Description

Technical Field

[0001] The utility model relates to the field of daily necessities, in particular to a zipper piece limiting lock structure and a suitcase. Background Art

[0002] With the development of society, economic progress and the improvement of people's living standards, people's travel frequency has gradually increased. When traveling, people generally carry bags to store their belongings. In order to protect privacy from being peeped and to facilitate taking things, bags are generally opened and closed with zippers.

[0003] The zipper is a kind of closure device that is commonly used in luggage nowadays. Generally, the zipper has two chain straps, which are closed or separated by zipper heads. The zipper head is provided with a zipper piece. When the two zipper heads close the chain straps together, the two zipper heads need to be fixed by the zipper piece to prevent the zipper from being opened. The existing zipper piece is buckled on the column position. Because the distance between the zipper piece and the column position is fixed, the assembly position of the lock is required to be high, and the zipper piece is usually not buckled smoothly (such as Figure 1 shown). Summary of the invention

[0004] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the utility model is to provide a zipper piece limit lock structure. The new zipper piece fixing method has a simple structure, improved fault tolerance of buckling, and low assembly accuracy requirements for the lock.

[0005] The purpose of the utility model is achieved through the following technical solutions: a zipper piece limit lock structure, including a lock seat and a pressure block, the side of the pressure block is provided with an elastic clamping arm, the lock seat is provided with a groove, the side wall of the groove is provided with a convex block, the zipper piece is clamped between the convex block and the elastic clamping arm, a pressure block mounting seat is provided in the groove, the pressure block is mounted on the pressure block mounting seat, and the zipper piece is provided with a long strip clamping groove. Since the long strip clamping groove is provided on the zipper piece, the installation position of the lock seat has a certain position selectivity, as long as the clamping groove can be clamped by the elastic clamping arm, the installation accuracy requirement for the lock is greatly reduced.

[0006] As an improvement of the zipper piece position-limiting lock structure of the utility model, the position where the protrusion and the elastic clamping arm clamp the zipper piece is the clamping groove. The clamping groove can cooperate with the protrusion and the elastic clamping arm to limit the zipper piece.

[0007] As an improvement of the zipper piece limit lock structure of the utility model, the cross section of the clamping groove is arc-shaped, and the outer side of the elastic clamping arm is provided with an arc-shaped protrusion, which can be embedded in the arc-shaped clamping groove. The arc-shaped protrusion can cooperate more closely with the arc-shaped clamping groove to prevent the zipper piece from moving up and down.

[0008] As an improvement of the zipper piece position-limiting lock structure of the utility model, the surface of the protrusion is arc-shaped, so that the zipper piece can be easily inserted between the protrusion and the arc-shaped protrusion from the side.

[0009] As an improvement of the zipper piece limiting lock structure of the utility model, the pressure block mounting seat is provided with a mounting groove, and the side of the mounting groove is provided with two corresponding notches, the pressure block is embedded in the mounting groove, and the elastic clamping arm extends from the notch.

[0010] As an improvement of the zipper piece limit lock structure of the utility model, two corresponding sliders are provided on the inner side wall of the installation groove, and the positions corresponding to the sliders on both sides of the pressure block are provided with slide grooves, and when the pressure block is embedded in the installation groove, the slider slides in along the slide groove. The slider and the slide groove cooperate to limit the left and right movement position of the pressure block, so that the distance between the two elastic clamping arms and the protrusion is the same.

[0011] As an improvement of the zipper piece limiting lock structure of the utility model, it also includes a screw, which penetrates from the bottom of the lock seat and is threadedly connected with the pressing block.

[0012] As an improvement of the zipper piece limiting lock structure of the utility model, the elastic clamping arms are provided in two and are respectively provided at the bottom of both sides of the pressing block. The zipper piece consists of two pieces, and each elastic clamping arm is used to clamp and fix a zipper piece.

[0013] Another object of the utility model is to provide a suitcase, comprising a case body and a case cover, wherein edges of the case body and the case cover are both provided with zipper strips, the zipper piece is connected to a zipper head, the zipper head is used to close the zipper strip, the zipper piece limiting lock structure is provided on the case cover, and the zipper piece limiting lock structure is used to fix the zipper piece.

[0014] The beneficial effect of the utility model is that elastic clamping arms are respectively arranged on both sides of the pressure block, and the elastic clamping arms can clamp the zipper sheet together. Since a long strip-shaped clamping groove is arranged on the zipper sheet, the installation position of the lock seat has a certain position selectivity. As long as the clamping groove can be clamped by the elastic clamping arm, the installation accuracy requirement for the lock is greatly reduced. BRIEF DESCRIPTION OF THE DRAWINGS
