Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of paper towel racks, and particularly relates to a roll paper towel rack. BACKGROUND

[0002] The paper towel rack refers to a container made of a plastic or metal material shell, which is used for placing roll paper or folded paper, and is widely applied to hotels, homes and supermarkets and the like.

[0003] In the related art, a roll paper towel rack with a cover convenient to replace is disclosed in Chinese Patent No. CN204931547U, which comprises a connecting part for connecting with a wall surface, a rack body for hanging and placing roll paper towels, and a cover for shielding water and dust, the rack body is arranged on the connecting part, and the cover is rotatably and movably connected to the rack body. In use, the roll paper towels are hung on the upper horizontal cylindrical part of the rack body.

[0004] For the related art in the above, the inventors find that at least the following problem exists: Since the cover is shielded outside the roll paper towels hung on the rack body, when the roll paper towels are replaced, the operator needs to first turn the cover to the side away from the roll paper towels, and continuously control the position of the cover with one hand, so that the roll paper towels can be kept in an exposed state, and the other hand is used to replace the roll paper towels, which is inconvenient for single-handed replacement of the paper towels, and needs to be improved. SUMMARY

[0005] In order to facilitate single-handed replacement of the paper towels, the present application provides a roll paper towel rack.

[0006] The roll paper towel rack provided by the present application adopts the following technical scheme:

[0007] The roll paper towel rack comprises a support for connecting with a wall surface, a hanging rod arranged on the support for hanging and placing paper towels, and a cover arranged on the support for shielding water and dust, the cover is arranged above the paper towels hung on the hanging rod, the cover comprises a fixed plate arranged on the support and a movable plate slidably connected to the support, the movable plate has a first station for shielding the paper towels hung on the hanging rod and a second station for exposing the paper towels hung on the hanging rod, the fixed plate is provided with a locking piece for positioning the movable plate at the second station, and the movable plate is provided with an anti-disengagement piece for preventing the movable plate from being separated from the support.

[0008] By adopting the technical scheme, when the paper towel is hung on the hanging rod, the movable plate is at the first station, and plays a role of shielding water and dust for the paper towel. When the paper towel needs to be replaced, the movable plate is first moved to the second station, and then the locking piece is operated to position the movable plate at the second station, so that the paper towel is no longer shielded by the movable plate and is in an exposed state. Since the movable plate is not easy to move relative to the support under the action of the locking piece, the operator does not need to control the position of the shielding cover synchronously when replacing the paper towel, and single-handed operation is facilitated and the replacement efficiency is high.

[0009] In addition, during the movement of the movable plate relative to the support, the anti-disengagement piece can hinder the movable plate from being separated from the support, thereby helping to improve the integrity of the shielding cover.

[0010] Optionally, the locking piece comprises a base plate hinged to one side of the fixed plate facing the movable plate, a locking plate slidingly arranged on the base plate, and a locking spring for driving the locking plate to move away from the base plate, and a side wall of the movable plate facing the fixed plate is provided with a locking slot for the locking plate to extend into.

[0011] By adopting the technical scheme, when the movable plate moves to the second station, if the locking plate and the locking slot are in an aligned state, the locking plate will extend into the locking slot under the action of the locking spring. At this time, the locking spring has an action force on the locking plate in the direction of the movable plate, which has a certain pressing effect on the movable plate, so that the movable plate can be kept at the second station and is not easy to move randomly and will not interfere with the replacement of the paper towel.

[0012] After the replacement is completed, the movable plate is pulled away from the support, and the side wall of the locking slot will generate a pushing force on the locking plate, so that the locking plate drives the base plate to rotate towards the fixed plate. At the same time, the locking plate will compress the locking spring, and the locking plate will automatically move out of the locking slot, thereby realizing the quick unlocking of the movable plate.

[0013] Optionally, a resilient clamping block is arranged on one side of the locking plate facing the fixed plate, and a clamping slot is arranged on the fixed plate for clamping cooperation with the clamping block; a limiting magnet for controlling the rotation angle of the base plate is arranged on the fixed plate, and the base plate is a metal plate that can be attracted to the limiting magnet; when the base plate is rotated to abut against the limiting magnet, the locking plate is aligned with the locking slot on the movable plate at the second station.

