Description

Technical Field

[0001] This utility model belongs to the field of crossbow technology, specifically a positioning device for keeping the crossbow trigger safety in the open and closed positions. Background Technology

[0002] A crossbow is a bow with a crossbow lance attached, and uses a separate trigger mechanism to keep the bowstring in a stretched state. The trigger mechanism can be integrated into the crossbow lance or used separately. The crossbow trigger mechanism mainly includes a bowstring catch for holding the bowstring, a trigger catch for opening the bowstring catch to release the bowstring, and a safety to prevent accidental discharge. These three main components, along with other parts, work together to form the trigger mechanism.

[0003] As a safety device to prevent accidental discharge, the safety device needs to be fixed in its open or closed position, with a clear location and no room for movement. The existing trigger structure has a certain degree of wobbling, which can affect the user's misjudgment of the trigger safety position and cause doubts about the trigger's safety. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a positioning device for the safety of a crossbow trigger.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A positioning device for a crossbow trigger safety includes a housing and a bowstring latch, a trigger block, a trigger safety, a safety connector, and a positioning component disposed within the housing. The bowstring latch, trigger block, and trigger safety are hinged to the housing. A limiting groove is provided within the housing. The bowstring latch is connected to a latch retaining spring, and the trigger block is connected to a trigger retaining spring. Both the latch retaining spring and the trigger retaining spring are mounted to the housing. A locking position is provided on the trigger block to restrict contact of the bowstring latch when it is in the closed state. The trigger block and the safety connector are hinged to the housing via the same trigger pivot. The positioning component is connected to the safety connector, and the safety connector is in contact with the trigger safety. The positioning component is movably disposed within the limiting groove. During the rotation of the trigger safety, the positioning component moves within the limiting groove via the safety connector. The positioning component is used to position and limit the trigger safety.

[0007] As a further improvement, the positioning assembly includes a transfer component, a positioning spring, and a positioning component located within the limiting groove. The transfer component is rotatably connected to the safety connector, and one end of the positioning spring is connected to the transfer component and the other end is connected to the positioning component.

[0008] As a further improvement, the inner wall of the limiting groove has a first rounded corner area, a second rounded corner area and a third rounded corner area, and the transfer component and the positioning component are located in different rounded corner areas during the movement.

[0009] As a further improvement, the trigger safety includes a bracket and a safety ear. A safety ear is provided on each side of the bracket. The safety ear is located on both sides of the outer shell and is used for external force to push. A safety cross shaft is provided in the middle of the bracket for contact and limiting with the bowstring latch. A safety cross beam is provided at the bottom of the bracket for contact and limiting with the trigger block.

[0010] As a further improvement, a safety groove is provided on one side of the bracket, and a first convex shaft is provided on the safety connector, which is inserted into the safety groove.

[0011] As a further improvement, the safety connector is provided with a second convex shaft, which is rotatably mounted with the transfer component.

[0012] As a further improvement, one end of the transfer component is set as a circumferential surface, and one end of the positioning component is set as a circumferential surface. One end of the circumferential surface of the transfer component and the positioning component is in contact with the inner wall of the limiting slide groove.

[0013] As a further improvement, the bracket is provided with two spaced protrusions, and a safety groove is formed between the two protrusions.

[0014] Compared with the prior art, the present invention has the following beneficial technical effects:

[0015] Through the cooperation between the trigger safety, safety connector, intermediate component, and positioning component, the trigger safety needs to overcome the tension of the positioning spring during rotation in order to switch the safety state. The safety does not have problems such as wobbling or free change of position. The overall structure is simple and the structural position is concealed, which improves the overall reliability of the trigger. Attached Figure Description

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0026] like Figure 1-5As shown, a crossbow trigger safety positioning device includes a housing 1, a bowstring latch 2, a trigger safety 4, a trigger block 3, a safety connector 5, and a positioning assembly. The housing 1 is used to install the various parts. The bowstring latch 2, the trigger safety 4, and the trigger block 3 are respectively hinged to the housing 1.

[0027] The housing 1 has a limiting groove 10 inside. The bowstring latch 2 is connected to a latch retaining spring 201. The trigger block 3 is connected to a trigger retaining spring 301. Both the latch retaining spring 201 and the trigger retaining spring 301 are mounted to the housing. The trigger block 3 has a locking position 9, which is used to limit the contact of the bowstring latch 2 when it is closed. The trigger block 3 and the safety connector 5 are hinged to the housing 1 through the same trigger pivot 302. The positioning component is connected to the safety connector 5. The safety connector 5 is in contact with the trigger safety 4. The positioning component is movably located in the limiting groove 10. During the rotation of the trigger safety 4, the positioning component is moved within the limiting groove 10 through the safety connector. The positioning component is used to position and limit the trigger safety. The retaining spring 201 is used to restrict the bowstring retainer 2, so that the bowstring retainer 2 remains open when not in use, preventing the bowstring retainer from freely shaking and closing during stringing, and preventing the bowstring from smoothly entering the trigger; the trigger retaining spring 301 is used to restrict the trigger block 3, so that the trigger block 3 remains closed with other components when not subjected to external force.

