Description

Technical Field

[0001] The present invention relates to the technical field of fasteners, and more particularly to a telescopic locking handle and a slider including the telescopic locking handle.

Background Art

[0002] Currently, most suitcases are provided with a dial lock and a fastener for opening and closing the suitcase. A lock head is fixedly installed on the handle of the fastener, and the connection between the lock head and the dial lock locks the suitcase, improving the safety when using the suitcase.

Summary of the Invention

Problems to be Solved by the Invention

[0003] Furthermore, some suitcases have additional expansion functions. When there is little luggage in the suitcase, there is no need to use its expansion function. At this time, the vertical distance between the slider body of the fastener for opening and closing the suitcase and the dial lock is a first interval. When there is a lot of luggage in the suitcase, it is necessary to use its expansion function to expand the storage space inside the suitcase. At this time, the vertical distance between the slider body of the fastener for opening and closing the suitcase and the dial lock is a second interval. Usually, the first interval in the non-expanded state of the suitcase is smaller than the second interval in the expanded state. Therefore, in order to simultaneously satisfy the connection between the lock head and the dial lock at the first interval and the second interval, the position of the lock head in the length direction of the handle needs to be variable. However, in conventional fasteners, the lock head is usually integrally formed at the outer end of the handle, so the position of the lock head in the length direction of the handle is fixed and cannot be well applied to suitcases with the above expansion function.

[0004] Furthermore, after sewing the zipper onto the suitcase, the actual sewing position of the zipper may deviate from the ideal position. In the case of zippers where the position of the lock head cannot be changed, there is a problem in subsequent use where the lock head cannot be properly inserted into the dial lock. [Means for solving the problem]

[0005] To achieve the above objective, the present invention provides a retractable locking pull handle, the retractable locking pull handle comprising a pull handle body having a slider connection portion at one end, a lock head, and a position-regulating buffer member, wherein the pull handle body has a slide groove extending along its longitudinal direction, the lock head is movably connected to the slide groove along the extending direction of the slide groove, a mounting opening communicating with the slide groove is formed at the end of the slide groove of the pull handle body, the lock head is connected to the slide groove through the mounting opening, the position-regulating buffer member is fixed to the pull handle body and closes the mounting opening, the pull handle body and lock head are both metal members, and the position-regulating buffer member is a plastic member or a rubber member. [Effects of the Invention]

[0006] In this retractable lock pull, the lock head is movably connected within the slide groove along the extending direction of the slide groove, thereby the position of the lock head in the extending direction of the slide groove is variable, i.e., the position of the lock head in the longitudinal direction of the retractable lock pull is variable. Thus, on the one hand, when a zipper to which this retractable lock pull is attached is used to open and close a suitcase with an expansion function, the distance of the lock head of the zipper from the slider body is variable, thereby allowing the lock head to connect well with the dial lock of the suitcase in both the non-expanded and expanded states of the suitcase, improving usability. On the other hand, when a zipper to which this retractable lock pull is attached is used to open and close a suitcase, regardless of whether the suitcase has an expansion function or not, the variable position of the lock head can sufficiently compensate for deviations in the actual stitching position of the zipper, allowing the lock head to connect well with the dial lock of the suitcase, improving usability.

[0007] Furthermore, by providing a mounting opening, the lock head can be easily connected to the slide groove. After the lock head is installed, a position-retaining buffer member is used to close the mounting opening, preventing the lock head from coming out of the slide groove and ensuring a secure connection that allows the lock head to slide relative to the slide groove. During subsequent use, when the lock head slides relative to the slide groove, the slide member within the slide groove comes into contact with the position-retaining buffer member. The position-retaining buffer member is made of plastic or rubber and has a certain elasticity, thus providing excellent cushioning. In addition, since both the pull handle body and the lock head are made of metal, the structural strength and wear resistance of the pull handle body and lock head themselves are effectively improved, that is, the overall structural strength and wear resistance of the retractable lock pull handle are improved, and as a result, the retractable lock pull handle is highly durable.

[0008] In the retractable locking pull handle according to the present invention, the locking head may be directly connected to the slide groove or indirectly connected to the slide groove via another member, and the following two preferred structures are provided.

