Accompanying drawing explanation
Fig. 1 is the part-structure schematic diagram of restrictor bar in embodiment one;
Fig. 2 is the plan view of restrictor bar link in embodiment one;
Fig. 3 is the plan view of restrictor bar link in embodiment two; And
Fig. 4 is the plan view of restrictor bar link in embodiment three.
Embodiment
Below in conjunction with accompanying drawing 1-4, the utility model is further described:
Embodiment one
As shown in Figure 1, restrictor bar comprises the body of rod 1 of many hollows, and by restrictor bar link 10 that adjacent two bodies of rod 1 link together.The appearance surface cover of the body of rod 1 has crashproof cotton 2.The shape of the body of rod 1 cross section can be circular, Octagon, square and oval etc.
As shown in Figure 2, restrictor bar link 10 comprises link body 11, limited ring 12 and joining portion.
Link body 11 is hollow tube, and shape and the body of rod 1 shape of body adapt, and its size, than the undersized of the body of rod 1, can just insert the inside of the body of rod 1.Limited ring 12 is for being arranged on the annular projection of link body 11 outer surface, and the height of annular projection is equal with the wall thickness of the body of rod 1, when link body 11 inserts the body of rod 1 inside, and the outer surface of limited ring 12 and the flush with outer surface of the body of rod 1.
Limited ring 12 is positioned at the neutral position of link body 11, and link body 11 is divided into symmetrical two sections, joining portion is arranged on two sections of link body 11 symmetrically, for the inwall compact siro spinning technology by the outer wall of link body 11 and the body of rod 1.
Joining portion is the groove or the pit that are arranged on link body 11 outer surface, for storing the glue being coated in link body 11 outer surface.In the present embodiment one, joining portion is specially in the shape of a spiral, extend along the outer surface of link body 11 first deposit glue groove 13.The body of rod 1 is provided with joint on the internal surface corresponding with link body 11, and in the present embodiment one, joint is to be arranged on the body of rod 1 internal surface, can to deposit with first the polished rod section that glue groove 13 glueds joint.
During splicing, only the both sides of link body 11 need be applied glue respectively, insert in two bodies of rod 1, just two bodies of rod 1 can be glued together, install very convenient, and the part such as screw or bolt can not be exposed on the body of rod 1 surface, ensure that the smooth of restrictor bar surface, can not beautiful shape be affected.
Insert in the process of the body of rod 1 at link body 11, because both gaps are very little, the glue being coated in link body 11 top layer is easily scraped, and causes the bonding insecure of this part and the body of rod 1 inwall; But first deposits the glue stored in glue groove 13 can not be scraped, and can ensure firmly bonding.
Embodiment two
As shown in Figure 3, restrictor bar comprises the body of rod of two hollows, and the restrictor bar link 20 linked together by two bodies of rod.Restrictor bar link 20 comprises link body 21, limited ring 22 and joining portion.The body of rod is round bar shape, and link body 21 is hollow circular-tube.Joining portion is the first outside thread 23 being arranged on link body 21 outer surface, and joint is the internal thread being arranged at the body of rod 1 internal surface.
During splicing, only the both sides of link body 21 need be screwed in respectively in two bodies of rod, the internal thread of the first outside thread 23 and body of rod inwall is screwed, just can by two body of rod compact siro spinning technology together, install very convenient, also can not affect the beautiful shape of the restrictor bar spliced.
Embodiment three
As shown in Figure 4, restrictor bar comprises the body of rod of two hollows, and the restrictor bar link 30 linked together by two bodies of rod.Restrictor bar link 30 comprises link body 31, limited ring 32 and joining portion.The body of rod is round bar shape, and link body 31 is hollow circular-tube.Joining portion is the second external thread section 33 arranged respectively at the both sides place of adjacent limited ring 32, and be arranged on other positions, link body 31 surface second deposit glue groove 34.Second external thread section 33 only extends several pitch, and joint is be set in turn in the internal thread segment on the body of rod 1 internal surface, and deposits with second the polished rod section that glue groove 34 glueds joint.
Restrictor bar link 30 can adopt glue to bond simultaneously and screw togather two kinds of modes with thread section and be connected with the body of rod, and fastness is very high.The Placement of the present embodiment three, the mode bonded relative to only using glue, can avoid the aging rear engaging force of glue to decline, improve working life; The mode screwed togather relative to only using thread section, due to without the need to the inwall depths machining internal thread section at the body of rod, is decreased manufacture difficulty, and is matched by longer polished rod position, can improve the concentricity of link body 31 and the body of rod.
The foregoing is only preferred embodiment of the present utility model; not thereby scope of patent protection of the present utility model is limited; joining portion can also be protruding or draw-in groove; joint is the draw-in groove or projection that mate with joining portion; when link body is inserted into restrictor bar body of rod inside; rotate an angle and namely make protruding and draw-in groove engaging, thus be fixedly connected with adjacent restrictor bar.
