Description

Technical Field

[0001] The utility model belongs to the field of bathing equipment such as outdoor small swimming pools, household intelligent constant temperature finished swimming pools, and in particular relates to a novel three-level lifting column and a swimming pool cover. Background Art

[0002] With the rapid development of society and the improvement of people's living standards, many villas, tourist hotels, resorts, high-end homestays or private venues have set up outdoor constant temperature swimming pools to meet people's swimming needs. However, since it is set up outdoors and the water in the swimming pool is generally not changed in a short period of time, in order to protect the swimming pool water from pollution and achieve energy saving and heat preservation, a cover is usually required. Many existing covers are realized by two-section lifting rods. Some can achieve tight coverage between the cover and the end face of the swimming pool when descending, but when the cover rises to the highest position, the distance between the cover and the end face of the swimming pool is relatively short, and swimmers need to bend down to enter the swimming pool, which is inconvenient; some covers can rise to a relatively high position, but when the cover falls to the lowest position, the cover plate cannot be in close contact with the end face of the swimming pool, so that there is still a certain distance between the cover and the swimming pool, and dustproof and heat preservation cannot be achieved. In order to overcome this defect, there is now a three-stage lifting column controlling the lifting structure of the cover. For example, application No. 202020824936.7 discloses an automatic lifting device for the insulation cover of a spa massage pool with a double-speed chain. However, this type of lifting column is directly installed on the swimming pool, which increases the load-bearing capacity of the swimming pool; at the same time, the lifting synchronization chain is located on the outside of the lifting column, so there are certain safety hazards in the use of the lifting synchronization chain, and the chain is in an exposed state and the swimming pool is in a high-humidity environment. The chain is easily affected by moisture and rusts, which affects the overall service life. Utility Model Content

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] Reference Figure 1 to Figure 6 A novel three-stage lifting column comprises a base 10, a support column 1, a lifting rod 3, a first-stage lifting column 4, a second-stage lifting column 5, a third-stage lifting column 6, a lifting device 7, a transmission chain 8, a first mounting plate 2 and a second mounting plate 9. The bottom end of the support column 1 is fixed on the base 10, the bottom end of the first-stage lifting column 4 is fixed on the base 10, the lifting rod 3 is connected to the lifting device 7, the lifting rod 3 is located above the base 10, one end of the transmission chain 8 is fixed on the support column 1, and the other end is fixed on the support column 1 after passing through the top end of the lifting rod 3, the second mounting plate 9 and the first mounting plate 2 in sequence, the second mounting plate 9 is fixed on the transmission chain 8 and is located above the first mounting plate 2, the second-stage lifting column 5 is fixed on the first mounting plate 2, the third-stage lifting column 6 is fixed on the second mounting plate 9, the bottom end of the second-stage lifting column 5 is sleeved in the first-stage lifting column 4, and the bottom end of the third-stage lifting column 6 is sleeved in the second-stage lifting column 5.

[0025] During the installation process, the support column 1 is welded and fixed on the base 10. After the transmission chain 8 is installed, the first-level lifting column 4 is sleeved on the outside of the support column 1, and the bottom end of the first-level lifting column 4 is fixed to the base 10 by screw locking; then the second-level lifting column 5 is installed, and the bottom end of the second-level lifting column 5 is fixed to the first mounting plate 2 by screw tightening, and can extend into the first-level lifting column 4; then the third-level lifting column 6 is installed, and the bottom end of the third-level lifting column 6 is fixed to the second mounting plate 9 by screw tightening. Among them, the base 10 can be directly fixed to the ground by bolts without being fixed to the swimming pool.

[0026] Since both ends of the transmission chain 8 are fixed on the support column 1, when the lifting rod 3 moves downward under the driving of the lifting device 7, the distance between the top of the lifting rod 3 and the top of the support column 1 is reduced, so that the transmission chain 8 between the two is shortened, and the other side of the chain after winding is correspondingly extended. At this time, the transmission chain 8 on the other side drives the second mounting plate 9 fixed thereto downward, and the second mounting plate 9 drives the third-level lifting column 6 downward together, and the first mounting plate 2 below also gradually descends, driving the second-level lifting column 5 downward, thereby achieving the second-level lifting column 5 and the third-level lifting column 6 are both downward, completing the downward shortening process. Conversely, when the lifting rod 3 moves upward under the driving action of the lifting device 7, the distance between the top of the lifting rod 3 and the top of the support column 1 increases, and the transmission chain 8 pulls the second mounting plate 9 upward. As the transmission chain 8 is pulled, the first mounting plate 2 is also pulled upward, achieving the upward extension of the second-level lifting column 5 and the third-level lifting column 6, greatly increasing the lifting height of the entire lifting column, and the lifting height can reach more than two meters.

[0027] In actual use, in order to reduce the friction between the lifting columns and reduce the wear on the first-level lifting column 4, the second-level lifting column 5 and the third-level lifting column 6, plastic gaskets 11 are installed on the outer side of the top of the first-level lifting column 4, the inner side of the bottom of the second-level lifting column 5, the outer side of the top, and the inner side of the bottom of the third-level lifting column 6 to avoid direct contact wear of the lifting columns.

[0028] The lifting device 7 includes a lifting motor 71 and a lifting screw 72. The lifting motor 71 is fixed on the base 10. The lifting screw 72 is connected to the output shaft of the lifting motor 71. The lifting rod 3 is threadedly connected to the lifting screw 72. The lifting screw 72 is located on one side of the support column 1. Therefore, the lifting motor 71 can drive the lifting screw 72 to rotate.

