Description

Technical Field

[0001] The utility model relates to the technical field of oil injection, in particular to an oil injector with anti-blocking and anti-pollution functions. Background Art

[0002] Oil injection is the name for the surface coating processing of industrial products. Oil injection processing includes plastic oil injection, screen printing, pad printing processing; color changing and screen printing of EVA, rubber and other shoe materials.

[0003] However, in the prior art, the nozzle part of the existing oil injector cannot be protected when not in use, so it is very easy to get dust on it, or it is covered with a nut, which will easily cause the nut to be lost after being removed. In view of the above problems, we have developed an oil injector with anti-blocking and anti-pollution functions. Summary of the Utility Model

[0004] The utility model discloses an oil injector with anti-blocking and anti-pollution functions, aiming to solve the technical problems that the nozzle part of the oil injector cannot be protected when not in use, so it is very easy to get dust on it, or it is covered with a nut, which will easily cause the nut to be lost after being removed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An oil injector with anti-blocking and anti-pollution functions includes a cylinder body. One end of the cylinder body is fixedly connected with a tapered head. The inner wall of the tapered head is equidistantly provided with sliding grooves. The inside of the sliding grooves are all fixedly connected with sliding rods. The outside of the sliding rods are all slidably connected with sliders. The outside of the sliders are all fixedly connected with blocking plates. First springs are fixedly connected between the sliders and the sliding grooves and on the outside of the sliding rods.

[0007] By setting, when oil injection is not carried out, due to the elasticity of the first spring, the slider can be driven to slide on the surface of the sliding rod. Further, the blocking plate can be driven to move during the movement of the slider. Since the sliding grooves inside the tapered head are inclined, multiple blocking plates can approach each other during the movement, so as to close and seal, avoiding contact with dust.

[0008] In a preferred scheme, an oil storage pipe is fixedly connected inside the cylinder body. One end of the oil storage pipe is fixedly connected with a spray head. One end of the oil storage pipe extends to the outside of the cylinder body and is threadedly connected with a nut.

[0009] By setting, after the oil storage pipe is filled with oil for use, oil can be injected through the spray head.

[0010] In a preferred embodiment, blocking rods are slidably connected to the outer side of the conical head at equal intervals. The bottoms of the blocking rods all extend into the corresponding chutes. The tops of the blocking rods are fixedly connected to connecting plates. Second springs are fixedly connected between the connecting plates and the conical head and on the outer sides of the blocking rods. The blocking rods do not contact the first spring.

[0011] By setting, when the slider moves to one side of the blocking rod, due to the elasticity of the second spring, the blocking rod can restrict the slider, so that the nozzle can be used normally.

[0012] In a preferred embodiment, an extrusion rod is slidably connected to one side of the nut. One end of the extrusion rod extends into the oil storage pipe and is fixedly connected to a rubber block. The oil storage pipe is slidably connected to the rubber block.

[0013] By setting, the extrusion rod moves to pressurize the inside of the oil storage pipe.

[0014] In a preferred embodiment, connecting rods are fixedly connected to the outer side of the conical head and at equal intervals on the outer sides of the blocking rods. The connecting rods are all slidably connected to the corresponding connecting plates. The tops of the connecting rods are fixedly connected to limiting plates.

[0015] By setting, as the connecting plate slides between the connecting rods, the limiting plate can limit the connecting plate.

[0016] In a preferred embodiment, two fixed seats are fixedly connected to the outer side of the cylinder body. One end of the extrusion rod is fixedly connected to a push plate.

[0017] By setting, by pushing the push plate, the extrusion rod is driven to move.

[0018] The anti-clogging and anti-pollution injector provided by the present invention has the following advantages:

[0019] First, when no oil is sprayed, due to the elasticity of the first spring, the slider can be driven to slide on the surface of the slide rod. Then, during the movement of the slider, the blocking plate can be driven to move. Since the chute inside the conical head is inclined, multiple blocking plates can approach each other during the movement, so as to close and seal and avoid contacting dust.

[0020] Second, after filling the oil storage pipe with working oil, oil can be sprayed through the nozzle. When the slider moves to one side of the blocking rod, due to the elasticity of the second spring, the blocking rod can restrict the slider, so that the nozzle can be used normally. As the connecting plate slides between the connecting rods, the limiting plate can limit the connecting plate. By pushing the push plate, the extrusion rod is driven to move to pressurize the inside of the oil storage pipe. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Usually, the components of the embodiments of the present application described and marked in the accompanying drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application to be protected, but only represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0027] An anti-clogging and anti-pollution injector disclosed by the present utility model is mainly applied to the scenario where the nozzle part of the injector cannot be protected when not in use, and thus it is extremely easy to get dust on it, or it is covered with a nut, which will easily cause the nut to be lost after being removed.

