Obviously, the described embodiments are some embodiments of the present application, not all embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art belong to the scope of protection of the present application.

[0028] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0029] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.

[0030] Example 1:

[0031] like Figures 1-9 As shown, a bag handle mounting structure includes a handle body 1, a base 2, and a connecting seat 3. In a specific embodiment of this utility model, a sliding groove 4 is provided on the base 2, and the connecting seat 3 is partially slidably installed in the sliding groove 4. An installation and fixing component is provided between the base 2 and the connecting seat 3 to make the connecting seat 3 further close to the base 2 during the sliding process and to vertically press and fix the bag shell 100 between the two.

[0032] In existing technologies, bag handles consist of numerous separate parts, and each end of the handle requires at least two screws for locking and fixing. Similarly, the clamping and fixing of the bag shell is also achieved using two screws. However, in this embodiment, the locking and installation between the base 2 and the connecting seat 3 is replaced by a mounting and fixing component. After the connecting seat 3 is inserted downwards into the slide groove 4, as the connecting seat 3 slides laterally, the mounting and fixing component causes the connecting seat 3 to further adhere to the base 2 during the sliding process, and vertically clamps and fixes the bag shell 100 between them. This makes installation convenient and quick, and eliminates the need for screws or other fasteners to achieve vertical clamping and fixing. The entire structure is simplified, production costs are reduced, and installation efficiency is improved.

[0033] Example 2:

[0034] The difference from the embodiment 1 is that, in addition to comprising the structural features of the preceding embodiments, in the specific embodiments of the utility model, the installation fixing assembly comprises at least a first block 11 arranged on one side of the connecting seat 3 and at least a second block 12 arranged on one side of the inner groove wall of the base 2, the first block 11 is provided with a first inclined surface 13, the second block 12 is provided with a second inclined surface 14 matched with the first inclined surface 13, and the inclination direction of the first inclined surface 13 is arranged to gradually incline downward along the sliding direction of the connecting seat 3.

[0035] As shown in the specific use, Figures 7-8 After the connecting seat 3 is inserted into the sliding groove 4, the first inclined surface 13 on the connecting seat 3 cooperates with the second inclined surface 14 in the sliding groove 4, and as the connecting seat 3 continuously slides to the right, the second inclined surface 14 presses the first inclined surface 13 downward, that is, the second block 12 presses the first block 11 downward, so that the connecting seat 3 is further pressed downward, thereby making the connecting seat 3 further close to the base 2 and vertically compressing and fixing the luggage shell 100 between the two during the sliding process.

[0036] Embodiment 3:

[0037] The difference from the embodiment 2 is that, in addition to comprising the structural features of the preceding embodiments, in the specific embodiments of the utility model, as shown in Figure 7 and Figure 8 The four first blocks 11 are arranged on the connecting seat 3, and the four second blocks 12 are arranged in the sliding groove 4 of the base 2, which are arranged in front and back symmetry, so that in the installation and use, the middle part of the connecting seat 3 is opposite to the two second blocks 12, so that the left second block 12 is between the two first blocks 11 during the process of the connecting seat 3 being inserted into the sliding groove 4, and then the connecting seat 3 is conveniently slid to the right side, so that the two second blocks 12 act on the first block 11 respectively, and then the installation between the connecting seat 3 and the base 2 is stable and reliable.

[0038] Embodiment 4:

[0039] The difference from the embodiment 2 is that, in addition to comprising the structural features of the preceding embodiments, in the specific embodiments of the utility model, the connecting seat 3 and the sliding groove 4 are further matched with the sliding limiting assembly for transversely limiting and fixing the base 2 and the connecting seat 3 after being vertically pulled tight.

