Description

Technical Field

[0001] This invention relates to the field of spray guns, and in particular to a pipe connection mechanism for a spray gun used in factory renovation. Background Technology

[0002] Painting factory walls is a crucial step in factory renovation. A spray gun is an automated painting device that allows for rapid and uniform spraying of factory walls by hand, ensuring both efficiency and quality. Existing spray guns typically have two pipes connected: an air inlet pipe and a feed pipe. These pipes are often made of soft materials, making insertion difficult due to high friction. This can lead to wrinkles or damage due to the force and friction during insertion, affecting the normal operation of the spray gun and causing production losses for the user. Therefore, a pipe connection mechanism for spray guns used in factory renovation is proposed. Summary of the Invention

[0034] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the present invention will be described in detail with reference to the schematic diagrams.

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0037] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0038] Example 1

[0039] Reference Figure 1 and 2 This embodiment provides a pipe connection mechanism for a spray gun used in factory renovation.

[0040] The pipe connection mechanism for the spray gun used in factory renovation includes a connector assembly 100.

[0041] Specifically, the connector assembly 100 includes an interface seat 101 fixed to the rear end of the spray gun, and two inlets 102 are symmetrically opened on one side of the interface seat 101. An air inlet pipe 104 and a feed pipe 105 are respectively inserted into the two inlets 102, and an outlet 103 is provided at the ports of both inlets 102.

[0042] When in use, the air inlet pipe 104 and the feed pipe 105 are respectively connected to the two inlets 102 to enable the spray gun to operate.

[0043] Example 2

[0044] Reference Figure 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment and differs from the previous embodiment in that:

[0045] The pipe connection mechanism of the spray gun used for factory renovation also includes a positioning component 200.

[0046] Specifically, each inlet 102 is equipped with a positioning component 200, which can be used to fix the air inlet pipe 104 or the feed pipe 105 respectively. The positioning component 200 includes an external pressure member 201 located at the port of the inlet 102. An ejector 202 is provided inside the external pressure member 201, and a power member 203 is provided outside the ejector 202. At the same time, a power cavity 101a is also provided inside the interface seat 101, and the power member 203 is installed in the power cavity 101a. An internal extrusion member 204 is provided at the other end of the inlet 102.

[0047] Furthermore, the external pressure component 201 includes a fixed ring 201a slidably disposed inside the inlet 102. The outer edge of the end face of the fixed ring 201a has multiple guide ribs 201b arranged in a ring array. Multiple guide grooves 102a are also provided on the inner wall of the inlet 102. Thus, the radial rotation of the fixed ring 201a can be locked through the sliding engagement of the guide ribs 201b and the guide grooves 102a, so that the fixed ring 201a can only move horizontally along the guide grooves 102a in the axial direction of the inlet 102. Multiple retractable external pressure plates 201c are arranged in a ring array through the inner side of the fixed ring 201a. An inner push spring 201d is sleeved between the multiple external pressure plates 201c and the inner wall of the fixed ring 201a. The inner push spring 201d can provide elastic support for the external pressure plates 201c, so that the external pressure plates 201c are always in a retracted state when not in use, which does not affect the insertion of the air inlet pipe 104 and the feed pipe 105.

[0048] The ejector 202 includes a rotating ring 202a sleeved around the center of the fixed ring 201a, with both ends of the rotating ring 202a embedded in the fixed ring 201a to ensure a stable connection between the rotating ring 202a and the fixed ring 201a. A first push groove 202b is provided on the outer side of the rotating ring 202a. At the same time, a plurality of protrusions 202c that can cooperate with the outer pressure plate 201c are integrally provided on the inner wall of the rotating ring 202a along its axial direction. The contact surfaces between the protrusions 202c and the outer pressure plate 201c are all arc-shaped. Thus, when the rotating ring 202a rotates, the outer pressure plate 201c can be extended under the push of the protrusions 202c through the gradual contact between the protrusions 202c and the outer pressure plate 201c, so as to facilitate its subsequent cooperation with the outer pipe.

[0049] The power component 203 includes an active push plate 203a movably embedded in the upper part of the power cavity 101a. A transmission gear 203b is meshed on one side of the lower part of the active push plate 203a, and a driven push plate 203c is meshed on the lower part of the transmission gear 203b. The active push plate 203a and the driven push plate 203c are centrally symmetrical about the transmission gear 203b. One bottom end of the driven push plate 203c is connected to the fixed ring 201a, so that the fixed ring 201a can move synchronously with the driven push plate 203c. A second push post 203d is also fixedly provided at the bottom of the driven push plate 203c. A top plate 203e is also fixed on one side of the active push plate 203a. A top spring 203f is provided on the outer side of the top plate 203e. The top spring 203f can provide a reset thrust for the active push plate 203a through its own elasticity.

