Detailed Description

As shown in fig. 1, fig. 2, fig. 3 and fig. 4, a push type retractable push-against device 1 according to an embodiment of the present invention includes a double-push type retractable mechanism 100(push-push button mechanism), a push mechanism 200, a first reset member 300 and a housing 400.

As shown in fig. 1, 2, 3 and 4, the dual-push type telescoping mechanism 100 includes a buckle base 110, an abutting rod 120 and an actuating rod 130. The buckle seat 110 has a first end surface 111 and a second end surface 112 opposite to each other, the push rod 120 and the actuating rod 130 are coaxially disposed on the buckle seat 110, and the push rod 120 protrudes from the first end surface 111 in the extending direction Y, and the actuating rod 130 protrudes from the second end surface 112. The actuating rod 130 is used to be repeatedly pressed along the extending direction Y, so that the push rod 120 moves between a protruding position P protruding from the first end surface 111 and a retracted position R retracted into the buckle base 110.

As shown in fig. 1, 2, 3 and 4, the pressing mechanism 200 includes a pressing lever 210, a cam member 220 and a steering unit 230. The pressing lever 210 is movably disposed along the pressing direction X, and the pressing direction X and the stretching direction Y form an included angle therebetween. Specifically, the pressing direction X and the extending/contracting direction Y may be arranged at an angle of 90 degrees, but other angles are not excluded.

Referring to fig. 5, 6 and 7, the cam member 220 is connected to the steering unit 230. The turning unit 230 is coupled to the pressing rod 210, and the cam member 220 has an apex 221 distant from the pressing rod 210. As shown in fig. 5 and 6, the steering unit 230 is configured such that when one pressing end 212 of the pressing rod 210 is pressed toward the cam member 220 along the pressing direction X, the steering unit 230 drives the cam member 220 to rotate according to the pressing direction X, and moves the vertex 221 to the telescopic direction Y to press the actuating rod 130. At this time, the actuating rod 130 is pressed to drive the push rod 120 to move, so that the push rod 120 moves from the retracted position R to the protruding position P.

As shown in fig. 4 and 7, the first restoring element 300 may be a compression spring, which is sleeved on the pressing rod 210, and two ends of the first restoring element 300 respectively push against the inner walls of the pressing rod 21 and the housing 400. The first returning member 300 serves to normally provide a pushing force to move the pressing lever 210 away from the cam member 220 in the pressing direction X. When the pressing force to the pressing lever 210 is removed as shown in fig. 7, the pressing lever 210 is moved away from the cam member 220 in the pressing direction X by the urging force of the first restoring member 300 to drive the cam member 220 to rotate reversely by the turning unit 230, and the moving peak 221 is restored from the expansion and contraction direction Y to the state before the pressing lever 210 is pressed. At this time, the push rod 120 is maintained at the protruding position P by the action of the double push type retracting mechanism 100.

As shown in fig. 1, 2, 4 and 8, the housing 400 has a top surface 410 and a side surface 420. The side surface 420 is perpendicular to the top surface 410, the top surface 410 is provided with a first through hole 411, and the side surface 420 is provided with a second through hole 422. The double-push type telescoping mechanism 100 and the pressing mechanism 200 are fixed in the housing 400, the push rod 120 passes through the first through hole 411 and protrudes out of the top surface 410, and the pressing rod 210 passes through the second through hole 422 and protrudes out of the side surface 420. In addition, the second through hole 422 and the pressing rod 210 have a non-circular cross section and are matched with each other such that the pressing rod 210 does not rotate in the second through hole 422. The second through hole 422 guides the pressing rod 210 such that the pressing rod 210 moves linearly along the pressing direction X without rotating according to the pressing direction X when being pressed.

As shown in fig. 4 and 8, the housing 400 further includes an upper housing 401 and a lower housing 402. The upper housing 401 is used for accommodating the fastening seat 110, and the first through hole 411 is formed in the upper housing 401, such that a portion of the upper housing 401 overlapping the first end surface 111 forms a stopping portion 401a, and the second end surface 112 is exposed on the bottom surface 401b of the upper housing 401. The lower case 402 is coupled to the bottom surface 401b of the upper case 401 such that the pressing end 131 of the actuating lever 130 is located in the lower case 402. The pressing mechanism 200 and the first restoring member 300 are disposed in the lower housing 402, and the second through hole 422 is disposed in the lower housing 402. The pressing end 212 of the pressing rod 210 protrudes out of the lower housing 402 through the second through hole 422, and the first restoring member 300 is pressed between the pressing rod 210 and the inner wall of the lower housing 402 along the pressing direction X.

