Description

Technical Field

[0001] This utility model relates to the field of BDP oil spray gun technology, specifically to a spray gun device for uniform spraying. Background Technology

[0002] BDP oil is an industrial flame-retardant oil with excellent flame-retardant properties, high thermal stability, and good hydrolytic stability. It is usually applied to lubrication points, gearboxes, bearings, and other locations in equipment via an oil gun. However, during the use of BDP oil guns, it is necessary to connect with an external delivery pipe. If the connection process is slow, it will affect the work efficiency of the staff. To overcome this defect, existing technology 1 (Chinese patent application No. 202421554312.2, application date 2024-07-03) is a grease gun pressure testing machine. During use, a robotic arm inserts the nozzle of the grease gun into a flared fitting. When there is a slight difference between the flared fitting and the grease gun nozzle, the grease gun nozzle acts on the flared fitting, causing the flared fitting to move along the guide platform, so that the flared fitting automatically corrects its position, facilitating the connection between the grease gun nozzle and the flared fitting.

[0003] After prolonged use, the nozzle connection point may become stuck due to residual oil or impurities. The device in the aforementioned application lacks a disassembly aid, which hinders the disassembly process and causes unnecessary trouble for the workers. Utility Model Content

[0004] The purpose of this utility model is to provide a spray gun device that can spray evenly, so as to solve the problem mentioned in the background art that the lack of a structure to assist in disassembly during use affects the disassembly process of the oil gun and causes unnecessary trouble for the workers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spray gun device for uniform spraying, comprising a spray gun barrel and a connecting pipe, wherein a nozzle is provided at the left end of the spray gun barrel, and a handle is provided on the surface of the spray gun barrel, and a connecting pipe is provided at the right end of the spray gun barrel; an external connecting plate is fixedly connected to the surface of the connecting pipe; the external connecting plate is engaged with the surface of the connecting pipe, and the end of the external connecting plate is connected to the output end of an external feeding device through an external flexible hose; a push rod is slidably provided inside the external connecting plate.

[0006] Preferably, the surface of the outer plate has through holes, and the surface of the connecting pipe is fixedly connected with long pins, which are symmetrically distributed on both sides of the connecting pipe, and each long pin corresponds to one of the through holes.

[0007] Preferably, a limiting plate is fixedly connected to the back of the outer plate, and a locking block is slidably arranged inside the limiting plate, with the inner side of the locking block being inclined, and a locking groove is formed on the surface of the long pin.

[0008] Preferably, an auxiliary plate is fixedly connected to the surface of the card block, and a first spring is fixedly connected to the surface of the auxiliary plate, and the other side of the first spring is fixedly connected to the inner wall of the limiting plate.

[0009] Preferably, a long rod is fixedly connected to the end of the card block.

[0010] Preferably, the surface of the push rod is in contact with the inner wall of the outer plate, and the push rods are symmetrically distributed on both sides of the outer plate.

[0011] Preferably, a second spring is fixedly connected to the surface of the push rod, and the other side of the second spring is fixedly connected to the inner wall of the outer plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the spray gun device for uniform spraying adopts a novel structural design, the specific details of which are as follows:

[0013] (1) In the process of connecting the pipe, the push rod inside the outer plate of the spray gun device with uniform spraying will be pushed by the connecting pipe during the connection process. The push rod moves in the direction of squeezing the second spring. That is, after the connecting pipe and the outer plate are connected, the push rod will keep squeezing the second spring. After the end of the locking block moves out of the slot, the push rod will push the connecting pipe under the action of the second spring, so that the connecting pipe will quickly disengage and there will be no jamming.

[0014] Furthermore, the nozzle at the end of the spray gun can atomize the flame-retardant oil into micron-sized droplets, improving the uniformity of coverage (particle size is usually 20μm~50μm), achieving the function of uniform spraying, and controlling the spraying pressure (usually 0.3MPa~0.6MPa) to adapt to flame-retardant oils of different viscosities, thus improving flexibility.

[0015] (2) When the spray gun device with uniform spraying needs to be removed for maintenance after a long period of use, the long rod can be pulled directly to move the end of the clamping block out of the slot. At this time, the connecting pipe and the outer plate are not in a locked state with the connecting pipe, and the connecting pipe can be removed.

