Description

Technical Field

[0001] The invention relates to the technical field of stage lighting accessories, in particular to a quick-loading and detaching hook body. Background Art

[0002] In order to enhance the performance effect, various lamps are installed on the existing stage, such as various cutting lamps, beam lamps, wash lamps, strobe lamps, LED strip lamps and laser lamps. Especially for mobile performances, since the stage is temporarily built and needs to be dismantled after the performance, a large number of lamps need to be installed and dismantled, which brings certain difficulties to the stage builders. Most of the existing lamps used for mobile performances are equipped with folding lamp hooks, which saves space and reduces the time used for installation and dismantling.

[0003] Patent CN207035009U discloses an inwardly flippable, disassembly-free folding lamp hook, which is a commonly used folding lamp hook structure in the prior art. Figure 1 The patent is schematically shown in the actual application state. Figure 1 As shown in the figure, in the actual product, taking the clamping of steel pipes with a diameter of 40 to 50 mm as an example, Figure 1 The middle left figure shows that when the opening is at its maximum, the distance A between the movable pressure plate and the screw hinge point is 42 mm. Figure 1 The middle right figure shows that when clamping a 40mm diameter steel pipe, the distance A1 between the movable pressure plate and the screw hinge point is 22mm. It can be concluded that when clamping a 40mm diameter steel pipe, the handle needs to travel a distance of 20mm (42mm-22mm). In this type of lamp hook structure, the commonly used screw thread is M10, and its standard pitch is 1.5mm. In other words, to clamp a 40mm diameter steel pipe, the number of turns the handle needs to be turned is 20 / 1.5>13, that is, more than 13 turns are required. Calculated based on the need to assemble 2 lamp hooks for each lamp, it is necessary to turn the handle more than 26 times to install a lamp on a lighting stand, which is very time-consuming and labor-intensive.

[0004] At the same time, refer to Figure 2 As shown, when this type of lamp hook is actually used and the lamp is hung horizontally, due to the special structure of the movable pressure plate, when the lamp rotates and swings, the movable pressure plate will undergo slight elastic deformation due to the pressure of the handle, which can easily cause the friction force of clamping the steel pipe to fluctuate, and then the lamp can easily rotate slowly around the steel pipe and slide down.

[0005] In addition, refer to Figure 3As shown, due to the limitations of its structural principle, it is difficult to reduce the volume of this kind of lamp hook. Moreover, the number of lamps used at the performance site is increasing currently. As a result, the rotating handle on the lamp hook is prone to interference with the machine feet, so that the hook body may not be able to fold down and cannot be used.

[0006] Patent CN201448780U discloses another lamp hook structure. Referring to Figure 4 As shown, it has a fixed pressing plate and a movable pressing plate arranged in a hinged manner. Although this kind of lamp hook structure can reduce the number of turns when the handle rotates to a certain extent, due to the design limitations of the hook body structure and the structural limitations of the movable pressing plate, it is difficult to further reduce the number of turns of the handle rotation. At the same time, in this solution, if you want to further reduce the number of turns of the handle rotation, it will make it more difficult to turn the handle when screwing, and the user needs to apply a greater force, so it is necessary to increase the size of the handle, resulting in an increase in the volume of the overall lamp hook structure. Summary of the Invention

[0007] Embodiments of the present invention provide a quick-loading and unloading hook body to solve at least one of the technical problems existing in the lamp hook structure in the prior art, such as the long clamping time of the lamp hook, poor clamping reliability when hanging the lamp horizontally, and the large volume of the lamp hook being prone to mutual interference with the machine feet.

[0008] According to one aspect of the present invention, a quick-loading and unloading hook body is provided, including:

[0009] A hook body, on which a fixed pressing plate is provided, and the fixed pressing plate has a first clamping portion;

[0010] A movable pressing plate, hinged at a first hinge point on the hook body, and having a second clamping portion, and the first clamping portion and the second clamping portion form a clamping opening;

[0011] A pushing member, hinged at a second hinge point on the hook body, having a first pushing portion, and the first pushing portion is used to abut against the movable pressing plate to push the movable pressing plate to rotate, so that the second clamping portion approaches the first clamping portion;

[0012] A driving assembly, movably arranged on the hook body, having a second pushing portion, and the second pushing portion is used to abut against the pushing member to push the pushing member to abut against the movable pressing plate, so that the movable pressing plate rotates.

