Description

Technical Field

[0001] The invention relates to a groove nut and a tripod containing the groove nut, and in particular to a groove nut that can be used on an elevated floor and a tripod containing the groove nut. Background Art

[0002] Nowadays, elevated floors have been widely used in computer rooms, clean rooms and other places. The elevated floor generally includes: a number of tripods, a number of beams and a number of elevated floors, which can form a highly flat plane above the ground, facilitate the installation of pipelines and facilitate the control of cleanliness levels. With the development of technology, many tripods with different structures have appeared on the market. The basic structure of the existing commonly used tripods generally includes a supporting tube body, a pipe sleeve arranged on the top of the supporting tube body and an upper base. The upper base is composed of a support plate and a screw rod arranged at the bottom of the support plate. A positioning nut is provided on the screw rod and is threadedly connected to the pipe sleeve. After adjusting the height of the upper base, the pipe sleeve and the screw rod are fastened together by the positioning nut, so as to facilitate the adjustment of the height of the upper base.

[0003] The existing commonly used tripods need to first thread the positioning nut onto the screw, and then thread the screw onto the pipe sleeve to adjust the height. The length of the screw is the adjustable height range of the upper base. In other words, if you want the upper base to have a larger adjustable height range, or if you need a larger usable space under the elevated floor, you need to use a longer screw. However, using a longer screw and supporting tube will make it very time-consuming and inconvenient to install to thread the positioning nut onto the screw and the screw onto the pipe sleeve. Moreover, when the pipe sleeve and the screw are fastened together by the positioning nut, there will be problems such as being difficult to adjust if it is too tight, and easy to get loose if it is too loose.

[0004] In view of this, the inventor has painstakingly pondered and actively researched, combined with many years of experience in related product research, and through continuous testing and improvement, finally designed the present invention. Summary of the invention

[0044] The technical solution of the present invention will be clearly and completely described below through specific implementation methods. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0045] Figure 1 to Figure 5 This is the first embodiment of the present invention. Figure 1 to Figure 5 As shown, the groove nut 100 provided by the present invention is used between the upper base 3 and the sleeve 2 of a tripod 200 containing the groove nut 100, and includes: a nut body 4, having a first end face 41 and a second end face 42, a screw hole 43 extending from the first end face 41 to the second end face 42 is provided at the center of the nut body 4, and the second end face 42 has at least one groove 44. With this structure, installation can be facilitated and stability can be increased. This will be described in detail below.

[0046] The groove nut 100 can be used on the footstand of the elevated floor to form a footstand 200 with a groove nut, and the footstand 200 with a groove nut can be used to support the elevated floor 202. The footstand 200 with a groove nut includes: a supporting tube 1, a bottom plate 11 is provided at the bottom and can stand upright on the ground 201, and the top of the supporting tube 1 has a top opening 12. A sleeve 2 has a tapered tube 21 with an outer diameter gradually increasing from the bottom to the top, a through hole 22 is provided at the center of the tapered tube 21 from the top to the bottom, and a flange 23 protruding outward is provided at the top of the tapered tube 21, and the upper surface 231 of the flange 23 has at least one convex point 24 protruding upward. The tapered tube 21 is arranged in the top opening 12 of the supporting tube 1, and the flange 23 is placed on the top of the tube wall of the supporting tube 1. An upper base 3 is composed of a support plate 31 and a screw rod 32 arranged at the bottom of the support plate 31. A groove nut 100 has a nut body 4, the nut body 4 has a first end face 41 and a second end face 42, a screw hole 43 is provided at the center of the nut body 4, which runs from the first end face 41 to the second end face 42, and the second end face 42 has at least one groove 44. The nut body 4 is screwed on the screw rod 32, and the bottom end of the screw rod 32 is inserted into the through hole 22 of the sleeve 2, so that the groove 44 on the nut body 4 is engaged with the protrusion 24 on the sleeve 2.

