DETAILED DESCRIPTION

[0031] In order to better understand and implement, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model.

[0032] In the description of the utility model, it is necessary to explain that the orientation or position relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like is the orientation or position relationship shown based on the drawings, and is only for the convenience of describing the utility model and simplifying the description, and is not intended to indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the utility model belongs. The terms used in the specification of the utility model herein are only for the purpose of describing the specific embodiments and are not intended to limit the utility model.

[0034] Reference Figures 1 to 5The utility model discloses a kind of movie and television lamp supports, including support main body 10, connecting mechanism 20 and locking mechanism 30, support main body 10 has first side 11, connecting mechanism 20 is located first side 11 and is rotatably connected with support main body 10 by pivot 50, specific connecting mechanism 20 includes connecting seat 21 and at least two locking pieces 22, at least two locking pieces 22 are arranged at intervals, connecting seat 21 is connected with one of locking piece 22 that is away from support main body 10, and it is used to connect luminaire;Locking mechanism 30 includes locking seat 32 and top pressure piece 31, locking seat 32 has locking groove, at least one locking piece 321 is arranged in locking groove, at least one locking piece 321 is divided into at least two locking intervals by locking groove, at least two locking pieces 22 are inserted into at least two locking intervals respectively, top pressure piece 31 is used to provide a top pressure and is applied to locking seat 32, locking seat 32 is pressed after at least one locking piece 321 layer layer and is tightly at least two locking pieces 22, to limit the rotational movement of connecting mechanism 20.

[0035] On the basis of above structure, when assembling, pivot 50 can be sequentially passed through connecting seat 21 and at least two locking seat 32 from first side 11 and extend into support main body 10, to rotatably connect connecting seat 21 and at least two locking pieces 22 with support main body 10, so that after luminaire or other movie and television accessories is connected with connecting seat 21, relative rotation movement can be made with support main body 10, to realize the adjustment of angle;

[0036] Then, at least two locking pieces 22 are arranged in at least two locking intervals in locking groove, so that the position of locking piece 22 in locking groove is relatively fixed, each locking piece 22 is limited in specific locking interval, and its moving degree of freedom in horizontal direction is greatly limited, when external force that makes connecting seat 21 and locking piece 22 rotate acts, locking piece 22 is blocked by locking interval side wall, so as to prevent the rotation of locking piece 22, and further limit the rotation of connecting seat 21;

[0037] In addition, since the top pressing piece 31 provides a top pressing force to the outer periphery of the locking seat 32, the locking seat 32 and the locking piece 321 and the locking piece 22 are in contact with each other, and the external force is conducted to the locking piece 321 and the locking piece 22 through the locking seat 32, so that the locking seat 32, the locking piece 321 and the at least two locking pieces 22 are pressed layer by layer, forming a plurality of friction surfaces in contact with each other. Each contact surface will generate a friction force, and the friction forces generated by a plurality of friction surfaces will be superimposed to form a huge resistance. Since the connecting seat 21 is connected to one of the locking pieces 22, the rotation of the connecting seat 21 is limited, so when the lamp or the film and television accessory connected to the connecting seat 21 has a large load and tends to rotate, the friction force to be overcome is very large, thereby further limiting the rotation of the entire connecting mechanism 20, so that the entire structure can still be stable when the load is too large, and is not easy to loosen, thereby reducing the possibility of the lamp or the film and television accessory rotating relative to the support main body 10, effectively avoiding the load on the connecting seat 21 being too large or being subjected to external force.

[0038] Specifically, when the load of the lamp changes, for example, the weight of the lamp increases, causing the connecting mechanism 20 to have a greater tendency to rotate, it is only necessary to increase the top pressing force applied to the top pressing piece 31, so that the top pressing force of the top pressing piece 31 to the outer periphery of the locking seat 32 is increased synchronously. When the external force increases, the locking seat 32 first transmits the increased pressure to the locking piece 321 in contact with it, and the locking piece 321 transmits the pressure to the locking piece 22 in contact with it, and so on. The pressure between each layer increases with the increase of the external force, forming a force superposition effect, so that the pressure between them is more tightly compressed. In this way, the friction force on each friction surface is increased, and these increased friction forces are superimposed to resist the tendency of the lamp to sway due to the increase in weight, so that the entire system can reach a new equilibrium state under the new load condition, thereby maintaining the stability of the lamp and reducing the probability of rotation. The lamp can be firmly locked under different load conditions, so as to be suitable for lamps or other film and television accessories with different loads, and has a wide range of applications.

