[0008] End limit blocks are arranged on the opposite sides of the instrument housing near the two ends of the fixing frame. The end limit blocks are arranged on the fixing frame and can resist and block the movement of the instrument housing.

[0009] Different from the method of directly opening holes for fixing, the device can be arranged and fixed on the fixing frame by plugging, so when in use, it is only necessary to fix the fixing frame in the fixing manner, and the above fixing method is more convenient when disassembling and assembling the multi-function instrument.

[0010] The structure of the fixing frame is that the cross section of the fixing frame is U-shaped, and the two ends are bent to a side away from the center. The bending can limit the meter housing to prevent it from leaving the preset position.

[0011] As a preferred solution, the instrument housing can only move along the length direction of the fixing frame, so it is only necessary to provide a limiting structure in the length direction of the fixing frame to prevent the instrument housing from being separated.

[0012] As a preferred solution, the instrument housing is provided with mounting grooves and limiting grooves along the length direction, so that it can be arranged along the length direction to avoid taking up more space.

[0013] The fixing frame is fixed in such a way that the fixing frame is penetrated by screws and connected to the reference plane.

[0030] like Figure 1-3 A multifunctional instrument assembly connection structure is shown, the multifunctional instrument includes an instrument housing 5, which is different from the existing housing structure. The instrument housing 5 is provided with a mounting groove 51 and a limiting groove 52 along the same direction. Different from the method of setting holes and fixing by screws, the above-mentioned slots can be used for plugging and fixing, and as shown Figure 2 As shown, as a preferred solution, the instrument housing 5 is provided with a mounting groove 51 and a limiting groove 52 along the length direction. They can be arranged along the length direction to avoid taking up more space. Therefore, after plugging, the length direction of the multifunctional instrument can be parallel to the length direction of the fixing frame 1, that is, after positioning the length direction of the fixing frame 1, the direction of the multifunctional instrument can be positioned.

[0031] Afterwards, in order to fix, the installation groove 51 can be penetrated by the fixing frame 1 set on the reference plane. When in use, it is only necessary to fix the fixing frame 1 on the reference plane, and then other subsequent structures can be fixed relatively to it, and the method is plug-in, and no additional hole opening connection is required, so the subsequent connection operation will be more convenient, and for positioning, the fixing frame 1 is provided with a plurality of guide limit blocks 2 that can penetrate the limit groove 52 along the length direction. While positioning, the guide limit block 2 can also move perpendicularly to the structure to which it is plugged and in the length direction, which can effectively improve the strength of the fixed structure. Since the single fixing frame 1 is fixed with a bending structure, it is easy to deform after being subjected to greater pressure. After the guide limit block 2 is provided, its lateral pressure bearing capacity can be increased without affecting its fixation.

[0032] like Figure 1 As shown, it should be noted that a single fixing frame 1 can be penetrated by multiple instrument housings 5, so any number of multi-function instruments can be set according to needs, as long as the length of the fixing frame 1 as a whole is not exceeded, and in the above structure, a wiring block 6 can be set between adjacent instrument housings 5, and the wiring block 6 can also be penetrated by the fixing frame 1 and the guide limit block 2 to complete the positioning and plugging, and can be used in conjunction with the multi-function instrument, and multiple wiring blocks 6 can be set between the instrument housings 5, and the wiring blocks 6 are provided with wiring terminals at both ends perpendicular to the length direction of the fixing frame 1. Accordingly, as a preferred embodiment, the wiring terminals of the multi-function instrument are located on both sides of the length direction of the fixing frame 1, so as shown in the figure, Figure 1 As shown, all the wiring terminals are symmetrically arranged on both sides of the length direction of the fixing frame 1, so it is convenient to carry out wiring.

[0033] Finally, the most important step is to fix the multi-function instrument, such as Figure 1 As shown, end limit blocks 3 are provided on the opposite sides of the instrument housing 5 near the two ends of the fixing frame 1. The end limit blocks 3 are provided on the fixing frame 1 and can resist and block the movement of the instrument housing 5. By providing two end limit blocks 3, the fixation of all the instrument housings 5 ​​and the wiring blocks 6 can be completed, and only one end limit block 3 needs to be removed to complete the disassembly of all the above structures. Therefore, maintenance is more convenient, and there is no need to remove many screws, and there is no need to install many screws during installation.

[0034] And if Figure 5 , 6, the structure of the end stopper 3 is that the end stopper 3 includes a long strip and a semicircular section. The long strip has the same width as the guide stopper 2, and the semicircular section is larger than the guide stopper 2 and the vertical surface is perpendicular to the length direction of the fixing frame 1. The semicircular section is used to limit the position, while the long strip facilitates the fixation of the structure. After the long strip of the end stopper 3 is inserted into the limit groove 52, it moves until the semicircular section contacts the instrument housing 5. When they contact, the fixation operation is completed.

[0035] Therefore, it can be seen from the above structure that, unlike the direct hole-opening fixing method, the present device can be arranged and fixed on the fixing frame 1 by plugging, so when in use, it is only necessary to fix the fixing frame 1 in a fixed manner, and the above fixing method is more convenient when disassembling and assembling the multi-function instrument.

[0036] As another embodiment, in order to facilitate changing the position of the limit block, the opening of the fixing frame 1 for setting the screw 4 is a waist-shaped hole, and the length direction is parallel to the length direction of the fixing frame 1. In addition, the waist-shaped hole is provided to facilitate the fixing of the fixing frame 1 relative to the reference plane. When opening the hole, it is inevitable that the position of the opening is inaccurate. By providing the waist-shaped hole, the fixing frame 1 can be installed normally after the opening is offset, thereby reducing the difficulty of installation.

[0037] Furthermore, in the above structure, the fixing frame 1 is fixed in such a manner that the fixing frame 1 is penetrated by screws 4 and connected to the reference plane. At the same time, the fixing block is fixed in such a manner that the guide limit block 2 and the end limit block 3 are both connected to the fixing frame 1 by screws 4. That is to say, when the screws are fixing the fixing frame 1, they are also required to cooperate to complete the fixing of the guide limit block 2 or the end limit block 3. The more the guide limit blocks 2 are set, the stronger the lateral pressure bearing capacity of the structure. The end limit block 3 must be set due to structural necessity. Therefore, if it can be completed by a single screw 4, there is no need to set additional screws to avoid increasing the difficulty of installation.

[0038] like Figure 5 , 6 As shown, as an embodiment, the structure of the fixing frame 1 is that the cross section of the fixing frame 1 is U-shaped, and the two ends are bent to one side away from the center. The bending can limit the meter housing 5 to prevent it from being out of the preset position. In addition to the length direction, it can cooperate with the installation groove 51 to achieve limitation in other directions, thereby preventing the meter housing 5 from being out of the working position.

[0039] That is to say, in order to facilitate the fixing of the structure, as a preferred solution, the meter housing 5 can only move along the length direction of the fixing frame 1. Therefore, it is only necessary to set a limiting structure in the length direction of the fixing frame 1 to prevent the meter housing 5 from being separated.
