Description

TECHNICAL FIELD

[0001] The main technical features of the guide groove pressing device of the present application, which is applied to the field of crossbow, are that it can be installed on the sighting seat of the crossbow to provide a constant rated pressure to press against the arrow shaft, so as to avoid affecting the speed and accuracy of the crossbow after firing, and it can be adjusted in different high and low positions according to the height of the arrow shaft installed in the guide groove, and the pressing force on the arrow shaft will not change, which is a very practical invention. BACKGROUND

[0002] The crossbow is a kind of cold weapon that does not need to use gunpowder propulsion, and it has been improved for a long time. Its performance development in various uses has been quite mature. For example, the US patent No. US9417029B1, the body of the crossbow is formed with a guide groove on the side opposite to the bowstring, and the outer section of the guide groove is provided with a firing seat, and the firing seat is combined with a sighting seat located above the guide groove and facing the body of the crossbow.

[0003] The guide sleeve can be directly installed on the end of the sighting seat of the body of the crossbow without disassembling any part of the crossbow, and the elastic member elastically pushes the pressing rod, so that the small diameter section of the pressing rod passes through the guide sleeve to press the arrow shaft, so as to prevent the arrow shaft from slipping out of the guide groove and causing trouble.

[0004] However, the position of the guide sleeve installed on the sighting seat is fixed, and the height of the pressing rod towards the guide groove is fixed, which will form different pressing forces due to the different heights of the arrow shaft installed in the guide groove. Therefore, during the firing process of the crossbow, the excessive pressing force of the pressing rod on the arrow shaft will cause the arrow shaft to be unable to be shot out at the best speed, thereby affecting the speed. Moreover, when the arrow shaft is shot out under the excessive pressure of the pressing rod at the end of the arrow shaft, the end of the arrow shaft will be affected by the pressing force, causing the front end of the arrow shaft to be slightly inclined and deviated from the center.

[0005] Therefore, relevant manufacturers must think about how to improve it to maintain a certain pressing force on the arrow shaft to avoid affecting the speed and accuracy of the crossbow after firing. SUMMARY

[0006] The main technical problem to be solved by the present application is to overcome the above-mentioned defects existing in the prior art, and to provide a guide groove pressing device of a crossbow, which is installed on the sighting seat of the body of the crossbow and relative to the position of the guide groove, to provide the arrow shaft installed in the guide groove with pressing and fixing, and to flexibly adjust the pressing position according to the different thickness and size of the arrow shaft installed in the guide groove, without changing the pressing force on the arrow shaft, so as to maintain a fixed rated pressure to press against the arrow shaft, effectively avoid affecting the speed and accuracy of the crossbow after firing, and indeed have progress in use.

[0064] Please refer to Figures 1-13 The present application is a guide slot pressing device for a bow, which has two embodiments. The first embodiment, as shown in Figures 1-7 includes:

[0065] A bow body 10 has a guide slot 12 and a sighting seat 11 opposite the guide slot 12.

[0066] A fixing frame 20 is provided to be combined with the sighting seat 11 and opposite the guide slot 12.

[0067] A pressing seat 40 has a sleeve hole 41 with a lower hole opening 411 facing the guide slot 12 and an upper end wall 412 at the opposite end, an elastic member 42 sleeved in the sleeve hole 41, and a pressing member 43.

[0068] A plurality of limiting screws 30 each has an outer threaded section 31, a driving head 32, and a spring 33 sleeved in the outer threaded section 31, the plurality of limiting screws 30 are threaded through the pressing seat 40 and screwed to the bottom surface of the fixing frame 20, and the pressing seat 40 is elastically abutted against the bottom surface of the fixing frame 20 by the elastic member 42 and the spring 33 sleeved in the outer threaded section 31 of each limiting screw 30; and

[0069] An adjusting screw 50 is threaded through the fixing frame 20 corresponding to the position of the pressing seat 40, and the adjusting screw 50 is screwed in and out of the end of the fixing frame 20 to push the pressing seat 40 to ascend and descend along the plurality of limiting screws 30 in the axial direction.

[0070] Further details of the embodiments, use effects, and use efficiency of the present application are described in the following. The pressing seat 40 is threaded through and screwed to the bottom surface of the fixing frame 20 opposite the guide slot 12 of the bow body 10, and the pressing seat 40 is elastically abutted against the bottom surface of the fixing frame 20 by the elastic member 42 and the spring 33 sleeved in the outer threaded section 31 of each limiting screw 30. As shown in Figure 5 , the pressing seat 40 is pushed by the elastic member 42 to make the pressing member 43 partially protrude from the lower hole opening 411, so as to provide the pressing and fixing of the arrow shaft 13 loaded in the guide slot 12, and prevent the arrow shaft 13 from slipping out and causing the trouble of reinstallation.

