Description

Technical Field

[0001] The utility model relates to the technical field of dust blowing protection, in particular to an openable and closable pneumatic dust blowing gun protective cover. Background Art

[0002] Machining is a common process in the workpiece processing. During the machining process, although the chip removal structure of the tool can take a large amount of machining debris out of the workpiece, it will still remain on the work surface or in the hole of the workpiece. These debris not only affect the subsequent processing operations, but also easily cause injuries to workers. Moreover, the debris left in the hole affects the cleaning of the workpiece and also brings inconvenience to the use and assembly of the processed objects. In addition, even in the non-drilling processing, manufacturing and maintenance process, machining debris often falls into the hole of the workpiece, causing many inconveniences in use. Therefore, during the processing, manufacturing and maintenance process, we must clean the debris in the hole in time.

[0003] Patent CN202120555323.2 discloses a protective device for cleaning a dust blower gun. By passing the hard tube through the second clamping hole on the locking block and the first clamping hole on the wind shield, the hard tube can be clamped by the rebound force of the spring. When disassembling, you only need to press the locking block to enlarge the hole formed between the second clamping hole and the first clamping hole to pull out the hard tube. The disassembly and assembly are very convenient. Through the wind shield and the inner cavity surface set on the inside of the wind shield, dust and debris will not be splashed by high-pressure gas to injure the operator when cleaning. The wind shield can effectively block dust and debris, greatly improving the safety of the operator when blowing dust.

[0004] However, after using the fixed wind shield, when the dust blower needs to be hung on the wall, it is difficult to hang the dust blower together with the wind shield on the wall due to the large cross-section of the wind shield. The locking block needs to be frequently pressed to remove the wind shield from the dust blower, which is troublesome to install during use. Utility Model Content

[0050] The following describes exemplary embodiments of the present invention in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0051] like Figures 1 to 2As shown, an embodiment of the present invention provides an openable and closable pneumatic dust blow gun protective cover, comprising: a spray gun 1, a gun rod 101; further comprising: a sliding member sliding on the gun rod 101; a plurality of groups of umbrella rib rods 402, wherein the plurality of groups of umbrella rib rods 402 are connected to the sliding member via connecting members, and the sliding member drives the umbrella rib rods 402 to open and close; a flexible transparent umbrella cover 406 connected to two adjacent umbrella rib rods 402, and opens and closes simultaneously with the umbrella rib rods 402; a driving member provided on the sliding member to drive the sliding member to slide; and a clamping member provided on the sliding member to keep the umbrella rib rods 402 and the flexible transparent umbrella cover 406 open and closed.

[0052] In an embodiment of the present invention, a sliding member is provided, and the umbrella rib rod 402 is driven to rotate by sliding the sliding member, thereby driving the umbrella rib rod 402 to rotate around one end, so that several umbrella rib rods 402 are rotated at a certain angle at the same time, thereby making the flexible transparent umbrella surface 406 open or retracted; when working, the flexible transparent umbrella surface 406 is opened to effectively prevent debris from splashing; when not working, the sliding member is slid in the opposite direction to retract the flexible transparent umbrella surface 406, thereby making it convenient to hang the spray gun 1 on the wall.

[0053] like Figures 1 to 8 As shown, the sliding member includes: a connecting sleeve 202, which is sleeved on the gun barrel 101; a first placement groove 203, which is opened on the connecting sleeve 202; a fixed sleeve 204, which is sleeved on the gun barrel 101 and is located at one end of the connecting sleeve 202; a second placement groove 205, which is opened on the fixed sleeve 204; a connecting spring 206, one end of which is set in the first placement groove 203 and the other end is set in the second placement groove 205, so as to connect the connecting sleeve 202 and the fixed sleeve 204 together.

[0054] In the embodiment of the present invention, when the dustproof device is placed as a whole on the spray gun 1, the connecting sleeve 202 is first sleeved on the gun barrel 101, and then the fixed sleeve 204 is driven to be sleeved on the gun barrel 101 together. The connection between the fixed sleeve 204 and the gun barrel 101 is designed to be made of rubber elastic material, so that when the fixed sleeve 204 is sleeved on the gun barrel 101, the elastic force is large and it will not slide easily on the gun barrel 101. A connecting spring 206 is provided to connect the connecting sleeve 202 and the fixed sleeve 204 together, so that the connecting sleeve 202 and the fixed sleeve 204 are bounced a certain distance under the action of the connecting spring 206; thereby facilitating manual control of the sliding of the connecting sleeve 202 on the gun barrel 101.

[0055] like Figures 1 to 8As shown, the connecting member includes: a rotating connecting member, which is provided on the connecting sleeve 202 and is rotatably connected to one end of the umbrella rib rod 402 to drive the umbrella rib rod 402 to rotate; a limiting connecting member, which is provided on the fixing sleeve 204 and is slidably connected to one end of the umbrella rib rod 402 to limit the rotation angle of the umbrella rib rod 402.

[0056] like Figures 1 to 8 As shown, the rotating connecting member includes: connecting ears 401, which are provided in several groups. Several groups of connecting ears 401 are evenly arranged on the circumference of the connecting sleeve 202, and several groups of connecting ears 401 correspond one-to-one with several groups of umbrella rib rods 402, and the other end of the connecting ear 401 is rotatably connected to the other end of the umbrella rib rod 402.

