Description

Technical Field

[0001] This utility model relates to a double sliding buckle structure for the battery cover of a POS machine, belonging to the field of POS machines. Background Technology

[0002] A POS terminal is a multi-functional terminal that, when installed in merchant locations and connected to a computer network, enables automatic electronic fund transfers. It supports functions such as spending, pre-authorization, balance inquiry, and transfers, and is safe, fast, and reliable to use.

[0003] During the use of a POS machine, there are many ways to open and close the battery cover. For example, patent application CN202221993434.2, entitled "A Sliding Buckle Structure for a POS Machine Battery Cover," discloses a structure including: a housing, a battery cover, and a sliding buckle assembly. The housing has a battery slot, and the battery cover closes to the battery slot. The sliding buckle assembly includes a guide block, a connecting block, a fixing block, a limiting block, and a locking block. The connecting block is connected to the guide block and the fixing block. The locking block connects the connecting block and the fixing block. The limiting block is installed on both sides of the fixing block, with its outer side protruding outwards. A limiting groove is provided between the inner side of the limiting block and the locking block. The battery cover has an installation groove with an opening. A sliding groove is provided on the back of the installation groove. The sliding buckle assembly is slidably connected to the battery cover by installing the guide block in the installation groove, the connecting block in the opening, and the ends of the fixing block and the limiting block in the sliding groove. The housing has a slot, and the sliding buckle assembly is connected to the housing by installing the rear end of the locking block in the slot. This invention is easy to assemble and makes the machine body more beautiful and compact.

[0004] In practical applications, the following situations may occur: when the fit tolerance of the sliding buckle elastic arm is lower than the limit, coupled with daily wear during use, the fit between the sliding buckle and the battery cover becomes loose, and the operating force decreases accordingly. This may cause the sliding buckle to not be in the limit position when locked. Alternatively, if the fit dimensions of the elastic arms on both sides of the sliding buckle are in series, and one side of the elastic arm breaks, the other side of the elastic arm will also fail, causing the sliding buckle to loosen and fall off abnormally.

[0005] Therefore, in view of the above situation, a double-sliding buckle structure for the battery cover of a POS machine with a double-sliding structure is proposed to solve the problem of abnormal detachment caused by loosening of the sliding buckle. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a double sliding buckle structure for the battery cover of a POS machine.

[0007] This utility model is implemented as follows: A POS machine battery cover double sliding buckle structure includes a housing, a battery slot disposed in the middle of the housing, and a battery cover that fits onto the end of the battery slot. It also includes a sliding buckle assembly, which comprises a guide block, a locking block and two elastic arms forming the sliding cover, as well as a mounting groove, a slide rail, two movable openings and two second limiting blocks formed on the battery cover; The top surface of the locking block is fixedly connected to the bottom surface of the guide block. Two elastic arms are fixedly disposed on both sides of the front end of the locking block, and the thickness h1 of the elastic arms is less than the thickness h2 of the locking block, so that there is a sliding groove between the top surface of the elastic arm and the bottom surface of the guide block that slides with the slide rail. The outer side of the free end of the elastic arm protrudes outward, so that when the sliding cover is slidably connected to the battery cover, the elastic arm constrains the locking block from the outside. The rear end of the upper surface of the battery cover is provided with a mounting groove for mounting the sliding cover. The inner wall of the mounting groove is provided with a slide rail. A second limiting block that is symmetrical to each other is fixed on the outer side of the slide rail. A movable opening is opened on the slide rail corresponding to the second limiting block so that when the sliding cover is slidably connected to the battery cover, the second limiting block is offset in position and restrains the locking block from the inside.

[0008] As a further improvement, the housing is provided with a slot that mates with the rear end of the locking block, and the connection between the sliding cover and the housing is achieved by installing the rear end of the locking block into the slot.

[0009] As a further improvement, the front ends of the guide block and the locking block are arched.

[0010] As a further improvement, a finger groove is provided at the front end of the upper surface of the guide block.

[0011] As a further improvement, the upper surface of the guide block is provided with a plurality of anti-slip ribs perpendicular to the sliding direction at the rear end.

[0012] As a further improvement, during the insertion of the rear end of the locking block into the slot, a plurality of protrusions are provided in the housing at the position in contact with the lower surface of the locking block.

[0013] As a further improvement, the inner wall of the mounting groove corresponding to the elastic arm is provided with several arc-shaped protrusions facing the center of the mounting groove.

[0014] As a further improvement, the front end of the lower surface of the battery cover is provided with two pins, the rear end of the lower surface of the battery cover is provided with two limiting ribs, the front end of the battery slot is provided with two insertion holes that match the pins, and the front end of the battery slot is provided with two limiting holes that match the limiting ribs; the battery cover and the battery slot are closed by inserting the pins into the insertion holes and the limiting ribs into the limiting holes.

