Abstract
A clamping water-feeding plug is characterized by comprising a body, a plate rib and outer threads are arranged on the outer wall of the body, a step and a location rib are arranged on the inner wall of the body, and the step is contacted with one side of a sealing ring, and the other side of the sealing ring is contacted with one end of a pressing ring. The outer threads are matched with inner threads of a clamping nut, a casing coupling is arranged in the clamping nut, an opening fastening ring is arranged in the casing coupling, and a clamping rib is arranged in the opening fastening ring. The clamping rib and the sealing ring are matched with the outer wall of a water pipe, the end portion of the casing coupling and the flanging of the opening fastening ring are contacted with the other end of the pressing ring. The clamping water-feeding plug is convenient to operate, saves labor in construction, and has good sealing effect.
Description
Technical field
The utility model relates to water blocking head on the banding formula, belongs to the water channel pipe fitting.
Background technique
Water supply line need adopt corresponding plug to the head shutoff of water pipe after arriving the end.Existing water blocking head inwall or the outer wall direct and water pipe gone up is tightly connected, and uses screw-thread fit usually, like this will be to the head system screw thread of water pipe, and not only construction trouble, and also existing plastic water pipe is difficult to processing, the while poor sealing performance.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming that prior art exists, a kind of plastic water pipe or metallic water pipe of being applicable to be provided, and the head of water pipe is not needed to process separately, and installation and removal are laborsaving, convenient, water blocking head on the banding formula of good sealing effect.
The technological scheme of water blocking head is on the utility model banding formula: it is characterized in that comprising body, the outer wall of body is shaped on plate muscle and outside thread, and the inwall of body is shaped on step and positioning bar; Step contacts with a side of seal ring; One of the opposite side of seal ring and retainer ring contacts, and outside thread matches with the internal thread of banding nut, is shaped on casing coupling in the banding nut; Construction opening retaining ring in the casing coupling; Be shaped on the card muscle in the opening retaining ring, card muscle and seal ring match with pipe outer wall, and turning edge of casing coupling end and opening retaining ring contacts with the other end of retainer ring.
The utility model discloses water blocking head on a kind of banding formula, at first the opening retaining ring is put in the banding nut during installation, and be enclosed within outside the water pipe together; Be put into seal ring and reach the step place in the body, retainer ring inserts in the body again, and good and sound successively retainer ring, seal ring and body is set to outside the water pipe; When making the head of water pipe reach intrinsic positioning bar; The internal thread of banding nut and the outside thread of body are screwed again, made the casing coupling of banding nut promote of retainer ring, the other end of retainer ring is to seal ring extrusion-deformation; Arrive the sealing purpose of seal ring and pipe outer wall, the opening retaining ring is to the pipe outer wall banding simultaneously.Adopt this plug easy to operate, it is laborsaving to construct, good sealing effect.
Water blocking head on the utility model banding formula, the outer wall of described banding nut is shaped on convex tendon.Convex tendon good hand touch when fastening nut has been arranged, held tightly, and improved fastness.The inner thread mouth of said banding nut is shaped on air vent.There has been air vent lighter when fastening nut.
Description of drawings
Fig. 1 is the structural representation of water blocking head on the utility model banding formula.
Embodiment
The utility model relates to water blocking head on a kind of banding formula, and is as shown in Figure 1, it is characterized in that comprising body 1; The outer wall of body is shaped on plate muscle 11 and outside thread 12, and the inwall of body is shaped on step 13 and positioning bar 15, and step contacts with a side of seal ring 2; One of the opposite side of seal ring and retainer ring 3 contacts, and outside thread 12 matches with the internal thread 45 of banding nut 4, is shaped on casing coupling 41 in the banding nut 4; Construction opening retaining ring 5 in the casing coupling; Be shaped on card muscle 51 in the opening retaining ring 5, card muscle 51 matches with pipe outer wall with seal ring 2, and turning edge of casing coupling 41 ends 42 and opening retaining ring 5 52 contacts with the other end of retainer ring 3.At first opening retaining ring 5 is put in the banding nut 4 during installation, and is enclosed within together outside the water pipe, be put into seal ring 2 again and reach step 13 places in the body 1; Retainer ring 3 one inserts in the body 1 again; And will be successively good and sound retainer ring 3, seal ring 2 and body 1 be set to outside the water pipe, when making the head of water pipe reach intrinsic positioning bar 15, the internal thread 45 of banding nut 4 screwed with the outside thread 12 of body 1 again; Make the casing coupling 41 of banding nut promote of retainer rings 3; The other end of retainer ring arrives the sealing purpose of seal ring and pipe outer wall to seal ring 2 extrusion-deformations, simultaneously 5 pairs of pipe outer wall bandings of opening retaining ring.Adopt this plug easy to operate, it is laborsaving to construct, good sealing effect.The outer wall of described banding nut 4 is shaped on convex tendon 43.Convex tendon 43 good hand touch when fastening nut has been arranged, held tightly, and improved fastness.The internal thread of said banding nut 4 is shaped on air vent 46 for 45 mouthfuls.There has been air vent 46 lighter when fastening nut.
