Description

Technical Field

[0001] The present invention relates to the technical field of fasteners, and 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, since the first interval in the non-expanded state of the suitcase is smaller than the second interval in the expanded state, 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 longitudinal 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 longitudinal direction of the handle is fixed and cannot be well applied to suitcases with the above expansion function.

[0004] In addition, after sewing a fastener on a suitcase, the actual sewing position of the fastener may deviate from the ideal position. For a fastener whose lock head position cannot be changed, there is a problem that the lock head cannot be properly inserted into a dial lock during subsequent use.

Means for Solving the Problem

[0005] To achieve the above object, the present invention provides a telescopic lock handle. The telescopic lock handle includes a handle body having a slider connection portion at one end, a lock head, and a position regulating buffer member. A slide groove extending along the length direction is formed in the handle body. The lock head is movably connected to the slide groove along the extending direction of the slide groove. An attachment opening communicating with the slide groove is formed at an end of the slide groove of the handle body. The lock head is connected to the slide groove through the attachment opening. The position regulating buffer member is fixed to the handle body and closes the attachment opening. Both the handle body and the lock head are metal members, and the position regulating buffer member is a plastic member or a rubber member.

Effect of the Invention

[0006] In the telescopic lock handle, the lock head is movably connected into the slide groove along the extending direction of the slide groove, so that 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 length direction of the telescopic lock handle is variable. In this way, on the one hand, when the fastener to which the telescopic lock handle is attached is used to open and close a suitcase with an expansion function, the distance between the lock head of the fastener and the slider body is variable, so that the lock head can be well connected to the dial lock of the suitcase in both the non-expanded state and the expanded state of the suitcase, improving the convenience in use. On the other hand, regardless of whether the suitcase has an expansion function, when the fastener to which the telescopic lock handle is attached is used to open and close the suitcase, the variable position of the lock head can sufficiently offset the deviation of the actual sewing position of the fastener, enabling the lock head to be well connected to the dial lock of the suitcase and improving the convenience in use.

[0007] Furthermore, by providing the mounting opening, the lock head can be easily connected to the slide groove. After the lock head is attached, a position-limiting buffer member is used to block the mounting opening to prevent the lock head from coming off the slide groove and ensure that the lock head maintains a slidable connection relationship with the slide groove. In subsequent use, when the lock head slides relative to the slide groove, the slide member in the slide groove abuts against the position-limiting buffer member. The position-limiting buffer member is a plastic member or a rubber member and has a certain elasticity, so it performs an excellent buffering function. Also, since both the handle body and the lock head are metal members, the structural strength and wear resistance of the handle body and the lock head themselves are effectively improved, that is, the overall structural strength and wear resistance of the telescopic lock handle are improved, making the telescopic lock handle excellent in durability.

[0008] In the telescopic lock handle according to the present application, the lock head may be directly connected to the slide groove or indirectly connected to the slide groove via another member. The following provides two preferred structures.

[0009] Structure 1: The lock head is indirectly connected to the slide groove via a slide link. Based on this, the telescopic lock handle further includes a slide link. The slide link is movably mounted in the slide groove along the extending direction of the slide groove. The lock head is integrally formed at one end of the slide link and is distributed outside the handle body. The other end of the slide link is mounted in the slide groove through a mounting opening. The slide link is a metal member. By installing the slide link, the lock head can be installed outside the slide groove, without the need to lengthen the handle body, and the position of the lock head can be within the desired range, that is, the length of the handle body can be made relatively short. Also, after the lock head is installed outside the slide groove, the connection between the lock head and the dial lock is performed outside the handle body, and the handle body does not interfere with the locking by the lock head, which is convenient for the locking operation by the lock head. At the same time, the slide link and the lock head have an integrally formed structure and are an integral metal structure, with high product structure strength, high wear resistance, and excellent durability.