[0014] By adopting the technical scheme, when no locking piece is used, the locking plate and the base plate can be rotated to the side close to the fixed plate, so that the clamping block is deformed and embedded in the clamping groove, so as to prevent the locking plate and the base plate from shaking at will when subjected to vibration and to prevent the locking plate and the base plate from interfering with the pulling of the paper towel. When the paper towel needs to be replaced, the movable plate is moved to the front of the second station, the base plate is first rotated to the side away from the fixed plate, and the base plate is abutted against and attracted to the limiting magnet. At this time, the limiting magnet can not only control the rotation angle of the base plate and the locking plate, but also improve the stability of the base plate and the locking plate, which is beneficial to the alignment of the locking plate and the locking groove.

[0015] Optionally, the support includes a mounting plate, a connecting rod fixed to one side of the mounting plate, and a cross rod fixed to the side of the connecting rod away from the mounting plate. An extension rod is fixed to the lower side of the cross rod, and an active hole for the movable plate to pass through is formed in the extension rod. The anti-disengagement piece includes anti-disengagement blocks arranged at both ends of the movable plate, and the width of the anti-disengagement block is greater than the width of the active hole.

[0016] By adopting the technical scheme, when the position state of the movable plate is changed, the operator only needs to push and pull the movable plate to make the movable plate slide along the active hole, which is simple in structure and convenient to operate. The anti-disengagement block prevents the movable plate from disengaging from the active hole, and the overall integrity of the shielding cover is good.

[0017] Optionally, the fixed plate is fixed with a rotating tube sleeved on the outer side of the cross rod. One end of the cross rod is fixed with a stop ring, and the other end is threadedly connected with a pressing nut for abutting the rotating tube against the stop ring.

[0018] By adopting the technical scheme, when the shielding cover is installed, the rotating tube is first sleeved on the cross rod and moved to abut against the stop ring, and then the pressing nut is screwed on the cross rod to press the rotating tube against the stop ring, so as to realize the stable connection of the fixed plate and the support. When the shielding cover is removed, the pressing nut is first unscrewed from the cross rod, and then the rotating tube is moved out of the cross rod, so that the shielding cover can be removed from the support, which is convenient for separately cleaning the shielding cover.

[0019] In addition, since the rotating tube is rotatably sleeved on the outer side of the cross rod, when shielding different sizes or shapes of the paper towel roll, the operator can first loosen the pressing nut, and then rotate the rotating tube relative to the cross rod, so as to realize the position adjustment of the shielding cover. After adjustment, the pressing nut is tightened again, so as to realize the relative fixation of the fixed plate and the support.

[0020] Optionally, the circumferential side wall of the rotating tube and the movable plate are fixedly connected with an elastic waterproof cloth. When the movable plate is in the first station, the connecting end of the waterproof cloth and the movable plate is located on the side of the active hole away from the mounting plate.

[0021] By adopting the technical scheme, the waterproof cloth can block water from flowing down from the gap formed by the rotating pipe and the movable plate, so as to prevent water from dropping on the paper towel and affecting the use of the paper towel. The waterproof cloth is made of elastic material, and can adaptively deform when the movable plate moves, without affecting the normal movement of the movable plate.

[0022] Optionally, the support further comprises a supporting plate fixed on the top of the mounting plate, and a storage box is detachably connected to the supporting plate, and a plurality of draining holes are arranged at the bottom of the storage box; a square frame is integrally formed on the lower side of the storage box, a square hole is formed in the supporting plate for vertically inserting the square frame, and a connecting groove horizontally extending is formed in the hole wall of the square hole on opposite sides; a connecting block is slidably arranged in the connecting groove; a through hole is formed in the side wall of the square frame on opposite sides for inserting the adjacent connecting block; and a connecting spring is arranged in the connecting groove for driving the connecting block to extend out of the connecting groove, and an upwardly inclined guide slope is arranged on the end of the connecting block away from the connecting spring.