As shown in fig. 9 and 10, the steering unit 230 may be a rack and pinion combination, a rotary sleeve mechanism, or the like. In one embodiment, the steering unit 230 is a rotating sleeve mechanism, and the steering unit 230 includes a tab 231 and a rotating sleeve 232. The projection 231 is provided on the outer circumferential surface of the pressing rod 210, and linearly moves parallel to the pressing direction X as the pressing rod 210 moves. Since the non-circular cross-section of the second through hole 422 and the pressing rod 210 can limit the rotation of the pressing rod 210, the protrusion 231 does not move in the tangential direction of the outer circumferential surface of the pressing rod 210.

With reference to fig. 5, 6, 9 and 10, the rotating sleeve 232 is sleeved on the pressing rod 210, the cam member 220 is disposed on the outer circumferential surface of the rotating sleeve 232, and the swinging center of the cam member 220 and the axial center of the rotating sleeve 232 are coaxially disposed. The rotating sleeve 232 further includes a guide groove 233, and the guide groove 233 is opened on the outer circumferential surface of the rotating sleeve 232 substantially along a spiral path and communicates with the inside of the rotating sleeve 232. The protrusion 231 is slidably disposed in the guiding groove 233, so that when the protrusion 231 linearly moves parallel to the pressing direction X, the rotating sleeve 232 is driven to rotate according to the pressing direction X.

As shown in fig. 5, 6, 9 and 10, the guide groove 233 has a first end 233a and a second end 233 b. The first end 233a extends toward the pressing end 212 of the pressing rod 210 in the axial direction of the rotation sleeve 232, and the second end 233b extends toward the cam member 220 in the axial direction of the rotation sleeve 232. On the circumference of the outer circumferential surface of the rotating sleeve 232, the distance from the first end 233a to the junction of the rotating sleeve 232 and the cam member 220 is greater than the distance from the second end 233b to the junction; preferably, the second end 233b is located substantially at the junction of the rotating sleeve 232 and the cam member 220. The cam member 220 is approached on the circumference of the outer peripheral surface of the rotating sleeve 232. When the protrusion 231 is located at the second end 233b, the protrusion 231 drives the cam member 220 to rotate, and moves the vertex 221 to the telescopic direction Y to press the actuating rod 130. Since the rotating sleeve 232 is disposed in the lower housing 402, the first end 233a can extend to the end of the rotating sleeve 232 to form an open state, so that the pressing rod 210 and the protrusion 231 can be conveniently mounted. As shown in fig. 8, the inner wall surface of the lower housing 402 can be stopped at the first end 233a in the open state to prevent the bump 231 from falling out of the first end 233 a.

As shown in fig. 6, when the pressing end 212 of the pressing lever 210 is pressed toward the cam member 220 in the pressing direction X, the projection 231 linearly moves parallel to the pressing direction X to drive the cam member 220 to rotate. As the cam member 220 rotates and the projection 231 moves, the projection 231 reaches the second end 233b, so that the peak 221 moves in the telescopic direction Y to press the actuating rod 130.

As shown in fig. 7, the pressing force to the pressing lever 210 is removed, the pressing lever 210 is moved away from the cam member 220 in the pressing direction X by the urging force of the first restoring member 300, and the cam member 220 is driven to rotate reversely by the projection 231. As the cam member 220 rotates and the projection 231 moves, the projection 231 reaches the first end 233a, and the apex 221 is restored to the state before the pressing lever 210 is pressed out of the expansion and contraction direction Y.

Referring to fig. 4 and 11, in one embodiment, the buckle base 110 has a through hole 113 connecting the first end surface 111 and the second end surface 112. A stop portion 401a is disposed on the first end surface 111, the stop portion 401a has a first through hole 411, and the first through hole 411 overlaps the through hole 113. The stopping portion 401a can be a part of the upper shell 401, that is, the first through hole 411 of the stopping portion 401a is the first through hole 411 of the upper shell 401.