[0039] It should be noted that the top pressure piece 31 in the embodiment can be a screw or a bolt and nut assembly. During assembly, the screw or bolt is inserted through the locking seat 32, the locking piece 321, the locking piece 22, and extends into the support body 10, and then the nut is sleeved on the outer periphery of the screw or bolt to generate a top pressure by tightening the nut. During the tightening process, pressure is generated along the axial direction of the screw or bolt, and the force is transmitted to the outer periphery of the locking seat 32, thereby achieving the compression of the locking seat 32, the locking piece 321, and the locking piece 22. Of course, a rod-shaped structure (such as a screw or a bolt) can also be inserted through the locking seat 32, the locking piece 321, the locking piece 22, and the support body 10, and nuts or other threaded rotating parts are arranged on both sides of the support body 10. The two rotating parts are sleeved on both ends of the rod-shaped structure, and are tightened to generate a top pressure, which can also achieve the above-mentioned effect.

[0040] In addition, the top pressure piece 31 can also be a clamp, such as a C-shaped clamp composed of a fixed clamp, a movable clamp, and a screw and a nut. In use, the opening of the clamp is aligned with the locking seat 32, the locking piece 321, the locking piece 22, and the support body 10, and then the end of the screw is pressed against the outside of the locking seat 32 or the support body 10. Then rotate the screw, and the movable clamp will gradually approach the fixed clamp to apply uniform pressure to the clamped locking seat 32, locking piece 321, locking piece 22, and support body 10. With the continuous rotation of the screw, the clamping force gradually increases to achieve firm clamping.

[0041] Of course, the top pressure piece 31 can also be a block-shaped component with an inclined surface, such as a wedge. A wedge-shaped hole is provided on the locking seat 32 to connect the wedge. When the wedge is pushed to make the inclined surface of the wedge contact with the locking seat 32 and other components, according to the wedge principle, a component perpendicular to the contact surface will be generated. This component can be used as a top pressure applied to the outer periphery of the locking seat 32. The specific structure of the top pressure piece 31 can be selected according to the actual application scenario.

[0042] In addition, the locking seat 32 in the embodiment can be made of a metal plate or a high-strength plastic plate with a certain thickness, and the locking groove is formed in the locking seat 32 by integral molding. At least one locking piece 321 is arranged in the locking groove by welding or integral molding, so that at least two locking intervals are formed on the locking seat 32 for inserting the locking pieces 22. The locking piece 321 can be made of a metal piece or a plastic piece with high strength and wear resistance. The number of the locking piece 321 can be two, three or more according to the weight of the lamps or the film and television accessories on the connecting seat 21, so that two, three or more locking intervals are formed in the locking groove. At this time, the weight of the locking piece 22 is adjusted to three, four, five or more, so as to be inserted into the plurality of locking intervals respectively, so that the plurality of locking pieces 321 and the plurality of locking pieces 22 form more friction surfaces in contact with each other. After the layers are pressed and fitted, the friction force generated by the plurality of friction surfaces is superimposed on each other to form a greater resistance, which is suitable for lamps or film and television accessories with greater load.

[0043] More specifically, when the connecting seat 21 is assembled, the connecting member 43 such as a plug rod or a clamping block can be arranged on the outer periphery of the connecting seat 21, and a plug hole or a clamping hole is arranged on the locking piece 22 connected thereto at the same time to connect the connecting structure, so that the connecting seat 21 and the locking piece 22 are connected, or the connecting seat 21 and the locking piece 321 are connected by the connecting member 43 such as a bolt or a screw. When the connecting seat 21 is connected to one of the locking pieces 22 through the connecting member 43, the end of the connecting member 43 away from the connecting seat 21 can abut against the other locking piece 22, so that the connecting member 43 increases the contact area between the two locking pieces 22, and the friction force is larger when the two locking pieces 22 are pressed layer by layer, thereby improving the stability of the whole structure.

[0044] In addition, when the locking piece 22 is provided with three or more locking pieces, the connecting seat 21 can be connected to two, three or more locking pieces 22 through the connecting member 43, so that the connecting seat 21 can be more firmly connected to the plurality of locking pieces 22. When the plurality of locking pieces 22 are pressed layer by layer by the locking seat 32 and the locking piece 321, the connecting seat 21 can be more firmly locked by the plurality of locking pieces 22, and is not easy to loosen.

[0045] Further, the support body 10 further has a second side 12 opposite to the first side 11, the locking seat 32 comprises at least three locking pieces 321 which are spaced apart and form at least two locking intervals; the top pressing piece 31 comprises a pressing piece 311 and a connecting rod 312, the at least three locking pieces 321 are respectively provided with a penetrating hole, the connecting rod 312 has a first end 3121 and a second end 3122, the first end 3121 is connected with the pressing piece 311, the second end 3122 is rotated to penetrate in the support body 10 along the first direction and extends to the second side 12, and the pressing piece 311 is used for pressing the at least three locking pieces 321 when the connecting rod 312 rotates.