[0023] By adopting the technical scheme, the storage box is detachably connected to the supporting plate, and can be used for placing paper towels, soap and other sundries, so as to enrich the functions of the paper towel holder. When the storage box is installed, the square frame is vertically inserted into the square hole, and in the process of moving downward, the square frame first abuts against the guide slope, and the connecting block is pushed back into the connecting groove, so that the connecting spring is compressed and elastically deformed. When the through hole moves to the position aligned with the connecting block, the connecting block automatically extends into the through hole under the action of the connecting spring, so as to prevent the square frame from moving out of the square hole, thereby realizing the stable connection between the storage box and the support, and the operation is simple.

[0024] Optionally, a pushing member is arranged on the storage box for driving the two connecting blocks to synchronously move out of the through holes, the pushing member comprises a bidirectional screw rod rotatably arranged on the square frame, and push rods are threadedly connected to different threaded segments of the bidirectional screw rod, the top end of the push rod is attached to the lower side of the storage box, the bottom end is aligned with the adjacent through hole, and the push rod can extend into the adjacent through hole under the action of the bidirectional screw rod, and a rotary nut is fixed to the middle part of the bidirectional screw rod.

[0025] By adopting the technical scheme, when the storage box is removed, the operator can rotate the rotary nut by using a wrench, so that the bidirectional screw rod rotates circumferentially, and then drives the two push rods to synchronously move backward, so that the push rod pushes the adjacent connecting block out of the through hole, thereby releasing the locking of the connecting block to the square frame. The present application can synchronously drive two push rods to move by using one bidirectional screw rod, so as to realize the synchronous unlocking of the two connecting blocks, and the removal efficiency of the storage box is high.

[0026] Optionally, the hanging rod comprises a connecting portion fixed on the support, a hanging portion integrally formed on the connecting portion for hanging the paper towel, and a limiting portion provided at one end of the hanging portion away from the connecting portion, the limiting portion comprising a base provided on the hanging portion, a limiting rod slidingly connected to the base, and a limiting spring for driving the limiting rod to move away from the base, and one end of the limiting rod away from the base is provided with a guide round corner.

[0027] By adopting the above technical scheme, when the paper towel is hung on the hanging rod, the limiting rod is in the state of extending out of the base under the action of the limiting spring, and the paper towel on the hanging portion is blocked by the limiting rod and is not easy to fall off from the hanging rod when being pulled by people, so that the stability is high. The guide round corner plays a guiding role when the roll of paper towel is moved into or out of the hanging portion, so that the operator does not need to control the position of the limiting rod synchronously when replacing the paper towel, and the operation is more convenient.

[0028] Optionally, the side of the hanging portion facing the base is fixed with a connecting ball, an optimal arc groove is formed in the base and is in rotational cooperation with the connecting ball, a rubber pad is fixed on the groove wall of the optimal arc groove, and the center of gravity of the connecting ball is located in the optimal arc groove.

[0029] By adopting the above technical scheme, the base can rotate relative to the hanging portion around the connecting ball, so that the axial direction of the base and the limiting rod is variable, so as to adapt to the requirement of limiting the paper towel at different positions. The rubber pad can increase the friction resistance between the connecting ball and the base, and helps to improve the stability of the base and the limiting rod.

[0030] In summary, the present application has at least one of the following beneficial technical effects:

[0031] 1. When the paper towel is hung on the hanging rod, the movable plate is in the first position for shielding the paper towel, and plays a role of shielding water and dust; when it is necessary to replace the paper towel, the movable plate is first moved to the second position for exposing the paper towel, and then the movable plate is positioned by the locking member, so that the paper towel can be replaced by one hand conveniently;

[0032] 2. When the base is rotated to abut against the limiting magnet, if the movable plate is moved to the second position, the locking plate is aligned with the locking groove, and at this time the locking plate extends into the locking groove under the action of the locking spring, so that the movable plate is not easy to shake; the waterproof cloth can block water from dripping along the gap between the rotating pipe and the movable plate to the paper towel, and is beneficial to normal use of the paper towel;

[0033] 3. When the storage box is installed on the supporting plate, it can be used for storing sundries such as soap, and after being installed in place, the square frame is embedded in the square hole, and the connecting blocks are located in the adjacent through holes, so that the stability of the storage box is high; when the storage box is removed, the bidirectional screw rod is rotated to move the two push rods away from each other, so that the push rod pushes the connecting block close to it out of the through hole, thereby achieving unlocking of the storage box, and the storage box is convenient to disassemble and assemble.

