[0053] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0054] Reference Figure 1-5 The projector mounting frame shown is easily adjustable and includes:

[0055] There are two clamping frames 100.

[0056] The projector body 200 is clamped inside two clamping frames 100.

[0057] Two retraction devices 300 are provided and are mounted on the clamping frame 100;

[0058] The first pull rope 400 is fixed to the top of the front retracting device 300 and the clamping frame 100;

[0059] Top plate 500, the top plate 500 is fixed to the roof of the house by bolts or rivets;

[0060] Orientation device 600, which is mounted on top plate 500 and rear retractable device 300;

[0061] The second pull rope 700 is fixed to the orientation device 600 and the rear retracting device 300;

[0062] Two take-up assemblies 800 are provided and installed at the bottom of the top plate 500, for winding the first pull rope 400 and the second pull rope 700 respectively;

[0063] The counterweight 900 is provided in two sets and is fixed on the two retracting devices 300 respectively.

[0064] In use, the projector body 200 is placed inside the clamping frame 100, and then the cable winding assembly 800 is activated, so that the two cable winding assemblies 800 respectively wind around the first pull rope 400 and the second pull rope 700, causing the first pull rope 400 and the second pull rope 700 to drive the clamping frame 100 and the projector body 200 to rise. During the rise, the weight of the counterweight 900 pulls the clamping frame 100 to retract and clamp the projector body 200 in place.

[0065] When adjusting the angle of the projector body 200, the front cable take-up assembly 800 is activated, causing the first pull rope 400 to wind or unwind, which in turn causes the first pull rope 400 to pull the front clamping frame 100 up and down relative to the rear clamping frame 100, thereby adjusting the angle of the projector body 200.

[0066] The weight of the clamping frame 100 is increased by the counterweight 900. When the clamping frame 100 and the projector body 200 are raised, the clamping frame 100 is pulled to clamp and fix the projector body 200. After falling, the clamping frame 100 is released from the projector body 200, which facilitates the disassembly and installation of the projector body 200. At the same time, the clamping can be adjusted according to the size of the projector body 200.

[0067] The first pull rope 400 and the second pull rope 700 are configured to drive the clamping frame 100 and the projector body 200 to move up and down to adjust their height, and the angle of the projector body 200 is adjusted according to the difference in the line laying of the first pull rope 400 and the second pull rope 700.

[0068] The proper installation and fixation of this device is ensured by the setting of the top plate 500.

[0069] In some embodiments of this utility model, in order to properly wind the first pull rope 400 and the second pull rope 700, refer to Figure 2 As shown, the take-up assembly 800 includes:

[0070] There are two hanging plates 810, which are fixed to the bottom of the top plate 500.

[0071] The winding wheel 820 is mounted between two hanging plates 810 and is driven by a motor to rotate clockwise and counterclockwise. The motor is equipped with a self-locking structure.

[0072] The hanging plate 810 ensures the normal installation and use of the winding wheel 820, and drives the winding wheel 820 to rotate when the motor starts, so that the winding wheel 820 winds or unwinds the first pull rope 400 and the second pull rope 700 when rotating.

[0073] In some embodiments of this utility model, in order to clamp the L-shaped frame 110, refer to Figure 2 and Figure 3 As shown, the clamping frame 100 includes:

[0074] L-shaped frame 110, four L-shaped frames 110 are provided, and guide grooves 120 are provided at both ends of the L-shaped frame 110.

[0075] The receiving component 130 is provided in four parts, and connects two adjacent L-shaped frames 110.

[0076] Rubber pad 140 is bonded to the inner surface of L-shaped frame 110.

[0077] The projector body 200 is clamped by setting four L-shaped frames 110, and the distance between two adjacent L-shaped frames 110 is adjusted according to the size of the projector body 200 to increase the applicability of the L-shaped frames 110.

[0078] The cooperation between the receiving part 130 and the guide groove 120 can connect two adjacent L-shaped frames 110 together and push the four L-shaped frames 110 away to open the clamping frame 100, making it convenient for the projector body 200.

[0079] The rubber pad 140 prevents the L-shaped frame 110 from causing abrasions to the projector body 200 during clamping.

