Description

Technical Field

[0001] This utility model relates to the field of bolt-related technology, and in particular to a magnetic quick-positioning bolt. Background Technology

[0002] Bolt: A mechanical part, a cylindrical threaded fastener used with a nut. It is a type of fastener consisting of a head and a shank (a cylinder with external threads), which needs to be used with a nut to fasten two parts with through holes.

[0003] Magnetic bolts are fastening devices that use magnetic force to achieve rapid assembly and disassembly. They mainly consist of three parts: a pre-embedded nut, a magnetic inner core, and a magnetic rotating head. Their core working principle is to drive the bolt body to rotate and lock using magnetic force, completing the fastening operation without the need for traditional tools.

[0004] Chinese patent document CN105508386A discloses a magnetic bolt, including a bolt head and a threaded rod integrally formed therewith. The bolt head has a groove in the middle, with an expansion sleeve embedded within the groove, and a permanent magnet installed inside the expansion sleeve. The bolt head also has an ejection channel communicating with the groove, and a rubber plug is installed on the ejection channel. The groove has a regular hexagonal cross-section, and the end face of the permanent magnet has a cross-shaped groove. This patent document allows for quick location of nuts and washers when they fall out.

[0005] The aforementioned patent documents can quickly locate the nut and washer during implementation, but they cannot effectively reduce the positioning resistance of the bolt. This results in excessive friction when the bolt rotates, which increases the bolt's tightening force and affects the bolt's positioning efficiency. Utility Model Content

[0006] The main purpose of this invention is to provide a magnetic quick-positioning bolt, which can effectively solve the problem of not being able to effectively reduce the positioning resistance of the bolt.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A magnetic quick-positioning bolt includes a threaded rod, a bolt assembly fixedly connected to the upper end of the outer surface of the threaded rod, a magnetic component fixedly connected to the lower side of the inner side of the bolt assembly, a limit mechanism fixedly connected to the middle position of the upper side of the inner side of the bolt assembly, a guide mechanism fixedly connected to the lower end of the outer surface of the threaded rod, and a rolling component fixedly connected to the middle of the inner cavity of the threaded rod.

[0009] Preferably, the bolt assembly includes a bolt head, and the upper and lower parts of the outer surface sidewall of the bolt head are chamfered.

[0010] Preferably, the magnetic attraction component includes a countersunk block, on which a permanent magnet is fixedly mounted at the middle of the upper part of the outer surface of the countersunk block, and the lower end of the outer surface of the countersunk block is fixedly connected to the bottom of the inner cavity of the bolt head.

[0011] Preferably, the limiting mechanism includes a fixed plate, a limiting groove is formed in the middle of the upper part of the outer surface of the fixed plate, and the outer surface of the fixed plate is fixedly connected to the upper part of the inner cavity of the bolt head.

[0012] Preferably, the guiding mechanism includes a conical platform, with a guide post fixedly connected to the upper end of the outer surface of the conical platform, and the upper end of the outer surface of the guide post being fixedly connected to the lower end of the outer surface of the threaded rod.

[0013] Preferably, the rolling assembly includes a vertical rod, and a number of sets of limiting rings are fixedly connected to the outer surface of the vertical rod at intervals. The inner cavities of the sets of limiting rings are all arranged in a ring array with a number of balls, and the outer surface of the vertical rod is fixedly connected to the middle of the inner cavity of the threaded rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model uses a bolt assembly to support the magnetic assembly and the limiting mechanism. The magnetic assembly facilitates the magnetic attraction of the threaded rod to the head of the screwdriver, while the limiting mechanism facilitates the screwdriver's rotation and tightening of the threaded rod, improving the practicality of the device. The guiding mechanism facilitates the insertion of the lower part of the threaded rod into the required installation hole, and the rolling assembly reduces the frictional resistance of the threaded rod as it rotates into the installation hole, further enhancing the practicality and versatility of the device.

