Abstract
The utility model discloses a kind of straight coupling, it includes a body and a cutting ferrule, there is the fluid passage and a jointing for axially penetrating through body two ends on body, cutting ferrule is removably nested with jointing, an annular groove is provided with the outer wall of described body, described cutting ferrule includes a taper choke, and taper choke is connected in annular groove.The utility model need not set plastic washer, so as to reduce amount of parts.
Description
Technical field
The utility model is related to a kind of straight coupling.
Background technology
Current straight coupling, which is generally comprised on the body of a tubular, a cutting ferrule and a plastic washer, body, to be had axially
There is jointing, jointing connects with one end of body, plastic washer on fluid passage through body two ends, body
It is nested with and is fixed on body, cutting ferrule is nested with the jointing of body, and in order to avoid cutting ferrule is from the jointing of body
Come off, it is necessary to which cutting ferrule is fixed on plastic washer while being nested with.So, due to needing to set plastic washer so that this leads directly to
Joint parts are more, and manufacturing cost is higher.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of straight coupling, and it need not set plastic washer,
So as to reduce amount of parts.
In order to solve the above technical problems, the straight coupling that the utility model is provided, it includes a body and a cutting ferrule, body
The upper fluid passage and a jointing that body two ends are axially penetrated through with one, cutting ferrule is removably nested with jointing,
An annular groove is provided with the outer wall of described body, described cutting ferrule includes a taper choke, taper choke clamping
In annular groove.
Preferably, several annular double wedges are provided with the outer wall of described jointing, several annular double wedge edges
The axis direction of jointing is spaced apart.
Preferably, described straight coupling also includes a protective case, the closing of protective case one end and another end opening, protection
Set is removably nested with jointing.
After above structure, the utility model compared with prior art, has the following advantages that：
Annular groove, the taper choke clamping of cutting ferrule are provided with straight coupling of the present utility model, the outer wall of body
In the annular groove, so allow for cutting ferrule and fix, cutting ferrule can be avoided to be come off from body, the utility model eliminates modeling
Backing strap circle, so as to reduce product component quantity, reduces manufacturing cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, the utility model straight coupling, it includes a body 1, a cutting ferrule 2, a sealing ring 8, an air ring
4, one vinyl cover 5, a jump ring 6 and a sleeve 7 are enclosed, body 1, which has on first end and the second end, body 1, has one to axially penetrate through
The jointing 102 of fluid passage 101 and one at the two ends of body 1, jointing 102 is engaged with the first end of body 1, and cutting ferrule 2 can
Being nested with jointing 102 for dismounting, an annular groove 103, described cutting ferrule 2 are provided with the outer wall of described body 1
The taper choke 202 of the one end of cylindrical portion 201 is connected to including a cylindrical portion 201 and one, taper choke 202 is connected to annular
In groove 103, so so that cutting ferrule 2 is fixed on body 1 and will not fall off, when needing to remove cutting ferrule 2 from body 1, only
Need to apply cutting ferrule 2 axial force to remove the taper choke 202 of cutting ferrule 2 out of annular groove 103, you can take
The first end of body 1, is then connected by lower cutting ferrule 2 by cutting ferrule 2 with pipeline to be connected.
Vinyl cover 5 is arranged on the second end of body 1, and sealing ring 8 is arranged on the inwall of body 1, ring washer 4, card
Spring 6 and sleeve 7 are arranged on the inwall of vinyl cover 5, and sleeve 7 is used to be connected with pipeline to be connected.
Several annular double wedges 1021 are provided with the outer wall of described jointing 102, several annular double wedges 1021
Be spaced apart along the axis direction of jointing 102, so, by cutting ferrule 2 by the first end of body 1 and pipeline to be connected
When being connected, cutting ferrule 2 can be clamped on jointing 102, now due to being provided with annular double wedge on jointing 102
1021, cutting ferrule 2 and the fixation of jointing 102 can be caused.
Described straight coupling also includes a protective case 3, the closing of the one end of protective case 3 and another end opening, and protective case 3 is removable
That unloads is nested with jointing 102, so, and during straight coupling is transported and is deposited, protective case 3 can be to body 1
Jointing 102 is protected, and prevents the first end end of jointing 102 and body 1 to be deformed due to collision, and
Install before straight coupling, protective case 3 is removed.
Explanation only is made that using preferably example with regard to the utility model above, but is not to be construed as to claim
Limitation, structure of the present utility model can have other changes, be not limited to said structure.In a word, it is all of the present utility model only
The various change made in vertical scope of the claims is in protection domain of the present utility model.
