Description

Technical Field

[0001] This utility model belongs to the technical field of bathroom equipment, and specifically refers to a lifting rod structure and a shower. Background Technology

[0002] Rising shower heads, when used in showers, can accommodate users of different heights to meet varying water flow height requirements. Handheld shower heads typically adjust their height by sliding a shower head seat mounted on a rod; this adjustment is a single-stroke process, with the shower head seat's travel range extending between both ends of the rod. This results in a longer product length, significantly impacting installation space, packaging, and transportation. Furthermore, the excessive travel makes it difficult for shorter users to move the shower head seat to its highest position, leading to a poor user experience.

[0003] To address this issue, existing technologies include a showerhead (patent 201810011385.X) that discloses a shower unit where the handheld and overhead showerheads can be raised and lowered in tandem, but only synchronously, not independently. Furthermore, its structure is overly complex, with an excessively long lever within the overhead showerhead assembly, making it difficult for users to operate the buttons. The front-facing buttons are also prone to accidental activation, causing the overhead showerhead assembly to slip and potentially injure the user. Patent 202323232354.2 discloses a height-adjustable showerhead where the lever and fixed base are connected via… The damping balance component and friction are used to achieve hovering, but the structure is not stable enough and is prone to shaking, which can cause the rod to slip off. Patent 202420984260.6 discloses a double sliding lifting rod, which includes a base, a lifting body that slides with the base, and a slide block that slides with the lifting body. It also has a moving block for locking the base and the lifting body. The first button for user operation is connected to the moving block through a push block. The moving direction of the push block is perpendicular to the moving direction of the moving block, which is a 90° linkage structure. This results in a thicker overall structure, making it difficult to make it thinner. Utility Model Content

Detailed Implementation

[0036] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0037] refer to Figures 1 to 11 As shown, the first and second embodiments of this utility model are illustrated, both of which are lifting rod structures, including a wall base 1, a rod 2, a limiting member 3, an elastic member 4, and an operating member 5 for user operation; The wall mount 1 is pre-fixed to the mounting surface, which generally refers to the wall of the bathroom; The rod 2 slides in the vertical direction with the wall base 1 to achieve the lifting function; The limiting member 3 slides and engages with the rod 2 in the left and right directions to achieve locking in the up and down directions when it abuts against the wall seat 1; The elastic element 4 is installed on the rod 2 and acts on the limiting element 3 so that the limiting element 3 abuts against the wall base 1; The operating component 5 and the limiting component 3 are arranged in parallel directions of movement and are telescopically fitted on the side of the rod 2; the operating component 5 and the limiting component 3 are linked to enable the user to drive the limiting component 3 to separate from the wall base 1 through the operating component 5; among them, the preferred method is that the operating component 5 and the limiting component 3 are coaxially arranged, and "coaxial arrangement" means that the central axis of the operating component 5 and the central axis of the limiting component 3 are collinear.

[0038] Through the above scheme, the rod 2 and the wall base 1 of this utility model slide in the vertical direction, and the wall base 1 can be pre-fixed on the mounting surface (i.e., the wall surface), thereby realizing the lifting function of the rod 2 relative to the mounting surface. At the same time, the elastic element 4 drives the limiting element 3 to abut against the wall base 1 to realize the locking function, which can fix the rod 2 at a certain height. By setting the operating element 5 on the side of the rod 2 and coaxially arranged with the limiting element 3, the operating element 5 and the limiting element 3 can slide in the same direction and along the same straight line. There is no need to reserve more space for the sliding of the limiting element 3 and the operating element 5 in the front-back direction of the rod 2. Compared with the prior art, the thickness of the rod 2 can be designed to be thinner, achieving a smaller size and obvious cost advantages.

[0039] refer to Figures 1 to 9 The first embodiment of this utility model is shown. See also... Figures 1 to 6 The structural details of the first embodiment are shown: A linkage 6 is rotatably mounted within the aforementioned rod 2, located between the operating member 5 and the limiting member 3. Both sides of the linkage 6 are provided with swing arms 61. The limiting member 3 has a movable groove 31 on its side facing the linkage 6, and a protruding hook 32 is provided on the end wall of the movable groove 31. The end of one swing arm 61 of the linkage 6 is located within the movable groove 31 and movably abuts against the inner wall of the hook 32. The operating member 5 movably abuts against the end of the other swing arm 61 of the linkage 6. Thus, see... Figure 8 , Figure 9 The linkage 6 realizes lever transmission between the operating part 5 and the limiting part 3. When the user presses the operating part 5, the linkage 6 can be driven to swing. The swing arm 61 of the linkage 6 abuts against the inner wall of the hook part 32 to realize the sliding of the limiting part 3, thereby separating the limiting part 3 from the wall seat 1, unlocking the up and down sliding of the rod 2, and then the height of the rod 2 can be adjusted. In addition, the length of the swing arms 61 on both sides of the linkage 6 can be adjusted in the size design of the parts, that is, the lever arm size can be adjusted, so that the user can press the operating part 5 with less effort.

