Abstract
The utility model discloses a multifunctional screw convenient for dismounting, which comprises a hexagonal nut and a screw rod, wherein a wale circular column is arranged between the hexagonal nut and the screw rod; and the axial directions of the wale circular column and the screw rod are the same, and the surface of the cord circular column is provided with an axial wale. According to the utility model, the wale circular column is added on a screw with the hexagonal nut, the wale circular column is convenient to twist by hand the screw is screwed or unscrewed, the rapid dismounting screw purpose is achieved, and the use is very convenient.
Description
Technical field
The utility model relates to a kind of screw, relates in particular to a kind of easy-to-mount multifunctional bolt.
Background technique
Conventional screw all is comprised of nut and screw rod, and nut has Mutiple Choice, but in the majority with hexagon nut.Because the corner angle of nut periphery is 120 °, and the limited length of nut, if so turn than being easier to allow the algesiogenic sensation of finger with hand, be difficult to use larger power, so conventional screw all screws up with a wrench or unscrews, more convenient when instrument is sufficient, if but do not have special tool temporarily, then be difficult to satisfy user demand.
Summary of the invention
The purpose of this utility model provides a kind of easy-to-mount multifunctional bolt with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
Multifunctional bolt described in the utility model comprises hexagon nut and screw rod, be provided with the burr cylindrical body between described hexagon nut and the described screw rod, described burr cylindrical body is identical with the axial direction of described screw rod, and the cylindrical surface of described burr is provided with the burr of axial direction.
As preferably, the cylindrical diameter of described burr is greater than the diameter of described screw rod and less than the diameter of described hexagon nut; The cylindrical length of described burr is greater than the length of described hexagon nut and less than the length of described screw rod.
Further, the length sum of the cylindrical length of described burr and described hexagon nut is greater than the length of described screw rod; The end face of described hexagon nut is provided with the running-deep-hole with shape and the consistent size of described screw rod, the end face of described hexagon nut also is provided with the shallow counterbore consistent with the cylindrical shape of described burr and diameter, described running-deep-hole and described shallow counterbore concentric are provided with the internal thread corresponding with the burr of described burr periphery on the axial inwall of described running-deep-hole and described shallow counterbore.
Said structure can be realized two cooperation turns between the multifunctional bolt, its process is as follows: the screw rod of first multifunctional bolt inserts in the running-deep-hole of second multifunctional bolt, insert in the shallow counterbore of second multifunctional bolt the cylindrical lower end of the burr of first multifunctional bolt, internal thread in the burr of burr periphery and the shallow counterbore cooperatively interacts, rotate first multifunctional bolt by hand or spanner this moment, and second multifunctional bolt rotated together.
The beneficial effects of the utility model are:
Multifunctional bolt described in the utility model has increased the burr cylindrical body on the basis of the screw with hexagon nut, is convenient to turn the burr cylindrical body with hand, to tighten or to unscrew screw, reaches the purpose of fast assembling-disassembling screw, and is very easy to use; End face at hexagon nut increases and the shape of screw rod and the running-deep-hole of consistent size, and the shallow counterbore consistent with the cylindrical shape of burr and diameter, make and to cooperate simultaneously turn between two multifunctional bolts, solved a screw length out of use problem when inadequate, used convenient.
Description of drawings
Fig. 1 is the main TV structure schematic diagram of multifunctional bolt described in the utility model;
Fig. 2 is the plan structure schematic diagram of multifunctional bolt described in the utility model;
Fig. 3 is that the master that two described multifunctional bolts are used in conjunction with in the utility model looks schematic diagram.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, the utility model comprises hexagon nut 1 and screw rod 3, be provided with burr cylindrical body 2 between hexagon nut 1 and the screw rod 3, burr cylindrical body 2 is identical with the axial direction of screw rod 3, and the surface of burr cylindrical body 2 is provided with the burr of axial direction (unmarked among the figure).The diameter of burr cylindrical body 2 is greater than the diameter of screw rod 3 and less than the diameter of hexagon nut 1; The length of burr cylindrical body 2 is greater than the length of hexagon nut 1 and less than the length of screw rod 3; The length sum of the length of burr cylindrical body 2 and hexagon nut 1 is greater than the length of screw rod 3.
As shown in Figure 2, the end face of hexagon nut 1 is provided with the running-deep-hole 4 with shape and the consistent size of screw rod 3, the end face of hexagon nut 1 also is provided with the shallow counterbore 5 consistent with the shape of burr cylindrical body 2 and diameter, running-deep-hole 4 and shallow counterbore 5 concentrics are provided with the internal thread 6 corresponding with the burr on burr cylindrical body 2 surfaces on the axial inwall of running-deep-hole 4 and shallow counterbore 5.
As depicted in figs. 1 and 2, during use, both available spanner turned hexagon nut 1 to tighten or to unscrew screw, also can turn burr cylindrical body 2 tightening or to unscrew screw with hand, the elasticity that concrete selective basis need to be tightened and on-the-spot instrument and decide.Owing to having increased the selection diversity of instrument, the utility model use is convenient; When required elasticity is less demanding, turn burr cylindrical body 2 to tighten or to unscrew screw with hand, speed is very fast, reaches the purpose of fast assembling-disassembling screw, and is very easy to use.
As shown in Figure 3, cooperation turn between two multifunctional bolts, its process is as follows: the screw rod 3 of first multifunctional bolt (multifunctional bolt above among Fig. 3) inserts in the running-deep-hole of second multifunctional bolt (multifunctional bolt below among Fig. 3), insert in the shallow counterbore of second multifunctional bolt the lower end of the burr cylindrical body 2 of first multifunctional bolt, internal thread in the burr on burr cylindrical body 2 surfaces of first multifunctional bolt and the shallow counterbore cooperatively interacts, rotate first multifunctional bolt by hand or spanner this moment, and second multifunctional bolt rotated together.This situation generally degree of depth for the mounting hole that uses screw is larger, the screw rod 9 of second multifunctional bolt, burr cylindrical body 8 and hexagon nut 7 all are absorbed in the mounting hole, can't directly carry out the turn operation to second multifunctional bolt, so need to realize " lengthening " by first multifunctional bolt, operate with the turn of finishing second multifunctional bolt by first multifunctional bolt of turn.
