Description

Technical Field

[0001] The utility model relates to the technical field of lifting mechanisms, in particular to an optical equipment lifting platform. Background Art

[0002] Existing optical testing instruments come from different manufacturers. Large equipment will provide a proprietary control lifting platform, but its interface is single and generally cannot support other small and medium-sized equipment. It also occupies a large area and is not suitable for separate purchase. Although small test instruments are easy to carry, there are many inconveniences in actual testing due to the lack of a suitable lifting platform to adapt the height of the instrument to the screen test points of the test sample. For example, when adjusting the height, engineers need to put some other items under the test equipment. The risk is high and it is time-consuming and labor-intensive. The common lifting brackets on the market are generally designed for computer products. They can only be lifted and lowered and have certain load-bearing restrictions. Optical equipment is generally heavier, and the existing lifting brackets are not suitable. In addition, the lifting brackets currently used for testing products lack a collapse protection mechanism. When the lifting mechanism fails, it is easy to cause the support platform to instantly lose its support force and fall rapidly, which is easy to cause the optical equipment to be damaged by impact. Improvements are needed. Therefore, we propose an optical equipment lifting platform. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Embodiment 1, as Figure 1-4 As shown, the utility model provides a technical solution: an optical equipment lifting platform, including a supporting bottom plate 1, a supporting top plate 7, a supporting top plate lifting mechanism and an auxiliary lifting mechanism, the supporting top plate lifting mechanism includes a lead screw 3, a lead screw slider 5, and a motor 13 for driving the lead screw 3 to rotate, the lead screw 3 is meshed with the lead screw slider 5, the lead screw slider 5 is fixedly connected to the bottom of the supporting top plate 7 through a bracket 501, a controller 2 for controlling the motor 13 is fixedly arranged on the outside of the supporting bottom plate 1, the auxiliary lifting mechanism includes a square sleeve column 9 fixed to the top of the supporting bottom plate 1, a column 10 fixed to the bottom of the supporting top plate 7, the column 10 is embedded in the square sleeve column 9, a rack 1001 is fixedly arranged on the surface of the column 10, a baffle 12 is fixedly arranged on one side of the square sleeve column 9 by bolts, a card plate 14 is elastically installed inside the baffle 12, a rack 1401 is fixedly arranged on the side of the card plate 14 facing the column 10, and a pull rod 11 is fixedly arranged on the side of the card plate 14 away from the column 10.

[0021] In a specific embodiment of the present invention, the horizontal seat of the inverted L-shaped bracket 4 limits the top of the screw 3. The screw 3 passes through the top of the support base plate 1 and is also provided with a bearing to realize the rotation support of the screw 3. The motor 13 is composed of a reducer and a motor body. The output end of the reducer is connected to the bottom end of the screw 3. The motor body is a forward and reverse motor. The forward and reverse rotation of the forward and reverse motor is controlled by the controller 2. The electric energy of the forward and reverse motor is connected to the power supply through the power cord for power supply. When the screw 3 rotates, it meshes with the screw slider 5. Since the screw slider 5 itself cannot rotate, the screw slider 5 can only perform a lifting action, thereby driving the support top plate 7 to lift and lower. The length, width and height of the support top plate 7 are 60cm*50cm*5cm. The plate 7 is made of stainless steel to ensure its support. During the lifting of the support top plate 7, the column 10 will be driven to move in the vertical direction along the square sleeve column 9, and the rack 1 1001 will mesh with the elastically movable rack 2 1401. When the lifting of the support top plate 7 stops, the rack 2 1401 will adapt to the limit position of the rack 1 1001 to assist in supporting the corresponding column 10, thereby assisting in supporting the support top plate 7 to prevent the support top plate 7 containing the optical equipment from suddenly collapsing due to insufficient supporting force, causing damage to the optical equipment. When the height of the support top plate 7 needs to be lowered, the two connecting rods 15 need to be pulled at the same time to separate the rack 2 1401 from the rack 1 1001, and then the lead screw 3 is controlled to drive the lead screw slider 5 and the support top plate 7 to descend as a whole.

[0022] In the preferred technical solution, the clamping plate 14 passes through the square sleeve column 9 and the rack 2 1401 is meshed with the rack 1 1001. The vertical sections of the rack 1 1001 and the rack 2 1401 are both isosceles right triangles. The inclined surface of the rack 1 1001 is parallel to the inclined surface of the rack 2 1401. When the rack 1 1001 rises, the rack 1 1001 will push the rack 2 1401 to continuously move elastically. When the rack 1 1001 has a downward trend and there is no external force pulling the rack 2 1401, the rack 2 1401 will stop the rack 1 1001, thereby suppressing the descent of the rack 1 1001.

[0023] In the preferred technical solution, there are four square sleeve columns 9, which are respectively distributed at four right angles of the supporting base plate 1. The pull rods 11 of two square sleeve columns 9 on the same side are connected by a connecting rod 15. The connecting rod 15 is provided to facilitate pulling the two pull rods 11 at the same time.

[0024] In the preferred technical solution, an inverted L-shaped bracket 4 fixed to the top of the support base plate 1 is provided on the outer side of the screw 3, and a bearing is provided on the horizontal seat at the top of the inverted L-shaped bracket 4. The bearing is rotatably connected to the top of the screw 3, and a manual turning handle 6 is coaxially provided on the top of the screw 3. The manual turning handle 6 can be used to manually rotate the screw 3, thereby realizing two ways of electric and manual drive to adjust the height of the support top plate 7.

[0025] In the preferred technical solution, a limiting rod is fixedly provided on the side of the card plate 14 facing away from the column 10, and a spring is provided in the middle of the limiting rod for realizing elastic movement of the card plate 14. One end of the limiting rod is connected to the blocking cover 12, and the limiting rod cooperates with the spring to realize elastic movement of the card plate 14.

[0026] In the preferred technical solution, a cavity is opened inside the support base plate 1 , and the motor 13 is fixedly arranged inside the cavity. The cavity is provided to facilitate the storage of the motor 13 .

[0027] In summary, this embodiment adjusts the height of the support top plate 7 by electric drive and manual drive. The support top plate 7 is used to support and place the optical device, so that the mechanical lifting structure is used to replace manual labor to lift the optical device, which is convenient for testing the optical device. At the same time, a lifting safety auxiliary mechanism is designed based on the lifting structure. During the hovering process of the support top plate 7, the self-locking effect of rack 1 1001 and rack 2 1401 is used to achieve auxiliary support of the support top plate 7, thereby ensuring the safety and stability of the optical device during lifting.
