Detailed Description

In order that the manner in which the above recited features, objects and advantages of the present utility model are obtained will become readily apparent, a more particular description of the utility model will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. Based on the examples in the embodiments, those skilled in the art can obtain other examples without making any inventive effort, which fall within the scope of the utility model. The experimental methods in the following examples are conventional methods unless otherwise specified, and materials, reagents, etc. used in the following examples are commercially available unless otherwise specified.

Examples:

as shown in fig. 1-3, the utility model provides a combined type stud bolt, which comprises a first bolt body 1, wherein a connecting rod 2 is welded on one side of the first bolt body 1, a disc 3 is welded on one side of the connecting rod 2 away from the first bolt body 1, clamping holes 4 are formed in one side of the first bolt body 1 and at two ends of the connecting rod 2, a screw rod 5 is clamped in an inner cavity of the clamping hole 4, one side of the screw rod 5 sequentially penetrates through the clamping hole 4 and the disc 3 and extends to the outside to be welded with a second bolt body 6, and a first screw cap 7 and a second screw cap 8 are respectively connected on the surface of the screw rod 5 and at two sides of the disc 3 in a threaded manner.

The working principle and the beneficial effect of this structure, this stud comprises first bolt body 1, connecting rod 2, disc 3, draw-in hole 4, lead screw 5, second bolt body 6, first nut 7 and second nut 8 are the main part, when using, the through-hole length that offers according to the fastener junction earlier confirms the stud that needs the length, when adjusting this stud's length, first nut 7 to the first bolt body 1 direction screwing up corresponding, pull second bolt body 6 after accomplishing, second bolt body 6 will draw in the lead screw 5 of draw-in card hole 4 inner chamber one end out, keep away from first bolt body 1 one side pulling to laminating with disc 3 with first nut 7, thereby adjust this stud's length, adjust it to the length that is fit for use, after the length adjustment, twist second nut 8, twist it to laminating with disc 3's opposite side, thereby fix the lead screw 5 that will extend out on disc 3, from this adjusting lead screw to this stud's length, through connecting rod 2, 3, draw-in the second bolt body 6 and the cooperation length of second bolt, thereby the length is adjusted according to the different length of this stud's of the fastener, thereby the practicality is offered.
