[0033] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments.

[0034] Reference Figures 1 to 3 As shown, the handle assembly of the embodiment of the utility model is made into the following embodiment.

[0035] The handle assembly includes a housing 100 and a handle 200 .

[0036] The housing 100 is provided with a mounting hole 110 which passes through in the left-right direction, and a first anti-rotation structure 120 is provided on the inner side wall of the mounting hole 110 .

[0037] The handle 200 is provided with a mounting post 210 extending in the left-right direction. The mounting post 210 can be movably provided in the mounting hole 110 . The mounting post 210 rotates around the axis of the mounting hole 110 and slides along the axial direction of the mounting hole 110 .

[0038] A second anti-rotation structure 220 is provided on the outer side wall of the mounting post 210 . The mounting post 210 slides left and right and drives the second anti-rotation structure 220 to move closer to or away from the first anti-rotation structure 120 .

[0039] When the second anti-rotation structure 220 contacts and engages with the first anti-rotation structure 120 , the first anti-rotation structure 120 limits the rotational freedom of the second anti-rotation structure 220 , thereby preventing the mounting post 210 from rotating.

[0040] When the second anti-rotation structure 220 is separated from the first anti-rotation structure 120 , the second anti-rotation structure 220 can rotate around the axis of the mounting hole 110 , thereby allowing the handle 200 to rotate.

[0041] Install the shell 100 to the outer wall of the chassis, slide the handle 200 to separate the second anti-rotation structure 220 from the first anti-rotation structure 120, so that the handle 200 can be rotated to fit the outer wall of the chassis, preventing the handle 200 from expanding outward and affecting the layout of the chassis; when the chassis needs to be moved, rotate the handle 200 to expand the handle 200 outward, and then slide the handle 200 to make the second anti-rotation structure 220 cooperate with the first anti-rotation structure 120, which can prevent the handle 200 from rotating. The transporter can hold the handle 200 to transport the chassis to prevent the handle 200 from rotating and causing the transporter's fingers or back of the hand to be squeezed by the chassis.

[0042] In some embodiments, reference Figure 2 and Figure 3 As shown, the first anti-rotation structure 120 is provided with a plurality of first anti-rotation blocks 121, which are arranged in a sequentially evenly spaced manner along the axis of the mounting hole 110. The second anti-rotation structure 220 is provided with a plurality of second anti-rotation blocks 221, which are arranged in a sequentially evenly spaced manner along the axis of the mounting post 210. The distance between each two adjacent second anti-rotation blocks 221 is equal to the distance between each two adjacent first anti-rotation blocks 121.

[0043] A plurality of first stop blocks 121 and a plurality of second stop blocks 221 are provided to cooperate with each other in a one-to-one manner, thereby jointly limiting the freedom of rotation of the handle 200 around the axis of the mounting hole 110. When the transporter unfolds the handle 200 and transports the chassis, it can ensure that the plurality of first stop blocks 121 and the plurality of second stop blocks 221 are not easily damaged under pressure, preventing the first stop structure 120 and the second stop structure 220 from being damaged and causing the fingers or back of the hand of the transporter to be squeezed by the chassis

[0044] In some embodiments, reference Figure 2 and Figure 3 As shown, each first stop block 121 extends along the circumference of the mounting hole 110 and circles around it. Each first stop block 121 forms a polygonal hole in the mounting hole 110, and the shape of each second stop block 221 matches the shape of the polygonal hole.

[0045] The first stop block 121 is used to form a polygonal hole in the mounting hole 110 to match the second stop block 221 on the periphery of the mounting column 210. The second stop block 221 can only be inserted into the polygonal hole formed by the first stop block 121 when the handle 200 is rotated to a certain specific angle, ensuring that the handle 200 can be restricted from rotating at a specific angle, so as to ensure the angle and position of the handle 200 after it is unfolded.

[0046] In some embodiments, reference Figure 2 As shown, four corners of each second anti-rotation block 221 are respectively provided with rounded corners 222 .

