Description

Technical Field

[0001] This utility model relates to the field of stage lighting accessories technology, and in particular to a quick-loading and unloading hook. Background Technology

[0002] To enhance the performance effect, existing stages are equipped with a variety of lighting fixtures, such as various cutting lights, beam lights, color-changing lights, strobe lights, LED strip lights, and laser lights. Especially for mobile performances, where stages are temporary structures that need to be dismantled after the performance, a large number of lighting fixtures need to be installed and dismantled, posing a challenge to stage setup personnel. Most existing lighting fixtures used for mobile performances are equipped with folding hooks, achieving the effect of saving space and reducing the time spent on installation and dismantling.

[0003] Patent CN207035009U discloses an inward-flipping, non-disassembly folding lamp hook, which is a common folding lamp hook structure in the prior art. Figure 1 This illustration schematically demonstrates the practical application of the patented technology. (Refer to...) Figure 1 As shown, in its actual products, taking a steel pipe with a diameter of 40-50mm as an example, Figure 1 The left-middle figure shows that when the opening is at its maximum, the distance A between the movable pressure plate and the screw hinge point is 42mm. Figure 1 The diagram on the right shows that when clamping a 40mm diameter steel pipe, the distance A1 between the movable pressure plate and the screw hinge point is 22mm. Therefore, the handle needs to travel 20mm (42mm - 22mm) to clamp a 40mm diameter steel pipe. In this type of lamp hook structure, the commonly used screw thread is M10, with a standard pitch of 1.5mm. This means that to clamp a 40mm diameter steel pipe, the handle needs to be turned more than 13 times (20 / 1.5 > 13). Assuming each lamp requires two lamp hooks, installing one lamp on the lamp holder would require turning the handle more than 26 times, which is extremely time-consuming and labor-intensive.

[0004] At the same time, refer to Figure 2 As shown, when this type of lamp hook is used in actual use, when 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. This can easily cause the friction force of clamping the steel pipe to fluctuate, which can easily lead to the lamp slowly rotating and slipping off the steel pipe.

[0005] Additionally, refer to Figure 3As shown, due to the limitations of its structural principle, this type of lamp hook is difficult to reduce in size. Meanwhile, the number of lights used in performance venues is increasing, which makes it easy for the rotating handle on the lamp hook to interfere with the machine feet, potentially causing the hook body to be unable to fold down and become unusable.

[0006] Patent CN201448780U discloses another lamp hook structure, see reference Figure 4 As shown, it has a fixed pressure plate and a hinged movable pressure plate. Although this lamp hook structure can reduce the number of turns of the handle to some extent, it is difficult to further reduce the number of turns due to the design limitations of the hook body and the structural limitations of the movable pressure plate. At the same time, if you want to further reduce the number of turns of the handle in this solution, it will make the handle more difficult to turn, requiring the user to apply more force, thus requiring a larger handle size and increasing the overall size of the lamp hook structure. Utility Model Content

[0007] This utility model provides a quick-loading and unloading hook body to solve at least one of the technical problems existing in the prior art, such as excessively long clamping time, poor clamping reliability when hanging lamps horizontally, and excessively large size of the lamp hook that easily interferes with the machine feet.

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

[0009] The hook body is provided with a fixing plate, and the fixing plate has a first clamping part;

[0010] The movable pressure plate is hinged to the first hinge point on the hook body and has a second clamping part, the first clamping part and the second clamping part forming a clamping opening;

[0011] The pushing member, hinged to the hook body at the second hinge point, has a first pushing part, which is used to abut against the movable pressure plate to push the movable pressure plate to rotate, so that the second clamping part moves closer to the first clamping part;

[0012] The drive assembly is movably mounted on the hook body and has a second pushing part. The second pushing part is used to abut against the pushing member to push the pushing member against the movable pressure plate, causing the movable pressure plate to rotate.