[0057] like Figures 1 to 8 As shown, the limiting connector includes: a limiting rod 403, which is provided in several groups. The limiting rods 403 of the several groups are evenly arranged on the circumference of the fixing sleeve 204, and the several groups of limiting rods 403 correspond one-to-one to the several groups of umbrella rib rods 402; a sliding groove 404, which is opened at one end of the umbrella rib rod 402, and the other end of the limiting rod 403 slides in the sliding groove 404; a second clamping rod 405, which is connected to the other end of the limiting rod 403 and slides in the sliding groove 404 to prevent the limiting rod 403 from moving out of the sliding groove 404.

[0058] In the embodiment of the present utility model, the driving member drives the connecting sleeve 202 to slide along the gun barrel 101 toward the fixed sleeve 204, thereby driving the connecting ear 401 on the connecting sleeve 202 to slide toward the fixed sleeve 204. At the same time, the limiting rod 403 moves along the sliding groove 404 on the rib rod 402 toward the direction away from the connecting ear 401. The rib rod 402 is limited by the connecting ear 401 and the limiting rod 403, thereby rotating the rib rod 402 around the end close to the connecting ear 401. The closer the connecting sleeve 202 is to the fixed sleeve 204, the greater the angle of rotation of the rib rod 402.

[0059] At the same time, the connecting sleeve 202 moves, driving the connecting spring 206 to contract and move to a certain position. Under the restriction of the clamping part, the connecting sleeve 202 and the fixed sleeve 204 remain relatively stationary, thereby completing the opening of the umbrella rib rod 402, thereby driving the flexible transparent umbrella cover 406 to open, meeting the requirements during work.

[0060] like Figures 1 to 8 As shown, the driving member includes: a driving sleeve 201 connected to the connecting sleeve 202; and a driving block 207 provided on the driving sleeve 201.

[0061] In an embodiment of the present utility model, the driving sleeve 201 is fixedly connected to the connecting sleeve 202, and the driving sleeve 201 is driven to move by manually pushing the driving block 207, thereby driving the connecting sleeve 202 to move, and the driving sleeve 201 and the driving block 207 are arranged on the outside of the flexible transparent umbrella cover 406, so that the expansion and contraction of the flexible transparent umbrella cover 406 do not affect the manual pushing of the driving block 207.

[0062] like Figures 1 to 8 As shown, the clamping part includes: a fixing column 303, which is arranged on the connecting sleeve 202; a U-shaped clamping rod 304, one end of which is connected to the fixing column 303; a clamping block 301, which is arranged on the fixing sleeve 204 and corresponds to the fixing column 303; a heart-shaped clamping groove 302, which is opened on the clamping block 301, and the other end of the U-shaped clamping rod 304 is engaged with the heart-shaped clamping groove 302.

[0063] When the yoke 202 is in the closed position, the yoke 202 is in the closed position, and the yoke 202 is in the closed position, so that the yoke 202 can be easily opened and closed.

[0064] like Figures 1 to 8 As shown, the spray head 102 is connected to the other end of the gun rod (101); and the hanging ring 104 is provided on the spray gun 1 to facilitate the placement of the spray gun (1).

[0065] In an embodiment of the present invention, when the dust-proof device is placed as a whole on the spray gun 1, the connecting sleeve 202 is first sleeved on the gun barrel 101, and then the fixed sleeve 204 is driven to be sleeved on the gun barrel 101, and the fixed sleeve 204 is placed at the tail of the gun barrel 101; wherein, the inner wall of the fixed sleeve 204 is configured to be elastic rubber-like, thereby preventing the fixed sleeve 204 from slipping off the gun barrel 101.

[0066] Working principle: When placing the dustproof device as a whole on the spray gun 1, first put the connecting sleeve 202 on the gun rod 101, and then drive the fixed sleeve 204 to be put on the gun rod 101 together, and the fixed sleeve 204 is placed at the tail end of the gun rod 101; when working, the driving sleeve 201 is driven to move by manually pushing the driving block 207, thereby driving the connecting sleeve 202 to move in the direction close to the fixed sleeve 204, and continuing to push, so that the U-shaped clamping rod 304 moves into the heart-shaped clamping groove 302, and the U-shaped clamping rod 304 moves along one end of the heart-shaped clamping groove 302 to the top end of the heart-shaped clamping groove 302. At this time, due to the heart-shaped clamping groove 30 2, the top of the U-shaped clamping rod 304 is clamped, so that the connecting sleeve 202 and the device fixing column 303 cannot be moved in the reverse direction. At this time, the connecting ear 401 on the connecting sleeve 202 slides in the direction close to the fixing sleeve 204, and the limiting rod 403 moves along the sliding groove 404 on the umbrella rib rod 402 in the direction away from the connecting ear 401. The connecting ear 401 and the limiting rod 403 limit the umbrella rib rod 402, so that the umbrella rib rod 402 is rotated around the end close to the connecting ear 401, and the umbrella rib rod 402 is rotated to a certain angle and fixed, thereby expanding the flexible transparent umbrella cover 406, completing the protection against flying debris.

[0067] After the work is completed, when the spray gun 1 needs to be hung on the wall, the driving block 207 is manually pushed again, and the U-shaped clamping rod 304 is pushed forward through the driving sleeve 201, the connecting sleeve 202 and the fixing column 303, and the driving block 207 is manually loosened, so that the U-shaped clamping rod 304 moves out along the other end of the heart-shaped clamping groove 302, so that the U-shaped clamping rod 304 is freed from the restriction of the heart-shaped clamping groove 302, and the connecting sleeve 202 slides in the direction away from the fixing sleeve 204 under the action of the rebound force of the connecting spring 206, driving the umbrella rib rod 402 to rotate in the opposite direction, thereby shrinking the flexible transparent umbrella cover 406, making it convenient to hang it on the wall together with the spray gun 1, without having to disassemble and install it every time it is used.

[0068] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