DETAILED DESCRIPTION

[0044] The following will be described in detail with reference to the accompanying drawings. Figures 1-8The application is further described in detail.

[0045] The application discloses a roll paper holder for hanging roll paper.

[0046] Referring to Figure 1 , the roll paper holder comprises a support 1, a hanging rod 2 arranged on the support 1 for hanging paper, and a cover 3 arranged on the support 1 for shielding water and dust for the paper, wherein the support 1 is fixedly connected to a wall surface in use, and the cover 3 is arranged above the paper hung on the hanging rod 2.

[0047] Referring to Figure 1 , the support 1 comprises a mounting plate 11 for connecting to the wall surface, a supporting plate 12 fixed to the top of the mounting plate 11, a connecting rod 13 fixed to the side of the mounting plate 11 away from the wall surface, and a horizontal rod 14 fixed to the side of the connecting rod 13 away from the mounting plate 11, and the cover 3 is detachably arranged on the horizontal rod 14.

[0048] Referring to Figure 2 , Figure 3 , the supporting plate 12 is detachably provided with a storage box 4, and the bottom of the storage box 4 is provided with a plurality of water draining holes 41 for draining water in the storage box 4 to prevent a large amount of water from accumulating in the storage box 4. The lower side of the storage box 4 is integrally formed with a square frame 42, and the middle of the supporting plate 12 is provided with a square hole 121 for vertically inserting the square frame 42, so as to realize the insertion connection of the storage box 4 and the supporting plate 12.

[0049] Referring to Figure 3 , Figure 4 , in order to prevent the square frame 42 from being easily pulled out of the square hole 121, a horizontally extending connecting groove 122 is arranged on the hole wall of each of the two opposite sides of the square hole 121, a connecting spring 123 is fixed to the groove wall of the connecting groove 122 away from the opening of the connecting groove 122, a connecting block 124 is fixed to the other end of the connecting spring 123, and an upwardly inclined guide inclined surface 125 is arranged on the end of the connecting block 124 away from the connecting spring 123. When the connecting spring 123 is in a natural state, the guide inclined surface 125 is located outside the connecting groove 122. The two opposite side walls of the square frame 42 are respectively provided with a through hole 421 for inserting the adjacent connecting block 124, and when the storage box 4 is installed, the square frame 42 is vertically inserted into the square hole 121, and the connecting block 124 is automatically embedded into the adjacent through hole 421 under the action of the connecting spring 123, so as to limit the upward movement of the square frame 42 relative to the supporting plate 12, thereby realizing the quick installation of the storage box 4.

[0050] Referring to Figure 3 , Figure 4The storage box 4 is equipped with a pusher 5 for driving two connecting blocks 124 to move synchronously out of the through hole 421. The pusher 5 includes a bidirectional lead screw 51 rotatably mounted on the square frame 42 and two push rods 52 respectively threaded to different threaded sections of the bidirectional lead screw 51. The two ends of the bidirectional lead screw 51 are respectively rotatably connected to two opposite side walls of the square frame 42. To further improve the stability of the bidirectional lead screw 51, a support block 43 is fixed on the lower side of the storage box 4 for the bidirectional lead screw 51 to rotate through. There are two support blocks 43, which are spaced apart along the axial direction of the bidirectional lead screw 51.

[0051] Reference Figure 4 In this embodiment, the push rod 52 is L-shaped, with its top end fitting against the lower side of the storage box 4 and its bottom end aligned with the adjacent through hole 421. A screw-on nut 53 is fixed to the middle of the bidirectional lead screw 51. When removing the storage box 4, the operator can use a wrench to rotate the screw nut, thereby causing the bidirectional lead screw 51 to rotate relative to the square frame 42. This causes the two push rods 52 to move synchronously in opposite directions and extend into the adjacent through hole 421, thus using the push rods 52 to push the connecting block 124 back into the connecting groove 122, thereby releasing the lock on the square frame 42.