[0013] The quick loading and unloading hook body of the present invention is provided with a pressing member, so as to control the driving assembly to push the pressing member, and the pressing member further pushes the movable pressing plate to rotate, so that the clamping opening is narrowed to clamp the steel pipe. In this design, the rotation of the movable pressing plate depends on pushing the pressing member. By only adjusting the contact position between the first pressing portion on the pressing member and the movable pressing plate, the time taken for the lamp hook to clamp can be adjusted. For example, by adjusting the contact position between the first pressing portion on the pressing member and the movable pressing plate to near the first hinge point, the time taken for the lamp hook to clamp can be significantly reduced. Since the driving assembly abuts against the pressing member through the second pressing portion to drive the rotation of the pressing member, the contact position between the second pressing portion and the pressing member can be adjusted as needed. When it is necessary to further shorten the clamping time, the contact position between the second pressing portion and the pressing member can be adjusted to a position closer to the second hinge point. If it is necessary to make it more labor-saving for the user to operate the driving assembly to clamp, the contact position between the second pressing portion and the pressing member can be adjusted to a position farther from the second hinge point. In addition, when the quick loading and unloading hook body of the present invention clamps, it does not need to rely on the elastic deformation of some structural members, thereby effectively improving the clamping reliability when hanging the lamp horizontally. And because the quick loading and unloading hook body of the present invention can effectively shorten the time taken for clamping, it can effectively reduce the moving stroke of the driving assembly, reduce the volume of the overall hook body, and effectively reduce the occurrence of interference with the machine feet.

[0014] In some embodiments, the position where the first pressing portion abuts against the movable pressing plate is set to be no greater than the distance between the first hinge point and the second hinge point from the first hinge point.

[0015] Thus, by setting like this, the clamping time when the user operates the lamp hook to clamp can be significantly reduced, the number of rotation turns can be reduced, and it is more time-saving and labor-saving.

[0016] In some embodiments, the position where the second pressing portion abuts against the pressing member is set to be no greater than the distance between the first hinge point and the second hinge point from the second hinge point.

[0017] Thus, by setting it in this way, the position where the second pressing part abuts against the pressing member can be set on the side close to the second hinge point, so that the moving stroke when the driving component pushes the pressing member to rotate can be greatly reduced. Moreover, the amplitude of reducing the moving stroke of pushing the pressing member to rotate is calculated multiplicatively with the amplitude of reducing the moving stroke of pushing the movable pressing plate to rotate. Therefore, through the superposition of the two, the moving stroke required by the driving component can be greatly reduced, the time used for clamping can be greatly reduced, and at the same time, the overall volume size of the lamp can be greatly reduced. If the position where the second pressing part abuts against the pressing member is set in the middle of the first hinge point and the second hinge point, it can effectively balance labor saving and time saving, and it is not easy to affect the other structural designs of the lamp, taking into account both practicality and aesthetics. At the same time, this method is also more convenient for processing and assembly.

[0018] In some embodiments, the driving component includes a driving member, the second pressing part is arranged at the first end of the driving member, an external thread is arranged on the driving member, and a threaded connection structure with an internal thread that mates with the external thread on the driving member is arranged on the hook body.

[0019] Thus, by setting it in this way, the movement of the driving member can be controlled by means of threaded connection. Threaded connection has the property of self-locking and high stability, so as to ensure the stability of the overall lamp hook when clamping.

[0020] In some embodiments, the threaded connection structure is set as a nut detachably arranged on the hook body.

[0021] The nut is arranged on the hook body in a manner fixed relative to the hook body.

[0022] Or,

[0023] The nut is arranged on the hook body in a manner rotatable relative to the hook body, and the rotation direction of the nut is set to be able to make the axis of its screw hole deflect towards the first hinge point or towards the second hinge point.

[0024] Thus, by setting it in this way, it is convenient for the maintenance of the structure, and at the same time, the thread sizes of the nut and the driving member can be replaced according to actual needs. At the same time, in some embodiments where the nut is rotatably arranged on the hook body, the contact position between the driving member and the pressing member can also be adjusted by adjusting the orientation of the axis of the screw hole of the nut.

[0025] In some embodiments, a screwing head structure for screwing the driving member to rotate is arranged on the driving member, and a first elastic member is arranged between the screwing head structure and the threaded connection structure.

[0026] Thus, by such an arrangement, it is possible to use the screw head structure to enable the user to more conveniently operate the driving member to rotate, and the first elastic member can be used to prevent loosening of the fit between the driving member and the threaded connection structure, thereby improving the stability during clamping.