[0013] This utility model's quick-loading hook body is equipped with a pushing component. A control drive assembly pushes the pushing component, which in turn pushes a movable pressure plate to rotate, thus narrowing the clamping opening and clamping the steel pipe. In this design, the rotation of the movable pressure plate relies on pushing the pushing component. Adjusting the contact position between the first pushing part on the pushing component and the movable pressure plate allows for adjustment of the clamping time. For example, adjusting the contact position between the first pushing part and the movable pressure plate to near the first hinge point significantly reduces the clamping time. Since the drive assembly drives the pushing component's rotation by abutting against the second pushing part, the contact position between the second pushing part and the pushing component can be adjusted as needed. When further shortening the clamping time is required, the contact position can be adjusted closer to the second hinge point. Conversely, if it is necessary for the user to operate the drive assembly more effortlessly during clamping, the contact position can be adjusted further away from the second hinge point. Furthermore, the quick-release hook of this invention does not rely on the elastic deformation of certain structural components for clamping, thus effectively improving the reliability of clamping when hanging lamps horizontally. Moreover, because the quick-release hook of this invention effectively shortens the clamping time, it can effectively reduce the travel of the drive assembly, thereby reducing the overall size of the hook and effectively minimizing interference with the machine feet.

[0014] In some embodiments, the position where the first pushing part abuts against the movable pressure plate is set such that the distance between it and the first hinge point is not greater than the distance between the first hinge point and the second hinge point.

[0015] Therefore, this setting can significantly reduce the clamping time for users when operating the lamp hook clamp, reduce the number of rotations, and save more time and effort.

[0016] In some embodiments, the position where the second pressing part abuts against the pressing member is configured such that the distance between the second pressing part and the second hinge point is not greater than the distance between the first hinge point and the second hinge point.

[0017] Therefore, by setting the position where the second pressing part abuts against the pressing member closer to the second hinge point, the travel distance of the drive assembly when rotating the pressing member can be significantly reduced. Furthermore, the reduction in the travel distance of the pushing member is multiplied by the reduction in the travel distance of the movable pressure plate, resulting in a substantial reduction in the required travel distance of the drive assembly, significantly reducing clamping time, and drastically reducing the overall size of the lamp. Alternatively, placing the position where the second pressing part abuts against the pressing member at the midpoint between the first and second hinge points effectively balances labor and time savings, minimizing impact on other structural designs of the lamp, thus combining practicality and aesthetics. This approach also makes manufacturing and assembly more convenient.

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

[0019] Therefore, by setting it up in this way, the movement of the drive component can be controlled by a threaded connection. The threaded connection has a self-locking property and high stability, thus ensuring the stability of the entire lamp hook when clamped.

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

[0021] The nut is configured to be fixed to the hook body in a manner that is relative to the hook body.

[0022] or,

[0023] The nut is configured to be rotatably mounted on the hook body relative to the hook body, and the rotation direction of the nut is configured to allow the axis of its screw hole to rotate toward either the first hinge point or the second hinge point.

[0024] Therefore, this design facilitates structural maintenance and allows for the replacement of the thread size of the nut and drive component as needed. Furthermore, in some embodiments where the nut is rotatably mounted on the hook body, the contact position between the drive component and the pushing component can be adjusted by changing the orientation of the nut's threaded hole axis.

[0025] In some embodiments, the driving member is provided with a screw head structure for turning the driving member, and a first elastic element is provided between the screw head structure and the threaded connection structure.

[0026] Therefore, this configuration allows the user to more easily operate the drive component to rotate using the screw head structure, and the first elastic element can be used to prevent loosening of the fit between the drive component and the threaded connection structure, thereby improving stability during clamping.

[0027] In some embodiments, the threaded connection structure is configured to be rotatably mounted on the hook body relative to the hook body, and the rotation direction of the threaded connection structure is configured to allow its axis to rotate toward the first hinge point or toward the second hinge point. The pusher is provided with a second slot for abutting against the second pusher portion.

[0028] Therefore, by using this configuration, the second slot can cooperate with the second pressing part, thereby increasing the contact area when the pressing part pushes the movable pressure plate, and to a certain extent ensuring the fixation of the distance between the contact position between the pressing part and the movable pressure plate and the first hinge point, so as to better control the rotation amplitude of the movable pressure plate.

