Description

[Technical field]

[0001] The invention relates to a lifting table control box quick assembly structure and a lifting table frame, belonging to the field of lifting table accessories. [Background technology]

[0002] Tables are daily furniture widely used by people in work, study and life. There are many types of existing tables, such as computer tables, study tables, office desks, etc. As people's quality of life continues to improve, the requirements for the comfort and convenience of tables are also getting higher and higher. Therefore, in order to meet the requirements of users of different heights, a height-adjustable lifting table has appeared on the market. In order to make it more convenient for people to operate, the lifting table in the existing technology has added an electric lifting function, that is, an electric lifting table.

[0003] The basic structure of the current electric lift table includes a table top, a crossbeam is arranged under the table top, and lifting columns are arranged on both sides of the table top. Usually, a control box is arranged in the crossbeam, and the control box is used to control the lifting columns. There are many ways to install the control box. The most common one is to set a hole on the control box and fix it to the table top with fasteners such as screws. Of course, there are similar plug-in structures. For example, the Chinese utility model patent CN205030005U discloses a controller installation structure, which adopts the plug-in between the control box and the crossbeam to achieve installation.

[0004] The current control box installation structure, if it is a screw fastener method, is more troublesome to assemble, requires the help of tools to achieve, and is also more laborious. If it is a plug-in method, although no tools are required, the crossbeam and the control box itself will change greatly in structure, and the investment cost is high. At the same time, there is also a problem with both methods, that is, the installation position of the control box itself is relatively fixed, and it is troublesome to change the position of the control box if it needs to be replaced. [Summary of the invention]

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a lifting table control box quick assembly structure and a lifting table frame, so that the assembly of the control box is more convenient and the cost is lower.

[0006] To solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A quick assembly structure for a control box of a lifting table comprises a crossbeam and a control box. The crossbeam is used to be installed under a table top. A receiving groove for receiving the control box is provided in the crossbeam. One of the inner wall of the receiving groove and the outer wall of the control box is provided with a slide rail groove, and the other is provided with a positioning protrusion. In the assembled state, the positioning protrusion is snapped into the slide rail groove, and the slide rail groove allows the positioning protrusion to slide horizontally therein.

[0008] The beneficial effects of the present invention are as follows:

[0009] In the present invention, a positioning protrusion is provided on one of the inner wall of the accommodating groove and the outer wall of the control box, and a slide rail groove is provided on the other. During assembly, the positioning protrusion is snapped into the slide rail groove. Such a structural design does not require major changes to the existing beam or control box, reduces some customized products, and can make the product more universal.

[0010] Secondly, in the present invention, since the positioning protrusion can slide laterally in the slide rail groove, it is equivalent to that the installation position of the entire control box can be adjusted, and can be adjusted in the horizontal direction along the crossbeam, so that the control box can be set at any horizontal position. This is very important, because different customers may use different lifting columns and different wiring methods, which may also require the position of the control box to change. For example, in the traditional installation method, the installation position of the control box is relatively fixed. Even if it can be disassembled and replaced, it is relatively troublesome to change the position. In the present invention, even the terminal user can easily adjust the installation position of the control box.

[0011] In addition, from the perspective of assembly convenience, such a structure is easier to assemble because the position of the control box can be adjusted. During assembly, the control box can be installed at many positions of the beam, and is not limited to installation at a specific position. For the assembling user, it is more casual and only needs to consider tightening first and then adjust the position later. The installation is very convenient.

[0012] Preferably, the slide rail groove is arranged on the inner wall of the accommodating groove, and the positioning protrusion is arranged on the outer side wall of the control box.

[0013] Preferably, after the control box is assembled with the crossbeam, the positioning protrusion and the slide rail groove are in interference fit or the outer wall of the control box and the inner wall of the accommodating groove are in interference fit.

[0014] Preferably, the positioning protrusion is an elastic clip arranged on the outer wall of the control box, and the outer wall of the control box is provided with an avoidance groove for the elastic clip to retract; or, the positioning protrusion is movably mounted on the outer wall of the control box, and the control box is also provided with a reset member for resetting the positioning protrusion.

[0015] Preferably, the crossbeam comprises two cross bars which are arranged in parallel and at intervals, the accommodation groove is formed between the two cross bars, and the positioning protrusions are provided on two opposite outer side walls of the control box.

[0016] Preferably, the edge of the beam facing the table top is provided with an arc chamfer. When the beam is installed under the table top, a slide rail groove is formed between the arc chamfer and the table top. During disassembly and assembly, the arc chamfer surface forms a first guide surface for the positioning protrusion.

[0017] Preferably, the positioning protrusion is provided with a second guiding surface for guiding the positioning protrusion to disengage from the slide rail groove.

[0018] Preferably, the slide rail groove is a strip-shaped groove independently provided on the inner wall of the accommodating groove.

[0019] Preferably, the control box comprises an upper box body and a bottom cover, and the positioning protrusion is arranged on the side wall of the bottom cover.

