodiment, the bit groove holes are arranged in one or more rows along the length direction of the bottom shell, and the accommodation mode can be flexibly adjusted according to different bit quantity and type requirements. One row is suitable for the case of less bit types but more bit quantity, and multiple rows can accommodate more different types of bits, thereby improving the versatility and accommodation capacity of the bit box, facilitating users to classify, arrange and store the bits according to actual use scenarios, and improving the efficiency of bit management. As shown in Figure 1 , the single-row bit box and as shown in Figure 4 , the multi-row bit box.
[0047] Specifically, the bottom shell is provided with a groove hole 11 at the bottom for accommodating the connecting rod 14.
[0048] In the embodiment, the slot at the bottom of the bottom shell provides a convenient way for the connection of the bit box and the connecting rod.
[0049] Specifically, the bottom shell is provided with an inner recessed plane 12 at both sides for connecting the connecting feet, and the rotating hole and the arc-shaped limiting groove are arranged on the inner recessed plane 12.
[0050] In the embodiment, the inner recessed plane at both sides of the bottom shell provides a precise mounting position for the connecting feet of the box cover, so that the connection between the box cover and the bottom shell is more compact and neat.
[0051] Specifically, the depth of the inner recessed plane is equal to the thickness of the connecting feet.
[0052] In the embodiment, the design that the depth of the inner recessed plane is equal to the thickness of the connecting feet can ensure the stability and precision of the connecting feet during rotation, and also improves the overall appearance quality of the bit box.
[0053] Specifically, the box cover is provided with a plurality of hollow holes 13 on the end face away from the bottom shell.
[0054] In the embodiment, the hollow holes can reduce the weight of the box cover, so that the bit box is more portable and easy to operate; in addition, the hollow holes can also increase the aesthetics and recognition of the bit box to some extent, so that it is more distinctive among many tools.