[0027] In some embodiments, the threaded connection structure is arranged to be rotatable relative to the hook body on the hook body, and the rotation direction of the threaded connection structure is arranged to be able to deflect its axis towards the first hinge point or towards the second hinge point to rotate, and a second card slot for abutting against the second pressing portion is provided on the pressing member.

[0028] Thus, by such an arrangement, it is possible to cooperate the second card slot with the second pressing portion, thereby increasing the contact area when the pressing member pushes the movable pressing plate, and to a certain extent, ensuring the fixing of the distance between the contact position between the pressing member and the movable pressing plate and the first hinge point, so as to better control the rotation amplitude of the movable pressing plate.

[0029] In some embodiments, an intermediate groove is provided on the hook body, the first hinge point is arranged in the area of the intermediate groove, and the movable pressing plate is arranged in the intermediate groove.

[0030] Thus, by such an arrangement, the movable pressing plate can be arranged in the intermediate groove, and the hook body is used to protect the hinge position on the movable pressing plate and the structure of the movable pressing plate itself.

[0031] In some embodiments, a second elastic member is further provided between the hook body and the movable pressing plate, and the second elastic member is used to drive the movable pressing plate to rotate so that the second clamping portion is away from the first clamping portion.

[0032] Thus, by such an arrangement, the second elastic member can be used to rotate the movable pressing plate, so that the second clamping portion is away from the first clamping portion, and the movable pressing plate is always kept at the maximum amplitude that can be opened, which is beneficial to clamping.

[0033] In some embodiments, a flip connection head and / or a mounting hole are further provided on the hook body,

[0034] The flip connection head includes at least two legs, and a pivot hole is provided on each leg, and the pivot holes on each leg are coaxially arranged, and the plane where the axis of the pivot hole is located is parallel to the plane where the axis of the clamping port is located,

[0035] The plane where the axis of the mounting hole is located is perpendicular to the plane where the axis of the clamping port is located.

[0036] Thus, by such a setting, the lamp can be installed by using the flipping connector or the mounting hole. At the same time, the setting of the axial direction of the pivot hole on the flipping connector and the setting of the axial direction of the mounting port can ensure that when the hook body of the present invention is horizontally hanging the lamp, the driving component and the pressing member further apply force to the movable pressing plate, thereby ensuring the stability when the lamp is horizontally hung.

[0081] The present invention will be further described in detail below with reference to the drawings.

[0082] Figures 5 to 7 Schematically shown is the quick loading and unloading hook body according to an embodiment of the present invention. Referring to Figures 5 to 7 as shown, the quick loading and unloading hook body of the present invention includes a hook body 1, a fixed pressing plate 2 provided on the hook body 1, a movable pressing plate 3 hinged on the hook body 1, a pressing member 5 hinged on the hook body 1, and a driving assembly 4 movably arranged on the hook body 1.

[0083] Specifically, the fixed pressing plate 2 has a first clamping portion 21, and the movable pressing plate 3 has a second clamping portion 31. The first clamping portion 21 and the second clamping portion 31 are arranged opposite to each other to form a clamping opening 13. Among them, the fixed pressing plate 2 is arranged on the hook body 1 and is fixedly connected to the hook body 1 in a detachable or non-detachable manner, so that the fixed pressing plate 2 cannot move relative to the hook body 1 and serves as the fixed end of the formed clamping opening 13. The movable pressing plate 3 is hingedly arranged at the first hinge point 11 of the hook body 1, so that the movable pressing plate 3 can rotate around the first hinge point 11 and serves as the movable end of the formed clamping opening 13. In addition, in some possible implementation manners, an intermediate groove 14 may be further arranged on the hook body 1, the first hinge point 11 is arranged in the area of the intermediate groove 14, and the movable pressing plate 3 is arranged in the intermediate groove 14, so as to protect the structure of the movable pressing plate 3 by using the hook body 1. Exemplarily, referring to Figure 6 and Figure 7 shown, in the implementation manners shown in Figure 6 and Figure 7 the fixed pressing plate 2 is integrally and fixedly arranged on the hook body 1. An intermediate groove 14 is arranged on the hook body 1, and the first hinge point 11 is arranged in the area of the intermediate groove 14, including a first pin fixing hole 111 penetrating through the hook body 1 and a first pin 112 passing through the first pin fixing hole 111. The first pin 112 can be an elastic cylindrical pin, a solid pin or other types of pins that can meet the requirements. The movable pressing plate 3 is arranged in the intermediate groove 14, and the right end of the movable pressing plate 3 is hingedly arranged on the first pin 112 to achieve hinging at the first hinge point 11 on the hook body 1. By arranging the movable pressing plate 3 in the intermediate groove 14, the hinged position of the movable pressing plate 3 can be protected and the structure of the movable pressing plate 3 can be protected. Referring to Figure 6 shown, it can also be further set that only the second clamping portion 31 of the movable pressing plate 3 for clamping is exposed, so as to effectively avoid affecting the rotation work of the movable pressing plate 3.