[0010] In the above technical means, a preferred structure in which the slide link is attached into the slide groove through the attachment opening is as follows. Along the width direction of the handle body, the width of the slide groove is smaller than the width of the attachment opening, whereby the handle body has slide support portions on both sides in the width direction of the slide groove. The slide link includes a link main body portion, a connection column portion, and a position regulating wing plate portion. The lock head is integrally formed at one end of the link main body portion. The connection column portion and the position regulating wing plate portion are integrally formed in sequence at the other end of the link main body portion along the thickness direction of the handle body. The attachment opening allows the connection column portion and the position regulating wing plate portion to pass through. The connection column portion is movably accommodated in the slide groove. The link main body portion and the position regulating wing plate portion are engaged on both sides of the slide support portion along the thickness direction of the handle body. Thereby, the slide link is securely held in the slide groove.

[0011] As a preferred means of the above technical means, the connection column portion and the slide groove are a clearance fit, whereby not only can the slide link slide smoothly in the slide groove, but also the slide link can be prevented from shifting greatly 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 handle body. The link main body portion is slidably accommodated in the guide groove. By providing the guide groove, the movement of the slide link in the slide groove is further guided, and the slide link is further prevented from shifting greatly in the width direction of the slide groove.

[0013] Structure 2: The lock head is directly connected to the slide groove, whereby the lock head is mounted in the slide groove, that is, the lock head is built into the slide groove. This structure is simple. Although it is necessary to lengthen the handle body, the number of parts of the telescopic lock handle is reduced, and the cost is reduced.

[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 handle body, the width of the slide groove is smaller than the width of the mounting opening. Thereby, the handle body has slide support portions on both sides in the width direction of the slide groove. The lock head includes a lock head main body portion and a lock head connection portion connected in sequence. The mounting opening allows at least one of the lock head main body portion or the lock head connection portion to pass through. A connection engagement groove parallel to the slide groove is formed in the lock head connection portion, and the slide support portion is engaged in the connection engagement groove. Thereby, the lock head is securely held in the slide groove.

[0015] In the above technical means, the mounting opening is formed at one end close to the slider connection portion of the slide groove. Thereby, the handle body has a mounting opening formed only at one end of the slide groove, and the other end of the slide groove is blocked by the self-structure of the handle body. When the slide link abuts against the position regulating buffer member, or when the lock head abuts against the position regulating buffer member, there is a minimum distance between the lock head and the slider body.

[0016] In the telescopic lock handle according to the present application, the fixing method of the position regulating buffer member and the handle body is also various.

[0017] Method 1: The position regulating buffer member is fixed to the handle body by injection molding, making the fixing more reliable. Further, reinforcing connection holes are formed in the handle body, and the 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 part 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 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 handle body after molding. At this time, the position regulating buffer member includes a cover plate portion, side wall portions extending along the thickness direction of the handle body from both sides of the cover plate portion, and disengaging claws extending from the inside of the side wall portions. The cover plate portion covers the surface of the handle body, the side wall portions cover the side surfaces of the handle body, and the disengaging claws are engaged with the back surface of the handle body, whereby the position regulating buffer member is firmly fixed to the handle body.

[0019] In the telescopic lock handle according to the present application, since the position regulating buffer member is a plastic member or a rubber member, it is easy to print a logo on the surface of the position regulating buffer member. By forming a logo on the surface of the position regulating buffer member, the functions of the telescopic lock handle are enriched.

[0020] The present application further provides a slider including a slider body and the above telescopic lock handle, and a slider connection portion of the handle body is connected to the slider body.