[0028] The bowstring latch 2 is used to hook the bowstring. The bottom of the bowstring latch 2 contacts the trigger block 3 through the locking position 9. When the trigger block 3 rotates, it drives the locking position 9 to move, thereby removing the restriction on the bowstring latch 2 and releasing the bowstring.

[0029] The positioning assembly includes a transfer component 6, a positioning spring 7, and a positioning component 8 located within the limiting slide groove 10. The transfer component 6 is rotatably connected to the safety connector 5, and one end of the positioning spring 7 is connected to the transfer component 6 and the other end is connected to the positioning component 8.

[0030] like Figure 3 As shown, the trigger safety 4 is installed behind the bowstring latch 2. The trigger safety structure is as follows: Figure 4As shown, the trigger safety 4 includes a bracket with two safety lugs 401 on the top. These lugs 401 are exposed on both sides of the outer casing for manual opening or closing of the safety. The trigger safety 4 has a safety cross shaft 405 in the middle. During stringing, the bowstring latch 2 is rotated by the bowstring. As the bowstring latch 2 rotates, its rear end contacts the safety cross shaft 405, causing the trigger safety 4 to rotate and return to the closed state. The trigger safety 4 also has a safety shaft hole 402 in the middle, which is hinged to the casing 1 via a shaft. Two protrusions 403 are spaced apart on one side of the middle of the trigger safety 4, forming a safety groove 404 between them. This groove connects to the safety connector 5. The trigger safety 4 has a safety beam 406 at the bottom, which contacts the trigger block 3. The trigger block 3 passes between the safety cross shaft 405 and the safety beam 406. When the safety is off, the bottom of the trigger block 3 contacts the upper part of the safety beam 406, restricting the rotation of the trigger block 3, thereby restricting the firing of the bowstring.

[0031] The safety connector 5 and the trigger block 3 are mounted together on a trigger shaft 302 and pivot. The front end of the safety connector 5 has a first convex shaft 501, which is used to connect to the safety groove 404 on the safety and slide on the safety groove 404. When the safety trigger 4 rotates, the first convex shaft 501 is driven to rotate by the push of the safety groove 404. The rear end of the safety connector 5 has a second convex shaft 502, which is used to connect to the transfer component 6.

[0032] The transfer component 6 has a shaft hole, which is connected to the second convex shaft 502. The inner wall of the limiting slide groove 10 has a first rounded corner area 101, a second rounded corner area 102 and a third rounded corner area 103. The transfer component 6 and the positioning component 8 are located in different rounded corner areas during the movement.

[0033] refer to Figure 2 and Figure 5 The diagram shows the changes in the state of each component during the use of this utility model.

[0034] During the winding process, if the trigger safety 4 is in the open state, after the bowstring contacts the front wall of the bowstring latch 2, it drives the bowstring latch 2 to rotate. The rear end of the bowstring latch 2 touches the safety horizontal axis 405, which drives the trigger safety 4 to rotate, thus completing the winding action.

[0035] At this time, the trigger is in the following state: the bowstring latch 2 hooks the bowstring, the trigger block 3 holds the bottom of the bowstring latch 2 to prevent the bowstring latch 2 from releasing the bowstring, the trigger safety 3 is in the closed state, and the safety beam 406 holds the bottom of the trigger block 3 to restrict the rotation of the trigger block 3.

[0036] The slide groove 404 on the trigger safety, together with the safety connector 5, the intermediate component 6, the positioning spring 7, and the positioning component 8, forms a limiting structure. Due to the spring force, the intermediate component 6 is pressed against the first rounded corner area 101 on the limiting slide groove 10, and the positioning component 8 slides on the third rounded corner area 103. At this time, the trigger safety 4 cannot rotate freely. If you want to open the trigger safety 4, you need to overcome the elastic force of the positioning spring 7. This force is determined by the magnitude of the elastic force of the positioning spring 7.

[0037] When trigger safety 4 is engaged, move safety lug 401 forward; trigger safety 4 will rotate counterclockwise. Figure 3 As shown, the safety connector 5 is rotated clockwise by the safety slide 404. The second convex shaft 502 on the safety connector 5 drives the intermediate component 6 to rotate downward. The positioning spring 7 between the intermediate component 6 and the positioning component 8 is compressed, reducing the gap between them. Then, the intermediate component 6 slides into the second rounded corner area 102 on the limiting slide 10, and the positioning component 8 is located in the third rounded corner area 103. This completes the switch of the trigger from closed to open.

[0038] It should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
