Description
Technical field
the utility model relates to fastener technical field, is a kind of polymer-injecting pump gland for packing box fastener.
Background technology
traditional polymer-injecting pump gland for packing box has six gap on its lower surface, carry out fastening with special gland force-multiplier tool, and the inner side of special gland force-multiplier tool only has an afterburning post, with special gland force-multiplier tool when fastening or dismounting polymer-injecting pump gland for packing box, due to narrow space between fluid end and power end, long-term use easily causes the gap abrasion deformation on polymer-injecting pump gland for packing box lower surface, the special easy slippage of gland force-multiplier tool, affect the fastening of polymer-injecting pump gland for packing box or dismounting, even cause normally keeping in repair.
Summary of the invention
the utility model provides a kind of polymer-injecting pump gland for packing box fastener, overcome the deficiency of above-mentioned prior art, it can effectively solve the existing special easy slippage of gland force-multiplier tool, affects the fastening of polymer-injecting pump gland for packing box or dismounting, even causes the problem that cannot normally keep in repair.
the technical solution of the utility model realizes by following measures: a kind of polymer-injecting pump gland for packing box fastener, comprises clip and boosting-rod; Clip is arc-shaped clamp, be fixed with the afterburning post of at least two at the clear width of clip, the inner face of afterburning post is all positioned on same periphery, has the boosting-rod installing hole of at least one in the outside of clip, and the left end of boosting-rod is fixedly mounted in boosting-rod installing hole.
the further optimization and/or improvements to above-mentioned utility model technical scheme below:
the above-mentioned clear width at clip is fixed with three afterburning posts, and the inner face of three afterburning posts is all positioned on same periphery.
the above-mentioned boosting-rod installing hole that is separated with three between the outside of clip.
above-mentioned clip is semicircle clip.
the above-mentioned outside at boosting-rod is installed with antiskid glue sleeve.
on the inwall of above-mentioned boosting-rod installing hole, have internal thread, have external screw thread in the left end outside of boosting-rod, the left end of boosting-rod is fixedly mounted in boosting-rod installing hole by screw thread.
reasonable and compact in structure of the present utility model, easy to use, by being used in conjunction with of clip and boosting-rod, the object of installation or removal polymer-injecting pump gland for packing box is convenient in realization, have afterburning post on clip be difficult for slippage, stressed evenly, polymer-injecting pump gland for packing box is difficult for the feature of abrasion deformation when installation or removal, reduce production cost, improved maintenance efficiency.
Accompanying drawing explanation
the master that accompanying drawing 1 is the utility model most preferred embodiment looks perspective structure schematic diagram.
coding in accompanying drawing is respectively: 1 is clip, and 2 is boosting-rod, and 3 is afterburning post, and 4 is boosting-rod installing hole, and 5 is antiskid glue sleeve.
The specific embodiment
the utility model is not subject to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
in the utility model, for convenience of description, the description of the relative position relation of each parts is to be all described according to the Butut mode of Figure of description 1, as: the position relationship of forward and backward, upper and lower, left and right etc. is to determine according to the Butut direction of Figure of description 1.
below in conjunction with embodiment and accompanying drawing, the utility model is further described:
as shown in Figure 1, this polymer-injecting pump gland for packing box fastener comprises clip 1 and boosting-rod 2; Clip 1 is arc-shaped clamp, be fixed with the afterburning post 3 of at least two at the clear width of clip 1, the inner face of afterburning post 3 is all positioned on same periphery, has the boosting-rod installing hole 4 of at least one in the outside of clip 1, and the left end of boosting-rod 2 is fixedly mounted in boosting-rod installing hole 4.Like this, the afterburning post 3 on clip 1 is convenient to the more fastening opening position on polymer-injecting pump gland for packing box that is stuck in, and is difficult for slippage, stressed more even; Boosting-rod 2 is convenient to the application of force.
can according to actual needs, above-mentioned polymer-injecting pump gland for packing box fastener be made further optimization and/or improvements:
as shown in Figure 1, the inner face that is fixed with 3, three afterburning posts 3 of three afterburning posts at the clear width of clip 1 is all positioned on same periphery.Like this, be convenient to the opening position on polymer-injecting pump gland for packing box that the is stuck in more fastening afterburning post 3 on clip 1.
as shown in Figure 1, between the outside of clip 1, be separated with the boosting-rod installing hole 4 of three.Like this, be convenient to boosting-rod 2 and can be arranged on any one boosting-rod installing hole 4, not limited by narrow space.
as shown in Figure 1, clip 1 is semicircle clip.
as shown in Figure 1, be installed with antiskid glue sleeve 5 in the outside of boosting-rod 2.Like this, antiskid glue sleeve 5 is convenient to the better application of force, has prevented that hand from skidding on boosting-rod 2.