[0020] The present invention also discloses a lifting table frame, comprising a crossbeam, lifting columns installed on both sides of the crossbeam, and a control box installed in the crossbeam, wherein the control box controls the lifting of the lifting columns, and is characterized in that the quick assembly structure described in any of the above schemes is adopted between the control box and the crossbeam.

[0021] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings.

[0030] The technical solutions of the embodiments of the present invention are explained and described below in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0031] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the referred device or element must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limitations on the present invention.

[0032] Embodiment 1:

[0033] like Figures 1 to 6 As shown, this embodiment shows a quick assembly structure of a lifting table control box 2, including a crossbeam 1 and a control box 2, the crossbeam 1 is used to be installed under the table top 3, and a receiving groove 101 for receiving the control box 2 is provided in the crossbeam 1, and one of the inner side wall of the receiving groove 101 and the outer side wall corresponding to the control box 2 is provided with a slide rail groove 102, and the other is provided with a positioning protrusion 21, in the assembled state, the positioning protrusion 21 is clamped into the slide rail groove 102, and the slide rail groove 102 allows the positioning protrusion 21 to slide horizontally therein.

[0034] In this embodiment, a positioning protrusion 21 is provided on one of the inner wall of the accommodating groove 101 and the outer wall of the control box 2, and a slide rail groove 102 is provided on the other. During assembly, the positioning protrusion 21 is snapped into the slide rail groove 102. Such a structural design does not require major changes to the existing beam 1 or the control box 2, and has better cost control. At the same time, it reduces some customized products, making the products more universal.

[0035] Secondly, in the present invention, since the positioning protrusion 21 can slide laterally in the slide rail groove 102, it is equivalent to that the installation position of the entire control box 2 can be adjusted, and can be adjusted in the horizontal direction along the beam 1, so that the control box 2 can be set at any horizontal position. This is very important, because different customers may use different lifting columns and different wiring methods, which may also require the position of the control box 2 to change. For example, in the traditional installation method, the installation position of the control box 2 is relatively fixed. Even if it can be disassembled and replaced, it is relatively troublesome to change the position. In the present invention, even the terminal user can easily adjust the installation position of the control box 2.

[0036] In addition, from the perspective of assembly convenience, such a structure is more convenient to assemble because the position of the control box 2 is adjustable. During assembly, the control box 2 can be installed at many positions of the beam 1 and is not limited to being installed at a specific position. For the assembling user, it is more casual and only needs to consider tightening first and then adjust the position. The installation is very convenient.

[0037] In order to better control costs and minimize changes, in this embodiment, it is preferred to arrange the slide rail groove 102 on the inner wall of the accommodating groove 101, and the positioning protrusion 21 is arranged on the outer wall of the control box 2. Usually, the beam 1 is a metal frame, and it is relatively easy to arrange the groove, and the control box 2 is usually an injection molded product, and it is not difficult to arrange the protrusion structure. At the same time, because the length of the beam 1 is relatively long, and the length of the control box 2 is smaller than the beam 1, the slide rail groove 102 is arranged on the beam 1, which helps to increase the sliding distance between the control box 2 and the beam 1. If the slide rail groove 102 is arranged on the control box 2, the sliding distance is relatively limited.

[0038] It should be noted that in other embodiments, the slide rail groove 102 is not limited to being set on the beam 1. If a longer sliding distance is not required during actual installation, the slide rail groove 102 can also be set on the control box 2. This embodiment also falls within the protection scope of the present invention.

[0039] In order to prevent the control box 2 from sliding easily due to external force after being assembled with the crossbeam 1, a certain resistance is set for the sliding of the control box 2 in this embodiment, that is, after the control box 2 is assembled with the crossbeam 1, the positioning protrusion 21 and the slide rail groove 102 are interference fit or the outer wall of the control box 2 and the inner wall of the accommodating groove 101 are interference fit. In this embodiment, it is preferred that the positioning protrusion 21 and the slide rail groove 102 are interference fit, and the interference fit can make a certain resistance between the slide rail groove 102 and the positioning protrusion 21, so that when the user needs to adjust the position of the control box 2, a certain external force is required to move it. Of course, in other embodiments, the entire outer wall of the control box 2 and the inner wall of the crossbeam 1 may also be interference fit, which can also achieve a resistance effect.

[0040] It should be noted that the matching relationship between the positioning protrusion 21 and the slide rail groove 102 in the present invention is not limited to interference fit. In other embodiments, the positioning protrusion 21 and the slide rail groove 102 can also be a clearance fit, that is, the positioning protrusion 21 can slide relatively freely in the slide rail groove 102, similar to hanging the control box 2 in the slide rail groove 102. This embodiment also falls within the protection scope of the present invention.

[0041] There are multiple embodiments for the specific structure of the positioning protrusion 21. In this embodiment, in order to simplify the structure, the positioning protrusion 21 is an elastic buckle provided on the outer wall of the control box 2. The elastic buckle is integrated with the control box 2. This integrated type does not require additional assembly of the positioning protrusion 21. At the same time, the elastic deformation force of the elastic buckle itself is used to achieve the clamping. In order to allow the elastic buckle to retract better, an avoidance groove 22 for the elastic buckle to retract is provided on the outer wall of the control box 2. Of course, in other embodiments, the avoidance groove 22 is not necessary and can be omitted.

