Description

Technical Field

[0001] The present invention relates to the technical field of painting tools, and particularly to a painting positioning and marking tool. Background Art

[0002] A painting positioning and marking tool is a marking tool suitable for daily craftsmanship, woodworking drilling, precise wall drilling, etc. that require accurate positioning. Such tools can accurately mark the target point by measuring and pressing at the target point, helping the operator quickly and accurately find the operation point for construction. Compared with using a pencil for positioning, this tool is more convenient to use and has a wider range of applications.

[0003] In the prior art, since most painting positioning and marking tools are fixed to the paint can by a non-detachable snap-fastening method and cannot be separated once combined with the paint can, this means that one painting tool can only use one painting color, which limits the flexibility of the tool. Especially when marking on the surfaces of objects of different colors, being unable to replace the paint bottle means that if the painting color needs to be changed, the entire tool must be replaced, which not only increases the cost but also reduces the applicability of the tool.

[0004] Based on the above defects, a painting positioning and marking tool is provided. Summary of the Invention

[0005] The purpose of the present invention is to provide a painting positioning and marking tool to solve the above problems.

[0006] To achieve the above purpose, the present invention adopts the following technical solution: A painting positioning and marking tool includes a rotating sleeve, a fastening sleeve is arranged on the rotating sleeve, a docking structure one for assembling with the fastening sleeve is formed on the rotating sleeve, a plurality of clamping pieces two distributed in a ring are formed at the bottom of the fastening sleeve, the clamping pieces two penetrate the rotating sleeve, a pressing structure is arranged in the rotating sleeve, and when the rotating sleeve rotates relative to the fastening sleeve, the plurality of clamping pieces two can synchronously contract under the action of the pressing structure, and a painting part is assembled inside the fastening sleeve.

[0007] Preferably, the docking structure one includes an insertion tube integrally formed at the top of the rotating sleeve, and a clamping piece one is formed on the insertion tube.

[0008] Preferably, the rotating sleeve, the insertion tube and the clamping piece one are in a trapezoidal structure, and a trapezoidal groove adapted thereto is formed inside the fastening sleeve.

[0009] Preferably, the pressing structure includes an arc-shaped groove formed on the rotating sleeve for the clamping piece two to penetrate and slide, and a supporting rib for acting on the clamping piece two is formed on the inner wall of the rotating sleeve.

[0010] Preferably, the paint spray part includes a connecting pipe, the bottom of the connecting pipe is formed with a docking pipe that matches the output end of the paint can, the top of the connecting pipe is connected to and fixed with a conduit, the top of the conduit is connected to and fixed with a conical nozzle, and the bottom of the connecting pipe is formed with a docking structure 2 that matches the plug-in assembly.

[0011] Preferably, the second docking structure comprises a clamping piece three formed at the bottom of the connecting tube, and a trapezoidal groove is formed inside the insert tube to limit the clamping piece three from sliding upward.

[0012] Preferably, the side wall of the conduit is formed with protruding wings distributed in a ring shape, and a gap for the protruding wings to slide into is formed between two adjacent clamping pieces.

[0013] Preferably, the nozzle at the top of the conical nozzle has a Y-shaped spray shape. The nozzle at the top of the conical nozzle has a Y-shaped spray shape.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In the present application, the docking structure 1 between the rotating sleeve and the fastening sleeve, as well as the design of the clamping piece 2, allow the user to quickly assemble and disassemble the paint spray part and the paint bottle through a simple rotating operation. The clamping piece 2 can be synchronously retracted under the action of the compression structure, so that the fastening force can be flexibly adjusted to ensure the stability of the paint spray part during the painting process, and at the same time facilitate the switching of paint bottles of different colors. This design not only improves the efficiency and application scope of painting, but also reduces the difficulty and cost of operation, and has high practicality and promotion value.

[0015] 2. In this application, the convex wing is aligned with the gap by rotating the conduit. As the conical nozzle is pressurized, the conduit has a space to shrink toward the inside of the fastening sleeve, and the output end of the paint can is squeezed by the butt joint to achieve the painting effect. The convex wing is staggered with the gap by rotating the conduit. At this time, the contraction of the conduit is limited, thereby limiting the random painting of the tool, which has high practicality and reliability. 3. In this application, the Y-shaped nozzle design of the conical nozzle makes the spray shape more concise and direct, improves the painting effect, and this design helps to make the marking points more uniform, intuitive and accurate.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0019] Please refer to Figures 1 - 5 , the present invention provides a technical solution: a spray painting positioning marking tool, including a rotating sleeve 1, a fastening sleeve 5 is arranged on the rotating sleeve 1, a docking structure one for assembling with the fastening sleeve 5 is formed on the rotating sleeve 1, a plurality of second clamping pieces 6 distributed in a ring are formed at the bottom of the fastening sleeve 5, the second clamping pieces 6 penetrate through the rotating sleeve 1, and a pressing structure is arranged in the rotating sleeve 1. When the rotating sleeve 1 rotates relative to the fastening sleeve 5, the plurality of second clamping pieces 6 can be synchronously retracted under the action of the pressing structure, and a spray painting part is assembled inside the fastening sleeve 5.