[0029] In some embodiments, the hook body is provided with a central groove, the first hinge point is located within the area of ​​the central groove, and the movable pressure plate is located within the central groove.

[0030] Therefore, by setting it up in this way, the movable pressure plate can be placed in the middle groove, and the hook body can be used to protect the hinge position on the movable pressure plate and the structure of the movable pressure plate itself.

[0031] In some embodiments, a second elastic element is further provided between the hook and the movable pressure plate. The second elastic element is used to drive the movable pressure plate to rotate so that the second clamping part moves away from the first clamping part.

[0032] Therefore, by using this configuration, the movable pressure plate can be rotated by the second elastic element, causing the second clamping part to move away from the first clamping part, so that the movable pressure plate is always kept at the maximum range of opening, which is beneficial for clamping.

[0033] In some embodiments, the hook body is further provided with a flip connector and / or mounting holes.

[0034] The flip connector includes at least two legs, each leg having a pivot hole. The pivot holes on each leg are coaxially aligned, and the plane containing the axis of the pivot hole is parallel to the plane containing the axis of the clamping opening.

[0035] The plane containing the axis of the mounting hole is perpendicular to the plane containing the axis of the clamping opening.

[0036] Therefore, with this configuration, the lamp can be installed using the flip connector or mounting hole. At the same time, the axial direction of the pivot hole on the flip connector and the axial direction of the mounting port ensure that when the hook of this utility model is used to hang the lamp horizontally, the drive component and the pushing component further apply force to the movable pressure plate, thereby ensuring the stability of the lamp when it is hung horizontally.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0080] The present invention will now be described in further detail with reference to the accompanying drawings.

[0081] Figures 5 to 7 The diagram schematically illustrates a quick-loading and unloading hook body according to one embodiment of the present invention, with reference to... Figures 5 to 7 As shown, the quick loading and unloading hook of this utility model includes a hook body 1, a fixed pressure plate 2 disposed on the hook body 1, a movable pressure plate 3 hinged to the hook body 1, a pushing member 5 hinged to the hook body 1, and a driving assembly 4 movably disposed on the hook body 1.

[0082] Specifically, the fixed pressure plate 2 has a first clamping part 21, and the movable pressure plate 3 has a second clamping part 31. The first clamping part 21 and the second clamping part 31 are arranged opposite to each other to form a clamping opening 13. The fixed pressure plate 2 is disposed on the hook body 1 and is fixedly connected to the hook body 1 by means of detachment or non-detachment, so that the fixed pressure plate 2 cannot move relative to the hook body 1, serving as the fixed end of the formed clamping opening 13. The movable pressure plate 3 is hinged to the first hinge point 11 of the hook body 1, so that the movable pressure plate 3 can rotate around the first hinge point 11, serving as the movable end of the formed clamping opening 13. In addition, in some possible embodiments, the hook body 1 may also be provided with an intermediate groove 14, the first hinge point 11 is located within the area of ​​the intermediate groove 14, and the movable pressure plate 3 is located within the intermediate groove 14, thereby using the hook body 1 to protect the structure of the movable pressure plate 3. For example, refer to... Figure 6 and Figure 7 As shown, in Figure 6 and Figure 7In the illustrated embodiment, the fixed pressure plate 2 is integrally formed and fixedly mounted on the hook body 1. The hook body 1 has a central groove 14, and a first hinge point 11 is located within the area of ​​the central groove 14, including a first pin fixing hole 111 penetrating 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 meet the requirements. The movable pressure plate 3 is disposed within the central groove 14, and its right end is hinged to the first pin 112 to achieve hinge at the first hinge point 11 on the hook body 1. By placing the movable pressure plate 3 within the central groove 14, the hinge position of the movable pressure plate 3 can be protected, and the structure of the movable pressure plate 3 can be protected. (Refer to...) Figure 6 As shown, it can also be further configured so that only the second clamping part 31 of the movable pressure plate 3 is exposed, so as to effectively avoid affecting the rotation of the movable pressure plate 3.

