a pipe with a drop-proof connector comprises more than one section of pipe body, wherein the head end and the tail end of each section of pipe body are respectively provided with a socket section and a socket section, the socket section of each section of pipe body can be inserted into the socket section of the adjacent pipe body,
the inner wall of the bellmouth section is also provided with an annular limiting groove which is positioned between the outer port of the bellmouth section and the sealing ring installation cavity and is arranged around the inner wall of the bellmouth section;
the outer peripheral wall of the socket section is provided with more than one group of unhooking-proof components which are arranged around the outer peripheral wall of the socket section at intervals, each group of unhooking-proof components comprises a hook seat fixedly connected with the outer peripheral wall of the socket section and an elastic hook piece connected with the outer wall of the hook seat, one end of the elastic hook piece is fixedly connected with the outer wall of the hook seat, and the other end of the elastic hook piece extends outwards in an inclined manner from a connecting part to the direction back to the outer port of the socket section;
when the socket section inserts in the socket section that corresponds, the elasticity hook piece receives can get into annular spacing inslot through the outer port of socket section after the extrusion deformation, later can reset the joint in annular spacing inslot under self elastic action.
In this scheme inserted the socket section, the butt of socket section was held the position and is located the linkage segment of socket section, then annular spacing groove card is located the anticreep barb subassembly outside, make two sections tubular product connect and be difficult to drop.
Further, insertion is facilitated, and falling off is further prevented: the socket section periphery wall be by socket section outer port to deviating from the truncated cone face that the external diameter of socket section outer port direction increases gradually, socket section inner wall be with socket section outer wall's truncated cone face of truncated cone face matched with.
Further, the hook seat is fixedly connected with the peripheral wall of the socket section through a locking device. The locking device can be a screw, a screw or a bolt and other components.
Furthermore, in order to facilitate the clamping of the elastic hook piece, the annular limiting groove is formed by an annular groove surface perpendicular to the axis of the pipe body and a truncated cone surface which is connected with the outer periphery of the annular groove surface and extends inwards in an inclined mode, and the annular groove surface is close to the outer port of the socket section.
Furthermore, the pipe body is a double-wall corrugated pipe formed by sleeving and connecting a cylindrical pipe wall arranged on an inner layer and a corrugated pipe wall which is arranged on an outer layer and provided with a plurality of wave crests and wave troughs.
Compared with the prior art, the utility model discloses following beneficial effect has:
(1) the utility model discloses a tubular product is pegged graft conveniently, is difficult to drop, and it is very convenient to use moreover.
(2) The utility model discloses a tubular product sealing performance is good, is difficult to reveal.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description.
Example 1
A pipe with a drop-proof connector comprises more than one section of pipe body 1, the head and tail ends of each section of pipe body 1 are respectively provided with a socket section 1-1 and a socket section 1-2, the socket section 1-1 of each section of pipe body 1 can be inserted into the socket section 1-2 of the adjacent pipe body 1,
the pipe fitting comprises a pipe fitting body 1 and a socket section 1-2, wherein the socket section 1-2 is provided with at least one annular wave crest 1-3 protruding outwards, the inner cavity of the annular wave crest 1-3 is communicated with the inner cavity of the pipe fitting body 1 to form an annular sealing ring installation cavity 3-1 for installing a sealing ring 3, and the inner wall of the socket section 1-2 is also provided with an annular limiting groove 3-2 which is positioned between the outer port of the socket section 1-2 and the sealing ring installation cavity 3-1 and is arranged around the inner wall of the socket section 1-2;
the peripheral wall of the socket section 1-1 is provided with more than one group of unhooking prevention assemblies 2 arranged around the peripheral wall of the socket section 1-1 at intervals, each group of unhooking prevention assemblies 2 comprises a hook seat 2-1 fixedly connected to the peripheral wall of the socket section 1-1 and an elastic hook piece 2-2 connected to the outer wall of the hook seat 2-1, one end of the elastic hook piece 2-2 is fixedly connected with the outer wall of the hook seat 2-1, and the other end of the elastic hook piece extends outwards in an inclined manner from a connecting part to a direction away from the outer port of the socket section 1-1;
when the socket section 1-1 is inserted into the corresponding socket section 1-2, the elastic hook piece 2-2 can enter the annular limiting groove 3-2 through the outer port of the socket section 1-2 after being extruded and deformed, and then can be reset and clamped in the annular limiting groove 3-2 under the elastic action of the elastic hook piece.
In this scheme inserted the socket section, the butt of socket section was held the position and is located the linkage segment of socket section, then annular spacing groove card is located anticreep barb subassembly 2 outside, make two sections tubular product connect and be difficult to drop.
This embodiment facilitates insertion and further prevents falling off: the outer peripheral wall of the socket section 1-1 is a truncated cone surface with the outer diameter gradually increasing from the outer port of the socket section 1-1 to the direction departing from the outer port of the socket section 1-1, and the inner wall of the socket section 1-2 is a truncated cone surface matched with the truncated cone surface of the outer wall of the socket section 1-1.
In the embodiment, the hook seat 2-1 is fixedly connected with the peripheral wall of the socket section 1-1 through a locking device 4. The locking device can be a screw, a screw or a bolt and other components.
In order to facilitate the elastic hook plate to be clamped into the annular limiting groove 3-2, the annular limiting groove 3-2 is composed of an annular groove surface perpendicular to the axis of the pipe body 1 and a truncated cone surface connected with the outer periphery of the annular groove surface and extending obliquely inwards, wherein the annular groove surface is close to the outer port of the socket section 1-2.
The pipe body 1 of the present embodiment is a double-wall corrugated pipe formed by sleeving and connecting a cylindrical pipe wall arranged on an inner layer and a corrugated pipe wall arranged on an outer layer and having a plurality of wave crests and wave troughs. May be provided as a single wall bellows as desired.
While the present invention has been shown and described with reference to particular embodiments and alternatives thereof, it will be understood that various changes and modifications can be made without departing from the spirit and scope of the invention. It is understood, therefore, that the invention is not to be limited, except as by the appended claims and their equivalents.
