Drag chain is suitable for use in the occasion of reciprocating motion, can play to built-in cable, oil pipe, tracheae, water pipe etc.
Traction and protective effect, the every section of drag chain can be opened, be easy for installation and maintenance.Low noise when movement, it is wear-resisting, can high-speed motion,
Drag chain has been widely used in numerically-controlled machine tool, electronic equipment, stone machining equipment, glass machinery, door and window machinery, injection molding machine, machine at present
Tool hand, handling equipment, Automatic Warehouse etc..Bridge drag chain is a kind of most common drag chain, and bridge drag chain is mainly by left and right
The carrier bar of two sides and intermediate link block composition, it is low that there are bonding strengths between the carrier bar and link block of existing bridge drag chain,
The problem of being easy to appear carrier bar and link block slippage with runing time, seriously affects drag chain long-time steady operation.
Utility model content
The utility model provides a kind of bridge drag chain, is easy to slip to solve carrier bar and link block of the existing technology
The problem of.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of bridge drag chain is made of, each carrier bar several carrier bars of the left and right sides and several intermediate link blocks
Main body is made of outside boss and inside boss, and a connecting hole, adjacent chain is respectively set in outside boss and inside boss
Plate is connected to each other by connecting column across connecting hole, and two arc fixture blocks and two are respectively set in boss front of and behind on the inside of carrier bar
A fixture block, the subsequent fixture block of carrier bar rotate between the carrier bar front arc fixture block being attached thereto, and set behind boss on the inside of carrier bar
Two inserting columns up and down are set, a card convex is arranged in each inserting column surface, and a slot, link block is respectively set in link block left and right ends
Left and right sides top is respectively set a card slot, and link block left and right ends extend to form a lug forward and backward, in carrier bar
The inserting column of side is connected in the slot of corresponding link block, and the card convex on inserting column is connected in the card slot of link block, connecting column main body
"-" type card slot is arranged in centre setting groove, connecting column rear end, and six prismatic card slots are arranged in the bolumn cap surface of connecting column front end.
Setting slot forms hollow type structure in the middle part of the inserting column that boss is arranged below on the inside of above-mentioned carrier bar.
When the utility model is used, link block and the carrier bar of the left and right sides are connected using snap fit, while adjacent
Carrier bar realizes hinged connection by connecting column, and the subsequent fixture block of carrier bar turns between the carrier bar front arc fixture block being attached thereto
Dynamic, the carrier bar that is connected so again can limit rotation amplitude while being freely rotated, and the lug of link block left and right ends can
It effectively prevent the carrier bar interconnected to slip problem, the effective guarantee operation stability of numerically-controlled machine tool bridge drag chain has and sets
Count ingenious, stable and reliable operation and advantage at low cost.

Specific embodiment
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 and Fig. 8, a kind of bridge drag chain, by the several of the left and right sides
A carrier bar 1 and several intermediate link blocks 2 form, and each 1 main body of carrier bar is made of outside boss and inside boss, and outside is convex
A connecting hole 4 is respectively set in platform and inside boss, and adjacent carrier bar passes through connecting hole 4 by connecting column 3 and be connected to each other, chain
Two arc fixture blocks 5 and two fixture blocks 6 are respectively set in boss front of and behind on the inside of plate, and the subsequent fixture block 6 of carrier bar is in phase therewith
It is rotated between carrier bar front arc fixture block 5 even, setting slot 9 is formed hollow in the middle part of the inserting column that boss is arranged below on the inside of carrier bar
Two inserting columns 7 up and down are arranged on the inside of carrier bar for formula structure behind boss, a card convex 8 is arranged in each 7 surface of inserting column, and link block is left
A slot 11 is respectively set in right both ends, and a card slot 12, link block left and right ends are respectively set in top at left and right sides of link block