[0021] As described above, the telescopic lock handle and the slider according to the present invention have the following beneficial effects. In the telescopic lock handle according to the present application, the lock head is movably connected in the slide groove along the extending direction of the slide groove, whereby 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 length direction of the telescopic lock handle is variable. In this way, on the one hand, when the fastener to which the telescopic lock handle is attached is used to open and close a suitcase having an expansion function, the distance between the lock head of the fastener and the slider body is variable, whereby the lock head can be well connected to the dial lock of the suitcase in both the non-expanded state and the expanded state of the suitcase, and the convenience in use is improved. On the other hand, regardless of whether the suitcase has an expansion function or not, when the fastener to which the telescopic lock handle is attached is used to open and close the suitcase, the position of the lock head is variable, so that the deviation of the actual sewing position of the fastener can be sufficiently offset, the lock head can be well connected to the dial lock of the suitcase, and the convenience in use is improved.

[0022] Furthermore, by providing the mounting opening, the lock head can be easily connected to the slide groove. After the lock head is attached, the mounting opening is closed using the position regulating buffer member to prevent the lock head from coming off the slide groove and surely maintain the slidable connection relationship of the lock head with respect to the slide groove. In subsequent use, when the lock head slides with respect to the slide groove, the slide member in the slide groove abuts against the position regulating buffer member. The position regulating buffer member is a plastic member or a rubber member and has a certain elasticity, so it performs an excellent buffering function. Also, since both the handle body and the lock head are metal members, the structural strength and wear resistance of the handle body and the lock head themselves are effectively improved, that is, the overall structural strength and wear resistance of the telescopic lock handle are improved, whereby the telescopic lock handle is excellent in durability.

Embodiments for Carrying Out the Invention

[0024] Hereinafter, embodiments of the present invention will be described with reference to specific specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0025] It should be noted that the structures, proportions, sizes, etc. depicted in the drawings of this specification are all merely for those skilled in the art to understand and read in combination with the content disclosed in the specification, and are not intended to limit the limiting conditions under which the present invention can be implemented.

Also, terms such as "upper", "lower", "left", "right", "middle", and "one" cited in this specification are merely for convenience of explanation and do not limit the scope in which the present invention can be implemented. Unless there is a substantial change in the technical content, any change or adjustment in the relative relationship is also considered to be within the scope in which the present invention can be implemented.

[0026] It should be noted that when an element is shown as being "fixed to" or "installed on" another element, it may be directly fixed or installed on the other element, or an intermediate element may also be present at the same time. When an element is shown as being "connected to" another element, it may be directly connected to the other element, or indirectly connected to the other element via an intermediate element.

[0027] In addition, the descriptions regarding "first", "second", etc. in this application are for the purpose of explanation only, and should not be understood as indicating or implying their relative importance, or implicitly indicating the number of the specified technical features. Thus, the features limited as "first", "second" may explicitly or implicitly include at least one such feature. Also, the technical means of each embodiment cannot be combined unless those skilled in the art can implement it. If the combination of technical means is contradictory or cannot be implemented, it should be considered that such a combination of technical means does not exist and is not within the protection scope of this application.

[0028] This application relates to the technical field of fasteners and to a slider for a fastener. As shown in FIG. 16, the slider includes a slider body 60 and a telescopic locking handle with one end attached to the surface of the slider body 60. For the convenience of description, in the following embodiments, for each direction, the length direction of the telescopic locking handle is defined as the front-back direction, the width direction of the telescopic locking handle is defined as the left-right direction, and the thickness direction of the telescopic locking handle is defined as the up-down direction. Based on this, in the figures shown in FIGS. 3 and 9, the upper and lower sides of the paper surface are respectively the front direction and the back direction, the left and right sides of the paper surface are respectively the left direction and the right direction, and the front and back surfaces of the paper surface are respectively the up direction and the down direction. Also, the length direction, width direction, and thickness direction of the slider respectively coincide with the length direction, width direction, and thickness direction of the telescopic locking handle.

[0029] As shown in FIG. 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 handle connection portion 64 fixed to the upper surface of the upper wing plate 61, and the handle connection portion 64 is connected to the telescopic locking handle.

