Description

Technical Field

[0001] The invention relates to the technical field of suction cup handrails, and in particular to an assembled suction cup handrail suitable for ships. Background Art

[0002] Ships often go up and down when sailing on the water. At this time, the crew members on the ship often need to hold on to fixed objects around them for stability. However, when the cabin space is relatively empty, they cannot find effective objects to stabilize their bodies. For this reason, the prior art has proposed a variety of temporary handrails for ships, such as the ship handrail with publication number CN204956852U and a detachable ship handrail with publication number CN221214460U that can reduce the weight of the ship. However, the handrails of the above-mentioned structure are usually installed in a relatively fixed position and cannot be used at any time. Further, the suction cup handrail technology has appeared in the prior art, which can be adsorbed on various smooth walls such as glass, tiles, etc. through suction cups to play a temporary stabilizing and protective role. The suction cup handrail technology uses the principle of vacuuming to fix the suction cup at the end of the handrail to the wall. It is not only firmly installed, but also solves the problem of difficulty in installing and removing the handrail. It is also very suitable for use as a temporary safety device on ships.

[0003] However, the suction cup handrails in the prior art still have their limitations, as follows: 1. The handrail rod and the suction cup are mostly made of one-piece injection molding, and their length and structure are fixed once they are manufactured; 2. Handrails with special needs, such as handrails with certain angle requirements, need to be specially customized, and the angle cannot be adjusted later. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention proposes an assembled suction cup handrail which has a simple structure, is easy to install and can meet the requirements of different lengths and angles of use.

[0005] The present invention is achieved through the following technical solutions: An assembled suction cup handrail suitable for ships includes a handrail rod and a suction cup assembly. Both ends of the handrail rod are detachably connected to the suction cup assembly. The handrail rod is in a "∏" shape as a whole. Both ends of the handrail rod are provided with plug rods. The suction cup assembly is provided with plug holes corresponding to the plug rods. When assembling the assembled suction cup handrail, the plug rods at both ends of the handrail rod are inserted into the plug holes and fixed. The detachable handrail rod and suction cup assembly are easy to install and can well meet different usage scenarios. When the space is relatively narrow, a short handrail rod and suction cup assembly can be used for assembly. When the space is larger, a long handrail rod and suction cup assembly can be used for assembly and use.

[0006] As a further improvement of the present invention, a convex column is provided at the bottom of the socket, and a groove corresponding to the shape of the convex column is provided on the end face of the plug rod, and when the assembled suction cup handrail is assembled, the convex column is embedded in the groove. The use of the convex column and the groove can better complete the positioning and fixing of the plug rod and the socket.

[0007] As a further improvement of the present invention, a mounting hole is provided on the insertion rod, and a through hole corresponding to the mounting hole is provided in the insertion hole. When the assembled suction cup handrail is assembled, the connection and fixation between the insertion rod and the insertion hole are completed by passing a bolt through the mounting hole and the through hole and then fixing it with a nut.

[0008] As a further improvement of the present invention, the cross-sectional shape of the protruding column is a centrally symmetrical shape.

[0009] As a further improvement of the present invention, the cross-section of the boss is octagonal. If the boss is octagonal, the corresponding groove is also an octagonal groove, which not only facilitates the positioning of the boss and the groove during assembly, but also plays a fixing role.

[0010] As a further improvement of the present invention, the suction cup assembly includes at least two sockets, each of which is connected to the insertion rod of a different handrail rod. After the suction cup assembly is provided with at least two sockets, the same suction cup assembly can be assembled with at least two handrail rods at the same time. After the cross section of the protruding column is set to a centrally symmetrical shape such as an octagon, different angles can be formed between the handrail rods assembled on the same suction cup assembly. The assembly combination of multiple handrail rods and multiple suction cup assemblies can form handrails of various lengths and extension forms.

[0011] As a further improvement of the present invention, the suction cup assembly includes a shell, a snap-on switch, a pull rod, a pull rod disc, and a suction cup glue, wherein the jack is arranged on the shell; an eccentric hole is arranged on the snap-on switch, and the snap-on switch includes a first contact surface and a second contact surface, wherein the first contact surface is perpendicular to the second contact surface, and a transition fillet is arranged between the two. By toggling the snap-on switch, the snap-on switch can switch from contacting with the shell through the first contact surface to contacting with the shell through the second contact surface, and at this time, the position of the eccentric hole relative to the shell will change; one end of the pull rod passes through the shell and the snap-on switch. The eccentric hole of the closing switch is connected, and the other end is fixedly connected to the pull rod disc; one side of the suction cup glue is smooth, and the other side wraps the pull rod disc; the outer shell is hemispherical with one side open, and the suction cup glue covers the opening of the outer shell. When the assembled suction cup handrail is in use, the smooth side of the suction cup glue is pressed against the wall, and the closing switch is pulled to drive the pull rod to move toward the outer shell, and the pull rod drives the pull rod disc to pull the suction cup glue in a direction vertically and away from the wall, forming a vacuum between the suction cup glue and the wall to realize the adsorption of the suction cup assembly to the wall.

