DETAILED DESCRIPTION

[0028] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0029] Example 1

[0030] like Figures 1-5 As shown, a foldable connecting joint is used to be installed between two adjacent rods 12 of police equipment. When the police equipment needs to be folded, it is only necessary to fold the foldable connecting joint 11.

[0031] The foldable connecting joint 11 includes a first connecting member 2 and a second connecting member 3 rotatably connected by a rotating shaft 1, the first connecting member 2 includes a self-locking female head 4 and a first mounting seat 5 fixedly connected, the second connecting member 3 includes a self-locking male head 6 and a second mounting seat 7 fixedly connected, the first mounting seat 5 and the second mounting seat 7 are respectively inserted into two adjacent rod bodies 12 and fixed thereto; the self-locking female head 4 and the self-locking male head 6 can be engaged and locked or separated and unlocked; the rotating shaft 1 is offset from the first connecting member 2 and the second connecting member 3 along the length direction perpendicular to the rod body 12.

[0032] When the self-locking female head 4 and the self-locking male head 6 are in a locked state, the first connecting member 2 and the second connecting member 3 are unfolded in a straight line, and the rotating shaft 1 is located on the same side of the first connecting member 2 and the second connecting member 3 (such as Figure 1 As shown), when the self-locking female head 4 and the self-locking male head 6 are in the unlocked state, the first connecting member 2 and the second connecting member 3 can be flipped 180 degrees relative to each other. At this time, the rotating shaft 1 is located between the two opposite sides of the first connecting member 2 and the second connecting member 3 (as shown in FIG. Figure 2 shown).

[0033] In the traditional connecting joint, the rotating shaft 1 is located in the middle of the two connecting parts, so the turning angle of the connecting parts will be limited. In the present invention, the rotating shaft 1 is set away from the two connecting parts, such as Figure 7In the shown unfolded state, the rotation shaft 1 is located below the first connecting piece 2 and the second connecting piece 3, assuming that the first connecting piece 2 is fixed, when rotating the second connecting piece 3, due to the self structure of the first connecting piece 2 and the second connecting piece 3 will not interfere, so the second connecting piece 3 can rotate 180 degrees around the rotation shaft 1, so that the two rod bodies 12 are folded in parallel. The self-locking male head 6 and the self-locking female head 4 in the utility model are used to realize the locking of the unfolded state of the police equipment, so that the two rod bodies 12 form a stable straight rod. Secondly, the first mounting seat 5 and the second mounting seat 7 in the utility model can be inserted into the rod body 12. Compared with the traditional structure in which hinges are only installed on the outside of the rod body 12, since the first mounting seat 5 and the second mounting seat 7 are separate fixed components, and the rotating part is arranged at the rotation shaft 1 outside the rod body 12, the first mounting seat 5 and the second mounting seat 7 can be provided with multiple fixing surfaces for improving the connection strength.

[0034] From the operation mode, the utility model is composed of two relative motion components, after the foldable connecting joint 11 is installed on the police equipment, when folding is needed, one of the connecting pieces can be fixed, and only the rod body 12 connected with the other connecting piece needs to be rotated. Compared with the structure in which two folding pieces need to be rotated in the patent No. CN202323422108.3, the utility model is more convenient to operate, the connection structure is simplified, and the risk of pinching hands will not occur.

[0035] The self-locking female head 4 and the self-locking male head 6 are matched parts that can be automatically locked without external force, for example, mutually matched hooks, bolts and the like, and can also be directly purchased in the market. The structure of the self-locking female head 4 and the self-locking male head 6 shown in the drawing of the utility model is as follows:

