Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lamps and lanterns, in particular to a lamp fastener. BACKGROUND

[0002] At present, lamps and lanterns are widely used in people's production and life. In order to facilitate the installation of lamps and lanterns, lamp installation supports, lamp fasteners and other related products appear. Different lamps and lanterns have different shapes and structures. The installation methods of lamps and lanterns include: 1. Wall-mounted, installed on the wall for local lighting and decorative lighting; 2. Ceiling-mounted, the lamp is fixed on the surface of the ceiling through the lamp shell or the matched installation support and fastener; 3. Embedded, embedded and fixed in the suspended ceiling; 4. Suspended, the lamp is suspended and fixed on the ceiling by a chain or a suspender.

[0003] However, there is no unified standard for the specific installation structure of lamps and lanterns. Different manufacturers design different installation structures for various lamps and lanterns. For example, some lamps and lanterns need to first fix the matched installation support on the ceiling, and then connect the lamp shell and the installation support through screw assemblies, buckles, sliding rails and other ways. The connection structure between the lamp shell and the installation support is adapted in size, shape, angle and position. The two must be used together. The installation support and the lamp fastener can only be used for specific models of lamps and lanterns and cannot be used for the installation and fixation of other lamps and lanterns, which is not universal. SUMMARY

[0004] An object of the present application is to provide a lamp fastener which can be used to install lamps and lanterns of different shapes and has good universality.

[0005] To achieve the above object, the technical scheme adopted by the present application is as follows: a lamp fastener, comprising an installation support and a fixing piece, the installation support is arranged above the fixing piece, the installation support is provided with an installation part adapted to be detachably connected with a connecting piece, the connecting piece is adapted to be connected with a ceiling, the installation support and at least part of the fixing piece are combined to form an installation channel adapted to pass through a lamp, wherein the fixing piece is made of flexible material.

[0006] Compared with the prior art, the advantages of this application are as follows: Existing lamp fasteners have fixed shapes and can only be adapted to lamps with specific housing structures or specific connection structures, lacking versatility. In contrast, this application uses a rigid mounting bracket and a flexible fastener to form a variable-shape mounting channel. Furthermore, the fastener is made of an elastic material, or it may be inelastic but the length of the part of the fastener involved in the enclosure is adjustable, so that the size of the mounting channel can be changed. In use, the fastener is installed and fixed to the ceiling, and the lamp housing is inserted into the mounting channel to complete the installation and fixation of the lamp. First, there is no need to set a specific connection structure on the lamp housing, which can reduce the cost of processing and manufacturing the lamp housing. Second, the shape and size of the mounting channel are adjustable, which can fix lamps of different sizes and shapes. The fastener has good versatility. Furthermore, the lamp is fixed by inserting it into the mounting channel, that is, by using the fastener to fit the lamp. The connection structure between the lamp and the fastener is simple and easy to operate.

[0007] As a preferred embodiment, the fastener is made of metal, and the length of the part of the fastener that participates in the enclosure is adjustable.

[0008] As a preferred option, the fastener is a strip structure. Firstly, its regular shape facilitates processing; secondly, the strip structure has a certain width, allowing it to wrap around and fit well onto the lamp housing, ensuring uniform and stable force distribution between the fastener and the lamp housing.

[0009] As a preferred option, the fastener is made of flexible stainless steel. It possesses a certain degree of rigidity and can maintain its preset shape when not subjected to external force, facilitating the installation of the light fixture. Furthermore, flexible stainless steel is easily bent, folded, and adjusted, allowing for adjustments to the length of the fastener's enclosing portion to regulate the size of the installation channel.

[0010] As a preferred embodiment, the connector is a bolt assembly and / or a suspension rope, and the mounting portion includes mounting holes suitable for mounting the bolt assembly and / or a suspension portion suitable for mounting the suspension rope. Because it offers both ceiling-mounted and pendant mounting options, it can meet different user installation needs, solving the technical problem of the existing lighting fasteners' overly simplistic installation methods with the ceiling, and achieving the goal of having multiple installation methods for the same product.

[0011] Preferably, the mounting portion has a clearance space suitable for accommodating the end of the connector. This prevents the connector from being exposed in the mounting channel and interfering with the lamp housing, allowing the lamp to be smoothly installed in the mounting channel without the lamp housing being scratched by the connector.