[0040] During the installation of the bag handle, although the connecting seat 3 is pressed vertically into the slide groove 4 after sliding laterally into place, the lateral sliding restriction on the base 2 and the connecting seat 3 is not high. This will affect the installation stability of the bag handle. Therefore, in this embodiment, a sliding limit component is also provided between the connecting seat 3 and the slide groove 4, such as... Figure 9 As shown, during the process of the connecting seat 3 sliding to the right along the slide groove 4, the sliding limit component locks and fixes the connecting seat 3 in the horizontal direction. This achieves both vertical fixation of the connecting seat 3 and horizontal locking. As for the front and rear directions, the slide groove 4 itself limits the movement. Therefore, the connecting seat 3 is fixed in three directions after it is slid into place. The fixation is stable and high, and the installation is convenient, quick and easy. The structure is simple, and the whole structure represents a significant improvement over the existing technology.

[0041] Example 5:

[0042] The difference from Embodiment 4 is that, in addition to including the structural features of the aforementioned embodiments, in this specific embodiment of the present invention, the sliding limiting component includes a first protrusion 15 at least disposed on the outer side wall of the connecting seat 3 and a second protrusion 16 at least disposed on the groove wall of the sliding groove 4. A plurality of triangular protrusions 17 are sequentially disposed on the opposite side walls of the first protrusion 15 and the second protrusion 16 along the sliding direction of the connecting seat 3, and a slot 18 is formed between adjacent triangular protrusions 17 for the triangular protrusions 17 to be inserted.

[0043] like Figure 7 and Figure 8 As shown, after the connecting seat 3 is inserted into the slide groove 4, as the connecting seat 3 slides laterally in the slide groove 4, the first inclined surface 13 on the connecting seat 3 cooperates with the second inclined surface 14 located in the slide groove 4. As the connecting seat 3 continues to slide to the right, the second inclined surface 14 will press down on the first inclined surface 13, that is, the second piece 12 presses down on the first piece 11, causing the connecting seat 3 to be pressed further down, so that the connecting seat 3 is further pressed against the base 2 during the sliding process, and the bag shell 100 between the two is vertically pressed and fixed. During the sliding of the slide 4 to the right, the first protrusion 15 on the outer wall of the connecting seat 3 and the second protrusion 16 on the groove wall of the slide 4 cooperate to make several triangular protrusions 17 on the first protrusion 15 engage in the slots 18 formed by the triangular protrusions 17 on the surface of the second protrusion 16, thereby achieving horizontal locking and fixing of the connecting seat 3. That is, while achieving vertical fixing of the sliding of the connecting seat 3, it also achieves horizontal locking of the connecting seat 3. The slide 4 itself limits the position, thus achieving triaxial fixing of the connecting seat 3 after it is slidably installed in place.

[0044] like Figure 9As shown, in the embodiment, the transverse sliding connecting seat 3 needs to use a certain force to push the transverse sliding of the connecting seat 3 to the right due to the structural arrangement of the first protrusion 15 and the second protrusion 16, and during the sliding process, the connecting seat 3 or the sliding groove 4 will be deformed, after the deformation, the several triangular protrusions 17 on the first protrusion 15 are clamped into the clamping groove 18 formed by the triangular protrusions 17 on the surface of the second protrusion 16, thereby limiting the connecting seat 3.

[0045] Embodiment 6:

[0046] The difference from embodiment 5 is that in addition to the structural features of the preceding embodiments, in the specific embodiments of the utility model, the edges of the triangular protrusions 17 on the first protrusion 15 are arranged to be offset to the other side direction along the sliding direction of the connecting seat 3, so that the several triangular protrusions 17 on the first protrusion 15 are distributed in a stepped manner; the edges of the triangular protrusions 17 on the second protrusion 16 are arranged to be offset in a stepped manner along the sliding direction of the connecting seat 3.

