Abstract

The utility model discloses a sealing joint, which comprises a joint body with the inner diameter adapting to the outer diameter of shaft type parts, wherein the joint body comprises a section of position limiting step and a section of threaded section, the position limiting step can be leaned and pressed on the inner side of a wall plate, the threaded section can extend out of an installing hole formed in the wall plate, and the threaded section of the joint body extends out of the installing hole formed in the wall plate and is then tightly screwed by a screw nut. After the adoption of the structure, holes can be directly formed in the wall plate, the position of one end of the joint body is limited by the position limiting step, and the other end of the joint body extends out of the installing hole and is then tightly screwed and pressed on the wall plate by one screw nut, so any auxiliary part welding is not needed on the wall plate, the structure is simple, the perforation tapping step is not needed, the welding is also not needed, the processing, the mounting and the dismounting are very simple and convenient, the manufacturing cost is low, meanwhile, the adopted sealing structure is in static sealing, the sealing reliability is high, in addition, the shaft type parts and the wall plate do not adopt fixed connection, certain axial jumping can be realized, and axial displacement generated through vibration and impact can be born.

Description

SEALING FITTING

Technical field

The utility model relates to a kind of for being tightly connected of wallboard and axial workpiece, specifically a kind of SEALING FITTING.

Background technique

Will be through the panel joining structure of casing for some axial workpieces in machine-building process, generally adopt traditionally welded flange on wallboard, the tapping of punching on flange again, and then axial workpiece is passed from wallboard, the last Placement sealing by seal ring again, traditional this Hermetical connecting structure, on the one hand, in manufacturing process, because the parts of needs processing are more, make its processing difficulties complicated, also very high to the required precision in hole in course of working, be difficult for processing; On the one hand, what in connection procedure, form is rigidly connected, and makes to install rear axial workpiece relative with joint part fixing in addition, can not bear vibration and impact.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of simple in structure, and SEALING FITTING simple and convenient and that can bear vibration and impact is installed in processing.

In order to solve the problems of the technologies described above, SEALING FITTING of the present utility model, comprise the joint body that an internal diameter and axial workpiece external diameter adapt, described joint body comprises one section of limited step and one section of thread section that can stretch out the mounting hole on wallboard that can be pressed over wallboard inner side, and the thread section of joint body is screwed by a nut after stretching out the mounting hole on wallboard.

Between described limited step and wallboard inner surface, the first O-ring seals is installed.

On the internal diameter at described joint body upper limit step place, have circular groove, circular groove is interior by the second O-ring seals is installed.

Adopt after above-mentioned structure, due to the joint body with limited step and thread section arranging, thus can be on wallboard directly perforate, joint body one end is spacing by limited step, the other end is screwed and is pressed on wallboard by a nut after stretching out mounting hole, making no longer to need to do any auxiliary component on wallboard welds, it is simple in structure, the tapping step of not punching, also without welding, processing is installed and is dismantled all very simple and convenient, low cost of manufacture, the sealing configuration simultaneously adopting is static seal, sealing reliability is high, make in addition not to be fixedly connected with between axial workpiece and wallboard, can there is certain axial float, bear some vibrations and impact the axial displacement producing.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model SEALING FITTING;

Fig. 2 is the A place structure for amplifying schematic diagram of Fig. 1.

Embodiment

Below in conjunction with the drawings and specific embodiments, SEALING FITTING of the present utility model is described in further detail.

As shown in the figure, SEALING FITTING of the present utility model, comprise the hollow joint body 1 that an internal diameter and axial workpiece adapt, during installation, can make joint body 1 be enclosed within on axial workpiece, the axial workpiece external diameter of the internal diameter of joint body 1 and demand coordinates, joint body 1 is divided into two sections, wherein one section is spacing section of can be pressed over limited step 2 inside wallboard and form, other one section is the thread section 3 that can stretch out the mounting hole on wallboard, during installation, spacing section is carried out spacing with the inner side of wallboard, thread section is reached outside the mounting hole on wallboard, the thread section of joint body 1 is screwed by a nut 4 after stretching out the mounting hole on wallboard, make thus it from the other side of wallboard, clamp wallboard, the first O-ring seals 5 is installed between limited step 2 and wallboard inner surface, on the internal diameter at joint body 1 upper limit step place, have circular groove, in circular groove, by the second O-ring seals 6 is installed, as can be seen here, the two circle seal rings that the first O-ring seals 5 and the second O-ring seals 6 form can play good sealing effect.
