Description

Technical Field

[0001] The utility model relates to the technical field of batons, in particular to a blade swing locking structure of a mechanical baton. Background Art

[0002] Mechanical batons are generally composed of three sections of hollow tubes. The first section is the striking section, the second section is the middle section, and the third section is the grip section. By using the lock installed at the rear end of the striking section, the slotted inner wall of the front end tube of the middle section, the lock installed at the rear end, and the slotted inner wall of the front end of the grip section, the baton is locked in the unfolded state after being thrown out. When it needs to be retracted, the unlocking button device installed at the end of the grip section is used to unlock and retract the baton. Carry it in the retracted state and use it in the unfolded state. Mechanical batons have the significant advantage of being easy to use and are the first choice for modern single police equipment. However, the locking performance requirements in the unfolded state are high, and the structure is relatively complex. Mechanical failures are prone to occur during use, and the failure and scrapping of batons pose a threat to the personal safety of law enforcement personnel.

[0003] The existing mechanical baton locking structure mainly has the following two methods:

[0004] Two symmetrical semicircular plates and two springs (commonly known as drum-disc locks) are installed at one end of a tube and inserted into another tube with a groove on the inner wall. During relative movement, the radial elastic force of the spring causes the drum disc to be stuck in the groove, forming a lock. The disadvantage of this lock is that when the axial poking force is greater than the spring force of the drum disc, the lock fails (the striking section or the middle section retracts).

[0005] 2. Eight cam pieces are used to surround the inner wall of one end of the tube to form a hole. A movable rod is inserted into the hole and passed through another tube with a groove on the inner wall. When moving relatively, the movable rod is pulled to make the eight cam pieces swing and get stuck in the groove at the same time, forming a lock. The disadvantage of this lock is that when a slight axial impact force is applied, the cam will self-lock and the lock will fail. (Neither the striking section nor the middle section can be retracted). Utility Model Content

[0020] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0021] like Figure 1-5 As shown, a blade swing locking structure of a mechanical baton comprises: a three-section telescopic baton body, which comprises a striking section 1, an intermediate section 2 and a grip section 3 which are connected in sequence, wherein the striking section 1, the intermediate section 2 and the grip section 3 are all hollow cylinders, the striking section 1 is inserted into the intermediate section 2 to freely extend and retract, and the intermediate section 2 is inserted into the grip section 3 to freely extend and retract; a tail cover 4 is fixed at the bottom end of the grip section 3, an unlocking button 5 is fixed in the tail cover 4, and the unlocking button 5 is connected to an unlocking rod 6; the striking section 1 and the intermediate section 2 are connected to the grip section 3, and the unlocking button 5 is connected to the unlocking rod 6; the striking section 1 and the intermediate section 2 are connected to the grip section 3, and the grip section 3 is connected to the grip section 3 ... The bottom end of each intermediate section 2 is fixed with a blade swing lock assembly 7, which includes a guide bowl 71, which is connected to a pressure plate 72, on which a threaded mandrel 73 is fixed, which is connected to a threaded seat 74, and between the pressure plate 72 and the threaded mandrel 73 are arranged a first blade lock core 76, a second blade lock core 77 and a third blade lock core 78 which are connected in sequence by a tension spring 75, and the threaded mandrel 73 and the threaded seat 74 are fixed by a nut 79. The intermediate section 2 and the handle section 3 are both provided with a pipe groove 10 which matches the locking portion 763.

[0022] It should be noted that the threaded seat 74 is fixed to the rear ends of the striking section 1 and the intermediate section 2, and is detachably connected. Furthermore, threads are provided on the threaded seat 74, and it is detachably connected to the striking section 1 and the intermediate section 2 via threads.

[0023] The guide bowl 71 is a bowl-shaped structure concave inwards and is provided with a through hole 8 for inserting the unlocking rod 6. The first blade lock core 76, the second blade lock core 77 and the third blade lock core 78 each include a blade body 761, an unlocking hole 766, a tension spring hole 762, a locking portion 763, a tension spring hook 764 and a spindle hole 765 provided on the blade body 761; the threaded spindle 73 passes through the spindle hole 765 and is connected to the threaded seat 74.

[0024] It should be noted that the first blade lock core 76, the second blade lock core 77 and the third blade lock core 78 are connected by a tension spring 75, and the tension spring 75 is fixed in the tension spring hook 764 and the tension spring hole 762 of two adjacent blade lock cores, and is used to connect two adjacent blade lock cores. For example, the tension spring hole 762 of the first blade lock core 76 fixes one end of the tension spring 75, and the other end of the tension spring 75 is connected to the tension spring hook 764 of the second blade lock core 77. Similarly, the tension spring hole 762 of the second blade lock core 77 and the tension spring hook of the third blade lock core 78 fix another tension spring 75, and so on. The three blade lock cores are connected together, and the unlocking holes 766 of the first blade lock core 76, the second blade lock core 77 and the third blade lock core 78 overlap (in the locked state, the unlocking holes 766 partially overlap to form a through hole for the unlocking rod 6 to pass through). The unlocking button 5 includes a pressing portion 51, the pressing portion 51 is connected to a spring 52, the spring 52 is connected to an unlocking rod fixing seat 53, and the unlocking rod fixing seat 53 is connected to an unlocking rod 6. When unlocking, the pressing portion 51 is pressed, thereby causing the spring 52 to be compressed, and causing the unlocking rod 6 to move toward the guide bowl 71.

[0025] When the utility model is working, pressing the pressing part 51 drives the unlocking rod 6 to pass through the through hole 8 and insert into the overlapping part of the unlocking hole 766 (the overlapping part of the three unlocking holes 766 is one through hole. At this time, the three unlocking holes 766 are not concentric. After the unlocking rod 6 is inserted, the three unlocking holes 766 are concentric), thereby driving the first blade lock core 76, the second blade lock core 77 and the third blade lock core 78 to retract (because the three unlocking holes 766 are concentric, the three blade lock cores retract), and the locking part is unlocked. When unlocking at the same time, the baton is swung to make the unlocking rod 6 leave the unlocking hole 766. After that, the three blade lock cores open due to the action of the tension spring 75, and the locking part 763 is stuck in the tube groove 10 to complete the locking.
