Description
Technical Field
[0001] The utility model relates to the technical field of shower rooms, in particular to a lifting and rotating screen device. Background Art
[0002] Screens are a common piece of furniture used to block sight and divide space, but they take up a large space when stored and are not suitable for small spaces. According to the Chinese patent document with application number 201220510661.5 and the name of the document, “A liftable bathtub screen”, the rotating column and the column connecting the main body of the screen are connected by two upper and lower connecting pieces consisting of two round tubes. The two round tubes are respectively mounted on the rotating column and the column to connect the two. The connecting piece at the lower end is connected to the hydraulic rod installed in the column. In this way, when not in use, the screen can be lifted up to avoid the faucet on the wall, so that the screen can be completely stored against the wall. However, the following technical problems still exist in the use of this technology:
[0003] First, in order to allow the connecting piece to slide up and down, a sliding notch must be provided on the column in its vertical direction; at the same time, in order to allow the connecting piece to slide up and down smoothly in the column, a certain sliding space must be reserved in the column; these factors lead to poor connection stability between the connecting piece and the column, and no limiting mechanism is provided in the above technology, which causes the screen to easily shake back and forth and left and right during the lifting process, which is not only difficult to operate, but also causes harsh noise due to the friction between the connecting piece and the column, resulting in poor customer experience; and due to the shaking of the connecting piece, the load on the hydraulic rod is unevenly distributed, which can easily cause bending and wear of the hydraulic rod plunger, seriously affecting the normal use of the hydraulic rod and seriously shortening the service life of the hydraulic rod.
[0004] Second, from the text of the technical solution and the appendix to the specification Figure 2 As shown in , in this technical solution, the hydraulic rod is arranged at the bottom end of the column, that is, it is installed on the ground. In this way, moisture and dust on the ground can easily corrode the hydraulic rod during use, especially when the screen body is lifted, the hydraulic rod is directly exposed to the external environment. After long-term use, the metal parts of the hydraulic rod are prone to rust, and moisture and dust will also penetrate into the inside of the hydraulic rod, thereby causing various phenomena such as blockage of the hydraulic rod, wear of the seals, deterioration of the hydraulic oil, etc., which makes the hydraulic rod malfunction frequently and shortens its service life. Utility Model Content
[0005] The purpose of the utility model is to solve the above-mentioned problems and shortcomings, and to provide a hydraulic lifting and rotating silent screen device. By arranging connecting columns and lifting columns arranged along the vertical direction of the fixed columns, and assembling the connecting columns and the lifting columns in a nested manner, the stability between the lifting columns and the fixed columns can be greatly improved. When the screen body moves up and down, it is not easy to shake, thereby improving the flexibility of operation and avoiding noise. At the same time, the load applied to the hydraulic lifting assist device is evenly distributed, which is conducive to improving the stability of its use, thereby extending its service life. In addition, the hydraulic lifting assist device is concealedly installed between the connecting column and the lifting column, which can avoid erosion by erosive substances such as moisture and dust, further ensuring its working stability and extending its service life.
[0006] The technical solution of the utility model is achieved in this way:
[0007] A hydraulic lifting and rotating silent screen device comprises a screen body, a fixed column, and a hydraulic lifting assisting device, and is characterized in that: it also comprises a connecting column and a lifting column arranged along the vertical direction of the fixed column, the connecting column and the fixed column are nested and assembled, the lifting column and the connecting column are embedded and can move up and down along the vertical direction of the connecting column, the screen body and the lifting column are mutually hingedly connected at the top and bottom ends; the hydraulic lifting assisting device is concealedly installed between the connecting column and the lifting column to assist in pushing the screen body and the lifting column to move upward.
[0008] Furthermore, the connecting column is provided with a receiving groove, and sliding grooves are respectively provided on the groove walls on both sides of the receiving groove; the lifting column is provided with an embedding convex strip, and guide wheels are respectively provided on both sides of the embedding convex strip; the lifting column is embedded in the receiving groove through the embedding convex strip, and the guide wheel is embedded in the sliding groove, so that the lifting column and the connecting column are embedded together.
