Description

Technical Field

[0001] This invention relates to the technical field of communication device connection components, and more particularly to a quick-connect lock and a structure having the quick-connect lock. Background Technology

[0002] Because the installation of existing equipment or accessories inside the racks uses bolts, the following problems are likely to occur during equipment installation: 1) The installation space for some equipment is too small to tighten the bolts; 2) When bolts and nuts are connected, nuts often fall into the existing equipment and cannot be removed, causing malfunctions or safety risks; 3) Bolt installation is relatively cumbersome, and problems such as construction teams forgetting to install some bolts often occur. Summary of the Invention

[0003] Therefore, there is a need to provide a quick-connect lock and a structure with the quick-connect lock to solve the problems of small installation space inside the rack and difficulty in locking existing connectors.

[0004] To achieve the above objectives, the inventors provide a quick-connect lock, comprising: a first post, a second post, a ring-shaped sliding buckle, a first folding rod, a second folding rod, and an elastic element, wherein one end of the first post is hinged to the hinged end of the second post, and the ring-shaped sliding buckle is sleeved on the second post;

[0005] One end of the first folding rod is hinged to a ring-shaped sliding buckle, the other end of the first folding rod is hinged to one end of the second folding rod, the other end of the second folding rod is hinged to the insertion end of the second column, one end of the elastic element is connected to the insertion end of the second column, and the other end of the elastic element is connected to the ring-shaped sliding buckle.

[0006] When the first column and the second column are in the same direction, the first folding rod and the second folding rod are in the same direction, and the ring-shaped sliding buckle can drive the elastic element to slide from the second column to the first column; when the first column and the second column are in the folded state, the first folding rod and the second folding rod are in the folded state, and the ring-shaped sliding buckle only slides on the second column.

[0007] Furthermore, the simple locking device for connection also includes a post handle, which is connected to the end of the first post away from the second post.

[0008] Furthermore, the ring-shaped sliding buckle includes a limiting part and a buckling part connected together. The cross-sectional area of ​​the buckling part is smaller than the cross-sectional area of ​​the limiting part, and the first folding rod is hinged to the end of the buckling part away from the limiting part.

[0009] Furthermore, the insertion end of the second column is provided with a conical cap, and the hinge point between the second folding rod and the second column is located below the conical cap. The conical cap limits the rotation angle of the second folding rod.

[0010] Furthermore, the elastic element is a spring, and the spring is sleeved on the second column;

[0011] When the hinged connection between the first column and the second column is in the first position, the spring can slide onto the first column along with the ring-shaped sliding buckle.

[0012] Furthermore, multiple sets of the first and second folding rods are provided, and the first and second folding rods are arranged in a circumferential array along the ring-shaped sliding buckle.

[0013] Furthermore, multiple sets of the first and second folding rods are provided, and the first and second folding rods are arranged in a circumferential array along the ring-shaped sliding buckle.

[0014] Furthermore, the first column and the second column are of the same length.

[0015] Furthermore, when the first folding rod and the second folding rod are in the folded state, the first folding rod is in the horizontal state.

[0016] The inventors also provide a structure with a quick-connect lock, including a first frame, a second frame, and a quick-connect lock. The quick-connect lock is the quick-connect lock described in any of the above technical solutions. The first frame and the second frame are provided with mounting holes, and the quick-connect lock passes through the mounting holes of the first frame and the second frame.

[0017] Unlike existing technologies, the above technical solution has the following advantages: When the quick-connect lock is used for mounting holes, with the first and second folding rods in the same direction, the insertion end of the second column can smoothly insert the first and second folding rods into the mounting hole. Then, the first and second folding rods are folded, ensuring a certain distance between the hinge point of the first and second folding rods and the second column, preventing them from detaching from the mounting hole. The innovative use of an integrated quick-connect lock eliminates the need for accessories and installation, allowing for the replacement of bolts for cabinet equipment installation. It is suitable for scenarios where rack columns are connected and locked to equipment or other supporting blind flanges, or for other scenarios where bolt fixing is required for hole connections.

