Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1 to 3, the preferred embodiment of the present invention is a clamping and pressing type connector, which includes a body 1, a pressing sleeve 2, a retainer ring 3 and a sealing ring 4, wherein an insertion portion 5 is disposed on the body 1, the pressing sleeve 2 is sleeved on the insertion portion 5 and forms a space for inserting a pipeline with the insertion portion 5, the retainer ring 3 is disposed at a root portion 6 of the insertion portion 5 and is respectively connected with the insertion portion 5 and the pressing sleeve 2, a peripheral ring of the insertion portion 5 is provided with three sealing grooves 7, a first square tooth 8 and at least two first inverted teeth 9 are disposed between the adjacent sealing grooves 7 in sequence from an outer end of the insertion portion 5 to the root portion 6 of the insertion portion 5, and the sealing ring 4 is three and is disposed in the three sealing grooves 7.
Therefore, insert the pipeline in compressing tightly the space between cover 2 and the inserted part 5 during the use, then use U type snap ring 10, or H type snap ring 11, or TH type snap ring 12, or RFZ type snap ring 13 joint on compressing tightly cover 2, the snap ring can be through compressing tightly cover 2 with the pipeline extrusion to sealing washer 4, the annular tooth homoenergetic of snap ring and the sealing washer 4 phase-match of inserted part 5 to reach sealed effect.
In the specific embodiment, as shown in fig. 4 to 7, when the U-shaped snap ring 10 is used for clamping and pressing the present invention, two positions of the three annular teeth 101 on the U-shaped snap ring 10 are opposite to or close to the sealing ring 4, so that the three sealing rings 4 are all in the extruded state, thereby achieving the sealing effect; when the H-shaped snap ring 11 is used for clamping and pressing the utility model, two positions which are over against or close to the sealing ring 4 are arranged in the three annular teeth 111 on the H-shaped snap ring 11, so that the three sealing rings 4 are all in an extruded state, thereby achieving the sealing effect; when the utility model is clamped and pressed by the TH-shaped clamp ring 12, the annular teeth 121 on the TH-shaped clamp ring 12, which are close to the root 6 of the inserting part 4, are over against the sealing ring 4 close to the root 6 of the inserting part 4, so that the sealing ring 4 can be in an extruded state, thereby achieving the sealing effect; use RFZ type snap ring 13 card to press the utility model discloses the time, the whole card of the interior annular surface 131 of RFZ type snap ring is pressed on compressing tightly cover 2, can make three sealing washer 4 all be in by the extruded state to reach sealed effect. Specifically, the first undercut 9 is provided with a guide slope and a stop vertical surface facing the root 6 of the insertion portion 5.
It can be seen that, the utility model discloses can with the pipe connection and reach the effect of leak protection crimping, have good sealing performance to, the structure of insertion portion 5 can both the phase-match with the annular tooth on the various snap rings, consequently the utility model discloses a card pressure formula attach fitting can be applicable to the card pressure instrument of various specific types, and application scope is wide, satisfies different card pressure demands. The utility model has the advantages of convenient operation is simple and easy, realizes sealed leak protection, can use the snap ring of different grade type, and application scope is wide.
For example, a second square tooth 14 and a third square tooth 15 are annularly arranged between the root 6 of the insertion portion 5 and the sealing groove 7 close to the root 6 of the insertion portion 5, the second square tooth 14 is adjacent to the sealing groove 7 close to the root 6 of the insertion portion 5, a first wide groove 16 is formed between the second square tooth 14 and the third square tooth 15, and a second wide groove 17 is formed between the third square tooth 15 and the root 6 of the insertion portion 5.
Illustratively, the outer end of the insertion part 5 is provided with a conical surface 18, and a second back-off tooth 19 is arranged between the outer end of the insertion part 5 and the sealing groove 7 close to the outer end of the insertion part 5. Specifically, the second undercut 19 is provided with a guide slope and a stop vertical surface facing the root 6 of the insertion portion 5. With such a design, the pipe can be inserted more smoothly and quickly, the pipe can be prevented from easily falling off, and the water flow can be prevented from flowing back between the pipe and the insertion portion 5, thereby further preventing the water flow from leaking.
For example, in order to make the pipe fit with the insert part 5 more tightly, the sides of the three sealing grooves 7 close to the outer end of the insert part 5 are provided with square notches 20.
Illustratively, the retainer ring 3 is provided with a viewing hole 33. As shown in fig. 8, when the whole pipe system is connected, a constructor needs to test the pipe system through water and pressure, if a non-crimped connector is present in the pipe system, water can rapidly flow out from the observation hole 33 of the retainer ring 3, so that the constructor can easily find the connector, and the quick leak detection is realized, so as to achieve the function of pre-leak-proof crimping.
Illustratively, the root 6 of the insertion portion 5 is provided with an annular groove 21, one end of the retainer ring 3 is provided with a ring buckle 31, the ring buckle 31 is connected to the annular groove 21, the other end of the retainer ring 3 is provided with a groove 32, the compression sleeve 2 is connected to the groove 32, and the observation hole 33 is arranged between the ring buckle 31 and the groove 32. With such a design, the pressing sleeve 2 and the body 1 can be better connected, water leakage can be further prevented, and the sealing performance is improved.
Illustratively, the outer end and the root 6 of the pressing sleeve 2 are turned outwards, and the flanging 22 at the root 6 of the pressing sleeve 2 is clamped in the groove 32, so that the pressing sleeve 2 and the retainer ring 3 can be better connected, and the flanging 22 of the pressing sleeve 2 can effectively prevent water from leaking between the pressing sleeve 2 and the retainer ring 3, further improving the sealing performance and preventing water leakage.
For example, in order to tightly connect the sealing ring 4 to the insert part 5, the maximum outer diameter of the sealing ring 4 is smaller than or equal to the maximum outer diameter of the insert part 5. Such design, when connector does not carry out the crimping, hydroenergy flows out from observation hole 33 through the space of pipeline with portion of inserting 5 more easily, makes the connector department of leaking the crimping realize leaking fast to make constructor can discover the connector of leaking the crimping fast when the pressure testing detects, improve the efficiency of construction, improve factor of safety.
The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the invention, therefore, the invention is not limited thereto.