[0012] As a preferred embodiment, the mounting portion includes a top plate, a first side plate extending downward from one end of the top plate, and a second side plate extending downward from the other end of the top plate. The top plate and the first and second side plates on both sides together form the clearance space, which communicates with the mounting channel below. The top plate is provided with the mounting hole, and the first and second side plates are provided with the lifting portion, which is a through hole. The through holes on the first and second side plates are arranged opposite each other to facilitate the passage of the lifting rope. The mounting portion is formed by three plates, with a simple and compact structure that is easy to process and shape. The clearance space communicates with the mounting channel below, allowing for easy installation of bolt components by hand or power tools when the light fixture fastener is ceiling-mounted.

[0013] It is easy to understand that when installing the light fixture fasteners in this application via ceiling mounting, the bolt assembly, including bolts and expansion tubes, should first be inserted into the mounting section. During the bolt insertion process, the bolts are installed from bottom to top, passing through the mounting channel first. However, after the bolts are finally inserted into the ceiling, the lower end of the bolts is within the clearance space and will not affect the subsequent step of inserting the light fixture into the mounting channel. When the light fixture is in the appropriate position relative to the fastener, the locking device can be adjusted from the unlocked state to the locked state to complete the installation. When using the suspended ceiling installation method, the fasteners can be installed on the ceiling first and then the light fixture locking device can be inserted, or the light fixture can be installed relative to the fasteners first and then the fasteners can be suspended from the ceiling. During the entire process of connecting the suspension rope to the mounting section, the suspension rope does not need to pass through the mounting channel below the clearance space.

[0014] Preferably, one end of the fastener is fixedly connected to the mounting bracket, and the middle or other end is connected to the mounting bracket via a locking device. When the locking device switches from the unlocked state to the locked state, the mounting channel tightens to secure the lamp. First, by adjusting the portion of the fastener connected to the locking device, the length of the part of the fastener that participates in enclosing and forming the mounting channel can be changed, thereby adjusting the size of the mounting channel. Second, when the locking device is in the unlocked state, the size of the mounting channel is slightly larger than the outer diameter of the lamp housing, facilitating the entry and exit of the lamp into and out of the mounting channel.

[0015] As a preferred embodiment, the mounting bracket further includes a first connecting plate and a second connecting plate. One end of the mounting portion extends obliquely downward from the first connecting plate, and the mounting bracket is fixedly connected to the fixing member via the first connecting plate. The other end of the mounting portion extends obliquely downward from the second connecting plate, and the second connecting plate is connected to the fixing member via the locking device. The mounting bracket has a simple overall structure and is easy to process and form.

[0016] Preferably, the distance between the first connecting plate and the second connecting plate gradually increases as the direction away from the mounting part moves, so that the width of the mounting channel gradually widens in the horizontal direction. The mounting bracket is integrally formed. The second connecting plate is divided into an upper plate and a lower plate. A portion of the upper plate is bent upward to form a mounting ear. The lower plate is coplanar with the mounting ear. The locking device includes a base plate corresponding to the mounting ear and the lower plate. The inclination of the first connecting plate relative to the horizontal plane is greater than the overall inclination of the upper plate relative to the horizontal plane, but less than the inclination of the lower plate relative to the horizontal plane. The mounting ear is provided with a connecting hole suitable for inserting a bolt assembly. The base plate is detachably connected to the fixing bracket through the connecting hole and the bolt assembly.

[0017] As a preferred embodiment, the locking device is a latch, which includes a faceplate, a base plate, and a buckle. The base plate is mounted on the mounting bracket, the faceplate is rotatably mounted on the base plate, and the buckle is rotatably mounted on the faceplate. The faceplate is connected to the fastener via the buckle. The fastener is bent to form a hook, which hooks onto the buckle to connect the fastener to the buckle. Hooks offer advantages such as quick opening and closing, durability, and reliable locking. The base plate is mounted on the mounting bracket, which has sufficient rigidity to support the base plate. The faceplate is connected to the fastener via the buckle, and the flexible material of the fastener facilitates connection with the buckle. Attached Figure Description

[0026] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application 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. They should not be construed as limiting the specific protection scope of this application.