[0047] Please see Figures 1 to 4 This embodiment of a quick-connecting latch 03 includes: a first column 1, a second column 2, a ring-shaped sliding latch 3, a first folding rod 4, a second folding rod 5, and an elastic element 6. One end of the first column 1 is hinged to the hinged end of the second column 2, and the ring-shaped sliding latch 3 is sleeved on the second column 2.

[0048] One end of the first folding rod 4 is hinged to the ring-type sliding buckle 3, the other end of the first folding rod 4 is hinged to one end of the second folding rod 5, the other end of the second folding rod 5 is hinged to the insertion end of the second column 2, one end of the elastic element 6 is connected to the insertion end of the second column 2, and the other end of the elastic element 6 is connected to the ring-type sliding buckle 3.

[0049] When the first column 1 and the second column 2 are in the same direction, the first folding rod 4 and the second folding rod 5 are in the same direction, and the ring-shaped sliding buckle 3 can drive the elastic element 6 to slide from the second column 2 to the first column 1; when the first column 1 and the second column 2 are in a folded state, the first folding rod 4 and the second folding rod 5 are in a folded state, and the ring-shaped sliding buckle 3 only slides on the second column 2.

[0050] The first column 1, the second column 2, the ring-shaped sliding buckle 3, the first folding rod 4, and the second folding rod 5 are made of materials such as steel, iron, or plastic. The first column 1, the second column 2, the first folding rod 4, and the second folding rod 5 are all columnar structures, specifically cylindrical, prismatic, or frustum-shaped. Specifically, the first column 1 and the second column 2 have the same cross-section and length, and the first folding rod 4 and the second folding rod 5 have the same cross-section and length. The ring-shaped sliding buckle 3 is a columnar structure with a through hole in the center. The ring-shaped sliding buckle 3 passes through the through hole in the center onto the first column 1 or the second column 2. The through hole in the ring-shaped sliding buckle 3 and the first column 1 and the second column 2 are in clearance fit, allowing the ring-shaped sliding buckle 3 to move freely on the first column 1 and the second column 2.

[0051] Specifically, the total length of the first folding rod 4, the second folding rod 5, and the ring-shaped sliding buckle 3 is less than the total length of the first column 1 and the second column 2. This has the advantage that when the first column 1 and the second column 2 are in the same direction, the first folding rod 4 and the second folding rod 5 are also in the same direction, and the ring-shaped sliding buckle 3 connected to the first folding rod 4 remains fitted onto the first column 1, preventing it from detaching. In some preferred embodiments, the simple locking mechanism also includes a column handle 11, which is connected to the end of the first column 1 furthest from the second column 2. That is, when the first column 1 and the second column 2 are in the same direction, the first folding rod 4 and the second folding rod 5 are also in the same direction, and the column handle 11 effectively prevents the ring-shaped sliding buckle 3 from detaching from the first column 1.

[0052] When the first folding rod 4 and the second folding rod 5 are in the folded state, the first folding rod 4, the second folding rod 5, and the ring-shaped sliding buckle 3 are all located on the side of the second column 2. At this time, the hinge structure between the first column 1 and the second column 2 folds the first column 1 and the second column 2 at a certain angle, which can prevent the ring-shaped sliding buckle 3 from slipping off the second column 2 and can always maintain the folded state of the first folding rod 4 and the second folding rod 5. The folding angle of the first column 1 and the second column 2 is preferably 90°. After the first column 1 and the second column 2 are folded at 90°, a limiting effect is generated between the first column 1 and the second column 2. This limiting effect needs to be manually removed in order to make the first column 1 and the second column 2 be in the same direction.

[0053] It is particularly important to mention that the folded state of the first folding rod 4 and the second folding rod 5 means that the hinge of the first folding rod 4 and the second folding rod 5 moves away from the second column 2.

