Description

Technical Field

[0001] This utility model relates to the field of projection equipment technology, and in particular to a projector. Background Technology

[0002] As a convenient display device, projectors are increasingly widely used because they can be freely moved to project onto a large screen. However, due to the different usage requirements and varying environments, projectors sometimes need to be adjusted to ensure accurate projection in different conditions. Currently, some projectors incorporate a pan-tilt mechanism, but this not only increases the cost of the projector but also makes it bulkier, affecting its portability and ease of use.

[0003] Therefore, how to meet the angle adjustment requirements and ease of use of projectors is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a projector that meets the setting requirements of convenient angle adjustment for use in various working conditions.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A projector includes a support part, a fixing part, and a limiting part. The fixing part is fixedly connected to the main body of the projector, and the support part is rotatably connected to the fixing part through the limiting part. During rotation, the position is locked by the blocking and limiting of the limiting part. The rotation angle of the support part relative to the fixing part is not less than 90 degrees.

[0007] Preferably, in the projector described above, two fixing parts are symmetrically arranged on two opposite side walls of the main body, and the supporting part spans the area between the two side walls of the main body and is rotatably connected to the two fixing parts.

[0008] Preferably, in the above-mentioned projector, the fixing part has an annular placement groove, the limiting part is a rubber ring and is disposed in the placement groove, the supporting part presses the rubber ring into the placement groove with an interference fit, and the frictional resistance between the rubber ring and the supporting part is greater than the rotational force of the supporting part relative to the fixing part under the action of gravity.

[0009] Preferably, in the projector described above, the fixing part and the supporting part engage, and the supporting part achieves position locking through the resistance between the meshing teeth.

[0010] Preferably, in the projector described above, the support is a U-shaped frame structure, and the bottom of the U-shaped frame is spaced apart from the main body.

[0011] Preferably, in the above-described projector, the rotation process of the support relative to the fixed part passes through at least the lifting position, and the support is perpendicular to the projection surface of the main body when it is in the lifting position.

[0012] Preferably, in the above-described projector, the rotation process of the support portion relative to the fixed portion further passes through at least the maximum support position, and the support portion is parallel to the projection surface when it is located at the maximum support position.

[0013] Preferably, in the projector described above, the support includes a telescopic rod, which is used to adjust the depth of the U-shaped frame.

[0014] Preferably, the projector further includes a support foot, which is fixedly disposed on the main body on the side opposite to the projection surface.

[0015] Preferably, in the projector described above, the fixing part on one side is fixedly connected to the main body by at least two fastening bolts.

[0016] As can be seen from the above technical solution, the projector provided by this utility model has a fixed part and a support part on the basis of the projector body. The fixed part is fixedly connected to the main body to serve as the mounting structure of the support part, while the mounting part is rotatably connected to the fixed part through a limiting part, so that the mounting part can realize the rotation action based on the main body. The rotatable support part can serve as an extension structure of the main body, so that the main body can produce changes in height and angle on the setting plane, thereby meeting the angle adjustment requirements under different setting planes and realizing the upright and clear projection. Moreover, for the support part, it is blocked and limited by the limiting part during the rotation process to realize position locking, thereby providing stable height and angle support for the main body and improving the versatility of the projector under different working conditions.

[0022] The core of this utility model is to disclose a projector that meets the setting requirements of various working conditions by allowing for convenient angle adjustment of the projector.

[0023] To enable those skilled in the art to better understand the present invention, embodiments of the present invention will be described below with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the invention as described in the claims. Additionally, the complete contents of the configurations shown in the following embodiments are not limited to those necessary for the solution of the invention as described in the claims.

[0024] like Figure 1-3 As shown in the figure, the projector provided in this embodiment mainly includes a support part 10, a fixing part 20, and a limiting part 30. The fixing part 20 is fixedly connected to the projector body 40, ensuring the stability of the overall structure and providing a basic installation structure for the support part 10. The support part 10 is rotatably connected to the fixing part 20 through the limiting part 30, providing a structural basis for the projector to change its shape, giving it the necessary flexibility to meet the usage requirements of different working conditions. The limiting part 30, while maintaining a stable connection between the support part 10 and the fixing part 20, provides a locking force so that when the support part 10 rotates to the required angle, it provides resistance to the support part 10, keeping it locked in its current position. This fulfills the support requirements of the body 40 and prevents displacement caused by vibration or other external forces. The rotation angle of the support part 10 relative to the fixing part 20 is not less than 90 degrees. This design not only enhances the adaptability of the projector but also allows users to adjust the angle of the projector according to the actual usage environment to obtain the best projection effect. For example, in classrooms, meeting rooms, or outdoor settings, users can easily adjust the support 10 according to the position of the wall or projection screen to ensure a clear and stable projected image. Furthermore, this design allows for rapid deployment of the projector in different settings, enabling quick identification of a suitable projection angle, whether indoors or outdoors.