As shown in fig. 4, 12 and 13, the through hole 113 is divided into an engaging section 113a close to the second end surface 112 and a movable section 113b close to the first end surface 111, the cross section of the movable section 113b is larger than that of the engaging section 113a, a step 113c is formed between the movable section 113b and the engaging section 113a, and the cross section of the first through hole 411 is smaller than that of the movable section 113 b.

As shown in fig. 11, 12 and 13, the abutting rod 120 has an abutting end 121 and an opposite first rotating engagement surface 122. The abutting end 121 is used for passing through the first through hole 411. The first rotating engagement surface 122 is provided corresponding to the stepped portion 113c, the first rotating engagement surface 122 has a plurality of first sliders 123 protruding in the radial direction of the abutting rod 120, the plurality of first sliders 123 are arranged at intervals, and the plurality of first sliders 123 protrude from the first rotating engagement surface 122. The second restoring member 140 is disposed between the stopping portion 401a and the abutting rod 120 to push the abutting rod 120 toward the step portion 113 c. The second restoring member 140 may be a compression spring, and is sleeved on the pushing rod 120.

As shown in fig. 12 and 13, the actuating rod 130 has a pressed end 131 and an opposite second rotating engagement surface 132. The actuating rod 130 protrudes from the second end face 112. The second rotating engagement surface 132 has a plurality of second sliders 133 protruding in a radial direction of the actuating rod 130, the plurality of second sliders 133 are arranged at intervals, and each of the second sliders 133 is slidably positioned in one of the plurality of sliding grooves 113 d.

Fig. 14, 15 and 16 omit the drawing of the second restoring member 140, and the downward arrow S indicates the pushing force of the second restoring member 140 on the pushing rod 120. Defining a forward torque direction T around the extension/retraction direction, the first rotating engagement surface 122 and the second rotating engagement surface 132 each have a plurality of inclined surfaces arranged at intervals, and the plurality of inclined surfaces extend along the forward torque direction T and incline toward the pressed end 131, when the actuating rod 130 moves toward the pushing/abutting rod 120 to compress the second restoring member 140 to generate a thrust, the inclined surfaces of the first rotating engagement surface 122 and the second rotating engagement surface 132 contact each other and slide relative to each other, so that the inclined surface of the first rotating engagement surface 122 can slide relative to the inclined surface of the second rotating engagement surface 132, and the pushing/abutting rod 120 is driven to rotate along the forward torque direction T to enable each first slider 123 to be inserted into each sliding groove 113d or each engaging groove 113e, so as to push or retract the pushing/abutting rod 120.

As shown in fig. 12, 13 and 14, each card slot 113e has a first inclined surface 113e1 extending along the forward torque direction T and inclined toward the pressure receiving end 131, and compared with the second end surface 112, a second inclined surface 113e2 higher than the first inclined surface 113e1 is provided between each card slot 113e and an adjacent one of the sliding chutes 113d and inclined toward the adjacent sliding chute 113 d.

When the actuating rod 130 is pressed to press the second rotating engagement surface 132 against the first rotating engagement surface 122, the corresponding second slider 133 of each first slider 123 contacts the first slider 123 with the corresponding tooth 1321 thereof, so that the first guide surface 1231 and the second guide surface 1322 slide relative to each other, and a torque in the forward torque direction T is generated on the abutting rod 120. When the first slider 123 is disengaged from the sliding slot 113d, the torque causes the first slider 123 to enter the adjacent card slot 113e through the guidance of the first inclined surface 113e 1.

As shown in fig. 16, when the pressing of the actuating lever 130 is stopped, the first slider 123 slides along the first inclined surface 113e1 to engage with the engaging groove 113e, so that the pushing rod 120 moves to the protruding position P.

As shown in fig. 17, when the actuating lever 130 is pressed again to make the first slider 123 higher than the second inclined surface 113e2, the torque moves the first slider 123 toward the next sliding slot 113d along the forward torque direction T. When the pressing of the actuating lever 130 is stopped, the first slider 123 is guided by the second inclined surface 113e2 to enter the next sliding slot 113d, and the state shown in fig. 14 is formed, so that the push rod 120 retracts to the retracted position R.