[0054] When the first column 1 and the second column 2 are selected as columnar structures with the same cross-section, and the first column 1 and the second column 2 are in the same direction, the first column 1 and the second column 2 are on the same straight line. The cross-section of the hinge of the first column 1 and the second column 2 is the same size as the cross-section of the first column 1 and the cross-section of the second column 2. The ring-type sliding buckle 3 can slide on the first column 1, the second column 2 and the hinge of the two.

[0055] When the ring-type sliding buckle 3 is fitted onto the second column 2, the first folding rod 4 and the second folding rod 5 are in a folded state, meaning they are not in the same direction and form a certain angle. The hinge point of the first folding rod 4 and the second folding rod 5 is a certain distance from the second column 2. When the first folding rod 4 and the second folding rod 5 are folded, the distance between their hinge point and the second column 2 is greater than the distance between their hinge point and the second column 2 when they are in the same direction. When this quick-connect lock 03 is used for the mounting hole, when the first folding rod 4 and the second folding rod 5 are in the same direction, the insertion end of the second column 2 can smoothly insert the first folding rod 4 and the second folding rod 5 into the mounting hole. Then, the first folding rod 4 and the second folding rod 5 are folded so that the hinge point of the first folding rod 4 and the second folding rod 5 is a certain distance from the second column 2, and the first folding rod 4 and the second folding rod 5 cannot be disengaged from the mounting hole after folding.

[0056] When using the quick-connect lock 03, first rotate the first column 1 and the second column 2 until they are in the same direction. The ring-shaped sliding buckle 3 can then slide from the second column 2 to the first column 1. During this process, the elastic element 6 is gradually stretched, and the first folding rod 4 and the second folding rod 5 gradually open from the folded state to be in the same direction. Insert the insertion end of the second column 2 into the mounting hole. The insertion end of the second column 2, along with the first folding rod 4 and the second folding rod 5, is inserted into the mounting hole together. After both the first folding rod 4 and the second folding rod 5 are inserted into the mounting hole, the ring-shaped sliding buckle 3 is then... Pushing from the first column 1 to the second column 2 causes the first folding rod 4 and the second folding rod 5 to fold. During this process, the elastic element 6 gradually shortens and returns to its original length. After folding, the first folding rod 4 and the second folding rod 5 will not detach from the mounting hole. After folding, the ring-shaped sliding buckle 3 is located on the first column 1. Finally, folding the first column 1 and the second column 2 prevents the ring-shaped sliding buckle 3 from slipping off the second column 2, thus keeping the ring-shaped sliding buckle 3 on the second column 2 and keeping the first folding rod 4 and the second folding rod 5 in a folded state.

[0057] In some preferred embodiments, the annular sliding buckle 3 includes a connected limiting part 31 and a buckling part 32. The cross-sectional area of ​​the buckling part 32 is smaller than that of the limiting part 31. The first folding rod 4 is hinged to the end of the buckling part 32 away from the limiting part 31. The buckling part 32 is a cylindrical, frustum-shaped, or prismatic structure with a through hole in the middle. The limiting part 31 is a cylindrical, frustum-shaped, prismatic, or other columnar structure with an irregular outer peripheral surface and a through hole in the middle. Its advantage is that after the quick-connect lock 03 is installed, the buckling part 32 of the annular sliding buckle 3 is inserted into the mounting hole, and the limiting part 31 is restricted outside the mounting hole. The limiting part 31 is used to limit the positional relationship between the annular sliding buckle 3 and the mounting hole. Specifically, the cross-section of the buckling part 32 is smaller than the cross-section of the mounting hole, and the cross-section of the limiting part 31 is larger than the cross-section of the mounting hole. When the quick-connecting latch 03 is installed and used, the first folding rod 4 and the second folding rod 5 are both located inside the mounting hole, the latch part 32 passes through the mounting hole, and the limiting part 31 is located outside the mounting hole.