[0047] In order to facilitate the installation of the connecting seat 3, and further improve the locking effect of the installed connecting seat 3, as shown in Figure 8 , the edges of the triangular protrusions 17 on the first protrusion 15 are arranged to be offset to the other side direction along the sliding direction of the connecting seat 3, so that the several triangular protrusions 17 on the first protrusion 15 are distributed in a stepped manner, and as shown in Figure 7 , the edges of the triangular protrusions 17 on the second protrusion 16 are arranged to be offset in a stepped manner along the sliding direction of the connecting seat 3, so that the triangular protrusions 17 on the first protrusion 15 are squeezed and slide through the triangular protrusions 17 on the second protrusion 16 during the transverse pushing process of the connecting seat 3 to the right, and then slide into the clamping groove 18, and after sliding in, the sliding direction is convenient for continuing to push in, and it needs to exert more force to exit.

[0048] Embodiment 7:

[0049] The difference from embodiment 6 is that in addition to the structural features of the preceding embodiments, the first protrusion 15 and the several triangular protrusions 17 thereon are connected with the first block 11.

[0050] As shown in Figure 8 , the first block 11 on the connecting seat 3 needs to bear the downward pressure of the second inclined surface 14 of the second block 12, in order to improve the stress strength, and in the actual production process, in order to facilitate production and manufacturing, the structure for limiting is processed and formed together with the first block 11, that is, the first protrusion 15 and the several triangular protrusions 17 thereon are arranged to be connected with the first block 11, which can be integrally injection molded.

[0052] Different from the embodiment 6, in addition to comprising the structural features of the preceding embodiments, in the specific embodiments of the utility model, the upper surface of the base 2 is provided with at least one upward protrusion 19 for further clamping and fixing the luggage shell 100 between the base 2 and the connecting seat 3 which are pulled tight to each other.

[0053] As shown in Figures 1-2 , after the installation of the luggage shell 100, it is clamped and fixed between the connecting seat 3 and the base 2, and in order to improve the clamping and fixing effect of the luggage shell 100 after being pulled tight between the connecting seat 3 and the base 2, at least one upward protrusion 19 is arranged on the upper surface of the base 2 for further clamping and fixing the luggage shell 100 between the base 2 and the connecting seat 3 which are pulled tight to each other. The structure of the protrusion 19 can be a block-shaped protrusion, a wave-shaped protrusion or a strip-shaped protrusion, which can be selected according to the needs of use, and it needs to be noted that, as shown in Figure 3 , the surface of the protrusion 19 can also be provided with a friction surface according to the needs, such as stripes, or spots, or small particles, that is, to increase the relative static friction coefficient between the luggage shell 100.

[0054] Embodiment 8:

[0055] Different from the embodiment 7, in addition to comprising the structural features of the preceding embodiments, in the specific embodiments of the utility model, as shown in Figure 6 and Figure 7 , the protrusion 19 is arranged as at least four, and the four protrusions 19 are distributed on the upper surface of the base 2, which are symmetrical in pairs, that is, they can be uniformly stressed, and the structure is more stable.

[0056] Embodiment 9:

[0057] Different from the embodiment 8, in addition to comprising the structural features of the preceding embodiments, in the specific embodiments of the utility model, the base 2 is provided with a fastener assembly for further fixing after the connecting seat 3 is pulled and fixed, and the fastener assembly comprises a bolt fastener (not shown in the figure), a through hole 21 arranged on the base 2 and a fixing hole 22 arranged on the connecting seat 3.

[0058] As shown in Figure 4 and Figure 8 , in order to further improve the structural stability of the whole luggage handle after installation, a fastener assembly for further fixing after the connecting seat 3 is pulled and fixed is also arranged on the base 2, that is, a through hole 21 arranged on the base 2, a fixing hole 22 arranged on the connecting seat 3 and a bolt fastener, and at the same time in order to facilitate installation, the bolt fastener in this embodiment adopts a self-tapping screw with threads, so that the fixing hole 22 does not need to be processed as a threaded hole, which is an installation structure.

[0059] The bolt fastener can also be a threaded bolt, and if it is a threaded bolt, the fixing hole 22 needs to be processed into a threaded hole.