[0047] Through the above structure, the present invention can be applied to tripods with lower load bearing capacity, especially tripods 200 for elevated floors 202 in offices. The tripod 200 is less than 35 cm and bears a load of more than 3 tons. If a larger load needs to be carried, the diameter of the support tube 1 needs to be increased. In addition, compared with the common tripod (not shown in the figure), the present invention is connected by the engagement of the groove 44 on the nut body 4 with the protrusion 24 on the sleeve 2, which does not require the cumbersome step of threading the screw rod on the sleeve, and can be easily installed. Furthermore, the commonly used positioning nuts have the problems of being difficult to adjust if locked too tightly, and being easy to loosen if locked too loosely. In the present invention, the cooperation between the groove 44 on the nut body 4 and the protrusion 24 on the sleeve 2 does not have the problem of being locked too tightly or too loosely, and the stability is higher. In addition. See also Figure 2 and Figure 5 As shown, the aforementioned support plate 31 may have at least one floor fixing hole 311 and at least one beam fixing hole 312, and the elevated floor 202 is composed of a panel 2021 and a side rib 2022 arranged below the panel 2021, and the outer edge of the panel 2021 has a part of the structure protruding from the side rib 2022 to form a floor flange 2023. A beam 33 may span between adjacent foot frames 200, and the two ends of the beam 33 are respectively fixed to the beam fixing holes 312 of the support plate 31. The elevated floor 202 may be a steel or aluminum floor, and the four corners of the elevated floor 202 may be fixed to the floor fixing holes 311 on the support plate 31 of the foot frame 200 using a bolt 2024, and the floor flange 2023 of the elevated floor 202 is supported on the beam 33, and adjacent floor flanges 2023 are simultaneously supported on the same beam 33. As can be seen from the foregoing, four corners of a raised floor 202 can be supported by four tripods 200 . On the other hand, one tripod 200 can also support one corner of four raised floors 202 .

[0048] The nut body 4 can be a hexagonal prism with six side faces 45, which can be easily rotated by tools. The groove 44 of the second end face 42 can be located at the center of any side face 45 on the nut body 4, so that the side faces 45 corresponding to the groove 44 of the second end face 42 are evenly stressed.

[0049] The protrusion 24 on the sleeve 2 can be a structure formed on the upper surface of the flange 23 by, for example, stamping, which can be easily manufactured.

[0050] The outer diameter of the top section of the tapered tube body 21 of the sleeve 2 may be slightly larger than the top opening 12 of the support tube body 1 , so that the sleeve 2 and the support tube body 1 are connected together in an interference fit manner.

[0051] Figure 6 This is the second embodiment of the present invention. Figure 6As shown, the second end face 42a of the nut body 4a may further have six grooves 44a, so that when the step of making the grooves 44a of the second end face 42a correspond to the protrusions 24a of the sleeve 2a is performed, after the nut body 4a is adjusted in height on the screw rod 32a, the nut body 4a and the sleeve 2a can correspond to each other by a maximum of one-sixth of a turn relative to each other, thereby facilitating positioning. In addition, the upper surface of the flange 23a of the sleeve 2a may further have two upwardly protruding protrusions 24a or more protrusions (not shown in the figure) to increase stability.

[0052] Figures 7-8 This is the third embodiment of the present invention. Figures 7-8 As shown, the sleeve 2b can also be integrally formed by, for example, die casting, thereby forming a convex point 24b on the upper surface 231b of the flange 23b. The cross section of the convex point 24b can be triangular, and its two sides are vertical surfaces 241b arranged perpendicular to the flange 23b, and have an inclined surface 242b, so as to further increase the stability when the sleeve 2b is engaged with the groove nut 4b, and prevent the sleeve 2b and the groove nut 4b from rotating relative to each other. In addition, corresponding to the structure of the convex point 24b with a triangular cross section, the groove 44b of the groove nut 4b also has two vertical parts 441b and an inclined part 442b corresponding to the vertical surface 241b and the inclined surface 242b.

[0053] Fig. 9 and Fig.10 This is the fourth and fifth embodiment of the present invention. Figures 9-10 As shown, the second end faces 42c, 42d of the nut bodies 4c, 4d may further have four grooves 44c or two grooves 44d, and the remaining structures are the same as those of Figure 7 The groove nut 4b in the middle is the same, which facilitates positioning and increases stability.

[0054] Fig.11 This is the sixth embodiment of the present invention. Fig.11 As shown, depending on the change in usage requirements, the elevated floor 202e can also be installed only on the foot frame 200e without using the aforementioned beam-related structure.

[0055] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
