Thus, the appearances of the phrases "in one embodiment" or "in some embodiments" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

As described in the background art, in the prior art, when a large-sized accessory is mounted on the light-emitting side of the movie lamp, the accessory shields the operating portion of the push rod mechanism, which makes it inconvenient to detach the accessory.

In order to solve the above problems, an embodiment of the present invention provides a movie lamp, please refer to fig. 1-7, which includes a housing 1, a push rod 2, and a bracket 3. The housing 1 is provided with a first through hole 111 whose axial direction is parallel to the light emitting direction of the movie lamp. The housing 1 is further provided with a second through hole 121, and an included angle is formed between the axis of the second through hole 121 and the axis of the first through hole 111. The push rod 2 is inserted into the first through hole 111 and can move along the axial direction of the first through hole 111. The bracket 3 is disposed between the first through hole 111 and the second through hole 121, that is, the bracket 3 is movable relative to the housing 1 between the first through hole 111 and the second through hole 121. For example, the pressing or stretching movement along the axial direction of the second through hole 121 may be performed, but it is also possible to slide or rotate the bracket 3 relative to the housing 1 through the adapter structure. The first end of the holder 3 is provided with an inclined section 31 and the second end of the holder 3 extends to the second through hole 121. One end of the push rod 2 facing the inside of the shell 1 is connected with the inclined section 31 in a sliding mode, and the axial direction of the push rod 2 and the plane of the inclined section 31 form an acute angle. The acute angle does not include 0 degree and 90 degrees, and taking the minimum angle of the axis of the push rod 2 and the plane of the inclined section 31 as an example, the specific angle can be determined by the movement stroke of the push rod 2 relative to the first through hole 111, that is, the movement stroke of the push rod 2.

One end of the push rod 2 facing the inside of the housing 1 is slidably mounted on the inclined section 31. It should be mentioned that the second end of the bracket 3 is used for receiving an external force to make the bracket 3 move relative to the housing 1 along an axis parallel to the second through hole 121, and when the bracket 3 moves, the bracket 3 drives the end of the push rod 2 facing the inside of the housing 1 to slide on the inclined section 31 toward the second end of the bracket 3, so as to drive the push rod 2 to move telescopically relative to the first through hole 111. It will be appreciated that during movement there may be surface contact between the inclined section 31 and the push rod 2, either directly or indirectly. As shown in fig. 2, the inclined surface of the inclined section 31 may be inclined from right to left along the axial direction of the second through hole 121 (i.e. the inclined surface of the inclined section 31 faces to the left), and when the second end of the bracket 3 is pressed, the push rod 2 is retracted into the first through hole 111, and if the bracket 3 is not pressed, the push rod 2 extends out of the first through hole 111. Also taking fig. 2 as an example, it is needless to say that the inclined surface of the inclined section 31 may be inclined from left to right along the axial direction of the second through hole 121 (i.e. the inclined surface of the inclined section 31 faces to the right), and in this case, for example, the second end of the pull-out bracket 3 may be used, the push rod 2 is retracted into the first through hole 111, and if the pull-out bracket 3 is not pulled out, the push rod 2 extends out of the first through hole 111. As long as the specific tilt direction can be matched with the movement direction of the actual operating bracket 3. For example, there may be a case where the bracket 3 slides in a direction perpendicular to the axis of the second through hole 121 so that the force component of the inclined section 31 drives the push rod 2 to move.

In the embodiment of the present application, the housing 1 is provided with a first through hole 111 and a second through hole 121, and the push rod 2 is inserted into the first through hole 111. A bracket 3 is provided between the first through hole 111 and the second through hole 121, and one end of the push rod 2 facing the inside of the housing 1 is slidably mounted on the inclined section 31 of the bracket 3. When the accessories on the movie lamp need to be detached, a user can apply an external force to the second end of the bracket 3, so that the bracket 3 moves relative to the housing 1 along the axial direction parallel to the second through hole 121, and the push rod 2 is driven to move relative to the first through hole 111 through a component force in the axial direction of the push rod 2 generated by the transverse movement of the inclined section 31. Therefore, the second through hole 121 can be arranged at other positions forming an included angle with the first through hole 111, so that the second through hole 121 cannot be shielded by a large-sized accessory, a user can apply external force to the second end of the bracket 3 through the second through hole 121, the operation process cannot be interfered by the accessory, the operation is easy, and the accessory can be conveniently detached.

In some embodiments, the casing 1 may include a front wall 11 and a side wall 12 disposed around the front wall 11, the first through hole 111 is disposed on the front wall 11, the second through hole 121 is disposed on the side wall 12, an axis of the second through hole 121 is perpendicular to an axis of the first through hole 111, the bracket 3 includes a first connecting section 32, the first connecting section 32 is parallel to an axis of the second through hole 121 and is slidably connected with respect to the front wall 11, and the first connecting section 32 is connected with the inclined section 31 and is not coplanar. It will be appreciated that the first connecting portion 32 may be directly subjected to the force applied from the second end of the bracket 3 and transmitted to the inclined portion 31, and in a simplest principle, the first connecting portion 32 may be a part of the second end of the bracket 3 and partially leak out of the second through hole 121, for example, the first connecting portion 32 is operated to drive the inclined portion 31 to slide relative to the push rod 2, and of course, in a more complicated structure, the first connecting portion 32 may be only a part of the bracket 3, and the bracket 3 may also include other structures described in the following embodiments.