[0060] The connecting seat 3 is fixed by a bolt fastener after being slid laterally into place, and the final fixing is achieved by a bolt fastener locking structure, as shown in Figure 3 and Figure 4 This can improve the stability of the bag handle after installation, can withstand greater pulling force and force, and is suitable for use in more large-pulling-force scenarios.

[0061] Embodiment 10:

[0062] The difference from embodiment 9 is that, as shown in Figures 3-5 In addition to the structural features of the preceding embodiments, in the specific embodiments of the utility model, a first hole 31 is opened in the side wall of the connecting seat 3 away from the handle body 1, a second hole 32 is opened in the upper surface of the connecting seat 3 and communicates with the first hole 31, two curved connecting rods 101 are connected to the handle body 1, one end of the connecting rod 101 passes through the second hole 32 and the first hole 31 in sequence and is limited by the hole opening of the first hole 31, the second hole 32 is arranged to penetrate downward through the bottom of the connecting seat 3, the hole opening of the first hole 31 is smaller than the hole opening of the second hole 32, the middle part of the connecting rod 101 is smaller in width than the end part, the end part is larger in width than the hole opening of the first hole 31, and the hole opening of the second hole 32 is larger in width than the end part of the connecting rod 101.

[0063] In assembly, as shown in Figure 5 the end part of the connecting rod 101 connected to the handle body 1 is first passed downward through the bottom of the second hole 32, then the connecting rod 101 is raised upward so that the connecting rod 101 partially enters the first hole 31 and the end part is exposed from the first hole 31 and is limited by the hole opening of the first hole 31, that is, the connecting rod 101 is prevented from being pulled out of the first hole 31 and the second hole 32, then the bottom of the connecting seat 3 is passed into the bag shell 100, and in the bag shell 100, the base 2 is close to the connecting seat 3 so that the bottom of the connecting seat 3 is inserted into the sliding groove 4 of the base 2, as shown in Figure 9As shown, after insertion, the base 2 slides horizontally, causing the first inclined surface 13 on the connecting seat 3 to engage with the second inclined surface 14 located in the slide groove 4. As the connecting seat 3 continues to slide to the right, the second inclined surface 14 presses down on the first inclined surface 13, that is, the second block 12 presses down on the first block 11, causing the connecting seat 3 to press further down, thereby making the connecting seat 3 more closely attached to the base 2 during the sliding process and vertically pressing and fixing the bag shell 100 between the two. During the process of the connecting seat 3 sliding to the right along the slide groove 4, the first protrusion 15 on the outer wall of the connecting seat 3 and the second protrusion 16 on the groove wall of the slide groove 4 engage, causing several triangular protrusions 17 on the first protrusion 15 to be inserted into the slots 18 formed by the triangular protrusions 17 on the surface of the second protrusion 16, thereby achieving horizontal locking and fixing of the connecting seat 3. That is, while achieving vertical fixing of the sliding of the connecting seat 3, it also achieves horizontal locking of the connecting seat 3. The slide groove 4 itself limits the positioning, achieving triaxial fixing of the connecting seat 3 after it is slid into place.

[0064] The connecting rod 101 assembled into the slide 4 is as follows Figure 3 As shown, it can move in the slide 4, but is limited by the bottom of the slide 4 and the opening of the first hole 31. The width of the middle part of the connecting rod 101 is smaller than the width of the end, and the width of the end is larger than the width of the opening of the first hole 31. Even if it slides in the first hole 31 and the second hole 32, the end is limited. The width of the opening of the second hole 32 is larger than the width of the end of the connecting rod 101, which is used for the installation of the connecting rod 101.

[0065] In a specific embodiment of this utility model, a guide groove 33 for guiding the connecting rod 101 to slide is provided on the upper part of the inner wall of the second hole 32.

[0066] To facilitate pulling the handle body 1, such as Figure 9 As shown, a guide groove 33 is provided on the upper part of the inner wall of the second hole 32, so that the connecting rod 101 slides along the guide groove 33 during the process of being pulled outward by the handle body 1, which can reduce wear and improve service life.
