The nut is sleeved on one end of the bolt passing through the two workpieces, and then the nut is rotated to squeeze the two workpieces so that the two workpieces are fixed to each other.

[0004] However, when the objects are subjected to external force and vibrate, the bolts and nuts will become loose, thereby affecting the fixation between the two objects. Utility Model Content

[0005] The main purpose of the utility model is to provide a convenient latch, aiming to solve the problem that screws are easily loosened.

[0006] To achieve the above-mentioned purpose, the present invention provides a convenient latch, which comprises:

[0007] A latch, a fixing block is provided on the periphery of the latch, and an elastic member is provided at the latching end;

[0008] The latch base is provided with a first groove corresponding to the latch for insertion of the latch, and a clamping groove is provided on the peripheral wall of the first groove, and the fixing block can be inserted into the clamping groove and move therein;

[0009] The latch inserted into the first groove is rotated to engage with the elastic member so that the fixing block is engaged with the engaging groove.

[0010] In some embodiments, the engaging groove includes an insertion section, a rotation section, and a fixed section that are sequentially connected, and the fixed block is fixed to the fixed end by sequentially passing through the insertion section and the rotation section;

[0011] The insertion section is opened in the height direction of the circumference of the first groove, and one end of the insertion section extends to the notch of the first groove;

[0012] The rotating section is provided in a horizontal direction around the first groove, and one end of the rotating section is connected to the other end of the inserting section;

[0013] The fixed section is arranged at the other end of the rotating section and close to the first groove notch.

[0014] In some embodiments, there are multiple clamping slots and fixing blocks, and each clamping slot corresponds to each fixing block one by one.

[0015] In some embodiments, the engaging grooves are evenly arranged around the circumference of the first groove;

[0016] The fixing blocks are evenly arranged on the outer periphery of the latch.

[0017] In some embodiments, the latch is provided with a mounting groove for accommodating the elastic member, and the mounting groove is provided at the center of one end of the latch facing the latch base.

[0031] The utility model proposes a convenient latch 1, referring to Figures 1 to 5 The convenient card bolt 1 includes:

[0032] To achieve the above objectives, the present invention provides a convenient latch 1, which includes:

[0033] The latch 1 has a fixing block 11 on its periphery and an elastic member 12 on its clamping end.

[0034] The latch base 2 is provided with a first groove 21 corresponding to the latch 1 for insertion of the latch 1. The peripheral wall of the first groove 21 is provided with a clamping groove 211. The fixing block 11 can be inserted into the clamping groove 211 and move therein.

[0035] The latch 1 inserted into the first groove 21 is rotated to engage with the elastic member 12 so that the fixing block 11 is engaged with the engaging groove 211 .

[0036] In this embodiment, the surface of the latch 1 provided with the latching end is inserted into the first groove 21 defined in the latch base 2 , wherein the fixing block 11 is inserted into the latching groove 211 .

[0037] The fixing of the clamp 1 and the clamp base 2 is divided into three steps:

[0038] First, align the fixing block 11 on the latch 1 with the engaging groove 211 on the latch base 2. At this time, the elastic member 12 also corresponds to the first groove 21. Then press the latch 1 so that the fixing block 11 on the latch 1 is inserted into the bottom of the engaging groove 211.

[0039] Second, rotate the latch 1 so that the fixing block 11 moves to the bottom of the engaging slot 211 and to the end away from the socket.

[0040] 3. Release the latch 1. At this time, since the elastic member 12 is in a compressed state, when there is no external force pressing the latch 1, the elastic member 12 will lift the latch 1 and the latch base 2, so that the fixing block 11 is fixed to the other end of the latching groove 211 away from the socket.

[0041] Reference Figures 1 to 5 In some embodiments, the engaging groove 211 includes an inserting section 2111, a rotating section 2112, and a fixing section 2113 that are sequentially connected, and the fixing block 11 is fixed to the fixing end through the inserting section 2111 and the rotating section 2112 in sequence;

[0042] The insertion section 2111 is provided in the height direction of the circumference of the first groove 21, and one end of the insertion section 2111 extends to the notch of the first groove 21;

[0043] The rotating section 2112 is provided in a horizontal direction around the first groove 21, and one end thereof is connected to the other end of the inserting section 2111;

[0044] The fixed section 2113 is located at the other end of the rotating section 2112 and close to the notch of the first groove 21 .

