[0042] With the development of various industrial grade, household grade electronic products, the continuity, long-term, stability of its work is required by various consumer markets, and the connection of many devices needs to be fixed for a long time or permanently to meet the daily life and work requirements; The current device connection line almost has no anti-loosening function, when the device connection line is accidentally touched by external force or is subjected to long-term vibration generated by device work, it is easy to fall off with the body connected with it, which leads to the device cannot work normally, and brings various troubles to life and work.

[0043] The utility model provides a kind of anti-loosening connection structure, for the first structure piece 5 and second structure piece 3 of being inserted are locked.

[0044] Please refer to Figure 5 、 Figure 6 、 Figure 8 As shown in the embodiment of the utility model, the anti-loosening connection structure includes elastic deformation part 2, and the elastic deformation part 2 is connected to the first structure piece 5, and the elastic deformation part 2 refers to the structure piece that extrusion or compression deformation itself when subjected to external force, including but not limited to plastic, silicone and other materials.

[0045] As Figure 6As shown in the drawings, the clamping space 31 is arranged in the second structural member 3, the side wall of the second structural member 3 is provided with a through hole 32 which is communicated with the clamping space 31 and the outside; in the axial direction of the through hole 32, the contour line of the elastic deformation part 2 projected on the first structural member 5 is at least partially located outside the contour line of the through hole 32 projected on the first structural member 5, and the contour line of the through hole 32 is located inside the contour line of the clamping space 31 projected in the axial direction of the through hole 32.

[0046] In the embodiment, the first structural member 5 is inserted into the second structural member 3, and the elastic deformation part 2 is simultaneously driven to enter the through hole 32. Since the outer diameter of the elastic deformation part 2 is larger than the size of the through hole 32, the elastic deformation part 2 is compressed when entering the through hole 32. When the first structural member 5 and the second structural member 3 are completely inserted, the elastic deformation part 2 passes through the through hole 32 and enters the clamping space 31. At this time, the elastic deformation part 2 is no longer extruded by the through hole 32, and thus restores the initial deformation. The elastic deformation part 2 after the deformation is clamped in the clamping space 31, and finally the first structural member 5 is locked in the second structural member 3, thereby realizing reliable and stable connection between the first structural member 5 and the second structural member 3, and effectively reducing the probability of loosening or falling off of the first structural member 5 and the second structural member 3 due to various external reasons.

[0047] In an embodiment of the utility model, referring to Figure 1 As shown in the drawings, the elastic deformation part 2 is formed with a stop part 211 at least partially at one end away from the second structural member 3. When the elastic deformation part 2 passes through the through hole 32 and enters the clamping space 31, the elastic deformation part 2 restores the deformation, and the stop part 211 abuts against the side wall of the clamping space 31 (for example, Figure 6 As shown in the drawings), thereby realizing clamping of the elastic deformation part 2 in the clamping space 31 by cooperation of the side wall of the clamping space 31 and the stop part 211, preventing the elastic deformation part 2 from exiting from the clamping space 31, and finally realizing the locking effect between the first structural member 5 and the second structural member 3.

[0048] In an embodiment of the utility model, referring to the accompanying Figure 1 , Figure 2 , Figure 3 As shown in the drawings, the elastic deformation part 2 has a first end 21 close to the first structural member 5 and a second end 22 away from the first structural member 5. The anti-loosening connection structure further comprises a connecting rod 4 arranged between the first structural member 5 and the first end 21. One end of the connecting rod 4 is connected with the first structural member 5, and the other end is connected with the first end 21, that is, the elastic deformation part 2 is fixedly connected with the first structural member 5 through the connecting rod 4.

[0049] In the embodiment, in the length direction of the connecting rod 4, the contour line of the first end 21 projected on the first structural member 5 is at least partially located outside the contour line of the connecting rod 4 projected on the first structural member 5, so that the first end 21 at least partially forms a stop portion 211; that is, the circumferential dimension of the connecting rod 4 is smaller than the circumferential dimension of the first end 21, so that after the elastic deformation portion 2 completely passes through the through hole 32, the connection between the first end 21 and the connecting rod 4 forms a stepped structure (that is, the stop portion 211 in the embodiment), so that the stop portion 211 can abut against the side wall of the clamping space 31, for realizing clamping of the elastic deformation portion 2 in the clamping space 31.

