Description

Technical Field

[0001] This utility model relates to the field of daily necessities technology, and in particular to a fixed base bracket. Background Technology

[0002] Clothes racks, as household items used daily, have become necessities for many families. They mainly come in wing-shaped, X-shaped, single-pole, and double-pole types. Among them, single-pole clothes racks consist of a round column and a fixed base hardware.

[0003] When existing fixed base brackets are fixed to the wall with nuts, the position of the single-pole clothes rack with clamps on it will never change. When the length of clothes drying on the single pole is too long, the fixed base bracket cannot adjust the height of the single pole. When clothes that are too long are hung to dry, their bottoms will touch the floor and stick to the dust on the floor, thus affecting the drying effect. Therefore, those skilled in the art have provided a fixed base bracket to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of existing fixed base brackets, which, when fixed to the wall with nuts, prevent the position of the single-pole clothes rack with clamps from changing. When the clothes drying on the single pole are too long, the fixed base bracket cannot adjust the height of the single pole. When drying clothes that are too long, the bottom of the clothes will stick to the floor and collect dust, thus affecting the drying effect. Therefore, a fixed base bracket is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixed base support, including a fixed base, wherein a height adjustment mechanism is provided in the middle of the front side of the fixed base;

[0006] The height adjustment mechanism includes an adjusting gear located in the middle of the rear side of the fixed base. The right end of the adjusting gear is meshed with a positioning toothed plate. Three equally spaced first closed-loop slide grooves are provided in the middle of the front surface of the fixed base. The middle of the front side of the adjusting gear is connected through the first closed-loop slide groove in the middle of the fixed base and is slidably connected with the first closed-loop slide groove in the middle. A sealing plate is slidably connected in the middle of the front surface of the fixed base. Three limiting blocks are fixedly connected in the middle of the rear surface of the sealing plate. The height of the sealing plate can be adjusted by sliding up and down along the first closed-loop slide groove through the three limiting blocks fixed in the rear side. The adjusting gear locks the height of the sealing plate after adjustment by meshing with the positioning toothed plate.

[0007] With the above technical solution, when adjusting the height, rotating the adjusting gear will move it upward a specified distance along the positioning tooth plate. This will cause the sealing plate connected to the front of the positioning tooth plate to slide steadily upward a specified distance along the first closed-loop slide groove under the restriction of the limiting column block. This will cause the clamping mechanism installed on the front of the sealing plate to move upward a specified height, so that the clothesline clamped by the clamping mechanism moves upward a specified height above the fixed base, making it easy to adjust the height of the clothesline without changing the position of the fixed base.

[0008] Furthermore, the front side of the sealing plate is provided with a clamping mechanism, which includes a U-shaped positioning plate. The U-shaped positioning plate is fixed to the front surface of the sealing plate. A push-pull slide rod is slidably connected to the middle of the inner side of the U-shaped positioning plate. A connecting column is fixedly connected to the rear side of the top of the push-pull slide rod. A second clamping claw is rotatably connected to the left end of the top of the U-shaped positioning plate. A first clamping claw is rotatably connected to the right end of the top of the U-shaped positioning plate. A second closed-loop slide groove is opened below the front surface of the first and second clamping claws. The connecting column is slidably connected to the bottom of the second and first clamping claws through the second closed-loop slide groove.

[0009] With the above technical solution, when clamping and fixing the clothes drying rod, one end of the clothes drying rod to be clamped is inserted into the cavity formed between the first clamping claw and the second clamping claw. Then, the push-pull slide rod is pulled down. The sliding push-pull slide rod will drive the first clamping claw and the second clamping claw connected to the outside of the second closed-loop slide groove to rotate around the central fixed shaft towards the inside and below of the U-shaped positioning plate through the connecting column rod fixed at the top and the second closed-loop slide groove slidably connected to the connecting column rod. This will cause the top of the first clamping claw and the second clamping claw to rotate towards the outer surface of the clothes drying rod and clamp onto the outer surface of the clothes drying rod to clamp and position the clothes drying rod.

[0010] Furthermore, a limiting cavity is provided at the middle of the left and right ends of the top of the U-shaped positioning plate. The second clamping claw and the first clamping claw are rotatably connected to the U-shaped positioning plate through the limiting cavity. A limiting hole is provided at the middle of the bottom inner side of the U-shaped positioning plate. The push-pull slide rod is slidably connected to the U-shaped positioning plate through the limiting hole. Multiple fixing holes are evenly provided at the middle of the front surface of the push-pull slide rod.