[0028] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0029] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0030] This application provides a lamp fastener, such as Figures 1 to 7As shown, the lighting fixture fastener includes a mounting bracket 10 and a fixing member 20. The mounting bracket 10 is positioned above the fixing member 20 and has a mounting portion 11 suitable for detachable connection with a connector 30. The connector 30 is suitable for connection with the ceiling. The mounting bracket 10 and at least part of the fixing member 20 together form a mounting channel 2a suitable for the installation of the lighting fixture. The fixing member 20 is made of a flexible material, allowing the mounting channel 2a to be formed into different shapes, such as circles, polygons, or other irregular shapes. This enables lighting fixtures of different shapes to be installed and fastened within the mounting channel 2a, improving the fastener's versatility. Here, "flexible material" means that the fixing member 20 can deform under a small external force, such as manually applied force.

[0031] Existing lamp fasteners have fixed shapes and can only be used with lamps whose housings have specific structures or connection mechanisms, lacking versatility. This application, however, uses a method where the lamp is installed and fixed within the mounting channel 2a. First, the lamp housing does not need a specific connection structure, reducing manufacturing costs. Second, since the mounting channel 2a is formed by the mounting bracket 10 and the fixing member 20, and the fixing member 20 is made of flexible material, the shape of the mounting channel 2a is adjustable, allowing for the fixing of lamps of different shapes. Furthermore, the fixing member 20 can be made of an elastic material, or it can be non-elastic but with an adjustable length of the enclosing portion, allowing for changes in the size of the mounting channel 2a to fix lamps of different sizes. This fastener has excellent versatility; for manufacturers and downstream retailers, different lamps can be installed using the same fastener.

[0032] Furthermore, the luminaire is fixed by passing it through the installation channel 2a, that is, by using fasteners to secure the luminaire. The connection structure between the luminaire and the fasteners is simple and easy to operate, such as... Figure 3 As shown, a long strip of light tube 40 can be installed and fixed to the ceiling by connecting it to the ceiling on the left and right sides respectively through a light fixture fastener.

[0033] In this embodiment, the fastener 20 is made of metal, and the length of the portion of the fastener 20 that participates in the enclosure is adjustable to change the size of the installation channel 2a. It is understood that "fastener 20 is made of metal" here means that the fastener 20 is made of pure metal or an alloy. Compared to elastic materials, metal materials are more durable and less prone to wear and aging. For example, in some embodiments, the fastener 20 may be made of elastic fabric. Elastic fabric can be deformed and stretched to adjust the size and shape of the installation channel 2a, but it has disadvantages such as being easily worn and not durable.

[0034] Preferably, the fastener 20 is made of flexible stainless steel, which has a certain degree of hardness compared to materials such as silicone and cloth. It can maintain its preset shape when not subjected to external human force. Unlike other soft materials, the fastener 20 needs to be manually stretched to form the installation channel 2a, which facilitates the installation of lamps. In addition, flexible stainless steel is easy to bend, fold and adjust, which makes it easy to adjust the length of the part of the fastener 20 that participates in the enclosure to adjust the size of the installation channel 2a.

[0035] Furthermore, the fastener 20 has a strip structure. The fastener 20 has a regular shape and simple structure, which is easy to process. The strip structure has a certain width, which can better wrap around and fit the lamp housing, ensuring that the force between the fastener 20 and the lamp housing is uniform and stable.

[0036] In other embodiments, the fastener 20 may also be an elastic element, or other pure metal or alloy with a certain deformation capability.

[0037] More specifically, the connector 30 is a bolt assembly and / or a lifting rope, and the mounting portion 11 includes a mounting hole 111a suitable for mounting the bolt assembly and / or a lifting portion 112a suitable for mounting the lifting rope. In this embodiment, the mounting portion 11 is provided with both the mounting hole 111a and the lifting portion 112a. Figure 3 As shown, ceiling-mounted installation can be achieved by fixing this fastener to the ceiling using bolt assemblies such as screws and expansion tubes; for example... Figure 4 As shown, the fastener is fixed to the ceiling by connecting it with the hoisting part 112a using a sling rope, which enables hoisting. Since there are two installation methods, different installation needs of users can be met, solving the technical problem that the existing installation methods between the fastener and the ceiling are too limited, and achieving the goal of having multiple installation methods for the same product at the same time.