[0050] In the embodiment, as shown in Figure 1 , Figure 2 , Figure 3 In the embodiment, in the length direction of the connecting rod 4, the contour line of the first end 21 projected on the first structural member 5 is at least partially located outside the contour line of the connecting rod 4 projected on the first structural member 5, so that the first end 21 at least partially forms a stop portion 211; that is, the circumferential dimension of the connecting rod 4 is smaller than the circumferential dimension of the first end 21, so that after the elastic deformation portion 2 completely passes through the through hole 32, the connection between the first end 21 and the connecting rod 4 forms a stepped structure (that is, the stop portion 211 in the embodiment), so that the stop portion 211 can abut against the side wall of the clamping space 31, for realizing clamping of the elastic deformation portion 2 in the clamping space 31.

[0051] In the embodiment, in order to make the elastic deformation portion 2 more easily enter the through hole 32, in the length direction of the connecting rod 4, the contour line of the second end 22 projected on the first structural member 5 is located inside the contour line of the through hole 32 projected on the first structural member 5, that is, the circumferential dimension of the elastic deformation portion 2 at the end towards the second structural member 3 is smaller than the dimension of the through hole 32; thus, when the user moves the first structural member 5 towards the second structural member 3 and inserts the first structural member 5 into the second structural member 3, when the elastic deformation portion 2 moves towards the through hole 32 along with the first structural member 5, because the circumferential dimension of the second end 22 is smaller than the dimension of the through hole 32, when the second end 22 moves to a position close to the through hole 32, the second end 22 can directly enter the through hole 32 without being extruded, and under the guidance of the tapered surface extending from the second end 22 to the first end 21, the elastic deformation portion 2 more easily enters the through hole 32 and passes through the through hole 32, which helps to reduce the operation difficulty of the user.

[0052] In the embodiment, as shown in the accompanying Figure 6As shown, the connecting rod 4 in this application can be a rigid structural component or a structural component with certain elastic deformation characteristics (such as a plastic component or a silicone component). When the connecting rod 4 is a rigid structural component, since it cannot undergo compressive deformation, it is necessary to ensure that the outline of the connecting rod 4 projected onto the first structural component 5 does not protrude beyond the outline of the perforation 32 projected onto the first structural component 5. That is, the circumferential dimension of the connecting rod 4 must be less than or equal to the size of the perforation 32, so that the end of the connecting rod 4 near the elastic deformation part 2 can at least partially enter into the perforation 32 (e.g., Figure 6 As shown, the connecting rod 4 is used to snap the elastic deformation part 2 into the snap-fit ​​space 31. Preferably, in this embodiment, the circumferential dimension of the connecting rod 4 can be set to be consistent with the dimension of the through hole 32, so that when the connecting rod 4 enters the through hole 32, there is no gap between the periphery of the connecting rod 4 and the inner wall of the through hole 32. Thus, through the cooperation of the connecting rod 4 and the through hole 32, the relative sway between the first structural member 5 and the second structural member 3 can be limited, ensuring the connection stability between the first structural member 5 and the second structural member 3.

[0053] In this embodiment, when the connecting rod 4 is a structural component with certain elastic deformation characteristics, since it can generate a certain deformation, the circumferential dimension of the connecting rod 4 can be slightly larger than the through hole 32. As a result, when the elastic deformation part 2 is engaged in the engagement space 31, the part of the connecting rod 4 in the through hole 32 is compressed to a certain extent due to the pressure from the wall of the through hole 32, which can further improve the locking effect between the first structural component 5 and the second structural component 3.

[0054] However, it should be noted that the circumferential dimension of the connecting rod 4 should not exceed the circumferential dimension of the first end 21, so that a step is formed between the first end 21 and the connecting rod 4, that is, at least part of the first end 21 forms a stop 211, which is used to match the elastic deformation part 2 with the side wall of the snap-fit ​​space 31, and snap the elastic deformation part 2 into the snap-fit ​​space 31.

[0055] In one embodiment of this utility model, see appendix. Figure 1 , Figure 3 As shown, the elastic deformation portion 2 has a notch 23, and both ends of the notch 23 penetrate the circumferential sidewall of the elastic deformation portion 2; in the length direction of the elastic deformation portion 2, the notch 23 penetrates the second end 22, and the notch 23 extends from the second end 22 to the first end 21; in the length direction of the elastic deformation portion 2, the notch 23 penetrates at least part of the elastic deformation portion 2.

[0056] The gap 23 is arranged in the embodiment, so that the elastic deformation part 2 is more easily to pass through the through hole 32, because when the elastic deformation part 2 is extruded by the wall of the through hole 32 during the process of passing through the through hole 32, the body of the elastic deformation part 2 can be deformed towards the gap 23 (the arrangement of the gap 23 provides a space allowance for the extrusion deformation of the elastic deformation part 2), so that the elastic deformation part 2 can more easily pass through the through hole 32, and the force applied by the user to drive the elastic deformation part 2 to pass through the through hole 32 is reduced.

