Description

Technical Field

[0001] The present invention relates to the technical field of protective devices, and more particularly to a protective device for arts and crafts. Background Art

[0002] Arts and crafts are objects made with practical purposes through artistic design and craft technology. They include both daily necessities (such as ceramics, furniture, textiles) and decorative items (such as sculptures and ornaments); their core lies in the perfect combination of artistic beauty and practical functions.

[0003] There is a lack of protective devices when transporting handicrafts, especially ceramics. Since ceramics are fragile, even a slight bump during transportation may cause damage to the ceramics, resulting in serious economic losses.

[0004] In view of the above problems, some solutions have been provided in the prior art. For example, Chinese invention patent No. CN112707021B discloses a protective device for arts and crafts. The device can effectively prevent the arts and crafts from being damaged by friction or collision during placement and transportation by setting protective cotton and silicone protective strips at the four corners and inner walls of the second storage box and the third storage box. Although the prior art can prevent damage to the artwork to a certain extent, the protective effect of simply setting protective cotton and silicone protective strips is limited, and the protective device cannot be applied to artworks of different sizes, which seriously affects the practicability and protective effect of the protective device. Summary of the invention

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a protective device for arts and crafts, which can achieve the purpose of improving the practicality and protective effect of the protective device.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

[0008] Furthermore, the driving assembly includes a cover plate detachably mounted on the top wall of the box body, a vertical groove is opened on the top wall of the box body, a vertical plate slidingly matched with the vertical groove is fixedly mounted on the bottom wall of the cover plate, and a limiting assembly for fixing the cover plate is provided on the box body, a first magnet for pushing the mounting rod to move is provided in the sleeve, a second magnet mutually repelling the first magnet is embedded in the vertical plate, a first spring for driving the mounting rod to reset is jointly installed between the mounting plate and the sleeve, and a fixing assembly for limiting the movement of the mounting rod is provided on the mounting plate.

[0009] Furthermore, the fixing assembly includes a second spring installed between the first magnet and the mounting plate, a fixing rod is slidably installed on the mounting plate, a push rod is fixedly installed on the first magnet, an inclined groove cooperating with the push rod is provided on the fixing rod, a third spring is jointly installed between the fixing rod and the mounting plate, and a fixing groove cooperating with the fixing rod is provided on the top wall of the sleeve.

[0010] Furthermore, the negative pressure component includes a clamping plate fixedly mounted on the output end of the first elastic telescopic rod, the clamping plate is provided with a cavity, the cavity is evenly provided with air holes, and a first air pipe is inserted into the cavity.

[0011] Furthermore, a first through hole is formed on the mounting plate, a second through hole communicating with the first through hole is formed on the fixing rod, and the first through hole is communicated with the first air pipe through the second through hole.

[0012] Furthermore, a second air pipe connected to the sleeve is inserted into the first air pipe, and a blocking plate for blocking the second air pipe is fixedly mounted on the fixing rod.

[0013] Furthermore, a support plate is horizontally slidably installed on the bottom wall of the box body, and a buffer spring is commonly installed between the side wall of the support plate and the box body, an air cylinder is installed on the box body, a locking rod is slidably installed in the air cylinder, a locking groove cooperating with the locking rod is opened on the support plate, a return spring is commonly installed between the locking rod and the air cylinder, and a third air pipe connected to the sleeve is inserted on the air cylinder.