[0030] As shown in FIGS. 1 to 3 or FIGS. 7 to 9, the telescopic lock handle according to the present application includes a handle body 20, a lock head 30, and a position regulating and buffering member 40. A slider connection portion 10 is installed at the front end of the handle body 20. The slider connection portion 10 has an annular structure, and a mounting connection hole 11 is formed in the center. A slide groove 21 extending forward and backward along the length direction is formed in the handle body 20. The lock head 30 is connected to be movable back and forth in the slide groove 21 along the extending direction of the slide groove 21. The lock head 30 is connected to the dial lock of the suitcase and serves as a lock. At least one end of the two ends in the length direction of the slide groove 21 of the handle body 20 is formed with a mounting opening 22. 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 installed, the position regulating and buffering member 40 is fixed to the handle body 20 and closes the mounting opening 22. Both the handle body 20 and the lock head 30 are metal members, and the position regulating and buffering member 40 is a plastic member or a rubber member. The position regulating and buffering member 40 may be manufactured from materials such as hard plastic, soft plastic, rubber, etc. Accordingly, the position regulating and buffering member 40 may be a hard plastic member, a soft plastic member, or a rubber member.

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

[0032] In the above telescopic lock handle, 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 and rear positions of the lock head 30 in the extending direction of the slide groove 21 are variable, that is, the front and rear positions of the lock head 30 in the length direction of the telescopic lock handle are variable. Therefore, the lock head 30 has a telescopic structure in the front and rear directions. In this way, when the fastener to which the telescopic lock handle is attached is used to open and close a suitcase having 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 angle in Fig. 3 or Fig. 9 as an example, when the suitcase does not require an expansion function, the lock head 30 is moved forward in a direction approaching the slider body 60 to shorten the distance between the lock head 30 and the slider body 60. This is applied to the connection between the lock head 30 and the dial lock of the suitcase when the suitcase is in a non-expanded state. When the suitcase requires an expansion function, the lock head 30 is moved backward in a direction away from the slider body 60 to increase the distance between the lock head 30 and the slider body 60. This is applied to the connection between the lock head 30 and the dial lock of the suitcase when the suitcase is in an expanded state. Therefore, in the present application, by moving the lock head 30 back and forth with respect to the handle body 20, the lock head 30 can be successfully connected to the dial lock of the suitcase in both the non-expanded state and the expanded state of the suitcase, improving the convenience in use and satisfying the requirement that the position of the lock head 30 in the fastener of the suitcase having an expansion function is variable, or satisfying the requirement that the distance between the lock head 30 and the slider body 60 in the fastener of the suitcase having an expansion function is variable.Furthermore, regardless of whether the suitcase has an extended function, when the fastener to which the telescopic lock handle is attached is used to open and close the suitcase, the front and rear positions of the lock head 30 are variable, so that the deviation of the actual sewing position of the fastener can be sufficiently offset, a larger deviation of the actual sewing position of the fastener can be tolerated, and it is ensured that the lock head 30 can be successfully connected to the dial lock of the suitcase, thereby improving the convenience in use and the safety during use.

[0033] Furthermore, in the above telescopic lock handle, by forming the mounting opening 22 in the handle body 20, the lock head 30 can be easily connected to the slide groove 21. After the lock head 30 is installed, by installing the position regulating buffer member 40 to close the mounting opening 22, it is avoided that the lock head 30 comes off from 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 with respect to the slide groove 21, the slide member in the slide groove 21 abuts against the position regulating buffer member 40 when it slides to the mounting opening 22. The position regulating buffer member 40 is a plastic member or a rubber member, is a soft member, has a certain elasticity, and plays an excellent buffering role. Since both the handle body 20 and the lock head 30 are metal members, both the handle body 20 and the lock head 30 have excellent own structural strength and wear resistance, so that the overall structural strength and wear resistance of the telescopic lock handle are improved, and the telescopic lock handle is excellent in durability.