[0050] The inner extrusion component 204 includes a fixed seat 204a disposed inside the inner port of the inlet 102. The end face of the fixed seat 204a has an opening 204b, and a rotating disk 204c is rotatably mounted on the outer side of the fixed seat 204a. The outer wall of the rotating disk 204c has a second push groove 204d, and one end of the second push groove 204d is correspondingly connected to the opening 204b. A push block 204e is disposed on one side surface of the rotating disk 204c, and multiple push blocks 204e are arranged in a ring array on its surface about the rotating disk 204c. Multiple inner extrusion plates 204f are arranged in a ring array through the interior of the fixed seat 204a, and the surfaces of the multiple inner extrusion plates 204f are all provided with inner receiving grooves 204g that cooperate with the push blocks 204e.

[0051] Furthermore, both the active push plate 203a and the driven push plate 203c have toothed blocks on their surfaces. Both the active push plate 203a and the driven push plate 203c mesh with the transmission teeth 203b, which are located between the active push plate 203a and the driven push plate 203c. Thus, when the active push plate 203a moves, it pushes the transmission teeth 203b, and the transmission teeth 203b themselves drive the driven push plate 203c. This allows the driven push plate 203c to move in the opposite direction to the active push plate 203a, thereby driving the fixed ring 201a to move and achieving contact between the outer pressure plate 201c and the air inlet pipe 104 and the feed pipe 105.

[0052] Preferably, the first push groove 202b is spirally inclined along the outer side of the rotating ring 202a, and a first push post 102b is also provided on the inner wall of the inlet 102. The first push post 102b and the first push groove 202b are slidably fitted together. Thus, when the rotating ring 202a moves horizontally with the fixed ring 201a, under the cooperation of the fixed first push post 102b and the first push groove 202b, the force exerted by the first push post 102b on the groove wall of the first push groove 202b causes the rotating ring 202a to rotate relative to the fixed ring 201a. This changes the previous staggered arrangement between the outer pressure plate 201c and the protrusion 202c to a state where their tops abut against each other, realizing the outward extension of the outer pressure plate 201c. After the plate 201c extends and fits against the air inlet pipe 104 or the feed pipe 105, it fixes the pipe. At the same time, under the friction between the outer pressure plate 201c and the pipe, the pipe can be driven by the friction of the outer pressure plate 201c to move synchronously with the fixing ring 201a to the depth of the inlet 102, which makes the insertion of the pipe more convenient and avoids damage or wrinkles to the pipe due to the large resistance during the insertion, thus affecting the smooth use of the pipe. At the same time, the outer edge of the end face of the fixing ring 201a is also provided with a mating port 201e, which is connected to the first push groove 202b, thereby meeting the need for the first push column 102b to enter or leave the first push groove 202b as the fixing ring 201a and the rotating ring 202a move.

[0053] Furthermore, the opening 204b is connected to the second push groove 204d, so that as the driven push plate 203c moves, the second push post 203d located at its bottom can enter the second push groove 204d through the opening 204b. The second push groove 204d is spirally inclined about the rotating disk 204c. The second push groove 204d and the second push post 203d are in sliding fit. As the second push post 203d gradually enters, the rotating disk 204c can be driven to rotate through the second push groove 204d to achieve subsequent control of the fit with the inner extrusion plate 204f.

[0054] Multiple inner extrusion plates 204f are arranged in a ring array around the fixing seat 204a. Each inner extrusion plate 204f has an inner converging groove 204g on its surface. The inner converging groove 204g is arc-shaped and is fitted with a push block 204e located on the surface of the rotating disk 204c. When the push block 204e rotates with the rotating disk 204c, the inner extrusion plates 204f can be pushed radially outward along the fixing seat 204a by the arc-shaped sliding of the push block 204e inside the inner converging groove 204g. This can compress the inner wall of the pipe that has moved into place. Thus, the pipe is fixed by the cooperation of the inner extrusion plates 204f and the outer pressure plate 201c with the inner and outer walls of the pipe.

