Description

Technical Field

[0001] The invention relates to a cover opening and closing structure, in particular to a cover opening and closing structure for a coating tool. Background Art

[0002] With the recent development of online shopping, a large number of goods are delivered to consumers by express delivery. After receiving the express delivery, consumers usually throw away the packaging such as cartons. However, since personal information such as addresses are printed on the packaging, the part with personal information needs to be processed. As such a processing device, a rolling stamp with a protective cover that can be rotated to open is previously known as described in Patent Document 1.

[0003] Patent document 1: CN201810892121.X

[0004] In Patent Document 1, the user turns the protective cover by hand to expose the stamp portion covered by the protective cover. However, when the user opens the protective cover by hand, the user needs to use his fingers to turn the protective cover from the closed state to the open state. In this process, the fingers may rub against the stamp, and the fingers may be dirty, which brings great trouble to the user. Summary of the invention

[0005] An object of the present invention is to provide a cover opening and closing structure in which a user is less likely to touch a covered object.

[0006] A hood opening and closing structure of one embodiment of the present invention opens and closes a hood covering a covered portion, and comprises: a moving mechanism for moving the hood between an open position and a closed position; a hood force applying component for applying force to the hood in an opening direction; a locking mechanism for locking the hood in a closed position; and an operating component for releasing the lock of the locking mechanism to allow the force applying component to move the hood to the open position.

[0007] Preferably, a portion of the locking mechanism is formed integrally with the operating member.

[0008] Preferably, the operating member extends in one direction, has an operating portion at one end, and has a part of the locking mechanism at the other end.

[0009] Preferably, the operating member is rotatable about a support shaft provided between the operating portion and a part of the locking mechanism.

[0010] A lock urging member is further provided for urging the operating member so as to maintain a part of the lock mechanism in a locked state.

[0011] Preferably, the moving mechanism includes a support portion that rotatably supports the cover, and a transmission portion that moves the cover to the open position via the cover urging member.

[0012] Preferably, the covered portion is a holding portion for holding ink transferred to the object.

[0013] A coating tool according to another embodiment of the present invention comprises: a holding portion having a holding surface for holding a coating agent, wherein the holding surface can abut against an object; a shell that holds the holding portion in a manner such that at least a portion of the holding surface can be exposed to the outside; a cover that is supported by the shell in an openable and closable manner and can be in an open posture in which the holding surface is exposed and a closed posture in which the holding surface is covered; a moving mechanism that moves the cover between an open posture and a closed posture; a cover force applying component that applies force to the cover toward the open posture side; a locking mechanism that locks the cover in the closed posture; and an operating component for releasing the lock of the locking mechanism, thereby allowing the cover force applying component to move the cover toward the open posture side.

[0014] Preferably, the operating member has an operating portion that can be sunken into the surface of the housing when the locking mechanism is unlocked, and the operating portion does not protrude from the housing surface when the locking mechanism is locked. Since the operating portion of the operating member does not protrude from the housing surface when the locking mechanism is locked, the operating portion is not easily pressed due to collision or the like to accidentally open the cover, thereby avoiding the cover being accidentally opened to expose the holding portion holding the coating agent.

[0015] Preferably, the locking mechanism includes: a first engaging portion provided on the cover; a second engaging portion engageable with and disengageable from the first engaging portion; and a lock urging member urging the second engaging portion in a direction to engage the first engaging portion.

[0028] Hereinafter, one embodiment of the present invention will be described with reference to the drawings. Figure 1 1 is a perspective view of a coating tool having an opening and closing mechanism according to an embodiment of the present invention. Figure 1 The description will be given by setting the upper side in “up”, the lower side in “down”, the left side in “left”, and the right side in “right”.

[0029] like Figure 1 As shown, the coating tool has a shell 4 that is roughly egg-shaped, and the shell 4 is composed of two parts: a first shell 41 and a second shell 42. An operating component 5 is provided on the left side of the shell 4. A cover 6 that can be opened and closed is provided at the lower part of the shell 4. Figure 2 As shown, a transfer roller 8 holding ink is rotatably housed in a lower portion of the housing 4 .