[0009] Structure 1: The lock head is indirectly connected to the slide groove via a slide link. Based on this, the retractable lock pull handle further includes a slide link, which is mounted to be movable within the slide groove along the extending direction of the slide groove. The lock head is integrally molded to one end of the slide link and distributed outside the pull handle body. The other end of the slide link is mounted within the slide groove through a mounting opening. The slide link is a metal component. By installing the slide link, the lock head can be positioned outside the slide groove, eliminating the need to lengthen the pull handle body and allowing the position of the lock head to be within a desired range, i.e., the length of the pull handle body can be made relatively short. Furthermore, after positioning the lock head outside the slide groove, the connection between the lock head and the dial lock is made outside the pull handle body, so the pull handle body does not interfere with locking by the lock head, making locking operation by the lock head convenient. At the same time, the slide link and lock head are integrally molded structures, being one-piece metal structures, resulting in high product structural strength, high wear resistance, and excellent durability.

[0010] In the above technical means, a preferred structure in which the slide link is mounted in the slide groove through the mounting opening is as follows: Along the width direction of the pull handle body, the width of the slide groove is smaller than the width of the mounting opening, so that the pull handle body has slide support portions on both sides in the width direction of the slide groove, the slide link includes a link body portion, a connecting column portion, and a position-regulating wing plate portion, the lock head is integrally molded at one end of the link body portion, the connecting column portion and the position-regulating wing plate portion are integrally molded sequentially at the other end of the link body portion along the thickness direction of the pull handle body, the mounting opening is passable to the connecting column portion and the position-regulating wing plate portion, the connecting column portion is movably housed in the slide groove, and the link body portion and the position-regulating wing plate portion engage with both sides of the slide support portion along the thickness direction of the pull handle body. As a result, the slide link is securely held in the slide groove.

[0011] A preferred means of the above technical means is that the connecting column and the slide groove are fitted together, which not only allows the slide link to slide smoothly in the slide groove, but also prevents the slide link from shifting significantly in the width direction of the slide groove.

[0012] As a preferred means of the above technical means, a guide groove parallel to the slide groove is formed on the surface of the pull handle body, and the link body is slidably housed in the guide groove. By installing a guide groove, the movement of the slide link within the slide groove is further guided, and the slide link is less likely to shift significantly in the width direction of the slide groove.

[0013] Structure 2: The lock head is directly connected to the slide groove, thereby mounting the lock head within the slide groove; that is, the lock head is built into the slide groove. This structure is simple and requires a longer pull handle body, but it reduces the number of parts in the retractable lock handle and lowers costs.

[0014] In the above technical means, a preferred structure in which the lock head is mounted in the slide groove through the mounting opening is as follows: Along the width direction of the pull handle body, the width of the slide groove is smaller than the width of the mounting opening, so that the pull handle body has slide support portions on both sides in the width direction of the slide groove, the lock head includes a lock head body portion and a lock head connection portion connected in order, the mounting opening is passable to at least one of the lock head body portion or the lock head connection portion, the lock head connection portion has a connection engagement groove parallel to the slide groove, and the slide support portion is engaged in the connection engagement groove. As a result, the lock head is securely held in the slide groove.

[0015] In the above technical means, the mounting opening is formed at one end of the slide groove adjacent to the slider connection portion, so that the pull handle body has a mounting opening formed only at one end of the slide groove, and the other end of the slide groove is closed by the structure of the pull handle body itself. When the slide link comes into contact with the position-regulating buffer member, or when the lock head comes into contact with the position-regulating buffer member, a minimum distance exists between the lock head and the slider body.

[0016] In the retractable locking pull handle according to the present invention, there are various methods for fixing the position-regulating buffer member to the pull handle body.

[0017] Method 1: The position-regulating buffer member is fixed to the pull handle body by injection molding, making the fixation more secure. In addition, reinforcing connection holes are formed in the pull handle body, and these reinforcing connection holes are distributed on the side opposite to the slide groove of the mounting opening. After the position-regulating buffer member is injection-molded, a portion of the position-regulating buffer member is fitted into the reinforcing connection holes, further improving the reliability of the fixed connection between the position-regulating buffer member and the pull handle body, and further improving the reliability of holding the slide link in the slide groove.

