Description

Technical Field

[0001] The utility model relates to the technical field of soft boxes, in particular to a portable chuck soft box. Background Art

[0002] A softbox is a piece of photographic equipment consisting of a reflective sheet, a diffuser, a wire frame, and a mount. It can't be used alone; it's an accessory for studio lights. The mount connects the softbox to the studio light, so there are various mounts available to accommodate a variety of studio lights. When attached to a studio light, the softbox produces a softer light, eliminating flare and shadows in photos.

[0003] Most softboxes are foldable and removable, making them easy to pack and transport. They can be opened and propped up for use. Currently, softboxes on the market offer a variety of folding options. For example, Chinese utility model application number CN202211174217.5 discloses a softbox base and a softbox. The softbox base comprises a chuck with a plurality of slots spaced circumferentially; a plurality of connectors corresponding to the slots, each connector including a first end and a second end, the first end rotatably connected to the corresponding slot; and a plurality of stopper assemblies movably disposed in the slots. The stopper assemblies include abutment portions. The connectors can be rotated relative to the chuck to a first position, where the first ends of the connectors abut against the abutment portions, thereby locking the connectors. The stopper can be moved to release the abutment portions from the first ends, allowing the connectors to rotate relative to the chuck to a second position. Without applying external force to the stopper, the connectors can be rotated in the second position, pressing against the abutment portions of the stopper assemblies and returning to the first position. It is not difficult to see from the utility model manual that when the soft box is stored, it is necessary to control the limit components one by one to unlock them, which is a rather cumbersome operation.

[0004] The Chinese utility model patent application number CN202311484104.X discloses a quick-lock softbox chuck, comprising: an umbrella tray seat, which is annular and has at least two through-grooves on its lower surface; a plurality of first support seats and a second support seat, which are movably connected to the umbrella tray seat, with the second support seat located in the through-grooves; a locking unit, which has a locked state and an unlocked state. In the locked state, the second support seat is unfolded relative to the umbrella tray seat, and in the unlocked state, the second support seat is flipped to the bottom of the umbrella tray seat through the through-grooves, so that the softbox is flat. The second support seat of the softbox chuck of this utility model can be unfolded or flipped relative to the umbrella tray seat, and its first support seat can also rotate circumferentially. In actual use, this type of quick-lock softbox chuck with a flippable support seat has a large flipping switching force and is more suitable for use with small softboxes. Utility Model Content

[0005] (1) Technical issues to be resolved

[0006] The problem to be solved by the utility model is to provide a portable chuck soft box to overcome the defects in the prior art.

[0007] (2) Technical solution

[0008] In order to solve the technical problem, the utility model provides a portable chuck softlight box, comprising a chuck body, wherein the upper limit of the chuck body is installed with a first support rod for connecting a soft light cloth, the chuck body is provided with a sliding groove along the circumferential direction, and a second support rod for connecting the soft light cloth is slidably installed in the sliding groove, and the second support rod can be rotated relative to the first support rod along the circumferential direction to open or fold, and a locking piece is also provided on one side of the sliding groove; when the softlight box is opened for use, the second support rod is rotated forward to open it relative to the first support rod along the circumferential direction, and the inner end of the second support rod slides in the sliding groove until the second support rod is engaged with the locking piece; when the softbox is folded, the second support rod is disengaged from the locking piece, and the second support rod is rotated in the opposite direction to move it toward the first support rod and fold it, and the second support rod synchronously slides toward the side close to the first support rod in the sliding groove.

[0009] In this solution, a sliding groove is provided on the outside of the chuck body, allowing the second support rod to slide within the groove and expand or collapse relative to the first support rod. A soft light cloth is connected to the first and second support rods. When the second support rod is expanded relative to the first support rod, the soft light cloth can be spliced together to form a complete soft light box. The direction in which the second support rod expands or collapses relative to the first support rod is the circumferential direction of the chuck body. When collapsed, the second support rod moves toward the side of the first support rod, making it easier to store.

[0010] In some embodiments, the first support rod and the second support rod are arranged in pairs; an opening is provided on the outer edge of the chuck body, and the sliding groove is provided in the opening; and / or the sliding groove is provided concentrically with the chuck body, and one end of the second support rod forms a spherical surface that cooperates with the sliding groove.

[0011] In this solution, the second support rod is movably installed at the opening, and the opening is set in the circumferential direction. The spherical hinge at one end of the second support rod is installed in the sliding groove, which facilitates the rotation of the second support rod in the circumferential direction. It can slide in the sliding groove, and after being folded, it is convenient to reduce the storage area of the soft box and facilitate packaging.

[0012] In some embodiments, the locking member forms a locking groove, and the second support rod can be locked into the locking groove; and / or, one side of the locking member forms a guide surface for guiding the second support rod into the locking groove.

