Abstract
Description
Technical Field
[0001] This utility model relates to the field of casing lock technology, and in particular to a casing lock for electronic products. Background Technology
[0002] In recent years, with the popularization of consumer electronics, industrial equipment and IoT terminals, the design of electronic product housing locks has faced multiple technical challenges.
[0003] Electronic product enclosure locks are designed to protect the integrity of the device's enclosure through a physical locking mechanism, preventing unauthorized disassembly or use. Most existing electronic product enclosure locks are electronically integrated mechanical locks or mechanical latch assemblies. Electronically integrated mechanical locks have a built-in electromagnet and sensor; the insertion of a key triggers the electromagnetic engagement pin, requiring both physical key matching and electronic verification to unlock. Mechanical latch assemblies consist of a lock body, lock cylinder, bolt, and drive mechanism. After the key is inserted, rotation drives the lock cylinder gears or levers, controlling the extension and retraction of the bolt to unlock or lock.
[0004] Electronically integrated mechanical locks have the following advantages: 1) High security: Supports multiple authentication methods (fingerprint, password, NFC, facial recognition, etc.), making them more difficult to crack than traditional mechanical locks; some high-end models have anti-technical unlocking (anti-tin foil, anti-pry) and anti-violent damage (anti-electric drill) functions. 2) High convenience: No need to carry keys, supports mobile APP, temporary password, and remote authorization unlocking; suitable for scenarios requiring flexible management such as homes, apartments, and short-term rentals. 3) Intelligent management: Can record unlocking logs and monitor abnormal unlocking behavior in real time (such as multiple erroneous attempts triggering alarms); supports smart home linkage (such as automatically turning on lights when the door is opened, activating the security system). However, they also have the following disadvantages: 1) Power dependence: Requires battery power (usually replaced every 6-12 months), and the lack of power may affect use (but most support USB emergency power supply); 2) Electronic failure risk: Circuit boards, fingerprint modules, etc. may be damaged due to moisture, high temperature, or electromagnetic interference, resulting in high repair costs; 3) Higher price: More expensive than traditional mechanical locks, with high-end models reaching several thousand yuan.
[0005] Mechanical locking assemblies offer the following advantages: 1) High physical security: Made of high-hardness steel (such as 304 stainless steel), they are highly resistant to violent attacks (such as crowbars and electric drills); they have no electronic components and are unaffected by electromagnetic interference or cyberattacks. 2) High stability: Unaffected by power supply, they can still function normally in extreme environments (high temperature, low temperature, humidity); simple structure, low failure rate, and low maintenance costs. 3) Lower price: Cheaper than electronic locks, suitable for users with limited budgets or low demands for smart features. While mechanical locking assemblies are cheaper than electronically integrated mechanical locks, they have more parts, are more complicated to assemble, and are more difficult to repair.
[0006] Therefore, there is an urgent need for a lock for electronic product casings that is simple to use, low in cost, and has good performance. Utility Model Content
[0007] This utility model provides an electronic product casing lock, which solves the technical problems of electronically integrated mechanical locks having a high security factor but high cost and being unsuitable for inexpensive electronic products, and mechanical lock buckle assemblies having too many parts, complicated assembly, and difficult maintenance.
[0008] This utility model provides an electronic product casing lock, which adopts the following technical solution:
[0009] An electronic product housing lock includes a panel, a cover plate, a pin, a screw, and a copper nut. The copper nut is divided into a smooth, threadless section and a threaded engagement section. The copper nut is pre-embedded inside the panel. The cover plate and the panel are connected and fixed by a pin. The screw is screwed into the threaded engagement section of the copper nut through a socket, thereby locking the cover plate.
[0010] By adopting the above technical solution, the copper nut is divided into a smooth, threadless section and a threaded engagement section, which are matched with the copper nut pre-embedded inside the panel. When it is necessary to open the cover plate, the screw only needs to be turned to the threadless position of the copper nut. At this time, the screw and nut are in a threadless engagement state, and the screw is in a free-spinning state, so it will not be unscrewed from the cover plate, thus preventing the screw from falling and being lost.
