Description
Technical Field
[0001] The utility model relates to the technical field of dust dusters, in particular to an angle adjustment structure of a dust duster. Background Art
[0002] A duster is a commonly used cleaning product. Existing dusters can be used to clean various furniture, electrical appliances, walls, etc., and can brush away dust on the surfaces of objects.
[0003] When cleaning the top of furniture, the existing dust duster needs to adjust the angle of the dust duster to reach corners, bevels and other places that are difficult to clean. The existing dust duster has the function of changing the angle, but this function generally tends to store the dust duster or only adds a simple vertical position to the storage. It is still limited to use in some scenes and cannot meet the usage needs of different scenes. Utility Model Content
[0004] The purpose of the utility model is to provide an angle adjustment structure for a dust duster, which solves the problem that the angle adjustment function of a traditional dust duster cannot meet the needs of multiple scenarios.
[0005] To achieve the above purpose, the present invention provides the following technical solutions:
[0006] A dust duster angle adjustment structure includes a handle and a front fork, the handle and the front fork are rotationally connected, and a hovering gear is provided at the rotational connection, the hovering gear enables the front fork to hover at multiple angles relative to the handle, the hovering gear includes a first rotating part and a second rotating part that are hinged to each other, the first rotating part is connected to one end of either the handle or the front fork, the second rotating part is connected to the other end of the handle or the front fork, at least two mother parts are provided on the first rotating part, and the second rotating part is provided with a child part that is clamped to any mother part, and the handle and the front fork have mother parts and child parts clamped to each other when in use so as to hover.
[0007] By adopting the above technical solution: the dust duster has a handle for holding and a front fork for installing the duster body. Then, a hovering gear is set on the dust duster. The rotation angle of the front fork on the dust duster can be flexibly adjusted through the hovering gear, so that the front fork can hover continuously at multiple angles to meet the user's usage needs in different scenarios.
[0008] The mother component adopts a groove, which is a continuous tooth groove structure. The child component adopts a tooth block, which is arranged on the outer facade of the second rotating part, and the groove is arranged on the inner facade of the first rotating part. The groove rotates with the tooth block.
[0009] By adopting the above technical solution: the first rotating part and the second rotating part are hinged, and the front fork is suspended by cooperating with the tooth block and the groove, that is, the first rotating part and the second rotating part can be suspended at the same time when the handle and the front fork are unfolded, without the need to unfold the handle and the front fork first and then suspend the handle and the front fork by other means, which greatly improves the convenience of using the dust duster.
[0010] When the matching angle between the handle and the front fork is between 90° and 180°, there are corresponding tooth blocks and grooves between the handle and the front fork. When the tooth blocks and the grooves are engaged, the side surfaces of the tooth blocks abut against the inner walls of the grooves.
[0011] By adopting the above technical solution: the angle of the handle and the front fork can be adjusted from 90° to 180° through the cooperation of the tooth blocks and the grooves. Since there are corresponding grooves and tooth blocks for engagement at each angle, when the front fork is bent, the tooth blocks will disengage from the previous groove and continuously engage with the next groove. This arrangement avoids the situation where the entire front fork loses its limit and produces unstable shaking when the tooth blocks are disengaged from the corresponding grooves, resulting in an inability to continue using the dust duster. That is, the traditional dust duster requires the corresponding tooth blocks to be re-engaged in the grooves before it can continue to be used, which greatly reduces the cleaning efficiency. However, when the dust duster of this solution is used at 90° to 180°, when a tooth block disengages from the previous groove, there will still be another set of tooth blocks and grooves that are engaged with each other, thus avoiding the situation where the dust duster function fails.
[0012] Since this solution does not limit the number of grooves and tooth blocks that can be engaged, when the front fork is suspended at a certain angle, there will be multiple sets of tooth blocks and grooves that can be engaged. In any state of use, there are multiple sets of tooth blocks and grooves that can be engaged, which also ensures the stability of the front fork when in use.
[0013] The first rotating part and the second rotating part are both made of plastic.
[0014] The first rotating part is an arc-shaped plate bent at one end of the handle, and a rotating shaft is fixedly connected to the inner side of the arc-shaped plate. The second rotating part is a sleeve fixed at one end of the front fork, and the sleeve is sleeved with both ends of the rotating shaft. The groove is provided on the inner facade of the arc-shaped plate, and the tooth block is provided on the outer facade of the sleeve.
[0015] By adopting the above technical solution: the hovering gear is specifically coordinated by the arc plate and the shaft sleeve, the inner facade of the arc plate is provided with a groove, and the outer facade of the shaft sleeve is provided with a tooth block. When the front fork and the handle rotate relative to each other, the arc plate and the shaft sleeve also rotate relative to each other, so that the relative tooth blocks and the grooves are also disengaged and engaged.