[0052] Reference Figure 3 , Figure 5 The suspension rod 2 includes a connecting part 21 fixed to the side of the mounting plate 11 away from the wall, a suspension part 22 integrally formed on the connecting part 21, and a limiting part 23 rotatably disposed at the end of the suspension part 22 away from the connecting part 21. The limiting part 23 includes a base 231, a limiting rod 232 slidably connected to the base 231, and a limiting spring 233 for driving the limiting rod 232 to move away from the base 231. Specifically, the connection structure between the limiting rod 232 and the base 231 is as follows: a groove 234 extending along its own axial direction is provided on the base 231, one end of the limiting rod 232 is slidably disposed in the groove 234, one end of the limiting spring 233 is fixed to the limiting rod 232, and the other end is fixed to the groove wall of the groove 234 away from its own opening, and the extension direction of the limiting spring 233 is parallel to the axial direction of the limiting rod 232. When the limiting spring 233 is in its natural state, one end of the limiting rod 232 is located outside the base 231, which prevents the tissue from moving out of the hanging part 22. If the tissue needs to be replaced, simply press the limiting rod 232 towards the side closer to the base 231 to compress and deform the limiting spring 233, and then move the tissue into or out of the hanging part 22. The operation is simple.

[0053] Reference Figure 5 To facilitate the replacement of tissues, a guide rounded corner 235 is provided at the end of the limiting rod 232 away from the base 231. The guide rounded corner 235 plays a guiding role when the tissue roll moves into or out of the hanging part 22, which helps to improve the efficiency of tissue replacement.

[0054] With reference to Figure 5 , the suspension part 22 is fixed with a connecting ball 221 on one side thereof facing the base 231, the base 231 is provided with an optimal arc groove 236 which is in rotational cooperation with the connecting ball 221, the groove wall of the optimal arc groove 236 is fixed with a rubber pad 237, and the center of gravity of the connecting ball 221 is located in the optimal arc groove 236, so as to realize the rotational connection between the limiting part 23 and the suspension part 22.

[0055] With reference to Figure 2 , the shielding cover 3 comprises a fixed plate 31 arranged on the support 1 and a movable plate 32 which is slidingly connected to the support 1, the movable plate 32 in the embodiment is in an arc shape, and the side surface of the movable plate 32 facing the suspension rod 2 is a concave arc surface. The fixed plate 31 is fixed with a rotating tube 33 at the end thereof away from the mounting plate 11, and the rotating tube 33 is rotatably sleeved on the outer side of the cross rod 14. In order to limit the rotation of the rotating tube 33 relative to the cross rod 14, the cross rod 14 is fixed with a stop ring 141 at one end thereof close to the connecting rod 13, and is threadedly connected with a pressing nut 142 at the other end, and the pressing nut 142 can press the rotating tube 33 against the stop ring 141.

[0056] With reference to Figure 6 , Figure 7 , the lower side of the cross rod 14 is fixed with an extension rod 143, the extension rod 143 is provided with a movable hole 144 for the movable plate 32 to slidingly pass through, and the movable plate 32 can slide along the movable hole 144 to a first station 6 for shielding the paper towels hung on the suspension rod 2 and a second station 7 for exposing the paper towels hung on the suspension rod 2.

[0057] With reference to Figure 6 , in order to prevent the movable plate 32 from being separated from the support 1 during sliding, the movable plate 32 is provided with an anti-separation piece 8, and the anti-separation piece 8 comprises anti-separation blocks 81 arranged at both ends of the movable plate 32 along the sliding direction thereof, and the width of the anti-separation blocks 81 is greater than the width of the movable hole 144, so that the movable plate 32 cannot be separated from the movable hole 144.

