[0014] Furthermore, the fixed rail also extends forward and backward; and the front and rear sides of the fixed rail are respectively connected and fixed to the fixing seats arranged on the front and rear sides of the inner cavity side walls of the box body.

[0015] Furthermore, the upper and lower sides of the fixing seat respectively have locking plates, which are locked to the side walls of the inner cavity of the box body. A fixing plate protrudes between the two locking plates toward the fixed rail, and the fixing plate is spaced from the inner side wall of the box body. A fixing buckle is provided on the fixing plate, which is connected and fixed to the fixing rail through hole on the fixing rail.

[0016] Furthermore, the fixing plate is provided with a fixing plate through hole; the fixing buckle is a fixing rivet, the rivet head of the fixing rivet is limited to one side of the fixing plate, the rivet column of the fixing rivet passes through the fixing plate through hole and the fixing rail through hole in sequence, and the passed part is provided with an annular groove, and a retaining ring is clamped on the annular groove, and the retaining ring and the fixing rivet cooperate to fix the fixing rail on the fixing plate.

[0017] Furthermore, the diameter of the portion of the rivet column of the fixing rivet that does not pass through the through hole of the fixing plate is larger than the diameter of the through hole of the fixing plate; and the retaining spring presses and fixes the fixing rail and the fixing plate.

[0018] Furthermore, the drawer includes a drawer panel and a drawer tray connected front and back; the drawer tray is slidably assembled at the front opening of the box body, and the drawer panel movably closes the front opening;

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0036] like Figures 1 to 9 As shown, an improved slide rail structure of a cash box of the utility model comprises a box body 1 and a drawer 2, wherein two sides of the drawer 2 are fixed to two sides of an inner cavity 11 of the box body 1 through slide rails 3 respectively.

[0037] like Figure 6 The slide rail 3 includes a fixed rail 31 and a sliding rail 32 that slide with each other; the sliding cooperation between the fixed rail 31 and the sliding rail 32 is a prior art, and the specific assembly structure of the two will not be repeated here.

[0038] The fixed rail 31 is connected to the inner cavity side wall 111 of the box body 1, and the sliding rail 32 is connected to the drawer side wall 21; a sliding rail 3 is respectively provided on the left and right sides of the drawer 2 in this embodiment.

[0039] like Figures 3 to 5 The sliding rail 32 extends horizontally frontward and rearward, and the front end of the sliding rail 32 is provided with a quick-connect hole 33 that passes through left and right, so that the front end of the sliding rail 32 can be quickly connected to the drawer 2.

[0040] The quick-connect hole 33 includes a mounting hole 331 , a connecting groove 332 and a limiting groove 333 which are sequentially distributed front to back.

[0041] The diameter of the mounting hole 331 is larger than the width of the connecting groove 332 and the limiting groove 333; the connecting groove 332 extends forward and backward to connect the front mounting hole 331 and the rear limiting groove 333; the limiting groove 333 extends upward and downward, and the upper end 3331 of the limiting groove 333 is higher than the connecting groove 332, while the lower end 3332 of the limiting groove 333 is lower than the mounting hole 331;

[0042] A quick-connect buckle 22 protrudes from the front end of the drawer side wall 21. The quick-connect buckle 22 includes a limiting head 221 at the outer end. The limiting head 221 is used to pass through the mounting hole 331 of the quick-connect hole 33 and be clamped in the lower end 3332 of the limiting groove 333 of the quick-connect hole 33.

[0043] The locket 33 is engaged with the drawer 2 and the locking nut 331 so that the drawer 2 can be locked with the locking nut 332.

[0044] If the drawer 2 is lifted upward during the pulling process, the quick-connect buckle 22 will slide up and down along the limiting groove 333. However, since the upper end 3331 of the limiting groove 333 is higher than the connecting groove 332, unless the quick-connect buckle 22 is intentionally aligned with the connecting groove 332, the lifting action occurring during the normal pulling of the drawer 2 will not cause the quick-connect buckle 22 to return to the connecting groove 332 and the mounting hole 331, thereby preventing the quick-connect buckle 22 and the quick-connect hole 33 of the drawer 2 from being separated, thereby improving the reliability of the product and ensuring smooth pulling of the drawer 2.

[0045] like Figure 5As shown, specifically, the quick-connect buckle 22 of this embodiment is in a "T" shape, and includes a circular limiting head 221 located at the outer end and a connecting portion 222 connected between the limiting head 221 and the drawer side wall 21; at the same time, the diameter of the limiting head 221 is not greater than the diameter of the mounting hole 331, and is greater than the width of the connecting groove 332 and the limiting groove 333; the diameter of the connecting portion 222 is smaller than the diameter of the limiting head 221, and is smaller than the width of the connecting groove 332 and the limiting groove 333. Therefore, the limiting head 221 plays a limiting role, and the connecting portion 222 can slide in the connecting groove 332 and the limiting groove 333.

[0046] Of course, the limiting head 221 is not limited to a circle, and can be an ellipse, a square, etc.

[0047] like Figure 5 and Figure 8 In this embodiment, the quick-connect buckle 22 is used to connect rivets as an example.