[0083] Regarding the first clamping part 21 and the second clamping part 31, the first clamping part 21 can be a clamping structure provided on the fixed pressure plate 2, such as an arc-shaped clamping surface. Similarly, the second clamping part 31 can be a clamping structure provided on the movable pressure plate 3, such as an arc-shaped clamping surface. For example, referring to... Figure 5 As shown, in Figure 5 In the illustrated embodiment, to facilitate clamping the steel pipe, both the fixed pressure plate 2 and the movable pressure plate 3 are arc-shaped. The first clamping part 21 on the fixed pressure plate 2 is located on the inner side of the arc, and the second clamping part 31 on the movable pressure plate 3 is also located on the inner side of the arc. (Refer to...) Figure 6 As shown, the fixed pressure plate 2 is shaped like a "V" with an arc forming at its intermediate transition position, so that the first clamping part 21 has two clamping surfaces, namely the X surface and the Y surface. The second clamping part 31 provided on the movable pressure plate 3 has one clamping surface, the Z surface. The X and Y surfaces on the fixed pressure plate 2 and the Z surface on the movable pressure plate 3 form a "C"-shaped structure, and the space they enclose forms the clamping opening 13. In this embodiment, with the clamping center of the clamping opening 13 as the center, the included angle between the three clamping surfaces is no greater than 180°, thereby ensuring the stability of the clamping opening 13 during clamping. The two clamping surfaces corresponding to the first clamping part 21 on the fixed pressure plate 2 and the one clamping surface corresponding to the second clamping part 31 on the movable pressure plate 3 can be provided with anti-slip structures to improve the friction during clamping, such as anti-slip textures or anti-slip rubber layers provided on these clamping surfaces, etc., which will not be listed in detail here.

[0084] The pushing member 5 is a structure used to push the movable pressure plate 3 to move. It is hinged to the second hinge point 12 on the hook body 1 and has a first pushing part 51. The first pushing part 51 is used to abut against the movable pressure plate 3, thereby pushing the movable pressure plate 3 to rotate, causing the second clamping part 31 to move closer to the first clamping part 21, thus narrowing the clamping opening 13 and clamping objects such as steel pipes. The first pushing part 51 on the pushing member 5 is the part that abuts against the movable pressure plate 3. For example, the first pushing part 51 can refer to a structure specifically provided on the pushing member 5, such as a boss provided on the pushing member 5, or it can refer to the contact surface on the side of the pushing member 5 facing the movable pressure plate 3 that will contact the movable pressure plate 3 (i.e., there is no special structure designed for the position that contacts the movable pressure plate 3). For example, refer to Figure 6 As shown, in Figure 6 In the embodiments shown, Figure 6 The left end of the pusher 5 is hinged at the second hinge point 12, and the first pusher part 51 is located at the right end of the pusher 5, that is, at the end of the pusher 5 away from the second hinge point 12. The second hinge point 12 is located in the area of ​​the intermediate groove 14, including a second pin fixing hole 121 penetrating the hook body 1 and a 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 meet the requirements, so that the pusher 5 can also be placed in the intermediate groove 14 to protect the structure of the pusher 5. (Refer to...) Figure 6 and Figure 7 As shown, the first pressing part 51 is specifically configured as an arc-shaped contact surface at the end of the pressing member 5 away from its hinge position. Correspondingly, a first slot 32 for abutting against the first pressing part 51 can be provided on the movable pressure plate 3 at the position where it abuts against the first pressing part 51. The shape of the first slot 32 is also configured as arc-shaped, and the length of the first slot 32 is longer to accommodate the change in the contact position between the first pressing part 51 and the first slot 32 when the movable pressure plate 3 rotates.