[0038] As an improvement, the mounting section 11 is provided with a clearance space 1a suitable for accommodating the end of the connector 30. This prevents the connector 30 from being exposed in the mounting channel 2a and interfering with the housing of the lamp, allowing the lamp to be smoothly installed in the mounting channel 2a without the housing of the lamp being scratched by the connector 30, such as the head of the bolt in a bolt assembly.

[0039] like Figure 7 As shown, the mounting part 11 includes a top plate 111, a first side plate 112 extending downward from one end of the top plate 111, and a second side plate 113 extending downward from the other end of the top plate 111. The mounting part 11 is formed by three plates, with a simple and compact structure that is easy to process and form. The top plate 111 and the first side plate 112 and the second side plate 113 on both sides form a clearance space 1a. The clearance space 1a is connected to the mounting channel 2a below. When the fastener of the lamp is installed on the ceiling, the bolt assembly can be installed directly by hand or power tool into the mounting channel 2a, which is convenient for operation.

[0040] The top plate 111 is provided with mounting holes 111a, and the first side plate 112 and the second side plate 113 are provided with lifting parts 112a. The mounting holes 111a are provided on the central top plate 111, so that when the fastener is installed to the ceiling, the top plate 111 can directly abut against the ceiling. The first side plate 112 and the second side plate 113 on both sides are provided with lifting parts 112a. During hoisting, the two spaced-apart lifting parts 112a are connected to the hoisting rope at the same time. There are two force points with a certain distance between the hoisting rope and the mounting bracket 10, which can reduce the shaking after the light fixture and fastener are assembled and installed.

[0041] Furthermore, the hoisting part 112a has a through hole, and the through holes on the first side plate 112 and the second side plate 113 are arranged opposite each other to facilitate the passage of the hoisting rope. The through hole is easy to process and has low manufacturing cost.

[0042] As a supplementary improvement, both the first side plate 112 and the second side plate 113 are perpendicular to the top plate 111. The junction between the top plate 111 and the first side plate 112 is rounded to avoid scratching people or lighting fixtures and to facilitate force transmission. Similarly, the junction between the top plate 111 and the second side plate 113 is also rounded. Furthermore, reinforcing ribs can be provided between the top plate 111 and the first side plate 112 to increase structural stability. Similarly, reinforcing ribs can also be provided between the top plate 111 and the second side plate 113.

[0043] Considering that the bolt assembly head occupies a small volume, the clearance space 1a does not need to be set too deep in the height direction. Therefore, the lengths of the first side plate 112 and the second side plate 113 are relatively short, while the length of the top plate 111 is relatively long. This is to enable the mounting bracket 10 to quickly unfold in the horizontal direction to form an installation channel 2a with a certain width, and to make the interval between the two lifting parts 112a larger, so that after the lamp and lamp fasteners are assembled, the center of gravity of the assembly falls between the two lifting parts 112a.

[0044] This embodiment further provides dimensional parameters. The length of the top plate 111 is set between 20mm and 30mm, specifically 20mm, 25mm, 30mm, etc. The width of the top plate 111 is set between 10mm and 20mm, specifically 10mm, 15mm, 20mm, etc. Correspondingly, the mounting hole 111a is set as an oblong hole. The top plate 111 can be made of stainless steel with high hardness. More specifically, the mounting bracket 10 can be formed by bending a stainless steel plate with a thickness between 1mm and 3mm. It can be clearly seen from the attached drawings that the thickness and width of each part of the mounting bracket 10 are basically the same. The thickness of the flexible material fastener 20 is significantly less than the thickness of the mounting bracket 10, while the width of the fastener 20 is the same as the width of the mounting bracket 10, so as to maintain the regularity of the shape of the entire lamp fastener.