[0047] After the second stop block 221 is separated from the first stop block 121, the second stop block 221 can rotate in the mounting hole 110, so the corners of the second stop block 221 are set as rounded corners 222, which helps the second stop block 221 to rotate more smoothly in the mounting hole 110.

[0048] In some embodiments, reference Figure 3 As shown, the diameter of the mounting hole 110 is greater than or equal to the diameter of the circumscribed circle of each second anti-rotation block 221 .

[0049] Ensure that the second anti-rotation block 221 can rotate smoothly in the installation hole 110, ensuring that the handle 200 rotates more flexibly.

[0050] In some embodiments, reference Figure 2 and Figure 3 As shown, the handle assembly also includes an elastic member 300, which is installed in the mounting hole 110. The two ends of the elastic member 300 respectively abut the mounting column 210 and the inner wall of the mounting hole 110. The elastic force of the elastic member 300 pushes the mounting column 210 to move the second anti-rotation structure 220 toward the first anti-rotation structure 120.

[0051] After rotating the handle 200, the elastic member 300 pushes the mounting column 210 to move axially along the mounting hole 110, causing the second anti-rotation structure 220 to move toward the first anti-rotation structure 120. The second anti-rotation structure 220 can be automatically matched with the first anti-rotation structure 120 by simply adjusting the angle of the handle 200.

[0052] In some embodiments, reference Figure 2 and Figure 3 As shown, a first stop block 111 is provided on the inner wall of the mounting hole 110, and the first stop block 111 is located at the end of the mounting hole 110. A second stop block 211 is provided on the outer wall of the mounting column 210, and a space is left between the second stop block 211 and the first stop block 111. The elastic member 300 is mounted on the mounting column 210, and the elastic member 300 is located between the first stop block 111 and the second stop block 211, or the elastic member 300 abuts against the second stop block 211 and the first anti-rotation structure 120.

[0053] Using the first stop block 111 of the mounting hole 110 and the second stop block 211 of the mounting column 210 to jointly limit the elastic member 300 helps the elastic member 300 to be compactly installed in the mounting hole 110, ensuring the reliability of the elastic member 300 pushing the second anti-rotation structure 220 to move toward the first anti-rotation structure 120.

[0054] In some embodiments, reference Figure 2 As shown, the shell 100 includes a front shell 101 and a rear shell 102. The front shell 101 is detachably connected to the rear shell 102 by screws. A front semicircular groove is set on the rear side of the front shell 101, and a rear semicircular groove is set on the front side of the rear shell 102. The front semicircular groove of the front shell 101 and the rear semicircular groove of the rear shell 102 cooperate to form a mounting hole 110.

[0055] The housing 100 is configured as a split structure of a front shell 101 and a rear shell 102 to facilitate installation of the mounting post 210 of the handle 200 .

[0056] Specifically, refer to Figures 1 to 3 As shown, the handle assembly includes a housing 100 , a handle 200 and two elastic members 300 .

[0057] The shell 100 includes a front shell 101 and a rear shell 102. The front shell 101 is detachably connected to the rear shell 102 by screws. A front semicircular groove is set on the rear side of the front shell 101, and a rear semicircular groove is set on the front side of the rear shell 102. The front semicircular groove of the front shell 101 and the rear semicircular groove of the rear shell 102 cooperate to form a mounting hole 110.

[0058] Mounting hole 110 extends horizontally, with two first anti-rotation structures 120 disposed on its inner sidewall. These two first anti-rotation structures 120 are arranged in a mirror-image arrangement. Each first anti-rotation structure 120 is provided with three first anti-rotation blocks 121, which are spaced evenly apart in the horizontal direction. Each first anti-rotation block 121 extends along the circumference of mounting hole 110 and encircles it, forming a rectangular hole within mounting hole 110.

