Description

Technical Field

[0001] This utility model relates to the field of lock processing technology, and in particular to a jig for drilling holes in the lock tongue of an intelligent lock box. Background Technology

[0002] The bolt is the component in a smart lock that directly locks the door. It is the final executor of the entire lock system and the main executor of the anti-theft function. It plays an important role in both security and anti-theft functions. Drilling the bolt is a key step in the lock manufacturing process.

[0003] There is a type of smart lock box with an internal locking tongue, such as Figure 1 As shown, the latch includes a latch body 100, which is irregularly tongue-shaped. The latch body 100 includes an integrally connected oblique tongue portion 101 and a square tongue portion 102. The square tongue portion 102 is provided with a positioning hole 1021, and the oblique tongue portion 101 is provided with a notch groove 1011, thereby dividing the oblique tongue portion 101 into a first oblique tongue portion 1012 and a second oblique tongue portion 1013. During the production process, a first mounting hole 1014 needs to be opened through the first oblique tongue portion 1012, and a non-through second mounting hole 1015 needs to be opened in the second oblique tongue portion 1013. The first mounting hole 1014 and the second mounting hole 1015 are coaxially arranged, and the openings of both the first mounting hole 1014 and the second mounting hole 1015 need to be chamfered.

[0004] Because the latch body 100 is irregularly shaped, when the latch body 100 is placed directly on the workbench for drilling, the latch body 100 is prone to shaking or tilting, which makes the clamping of the latch body 100 unstable and ultimately leads to the problem of the latch body 100 not meeting the drilling requirements.

[0005] Therefore, it is necessary to improve the existing technology. Utility Model Content

[0006] The purpose of this utility model is to solve the problem that when drilling the lock tongue body in the prior art, the lock tongue body is prone to shaking and tilting, which leads to unstable clamping of the lock tongue body by the fixture and ultimately results in the lock tongue body being drilled without meeting the requirements. Therefore, a fixture for drilling the lock tongue in a smart lock box is proposed.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A fixture for drilling a bolt inside a smart lock box includes a positioning plate and a positioning block. The positioning plate and the positioning block cooperate to form a receiving cavity for accommodating the bolt body. A limiting part for limiting the bolt body is provided above the receiving cavity, and a positioning protrusion for positioning the bolt body is provided on the rear side wall of the receiving cavity. The positioning plate includes a first positioning plate and a second positioning plate that are movable and engaged. The positioning block includes a first positioning block fixedly connected to the first positioning plate and a second positioning block fixedly connected to the second positioning plate. When the first positioning plate and the second positioning plate are in a first position, the receiving cavity and the bolt body are in a clearance fit. When the first positioning plate and the second positioning plate are in a second position, the receiving cavity and the bolt body are in a tight fit.

[0009] Furthermore, the second positioning plate is provided with an anti-misalignment post, which is used to prevent the bolt body from being installed in the wrong direction.

[0010] Furthermore, a step is formed between the square tongue and the oblique tongue, and the limiting part abuts against the step to limit the locking tongue body.

[0011] Furthermore, the positioning protrusion is inserted into the positioning hole of the latch body to achieve positioning of the latch body.

[0012] Furthermore, the length of the positioning protrusion is less than the depth of the positioning hole of the latch body.

[0013] Furthermore, a first gap is formed between the first positioning disk and the second positioning disk, and a second gap is formed between the first positioning block and the second positioning block.

[0014] Furthermore, a notch is provided at the lower end of the rear sidewall of the accommodating cavity.

[0015] The beneficial effects of this utility model after adopting the above structure are as follows:

[0016] (1) The present invention provides a clamp for drilling a lock tongue in an intelligent lock box, comprising a positioning plate and a positioning block. The positioning plate and the positioning block cooperate to form a receiving cavity for accommodating the lock tongue body. A limiting part for limiting the lock tongue body is provided above the receiving cavity, and a positioning protrusion for positioning the lock tongue body is provided on the rear side wall of the receiving cavity. The present invention achieves stable and reliable clamping of the lock tongue body to be processed through the cooperation between the positioning block and the positioning plate, thereby achieving precise processing of the lock tongue body. More importantly, after the lock tongue body is placed into the receiving cavity, the first positioning plate and the second positioning plate move to the second position, so that the lock tongue body is in a clamped state throughout the processing, improving the safety of the drilling operation.

[0017] (2) The smart lock box internal bolt drilling fixture of this utility model has an anti-misalignment post on the second positioning plate, which is used to prevent incorrect installation of the bolt body. The design of the anti-misalignment post avoids drilling errors caused by incorrect installation of the bolt body, thus improving the processing qualification rate; at the same time, the design of the anti-misalignment post eliminates the need for operators to carefully distinguish the direction when installing the bolt body, thus improving clamping efficiency.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0028] In the description of this utility model, it should be understood that if terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, the term "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] In this utility model, unless otherwise explicitly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact, or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0032] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this invention are for illustrative purposes only and do not represent the only possible implementation.

