- In order to further explain the technical solutions of the present invention, the present invention will be described in detail below with reference to some embodiments.
- A correction tape having a tape guide capable of self-locking after being pushed out is shown in
FIGs. 1-4 , comprising a main body; the main body comprises ahousing 1, atape 2, a rollingapplication mechanism 3, acontrol element 4 and amovable element 5; themovable element 5 comprises atape guide 51; thetape 2 and the rollingapplication mechanism 3 are provided inside thehousing 1; thetape 2 extends across a frontal part of thetape guide 51 and winds around the rollingapplication mechanism 3; thecontrol element 4 controls movement of themovable element 5, and in turns controls extension and retraction of thetape guide 51. In the present invention, thetape 2 and the rollingapplication mechanism 3 are prior arts and will not be described in detail herein. - In the embodiment, the
control element 4 comprises afirst slider 41 and an operating portion; thefirst slider 41 has a cylindrical shape and is a motion transmission element. In the embodiment, the operating portion is arotary knob 42; therotary knob 42 has a shape of a circular cap; thefirst slider 41 has a fixed end and a free end; the fixed end of the first slider is attached to therotary knob 42 at a position proximal to a periphery thereof; thehousing 1 has an elongated shape; one end of thehousing 1 along a lengthwise direction thereof is provided with a tape guide opening 11; thehousing 1 comprises afirst housing section 12 and asecond housing section 13 engageable with each other by the cooperation between grooves and protrusions; therotary knob 42 is rotatably connected with thefirst housing section 12 at an end thereof distal from the tape guide opening 11; therotary knob 42 is provide with anti-slip textured patterns along the periphery thereof to facilitate rotation. - The
movable element 5 is an elongated flattened piece, mounted in between thefirst housing section 12 and thesecond housing section 13; themovable element 5 comprises a tape guide end and adrive end 52; thedrive end 52 is provided with aposition limiting slot 53 at a side wall thereof corresponding to thefirst housing section 12. With reference to acentral axis 54 along a lengthwise direction of themovable element 5 after the correction tape is placed vertically where the lengthwise direction of the correction tape is parallel to a horizontal level, it is observed that the tape guide is positioned at a left side, thedrive end 52 is positioned at a right side, thefirst slider 41 is positioned at a bottom side of thecentral axis 54, and an opposite side with respect to the bottom side of the central axis is an upper side. Directions as will be described below will be referenced according to the directional references as indicated above. - Portions of the
movable element 5 above thecentral axis 54 are considered an upper zone, and portions of the movable element below thecentral axis 54 are considered a bottom zone. Theposition limiting slot 53 is positioned at a right side of themovable element 5. Also, theposition limiting slot 53 is positioned within the bottom zone. Theposition limiting slot 53 is a compound slot comprising afirst slot section 531 and asecond slot section 532 in communication with each other. Thefirst slot section 531 is provided at a side more near to thetape guide 51, and thesecond slot section 532 is provided at a side more distal from thetape guide 51, in other words, thefirst slot section 531 is positioned at a left side of thesecond slot section 532. Thefirst slot section 531 and thesecond slot section 532 are in communication with each other, and both have equal depths. The first slot section 531is a first inclined straight slot that inclines leftward. Thesecond slot section 532 is a vertical straight slot. Both thefirst slot section 531 and thesecond slot section 532 have widths corresponding to a diameter of thefirst slider 41. Thefirst slot section 531 has a stop end, and this stop end is a closed end for stopping and position limiting. Thesecond slot section 532 has an initial end. The stop end is positioned higher than the initial end, in other words, the initial end is located above the initial end. The stop end of theposition limiting slot 53 is a round end preferably corresponding to the cylindrical shape of thefirst slider 41. - A right side of the
first housing section 12 is provided with a guidingslot 16 corresponding to theposition limiting slot 53. The guidingslot 16 is a curved slot comprising an extension end and a retraction end; the retraction end is positioned higher than the extension end, in other words, the retraction end is positioned above the extension end. When the first slider 41is positioned at the initial end and the extension end simultaneously, thetape guide 51 is completely retracted into thehousing 1. When thefirst slider 41 is positioned at the stop end and the retraction end simultaneously, thetape guide 51 is completely extended out of thehousing 1. The guidingslot 16 is positioned at the bottom zone with respect to thecentral axis 54, in other words, both the extension end and the retraction end of the guidingslot 16 are positioned within the bottom zone with respect to thecentral axis 54. An arc of the guiding slot 16 (i.e. the curved slot) has a central angle less than 90 degrees. A range of movement allowed in the guidingslot 16 corresponds to a range of movement between the completely extended position and completely retracted position of thetape guide 51. - A