[0016] (3) The spray gun device with uniform spraying, when it is necessary to connect the external pipe during use, insert the long pin into the through hole. At this time, the long pin will push the inclined surface of the locking block, so that the locking block and the auxiliary plate move in the direction of squeezing the first spring. After the surface of the external plate contacts the connecting pipe, the locking block and the locking groove are in the same horizontal direction. At this time, the locking block enters the locking groove under the action of the first spring, that is, the connecting pipe has been installed on the external plate. The operation process is quick and convenient.

[0017] Furthermore, the locking blocks and slots are distributed on both sides of the connecting tube, which optimizes the locking effect. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides the following technical solution: a spray gun device for uniform spraying.

[0027] Example 1: The locking block 12 and locking slot 9 allow for quick engagement of the connecting pipe 5 and connecting tube 4, as shown below. Figures 1-5As shown, the device includes a spray gun barrel 1 and a connecting pipe 5. A nozzle 3 is provided at the left end of the spray gun barrel 1, and a handle 2 is provided on the surface of the spray gun barrel 1. A connecting pipe 4 is provided at the right end of the spray gun barrel 1. An external connecting plate 6 is fixedly connected to the surface of the connecting pipe 5. The external connecting plate 6 is snapped onto the surface of the connecting pipe 4, and the end of the external connecting plate 6 is connected to the output end of an external feeding device through an external flexible hose. A through hole 7 is opened on the surface of the external connecting plate 6, and a long pin 8 is fixedly connected to the surface of the connecting pipe 4. The long pins 8 are symmetrically distributed on both sides of the connecting pipe 4, and the long pins 8 correspond one-to-one with the through holes 7.

[0028] The back of the outer plate 6 is fixedly connected to the limiting plate 10, and the limiting plate 10 is slidably provided with a locking block 12. The inner side of the locking block 12 is inclined. The surface of the long pin 8 is provided with a locking groove 9. The surface of the locking block 12 is fixedly connected to the auxiliary plate 13, and the surface of the auxiliary plate 13 is fixedly connected to the first spring 14. The other side of the first spring 14 is fixedly connected to the inner wall of the limiting plate 10.

[0029] When connecting pipe 4 and pipe 5, such as Figure 3 As shown, insert the connecting pipe 5 and the outer plate 6 into the interior of the connecting pipe 4. At this time, the long pin 8 will enter the interior of the through hole 7, and the inclined surface of the locking block 12 will be pushed. At this time, the auxiliary plate 13 moves in the direction of compressing the first spring 14 (as shown). Figure 4 As shown), after the surface of the outer plate 6 contacts the surface of the connecting pipe 4, the locking block 12 and the locking groove 9 are in the same horizontal direction. At this time, the locking block 12 enters the interior of the locking groove 9 under the action of the first spring 14 and the auxiliary plate 13, that is, the connecting pipe 5 and the outer plate 6 have been installed on the connecting pipe 4, and the operation process is quick and convenient.

[0030] Example 2: Unlike Example 1, the long rod 11 allows the end of the locking block 12 to be quickly moved out of the slot 9, as shown below. Figure 4 As shown, a long rod 11 is fixedly connected to the end of the locking block 12. When it is necessary to remove the outer plate 6 and the connecting pipe 5, the long rod 11 is pulled, and the long rod 11 drives the end of the locking block 12 to move out of the slot 9. At this time, the outer plate 6 and the connecting pipe 5 are not in a locked state with the connecting pipe 4, and the outer plate 6 and the connecting pipe 5 can be pulled out.

[0031] Example 3: Unlike Example 1, the connecting pipe 4 and the coupling pipe 5 can be quickly separated by the push rod 15 and the second spring 16, as shown below. Figure 6 As shown, a push rod 15 is slidably disposed inside the outer plate 6. The surface of the push rod 15 is in contact with the inner wall of the outer plate 6, and the push rod 15 is symmetrically distributed on both sides of the outer plate 6. A second spring 16 is fixedly connected to the surface of the push rod 15, and the other side of the second spring 16 is fixedly connected to the inner wall of the outer plate 6.

[0032] like Figure 6 As shown, the end of the push rod 15 is connected to the second spring 16. Therefore, during the docking process of the connecting pipe 5, the push rod 15 inside the outer plate 6 will be pushed by the connecting pipe 4. The push rod 15 moves in the direction of squeezing the second spring 16. That is, after the connecting pipe 5 and the outer plate 6 are docked, the push rod 15 keeps squeezing the second spring 16. After the end of the locking block 12 moves out of the locking groove 9, the push rod 15 will push the connecting pipe 4 under the action of the second spring 16, so that the connecting pipe 4 can be quickly disengaged without jamming.

[0033] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
