Abstract
The utility model discloses a screw hole sealing element positioning structure, and belongs to the seal positioning technical field. The screw hole sealing element positioning structure comprises an upper cover, a round nut, a sealing element and a lower cover, wherein the round nut is embedded in the upper cover, the sealing element is installed on an installation blocking mouth between the upper cover and the lower cover, a sealing element positioning step is machined at the upper end of a screw mounting hole of the lower cover, and an inner hole of a sealing ring of the sealing element is in interference fit with the outer wall of the sealing element positioning step. The screw hole sealing element positioning structure achieves one-step installation and accurate positioning on the sealing ring portion of the sealing element, guarantees that a screw can not be contacted with the sealing ring of the sealing element and thereby can not damage the sealing ring of the sealing element when the screw is installed, achieves the effect of reliably sealing a screw hole, and simultaneously improves installation efficiency.
Description
Technical field
The utility model belongs to sealing field of locating technology, relates to a kind of screw hole Sealing position structure.
Background technique
Along with the fast development of industrialized level, more and more higher to the requirement of shelter of various instruments and equipment.Be positioned at the product structure of upper and lower covers assembly wall for screw hole, often need to take necessary seal approach at screw hole place, to reach required protection effect.Present stage, the higher product of some requirement of shelter is as the product such as engineering mechanical instruments, controller, and in order not destroy its surface structure, upper and lower covers attachment screw hole multidigit, in assembly wall, seals with the Sealing that rubber material is made between upper and lower covers.As shown in Figure 1, the sealing configuration of its screw installation place is to stretch out an internal diameter at Sealing 3 inner edges to equate with screw 5 external diameters, and external diameter seals erection column seam with the seal ring that upper and lower covers installation joint external diameter equates.When installation, first upper cover 1 is oppositely kept flat, install inner body, then Sealing 3 is placed in to upper cover and installs on seam, finally tighten mounting screw 5 and complete installation.In this sealing configuration, it is only with visual determination, to be alignd with the upper cover mounting column center of circle in the seal ring center of circle that the Sealing seal ring at screw hole place is installed, then lower cover 4 is placed on to press seal part on Sealing 3 carefully, and last mounting screw 5 is fixing.
There is certain defect in this sealing configuration: general Sealing is selected softer rubber material manufacture, and Sealing seal ring part does not have structure to fix its position upper covering after placing, easily displacement; When upper cover end face and Sealing attachment face angle are when larger, the Sealing seal ring part that is placed in upper cover end face is more easily partially slided compared with low direction to inclined-plane and makes the hole heart be difficult to align with screw mounting hole, or when lower cover mounting hole site is not alignd with upper cover mounting hole and slightly when mobile lower cover, Sealing seal ring will be moved and the hole heart is offset, affecting screw installs, in this case, mounting screw easily damages Sealing, so that does not reach required sealing effect in screw installation place.
Model utility content
In order to address the above problem, the utility model provides a kind of screw hole Sealing position structure, thereby has reached preferably by the effect of Sealing location.
The utility model is achieved by following technical solution.
A kind of screw hole Sealing position structure, comprise upper cover, round nut, Sealing and lower cover, described round nut is inlaid in upper cover, and described Sealing is contained on the installation seam between upper cover and lower cover, and described lower cover screw mounting hole upper end is processed with Sealing positioning step.
Between the outer wall of described Sealing seal ring endoporus and Sealing positioning step, it is interference fit.
The thickness of described Sealing seal ring is greater than the height 0.2mm～0.5mm of Sealing positioning step.
The beneficial effects of the utility model are:
A kind of screw hole Sealing position structure described in the utility model, by at lower cover screw mounting hole upper end seal element machining positioning step, and make interference fit between Sealing seal ring and Sealing positioning step, Sealing seal ring part once mounting is put in place and accurately locate, guarantee when screw is installed not contact with Sealing seal ring, it is not caused to damage, reached the sealing effect more reliably that makes screw hole place, improved efficiency of assembling simultaneously.
Brief description of the drawings
Fig. 1 is Sealing position structure schematic diagram of the prior art;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is B-B cross section structure schematic diagram in the utility model.
In figure: 1-upper cover, 2-round nut, 3-Sealing, 4-lower cover, 5-mounting screw, 6-Sealing, 601-Sealing seal ring, 7-lower cover, 701-Sealing positioning step.
Embodiment
Further describe the technical solution of the utility model below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in Figure 2 and Figure 3, a kind of screw hole Sealing position structure described in the utility model, comprise upper cover 1, round nut 2, Sealing 6 and lower cover 7, described round nut 2 is inlaid in upper cover 1, described Sealing 6 is contained on the installation seam between upper cover 1 and lower cover 7, and described lower cover 7 screw mounting hole upper ends are processed with Sealing positioning step 701.
Between the outer wall of described Sealing seal ring 601 endoporus and Sealing positioning step 701, it is interference fit.
The thickness of described Sealing seal ring 601 is greater than the height 0.2mm～0.5mm of Sealing positioning step 701.
When installation, first Sealing 6 is arranged on the rabbet groove of lower cover 4, Sealing seal ring 601 is set on Sealing positioning step 701, again the whole lower cover structure assembling is installed on upper cover 1, pass lower cover screw hole with mounting screw 5 and coordinate with the round nut 2 being inlaid in upper cover 1, tighten mounting screw 5, Sealing 6 is compressed, until 2 times end in contact of Sealing positioning step 701 upper ends and round nut complete installation.