[0034] Furthermore, in the telescopic locking handle, the locking head 30 may be directly connected to the slide groove 21, or the locking 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 on the handle body 20, or may be fixed to the handle body 20 after injection molding. Based on the different connection structures between the locking head 30 and the slide groove 21 and the different fixing structures between the position regulating buffer member 40 and the handle body 20, the telescopic locking handle has a plurality of embodiments. Hereinafter, three preferred embodiments of the telescopic locking handle are provided.

[0035] The First Embodiment of the Telescopic Locking Handle As shown in FIGS. 1 to 3, in the first embodiment of the telescopic locking handle, the locking head 30 is indirectly connected to the slide groove 21 via the slide link 50. Thus, the first embodiment of the telescopic locking handle further includes a slide link 50 in addition to the handle body 20, the locking head 30, and the 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 locking head 30 is integrally formed at the rear end of the slide link 50. The locking head 30 is distributed outside the handle body 20, that is, the locking head 30 is an external structure with respect to the handle body 20 and the slide groove 21. The front end of the slide link 50 is mounted in the slide groove 21 through the mounting opening 22. The slide link 50 is a metal member.

[0036] In the first embodiment of the telescopic lock handle, by providing a slide link 50 directly mounted in the slide groove 21 and a structure in which the lock head 30 is integrally formed at the rear end of the slide link 50, it is realized that the lock head 30 slides back and forth with respect to the slide groove 21, enabling the lock head 30 to extend rearward and contract forward with respect to the handle body 20, and the lock head 30 can be installed outside the handle body 20 and the slide groove 21. When the lock head 30 adopts an external structure, on the one hand, by using a short handle body 20 and a slide link 50, it is possible to realize that the position of the lock head 30 within the desired front-rear range is variable, and since there is no need to lengthen the handle body 20, the length of the handle body 20 is relatively short. On the other hand, the connection between the lock head 30 and the dial lock is carried out outside the handle body 20, and the handle body 20 does not interfere with the locking by the lock head 30, which is convenient for the locking operation by the lock head 30. At the same time, the slide link 50 and the lock head 30 have an integrally formed structure, are an integral metal structure, have high product structure strength, high wear resistance, and excellent durability.

[0037] Furthermore, the mounting opening 22 may be formed at the front end and the rear end of the slide groove 21, or may be formed only at the front end or the rear end of the slide groove 21. In the first embodiment of the telescopic lock handle, as shown in FIG. 6, the mounting opening 22 is formed only at the front end of the slider connection portion 10 of the slide groove 21 of the handle body 20 close to the slider connection portion 10, and the closing end portion 26 is installed at the rear end of the slide groove 21 of the handle body 20. The front end and the rear end of the slide groove 21 are closed by the position regulating buffer member 40 and the closing end portion 26, respectively. In the process that the slide link 50 slides back and forth in the slide groove 21 to expand and contract the lock head 30 with respect to the handle body 20, when the slide link 50 slides forward to the front end of the slide groove 21 and abuts against the position regulating buffer member 40, as shown in FIG. 1, the position regulating buffer member 40 not only plays a buffering role but also can limit the further forward movement of the slide link 50. At this time, there is a minimum distance 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 abuts against the closing end portion 26, as shown in FIG. 4, the closing end portion 26 restricts the further backward movement of the slide link 50. At this time, there is a maximum distance between the lock head 30 and the slider body 60.