[0013] In this solution, the locking member is used to position and fix the second support rod in the locking groove when the soft box is opened; the opening width is larger than the size of the second support rod, and one end of the second support rod is spherical, so the second support rod can also swing appropriately in the radial direction; when the soft box is folded, the second support rod is lifted up to disengage it from the locking groove; when the soft box is opened for use, the second support rod can enter the locking groove along the guide surface for limiting.

[0014] In some embodiments, a self-locking mechanism is also provided on one side of the second support rod; the self-locking mechanism includes a positioning protrusion provided at the lower end of the second support rod and a positioning groove provided on the chuck body; or: the self-locking mechanism includes a positioning groove provided at the lower end of the second support rod and a positioning protrusion provided on the chuck body.

[0015] In this solution, since the second support rod can slide in the sliding groove, when the second support rod enters the locking groove, under extreme circumstances, the second support rod may have a certain displacement in the locking groove (which does not affect normal opening and folding). Therefore, this solution is also designed with a self-locking mechanism, which ensures that the second support rod can be accurately locked and positioned in the locking groove by cooperating with the positioning groove and the positioning protrusion.

[0016] In some embodiments, there are two locking members, which are symmetrically installed on the chuck body; and / or, a zipper or Velcro is correspondingly provided on the soft light cloth on one side of the second support rod. When the soft light box is opened for use, the soft light cloths on the two second support rods are connected together by the zipper or Velcro to form the soft light box.

[0017] In this solution, the first support rod, the second support rod, and the locking piece are all symmetrically arranged on the chuck body, and the first support rod and the second support rod are installed with the same piece of soft light cloth; when the soft light box is opened, the second support rod needs to be engaged with the locking piece, and the soft light cloth will be relatively closed at this time, and the soft light cloth can be completely connected by setting a zipper or Velcro and other structures to support the soft light box.

[0018] In some embodiments, at least one third support rod is hingedly installed at the opening; when the softbox is folded, the third support rod rotates toward the first support rod; the third support rod has the same structure as the second support rod.

[0019] In this solution, the third support rod can only rotate and cannot slide; it is suitable for use with octagonal or hexagonal softboxes.

[0020] In some embodiments, the softbox is an octagonal softbox, and the chuck body is further provided with a fourth support rod that can rotate toward the first support rod on the side close to the first support rod; the number of the first support rod, the second support rod, the third support rod and the fourth support rod are two.

[0021] In this solution, the softbox is an octagonal softbox, suitable for small to medium-sized applications. It's important to note that the fourth support rod can also be designed with the same structure as the second and third support rods. The fourth support rod can also be folded toward the first support rod. Since all support rods of an octagonal softbox are connected to the same diffuser, locking the second support rod in place with a locking member allows the entire softbox to be supported.

[0022] In some embodiments, the softbox is a hexagonal softbox, the number of the first support rods is four, the number of the second support rods is ten, the number of the third support rods is two, and the outermost second support rod is used to engage with the locking member.

[0023] In this solution, the softbox is a hexagonal softbox suitable for large-scale use. Multiple second support rods are slidably mounted within the sliding grooves, so that when the softbox is folded, the second support rods can be folded toward the first support rods along the sliding grooves, thereby reducing the packing size.

[0024] In some embodiments, the chuck body includes an upper chuck and a lower chuck, and the upper chuck and the lower chuck are spliced to form the sliding groove; the locking member is provided on the lower chuck.

[0025] In this solution, the sliding groove is formed by splicing the upper chuck and the lower chuck, and the entire soft box involves fewer parts and is easy to assemble.

[0026] In some embodiments, the second support rod is approximately L-shaped, with one end being spherical; one end of the first support rod is also spherical; and the soft light cloth is further provided with a strap for storage.

[0027] In this solution, the first support rod is limited to the installation cavity of the chuck body, and the first support rod can only swing up and down a certain amount to facilitate supporting the soft box.

[0028] (3) Beneficial effects

[0029] The portable chuck soft box provided by the present invention has the following advantages over the prior art:

[0030] The utility model is easy to assemble and involves few parts. By arranging a sliding groove on the chuck body and setting one end of the second support rod into a spherical surface, it can slide in the sliding groove and can be rotated relative to the first support rod to open or close, thereby realizing the folding function of the soft box; by arranging the sliding groove, the second support rod can be moved toward the first support rod when the soft box is folded. At this time, the second support rod is basically on the side of the chuck body close to the first support rod. When the soft box is opened, the second support rod is on the side of the chuck body away from the first support rod; the soft box is suitable for octagonal soft boxes and hexagonal soft boxes, and can also be used for quadruple soft boxes. Corner softbox, the opening operation of the softbox is more labor-saving; the utility model provides a locking piece, which can lock the second support rod in position on the chuck body when the softbox is opened; by providing a self-locking mechanism, the positioning protrusion and the positioning groove cooperate to ensure that the second support rod can be accurately positioned in the locking groove of the locking piece; the support rods on the chuck body of the utility model are symmetrically arranged, and two locking pieces are provided, which decompose the force of supporting the softbox to the left and right sides. When supporting the softbox, the second support rods on both sides can be pushed into the locking grooves. The force of supporting the softbox does not need to be very large, and the operation is labor-saving. It is suitable for softboxes of different specifications such as square, octagonal and hexagonal. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] The following describes the technical solutions provided by various embodiments of the present application in conjunction with the accompanying drawings.

