Abstract

The utility model discloses a pressure-bearing connecting sleeve. The pressure-bearing connecting sleeve comprises an outer sleeve, an inner sleeve and a cavity arranged between the outer sleeve and the inner sleeve in a matching mode. A plurality of holes are processed in the outer sleeve, the cavity comprises two tracks of annular grooves and a spiral-shaped groove, the two tracks of annular grooves are arranged at two sides of the spiral-shaped groove, and the spiral-shaped groove is communicated with at least one of the holes. Due to the facts that a certain number of holes are formed in the outer sleeve of the pressure-bearing connecting sleeve, the holes are communicated with outside, and at the same time the holes need to be connected with the cavity and the spiral-shaped groove, a controlling piece can be installed into the holes to control the communicated state or the sealing state of the cavity and outside. The pressure-bearing connecting sleeve achieves transporting contacting pressure to other pieces after elastic deformation of the inner sleeve and the outer sleeve through controlling the size of pressure of liquid or gas injected into the cavity, and special functional requirements are achieved.

Description

A kind of joint sleeve of pressure-bearing

Technical field

The utility model relates to a kind of mechanical part that can carry certain pressure.

Background technique

Pressure-bearing mechanical part (hereinafter to be referred as pressure part) mainly is to use as container in most occasions, as is used for splendid attire or accumulating certain amount of fluid, gas, powder etc.; Also be usually used in the control field, as hydraulic servo etc.But in some occasion, need utilize each physics law that equates to pressure in liquid or the gas, obtain the uniform load (this load is often produced by liquid or the gas of big pressure even ultrahigh pressure) of certain pressure, this load acts on certain part surface and makes this part generation resiliently deformable realize specific functional requirement, can control the contact pressure that produces between junction plane and the protection that realizes transmission system or obtains necessarily to hold power tightly and realize swelling connection etc. by resiliently deformable by the size that changes incoming pressure as other component of suitable cooperation; Meanwhile, for reduce harmful effect and the user cost that high-quality liquid or gas produce under factors such as the temperature that changes, rotating speed, reduce the use amount of these liquid or gas as much as possible.Also there is not a kind of pressure-containing member can realize above-mentioned functions well at present.

Summary of the invention

Problem to be solved in the utility model provides a kind of joint sleeve of pressure-bearing, it has specific cavity structure, this cavity structure belongs to the key component of pressure part structure, in certain environment or other condition, require under, can control the open and close state of cavity or make have in the cavity and keep a certain size, stable, preset pressure uniformly.

The joint sleeve of a kind of pressure-bearing of the utility model, it comprises overcoat, interior cover, is arranged on the cavity that matches between the two, put outward and be processed with several holes, cavity comprises circular groove, spiral slot, circular groove is twice, be arranged on the both sides of spiral slot, spiral slot at least with the hole in one communicate.

Outer the putting of the utility model pressure-bearing joint sleeve designed the hole that some is arranged, and the hole communicates with the external world, needs simultaneously be connected with spiral slot with cavity, but controls cavity and the extraneous state that communicates or seal in the control piece load hole and with this; Pass to the contact pressure of other part in the pressure size that the utility model pressure-bearing joint sleeve injects the liquid of cavity or gas by control realizes after the resiliently deformable of overcoat, realize specific functional requirement.

Embodiment

From Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 as can be known, the joint sleeve of a kind of pressure-bearing of the utility model, it comprises overcoat 1, interior cover 2, is arranged on the cavity 4 that matches between the two, be processed with several holes 3 on the overcoat 1, cavity 4 comprises circular groove 6, spiral slot 5, circular groove 6 is twice, is arranged on the both sides of spiral slot 5, spiral slot 5 at least with hole 3 in one communicate.Wherein, cooperating between overcoat 1 and the interior cover 2 can be Spielpassung, also can be interference fit.

Per pass circular groove 6 is made up of two curve baths processing respectively on the periphery of the inner hole surface of overcoat 1 and interior cover 2.The effect of the circular groove 6 on the periphery of the inner hole surface of overcoat 1 and interior cover 2 is: the stress that the inner hole surface of elimination overcoat 1 and the periphery of interior cover 2 produce when pressure-bearing is concentrated.

This is novel to be with overcoat 1 and 2 assemblings of interior cover and the both sides of welding this builtup member, makes both form a single piece, meanwhile forms the cavity 4 of trough of belt.Several holes 3 are arranged on the overcoat 1, and these holes communicate with extraneous, cavity 4, and one of them hole 3 communicates with spiral chute 5, can be from the hole 3 that communicates with spiral chute 5 inject or discharge liquid or gas to cavity 4, and other hole 3 is also as discharging liquid or gas usefulness.

From Fig. 1, Fig. 2, Fig. 3 as can be known, process on the periphery of interior cover 2 when spiral slot 5, the inner hole surface between the twice curve bath 6 of overcoat 1 is the light face.Like this, when in the endoporus of joint sleeve other component being housed, after from hole 3, injecting liquid or gas, liquid or gas are full of whole cavity 4 and produce uniform load at the periphery of interior cover 2 by groove, fitting surface and makes it that resiliently deformable take place, the endoporus of cover 2 is held other component equably tightly in making, this moment the control piece of in hole 3, packing into, can be with the liquid that charges into or gas seal in cavity 4; If unclamp or destroy control piece, liquid or gas in the cavity 4 overflow, and interior cover 2 returns to original state by elastic principle.

From Fig. 4, Fig. 5, Fig. 6 as can be known, process on the inner hole surface of overcoat 1 when spiral slot 5, the periphery between the twice curve bath 6 of interior cover 2 is the light face.Like this, when the cylindrical of joint sleeve is packed the endoporus of other component into, after from hole 3, injecting liquid or gas, liquid or gas are full of whole cavity 4 and produce uniform load in the inner hole surface of overcoat 1 by groove, fitting surface and makes it that resiliently deformable take place, the cylindrical that makes overcoat 1 is other component of swelling equably, this moment the control piece of in hole 3, packing into, can be with the liquid that charges into or gas seal in cavity 4; If unclamp or destroy control piece, liquid or gas in the cavity 4 overflow, and overcoat 1 returns to original state by elastic principle.

As can be seen from the above, but control cavity and the extraneous state that communicates or seal in the control piece load hole and with this, pass to the contact pressure of other part in the pressure size that the pressure-bearing joint sleeve injects the liquid of cavity or gas by control realizes after the resiliently deformable of overcoat, realize specific functional requirement.Therefore, this joint sleeve can control the open and close state of cavity or make have in the cavity and keep a certain size, stable, preset pressure uniformly.
