Description

Technical Field

[0001] The utility model relates to the field of lifting tables, in particular to a structure for quickly disassembling and assembling table legs. Background Art

[0002] In the field of single-motor lifting tables, low-cost packaging and transportation and easy and convenient installation are often mentioned separately, but it is difficult to have both because in the existing technology, there is a certain contradiction between the two. Low-cost packaging and transportation means more parts need to be split and packaged, shrink-wrapped and the transportation space needs to be reasonably arranged. Easy and convenient installation means integrating and packaging the parts as much as possible so that consumers can assemble them quickly. Therefore, reducing the difficulty of installation and achieving quick disassembly and assembly under the premise of low cost is our focus.

[0003] Traditional single-motor drive lift tables basically place the gearbox inside the lift column. During packaging, the motor and drive hexagonal rod are placed separately to obtain lower packaging and transportation costs. However, this packaging loses the simplicity and convenience during installation. Customers need to insert the longer drive rod into the gearbox of the column, which is inconvenient to operate. Customers often need to spend more time and energy to install and debug the installation distance and balance of the left and right lift columns, which brings great troubles to customers. At the same time, the longer drive rod consumes greater packaging costs. Summary of the invention

[0004] In order to solve the above technical problems, the utility model provides a structure for quick disassembly and assembly of table legs, comprising a linkage rod and two columns located on both sides of the linkage rod, wherein the two columns are provided with a transmission rod coaxial with the linkage rod, and the transmission rod and the linkage rod are arranged at intervals from each other; a connecting piece capable of selective sliding is provided at both ends of the linkage rod, and the structure comprises a waiting state and an assembled state, wherein the connecting piece is located on the linkage rod and is separated from the transmission rod in the waiting state, and when the connecting piece is slid toward the transmission rod and connected with the transmission rod and the linkage rod, the structure is in the assembled state; the linkage rod and the transmission rod are connected by a slidable connecting piece, so the connection between the linkage rod and the transmission rod can be directly achieved by sliding the connecting piece, and the transmission connection between the two can also be achieved, and the installation is fast and simple; in this scheme, the transmission rod located on the column does not require excessive packaging of the column, nor does it have an adverse effect on the occupied space, and even when the transmission rod does not protrude from the column, the existence of the transmission rod will not affect the packaging and transportation of the column, and the corresponding linkage rod length is shorter than that of the traditional transmission rod, and the packaging and transportation cost can also be reduced.

[0005] The technical solution of the utility model is achieved in this way:

[0006] A structure for quick disassembly and assembly of table legs comprises a linkage rod and two columns, wherein the linkage rod is arranged between the two columns, a transmission rod coaxial with the linkage rod is arranged on the column, the linkage rod is configured to be transmission-connected to a motor, and the transmission rod is configured to be transmission-connected to a push rod assembly in the column; the transmission rod and the linkage rod are arranged at intervals from each other; connecting pieces are arranged at both ends of the linkage rod, and the connecting pieces are selectively slidably arranged on the linkage rod, and the structure comprises a waiting state and an assembled state, wherein in the waiting state, the connecting piece is located on the linkage rod and the transmission rod is separated from the connecting piece; when the waiting state is switched to the assembled state, the connecting piece slides toward the transmission rod along the length direction of the linkage rod; in the assembled state, the connecting piece spans the interval between the transmission rod and the linkage rod, and is connected to the transmission rod and the linkage rod.

[0007] In this solution, the two ends of the original traditional transmission rod are cut off, so that the two short transmission rods at the ends are always inserted on the column as the end transmission rods. When the lifting table is installed, it is only necessary to connect the linkage rod as the middle transmission rod with the two transmission rods as the end transmission rods; and the linkage rod and the transmission rod are connected by a slidable connecting piece, so the connection between the linkage rod and the transmission rod can be directly achieved by sliding the connecting piece, and the transmission connection between the two can also be achieved, and the installation is fast and simple; in this solution, the transmission rod located on the column does not require too much packaging of the column, nor will it cause adverse effects on the occupied space. Even when the transmission rod does not protrude from the column, the existence of the transmission rod will not affect the packaging and transportation of the column. The corresponding linkage rod length is shorter than that of the traditional transmission rod, and the packaging and transportation cost can also be reduced.

