Description

Technical Field

[0001] This utility model relates to the field of voucher binding technology, specifically a voucher binding clamping and positioning device. Background Technology

[0002] Accounting voucher binding refers to binding various original receipts and expenditures within a certain period into a book. When binding vouchers, the organized vouchers need to be aligned with the upper left corner as a reference, fixed with clips, and then punched and bound using a binding device.

[0003] In practice, the contact surface of the clips that hold the vouchers is small and needs to avoid the punching positions on the vouchers, which results in the punching positions on the vouchers being relatively loose. When punching, the vouchers are prone to misalignment, which ultimately leads to uneven binding. In order to avoid this situation, a clamping and positioning device for voucher binding is provided. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping and positioning device for voucher binding in order to solve the problems mentioned above.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a clamping and positioning device for binding vouchers, comprising a base plate assembly and a cover plate assembly, wherein the base plate assembly and the cover plate assembly cooperate with each other to provide sorting, limiting and clamping fixation for the vouchers;

[0006] The base plate assembly includes a base plate, positioning blocks, locking spring blocks, and ratchet teeth. The two sets of positioning blocks are respectively fixed at two diagonal edges on the upper surface of the base plate, and the two sets of positioning blocks are used to provide positioning for the voucher.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-3 In this embodiment of the utility model, a clamping and positioning device for binding vouchers includes a base plate assembly 1 and a cover plate assembly 2. The base plate assembly 1 and the cover plate assembly 2 cooperate with each other to provide sorting limit and clamping fixation for the voucher 4.

[0021] The base plate assembly 1 includes a base plate 101, positioning blocks 102, locking spring blocks 103, and ratchet 104. The two sets of positioning blocks 102 are respectively fixed at two diagonal edges on the upper surface of the base plate 101. The two sets of positioning blocks 102 are used to provide positioning for the voucher 4.

[0022] Two locking spring blocks 103 are respectively fixed to the other two diagonal edges of the upper surface of the base plate 101, and ratchet 104 is integrally formed on the side of the locking spring block 103.

[0023] The cover plate assembly 2 includes a pressure plate 201 and a T-shaped locking block 202. The two T-shaped locking blocks 202 are respectively fixed to the two diagonal sides of the pressure plate 201. The pressure plate 201 is sleeved on the outside of the positioning block 102 through the T-shaped locking blocks 202. The two mating edges of the pressure plate 201 away from the T-shaped locking blocks 202 are engaged with the ratchet 104 on the locking spring block 103 to achieve clamping and fixing of the voucher 4 between the pressure plate 201 and the base plate 101.

[0024] The outer wall dimension of the base plate 101 is larger than the outer wall dimension of the voucher 4, and the edge of the T-shaped card block 202 is aligned with the edge of the base plate 101;

[0025] The base plate 101 and the pressure plate 201 are provided with binding mark holes 3 near the two sets of positioning blocks 102. The binding mark holes 3 on the base plate 101 and the pressure plate 201 are aligned vertically.

[0026] In this embodiment, the clamping and positioning device is used as follows:

[0027] First, place the base plate assembly 1 on the table, then place the organized voucher 4 on the upper surface of the base plate 101, with the corner of the voucher 4 to be bound close to the positioning block 102.

[0028] Next, take out the cover plate assembly 2, align the two T-shaped locking blocks 202 with the two sets of positioning blocks 102 respectively, and then put the pressure plate 201 on the outside of the positioning block 102 through the T-shaped locking blocks 202 and press it downward, so that the pressure plate 201 initially contacts the voucher 4. During this process, the pressure plate 201 is pressed against the ratchet 104 on the locking spring block 103, causing the locking spring block 103 to deform. When the edge of the pressure plate 201 is aligned with the middle tooth groove of the two ratchet 104, the locking spring block 103 resets under its own elastic force and locks with the pressure plate 201. Repeat this process to achieve the one-way self-locking of the pressure plate 201.

[0029] After the pressure plate 201 is initially completed, the device can be erected as a whole, and the two edges of the base plate 101 near the positioning block 102 can be aligned with the table and struck in turn to achieve the effect of shaking and tidying up the voucher 4, so that the corners of the voucher 4 to be bound are automatically aligned (it should be noted that in this state, the pressure plate 201 does not completely press the voucher 4, and the voucher 4 can be shaken).

[0030] After the corners of the document 4 to be bound are aligned, press the pressure plate 201 further to make the pressure plate 201 press the document 4 completely. Then the entire device can be transferred to the binding device for subsequent binding operations.

[0031] The binding mark hole 3 provides positioning for binding and punching, making it easier to determine the punching position. It should also be noted that the diameter of the binding mark hole 3 is larger than the outer diameter of the punch of the binding device, so it will not interfere with the binding operation of the binding device.

[0032] Please refer to this carefully. Figures 1-3 The top of the locking spring block 103 is integrally formed with a buckle groove 105, and the corner of the pressure plate 201 near the locking spring block 103 is formed with an avoidance notch 204.

[0033] The upper surface of the pressure plate 201 has several matrix-distributed weight-reducing grooves 203.

[0034] In this embodiment: the latching groove 105 facilitates the locking spring block 103 to be latched and unlocked, and the avoidance notch 204 is used to prevent the pressure plate 201 from colliding with the hand unlocking the locking spring block 103;

[0035] The pressure plate 201 can be made of metal to ensure a stable pressing state on the voucher 4. The weight reduction groove 203 can reduce the weight of the pressure plate 201 and make it easier to handle and use.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