[0036] The self-locking female head 4 comprises a base 401, a limiting column 402, a limiting head 403 and a reset spring 404. The base 401 is fixed with the first connecting piece 2. The limiting head 403 is fixed at one end of the limiting column 402. The reset spring 404 is sleeved outside the limiting column 402. The limiting head 403 and the reset spring 404 are respectively abutted on both sides of the base 401. The limiting column 402 passes through the base 401, and the reset spring 404 is compressed between the base 401 and the limiting column 402. The self-locking male head 6 has a limiting hole 601 for inserting the end of the limiting column 402, so that the self-locking female head 4 and the self-locking male head 6 are buckled and locked. The base 401 is a fixed component, which serves as the installation basis of other movable components. Meanwhile, the base 401 is also used for limiting the limiting head 403 and the reset spring 404. In the free state, the reset spring 404 extrudes the limiting column 402, so that the limiting column 402 is inserted into the limiting hole 601. When the limiting head 403 is pulled, the limiting column 402 is also lifted and separated from the limiting hole 601. Meanwhile, the reset spring 404 is further compressed under the limitation of the base 401, and stores energy for resetting the limiting column 402.

[0037] AsFigure 3 and Figure 5 As shown in the figure, the limiting head 403 and the reset spring 404 are located on the upper and lower sides of the base 401, the limiting head 403 is exposed outside, which is convenient for the user to pull the limiting head 403, the limiting column 402 penetrates through the base 401, and the reset spring 404 and the limiting column 402 are hidden downward in the interior of the first connecting piece 2, the lower end of the limiting column 402 has a protrusion 4021 (as shown in the figure), and the upper end of the reset spring 404 abuts against the lower surface of the base 401 and the lower end abuts against the upper surface of the protrusion 4021. Figure 4 and Figure 6 When the limiting head 403 is pulled upward, the protrusion 4021 of the limiting column 402 drives the reset spring 404 to move upward, and when the limiting head 403 is released, the reset spring 404 drives the limiting column 402 to reset downward until the limiting head 403 abuts against the upper surface of the base 401.

[0038] The limiting column 402 is arranged vertically to the length direction of the rod body 12, the limiting column 402 penetrates through the base 401, so that the base 401 is parallel to the length direction of the rod body 12, the base 401 can fill the space between adjacent rod bodies 12, the second connecting piece 3 is fixed with a limiting plate 602, the limiting plate 602 and the base 401 are arranged in parallel, and a limiting hole 601 is located on the limiting plate 602, as shown in the figure, the limiting column 402 is vertically inserted into the limiting hole 601 downward. Figure 3

[0039] The base 401 can be a single panel, in the specific embodiment described in the utility model, the base 401 is a C-shaped structure, the C-shaped opening of the base 401 faces the direction of the second connecting piece 3, and the reset spring 404 is located in the interior of the base 401; the limiting column 402 penetrates through the two end side plates of the base 401, the C-shaped structure of the base 401 can surround the reset spring 404, while ensuring the linear motion of the limiting column 402. The limiting plate 602 is connected with a baffle 603 at one end facing the second mounting seat 7, when the self-locking female head 4 and the self-locking male head 6 are buckled and locked, the baffle 603 abuts against the side plate end surface of the base 401. As shown in the figure, the two side plates of the base 401 are located on the upper and lower sides respectively, the side plate at the upper end acts as an outer connecting plate and is connected with the end portions of adjacent two rod bodies 12, and the side plate at the lower end is used for abutting against the baffle 603, thereby playing a role of limiting the extreme position of expansion. Figure 3 Figure 7 As shown in the figure, when the self-locking female head 4 and the self-locking male head 6 are buckled and locked, the side plates at both ends of the base 401 abutting against the limiting head 403 are respectively connected with the end surfaces of the two rod bodies 12.

[0040] The first mounting seat 5 and the second mounting seat 7 are similar in structure:

[0041] ​​The first mounting seat 5 and the second mounting seat 7 each comprise one or more mounting plates 8 arranged in abutment with the inner surface of the rod body 12 and fixed with the rod body 12 and a connecting plate 9 connected between the mounting plates 8. The mounting plates 8 are in abutment with the inner surface of the rod body 12, which has the functions of positioning, increasing the contact area and improving the connection strength, and the connecting plate 9 is used to ensure the stability of the first mounting seat 5 and the second mounting seat 7.

[0042] The utility model can be used for the connection of the rod body 12 with a circular, rectangular or other arbitrary shape cross section, as long as the two mounting seats are designed according to the cross section shape of the rod body 12.