[0011] With the above technical solution, when the first clamping claw and the second clamping claw rotate up and down, the rotation trajectory of the first clamping claw and the second clamping claw is limited by the limiting cavity groove, and the trajectory of the push-pull slide rod sliding up and down is limited by the limiting hole during the process of the push-pull slide rod sliding up and down.

[0012] Furthermore, a clamping hole is provided in the middle of the front side of the limiting hole, and a fixing nut for fixing the fixing hole is clamped inside the clamping hole. The fixing nut is located in the middle of the bottom end of the front surface of the U-shaped positioning plate.

[0013] With the above technical solution, when the fixing hole opened at the corresponding position of the push-pull slide rod slides into the clamp hole opened in the middle of the front side of the limiting hole, and then the fixing nut is rotated so that the fixing nut passes through the clamp hole and the fixing hole at the corresponding position of the push-pull slide rod, the adjusted position of the push-pull slide rod is fixed, which is convenient for fixing the adjusted position of the push-pull slide rod and helps to prevent the adjusted position of the push-pull slide rod from changing.

[0014] Furthermore, the middle part of the front side of the adjusting gear passes through the first closed-loop slide groove opened in the middle part of the front side of the fixed base and the bottom end of the front surface of the sealing plate in sequence. The bottom end of the front surface of the sealing plate is provided with a knob. The middle part of the rear side of the knob is fixedly connected to the middle part of the front side of the adjusting gear. The left end of the adjusting gear is provided with a positioning clamp.

[0015] With the above technical solution, when the adjusting gear is rotated, the operator manually rotates the knob. When the knob is rotated by external thrust, it will drive the adjusting gear fixedly connected in the middle of the rear to rotate. The rotating adjusting gear will move up or down a specified distance along the positioning tooth plate meshing with the right end. During the rotation and movement of the adjusting gear, the positioning clamp limits the trajectory of the adjusting gear's up and down movement.

[0016] Furthermore, the knob is clamped with a clamping plate on its outer side, and the clamping plate is slidably connected to the bottom of the front side of the sealing plate;

[0017] With the above technical solution, when the knob is not rotating, pushing the clamp plate in the direction of the knob will cause the clamp plate to clamp onto the outside of the knob and fix the knob, which helps to prevent the knob from rotating.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, by setting an adjusting gear, a positioning tooth plate, a sealing plate, a limiting column, and a first closed-loop slide groove, when adjusting the height, rotating the adjusting gear will move the rotating adjusting gear upward along the positioning tooth plate by a specified distance. This will cause the sealing plate connected to the front side of the positioning tooth plate to slide steadily upward along the first closed-loop slide groove to the fixed base by a specified distance under the restriction of the limiting column. This will cause the clamping mechanism installed on the front side of the sealing plate to move upward by a specified height, so that the clothes drying rod clamped on the clamping mechanism moves upward to the fixed base by a specified height. This makes it easy to adjust the height of the clothes drying rod without changing the position of the fixed base, which is beneficial to improving the use effect of the fixed base.

[0020] 2. In this utility model, by setting a first clamping claw, a second clamping claw, a push-pull slide rod, a connecting column rod, a second closed-loop slide groove, and a U-shaped positioning plate, when clamping and fixing the clothes drying rod, one end of the clothes drying rod to be clamped is inserted into the cavity formed between the first clamping claw and the second clamping claw. Then, the push-pull slide rod is pulled down. The sliding push-pull slide rod will drive the first clamping claw and the second clamping claw connected to the outside of the second closed-loop slide groove to rotate around the central fixed shaft towards the inside and below of the U-shaped positioning plate, thereby driving the top of the first clamping claw and the second clamping claw to rotate towards the outer surface of the clothes drying rod and clamp onto the outer surface of the clothes drying rod to clamp and position the clothes drying rod, which is convenient for clamping and fixing clothes drying rods of different sizes.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Reference Figure 1-6 One embodiment of this utility model is a fixed base support, including a fixed base 1, and a height adjustment mechanism is provided in the middle of the front side of the fixed base 1.

