Abstract
The utility model discloses a connection and installation device for chains, which comprises two steel bars arranged separately and vertically. A pair of through holes is correspondingly disposed on the two steel bars, wherein one of the two through holes is an internal threaded hole. The two steel bars are connected through a bolt which is assembled inside the two through holes. The connection and installation device for chains is simple in structure, capable of achieving single-person operation, convenient and fast in use, small in occupied space, capable of being used in narrow maintenance space and suitable for fast installing movable fasteners of row chains.
Description
Technical field
The utility model relates to a kind of chain tipping device.
Background technique
The elongation because new chain weares and teares as yet when more renewing chain; Pitch and total length are shorter than the old chain bar; Cause chain jointing distance bigger, the loose joint button can not be inserted smoothly, difficulty comparatively when new chain is installed; Often need dwindle the interface spacing new chain is installed, waste time and energy through unclamping means such as motor base or the moving motor of dish.
The model utility content
The purpose of the utility model provides a kind of simple in structure, can realize the one man operation, easy to use, quick, take up an area of little, the chain tipping device of also employable quick mounting row chain loose joint button when service clearance is narrow.
For realizing above-mentioned purpose; The utility model adopts following technological scheme: a kind of chain tipping device, comprise that vertical spacing is provided with two steel bars, and correspondence is provided with a pair of through hole on two steel bars; One of them through hole is an interior threaded hole, connects through a bolt that is assemblied in the two through hole between two steel bars.
The correspondence of position up and down of two steel bars is provided with two pairs of through holes, connects through upper and lower two bolts between two steel bars, and two through holes that one of them steel bar is provided with up and down are interior threaded hole.
Said steel bar is a bar shape, and width is between the 7mm-9mm.
The described chain tipping of the utility model device inserts the chain slit with two steel bars with one of two steel bar with the bolt connection earlier again, screws in the second bolt then, and two bolts of screwing dwindle the chain interface gaps is convenient to the installation that loose joint is buckled.The utility model can be realized the one man operation; Easy to use, quick, take up an area of little, and structural design simple, practical, be convenient to promote, when service clearance is narrow, also can use; Especially advantage is more obvious when the special position chain is installed, and can be used for the quick mounting of chain loose joint button.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
By a kind of chain tipping device shown in Figure 1, comprise that it is bar shape that vertical spacing is provided with steel bar 7,6, two steel bars 7,6 that two carbon steels make, width can be any number between the 7mm-9mm, can be 8.97mm such as width.Mutual correspondence is provided with two pairs of through holes 2,4 on two steel bars 7,6; It is the top that a pair of through hole 2,4 lays respectively at two steel bars 7,6; Another lays respectively at the bottom of two steel bars 7,6 to through hole 2,4; The two through hole 2 that is provided with up and down on the steel bar 7 is interior threaded hole, and the two through hole 4 that is provided with up and down on another steel bar 6 is the level and smooth plain bore of inwall.Two steel bars 7, connect through two bolts 3 that laterally arrange up and down between 6, two bolts 3 are assemblied in respectively in two pairs of through holes 2,4.Because the two pairs of through holes 2,4 lay respectively at the top and the bottom of two steel bars 7,6, so between the also corresponding top and bottom that lays respectively at two steel bars 7,6 of two bolts 3.
During use; Earlier 7,6 one of two steel bars are connected with bolt 3; Again the other end of two steel bars 7,6 is inserted respectively in the slit of two pitch chain bars of chain 1 interface both sides; Screw in second bolt, 3, two bolts 3 then and lay respectively at the above and below of chain 1, the both sides bolt 3 of screwing dwindles chain 1 interface gaps and is convenient to the installation that loose joint is buckled up and down.
Claims (3)
1. a chain is hinged with device, and it is characterized in that: comprise that vertical spacing is provided with two steel bars, correspondence is provided with a pair of through hole on two steel bars, and one of them through hole is an interior threaded hole, connects through a bolt that is assemblied in the two through hole between two steel bars.
2. chain tipping device as claimed in claim 1, it is characterized in that: the correspondence of position up and down of two steel bars is provided with two pairs of through holes, connects through upper and lower two bolts between two steel bars, and two through holes that one of them steel bar is provided with up and down are interior threaded hole.
3. according to claim 1 or claim 2 chain tipping device, it is characterized in that: said steel bar is a bar shape, width is between the 7mm-9mm.