[0046] Specifically, the locking seat 32 in the embodiment comprises at least three locking pieces 321 which are spaced apart, so that at least two locking intervals are formed on the locking seat 32, when the locking piece 22 is inserted into the locking interval, it is limited by the locking pieces 321 on both sides and cannot move randomly in the horizontal direction. At the same time, due to the pressing effect of the pressing piece 311 on the locking piece 321, the locking piece 22 is also constrained in the vertical direction and is tightly clamped between the two locking pieces 321, which further enhances the stability of the overall structure and prevents the locking piece 22 from loosening, thereby indirectly reducing the probability of loosening of the connecting seat 21 connected with the locking piece 22 and avoiding loosening of the lamp.

[0047] When the connecting rod 312 is rotated, the pressing piece 311 connected with the first end 3121 of the connecting rod 312 will generate a pressure perpendicular to the plane of the locking piece 321. Since there are at least three locking pieces 321 which are spaced apart, the pressure applied by the pressing piece 311 can be uniformly transmitted to each locking piece 321. When each locking piece 321 is subjected to the pressure of the pressing piece 311, it will transmit the force to the adjacent locking piece 321 and the locking piece 22 inserted into the locking interval. Since there is an interval between the locking pieces 321, the pressure will make them extrude each other during the transmission process. The extrusion force makes the contact between the locking piece 321 and the locking piece 22 more closely, thereby enhancing the friction between them and effectively preventing the relative sliding between them, achieving layer-by-layer locking and further reducing the probability of loosening of the connecting seat 21, so that the lamp or the film and television accessory connected with the connecting seat 21 is not easy to shake after being locked, and the structure is more stable.

[0048] It should be noted that the connecting rod 312 in the embodiment can be selected from a threaded rod or a bolt rod structure, at this time, the through hole can be selected as a threaded hole matched with the thread, and a threaded hole matched with the thread is provided on the support body 10 at the same time, so that the connecting rod 312 moves along the axial direction of the connecting rod 312 during rotation to drive the pressing piece 311 to move towards the support body 10, so as to layer by layer press and lock the locking piece 321 and the locking piece 22, and realize the locking effect.

[0049] More specifically, a strip-shaped protrusion is arranged on the end face of the pressing piece 311 close to the locking piece 321, the strip-shaped protrusion surrounds the center of the pressing piece 311 layer by layer from inside to outside, and abuts against the end face of the locking piece 321 when the pressing piece 311 presses the locking piece 321, so as to increase the contact area between the pressing piece 311 and the locking piece 321 through the strip-shaped protrusion, the increase of the contact area increases the actual friction force, which can more effectively prevent the relative sliding between the locking piece 321 and the pressing piece 311, and further makes the whole locking structure more stable and improves the locking effect.

[0050] Of course, a point-shaped pattern, a sawtooth-shaped pattern or a grid pattern and other protruding patterns can also be arranged on the side of the pressing piece 311 close to the locking piece 321, which can also increase the friction force between the pressing piece 311 and the locking piece 321 and realize the above locking effect.

[0051] Further, the holding mechanism 40 is arranged on the second side 12 and connected with the second end 3122 of the connecting rod 312, and the holding mechanism 40 is used to drive the connecting rod 312 to rotate under stress.

[0052] Specifically, the holding mechanism 40 is arranged on the second side 12 and connected with the second end 3122 of the connecting rod 312, at this time, the holding mechanism 40 provides a special force application part for the operator, which is convenient for the operator to grasp and apply force with hands, compared with directly operating the connecting rod 312, the user can more easily apply torque to rotate the connecting rod 312, so as to realize the operation of the pressing piece 311, for example, in the scene where a larger force is required to tighten or loosen, the holding mechanism 40 can make the operation more labor-saving.

[0053] It should be noted that the holding mechanism 40 can be formed by using an existing handle 41, a knob or a combination of a handle and a knob, and the holding mechanism 40 is connected with the second end 3122 by thread connection or clamping connection, so as to apply external force to the connecting rod 312.

[0054] Further, the holding mechanism 40 includes a handle 41, the handle 41 is internally provided with a tooth-shaped groove, the outer periphery of the second end 3122 is provided with a plurality of gear racks 421, and the plurality of gear racks 421 are connected with the tooth-shaped groove in meshing connection.

