[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] The present application will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to explain the relevant utility model and are not intended to limit the utility model. It should also be noted that, for ease of description, only portions relevant to the relevant utility model are shown in the accompanying drawings. It should be noted that the embodiments and features in the embodiments of this application may be combined with each other unless there is a conflict.

[0028] The utility model provides a tightening device for a car map bag covering a leather case, such as Figures 1 to 3 As shown, it includes a backplane carrier 1 with a backplane loading slot 10, a positioning carrier 2 is provided at one end of the backplane carrier 1, and a top clamping mechanism 3 is provided at the other end, and a group of opposite side edges of the backplane carrier 1 are respectively provided with side clamping mechanisms 4 arranged adjacent to the positioning carrier 2.

[0029] The top clamping mechanism 3 includes a top clamp 30 with horizontal tensile displacement, and the top clamp 30 includes two top clamps 31 with vertical clamping displacement. A serration portion 32 is provided on the clamping surface of any top clamp.

[0030] The side clamping mechanism 4 includes a side clamp 40 with horizontal stretching displacement. The side clamp 40 includes two side clamps 41 with vertical clamping displacement. A clamping serrated surface 42 is provided on the clamping surface of any side clamp.

[0031] Specific implementation process and principle description:

[0032] First, the positioning carrier plate 2 is used in an open manner to realize pre-positioning during the upper leather sleeve, and the positioning carrier plate 2 is used as a positioning reference for the upper leather sleeve.

[0033] After the upper leather sleeve is loaded, one end of the upper leather sleeve is clamped between the top clamping plates 31, the sawtooth part 32 on the top clamping plates 31 is used for stable clamping and locking, and the clamping sawtooth surface 42 of the side clamping plate 41 is used for clamping and locking.

[0034] After the upper leather sleeve is clamped, the upper leather sleeve is tightened through the horizontal displacement of the top clamping fixture 30 and the two side clamping fixtures 40, at this time, the external pickup mechanism picks up the back plate to perform crimping on the top of the upper leather sleeve, and after crimping, the upper leather sleeve and the back plate are embedded in the back plate loading groove 10 of the back plate carrier 1, thereby realizing the covering operation of the tightened upper leather sleeve.

[0035] In one specific embodiment, the positioning carrier plate 2 is provided with a plurality of positioning pins 20.

[0036] Specifically, the upper leather sleeve has a certain fixed specification, and a positioning hole is arranged on the upper leather sleeve, so that the upper leather sleeve can be positioned and loaded through cooperation of the positioning hole and the positioning pin 20.

[0037] Of course, a chuck with a locking pin column, a clamping plate with a positioning mark, and other structures that can realize the positioning and locking of the upper leather sleeve during loading are also possible, as long as they are within the protection scope of the present case.

[0038] In one specific embodiment, the top clamping mechanism 3 includes a horizontal carrier 33 with horizontal displacement, the horizontal carrier 33 is provided with a top flange carrier plate 34 with lifting displacement, and the top flange carrier plate 34 is provided with a top clamping fixture 30.

[0039] Specifically, after the back plate is crimped in place, the top flange carrier plate 34 is lifted, at this time, due to the clamping and tightening of the top clamping fixture 30 on the upper leather sleeve, the edge of the top flange carrier plate 34 can perform flange work on the upper leather sleeve, so that the upper leather sleeve is reliably flanged and adhered to the periphery of the back plate after flanging, and the flanged and covered quality is reliable and stable.

[0040] In one specific embodiment, the side clamping mechanism 4 includes a horizontal slide 43 with horizontal displacement, the horizontal slide 43 is provided with a side flange carrier plate 44 with lifting displacement, and the side flange carrier plate 44 is provided with a side clamping fixture 40.

[0041] The embodiment of the side clamping mechanism 4 is similar to that of the top clamping mechanism 3, and can realize flange covering of the side, thereby improving the quality.

[0042] In one specific embodiment, the side flange carrier plate 44 is provided with a folded edge 440 extending into the back plate loading groove.

[0043] Specifically, the top is a long-side flange, so the edge of the top flange carrier plate 34 is flush with the back panel carrier groove. During the process of pressing the back panel down, it plays a role in guiding the flange requirement. After being pressed into place, its lifting and lowering displacement is used to level the flange, making the flange effect better.

[0044] The side is a short flange, and the two sides are relatively matched. During the downward movement of the back panel, it may have a certain deviation. Through the design of the folded edge 440, it plays a guiding role. At the same time, before the back panel is pressed into place, the rising flange is smoothed. In this way, after the back panel is in place, the flange effect is better, that is, the folded edge 440 can be elastically deformed under pressure, and play an elastic fit and upward smoothing function.

[0045] In a specific embodiment, a corner end flanging mechanism 5 is provided between the top clamping mechanism 3 and any adjacent side clamping mechanism 4 .

[0046] Specifically, the corner end flanging mechanism 5 includes a flanging slide 51 with horizontal displacement and a corner end flanging plate 52 with lifting displacement arranged on the flanging slide 51 .

[0047] The top flange carrier plate 34 and the side flange carrier plate 44 can realize the flange after tightening. When some back panels with curved transition edges are covered, corner wrinkles are prone to occur. Therefore, the design of the corner flange plate 52 is adopted, which can realize the contact and flange lifting of the corner end, thereby ensuring the covering quality of the leather case corner end.

[0048] In a specific embodiment, the free end of the corner flange plate 52 is provided with an extended bent edge 520. The extended bent edge 520 plays the role of elastically abutting and lifting the flange to smooth it out, without causing over-pressure damage to the leather case.

[0049] The above description demonstrates that the present invention, a tightening device for a car map pocket cover, satisfies the requirements for positioning and tightening the cover. It offers reliable tightening and locking, virtually eliminating the risk of loosening or damage to the cover during downward pressure after tightening. It also provides stable and reliable operation. It can also perform flanging and smoothing operations, meeting requirements for flanging and smoothing edges at the ends, sides, and corners, significantly improving product quality. The overall design is simple and ingenious, with reliable coordination and ease of manufacture and widespread application.

[0051] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