[0085] Regarding the contact point between the first pressing part 51 and the movable pressure plate 3, in some possible embodiments, this position can be set such that its distance from the first hinge point 11 is no greater than the distance between the first hinge point 11 and the second hinge point 12, i.e., it can be located near the first hinge point 11. This configuration significantly reduces the travel required for the first pressing part 51 to rotate when the pressing member 5 pushes the movable pressure plate 3, thereby reducing the travel distance of the drive assembly 4 and decreasing the overall clamping time. For example, referring to… Figure 6 As shown, in Figure 6In the embodiment shown, the first pressing part 51 of the pressing member 5 is disposed 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 pressure plate 3 is located near the first hinge point 11, so that the position where the first pressing part 51 abuts against the movable pressure plate 3 is as close as possible to the first hinge point 11, thereby greatly reducing the travel distance when the pressing member 5 pushes the movable pressure plate 3 to rotate.

[0086] The drive assembly 4 is a user-operated drive unit used to move the pusher 5. It is movably mounted on the hook body 1 and has a second pusher 44. The second pusher 44 abuts against the pusher 5, thereby pushing the pusher 5 to rotate. This causes the pusher 5 to push the movable pressure plate 3 to rotate, narrowing the clamping opening 13 and thus clamping objects such as steel pipes. The drive assembly 4 can be a structure commonly used in the art, such as a screw assembly or a pusher rod assembly. When the drive assembly 4 uses a screw assembly, the self-locking property of the thread can be used for locking. If the drive assembly 4 uses a pusher rod assembly, a separate locking mechanism is needed to lock the position of the drive assembly 4 to keep the clamping opening 13 clamped. (Refer to...) Figure 6 and Figure 7 As shown, in the embodiment where the drive assembly 4 adopts a screw assembly, the drive assembly 4 includes a drive member 41, a second pushing part 44 is disposed at the first end of the drive member 41, and the drive member 41 is provided with an external thread. The hook body 1 is provided with a threaded connection structure with an internal thread that mates with the external thread on the drive member 41. Thus, by cooperating with the drive member 41 through the threaded connection structure, the pusher 5 can be pushed to move by controlling the drive member 41 to move back and forth along the axis of the threaded hole of the threaded connection structure.

[0087] In some possible embodiments, the threaded connection structure can be a nut 42 fixed to the hook body 1 by welding or other methods. Alternatively, the threaded connection structure can be a threaded hole integrally formed on the hook body 1, thus ensuring the structural stability of the threaded connection structure. In other possible embodiments, the threaded connection structure can be a nut 42 detachably mounted on the hook body 1. Specifically, the hook body 1 can be provided with a nut mounting groove 15. The nut mounting groove 15 can be a through groove penetrating the hook body 1, or it can only penetrate to one side of the hook body 1 and connect to the intermediate groove 14. The nut 42 is detachably mounted on the nut mounting groove 15. (Refer to...) Figures 14 to 20 In the illustrated embodiment, the nut mounting slot 15 can be configured as a straight line, and the nut 42 can be square, thus adapting to the shape of the straight nut mounting slot 15, fixing the nut 42 relative to the hook body 1, preventing the nut 42 from moving. (Refer to...) Figures 21 to 27In the illustrated embodiment, the nut mounting groove 15 can also be circular, and the nut 42 can be cylindrical to fit the shape of the circular nut mounting groove 15. In this configuration, the nut 42 can rotate along the axis of the nut mounting groove 15, meaning the axis of the screw hole of the nut 42 can be rotated towards the first hinge point 11 or the second hinge point 12. This allows the position of the second pushing part 44 of the driving member 41 to be adjusted by rotating the nut 42. (Refer to...) Figures 5 to 13 In the illustrated embodiments, the nut mounting groove 15 can also be configured as a combination of circular and straight-line irregular hole structures, thus enabling the installation of both square and cylindrical nuts 42. It is understood that the nut mounting groove 15 provided on the hook body 1 in the above embodiments can be directly formed during the production of the hook body 1 through mold design. However, since the cost of re-molding is high, some existing hook body 1 molds can be modified to form the nut mounting groove 15 on the hook body 1 as described in this invention, or the structural style of the nut mounting groove 15 on the hook body 1 can be modified. (Refer to...) Figure 35 and Figure 36 As shown, at this time, the hook body 1 produced will have an opening 16 at the end away from the clamping port 13 that communicates with the nut mounting groove 15.

