Abstract
The utility model relates to an electric wire and cable joint, comprising an outer shell and a joint body, wherein the outer shell and the joint body are in an integrated structure; a retainer ring is sleeved in the outer shell; an inner ring of the retainer ring is provided with a plurality of toothed bulges; the back of the retainer ring is fixed with an inclining spring which can maintain the retainer ring in an inclining state; the retainer ring is further connected to an unlocking pin which is a column body; one end of the unlocking pin is connected and fixed on the retaining ring; the other end of the unlocking pin extends out of the outer shell. The weight of the joint is light; the structure and the mounting technology are both simple; the joint can be fixed at an end part of a hard conduit tube firmly only by the retainer ring structure in the joint; different structures and elements are fitted; the joint can be connected to a flexible tube or an electric wire and cable sealing fixing member, so as to reach different arms of sealing the hard conduit tube or fixing the electric wire and cable at the end part of the hard conduit tube.
Description
Technical field
The utility model relates to a kind of pipe joint, particularly a kind of pipe joint that is used to protect the rigid line tube end of electric wire.
Background technology
The rigid line pipe that is used for electric wire protection needs parts such as erection joint to be used for fixing electric wire usually and prevents it in the wearing and tearing of mouth of pipe place in its end, or connects flexible pipe and continue the protection electric wire by this zone.Common way is at hard tube end machining internal thread or external screw thread at present, external screw thread and internal thread that the also corresponding processing of joint cooperates with it, thus joint is fixed on the hard tube end.
The deficiency of above-mentioned this method is that the rigid line external diameter of pipe is thicker usually, needs enough wall thickness ability machining screw, causes rigid line pipe weight to increase.In addition, when this kind joint is installed, need the swivel joint screw thread, and the restriction that makes constructing operation often be subject to small space causes installing difficulty.
Summary of the invention
The utility model main purpose is to address the above problem and is not enough, and a kind of in light weight, simple electric wire pipe joint of mounting process is provided.
For achieving the above object, the technical solution of the utility model is:
A kind of electric wire pipe joint, comprise shell, fittings body, described shell and fittings body are integral structure, be arranged with a collar in the described shell, the inner ring of described collar has some dentations, be provided with an inclined springs that can keep described collar to be in heeling condition between one side of described collar and the housing, described collar opposite side also is provided with a latch.
Described latch is a cylinder, and an end of described latch is connected and fixed on the described collar, and the other end of described latch stretches out described shell.
The back side of described collar is provided with the groove that a circle is used to hold described inclined springs.
Content to sum up, electric wire pipe joint described in the utility model, in light weight, simple in structure, cancelled the screw thread processing of original rigid line tube end, simplify the joint mounting process, only need utilize the Spring Clip of joint inside can securely joint be fixed on the rigid line tube end, cooperate different structure and parts, joint can connect flexible pipe or electric wire sealing fixture, to reach sealing rigid line pipe or in the various objectives of rigid line tube end securing electric lines cable.In addition, the volume of this joint is little, is specially adapted to the installing/dismounting operation of small space.
Description of drawings
Fig. 1 structural representation of the present utility model;
Fig. 2 collar schematic diagram.
As depicted in figs. 1 and 2, shell 1, fittings body 2, collar 3, inclined springs 4, latch 5, rigid line pipe 6, dentation 7.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As depicted in figs. 1 and 2, a kind of electric wire pipe joint comprises shell 1, fittings body 2, and shell 1 is an integral structure with fittings body 2, and fittings body 2 is used for being connected as parts such as flexible pipes with other, is used for protecting the rigid line pipe 6 of electric wire to insert this shell 1.
Be arranged with a collar 3 in the shell 1, the inner ring size of collar 3 is slightly larger than the outside dimension of connected rigid line pipe 6.The inner ring of collar 3 has some dentations 7, and the inner ring diameter at collar 3 each place, dentation 7 summits is slightly less than the external diameter of rigid line pipe 6.The profile of each dentation 7 and himself hardness make collar 3 can be stuck in securely on rigid line pipe 6 outer walls when heeling condition.Along rigid line pipe 6 axial withdrawal joints, this external force can be aggravated the heeling condition of collar 3 if any external force, and dentation 7 may snap in the pipe wall material of rigid line pipe 6 part, thereby it is stuck on the rigid line pipe outer wall more securely.After rigid line pipe 6 inserts in the shell 1, collar 3 is enclosed within the outside of rigid line pipe 6 ends, after collar 3 tilts, its projected area on horizontal plane will reduce relatively, external diameter less than rigid line pipe 6, so the dentation 7 of its inner ring just may be stuck on the outer wall of rigid line pipe 6, thereby joint and rigid line pipe 6 are fixed together.
The fixedly connected inclined springs 4 in the back side of collar 3, the other end of inclined springs 4 is fixed on the inwall of shell 1, and the back side of collar 3 is provided with the groove (not shown) that a circle is used to hold inclined springs 4.Inclined springs 4 is when the state that loosens, and the end face that itself and collar 3 are fixed is the inclined plane, and it can be used for keeping collar 3 to be in heeling condition all the time, thereby more securely this joint is fixed on the rigid line pipe 6 all the time.
The also fixedly connected latch 5 of collar 3, as shown in Figure 1, latch 5 is a cylinder, and an end of latch 5 is connected and fixed on the collar 3, and the other end of latch 5 stretches out shell 1.When needs dismounting rigid line pipe 6, latch 5 to be pressed downwards, the collar 3 that is used for being in heeling condition just pushes away reset (promptly being pushed into horizontal level), just the end of rigid line pipe 6 can be withdrawed from from this joint and be pulled down.When needs are plugged rigid line pipe 6, need press latch 5 equally, make collar 3 be in the position of level, after inserting rigid line pipe 6, loosen latch 5, collar 3 has a down dip in the effect of inclined springs 4, and the dentation 7 of collar 3 inner rings just may be stuck on the outer wall of rigid line pipe 6, thereby joint and rigid line pipe 6 are fixed together.
As mentioned above, given in conjunction with the accompanying drawings and embodiments scheme content can derive the similar techniques scheme.In every case be the content that does not break away from technical solutions of the utility model, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of technical solutions of the utility model according to technical spirit of the present utility model.
