Abstract

The utility model discloses a pipe fitting connection device which comprises a strip member for connecting pipe fittings and a clamping member for compacting the strip member, wherein the strip member is provided with a buckling part; the clamping member is provided with a buckling matching part matched with the buckling part; and the buckling part is matched with the buckling matching part. According to the utility model, a strip member with multiple through holes or grooves is buckled with a hard clamping member to fasten a hose sleeved on a hard pipe; the pipe fitting connection device is suitable for connecting and fastening the pipe fittings of all diameter dimensions; and moreover, when the pipe fitting is aged and deforms to get loose, the buckling tightness between the clamping member and the strip member can be adjusted to enhance the sealing effect. The whole structure is easy to use and quick and convenient to mount.

Description

A kind of pipe connecting device
Technical field
The utility model relates to a kind of pipe connecting device, and particularly a kind of being applicable to is connected to the pipe connecting device on the hard tube with flexible pipe.
Background technique
In general, for such as the agricultural water delivery hose of processing with soft materials such as plastics, natural gas transport flexible pipe, need be firmly and do not have leak connected to as on the water source or the hard tube of gas supply source with it.
For example, notice of authorization number is CN201428882Y, and invention and created name discloses a kind of pipe fitting connecting head for the Chinese utility model patent of " hard tube and flexible pipe jointing "; This jointing is made up of joint, locking nut, rubber seal; Screw thread and hard tube interface end that joint is provided with the hose connection end, is complementary with locking nut, the hose connection end is provided with anti-skidding double wedge, is provided with screw thread in the hard tube interface end; Appearance is provided with fastening six sides; Tightening nut one end internal surface is provided with screw thread, and outer surface is provided with fastening six sides, the other end internal surface be provided with joint hose connection section on the conical surface that is complementary of anti-skidding double wedge coning angle.The rubber seal lining is inner in joint hard tube hub cavity.When using this connection joint, be connected firmly technical requirementss such as favorable sealing property though can reach; But structure is too complicated; Trouble is installed, and after in a single day tightening nut reinforced moulding, flexible pipe and hard tube were all collected together the deformation in certain limit; But the deformation of tightening nut can only be in certain scope, and lasting sealing has to be strengthened.Simultaneously, the adaptable pipe fitting diameter of tightening nut is limited, wants to satisfy with this linkage structure the connection of the pipe fitting of various different-diameter sizes, almost is impossible.
The model utility content
To above existing technology, the utility model provides a kind of firm and leak free pipe connecting device that is connected on the hard tube of the flexible pipe with various diameter dimensions that can be easily and fast, and concrete technological scheme is following:
A kind of pipe connecting device, comprise one be used for connection pipe fitting strap-like member and be used for clamping element that this strap-like member is compressed, described strap-like member is provided with the engagement portion, described clamping element is provided with the snap fit portion that matches with described engagement portion; Described engagement portion and the clamping mutually of described snap fit portion; Described engagement portion is through hole or groove, described clamping element be the circular arc card, be provided with jut in the card both ends of the surface, this jut becomes the snap fit portion that through hole or groove with described engagement portion fasten.The card outward appearance of circular arc is more smooth, combines closelyr with strap-like member, and fastening weak joint when reducing flexible pipe and being connected with hard tube, and process step simplification reduce the cost.
Further, the engagement portion on the described strap-like member distributes along whole length direction.
Further, described strap-like member is a stepped shape cross section, and described engagement portion is arranged on this stepped shape middle part.
Further, described strap-like member has identical thickness except that through hole or groove part.
Further, described strap-like member is that rubber-like plastics or rubber material are processed.
Further, described clamping element is that hard metal material is processed.
The utility model adopts a strap-like member that has some through holes or groove to engage with a hard clamping element; The flexible pipe of adapter sleeve on hard tube; The connection of tubing that is applicable to all diameter dimensions is fastening; And occur loosening the time when the aging distortion of tubing, can adjust elasticity that clamping element engages with strap-like member with the enhanced leaktightness effect.Total is used simple, convenience quick for installation.
Description of drawings
Accompanying drawing 1 connects the sectional view of the assembling condition of two pipe fittings for the utility model specific embodiment.
Accompanying drawing 2 is the perspective view of the utility model specific embodiment strap-like member.
Accompanying drawing 3 is the utility model specific embodiment strap-like member and clamping element fit system schematic representation.
Embodiment
Further specify below in conjunction with the structure and the Placement of accompanying drawing the utility model.
Like Fig. 1-shown in Figure 3; A kind of pipe connecting device; Comprise one be used to connect flexible pipe 1 and hard tube 2 strap-like member 3 and be used for clamping element 4 that this strap-like member 3 is compressed, strap-like member 3 is provided with engagement portion 5, clamping element 4 is provided with the snap fit portion 6 that matches with engagement portion 5; Engagement portion 5 and snap fit portion 6 clamping mutually.
Engagement portion 5 on the strap-like member 3 distributes along whole length direction.Engagement portion 5 is a through hole shown in Figure 2, or groove shown in Figure 3.Strap-like member 3 is a stepped shape cross section, and engagement portion 5 is arranged on this stepped shape middle part.Strap-like member 3 has identical thickness except that throughhole portions.Clamping element 4 be the circular arc card, be provided with jut in the card both ends of the surface, this jut become and through hole or the snap fit portion 6 that groove fastens of engagement portion 5.Strap-like member 3 is processed for rubber-like plastics or rubber material.Clamping element 4 is processed for hard metal material.Hard metal material has strong clamping power makes strap-like member 3 fastening being distributed in around the flexible pipe 1.
The utility model is not limited to the structure of engagement portion on shape and the strap-like member of clamping element, and all fall within the scope that the utility model is asked for protection through the connection set that the fastening flexible pipe of engaging strap-like member is connected with hard tube.
