[0041] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Example

[0043] The present invention will be further described below in conjunction with the accompanying drawings.

[0044] like Figures 3 to 7 As shown, the present embodiment provides a push-type watchband quick-release structure, including a shell 10 embedded and installed on the watchband, the shell 10 is clamped between a pair of lugs 12 of the watch case 11, and the shell 10 is symmetrically provided with limit blocks 13 integrally formed on the shell 10 to adapt to the recessed position on the back of the lug 12, and the adjacent side surfaces of the shell 10 are respectively provided with a block assembly 15 for engaging the anti-retraction inclined groove 14 of the watch case 11 and a pressing assembly 16 for driving the block assembly 15 to move, and the pressing assembly 16 includes a pair of cylindrical springs 17 located in the shell 10 and used for resetting the block assembly 15.

[0045] The working principle and beneficial effects of the above technical solution are:

[0046] The present invention discloses a push-type watchband quick-release structure. Under the cooperation of the limit plug 13 and the concave position, the housing 10 is clamped between a pair of lugs 12, and the clamping block assembly 15 moves against the surface of the watch case 11. After walking to the position of the anti-retraction inclined groove 14, under the action of the cylindrical spring 17, the clamping block assembly 15 is reset and clamped in the anti-retraction inclined groove 14. When the watchband needs to be removed, after the pressing assembly 16 is manually pressed, the cylindrical spring 17 shrinks, and the clamping block assembly 15 retracts into the housing 10 to release the connection with the anti-retraction inclined groove 14, and the housing 10 is reversely pulled out from between the pair of lugs 12. The present invention provides a push-type watchband quick-release structure. The pressing assembly 16 and the clamping block assembly 15 are compactly installed in the housing 10, and the assembly is precise. The cylindrical spring 17, which is the core component for resetting the clamping block assembly 15, is hidden in the housing 10. Because it is not exposed to the outside, the aesthetics is improved. At the same time, the cylindrical spring 17 will not be corroded by sweat, and the watch will not fall off.

[0047] In one embodiment, the block assembly 15 includes:

[0048] A side opening 18, the side opening 18 is opened at the end of the housing 10 close to the watch case 11;

[0049] A lower transverse groove 19, which is provided at the bottom of the housing 10 near the side opening 18;

[0050] The L-shaped fastener 20 is arranged in a vertically bent shape. The L-shaped fastener 20 is located at the side opening 18. One end of the L-shaped fastener 20 is rotatably installed in the lower horizontal groove 19 through the side rotating shaft 21. The other end of the L-shaped fastener 20 extends into the shell 10. The pressing assembly 16 and the cylindrical spring 17 are arranged one above and one below on the other end of the L-shaped fastener 20. The bent section of the L-shaped fastener 20 extends out of the side opening 18 to adapt to the anti-retreat inclined groove 14.

[0051] The working principle and beneficial effects of the above technical solution are:

[0052] With the cooperation of the limiting plug 13 and the concave position, the housing 10 is clamped between the pair of lugs 12, and because the housing 10 moves close to the side opening 18 and against the surface of the watch case 11, the bent section of the L-shaped clip 20 is pushed and retracted from the side opening 18 into the housing 10, and as the housing 10 continues to slide down, after the L-shaped clip 20 moves to the position of the stop-retract chute 14, the L-shaped clip 20 loses its pushing force, and under the reset of the cylindrical spring 17, the bent section of the L-shaped clip 20 is clamped in the stop-retract chute 14, thereby completing the fixing of the housing 10 between the pair of lugs 12. When removing the watch strap, after manually pressing the pressing assembly 16, the cylindrical spring 17 contracts, and the L-shaped clip 20 rotates in the direction of retracting into the housing 10 with the side shaft 21 as the center, and the L-shaped clip 20 is disconnected from the stop-retract chute 14, and the housing 10 is pulled out from between the pair of lugs 12 in the reverse direction.

[0053] In one embodiment, the pressing assembly 16 includes:

[0054] The cover plate 22 is embedded and installed on the housing 10. The bottom end of the cover plate 22 is integrally formed with side support blocks 23 symmetrically provided. The L-shaped buckle 20 is located between the two side support blocks 23. The two side support blocks 23 are pressed one by one on the lower transverse grooves 19 at the two shaft ends close to the side shaft 21;

[0055] The button 24 is embedded in the center of the cover plate 22 . The button 24 abuts against the L-shaped buckle 20 and is arranged above and below the cylindrical spring 17 .

