Description

TECHNICAL FIELD

[0001] The application relates to the technical field of bolt structures, in particular to a manually driven bolt structure. BACKGROUND

[0002] A bolt is a mechanical standard part, usually composed of a head and a screw rod (a cylinder with external threads), a kind of fastener, which needs to be matched with a nut for fastening and connecting two parts with through holes. This connection form is usually called bolt connection. The head of the bolt has various shapes, the common ones are hexagonal head, round head, square head, countersunk head, etc. Among them, the hexagonal head is the most commonly used, which can provide a larger tightening torque, making the connection more secure. The round head bolt is often used in situations that require countersinking, to avoid the head protruding affecting the appearance or function.

[0003] At present, the head of the bolt includes an outer polygonal structure and an inner polygonal structure to cooperate with a wrench for driving fastening. However, in some special use environments, such as outdoor maintenance of vehicles and mechanical equipment, it is not possible to find a suitable wrench, so the bolt cannot be assembled or disassembled, which has certain influence, such as increasing the maintenance and rescue time and cost. SUMMARY

[0004] In view of the above problems, the application aims to provide a manually driven bolt structure, which increases the radial width of the head by a driving member, that is, increases the operation surface of the head. The increased operation surface can be used for manual rotation operation of the bolt, realizing disassembly and assembly rotation of the bolt, so as to be applied to the case where there is no suitable wrench in special environments.

[0005] In order to achieve the above purpose, the technical scheme adopted by the application is as follows: a manually driven bolt structure, the bolt has a threaded section and a head, characterized in that: a driving member is arranged on the head, the driving member extends radially towards the head and increases the radial width of the head.

[0006] Preferably, the driving member is a driving plate with a width greater than the outer diameter of the head arranged at the head, and the two ends of the driving plate extend to the outside of the head.

[0007] Preferably, the driving plate includes a fixed plate fixedly connected with the head, and sliding plates slidingly connected on both sides of the fixed plate.

[0008] Preferably, the driving member is an assembly arc plate and a disassembly arc plate hingedly arranged at the symmetrical quadrant points of the side wall of the head, and a limiting block is arranged on one side of the head in the driving direction of the assembly arc plate and the disassembly arc plate.

[0009] The beneficial effect of the present application is that the manual driving bolt structure provided by the present application is provided with a driving member on the end head, which extends radially towards the end head and increases the radial width of the end head. By increasing the radial width of the end head through the driving member, the operation surface of the end head is increased, and the manual rotation operation of the bolt can be performed through the increased operation surface, so that the disassembly and assembly rotation of the bolt can be realized, so as to be applied to the case where the bolt does not have a matching wrench in a special environment.

[0023] In order to enable those skilled in the art to better understand the technical solutions of the present application, the technical solutions of the present application will be further described below in combination with the drawings and embodiments.

[0024] Referring to the drawings Figures 1-12 As shown in the drawings, the bolt 1 has a threaded section 11 and a head 12, the head 12 is usually hexagonal and has an inner hexagonal hole structure, and a matching wrench can be used to drive the head 12 and the entire bolt to rotate to perform tightening and disassembly operations. In order to solve the problem of bolt disassembly and assembly operations in special environments without a matching wrench, the present application provides a manually driven bolt structure, which is provided with a driving member on the head 12, the driving member extends radially towards the head 12 and increases the radial width of the head 12. By increasing the radial width of the head 12 through the driving member, the operating surface of the head 12 is increased, and the increased operating surface can be used for manual rotation of the bolt to achieve disassembly and assembly rotation of the bolt, so that it can be applied to special environments without a matching wrench.

[0025] Embodiment 1

[0026] As Figure 2 shown, the driving member is a driving plate 2 provided at the head 12 with a width greater than the outer diameter of the head 12, and the two ends of the driving plate 2 extend to the outside of the head 12. When disassembling the bolt, the rotating external force can be applied by manually holding the driving plate 2 at both sides near the side end, and the driving plate 2 with a width greater than the outer diameter of the head 12 can increase the torque effect of driving the bolt, that is, to achieve labor-saving effect, so that the bolt can be manually disassembled and assembled without a matching wrench.

[0027] In order to solve the interference and blocking effect of the wider driving plate 2, as Figures 3-7 shown, the driving plate 2 includes a fixed plate 21 fixedly connected with the head 12, and sliding plates 22 slidingly connected on both sides of the fixed plate 21. Preferably, the sliding plates 22 on both sides and the fixed plate 21 are in the form of a trapezoidal structure, and are in sliding fit with a key and a key groove. When operating, the sliding plates 22 on both sides are slid outward to form a wider driving plate 2 for rotating the bolt; and after rotating and tightening, the sliding plates 22 on both sides are slid reversely, so that the overall width of the driving plate 2 is adapted to the outer diameter of the head 12, thereby avoiding the interference and blocking effect of the wider driving plate 2.

[0028] Embodiment 2

[0029] As Figures 8-12 shown, the driving member is a disassembly arc plate 32 and an assembly arc plate 31 symmetrically hinged at the quadrant points on the side wall of the head, and a limiting block 13 is arranged on one side of the head 12 in the driving direction of the disassembly arc plate 32 and the assembly arc plate 31. As Figure 11As shown, when the bolt is tightened, the assembly arc plate 31 is rotated open and abuts against the limiting block 13 to limit the rotation of the assembly arc plate 31, then force is applied to the assembly arc plate 31 in the direction of the arrow shown in the figure to tighten the bolt. When disassembling, as shown, the disassembly arc plate 32 is opened and abuts against the limiting block 13, then force is applied to the disassembly arc plate 32 to disassemble the bolt. Figure 12 As shown, when the bolt is tightened, the assembly arc plate 31 is rotated open and abuts against the limiting block 13 to limit the rotation of the assembly arc plate 31, then force is applied to the assembly arc plate 31 in the direction of the arrow shown in the figure to tighten the bolt. When disassembling, as shown, the disassembly arc plate 32 is opened and abuts against the limiting block 13, then force is applied to the disassembly arc plate 32 to disassemble the bolt.

[0030] The principle of the application is that if the bolt structure of Embodiment 1 is used, the sliding plates 22 on both sides are slid outward during operation to form a wider driving plate 2 for rotating the bolt, and after rotation and tightening, the sliding plates 22 on both sides are slid in the opposite direction.

[0031] As shown, when the bolt is tightened, the assembly arc plate 31 is rotated open and abuts against the limiting block 13 to limit the rotation of the assembly arc plate 31, then force is applied to the assembly arc plate 31 in the direction of the arrow shown in the figure to tighten the bolt. When disassembling, as shown, the disassembly arc plate 32 is opened and abuts against the limiting block 13, then force is applied to the disassembly arc plate 32 to disassemble the bolt.

[0032] The basic principles, main features and advantages of the application are shown and described above. Various changes and improvements can be made to the application without departing from the spirit and scope of the application, and these changes and improvements are within the scope of the application.