[0009] Furthermore, the hydraulic lifting assist device includes a hydraulic rod body, a guide rail, a limit block, a sliding top block, and a fixed base. The fixed base and the guide rail are respectively installed in the connecting column, the limit block is installed on the embedded convex strip corresponding to the guide rail, the bottom end of the hydraulic rod body is connected to the fixed base, the sliding top block is installed at the top end of the hydraulic rod body, and the sliding top block is in sliding contact with the guide rail, and the sliding top block and the limit block are abutted against each other.
[0010] Furthermore, the connecting column is provided with a accommodating cavity for storing the hydraulic lifting assist device and communicating with the accommodating groove. The cavity walls on both sides of the accommodating cavity are also provided with limiting baffles, which separate the accommodating cavity into a first limiting groove. The fixed base and the guide rail are respectively provided with first limiting convex edges which are nested with the first limiting groove.
[0011] Furthermore, the side surface of the guide rail is also provided with a guide convex strip, and the sliding top block is correspondingly provided with a guide groove embedded in the guide convex strip.
[0012] Furthermore, the limit block is composed of an installation bottom and a limit portion, and second limit convex edges are respectively provided on both sides of the installation bottom, and a second limit groove with a folded edge is also provided on the side of the embedded convex strip. The installation bottom is embedded in the second limit groove, and the limit block is installed on the side of the embedded convex strip by utilizing the mutual embedding and limiting of the second limit convex edge and the second limit groove.
[0013] Furthermore, the top surface and the side surface of the sliding top block are respectively provided with a top contact portion and a concave position abutting against the limit block.
[0014] Furthermore, the guide wheel is installed on the embedding convex strip through a wheel axle provided on the embedding convex strip, and the outer end of the wheel axle is in an arc shape.
[0015] Furthermore, the installation height H of the hydraulic lifting assist device is greater than or equal to the lifting height L of the lifting column.
[0016] First, since connecting columns and lifting columns are arranged along the vertical direction of the fixed column, and the connecting columns and the lifting columns are nested and assembled, the volumes of the connecting columns and the lifting columns are larger, so that their mechanical strength is also larger, and the contact area between the two is increased, so that the lifting column can be stably limited in the connecting column, so that when the lifting column drives the screen body to move up and down, it is not easy to shake, so that the hydraulic lifting assist device can smoothly push the screen body and the lifting column to move upward, which is not only easy to operate, but also can avoid the generation of harsh noise, thereby greatly improving the customer's experience; at the same time, the load applied to the hydraulic lifting assist device is evenly distributed, and it is not easy to cause the plunger of the hydraulic rod to bend or wear, thereby greatly improving the working stability of the hydraulic lifting assist device and helping to extend its service life.
[0017] Secondly, the hydraulic lifting assist device is concealedly installed between the connecting column and the lifting column, so that when in use, it can effectively avoid erosion by external harmful substances such as moisture, dust, etc., and can maintain excellent working performance even after long-term use, thereby greatly extending the service life of the utility model.
[0018] In addition, the assembly of the hydraulic lifting assist device with the connecting column and the lifting column can be completed in advance in the factory. This can not only reduce the workload of on-site installation and speed up construction, but also prevent the dust generated during on-site construction from corroding the hydraulic lifting assist device, thereby helping to extend its service life.

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is clearly and completely described below in conjunction with the accompanying drawings of the present invention.
[0028] like Figures 1 to 6As shown, the utility model describes a hydraulic lifting and rotating silent screen device, comprising a screen body 1, a fixed column 2, and a hydraulic lifting assisting device 3. In order to achieve the purpose proposed by the utility model, it also includes a connecting column 4 and a lifting column 5 arranged along the vertical direction of the fixed column 2. The connecting column 4 and the fixed column 2 are nested and assembled, and the lifting column 5 is embedded in the connecting column 4 and can move up and down along the vertical direction of the connecting column 4. The screen body 1 and the lifting column 5 are mutually hingedly connected at the top and bottom ends; the hydraulic lifting assisting device 3 is hiddenly installed between the connecting column 4 and the lifting column 5 to assist in pushing the screen body 1 and the lifting column 5 to move upward. In this way, the hydraulic lifting assist device, the connecting column and the lifting column can be pre-assembled in the factory, thereby reducing the number of parts and avoiding the loss of parts during transportation and on-site installation; at the same time, due to the reduction in the workload on the construction site, the installation rate can be greatly improved, and the dust generated on the construction site can be effectively prevented from eroding the hydraulic lifting assist device, which helps it maintain stable working performance; during on-site installation, the top and bottom ends of the screen body 1 are respectively hingedly connected to the lifting column 5, and then embedded into the fixing column 2 that has been fixed on the wall through the connecting column 4, thereby realizing the installation of the entire screen device.
