Description

Technical Field

[0001] The utility model relates to the field of windshield wiper water spray nozzles, and more specifically, to an automobile plastic water spray nozzle. Background Art

[0002] When the car wiper cleans the windshield, the water nozzle installed on the car hood sprays water on the glass, and then the wiper wipes back and forth to clean the glass. Traditional car wiper water nozzles are generally arranged with two, which are set at different positions under the glass, so that the glass water can be evenly sprayed on the windshield.

[0003] Although the existing installation structure of the automobile water spray nozzle is relatively strong, it still has the following shortcomings when disassembling:

[0004] 1. The connecting pipe at the bottom of the existing water spray nozzle is usually fixedly connected with 2-4 expansion claws, and the top of the expansion claw is usually in an outward expansion form. Although such a structural form is convenient for inserting and fixing inside the hood hole, it is not conducive to pulling out from the outside of the hood during disassembly, and the expansion claw at the bottom of the water spray nozzle is often easily damaged, which affects the service life;

[0005] 2. The connecting pipe at the bottom of the existing water spray nozzle is usually directly inserted into the water spray hose. When the reserved length of the water spray hose is not long enough, it is easy for the water spray hose to fall into the hood hole when the water spray nozzle is pulled out, which is not conducive to the subsequent reconnection of the water spray hose;

[0006] So we proposed a car plastic water spray nozzle to solve the above problems. Utility Model Content

[0007] 1. Technical issues to be solved

[0008] In view of the problems existing in the prior art, the purpose of the utility model is to provide a plastic automobile water spray nozzle, which firstly lengthens the top of the expansion claw so that the top of the expansion claw penetrates and extends to the outside of the upper cover, so that when the water spray nozzle needs to be unplugged, it is only necessary to pinch the tops of the two expansion claws and bring the outer expansion parts of the bottoms of the two expansion claws together, and then the nozzle can be easily taken out from the inside of the engine hood hole, thereby improving the convenience of disassembly and assembly while reducing the probability of damage to the nozzle during later disassembly and assembly of the nozzle, thereby increasing the service life; and at the end of the connecting pipe, not only a group of limiting convex edges are provided to limit the connected water inlet hose, but also a group of anti-drop pins are provided to be inserted into the inner wall of the end of the water inlet hose, and the double structure reduces the probability of the water inlet hose falling off due to pulling force in the later stage, thereby facilitating the later installation work.

[0009] 2. Technical solution

[0010] To solve the above problems, the utility model adopts the following technical solutions.

[0011] A plastic automobile water spray nozzle comprises a spray head, wherein a connecting pipe is fixedly connected to the bottom of the spray head, an upper cover is fixedly mounted on the base at the bottom of the spray head, and a water spray hole is arranged on the top of the spray head, and the water spray hole penetrates to the outside of the upper cover, expansion claws are fixedly connected to the outer wall of the connecting pipe on both sides, the tops of the two expansion claws penetrate the base at the bottom of the spray head and the side wall of the upper cover in turn, and the tops of the two expansion claws extend to the outside of the side wall of the upper cover, an inlet hose is sleeved on the outer side of the end of the connecting pipe, a group of limiting convex edges are fixedly connected to the end of the connecting pipe located inside the water inlet hose, and a hose clamp is fixedly mounted on the outer side of the water inlet hose located between the group of limiting convex edges.

[0012] Furthermore, the nozzle, the connecting pipe and the two expansion claws are a polyhedron structure integrally injection-molded from a plastic material, and the outer walls of the nozzle and the connecting pipe are smooth and free of burrs.

[0013] Furthermore, the outer wall diameter of a group of the limiting flanges is larger than the outer wall diameter of the connecting pipe, and a reducing plug portion is further provided at the end of the connecting pipe.

[0014] Furthermore, a group of anti-dropout pins are fixedly welded on the outer wall of the connecting tube between the expansion claw and a group of the limiting convex edges, and the tops of the group of anti-dropout pins are all bent toward the direction of the expansion claw.

[0015] Furthermore, a contraction groove is provided on the bottom base of the nozzle at the connection between the expansion claw and the bottom base of the nozzle, and the width of the contraction groove is greater than the thickness of the expansion claw.