[0056] The working principle and beneficial effects of the above technical solution are:

[0057] The cover plate has a side support block 23 end which is clamped in the shell body 10 along the side opening 18. The L-shaped fastener 20 is located between the two side support blocks 23 to limit the L-shaped fastener 20 and prevent it from shaking, thereby achieving precise movement of the L-shaped fastener 20. After manually pressing the button 24 on the cover plate 22, the cylindrical spring 17 contracts, and the L-shaped fastener 20 rotates in the direction of retracting into the shell body 10 with the side shaft 21 as the center, thereby releasing the connection between the L-shaped fastener 20 and the anti-retraction inclined groove 14.

[0058] In one embodiment, the cover plate 22 is fastened to the housing 10 by screws 25 .

[0059] like Figures 8 to 10 As shown, this embodiment further provides an assembly process of a push-type watchband quick-release mechanism, which is applied to the above-mentioned push-type watchband quick-release structure, including:

[0060] Step 1: Install the upper housing 10 of the jig, put a pair of cylindrical springs 17 into the bottom of the housing 10, and insert the end of the L-shaped clip 20 with the side shaft 21 into the lower transverse groove 19 in the vertical direction to ensure that the wedge-shaped portion of the L-shaped clip 20 protrudes out of the side opening 18. After the L-shaped clip 20 presses the cylindrical spring 17, the L-shaped clip 20 is kept stationary;

[0061] Step 2: The center end of the cover plate 22 is provided with a mounting opening, and the button 24 is mounted on the mounting opening. The end of the cover plate 22 with the side support block 23 is inserted into the bottom of the housing 10 along the side opening 18, and the side support block 23 avoids the L-shaped fastener 20 during the process, and the button 24 and the round spring 17 press the L-shaped fastener 20 one above and one below to be assembled in place;

[0062] Step 3: Symmetrically arranged mounting holes are reserved on the cover plate 22 , screws 25 are passed through the mounting holes, and the screws 25 are tightened to fix the cover plate 22 on the housing 10 .

[0063] The working principle and beneficial effects of the above technical solution are:

[0064] After manually fixing the shell 10 on the installation fixture, first place a pair of cylindrical springs 17 into the bottom of the shell 10, then insert the L-shaped clip 20 with the side shaft 21 end into the lower horizontal groove 19 in the vertical direction, and make the L-shaped clip 20 press the circular spring 17 to keep the L-shaped clip 20 stationary, then install the button 24 on the installation port, and insert the cover plate 22 with the side support block 23 end along the side opening 18 into the bottom of the shell 10, and during the process, the side support block 23 avoids the L-shaped clip 20, and the button 24 and the circular spring 17 press the L-shaped clip 20 one above and one below to be assembled in place, and after tightening the screws 25, the assembly of the quick-release structure is completed.

[0065] In one embodiment, installing the fixture in step 1 includes:

[0066] A processing table 26, at the top of which at least three groups of slidable fixing seats 27 are arranged in parallel, and a limiting block 43 for fixing the bayonet 28 at the rear of the housing 10 is installed on the fixing seat 27;

[0067] Front support seats 29, two front support seats 29 are installed in parallel on the top of the processing table 26, front shafts 30 are installed on the two front support seats 29, and the same number of brackets with magnifying glasses 31 are installed on the front shafts 30 as on the fixed seats 27;

[0068] A power motor 32 is installed on one of the front support seats 29 , and an output end of the power motor 32 is connected to the front rotating shaft 30 .

[0069] The working principle and beneficial effects of the above technical solution are:

[0070] The end of the shell 10 with the bayonet 28 is manually clamped on the limit block 43, and the shell 10 is fixed on the fixing seat 27. Then, the end of the L-shaped clip 20 with the side shaft 21 is clamped into the lower horizontal groove 19 in the vertical direction. The fixing seat 27 moves forward in the direction close to the front support seat 29, and the power motor 32 works, thereby driving the front shaft 30 installed at the output end of the power motor 32 to rotate on the front support seat 29. The front shaft 30 drives the bracket with the magnifying glass 31 to rotate. In this way, after the fixing seat 27 stops moving forward, the magnifying glass 31 is just above the shell 10, so that the operator can easily complete the installation of the block assembly 15 and the pressing assembly 16 on the shell 10.

