Description

Technical Field

[0001] This invention relates to the field of equipment external attachment and support structure technology, specifically a magnetic clamp bracket that can be suspended at any angle. Background Technology

[0002] With the widespread use of industrial lighting equipment and various testing instruments, foldable support brackets are typically installed on the back of the equipment to adapt to complex working environments, facilitating the support of the equipment on a workbench or for external use. Existing brackets mostly employ basic friction hinges or spring structures to achieve daily unfolding and folding movements.

[0003] However, existing supports are often functionally limited in practical applications, making it difficult to meet the dual requirements of clamping and large-angle hovering support; they also suffer from unstable support and hovering. The friction damping of traditional pivots is often uneven and has poor load-bearing capacity. When supporting lighting fixtures or instruments with a certain weight, the insufficient damping force at the pivot can easily cause the equipment to collapse or slip under its own weight, making it impossible to maintain stable stepless hovering at the required operating angle, especially making it difficult to achieve large-angle hovering adjustments greater than 90 degrees or even 180 degrees.

[0004] Furthermore, existing stands often lack a reliable physical locking mechanism when folded for storage. In the folded state, the stand usually relies solely on the basic friction of the pivot to maintain a close fit. When the equipment is in a vibrating environment such as an industrial site, machine operation, or vehicle bumps, the stand is prone to loosening, accidentally popping open, and making abnormal noises. This not only affects the carrying experience but also poses a risk of damage due to accidental unfolding. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a magnetic clamp bracket that can hover at any angle. This solves the problems of existing brackets, such as unstable shaft damping when supporting lighting or instruments, resulting in unstable hovering; limited functionality that cannot combine clamping and large-range rotational support; and the lack of a reliable physical locking mechanism in the folded state, which makes them prone to accidental unfolding or shaking.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a magnetic clamp bracket that can hover at any angle, comprising:

[0007] Base body;

[0008] A rotating shaft is connected to the base body;

[0009] The tongue body is pivotally connected to the rotating shaft; the short arm body is pivotally connected to the rotating shaft;

[0010] The long arm body is slidably disposed on the short arm body; and the elastic member has a first end abutting against the base body and a second end abutting against the tongue body.

[0011] The long arm body has a first position close to the rotation axis and a second position away from the rotation axis on the short arm body;

[0012] When the long arm body is in the first position, the end of the long arm body abuts or engages with the tongue body; when the long arm body is in the second position, the long arm body separates from the tongue body.

[0013] Preferably, the long arm body is a one-piece molded structure, or the end of the long arm body away from the rotation axis is rotatably connected to a forearm, and a rotating component is provided between the long arm body and the forearm.

[0014] Preferably, the forearm can rotate and fold at any angle around the rotating member, and the forearm is embedded with a magnet, and the cross-section of the forearm has a triangular structure.

[0015] Preferably, a tongue coupling locking member is provided between the end of the long arm body and the end of the tongue body, the tongue coupling locking member including a protrusion and a recess;

[0016] When the long arm body is in the first position, the protrusion is fitted into the recess.

[0017] Preferably, the base body has a tongue limiting member protruding from its surface. The tongue limiting member is located below the rotation avoidance path of the tongue body, and the bottom surface of the tongue body abuts against the surface of the tongue limiting member.

[0018] Preferably, the surface of the short arm body is provided with a telescopic slide, and the long arm body passes through the telescopic slide;

[0019] A slide rail fixing member is fixedly connected to the outer surface of the short arm body. The slide rail fixing member spans the telescopic slide rail and covers the top of the long arm body.

[0020] Preferably, the surface of the short arm body and the surface of the long arm body are respectively provided with sliding locking members. When the long arm body is in the second position, the sliding locking members on the short arm body and the sliding locking members on the long arm body are in contact with each other.

[0021] Preferably, the elastic element is sleeved on the outer circumferential surface of the rotating shaft.

[0022] Preferably, the end of the short arm body has a short arm sleeve, the end of the tongue body has a tongue sleeve, and the base body has a base sleeve.

[0023] The rotating shaft passes sequentially through the base sleeve, the short arm sleeve, and the tongue sleeve.

[0024] Preferably, a first gasket and a second gasket are sequentially inserted between the end of the rotating shaft and the side wall of the short arm sleeve;

[0025] There is an assembly gap between the end face of the short arm sleeve and the end face of the base sleeve, and the included angle of the assembly gap is less than 2 degrees.

[0026] Preferably, it also includes a device body, wherein the base body is fixedly connected to the outer surface of the device body;

[0027] When the long arm body is in the first position, the bottom surface of the long arm body is attached to the outer surface of the device body under the abutment action of the elastic member.