[0011] The cover plate and the panel are directly connected and fixed by a pin, so that the cover plate and the panel are hinged by the pin. After the screw and the threaded part of the copper nut are screwed together, the cover plate can be fixed on the panel to achieve the locking effect.
[0012] Since locking or unlocking can be achieved simply by hinged connection of the cover plate and panel and threaded connection of screws and nuts, fewer parts are required, assembly is convenient, maintenance is easy, and costs are low, making it highly economical.
[0013] Preferably, the axial length ratio of the unthreaded smooth section (51) and the threaded engagement section (52) is 1:1.
[0014] By adopting the above technical solution, with an axial length ratio of 1:1, after the screw rotates to the point of leaving the thread engagement section of the nut, there is still enough space in the nut to accommodate the screw, making it less likely for the screw to detach from the cover plate after rotating away from the nut, thus better preventing the screw from falling off and being lost.
[0015] Preferably, the screw (12) is divided into a non-spiral section and a spiral section.
[0016] By adopting the above technical solution, the screw is designed with a non-spiral section, which allows the non-spiral section of the screw to rotate and connect with the insertion hole of the cover plate. This ensures that after the screw rotates to a state where it is no longer engaged with the nut, the screw will not come off the cover plate due to rotation, thus better preventing the screw from being unscrewed from the cover plate and lost.
[0017] Preferably, the helical section of the screw (12) and the threaded engagement section (52) of the copper nut (5) are matched.
[0018] By adopting the above technical solution, the screws and nuts can engage well, making the locking of the cover plate and panel more secure.
[0019] Preferably, the pin (13) is knurled.
[0020] By adopting the above technical solution and using a knurled shaft, the pin is less likely to fall off, making the hinge between the cover plate and the panel more stable and of better quality.
[0021] Preferably, the length of the pin (13) is longer than the width of the cover plate (9).
[0022] By adopting the above technical solution, the stability of the pin-hinged cover plate and panel is further improved by making the length of the pin longer than the width of the cover plate.
[0023] Preferably, the nut of the screw (12) is irregularly shaped.
[0024] By adopting the above technical solution, the screw nut is irregularly shaped, requiring the use of a special tool to rotate the screw, thus achieving a better anti-theft effect.
[0025] Preferably, the screw (12) is screwed to the unthreaded smooth section (51) of the copper nut (5), and the screw (12) is in an idle state, located on the cover plate (9).
[0026] By adopting the above technical solution, when the screw and nut are rotated and the cover plate and panel are unlocked, the screw can remain more stably on the cover plate, thus reducing the risk of screw loss.
[0027] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0028] This utility model provides a lock for the casing of an electronic product. A cover plate is directly connected and fixed to the panel via a pin, allowing the cover plate and panel to be hinged together. After being screwed together with a screw and nut, the cover plate is fixed to the panel, achieving a locking effect. Since locking and unlocking are achieved simply by hinged connection of the cover plate to the panel and screw-nut connection, fewer parts are required, assembly is convenient, maintenance is easy, and costs are low, making it highly economical.

[0035] 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.
[0036] Reference Figure 1 An electronic product housing lock includes a panel 1, a cover plate 9, a pin 13, a screw 12, and a copper nut 5.
[0037] One end of the cover plate 9 is hinged to one end of the panel 1 via a pin 13. A through-hole 10 is provided at the end of the cover plate 9 away from the pin 13, perpendicular to the cover plate 9. A nut hole 6 is provided at the end of the panel 1 away from the pin, and a copper nut 5 is fixedly connected within the nut hole 6. The copper nut 5 consists of a smooth, unthreaded section 51 and a threaded engagement section 52. When the cover plate 9 is in contact with the panel 1, the smooth, unthreaded section 51 of the copper nut 5 is close to the cover plate, while the threaded engagement section 52 is away from the cover plate 1. The axial length ratio of the smooth, unthreaded section 51 to the threaded engagement section 52 of the copper nut 5 is 1:1.