positioning protrusion 14 is provided respectively on a side wall of the guidingslot 16 at a position near to the extension end and at a position near to the retraction end. Thepositioning protrusion 14 is made of plastic material and is slightly resilient. - The
first slider 41 passes through firstly the guidingslot 16 and then theposition limiting slot 53; by means of the guiding function of the guidingslot 16 and through the cooperation with the position limiting slot, thefirst slider 41 drives themovable element 5 to move and thus achieves extension and retraction of thetape guide 51. Thefirst slider 41 is positioned or movable within theposition limiting slot 53. Consider a condition where thetape guide 51 is completely retracted into thehousing 1 as an initial condition; in such initial condition, thefirst slider 41 is positioned at the extension end of the guidingslot 16, and the free end of thefirst slider 41 is limited within thesecond slot section 532 of theposition limiting slot 53. Thepositioning protrusion 14 near the extension end can prevent therotary knob 42 from driving and sliding thefirst slider 41 causing movement of themovable element 5 or even extension of thetape guide 51. - With reference to the positioning of the correction tape as shown in
FIG. 1 , and consider a condition of thetape guide 51 completely retracted in thehousing 1 as an initial condition; when it is required to extend the tape guide, rotate therotary knob 42 gently towards a clockwise direction; since thepositioning protrusion 14 is slightly resilient, thefirst slider 41 can be easily disengaged from the position limited by thepositioning protrusion 14; rotation of the rotary knob further drives thefirst slider 41 to move correspondingly within the guidingslot 16 under the guiding function of the guidingslot 16, and thefirst slider 41 in turns drives themovable element 5 to the left, and thus pushing out thetape guide 51 from thetape guide hole 11 until thetap guide 51 is completely pushed out; during the above described process, thefirst slider 41 is always positioned within thesecond slot section 532, and there is no corresponding change of position between thefirst slider 41 and thesecond slot section 532. When therotary knob 42 is further rotated to the clockwise direction, thefirst slider 41 slides from thesecond slot section 532 to thefirst slot section 531, while there is no corresponding change of position between themovable element 5 and the guidingslot 16. Finally, thefirst slider 41 is positioned at the retraction end of the guidingslot 16, whereas thepositioning protrusion 14 near to the retraction end prevents thefirst slider 41 from sliding downwardly driving therotary knob 42 to rotate anti-clockwise. When applying the tape during use, themovable element 5 is subject to a rightward horizontal pressure force F1; during application of the tape, thefirst slider 41 contacts and presses against a wall of thefirst slot section 531 of theposition limiting slot 53, wherein a contact surface between the first slider and the wall of the first slot section is an inclined surface or a curved surface at the round end of the closed end, therefore the contact surface is influenced by the inclination of the inclined straight slot (i.e. the first slot section 531), accordingly, thefirst slider 41 is subject to resilient force F2. When the contact surface is an inclined surface, F2 is perpendicular to the inclined surface; when the contact surface is a curved surface, F2 is oriented towards a center of circle of the curved surface at the round end. Therefore, along the clockwise direction along which therotary knob 42 rotates, there is a circumferential force F3, and this F3 is a component force of F2 along a vertical direction. F3 can facilitate rotation of therotary knob 42 along the clockwise direction, however, as a wall of the retraction end of the guidingslot 16 prevents therotary knob 42 to further rotate clockwise, F3 here is considered is a locking force. In view of the above, during application of the tape by the present invention, themovable element 5 can self-lock, thereby achieving self-locking of thetape guide 51. After application of the tape is finished, rotate therotary knob 42 towards an anti-clockwise direction such that thefirst slider 41 first slides in theposition limiting slot 53 from thefirst slot section 531 to thesecond slot section 532, and is limited within thesecond slot section 532; under the guiding function of the guidingslot 531, thefirst slider 41 will further slide in the guidingslot 16 from the retraction end to the extension end, and will eventually stop sliding under the limitation of a wall of the extension end, thereby retracting thetape guide 51 into thehousing 1 through thetape guide hole 11 and thus resuming the initial condition. - Compared with the prior art, the present invention can be operated quickly and conveniently during extension and retraction of the tape guide. Also, when the
