Abstract
The utility model discloses a separation-resistant high-strength drag chain which comprises a plurality of unit chain links and cover plates, wherein the cover plates are mounted on the chain links; the unit chain links comprise chain blocks and screws; a shaft joint edge and a hole joint edge are arranged at the two ends of each chain block respectively; the hole joint edges are close to the outer sides, and are used for hitching the shaft joint edges on the inner sides of the other chain blocks; and each screw fixes every two tightly hitched chain blocks. The separation-resistant high-strength drag chain is easy to splice, and is not separated or broken easily.
Description
Technical field
Background technique
Existing drag chain is similar to tank chain outward, is comprised of the plurality of cells chain link, rotates freely between chain link.Height in the drag chain of same train, outer height, pitch are identical.The unit chain link is comprised of left and right carrier bar and upper and lower cover plates, and the every joint of drag chain can be opened, and mounting or dismounting are convenient, can put into drag chain to cable, oil pipe, tracheae etc. after opening cover plate.
There are respectively forming hole and shaping axle in chain link two, existing unit, when two blocks of carrier bars link, wherein the forming hole on one and the shaping axle of another piece are socketed into, lean on the elastic characteristic of plastics itself during installation, carrier bar two ends are strutted, be inserted in rear resilience socket, after cover connects, be stained with the vinyl cover of decoration in the outside of axle in the hope of attractive in appearance.But this link connecting mode is being subjected under External Force Acting, is easy to break away from, and drag chain installation sometimes is bad, or acts frequently, and also can produce to break away from the phenomenon that disconnects, and makes troubles to the user.
Chinese utility model patent, the patent No.: CN202186694U, patent name is: in the patent document of the totally-enclosed drag chain of engineering plastic bridge type, disclose a kind of drag chain, the chain link of being made by some engineering plastics is hinged and forms, and is provided with shut between the chain link that faces mutually.Also there are the following problems to adopt this drag chain: if the drag chain frequent movement easily breaks away from disconnection, use inconvenience thereby caused.
The model utility content
The utility model is intended to overcome above deficiency, provides a kind of splicing easy, is difficult for taking off the disconnected anti-high strength drag chain that takes off.
The technological scheme that the utility model adopts is: a kind of anti-disengaging high strength drag chain, comprise a plurality of unit chain link and cover plate, cover plate is installed on chain link, described unit chain link comprises chain piece and screw, chain piece two ends are made into respectively axle jointing edge and hole jointing edge, wherein in the outer part be the hole jointing edge, be used for entangling the inner shafts jointing edge of another chain piece, two chain pieces that screw will tightly overlap are fixed.
On described chain piece, the axle center of axle jointing edge is that screw thread is poroid.
The utility model is a kind of anti-drags the splicing of high strength drag chain easily, and in the situation that screw and screw do not have destroyedly, the chain piece just is not easy to break away from, and can effectively prevent drag chain fracture and disengaging in use.
Description of drawings
Accompanying drawing 1 is the structural representation of facing of a kind of anti-disengaging high strength drag chain of the utility model;
Accompanying drawing 2 is left TV structure schematic diagram of a kind of anti-disengaging high strength drag chain of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in detail:
Embodiment of the present utility model as shown in drawings, a kind of anti-disengaging high strength drag chain, comprise chain piece 1, screw 2 and cover plate 3, chain piece 1 two ends are manufactured with respectively axle jointing edge 4 and hole jointing edge 5, and wherein in the outer part rear two chain pieces 1 that will tightly overlap with screw 2 of inner shafts jointing edge 4 that are used for entangling another chain piece 1 for hole jointing edge 5 are fixed.Also be equiped with cover plate 3 on chain piece 1.For mounting screw more easily, can match in the axle center of axle jointing edge 4 on chain piece 1, and to be designed to screw thread poroid.The Placement of this anti-disengaging drag chain comprises closed, semi-enclosed connection of being connected with totally enclosed type drag chain medium chain piece.
Claims (2)
1. anti-disengaging high strength drag chain, comprise a plurality of unit chain link and cover plate, cover plate is installed on chain link, it is characterized in that: described unit chain link comprises chain piece and screw, chain piece two ends are made into respectively axle jointing edge and hole jointing edge, wherein in the outer part be the hole jointing edge, be used for entangling the inner shafts jointing edge of another chain piece, two chain pieces that screw will tightly overlap are fixed.
2. a kind of anti-disengaging high strength drag chain according to claim 1 is characterized in that: on described chain piece, the axle center of axle jointing edge is that screw thread is poroid.