[0012] As a further improvement of the present invention, a pressure identification component is also provided on the shell, and the pressure identification component includes a spring, a color ring, an identification column, a color display window, a mounting pin and a mounting pin hole; a countersunk hole is provided on the shell, and the spring is arranged in the countersunk hole, one end of the spring is fixedly connected to the shell, and the other end is fixedly connected to the identification column, and the color ring is sleeved on the end of the identification column connected to the spring; a long hole extending along the identification column is provided on the identification column, the mounting pin hole passes through the shell and is connected to the countersunk hole and the long hole, and the mounting pin passes through the mounting pin hole and the long hole; the color display window is arranged on the shell and is connected to the countersunk hole; when the assembled suction cup handrail is not adsorbed to the wall, the spring is in a partially compressed state and pushes the identification column out of the countersunk hole, and the mounting pin passing through the long hole prevents the identification column from being completely pushed out of the countersunk hole by the spring and keeps the identification column partially extending out of the shell; When the snap-on switch is pulled to allow the assembled suction cup handrail to be adsorbed onto the wall, the identification column is squeezed into the countersunk hole by the wall, and the color ring is driven by the identification column to move to the color display window for display.

[0013] As a further improvement of the present invention, at least two color rings are sequentially mounted on the identification column, and each color ring has a different color. The color rings of different colors can represent the adsorption force between the suction cup assembly and the wall surface at this time, and the user can judge whether the suction cup assembly is firmly adsorbed on the wall surface by observing the color displayed in the color display window.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the assembled suction cup armrest has a simple structure and is easy to install, and the length and angle can be adjusted according to the different needs of the user and scenes.

DETAILED DESCRIPTION

[0017] The following will clearly and completely describe the technical solutions of various embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings. Example

[0019] An assembled suction cup handrail suitable for ships comprises a handrail rod 1 and a suction cup assembly 2. Both ends of the handrail rod 1 are detachably connected to the suction cup assembly 2. The handrail rod 1 is in a "∏" shape as a whole. Both ends of the handrail rod 1 are provided with plug rods 3. The suction cup assembly 2 is provided with sockets 4 corresponding to the plug rods 3. When assembling the assembled suction cup handrail, the plug rods 3 at both ends of the handrail rod 1 are inserted into the sockets 4 and fixed. The handrail rod 1 and the suction cup assembly 2 with detachable design are easy to install and can well meet different usage scenarios. When the space is relatively narrow, a short handrail rod and the suction cup assembly 2 can be used for assembly. When the space is larger, a long handrail rod and the suction cup assembly 2 can be used for assembly and use.

[0020] A boss 5 is provided at the bottom of the socket 4, and a groove 6 corresponding to the shape of the boss 5 is provided on the end face of the plug rod 3. When the assembled suction cup handrail is assembled, the boss 5 is embedded in the groove 6. The positioning and fixation of the plug rod 3 and the socket 4 are better achieved through the form of the boss 5 and the groove 6.

[0021] A mounting hole 7 is provided on the insertion rod 3, and a through hole 8 corresponding to the mounting hole 7 is provided in the insertion hole 4. When the assembled suction cup handrail is assembled, the connection and fixation of the insertion rod 3 and the insertion hole 4 are completed by passing the bolts through the mounting hole 7 and the through hole 8 and then fixing them with nuts.

[0022] In this embodiment, the cross-section of the boss 5 is octagonal. If the boss 5 is set to be octagonal, the corresponding groove 6 is also an octagonal groove, which not only facilitates the positioning of the boss 5 and the groove 6 during assembly, but also plays a fixing role.

[0023] In other embodiments, the cross section of the boss 5 may also be in other shapes such as a circle, a triangle, a square or other centrosymmetrical shapes.

