【detailed description】

The technical solutions of the embodiments of the present invention will be explained and described below in conjunction with the accompanying drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention, not all of them. Based on the examples in the implementation manners, other examples obtained by those skilled in the art without creative work shall fall within the protection scope of the present invention.

In the following description, the terms "inner", "outer", "upper", "lower", "left", "right", etc., appearing to indicate orientation or positional relationships are only for the convenience of describing the embodiments and simplifying the description. It does not indicate or imply that the pointed device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention.

Example one:

As shown in Figures 1 to 6, this embodiment shows a quick assembling structure for the control box 2 of a lifting table, which includes a beam 1 and a control box 2. The beam 1 is used to be installed under the table board 3, and the beam 1 is provided with a accommodating groove 101 for accommodating the control box 2. The inner side wall of the accommodating groove 101 and the corresponding outer side wall of the control box 2 are provided with a sliding rail groove 102 and the other A positioning protrusion 21 is provided on the upper part. In an assembled state, the positioning protrusion 21 is clamped into the sliding rail groove 102, and the sliding rail groove 102 allows the positioning protrusion 21 to slide laterally therein.

In this embodiment, on the inner wall of the accommodating groove 101 and the outer side wall of the control box 2, one of them is provided with a positioning protrusion 21, and the other is provided with a slide rail groove 102. When assembling, the positioning protrusion 21 is clamped to the slide In the rail groove 102, such a structural design does not require major changes to the existing beam 1 or the control box 2, and the cost is better controlled. At the same time, some customized products are reduced, which can make the products more generalized.

Secondly, in the present invention, since the positioning protrusion 21 can slide laterally in the slide rail groove 102, the installation position of the entire control box 2 can be adjusted, and can be adjusted in the lateral direction along the beam 1, so that the control Box 2 can be set at any position in the horizontal direction. This is very important because different customers may use different lifting columns and different wiring methods. This makes the position of control box 2 may also need to be changed, such as 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 troublesome to change the position. In the present invention, even the terminal user can easily perform the installation position of the control box 2 adjust.

In addition, from the perspective of ease of assembly, this structure is more convenient to assemble, because the position of the control box 2 can be adjusted. During assembly, the control box 2 can be clamped in many positions of the beam 1, not limited to specific For the assembly user, it is more random for the assembly user to install the card in the position. You only need to consider the clamping first, and then adjust the position later, and the installation is very convenient.

In order to better control costs and minimize changes, in this embodiment, it is preferable that the sliding rail groove 102 is provided on the inner side wall of the accommodating groove 101, and the positioning protrusion 21 is provided on the control box 2. On the outer side wall, beam 1 is usually a metal frame, and it is relatively easy to set grooves, while control box 2 is usually an injection molded product. It is not difficult to set up a convex structure. At the same time, because the length of beam 1 is relatively long, the length of control box 2 is relatively long. The length is smaller than the beam 1, so 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 provided on the control box 2, the sliding The distance is relatively limited.

It should be noted that in other embodiments, the slide rail groove 102 is not limited to be provided on the beam 1. If there is no need for a long sliding distance during actual installation, the slide rail groove 102 may also be provided in the control On the box 2, this embodiment also falls within the protection scope of the present invention.

In order to prevent the control box 2 from being easily slid due to external force after the control box 2 is assembled with the beam 1, a certain resistance is provided to the sliding of the control box 2 in this embodiment, that is, after the control box 2 and the beam 1 are assembled, the The positioning protrusion 21 is in an interference fit with the sliding rail groove 102 or the outer side wall of the control box 2 is in an interference fit with the inner side wall of the accommodating groove 101. In this embodiment, it is preferable to have an interference fit between the positioning protrusion 21 and the sliding rail groove 102. Through the interference fit, there is a certain resistance between the sliding rail groove 102 and the positioning protrusion 21, so that the user needs to adjust the control box. When the position is 2, a certain external force is required to move. Of course, in other embodiments, interference may be generated between the entire outer side wall of the control box 2 and the inner side wall of the beam 1, and the resistance effect can also be achieved.

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

There can be 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 side wall of the control box 2. 2 is one body. This one-piece type does not require additional assembly of positioning protrusions 21, and at the same time uses a certain elastic deformation force of the elastic buckle itself to achieve clamping. In order to allow the elastic buckle to retract better, the control box 2 An escape groove 22 for the elastic buckle to retract is provided on the outer wall. Of course, in other embodiments, the avoiding slot 22 is not necessary and can be omitted.

