Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of trace element analyzers, specifically relating to an adjustable base structure for a trace element analyzer. Background Technology
[0002] In the application scenarios of trace element analyzers, the stability and adjustability of the base structure are crucial. Currently, there are various adjustable base structures for trace element analyzers on the market. Some existing technologies use a motor to drive a screw, which in turn drives a transmission rod and a connecting block to adjust the height of the analyzer in order to meet the user's needs for operational comfort.
[0003] However, existing technologies still have shortcomings in terms of ease of adjustment and flexibility. On the one hand, most existing adjustment methods can only achieve overall synchronous lifting and lowering. When facing uneven placement surfaces or when fine angle adjustments are required for the analyzer, they cannot precisely adjust a single foot, resulting in low adjustment efficiency and difficulty in meeting the needs of complex operating environments. On the other hand, when a large height adjustment of the analyzer is required, existing adjustment mechanisms are cumbersome to operate and cannot quickly achieve the ideal height change, affecting work efficiency.
[0004] The present invention aims to overcome the above-mentioned defects of the prior art and provide an adjustable base structure for a trace element analyzer. Utility Model Content
[0005] The purpose of this invention is to provide an adjustable base structure for a trace element analyzer, which can achieve both coarse adjustment by rotating any knob to drive the other feet to rise and fall synchronously, and can disconnect the linkage when needed to switch a single foot to an independent adjustment mode.
[0006] The specific technical solution adopted by this utility model is as follows:
[0007] An adjustable base structure for a trace element analyzer includes a base plate. Threaded rods are rotatably connected to four end positions on the bottom of the base plate. Ground feet are threaded to the bottom outer side of each threaded rod. Limiting strips are provided on the outer side of each ground foot. A limiting plate that is slidably connected to the limiting strips is fixed to the bottom of the base plate. A synchronous transmission mechanism is installed on the bottom of the base plate.
[0008] The synchronous transmission mechanism includes a rotating column fixed to the outside of the threaded rod and near the top end. A driving gear is installed on the outside of the rotating column, and a guide structure for guiding the driving gear is provided on the outside of the rotating column. A rotating rod is rotatably connected to the bottom of the base plate and on one side of the multiple threaded rods. A driven gear that meshes with the driving gear is fixed to the bottom of the rotating rod.
[0009] A drive wheel is installed on the outer side of the rotating rod at each of two adjacent base plate end positions, and a drive belt is installed between each of two adjacent drive wheels.
[0010] The guide structure includes a guide groove disposed inside the rotating column. A central pad is fixed in the middle of the guide groove, and the central pad divides the upper and lower parts of the guide groove into two mounting slots. The driving gear is located in one of the mounting slots. The driving gear is located in the upper mounting slot and is not meshed with the driven gear. The driving gear is located in the lower mounting slot and is meshed with the driven gear.
[0011] At least one guide bar is fixed inside the guide groove, and the guide bar is slidably connected to the drive gear.
[0012] The outer side of the bottom of the driving gear and the outer side of the top of the driven gear are both provided with inclined surfaces.
[0013] The central pad is made of a flexible material, such as rubber or silicone.
[0014] A rotating bar is rotatably connected to the bottom of the base plate and inside each of the transmission belts, and a tensioning abutment block is fixed to the bottom of the rotating bar and inside the inner wall of the transmission belt, the tensioning abutment block being in contact with the inner wall of the transmission belt.
[0015] The technical effects achieved by this utility model are as follows:
[0016] This invention enables the synchronous up-and-down adjustment of multiple footrests through the meshing connection of the driving gear and the driven gear. By de-meshing the driving gear and the driven gear, the height of a single footrest can be adjusted individually. This allows for both coarse adjustment by rotating any knob to drive the synchronous up-and-down movement of other footrests, and the ability to disconnect the linkage when needed to switch a single footrest to an independent adjustment mode. This significantly improves the convenience, flexibility, and adaptability to different usage scenarios. Attached Figure Description

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0026] like Figures 1-6 As shown, an adjustable base structure for a trace element analyzer includes a base plate 1, on which the trace element analyzer is mounted. Threaded rods 2 are rotatably connected to the four ends of the base plate 1. Foot 3 is threadedly connected to the bottom of the outer side of each threaded rod 2. The bottom of each foot 3 is provided with an anti-slip rubber pad. The surface of the pad has cross-shaped anti-slip patterns, which increases friction with the supporting surface. The rubber material also has a shock-absorbing and buffering effect, improving the stability of the equipment. The pad contacts the table or ground, ensuring sufficient contact area and thus improving the support effect of the foot 3. A limit strip 6 is provided on the outer side of the foot 3, and a limit plate 5, which is slidably connected to the limit strip 6, is fixed to the bottom of the base plate 1.
[0027] When adjusting the height of the base plate 1, the threaded rod 2 can be screwed on, and then the threaded rod 2 is connected to the foot 3. The foot 3 can move up and down through the sliding connection between the limiting strip 6 on the foot 3 and the limiting plate 5, thereby adjusting the height of the base plate 1. Furthermore, the limiting plate 5 and the limiting strip 6 adopt a dovetail groove fit structure. The cross-section of the limiting strip 6 is T-shaped, which can prevent the foot 3 from shifting laterally during the lifting process and ensure the vertical lifting accuracy.
