[0045] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0046] Example: See Figures 1 to 18 As shown, a fixed connection structure comprises:

[0047] At least one connecting block 1, with at least one clamping member 2 provided on its side end surface;

[0048] At least one fixing block 3, wherein at least one clamping groove 4 is provided on the fixing block 3;

[0049] The fixing block 3 is connected to the connecting block 1 by means of the clamping groove 4 and the clamping member 2.

[0050] In this embodiment, a connecting block and two fixing blocks are included, and a clamping piece is provided at each end of the connecting block, and a clamping groove is provided on the fixing block. One side of the connecting block is clamped with a fixing block, or both sides of the connecting block are clamped with the fixing blocks, which can be selected and installed according to actual conditions.

[0051] A connecting part is also provided, and the connecting part is arranged on the clamping part and / or the fixing block, and the connecting part makes the clamping part and the clamping groove tightly fit and connected. The connecting part can be arranged only on the clamping part, or only on the fixing block, or respectively on the clamping part and the fixing block.

[0052] In one embodiment, see Figure 1 , 2 As shown, the connecting portion includes two gaps 5 .

[0053] The two gaps 5 are arranged at intervals on the clamping member 2, and the two gaps 5 separate the clamping member 2 into a middle member 6 and a first clamping portion 7 and a second clamping portion 8 respectively arranged on both sides of the middle member 6. The outer surfaces of the first clamping portion 7 and the second clamping portion 8 are tightly matched with the inner walls on the opposite sides of the clamping groove 4, respectively, and the inner ends of the middle member, the first clamping portion and the second clamping portion are fixedly connected to the end of the connecting block.

[0054] Among them, the distance between the outer side surface of the first connecting part and the outer surface of the second clamping part will be greater than the length of the clamping groove. In this way, when clamping, the first clamping part and the second clamping part will be compressed inward, so that the first clamping part approaches the middle part and elastically deforms, and the second clamping part approaches the middle part and elastically deforms. In this way, the distance between the outer side surface of the first clamping part and the outer side surface of the second clamping part will match the length of the clamping groove, and the first clamping part and the second clamping part have a deformation force that recovers outward, so that the clamping part and the clamping groove are tightly fitted and connected through their elastic recovery force.

[0055] In the present invention, there are two types of snap-in slots. In the first type, the snap-in slot is arranged in the middle of the fixing block, and the snap-in slot is a square slot.

[0056] The two ends of the square groove are arc-shaped surfaces respectively, and the arc-shaped surfaces at both sides are respectively against the outer surfaces of the two sides of the clamping member.

[0057] The end of the clamping groove may be a flat surface or an arc surface.

[0058] The second mode: the clamping groove is arranged on the outer side wall of the fixing block.

[0059] There are two different forms, so they have different states after assembly, you can choose according to the actual situation.

[0060] See also Figures 3 to 6 As shown, in another preferred embodiment, on the basis of the two gaps on the clamping member 2, a protruding limiting end 9 is provided at the end of the first clamping portion 7 and the second clamping portion 8 away from the outer surface of the connecting block 1. The limiting end will be outside the fixed block, and the fixed block is between the connecting block and the limiting end. The movement of the fixed block is limited by the limiting end and the connecting block, and the fixed block is clamped by the first clamping portion and the second clamping portion so that it cannot shake.

[0061] See also Figure 7 , 8 As shown, in another preferred embodiment, the connecting portion includes two gaps, which are arranged on the clamping member, and no limiting end is arranged on the gaps.

[0062] Moreover, the connecting portion also includes two arc-shaped protrusions 10 arranged on the fixing block 3, the inner ends of the two arc-shaped protrusions 10 are respectively arranged on the inner walls on both sides of the opposite sides of the clamping groove 4, and the two arc-shaped protrusions 10 are respectively against the outer surface of the first clamping portion 7 and the outer surface of the second clamping portion 8.