[0055] During pipe connection, the active push plate 203a is located inside the inlet 102. The pipe is inserted into the corresponding inlet 102, with the pipe tip abutting against the inner edge of the retaining ring 201a. Then, the active push plate 203a is pushed outwards. Driven by the transmission gear 203b, as the active push plate 203a moves outwards, the driven push plate 203c drives the retaining seat 204a to move horizontally along the guide groove 102a. With the push of the driven push plate 203c, the first push post 102b moves in the first push groove 201a. The internal movement of 2b causes the rotating ring 202a to rotate. The inner protrusion 202c of the rotating ring 202a pushes the outer pressure plate 201c out to contact the outer wall of the pipe. As the fixed ring 201a moves further with the driven push plate 203c, the friction between the outer pressure plate 201c and the pipe drives the pipe to move synchronously deeper into the inlet 102. When the second push post 203d at the bottom of the driven push plate 203c enters the second push groove 204d from the opening 204b, the rotation... The disc 204c rotates as the driven push plate 203c moves, causing the inner extrusion plate 204f to retract inward and fit against the inner wall of the pipe under the cooperation of the inner groove 204g and the push block 204e. At this point, the pipe is fixed in place by the combined action of the inner extrusion plate 204f and the outer pressure plate 201c. When the pipe is pulled out, the active pusher is pushed towards the outlet 103, and the pipe is released and pulled out by the outward movement of the driven push plate 203c. The outer pressure component 201c... 1. The joint cooperation of the ejector 202, the power unit 203, and the inner extruder 204 allows the pipe to be inserted into the inlet 102 by the external pressure unit 201, which will drive it to penetrate deeper into the inlet 102 and cooperate with the inner extruder 204 to fix the pipe. The pipe connection can be completed without forcefully inserting the pipe, avoiding wrinkles or damage to the soft air inlet pipe 104 and feed pipe 105 due to excessive resistance, thus ensuring the normal use of the air inlet pipe 104 and feed pipe 105.

[0056] Example 3

[0057] Reference Figure 1-6 This is the third embodiment of the present invention, which is based on the previous embodiment and differs from the previous embodiment in that:

[0058] The pipe connection mechanism of the spray gun used for factory renovation also includes a locking component 300.

[0059] Specifically, the locking assembly 300 includes a locking disc 301 located outside the power component 203. The locking disc 301 is fixedly connected to the outside of both power components 203, and a clamping member 302 is provided on the outside of the locking disc 301. At the same time, a control member 303 is installed between the two sets of clamping members 302. The control member 303 is movably embedded inside the interface seat 101.

[0060] Furthermore, the clamping member 302 includes a clamping rod 302a, with a retaining ring on the outside of the clamping rod 302a, and a return spring 302b sleeved on the outside of the clamping rod 302a. The return spring 302b is disposed between the retaining ring and the inner cavity wall of the interface seat 101 to provide elastic support for the clamping rod 302a, which can ensure that the clamping rod 302a can quickly move and return to its original position when it is not blocked by the control member 303.

[0061] The control component 303 includes a console 303a. A support spring is provided at the bottom of the console 303a to support the console 303a. Through the elastic extension and contraction of the support spring, the console 303a can move at two horizontal heights. At the same time, two notches 303c are symmetrically provided at the lower part of the console 303a, and a ramp 303d is provided on the outer side of the middle part of the console 303a.

[0062] Preferably, the locking disc 301 is fixed to the inner end face of the transmission tooth 203b, and the end face of the locking disc 301 is inclined in a spiral shape with increasing height. Thus, by the contact between the abutment rod 302a and the end face of the locking disc 301, unidirectional rotation locking of the transmission tooth 203b can be achieved. Thus, by locking the transmission tooth 203b, the overall locking of the fixed pipeline is achieved, ensuring the stability of the pipeline connection.

[0063] Furthermore, the lower part of the control panel 303a abuts against the abutment rod 302a. The abutment rod 302a and the notch 303c are fitted together. In the locked state, one end of the abutment rod 302a abuts against the bottom of the control panel 303a, so the abutment rod 302a is stationary, thus locking the transmission gear 203b. When the control panel 303a rotates, by rotating the control panel 303a clockwise and counterclockwise, the left and right notches 303c can respectively engage with the left and right abutment rods 302a. When the notch 303c rotates to the end of the abutment rod 302a, the restriction on the abutment rod 302a is removed. At this time, under the action of the return spring 302b, the other end can disengage from the transmission gear 203b, releasing the restriction on the transmission gear 203b. Thus, the outer push spring 203f can pull the active push. Plate 203a moves inward, and driven push plate 203c moves outward to release the pipe fixation. At the same time, if the control console 303a is pressed down, the inclined platform 303d in the middle section of the control console 303a moves to the stop rod 302a. At this time, the obstruction on both sides of the stop rod 302a disappears simultaneously, that is, the restriction on both sides of the transmission gear 203b is released simultaneously. The fixation of the air inlet pipe 104 and the feed pipe 105 can be released simultaneously. Through the joint cooperation of the control component 303, the stop component 302 and the locking disc 301, the movement of the power component 203 is locked under the rotation restriction of the locking disc 301, thereby achieving the fixation of the pipe after connection. At the same time, by switching the different movement states of the control component 303, the fixation of both sides of the pipe can be released simultaneously or individually, making the connection or disconnection of the pipe more convenient.
