The vertical fixed clamps 401 are connected to the lower inner wall of the 3D printer frame, and a sliding channel is formed between a pair of vertical fixed clamps 401 for the vertical sliding plate 402 to slide.

The vertical sliding plate 402 is slidably arranged in the sliding channel formed between a pair of vertical fixed clamping plates 401, and is adapted to the sliding channel. When the 3D printer rack generates vibration or external force in the vertical direction, it can drive the vertical The sliding plate 402 moves relative to the vertical fixed clamping plate 401 , and dissipates energy from the external force through sliding friction, so as to buffer and divide the vibration or external force.

As shown in FIGS. 4-5 , the vertical shock absorber 4 further includes multiple sets of auxiliary buffer grooves 405 and buffer sliders 406 corresponding to the auxiliary buffer grooves 405 .

Among them, multiple sets of auxiliary buffer grooves 405 are respectively symmetrically opened on the two surfaces of the vertical slide plate 402 close to the pair of vertical fixed clamping plates 401, and the upper and lower inner walls of the auxiliary buffer grooves 405 are respectively connected with upper buffer rods for shock absorption and protection. 407 and the lower buffer rod 408, under normal conditions, the buffer slider 406 is at the central axis of the auxiliary buffer groove 405, and there is a certain predetermined distance between the upper buffer rod 407, the lower buffer rod 408 and the buffer slider 406, and the upper buffer rod 407 and the lower buffer rod 408 are all elastic materials, which can cooperate with the relative sliding of the upper shock-absorbing spring 403 and the lower shock-absorbing spring 404 and the vertical slide plate 402 and the vertical fixed clamp 401, and perform buffering when the buffer slider 406 slides. pressure.

The buffer slider 406 is slidably arranged in the auxiliary buffer groove 405, and the ends of the plurality of buffer sliders 406 away from the vertical slider 402 are all fixedly connected with the vertical fixed clamp 401, and the buffer slider 406 is used to cooperate with the vertical fixed clamp 401 To move, the buffer slider 406 is excavated with the first shock absorbing hole that is all adapted to the upper buffer rod 407 and the lower buffer rod 408, and the buffer slider 406 is connected to the upper buffer rod 407 and the lower buffer rod 408 through the first shock absorbing hole. Swipe to connect.

At the same time, the diameter of the first damping hole is slightly smaller than the diameters of the upper buffer rod 407 and the lower buffer rod 408. Due to the elastic material of the upper buffer rod 407 and the lower buffer rod 408, the vertically fixed clamping plate 401 is driven by a large external force or vibration. Relative movement occurs with the vertical slide plate 402, and when the buffer slider 406 is driven to move, when the buffer slider 406 moves to a predetermined value, it can slide relative to the surface of the upper buffer rod 407 or the lower buffer rod 408 through the first shock absorbing hole, so that The upper buffer rod 407 or the lower buffer rod 408 stores energy in the process of being squeezed by the buffer slider 406. When the buffer slider 406 breaks away from the surface of the upper buffer rod 407 or the lower buffer rod 408, the upper buffer rod 407 and the lower buffer rod The extruded part of the surface of 408 releases energy, so reciprocating, can buffer the external force, and cooperate with related components such as the upper damping spring 403 and the lower damping spring 404 to improve the buffering and damping efficiency.

Simultaneously, upper damping spring 409, lower damping spring 410, upper damping spring 403 and lower damping spring 404 form step damping and buffering, and vibration and external force impact within the predetermined range and vibration and external force impact beyond the predetermined range can be performed. Effective shock absorption and buffering, when the vibration and external impact are within the predetermined range, the 3D printer frame and the protective base body 1 will slide relative to each other, driving a pair of vertical fixed clamps 401 and vertical slide 402 to move relative to each other. At the same time, the upper damping spring 403 and the lower damping spring 404 are driven to be deformed. At this time, the buffer slider 406 cooperates in the auxiliary buffer groove 405, and the sliding at this time is only between the upper buffer rod 407 and the lower buffer rod 408. , can absorb and buffer shocks and external shocks within a predetermined range.

When the vibration and external force shock exceed the predetermined range, the buffer slider 406 continues to move until the buffer slider 406 contacts with the lower end of the upper buffer rod 407 or the upper end of the lower buffer rod 408.

When the upper buffer spring 409 or the lower buffer spring 410 is deformed to a predetermined degree, it will drive the buffer slider 406 to perform a reverse movement of recovery and be squeezed at the same time. The surface of the upper buffer rod 407 or the lower buffer rod 408 restores deformation, cooperates with the upper shock absorber spring 403 and the lower shock absorber spring 404 between energy storage and energy discharge for shock absorption and buffering, while the upper buffer spring 409 and the lower buffer spring 410, the upper damping spring 403 and the lower damping spring 404 form a cascade of damping and buffering, which can more effectively dampen and buffer vibrations and external force shocks inside and outside the predetermined range, especially vibrations and external force shocks outside the predetermined range Divide the pressure to protect the accuracy and quality of the printed 3D model.