[0059] First stoppers 111 are respectively provided at the left and right ends of the mounting hole 110 , and the first stoppers 111 surround the mounting hole 110 in a circle along the circumference.

[0060] The handle 200 includes two mounting columns 210 and two second anti-rotation structures 220. The two mounting columns 210 are arranged in a mirror-symmetrical manner on the left and right. The two second anti-rotation structures 220 are arranged on the two mounting columns 210 in a one-to-one correspondence. The two second anti-rotation structures 220 are arranged in a mirror-symmetrical manner on the left and right. The two mounting columns 210 are respectively arranged on the left and right sides of the mounting hole 110.

[0061] The mounting post 210 extends in the left-right direction. The outer diameter of the mounting post 210 is smaller than the diameter of the mounting hole 110 . The mounting post 210 is movably disposed in the mounting hole 110 . The mounting post 210 can rotate and slide in the mounting hole 110 .

[0062] The mounting post 210 slides left and right and drives the second anti-rotation structure 220 to move closer to or away from the first anti-rotation structure 120 .

[0063] Each second stop structure 220 is provided with three second stop blocks 221, which are arranged in a symmetrical arrangement along the left-right direction. The distance between each two adjacent second stop blocks 221 is equal to the distance between each two adjacent first stop blocks 121, and the shape of each second stop block 221 matches the shape of the rectangular hole formed by each first stop block 121.

[0064] The four corners of each second anti-rotation block 221 are respectively provided with rounded corners 222 , and the diameter of the circumscribed circle of each second anti-rotation block 221 is smaller than the diameter of the mounting hole 110 .

[0065] The elastic member 300 is a compression spring, and the two elastic members 300 are sleeved on the outside of the two mounting posts 210 in a one-to-one correspondence.

[0066] A second stop block 211 is provided between the second anti-rotation structure 220 and the left end of the mounting column 210 on the left side. The left end of the elastic member 300 on the left side abuts against the first stop block 111, and the right end abuts against the second stop block 211. The elastic force of the elastic member 300 on the left side has a tendency to push the mounting column 210 on the left side to move to the right.

[0067] The mounting column 210 on the right side is provided with a second stop block 211 between the second anti-rotation structure 220 and the right end. The right end of the elastic member 300 on the right side abuts against the second stop block 211, and the left end abuts against the right end of the first anti-rotation structure 120. The elastic force of the elastic member 300 on the right side has a tendency to push the mounting column 210 on the right side to move to the right.

[0068] Reference Figure 4 As shown, the stage light chassis of the embodiment of the utility model is made into the following embodiments.

[0069] The stage light chassis includes the handle assembly as described in the above embodiment.

[0070] In some embodiments, reference Figure 4 As shown, the handle 200 further includes a gripping portion 230 , which is connected to the mounting post 210 and exposed outside the housing 100 .

[0071] The stage light chassis also includes a box body 400, and the shell 100 is connected to the box body 400. The box body 400 is provided with a groove 410 on the side wall where the shell 100 is located. The groove 410 is located on the rotation trajectory of the grip portion 230, so that when the handle 200 is attached to the side wall of the box body 400, the grip portion 230 is placed in the groove 410.

[0072] Because the overall size of the stage light chassis is relatively small, the weight is relatively light, and there is a need for splicing, the handle assembly of the embodiment of the present utility model can be used. Taking the mounting post 210 of the handle 200 as an example with a diameter of 8mm, the mounting post 210 of the handle 200 can actually be larger or smaller as long as the corresponding design rules are followed. Therefore, the dimensional values ​​described in the following description are typical reference values, and the parts materials and assembly processes involved are also typical processes. Actual parts are not limited to the dimensions, materials, and processes described in the description. As long as the process is achievable in the field of mechanical manufacturing, it can be considered protected by the present utility model. The following is a detailed description of the utility model.