[0038] The copper nut is divided into a smooth, threadless section and a threaded engagement section. It is matched with the copper nut embedded in the panel. When the cover needs to be opened, the screw is only turned to the threadless position of the copper nut. At this time, the screw and nut are in a threadless engagement state, and the screw is in a free-spinning state, so it will not be unscrewed from the cover, thus preventing the screw from falling and being lost.
[0039] The cover plate and the panel are directly connected and fixed by a pin, so that the cover plate and the panel are hinged by the pin. After the screw and the threaded part of the copper nut are screwed together, the cover plate can be fixed on the panel to achieve the locking effect.
[0040] A screw 12 is rotatably connected in the pin hole of the cover plate 9. The screw 12 is divided into a non-spiral section and a spiral section. When the cover plate 9 is attached to the panel 1, the spiral section of the screw 12 can be inserted into the copper nut 5. The spiral section of the screw 12 and the threaded engagement section of the copper nut match.
[0041] By setting a screw without a helical section, the screw's non-helical section is rotatably connected to the cover plate's insertion hole. This prevents the screw from detaching from the cover plate after it rotates to a state where it is no longer threaded with the nut, thus better avoiding the phenomenon of the screw being unscrewed from the cover plate and lost.
[0042] refer to Figure 3-4 The nut of screw 12 is located on the side of cover plate 9 away from panel 1. The nut of screw 12 is irregularly shaped. When screw 12 engages with the threaded engagement section 52 of copper nut 5, the nut of screw 12 presses against the surface of cover plate 9 away from panel 1. When screw 12 is turned to the unthreaded smooth section 51 of copper nut 5, screw 12 is in a free-spinning state and is rotatably connected to the pin hole 11 on cover plate 9.
[0043] The pin 13 is knurled and its length is longer than the width of the cover plate 9. The pin 13 passes through the cover plate 9 and the panel 1 in a direction parallel to the surface of the cover plate 9 to achieve a hinge connection.
[0044] The panel 1 has fixing holes 2 at two corners away from the cover plate 9. The cover plate 9 has grooves I 3 and II 4 on the plane away from the panel 1. The panel 1 has a T-shaped groove 7 and an elliptical hole 8 on the side facing the cover plate 9 for complete fit with the cover plate 9.
[0045] The above technical solution provides an electronic product casing lock that solves the technical problems of high security but high cost of integrated electronic mechanical locks, which are not suitable for inexpensive electronic products, and the excessive number of parts in mechanical lock assembly, which makes assembly troublesome and difficult to repair.
[0046] refer to Figure 2 A schematic diagram showing the thread engagement of the screw 12 and the copper nut 5 in the threaded section 52 when the cover plate and the panel are attached.
[0047] A screw 12 is rotatably connected in the pin hole of the cover plate 9. The screw 12 is divided into a non-spiral section and a spiral section. When the cover plate 9 is attached to the panel 1, the spiral section of the screw 12 can be inserted into the copper nut 5. The spiral section of the screw 12 and the threaded engagement section of the copper nut match.
[0048] The nut of screw 12 is located on the side of cover plate 9 away from panel 1. The nut of screw 12 is irregularly shaped. The irregular shape of the nut means that the screw requires a special tool to rotate, thus providing a better anti-theft effect.
[0049] When the screw 12 engages with the threaded section 52 of the copper nut 5, the nut of the screw 12 presses against the surface of the cover plate 9 away from the panel 1. When the screw 12 is turned to the unthreaded smooth section 51 of the copper nut 5, the screw 12 is in a free-spinning state and is rotatably connected to the pin hole 11 on the cover plate 9.
[0050] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
