Description

Technical Field

[0001] This utility model relates to the field of aerosol can technology, specifically a compressible self-spraying paint aerosol can. Background Technology

[0002] Paint spray cans are widely used in various scenarios due to their convenience and ease of use, such as model making, handicrafts, creative renovation, paint repair, graffiti, decoration, renovation, and rust prevention. Paint spray cans contain a propellant, usually compressed gas. When the pump head is pressed, the compressed gas pushes the paint out to achieve the painting effect.

[0003] Existing spray paint aerosol cans typically require users to press the pump head to spray paint. Continuous pressing will spray paint continuously, and stopping the pressing will stop the spraying. The pump head is usually made of hard plastic and the surface is usually textured with anti-slip features. Pressing the pump head for a long time can easily cause pain in the user's fingers, resulting in poor user comfort. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a compressible spray paint aerosol can to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a compressible spray paint aerosol can, comprising an aerosol can body, a pump head mounted on the top of the aerosol can body, a limit plate fixed on one side of the pump head, a bracket connected below one side of the pump head, a support sleeve connected on one side of the bracket, a limit pin passing through one side of the support sleeve, a spring sleeved on the outside of the limit pin, and a lever sleeved on the outside of the limit pin.

[0006] By adopting the above technical solution, if long-term pressing is required, the user directly presses down on the nozzle of the pump head. The nozzle moves down, causing the limiting plate to move down as well. The bottom of the limiting plate is sloped, which pushes the limiting pin into the bracket to compress the spring. When the limiting plate moves below the limiting pin, the spring drives the limiting pin to extend and limit the limiting plate, preventing it from moving upward and thus preventing the nozzle from moving upward. Therefore, long-term continuous painting operations can be performed without the user constantly pressing the nozzle. After the nozzle moves down, the pump head opens, and the paint in the aerosol can body is sprayed out from the nozzle. When it is necessary to stop painting, the user only needs to pull the lever to move the limiting pin away from above the limiting plate, and then the pump head... The spray nozzle moves upward to reset and stop painting. If short-term painting is required, the user can rotate the lever. Due to the sloping side of the support sleeve, the lever will move horizontally against the side wall of the support sleeve during rotation. At the same time, the lever drives the limit pin to move horizontally, causing the limit pin to retract into the bracket. When the pump head nozzle is pressed laterally, the limit plate will not contact the limit pin, which is convenient for short-term painting. At this time, the spring is in a compressed state and continuously applies pressure to the limit pin and the lever, so that there is a certain friction between the lever and the support sleeve, preventing the limit pin from popping out due to random rotation of the lever. When it is necessary to return to the state of long-term pressing, the user should rotate the lever forcefully so that the spring can drive the limit pin to pop out.

[0007] Furthermore, the bottom of the limiting plate is sloped, and the limiting plate abuts against the limiting pin.

[0008] By adopting the above technical solution, the pump head nozzle moves downward, causing the limiting plate to move downward. The bottom of the limiting plate is sloped, which can push the limiting pin into the bracket to compress the spring. When the limiting plate moves below the limiting pin, the spring drives the limiting pin to extend and limit the limiting plate. The limiting plate cannot move upward, thus preventing the pump head nozzle from moving upward.

[0009] Furthermore, the longitudinal section of the limiting pin is cross-shaped, and the limiting pin is slidably connected to the bracket and the support sleeve respectively.

[0010] By adopting the above technical solution, the shape of the limiting pin facilitates the spring to apply pressure to the limiting pin, increasing the stability of the structure. The limiting pin is retracted into the bracket and support sleeve to avoid affecting the downward movement of the pump head nozzle.

[0011] Furthermore, the limiting pin is made of POM material.

[0012] By adopting the above technical solution, POM has high strength and low surface friction coefficient, which can reduce the wear of the limit pin, extend the service life of the structure, and prevent the spring from being worn. At the same time, the low friction coefficient reduces resistance, making it easier for the limit plate to move vertically downward and push the limit pin to move laterally. Compared with the use of materials with high friction coefficient, it is more labor-saving.

[0013] Furthermore, one side of the support sleeve is sloped, and the lever is slidably connected to one side of the support sleeve.

[0014] By adopting the above technical solution, when the user rotates the lever, the side of the support sleeve is sloping, causing the lever to move horizontally against the side wall of the support sleeve during rotation. At the same time, the lever drives the limit pin to move horizontally, thereby causing the limit pin to retract into the bracket.