[0029] In order to facilitate the threaded connection between the lifting rod 3 and the lifting screw 72, a connecting nut 70 is fixed inside the lifting rod 3, one end of the connecting nut 70 is inserted into the lifting rod 3, and the bottom end is fixed to the bottom end of the lifting rod 3 by a screw. The connecting nut 70 is sleeved outside the lifting screw 72, and the two are matched by threads. Therefore, when the lifting motor 71 drives the lifting screw 72 to rotate, the lifting rod 3 can be lifted relative to the lifting screw 72.

[0030] A chain fixing member 20 is fixed to the top of the support column 1, and both ends of the conveying chain 8 are fixed to the chain fixing member 20. The chain fixing member 20 is fixed to the top of the support column 1 by screw locking. A corresponding U-shaped groove is provided on the chain fixing member 20, and the corresponding end of the conveying chain 8 extends into the corresponding U-shaped groove, and then the conveying chain is fixed by a pin. Therefore, by providing the chain fixing member 20, the installation of the conveying chain 8 can be facilitated.

[0031] The three-stage lifting column of the utility model further includes a guide sleeve 30, which is fixed to the chain fixing member 20 by screws, and the lifting rod 3 is sleeved in the guide sleeve 30, and there are two transmission chains 8. The guide sleeve 30 can guide the lifting of the lifting rod 3 and prevent the lifting rod 3 from shaking; the two transmission chains 8 can improve the load-bearing capacity and load-bearing strength, and ensure the stability of the lifting of the second-stage lifting column and the third-stage lifting column.

[0032] The three-stage lifting column of the utility model further comprises a top cover 40, a first sprocket 50 and a second sprocket 60. The top cover 40 is fixed to the top end of the lifting rod 3, the first sprocket 50 is mounted on the top cover 40, the second sprocket 60 is mounted on the first mounting plate 2, the other end of the transmission chain 8 passes through the first sprocket 50 and the second sprocket 60 in sequence and is then fixed to the support column 1, and the second mounting plate 9 is located between the first sprocket 50 and the second sprocket 60. Among them, a mounting hole is opened on the top cover 40, and the top end of the lifting rod 3 is inserted into the mounting hole to achieve relative fixation with the top cover 40.

[0033] By providing the first sprocket 50 and the second sprocket 60, the direction change of the conveying chain 8 is facilitated, the smooth transmission of the conveying chain 8 is facilitated, and the upward and downward movement of the corresponding lifting column is facilitated, thereby meeting the use requirements.

[0034] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the utility model also discloses a swimming pool cover, including the above-mentioned novel three-stage lifting column, and also including a cover plate 80. There are four novel three-stage lifting columns, and the top of each third-stage lifting column 6 is connected to the cover plate 80. In the actual assembly process, a connecting sleeve is fixed to the top of each third-stage lifting column 6 by screws, and the connecting sleeve is connected to the side of the cover plate 80 by screws, which is convenient for installation.

[0035] The swimming pool cover also includes a driving assembly 90. Two new three-stage lifting columns are installed on both long sides of the cover plate 80. The new three-stage lifting columns on the same side share a lifting motor 71. The lifting screw 72 is connected to the lifting motor 71 through the driving assembly. The two driving assemblies 90 on the same side are connected by a connecting rod 100. One end of the connecting rod 100 passes through the corresponding driving assembly 90 and then extends out. Among them, the driving assembly 90 is an existing common gear box transmission structure, and the gear box is a gear box with two-directional output shafts in the prior art. Specifically, when the lifting motor 71 is working, the output shaft of the lifting motor 71 is connected to the input end of one of the driving assemblies 90. Through the gears in the gear box, one of them is converted into a vertical output to drive the rotation of the lifting screw 72, and the other direction drives the connecting rod 100 to rotate. The connecting rod 100 drives the other driving assembly 90 on the same side to work, thereby driving the rotation of the lifting screw 72 on the same side, thereby realizing the synchronous extension and retraction of the lifting column on the same side.

[0036] Since the connecting rod 100 extends after passing through the corresponding driving assembly 90, that is, when in use, the connecting rod 100 on the side of the driving assembly 90 that is not directly connected to the lifting motor 71 extends, therefore, when the power is off or the lifting motor 71 cannot work normally, the operator can act on the extended connecting rod 100 to manually drive the connecting rod 100 to rotate, thereby driving the driving assembly to work, and realizing the manual control of the lifting column. In order to improve the integrity, an outer cover is provided on the base 10 to cover the extended part of the connecting rod 100, and when necessary, the outer cover can be opened for easy operation.

[0037] The bottom end surface of the cover plate 80 may be bonded and fixed with a sealing ring 81. The sealing ring 81 corresponds to the upper edge of the swimming pool, so when the cover plate 80 is driven by the lifting column to cover the swimming pool, the sealing ring 81 is pressed against the upper end surface of the swimming pool, which improves the tightness of the cover plate 80 and plays a good dustproof role.

[0038] The cover plate 80 includes a panel 801, a bottom plate 802 and a heat preservation layer, wherein the panel 801 and the bottom plate 802 are respectively covered on the upper and lower sides of the heat preservation layer, and the sealing ring 81 is located below the bottom plate 802. The heat preservation layer may be a foam layer, which may play a certain role in heat preservation and heat insulation. Therefore, through the covering effect of the cover plate 80, the heat loss rate in the swimming pool may be reduced, and a certain heat preservation effect may be played.

[0039] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