tape guide 51 is completed extended, thefirst slider 41 is limited at the stop end of theposition limiting slot 53; when applying the tape, theposition limiting slot 53 has a locking force that prevents retraction of thefirst slider 41 during the course of applying the tape. - As shown in
FIGs. 5-6 ,embodiment 2 has the following differences compared with embodiment 1: structures of theposition limiting slot 53 and structures of the operating portion. - As shown, the
position limiting slot 53 is a compound slot, which comprises in a top-down sequence afirst slot section 531, asecond slot section 532 and athird slot section 533. Thefirst slot section 531, thesecond slot section 532 and thethird slot section 533 are in communication with one another, and all of them have equal depths. Thefirst slot section 531 is a horizontal straight slot; thesecond slot section 532 is a second inclined straight slot inclined to left side; thethird slot section 533 is a vertical straight slot; a stop end of thefirst slot section 531 is a closed end which can achieve stopping and position limiting. - In the current embodiment, the operating portion is an adjustment rod; one end of the adjustment rod is connected to the fixed end of the
first slider 41; another end of the adjustment rod is rotatably connected to a supporting point on thefirst housing section 12. The supporting point is a center of circle of an arc defined by the curved slot (i.e. the guiding slot 16). - The highest point of the
first slot section 531 is a closed end for stopping and position limiting. Thefirst slider 41 has a cylindrical shape. The closed end of theposition limiting slot 53 is a round end preferably corresponding to the cylindrical shape of thefirst slider 41. - When applying the tape, the
first slider 41 is limited in the first slot section 531 (the horizontal straight slot) of theposition limiting slot 53, and the movable element is subject to a rightward horizontal pressure force F1; during application of the tape, thefirst slider 41 contacts and presses against a wall of thefirst slot section 531 of theposition limiting slot 53, wherein a contact surface between the first slider and the wall of the first slot section is a curved surface at the round end of the closed end, accordingly, thefirst slider 41 is subject to resilient force F2, which is oriented towards a center of circle of the curved surface at the round end. Therefore, along the clockwise direction along which theadjustment rod 43 rotates, there is a circumferential force F3, and this F3 is a component force of F2 along a vertical direction. F3 can facilitate rotation of theadjustment rod 43 along the clockwise direction, however, as a wall of the retraction end of the guidingslot 16 prevents therotary knob 42 to further rotate clockwise, F3 here is considered is a locking force. In the current embodiment, as thefirst slot section 531 is a horizontal straight slot, the resilience force of F2 is oriented more closely to a vertical direction than the resilience force F2 inembodiment 1. Therefore, the resilient force F2 has a greater component force F3 along the vertical direction, meaning a greater locking force. - In the current embodiment, the
positioning slot 53 is provided with an inclined straight slot by means of which self-locking can be achieved. The self-locking as achieved is more secured. - As shown in
FIGs. 7-8 ,embodiment 3 has the following differences compared with embodiment 1: structures of theposition limiting slot 53 and structures of the guidingslot 16. - In the current embodiment, the
position limiting slot 53 is a straight slot, in particular, a vertical straight slot; apositioning protrusion 14 is provided at a side wall of the vertical straight slot near to the stop end of the vertical straight slot. The stop end of the vertical slot extends from the bottom zone of themovable element 5 up to the upper zone of themovable element 5. The guiding slot is a curved slot; an arc defined by the curved slot has a central angle less than 90 degrees; also, the retraction end of the guidingslot 16 extends to the upper zone of themovable element 5; the initial end of the vertical straight slot is provided within the bottom zone of themovable element 5. - When applying the tape, the
first slider 41 is limited at the stop end of the vertical straight slot, such that a circumferential force F3 facilitating therotary knob 42 to rotate clockwise is created during application of the tape. In here, F3 is considered a locking force. - It should be note that, the central angle of an arc defined by the curved slot can also be equal to 90 degrees.
- As shown in
Figs. 9-10 ,embodiment 4 has the following differences compared to embodiment 1: structures of the guidingslot 16 and structures of the operating portion. - The guiding slot is a compound slot, comprising a first

A range of movement allowed in the horizontal straight slot corresponds to a range of movement between the completely extended position and completely retracted position of thetape guide 51. In the current embodiment, the operating portion is apush button 44. Thepush button 44 is connected with the fixed end of thefirst slider 41; a diameter of thepush button 44 is larger than a slot width of the guidingslot 16; two opposite side walls of thepush button 44 are supported at slot walls of the guidingslot 16.