[0016] 3. Beneficial effects

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] (1) In this solution, the top of the expansion claw is lengthened so that the top of the expansion claw passes through and extends to the outside of the upper cover, so that when the water nozzle needs to be unplugged, it is only necessary to pinch the top of the two expansion claws and bring the outer expansion parts of the bottom of the two expansion claws together. At this time, the nozzle can be easily taken out from the inside of the engine cover hole, which improves the convenience of disassembly and assembly while reducing the probability of damage to the nozzle during later disassembly and assembly, thereby increasing the service life;

[0019] (2) In this solution, not only a set of limiting convex edges are provided at the end of the connecting pipe to limit the connected water inlet hose, but also a set of anti-drop pins are provided that can be inserted into the inner wall of the end of the water inlet hose. The double structure reduces the probability of the water inlet hose falling off due to pulling force in the later stage, thereby facilitating the later installation work.

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention specification; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments of the present invention are within the scope of protection of the present invention.

[0027] Embodiment 1:

[0028] See also Figure 1-Figure 4 A plastic water spray nozzle for automobiles comprises a spray head 1, a connecting pipe 2 is fixedly connected to the bottom of the spray head 1, an upper cover 3 is fixedly installed on the base at the bottom of the spray head 1, and a water spray hole 101 is arranged on the top of the spray head 1, and the water spray hole 101 penetrates to the outside of the upper cover 3, expansion claws 4 are fixedly connected to the outer wall of the connecting pipe 2 on both sides, the tops of the two expansion claws 4 penetrate the base at the bottom of the spray head 1 and the side wall of the upper cover 3 in turn, and the tops of the two expansion claws 4 extend to the outside of the side wall of the upper cover 3, a water inlet hose 5 is sleeved on the outer side of the end of the connecting pipe 2, a group of limiting convex edges 6 are fixedly connected to the end of the connecting pipe 2 located inside the water inlet hose 5, and a hose clamp 7 is fixedly installed on the outer side of the water inlet hose 5 located between the group of limiting convex edges 6;

[0029] A group of anti-dropout pins 8 are fixedly welded on the outer wall of the connecting tube 2 between the expansion claw 4 and a group of limiting convex edges 6, and the tops of the group of anti-dropout pins 8 are bent toward the expansion claw 4. A contraction groove 102 is opened on the bottom base of the nozzle 1 at the connection between the expansion claw 4 and the bottom base of the nozzle 1, and the width of the contraction groove 102 is greater than the thickness of the expansion claw 4.

[0030] The operating principle of this kind of automobile plastic water spray nozzle is:

[0031] First, pull the water inlet hose 5 out from the hole inside the car hood, and then insert the end of the water inlet hose 5 into the bottom of the connecting pipe 2 through the reducer plug until the inserted end reaches the bend of the connecting pipe 2, and then pull the water inlet hose 5 in the opposite direction, so that a group of anti-dropping pins 8 can be inserted from the inner wall of the water inlet hose 5 to the outside, so as to achieve the effect of fixing and limiting the end of the water inlet hose 5, and then install the hose clamp 7 on the outside of the water inlet hose 5 between a group of limiting convex edges 6, so as to further achieve the effect of preventing the water inlet hose 5 from dropping out and fixing in the later stage, and finally hold the head of the top of the nozzle 1 to insert the connecting pipe 2 into the hole inside the car hood, and the two expansion claws 4 in the outward expansion form can achieve the effect of supporting and limiting the connection;

[0032] When the cover nozzle needs to be removed, one only needs to first pinch the tops of the expansion claws 4 on both sides of the upper cover 3 to force the two expansion claws 4 to move closer to each other. At this time, the outer expansion surfaces of the tops of the two expansion claws 4 can be reduced, so that the two expansion claws 4 of the nozzle can be smoothly pulled out from the hole inside the car hood. The operation is simple.

[0033] Embodiment 2:

[0034] In view of the above embodiment 1, for further description, refer to Figure 2 and Figure 4 The nozzle 1, the connecting pipe 2 and the two expansion claws 4 are a polyhedron structure integrally injection-molded by a plastic material, and the outer walls of the nozzle 1 and the connecting pipe 2 are smooth and free of burrs. The outer wall diameter of a set of limiting convex edges 6 is larger than the outer wall diameter of the connecting pipe 2.

A contraction groove is provided on the bottom base of the nozzle 1 at the connection between the expansion claw 4 and the bottom base of the nozzle 1, and the width of the contraction groove is greater than the thickness of the expansion claw 4.

[0035] The nozzle 1, the connecting pipe 2 and the two expansion claws 4 are a polyhedron structure integrally injection-molded from a plastic material, with a better degree of structural integration and a stronger structural strength. The arrangement of the reducer plug portion facilitates smooth insertion of the end of the water inlet hose 5, and the opening of the contraction groove facilitates pinching the top of the expansion claw 4 so that the expansion claw 4 can be smoothly offset to the connecting pipe 2 to avoid interference.

[0036] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto.