[0016] Both ends of the rotating shaft extend outwards and are provided with threads. The rotating shaft penetrates the shaft sleeve and is connected to a fastening nut through threads.
[0017] By adopting the above technical solution: threads are set at both ends of the rotating shaft to connect the fastening nuts. By tightening the fastening nuts, the stability of the handle and the front fork in use can be enhanced after the grooves and the tooth blocks are engaged, thereby ensuring the use effect of the dust remover.
[0018] The end of the handle away from the front fork is connected to at least one connecting rod, and the end of the terminal connecting rod away from the front fork is connected to the tail vertebrae. The connecting rod and the handle, the connecting rod and the tail vertebrae, and the connecting rods are all connected through threads.
[0019] By adopting the technical solution, a connecting rod is used to lengthen the duster for use, thereby improving the use effect; and a tail vertebra is connected to one end of the connecting rod to decorate the connecting rod and protect the connecting part of the connecting rod from damage.
[0020] Anti-slip blocks are provided on the flanges on both sides of the front fork.
[0021] By adopting the above technical solution: an anti-slip block is provided to prevent the dusting cloth from slipping, thereby improving the use effect.
[0022] The technical effects and advantages of this utility model are:
[0023] 1. In this solution, the duster has a handle for holding and a front fork for installing the duster body. Then, a hovering gear is set on the duster. The rotation angle of the front fork on the duster can be flexibly adjusted through the hovering gear, so that the front fork can hover continuously at multiple angles to meet the user's usage needs in different scenarios.
[0024] 2. In this solution, the first rotating part and the second rotating part are hinged, and the front fork is suspended by cooperating with the tooth block and the groove, that is, the first rotating part and the second rotating part can be suspended at the same time when the handle and the front fork are unfolded, without having to unfold the handle and the front fork first and then suspend the handle and the front fork by other means, which greatly improves the convenience of using the dust duster.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0035] Example 1
[0036] This embodiment provides Figures 1 to 4 The angle adjustment structure of a dust duster shown in FIG. Figure 1 This is a diagram showing the duster in storage. Figure 2 It shows a schematic diagram of the dust remover in 180° use state. Figure 3 It shows a schematic diagram of the dust remover in the 120° use state. Figure 4 The diagram shows the dust remover in the 90° state. Figures 1 to 4 The structure shown is that the dust duster of this embodiment includes a handle 1 and a front fork 2, which are rotationally connected between the handle 1 and the front fork 2, and a hovering gear is provided at the rotational connection. The hovering gear enables the front fork 2 to hover at multiple angles relative to the handle 1, and the hovering gear includes a first rotating part and a second rotating part that are hinged to each other. The first rotating part is connected to one end of either the handle 1 or the front fork 2, and the second rotating part is connected to the other end of the handle 1 or the front fork 2. At least two mother parts are provided on the first rotating part, and the second rotating part is provided with a child part that is clamped to any mother part. When in use, the handle 1 and the front fork 2 have a mother part and a child part clamped to each other for hovering.
[0037] Furthermore, the dust duster has a handle 1 for holding and a front fork 2 for installing the duster body. Then, a hovering gear is set on the dust duster, and the rotation angle of the front fork 2 on the dust duster can be flexibly adjusted through the hovering gear, so that the front fork 2 can hover continuously at multiple angles to meet the user's usage needs in different scenarios.
[0038] Specifically, if Figures 5 to 7 As shown in any one of the figures, the mother component of this embodiment adopts a groove 301, which is a continuous tooth-groove structure, while the daughter component adopts a tooth block 401. Multiple tooth blocks 401 can be provided. The tooth block 401 is provided on the outer facade of the second rotating part, and the groove 301 is provided on the inner facade of the first rotating part. The groove 301 and the tooth block 401 rotate in conjunction. Among them, the first rotating part is a curved plate 3 provided at one end of the handle 1, and a rotating shaft 5 is fixedly connected to the inner side of the curved plate 3. The second rotating part is a sleeve 4 fixed to one end of the front fork 2, and the sleeve 4 is sleeved with both ends of the rotating shaft 5. The groove 301 is provided on the inner facade of the curved plate 3, and the tooth block 401 is provided on the outer facade of the sleeve 4. It can be seen that the hovering gear is specifically coordinated by the arc plate 3 and the sleeve 4. The inner surface of the arc plate 3 is provided with a groove 301, and the outer surface of the sleeve 4 is provided with a tooth block 401. When the front fork 2 and the handle 1 rotate relative to each other, the arc plate 3 and the sleeve 4 also rotate relative to each other, so that the relative tooth block 401 and the groove 301 are also disengaged and engaged.