[0088] In some other possible embodiments, the threaded connection structure can also be a nut retainer 47 mounted on the hook body 1, see reference. Figures 28 to 34 In the embodiment shown, the nut fixing bracket 47 has a U-shaped cross section. The two sides of the nut fixing bracket 47 are symmetrically arranged, and each side is provided with two fixing holes, which are respectively installed at the first hinge point 11 and the second hinge point 12, so that the nut fixing bracket 47 is fixed on the hook body 1. The nut 42 is provided on the inner side of the middle part of the nut fixing bracket 47.

[0089] For the driving member 41, the second pressing portion 44 on the driving member 41 is a portion for contacting the pressing member 5. For example, the second pressing portion 44 can refer to a structure specifically provided on the driving member 41, such as a boss provided on the driving member 41, or it can refer to the contact surface on the driving member 41 that will contact the pressing member 5 (i.e., there is no special structure designed for the position for contacting the pressing member 5). For example, refer to... Figure 6 and Figure 7 As shown, in Figure 6 and Figure 7In the illustrated embodiment, the second pressing part 44 is specifically configured as an arc-shaped surface at the first end of the driving member 41. Correspondingly, in some embodiments, a second slot (not shown in the figures) for abutting against the second pressing part 44 can also be provided on the pressing member 5 at the position where it abuts against the second pressing part 44. The shape of the second slot can also be configured as arc-shaped, and the length of the second slot is longer to accommodate the change in the contact position between the second pressing part 44 and the second slot when the movable pressure plate 3 rotates. The shape of the second slot can also be adapted to the shape of the second pressing part 44, thereby cooperating with the design of the rotatable cylindrical nut 42, so that when the driving member 41 moves toward the pressing member 5, the contact position between the second pressing part 44 and the pressing member 5 remains unchanged, ensuring that the angle of rotation of the pressing member 5 driven by a unit stroke remains unchanged.

[0090] Regarding the contact position 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 no 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 lever pushes the pressing member 5 to rotate can be greatly reduced. At this time, combined with the reduction in the stroke of the pressing member 5 driving the movable pressure plate 3 to rotate, the stroke reduction rates of the two can be multiplied and superimposed, thereby achieving a significant reduction in the moving stroke of the driving component 4 and a significant reduction in the overall clamping time. If it is set in the middle between the first hinge point 11 and the second hinge point 12, it is easier to push the pressing member 5 with the operating driving member 41. In this approach, since the travel distance has already been optimized by the contact position between the first pushing part 51 and the movable pressure plate 3, further optimization of the travel distance is less effective. Therefore, by optimizing the labor-saving portion, the overall structure can effectively balance labor and time saving, and is less likely to affect other structural designs of the lamp, thus balancing practicality and aesthetics. Furthermore, this method is more convenient for processing and assembly. For example, referring to… Figure 6 As shown, in Figure 6 In the embodiment shown, the second pushing part 44 of the driving member 41 is disposed in the middle between the first hinge point 11 and the second hinge point 12, thereby making it easier to operate the driving member 41 and making the overall structure both labor-saving and time-saving.

[0091] In some possible embodiments, the drive member 41 may also be provided with a screw head structure for turning the drive member 41. The screw head structure makes it easier and less strenuous for the user to turn the drive member 41. In other possible embodiments, a first elastic member 43 is provided between the screw head structure and the threaded connection structure. The first elastic member 43 prevents loosening of the fit between the drive member 41 and the threaded connection structure, thereby improving stability during clamping. For example, see... Figure 6 and Figure 7 As shown, in this embodiment, the first elastic element 43 is a spring, and the second pushing part 44 of the driving member 41 passes through the first elastic element 43 and the threaded connection structure in sequence and pushes against the pushing member 5. Meanwhile, in Figure 6 and Figure 7 In the illustrated embodiment, the screw head structure is configured such that a movable handle 45 passes through the drive member 41 in a direction perpendicular to the axis of the drive member 41, thereby adapting to various narrow operating spaces and facilitating the user to screw the drive member 41. (Refer to...) Figures 14 to 20 The embodiments shown and Figures 28 to 34 The embodiment shown illustrates another possible screw head structure provided on the drive member 41, which is configured as a fixed handle 46 fixed to the end of the drive member 41 away from the second pressing part 44.