[0020] The fastening sleeve 5 is installed on the rotating sleeve 1 for assembling and docking the spray painting part and the paint can. The second clamping pieces 6 can pass through the rotating sleeve 1 to fix the spray painting part. When the rotating sleeve 1 rotates relative to the fastening sleeve 5, the second clamping pieces 6 can be synchronously retracted under the action of the pressing structure to adjust the fastening force for clamping the paint can. The spray painting part is installed inside the fastening sleeve 5 and is the part that actually needs to be spray painted. Through the combination of the fastening sleeve 5 and the second clamping pieces 6, the spray painting part and the paint can are assembled for precise spray painting. The docking structure one is the assembly structure between the rotating sleeve 1 and the fastening sleeve 5 to ensure that the two can work together. When in use, the user controls the rotation of the rotating sleeve 1 relative to the fastening sleeve 5 to realize the disassembly and assembly of the spray painting part and the paint bottle, which is beneficial for the user to easily switch paint bottles of different colors according to needs, not only improving the efficiency and accuracy of spray painting, but also reducing the operation difficulty and cost, and having high practicability and promotion value.

[0021] Specifically, as Figures 1 - 3As shown, the docking structure 1 includes an insert tube 3 integrally formed on the top of the rotating sleeve 1, and a clamping piece 4 is formed on the insert tube 3. The rotating sleeve 1, the insert tube 3 and the clamping piece 4 are in a ladder-like structure, and a matching trapezoidal groove is formed inside the fastening sleeve 5.

[0022] By embedding the insert tube 3 and the clamping piece 4 into the trapezoidal groove, when the clamping piece 4 passes through the trapezoidal groove, a reliable connection can be provided, which is not easy to loosen or fall off. This design can ensure the stability of the spray paint part during the painting process and prevent uneven or deviation painting caused by loosening of the spray paint part. The clamping piece 4 is an arc-shaped flat elastic component, and its head is a hook-shaped structure. When it passes through the fastening sleeve 5, it can shrink inward synchronously under the pressure of the inner wall of the fastening sleeve 5. After passing through the fastening sleeve 5, it will be elastically reset and opened, and abut against the port of the fastening sleeve 5 so that the rotating sleeve 1 can be tightly buckled with the fastening sleeve 5.

[0023] Specifically, Figure 1 As shown, the compression structure includes an arc groove 101 formed on the rotating sleeve 1 and cooperated with the clamping piece 2 6 to slide through, and the inner wall of the rotating sleeve 1 is formed with a supporting convex strip 2 for the clamping piece 2 6 .

[0024] The arc groove 101 provides a sliding path for the clamping piece 2 6 to move in the rotating sleeve 1. The main function of the supporting convex strip 2 is to provide pressure to the clamping piece 2 6 so that it can retract when needed. When the rotating sleeve 1 rotates and drives the supporting convex strip 2 to move, the supporting convex strip 2 presses the outer wall of the clamping piece 2 6, causing the clamping piece 2 6 to retract, thereby clamping the paint bottle.

[0025] Specifically, Figure 1 As shown, the paint spraying part includes a connecting pipe 7, the bottom of which is formed with a docking pipe 702 that fits in with the output end of the paint can, the top of the connecting pipe 7 is connected and fixed with a conduit 8, the top of the conduit 8 is connected and fixed with a conical nozzle 9, and the bottom of the connecting pipe 7 is formed with a docking structure 2 that fits in with the insert pipe 3.

[0026] The connecting pipe 7 is responsible for connecting the paint can and the nozzle. The connecting pipe 7 is hollow and is used to transport the paint. The function of the docking pipe 702 is to ensure that the paint can flow smoothly from the paint can into the connecting pipe 7. The conduit 8 is hollow and is used to transport the paint from the connecting pipe 7 to the conical nozzle 9. The function of the docking structure 2 is to ensure that the paint spraying parts can be assembled and connected with the rotating sleeve 1.

[0027] The second docking structure includes a clamping piece 3 701 formed at the bottom of the connecting tube 7 , and a trapezoidal groove is formed inside the inserting tube 3 to limit the clamping piece 3 701 from sliding upward.

[0028] The clamping piece 3 701 is located at the bottom of the connecting tube 7, and is designed to cooperate with the trapezoidal groove inside the insert tube 3, thereby limiting the upward slipping of the clamping piece 3 701, and ensuring a stable and reliable connection between the spray paint part and the rotating sleeve 1. The assembly of the clamping piece 3 701 and the insert tube 3 is the same as the assembly of the clamping piece 1 4 and the fastening sleeve 5, and a stable connection between the spray paint part and the rotating sleeve 1 is achieved.

[0029] The side wall of the conduit 8 is formed with protruding wings distributed in an annular shape, and a gap is formed between two adjacent clamping pieces 4 to fit the protruding wings. The nozzle spray shape at the top of the conical nozzle 9 is designed in a Y-shaped shape. The concave design of the outer wall of the fastening sleeve 5 makes it convenient for users to hold the marking tool. This design increases the ergonomic characteristics of the tool and improves the comfort and controllability during use.

[0030] Through the gap setting between the two clamping pieces 4, when in use, the conduit 8 is rotated to align the convex wing with the gap. As the conical nozzle 9 is pressed, the conduit 8 fixed to the conical nozzle 9 has space to shrink toward the inside of the fastening sleeve 5, and the output end of the paint can is squeezed through the docking tube 702 to achieve the painting effect. By rotating the conduit 8, the convex wing is staggered with the gap. At this time, the shrinkage of the conduit 8 is limited, thereby limiting the random painting of the tool, which has high practicality and reliability.

[0031] The spray shape of the nozzle at the top of the conical nozzle 9 is designed in a Y-shaped design. After the nozzle sprays the paint, it presents a Y-shaped effect, which is more concise and direct, and has a conical structure, which is conducive to marking areas with relatively narrow spaces.

[0032] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