[0018] Method 2: The position-regulating buffer member is engaged with the pull handle body after molding. In this case, the position-regulating buffer member includes a cover plate portion, side wall portions extending from both sides of the cover plate portion along the thickness direction of the pull handle body, and retaining claws extending from the inside of the side wall portions. The cover plate portion covers the surface of the pull handle body, the side wall portions cover the sides of the pull handle body, and the retaining claws engage with the back surface of the pull handle body, thereby securely fixing the position-regulating buffer member to the pull handle body.

[0019] In the retractable lock pull according to the present invention, since the position-regulating buffer member is made of plastic or rubber, it is easy to print a logo on the surface of the position-regulating buffer member, and by forming a logo on the surface of the position-regulating buffer member, the functionality of the retractable lock pull is enhanced.

[0020] The present invention further provides a slider including a slider body and the above-mentioned retractable locking handle, wherein the slider connection portion of the handle body is connected to the slider body.

[0021] As described above, the retractable locking handle and slider according to the present invention have the following beneficial effects. In the retractable lock pull according to the present invention, the lock head is movably connected within the slide groove along the extending direction of the slide groove, thereby the position of the lock head in the extending direction of the slide groove is variable, that is, the position of the lock head in the longitudinal direction of the retractable lock pull is variable. Thus, on the one hand, when the zipper to which the retractable lock pull is attached is used to open and close a suitcase with an expansion function, the distance of the lock head of the zipper from the slider body is variable, thereby the lock head can connect well with the dial lock of the suitcase in both the non-expanded and expanded states of the suitcase, improving usability. On the other hand, when the zipper to which the retractable lock pull is attached is used to open and close a suitcase, regardless of whether the suitcase has an expansion function or not, the variable position of the lock head can sufficiently compensate for deviations in the actual sewing position of the zipper, the lock head can connect well with the dial lock of the suitcase, and improving usability.

[0022] Furthermore, by providing a mounting opening, the lock head can be easily connected to the slide groove. After the lock head is installed, a position-retaining buffer member is used to close the mounting opening, preventing the lock head from coming out of the slide groove and ensuring a secure connection that allows the lock head to slide relative to the slide groove. During subsequent use, when the lock head slides relative to the slide groove, the slide member within the slide groove comes into contact with the position-retaining buffer member. The position-retaining buffer member is made of plastic or rubber and has a certain elasticity, thus providing excellent cushioning. In addition, since both the pull handle body and the lock head are made of metal, the structural strength and wear resistance of the pull handle body and lock head themselves are effectively improved, that is, the overall structural strength and wear resistance of the retractable lock pull handle are improved, and as a result, the retractable lock pull handle is highly durable.

[Modes for carrying out the invention]

When one element is described as being "connected" to another element, it may be directly connected to the other element, or it may be indirectly connected to the other element via an intermediate element.

[0027] Furthermore, the descriptions of "first," "second," etc., in this application are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of specified technical features. Thus, features limited as "first" or "second" may explicitly or implicitly include at least one such feature. Also, the technical means of each embodiment cannot be combined unless they can be realized by a person skilled in the art. If a combination of technical means is contradictory or unrealizable, such a combination of technical means should be considered nonexistent and not within the scope of protection of this application.

[0028] This application relates to the technical field of fasteners, and more particularly to a slider for a fastener. As shown in Figure 16, the slider includes a slider body 60 and a retractable lock pull tab with one end attached to the surface of the slider body 60. For convenience of explanation, in the following embodiments, the length direction of the retractable lock pull tab is defined as the front-to-back direction, the width direction of the retractable lock pull tab as the left-to-right direction, and the thickness direction of the retractable lock pull tab as the up-to-down direction. Accordingly, in the diagrams shown in Figures 3 and 9, the upper and lower sides of the paper are defined as the front and back directions, respectively, the left and right sides of the paper as the left and right directions, respectively, and the front and back surfaces of the paper as the up and down directions, respectively. Furthermore, the length, width, and thickness directions of the slider coincide with the length, width, and thickness directions of the retractable lock pull tab, respectively.

[0029] As shown in Figure 16, the slider body 60 includes an upper wing plate 61 and a lower wing plate 62 connected vertically along its thickness direction, an element passage 63 formed between the upper wing plate 61 and the lower wing plate 62, and a pull handle connection part 64 fixed to the upper surface of the upper wing plate 61. The pull handle connection part 64 is connected to a retractable locking pull handle.

