Example 1:

as shown in figure 1, the hose joint of the 45-degree arc-shaped plastic rib spiral pipe is particularly suitable for the fields of new energy automobiles, rail traffic, railways, machine tools, machinery manufacturing, air-conditioning refrigeration equipment and the like which need to be connected with the plastic rib spiral pipe.

This hose connector includes the body 100 of connecting and is used for lock to connect the body 100 and mould the lock nut 200 of muscle spiral pipe, connects body 100 and lock nut 200 threaded connection, and through using lock nut 200 to be the most main fixed tensile resistance structure of pulling out, the structure is small and exquisite for overall structure height reduces by a wide margin. In addition, the material of the joint body 100 and the lock nut can be the same as that of the conventional hose joint, and nylon is adopted, so that the weight of the hose joint is light, and the cost is low.

The joint body 100 is bent in an arc shape of 45 degrees, that is, the included angle between the axes of the two ends of the joint body 100 is 45 degrees, and the central angle of the cross section arc line at the bending position is 45 degrees. Through setting up the connector body 100 to 45 arc bending to can the bending be qualified for the next round of competitions, be suitable for the transform position of being qualified for the next round of competitions, and non-right angle structure also reduces hose coupling and bears the side direction shearing force, and the arc bending makes through wires hole rounding off simultaneously, thereby makes the threading smooth and easy, prevents that the cable from cutting open, effectively protects the cable.

One end of the connector body 100, which is far away from the lock nut 200, is provided with the metal reinforcing ring 110, so that the bearing capacity of the conventional nylon connector body 100 is enhanced, and because the end is generally provided with a thread connected with equipment, the corresponding position of the metal reinforcing ring 110 also comprises a thread ring part 112, so that the high impact resistance of the thread end of the outgoing line is improved. Meanwhile, the proportion of the metal reinforcing ring 110 is small, so that the overall weight of the product can be effectively reduced and the product cost can be controlled compared with the all-metal joint body 100.

The metal reinforcing ring 110 further includes a hexagonal ring portion 111, and the hexagonal ring portion 111 and the threaded ring portion 112 are sequentially disposed away from the lock nut 200. Can strengthen the back moment of torsion of moulding plastics through hexagonal ring portion 111, prevent that metal reinforcing ring 110 from deviating from, specifically, the ring shape product is than the hexagonal face product, and the contact surface increases, and the ring shape metal reinforcing ring product is than the destructive torque test of metal reinforcing ring needs bigger moment of torsion. Preferably, the material of the metal reinforcing ring 110 is copper, and since the hexagonal copper bar is an existing mold-opening product, the processing cost can be further reduced.

The coupling body 100 is provided with a stopper 120 for wrapping or semi-wrapping the hexagonal ring portion 111, thereby reinforcing the connection of the metal reinforcing ring 110 and the coupling body 100. The hexagonal ring portion 111 may have a protrusion 1111 extending outward along a radial direction of an inscribed circle thereof, and a corresponding position of the limiting portion 120 is provided with a groove, thereby further enhancing a connection stability of the metal reinforcing ring 110 and the coupling body 100.

The connector body 100 and the metal reinforcing ring 110 are integrally formed by injection molding, so that the processing cost can be reduced, the inside threading hole of the connector body 100 is smooth in surface, namely, the inner wall of the connector body 100 is a smooth surface, and the cable can be better protected.

Example 2:

in addition to embodiment 1, in this embodiment, an elastic locking ring 130 is provided at one end of the joint body 100 for connection with the lock nut 200. As shown in fig. 2, the elastic locking ring 130 includes a plurality of locking wings 131, and the plurality of locking wings 131 are spaced apart in a circumferential direction of the elastic locking ring 130, that is, in a circumferential direction of the coupling body 100, so that the elastic locking ring 130 can be offset in a radial direction. It can be understood that one end of the locking wing 131 close to the metal reinforcing ring 110 is connected to the joint body 100, and there is a gap between the locking wing 131 and the joint body 100 for the insertion of the plastic reinforced spiral pipe.

The inside of the lock nut 200 is provided with a guide ring 210, the inner diameter of the guide ring 210 is gradually reduced along the opposite direction of the locking direction, as shown in the installation direction of fig. 1, the lock nut 200 is locked from bottom to top, the guide ring 210 is gradually reduced from top to bottom so as to gradually press the locking wing 131 and tightly clamp the plastic rib spiral tube between the connector body 100 and the elastic locking ring 130, and meanwhile, the guide ring 210 and the elastic locking ring 130 are matched to realize effective contact with the plastic rib spiral tubes with different pitches, so as to achieve the fastening effect and improve the adaptability of the hose connector.

As shown in fig. 2, the outer side surface of the locking wing 131 is preferably an inclined surface 1311 adapted to the guide ring 210, so that the guide ring 210, that is, the lock nut 200 can smoothly move from bottom to top and lock the coupling body 100 and the plastic-reinforced spiral pipe. The locking wing 131 is provided with an outer convex rib 1312 on the outer side and an inner convex rib 1313 on the inner side. The outer protrusion 1312 increases friction with the guide ring 210, is not easily slid, and increases a fixing pull-out resistance of the lock nut 200, and the outer protrusion 1312 may be, but not limited to, a circular protrusion. The inner convex rib 1313 can enhance the contact stress between the locking wing 131 and the plastic-reinforced spiral pipe, and improve the connection stability between the joint body 100 and the plastic-reinforced spiral pipe, and the inner convex rib 1313 may be, but is not limited to, a triangular structure.

Lock nut 200's surface still includes wrench face 220, and wrench face 220 is provided with concave-convex structure 221 for lock nut 200 whole wall thickness is less, has both avoided the product forming process simultaneously, because the surface unevenness that the shrink of nylon part material leads to has strengthened wrench face 220 antiskid requirement again.

The following steps can be adopted during installation:

1. the lock nut 200 is inserted into the plastic rib spiral pipe;

2. sleeving the plastic-rib spiral pipe sleeved with the lock nut 200 into the joint body 100, sleeving the plastic-rib spiral pipe into the bottom of the gap between the joint body 100 and the elastic locking ring 130 as much as possible, and finishing the section of the plastic-rib spiral pipe is not required;

3. the lock nut 200 is screwed into the coupling body 100 along the screw thread until the lower plane of the lock nut 200 is brought into contact with the corresponding plane of the coupling body 100, and the installation is completed.

To sum up, the utility model discloses a to connect the body to set up to 45 arc bending to can be crooked be qualified for the next round of competitions, be suitable for the transform position of being qualified for the next round of competitions, and non-right angle structure also reduces hose connection and bears the side direction shearing force, and the arc is crooked simultaneously makes through wires hole rounding off, thereby makes the threading smooth and easy, prevents that the cable from cutting through, effectively protects the cable.

Moreover, it is to be understood that the described embodiments are merely exemplary of the invention, and are not intended as limiting the scope of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
