Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of spare parts, and specifically relates to a double -end bolt. BACKGROUND

[0002] Double -end bolt, also called double -end screw or double -end stud. For connecting the fixed link function of machinery, double -end bolt both ends have threads, the middle screw rod, has thick also has thin, according to need, there is a little double -end stud middle position will set screw head to facilitate operation, the size of the existing double -end bolt usually only has several fixed styles, if temporarily need special size double -end bolt need to be specially processed and produced, it is not convenient enough. CONTENT OF THE UTILITY MODEL

[0003] In view of the above, in order to overcome the defects of the prior art, the utility model provides a double -end bolt that can be freely assembled according to needs.

[0004] In order to achieve the above object, the utility model provides the following technical scheme: a double -end bolt, including hexagon bolt and drive block, the hexagon bolt and the drive block are equipped with two, two drive blocks are pasted into hexagon, the center of two drive blocks after pasting is equipped with the connecting hole that is adapted with the screw rod portion of the hexagon bolt, the side of two drive blocks faces each other and is equipped with the connecting groove that is adapted with the bolt head of the hexagon bolt, the length of the connecting groove is adapted with the thickness of the bolt head of the hexagon bolt twice, and the connecting groove and the bolt head of two hexagon bolts are in interference fit.

[0005] So set, when need special size double -end bolt can take the existing hexagon bolt that meets the single side size, hexagon bolt is complete, and it is easy to meet the single side requirement, then the bolt head of two hexagon bolts can be pasted, the bolt head after pasting is inserted into the connecting groove of drive block and is clamped, then another drive block is covered and is knocked into, when two hexagon bolts are completely knocked in, they will be connected together, and form a double -end bolt that meets the demand size, and two drive blocks will be pasted and constitute the bolt head of double -end bolt, facilitate driving, and the drive block is not easy to come out after being connected due to interference fit, and the bolt itself will not be subjected to radial force, and the connecting structure is stable, and the screw rod of hexagon bolt will be located in the connecting hole, and will not resist the influence of connection.

[0006] Further, the connecting groove is arranged in parallel between the inner side and the outer side of the drive block.

[0007] Thus, the hexagonal bolt is inserted from the corner position when being knocked in, so that the insertion process is smoother, the knocking in is facilitated, and the two sides are wrapped more stably after being knocked in. Another driving block can be knocked in by using a tool with a groove to fit the top corner, so as to avoid damaging the outer wall when knocking.

[0008] Further, the abutting surfaces of the two driving blocks are buckled.

[0009] Thus, the buckled structure is adopted to connect the two more stably and not easily separated.

[0010] Further, one side of the abutting surface of the driving block is provided with a buckling claw facing the connecting hole, and the other side of the abutting surface of the driving block is provided with a claw groove matched with the buckling claw.

[0011] Thus, the two driving blocks can be set in the same shape, and are reversely set to be clamped. After clamping, the buckling claws on the two sides are respectively clamped into the corresponding claw grooves.

[0012] Further, the edge lines on both sides of the opening of the connecting groove in the length direction are chamfered.

[0013] Thus, the two sides are more smooth when being inserted after chamfering the edge lines, and the other two sides do not need to be chamfered because the hexagonal bolts are inserted from the corner position.

[0014] Further, a gasket is further included, which is located between the bolt heads of the two hexagonal bolts, and the diameter of the gasket is smaller than the bolt head of the hexagonal bolt.

[0015] Thus, when the length of the connecting groove is greater than the thickness of the bolt head of the two hexagonal bolts due to machining error, a gasket can be inserted between the two to increase the thickness, so that the adaptability is stronger. The gasket can be made of various materials such as metal and rubber.

[0016] Further, a connecting sleeve is further included, wherein the diameter of one of the hexagonal bolts is smaller than the other hexagonal bolt, the connecting sleeve is sleeved outside the connecting head of the hexagonal bolt with smaller diameter, and the outer wall of the connecting sleeve is arranged in the same way as the bolt head of the hexagonal bolt with larger diameter.

[0017] Thus, the double-headed bolt can be made into a variable-diameter double-headed bolt, and the two heads adopt different bolt sizes. The bolt head of the smaller diameter can be placed together with the bolt head of the other hexagonal bolt in the connecting groove after being sleeved with the connecting sleeve, so that the bolt head is not loose, and the applicability is more extensive.

[0018] Further, the connecting sleeve is provided with a baffle plate on the side facing the hexagonal bolt with small diameter, and the stud of the hexagonal bolt with small diameter is arranged through the baffle plate.

[0019] In this way, the baffle plate can cover the bolt head of the hexagonal bolt with small diameter, so that the bolt head is prevented from falling out due to the size of the bolt head being smaller than the connecting hole, and the connection is more stable. BRIEF DESCRIPTION OF DRAWINGS
