Abstract
The utility model aims to provide a liquid circulation sealing device, so as to solve the problems of complicated design and large occupied space of the traditional sealing method for liquid transmission in electronic equipment. The device adopts a bolt-shaped structure and is provided with external threads; one end of a screw cap of the device is sealed; one end of a stud is opened; the stub is hollow; a plurality of holes are uniformly distributed on the side wall of the stub along the radial circumference of the stub in the positions corresponding to a horizontal pipeline inside a first part; and the sum of the widths of the holes on the radial circumference of the stub is larger than 1/4 of the radial circumference of the stub. The device has a brief structure and can be completely embedded into the electronic equipment, so as to avoid occupying additional space; and the sealing effect is good and the installation is convenient.
Description
Technical field
The utility model relates to a kind of liquid sealing device, is specifically related in the electronic equipment of liquid transfer is arranged to preventing the Seal Design that its leakage is carried out.
Background technique
In the electronic equipment of liquid transfer is arranged, should consider fixedly connected reliably two parts, also must make liquid from from a part flow to another part, and need prevent that liquid from revealing.
Traditional encapsulating method mainly is to adorn O-ring seals between part, and is fastening with screw around seal ring again, prevents leak of liquid.This realization not only designs complexity, and it is very big to take up room, and is difficult to realize in the harsh place of some spatial requirement.The fluid pipe of especially working as the first part inside is that the fluid pipe of substantially horizontal, the second part inside is a vertical direction, more is difficult to handle.
Therefore, press for a kind of new structure of development, address the above problem.
The model utility content
The utility model aims to provide a kind of liquid communication seal arrangement, and traditional approach carries out the design of the encapsulation process in liquid transfer process complexity in the electronic equipment, big problem takes up room to solve.
The technical solution of the utility model is as follows:
A kind of liquid communication seal arrangement, be stud mounted construction, has outside thread, its nut one end sealing, double-screw bolt one end opening and double-screw bolt hollow, position along double-screw bolt radial circumference corresponding first part inner horizontal pipeline on the sidewall of double-screw bolt is evenly distributed with a plurality of holes, and the width sum of described a plurality of holes on the double-screw bolt radial circumference is greater than 1/4th double-screw bolt circular radial girths.
Above-mentioned hole is waist shaped hole, and promptly the hole that directly makes progress of bolt is wide long less than the hole on axially, has guaranteed the rigidity of this hollow side opening type structure like this.
Above-mentioned waist shaped hole reasonably number is 4-8.
Above-mentioned nut bottom is provided with first seal ring, and the surface of contact position that is positioned at two parts that are mounted on the screw rod is socketed with second seal ring; Like this, guaranteed seal at two ends up and down.
All the diameter with described horizontal pipeline is suitable for the length that above-mentioned waist shaped hole makes progress at stud shaft; Promptly equal or waist shaped hole is a little slightly long, makes not retardance of liquid communication.
Above-mentioned nut top is provided with yi word pattern or cross cutting; So conveniently tight a bolt.
The optimum number of above-mentioned waist shaped hole is 6.
Above-mentioned nut bottom also is provided with in order to embed the seal groove of first seal ring, makes at the sealing effect of this device upper end better.
The utlity model has following advantage:
1, good sealing effect, easy for installation.
2, structure embeds in the electronic equipment concisely, fully, not the occupying volume external space.
3, product can be mass-produced, and applied range.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model use principle figure.
The drawing reference numeral explanation:
1-first part, 2-second part, 3-waist shaped hole, 4-screw thread, 5-seal groove, 6-first seal ring, 7-second seal ring.
Embodiment
The utility model adopts special T type structural member to realize the sealing problem in the liquid transfer process in the electronic equipment, solves other conventional methods big problem that takes up room.
This liquid communication seal arrangement is a stud mounted construction, has outside thread, its nut one end sealing, double-screw bolt one end opening and double-screw bolt hollow, position along double-screw bolt radial circumference corresponding first part inner horizontal pipeline on the sidewall of double-screw bolt is evenly distributed with a plurality of waist shaped holes, and waist shaped hole is generally 4-8.The width sum of this 4-8 waist shaped hole on the double-screw bolt radial circumference is greater than 1/4th double-screw bolt circular radial girths.Be provided with first seal ring in the nut bottom, the surface of contact position that is positioned at two parts that are mounted on the screw rod is socketed with second seal ring; Like this, guaranteed seal at two ends up and down.All the diameter with described horizontal pipeline is suitable for the length that waist shaped hole makes progress at stud shaft, and promptly equal or waist shaped hole is a little slightly long, makes not retardance of liquid communication.The nut top is provided with yi word pattern or cross cutting; So conveniently tight a bolt.The nut bottom also is provided with in order to embed the seal groove of first seal ring, makes at the sealing effect of this device upper end better.
As shown in Figure 1, this model utility is a T font structure, and lower middle portion is hollow, has 6 waist shaped holes around the centre.Outside thread is arranged at the bottom, and seal groove is arranged at top, and a word opening is arranged at the top.
As shown in Figure 2, this liquid communication seal arrangement is assemblied on first part 1 and second part 2, and 1 O RunddichtringO is housed in the seal groove on structure top, between first part 1 and second part 2 second seal ring is housed.During installation, this device is inserted in first part 1, screw then and make the double-screw bolt front end stretch in second part 2, and form screw threads for fastening.Liquid flows to waist shaped hole from first part 1, by flowing to second part 2 from the structure bottom behind the waist shaped hole, realizes liquid flowing in two parts.Two O RunddichtringOs are with the upper and lower double-screw bolt of waist shaped hole and the clearance seal between the part.
Self has screw thread the utility model, and pretightening force is arranged after second part 2 is connected, and adds O-ring seals, can prevent that liquid from revealing.In addition, can also adopt modes such as the size of regulating this structural member open interior, quantity to regulate the flow size.