[0063] The distance between the two arc-shaped protrusions will be smaller than the distance between the outer surface of the first clamping part and the outer surface of the second clamping part in the initial state. When the clamping part is inserted into the slot, the two arc-shaped protrusions squeeze the first clamping part and the second clamping part close to the middle part, squeezing it. In this way, the elastic restoring force of the first clamping part and the second clamping part plays a role of restoring the clamping connection, so that the connecting part and the slot are tightly fitted and connected.

[0064] See also Figures 9 to 12 As shown, in another preferred embodiment, the gap is not arranged on the connecting piece, and two of the gaps 5 are arranged on the fixing block 3, and the two gaps 5 are respectively arranged on the fixing blocks 3 on both sides of the snap-in groove 4, and a spring sheet 11 is formed between each of the gaps 5 and the side wall of the snap-in groove 4, and the spring sheet 11 is tightly fitted with the outer surface of the snap-in piece 2.

[0065] In the initial state, the distance between the two spring sheets will be smaller than the width of the snap-in piece. In this way, after the snap-in piece is inserted into the snap-in groove, it will squeeze the two spring sheets. The snap-in piece will be clamped by the restoring force of the spring sheets, thereby realizing a tight fit snap connection between the connecting block and the fixing block.

[0066] See also Fig. 9 , 10 As shown, the structure is that the clamping groove is arranged in the middle of the fixing block.

[0067] See also Fig.11 , 12 As shown, the structure in which the clamping groove is arranged on the outer side wall of the fixing block.

[0068] See also Fig.13 , 14 As shown, in another preferred embodiment, on the basis of two gaps being set on the fixed block, an arc-shaped protrusion 10 is provided on the inner surface of each of the elastic pieces 11, and the arc-shaped protrusion 10 is arranged in the clamping groove 4, and the inner surface of the arc-shaped protrusion 10 is against the outer surface of the clamping member 2.

[0069] By setting the arc-shaped convex part, the distance between the two spring sheets is further reduced, so that the two spring sheets can clamp the clamping member with greater force, and the clamping fit between the connecting block and the fixing block is tighter and more secure.

[0070] As another preferred embodiment, the connecting portion includes two arc-shaped protrusions 10;

[0071] See also Fig.15 , 16 As shown, the two arc-shaped protrusions 10 are arranged on the fixing block 3, and the inner ends of the two arc-shaped protrusions 10 are respectively arranged on the inner walls on both sides of the opposite sides of the clamping groove 4, and the two groups of the arc-shaped protrusions 10 are arranged opposite to each other, and the inner surfaces of the two arc-shaped protrusions 10 are respectively against the outer surfaces on both sides of the clamping member 2.

[0072] In this embodiment, no gap is provided, only an arc-shaped protrusion is provided, the arc-shaped protrusion is used to clamp the connector, and the elastic deformation of the connecting block and the fixing block themselves is used to achieve a tight fit and fixation between the connecting block and the fixing block.

[0073] See also Fig.17 , 18 As shown, in another preferred embodiment, on the basis of the arc-shaped convex parts on both sides of the clamping groove, in order to further improve the convenience of clamping the connection block and the fixed block, the connection part also includes a gap 5, and the gap is set in the middle of the clamping piece. In this way, the gap separates the clamping piece into two pieces, so that there is a deformation space between the two clamping pieces to approach each other. When the arc-shaped convex part squeezes the clamping piece, the two clamping pieces can approach each other, and the gap is used to elastically deform the clamping piece and the arc-shaped convex part is used to tightly fit the clamping limit, so as to ensure the stability and quality of the clamping.

[0074] Of course, in another preferred embodiment, the two arc-shaped protrusions are respectively arranged on the outer surfaces on both sides of the clamping member, and the outer surfaces of the two arc-shaped protrusions are respectively against the inner surfaces on the opposite sides of the clamping groove (not shown in the figure), that is, the arc-shaped protrusions are not arranged on the fixed block.