[0045] Preferably, one end of the fastener 20 is fixedly connected to the mounting bracket 10, and the middle or other end is connected to the mounting bracket 10 via a locking device 50. By adjusting the part of the fastener 20 connected to the locking device 50, the length of the part of the fastener 20 that participates in enclosing and forming the mounting channel 2a can be changed, thereby adjusting the size of the mounting channel 2a. When the locking device 50 switches from the unlocked state to the locked state, the mounting channel 2a tightens to fix the lamp. That is, when the locking device 50 is in the unlocked state, there is at least a certain amount of space between the two connecting parts connected by the locking device 50 at the end of the mounting bracket 10 and the middle or end of the fastener 20, so that the size of the mounting channel 2a is slightly larger than the outer diameter of the lamp housing, making it easy for the lamp to enter and exit the mounting channel 2a. When the locking device 50 is in the locked state, the two connecting parts connected by the locking device 50 are limited, the mounting channel 2a tightens and becomes smaller, clamping the lamp to achieve fixation. When using this fastener to install the lamp to the ceiling at a high place, there is no need to perform welding, drilling or other operations, which is convenient for operation.

[0046] The mounting bracket 10 also includes a first connecting plate 12 and a second connecting plate 13. One end of the mounting part 11 extends obliquely downward from the first connecting plate 12. The mounting bracket 10 is fixedly connected to the fixing member 20 through the first connecting plate 12. The other end of the mounting part 11 extends obliquely downward from the second connecting plate 13. The second connecting plate 13 is connected to the fixing member 20 through the locking device 50. The overall structure of the mounting bracket 10 is simple and easy to process and form. As the direction moves away from the mounting part 11, the distance between the first connecting plate 12 and the second connecting plate 13 gradually increases, so that the width of the mounting channel 2a gradually widens in the horizontal direction.

[0047] When installing the ceiling-mounted light fixture fastener of this application, the bolt assembly, including the bolt and expansion tube, should first be inserted into the mounting part 11. During the bolt insertion process, the bolt is installed from bottom to top, passing through the mounting channel 2a first. However, after the bolt is finally inserted into the ceiling, the lower end of the bolt is within the clearance space 1a, which will not affect the subsequent step of inserting the light fixture into the mounting channel 2a. When the light fixture is in the appropriate position relative to the fastener, the locking device 50 is released from... Figure 6 The installation is complete once the unlocked state is adjusted to the locked state. When using ceiling installation, the fasteners can be installed on the ceiling first and then the light fixture locking device 50 can be inserted, or the light fixture can be installed relative to the fasteners first and then the fasteners can be hoisted onto the ceiling. During the entire process of connecting the hoisting rope to the hoisting part 112a, the hoisting rope does not need to pass through the installation channel 2a below the clearance space 1a.

[0048] In some embodiments, the first connecting plate 12 is welded to the fastener 20, which means that the fastener 20 is a weldable metal material, such as strip-shaped flexible stainless steel. The end of the fastener 20 covers at least half the length of the first connecting plate 12. By increasing the welding area, the stability of the welded structure is ensured, and cracking or even detachment at the connection between the fastener 20 and the first connecting plate 12 is avoided, thereby improving the durability of the lamp fastener.

[0049] In some embodiments, the mounting bracket 10 is integrally formed, that is, the first connecting plate 12, the second connecting plate 13, and the mounting part 11 are an integral structure. The integrally formed structure has good strength. The mounting bracket 10 can be cast or bent from a single sheet of material. The fastener 20 is also integrally formed, reducing unnecessary assembly steps and lowering the processing and manufacturing costs.

[0050] In some embodiments, the locking device 50 is a latch, which has the advantages of quick opening and closing, durability, and reliable locking. The latch includes a panel 51, a base plate 52, and a buckle 53. The base plate 52 is mounted on the mounting bracket 10, the panel 51 is rotatably mounted on the base plate 52, and the buckle 53 is rotatably mounted on the panel 51. The panel 51 is connected to the fastener 20 through the buckle 53. Considering that the fastener 20 is made of a flexible material, the base plate 52 is mounted on the mounting bracket 10. The mounting bracket 10 has a large rigidity to support the base plate 52, and the panel 51 is connected to the fastener 20 through the buckle 53. The flexible material of the fastener 20 makes it easier to establish a connection with the buckle 53.

