The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0026] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0027] like Figure 1-2As shown, a screw 100 provided by one embodiment of the present invention comprises a main body 10, a lug 20 and a sliding member 40, wherein the lug 20 is mounted on the main body 10, and the sliding member 40 is mounted on the lug 20. The main body 10 is used for threaded connection with an object to be connected, the lug 20 is provided with a first structure, and the sliding member 40 is provided with a second structure, the first structure is matched and connected with the second structure, and the first structure and the second structure can move relative to each other, so that the sliding member 40 can reciprocate between a first position and a second position relative to the lug 20, and the sliding member 40 can rotate from the second position to a third position relative to the lug, and the sliding member 40 does not abut against the lug 20 during the rotation process.

[0028] The main body 10 has a screw portion 11 and a nut portion 12, and the screw portion 11 is used for threaded connection with the object to be connected. One end of the screw portion 11 is connected to the first end face of the nut portion 12, and the second end face of the nut portion 12 is connected to the lug 20, and the first end face of the nut portion 12 and the second end face of the nut portion 12 are opposite end faces. It should be understood that the periphery of the screw portion 11 can be partially threaded or completely threaded, that is, the threaded section of the screw portion 11 can be adjusted as needed to meet different usage scenarios.

[0029] In this way, through the above structure, when the main body 10 needs to be screwed, the sliding member 40 can be rotated to the third position, and the user can directly screw the sliding member 40 by hand to drive the screw portion 11 to rotate, thereby tightening or loosening the screw 100 without the aid of tools such as a screwdriver, which is more convenient to use.

[0030] In some embodiments, the first structure is a connecting arm 30, and the second structure is a sliding hole 411, and the connecting arm 30 can slide from a first position to a second position in the sliding hole 411. The connecting arm 30 is a rod-shaped object with a certain length, and its shape can be a round shaft as a whole, or a combination of multiple shapes, for example, a combination of a partial rectangular block and a partial round shaft.

[0031] The specific structure of the screw 100 when the first structure is the connecting arm 30 and the second structure is the sliding hole 411 will be described in detail below:

[0032] In some embodiments, the lug 20 is provided with a through hole 21, one end of the connecting arm 30 is inserted into the through hole 21, and the other end of the connecting arm 30 is installed with the sliding member 40, that is, the connecting arm 30 passes through the sliding hole 411 of the sliding member 40, and the sliding member 40 is sleeved on the connecting arm 30 and does not disengage. Among them, the sliding hole 411 is a long hole with a certain length, so that the connecting arm 30 has a sliding space in the sliding hole 411, and the sliding member 40 and the connecting arm 30 can slide relative to each other. In this way, the connecting arm 30 is fixed to the lug 20 and does not move. Pulling the sliding member 40 can make the sliding member 40 slide from the first position to the second position relative to the nut portion 12. Moreover, the sliding member 40 can rotate around the connecting arm 30 from the second position to the third position, and the sliding member 40 does not abut against the lug 20. It should be understood that the second position refers to the position where the inner wall of the sliding hole 411 abuts against the connecting arm 30 and the sliding member 40 can rotate around the connecting arm 30, and the first position refers to the position where the sliding member 40 is before it moves to the second position. The third position refers to the position where the center line of the sliding member 40 is perpendicular or approximately perpendicular to the nut portion 12. It should be noted that when the center line of the sliding member 40 is perpendicular to the nut portion 12, the torque for turning the screw 11 is the largest.

[0033] Through the above structure, when the screw 11 needs to be screwed, the sliding member 40 only needs to be rotated to the third position relative to the nut portion 12. At this time, the sliding member 40 is erected relative to the nut portion 12, and the user can directly grasp the sliding member 40 by hand to rotate it, thereby driving the screw portion 11 to rotate. The screw 100 can be tightened or loosened without the aid of a screwdriver, which is more convenient to use.

[0034] It should be understood that the connection between the lug 20 and the nut portion 12 can be achieved by welding, die-casting or cutting, or by plugging, that is, one of the lug 20 or the nut portion 12 is provided with a protrusion (not marked), and the other is provided with a groove (not marked). Figure 3 The shape of the groove matches the shape of the protrusion, and the protrusion is inserted into the groove to achieve the connection between the lug 20 and the nut portion 12. In this embodiment, the lug 20 and the nut portion 12 are integrally formed, and the shape of one side of the lug 20 is approximately the same as the periphery of the nut portion 12.