[0029] like Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the connecting column 4 is provided with a receiving groove 41, and sliding grooves 411 are respectively provided on the groove walls on both sides of the receiving groove 41, and the lifting column 5 is provided with an embedded convex strip 51, and guide wheels 53 are respectively provided on both sides of the embedded convex strip 51; the lifting column 5 is embedded with the receiving groove 41 by embedding the embedded convex strip 51, and the guide wheel 53 is embedded in the sliding groove 411, so that the lifting column 5 and the connecting column 4 are embedded together. In this way, the horizontal and vertical directions of the embedded convex strip 51 are both limited in the receiving groove 41, so that the lifting column 5 can maintain better stability and is not easy to shake when it moves up and down in the connecting column 4.
[0030] like Figure 2 , Figure 5 , Figure 6 , Figure 7As shown, the hydraulic lifting assist device 3 includes a hydraulic rod body 31, a guide rail 32, a limit block 33, a sliding top block 34, and a fixed base 35. The fixed base 35 and the guide rail 32 are respectively installed in the connecting column 4, and the limit block 33 is installed on the embedded convex strip 51 corresponding to the guide rail 32. The bottom end of the hydraulic rod body 31 is connected to the fixed base 35, and the sliding top block 34 is installed at the top end of the hydraulic rod body 31, and the sliding top block 34 is in sliding contact with the guide rail 32, and the sliding top block 34 is against the limit block 33. In this way, the upper and lower ends of the hydraulic rod body 31 are stably limited in the connecting column 4, so as to ensure that it can stably drive the lifting column 5 and the screen body 1 to move up and down on the connecting column 4.
[0031] like Figures 2 to 6 As shown, the connecting column 4 is provided with a receiving cavity 42 for hiding the hydraulic lifting assist device 3 and intersecting with the receiving groove 41, and the cavity walls on both sides of the receiving cavity 42 are also provided with limiting baffles 421, and the limiting baffles 421 separate the receiving cavity 42 to form a first limiting groove 422, and the fixed base 35 and the guide rail 32 are respectively provided with first limiting convex edges 322 nested with the first limiting groove 422. During installation, the fixed base 35 and the guide rail 32 are respectively embedded in the first limiting groove 422, and then positioned by screws. Due to the limiting effect of the limiting baffle 421 and the first limiting convex edge 322, the connection area between the fixed base 35, the guide rail 32 and the connecting column 4 is large, thereby greatly enhancing the stability and force strength of the fixed base 35 and the guide rail 32 when installed in the connecting column 4, and it is not easy to loosen during use, thereby ensuring the working stability of the utility model.
[0032] like Figure 7 As shown, the side of the guide rail 32 is further provided with a guide convex strip 321, and the sliding top block 34 is correspondingly provided with a guide groove 341 which is embedded in the guide convex strip 321. In this way, a limiting mechanism is formed between the guide convex strip 321 and the guide groove 341, so that when the sliding top block 34 slides up and down along the guide rail 32, it slides more stably and is less likely to shake or shift.
[0033] like Figure 5 , Figure 7As shown, the limit block 33 is composed of a mounting bottom 330 and a limit portion 333, and the two sides of the mounting bottom 330 are respectively provided with a second limit convex edge 331, and the side of the embedded convex strip 51 is also provided with a second limit groove 512 with a folded edge 511, and the mounting bottom 330 is embedded in the second limit groove 512, and the limit block 33 is installed on the side of the embedded convex strip 51 by using the second limit convex edge 331 and the second limit groove 512 to realize the installation of the limit block 33 on the side of the embedded convex strip 51, and then the limit block 33 is positioned on the embedded convex strip 51 by screws. In this way, the contact area between the limit block 33 and the embedded convex strip 51 can be increased, thereby strengthening the connection strength between the two, and the limit block 33 is not easy to loosen during use, thereby further strengthening the stability of the operation of the device of the utility model.