[0040] In the first embodiment, the rod 2 is further provided with a mounting base 7, which is detachably installed in the rod 2 by means of screw locking, snap-fit ​​connection, etc., and has a mounting groove 71. The rod 2 is provided with a first through hole 21 for the installation of the operating member 5. The two sides of the mounting groove 71 are respectively provided with opposing second through holes 72 and third through holes 73, and the first through hole 21, second through hole 72 and third through hole 73 are collinear. The limiting member 3 is telescopically fitted in the second through hole 72, and the operating member 5 is simultaneously telescopically fitted in the first through hole 21 and third through hole 73. The mounting groove 71 is provided with a rotating shaft 74 for the rotation of the linkage member 6.

[0041] Furthermore, the aforementioned operating component 5 includes a separate button 5a and a slider 5b; the button 5a simultaneously extends and retracts within the first through hole 21 and the third through hole 73; the slider 5b is positioned between the linkage 6 and the button 5a, with its inner end movably abutting against the end of the swing arm 61 of the linkage 6, and the outer end of the slider 5b is assembled with the button 5a by means of screw fastening, snap-fit ​​connection, etc.; the inner wall of the mounting groove 71 is provided with a guide groove 75 extending along the axial direction (i.e., the left-right direction) of the third through hole 73, and the inner end side of the slider 5b is provided with a guide protrusion 51 that slides between the two ends of the guide groove 75. Therefore, by separating the operating component 5 into a button 5a and a slider 5b, the two parts can be made of two different materials. The button 5a can be made of a soft, skin-friendly material to optimize the operating feel, while the slider 5b can be made of a high-strength material to improve its service life. Simultaneously, the cooperation between the guide protrusion 51 and the guide groove 75 restricts the sliding stroke of the operating component 5, preventing the entire operating component 5 from dislodging from the first through hole 21 / third through hole, and also avoiding excessive force on the linkage 6, which could break the swing arm 61. Specifically, two pairs of guide protrusions 51 and guide grooves 75 are symmetrically arranged vertically to prevent the operating component 5 from wobbling during sliding. The inner end of the slider 5b has an inclined surface 52 that mates with the end of the swing arm 61. When the slider 5b slides, the end of the swing arm 61 moves along the inclined surface 52 to achieve the rotation of the linkage 6. The outer end face of the button 5a has several anti-slip protrusions 53 to prevent slippage when the user presses it.

[0042] Meanwhile, a limiting cover 8 is also provided inside the aforementioned rod 2. The limiting cover 8 is detachably connected to the mounting base 7 by means of screw locking, snap-fit ​​connection, etc., and is used to axially limit the linkage 6 to prevent it from detaching from the rotating shaft 74. Specifically, the limiting cover 8 is provided with a shaft groove 81 for the rotating shaft 72 to be inserted, so as to prevent the rotating shaft 74 and the linkage 6 from bending or deforming when subjected to the thrust of the operating member 5.

[0043] Furthermore, the aforementioned elastic element 4 is a spring, and one is provided at each of the upper and lower ends of the limiting element 3; the upper and lower ends of the side of the limiting element 3 facing the operating element 5 are provided with spring grooves 33; one end of the elastic element 4 is disposed in the spring groove 33, and the other end abuts against the inner wall of the mounting groove 71. Thus, when the elastic element 4 is compressed, it can provide elastic force to make the limiting element 3 tend to move away from the operating element 5.

[0044] In the first embodiment, two linkage components 6 are designed. The upper and lower end walls of the movable groove 31 are provided with hooks 32. The operating component 5 simultaneously abuts against the end of the other swing arm 61 of the two linkage components 6. Thus, the upper and lower sides of the operating component 5 are linked with the upper and lower end walls of the limiting component 3 through a linkage component 6, making the force transmission more stable.

[0045] In the first embodiment, the axis of the linkage 6 is set in the front-back direction, that is, parallel to the side of the rod 2 and perpendicular to the sliding direction of the limiting member 3 and the operating member 5, so that the force transmission is more stable.