[0014] Furthermore, the limiting assembly includes a limiting rod slidably mounted on the side wall of the box body, a fourth spring is installed between the limiting rod and the box body, and a limiting groove cooperating with the limiting rod is formed on the vertical plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention provides a first elastic telescopic rod. When the vertical plate is inserted into the vertical slot, the second magnet drives the first magnet to move through repulsion, and drives the mounting plate to move during the movement of the first magnet. Then, during the movement of the mounting plate, the first elastic telescopic rod is driven by the mounting rod to contact the artwork, and the artwork is clamped together with the second elastic telescopic rod, thereby avoiding damage caused by tilting and collision during transportation of the artwork. When shaking occurs during transportation, the first elastic telescopic rod and the second elastic telescopic rod will telescope back and forth, thereby reducing the impact force on the artwork, thereby protecting the artwork. At the same time, because the first elastic telescopic rod and the second elastic telescopic rod have telescopic elasticity, they can clamp different artworks, thereby increasing the scope of application of the protection device. (2) The present invention opens a cavity, and drives the second through hole to communicate with the first through hole during the process of inserting the mounting rod into the fixing groove. At this time, the space in the sleeve located on the side of the mounting plate close to the first magnet absorbs air from the cavity through the first through hole, the second through hole, and the first air pipe, and restores the cavity. At this time, the first elastic telescopic rod drives the clamping plate to fit the artwork, and then the clamping plate and the artwork are tightly adsorbed together under the action of the pressure in the cavity. Therefore, when the artwork drives the first elastic telescopic rod to extend and retract back and forth, the clamping plate can always be adsorbed together with the artwork, effectively preventing the artwork from tilting and being damaged, and further improving the protection effect of the artwork. (3) The present invention provides a second air pipe. When the mounting plate squeezes the third spring, the airflow in the space on the side of the mounting plate away from the first magnet in the sleeve flows into the cavity through the second air pipe and the first air pipe, and blows toward the surface of the artwork through the air holes in the cavity, thereby cleaning the dust particles on the surface of the artwork, thereby preventing excessive dust particles from adhering to the surface of the artwork and affecting the fitting effect between the clamping plate and the artwork, resulting in the clamping plate and the artwork being unable to be adsorbed together. Then, when the fixing rod drives the second through hole to communicate with the first through hole, the fixing rod drives the blocking plate to block the second air pipe, thereby ensuring that the clamping plate and the artwork are adsorbed together. (4) The present invention provides a support plate. During the process of the mounting plate squeezing the first spring, the space in the sleeve located on the side of the mounting plate close to the first magnet draws air into the air cylinder through the third air pipe, and the locking rod squeezes the reset spring along the air cylinder. During the process of the locking rod squeezing the reset spring, the locking rod is separated from the limit groove, and then the support plate is driven to swing back and forth during the swinging of the artwork. At this time, the buffer spring can further reduce the impact force on the artwork. At the same time, the support plate swings with the artwork, which can reduce the wear degree of the bottom of the artwork, and further improve the protection effect of the artwork. (5) The present invention provides a locking rod. During the process in which the first spring stretches and drives the mounting plate to reset, the airflow in the space on the side of the mounting plate close to the first magnet in the sleeve is squeezed and flows into the air cylinder through the third air pipe. Then the reset spring stretches and drives the locking rod to move upward. During the process in which the locking rod moves upward, it is inserted into the limit groove again, so that the support plate can be locked, thereby preventing the support plate from shaking and causing the artwork to tilt and collide with each other and cause damage when the user takes the artwork, thereby further improving the protection effect of the artwork.

At this time, both the first flexible telescopic rod 204 and the second flexible telescopic rod 205 are compressed and have a tendency to recover. Then, the artwork can be clamped under the action of the elastic force of the first flexible telescopic rod 204 and the second flexible telescopic rod 205 themselves, thereby preventing the artwork from being damaged due to tilting or colliding during transportation. When shaking occurs during transportation, the first flexible telescopic rod 204 and the second flexible telescopic rod 205 will telescope back and forth, thereby reducing the impact force on the artwork and protecting the artwork. At the same time, since the first flexible telescopic rod 204 and the second flexible telescopic rod 205 have telescopic elasticity, different artworks can be clamped, thereby increasing the scope of application of the protection device.