[0084] For the first clamping portion 21 and the second clamping portion 31, the first clamping portion 21 can be a structure for clamping arranged on the fixed pressing plate 2, such as an arc-shaped clamping surface, etc. Similarly, the second clamping portion 31 can be a structure for clamping arranged on the movable pressing plate 3, such as an arc-shaped clamping surface, etc. Exemplarily, referring to Figure 5 shown, in the implementation manners shown in Figure 5 in order to more conveniently clamp the steel pipe, both the fixed pressing plate 2 and the movable pressing plate 3 are arranged in an arc shape. The first clamping portion 21 on the fixed pressing plate 2 is a side surface located on the inner side of the arc, and the second clamping portion 31 on the movable pressing plate 3 is a side surface located on the inner side of the arc. Among them, referring to Figure 6As shown, the shape of the fixed pressing plate 2 is set to be "V"-shaped, and an arc is formed at its intermediate transition position, so that the first clamping portion 21 has two clamping surfaces, namely the X surface and the Y surface. The second clamping portion 31 provided on the movable pressing plate 3 has one clamping surface, which is the Z surface. The X surface and the Y surface on the fixed pressing plate 2, and the Z surface on the movable pressing plate 3, the three clamping surfaces form a shape similar to a "C", and the surrounded space forms a clamping opening 13. In this embodiment, with the clamping center of the clamping opening 13 as the center, the included angles between the three clamping surfaces are all not greater than 180°, so as to ensure the stability of the clamping opening 13 during clamping. Anti-slip structures for increasing the friction during clamping can be provided on the two clamping surfaces corresponding to the first clamping portion 21 on the fixed pressing plate 2 and the one clamping surface corresponding to the second clamping portion 31 on the movable pressing plate 3. For example, it can be anti-slip patterns, or an anti-slip rubber layer provided on these clamping surfaces, etc., and no more examples are listed here.

[0085] The pushing member 5 is a structure for pushing the movable pressing plate 3 to move. It is hinged at the second hinge point 12 on the hook body 1 and has a first pushing portion 51. The first pushing portion 51 is used to abut against the movable pressing plate 3, so as to push the movable pressing plate 3 to rotate, make the second clamping portion 31 approach the first clamping portion 21, so that the clamping opening 13 shrinks, and further realize clamping of objects such as steel pipes. The first pushing portion 51 on the pushing member 5 is the part used to abut against the movable pressing plate 3. For example, the first pushing portion 51 can refer to the specific structure provided on the pushing member 5, such as a boss provided on the pushing member 5, or it can refer to the partial contact surface on the surface of the pushing member 5 facing the movable pressing plate 3 that will contact the movable pressing plate 3 (that is, there is no special structure designed for the position used to contact the movable pressing plate 3). Exemplarily, referring to Figure 6 As shown, in Figure 6 the embodiment shown, Figure 6 the left end of the pushing member 5 is hinged at the second hinge point 12, and the first pushing portion 51 is provided at the right end of the pushing member 5, that is, at one end of the pushing member 5 far from the second hinge point 12. The second hinge point 12 is provided in the area of the middle groove 14, including the second pin fixing hole 121 penetrating through the hook body 1 and the second pin 122 passing through the second pin fixing hole 121. The second pin 122 can be an elastic cylindrical pin, a solid pin or other types of pins that can meet the requirements, so that the pushing member 5 can also be arranged in the middle groove 14 to protect the structure of the pushing member 5. Referring to Figure 6 and Figure 7As shown, the first pressing part 51 is specifically arranged as an arc-shaped contact surface at one end of the pressing member 5 away from its hinged position. Correspondingly, a first clamping groove 32 for abutting against the first pressing part 51 can be arranged at the position on the movable pressing plate 3 that abuts against the first pressing part 51. The shape of the first clamping groove 32 is also arranged as an arc, and at the same time, the length of the first clamping groove 32 is longer to adapt to the change of the contact position between the first pressing part 51 and the first clamping groove 32 when the movable pressing plate 3 rotates.