[0046] The back of the aforementioned rod 2 is provided with a wall seat groove 22; the wall seat 1 is located within the wall seat groove 22, and its front protrudes to form a protrusion 11, which is located on the side of the limiting member 3 facing away from the operating member 5; the side of the protrusion 11 facing the limiting member 3 is provided with a plurality of first protruding teeth 12 along the vertical direction, and the limiting member 3 is provided with a plurality of second protruding teeth 34 that mesh with the first protruding teeth 12. Thus, the first protruding teeth 12 that cooperate with the second protruding teeth 34 (i.e., the limiting member 3) are still collinear with the operating member 5 and the limiting member 3, and do not require a large space in the front-back direction, which can meet the need to design the product to be thinner.

[0047] Furthermore, the cross-section of the aforementioned wall base groove 22 is L-shaped, and guide flanges 23 extending in the vertical direction are formed on both sides of its opening. Guide grooves 13 are provided on both sides of the wall base 1 for sliding engagement with the guide flanges 23, which are used to guide the rod 1 to slide up and down and prevent it from shaking, making the structure more stable.

[0048] Meanwhile, end caps 9 are detachably installed at both ends of the aforementioned wall seat slide groove 22. The wall seat 1 moves and abuts against one end cap 9 as the rod 2 slides up and down. This allows the rod 2 to travel within a certain range relative to the wall seat 1, preventing excessive lifting and detachment from the wall seat 1. The end cap 9 is fixed to the end of the rod 2 by a pin 10, which can be prevented from coming off the end cap 9 by interference fit or snap-fit ​​connection. Specifically, the side of the rod 1 facing away from the operating member 5 is provided with a mounting slide groove 24. The end cap 9 is provided with a first protrusion 91 and a second protrusion 92 that are respectively tightly fitted to the ends of the wall seat slide groove 22 and the mounting slide groove 24. The end of the second protrusion 92 is split into two halves. The pin 10 passes through the second protrusion 92, one side wall of the wall seat slide groove 22 (near the mounting slide groove 24), and the first protrusion 91 in sequence, and is snap-fitted to the other side wall of the wall seat slide groove 22 (away from the mounting slide groove 24). This allows for a secure fixation of the end cap 9; simply insert the pin 10 to secure it. To remove the end cap 9, a flathead screwdriver can be inserted between the two halves of the second protrusion 92 and pried out the cap of the pin 10. In practical applications, walls may obstruct the movement of the lifting rod, and using self-tapping screws from the side could be limited by installation space constraints. This method, however, is easier to install and remove than screw fixing. Furthermore, the aforementioned mounting groove 24 can be used to secure the shower head socket of the handheld shower head, allowing for two-stage height adjustment via its own height adjustment and the height adjustment of the rod 2. This provides a wider range of motion and greater flexibility, and the maximum height of the rod 2 is not limited by installation space.

[0049] In addition, the aforementioned rod 2 has a cavity 25 on the side of the wall base slide groove 22 for the installation of the limiting member 3 (including the aforementioned mounting seat 7), and the cavity 25 is connected to the wall base slide groove 22.

[0050] refer to Figure 10 , Figure 11 The diagram illustrates a second embodiment of the present invention. The second embodiment shares most of the same structural design as the first embodiment, with the following differences: The aforementioned limiting member 3 and operating member 5 are directly assembled into a single structure, enabling them to move in the same direction. This eliminates the need for a linkage member 6 and its related structures (such as the movable groove 31 and hook 32). When the user needs to adjust the height of the rod 2, pulling the operating member 5 outward a certain distance will separate the limiting member 3 from the wall base 1 (i.e., the first protruding tooth 12 separates from the second protruding tooth 34). Specifically, the limiting member 3 has a connecting part 35 on its side facing the operating member 5. The operating member 5 and the connecting part 35 are detachably connected by bolts, snap-fit ​​connections, or other means. The circumferential surface of the operating member 5 has an operating flange 54 for easy removal.

[0051] In addition, this utility model also discloses a shower device, including the lifting rod structure shown in the first and second embodiments.

[0052] The aforementioned shower unit also includes an overhead shower head and a shower head socket for securing a handheld shower head; the overhead shower head is fixed to the upper end of the rod 2; the shower head socket is height-adjustable and fits into the mounting groove 24 on the side of the rod 2. The water path / pipe of the overhead shower head can be designed within the rod 2, with space reserved by widening the design, without occupying space in the front-to-back direction, thus continuing to meet the design requirements for a thinner product.

[0053] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