It can be understood that the front wall 11 of the housing 1 is provided with a bayonet for fixing accessories such as a soft light box or a light shield, for example, the accessories are provided with a bayonet holder, the bayonet holder can be a bayonel bayonet or other multi-point bayonet, and the first through hole 111 is opened in the bayonet holder. When the accessory is arranged on the light-emitting side of the movie lamp, the front wall 11 of the shell 1 is opposite to the accessory. When the accessory is installed on the bayonet, the push rod 2 can be controlled to move in the first through hole 111, so that one end, facing the outside of the shell 1, of the push rod 2 extends out of the first through hole 111 and is fixed with the accessory, the accessory is locked, and the accessory is prevented from falling off from the movie lamp.

Illustratively, when it is desired to detach the accessory from the movie lamp, the user may apply an external force to the second end of the bracket 3, the direction of the external force being toward the inside of the housing 1 along the axis of the second through hole 121. It will be appreciated that the force applied to the second end of the bracket 3 may be transmitted from the first connecting section 32 to the inclined section 31. Of course, the first through hole 111 may play a role of limiting the push rod 2, i.e. limiting the push rod 2 from moving along the radial direction of the first through hole 111. The push rod 2 can be provided with an inclined surface corresponding to the inclined section 31, the inclined surface can be in surface contact with the inclined section 31, when the support 3 slides, the inclined section 31 drives one end of the push rod 2 facing the inside of the shell 1 to slide towards the second end of the support 3 on the inclined section 31, and then one end of the push rod 2 facing the outside of the shell 1 is driven to move to the inside of the first through hole 111 so as to unlock the accessory, so that the accessory can be detached.

In some embodiments, please refer to fig. 5 and fig. 6, as a specific implementation manner of the movie lamp provided by the embodiment of the present application, an axis of the second through hole 121 is perpendicular to an axis of the first through hole 111, so that when an external force is applied to the second end of the bracket 3, an end of the push rod 2 facing the inside of the housing 1 slides on the inclined section 31 along an inclined direction of the inclined section 31.

Specifically, the axis of the second through hole 121 extends in the X-axis direction in fig. 6, the axis of the first through hole 111 extends in the Y-axis direction in fig. 6, and the X-axis direction is perpendicular to the Y-axis direction. Wherein, the positive direction of the Y axis is the light emitting direction of the film and television lamp. When external force acts on the bracket 3, the bracket 3 can be driven to move along the positive direction of the X axis, and the push rod 2 slides on the inclined section 31 along the inclined direction of the inclined section 31 towards one end of the inner part of the shell 1 under the limiting action of the first through hole 111. When the annex on the movie & TV lamp was dismantled to needs, the user can apply towards the inside external force of casing 1 to the second end of support 3 along the light-emitting direction of perpendicular to movie & TV lamp, avoids the user to receive the hindrance of annex on the movie & TV lamp at the in-process of operation support 3, is convenient for to the dismantlement of annex.

In some embodiments, referring to fig. 3-7, the movie lamp further includes a sliding block 4, and the sliding block 4 is connected to the push rod 2. The sliding block 4 can be a square block, the sliding block 4 can be fixed on the push rod 2 through a fastener such as a bolt, and other detachable fixed connection such as bonding, riveting or clamping is also feasible. The side of the sliding block 4 facing the front wall 11 is provided with an inclined surface matched with the inclined section 31, and the sliding block 4 is connected with the inclined section 31 in a sliding manner. Wherein the inclined surface of the slider 4 may be parallel to the inclined surface of the inclined section 31. It can be understood that the inclined surface of the sliding block 4 may be provided with a protrusion or a sliding groove, and the inclined surface of the inclined section 31 may be provided with a matching sliding groove or protrusion. Of course, in other embodiments, the sliding connection may also be a waist-shaped hole and a protrusion, and the waist-shaped hole and the fixing post are matched, so that under the condition that an external force acts on the second end of the bracket 3, the sliding block 4 slides relative to the inclined section 31 to drive the push rod 2 to move relative to the first through hole 111. The slider 4 is as push rod 2 and slope section 31 sliding connection's middle part, can reduce push rod 2's structural design complexity and cost, does benefit to the manufacturing assembly, and can make push rod 2 more smooth and easy on the in-process of slope section 31 slip. Fig. 7 shows that the surface of the slider 4 on the side facing the inclined section 31 is formed as a slope matching the inclination angle of the inclined section 31. It will be appreciated that the inclined surface of the slider 4 cooperates with the inclined section 31 when the slider 4 slides on the inclined section 31. The above arrangement makes the sliding process of the sliding block 4 on the inclined section 31 smoother.