[0086] Regarding the position where the first pressing part 51 abuts against the movable pressing plate 3, in some possible implementation manners, this position can be set such that its distance from the first hinge point 11 is not greater than the distance between the first hinge point 11 and the second hinge point 12, that is, it is arranged near the first hinge point 11. With this setting, the stroke required for the first pressing part 51 to move when the pressing member 5 pushes the movable pressing plate 3 to rotate can be greatly reduced, thereby realizing the reduction of the moving stroke of the driving assembly 4 and reducing the overall clamping time. Exemplarily, referring to Figure 6 As shown, in Figure 6 the shown implementation manner, the first pressing part 51 of the pressing member 5 is arranged between the first hinge point 11 and the second hinge point 12, and the position where the first pressing part 51 abuts against the movable pressing plate 3 is near the first hinge point 11, so that the position where the first pressing part 51 abuts against the movable pressing plate 3 is as close as possible to the first hinge point 11, thereby greatly reducing the moving stroke when the pressing member 5 pushes the movable pressing plate 3 to rotate.

[0087] The driving assembly 4 is a driving part for the user to operate and is a structure for pushing the pressing member 5 to move. It is movably arranged on the hook body 1 and has a second pressing part 44. The second pressing part 44 is used to abut against the pressing member 5, thereby pushing the pressing member 5 to rotate, causing the pressing member 5 to push the movable pressing plate 3 to rotate, reducing the clamping port 13, and further realizing the clamping of objects such as steel pipes. The driving assembly 4 can be arranged as a commonly used structure in the art, such as a screw assembly, a push rod assembly, etc. When the driving assembly 4 adopts a screw assembly, the self-locking property of the thread can be utilized for locking. If the driving assembly 4 adopts a push rod assembly, etc., a position for locking the driving assembly 4 needs to be additionally set for locking so that the clamping port 13 remains clamped. Referring to Figure 6 and Figure 7 As shown, in the implementation manner where the driving assembly 4 adopts a screw assembly, the driving assembly 4 includes a driving member 41. The second pressing part 44 is arranged at the first end of the driving member 41, and an external thread is arranged on the driving member 41. A threaded connection structure with an internal thread that cooperates with the external thread on the driving member 41 is arranged on the hook body 1. Furthermore, it cooperates with the driving member 41 through the threaded connection structure, so that the driving member 41 can be controlled to move back and forth along the axis direction of the threaded hole of the threaded connection structure to push the pressing member 5 to move.

[0088] In some possible embodiments, the threaded connection structure may be a nut 42 fixedly arranged on the hook body 1 by means such as welding. The threaded connection structure may also be a threaded hole integrally formed on the hook body 1, which can ensure the structural stability of the threaded connection structure. In some other possible embodiments, the threaded connection structure may be a nut 42 detachably arranged on the hook body 1. Specifically, a nut mounting groove 15 may be provided on the hook body 1. The nut mounting groove 15 may be a through groove penetrating the hook body 1 or may only penetrate to one side of the hook body 1 and communicate with the intermediate groove 14. The nut 42 is detachably mounted on the nut mounting groove 15. Referring to Figures 14 to 20 the embodiment shown, the nut mounting groove 15 may be set as a straight slot, and the shape of the nut 42 may be a square nut 42, so as to be adapted to the shape of the straight slot-shaped nut mounting groove 15, making the nut 42 relatively fixed to the hook body 1 and preventing the nut 42 from moving. Referring to Figures 21 to 27 the embodiment shown, the nut mounting groove 15 may also be set as a circular shape, and the shape of the nut 42 may then be a cylindrical nut 42, so as to be adapted to the shape of the circular nut mounting groove 15. In this setting, the nut 42 can rotate along the axial direction of the nut mounting groove 15, that is, the axis of the threaded hole of the nut 42 can be deflected towards the first hinge point 11 or towards the second hinge point 12 to rotate, so that the position of the second pressing portion 44 of the driving member 41 can be adjusted by rotating the nut 42. Referring to Figures 5 to 13 the embodiment shown, the nut mounting groove 15 may also be set as a special-shaped hole structure combining a circular shape and a straight slot, and thus can be compatible with the installation of a square nut 42 and a cylindrical nut 42. It can be understood that for the nut mounting groove 15 provided on the hook body 1 in the above several embodiments, when manufacturing the hook body 1, it can be directly formed by die-casting mold design. However, due to the high cost of re-opening the mold, for some existing hook body 1 molds, the mold can be modified by modifying the mold, and then the nut mounting groove 15 on the hook body 1 of the present invention can be formed, or the structural style of the nut mounting groove 15 on the hook body 1 can be modified. Referring to Figure 35 and Figure 36 shown, at this time, an opening 16 communicating with the nut mounting groove 15 will be formed at one end of the produced hook body 1 away from the clamping mouth 13.