[0051] like Figure 6 As shown, the fastener 20 is bent to form a hook 21. The right end of the fastener 20 is bent downwards, and this bent-down part does not participate in the enclosure with the mounting bracket 10. The middle part of the fastener 20 is enclosed with the mounting bracket 10. The fastener 20 is connected to the buckle 53 by hooking the hook 21 onto the buckle 53. It can be understood that when the fastener 20 is made of metal material, such as flexible stainless steel, since the fastener 20 itself has a certain degree of hardness, one end of the fastener 20 can be bent to form a hook 21. The hook 21 is hooked onto the buckle 53 to achieve the connection between the middle part of the fastener 20 and the buckle 53. The operation is convenient. The user can bend the flexible stainless steel or other metal material from any node in the middle or end as needed, thereby adjusting the length of the part of the fastener 20 that participates in the enclosure with the mounting bracket 10 to form installation channels 2a of different sizes.

[0052] In other embodiments, when the fastener 20 is made of a softer material such as fabric or rubber, the end of the fastener 20 can be connected to the buckle 53 by means of perforation, sewing, etc.

[0053] In this embodiment, because the buckle is relatively long, to avoid the fastener protruding too much outward from the side with the buckle relative to the other side after the buckle is installed, the second connecting plate 13 is not symmetrically arranged with the first connecting plate 12, but has been improved. Specifically, the second connecting plate 13 is divided into an upper plate 131 and a lower plate 132. A portion of the upper plate 131 is bent upward to form a mounting ear 1311. The lower plate 132 is coplanar with the mounting ear 1311. This also means that the overall inclination of the upper plate 131 relative to the horizontal plane is less than the inclination of the lower plate 132 relative to the horizontal plane. The locking device 50 includes a base plate 52 corresponding to the mounting ear 1311 and the lower plate 132. The inclination of the first connecting plate 12 relative to the horizontal plane is greater than the overall inclination of the upper plate 131 relative to the horizontal plane, but less than the inclination of the lower plate 132 relative to the horizontal plane. The effect of this structure of the second connecting plate 13 is as follows: Figure 6 As shown, the dashed line indicates a symmetrical mirror image of the left half of the fastener 20 with respect to the mounting portion 11. Viewed from the direction shown, after the locking device 50 is installed on the right half of the fastener, the protruding portion is smaller compared to the left half. Looking at the upper half of the mounting channel 2a, the width of the right half is slightly greater than the left half. However, looking at the lower half of the mounting channel 2a, the two sides of the mounting channel 2a are basically symmetrical. Since the housing of a lamp is generally symmetrical, ... Figure 6 As shown, the luminaire can be centered within the installation channel 2a, thus the overall structure of the installation channel 2a is quite reasonable.

[0054] In some embodiments, the mounting ear 1311 is provided with a connection hole 131a suitable for inserting a bolt assembly. The base plate 52 is detachably connected to the fixing bracket through the connection hole 131a and the bolt assembly. In the prior art, the base plate 52 of the buckle is generally provided with a fixed hole for connection with the corresponding mounting part 11 through the bolt assembly. However, in this application, by providing a corresponding connection hole 131a on the mounting ear 1311, the base plate 52 can be connected to the mounting ear 1311 with the bolt assembly. Furthermore, since the mounting ear 1311 is raised relative to the upper plate 131, the portion of the bolt assembly below the connection hole 131a can be prevented from occupying the space in the wearing channel, thus preventing the bolt assembly here from squeezing the lamp housing installed in the mounting channel 2a.

[0055] In other embodiments, the base plate 52 of the latch is directly welded to the mounting ear 1311 and / or the lower plate 132, that is, the latch is fixedly mounted and non-removable relative to the mounting bracket 10.

[0056] Furthermore, the mounting ear 1311 is a rectangular plate, with a simple structure and easy processing. It can be made by selecting a rectangular area on the upper plate 131 as the mounting ear 1311, cutting off the side away from the lower plate 132 and its two adjacent sides, and then bending it upwards with the side closest to the lower plate 132 as the pivot axis until it is coplanar with the lower plate 132. Furthermore, the raised end of the mounting ear 1311 is machined with rounded corners to prevent the mounting ear 1311 from accidentally scratching people's hands.

[0057] It is easy to understand that when the latch is in the locked state, the panel 51 and the base plate 52 are fastened together, and the protrusion 521 on the base plate 52 is inserted into the corresponding lock hole 51a on the panel 51, such as...
