The bolt end is not guided, and is not easy to install when assembling opponent parts or nuts, so that the assembling efficiency is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model provides an easy to assemble guide bolt, the smooth round platform in surface is adopted to the tip of screw rod, and the structure can provide the direction for adversary's part or nut installation to promote assembly efficiency.
The guide bolt convenient to mount comprises a bolt head and a screw rod, wherein one end of the screw rod is connected with the bolt head, a guide area is arranged at the other end of the screw rod, the guide area is in a circular truncated cone shape and is smooth in surface, the nominal diameter of the screw rod is d, the diameter of the end head of the guide area is d1, and the diameter d1 of the end head of the guide area is 0.5-0.7 times of the nominal diameter d of the screw rod.
The utility model discloses in, the tip of screw rod adopts the glossy round platform in surface, and diameter d1 of direction district end is 0.5 ~ 0.7 times its at the end position for screw rod nominal diameter d, and the structure can provide the direction for adversary's part or nut installation to promote assembly efficiency.
The diameter of the circular truncated cone-shaped guide area along the axial direction of the screw rod is gradually increased, the top surface of the circular truncated cone-shaped guide area is the end of the guide area, the diameter of the circular truncated cone-shaped guide area is d1, and the bottom surface of the circular truncated cone-shaped guide area is connected with the screw rod. The diameter of the circular truncated cone-shaped guide area is gradually increased from the top surface to the bottom surface of the circular truncated cone-shaped guide area.
The length d2 of the guide area is more than or equal to 3 mm. Namely, the height of the circular truncated cone-shaped guide area is 3 mm-10 mm.
The bolt head is provided with a circle of groove surrounding the screw rod, and the groove can be added with a sealing ring to improve the sealing property.
Compared with the prior art, the utility model has the advantages of as follows:
the utility model discloses an easy to assemble guide bolt has solved the prior art problem through less change on current bolt basis, has the advantage that the change volume is little, the effect is obvious, has good economic nature and practicality.
The utility model discloses an extension bolt guiding area length reduces guiding area front end diameter, easily inserts the bolt in the mounting hole that corresponds when making adversary's part installation to improve assembly efficiency.
Drawings
Fig. 1 is the structure schematic diagram of the guide bolt convenient to install.
Detailed Description
The easy-to-install guide bolt of the present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, the guide bolt convenient to mount comprises a bolt head 1 and a screw rod 2, one end of the screw rod 2 is connected with the bolt head 1, the other end of the screw rod 2 is provided with a guide area 3, the guide area 3 is in a circular truncated cone shape and has a smooth surface, the nominal diameter of the screw rod 2 is d, the diameter of the end of the guide area 3 is d1, and the diameter d1 of the end of the guide area 3 is 0.5-0.7 times of the nominal diameter d of the screw rod 2.
The diameter of the circular truncated cone-shaped guide area 3 along the axial direction of the screw rod 2 is gradually increased, the top surface of the circular truncated cone-shaped guide area 3 is the end of the guide area 3, the diameter is d1, and the bottom surface of the circular truncated cone-shaped guide area 3 is connected with the screw rod 2. The diameter of the circular truncated cone-shaped guide area 3 gradually increases from the top surface to the bottom surface of the circular truncated cone-shaped guide area 3.
The length d2 of the guide area 3 is more than or equal to 3 mm. Namely, the height of the truncated cone-shaped guide area 3 is 3 mm-10 mm.
The bolt head 1 is provided with a circle of groove 4 surrounding the screw rod 2, and the groove 4 can be added with a sealing ring to improve the sealing property.
The utility model discloses a bolt has bolt head 1, screw rod 2, guiding area 3. The guide area 3 is smooth and thread-free, and the diameter d1 of the front end of the guide area 3 is 0.5-0.7 times of the nominal diameter d of the bolt. The length d2 of the guide area 3 is more than or equal to 3 mm.
