[0030] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0031] In the description of the present application, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0032] In the description of this application, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed", etc. are understood to exclude the number itself, and "above", "below", "within", etc. are understood to include the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0033] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0034] Time clocks are used to print the time of get off work and leave on cardboard to record the attendance of employees. Compared with electronic attendance devices, time clocks do not need to be equipped with a calculator for processing data, so they are more suitable for low-cost attendance work with small data volumes.

[0035] Generally speaking, a time recorder has a ribbon cassette and prints based on the principle of dot matrix printing. In order to prevent the jammed paper from shaking and shifting after being inserted into the paper insertion slot, a guide groove is usually provided between the ribbon cassette and the paper insertion slot. One end of the guide groove is connected to the paper insertion slot, and the other end faces the print head of the ribbon cassette to ensure that the jammed paper is accurately inserted into place.

[0036] It is understandable that the ribbon cassette of a time recorder needs to be replaced and maintained regularly, so the time recorder will have a preset opening for maintenance, which is usually closed by a cover and opened when needed.

[0037] In the related art, for example in TWM616009U, the cover is usually installed with a buckle. For easy operation, the buckle needs to be engaged with the buckle hole, and the buckle hole also exposes the buckle to the outside. When it needs to be opened, press the buckle in the buckle hole to make the buckle disengage from the buckle hole, thereby unlocking the cover.

[0038] In other related technologies, the time recorder adopts a buckle design similar to that of the battery box, and the buckle also needs to be exposed to the outside for easy operation.

[0039] On the one hand, this is not aesthetically pleasing, and on the other hand, the buckle is often lower than the hole, making it inconvenient for the operator to apply force, resulting in the problem of inconvenient operation.

[0040] Reference Figure 1 and Figure 2 The keyless time clock proposed in the present application includes a main housing 100, which surrounds a cavity with an opening. The opening is used for maintenance. The main housing 100 also includes a first step structure 110, which is arranged at the edge of the opening.

[0041] Further integration Figure 3 The keyless time recorder further includes a cover 200 and a lock assembly 300. The shape of the cover 200 matches the shape of the opening, and the cover 200 can move relative to the main housing 100 to close or open the opening. In the closed state, the first step structure 110 abuts against the cover 200 for positioning.

[0042] The locking assembly 300 includes an operating member 310 and a limiting member 320. The operating member 310 is located on the outer side of the cover body 200, and the limiting member 320 is located on the inner side of the cover body 200. The operating member 310 and the limiting member 320 are connected to each other so that the locking assembly 300 can be movably arranged on the cover body 200. The operating member 310 is actuated to engage or disengage the limiting member 320 with the first step structure 110, thereby locking or releasing the cover body 200.

[0043] On the one hand, the cover body 200 is positioned by the first step structure 110 and locked by the lock assembly 300, so that there is no need to use a key, which makes the keyless time recorder more convenient to use. On the other hand, the operator can indirectly actuate the limit member 320 located on the inside to perform a snap-in or snap-out action through the operating member 310 located on the outside, thereby making the operation more convenient. At the same time, there is no need to set a snap-in hole to expose the limit member 320. The limit member 320 can be snap-fitted with the first step structure 110, thereby simplifying the structural design of the main shell 100. The keyless time recorder can simplify the opening operation of the cover body 200.

[0044] In order to further simplify the opening operation of the cover body 200 , in some embodiments, the operating member 310 may include a protrusion 313 , and the protrusion 313 is higher than the cover body 200 , so that the locking assembly 300 can be actuated by the protrusion 313 .

[0045] It is understandable that the "movability" of the locking assembly 300 can be movement or rotation, as long as it can cause the limiting member 320 to be displaced, thereby engaging with or disengaging from the first step structure 110, and the present application does not impose any limitation on this.

[0046] For example, in some embodiments, the latch assembly 300 can be moved. Figure 3 and Figure 4 In some embodiments, the cover body 200 is provided with a through slot 210 extending in a first direction, the operating member 310 includes a connecting column 311, the connecting column 311 passes through the through slot 210 to connect the limiting member 320, and the locking assembly 300 can move in the first direction to switch between a locked state and a released state.

[0047] The connecting column 311 can be connected to the limit member 320 by fasteners such as screws and pins. It should be pointed out that in order to ensure the installation positioning of the limit member 320, the connecting column 311 and the limit member 320 can be connected to each other through at least two connecting parts to locate the angle of the limit member 320.

[0048] For example, Figure 4 In the illustrated embodiment, both connection posts 311 are provided with screw holes, and the connection posts 311 are connected to the limiting member 320 via screws, and the limiting member 320 is positioned according to the principle of two points determining a straight line.