[0045] In this embodiment, the opening of the first groove 21 of the insertion section 2111 is the insertion section 2111. When the insertion section 2111 of the bolt 1 is inserted into the first groove 21, the fixing block 11 is inserted into the insertion section 2111 at the first groove 21. When the fixing block 11 abuts the bottom of the insertion section 2111, the bolt 1 is rotated, and the fixing block 11 moves from the insertion section 2111 into one end of the rotating section 2112. As the bolt 1 continues to rotate, the fixing block 11 reaches the other end of the rotating section 2112. At this point, no force is applied to the bolt 1, and the elastic member 12 pushes the bolt 1 in the opposite direction, causing the fixing block 11 to enter the fixing section 2113. Because the fixing section 2113 is compatible with the fixing block 11, the fixing block 11 is engaged in the fixing section 2113. Since the elastic member 12 continuously presses the bolt 1, the fixing member is continuously engaged in the fixing section 2113 due to the force of the elastic member 12. In this way, the bolt 1 is fixed to the base of the bolt 1.

[0046] In another embodiment, the rotating section 2112 is tilted, creating a slope between the rotating section 2112 and the fixed section 2113. In certain applications, a foreign object may contact the latch 1, forcing it to move toward its base. The elastic member 12 is compressed, and vibrations may cause the fixed block 11 to disengage from the fixed section 2113, thereby causing the latch 1 to disengage from its base. The tilted rotating section 2112 forms a slope with the fixed section 2113. In this situation, the fixed section 2113 is less likely to penetrate the rotating section 2112, thereby strengthening the latch 1 and its base.

[0047] Reference Figures 1 to 5 In some embodiments, there are multiple snap-in slots 211 and multiple fixing blocks 11 , and each snap-in slot 211 corresponds to each fixing block 11 one by one.

[0048] In this embodiment, there are multiple engaging grooves 211 and fixing blocks 11, and each engaging groove 211 corresponds to the fixing block 11 one by one. When the bolt 1 needs to be engaged in the base of the bolt 1, it is only necessary to insert the bolt 1 into the first groove 21. At this time, the fixing block 11 may abut against the peripheral side of the opening of the first groove 21, thereby preventing the bolt 1 from being inserted into the engaging groove 211. At this time, it is only necessary to grab the bolt 1 to align the fixing block 11 with the engaging groove 211.

[0049] Reference Figures 1 to 5 In some embodiments, the engaging grooves 211 are evenly arranged around the first groove 21;

[0050] The fixing blocks 11 are evenly arranged on the outer periphery of the latch 1 .

[0051] In this embodiment, in order to ensure that the connection between the clamping bolt 1 and the base of the clamping bolt 1 is evenly stressed, the fit between the clamping bolt 1 and the base of the clamping bolt 1 is made more stable.

[0052] Specifically, there are four fixing blocks 11 evenly arranged on the periphery of the bolt 1. Similarly, there are four engaging grooves 211 evenly arranged on the periphery of the first groove 21. Each fixing block 11 corresponds to a engaging groove 211.

[0053] Reference Figures 1 to 5 In some embodiments, the latch 1 is provided with a mounting groove 13 for accommodating the elastic member 12 , and the mounting groove 13 is provided at the center of one end of the latch 1 facing the latch base 2 .

[0054] In this embodiment, the mounting groove 13 mainly functions to fix the elastic member 12. The mounting groove 13 is opened at the center of the bolt 1 toward the bolt base 2, which can better concentrate the reaction force of the elastic member 12 on the bolt 1 and the fixing block 11. When the mounting groove 13 is biased toward one end, the fixing block 11 will tilt, resulting in an unstable connection between the bolt 1 and the bolt base 2.

[0055] The elastic member 12 can be a spring or an elastic sheet, and its main function is to press the fixing block 11 against the engaging groove 211 .

[0056] Reference Figures 1 to 5 In some embodiments, the fixing block 11 is arranged on the peripheral side of the latch 1 close to the latch base 2 .

[0057] In this embodiment, the fixing block 11 is disposed on the peripheral side of the latch 1 near the latch base 2, which allows the latch 1 to be inserted deeper into the first groove 21 of the latch base. Similarly, the fixing block 11 can also be inserted deeper into the engaging groove 211, thereby making the connection between the latch 1 and the latch base more secure.

[0058] Reference Figures 1 to 5 In some embodiments, the nut is provided with textures around its periphery to increase the friction area.

[0059] In this embodiment, the texture on the circumference of the nut can provide greater friction when the latch 1 is inserted into the first groove 21 and rotated, thereby making it easier to rotate the fixing block 11 into the rear end of the engaging groove 211 .

[0060] The above description is only part or preferred embodiments of the present invention. Neither the text nor the drawings can limit the scope of protection of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the overall concept of the present invention, or direct / indirect application in other related technical fields are included in the scope of protection of the present invention.