[0030] As shown in Figures 1 to 3, or as shown in Figures 7 to 9, the retractable locking pull handle according to the present invention includes a pull handle body 20, a lock head 30, and a position-regulating buffer member 40. A slider connection part 10 is installed at the front end of the pull handle body 20, and the slider connection part 10 has an annular structure with a mounting connection hole 11 formed in the center. A slide groove 21 is formed in the pull handle body 20, extending front to back along its longitudinal direction, and the lock head 30 is connected to the slide groove 21 so as to be movable front to back along the extending direction of the slide groove 21, and the lock head 30 is connected to the dial lock of the suitcase and performs the function of locking. A mounting opening 22 is formed at at least one of the two ends of the slide groove 21 in the longitudinal direction of the pull handle body 20, and the mounting opening 22 communicates with the slide groove 21, and the lock head 30 is connected to the slide groove 21 through the mounting opening 22. After the lock head 30 is attached, the position-regulating buffer member 40 is fixed to the pull handle body 20 and closes the mounting opening 22. The pull handle body 20 and the lock head 30 are both metal components, while the position-regulating buffer member 40 is made of plastic or rubber. The position-regulating buffer member 40 may be made of materials such as hard plastic, soft plastic, or rubber, and accordingly, the position-regulating buffer member 40 may be made of hard plastic, soft plastic, or rubber.

[0031] When the retractable lock pull is connected to the slider body 60, the slider connection portion 10 at the front end of the pull pull body 20 is fitted into the pull pull connection portion 64 of the slider body 60 through its mounting connection hole 11, thereby connecting the pull pull body 20 to the slider body 60. By holding the retractable lock pull in one's hand, it becomes easy to pull the slider back and forth along the length of the zipper, thereby opening and closing the zipper.

[0032] In the above-described retractable lock pull, the lock head 30 is connected to the slide groove 21 so as to be movable back and forth along the extending direction of the slide groove 21. As a result, the front-to-back position of the lock head 30 in the extending direction of the slide groove 21 is variable, that is, the front-to-back position of the lock head 30 in the longitudinal direction of the retractable lock pull is variable, and therefore the lock head 30 has a retractable structure in the front-to-back direction. Thus, when the zipper to which the retractable lock pull is attached is used to open and close a suitcase that has an expansion function, the distance between the lock head 30 and the slider body 60 becomes variable as the lock head 30 moves back and forth. Taking the angles in Figure 3 or Figure 9 as an example, when the suitcase does not require an expansion function, the lock head 30 is moved forward in a direction that brings it closer to the slider body 60, shortening the distance between the lock head 30 and the slider body 60. This applies to the connection between the lock head 30 and the dial lock of the suitcase when the suitcase is in a non-expanded state. If the suitcase requires an expansion function, the lock head 30 is moved backward away from the slider body 60, increasing the distance between the lock head 30 and the slider body 60. This applies to the connection between the lock head 30 and the suitcase's dial lock when the suitcase is in the expanded state. Therefore, in this application, by moving the lock head 30 back and forth relative to the pull tab body 20, the lock head 30 can connect well with the suitcase's dial lock in both the unexpanded and expanded states of the suitcase, improving usability and satisfying the requirement that the position of the lock head 30 on the zipper of a suitcase with an expansion function is variable, or that the distance between the lock head 30 and the slider body 60 on the zipper of a suitcase with an expansion function is variable.Furthermore, regardless of whether the suitcase has an expansion function or not, when the zipper to which the retractable lock pull is attached is used to open and close the suitcase, the front-to-back position of the lock head 30 is variable, thereby sufficiently compensating for any deviation in the actual stitching position of the zipper, allowing for greater deviations in the actual stitching position of the zipper, ensuring that the lock head 30 can connect properly with the dial lock of the suitcase, thereby improving convenience and safety during use.

