[0037] Please refer to Figures 1 to 3 , Figure 1 , Figure 2 which is a schematic structural diagram of a connecting device, a baffle plate module and a label printer in an embodiment of the present utility model. The connecting device is arranged between the baffle plate 1 and the rack 2, and includes a first connecting body 3, a second connecting body 4 and at least one clamping member 5. The first connecting body 3 is connected to any one of the baffle plate 1 or the rack 2. The second connecting body 4 is arranged opposite to the first connecting body 3 and is connected to the other one of the rack 2 or the baffle plate 1, and can extend and be arranged on the first connecting body 3. The clamping member 5 is connected to the second connecting body 4 and is detachably connected to the first connecting body 3, and is used to detachably connect the second connecting body 4 to the first connecting body 3 and detachably connect the rack 2 to the baffle plate 1.

[0038] In this application, a connecting device is arranged between the baffle plate 1 and the rack 2, wherein the first connecting body 3 is connected to any one of the baffle plate 1 or the rack 2, the second connecting body 4 is arranged opposite to the first connecting body 3 and is connected to the other one of the rack 2 or the baffle plate 1, and at least one clamping member 5 is connected to the second connecting body 4 and can be detachably connected to the first connecting body 3, and is used to detachably connect the second connecting body 4 and the rack 2 to the first connecting body 3 and the baffle plate 1.

[0039] Compared with the prior art, the baffle 1 and the rack 2 are separately arranged and connected in a detachable manner. Not only are they three-dimensionally arranged in terms of structure, but also by using PA+30%GF material in terms of material, the strength problems of the two parts of the baffle 1 and the rack 2 can be effectively solved, avoiding deformation of the baffle 1 or the rack 2 parts, and being able to solve the problem that in the prior art, due to the injection molding of the baffle 1 and the rack 2 and the structural space limitation, the structural strength of the baffle 1 or the rack 2 is insufficient, resulting in easy deformation of the baffle 1 or the rack 2, and then solving the problem of left-right offset in printing caused by part deformation.

[0040] Furthermore, usually, in order to save costs, the baffle 1 and the rack 2 of current common label printers are one part. Due to injection molding and structural space limitations, the structural strength of the baffle 1 is often insufficient and it is easy to deform, and the baffle 1 has a poor centering limit for the label. Therefore, in this application, the baffle 1 and the rack 2 are designed separately, with a three-dimensional design in terms of structure and using PA+30%GF material, which can effectively solve the strength problems of the two parts of the baffle 1 and the rack 2, and then solve the problem of left-right offset in printing caused by part deformation. In this application, PA+30%GF is a polyamide reinforced glass fiber composite material, which is composed of a polyamide (PA) base material and 30% glass fiber (GF) reinforcing agent; the PA+30%GF material has excellent properties, which is a conventional setting well-known to those skilled in the art here and will not be elaborated further.

[0041] In this embodiment, the first connecting body 3 is connected to the baffle 1, and the second connecting body 4 is arranged opposite to the first connecting body 3 and connected to the rack 2.

[0042] Specifically, in this device, the first connecting body 3, as a support for connecting the rack 2 and the second connecting body 4, is arranged on the baffle 1 and has high stability and strength.

[0043] In one of the embodiments, please refer to Figure 2 , the first connecting body 3 is provided with at least one threaded hole, the second connecting body 4 is provided with a through hole opposite to the threaded hole, the clamping member 5 has a threaded section and a large-diameter section, the threaded section of the clamping member 5 passes through the through hole and is threadedly connected to the threaded hole, and the large-diameter section of the clamping member 5 abuts against the second connecting body 4.

[0044] The first connecting body 3, the second connecting body 4 and the clamping member 5 form a detachable connection through a threaded connection method.

[0045] Furthermore, in this device, the clamping member 5 is a common and easily purchasable screw or bolt in the market. Here, the screw or bolt is a conventional setting well-known to those skilled in the art and will not be elaborated further.

[0046] In one of the embodiments, please refer toFigure 1 、 Figure 2 The first connecting body 3 is further provided with a clamping groove communicating with the threaded hole. A clamping portion 41 is formed on the second connecting body 4 corresponding to the clamping groove. The clamping portion 41 can be cooperatively clamped in the clamping groove, and the communication hole penetrates through the clamping portion 41.

[0047] Through the structure in which the clamping portion 41 and the clamping groove cooperate with each other, the connection strength between the first connecting body 3 and the second connecting body 4 can be enhanced.

[0048] As an implementation manner, the cross-sectional area of the clamping groove is a regular polygon. The cross-section of the clamping portion 41 is arranged to cooperate with the cross-section of the clamping groove, and the clamping portion 41 can slide relative to the clamping groove to limit the relative rotation of the second connecting body 4 and the rack 2 around the axis of the threaded hole with respect to the first connecting body 3.