[0054] See Figures 1 to 15 The utility model provides a portable chuck soft box, comprising a chuck body 1 and a soft cloth; a first support rod 2 for connecting the soft cloth is installed at the upper limit of the chuck body 1, and a sliding groove 101 is provided along the circumferential direction of the chuck body 1, and a second support rod 3 for connecting the soft cloth is slidably installed in the sliding groove 101, and the second support rod 3 can be rotated relative to the first support rod 2 along the circumferential direction to open or fold; a locking member 4 is also provided on one side of the sliding groove 101, and the locking member 4 is used to position the second support rod 3; Figure 1 and Figure 11 As shown, the first support rod 2 , the second support rod 3 , and the locking member 4 are all symmetrically arranged on the chuck body 1 .

[0055] In the embodiments of this specification, the forward direction is defined as the direction of movement toward the locking member 4 in the circumferential direction, and the reverse direction is defined as the direction of movement toward the first support rod 2 in the circumferential direction. The two directions correspond to the opening and folding directions of the softbox's diffuser.

[0056] When the softbox is opened for use, the second support rod 3 is rotated forward to open relative to the first support rod 2 along the circumferential direction. At the same time, the inner end of the second support rod 3 (a spherical surface) will slide in the sliding groove 101 toward the side of the locking member 4 until the second support rod 3 is engaged with the locking member 4 (as shown in FIG. Figure 4 When the softbox is folded, the second support rod 3 is released from the locking member 4, and the second support rod 3 is rotated in the opposite direction to be folded toward the first support rod 2. The second support rod 3 simultaneously slides toward the side close to the first support rod 2 in the sliding groove 101 (as shown). Figure 5 As shown), the folded second support rod 3 will move closer to the first support rod 2 for easy storage.

[0057] The sliding groove 101 is set on the outside of the chuck body 1, and the outer edge of the chuck body 1 is provided with an opening 102, and the sliding groove 101 is set in the opening 102; the second support rod 3 of this embodiment can not only slide in the sliding groove 101, but also rotate in the circumferential direction relative to the first support rod 2, which is used to open and fold the soft light cloth of the soft light box. The first support rod 2 and the second support rod 3 are connected to the same soft light cloth. After the second support rod 3 is unfolded relative to the first support rod 2, the soft light cloth can be spliced to form a complete soft light box (such as Figure 13 and Figure 14 shown).

[0058] In this embodiment, the opening 102 and the sliding groove 101 are provided so that the second support rod 3 can move (displace and swing) along the circumferential direction of the chuck body 1 at the opening 102 .

[0059] In some embodiments, the first support rod 2 and the second support rod 3 are arranged in pairs; Figure 2 、 Figure 7 and Figure 8 , the sliding groove 101 is arranged concentrically with the chuck body 1; Figure 2 and Figure 6 , one end of the second support rod 3 forms a spherical surface that matches the sliding groove 101. Figure 4-Figure 6 As shown, the spherical surface at one end of the second support rod 3 is hingedly installed in the sliding groove 101, which facilitates the second support rod 3 to rotate in the circumferential direction, and it can slide in the sliding groove 101, and after being folded, it is convenient to reduce the storage area of the soft box.

[0060] like Figure 1 and Figure 7As shown, in some embodiments, the locking member 4 forms a locking groove 401, into which the second support rod 3 can be snapped; the locking member 4 is used to position and secure the second support rod 3 in the locking groove 401 when the softbox is opened. The width of the opening 102 is larger than that of the second support rod 3, and one end of the second support rod 3 is spherical, so that the second support rod 3 can also swing appropriately in the radial direction (facilitating lifting the second support rod 3 so that it enters the locking groove 401 of the locking member 4). When the softbox is folded, the second support rod 3 is lifted to disengage the locking groove 401.

[0061] In this embodiment, the force for supporting the soft box is decomposed to the left and right sides. When supporting the soft box, it is only necessary to push the second support rods 3 on both sides into the locking grooves 401 respectively, and the force for supporting the soft box does not need to be very large.

[0062] like Figure 7 As shown, one side of the locking member 4 forms a guide surface for guiding the second support rod 3 into the locking groove 401. When the soft box is opened for use, the second support rod 3 can enter the locking groove 401 along the guide surface for position limiting.

