Embodiment
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
As shown in Figure 1 to Figure 3, the fixing rod of the present embodiment comprises: fixing rod body 10, rotation prevention portion 20 and blocked part 30.Wherein fixing rod body 10 has first end and the second end, and the first end of fixing rod body 10 is provided with outside thread, and rotation prevention portion 20 is arranged on externally threaded one end away from fixing rod body 10, and blocked part 30 is arranged on one end away from fixing rod body 10 of rotation prevention portion 20.
When applying the fixing rod of the present embodiment, at the first end of fixing rod body 10, rotation prevention portion 20 and blocked part 30 are set, rotation prevention portion 20 is arranged on externally threaded one end away from fixing rod body 10, and blocked part 30 is arranged on one end away from fixing rod body 10 of rotation prevention portion 20.When being arranged on by fixing rod on fixed plate 40, backstop action is played in blocked part 30, and the axial motion of restriction fixing rod, prevents fixing rod from passing from fixed plate 40.When fixing rod is spacing on fixed plate 40 or when being disassembled by nut 50 by nut 50, rotation prevention portion 20 limits fixing rod and rotates, and then makes the operation of fastening nut 50 only need a spanner just can complete.Make disassembly process more simple, install more quick, easy to use, operate more laborsaving.
In the present embodiment, the major part on fixing rod body 10 is polished rod, and for adjustment fixing plate 40 upper-lower height, the outside thread of the first end of fixing rod body 10 coordinates with nut 50.
In the present embodiment, rotation prevention portion 20 has spline tangent plane 21.Spline tangent plane 21 is utilized to realize spline, easy to process, easily realize.In the present embodiment, spline tangent plane 21 is two of being oppositely arranged.The restriction effect of two spline tangent planes 21 is better.
In the present embodiment, blocked part 30 has the backstop projection 31 protruding from spline tangent plane 21.Backstop projection 31 limits the axial motion of fixing rod, prevents fixing rod from passing from fixed plate 40.Backstop projection 31 structure is simple, easily processes.Preferably, fixing rod body 10, rotation prevention portion 20 and blocked part 30 are integrative-structures, and structure is simple, easy to process.As shown in Figure 3, rotation prevention portion 20 is disposed adjacent with blocked part 30, rotation prevention portion 20 and blocked part 30 are obtained by cylindrical-shaped structure, axially make tangent plane from one end of cylindrical-shaped structure along it and form spline tangent plane 21, radially make tangent plane from the middle part of cylindrical-shaped structure crossing with spline tangent plane 21, this radial section defines the upper surface of backstop projection 31.
Present invention also provides a kind of location adjusting device, as shown in Figure 4 and Figure 5, according to the fixing rod that the embodiment of the location adjusting device of the application comprises fixed plate 40 and is arranged on fixed plate 40, fixing rod is above-mentioned fixing rod.
Arrange rotation prevention portion 20 and blocked part 30 at the first end of fixing rod body 10, rotation prevention portion 20 is arranged on externally threaded one end away from fixing rod body 10, and blocked part 30 is arranged on one end away from fixing rod body 10 of rotation prevention portion 20.When being arranged on by fixing rod on fixed plate 40, backstop action is played in blocked part 30, and the axial motion of restriction fixing rod, prevents fixing rod from passing from fixed plate 40.When fixing rod is spacing on fixed plate 40 or when being disassembled by nut 50 by nut 50, rotation prevention portion 20 limits fixing rod and rotates, and then makes the operation of fastening nut 50 only need a spanner just can complete.Make disassembly process more simple, install more quick, easy to use, operate more laborsaving.
As shown in Figure 6, in the present embodiment, fixed plate 40 is provided with multiple elongated hole 41 be parallel to each other, is provided with the limited part that coordinates with the rotation prevention portion 20 of fixing rod in elongated hole 41 to limit the rotation of fixing rod.Fixing rod body 10 can move along the length direction of elongated hole 41 in elongated hole 41, fixing rod body 10 can be made to rest on arbitrary position in elongated hole 41, achieve the micro-positioning regulators of fixing rod in elongated hole 41.Fixing rod can be made like this in elongated hole 41 to carry out rapid positioning operation.The rotation prevention portion 20 of fixing rod coordinates with the limited part of elongated hole 41, can limit fixing rod and rotate, and makes operator more convenient, more laborsaving when operating.
In the present embodiment, as shown in Figures 3 and 4, the rotation prevention portion 20 of fixing rod has two spline tangent planes 21, and limited part is the hole wall coordinated with two spline tangent planes 21.The cooperation of spline tangent plane 21 and hole wall is utilized to realize spline, easy to process, easily realize.One skilled in the art will appreciate that spline tangent plane also can be one.Certainly, the structure of rotation prevention portion is not limited to be spline tangent plane, in other embodiments, also can be spline projection or spline groove, as long as can realize the spline of fixing rod.Correspondingly, limited part is the structure suitable with rotation prevention portion.
In the present embodiment, the two ends of each elongated hole 41 are equipped with the dismounting hole 411 that the blocked part 30 of fixing rod can be made to pass through.When needing to regulate the position of fixing rod namely to need to change to other positions, hole, fixed disassembly bar is convenient in dismounting hole 411.During dismounting, fixing rod can take out by dismounting hole 411 place that only fixing rod body 10 need be moved to one end of elongated hole 41 from dismounting hole 411.During installation, by the blocked part 30 of fixing rod through dismounting hole 411, fixing rod body 10 is moved in elongated hole 41.Dismantle and operate fairly simple in installation process, position, hole can be changed fast.Certainly, also only dismounting hole can be set in one end of each elongated hole.
As shown in Figs. 7-9, in the present embodiment, location adjusting device also comprises the nut 50 coordinated with the outside thread of fixing rod, and nut 50 comprises nut body 51 and handle 52, and handle 52 is connected on the sidewall of nut body 51.Nut 50 can move up and down along the axial direction of fixing rod and is arranged on fixed plate 40 by fixing rod.Nut 50 can for conventional nut, and preferably, nut 50 is hexagon nut.Handle 52 can easy-to-operat person adjusting nut body 51, uses more convenient.Preferably, handle 52 is welded on the sidewall of nut body 51.Or the connection of handle and nut body also can for rivet.
The specific operation mode of above-mentioned location adjusting device is as follows:
When needing the position regulating fixing rod in elongated hole 41, after only needing slight rotatable handle 52 to be unlocked by fixing rod, fixing rod body 10 can be rested on the arbitrary position in elongated hole 41, realizing fixing rod and carry out quick position in elongated hole 41.When certainly needing the position, hole changing elongated hole 41, during dismounting fixing rod, make fixing rod body 10 move to one end of elongated hole 41 after only needing rotatable handle 52 to be unlocked by fixing rod, fixing rod is taken out from dismounting hole 411.When fixing rod is installed, only needs the blocked part 30 of fixing rod through dismounting hole 411, fixing rod body 10 is moved in elongated hole 41, then fastening nut 50.
In the present embodiment, handle 52 is in bent.The use of easy-to-operat person, saves regulating time, reduces the labor intensity of operator.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