[0038] Furthermore, a preferred structure in which the slide link 50 is attached into the slide groove 21 through the attachment opening 22 is as follows. As shown in FIG. 6, along the left - right direction, the width of the slide groove 21 is smaller than the width of the attachment opening 22. Thereby, the 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 FIG. 5, the slide link 50 includes a link main body portion 51, a connection post portion 52, and a position - regulating wing plate portion 53. The link main body portion 51 extends in the front - rear direction, the lock head 30 is integrally formed at the rear end of the link main body portion 51, the connection post portion 52 is integrally formed at the front end of the link main body portion 51, extends vertically along the thickness direction of the handle body 20, and the position - regulating wing plate portion 53 is integrally formed at the lower end of the connection post portion 52 along the thickness direction of the handle body 20. The attachment opening 22 allows the connection post portion 52 and the position - regulating wing plate portion 53 to pass through. When attaching the slide link 50, first, the position - regulating wing plate portion 53 and the connection post portion 52 at the front end of the slide link 50 are sequentially inserted into the attachment opening 22. Next, the slide link 50 is moved rearward so that the connection post portion 52 is received in the slide groove 21. Finally, the position - regulating buffer member 40 is attached to the attachment opening 22, thereby completing the attachment of the slide link 50 having the lock head 30 at the rear end. When the attachment is completed, the connection post portion 52 is received in the slide groove 21 so as to be movable back and forth, and the link main body portion 51 and the position - regulating wing plate portion 53 are respectively engaged with the upper side and the lower side of the slide support portion 23 along the thickness direction of the handle body 20, thereby securely holding the slide link 50 in the slide groove 21.

[0039] Preferably, the connection post portion 52 and the slide groove 21 are clearance - fitted, whereby not only can the slide link 50 slide smoothly in the slide groove 21, but also the slide link 50 can be prevented from shifting greatly in the width direction of the slide groove 21.

[0040] Furthermore, as shown in FIGS. 1 and 6, the link body portion 51 is disposed on the upper surface, i.e., the surface, of the handle body 20. A guide groove 24 parallel to the slide groove 21 is formed on the upper surface of the handle body 20. The rear end of the guide groove 24 penetrates the handle body 20 rearward, and the link body portion 51 is slidably received in the guide groove 24 in the front-rear direction. The guide groove 24 is installed to better guide the forward and backward movement of the slide link 50 in the slide groove 21, and it is also possible to prevent the slide link 50 from greatly deviating in the width direction of the slide groove 21.

[0041] Furthermore, in the first embodiment of the telescopic locking handle, the position regulating and buffering member 40 is fixed to the handle body 20 by injection molding, making the fixation more reliable. Also, as shown in FIG. 3, the left edge portion of the position regulating and buffering member 40 does not protrude leftward from the left edge portion of the handle body 20, and the right edge portion of the position regulating and buffering member 40 does not protrude rightward from the right edge portion of the handle body 20. Preferably, as shown in FIG. 6, a reinforcing connection hole 25 penetrating vertically is formed at the front end of the handle body 20. The reinforcing connection hole 25 is distributed between the mounting connection hole 11 and the mounting opening 22, i.e., it is distributed on the front side opposite to the slide groove 21 of the mounting opening 22. After the position regulating and buffering member 40 is injection molded, a part of the position regulating and buffering member 40 is securely fitted into the reinforcing connection hole 25, thereby improving the reliability of the fixed connection between the position regulating and buffering member 40 and the 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 telescopic locking handle, the handle body 20 is an integral member, and the slide link 50 formed with the lock head 30, the connection post portion 52, and the position regulating wing plate portion 53 is also an integral member. In particular, both the handle body 20 and the slide link 50 are zinc alloy castings and are both manufactured by zinc alloy casting.

[0042] Second Embodiment of the Telescopic Locking Handle As shown in FIGS. 7 to 9, in the second embodiment of the telescopic lock handle, the lock head 30 is directly connected to the slide groove 21, so that the lock head 30 is mounted in the slide groove 21, and the lock head 30 has a built-in structure with respect to the handle body 20 and the slide groove 21. Although this structure is simple and it is necessary to lengthen the handle body 20, the number of parts of the telescopic lock handle is reduced and the cost is reduced. In particular, the built-in structure of the lock head 30 can better prevent undesirable phenomena such as detachment, deformation, and damage caused by the lock head 30 receiving force from the side.