[0092] In some possible implementations, the quick-release hook of this invention can also have a second elastic element 6 provided between the hook body 1 and the movable pressure plate 3. The second elastic element 6 is used to drive the movable pressure plate 3 to rotate, so that the second clamping part 31 moves away from the first clamping part 21, and the clamping opening 13 maintains the maximum opening angle. The second elastic element 6 can be a tension spring or a torsion spring, or other commonly used elastic element structures. The first end of the second elastic element 6 is fixed to the hook body 1, and the second end is fixed to the movable pressure plate 3. Specifically, the movable pressure plate 3 can be provided with a connecting structure for connecting to the second elastic element 6, and the hook body 1 can also be provided with a connecting structure for connecting to the second elastic element 6. These connecting structures can be configured by providing protrusions to form a structure for hooking the second elastic element 6, or by providing recesses to form a structure for hooking the second elastic element 6, or by providing screws 61, hooks, or other structures on their surfaces to form a structure for hooking the second elastic element 6. Correspondingly, the second elastic element 6 can be provided with a corresponding hooking hole structure. For example, refer to... Figure 7 As shown, in Figure 7In the illustrated embodiment, the second elastic element 6 is a tension spring with a circular hole at its first end and a square hole at its second end. A protrusion and an elastic element fixing groove 33 are provided on the movable pressure plate 3 at the end away from the second clamping part 31. A screw 61 is threaded onto the hook body 1 near the fixed pressure plate 2. The circular hole of the tension spring hooks onto the screw 61, and the square hole hooks onto the elastic element fixing groove 33, thereby pulling the end of the movable pressure plate 3 away from the second clamping part 31 towards the fixed pressure plate 2, causing the movable pressure plate 3 to rotate, thus moving the second clamping part 31 away from the first clamping part 21, and keeping the clamping opening 13 at its maximum opening angle.

[0093] In some possible embodiments, the hook body 1 may also be provided with a flip connector 71 and / or mounting hole 72 for connecting to the lamp base. When the hook body 1 is provided with a flip connector 71, the flip connector 71 includes at least two legs 711, each leg 711 having a pivot hole 712. The pivot holes 712 on each leg 711 are coaxially arranged, and the plane containing the axis of the pivot hole 712 is parallel to the plane containing the axis of the clamping opening 13. This arrangement ensures that when the hook body 1 is used to hang the lamp horizontally, the driving assembly 4 and the pushing member 5 further apply force to the movable pressure plate 3, thereby ensuring the stability of the lamp when it is hung horizontally. When the hook body 1 is provided with a mounting hole 72, the mounting hole 72 can be used to install various detachable flip connection structures. Specifically, the plane containing the axis of the mounting hole 72 is perpendicular to the plane containing the axis of the clamping opening 13, thereby ensuring that when the hook 1 of this utility model is used to hang the lamp horizontally, the driving component 4 and the pushing component 5 further apply force to the movable pressure plate 3, thus ensuring the stability when the lamp is hung horizontally. For example, refer to... Figure 5 , Figure 15 , Figure 21 , Figure 28 As shown, this illustrates the structure of a hook body 1 equipped with a flip connector 71. One end of the hook body 1 extends away from the fixed pressure plate 2, and the flip connector 71 is disposed in this extended portion. The flip connector 71 includes two legs 711, each with a pivot hole 712. The two pivot holes 712 are coaxially arranged, and the plane containing their axes is parallel to the plane containing the axis of the clamping opening 13. (Refer to...) Figures 8 to 10 , Figure 16 and Figure 17 , Figure 23 and Figure 24 , Figure 30 and Figure 31 As shown, Figure 13The structure of a hook body 1 with a mounting hole 72 is shown. The end of the hook body 1 extends away from the fixed pressure plate 2. The mounting hole 72 is provided in the extended part, and the plane containing the axis of the mounting hole 72 is perpendicular to the plane containing the axis of the clamping port 13.