[0015] Furthermore, the bottom of the bracket is circular, and the bracket is detachably connected to the pump head by bolts.

[0016] By adopting the above technical solution, manufacturers can easily recycle brackets, support sleeves, limit pins, springs and levers for use in new aerosol cans, and it also facilitates assembly operations during production.

[0017] Furthermore, the longitudinal section of one side of the limiting pin is rhomboid, and the lever plate is detachably connected to the limiting pin by bolts, and the support sleeve is detachably connected to the bracket by bolts.

[0018] By adopting the above technical solution, during assembly, the spring is placed on the limiting pin, then the limiting pin is inserted into the support sleeve, and then the lever is placed on one end of the limiting pin and fastened with bolts. At this time, the limiting pin and the spring cannot be separated from the support sleeve. One end of the limiting pin is diamond-shaped, which makes it easy for the lever to rotate and drive the limiting pin to rotate, without the phenomenon of relative movement between the limiting pin and the bolt.

[0019] Furthermore, the cross-section of the top of the bracket is "C" shaped, and the limiting plate is slidably connected to the bracket.

[0020] By adopting the above technical solution, the shape of the bracket can guide the limiting plate, so that the limiting plate can only move up and down, thereby preventing the pump head nozzle from rotating and causing the limiting plate to revolve away from the area where the limiting pin is located, thus affecting the locking of the limiting pin.

[0021] In summary, the present invention has the following main advantages:

[0022] This invention, through the design of a limiting plate, support sleeve, limiting pin, spring, and lever, allows for continuous painting operations without the need for constant pressure. By pressing down on the nozzle of the pump head, the nozzle moves downwards, causing the limiting plate to move downwards as well. The sloped bottom of the limiting plate pushes the limiting pin into the bracket, compressing the spring. When the limiting plate moves below the limiting pin, the spring drives the limiting pin to extend and limit the limiting plate, preventing it from moving upwards and thus preventing the pump head nozzle from moving upwards. Therefore, continuous painting operations can be performed without the user constantly pressing down on the nozzle. To stop painting, the user simply pulls the lever. The limiting pin moves away from the top of the limiting plate, after which the pump head drives the nozzle to move upward and reset, stopping the painting. If short-term painting is required, the lever can be rotated. Because the side of the support sleeve is sloping, the lever will abut against the side wall of the support sleeve and move horizontally during rotation. At the same time, the lever drives the limiting pin to move horizontally, thereby retracting the limiting pin into the bracket. When the pump head nozzle is pressed laterally, the limiting plate will not contact the limiting pin, which is convenient for short-term painting. The structure is simple and easy to operate, avoiding the phenomenon of finger injury and pain caused by pressing the pump head nozzle for a long time. Both short-term and long-term painting are easy to operate. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The embodiments of this utility model will be described below based on its overall structure.

[0031] Example 1:

[0032] A compressible spray paint aerosol can, such as Figures 1-5 As shown, the device includes an aerosol can body 1, a pump head 2 mounted on the top of the aerosol can body 1, a limit plate 3 fixed to one side of the pump head 2, the bottom of the limit plate 3 being sloping, a bracket 4 connected to the lower side of one side of the pump head 2, a support sleeve 5 connected to one side of the bracket 4, and a limit pin 6 passing through one side of the support sleeve 5. The limit pin 6 is made of POM material, and the limit plate 3 abuts against the limit pin 6. The longitudinal section of the limit pin 6 is cross-shaped. The limit pin 6 is slidably connected to the bracket 4 and the support sleeve 5 respectively. A spring 7 is sleeved on the outside of the limit pin 6 to limit the movement. A lever plate 8 is sleeved on the outside of pin 6. One side of the support sleeve 5 is sloped. The lever plate 8 is slidably connected to one side of the support sleeve 5. If long-term pressing is required, the user directly presses down on the nozzle of the pump head 2. The nozzle of the pump head 2 moves down, causing the limiting plate 3 to move down. The bottom of the limiting plate 3 is sloped, which can push the limiting pin 6 into the bracket 4 to compress the spring 7. When the limiting plate 3 moves below the limiting pin 6, the spring 7 drives the limiting pin 6 to extend and limit the limiting plate 3. The limiting plate 3 cannot move up, thus preventing the nozzle of the pump head 2 from moving up. Therefore, it is not necessary to use... The operator can perform continuous painting operations by pressing the nozzle continuously; when the nozzle of pump head 2 moves down, pump head 2 opens, and the paint in the aerosol can body 1 is sprayed out from the nozzle of pump head 2; when it is necessary to stop painting, the operator only needs to pull the lever 8 to move the limit pin 6 away from the limit plate 3, and then the pump head 2 drives the nozzle to move up to reset and stop painting; if short-term painting is required, the operator can rotate the lever 8. Since the side of the support sleeve 5 is sloping, the lever 8 will abut against the side wall of the support sleeve 5 during rotation to create a horizontal position. During the movement, the lever 8 drives the limit pin 6 to move horizontally, thereby retracting the limit pin 6 into the bracket 4. When the nozzle of the pump head 2 is pressed laterally, the limit plate 3 will not contact the limit pin 6, which facilitates short-term painting. At this time, the spring 7 is in a compressed state and continuously applies pressure to the limit pin 6 and the lever 8, so that there is a certain friction between the lever 8 and the support sleeve 5, preventing the lever 8 from rotating arbitrarily and causing the limit pin 6 to pop out. When it is necessary to restore the state of long-term pressing, the user rotates the lever 8 forcefully, so that the spring 7 can drive the limit pin 6 to pop out.