[0033] Furthermore, in the above-described retractable lock pull handle, by forming a mounting opening 22 in the pull handle body 20, the lock head 30 can be easily connected to the slide groove 21. After attaching the lock head 30, by installing the position-regulating buffer member 40 to close the mounting opening 22, the lock head 30 is prevented from coming out of the slide groove 21, and a slidable connection relationship between the lock head 30 and the slide groove 21 is reliably maintained. In subsequent use, when the lock head 30 slides back and forth in relation to the slide groove 21, the sliding member in the slide groove 21 comes into contact with the position-regulating buffer member 40 when it slides into the mounting opening 22. The position-regulating buffer member 40 is made of plastic or rubber, is a soft material with a certain elasticity, and plays an excellent cushioning role. Since both the pull handle body 20 and the lock head 30 are made of metal, both the pull handle body 20 and the lock head 30 have excellent structural strength and wear resistance, thereby improving the overall structural strength and wear resistance of the retractable lock pull handle, and making the retractable lock pull handle highly durable.

[0034] Furthermore, in the above-described retractable locking pull handle, the lock head 30 may be directly connected to the slide groove 21, or the lock head 30 may be indirectly connected to the slide groove 21 via other members. The position-regulating buffer member 40 may be directly injection-molded into the pull handle body 20, or it may be fixed to the pull handle body 20 after injection molding. Based on different connection structures between the lock head 30 and the slide groove 21, and different fixing structures between the position-regulating buffer member 40 and the pull handle body 20, the retractable locking pull handle has multiple embodiments. Below, three preferred embodiments of the retractable locking pull handle are provided.

[0035] First embodiment of a retractable locking pull handle As shown in Figures 1 to 3, in the first embodiment of the retractable locking pull handle, the lock head 30 is indirectly connected to the slide groove 21 via a slide link 50. Thus, the first embodiment of the retractable locking pull handle further includes a slide link 50 in addition to the pull handle body 20, lock head 30, and position-regulating buffer member 40. The slide link 50 is mounted in the slide groove 21 so as to be movable back and forth along the extending direction of the slide groove 21, the lock head 30 is integrally molded to the rear end of the slide link 50, the lock head 30 is distributed outside the pull handle body 20, that is, the lock head 30 is an external structure to the pull handle body 20 and the slide groove 21, the front end of the slide link 50 is mounted in the slide groove 21 through a mounting opening 22, and the slide link 50 is a metal member.

[0036] In the first embodiment of the retractable locking pull handle, by installing a slide link 50 directly mounted in the slide groove 21 and a lock head 30 integrally molded at the rear end of the slide link 50, the lock head 30 can slide back and forth relative to the slide groove 21, enabling the lock head 30 to extend rearward and retract forward relative to the pull handle body 20, and allowing the lock head 30 to be installed outside the pull handle body 20 and the slide groove 21. When the lock head 30 employs an external structure, on the one hand, by using a short pull handle body 20 and slide link 50, the position of the lock head 30 within a desired front-to-back range can be made variable, and since there is no need to lengthen the pull handle body 20, the length of the pull handle body 20 can be made relatively short. On the other hand, the connection between the lock head 30 and the dial lock is made outside the pull handle body 20, and the pull handle body 20 does not interfere with the locking by the lock head 30, making the locking operation by the lock head 30 convenient. At the same time, the slide link 50 and the lock head 30 are integrally molded structures, being one-piece metal structures, resulting in high product structural strength, high wear resistance, and excellent durability.

[0037] Furthermore, the mounting opening 22 may be formed at the front and rear ends of the slide groove 21, or it may be formed only at the front or rear end of the slide groove 21. In the first embodiment of the retractable lock pull handle, as shown in Figure 6, the mounting opening 22 is formed only at the front end of the slide groove 21 of the pull handle body 20 that is close to the slider connection portion 10, and a closing end 26 is installed at the rear end of the slide groove 21 of the pull handle body 20, and the front and rear ends of the slide groove 21 are closed by the position-restricting buffer member 40 and the closing end 26, respectively. In the process in which the slide link 50 slides back and forth in the slide groove 21 to extend and retract the lock head 30 relative to the pull handle body 20, when the slide link 50 slides forward to the front end of the slide groove 21 and comes into contact with the position-restricting buffer member 40, as shown in Figure 1, the position-restricting buffer member 40 not only plays a buffering role but can also restrict the slide link 50 from moving further forward, and at this time there is a minimum gap between the lock head 30 and the slider body 60. When the slide link 50 slides backward to the rear end of the slide groove 21 and comes into contact with the blocking end 26, as shown in Figure 4, the blocking end 26 restricts the slide link 50 from moving further backward, and at this time, there is a maximum gap between the lock head 30 and the slider body 60.