[0034] like Figure 7 As shown, the top surface and side surface of the sliding top block 34 are respectively provided with a top contact portion 342 and a concave position 343 that abut against the limit block 33. In this way, the sliding top block 34 and the limit block 33 are more closely abutted against each other, which not only better positions the sliding top block 34, but also enables the sliding top block 34 to more stably push the limit block 33 upward, thereby driving the lifting column 5 and the screen body 1 to move upward.
[0035] like Figure 5 As shown, the guide wheel 53 is installed on the embedded convex strip 51 through the wheel shaft 54 provided on the embedded convex strip 51, and the outer end of the wheel shaft 54 is in an arc shape. In this way, a rolling contact with extremely small friction resistance is formed between the guide wheel 52 and the two side walls of the sliding groove 411, and a point contact is formed between the outer end of the wheel shaft 54 and the bottom of the sliding groove 411. This arrangement can reduce the gap between the embedded convex strip 51 and the accommodating groove 41 to prevent the embedded convex strip 51 from shaking, and can also avoid a large friction force between the two, so that the lifting column 5 can drive the screen body 1 to move up and down stably and smoothly.
[0036] like Figure 8 As shown, the installation height H of the hydraulic lifting assist device 3 is greater than or equal to the lifting height L of the lifting column 5, so that the hydraulic lifting assist device 3 is spaced a certain height from the ground, thereby effectively avoiding the erosion of ground water and dust; and even after the screen body 1 is lifted, the hydraulic lifting assist device 3 can be well hidden to avoid being eroded by water and dust, so as to maintain the best working performance and extend the service life.
[0037] like Figure 3 , Figure 4As shown, the side of the fixing column 2 is also provided with a screw installation hidden groove 21, and the screw installation hidden groove 21 is also covered with a cover plate 22. In this way, the fixing column 2 can be fixedly connected to the connecting column 4 by screws, and then the screws are covered by the shielding cover 21, thereby maintaining a flat and beautiful appearance.
[0038] like Figure 1 , Figure 2 As shown, in order to maintain the overall appearance of the hydraulic lifting assist device 3 and prevent moisture, dust and the like from corroding the hydraulic lifting assist device 3, the first cover 20, the second cover 40 and the third cover 50 are respectively embedded at the upper and lower ends of the fixed column 2, the connecting column 4 and the lifting column 5, and the second cover 40 and the third cover 50 are respectively provided with screw through holes 401, and the connecting column 4 and the lifting column 5 are also respectively provided with screw hole portions 402, so that the screws pass through the screw through holes 401 and are then screwed on the screw hole portions 402, so that the second cover 40 and the third cover 50 can be respectively firmly installed on the connecting column 4 and the lifting column 5. In addition, the screw hole portions 402 are arranged along the vertical direction of the connecting column 4 and the lifting column 5, which, on the one hand, provide bolt installation positions and connect the second cover 40 and the third cover 50, and at the same time, they can also serve as reinforcing ribs to enhance the mechanical strength of the connecting column 4 and the lifting column 5.
[0039] like Figure 3 , Figure 5 As shown, the lifting column 5 is also provided with a hinged portion 52 hingedly connected to the screen body 1, and the hinged portion 52 is provided with an arc-shaped groove 521. At the same time, the upper and lower ends of the screen body 1 are respectively provided with a rotating shaft core 11, and the bottom surface of the third cover 50 is provided with a fitting hole 501; in this way, the side of the screen body 1 is embedded in the arc-shaped groove 521, the rotating shaft core 11 is fitted into the fitting hole 501, and the third cover 50 is fixed on the lifting column 5, so as to realize the hinged connection between the screen body 1 and the lifting column 5. When in use, the screen body 1 rotates inside the arc-shaped groove 521 through the rotating shaft core 11.
[0040] When the utility model is installed in a shower room, the arc groove 521 can also prevent water from splashing outside the screen, and has a good waterproof effect. In addition, as shown in the figure, a water-retaining rubber strip 12 is also provided at the bottom of the screen body to prevent water from diverting the shower room and dirtying the floor of the dry area.
[0041] The fixed column 2, the connecting column 4 and the lifting column 5 in the utility model are all made of aluminum profile materials which are easy to process, and the hydraulic lifting assist device 3 can purchase an existing hydraulic device. Therefore, the utility model has low difficulty in processing and manufacturing, easy cost control, easy operation, long service life, and good market competitiveness.
