Utility model content

The purpose of this utility model is defect for prior art and deficiency, provides a kind of structure simple, the hermetically-sealed construction of intercom housing reasonable in design, easy to use.

For achieving the above object, the technical solution adopted in the utility model is:

The hermetically-sealed construction of a kind of intercom housing described in the utility model, comprises back casing and sealing strip, and described sealing strip is made up of sealing ring and several tie rods, and tie rod one end is fixedly installed on sealing ring lower surface, and sealing ring and tie rod are through being made of one piece; The upper madial wall of described back casing arranges the ring side groove matched mutually with sealing ring, and the second stage face of described back casing is provided with several fixing holes matched mutually with tie rod, and one end of sealing ring is embedded in the groove of ring side, and tie rod is embedded in fixing hole.

Further, described tie rod is made up of lower cone and column body, and column body one and lower cone are fixedly connected, and the column body other end and sealing ring lower surface are fixedly connected, and sealing ring, lower cone and column body are through being made of one piece; Described fixing hole is by the lower cone hole matched mutually with lower cone and form with the upper circular hole that column body matches mutually, and lower cone is embedded in lower cone hole, and column body is embedded in upper circular hole.

Further, the rectangular shape of the cross section of described sealing ring.

After adopting said structure, the utility model beneficial effect is: the hermetically-sealed construction of a kind of intercom housing described in the utility model, comprise back casing and sealing strip, described sealing strip is made up of sealing ring and several tie rods, tie rod one end is fixedly installed on sealing ring lower surface, and sealing ring and tie rod are through being made of one piece; The upper madial wall of described back casing arranges the ring side groove matched mutually with sealing ring, and the second stage face of described back casing is provided with several fixing holes matched mutually with tie rod, and one end of sealing ring is embedded in the groove of ring side, and tie rod is embedded in fixing hole.When using the utility model, by tie rod is nested in fixing hole, be nested in the groove of ring side by sealing ring medial extremity, thus avoid occurring when assembling or dismantle intercom the phenomenon that sealing strip comes off from back casing, both ensured the dustproof and waterproof function of back casing sidewall being placed sealing strip, be user-friendly to again.It is simple that the utility model has structure, arranges rationally, the advantages such as cost of manufacture is low.

Embodiment

Below in conjunction with accompanying drawing, the utility model is further described.

As Figure 1-4, the hermetically-sealed construction of a kind of intercom housing described in the utility model, comprise back casing 1 and sealing strip 2, described sealing strip 2 is made up of sealing ring 2-1 and several tie rods 2-2, tie rod 2-2 one end is fixedly installed on sealing ring 2-1 lower surface, and sealing ring 2-1 and tie rod 2-2 is through being made of one piece.

The upper madial wall of described back casing 1 arranges the ring side groove 1-1 matched with sealing ring 2-1 phase, the second stage face of described back casing 1 is provided with several fixing hole 1-2 matched with tie rod 2-2 phase, one end of sealing ring 2-1 is embedded in the groove 1-1 of ring side, and tie rod 2-2 is embedded in fixing hole 1-2; Thus avoid occurring when assembling or dismantle intercom the phenomenon that sealing strip comes off from back casing.

Further, described tie rod 2-2 is made up of lower cone 2-2a and column body 2-2b, column body 2-2b mono-and lower cone 2-2a are fixedly connected, and the column body 2-2b other end and sealing ring 2-1 lower surface are fixedly connected, and sealing ring 2-1, lower cone 2-2a and column body 2-2b are through being made of one piece.

Described fixing hole 1-2 is by the lower cone hole 1-2a matched with lower cone 2-2a phase and form with the upper circular hole 1-2b that column body 2-2b phase matches; Lower cone 2-2a is embedded in lower cone hole 1-2a, and column body 2-2b is embedded in upper circular hole 1-2b, ensures sealing strip difficult drop-off further.

Further, the rectangular shape of cross section of described sealing ring 2-1, the rectangular shape of cross section of ring side groove 1-1, increases ring side groove 1-1 to the fastening ability of sealing ring 2-1.

When using the utility model, by tie rod is nested in fixing hole, be nested in the groove of ring side by sealing ring medial extremity, thus avoid occurring when assembling or dismantle intercom the phenomenon that sealing strip comes off from back casing, both ensured the dustproof and waterproof function of back casing sidewall being placed sealing strip, be user-friendly to again.In addition, this structure is simple, reasonable in design, low cost of manufacture.

The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
