Abstract
The utility model discloses an extension pipe connecting device. The extension pipe connecting device is respectively connected with one end of a first hose and one end of a second hose, and comprises a tubular body, a first tightening screw cap and a second tightening screw cap, wherein the tubular body is provided with threads; the first tightening screw cap and the second tightening screw cap are sheathed on the periphery of the body and are used for respectively tightening the first hose and the second hose on the body; two ends of the body adopt frustum structures and are matched with the internal diameters of the hoses. The extension device can connect the two sections of hoses quickly through tightening the first tightening screw cap and the second tightening screw cap and is convenient to use; as the body and the tightening screw caps can be separated, the modeling is facilitated; the extension pipe connecting device is good in tightening effect, and has no leakage phenomenon.
Description
Technical field
This utility model relates to the medical sanitary apparatus field, relates in particular to a kind of extension tube connecting device.
Background technology
The infusion set adopted in hospital and medical institutions at present, and all contain flexible pipe as devices such as filter bag, blood taking bags, more even be used to being assemblied in the flexible pipe for medical purpose on instrument, tend in use face the too short problem of hose length, some type products that some production firm does not just wait by be divided into hose length in a series products, increased production cost, also for user, made troubles.
Although people have started to solve for the problems referred to above, for example by two flexible pipes are connected by a device, fluid seepage in flexible pipe, often can occur in poor effect, especially can not use higher the time when pipe is intrinsic pressure.
The utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, this utility model provide a kind of sealing property high for by two sections hose connection extension tube connecting devices.
Technical scheme: for achieving the above object, a kind of extension tube connecting device of the present utility model, with an end of the first flexible pipe and the second flexible pipe, be connected respectively, it is characterized in that: this device comprises to be established threaded tubular body and is placed in described body periphery for respectively the first flexible pipe and the second flexible pipe being tightened in to the first fastening blind nut and the second fastening blind nut on body; The two ends of described body be respectively the frustum structure and with the inner diameter adaptation.
Extension tube connecting device of the present utility model is for connecting two sections flexible pipes by this device, device of the present utility model is not limit size, can use in flexible pipe model coupling.Body interior of the present utility model is tube chamber, and the two ends of outer surface are the halfpace structure, and front end is narrow, and rear end is thick, convenient insertion flexible pipe, and entangle firm according to the characteristic of hose material.
Further, described body is provided with basic ring, described basic ring is provided with respectively the first swivel nut and the second swivel nut to the body two ends, the described first fastening blind nut and the second fastening blind nut comprise outer cylinder body and inner barrel, between described outer cylinder body and inner barrel, are provided with the space that holds the first swivel nut and the second swivel nut; The screw thread of described outer cylinder body and the first swivel nut and the second swivel nut coincide; Described inner barrel is provided with binding thread towards flexible pipe, and along with outer cylinder body is inwardly tightened, described binding thread embeds flexible pipe gradually.
Must illustrate, flexible pipe described here refers to the general designation of the first flexible pipe and the second flexible pipe.
For the ease of tightening, anti-skidding, the described first fastening blind nut and the second fastening screw cap surface are provided with anti-slip veins.
Beneficial effect: a kind of extension tube connecting device of the present utility model is by tightening the first fastening blind nut and the second fastening blind nut can fast be realized two sections hose connection, easy to use, and body and fastening blind nut can separate, be beneficial to modeling, and this this device fastening effective, seepage can not occur.
The accompanying drawing explanation
Fig. 1 is that this utility model is by two sections hose connection schematic cross-sections that are;
Fig. 2 is the schematic appearance of this utility model connecting device.
The specific embodiment
Below in conjunction with accompanying drawing, this utility model is further described.
As shown in Figure 1 and Figure 2, a kind of extension tube connecting device of the present utility model, with the first flexible pipe 1, be connected with an end of the second flexible pipe 2 respectively, it is characterized in that: this device comprises to be established threaded tubular body 3 and is placed in body 3 peripheries for respectively the first flexible pipe 1 and the second flexible pipe 2 being tightened in to the first fastening blind nut 4 and the second fastening blind nut 5 on body 3; The two ends of body 3 be respectively the frustum structure and with the inner diameter adaptation, the first fastening blind nut 4 and the second fastening blind nut 5 surfaces are provided with anti-slip veins 12.
Extension tube connecting device of the present utility model is for connecting two sections flexible pipes by this device, body 3 inside are tube chamber, and the two ends of outer surface are the halfpace structure, and front end is narrow, and rear end is thick, conveniently inserts flexible pipe, and entangles firm according to the characteristic of hose material.By tightening the first fastening blind nut 4 and the second fastening blind nut 5 can fast be realized two sections hose connection, easy to use.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from this utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