[0039] Furthermore, an axle seat 6 is provided in the middle part of the inner side of the arc-shaped plate 3, and the axle seat 6 is used to install the rotating shaft 5. Then, the arc-shaped plate 3 and the shaft sleeve 4 of this embodiment are hinged by the rotating shaft 5, and the suspension of the front fork 2 is achieved by the cooperation of the tooth block 401 and the groove 301, that is, the first rotating part and the second rotating part can be suspended at the same time when the handle 1 and the front fork 2 are unfolded, without the need to unfold the handle 1 and the front fork 2 first and then achieve the suspension of the handle 1 and the front fork 2 by other means, which greatly improves the convenience of using the dust duster.
[0040] In order to meet the daily use needs of customers, this embodiment adopts the hovering structure in three use states of 90°, 120° and 180°. For details, please refer to Figures 2 to 4 .
[0041] It should be added that when the matching angle between the handle 1 and the front fork 2 is between 90° and 180°, there are corresponding tooth blocks 401 and grooves 301 between the handle 1 and the front fork 2. For details, please refer to the three usage states of the handle 1 and the front fork 2 at 90°, 120° and 180°. Figures 5 to 7The handle 1 and the front fork 2 are provided with corresponding tooth blocks 401 and grooves 301. When the tooth blocks 401 and grooves 301 are engaged, the side surfaces of the tooth blocks 401 abut against the inner walls of the grooves 301. To ensure that the tooth blocks 401 and grooves 301 can both engage and disengage, the first and second rotating parts of this embodiment are made of plastic, especially the tooth blocks 401 and grooves 301.
[0042] Furthermore, the cooperation between the tooth block 401 and the groove 301 can realize the angle adjustment of the handle 1 and the front fork 2 at 90° to 180°. Since there is a corresponding groove 301 and tooth block 401 for engagement at each angle, when the front fork 2 is bent, the tooth block 401 will disengage from the previous groove 301 and continuously engage into the next groove 301. This arrangement avoids the situation where the entire front fork 2 loses its restriction and produces unstable shaking when the tooth block 401 disengages from the corresponding groove 301, resulting in an inability to continue to use. That is, the traditional dust duster needs to re-engage the corresponding tooth block 401 into the groove 301 before it can continue to be used, which greatly reduces the cleaning efficiency. However, when the dust duster of this scheme is used at 90° to 180°, when a tooth block 401 disengages from the previous groove 301, there will still be another set of tooth blocks 401 and grooves 301 engaged with each other, thereby avoiding the situation where the dust duster function fails.
[0043] Since this solution does not limit the number of engagements between the grooves 301 and the tooth blocks 401, when the front fork 2 is suspended at a certain angle for use, there will be multiple sets of tooth blocks 401 engaged with the grooves 301. In any state of use, there are multiple sets of tooth blocks 401 engaged with the grooves 301, which also ensures the stability of the front fork 2 in use.
[0044] Example 2
[0045] The difference between this embodiment and embodiment 1 is that both ends of the shaft 5 extend outwards and threads are provided at both ends of the shaft 5. The shaft 5 penetrates the sleeve 4 and is connected to the fastening nut 7 by threads. Figure 8 shown.
[0046] Specifically, threads are provided at both ends of the rotating shaft 5 for connecting the fastening nut 7. By tightening the fastening nut 7, the stability of the handle 1 and the front fork 2 in use can be enhanced after the groove 301 and the tooth block 401 are engaged, thereby ensuring the use effect of the dust remover.
[0047] Based on the above-mentioned embodiment 1 and embodiment 2, in order to further improve the use effect, the end of the handle 1 away from the front fork 2 is connected to at least one connecting rod 8. Figure 8As shown, one end of the handle 1 is connected to a connecting rod 8, and the end of the connecting rod 8 is further connected to a tail cone. In this embodiment, the connecting rod 8 and the handle 1, the connecting rod 8 and the tail cone, and the connecting rod 8 are all connected by threads. The tail cone is used to decorate the connecting rod 8 and protect the threaded part of the connecting rod 8 from damage.
[0048] The handle 1 and the front fork 2 in this solution can hover at one or more angles of 90°, 120°, 160° and 180°, and the front fork 2 and the handle 1 can be continuously switched between the above angles through the hinged connection between the shaft seat 6 and the shaft sleeve 4 of the arc plate 3.
[0049] In addition, in order to prevent the dusting cloth from slipping, anti-slip blocks 201 are provided on the flanges on both sides of the front fork 2. Anti-slip blocks 201 are also provided on the front fork 2 of the dust duster to improve the use effect.
[0050] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