[0049] In some embodiments, the outer side of the cover body 200 is also recessed with a guide groove 220 extending in the first direction, the through groove 210 is located at the bottom of the guide groove 220, the operating member 310 includes a bottom plate 312, the bottom plate 312 is placed in the guide groove 220, and the connecting column 311 is arranged on the bottom plate 312, and the guide groove 220 is used to limit the travel range of the locking assembly 300.

[0050] The movable range of the locking assembly 300 is limited by the guide groove 220, and the angle of the limiting member 320 is limited by a plurality of connecting parts, thereby preventing the position of the limiting member 320 from deviating from the preset position and ensuring that the limiting member 320 and the first step structure 110 can be accurately engaged or separated.

[0051] It is understandable that, at this time, the protrusion 313 can be set on the bottom plate 312 , and the protrusion 313 is higher than the guide groove 220 , so that the locking assembly 300 can be actuated by the protrusion 313 .

[0052] Back to Figure 2Optionally, in some embodiments, in order to achieve the snap fit with the first step structure 110, the limiter 320 may include a first snap fit portion 321, and the first step structure 110 defines a notch 120. In the released state, the first snap fit portion 321 falls within the range of the notch 120, and in the locked state, the first snap fit portion 321 snaps with the first step structure 110 adjacent to the notch 120.

[0053] More specifically, refer to Figure 2 In some embodiments, in order to facilitate maintenance operations after opening the cover body 200, the opening is open in the second direction (here, the up and down direction) and the third direction (here, the front and back direction). At this time, in order to stably lock the lock assembly 300, the first step structure 110 needs to limit the first locking portion 321 from the second direction and the third direction.

[0054] Specifically, in some embodiments, the first step structure 110 has a first rib 111 and a second rib 112 extending in a first direction (here, the left-right direction). In the locked state, the first snap-fit ​​portion 321 and the cover body 200 clamp the first rib 111 in a third direction to limit the cover body 200 in the third direction, and the second rib 112 and the side wall of the opening clamp the first snap-fit ​​portion 321 in the second direction to limit the cover body 200 in the second direction, so that the cover body 200 is stably locked.

[0055] Of course, in some other embodiments, the first snap-fitting portion 321 and the first step structure 110 can be snapped together or separated without the notch 120, as long as the first snap-fitting portion 321 and the first step structure 110 can be staggered with each other in the released state. The first step structure 110 does not necessarily include the first guard edge 111 and the second guard edge 112, and the present application does not impose any restrictions on this.

[0056] In order to keep the locking assembly 300 in the released state and / or the locked state, in some embodiments, the limit member 320 includes a second snap-fit ​​portion 322, and a second step structure is provided on the inner side of the cover body 300, and the second step structure is located on the moving path of the second snap-fit ​​portion 322. In the released state and / or the locked state, the second snap-fit ​​portion 322 is snap-fitted with the second step structure to position the locking assembly 300.

[0057] For example, two second step structures may be provided on the inner side of the cover body 300, and the two second step structures are arranged at intervals from each other in the first direction, one of the second step structures is engaged with the second buckling portion 322 in the released state, and the other second step structure is engaged with the second buckling portion 322 in the locked state. The two second step structures may be engaged with the same second buckling portion 322, or with different second buckling portions 322, and the present application does not limit this.

[0058] It should be noted that the second step structure can be formed on the cover body 300 in different ways. For example, Figure 2 and Figure 4 In some embodiments, since the thickness of the cover body 200 is relatively thin, in order to provide the guide groove 220 , a boss 230 is convexly provided on the inner side of the cover body 200 , and the guide groove 220 is provided on the boss 230 .

[0059] At this time, the edge of the boss 230 in the first direction may be used as a second step structure.

[0060] Furthermore, since the size of the boss 230 in the first direction is relatively large, the limiting member 320 includes two second buckling portions 322 , which are arranged at intervals in the first direction, and the two second step structures are buckled with different second buckling portions 322 .

[0061] It is understandable that the keyless time recorder further includes a printing component 400 and a guide component 500 . The printing component 400 and the guide component 500 are located inside the cavity. The guide component 500 is used to receive a paper jam 900 , and the printing component is used to print the paper jam 900 .

[0062] In some embodiments, the paper jam 900 is inserted along the second direction. In order to maximize the opening of the main housing 100 and facilitate maintenance, the cover body 200 is provided with a paper insertion slot 240, which extends in the second direction and docks with the guide assembly 500.