[0030] First, the housing 4 will be described. Figure 1As shown, the housing 4 has an opening at the lower left side for the operating component 5 to be arranged, and an opening at the lower part for the cover 6 to be arranged. Figure 4 As shown, the housing 4 also contains a transmission component 12 and a drive spring 12a for driving the cover 6, and has a structure for fixing and storing the above components. The second housing 42 is provided with a cylindrical connecting portion 421 and a connecting portion 428 for connecting it to the first housing 41. The second housing 42 is also provided with a partition wall 421 for separating the upper part of the housing 4 from the transfer roller 8, the transmission component 12, the drive spring 12a and other components. Although not illustrated in the present embodiment, other components can be installed in the space in the upper part of the housing 4, for example, a cutting tool for opening a courier can be installed. Because the structures of the first housing 41 and the second housing 42 are symmetrical to each other, a detailed description of the first housing 41 is omitted here.

[0031] Next, the operating component 5 will be described. Figure 1 As shown, a pressing portion 51 is formed on the upper side of the operating member 5, and the pressing portion 51 is recessed toward the inner side of the housing 4. A first engaging portion 52a and a second engaging portion 52b are formed on the lower side of the operating member 5. Figure 3 As shown, the operating member 5 has a rectangular plate-shaped baffle portion 55 at the upper portion. A cylindrical boss portion 53 is formed inside corresponding to the pressing portion 51. A support shaft 54a and a support shaft 54b are formed on both sides of the middle portion of the operating member 5, respectively.

[0032] like Figure 4 As shown, the operating member 5 is rotatably supported on the housing 4 by the support shaft 54a and the support shaft 54b. A locking spring 58 is provided between the operating member 5 and the housing 4. The locking spring 58 is a coil spring. One end of the locking spring 58 is fixed to the housing 4, and the other end is sleeved on the protrusion 53. The locking spring 58 applies force to the operating member 5 outward. Because the upper part of the operating member 5 is always subjected to the elastic force of the locking spring 58, the lower part of the operating member 5, i.e., the first engaging portion 52a and the second engaging portion 52b, applies force to the inner side of the housing 4, so that the engaging state with the third engaging portion 64a and the fourth engaging portion 64b of the cover 6 described later can be stably maintained.

[0033] In addition, due to the presence of the baffle portion 55, although the operating member 5 is subjected to the outward force applied by the locking spring 58, it does not protrude to the outside of the housing 4. Therefore, when the coating tool is stored in a bag or other storage container, because the operating member 5 does not protrude relative to the housing 4, especially the pressing portion 51 is recessed inwardly relative to the housing 4 and the operating member 5, it is not easy to cause the cover 6 to be accidentally opened due to misoperation, and the transfer roller 8 is exposed, thereby soiling the bag or other storage container.

[0034] Next, refer to Figure 1 and Figure 4 The structure of the cover 6 is described. Since the cover 6 has a symmetrical structure between the front side and the rear side, the front side is mainly described below, and the detailed description of the rear side is omitted. The cover 6 has a hollow cover body 61 that is roughly semicircular, and a holding portion 63 that protrudes to the left is provided on the left side of the cover body 61. A third engaging portion 64a is formed on the front side of the holding portion 63, and although not shown in the accompanying drawings, a fourth engaging portion 64b is also symmetrically formed on the rear side of the holding portion 63. A gear portion 62 and a cylindrical protrusion 65 are provided at the position of the rotation center of the surface of the front side of the cover 6, and a corresponding structure is also formed on the rear side of the cover 6. The cover 6 is rotatably fixed to the housing 4 through the protrusion 65 and the protrusion on the other side that is not shown.

[0035] The transfer roller 8 is freely rotatably accommodated in the cover 6, and its surface is made of a material that can absorb ink. The surface of the transfer roller 8 can be flat or have a grid pattern. In addition, the surface of the transfer roller 8 can also be randomly formed with Chinese characters and numbers similar to the personal information on the express package, which can effectively hide the personal information on the express package and reduce the amount of ink used.

[0036] In this embodiment, drive mechanisms are provided on both the left and right sides of the cover 6. Since the structures of the drive mechanisms on both sides are the same, the drive mechanism on one side of the first housing 41 will be mainly described, and the description of the drive mechanism on the other side will be omitted. Figure 4 As shown, the driving mechanism includes a driving spring 12a and a transmission component 12. The driving spring 12a is a coil spring. Figure 4 One end of the driving spring 12a is fixed to a protrusion of the first housing 41 (not shown), which is symmetrical with the protrusion 424 of the second housing 42 and has the same shape. The other end of the driving spring 12a is fixed to the hole 123 of the transmission component. In addition, the first housing 41 also has a guide portion corresponding to the guide portion 423 of the second housing 42, which is used to guide the driving spring 12a so that it can be stretched and contracted smoothly in the housing 4. The transmission component 12 has a hole 121, a hole 123 and a tooth portion 122. The transmission component 12 can be rotatably fixed to the protrusion of the first housing 41 (not shown) through the hole 121. As described above, the transmission component 12 is connected to the driving spring 12a through the hole 123, so that it can be affected by the elastic force of the driving spring 12a. The transmission component 12 is meshed with the gear 62 formed on the cover 6 through the tooth portion 122, so that the elastic force of the driving spring 12a is transmitted to the cover 6.