[0028] This invention provides a magnetic clamp bracket that can hover at any angle. It has the following advantages:

[0029] 1. The bracket achieves the switching between its states through the sliding engagement of the long arm and short arm, combined with the pivotal structure of the tongue body. When the long arm is retracted to the first position, it engages with the tongue body, and under the action of the elastic element, it fits tightly against the device for compact storage. In this state, the structure can also be used directly as a high-strength clamp to hold the device in a pocket or backpack strap. When pulled out to the second position, the two physically separate, and the long arm is completely freed from the downward pressure and transforms into a freely foldable support state. At this time, the long and short arms can achieve a large angle of rotation and hovering greater than 90 degrees or even up to 180 degrees, which allows users to accurately adjust and stabilize the pointing angle of the device using this stepless hovering function.

[0030] 2. In response to frequent pull-out and complex usage conditions, this bracket is designed with a comprehensive protection mechanism: the slide rail fixing component prevents the long arm from tilting up under force during pull-out; the slide-out locking component prevents the long arm from being pulled out excessively and falling off; the tongue coupling locking component with protrusions and indentations prevents accidental disengagement when stored; and the tongue limiting component on the base effectively intercepts the separated tongue body, preventing it from tilting down excessively due to elasticity and causing interference or damage to internal components, thus greatly extending the product's service life.

[0031] 3. Considering the inherent weight of instruments or lighting equipment, this support system is equipped with a base sleeve, a short arm sleeve, and a tongue sleeve in sequence in the rotation axis area, along with a gasket assembly. In particular, a precision assembly gap of less than 2 degrees is reserved between the short arm sleeve and the base sleeve. This gap, in conjunction with the gasket, generates a uniform, stable, and high-strength frictional damping force when the support arm is folded, effectively overcoming the collapse caused by the equipment's own weight and ensuring that the equipment can be stably suspended and supported at any unfolding angle.

[0032] 4. In the stowed state, the downward pressure of the elastic element and the attraction force of the embedded magnet in the long arm work together to firmly attach the bracket to the surface of the equipment body, preventing abnormal noise or separation in the environment of vehicle bumps or machine vibration; at the same time, in the unfolded state, the embedded magnet can also directly attract the entire equipment to the external metal working surface, greatly expanding the fixing methods and applicable scenarios of instruments and lighting equipment.

[0033] 5. The magnetic clamp bracket of the present invention has strong product independence. Its base body can be connected to external equipment by conventional fastening or pasting. Therefore, this bracket can be produced and sold separately as an independent bracket and clamp multi-functional accessory without relying on specific instruments or lighting equipment. Users can install it on various devices that need clamping or support, which greatly expands the commercial application scenarios of the product.

[0034] 6. Dual-axis linkage and triangular configuration significantly improve support stability. In some embodiments of the present invention, by introducing a forearm and a rotating component at the end of the long arm, the support has the dual arbitrary angle adjustment capability of the main axis and the secondary axis. In particular, the forearm is designed as a triangular structure. When the support is in the unfolded state, the user can fold the forearm downward through the rotating component and use the triangular tip or side of the forearm to abut against the working surface. This geometric design of dual-axis adjustment + triangular ground contact effectively prevents the long arm from slipping under force and greatly improves the grip and overall stability of the equipment when it is suspended at a large angle.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Example 1:

[0046] Please see the appendix Figure 1 - Appendix Figure 7 The present invention provides a magnetic clamp bracket that can be suspended at any angle. The magnetic clamp bracket includes a device body 1, a rotating shaft 2, a base body 4, a tongue body 6, a short arm body 7, a long arm body 10, and an elastic element 11.

[0047] The base body 4 is fixedly connected to the outer surface of the device body 1 as a basic support component. It should be noted that the device body 1 in this embodiment is only an example of the support object of this bracket. This bracket is not limited to being fixedly matched with specific equipment. It can be sold and used separately as an independent bracket and clamp accessory. Its base body 4 can be adapted to be installed on the surface of various external objects. The rotating shaft 2 is connected to the base body 4.

[0048] Both the tongue body 6 and the short arm body 7 are pivotally connected to the rotating shaft 2 and can rotate around the rotating shaft 2 so that the user can adjust the support angle.

[0049] The long arm body 10 is slidably mounted on the short arm body 7.

[0050] Specifically, the surface of the short arm body 7 is provided with a telescopic slide 9, and the long arm body 10 passes through the telescopic slide 9;

[0051] A slide rail fixing member 8 is fixedly connected to the outer surface of the short arm body 7. The slide rail fixing member 8 spans the telescopic slide rail 9 and covers the top of the long arm body 10.