In some embodiments, the inclined section 31 is provided with a first sliding portion 311 extending along the inclined direction of the inclined section 31, the slider 4 is provided with a second sliding portion 22 engaged with the first sliding portion 311, and the first sliding portion 311 is slidably connected with the second sliding portion 22, wherein the first sliding portion 311 and the second sliding portion 22 may be a sliding rail and a long protrusion engaged with each other, or a fixing post, a bolt, etc. and a waist-shaped hole (e.g. as shown in the drawings) engaged with each other. Under the condition that an external force acts on the second end of the bracket 3, the first connecting section 32 drives the first sliding portion 311 to slide relative to the second sliding portion 22 so as to drive the push rod 2 to move relative to the first through hole 111. The first sliding portion 311 and the second sliding portion 22 can also define the sliding direction of the sliding block 4, and the connection between the push rod 2 and the sliding block 4 can prevent the sliding block 4 from being separated from the inclined section 31.

For example, a fastening screw may be used as the second sliding portion 22, and a kidney-shaped hole may be opened in the inclined section 31 as the first sliding portion 311. The fastening screw is mounted on the slide 4, which passes through the kidney-shaped hole and is locked to the push rod 2. The sliding direction of the slider 4 is defined by the sliding connection between the fastening screw and the kidney-shaped hole.

When the first sliding part 311 and the second sliding part 22 are respectively a slide rail and a strip-shaped protrusion which are matched with each other, an avoiding section can be arranged on the sliding block 4, and the sliding block is connected with the push rod 2 by bypassing the inclined section 31 of the bracket 3 through the avoiding section, so that the reliability of connection between the sliding block 4 and the push rod 2 is ensured.

In other embodiments, as shown in fig. 6 and 7, the first sliding portion 311 may also cooperate with the push rod 2 to define the sliding direction of the slider 4 on the inclined section 31. Specifically, a waist-shaped hole may be formed in the inclined section 31 as the first sliding portion 311, one end of the push rod 2 facing the inside of the housing 1 sequentially passes through the first sliding portion 311 and the slider 4, and the slider 4 and the push rod 2 are fixed by using a bolt, in which case the slider 4 is clamped between the inclined section 31 and a head of the bolt. Of course, the person skilled in the art may also fix the sliding block 4 to the push rod 2 by other means, such as clamping, riveting, etc., which are not limited herein.

Fig. 4 and 7 show that the end of the inclined section 31 away from the second through hole 121 is provided with a support section 35, the support section 35 may be parallel to the front wall 11 of the housing 1, and an end of the first sliding portion 311 may extend onto the support section 35. It can be understood that when the second end of the bracket 3 is not subjected to an external force, the bracket 3 may support the sliding block 4 through the supporting section 35, thereby improving the stability of the bracket 3 in supporting the sliding block 4.

In other embodiments, a sliding groove may be formed on the inclined section 31 and located on a side of the inclined section 31 facing the first through hole 111, and the sliding groove extends along an inclined direction of the inclined section 31. An outwardly protruding projection may be provided at an end of the push rod 2 facing the inside of the housing 1, and the projection is slidably mounted inside the sliding groove to realize the sliding connection between the push rod 2 and the inclined section 31, which is not limited herein.

In some embodiments, referring to fig. 3 to fig. 7, as a specific implementation manner of the movie lamp provided by the embodiment of the present application, the inclined section 31 is further provided with a first guiding portion 312 disposed parallel to and spaced apart from the first sliding portion 311. The slider 4 is provided with a second guide portion 5 engaged with the first guide portion 312, and the first guide portion 312 and the second guide portion 5 are slidably connected. The first guide part 312 and the second guide part 5 may be a slide rail and a long protrusion which are correspondingly matched, or a fixing column, a bolt and the like and a waist-shaped hole (such as shown in the figure) matching structure and the like. Through mutually supporting between first guide part 312 and the second guide part 5, limited the slip direction of slider 4 on slope section 31, can guarantee that slider 4 can not rotate around the axis of push rod 2 in the gliding in-process on slope section 31 for the inclined plane of slider 4 can be stable mutually support with slope section 31, and then guarantee that slider 4 can be smooth and easy slide on slope section 31.

It should be understood that the sliding portions in the present application refer to the relative sliding connection relationship between the two, for example, the sliding fit of the screw in the kidney-shaped hole may be called the first sliding portion and the second sliding portion, respectively, but of course, the sliding fit of the corresponding protrusion and the sliding groove is also possible, and the position of the single component is not always changed at a certain point and is not considered as the sliding portion. The corresponding guide portions can be understood as such and are not described in detail herein.

A screw can be used as the second guide portion 5, and correspondingly, the slide block 4 is provided with an internal threaded hole matched with the screw. The shank of the screw projects from the internally threaded bore of the slider 4 and is located in the first guide 312. It should be noted that the width of the first guiding portion 312 matches the diameter of the screw shaft of the screw, so that, after the second guiding portion 5 passes through the first guiding portion 312, the first guiding portion 312 can limit the moving direction of the second guiding portion 5, thereby preventing the sliding block 4 from rotating around the axis of the push rod 2 during the sliding process.