[0037] like Figure 4As shown, in the closed state, the drive spring 12a is in a stretched state, exerting a force on the transmission component 12 to rotate it clockwise, and the transmission component 12 transmits the force from the drive spring 12a to the cover 6, exerting a force on the cover 6 in the opening direction. Similarly, the drive mechanism (not shown) located at the rear side also exerts a force on the cover 6 in the opening direction.

[0038] like Figure 5 As shown, in the open state, the driving mechanism urges the cover 6 via the driving spring 12a and the driving spring 12b (not shown), whereby the cover 6 maintains the state in which the gripping portion 63 abuts against the housing 4, that is, the transfer roller 8 is exposed.

[0039] Next, the operation of the coating tool is described. Figure 4 The operation of opening the cover 6 in the closed state shown will be described.

[0040] The user presses the pressing portion 51 with a finger, and overcomes the elastic force of the locking spring 58 to press the pressing portion 51, i.e., the upper side of the operating member 5, so that the lower side of the operating member 5 rises, and the first engaging portion 52a and the second engaging portion 52b of the operating member 5 respectively separate from the third engaging portion 64a and the fourth engaging portion 64b of the cover 6, thereby releasing the lock. At this time, as described above, in the closed state, since the drive spring 12a on one side of the first shell 41 and the unillustrated drive spring 12b on the other side are in a stretched state, a force is applied to the cover 6 to rotate in the opening direction through the drive mechanism, so after the lock is released, the cover 6 moves in the opening direction due to the elastic force of the drive spring 12a and the unillustrated drive spring 12b, thereby exposing the transfer roller 8, becoming and maintaining Figure 2 as well as Figure 5 The cover 6 is in the open state shown. In this state, the user can hide the personal information by pressing the transfer surface of the transfer roller 8 against the portion of the package that needs to be hidden where the personal information is printed or written, and rolling the transfer roller 8 to cover the portion of the package where the personal information is printed with ink. Because the user only needs to press the pressing portion 51 to open the cover 6 and expose the transfer roller 8. Therefore, when it is necessary to use a coating tool to hide various information, the transfer roller 8 can be exposed immediately, and the work of hiding the personal information with the transfer roller 8 can be carried out immediately. In addition, during the opening process, because the user's hand does not need to be close to the transfer roller 8, the user's hand is not easy to touch the transfer roller 8, and therefore is not easy to be stained by the ink on the transfer surface of the transfer roller 8.

[0041] Next, from Figure 5The action of closing the cover 6 in the open state shown is explained. After using the coating tool to cover the personal information on the express delivery, the user holds the holding portion 63 of the cover 6 by hand and applies force in the closing direction, thereby overcoming the elastic force of the drive spring 12a and the drive spring 12b to rotate the cover 6 in the closing direction. After the third engaging portion 64a and the fourth engaging portion 64b respectively abut against the first engaging portion 52a and the first engaging portion 52b, force is continued to be applied to the holding portion 63 in the closing direction, thereby overcoming the force of the locking spring 58 to cause the first engaging portion 52a and the first engaging portion 52b to tilt up. After the first engaging portion 52a and the second engaging portion 52b are tilted up, the third engaging portion 64a and the fourth engaging portion 64b pass over the first engaging portion 52a and the second engaging portion 52b and engage with the first engaging portion 52a and the second engaging portion 52b to become Figure 1 as well as Figure 4 In the above operation, since the user's hand holding the gripping portion 63 needs to overcome the elastic force of the driving spring 12a and the driving spring 12b to move the cover 6 in the closing direction, it is more convenient for the user to apply force from the side of the gripping portion 63 opposite to the transfer roller 8, so it is not easy to touch the transfer roller 8 and not easy to dirty the hand.

[0042] The present invention is not limited to the above-mentioned embodiment, and various modifications and changes can be made to the present invention without departing from the scope of the main purpose of the present invention. For example, in the above-mentioned embodiment, the situation where the transfer roller 8 is held with ink is described, but the transfer roller 8 can also be held with an adhesive such as glue.

[0043] According to the present invention, a cover opening and closing structure having a simple structure, convenient operation, and in which a user is unlikely to touch a covered object, and a coating tool having the cover opening and closing structure can be provided.