[0015] The beneficial effects of this utility model are: This utility model uses an elastic arm to constrain the sliding cover from the outside, and uses symmetrical second limiting blocks to constrain the sliding cover from the inside. The two sets of constraint structures constrain the sliding cover together, which has the advantages of stable force value and good fatigue resistance. It complements the characteristics of the external buckle cantilever elastic arm. The design of the double buckle mechanism can effectively avoid the problem of buckle failure caused by the failure of a single buckle mechanism. Attached Figure Description

[0029] Reference Figures 1 to 9 As shown, this embodiment provides a specific implementation of a double sliding buckle structure for a POS machine battery cover, including a housing 10, a battery slot 20 disposed in the middle of the housing 10, and a battery cover 30 that covers the end of the battery slot 20. It also includes a sliding buckle assembly 40, which includes a guide block 401, a locking block 402 and two elastic arms 403 that form the sliding cover, as well as a mounting groove 404, a slide rail 405, two movable openings 406 and two second limiting blocks 407 formed on the battery cover 30. The top surface of the locking block 402 is fixedly connected to the bottom surface of the guide block 401. Two elastic arms 403 are fixedly disposed on both sides of the front end of the locking block 402, and the thickness h1 of the elastic arm 403 is less than the thickness h2 of the locking block 402, so that there is a groove between the top surface of the elastic arm 403 and the bottom surface of the guide block 401 that slides and engages with the slide rail 405. The outer side of the free end of the elastic arm 403 protrudes outward, so that when the sliding cover is slidably connected to the battery cover 30, the elastic arm 403 constrains the locking block 402 from the outside. The rear end of the upper surface of the battery cover 30 is provided with a mounting groove 404 for mounting the sliding cover. The inner wall of the mounting groove 404 is provided with a slide rail 405. A second limiting block 407 that is symmetrically positioned is fixed on the outer side of the slide rail 405. A movable opening 406 is opened on the slide rail 405 corresponding to the second limiting block 407, so that when the sliding cover is slidably connected to the battery cover 30, the second limiting block 407 is offset in position, thus constraining the locking block 402 from the inside.

[0030] Furthermore, the inner wall of the mounting groove 404 corresponding to the elastic arm 403 is provided with several arc-shaped protrusions facing the center of the mounting groove 404.

[0031] The housing 10 is provided with a slot 101 that cooperates with the rear end of the locking block 402. The connection between the sliding cover and the housing 10 is achieved by installing the rear end of the locking block 402 into the slot 101.

[0032] The above description details the essential technical features of this utility model in solving the technical problem. It uses an elastic arm 403 to constrain the sliding cover from the outside, and a symmetrical second limiting block 407 to constrain the sliding cover from the inside. The two sets of constraint structures constrain the sliding cover together, which has the advantages of stable force and good fatigue resistance. It complements the characteristics of the external buckle cantilever elastic arm. The design of the double buckle mechanism can effectively avoid the problem of buckle failure caused by the failure of a single buckle mechanism.

[0033] In this embodiment, the front ends of the guide block 401 and the locking block 402 are arched. The arched structure is to reduce space and reduce weight and cost while still achieving the desired function.

[0034] In this embodiment, a finger groove 411 is provided at the front end of the upper surface of the guide block 401. The function of the finger groove 411 is to increase friction and facilitate sliding.

[0035] In this embodiment, the upper surface of the guide block 401 is provided with a plurality of anti-slip ribs 412 perpendicular to the sliding direction at the rear end, which increases the friction and facilitates sliding.

[0036] In this embodiment, during the process of inserting the rear end of the locking block 402 into the slot 101, a plurality of protrusions are provided at the position in the housing 10 that contacts the lower surface of the locking block 402 in order to increase friction and improve the feel.

[0037] In this embodiment, the front end of the lower surface of the battery cover 30 is provided with two pins 301, the rear end of the lower surface of the battery cover 30 is provided with two limiting ribs, the front end of the battery slot 20 is provided with two insertion holes 201 that match the pins, and the front end of the battery slot 20 is provided with two limiting holes that match the limiting ribs; the battery cover 30 and the battery slot are closed by the pins 301 being inserted into the insertion holes 201 and the limiting ribs being inserted into the limiting holes. The purpose of the pin 301 and the socket 201 is to prevent the battery cover 30 from moving upward and to fix the front end of the battery cover 30. The purpose of the limiting bone and the limiting hole is to prevent the battery cover 30 from moving left and right and to fix the rear end of the battery cover 30.