[0057] In the embodiment, the gap 23 can only pass through part of the elastic deformation part 2 or can pass through the whole elastic deformation part 2 in the length direction of the elastic deformation part 2. When the gap 23 completely passes through the elastic deformation part 2, a larger space allowance can be provided for the deformation of the body of the elastic deformation part 2 (that is, the body of the elastic deformation part 2 can be deformed towards the gap 23 when being extruded by the wall of the through hole 32, and the compression amount generated by the body of the elastic deformation part 2 can be appropriately reduced), so that the user can pass the elastic deformation part 2 through the through hole 32 with a smaller force. When the gap 23 only passes through part of the elastic deformation part 2, the space allowance provided for the deformation of the body of the elastic deformation part 2 is relatively small, so that the user may need to apply a larger force to make the elastic deformation part 2 pass through the through hole 32 (because there is not enough space, the compression amount generated by the body of the elastic deformation part 2 is relatively large, so that the friction between the body of the elastic deformation part 2 and the wall of the through hole 32 is relatively large).

[0058] In an embodiment of the utility model, referring to the drawings Figure 6 , Figure 8 As shown in the drawings, the second structural part 3 has a mounting cavity, the through hole 32 is communicated with the mounting cavity and the outside, and the mounting cavity forms the above-mentioned clamping space 31. When the elastic deformation part 2 passes through the through hole 32 and enters the mounting cavity, the stop portion 211 at the first end 21 abuts against the side wall of the mounting cavity, so that the elastic deformation part 2 is clamped in the mounting cavity.

[0059] In an embodiment of the utility model, referring to the drawings Figure 1 ,

[0062] The first half shell 11 has a first accommodating groove 111 on the side facing the second half shell 12, and the second half shell 12 has a second accommodating groove 121 on the side facing the first half shell 11; along the length direction of the connecting rod 4, the first accommodating groove 111 penetrates the first half shell 11, and the second accommodating groove 121 penetrates the second half shell 12; the first half shell 11 and the second half shell 12 are connected together, so that the first accommodating groove 111 and the second accommodating groove 121 are communicated and form an accommodating cavity 13, and the first structure 5 is sleeved in the accommodating cavity 13, that is, the first structure 5 passes through the accommodating cavity 13, and the two ends of the first structure 5 along the length direction thereof are located outside the accommodating cavity 13.

[0064] As shown in Figure 1 , Figure 2 , Figure 3 , when the connecting piece 1 and the first structure 5 are detachably connected, first, the connecting wire 52 is placed in the second accommodating groove 121 provided on the second half shell 12, then the first half shell 11 is covered on the second half shell 12, and the first half shell 11 and the second half shell 12 are fixedly connected by the clamping structure or the fasteners; when arranged, the circumferential dimension of the accommodating cavity 13 composed of the first accommodating groove 111 and the second accommodating groove 121 should be consistent with the outer diameter dimension of the connecting wire 52, so that when the connecting wire 52 passes through the accommodating cavity 13, the connecting piece 1 can be clamped on the first structure 5.

[0065] Or also can be inserted into the plug terminal 51 in the accommodation cavity 13, at this time need to adjust the size of the first accommodation groove 111 and the second accommodation groove 121 respectively, so that the accommodation cavity 13 can accommodate the plug terminal 51, and the first half shell 11, the second half shell 12 can be clamped on the plug terminal 51.

[0066] In the embodiment, the connecting rod 4 can be connected to the first half shell 11 side towards the second structure 3, or the connecting rod 4 is connected to the second half shell 12 side towards the second structure 3, or the first half shell 11, the second half shell 12 side towards the second structure 3 are connected with the connecting rod 4.

[0067] In the embodiment, the number of connecting rods 4 can be set to multiple, such as two, two connecting rods 4 are distributed on both sides of the first structure 5 (the number of elastic deformation parts 2, the number of through holes 32 are matched); Or three, four, etc.; As preferred, in the embodiment, under the premise of being able to realize reliable locking of the first structure 5 and the second structure 3, the manufacturing cost of the anti-loose structure is reduced as much as possible, and the connecting rod 4 is selected to be provided with two in the application; As shown in Figure 1 、 Figure 3 Two connecting rods 4 are located on both sides of the first structure 5, and the through holes 32 are provided at the corresponding positions of the second structure 3; when the first structure 5 is inserted into the second structure 3, the elastic deformation parts 2 corresponding to the two connecting rods 4 respectively pass through the corresponding through holes 32 and are clamped in the clamping space 31, thereby realizing reliable locking between the first structure 5 and the second structure 3, and ensuring that the first structure 5 and the second structure 3 will not be easily loosened due to various external reasons.