[0071] In one embodiment, the step 1 of installing the fixture further includes:

[0072] Arc-shaped guide frames 33, two arc-shaped guide frames 33 are installed in parallel on the top of the processing table 26, and the arc-shaped rack 34 is slidably sleeved on one end of the arc-shaped guide frames 33;

[0073] The action chamber 35 is located in the processing table 26, and the arc-shaped rack 34 extends into the action chamber 35;

[0074] A transmission rod 36, the top end of the transmission rod 36 is rotatably mounted on the bottom end of the fixed seat 27, and the arc-shaped rack 34 is disposed against the bottom end of the transmission rod 36;

[0075] The gear 37 is mounted on the front shaft 30 , and the gear 37 is meshed with the arc-shaped rack 34 .

[0076] The working principle and beneficial effects of the above technical solution are:

[0077] When the power motor 32 works, thereby driving the bracket with the magnifying glass 31 to rotate, the gear 37 installed on the front rotating shaft 30 rotates synchronously, and the gear 37 drives the arc-shaped rack 34 meshing with it to slide on the arc-shaped guide frame 33, thereby realizing the movement of the arc-shaped rack 34 along an arc-shaped trajectory, and the arc-shaped rack 34 penetrates into the action chamber 35 and presses down the transmission rod 36, and the transmission rod 36 drives the fixed seat 27 connected thereto to slide, so that the fixed seat 27 can move forward in the direction close to the front support seat 29.

[0078] Before the arc-shaped rack 34 is pressed down onto the transmission rod 36 , time is given to manually fix the housing 10 on the plurality of fixing seats 27 in sequence.

[0079] In one embodiment, a limiting rotating shaft 38 is installed in the action chamber 35, a limiting sliding groove 39 is opened on the transmission rod 36, the limiting rotating shaft 38 is slidably connected in the limiting sliding groove 39, one end of the return spring 40 is connected to the end of the transmission rod 36 close to the fixed seat 27, and the other end of the return spring 40 is connected to the inner wall of the action chamber 35.

[0080] The working principle and beneficial effects of the above technical solution are:

[0081] The arc-shaped rack 34 penetrates into the action chamber 35 and presses down the transmission rod 36. The transmission rod 36 rotates around the limit rotating shaft 38, and the transmission rod 36 drives the fixed seat 27 connected thereto to slide. The reset spring 40 is stretched, and the transmission rod 36 gradually penetrates into the action chamber 35 away from the fixed seat 27. When the reset spring 40 is stretched to the maximum, the fixed seat 27 stops moving forward, and the magnifying glass 31 is just above the shell 10. With the help of the magnifying glass 31, after the block assembly 15 and the pressing assembly 16 are installed on the shell 10, the power motor 32 rotates in the opposite direction, and during the process of driving the bracket with the magnifying glass 31 to rotate in the opposite direction, the gear 37 rotates in the opposite direction synchronously. After the arc-shaped rack 34 meshing with the gear 37 releases the downward pressure on the transmission rod 36, the fixed seat 27 retreats and resets under the reset contraction of the reset spring 40. At this time, the installed quick release mechanism is manually removed from the fixed seat 27, and the shell 10 is reinstalled to complete the assembly of the next batch of quick release mechanisms.

[0082] In one embodiment, a pressing strip 41 for temporarily pressing the L-shaped buckle 20 is installed on the inner ring of the arc-shaped rack 34 .

[0083] The working principle and beneficial effects of the above technical solution are:

[0084] When the power motor 32 is working, the bracket with the magnifying glass 31 is driven to rotate. The gear 37 installed on the front rotating shaft 30 rotates synchronously. The gear 37 drives the arc rack 34 meshing with it to slide on the arc guide frame 33, thereby realizing the arc rack 34 to move along the arc track. The arc rack 34 penetrates into the action chamber 35 and presses down the transmission rod 36. The transmission rod 36 drives the fixed seat 27 connected thereto to slide, so that the fixed seat 27 can move forward in the direction close to the front support seat 29, and the pressing bar 41 installed on the inner ring of the arc rack 34 also moves downward synchronously. After the fixed seat 27 stops moving forward, the magnifying glass 31 is just above the shell 10, and synchronously, the pressing bar 41 presses on the L-shaped clip 20 to keep the L-shaped clip 20 stationary, so that the operator can quickly install the block assembly 15 and the pressing assembly 16 on the shell 10 with the help of the magnifying glass 31.

[0085] In one embodiment, a guide slot 42 is provided at the top of the processing table 26 to facilitate the sliding of the bottom end of the fixing seat 27 . The transmission rod 36 extends into the guide slot 42 and is rotatably connected to the bottom end of the fixing seat 27 .

[0086] The beneficial effects of the above technical solution are:

[0087] The provision of the guide slot 42 facilitates the forward and backward movement of the fixing seat 27 .

[0088] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