[0022] When it is necessary to take out the artwork, the user can first open the cover 301, and then the cover 301 drives the vertical plate 302 to move upward and disengage from the vertical groove, and in the process of the vertical plate 302 moving upward, drives the second magnet 304 and the first magnet 303 away, at this time the first spring 305 stretches and drives the mounting plate 202 to reset, and in the process of the mounting plate 202 resetting, the first elastic telescopic rod 204 is driven to reset through the mounting rod 203, and in the process of the first elastic telescopic rod 204 resetting, it gradually disengages from the artwork, at this time the first spring 305 stretches and resets, and then the fixing effect of the artwork is released, so that it is convenient for the user to take the artwork.

[0023] The fixing assembly 4 includes a second spring 401 installed between the first magnet 303 and the mounting plate 202, a fixing rod 402 is slidably installed on the mounting plate 202, a push rod 403 is fixedly installed on the first magnet 303, an inclined groove cooperating with the push rod 403 is provided on the fixing rod 402, a third spring 404 is installed between the fixing rod 402 and the mounting plate 202, and a fixing groove 405 cooperating with the fixing rod 402 is provided on the top wall of the sleeve 201.

[0024] The negative pressure assembly 5 includes a clamping plate 501 fixedly mounted on the output end of the first elastic telescopic rod 204 , the clamping plate 501 is provided with a cavity 502 , the cavity 502 is evenly provided with air holes 503 , and the cavity 502 is inserted with a first air pipe 504 .

[0025] The mounting plate 202 is provided with a first through hole 505 , the fixing rod 402 is provided with a second through hole 506 communicating with the first through hole 505 , and the first through hole 505 is communicated with the first air pipe 504 through the second through hole 506 .

[0026] A second air pipe 507 communicating with the sleeve 201 is inserted into the first air pipe 504 , and a blocking plate 508 for blocking the second air pipe 507 is fixedly mounted on the fixing rod 402 .

[0027] By adopting the above technical solution, when the second magnet 304 approaches the first magnet 303, the first magnet 303 moves along the sleeve 201, and during the movement of the first magnet 303, the second spring 401 drives the mounting plate 202 to move, and then during the movement of the mounting plate 202, the first elastic telescopic rod 204 is driven to clamp and fix the artwork, and when the first spring 305 reaches the maximum compression degree, the mounting plate 202 cannot move further, and at this time, as the first magnet 303 moves, the second spring 401 is compressed and has There is a tendency to recover, and then in the process of the first magnet 303 compressing the second spring 401, the first magnet 303 drives the push rod 403 to gradually contact the inclined surface of the inclined groove and apply a thrust to the inclined surface of the inclined groove, and then under the action of the thrust, the fixing rod 402 is gradually inserted into the fixing groove 405, so that the position of the mounting plate 202 can be fixed. At the same time, in the process of the mounting plate 202 moving, the pressure in the space on the side of the mounting plate 202 close to the first magnet 303 in the sleeve 201 is reduced, and when the mounting rod 203 is inserted into the fixing groove 405 During the process, the second through hole 506 is driven to communicate with the first through hole 505. At this time, the space in the sleeve 201 located on the side of the mounting plate 202 close to the first magnet 303 sucks air from the cavity 502 through the first through hole 505, the second through hole 506, and the first air pipe 504, and the cavity 502 is restored. At this time, the first elastic telescopic rod 204 drives the clamping plate 501 to fit with the artwork, and then the clamping plate 501 and the artwork are tightly adsorbed together under the action of the pressure in the cavity 502, so that when the artwork drives the first elastic telescopic rod 20 During the reciprocating process, the clamping plate 501 can always be adsorbed together with the artwork, effectively preventing the artwork from being tilted and damaged. In addition, in order to improve the fitting effect between the clamping plate 501 and the artwork, an elastic pad can be provided on the side of the clamping plate 501 away from the first elastic telescopic rod 204. When the clamping plate 501 contacts the artwork, the elastic pad will deform to fit closely with the artwork, thereby ensuring that the artwork and the clamping plate 501 fit closely. At the same time, the provision of the elastic pad can also reduce the wear of the artwork, further improving the protection effect of the artwork.