[0031] The height adjustment mechanism includes an adjusting gear 13, located in the middle of the rear side of the fixed base 1. A positioning toothed plate 12 is meshed with the right end of the adjusting gear 13. Three equally spaced first closed-loop grooves 2 are formed in the middle of the front surface of the fixed base 1. The middle of the front side of the adjusting gear 13 is connected through to and slidably connected to the first closed-loop grooves 2 in the middle of the fixed base 1. A sealing plate 4 is slidably connected to the middle of the front surface of the fixed base 1. Three limiting blocks 11 are fixedly connected to the middle of the rear surface of the sealing plate 4. The sealing plate 4 can be adjusted in height by sliding up and down along the first closed-loop grooves 2 via the three fixed limiting blocks 11 on its rear side. The adjusting gear 13 engages with the positioning gear plate 12 to lock the height of the sealing plate 4 after adjustment. The middle of the front side of the adjusting gear 13 passes through the first closed-loop groove 2 opened in the middle of the front side of the fixed base 1 and the bottom end of the front surface of the sealing plate 4. A knob 23 is provided at the bottom end of the front surface of the sealing plate 4. The middle of the rear side of the knob 23 is fixedly connected to the middle of the front side of the adjusting gear 13. A positioning clamping plate 14 is provided at the left end of the adjusting gear 13. A clamping plate 20 is clamped on the outside of the knob 23. The clamping plate 20 is slidably connected to the bottom of the front side of the sealing plate 4. Multiple threaded holes 3 are evenly opened on the outer edge of the front surface of the fixed base 1. A guide block is fixedly connected to one end of the rear surface of the clamping plate 20. 21. A guide groove 19 is provided on the outer side of the guide block 21. The guide groove 19 is located below the front surface of the sealing plate 4 and above the knob 23. Multiple positioning holes 24 are evenly provided on the outer surface of the knob 23. A positioning pin 22 is fixedly connected to the middle of one end of the clamp plate 20. The positioning pin 22 can engage with the positioning holes 24. When adjusting the height, the operator manually rotates the knob 23. When the knob 23 is rotated by external force, it will drive the adjusting gear 13 fixedly connected to the middle of the rear side to rotate. The rotating adjusting gear 13 will move upward a specified distance along the positioning tooth plate 12, thereby driving the sealing plate 4 connected to the front side of the positioning tooth plate 12 to the limiting pin 11. Under the constraint, the clamping plate 20 slides steadily upwards along the first closed-loop slide groove 2 to the fixed base 1 for a specified distance, thereby driving the clamping mechanism for clamping the drying rod installed on the front side of the sealing plate 4 to move upwards to a specified height. This causes the drying rod clamped on the clamping mechanism to move upwards to the fixed base 1 to a specified height, pushing the clamping plate 20 in the direction of the knob 23. This causes the clamping plate 20 to slide along the guide groove 19 in the direction of the knob 23 through the guide block 21 fixed on the rear side. This causes the positioning pin block 22 fixedly connected to the middle of one end of the clamping plate 20 to engage with the positioning hole 24 opened at the corresponding position on the outer surface of the knob 23, so that the clamping plate 20 clamps and positions the knob 23 after rotation adjustment.