[0052] This structure effectively limits the vertical displacement of the long arm body 10 during the sliding process, preventing it from tilting up under force and improving the stability of the pull-out operation.

[0053] The long arm body 10 has a first position close to the rotation axis 2 and a second position far away from the rotation axis 2 on the short arm body 7.

[0054] The surface of the short arm body 7 and the surface of the long arm body 10 are respectively provided with sliding locking members 13. When the long arm body 10 is pulled outward to the second position, the sliding locking members 13 on the short arm body 7 and the sliding locking members 13 on the long arm body 10 are in contact with each other.

[0055] This design provides a reliable anti-detachment limit, preventing the long arm from detaching due to excessive pulling under complex working conditions.

[0056] The elastic element 11 is sleeved on the outer circumferential surface of the rotating shaft 2. The first end of the elastic element 11 abuts against the base body 4, and the second end abuts against the tongue body 6, thereby continuously outputting downward elastic force to the tongue body 6.

[0057] A tongue coupling locking member 15 is provided between the end of the long arm body 10 and the end of the tongue body 6. The tongue coupling locking member 15 includes a protrusion and a recess.

[0058] When the long arm body 10 is in the first position of the retracted state, the end of the long arm body 10 abuts or engages with the tongue body 6. Specifically, the protrusion of the tongue coupling locking member 15 is fitted into the recess, and the stable linkage in the retracted state prevents the bracket from accidentally unfolding when the equipment vibrates.

[0059] At this time, under the action of the transmitted force of the elastic element 11, the bottom surface of the long arm body 10 is tightly attached to the outer surface of the equipment body 1, thereby achieving the effect of reducing the overall thickness of the equipment and compact storage.

[0060] Meanwhile, at least one magnet 14 is embedded in the plate of the long arm body 10. The attraction force of the magnet 14 further enhances the shock resistance during storage, and in the unfolded state, it is also convenient to magnetically hang the instruments and equipment on the external metal working surface.

[0061] When the long arm body 10 slides outward to the second position, the tongue coupling locking member 15 disengages, and the long arm body 10 separates from the tongue body 6.

[0062] At this time, the tongue limiting member 12, which is provided on the surface of the base body 4, comes into play. The tongue limiting member 12 is located below the rotation avoidance path of the tongue body 6.

[0063] After separation, the tongue body 6 is flipped down by elastic force, and its bottom surface is safely abutted against the surface of the tongue limiting member 12.

[0064] The limiting component effectively intercepts the tongue body 6, preventing it from jamming or being damaged due to excessive rotation.

[0065] For the hovering support mechanism, the end of the short arm body 7 has a short arm sleeve 16, the end of the tongue body 6 has a tongue sleeve 17, and the base body 4 has a base sleeve 18.

[0066] The rotating shaft 2 passes through the base sleeve 18, the short arm sleeve 16, and the tongue sleeve 17 in sequence.

[0067] A gasket 3 and a gasket 5 are sequentially inserted between the end of the rotating shaft 2 and the side wall of the short arm sleeve 16.

[0068] There is an assembly gap between the end face of the short arm sleeve 16 and the end face of the base sleeve 18, and the included angle of the assembly gap is less than 2 degrees.

[0069] Through the cooperation of the aforementioned minute assembly gaps and the gasket assembly, a stable and uniform frictional damping force can be generated when the short arm body 7 rotates around the rotating axis 2.

[0070] This damping effect ensures that the instrument can remain stably suspended at any adjustable angle even with a certain weight, effectively preventing gravity-induced collapse and improving its reliability.

[0071] Example 2:

[0072] This embodiment has the same basic structure and working logic as Embodiment 1. The difference is that the end structure of the long arm has been upgraded with dual-axis folding to further improve the stability of the support and the degree of freedom of adjustment.

[0073] Please see the appendix Figure 7 With appendix Figure 6 In this embodiment, the end of the long arm body 10 away from the rotating shaft 2 is not integral, but is rotatably connected to the forearm 20 through the rotating component 19.

[0074] Correspondingly, the magnet 14 for adsorption device and the tongue coupling locking member 15 for engaging with the tongue body 6 are both provided on the forearm 20.

[0075] Meanwhile, the forearm 20 has a triangular cross-section.

[0076] In the folded state, the forearm 20 is flush with the long arm body 10, the tongue coupling locking piece 15 on the forearm 20 engages with the tongue body 6, and the magnet 14 adsorbs the device body 1.

[0077] When the user pulls out the long arm and unlocks it, the entire support arm can not only hover at any angle of 180 degrees around the rotation axis 2;

[0078] Meanwhile, the forearm 20 can also rotate and fold independently around the rotating component 19 at any angle.