[0071] In addition, as shown in Figure 6 , Figure 7 , when the arrow shaft 13 loaded in the guide slot 12 cannot be pressed and fixed by the pressing member 43 protruding from the lower hole opening 411 due to the different sizes, the adjusting screw 50 is screwed in and out of the end of the fixing frame 20 to push the pressing seat 40 to descend along the plurality of limiting screws 30 in the axial direction (as shown by the arrow in the figure), so as to adjust the displacement of the pressing seat 40 and make the pressing member 43 protruding from the lower hole opening 411 to press and fix the arrow shaft 13. Figure 7

[0072] ​Furthermore, since the resilient distance of the upper end wall 412 of the sleeve hole 41 to the pressing member 43 is fixed, the pressing member 43 can only press against the arrow shaft 13 in the protruding part of the lower hole 411, and a fixed size of rated pressure can be formed when the arrow shaft 13 is pressed. Therefore, after the pressing base 40 is axially displaced along the plurality of limiting screws 30, the pressing force of the pressing member 43 on the arrow shaft 13 will not change, and the arrow shaft 13 can be maintained at a fixed pressure, effectively avoiding the influence of the excessive pressing force on the shooting speed and accuracy after firing, and indeed having progress in use.

[0073] The features of each component of the present application are further described below. In the above Figures 1-2 description, the pressing base 40 has a plurality of through holes 44 that accommodate the plurality of limiting screws 30, and each through hole 44 has a large diameter step groove 441 that accommodates the spring 33. Therefore, when the pressing base 40 is pushed by the adjusting screw 50 to adjust the axial lifting of the plurality of through holes 44 along the plurality of limiting screws 30, the large diameter step groove 441 provides smooth expansion and contraction of the spring 33, and stable guiding of the lifting displacement adjustment operation of the pressing base 40.

[0074] Secondly, the sleeve hole 41 is located between the plurality of limiting screws 30, and the upper end of the sleeve hole 41 has a stepped groove 413 that accommodates the upper end wall 412, so that the upper end wall 412 is movably combined at the upper end of the sleeve hole 41. Therefore, the upper end wall 412 can be movably detached from the upper end of the sleeve hole 41, and the elastic member 42 and the pressing member 43 can be conveniently inserted into the upper end of the sleeve hole 41 for convenient assembly.

[0075] Furthermore, the pressing member 43 is a steel ball, so that the smooth surface of the steel ball can roll against the installed arrow shaft 13 to reduce frictional wear during the installation operation of the arrow shaft 13.

[0076] In addition, as shown in Figures 8-13 , a second embodiment of the bow guide groove pressing device of the present application comprises:

[0077] A bow body 10 has a guide groove 12 and a sighting base 11 opposite the guide groove 12.

[0078] A fixed frame 20 is provided to be combined with the sighting base 11 and opposite the guide groove 12.

[0079] A fixed screw 60 is screwed through the fixed frame 20 and has an external thread segment 61 protruding towards the guide groove 12. and

[0080] A top pressing sleeve 70 has a lower sleeve groove 71 axially recessed at both ends, an upper screw hole 72, and a second elastic member 73 and a second pressing member 74 accommodated in the lower sleeve groove 71. The lower sleeve groove 71 has a lower groove opening 711 facing the guide groove 12 and an upper groove wall at the opposite end. The second elastic member 73 is elastically abutted at both ends against the upper groove wall and the second pressing member 74, and the second pressing member 74 is partially protruded out of the lower groove opening 711. The upper screw hole 72 is screwed with the outer threaded section 61, and the top pressing sleeve 70 is axially raised and lowered along the outer threaded section 61 by screwing and unscrewing.

[0081] As shown in Figure 11 , the second elastic member 73 of the top pressing sleeve 70 pushes the second pressing member 74 partially protruded out of the lower groove opening 711 to provide the pressing and fixing of the arrow shaft 13 installed in the guide groove 12, preventing the arrow shaft 13 from slipping out and causing the trouble of reinstallation.

[0082] In addition, as shown in Figure 12 , Figure 13 , when the arrow shaft 13 installed in the guide groove 12 cannot be pressed and fixed by the second pressing member 74 protruded out of the lower groove opening 711 due to the difference in size, the top pressing sleeve 70 is rotated, and the screwing and unscrewing of the upper screw hole 72 relative to the outer threaded section 61 causes the top pressing sleeve 70 to be axially lowered (as shown by the arrow in the figure) along the outer threaded section 61 to adjust the displacement, so that the second pressing member 74 protruded out of the lower groove opening 711 can press and fix the arrow shaft 13. Figure 13

[0083] Furthermore, since the abutting distance of the upper groove wall of the lower sleeve groove 71 to the second pressing member 74 is fixed, the second pressing member 74 can only press the arrow shaft 13 with the part protruded out of the lower groove opening 711, so that a fixed size of rated pressure can be formed when the arrow shaft 13 is pressed, effectively avoiding the influence on the shooting speed and accuracy after firing due to the excessive pressure of pressing the arrow shaft 13, and truly having the progress in use.

[0084] Moreover, the fixing frame 20 further has an outer ring groove 21 recessed in the circumferential side of the outer threaded section 61, and the outer ring groove 21 is opposite to the upper end of the top pressing sleeve 70 and larger than the upper end of the top pressing sleeve 70; therefore, the top pressing sleeve 70 can enter the outer ring groove 21 when being upwardly adjusted, and further provides more upward adjustment space for the axial raising and lowering adjustment operation of the top pressing sleeve 70.

[0085] Finally, the second pressing member 74 is a steel ball, so that the smooth surface of the steel ball can roll relative to the installed arrow shaft 13 to reduce the friction loss during the installation operation of the arrow shaft 13.

[0086] ​The above is only the preferred embodiment of the present application, and does not limit the present application in any form. Any simple modification, equivalent change and modification of the above embodiment according to the technical essence of the present application are still within the scope of the technical solution of the present application.