[0028] When the mounting plate 202 squeezes the third spring 404, the airflow in the space on the side of the mounting plate 202 away from the first magnet 303 in the sleeve 201 flows into the cavity 502 through the second air pipe 507 and the first air pipe 504, and blows toward the surface of the artwork through the air hole 503 on the cavity 502, so that dust particles on the surface of the artwork can be cleaned, thereby preventing excessive dust particles from adhering to the surface of the artwork and affecting the fitting effect between the clamping plate 501 and the artwork, resulting in the clamping plate 501 and the artwork being unable to be adsorbed together. Then, when the fixing rod 402 drives the second through hole 506 to connect with the first through hole 505, the fixing rod 402 drives the blocking plate 508 to block the second air pipe 507, thereby ensuring that the clamping plate 501 and the artwork are adsorbed together.

[0029] A support plate 601 is horizontally slidably installed on the bottom wall of the box body 1, and a buffer spring 602 is installed between the side wall of the support plate 601 and the box body 1. An air cylinder 603 is installed on the box body 1, and a locking rod 604 is slidably installed in the air cylinder 603. A locking groove 605 cooperating with the locking rod 604 is opened on the support plate 601, and a return spring 606 is installed between the locking rod 604 and the air cylinder 603. A third air pipe 607 connected with the sleeve 201 is inserted into the air cylinder 603.

[0030] By adopting the above technical solution, during the process of the mounting plate 202 squeezing the first spring 305, the space in the sleeve 201 located on the side of the mounting plate 202 close to the first magnet 303 draws air from the air cylinder 603 through the third air pipe 607, and causes the locking rod 604 to squeeze the reset spring 606 along the air cylinder 603. During the process of the locking rod 604 squeezing the reset spring 606, the locking rod 604 is disengaged from the locking groove 605, and then drives the support plate 601 to swing back and forth during the swinging of the artwork. At this time, the buffer spring 602 can further reduce the impact force on the artwork, and the support plate 601 swings with the artwork, which can reduce the wear on the bottom of the artwork, and further improve the protection effect of the artwork.

[0031] When the cover plate 301 drives the vertical plate 302 upward and disengages from the vertical slot, the second spring 401 stretches and drives the first magnet 303 to move away from the mounting plate 202, and drives the push rod 403 to disengage from the inclined slot during the movement of the first magnet 303. At this time, the third spring 404 drives the fixing rod 402 to return to its original position and disengage from the fixing slot 405, and drives the blocking plate 508 to disengage from the second air pipe 507 during the process of the fixing rod 402 returning to its original position, and drives the second through hole 506 to disengage from the first through hole 505 during the process of the fixing rod 402 returning to its original position. Then, the first spring 305 stretches and drives the mounting plate 202 to return to its original position. At the same time, the first elastic telescopic rod 204 stretches The first spring 305 extends and drives the clamping plate 501 to gradually break away from contact with the artwork. At the same time, during the process of the first spring 305 extending and driving the mounting plate 202 to reset, the airflow in the space of the sleeve 201 on the side of the mounting plate 202 close to the first magnet 303 is squeezed and flows into the air cylinder 603 through the third air pipe 607. Then the reset spring 606 extends and drives the locking rod 604 to move upward. During the process of the locking rod 604 moving upward, it is inserted into the locking groove 605 again, so that the support plate 601 can be locked to prevent the support plate 601 from shaking and causing the artwork to tilt and collide with each other and cause damage when the user takes the artwork, thereby further improving the protection effect of the artwork.

[0032] The limiting assembly 7 includes a limiting rod 701 slidably mounted on the side wall of the box body 1 , a fourth spring 702 is installed between the limiting rod 701 and the box body 1 , and a limiting groove 703 cooperating with the limiting rod 701 is formed on the vertical plate 302 .

