Description

A kind of condom production fixture suit

Technical field

The utility model relates to a kind of condom tool of production, in particular to a kind of condom production fixture suit.

Background technique

The condom tool of production is the tool for production safety set.

Existing condom production fixture as shown in Figure 14, Figure 15, including chain 1, support shaft 31, bearing 32, bracket 2, Rotating block 45, rotating bar 51.

Chain 1 includes alternateing hinged outer chain group and interior chain group, and each interior chain group includes two interior chains disposed in parallel Plate 12, the sleeve 15 for contacting at two inner plates 12 is equipped at the both ends of two inner plates, 12 opposite face, and each outer chain group includes two It is arranged in parallel and is located at the outer plate 11 in 12 outside of inner plate.

Support shaft 31 is vertically fixedly connected on the lateral surface of outer plate 11, and 32 fixing sleeve of bearing is set on support shaft 31.Branch Frame 2 includes being sequentially connected to form the first vertical bar 21 of closed ring, first crossbar 221, the second vertical bar 23, second crossbar 222, First vertical bar 21 and the second vertical bar 23 are parallel to each other, and first crossbar 221 and second crossbar 222 are parallel to each other, the first vertical bar 21 Lateral surface is fixed on the outboard end of support shaft 31 and keeps bracket 2 laterally disposed.It is horizontal between first crossbar 221 and second crossbar 222 To through having hinge bar 41 and consolidate its screw thread in the lateral surface hexagonal socket nut 223 of first crossbar 221 and second crossbar 222 Fixed, rotating block 45 is articulated on hinge bar 41.Rotating bar 51 is vertically arranged on rotating block 45 and rotating bar 51 can circumferentially rotate, The fixture for molded safety set is fixedly mounted again in the outer end of rotating bar 51.

Since the outer wall of hexagonal socket nut 223 is close to the inner wall of perforation, when hinge bar 41 itself does circumferential movement, It will drive hexagonal socket nut 223 and do circumferential movement, this will lead to generate between the outer wall of hexagonal socket nut 223 and perforation inner wall and rub It wipes, over time, will lead to hexagonal socket nut 223 and the gap of perforation becomes larger, and then cause hinge bar 41 can be in two perforation Between generate shaking, easily there is the phenomenon that hinge bar 41 loosens, to influence the normal work of whole production fixture, therefore have improvement Space.

Utility model content

The purpose of the utility model is to provide a kind of condom production fixture suits, have stability high and durable spy Point.

The above-mentioned technical purpose of the utility model has the technical scheme that

A kind of condom production fixture suit, including bracket, hinge bar form the of closed ring including being sequentially connected One vertical bar, first crossbar, the second vertical bar, second crossbar, the first crossbar and second crossbar are parallel to each other and extend transversely through There is perforation, the both ends of the hinge bar are arranged in two perforation respectively, are equipped between the two perforation inner walls and hinge bar outer wall Sliding bearing, described sliding bearing one end are equipped with convex edge and are located at the inboard face of first crossbar and second crossbar.

It using the above scheme, will be outside hinge bar by being equipped with sliding bearing between perforation inner wall and hinge bar outer wall Wall is isolated with perforation inner wall, is avoided hinge bar and is generated bigger friction with perforation inner wall and bracket is caused to damage, plays guarantor Protect the effect of bracket；And the abrasion resistance of sliding bearing is good, and the service life is long, if sliding bearing is ground after prolonged use Damage, can also facilitate replacement sliding bearing, for the replaceable holder that compares, this scheme also saves maintenance cost.

Preferably, condom production fixture suit further includes the rotating block for being articulated with the hinge bar, the rotating block First bearing is embedded on two relative side, two first bearings are sheathed on the hinge bar, the first bearing Lateral surface contact at the convex edge lateral surface.

Using the above scheme, the setting of first bearing is for keeping rotating block more smooth during rotation, by by The side of one bearing contacts at the lateral surface of convex edge, both plays the role of limit to first bearing, in turn avoids rotating block and is turning Friction is generated when dynamic between first crossbar, second crossbar.

Preferably, second vertical bar is located at the lower section of the first crossbar and second crossbar, and in the second vertical bar upper end Face is provided with the supporting table for being used to support the rotating block.

Using the above scheme, by the way that the second vertical bar to be located to the lower section of first crossbar and second crossbar and on the second vertical bar Equipped with supporting table, when rotating block rotation, supporting table can play the role of support to rotating block.

Preferably, running through in the supporting table has centre bore.

Using the above scheme, the setting of centre bore can save the cost of manufacture of supporting table.

Preferably, second vertical bar, which is equipped with, is located at institute with the consistent square groove of its length direction, the supporting table It states in square groove.

Using the above scheme, by the way that supporting table to be fixedly installed in square groove, supporting table can be made stronger.

Preferably, two perforation are located at the junction of the first crossbar, second crossbar and second vertical bar.

Using the above scheme, perforation is located to the junction of first crossbar, second crossbar and the second vertical bar, rotating block can be made Length be set as minimum, save material.

Preferably, condom production fixture suit further includes chain, and the lateral surface of the outer plate of the chain is vertically fixed There is support shaft, support shaft outer end is arranged with bearing and is limited by position-limit mechanism.

Using the above scheme, the advantages of form of the setting of bearing for rolling chain is mobile, rolling is by resistance Small, movement is smooth.

Preferably, the position-limit mechanism includes the limited location snap ring being integrally connected on the support shaft periphery, is located at axis It holds outboard end and is sheathed on the limit annulus of support shaft, be threadedly connected to support shaft outer end face to compress the T-type spiral shell of limit annulus Bolt.

Using the above scheme, by the position-limit mechanism, the dismounting of bearing can be facilitated.

In conclusion the utility model has the following beneficial effects:

By perforation inner wall and hinge bar outer wall between be equipped with sliding bearing, by hinge bar outer wall and perforation inner wall every From avoiding hinge bar and generate bigger friction with perforation inner wall and bracket is caused to damage, play the effect of protective cradle；And And the abrasion resistance of sliding bearing is good, the service life is long, if sliding bearing is worn after prolonged use, can also facilitate replacement Sliding bearing, for the replaceable holder that compares, this scheme also saves maintenance cost.