[0035] In some embodiments, the lug 20 and the connecting arm 30 can be fixed together by welding, and in this case, the lug 20 does not need to be provided with the through hole 21. During installation, the connecting arm 30 can be inserted into the sliding hole 411 first, and then the end of the connecting arm 30 and the lug 20 are fixed by welding, so as to complete the installation of the sliding member 40.

[0036] Please refer again Figure 2 In some embodiments, the sliding member 40 includes a sliding portion 41, the sliding portion 41 is provided with a sliding hole 411, the sliding hole 411 passes through opposite ends of the sliding portion 41, and the sliding portion 41 is sleeved on the connecting arm 30 through the sliding hole 411. In this embodiment, the sliding hole 411 is in the shape of a waist-shaped hole, and along the direction perpendicular to the central axis of the connecting arm 30, the distance between the two opposite inner walls of the waist-shaped hole is greater than the diameter of the connecting arm 30. Of course, the shape of the sliding hole 411 can also be other shapes, such as a rectangular shape.

[0037] Further, when the connecting arm 30 is at the center position of the nut portion 12, the central axis of the connecting arm 30 passes through the geometric center of the nut portion 12, and the sliding portion 41 is partially located at one side end of the connecting arm 30, and the sliding portion 41 is partially located at the other side end of the connecting arm 30. Therefore, when the sliding portion 41 moves to the second position through the sliding hole 411 and rotates to the third position, compared with the sliding portion 41 not moving from the first position to the second position but directly rotating around the connecting arm 30, the overall length of the sliding portion 41 can obtain more growth space. In this way, when the sliding portion 41 rotates to the third position, the distance between the end of the sliding portion away from the nut portion 12 and the end face of the nut portion 12 is larger, that is, the torque for twisting the screw 11 is the largest, and when the resistance required to overcome the rotation of the screw portion 11 is certain, the force required to be applied by the user is smaller, that is, the screw portion 11 can be twisted with more effort, which is more convenient to use.

[0038] Please combine Figure 2 , Figure 4-5 In some embodiments, in order to enable children, girls or the elderly who have less strength to use the screw 100 and do not want to twist it directly with their hands, the sliding member 40 also includes a head 42, one end of the head 42 is connected to the sliding portion 41, and the other end of the head 42 is recessed in the direction close to the sliding hole 411 to form a knife groove 421. It can be understood that the knife groove is used for inserting tools such as screwdrivers to twist the screw portion 11, and the scope of use is wider and more convenient. It should be understood that the shape of the knife groove 421 can be a straight line shape, a cross shape, and of course other shapes, such as plum blossom shape or hexagonal shape.

[0039] Furthermore, the sliding member 40 further includes a shoulder portion 43, which is formed by the side end of the head portion 42 extending in a direction away from the sliding hole 411. When the shoulder portion 43 abuts against the lug 20, the sliding member 41 is reset to the first position. It can be understood that after the user tightens or loosens the screw 100, the sliding member 40 can be rotated around the connecting arm 30 until the sliding portion 41 is parallel to the nut portion 12. At this time, the sliding member 40 is in the second position, and then the head 42 is pushed toward the connecting arm 30 until the shoulder portion 43 abuts against the lug 20. At this time, it indicates that the sliding member 40 is reset to the first position. The sliding member 40 can be received in the receiving groove formed by the lug 20 and the second end surface of the nut portion 12, which effectively reduces the volume of the screw while realizing tool-free assembly and removal of the screw.

[0040] In some embodiments, the sliding member 40 is provided with anti-skid stripes 401, and the anti-skid stripes 401 are used to increase the roughness of the surface of the sliding member 40 to prevent the user from slipping when twisting the sliding member 40. In this embodiment, the anti-skid stripes 401 are arranged on both end surfaces of the head 42. It should be understood that the shape of the anti-skid stripes 401 can be wavy stripes, or stripes of other shapes, such as Z-shaped stripes. In this embodiment, the shape of the anti-skid stripes 401 is wavy stripes. In addition to increasing the surface roughness of the end surface of the head 42, the wavy anti-skid stripes 410 can also make the sweat or water droplets on the user's fingers slide down into the concave part of the wavy stripes, thereby preventing the user's fingers and the head 42 from slipping when twisting. In some other embodiments, the sliding part 41 is also provided with the anti-skid stripes 401.