[0038] Furthermore, a preferred structure in which the slide link 50 is mounted in the slide groove 21 through the mounting opening 22 is as follows: As shown in Figure 6, the width of the slide groove 21 is smaller than the width of the mounting opening 22 along the left-right direction, so that the pull handle body 20 has slide support portions 23 on both the left and right sides in the width direction of the slide groove 21. As shown in Figure 5, the slide link 50 includes a link body portion 51, a connecting column portion 52, and a position regulating wing plate portion 53. The link body portion 51 extends in the front-rear direction, the lock head 30 is integrally molded at the rear end of the link body portion 51, the connecting column portion 52 is integrally molded at the front end of the link body portion 51 and extends vertically along the thickness direction of the pull handle body 20, and the position regulating wing plate portion 53 is integrally molded at the lower end of the connecting column portion 52 along the thickness direction of the pull handle body 20. The mounting opening 22 is passable for the connecting column portion 52 and the position regulating wing plate portion 53. When installing the slide link 50, first, the position-regulating wing plate portion 53 and the connecting column portion 52 at the front end of the slide link 50 are inserted sequentially into the mounting opening 22. Next, the slide link 50 is moved backward so that the connecting column portion 52 is housed in the slide groove 21. Finally, the position-regulating buffer member 40 is attached to the mounting opening 22, thereby completing the installation of the slide link 50 having a lock head 30 at its rear end. Once the installation is complete, the connecting column portion 52 is housed in the slide groove 21 so as to be movable back and forth, and the link body portion 51 and the position-regulating wing plate portion 53 are engaged with the upper and lower sides of the slide support portion 23, respectively, along the thickness direction of the pull handle body 20, thereby securely holding the slide link 50 in the slide groove 21.

[0039] Preferably, the connecting column 52 and the slide groove 21 are fitted together, which not only allows the slide link 50 to slide smoothly in the slide groove 21, but also prevents the slide link 50 from shifting significantly in the width direction of the slide groove 21.

[0040] Furthermore, as shown in Figures 1 and 6, the link body portion 51 is positioned on the upper surface, i.e., the surface, of the pull handle body 20. A guide groove 24 parallel to the slide groove 21 is formed on the upper surface of the pull handle body 20, and the rear end of the guide groove 24 penetrates the pull handle body 20 to the rear. The link body portion 51 is housed within the guide groove 24 so as to be slidable back and forth. The guide groove 24 is positioned to better guide the back and forth movement of the slide link 50 within the slide groove 21, and can also prevent the slide link 50 from shifting significantly in the width direction of the slide groove 21.

[0041] Furthermore, in the first embodiment of the retractable locking pull handle, the position-regulating buffer member 40 is fixed to the pull handle body 20 by injection molding, making the fixation more secure. Also, as shown in Figure 3, the left edge of the position-regulating buffer member 40 does not protrude to the left from the left edge of the pull handle body 20, and the right edge of the position-regulating buffer member 40 does not protrude to the right from the right edge of the pull handle body 20. Preferably, as shown in Figure 6, a reinforcing connection hole 25 that penetrates vertically is formed at the front end of the pull handle body 20, and the reinforcing connection hole 25 is distributed between the mounting connection hole 11 and the mounting opening 22, that is, distributed on the front side opposite the slide groove 21 of the mounting opening 22. After the position-regulating buffer member 40 is injection molded, a part of the position-regulating buffer member 40 is securely fitted into the reinforcing connection hole 25, thereby improving the reliability of the fixed connection between the position-regulating buffer member 40 and the pull handle body 20, and further improving the reliability of holding the slide link 50 in the slide groove 21. Furthermore, in the first embodiment of the retractable locking pull handle, the pull handle body 20 is a single-piece component, and the slide link 50, which has the lock head 30, connecting column portion 52, and position regulating wing plate portion 53 molded into it, is also a single-piece component. In particular, both the pull handle body 20 and the slide link 50 are made of zinc alloy castings and are manufactured by zinc alloy casting.