[0033] By adopting the above technical solution, when it is necessary to cover the cover plate 301, the user first pulls the limit rod 701, and then when the vertical plate 302 drives the limit groove 703 to contact the limit rod 701, the fourth spring 702 contracts and drives the limit rod 701 to insert into the limit groove 703, so that the cover plate 301 can be fixed to prevent the cover plate 301 from falling off and affecting the fixing effect of the artwork.

[0034] Working principle: When in use, first place the artwork in the box body 1, and make the artwork located between the corresponding first elastic telescopic rod 204 and the second elastic telescopic rod 205, then cover the cover plate 301 on the box body 1, and in the process of the cover plate 301 covering the top wall of the box body 1, the cover plate 301 drives the vertical plate 302 to move downward along the vertical groove, and in the process of the vertical plate 302 moving downward, drives the second magnet 304 to gradually approach the first magnet 303, and then the repulsive force between the first magnet 303 and the second magnet 304 gradually increases, and then under the action of the repulsive force, the first magnet 303 drives the mounting plate 202 to move along the sleeve 201, at this time, the first spring 305 is compressed and has a tendency to recover, and in the process of the mounting plate 202 moving ... The first elastic telescopic rod 204 is driven by the mounting rod 203 to gradually move toward the second elastic telescopic rod 205. During the movement of the first elastic telescopic rod 204, the artwork is driven to compress the second elastic telescopic rod 205. At this time, the first elastic telescopic rod 204 and the second elastic telescopic rod 205 are both compressed and have a tendency to recover. Then, the artwork can be clamped under the action of the elastic force of the first elastic telescopic rod 204 and the second elastic telescopic rod 205, thereby avoiding damage caused by tilting and collision during transportation of the artwork. During the movement of the mounting plate 202, the pressure in the space on the side of the mounting plate 202 close to the first magnet 303 in the sleeve 201 is reduced, and when the mounting rod 203 is inserted During the process of fixing the groove 405, the second through hole 506 is driven to communicate with the first through hole 505. At this time, the space in the sleeve 201 located on the side of the mounting plate 202 close to the first magnet 303 sucks air from the cavity 502 through the first through hole 505, the second through hole 506, and the first air pipe 504, and the cavity 502 is restored. At this time, the first elastic telescopic rod 204 drives the clamping plate 501 to fit with the artwork, and then the clamping plate 501 and the artwork are tightly adsorbed together under the action of the pressure in the cavity 502, so that the clamping plate 501 can always be adsorbed together with the artwork during the process of the artwork driving the first elastic telescopic rod 204 to extend and retract back and forth; when the mounting plate 202 squeezes the first elastic telescopic rod 204, the clamping plate 501 can be adsorbed together with the artwork. During the process of the three springs 404, the airflow in the space on the side of the mounting plate 202 away from the first magnet 303 in the sleeve 201 flows into the cavity 502 through the second air pipe 507 and the first air pipe 504, and blows toward the surface of the artwork through the air holes 503 on the cavity 502, so that dust particles on the surface of the artwork can be cleaned, thereby preventing excessive dust particles from adhering to the surface of the artwork and affecting the fitting effect between the clamping plate 501 and the artwork, resulting in the clamping plate 501 and the artwork being unable to be adsorbed together. Then, when the fixing rod 402 drives the second through hole 506 to communicate with the first through hole 505, the fixing rod 402 drives the blocking plate 508 to block the second air pipe 507;During the process of the mounting plate 202 squeezing the first spring 305, the space in the sleeve 201 located on the side of the mounting plate 202 close to the first magnet 303 draws air from the air cylinder 603 through the third air pipe 607, and causes the locking rod 604 to squeeze the return spring 606 along the air cylinder 603. During the process of the locking rod 604 squeezing the return spring 606, the locking rod 604 is disengaged from the locking groove 605, and then drives the support plate 601 to swing back and forth during the swinging of the artwork. At this time, the buffer spring 602 can further reduce the impact force on the artwork, and the support plate 601 swings with the artwork, which can reduce the wear degree of the bottom of the artwork. ;