[0080] In some embodiments of this utility model, in order to ensure the connection of the L-shaped frame 110, refer to Figure 5 As shown, the receiving component 130 includes:

[0081] Guide rod 131, both ends of guide rod 131 are slidably inserted into the interior of guide groove 120;

[0082] The first spring 132 has its two ends fixedly connected to the guide rod 131 and the inner wall of the guide groove 120, respectively.

[0083] The guide rod 131 and the first spring 132 are designed to limit the maximum distance between two adjacent L-shaped frames 110, and at the same time, when the L-shaped frame 110 descends to the table, it can push the L-shaped frames 110 away from each other.

[0084] In some embodiments of this utility model, in order to drive the L-shaped frames 110 on both sides to clamp the projector body 200, refer to Figure 3 and Figure 4 As shown, the retraction device 300 includes:

[0085] Two first positioning frames 310 are provided and are respectively fixed on the outside of the two upper L-shaped frames 110;

[0086] The hinge plate 320 is provided by two hinge plates and is hinged to the first positioning frame 310;

[0087] The force-bearing frame 330 is hinged to the ends of the two hinge plates 320. The upper force-bearing frame 330 is fixedly connected to the first pull rope 400 or the second pull rope 700, and the lower force-bearing frame 330 is fixedly connected to the counterweight 900.

[0088] The first positioning frame 310 is fixedly connected to the L-shaped frame 110, and when the two L-shaped frames 110 move closer together, the L-shaped frame 110 is driven to move closer together.

[0089] The force-bearing frame 330 is designed to rise under the pull of the first pull rope 400 or the second pull rope 700, and the counterweight 900 pulls the two first positioning frames 310 closer together to clamp and fix the projector body 200.

[0090] In some embodiments of this utility model, in order to drive the upper and lower L-shaped frames 110 to clamp the projector body 200, refer to Figure 2 and Figure 3 As shown, the retraction device 300 also includes:

[0091] There are two second positioning frames 340, which are fixed on the outside of the L-shaped frame 110 and fixed on the top of the counterweight 900. The second positioning frame 340 on the front L-shaped frame 110 is fixedly connected to the first pull rope 400. The counterweight 900 is provided with a rope that passes through the upper second positioning frame 340 and falls downward.

[0092] When the L-shaped frame 110 is lifted, the counterweight 900 will pull the lower L-shaped frame 110 upward under the action of its weight, and cooperate with the upper L-shaped frame 110 to clamp and fix the projector body 200.

[0093] In some embodiments of this utility model, reference is made to Figure 2 As shown, to prevent the projector body 200 from shaking during use, the orientation device 600 includes:

[0094] Guide cylinder 610, the guide cylinder 610 is fixedly installed at the bottom of the top plate 500;

[0095] Guide rod 2 620 is fixed to the top of the force-bearing frame 330 and is fixedly connected to the second pull rope 700.

[0096] The cooperation between the guide cylinder 610 and the second guide rod 620 can limit the shaking of the projector body 200 when it is raised to the corresponding height for use, and the hinge between the second guide rod 620 and the second positioning frame 340 will not affect the angle of the projector body 200.

[0097] The working method of this utility model:

[0098] In use, the projector body 200 is placed inside the clamping frame 100, and then the motor is started, causing the motor to drive the winding wheel 820 to rotate. The winding wheel 820 winds the first pull rope 400 and the second pull rope 700, causing the first pull rope 400 and the second pull rope 700 to pull the L-shaped frame 110 upward. During the upward phase, the operator can assist by causing the force-bearing frame 330 to rotate under the pull of the first pull rope 400 or the second pull rope 700. This causes the hinge plate 320 to pull the two first positioning frames 310 closer together. At the same time, the lower counterweight 900 will also pull the lower force-bearing frame 330 downward, causing the two lower first positioning frames 310 to move closer together and clamp the projector body 200. Meanwhile, the counterweights 900 on both sides fall down and cause the two lower L-shaped frames 110 to move closer together and clamp the projector body 200.

[0099] When the two L-shaped frames 110 move closer together, they will compress the first spring 132, causing the first spring 132 to compress and store force.

[0100] When the projector body 200 is in the position above the projector body 200, the guide rod 620 will be inserted into the guide cylinder 610;

[0101] When the clamping frame 100 is lowered, the pulling force of the counterweight 900 on the retraction device 300 disappears, which releases the elastic force of the first spring 132. The first spring 132 will then push the four L-shaped frames 110 away, and then the projector body 200 can be replaced.

[0102] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