[0033] See Figures 1-5 In the above embodiment, the bottom of the bracket 4 is circular, the bracket 4 is detachably connected to the pump head 2 by bolts, the longitudinal section of one side of the limiting pin 6 is rhomboid, the lever plate 8 is detachably connected to the limiting pin 6 by bolts, and the support sleeve 5 is detachably connected to the bracket 4 by bolts. This makes it convenient for the manufacturer to recycle the bracket 4, support sleeve 5, limiting pin 6, spring 7 and lever plate 8 for new aerosol cans, and also facilitates the assembly operation during production.

[0034] Example 2:

[0035] Based on the above embodiment one, the following settings are now adopted to increase the stability of the structure.

[0036] See Figures 1-4 In the above embodiment, the cross-section of the top of the bracket 4 is "C" shaped. The limiting plate 3 is slidably connected to the bracket 4. The shape of the bracket 4 can guide the limiting plate 4, so that the limiting plate 4 can only move up and down, thereby avoiding the pump head 2 nozzle rotation causing the limiting plate 4 to revolve away from the area where the limiting pin 6 is located, affecting the locking of the limiting pin 6.

[0037] The implementation principle of this utility model is as follows: First, if long-term pressing is required, the user directly presses down the nozzle of the pump head 2. The nozzle of the pump head 2 moves down, causing the limiting plate 3 to move down. The bottom of the limiting plate 3 is sloped, which can push the limiting pin 6 into the bracket 4 to compress the spring 7. When the limiting plate 3 moves below the limiting pin 6, the spring 7 drives the limiting pin 6 to extend and limit the limiting plate 3. The limiting plate 3 cannot move up, thus preventing the nozzle of the pump head 2 from moving up. Therefore, long-term continuous painting can be carried out without the user constantly pressing the nozzle. After the nozzle of the pump head 2 moves down, the pump head 2 opens. At this time, the paint in the aerosol can body 1 is sprayed out from the nozzle of the pump head 2. When it is necessary to stop painting, the user only needs to pull the lever 8 to move the limiting pin 6 away from the top of the limiting plate 3. Then the pump head 2 drives the nozzle to move up and reset to stop painting.

[0038] If short-term painting is required, the user can rotate the lever 8. Since the side of the support sleeve 5 is sloping, the lever 8 will move horizontally against the side wall of the support sleeve 5 during rotation. At the same time, the lever 8 drives the limit pin 6 to move horizontally, so that the limit pin 6 retracts into the bracket 4. When the pump head 2 nozzle is pressed laterally, the limit plate 3 will not contact the limit pin 6, which is convenient for short-term painting. At this time, the spring 7 is in a compressed state and continuously applies pressure to the limit pin 6 and the lever 8, so that there is a certain friction between the lever 8 and the support sleeve 5, preventing the lever 8 from rotating arbitrarily and causing the limit pin 6 to pop out. When it is necessary to restore the state of long-term pressing, the user should rotate the lever 8 forcefully so that the spring 7 can drive the limit pin 6 to pop out.