[0073] The handle 200 is a part formed by bending a steel rod with a diameter of 8mm. The middle of the handle 200 is wrapped with a circle of anti-slip glue to form a gripping portion 230. There is a strong adhesion between the anti-slip glue and the handle 200, so that the user can hold the gripping portion 230 to drag and rotate it, making it convenient to hold and carry the stage light chassis. The diameter of the second stop block 211 on the handle 200 is 10.5mm. The size of the second stop block 221 on the left side is an 8mm×8mm square. The radius of the four rounded corners 222 is 1mm. The total length of the three second stop blocks 221 in the left and right directions including the spacing is 22mm. The length of each second stop block 221 in the left and right directions is 4mm. The distance between each two adjacent second stop blocks 211 is 5mm. Similarly, the size of the second stop structure 220 on the other side is the same. An elastic member 300 with a middle diameter of 9.2 mm and a wire diameter of 1 mm is placed between the right end of the second anti-rotation structure 220 on the right and the second stop block 211 on the right, and a second stop block 211 is provided at the left end of the second anti-rotation structure 220 on the left, and a similar elastic member 300 is also pre-placed on the second stop block 211 on the left.

[0074] The front shell 101 of the housing 100 is provided with a front semicircular groove, and the rear shell 102 is provided with a rear semicircular groove. The front shell 101 and the rear shell 102 together form a complete cylindrical hole and rectangular hole, namely the mounting hole 110. The mounting hole 110 also includes multiple first stoppers 121 on its inner wall, which can securely accommodate the mounting post 210 of the handle 200. First stoppers 111 are provided at the left and right ends of the mounting hole 110. The circular hole enclosed by the first stoppers 111 has a diameter of 8mm and a length of 2.5mm. They form a clearance fit with the mounting post 210, ensuring that the mounting post 210 can slide and rotate. Spring slots with a diameter of 11mm and a length of 18mm are provided at the left and right ends of the mounting hole 110, respectively, for accommodating the elastic member 300. The rectangular hole enclosed by each first stopper 121 measures 8mm x 8mm and is 4mm long. The mounting hole 110 has a diameter of 11mm.

[0075] Reference Figure 3As shown, when the handle 200 is folded, the elastic force of the elastic member 300 pushes the second stopper 211 on the handle 200, causing the second stopper 221 to move toward the rectangular hole formed by the first stopper 121. The six second stoppers 221 on the handle 200 are inserted into the rectangular holes formed by the first stopper 121. At this time, because the second stoppers 221 have a square cross-section, the handle 200 is restricted in its freedom and cannot rotate. This allows the handle 200 to be folded and stored on the left and right sides of the box 400. When folded, the handle 200 protrudes 10 mm from the box 400. Compared to other handle components, this height is less than the cross-sectional dimension of the handle.

[0076] Reference Figure 3 As shown, when the handle 200 of the stage light chassis needs to be expanded outward, the handle 200 can be pulled to the left 4.5mm along the axial direction of the mounting post 210 according to the expansion prompt mark on the shell 100 to overcome the pressure of the two springs. The second stop block 221 is disengaged from the rectangular hole formed by the first stop block 121 and abuts against the right side wall of the other first stop block 121, and the handle 200 can no longer be pulled to the left. At this time, the six second stop blocks 221 have all slid out of the rectangular hole into the mounting hole 110, and each second stop block 221 has slid out of the rectangular hole into the mounting hole 110. 21 is located between two adjacent first stop blocks 121. Since the diameter of the mounting hole 110 is 11 mm, which is larger than the circumscribed circle diameter of the second stop block 221, and the 8 mm cylindrical sections at both ends of the handle 200 are always in the circular hole formed by the first stop block 111, the handle 200 can rotate upward by 90°, and the second stop block 221 will be realigned with the rectangular hole formed by the first stop block 121. Under the elastic force of the elastic member 300, the second stop block 221 is reinserted to the right into the rectangular hole formed by the first stop block 121. Of course, if the handle 200 rotates less than 90°, resulting in a slight misalignment between the angle of the rectangular hole formed by the second stop block 221 and the first stop block 121 and cannot be directly inserted, the user needs to rotate the handle 200 forward and reverse to return the handle 200 to its original position. At this time, the second anti-rotation block 221 on the handle 200 is also constrained by the mounting hole 110 and cannot rotate and can only remain in the unfolded state. You can then hold the chassis handle to hold or lift the stage light chassis, or turn the lamp head downward and lift the stage light chassis in the opposite direction.