[0089] In some other possible embodiments, the threaded connection structure may also be a nut fixing bracket 47 mounted on the hook body 1. Referring to Figures 28 to 34In the embodiment shown, the overall cross-section of the nut fixing frame 47 is "U"-shaped, and the two sides of the nut fixing frame 47 are symmetrically arranged. Two fixing holes are provided on each side, which are respectively installed at the first hinge point 11 and the second hinge point 12, so that the nut fixing frame 47 is installed and fixed on the hook body 1, and the nut 42 is arranged on the inner side surface of the middle part of the nut fixing frame 47.

[0090] For the driving member 41, the second pushing portion 44 on the driving member 41 is a portion for contacting with the pushing member 5. For example, the second pushing portion 44 may refer to a structure specifically provided on the driving member 41, such as a boss provided on the driving member 41, or may refer to a portion of the contact surface on the driving member 41 that will contact with the pushing member 5 (i.e., there is no special structure designed for the position for contacting with the pushing member 5). For example, referring to Figure 6 and Figure 7 As shown, in Figure 6 and Figure 7 In the illustrated embodiment, the second pushing portion 44 is specifically configured as an arc-shaped surface at the first end of the driving member 41. Accordingly, in some embodiments, a second draw-in groove (not shown in the accompanying drawings) for abutting against the second pushing portion 44 may also be provided at the position on the pushing member 5 that contacts the second pushing portion 44. The shape of the second draw-in groove may also be configured as an arc, and the length of the second draw-in groove may be longer to adapt to the change in the contact position between the second pushing portion 44 and the second draw-in groove when the movable pressing plate 3 rotates. The shape of the second draw-in groove may also be adapted to the shape of the second pushing portion 44, and then cooperate with the design of the rotatable cylindrical nut 42, so that when the driving member 41 moves toward the pushing member 5, the contact position between the second pushing portion 44 and the pushing member 5 remains unchanged, ensuring that the angle of rotation of the pushing member 5 driven by the unit active stroke remains unchanged.

[0091] For the position of the abutting contact between the second pressing part 44 and the pressing member 5, in some possible embodiments, this position can be set such that its distance from the second hinge point 12 is not greater than the distance between the first hinge point 11 and the second hinge point 12. For example, it can be set near the first hinge point 11, or it can be set in the middle between the first hinge point 11 and the second hinge point 12. If it is set near the first hinge point 11, the stroke required for the second pressing part 44 to move when the operating rod pushes the pressing member 5 to rotate can be significantly reduced. At this time, combined with the reduction in the stroke of the pressing member 5 driving the movable pressing plate 3 to rotate, the reduction rates of the two strokes can be multiplied and superimposed, thereby achieving a significant reduction in the movable stroke of the driving assembly 4 and significantly reducing the overall clamping time. If it is set in the middle between the first hinge point 11 and the second hinge point 12, it can make it more labor-saving to operate the driving member 41 to push the pressing member 5. In this way, since the movable stroke has been optimized by the position of the abutting contact between the first pressing part 51 and the movable pressing plate 3, the optimization rate of further optimizing the movable stroke is poor. Therefore, by optimizing the labor-saving part, the overall structure can effectively balance labor-saving and time-saving, and is not easily affected by other structural designs of the lamp, taking into account both practicality and aesthetics. At the same time, this method is also more convenient for processing and assembly. Exemplarily, referring to Figure 6 as shown in Figure 6 In the embodiment shown, the second pressing part 44 of the driving member 41 is arranged in the middle between the first hinge point 11 and the second hinge point 12, so that it can be more labor-saving to operate the driving member 41, and the overall structure takes into account both labor-saving and time-saving.