[0048] The front end of the drawer side wall 21 is provided with a drawer through hole 211; the quick-connect buckle 22 is in the shape of an independent rivet; the connection part 222 of the quick-connect buckle 22 is further provided with a fixing part 223 on the side away from the limiting head 221, the fixing part 223 passes through the drawer through hole 211, and the part of the fixing part 223 passing through the drawer through hole 211 is provided with a fixing part annular groove 2231, and a retaining ring a is clamped on the fixing part annular groove 2231, and the retaining ring a fixes the quick-connect buckle 22 to the drawer through hole 211 of the drawer side wall 21. Thus, the production and assembly of the connecting buckle can be facilitated.

[0049] like Figures 3 to 5 The top of the drawer side wall 21 extends toward the sliding rail 32 on the same side with an upper flange 212; when the quick-connect buckle 22 is clamped to the lower end 3332 of the limiting groove 333, the upper flange 212 is placed on the top of the sliding rail 32. The sliding rail 32 can also be "C" shaped.

[0050] Thereby, the assembly effect of the drawer 2 and the sliding rail 32 can be improved, and the stability of the cooperation between the two can be improved.

[0051] Another example Figure 6 and Figure 7 and the front and rear sides of the fixed rail 31 are respectively connected and fixed to the fixing seat 12 disposed on the front and rear sides of the inner cavity side wall 111 of the box body 1.

[0052] In this embodiment, the box body 1 may include an upper cover 13 and a bottom plate 14 , and the upper cover 13 and the bottom plate 14 are combined up and down to form an inner cavity 11 of the box body 1 .

[0053] In this embodiment, the fixing seat 12 can be in a "J" shape, and the upper and lower sides of the fixing seat 12 respectively have locking plates 121, and the locking plates 121 are locked to the inner cavity side walls 111 of the box body 1. A fixing plate 122 protrudes between the two locking plates 121 toward the fixed rail 31. In this embodiment, the upper and lower ends of the fixing plate 122 can be connected to the locking plate 121 through a horizontal plate 123 respectively.

[0054] The fixing plate 122 is spaced apart from the inner cavity side wall 111 of the box body 1 , and a fixing buckle 124 is provided on the fixing plate 122 , and the fixing buckle 124 is connected and fixed to the fixing rail through hole 311 on the fixing rail 31 .

[0055] The fixing seat 12 is provided, and the fixing seat 12 and the sliding rail 32 can be fixed in advance, and then the fixing seat 12 is connected to the box body 1, so as to facilitate the matching connection between the sliding rail 32 and the box body 1.

[0056] Specifically, the fixing plate 122 is provided with a fixing plate through hole 1221; the fixing buckle 124 can be an independent fixing rivet, the rivet head 1241 of the fixing rivet is limited to one side of the fixing plate 122, the rivet column 1242 of the fixing rivet passes through the fixing plate through hole 1221 and the fixing rail through hole 311 in sequence, and the passed part is provided with an annular groove 1243, and a retaining spring a is clamped on the annular groove 1243, and the retaining spring a cooperates with the fixing buckle 124 to fix the fixing rail 31 on the fixing plate 122.

[0057] Likewise, by configuring the fixing buckle 124 as a fixing rivet structure, the assembly of the fixing rail 31 can be facilitated.

[0058] Furthermore, the diameter of the portion of the rivet column 1242 of the fixing rivet that does not pass through the fixing plate through hole 1221 is larger than the diameter of the fixing plate through hole 1221; and the clamping spring a presses and fixes the fixing rail 31 and the fixing plate 122, thereby ensuring that the fixing rail 31 is stably connected to the fixing seat 12 without shaking.

[0059] For example Figure 2 , Figure 8 and Fig. 9 As shown, the drawer 2 of this embodiment includes a drawer panel 23 and a drawer tray 24 connected front and back; the drawer tray 24 is slidably assembled at the front opening 15 of the box body 1, and the sliding rail 32 can be connected to the side wall of the drawer tray 24. The drawer panel 23 movably closes the front opening 15;

[0060] At least one annular frame 241 is disposed in the drawer tray 24 . In this embodiment, two annular frames 241 spaced apart from each other are disposed in the drawer tray 24 . The annular frames 241 can be locked and fixed in the drawer tray 24 .

[0061] The annular frame 241 protrudes from the inner bottom surface of the drawer tray 24 , and a storage area 242 is formed in the annular frame 241 ; the storage area 242 can be used to store checks, cash, etc.

[0062] A cash tray 25 is further provided inside the drawer tray 24, and the cash tray 25 can be used to store various cash, change, etc.; the cash tray 25 is set above the annular frame 241, and there is a gap between the front side of the cash tray 25 and the front side of the annular frame 241, and the gap is a channel 243 connected to the storage area 242; the drawer panel 23 is provided with a panel notch 231 corresponding to the channel 243.

[0063] Thus, the storage area 242 can be hidden under the cash tray 25 , and the corresponding checks can be inserted into the panel slot 231 and stored in the storage area 242 through the channel 243 .

[0064] Another example Fig. 9 As shown, the front side 2411 of the annular frame 241 is closely attached to the front end of the drawer tray 24, and the inner side of the front side 2411 may be provided with an inclined surface 2412, and the bottom of the cash tray 25 corresponding to the inclined surface 2412 may be provided with an arc surface 251; the channel 243 is formed between the inclined surface 2412 and the arc surface 251. Therefore, the bills such as checks inserted through the panel notch 231 can slide smoothly into the storage area 242 under the guidance of the inclined surface 2412 and the arc surface 251, preventing the checks from being blocked in the channel 243, thereby improving the user experience.