[0043] As shown in FIGS. 8 and 10, in the second embodiment of the telescopic lock handle, the installation form of the mounting opening 22 is the same as that in the first embodiment of the telescopic lock handle, that is, the mounting opening 22 is formed only at the front end of the handle body 20 close to the slider connection portion 10 of the slide groove 21, and the closing end portion 26 is installed at the rear end of the slide groove 21 of the handle body 20, and the front end and the rear end of the slide groove 21 are closed by the position regulating buffer member 40 and the closing end portion 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 abuts against the position regulating buffer member 40, the position regulating buffer member 40 not only plays a buffering role but also can limit the lock head 30 from moving further forward. At this time, there is a minimum distance 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 abuts against the closing end portion 26, the closing end portion 26 restricts the lock head 30 from moving further backward. At this time, there is a maximum distance between the lock head 30 and the slider body 60.

[0044] Furthermore, a preferred structure in which the lock head 30 is attached into the slide groove 21 through the attachment opening 22 is as follows. As shown in FIGS. 10 and 11, along the left-right direction, the width of the slide groove 21 is smaller than the width of the attachment opening 22, whereby the handle main 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 FIGS. 14 and 15, the lock head 30 includes a lock head main body portion 31 and a lock head connection portion 32 connected in sequence, and at least one of the lock head main body portion 31 or the lock head connection portion 32 can pass through the attachment opening 22. 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 the connection engagement grooves 33 are preferably arc grooves. When attaching the lock head 30, the lock head main body portion 31 of the lock head 30 is inserted downward into the attachment opening 22 until the connection engagement groove 33 of the lock head connection portion 32 and the slide support portion 23 are aligned front and back. Next, the lock head 30 is moved backward so that the lock head connection portion 32 is accommodated in the slide groove 21. Finally, a position regulating buffer member 40 is attached to the attachment opening 22, thereby completing the attachment of the lock head 30. When the attachment is completed, the lock head connection portion 32 is accommodated in the slide groove 21 so as to be movable back and forth, and the slide support portion 23 is engaged in the connection engagement grooves 33 on both the left and right sides of the lock head connection portion 32, thereby securely holding the lock head 30 in the slide groove 21.

[0045] Furthermore, in the second embodiment of the telescopic locking handle, the position regulating buffer member 40 is first injection-molded and then engaged with the handle body 20. As shown in FIGS. 12 and 13, the position regulating buffer member 40 after injection molding includes a cover plate portion 41, side wall portions 42 extending downward along the thickness direction of the handle body 20 from both the left and right sides of the cover plate portion 41, and a retaining claw 43 extending from the inside of the side wall portions 42. The retaining claw 43 is installed at the middle position of 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 handle body 20, the two side wall portions 42 respectively cover the left and right side surfaces of the handle body 20, and the retaining claw 43 is engaged with the lower surface (i.e., the back surface) of the handle body 20. Thereby, the position regulating buffer member 40 is securely fixed to the handle body 20 and closes the mounting opening 22. Preferably, as shown in FIGS. 10 and 11, positioning engagement grooves 27 are installed at the left and right edge portions of the handle body 20, and the side wall portions 42 of the position regulating buffer member 40 are engaged in the positioning engagement grooves 27, which is convenient for the installation of the position regulating buffer member 40. A claw receiving groove 28 communicating with the positioning engagement groove 27 is installed on the lower surface of the handle body 20, and the retaining claw 43 is received in the claw receiving groove 28, reducing the protrusion feeling of foreign objects on the lower surface of the telescopic locking handle and improving the comfort during use.

[0046] Furthermore, in the second embodiment of the telescopic locking handle, the handle body 20 is an integral member, and the lock head 30 is also an integral member. In particular, both the handle body 20 and the lock head 30 are zinc alloy castings and are both manufactured by zinc alloy casting. Furthermore, in combination with the built-in structure in which the lock head 30 is directly connected to the slide groove 21, the handle body 20 surrounds the lock head 30, and both are metal members, having very good visual integrity.