[0028] Referring to Figure 1 and Figure 2 , an anti-clogging and anti-pollution injector includes a cylinder body 1. One end of the cylinder body 1 is fixedly connected with a conical head 2. The inner wall of the conical head 2 is equidistantly provided with chutes 3. Slide bars 4 are fixedly connected inside the chutes 3. Sliders 5 are slidably connected to the outer sides of the slide bars 4. Blocking plates 7 are fixedly connected to the outer sides of the sliders 5. First springs 6 are fixedly connected between the sliders 5 and the chutes 3 and on the outer sides of the slide bars 4.

[0029] In this embodiment: When fuel injection is not performed, due to the elasticity of the first spring 6, the slider 5 can be driven to slide on the surface of the slide bar 4. Further, during the movement of the slider 5, the blocking plate 7 can be driven to move. Since the chute 3 inside the conical head 2 is inclined, multiple blocking plates 7 can approach each other during the movement, and then close and seal to avoid contact with dust.

[0030] Refer to Figure 1 and Figure 4 In a preferred embodiment, an oil storage pipe 8 is fixedly connected inside the cylinder body 1. One end of the oil storage pipe 8 is fixedly connected with a spray head 9, and one end of the oil storage pipe 8 extends to the outside of the cylinder body 1 and is threadedly connected with a nut 10.

[0031] In this embodiment: After filling the oil storage pipe 8 with the working oil, oil can be sprayed through the spray head 9.

[0032] Refer to Figure 1 and Figure 3 In a preferred embodiment, blocking rods 13 are slidably connected to the outside of the conical head 2 at equal intervals. The bottoms of the blocking rods 13 all extend into the corresponding chutes 3. Connecting plates 14 are fixedly connected to the tops of the blocking rods 13. Second springs 17 are fixedly connected between the connecting plates 14 and the conical head 2 and on the outside of the blocking rods 13. The blocking rods 13 do not contact the first spring 6.

[0033] In this embodiment: When the slider 5 moves to one side of the blocking rod 13, due to the elasticity of the second spring 17, the blocking rod 13 can restrict the slider 5, so that the spray head 9 can be used normally.

[0034] Refer to Figure 1 and Figure 2 In a preferred embodiment, a pressing rod 11 is slidably connected to one side of the nut 10. One end of the pressing rod 11 extends into the oil storage pipe 8 and is fixedly connected with a rubber block. The oil storage pipe 8 is slidably connected with the rubber block.

[0035] In this embodiment: The pressing rod 11 moves to pressurize the inside of the oil storage pipe 8.

[0036] Refer to Figure 1 and Figure 3 In a preferred embodiment, connecting rods 15 are fixedly connected to the outside of the conical head 2 and at equal intervals on the outside of the blocking rods 13. The connecting rods 15 are all slidably connected with the corresponding connecting plates 14. Limiting plates 16 are fixedly connected to the tops of the connecting rods 15.

[0037] In this embodiment: By sliding the connecting plate 14 between the connecting rods 15, the limiting plate 16 can limit the connecting plate 14.

[0038] Referring to Figure 1 and Figure 4 In a preferred embodiment, two fixing seats 18 are fixedly connected to the outer side of the cylinder body 1, and a push plate 12 is fixedly connected to one end of the extrusion rod 11.

[0039] In this embodiment: By pushing the push plate 12, the extrusion rod 11 is driven to move.

[0040] Working principle: When in use, when oil spraying is not performed, due to the elasticity of the first spring 6, the slider 5 can be driven to slide on the surface of the sliding rod 4. Further, during the movement of the slider 5, the blocking plate 7 can be driven to move. Since the chute 3 inside the conical head 2 is inclined, a plurality of blocking plates 7 can approach each other during the movement, and then close and seal to avoid contact with dust;

[0041] After filling the oil storage pipe 8 with the oil for use, oil can be sprayed through the nozzle 9. When the slider 5 moves to one side of the blocking rod 13, due to the elasticity of the second spring 17, the blocking rod 13 can limit the slider 5, so that the nozzle 9 can be used normally. By sliding the connecting plate 14 between the connecting rods 15, the limiting plate 16 can limit the connecting plate 14. By pushing the push plate 12, the extrusion rod 11 is driven to move, so as to pressurize the inside of the oil storage pipe 8.

[0042] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. The substitution may be the substitution of part of the structure, device, and method steps, or a complete technical solution. Any equivalent substitution or change made according to the technical solution and the inventive concept of the present invention should be covered within the protection scope of the present invention.