[0063] like Figure 9 As shown, a self-locking mechanism 7 is further provided on one side of the second support rod 3 for further positioning the second support rod 3 on the locking member 4 .

[0064] In one example, Figure 6 and Figure 7 As shown, the self-locking mechanism 7 includes a positioning protrusion 701 provided at the lower end of the second support rod 3 and a positioning groove 702 provided on the chuck body 1 (at the opening 102). The positioning groove and the positioning protrusion cooperate to ensure that the second support rod 3 can be accurately locked and positioned in the locking groove 401.

[0065] In another embodiment (not shown in the figures), the positioning groove 702 of the self-locking mechanism 7 can be provided at the lower end of the second support rod 3 , and the positioning protrusion 701 can be provided on the chuck body 1 .

[0066] In some embodiments, as Figure 2 and Figure 11 As shown, there are two locking members 4, which are symmetrically mounted on the chuck body 1; Figure 13-15 As shown, a zipper 8 or Velcro is provided on the soft light cloth on one side of the second support rod 3. When the soft light box is opened for use, the second support rod 3 needs to be snapped onto the locking member 4 first. At this time, the soft light cloth will be relatively closed. Then, the soft light cloths on the two second support rods 3 are connected together by the zipper 8 or Velcro to support the soft light box (as shown in FIG. Figure 15 shown).

[0067] In some embodiments, as Figure 2As shown, the chuck body 1 includes an upper chuck 103 and a lower chuck 104, and the upper chuck 103 and the lower chuck 104 are spliced to form a sliding groove 101; Figure 7 As shown, the locking member 4 is arranged on the lower chuck 104. The sliding groove 101 is formed by splicing the upper chuck 103 and the lower chuck 104. The entire soft box involves fewer parts and is easy to assemble.

[0068] In some embodiments, as Figure 2 and Figure 6 As shown, the second support rod 3 is approximately L-shaped, with one end being spherical; one end of the first support rod 2 is also spherical, and the first support rod 2 is limited to the mounting cavity 105 of the chuck body 1, and the height of the mounting cavity 105 is greater than the height of the first support rod 2, so the first support rod 2 can swing up and down to a certain extent, which is convenient for supporting the soft box; when supporting the soft box, the soft cloth will not be too tight, which will make it difficult for the second support rod 3 to be stuck into the locking groove 401.

[0069] like Figure 15 As shown, Figure 15 The figure shows the actual object of the octagonal soft box when it is expanded. The soft cloth is connected by a zipper 8 and is also provided with a strap for storage.

[0070] In one embodiment, the chuck body 1 is used on a four-corner softbox; Figure 12 As shown, the chuck body 1 of the soft box includes two first support rods 2 and two second support rods 3.

[0071] In one embodiment, if Figures 1-9 , Figure 13 and Figure 15 As shown, the chuck body 1 is used on an octagonal softbox; a third support rod 5 is hingedly installed at the opening 102; when the softbox is folded, the third support rod 5 rotates toward the first support rod 2; in this embodiment, the third support rod 5 has the same structure as the second support rod 3; the difference is that the third support rod 5 can only rotate and cannot slide. The chuck body 1 is also provided with a fourth support rod 6 on the side close to the first support rod 2, which can rotate toward the first support rod 2. In this embodiment, Figure 3 As shown, the chuck body 1 is provided with an escape cavity 106 for accommodating the fourth support rod 6. The first support rod 2, the second support rod 3, the third support rod 5, and the fourth support rod 6 are each provided in two pieces. It should be noted that the fourth support rod 6 can also be designed with the same structure as the second support rod 3 and the third support rod 5; the fourth support rod 6 can also be folded toward the first support rod 2. The support rods of the octagonal softbox are all connected to the same diffuser fabric. Therefore, once the second support rod 3 is locked in place by the locking member 4, the entire softbox can be supported.

[0072] In one embodiment, if Figure 11 、 Figure 12 and Figure 14 As shown, the chuck body 1 is used on a hexagonal softbox. A third support rod 5 is also hingedly mounted at the opening 102. When the softbox is folded, the third support rod 5 rotates toward the first support rod 2. In this embodiment, there are four first support rods 2 and ten second support rods 3 (when the softbox is folded, each of the second support rods 3 can slide within the sliding groove 101, allowing them to be moved as close as possible to the first support rod 2 when stored). There are two third support rods 5, with the outermost second support rod 3 engaging with the locking member 4. The support rods of the hexagonal softbox are all connected to the same diffuser fabric. Therefore, once the outermost second support rod 3 is locked in place with the locking member 4, the entire softbox can be supported.

[0073] The same or similar parts between the various embodiments in this specification can be referred to each other, and each embodiment focuses on the differences from other embodiments.

[0074] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