[0058] In some preferred embodiments, the insertion end of the second column 2 is provided with a conical cap 7, and the hinge point between the second folding rod 5 and the second column 2 is located below the conical cap 7. The conical cap 7 limits the rotation angle of the second folding rod 5. When the second folding rod 5 is in the folded state, its rotation limit contacts the bottom of the conical cap 7. The cross-section of the conical cap 7 is smaller than the cross-section of the mounting hole, allowing the conical cap 7 to be smoothly inserted into the mounting hole. The hinge point between the second folding rod 5 and the second column 2 is located below the conical cap 7, that is, the second folding rod 5 is hinged to the bottom of the conical cap 7.

[0059] In some preferred embodiments, the elastic element 6 is a spring, which is sleeved on the second column 2. When the hinged state of the first column 1 and the second column 2 is in the first position, the spring can slide onto the first column 1 with the ring-type sliding buckle 3. Specifically, the spring is a tension spring. When the first folding rod 4 and the second folding rod 5 are in the folded state, the spring is in its original length or close to its original length. When the first folding rod 4 and the second folding rod 5 are in the same direction, the spring is in a stretched state. The restoring force of the spring helps the first folding rod 4 and the second folding rod 5 to automatically fold after entering the mounting hole and automatically limit and lock in the mounting hole. During the insertion or removal process, external force is required to stretch the spring, change the shape of the first folding rod 4 and the second folding rod 5, and then pull them out.

[0060] In some preferred embodiments, multiple sets of the first folding rod 4 and the second folding rod 5 are provided, and the first folding rod 4 and the second folding rod 5 are arranged in a circumferential array along the annular sliding buckle 3. The advantage is that when the first folding rod 4 and the second folding rod 5 are folded, they form an umbrella-shaped structure, which can prevent the quick-connect lock 03 from dislodging from the mounting hole.

[0061] In some preferred embodiments, when the first folding rod 4 and the second folding rod 5 are in the folded state, the first folding rod 4 is in a horizontal state. The advantage of this is that when the first folding rod 4 and the second folding rod 5 are in the folded state, the contact area between the first folding rod 4 and the mounting hole increases, improving the stability of the quick-connect lock 03 and preventing the quick-connect lock 03 from wobbling within the mounting hole.

[0062] like Figure 5 and Figure 6 As shown, the inventor also provides a structure with a quick-connect latch 03, including a first frame 01, a second frame 02 and a quick-connect latch 03. The quick-connect latch 03 is the quick-connect latch 03 in any of the above technical solutions. The first frame 01 and the second frame 02 are provided with mounting holes, and the quick-connect latch 03 passes through the mounting holes of the first frame 01 and the second frame 02. The first frame 01 can be a communication equipment frame, an air supply equipment frame, or other equipment frame. The second frame 02 can be an embedded device built into the first frame 01. During installation, the quick-connect lock 03 is installed by aligning the mounting holes of the first frame 01 and the second frame 02, inserting the quick-connect lock 03 into the mounting holes of the first frame 01 and the second frame 02, so that the first folding rod 4 and the second folding rod 5 are in a folded state, and then folding the first column 1 and the second column 2, preferably folding the first column 1 downwards, so that the first column 1 forms a latch, ensuring that the latch does not loosen during vibration, pressing, or misoperation, and achieving the effect of firmly locking the item.

[0063] The inventor believes that when locking the equipment or accessories inside the frame with the quick-connect lock 03, simply align the equipment mounting hole with the frame column opening, pull the ring-type sliding buckle 3 towards the first column 1 with one hand until the first folding rod 4 and the second folding rod 5 form a straight line, insert it into the mounting hole and release your hand. After the quick-connect lock 03 springs back, fold the first column 1 downwards by 90 degrees. When removing the equipment, simply reverse the operation. This achieves the purpose of easy and quick installation and removal of equipment, and operation without considering space. It is a fixing method that can replace bolts in some scenarios.

[0064] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