In other embodiments, the positioning protrusion 21 may also be a separate component, which is movably mounted on the outer side wall of the control box 2. For example, the positioning protrusion 21 may be a movable pin which can be relative to the control box. 2 The outer wall is telescopic, and there is a return spring between the movable pin and the control box 2, of course, it can also be other movable parts. The advantage of this movable positioning protrusion 21 is that it is not easy to be damaged during assembly and disassembly.

Regarding the structure of the cross beam 1, the cross beam 1 in this embodiment includes two cross bars 10 arranged in parallel and spaced apart. The cross bars 10 can be made of rectangular metal profiles. The space between the two cross bars 10 forms the accommodation. Groove 101, in order to increase the stability of assembly, the two opposite outer side walls of the control box 2 are provided with the positioning protrusions 21, and at the same time the two corresponding accommodating grooves 101 are also provided on the two corresponding inner side walls. There is a sliding rail slot 102.

In order to further reduce the cost of modification, the slide rail groove 102 in this embodiment is very cleverly designed, as shown in Fig. 5 and Fig. 6 for details. For the cross bar 10, the edges of the metal profile are usually chamfered. It is precisely because of the existence of these arc chamfers 103 that when the cross bar 10 is installed on the table board 3, a sliding rail groove 102 is formed between the arc chamfer 103 and the table board 3. Based on this 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. And more importantly, the existence of this arc chamfer 103 is also conducive to the user's disassembly and assembly, because when the user needs to disassemble the control box 2, when the external force acts on the control box 2, the positioning protrusion 21 will be in contact with the circle. The arc chamfer 103 makes contact, so that the arc chamfer 103 will generate a guiding force on the positioning protrusion 21, and guide the positioning protrusion 21 to shrink, that is, when disassembling, the surface of the arc chamfer 103 forms the positioning protrusion 21 The first guide surface. Therefore, in this embodiment, there is no need to improve the existing beam 1 or the beam 10, and only by using the arc chamfer 103 on the existing beam 10, the slide rail groove 102 for positioning is naturally formed, and at the same time, it can be used for positioning. It has a guiding effect during disassembly and assembly, achieving multiple functions with the lowest cost, and the economic value is very high.

In order to further save effort during disassembly and assembly, the positioning protrusion 21 is provided with a second guide surface 211 for guiding the positioning protrusion 21 to escape from the slide rail groove 102, and the second guide surface 211 faces the cross bar 10 The arc is chamfered on the 103 side.

Regarding the structure of the control box 2 itself, because 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, both of which are designed as separate bodies. Because the upper box body 201 will be empty Cavity, so the wall thickness is generally not very thick, so the positioning protrusion 21 is preferably provided on the side wall of the bottom cover 202, the bottom cover 202 is a relatively integrated part, and is installed on the bottom cover 202 , There is no need to change the upper box body 201, and the position is relatively compatible with the position of the arc chamfer 103, so the design on the bottom cover 202 is very suitable.

Embodiment two:

As shown in FIG. 7, the difference between this embodiment and the first embodiment is mainly in the design of the slide rail groove 102. The first embodiment is a more preferable solution, which can make the cost control very low, while in this embodiment The slide rail groove 102 is an independently designed strip groove. The main purpose of this design is to have better stability of the slide rail groove 102, because it is similar to the arc chamfer 103 in the first embodiment, and its size is more Limited, if the arc chamfer 103 is small, the depth of the slide rail groove 102 is relatively small. Therefore, the slide rail groove 102 in the first embodiment is relatively limited by the size of the arc chamfer 103 itself.

In this embodiment, the slide rail groove 102 is an independent strip-shaped groove, and its size may not be limited to the arc chamfer 103. The cost is higher than that of the first embodiment, but the stability is better. The design of the guide surface during disassembly and assembly, the third guide surface 104 is provided at the end of the strip groove in this embodiment, and the positioning protrusion 21 preferably adopts a movable pin structure. When disassembly and assembly are required, the control box 2 Move to the end of the strip-shaped groove to allow the movable pin to interfere with the third guide surface 104, so that the movable pin is retracted, so that the control box 2 can be slowly separated from the slide rail groove 102 to complete the control box 2 Disassembly.

Embodiment three:

This embodiment is an elevating table frame, including a beam, lifting columns installed on both sides of the beam, a control box installed in the beam, the control box controls the lifting of the lifting column, and the control box and the beam are as Embodiment 1 or Embodiment 2 or its equivalent quick assembly structure.

The above are only specific embodiments of the present invention, but the scope of protection 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 drawings and the description in the above specific embodiments. content.