[0016] 2. When the threaded rod is rotated and installed, the conical platform and guide post of this utility model allow the threaded rod to slide smoothly into the hole. At the same time, when the threaded rod is inserted into the hole, several sets of balls can convert the sliding friction between the outer surface of the threaded rod and the hole into rolling friction, thereby reducing the positioning resistance and improving the practicality and universality of the device.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1 As shown, a magnetic quick-positioning bolt includes a threaded rod 1. A bolt assembly 2 is fixedly connected to the upper end of the outer surface of the threaded rod 1, which can bear the load of the magnetic assembly 3 and the limiting mechanism 4. The magnetic assembly 3 is fixedly connected to the lower side of the inner side of the bolt assembly 2, which can facilitate the magnetic attraction of the threaded rod 1 to the head of a screwdriver. The limiting mechanism 4 is fixedly connected to the middle position of the upper side of the inner side of the bolt assembly 2, which can facilitate the screwdriver to rotate and tighten the threaded rod 1. The guide mechanism 5 is fixedly connected to the lower end of the outer surface of the threaded rod 1, which can facilitate the insertion of the lower part of the threaded rod 1 into the required installation hole. A rolling assembly 6 is fixedly connected to the middle of the inner cavity of the threaded rod 1, which can reduce the frictional resistance of the threaded rod 1 rotating into the installation hole.

[0024] To achieve the purpose of supporting the magnetic suction component 3 and the limiting mechanism 4, please refer to... Figure 2 The bolt assembly 2 includes a bolt head 21. The upper and lower parts of the outer surface sidewall of the bolt head 21 are chamfered 22, which can facilitate the bolt head 21 to slide into the upper part of the mounting hole.

[0025] To facilitate the magnetic attachment of the threaded rod 1 to the screwdriver head, see [reference needed]. Figure 2 The magnetic component 3 includes a countersunk block 31, which can make the center of gravity of the bolt head 21 face downward and stable. A permanent magnet 32 ​​is installed and fixed in the middle of the upper part of the outer surface of the countersunk block 31, which can make the bolt head 21 adhere to the screwdriver head when the screw rod head is close to the inner cavity of the limiting groove 42. The lower end of the outer surface of the countersunk block 31 is fixedly connected to the bottom of the inner cavity of the bolt head 21.

[0026] To facilitate the screwdriver's rotation and tightening of the threaded rod 1, please refer to... Figure 2 The limiting mechanism 4 includes a fixed plate 41. A limiting groove 42 is formed in the middle of the upper part of the outer surface of the fixed plate 41, and the outer surface of the fixed plate 41 is fixedly connected to the upper part of the inner cavity of the bolt head 21.

[0027] To facilitate the insertion of the lower part of the threaded rod 1 into the desired installation hole, refer to... Figure 3 The guide mechanism 5 includes a conical platform 51, and a guide post 52 is fixedly connected to the upper end of the outer surface of the conical platform 51. This allows the threaded rod 1 to automatically slide into the hole, reducing the need for manual position adjustment. The upper end of the outer surface of the guide post 52 is fixedly connected to the lower end of the outer surface of the threaded rod 1.

[0028] To reduce the frictional resistance of the threaded rod 1 rotating into the mounting hole, refer to... Figure 4 The rolling assembly 6 includes a vertical rod 61, and several sets of limiting rings 62 are fixedly connected to the outer surface of the vertical rod 61 at intervals. This can reduce the positioning resistance when the threaded rod 1 is rotated into the hole, so that the threaded rod 1 can be installed in the hole more quickly. Several sets of limiting rings 62 are all arranged in a ring array with several balls 63 inside the cavity, and the outer surface of the vertical rod 61 is fixedly connected to the middle of the inner cavity of the threaded rod 1.

[0029] The working principle of this utility model is as follows: First, the conical platform 51 and the guide post 52 are aligned with the hole to be installed. At this time, the conical angle on the surface of the guide post 52 allows the threaded rod 1 to slide smoothly into the hole. Then, the hex wrench is used to clamp the threaded rod 1 into the hole. Alternatively, the threaded rod 1 can be clamped into the inner cavity of the limiting groove 42 by inserting a corresponding screwdriver. During this process, the bolt head 21 will automatically be attracted to the screwdriver head by the magnetic attraction of the permanent magnet 32, which makes it easier for the screwdriver to rotate and tighten the threaded rod 1 into the installation hole. At this time, the positioning resistance of the threaded rod 1 when it rotates into the bottom of the hole is greatly reduced by several sets of ball bearings 63.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