[0028] A synchronous transmission mechanism is installed at the bottom of the base plate 1.
[0029] See attached document Figures 2-3The synchronous transmission mechanism includes a rotating column 4 fixed on the outside of the threaded rod 2 and near the top. A drive gear 7 is installed on the outside of the rotating column 4. A guide structure for guiding the drive gear 7 is provided on the outside of the rotating column 4. A rotating rod 8 is rotatably connected to the bottom of the base plate 1 and on one side of the multiple threaded rods 2. A driven gear 9 that meshes with the drive gear 7 is fixed at the bottom of the rotating rod 8. Through the guide structure, the drive gear 7 can slide on the rotating column 4. When the drive gear 7 slides to other positions of the rotating column 4 and does not mesh with the driven gear 9, the user can adjust the height of the foot 3 individually when turning one of the threaded rods 2, fine-tune the foot 3 at a certain end position, and adapt to the slope of the table or the ground, etc.
[0030] A transmission wheel 10 is installed on the outer side of the rotating rod 8 at the foot position of each two adjacent base plates 1. A transmission belt 11 is installed between each two adjacent transmission wheels 10. The transmission belt 11 is a rubber synchronous belt, and its inner surface can be provided with teeth to cooperate with the tooth grooves of the transmission wheel 10, so as to avoid transmission slippage.
[0031] When one of the rotating columns 4 is turned, the driving gear 7 can be driven to rotate. Through the meshing connection between the driving gear 7 and the driven gear 9, the driven gear 9 and the rotating rod 8 can be driven to rotate. This causes the rotating rod 8 to drive the transmission wheel 10 on it to rotate. The transmission wheel 10 drives the transmission belt 11 to drive the transmission. The transmission belt 11 drives the rotating rods 8 and transmission wheels 10 on the other end feet to rotate. The driven gears 9 at the other end feet rotate and drive the driving gear 7 to rotate, thereby simultaneously driving the multiple foot feet 3 to rotate. This allows the multiple foot feet 3 to move up and down at the same time, which facilitates the adjustment of the height of the base plate 1.
[0032] See attached document Figure 4 The guide structure includes a guide groove 18 disposed inside the rotating column 4. A central pad 12 is fixed in the middle of the guide groove 18. The central pad 12 divides the upper and lower parts of the guide groove 18 into two mounting grooves 13. The driving gear 7 is located in one of the mounting grooves 13. The driving gear 7 is located in the upper mounting groove 13 and is not meshed with the driven gear 9. The driving gear 7 is located in the lower mounting groove 13 and is meshed with the driven gear 9.
[0033] When the height of a single foot 3 needs to be adjusted individually, the drive gear 7 can be moved upwards, passing the central pad 12 and sliding into the upper mounting groove 13. The central pad 12 prevents the drive gear 7 from falling. When the height of multiple foot 3s needs to be adjusted simultaneously, the drive gear 7 can be moved downwards, passing the central pad 12 and sliding into the lower mounting groove 13, where it meshes with the driven gear 9. Furthermore, the central pad 12 is made of a flexible material, such as rubber or silicone. This design causes the central pad 12 to deform upon contact with it as the drive gear 7 moves upwards from the lower mounting groove 13. When the drive gear 7 moves to the upper mounting groove 13, the central pad 12 returns to its original shape, preventing the drive gear 7 from falling. The elastic deformation of the flexible material also provides damping, preventing accidental slippage of the drive gear 7. (See attached diagram.) Figure 5 An inclined surface 15 is provided on the outer side of the bottom of the driving gear 7 and the outer side of the top of the driven gear 9. The inclined surface 15 allows the driving gear 7 to easily contact the driven gear 9 when it moves down. The inclined surface 15 also allows the teeth of the driving gear 7 to insert into the tooth gap of the driven gear 9. At least one guide bar 14 is fixed in the guide groove 18 and is slidably connected to the driving gear 7. The guide bar 14 limits the rotation of the driving gear 7, preventing it from spinning freely. This restricts the driving gear 7 to slide axially and prevents it from rotating circumferentially.
[0034] A rotating bar 16 is rotatably connected to the bottom of the base plate 1 and inside each transmission belt 11. The rotating bar 16 is interference-fitted with the base plate 1, so that after the rotating bar 16 rotates, it will not rotate again unless subjected to a large external force. A tensioning abutment block 17 is fixed to the bottom of the rotating bar 16 and inside the transmission belt 11. The tensioning abutment block 17 is in contact with the inner wall of the transmission belt 11. With this arrangement, when the transmission belt 11 becomes loose, the rotating bar 16 can be turned, causing the rotating bar 16 to drive the tensioning abutment block 17 to rotate. The tensioning abutment block 17 abuts against the transmission belt 11 through its two ends, thereby tensioning the transmission belt 11. Wheels are provided at both ends of the tensioning abutment block 17. The wheels are provided so that they contact the transmission belt 11 and reduce the friction between them.
[0035] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