[0079] In particular, because the forearm 20 has a triangular cross-section, when the device is in a hover support state, the user can fold the forearm 20 downwards so that the sides or tips of its triangle directly contact the external desktop or ground.

[0080] This dual-axis linkage design, combined with the triangular forearm contact with the ground, creates an extremely stable geometric contact point with the support surface, effectively preventing slippage of a single long rod under extreme stress or on a smooth surface.

[0081] It can not only perfectly adapt to complex support surfaces such as steps and slopes, but also greatly improve the support strength and operating experience when the instrument is hovering at a large angle through the stress stability of the triangular structure.

[0082] Working principle: When the magnetic clamp bracket that can be suspended at any angle is needed, in the natural storage state, the long arm body 10 is located in the first position close to the rotating shaft 2. At this time, the long arm body 10 or the forearm 20 connected to its end and the tongue body 6 are locked together as one by the tongue coupling locking member 15.

[0083] In this state, the device can be used as a highly elastic clip accessory, with the long arm body 10 serving as a clamping arm, making it easy for users to directly clamp it onto pockets, belts, or other load-bearing objects.

[0084] At the same time, the downward pressure of the elastic element 11 is transmitted to the long arm body 10 through the tongue body 6, and with the embedded magnet 14, the bracket is stably attracted and abutted against the surface of the equipment body 1.

[0085] When a user needs to deploy the support, the workflow is as follows:

[0086] First, the user pulls the long arm body 10 outward.

[0087] Under the limiting and guiding influence of the slide rail fixing member 8, the long arm body 10 slides along the telescopic slide rail 9 on the short arm body 7 in a direction away from the rotation axis 2 until it reaches the second position.

[0088] During this pulling process, the long arm body 10 forcibly disengages from the engagement state with the tongue body 6, and the two are physically separated, allowing the long arm body 10 to completely break free from the downward pressure restraint of the elastic element 11.

[0089] Secondly, at the instant the long arm separates from the tongue, the internal mechanism automatically performs two limit protection functions:

[0090] The tongue body 6, which loses the support of the long arm, will fold downward under the pushing force of the elastic member 11, but its bottom surface will immediately abut against the tongue limiting member 12 on the base body 4, thus being safely intercepted and preventing overstepping.

[0091] When the long arm body 10 is pulled to the end, the sliding locking piece 13 on its surface will fit and lock against the sliding locking piece 13 on the surface of the short arm body 7, preventing the long arm body 10 from being pulled out excessively and falling off.

[0092] Then, the untied long arm body 10 and short arm body 7 form a free support arm. The user can fold the support arm upwards to adjust the support angle.

[0093] In particular, after the long arm body 10 separates from the tongue body 6, the support arm is freed from interference avoidance and can rotate freely around the rotation axis 2 to a range of more than 90 degrees or even up to 180 degrees.

[0094] Users can use this large-angle hovering function to finely adjust and stabilize the working pointing angle of the device body 1 under different working conditions.

[0095] When rotating around the rotating shaft 2, friction will be generated between the base sleeve 18, short arm sleeve 16, tongue sleeve 17 that the rotating shaft 2 passes through in sequence, as well as the pads 3 and 5 on both sides.

[0096] The friction between these components and the less than 2-degree assembly gap provide smooth and uniform rotational damping, ensuring that the bracket can be stably suspended at any opening angle.

[0097] In particular, in the embodiment that includes the rotating member 19 and the forearm 20, the support arm can not only be suspended as a whole around the rotation axis 2;

[0098] Users can also fold the forearm 20 downwards independently around the rotating part 19, depending on the actual situation of the desktop or terrain.

[0099] Because the forearm 20 has a triangular cross-section, after folding, the sides or tips of its triangles directly abut against the external working surface.

[0100] This dual-axis linkage and triangular forearm contact geometry can form an extremely stable force point with the support surface, greatly improving the instrument's grip and perfectly overcoming the defect of a single long rod that is prone to slipping under extreme stress or on smooth inclined surfaces.

[0101] Finally, when the user is finished using the device and needs to store it, the user first unfolds the forearm 20 (if any), then folds the entire support arm downwards so that it is flat against the device body 1, and then pushes the long arm body 10 inwards back to the first position.

[0102] The end of the long arm slides back under the tongue body 6, and the tongue coupling locking piece 15 engages again.

[0103] At this point, the elastic force of the elastic element 11 is applied to the entire arm again, and the bracket returns to its initial folded and fitted state, completing a full work cycle.

[0104] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