[0008] Preferably, the connecting piece is provided with an adjustable fastener. In the ready-to-install state, the adjustable fastener is loosened, and the connecting piece and the linkage rod can slide relative to each other; in the assembled state, the adjustable fastener is locked, and the connecting piece is locked with the linkage rod and the transmission rod respectively. The adjustable fastener is used to control the selective sliding of the connecting piece. When the adjustable fastener is loosened, the connecting piece can slide.

[0009] Preferably, the adjustable fasteners are two screws arranged at intervals.

[0010] Preferably, the transmission rod protrudes from the column toward the linkage rod. The transmission rod protrudes from the column, which is convenient for the connecting piece to slide onto the transmission rod and also convenient for locking the adjustable fastener on the connecting piece.

[0011] Preferably, the length of the transmission rod protruding from the surface of the column is in the range of 40-46 mm. The length of the transmission rod is much shorter than that of the linkage rod. When the transmission rod is in a shorter length, the packaging and transportation cost of the column can also be maintained at a substantially unchanged level.

[0012] Preferably, a avoidance hole is provided on the column, and the avoidance hole is located between the linkage member and the transmission member. When switching from the ready-to-install state to the assembled state, the connecting member enters the avoidance hole and is connected to the transmission rod. The transmission rod is located inside the column, and the connecting member enters the column through the avoidance hole and is connected to the transmission rod, thereby achieving the unchanged packaging and transportation cost of the column, and further reducing the packaging and transportation cost of the linkage rod.

[0013] Preferably, the length of the connecting member is 80-85 mm. The connecting member has sufficient length to ensure stable connection with the linkage rod and the transmission rod.

[0017] In this solution, the two ends of the original traditional transmission rod are cut off, so that the two short transmission rods at the ends are always inserted on the column as the end transmission rods. When the lifting table is installed, it is only necessary to connect the linkage rod as the middle transmission rod with the two transmission rods as the end transmission rods; and the linkage rod and the transmission rod are connected by a slidable connecting piece, so the connection between the linkage rod and the transmission rod can be directly achieved by sliding the connecting piece, and the transmission connection between the two can also be achieved, and the installation is fast and simple; in this solution, the transmission rod located on the column does not require too much packaging of the column, nor will it cause adverse effects on the occupied space.

Implementation

[0028] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0030] In the description of the present invention, the terms "first", "second", "third", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0031] The specific implementation of the utility model is as follows:

[0032] like Figure 6 , 7As shown in Figures 9, the utility model provides a structure for quick disassembly and assembly of table legs, including a linkage rod 1 and two columns 2, the linkage rod 1 is arranged between the two columns 2, and a transmission rod 3 coaxial with the linkage rod 1 is provided on the column 2, the linkage rod 1 is configured to be transmission-connected to the motor 7, and the transmission rod 3 is configured to be transmission-connected to the push rod assembly in the column 2; the transmission rod 3 and the linkage rod 1 are spaced apart from each other; connecting members 4 are provided at both ends of the linkage rod 1, and the connecting member 4 is selectively slidably arranged on the linkage rod 1, and the structure includes a waiting state and an assembled state. In the waiting state, the connecting member 4 is located on the linkage rod 1 and the transmission rod 3 is disengaged from the connecting member 4; when the waiting state is switched to the assembled state, the connecting member 4 slides toward the transmission rod 3 along the length direction of the linkage rod 1; in the assembled state, the connecting member 4 spans the interval between the transmission rod 3 and the linkage rod 1, and is connected to the transmission rod 3 and the linkage rod 1.

[0033] In this solution, the two ends of the original traditional transmission rod 3 are cut off, so that the two short transmission rods 3 at the ends are always inserted on the column 2 as the end transmission rods 3. When the lifting table is installed, it is only necessary to connect the linkage rod 1 as the middle transmission rod 3 with the two transmission rods 3 as the end transmission rods 3; and the linkage rod 1 and the transmission rod 3 are connected by a slidable connecting member 4, so the connection between the linkage rod 1 and the transmission rod 3 can be directly achieved by sliding the connecting member 4, and the transmission connection between the two can also be achieved, and the installation is fast and simple; in this solution, the transmission rod 3 located on the column 2 does not require too much packaging of the column 2, nor will it have an adverse effect on the occupied space. Even when the transmission rod 3 does not protrude from the column 2, the existence of the transmission rod 3 will not affect the packaging and transportation of the column 2. The corresponding length of the linkage rod 1 is shorter than that of the traditional transmission rod 3, and the packaging and transportation cost can also be reduced.