[0049] The cross-sectional area of the clamping groove being a regular polygon can limit the rotation of the rack 2 relative to the baffle 1 and improve the stability of the device.

[0050] As another implementation manner, the cross-section of the clamping groove is square. The first connecting body 3 is further provided with four guiding grooves. The four guiding grooves are evenly distributed around the clamping groove and are all communicated with the clamping groove. The second connecting body 4 is further formed with four guiding portions 42. The guiding portions 42 are arranged in one-to-one correspondence with the guiding grooves, and the guiding portions 42 can be slidably inserted into the guiding grooves in cooperation.

[0051] The cooperation between the guiding grooves and the guiding portions 42 can not only facilitate installation, but also enhance the limiting effect and improve the stability of the device.

[0052] In one embodiment, please refer to Figure 1 、 Figure 2 The second connecting body 4 further includes a countersunk head groove 7. The countersunk head groove 7 is communicated with the communication hole, and the large-diameter end of the clamping member 5 abuts against the inner wall of the bottom of the countersunk head groove 7.

[0053] The countersunk head groove 7 is used to accommodate the large-diameter section of the clamping member 5, which is not only beautiful but also can enhance the connection stability.

[0054] In one embodiment of the present utility model, there is also provided a baffle module, including a baffle 1, a rack 2 and a connecting device.

[0055] Specifically, the baffle module includes a baffle 1, a rack 2 and a connecting device. Here, reference can be made to the Chinese utility model patent with the application number: CN202123367476.3, titled: A Fixed Paper Shaft of a Label Printer. This is a conventional setting well-known to those skilled in the art and will not be elaborated here.

[0056] Further, the baffle plate 1 and the rack 2 are split into two parts and fastened with screws, enabling both the structures of the baffle plate 1 and the rack 2 to be designed stronger. Moreover, the mold will be simpler, more reliable, and suitable for mass production.

[0057] In this embodiment, as Figure 3 shown, at least one groove 6 is formed on the side of the baffle plate 1 facing away from the first connecting body 3, and the groove 6 is disposed at the connection between the baffle plate 1 and the first connecting body 3.

[0058] Designing multiple grooves 6 on the baffle plate 1 makes the wall thickness of the plastic part uniform, less likely to cause injection molding defects, more stable in size, and less deformed.

[0059] An embodiment of the present utility model further includes a label printer, which includes at least one baffle plate module.

[0060] Generally, a left baffle plate module and a right baffle plate module are provided in the label printer. Here, reference can be made to the Chinese utility model patent with the application number: CN202123367476.3, titled: A Fixed Paper Shaft of a Label Printer. This belongs to the conventional settings well-known to those skilled in the art and will not be elaborated further here.

[0061] For a better understanding of the present utility model, the following Figures 1 to 3 will elaborate on the technical solution of the present utility model in detail:

[0062] The specific working process of the present utility model is as follows: A connecting device is provided between the baffle plate 1 and the rack 2, where the first connecting body 3 is connected to either the baffle plate 1 or the rack 2, the second connecting body 4 is disposed opposite to the first connecting body 3 and is connected to the other of the rack 2 or the baffle plate 1, and at least one clamping member 5 is connected to the second connecting body 4 and can be detachably connected to the first connecting body 3 for detachably connecting the second connecting body 4 and the rack 2 to the first connecting body 3 and the baffle plate 1. Compared with the prior art, separating the baffle plate 1 and the rack 2 and connecting them in a detachable manner not only provides a three-dimensional structure but also effectively solves the strength problems of the two parts of the baffle plate 1 and the rack 2 by using PA + 30% GF material, avoiding deformation of the baffle plate 1 or the rack 2 parts.

[0063] Further, splitting the baffle plate 1 and the rack 2 into two parts and fastening them with screws enables both the structures of the baffle plate 1 and the rack 2 to be designed stronger, and the mold will be simpler, more reliable, and suitable for mass production. Designing a three-dimensional space structure on the rack 2 and the baffle plate 1 can reduce deformation and increase anti-torque. Designing multiple grooves 6 on the baffle plate 1 makes the wall thickness of the plastic part uniform, less likely to cause injection molding defects, more stable in size, and less deformed, effectively controlling the problem of left-right offset during printing.

[0064] With the above structure, the present application can solve the problem in the prior art that due to the injection molding of the baffle 1 and the rack 2 and the structural space limitation, the structural strength of the baffle 1 or the rack 2 is insufficient, resulting in the deformation of the baffle 1 or the rack 2, and then solve the problem of left-right deviation of printing caused by the deformation of parts.

[0065] The specific embodiments of the present utility model described above do not constitute a limitation on the protection scope of the present utility model.