[0042] Second embodiment of a retractable locking pull handle As shown in Figures 7 to 9, in the second embodiment of the retractable locking pull handle, the lock head 30 is directly connected to the slide groove 21, so that the lock head 30 is mounted within the slide groove 21, and the lock head 30 has an internal structure relative to the pull handle body 20 and the slide groove 21. This structure is simple and requires the pull handle body 20 to be longer, but it reduces the number of parts in the retractable locking pull handle and reduces costs. In particular, the internal structure of the lock head 30 can better prevent undesirable phenomena such as detachment, deformation, and damage to the lock head 30 due to force from the side.

[0043] As shown in Figures 8 and 10, in the second embodiment of the retractable lock pull handle, the mounting opening 22 is installed in the same manner as in the first embodiment of the retractable lock pull handle. That is, the mounting opening 22 is formed only at the front end of the slide groove 21 of the pull handle body 20 that is close to the slider connection portion 10, and a closing end 26 is installed at the rear end of the slide groove 21 of the pull handle body 20. The front and rear ends of the slide groove 21 are closed by the position-restricting buffer member 40 and the closing end 26, respectively. In the process of the lock head 30 sliding back and forth in the slide groove 21, when the lock head 30 slides forward to the front end of the slide groove 21 and comes into contact with the position-restricting buffer member 40, the position-restricting buffer member 40 not only acts as a buffer but also restricts the lock head 30 from moving further forward. At this time, a minimum gap exists between the lock head 30 and the slider body 60. When the lock head 30 slides backward to the rear end of the slide groove 21 and comes into contact with the blocking end 26, the blocking end 26 restricts the lock head 30 from moving further backward, and at this time, there is a maximum gap between the lock head 30 and the slider body 60.

[0044] Furthermore, a preferred structure in which the lock head 30 is mounted in the slide groove 21 through the mounting opening 22 is as follows: As shown in Figures 10 and 11, the width of the slide groove 21 is smaller than the width of the mounting opening 22 along the left-right direction, so that the pull handle body 20 has slide support portions 23 on both the left and right sides in the width direction of the slide groove 21. As shown in Figures 14 and 15, the lock head 30 includes a lock head body portion 31 and a lock head connection portion 32 connected in order, the mounting opening 22 is passable to at least one of the lock head body portion 31 or the lock head connection portion 32, and connection engagement grooves 33 parallel to the slide groove 21 are formed on both the left and right sides of the lock head connection portion 32, and it is preferable that the connection engagement grooves 33 are arc grooves. When installing the lock head 30, the lock head body 31 of the lock head 30 is inserted downward into the mounting opening 22 until the connection engagement groove 33 of the lock head connection part 32 and the slide support part 23 are aligned front to back. Next, the lock head 30 is moved rearward so that the lock head connection part 32 is housed in the slide groove 21. Finally, the position regulating buffer member 40 is attached to the mounting opening 22, thereby completing the installation of the lock head 30. Once the installation is complete, the lock head connection part 32 is housed in the slide groove 21 so as to be movable front to back, and the slide support part 23 engages with the connection engagement grooves 33 on both the left and right sides of the lock head connection part 32, thereby securely holding the lock head 30 in the slide groove 21.

[0045] Furthermore, in a second embodiment of the retractable locking pull handle, the position-regulating buffer member 40 is first injection-molded and then engaged with the pull handle body 20. As shown in Figures 12 and 13, the injection-molded position-regulating buffer member 40 includes a cover plate portion 41, side wall portions 42 extending downward from both the left and right sides of the cover plate portion 41 along the thickness direction of the pull handle body 20, and a retaining claw 43 extending from the inside of the side wall portions 42, wherein the retaining claw 43 is positioned midway along the side wall portions 42 in the front-rear direction, the cover plate portion 41 covers the upper surface (i.e., the front surface) of the pull handle body 20, the two side wall portions 42 cover the left and right sides of the pull handle body 20 respectively, and the retaining claw 43 engages with the lower surface (i.e., the back surface) of the pull handle body 20, thereby securely fixing the position-regulating buffer member 40 to the pull handle body 20 and closing the mounting opening 22. Preferably, as shown in Figures 10 and 11, positioning engagement grooves 27 are provided on the left and right edges of the pull handle body 20, and the side walls 42 of the position-regulating buffer member 40 are engaged within the positioning engagement grooves 27, making it convenient to attach the position-regulating buffer member 40. A claw housing groove 28 communicating with the positioning engagement grooves 27 is provided on the lower surface of the pull handle body 20, and the retaining claw 43 is housed within the claw housing groove 28, reducing the feeling of foreign matter protruding from the lower surface of the retractable lock pull handle and improving comfort during use.