[0055] Specifically, when the tooth-shaped groove is engaged with the rack 421, multiple teeth simultaneously participate in bearing the force. Compared with the direct contact or simple friction connection mode, the force is not concentrated in one point or one small area, but is uniformly distributed on multiple teeth, and the resistance required to be overcome by each tooth is relatively small, so that the transmission of force is more smooth, the overall operation is more relaxed, and thus the operator can rotate the connecting rod 312 with relatively small force to easily operate the pressing piece 311 and other components, and the use process is more labor-saving.

[0056] In addition, the shapes of the tooth-shaped groove and the rack 421 are matched with each other, and the engagement therebetween is a close mechanical fit. Each tooth can be embedded into the corresponding tooth groove to form a mutual constraint relationship. This constraint relationship limits the relative sliding between the handle 41 and the connecting rod 312, so that during normal use, as long as the teeth are not damaged or excessively worn, stable transmission can be maintained, and slippage phenomenon can be avoided, thereby avoiding the problem of operation failure due to slippage, and improving the stability and reliability of the entire structure.

[0057] Further, the first end 3121 has a larger diameter than the second end 3122, and the first end 3121 is square-shaped. The three locking pieces 321 and the bracket main body 10 are provided with square-shaped holes 322, and the first end 3121 is inserted into the square-shaped holes 322. The second end 3122 is inserted into the tooth-shaped groove after the first end 3121 passes through the square-shaped holes 322.

[0058] Specifically, since the first end 3121 has a larger diameter and is square-shaped, the contact area is larger than that of a circular or small-diameter structure. When bearing a load, the larger contact area can uniformly distribute the force on the contact surface, reduce the unit area pressure, reduce local stress concentration, thereby improving the overall strength and stability of the connection, and making the connecting rod 312 less likely to come out of the hole or become loose.

[0059] Further, the holding mechanism 40 further comprises a connecting ring 42, the connecting rod 312 is inserted into the connecting ring 42, and a plurality of racks 421 are arranged on the outer periphery of the connecting ring 42. The connecting ring 42 is inserted into the handle 41 and is engaged with the tooth-shaped groove.

[0060] Specifically, during assembly, the connecting ring 42 is inserted into the handle 41, and then the connecting rod 312 is inserted into the connecting ring 42, so as to increase the connection points and contact area between the connecting rod 312 and the handle 41 through the connecting ring 42, and make the entire structure more stable.

[0061] In addition, compared with directly penetrating the connecting rod 312 in the handle 41, when the entire structure is under stress, the force can be mainly concentrated in the contact part of the connecting rod 312 and the handle 41, which is easy to cause wear or damage to this part. Therefore, in the embodiment, the connecting ring 42 is used as the connecting bridge between the connecting rod 312 and the handle 41, so as to share the stress between the connecting rod 312 and the handle 41 through the connecting ring 42, reduce the stress concentration of a single component, and when the holding mechanism 40 is subjected to external force, the connecting ring 42 can uniformly distribute the force to the connecting rod 312 and the handle 41, reduce the risk of component damage, and prolong the service life.

[0062] More specifically, the holding mechanism 40 further comprises at least two first gaskets 44, which are arranged between the connecting ring 42 and the support body 10 during assembly. The connecting rod 312 penetrates the support body 10, then penetrates the two first gaskets 44 in sequence and extends into the connecting ring 42. By arranging two first gaskets 44, the gap between the connecting ring 42 and the support body 10 due to manufacturing errors can be filled, so that the cooperation between them is more accurate and accurate, and the stability and reliability of the entire holding mechanism 40 are improved.

[0063] In addition, during the use of the holding mechanism 40, it may be subjected to various external forces and vibrate. At this time, the two first gaskets 44 can play a buffering role, absorb and disperse these vibration energies, reduce the influence of vibration on the connecting ring 42, the support body 10 and the entire holding mechanism 40, and reduce the risk of fatigue wear and loosening of components due to vibration, thereby prolonging the service life of the mechanism.

[0064] It should be noted that the first gasket 44 can be made of metal or plastic material with high strength and good wear resistance.

[0065] Further, the holding mechanism 40 further comprises a connecting piece 43, and the handle 41 is provided with a connecting hole. During assembly, the connecting piece 43 penetrates the connecting hole in sequence and extends into the connecting ring 42, and abuts against the inner wall of the connecting ring 42. The other end of the connecting piece 43 abuts against the outer periphery of the connecting hole, so as to firmly connect the handle 41 and the connecting ring 42 together through the connecting piece 43, so that the relative position between the two is effectively fixed, preventing loosening, displacement or shaking between the handle 41 and the connecting ring 42 during use, ensuring the stability of the overall structure of the holding mechanism 40, thereby improving the accuracy and reliability of operation.

[0066] It should be noted that the connecting piece 43 can be a connecting piece 43 such as a bolt, screw or bolt.