[0043] The embodiment takes the rod body 12 with a rectangular cross section as an example to describe the structure of the first connecting piece 2 and the second connecting piece 3. As shown in Figure 1 The outer side side plate of the base 401 in the self-locking female head 4 is perpendicular to the mounting plate 8, and the two mounting plates 8 of the first mounting seat 5 extend outwardly in the direction of the self-locking female head 4, and the outer plate 10 is located outside the rod body 12, and the outer plate 10 is connected with the outer side side plate of the base 401 to form an outer frame, which is used to butt joint with the two rod bodies 12, so that the folding part of the folding rod is more flat.

[0044] Embodiment two

[0045] In the above embodiment, when the limiting column 402 is inserted into the limiting hole 601, the self-locking male head 6 and the self-locking female head 4 are locked, and when it is necessary to unlock or enter the locked state from the unlocked state, the limiting head 403 is pulled outwardly to make the limiting column 402 leave the limiting hole 601, so as to provide space for the rotation of the second connecting piece 3. However, when the foldable connecting joint 11 is unfolded, one hand holds the first connecting piece 2, and the other hand straightens the second connecting piece 3, so that the limiting head 403 cannot be pulled, and therefore it is difficult for one person to operate. Therefore, the embodiment is improved as follows:

[0046] The limiting plate 602 is connected with a guide plate 604 at the end away from the second mounting seat 7, a chamfer 605 is arranged at the connection between the limiting plate 602 and the guide plate 604, and the end of the limiting column 402 matched with the limiting hole 601 has an arc surface 4022 extending to the side surface of the second connecting piece 3. As shown in Figure 3 The second connecting piece 3 is located at the right side of the first connecting piece 2, the arc surface 4022 is located at the right side of the bottom of the limiting column 402, and the chamfer 605 is located at the left end of the limiting plate 602. When the second connecting piece 3 is folded, the self-locking male head 6 is separated from the first connecting piece 2 to the right from the position shown in Figure 3 Figure 5 ​When the second connecting piece 3 is unfolded, the second connecting piece 3 is rotated counterclockwise around the rotating shaft 1, the male head 6 is gradually inserted into the female head 4, and the chamfer 605 first contacts the arc surface 4022; under the arc guiding of the two, the limiting plate 602 can extrude the limiting column 402, the limiting column 402 moves upward until the limiting plate 602 is horizontal, and at this time, the limiting column 402 is inserted into the limiting hole 601.

[0047] Through the improvement of the embodiment, when the foldable connecting joint 11 is unfolded, it is only needed to directly rotate and straighten the rod body 12 connecting two connecting pieces, without further pulling the limiting head 403, and a single person can operate.

[0048] Embodiment three

[0049] On the basis of the embodiment two, in order to strengthen the locking effect when the foldable connecting joint 11 is unfolded, the embodiment is further improved as follows: one end of the limiting column 402 matched with the limiting hole 601 has a limiting plane 4023 arranged opposite to the arc surface 4022, when the female head 4 is buckled and locked with the male head 6, the limiting plane 4023 abuts against the inner surface of the limiting hole 601. Figure 3 As shown, the baffle 603 is used for preventing the second connecting piece 3 from rotating counterclockwise excessively when unfolded, and the cooperation of the limiting plane 4023 and the inner surface of the limiting hole 601 is used for ensuring that the two rod bodies 12 are in a stable and flat state, and avoiding that the second connecting piece 3 is deformed along the clockwise direction to the folded state.

[0050] Embodiment four

[0051] A foldable rod comprises two rod bodies 12 and the foldable connecting joint 11 described above, the foldable connecting joint 11 is used for connecting two adjacent rod bodies 12, as shown in the figure, Figure 7 When the foldable rod is in an unfolded state, the male head 6 of the foldable connecting joint 11 is accommodated in the female head 4 and surrounded by the outer plate 10 of the female head 4, and the overall appearance is still a relatively regular rectangle; when the foldable rod is in a folded state, the foldable connecting joint 11 is still connected to the two rod bodies 12, without the need to disassemble any part, and the rod bodies 12 can be folded to be parallel to each other, improving the space utilization.
