DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0025] See also Figure 1-8 The utility model provides the following technical solutions: a round cake-shaped lock, including a round cake connecting seat 1, a first joint 2 and a second joint 3 are respectively arranged at both ends of the round cake connecting seat 1, and also includes a limit pin 4 and an elastic rubber ring 5, the second joint 3 and the round cake connecting seat 1 are assembled by snap-fitting, the limit pin 4 and the elastic rubber ring 5 are assembled in the round cake connecting seat 1 by snap-fitting the second joint 3 and the round cake connecting seat 1, and a snap-fitting part matched by the elastic rubber ring 5 is also provided between the limit pin 4 and the first joint 2.

[0026] Specifically, the circular connecting seat 1 includes a vertically opened movable hole 11 and a rubber ring groove 12 connected to the bottom of the movable hole 11, the limit pin 4 is installed in the movable hole 11, the elastic rubber ring 5 is installed in the rubber ring groove 12, and the upper end of the limit pin 4 protrudes from the top of the circular connecting seat 1.

[0027] Specifically, a first connection hole 13 is opened on one side of the circular connecting seat 1, and a second connection hole 14 is opened on the other side. The first connection hole 13 and the second connection hole 14 are both interconnected with the movable hole 11, and the first connection hole 13 and the first joint 2 are mutually inserted.

[0028] Specifically, a clamping sleeve 31 is provided at the front end of the second connector 3, and a clamping ring 32 is provided on the outside of the clamping sleeve 31 to engage with the inner side of the second connecting hole 14. An elastic groove 33 is also provided on the clamping sleeve 31. In this embodiment, the hollowness inside the clamping sleeve 31 and the setting of the elastic groove 33 both provide elastic force for the clamping ring 32 to engage. At the same time, the hollowness inside the clamping sleeve 31 also forms an avoidance space for the insertion of the front end of the plug 21, which can control the volume of the entire lock while achieving stable and convenient connection, making the lock more flexible and compact.

[0029] Specifically, a socket 41 is provided on one side of the limit pin 4, and a slot 42 is provided on the other side. The front end of the sleeve 31 is also located in the slot 42. In this embodiment, by matching the front end of the sleeve 31 with the slot 42, the slot 42 can slide outside the sleeve 31, which can be used for limiting the position of the limit pin 4 and the elastic rubber ring 5 after they are installed, and at the same time does not affect the snap-fit ​​between the limit pin 4 and the first joint 2.

[0030] Specifically, a plug 21 is provided at the front end of the first connector 2, and an annular groove 22 which is engaged with the card slot 42 is provided between the first connector 2 and the plug 21. In this embodiment, both the plug 21 and the annular groove 22 can be inserted into the socket 41, and the front end of the plug 21 is also located on the inner side of the card sleeve 31, and the annular groove 22 and the card slot 42 are engaged by an elastic rubber ring 5.

[0031] Specifically, buffer countersunk holes 51 are provided at the upper and lower ends of the inner side of the elastic rubber ring 5, and an annular buffer rib 52 is also provided at the middle part of the outer side of the elastic rubber ring 5. The buffer countersunk holes 51 and the buffer rib 52 in this embodiment both have an energy-absorbing effect, providing deformation space for the elastic rubber ring 5 after pressing, ensuring the elastic effect, and further ensuring the locking effect between the limit pin 4 and the first joint 2.

[0032] The working principle and use process of the utility model are as follows: during the assembly process, the elastic rubber ring 5 is first installed into the rubber ring groove 12, and then the limit pin 4 is inserted into the movable hole 11 and contacts the elastic rubber ring 5, the limit pin 4 is rotated to make the clamping groove 42 part correspond to the second connecting hole 14, and the clamping sleeve 31 at the front end of the second joint 3 is inserted into the second connecting hole 14, and the clamping ring 32 is clamped on the inner side of the second connecting hole 14 under the action of the elastic groove 33, at this time, the front end of the clamping sleeve 31 is inserted into the clamping groove 42, and the limit pin 4 and the elastic rubber ring 5 are also assembled with the round cake connecting seat 1;

[0033] When wearing: pinch the round connection base 1 and the first connector 2, insert the plug 21 and the ring groove 22 at the front end of the first connector 2 into the first connection hole 13, the plug 21 passes through the insertion hole 41 and is located inside the clamping sleeve 31, at this time, the ring groove 22 part and the clamping groove 42 are engaged with each other under the action of the elastic rubber ring 5, and the locking is completed;

[0034] When removing: after pressing the limit pin 4 inwardly, the elastic rubber ring 5 is compressed, and after the limit pin 4 moves downward, the annular groove 22 is disengaged from the engagement with the clamping groove 42, and the first joint 2 can be taken out from the round cake connecting seat 1. During the process of pressing the limit pin 4 inwardly, the clamping groove 42 will also slide downward along the outside of the clamping sleeve 31, which ensures the connection effect of the second joint 3 and the limit pin 4 while playing a avoidance effect, thereby facilitating the rapid separation of the first joint 2.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