[0032] Preferably, the sealing plate 4 has a clamping mechanism on its front side, which includes a U-shaped positioning plate 5. The U-shaped positioning plate 5 is fixed to the front surface of the sealing plate 4. A push-pull slide rod 9 is slidably connected to the middle of the inner side of the U-shaped positioning plate 5. A connecting column rod 18 is fixedly connected to the rear side of the top of the push-pull slide rod 9. A second clamping claw 7 is rotatably connected to the left end of the top of the U-shaped positioning plate 5. A first clamping claw 6 is rotatably connected to the right end of the top of the U-shaped positioning plate 5. A second closed-loop sliding groove 8 is opened below the front surface of the first clamping claw 6 and the second clamping claw 7. The connecting column rod 18 passes through... The second closed-loop slide groove 8 is slidably connected to the bottom of the second clamping claw 7 and the first clamping claw 6. A limiting cavity groove 16 is opened in the middle of the left and right ends of the top of the U-shaped positioning plate 5. The second clamping claw 7 and the first clamping claw 6 are rotatably connected to the U-shaped positioning plate 5 through the limiting cavity groove 16. A limiting hole 15 is opened in the middle of the bottom inner side of the U-shaped positioning plate 5. The push-pull slide rod 9 is slidably connected to the U-shaped positioning plate 5 up and down through the limiting hole 15. Multiple fixing holes 17 are evenly opened in the middle of the front surface of the push-pull slide rod 9. A clamp is opened in the middle of the front side of the limiting hole 15. The inner side of the clamp hole has a fixing nut 10 for fixing the fixing hole 17. The fixing nut 10 is located in the middle of the bottom end of the front surface of the U-shaped positioning plate 5. When clamping the clothes drying rod, one end of the clothes drying rod to be clamped is inserted into the clamping cavity formed between the first clamping claw 6 and the second clamping claw 7. Then, the push-pull slide rod 9 is pulled down, so that the push-pull slide rod 9 slides down along the limiting hole 15 opened in the middle of the bottom end of the U-shaped positioning plate 5. The sliding push-pull slide rod 9 will slide down through the connecting column rod 18 fixedly connected to the top and the sliding column rod 18. The second closed-loop slide groove 8, which is dynamically connected, drives the first clamping claw 6 and the second clamping claw 7, which are connected to the outer side of the second closed-loop slide groove 8, to rotate around the central fixed shaft and towards the inner side of the U-shaped positioning plate 5. This causes the tops of the first clamping claw 6 and the second clamping claw 7 to rotate towards the outer surface of the drying rod and clamp onto the outer surface of the drying rod to clamp and position the drying rod. At this time, the fixing nut 10 is rotated so that the fixing nut 10 passes through the clamping hole and the fixing hole 17 at the corresponding position of the push-pull slide rod 9, thereby fixing the adjusted position of the push-pull slide rod 9.

[0033] Working principle: In use, the mounting nut is used to install and fix the fixing base 1 in the designated position through the threaded hole 3. Then, one end of the clothes drying rod to be clamped is inserted into the clamping cavity formed between the first clamping claw 6 and the second clamping claw 7. Then, the push-pull slide rod 9 is pulled down, causing the push-pull slide rod 9 to slide down along the limiting hole 15 opened in the middle of the bottom end of the U-shaped positioning plate 5. The sliding push-pull slide rod 9 will drive the second closed-loop slide groove 8 outward through the connecting column rod 18 fixedly connected to the top and the second closed-loop slide groove 8 slidably connected to the connecting column rod 18. The first clamping claw 6 and the second clamping claw 7, connected to the sides, rotate around the centrally fixed shaft towards the lower inner side of the U-shaped positioning plate 5, thereby causing the tops of the first clamping claw 6 and the second clamping claw 7 to rotate towards the outer surface of the clothes drying rod and clamp onto the outer surface of the clothes drying rod for clamping and positioning. At this time, rotating the fixing nut 10 causes the fixing nut 10 to pass through the clamping hole and the fixing hole 17 at the corresponding position of the push-pull slide rod 9, thereby fixing the adjusted position of the push-pull slide rod 9, completing the installation and fixing of the clothes drying rod. When it is necessary to adjust the clothes drying rod, the clothes drying rod can be adjusted. When adjusting the height of the clothes rod, manually rotate knob 23. When knob 23 is rotated by external force, it will drive the adjusting gear 13 fixedly connected to the middle of the rear to rotate. The rotating adjusting gear 13 will move upward along the positioning tooth plate 12 a specified distance, thereby driving the sealing plate 4 connected to the front of the positioning tooth plate 12 to slide steadily upward along the first closed-loop slide groove 2 to the fixed base 1 a specified distance under the restriction of the limiting column block 11. This will drive the clamping mechanism for clamping the clothes rod installed on the front of the sealing plate 4 to move upward by a specified distance. The clothesline is adjusted to a certain height, causing the clothesline clamped by the clamping mechanism to move upwards to the fixed base 1 by a specified height. The clamping plate 20 is pushed in the direction of the knob 23, causing the clamping plate 20 to slide along the guide groove 19 through the guide block 21 fixed on the rear side towards the knob 23. The positioning pin 22 fixedly connected to the middle of one end of the clamping plate 20 is engaged in the positioning hole 24 opened at the corresponding position on the outer surface of the knob 23, so that the clamping plate 20 clamps and positions the knob 23 after rotation adjustment, thus completing the height adjustment of the clothesline.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