[0025] Furthermore, in some embodiments of this invention, the fixing parts 20 of the projector are symmetrically arranged on two opposite side walls of the main body 40. This symmetrical layout not only enhances the aesthetic appearance of the projector but also strengthens its structural balance and stability. Correspondingly, the support part 10 spans the area between the two side walls of the main body 40 where the fixing parts 20 are located and is rotatably connected to the two fixing parts 20. This design allows the support part 10 to achieve a more stable rotation effect by using two points as the basis for rotation adjustment. In addition, the symmetrical design of the fixing parts 20 also helps to distribute the weight borne by the support part 10, reducing the pressure on a single fixing point when the projector is supported by the support part 10, thereby improving the durability and reliability of the projector.

[0026] To improve the ease of adjustment of the support part 10, in some embodiments of this utility model, the fixing part 20 is designed with an annular placement groove 210, and the limiting part 30 is a rubber ring disposed within the placement groove 210. Simultaneously, the support part 10 achieves a tight fit with the fixing part 20 by press-fitting the rubber ring into the placement groove 210. The rubber ring provides damping during the rotation of the support part 10 while maintaining the rotational fit between the support part 10 and the fixing part 20. It should be noted that the frictional resistance between the rubber ring and the support part 10 is greater than the rotational force of the support part 10 relative to the fixing part 20 under gravity, thus enabling stepless adjustment and locking of the support part 10. That is, the support part 10 can be locked by the rubber ring at any rotational position relative to the fixing part 20 when the power of manual operation is lost. This design not only provides a stable limiting function but also effectively absorbs minor deformations caused by temperature changes or slight vibrations, thereby protecting the precision components inside the projector.

[0027] In other embodiments of this invention, the fixing part 20 and the supporting part 10 achieve position locking through a meshing engagement, similar to the engagement of gears or racks, providing a simple and effective mechanical locking mechanism. The supporting part 10 achieves position locking through the resistance between the meshing teeth. This locking method is not only responsive but also easy to operate. The user only needs to gently rotate the supporting part 10, and when it reaches the desired position, the meshing teeth will automatically lock, without the need for an additional locking device. This design also allows the user to quickly adjust the position of the supporting part 10 as needed to adapt to different projection requirements.

[0028] Furthermore, in the projector provided in this embodiment of the present invention, the support part 10 adopts a U-shaped frame structure, which not only provides a stable support, but also provides space for personnel to carry the support part 10 by means of the bottom of the U-shaped frame being spaced apart from the main body 40. That is, the support part 10 can serve as a support structure when the projector needs to be adjusted in angle and height, and can also serve as a handle structure when the projector needs to be moved, thereby improving the convenience of carrying and transporting the projector.

[0029] Based on the above embodiments, the rotation process of the support part 10 relative to the fixed part 20 includes at least a lifting position. When the support part 10 is in the lifting position, it is set perpendicular to the projection surface 410 of the main body. It should be noted that the projection surface 410 is the lens mounting surface on the main body for image projection. When the support part 10 is in the lifting position and is set perpendicular to the projection surface 410, the projection surface 410 is vertically upward when the user uses the lifting and transport function of the support part 10, so as to effectively protect the lens and other components on the projection surface 410.

[0030] Furthermore, in the projector of this embodiment, the rotation process of the support part 10 relative to the fixed part 20 also passes through at least the maximum support position. When the support part 10 is in the maximum support position, it is arranged parallel to the projection surface 410, that is, the support part 10 is arranged as an extension structure of the bottom of the projection surface 410. When the support part 10 is in the maximum support position, the projection surface 410 has the maximum projection height. Correspondingly, the projection range of the projector can be adjusted in the horizontal direction and within the maximum projection height of the projection surface 410, thus having a larger adjustment range. It should be noted that, based on the above embodiment, for a structurally regular body, the angle range between the support part 10 in the lifted position and the maximum support position is 90 degrees.

[0031] Furthermore, to improve the ease of use of the support unit 10 when lifting it, and to increase the height adjustment range of the support unit 10 for the projector, in some embodiments of this utility model, the support unit 10 includes a telescopic rod. The telescopic rod is used to adjust the depth of the U-shaped frame, i.e., the overall length of the support unit 10. This telescopic rod design provides more adjustment options, allowing users to adjust the depth of the U-shaped frame according to the distance between the projector and the projection surface 410 to obtain the best projection effect. The use of the telescopic rod makes the projector more flexible, adaptable to different projection environments and positions, provides a greater height support range for the projector, and offers a more suitable lifting operation feel.

[0032] Furthermore, it should be noted that in some embodiments of this utility model, the projector also includes a support foot 50, which is fixedly disposed on the side of the main body opposite to the projection surface 410. This allows the user to directly place the projector after lifting it using the support part 10, ensuring the projector remains vertical with its projection surface 410 pointing vertically upward, thus reducing the risk of wear and tear on the projection surface 410. The additional support from the support foot 50 also ensures that the projector is more suitable for various usage environments, providing stable support whether on a hard indoor floor or on grass outdoors.

[0033] Furthermore, in some embodiments of this invention, the single-sided fixing part 20 is fixedly connected to the main body 40 by at least two fastening bolts 60. This design of the fastening bolts 60 provides a robust connection, ensuring stability and reliability between the fixing part 20 and the main body 40. The use of at least two fastening bolts 60 enhances the strength of the connection, enabling the projector to remain stable under various operating conditions, thus making the projector more durable and suitable for long-term and frequent use.