[0077] If the handle 200 needs to be folded, it is only necessary to repeat the above process, except that when rotating the handle 200, it is necessary to rotate the handle 200 downward in the opposite direction to retract it.

[0078] The core of the above description is that when the second stop block 221 on the handle 200 is aligned with the rectangular hole formed by the first stop block 121 in the mounting hole 110, the handle 200 cannot rotate. However, after moving a certain distance, the second stop block 221 is offset from the rectangular hole, allowing the second stop block 221 to enter the mounting hole 110 and restore the rotation function. This structure allows the handle 200 to switch between being rotatable and non-rotatable. Therefore, the specific shape of the handle assembly is not fixed.

[0079] The gripping portion 230 formed by the anti-slip rubber on the handle 200 is only for improving the gripping feel and is not necessary.

[0080] The main structure of the handle 200 can be a round rod bent structure, or a polygonal square rod bent structure.

[0081] The second stops 211 at both ends of the handle 200 are designed to be cylindrical only for the convenience of processing. The first stop 111 of the mounting hole 110 can also be formed into a circular hole. The second stops 211 on both sides of the handle 200 are set to polygonal cross-sections or other special-shaped cross-sections. As long as the handle 200 can be limited between the first stops 111 at both ends and can rotate around the central axis, it can be fine.

[0082] Of course, when the two ends of the handle 200 are concentric cylindrical surfaces, the cross-section of the holes formed by the first blocks 111 at both ends of the mounting hole 110 can be a polygonal structure that circumscribes the concentric circles of the handle 200, as long as it can ensure that the handle 200 can always rotate around its central axis.

[0083] The handle 200's mounting post 210 has six second stoppers 221. This ensures that, when the handle 200 is unfolded, the second stoppers 220 and the first stoppers 120 have sufficient length to fit together, ensuring the handle 200 maintains sufficient strength for transporting the stage light chassis. Furthermore, the handle 200 can be rotated even after being pulled a short distance. If necessary, the handle 200 only needs one or two second stoppers 221.

[0084] For ease of manufacturing, the two second stoppers 220 on the handle 200 are designed to be bilaterally symmetrical, allowing the handle 200 to be interchangeably installed. As long as the dimensions of the second stoppers 221 at each end of the handle 200 match the dimensions of the rectangular hole formed by the first stopper 121, and the circumscribed diameter of the second stoppers 221 is equal to or smaller than the diameter of the mounting hole 110, it is acceptable for the multiple second stoppers 221 to have different cross-sectional dimensions.

[0085] In the above description, there is a gap in the middle of the mounting columns 210 at both ends of the handle 200. In fact, a round rod or a square rod can be connected between the two, as long as the diameter of the circumscribed circle of its cross section is smaller than the diameter of the circumscribed circle of the cross section of the second stop block 221.

[0086] In the above description, the handle assemblies on both sides of the stage light chassis 400 have the same structure. In fact, the two handle assemblies can be designed with different structures as long as the basic structural principle of the present invention is met.

[0087] In the above description, there are icons and instructions on the housing 100 for pulling out and rotating the handle 200. In actual situations, this icon and instruction are only auxiliary and not necessary. Its location is not limited to the housing 100, but can also be located on the box 400, or printed on the instruction manual.

[0088] In the above description, the handle 200 is pulled to the left to unlock the rotation function. In fact, it can also be unlocked by pulling it to the right. It only requires changing the installation direction of the handle assembly.

[0089] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