[0094] Figures 11 to 13 , Figures 18 to 20 , Figures 25 to 27 , Figures 32 to 34 The diagrams schematically illustrate the structures of hooks 1 with different flip-connection structures mounted on mounting holes 72, for reference. Figure 11 , Figure 18 , Figure 25 and Figure 32 As shown, the flip-connecting structure includes a first flip-connector 73, which is a U-shaped piece with a flat bottom and symmetrical and parallel sides. It includes two connecting edges 731 and a mounting base 732. The two connecting edges 731 are arranged parallel to each other and spaced apart. The two ends of the mounting base 732 are connected to the same side ends of the two connecting edges 731, respectively. The ends of the two connecting edges 731 furthest from the mounting base 732 are semi-circular. Each connecting edge 731 has a first pivot hole 733, which is concentric with the semi-circle. A through hole is provided at the center of the mounting base 732. A bolt passes through the through hole, an elastic washer, and the mounting hole 72 on the hook body 1 in sequence, and is then fastened to the mounting nut. When a large external force is applied, the first flip-connector 73 can rotate around the center of the bolt.

[0095] Reference Figure 12 , Figure 19 , Figure 26 and Figure 33 As shown, the flip-connecting structure includes a second flip-connector 74, which is an integrally cast part. It includes two connecting legs 741 and studs positioned above the two connecting legs 741. The two connecting legs 741 have second pivot holes 742, which are coaxial. The stud passes sequentially through an elastic washer, a mounting hole 72 on the hook body 1, and is then securely connected to a mounting nut. Under strong force, the second flip-connector 74 can rotate around the center of the stud.

[0096] Reference Figure 13 , Figure 20 , Figure 27 and Figure 34 As shown, the flip connection structure includes a hexagonal bolt 75, which passes through the mounting hole 72 on the hook body 1. A flat washer and a spring washer are then placed on top of each other, and the mounting nut 76 is screwed on. The mounting nut 76 can be a wing nut or a hexagonal nut.

[0097] The quick-loading hook of this utility model is equipped with a pushing member 5. The pushing member 5 is pushed by the control drive assembly 4, and the pushing member 5 further pushes the movable pressure plate 3 to rotate, so that the clamping opening 13 is reduced and the steel pipe is clamped. In this design, the rotation of the movable pressure plate 3 relies on pushing the pushing member 5. By simply adjusting the contact position between the first pushing part 51 on the pushing member 5 and the movable pressure plate 3, the clamping time of the lamp hook can be adjusted. For example, adjusting the contact position between the first pushing part 51 on the pushing member 5 and the movable pressure plate 3 to near the first hinge point 11 can significantly reduce the clamping time of the lamp hook. Since the drive assembly 4 drives the pusher 5 to rotate by abutting against the pusher 5 via the second pusher 44, the contact position between the second pusher 44 and the pusher 5 can be adjusted as needed. When it is necessary to further shorten the clamping time, the contact position between the second pusher 44 and the pusher 5 can be adjusted to be closer to the second hinge point 12. Conversely, if it is necessary to make it easier for the user to operate the drive assembly 4 for clamping, the contact position between the second pusher 44 and the pusher 5 can be adjusted to be further away from the second hinge point 12. In addition, the quick-release hook of this invention does not rely on the elastic deformation of certain structural components to achieve clamping, thereby effectively improving the reliability of clamping when hanging lamps horizontally. Furthermore, since the quick-release hook of this invention can effectively shorten the clamping time, it can effectively reduce the travel of the drive assembly 4, thereby reducing the overall size of the hook 1 and effectively reducing the occurrence of interference with the machine feet.