[0034] like Figure 1-5 As shown, the structure is applied in a lifting table, which includes a table top 5, a crossbeam 6, a motor 7 and the above structure. The crossbeam 6 is installed on the lower surface of the table top 5 along the left-right direction, and the crossbeam 6 includes two spaced surrounding plates 8, and the motor 7 is arranged between the two surrounding plates 8. The linkage rod 1 is arranged in the surrounding plates 8 along the length direction of the crossbeam 6, and both ends of the linkage rod 1 pass through the surrounding plates 8; a receiving space 9 for installing a column 2 is formed on the crossbeam 6, and a cross bar 10 connected to the column 2 is provided on the front and rear sides of the receiving space 9; the upper end of the column 2 is provided with two flange portions 11 extending horizontally along the front and rear directions respectively, and after the upper end of the column 2 enters the receiving space 9, the flange portion 11 is abutted against the lower surface of the cross bar 10, and the flange portion is connected to the cross bar 10 by screws; at this time, the transmission rod 3 and the linkage rod 1 are coaxial and spaced.

[0035] The transmission rod 3 is arranged on the column 2, and can be protruded from the column 2 toward the direction of the linkage rod 1, or can be located inside the column 2; when the transmission rod 3 is located inside the column 2, the connecting member 4 can be connected to the transmission rod 3 inside the column 2 through the avoidance hole opened on the column 2. Although this does not increase the packaging and transportation cost of the column 2, it is not conducive to the connection of the connecting member 4 and the locking of the adjustable fastener 15 on the connecting member 4 on the transmission rod 3; Figure 5 , 9 As shown, in the present embodiment, the transmission rod 3 protrudes from the column 2 toward the linkage rod 1, which facilitates the connection member 4 to slide onto the transmission rod 3 and also facilitates the locking of the adjustable fastener 15 on the connection member 4; and the length of the transmission rod 3 protruding from the surface of the column 2 is in the range of 40-46 mm. In the present embodiment, the length of the transmission rod 3 protruding from the surface of the column 2 is 45 mm; the length of the transmission rod 3 is very short compared to the linkage rod 1. When the transmission rod 3 is at a shorter length, the packaging and transportation cost of the column 2 can also be maintained at a basically unchanged level.

[0036] Furthermore, if Figure 8 As shown, the length of the connecting member 4 is 80-85 mm. In this embodiment, the length of the connecting member 4 is 84 mm. The connecting member 4 has a sufficient length to ensure stable connection with the linkage rod 1 and the transmission rod 3.

[0037] like Figure 2 , 6 -9, both ends of the linkage rod 1 are provided with a first alignment convex portion 12, and the connector 4 is correspondingly provided with an alignment groove 13, the connector 4 is a set of pipe fittings, and the alignment groove 13 is arranged on the inner wall of the connector 4; the first alignment convex portion 12 is located in the alignment groove 13 and the first alignment convex portion 12 and the alignment groove 13 are slidably matched; the end of the transmission rod 3 facing the linkage rod 1 is provided with a second alignment convex portion 14, and in the assembled state, the alignment groove 13 and the first alignment convex portion 12 and the second alignment convex portion 14 are both snap-fitted; through the snap-fitting of the first alignment convex portion 12 and the alignment groove 13 and the snap-fitting of the second alignment convex portion 14 and the alignment groove 13, the transmission rod 3 and the linkage rod 1 are connected through the connector 4, and the synchronous lifting and lowering of the columns 2 on both sides can be realized. In this embodiment, the alignment convex portion is a spline, and the alignment groove 13 is a spline groove.

[0038] The connector 4 is provided with an adjustable fastener 15. In the ready-to-install state, the adjustable fastener 15 is loosened, and the connector 4 and the linkage rod 1 can slide relative to each other; in the assembled state, the adjustable fastener 15 is locked, and the connector 4 is locked with the linkage rod 1 and the transmission rod 3 respectively. The adjustable fastener 15 is used to control the selective sliding of the connector 4. When the adjustable fastener 15 is loosened, the connector 4 can slide. When the adjustable fastener 15 is locked, the connector 4 can be locked with the linkage rod 1 and the transmission rod 3 respectively, so as to maintain the assembled state. In this embodiment, the adjustable fastener 15 is two screws arranged at intervals to respectively lock the connector 4 with the linkage rod 1 and the connector 4 with the transmission rod 3.