[0047] Furthermore, in the first embodiment of the telescopic locking handle and the second embodiment of the telescopic locking handle, the mounting opening 22 is installed at the front end close to the slider connection portion 10 of the slide groove 21, that is, the mounting opening 22 is installed on the non-drawing side of the locking head 30 in the length direction of the slide groove 21. The telescopic locking handle is mainly used for a suitcase having an expansion function. When the suitcase is expanded to increase the thickness, it is necessary to pull the locking head 30 backward along the extending direction of the slide groove 21. If the mounting opening 22 is installed on the drawing side (i.e., the rear side) of the locking head 30 in the length direction of the slide groove 21, the locking head 30 may be damaged under tension, and furthermore, the locking head 30 may come off from the mounting opening 22. Therefore, in the present application, by installing the mounting opening 22 at the front end close to the slider connection portion 10 of the slide groove 21, it is possible to effectively prevent the locking head 30 from coming off from the mounting opening 22.

[0048] The third embodiment of the telescopic locking handle and the fourth embodiment of the telescopic locking handle When the position regulating and buffering member 40 in the first embodiment of the telescopic locking handle is lengthened as a whole, the third embodiment of the telescopic locking handle shown in FIG. 17 is obtained. When the position regulating and buffering member 40 in the second embodiment of the telescopic locking handle is lengthened as a whole, the fourth embodiment of the telescopic locking handle shown in FIG. 18 is obtained. Therefore, in the third embodiment of the telescopic locking handle and the fourth embodiment of the telescopic locking handle, the length of the slide groove 21 becomes shorter, and the length of the mounting opening 22 of the handle body 20 increases, whereby the overall length of the position regulating and buffering member 40 increases. In this way, the position regulating and buffering member 40 has a relatively large area. In particular, the position regulating and buffering member 40 has a relatively large surface area. The position regulating and buffering member 40 is a plastic member or a rubber member. When the surface area of the position regulating and buffering member 40 increases, a logo can be conveniently and easily printed on the surface of the position regulating and buffering member 40, whereby a logo or a drawing is formed on the surface of the position regulating and buffering member 40, which can be more eye-catching and can enrich the function of the telescopic locking handle.

[0049] Further, in the fourth embodiment of the telescopic lock handle, when the entire position regulating buffer member 40 becomes longer, the positioning engagement groove 27 also becomes longer accordingly, whereby the area of the engagement portion between the position regulating buffer member 40 and the positioning engagement groove 27 increases, the fixing reliability of the position regulating buffer member 40 is improved, and the detachment of the position regulating buffer member 40 is effectively avoided.

[0050] The Fifth Embodiment of the Telescopic Lock Handle and the Sixth Embodiment of the Telescopic Lock Handle When the position regulating buffer member 40 in the first embodiment of the telescopic lock handle is partially lengthened, the fifth embodiment of the telescopic lock handle shown in FIG. 19 is obtained. When the position regulating buffer member 40 in the second embodiment of the telescopic lock handle is partially lengthened, the sixth embodiment of the telescopic lock handle shown in FIG. 20 is obtained. Therefore, in the fifth embodiment of the telescopic lock handle and the sixth embodiment of the telescopic lock handle, as shown in FIGS. 19 and 20, on the rear side of the position regulating buffer member 40, a buffer member extending portion 44 extending rearward is integrally installed, and the buffer member extending portion 44 covers the front stage portion of the slide groove 21. By installing the buffer member extending portion 44, the movement range of the lock head 30 can be restricted, the movement range of the lock head 30 can be reduced, and it is applied when it is not necessary to move the lock head 30 very much.

[0051] As described above, the present invention effectively overcomes various drawbacks in the prior art and has high industrial utility value.

[0052] The above embodiments merely exemplarily explain the principle and effects of the present invention and do not limit the present invention. A person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by a person skilled in the art without departing from the spirit and technical idea disclosed in the present invention should still be covered by the claims of the present invention.