[0042] In other embodiments, the positioning protrusion 21 may also be a separate component, which is movably mounted on the outer wall of the control box 2. For example, the positioning protrusion 21 may be a movable pin, which can be extended and retracted relative to the outer wall of the control box 2. At the same time, there is a return spring between the movable pin and the control box 2. Of course, it can also be other movable components. The advantage of this movable positioning protrusion 21 is that it is not easily damaged during assembly and disassembly.

[0043] Regarding the structure of the crossbeam 1, the crossbeam 1 in this embodiment includes two cross bars 10 arranged in parallel and at intervals. The cross bar 10 can be composed of a rectangular metal profile. The space between the two cross bars 10 forms the accommodating groove 101. In order to increase the stability of assembly, the two relative outer walls of the control box 2 are provided with the positioning protrusions 21, and the two corresponding inner walls of the corresponding accommodating groove 101 are also provided with slide rail grooves 102.

[0044] In order to further reduce the modification cost, the slide rail groove 102 in this embodiment is very cleverly designed. Figure 5 and Figure 6 As shown, for the crossbar 10, the edges of the metal profiles are usually chamfered. It is precisely because of the existence of these arc chamfers 103 that when the crossbar 10 is installed on the table top 3, a slide rail groove 102 is formed between the arc chamfer 103 and the table top 3. Based on such a structure, for this embodiment, there is no need to improve the existing crossbar 10, and only the existing structure can be used, and the cost is very low. More importantly, the existence of this arc chamfer 103 is also conducive to user disassembly and assembly, because when the user needs to disassemble the control box 2, when external force acts on the control box 2, the positioning protrusion 21 will contact the arc chamfer 103, so that the arc chamfer 103 will generate a guiding force on the positioning protrusion 21, guiding the positioning protrusion 21 to shrink, that is, during disassembly and assembly, the surface of the arc chamfer 103 forms a first guiding surface for the positioning protrusion 21. Therefore, in this embodiment, there is no need to improve the existing crossbeam 1 or crossbar 10. The positioning slide rail groove 102 is naturally formed by using the arc chamfer 103 on the existing crossbar 10. At the same time, it can also provide guidance during disassembly and assembly, achieving multiple functions at the lowest cost, and the economic value is very high.

[0045] In order to further save effort during assembly and disassembly, the positioning protrusion 21 is provided with a second guide surface 211 for guiding the positioning protrusion 21 to disengage from the slide rail groove 102 , and the second guide surface 211 faces the arc chamfer 103 of the cross bar 10 .

[0046] As for the structure of the control box 2 itself, since some electrical components need to be installed inside the control box 2, the control box 2 itself includes an upper box body 201 and a bottom cover 202, which are designed separately. Since the upper box body 201 has a cavity, the wall thickness is generally not very thick, so the positioning protrusion 21 is preferably arranged on the side wall of the bottom cover 202. The bottom cover 202 is a relatively integrated component, and after being arranged on the bottom cover 202, there is no need to change the upper box body 201, and the position is relatively consistent with the position of the arc chamfer 103, so it is very suitable to design it on the bottom cover 202.

[0047] Embodiment 2:

[0048] like Figure 7 As shown, the difference between this embodiment and embodiment one mainly lies in the different designs of the slide rail groove 102. Embodiment one is a more preferred solution, which can keep the cost very low, while the slide rail groove 102 in this embodiment is an independently designed strip groove. The main purpose of such a design is to provide better stability for the slide rail groove 102. Because it is similar to the circular chamfer 103 in embodiment one, its size is relatively limited. If the circular chamfer 103 is smaller, the depth of the slide rail groove 102 is also relatively small. Therefore, the slide rail groove 102 in embodiment one is relatively limited by the size of the circular chamfer 103 itself.

[0049] In the present embodiment, the slide rail groove 102 is an independent strip groove, and its size is not limited by the arc chamfer 103. The cost is higher than that of the first embodiment, but the stability is better. At the same time, for the guide surface design during disassembly and assembly, a third guide surface 104 is set at the end position of the strip groove in the present embodiment, and the positioning protrusion 21 preferably adopts a movable pin structure. When disassembly and assembly are required, the control box 2 is moved to the end of the strip groove, and the movable pin is allowed to contact with the third guide surface 104, so that the movable pin is retracted, so that the control box 2 can slowly detach from the slide rail groove 102 to complete the disassembly of the control box 2.

[0050] Embodiment three:

[0051] The present embodiment is a lifting table frame, including a crossbeam, lifting columns installed on both sides of the crossbeam, and a control box installed in the crossbeam. The control box controls the lifting of the lifting columns. The control box and the crossbeam adopt a quick assembly structure as in Embodiment 1 or Embodiment 2 or an equivalent thereof.

[0052] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the present invention will be included in the scope of the claims.