[0024] The suction cup assembly 2 includes a housing 9, a snap-on switch 10, a pull rod 11, a pull rod disc 12, and a suction cup glue 13. The jack 4 is arranged on the housing 9. The snap-on switch 10 is provided with an eccentric hole 14. The snap-on switch 10 includes a first contact surface 15 and a second contact surface 16. The first contact surface 15 is perpendicular to the second contact surface 16, and a transition fillet 17 is provided between the first contact surface 15 and the second contact surface 16. By toggling the snap-on switch 10, the snap-on switch 10 can switch from contacting with the housing 9 through the first contact surface 15 to contacting with the second contact surface 16. At this time, the position of the eccentric hole 14 relative to the housing 9 will change. One end of the pull rod 11 passes through the housing 9 and snaps on the switch 10. The outer shell 9 is hemispherical with one side open, and the suction cup glue 13 covers the opening of the outer shell 9. When the assembled suction cup handrail is used, the smooth side of the suction cup glue 13 is pressed against the wall, and the snap-on switch 10 is pulled to drive the pull rod 11 to move toward the outer shell 9. The pull rod 11 drives the pull rod disc 12 to pull the suction cup glue 13 in a direction perpendicular to and away from the wall, forming a vacuum between the suction cup glue 13 and the wall to realize the adsorption of the suction cup assembly 2 on the wall.

[0025] In this embodiment, the housing 9 is further provided with a pressure identification assembly 18, which includes a spring 19, a color ring 20, an identification column 21, a color display window 22, a mounting pin 23 and a mounting pin hole 24. The housing 9 is provided with a countersunk hole 25, in which the spring 19 is arranged. One end of the spring 19 is fixedly connected to the housing 9, and the other end is fixedly connected to the identification column 21. The color ring 20 is sleeved on the end of the identification column 21 connected to the spring 19. The identification column 21 is provided with a long hole 26 extending along the identification column 21 , the mounting pin hole 24 penetrates the housing 9 and is connected with the counterbore 25 and the long hole 26 , and the mounting pin 23 passes through the mounting pin hole 24 and the long hole 26 .

[0026] The color development window 22 is disposed on the housing 9 and communicates with the counterbore 25 .

[0027] When the assembled suction cup handrail is not adsorbed to the wall, the spring 19 is in a partially compressed state and pushes the identification column 21 out of the countersunk hole 25. The mounting pin 23 passing through the long hole 26 prevents the identification column 21 from being completely pushed out of the countersunk hole 25 by the spring 19 and keeps the identification column 21 partially extending out of the housing 9.

[0028] When the snap-on switch 10 is pulled to make the assembled suction cup handrail adsorb to the wall, the identification column 21 is squeezed into the countersunk hole 25 by the wall, and the color ring 20 is driven by the identification column 21 to move to the color display window 22 for display.

[0029] The identification column 21 is covered with two color rings, red and green, in sequence. The color rings of different colors can indicate the adsorption force between the suction cup assembly 2 and the wall at this time. The user can judge whether the suction cup assembly 2 is firmly adsorbed on the wall by observing the color displayed in the color window 22. When the adsorption force of the suction cup assembly 2 is insufficient, the identification column 21 cannot be completely pushed into the countersunk hole 25, and the red color ring can be observed in the color window 22. When the suction cup assembly 2 is completely adsorbed on the wall, the green color ring can be observed in the color window 22. Example

[0030] In this embodiment, the structure of the handrail rod 1 is the same as that of the first embodiment. Two sockets 4 are provided on each suction cup assembly 2. The same suction cup assembly 2 can be connected to two handrail rods 1, thereby realizing a scenario in which a longer handrail assembly is formed by connecting multiple handrail rods 1. Fig.14 As shown, in this embodiment, there are three handrail rods 1 and four suction cup assemblies 2.

[0031] At the same time, the boss 5 of the suction cup assembly 2 in this embodiment is still octagonal. Through the cooperation of the octagonal boss 5 and the groove 6, the two handrails 1 connected to the same suction cup assembly 2 can produce different angle combinations, such as Fig.15 shown.

[0032] In this embodiment, the angle between the two handrail bars 1 connecting the unified suction cup assembly can be changed by 45°. In other embodiments, the boss 5 with different cross-sectional shapes can be designed according to the requirements of the combined angle of the two handrail bars 1. For example, the square boss 5 satisfies the requirement that the angle of the handrail bar 1 changes by 90°, and the hexagonal star-shaped boss 5 satisfies the requirement that the angle of the handrail bar 1 changes by 60°.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the technical solutions of the embodiments of the present invention.