[0046] Furthermore, in a second embodiment of the retractable locking pull handle, the pull handle body 20 is a single integrated component, and the lock head 30 is also a single integrated component. In particular, both the pull handle body 20 and the lock head 30 are made of zinc alloy castings and are manufactured by zinc alloy casting. Moreover, by combining this with an internal structure in which the lock head 30 is directly connected to the slide groove 21, the pull handle body 20 surrounds the lock head 30, and both are metal components, resulting in a visually very good sense of unity.

[0047] Furthermore, in both the first and second embodiments of the retractable lock pull handle, the mounting opening 22 is located at the front end of the slide groove 21, close to the slider connection portion 10. That is, the mounting opening 22 is located on the non-pull-out side of the lock head 30 in the longitudinal direction of the slide groove 21. Retractable lock pull handles are mainly used in suitcases with expansion capabilities. When expanding a suitcase to increase its thickness, it is necessary to pull the lock head 30 backward along the extending direction of the slide groove 21. If the mounting opening 22 is located on the pull-out side (i.e., the rear side) of the lock head 30 in the longitudinal direction of the slide groove 21, the lock head 30 may be subjected to tension and damaged, and may even detach from the mounting opening 22. Therefore, in this application, by installing the mounting opening 22 at the front end of the slide groove 21, close to the slider connection portion 10, it is possible to effectively prevent the lock head 30 from detaching from the mounting opening 22.

[0048] Third embodiment of the retractable locking pull handle and fourth embodiment of the retractable locking pull handle By lengthening the position-regulating buffer member 40 in the first embodiment of the telescopic lock pull handle described above, a third embodiment of the telescopic lock pull handle shown in Figure 17 can be obtained. By lengthening the position-regulating buffer member 40 in the second embodiment of the telescopic lock pull handle described above, a fourth embodiment of the telescopic lock pull handle shown in Figure 18 can be obtained. Therefore, in the third and fourth embodiments of the telescopic lock pull handle, the length of the slide groove 21 is shortened, the length of the mounting opening 22 of the pull handle body 20 is increased, and as a result, the overall length of the position-regulating buffer member 40 is increased. Thus, the position-regulating buffer member 40 has a relatively large area, and in particular, the position-regulating buffer member 40 has a relatively large surface area. The position-regulating buffer member 40 is made of plastic or rubber, and as the surface area of ​​the position-regulating buffer member 40 increases, a logo can be conveniently and easily printed on the surface of the position-regulating buffer member 40. This allows for the formation of a logo or drawing on the surface of the position-regulating buffer member 40, making it more eye-catching and enriching the functionality of the telescopic lock pull handle.

[0049] Furthermore, in the fourth embodiment of the retractable locking pull handle, as the overall length of the position-regulating buffer member 40 increases, the positioning engagement groove 27 also increases accordingly. This increases the area of ​​the engagement portion between the position-regulating buffer member 40 and the positioning engagement groove 27, improving the fixing reliability of the position-regulating buffer member 40 and effectively preventing the position-regulating buffer member 40 from coming loose.

[0050] Fifth embodiment of the retractable locking pull handle and sixth embodiment of the retractable locking pull handle By partially lengthening the position-restricting buffer member 40 in the first embodiment of the telescopic lock pull described above, a fifth embodiment of the telescopic lock pull shown in Figure 19 can be obtained. By partially lengthening the position-restricting buffer member 40 in the second embodiment of the telescopic lock pull described above, a sixth embodiment of the telescopic lock pull shown in Figure 20 can be obtained. Therefore, in the fifth and sixth embodiments of the telescopic lock pull, as shown in Figures 19 and 20, a buffer member extension portion 44 extending to the rear is integrally installed on the rear side of the position-restricting buffer member 40, and the buffer member extension portion 44 covers the front portion of the slide groove 21. By installing the buffer member extension portion 44, the range of movement of the lock head 30 can be limited, making the range of movement of the lock head 30 smaller, which is applicable when there is no need to move the lock head 30 much.