[0058] With reference to Figure 7 , Figure 8The fixed plate 31 is provided with a locking piece 9 for positioning the movable plate 32 in the second station 7. The locking piece 9 comprises a base plate 91 hinged to one side of the fixed plate 31 facing the movable plate 32, a locking plate 92 slidingly arranged on the base plate 91, and a locking spring 93 for driving the locking plate 92 to move away from the base plate 91. The base plate 91 is provided with a base groove 911 for slidingly arranging the locking plate 92, and the locking spring 93 is fixedly connected between the locking plate 92 and the groove wall of the base groove 911. The side wall of the movable plate 32 facing the fixed plate 31 is provided with a locking groove 321 for extending the locking plate 92. After the movable plate 32 is moved to the second station 7, the locking plate 92 can be extended into the locking groove 321, and the locking spring 93 has an acting force on the locking plate 92 towards the movable plate 32, which helps to improve the stability of the movable plate 32.

[0059] With reference to Figure 8 To facilitate the alignment of the locking plate 92 and the locking groove 321, a limiting magnet 311 is arranged on the lower side of the fixed plate 31, and the limiting magnet 311 is located on the side of the base plate 91 facing the mounting plate 11, which plays a role in controlling the rotation angle of the base plate 91. When the base plate 91 is rotated to abut against the limiting magnet 311, the locking plate 92 is aligned with the locking groove 321 on the movable plate 32 in the second station 7, which is conducive to the rapid positioning of the movable plate 32. To further improve the stability of the base plate 91 when it abuts against the limiting magnet 311, the base plate 91 in the embodiment is made of a metal plate that can be attracted to the limiting magnet 311.

[0060] With reference to Figure 8 The side of the locking plate 92 facing the fixed plate 31 is fixedly provided with a clamping block 921 made of a material capable of elastic deformation, and the lower side of the fixed plate 31 is provided with a clamping groove 312 matched with the clamping block 921. When the locking piece 9 is not used, the operator can rotate the locking plate 92 towards the fixed plate 31, so that the clamping block 921 is embedded in the clamping groove 312, thereby preventing the locking plate 92 and the base plate 91 from shaking.

[0061] With reference to Figure 6 To prevent water from accumulating on the shielding cover 3 when dripping from the draining hole 41, a water guide hole 111 is formed in the mounting plate 11, and the bottom end of the water guide hole 111 is flush with the end of the fixed plate 31 close to the mounting plate 11. When the water in the storage box 4 drips onto the fixed plate 31, the water will flow along the fixed plate 31 to the water guide hole 111 to be discharged from the paper towel holder. In addition, a waterproof cloth 34 made of an elastic material is fixedly connected between the circumferential side wall of the rotating tube 33 and the movable plate 32. When the movable plate 32 is in the first station 6, the connecting end of the waterproof cloth 34 is located on the side of the movable hole 144 away from the mounting plate 11, and the waterproof cloth 34 can prevent water from dripping onto the paper towel through the gap between the rotating tube 33 and the movable plate 32.

[0062] The implementation principle of the paper roll holder according to an embodiment of the present application is as follows: when replacing the paper roll, the locking plate 92 is first rotated away from the fixed plate 31 until the base plate 91 is rotated to abut against and be attracted to the limiting magnet 311, and then the movable plate 32 is pushed to the second station 7 close to the mounting plate 11. After the movable plate 32 is moved into position, the locking plate 92 is embedded into the locking groove 321 under the action of the locking spring 93 to position the movable plate 32 at the second station 7, and then the paper roll is horizontally sleeved on the hanging portion 22. During the movement of the paper roll, the limiting rod 232 first compresses the limiting spring 233 to provide space for sleeving the paper roll on the hanging portion 22, and then the limiting rod 232 is automatically reset under the action of the limiting spring 233 to block the paper roll from moving out of the hanging portion 22. Finally, the movable plate 32 is pulled away from the mounting plate 11, so that the locking plate 92 is automatically moved out of the locking groove 321, and then the locking plate 92 is rotated toward the fixed plate 31 until the clamping block 921 is embedded into the clamping groove 312. The above-mentioned operation of replacing the paper roll can be realized by an operator using one hand, and the paper roll is convenient to replace.

[0063] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