[0092] In some possible embodiments, a screwing head structure for screwing the driving member 41 to rotate can also be provided on the driving member 41. The screwing head structure can make it more convenient and labor-saving for the user to rotate the driving member 41. In some other possible embodiments, a first elastic member 43 is arranged between the screwing head structure and the threaded connection structure. The arrangement of the first elastic member 43 can prevent loosening of the cooperation between the driving member 41 and the threaded connection structure, thereby improving the stability during clamping. Exemplarily, referring to Figure 6 and Figure 7 as shown in, in this embodiment, the first elastic member 43 is a spring, and the second pressing part 44 of the driving member 41 sequentially passes through the first elastic member 43 and the threaded connection structure and abuts against the pressing member 5. At the same time, in Figure 6 and Figure 7 In the embodiment shown, the screwing head structure is arranged to pass through the movable handle 45 of the driving member 41 along a direction perpendicular to the axis of the driving member 41, so as to adapt to various narrow operating spaces and facilitate the user to screw the driving member 41. Referring to Figures 14 to 20 the embodiment shown in and Figures 28 to 34The illustrated embodiment shows another possible structure of the wrench head disposed on the driving member 41. The wrench head structure is provided as a fixed handle 46 fixed to the end of the driving member 41 away from the second pressing portion 44.

[0093] In some possible embodiments, the quick-release hook body of the present invention may further be provided with a second elastic member 6 between the hook body 1 and the movable pressing plate 3. The second elastic member 6 is used to drive the movable pressing plate 3 to rotate so that the second clamping portion 31 moves away from the first clamping portion 21, keeping the clamping opening 13 at the maximum angle at which it can be opened. Among them, the second elastic member 6 may be a tension spring or a torsion spring, which are common elastic member structures. The first end of the second elastic member 6 is fixed to the hook body 1, and the second end is fixed to the movable pressing plate 3. Specifically, the movable pressing plate 3 may be provided with a connection structure for connecting with the second elastic member 6, and the hook body 1 may also be provided with a connection structure for connecting with the second elastic member 6. These connection structures may be provided with protrusions to form a structure for hooking the second elastic member 6, or may be provided with depressions to form a structure for hooking the second elastic member 6, or may also be provided with structures such as screws 61 and hooks on their surfaces to form a structure for hooking the second elastic member 6. Correspondingly, the second elastic member 6 may be correspondingly provided with a hanging hole structure for hooking. Exemplarily, referring to Figure 7 shown, in Figure 7 the illustrated embodiment, the second elastic member 6 is provided as a tension spring. Its first end is provided with a circular hole, and its second end is provided with a square hole. A protrusion is provided at one end of the movable pressing plate 3 away from the second clamping portion 31, and an elastic member fixing groove 33 is provided. A screw 61 is threadedly connected to the hook body 1 at a position close to the fixed pressing plate 2. The circular hole of the tension spring is hooked on the screw 61, and the square hole is hooked on the elastic member fixing groove 33, thereby pulling one end of the movable pressing plate 3 away from the second clamping portion 31 closer to the fixed pressing plate 2, causing the movable pressing plate 3 to rotate, moving the second clamping portion 31 away from the first clamping portion 21, and keeping the clamping opening 13 at the maximum angle at which it can be opened.

[0094] In some possible embodiments, the hook body 1 may further be provided with a flipping connector 71 and / or a mounting hole 72 for connecting with a lamp base. When the flipping connector 71 is provided on the hook body 1, the flipping connector 71 includes at least two legs 711, and each leg 711 is provided with a pivot hole 712. The pivot holes 712 on each leg 711 are coaxially arranged, and the plane where the axis of the pivot hole 712 lies is parallel to the plane where the axis of the clamping opening 13 lies. Such an arrangement can ensure that when the hook body 1 of the present invention hangs the lamp horizontally, the driving assembly 4 and the pressing member 5 further apply force to the movable pressing plate 3, thereby ensuring the stability when hanging the lamp horizontally. When the structure provided on the hook body 1 is a mounting hole 72, the mounting hole 72 can be used to mount various detachable flipping connection structures. Specifically, the plane where the axis of the mounting hole 72 lies is perpendicular to the plane where the axis of the clamping opening 13 lies, so as to ensure that when the hook body 1 of the present invention hangs the lamp horizontally, the driving assembly 4 and the pressing member 5 further apply force to the movable pressing plate 3, thereby ensuring the stability when hanging the lamp horizontally. Exemplarily, referring to Figure 5 , Figure 15 , Figure 21 , Figure 28 shown, it shows the structure of a hook body 1 provided with a flipping connector 71. One end of the hook body 1 far from the fixed pressing plate 2 extends, and the flipping connector 71 is arranged on the extended part. The flipping connector 71 includes two legs 711, and each of the two legs 711 is provided with a pivot hole 712. The two pivot holes 712 are coaxially arranged, and the plane where their axes lie is parallel to the plane where the axis of the clamping opening 13 lies. Referring to Figures 8 to 10 , Figure 16 and Figure 17 , Figure 23 and Figure 24 , Figure 30 and Figure 31 shown, Figure 13 shows the structure of a hook body 1 provided with a mounting hole 72. One end of the hook body 1 far from the fixed pressing plate 2 extends, and the mounting hole 72 is arranged on the extended part, and the plane where the axis of the mounting hole 72 lies is perpendicular to the plane where the axis of the clamping opening 13 lies.