[0041] In some embodiments, the outer contour of the head 42 is set to be an arc shape to prevent the user from slipping and cutting the user's fingers when the screw is turned. In this embodiment, the block formed by the connection between the head 42 and the sliding part 41 is in the shape of a mushroom. When the sliding member 40 is reset to the first position, the outer contour of the head 42 coincides with the edge of the nut part 12, making the screw 100 regular and beautiful as a whole.

[0042] In some embodiments, the number of the lugs 20 is two, namely, a first lug 23 and a second lug 24. The first lug 23 and the second lug 24 are symmetrically arranged on the second end surface of the nut portion 12. One end of the connecting arm 30 is inserted into the first lug 23, and the other end of the connecting arm 30 is inserted into the second lug 24. In this embodiment, the center line of the connecting arm 30 is on the straight line where the diameter of the nut portion 12 is located, so the sliding member 40 can rotate around the connecting arm 30 at an angle greater than 0° and less than 180°. In this way, the first lug 23 and the second lug 24 jointly restrict the connecting arm 30 from moving, so that the screw 100 can be more stable during use. Of course, if there is only one lug 20, one end of the connecting arm 30 is inserted into the through hole 21, and the other end of the connecting arm 30 is bolted with a sliding member 40, and the size of the other end of the connecting arm 30 is slightly larger than the diameter of the sliding hole 411 to prevent the sliding member 40 from detaching from the connecting arm 30.

[0043] The screw 100 provided in the embodiment of the present invention can be connected by the cooperation of the first structure and the second structure, and the relative movement between the first structure and the second structure, so that the sliding member 40 can move from the first position to the second position relative to the nut portion 12, and the sliding member 40 can be rotated from the second position to the third position relative to the nut portion 12, so that the user can directly grasp the sliding member 40 by hand to rotate to achieve tightening or loosening of the screw, and the screw can be manually tightened without the aid of a screwdriver, which is more convenient to use.

[0044] Please combine Figure 6-7 A screw 100' provided in another embodiment of the present invention also has the main body 10, the lug 20 and the sliding member 40 in the above embodiment. The difference between the screw 100' and the above embodiment lies in that the first structure is a sliding hole 411', and the second structure is a connecting arm 30', that is, the lug 20 is provided with the sliding hole 411', and the sliding member 40 is provided with the connecting arm 30'. The sliding member 40 can drive the connecting arm 30' to slide from the first position to the second position in the sliding hole 411', and the sliding member 40 can rotate from the second position to the third position relative to the nut portion 12 and the sliding member 40 does not abut against the lug 20.

[0045] The shape of the sliding hole 411' of the lug 20 is different from that of the sliding hole 411 in the above embodiment. The sliding hole 411' consists of two parts: a long square hole 4111' and a round hole 4112'. The square hole 4111' is connected to the round hole 4112'. The square hole 4111' has a long side and a short side, the long side is longer than the short side, and the diameter of the round hole 4112' is larger than the size of the short side. In this embodiment, the first position refers to the position of the connecting arm 30' when it is at one end of the square hole 4111' away from the round hole 4112', and the second position refers to the position of the connecting arm 30' when it is in the round hole 4112'.

[0046] The connecting arm 30' includes a first end, a second end and a middle section, the two ends of the middle section are respectively connected to the first end and the second end, the first end and the second end are both parts inserted into the sliding hole 411', the first end and the second end need to be rectangular, and the shapes of the first end and the second end are both adapted to the shape of the square hole 4111', and the long side of the first end needs to be larger than the short side of the square hole 4111'. In this way, when the connecting arm 30' is rotated 90° or approximately 90° relative to the lug 20, the long sides of the first end and the second end are both in contact with the short side of the square hole 4111', so that the screw part 11 can be driven to rotate when the sliding member 40 is twisted.

[0047] When the screw 100' needs to be tightened or loosened, the sliding member 40 only needs to be moved to drive the connecting arm 30' to move from the first position to the second position, and then the sliding member 40 is rotated around the central axis of the connecting arm 30' until the long side of the first end or the second end of the connecting arm 30' abuts against the short side of the square hole 4111', that is, the sliding member 40 drives the connecting arm 30' to rotate about 90°. At this time, the sliding member 40 is in an upright state relative to the nut portion 12, and the user can directly loosen or tighten the screw 100 by twisting the sliding member 40 by hand.

[0048] The above description is only an implementation mode of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