[0033] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] like Figures 1 to 6 As shown, a jig for drilling a lock tongue in a smart lock box includes a positioning disk 1 and a positioning block 2. The positioning disk 1 and the positioning block 2 cooperate to form a receiving cavity 3 for accommodating a lock tongue body 100. A limiting part 31 for limiting the lock tongue body 100 is provided above the receiving cavity 3. A positioning protrusion 32 for positioning the lock tongue body 100 is provided on the rear side wall of the receiving cavity 3. The positioning disk 1 includes a first positioning disk 11 and a second positioning disk 12 that are movable and engaged. The positioning block 2 includes a first positioning block 21 fixedly connected to the first positioning disk 11 and a second positioning block 22 fixedly connected to the second positioning disk 12. When the first positioning disk 11 and the second positioning disk 12 are in a first position, the receiving cavity 3 and the lock tongue body 100 are in a clearance fit. When the first positioning disk 11 and the second positioning disk 12 are in a second position, the receiving cavity 3 and the lock tongue body 100 are in a tight fit.

[0035] Based on the above embodiments, the present invention aims to provide a fixture for drilling the latch in a smart lock box, including a positioning disk 1 and a positioning block 2. The positioning disk 1 and the positioning block 2 cooperate to form a receiving cavity 3 for accommodating the latch body 100. A limiting part 31 for limiting the latch body 100 is provided above the receiving cavity 3, and a positioning protrusion 32 for positioning the latch body 100 is provided on the rear side wall of the receiving cavity 3. The present invention achieves stable and reliable clamping of the latch body 100 to be processed through the cooperation between the positioning block 2 and the positioning disk 1, thereby achieving precise processing of the latch body 100. More importantly, after the latch body 100 is placed into the receiving cavity 3, the first positioning disk 11 and the second positioning disk 12 move to a second position, so that the latch body 100 is in a clamped state throughout the processing, improving the safety of the drilling operation. In this embodiment, when the fixture is installed on the drilling machine tool, the first positioning plate 11 and the second positioning plate 12 are respectively connected to hydraulic pressure, and the first positioning plate 11 and the second positioning plate 12 are moved between the first position and the second position by hydraulic pressure.

[0036] In this embodiment, the first position refers to the first positioning plate 11 and the second positioning plate 12 moving away from each other until the receiving cavity 3 and the latch body 100 are in a gap fit, which facilitates the insertion or removal of the latch body 100; the second position refers to the first positioning plate 11 and the second positioning plate 12 moving closer to each other until the receiving cavity 3 and the latch body 100 are in a tight fit, where the latch body 100 is clamped, preventing the latch body 100 from being thrown out during processing and improving processing safety.

[0037] As another preferred embodiment of this utility model, the second positioning plate 12 is provided with an anti-misalignment post 121, which is used to prevent the bolt body 100 from being installed in the wrong direction. In this embodiment, as... Figure 3 As shown, the design of the anti-misalignment post 121 avoids drilling errors caused by incorrect installation of the latch body 100, thus improving the processing qualification rate. At the same time, the design of the anti-misalignment post 121 eliminates the need for operators to carefully distinguish the direction when installing the latch body 100, thereby improving clamping efficiency. If the latch body 100 is installed in the wrong direction during installation, it cannot be installed into the receiving cavity 3.

[0038] As another preferred embodiment of this utility model, a stepped portion 103 is formed between the square tongue portion 102 and the oblique tongue portion 101, and the limiting portion 31 abuts against the stepped portion 103 to limit the locking tongue body 100. In this embodiment, as... Figure 2 and Figure 4As shown, when the latch body 100 is installed into the receiving cavity 3, the limiting part 31 and the step part 103 abut against each other to limit the latch body 100.

[0039] In another preferred embodiment of this utility model, the positioning protrusion 32 is inserted into the positioning hole 1021 of the latch body 100 to position the latch body 100. The length of the positioning protrusion 32 is less than the depth of the positioning hole 1021 of the latch body 100. In this embodiment, as... Figure 2 , Figure 4 and Figure 6 As shown, when the latch body 100 is installed into the receiving cavity 3, the positioning protrusion 32 is inserted into the positioning hole 1021 of the latch body 100 to achieve rapid positioning of the latch body 100. The length of the positioning protrusion 32 is less than the depth of the positioning hole 1021 of the latch body 100. If the positioning protrusion 32 is designed to be too long, it will be inconvenient to insert into the positioning hole 1021, and it will be inconvenient to achieve rapid positioning of the latch body 100.

[0040] In another preferred embodiment of this utility model, a first gap 13 is formed between the first positioning disk 11 and the second positioning disk 12, and a second gap 23 is formed between the first positioning block 21 and the second positioning block 22. In this embodiment, as... Figure 5 As shown, the first gap 13 and the second gap 23 facilitate clamping of the latch body 100 and reduce the precision requirements of the fixture, thereby reducing the processing difficulty of the fixture.

[0041] As another preferred embodiment of this utility model, a notch 33 is provided at the lower end of the rear sidewall of the accommodating cavity 3. In this embodiment, as... Figure 4 and Figure 6 As shown, the notch 33 is designed to prevent the first positioning block 21 from rubbing against or interfering with the second positioning disk 12 when it moves with the first positioning disk 11.

[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