[0095] Figures 11 to 13 , Figures 18 to 20 , Figures 25 to 27 , Figures 32 to 34 respectively schematically show the structures of the hook body 1 with different flipping connection structures mounted on the mounting hole 72. Referring to Figure 11 , Figure 18 , Figure 25 and Figure 32As shown, the flipping connection structure includes a first flipping connecting member 73. The first flipping connecting member 73 is a "U" member with a flat bottom surface, symmetric and parallel on both sides, including two connecting edges 731 and an installation bottom surface 732. The two connecting edges 731 are arranged relatively parallel and spaced apart. The two ends of the installation bottom surface 732 are respectively connected to the same-side ends of the two connecting edges 731. One end of the two connecting edges 731 away from the installation bottom surface 732 is semi-circular. First pivot holes 733 are provided on both of the two connecting edges 731, and the first pivot holes 733 are concentric with the semi-circle. A through hole is provided at the center of the installation bottom surface 732. A bolt passes through the through hole, an elastic washer, the mounting hole 72 on the hook body 1 in sequence and is tightly connected with a mounting nut. When a relatively large external force is applied, the first flipping connecting member 73 can rotate around the center of the bolt.

[0096] Referring to Figure 12 , Figure 19 , Figure 26 and Figure 33 As shown, the flipping connection structure includes a second flipping connecting member 74. The second flipping connecting member 74 is an integrally cast member, including two connecting feet 741 and a stud provided above the two connecting feet 741. Second pivot holes 742 are provided on the two connecting feet 741, and the two second pivot holes 742 are coaxial. The stud passes through an elastic washer, the mounting hole 72 on the hook body 1 in sequence and is tightly connected with a mounting nut. In the case of applying a large force, the second flipping connecting member 74 can rotate around the center of the stud.

[0097] Referring to Figure 13 , Figure 20 , Figure 27 and Figure 34 As shown, the flipping connection structure includes a hexagonal bolt 75. The hexagonal bolt 75 passes through from above the mounting hole 72 on the hook body 1, and is sleeved with a flat washer and a spring washer in sequence, and then a mounting nut 76 is screwed on. The mounting nut 76 can be a wing nut or a hexagonal nut.

[0098] The quick-release hook body of the present invention is provided with a pressing member 5, so as to control the driving assembly 4 to push the pressing member 5, and the pressing member 5 further pushes the movable pressing plate 3 to rotate, so that the clamping opening 13 is reduced to clamp the steel pipe. In this design, the rotation of the movable pressing plate 3 depends on pushing the pressing member 5. By only adjusting the contact position between the first pressing portion 51 on the pressing member 5 and the movable pressing plate 3, the time used when the lamp hook is clamped can be adjusted. For example, by adjusting the contact position between the first pressing portion 51 on the pressing member 5 and the movable pressing plate 3 to near the first hinge point 11, the time used when the lamp hook is clamped can be significantly reduced. Since the driving assembly 4 abuts against the pressing member 5 through the second pressing portion 44 to drive the rotation of the pressing member 5, the contact position between the second pressing portion 44 and the pressing member 5 can be adjusted as needed. When it is necessary to further shorten the clamping time, the contact position between the second pressing portion 44 and the pressing member 5 can be adjusted to a position closer to the second hinge point 12. If it is necessary to make it easier for the user to operate the driving assembly 4 to clamp, the contact position between the second pressing portion 44 and the pressing member 5 can be adjusted to a position farther from the second hinge point 12. In addition, when the quick-release hook body of the present invention clamps, it does not need to rely on the elastic deformation of some structural members, so as to effectively improve the reliability of clamping when the lamp is hung horizontally. And because the quick-release hook body of the present invention can effectively shorten the time used for clamping, the moving stroke of the driving assembly 4 can be effectively reduced, the volume of the overall hook body 1 can be reduced, and the occurrence of interference with the machine feet can be effectively reduced.
