Description

Technical Field

[0001] The invention relates to the technical field of laser marking, in particular to a suspension mechanism of a laser protective cover. Background Art

[0002] In laser processing equipment, the laser protective cover is an important component to ensure the safety of the operator. It is used to isolate the laser radiation and the hazards such as debris and smoke generated during the processing. However, the design of traditional laser protective covers has obvious deficiencies in the lifting and hovering functions, especially the inability to achieve continuous hovering, which brings many inconveniences and safety hazards to the operation.

[0003] Traditional covers usually use manual pushing to achieve the lifting function. When the operator manually lifts the cover, once the cover is released, the cover will often fall rapidly due to gravity. This phenomenon not only affects the operating efficiency, but may also cause accidental damage to the equipment or the operator. In addition, the traditional cover is prone to shaking or shifting during the lifting process, further reducing the stability and safety of use. Summary of the invention

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a suspension mechanism for a laser protective cover, comprising a base and a cover body, a back plate fixed on the base, and partitions are arranged on both sides of the front of the back plate, the inner and outer areas of the partition are divided into an inner cavity and an outer cavity, a lifting block connected to the cover body slides in the outer cavity, a guide wheel is provided on the top of the back plate, a stretching piece is connected to the lifting block, and the stretching piece enters the inner cavity and is fixed after bypassing the guide wheel.

[0005] Furthermore, a protrusion is fixed on the partition, a spring is installed on the protrusion, and a concave block is arranged at a position of the lifting block corresponding to the protrusion, and the spring is used to be inserted into the concave block.

[0006] Furthermore, two bosses are formed on the convex block, and the bosses penetrate the spring sheet.

[0007] Furthermore, a hook plate is fixed on the partition in the inner cavity, and two ends of the stretching member are respectively connected to the hook plate and the lifting block.

[0008] Furthermore, the tension member is a tension spring.

[0009] Furthermore, a plurality of pulleys are installed on the inner side of the lifting block, and a guide bar slidably connected to the pulley is formed on the inner wall of the outer cavity.

[0010] Furthermore, a processing head is installed on the back side of the back plate, and a plurality of side wheels that are in contact with the inner wall of the cover body are installed on both sides of the processing head.

[0011] Furthermore, a trigger is installed on the side wall of the outer cavity of the partition, and an inclined trigger piece is connected to the trigger, and the end of the trigger piece is arc-shaped.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] The hovering mechanism of the laser protective cover manually moves the cover body upward, thereby driving the lifting block to move, and the concave block also moves with it. The concave block is separated from the spring sheet, and then under the action of the stretching member, it can help overcome the gravity of the lifting block, facilitate lifting, and support the cover body to hover. At the same time, during the movement, with the cooperation of the pulley and the side wheel, the stability of the cover movement can also be improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-6In this embodiment, a suspension mechanism of a laser protective cover includes a base 1, a back plate 2 is installed on the base 1, two groups of partitions 3 are formed on the front of the back plate 2, the inner and outer sections of the partition 3 are divided into an outer cavity and an inner cavity, an upper plate covering the inner and outer sections is fixed on the top of the back plate 2, a lifting block 7 is slidably connected in the outer cavity, a cover body 18 is fixed between the two lifting blocks 7, a handle is fixed on the outside of the cover body 18, a hook plate 8 fixed on the side wall of the inner cavity on the partition 3, a stretching member is connected between the hook plate 8 and the top of the lifting block 7, two groups of guide wheels 5 located in the inner and outer sections are installed on the top of the back plate 2, a stretching member 6 is connected to the top of the lifting block 7, and the stretching member 6 is fixed to the hook plate 8 after passing the guide wheel 5.

[0023] In the above structure, the cover body is moved by the handle, and the cover body will drive the lifting block to rise and fall in the outer cavity. The outer cavity can limit the lifting block, thereby improving the stability of the cover body's lifting and lowering. The stretching member can provide pulling force for the movement of the lifting block. At the same time, the guide wheel can also guide the movement of the stretching member to ensure that the stretching member always moves along the predetermined path, further enhancing the stability of the lifting movement. The hook plate provides a stable support point for the stretching member and can also make the cover body hover at the highest point.

[0024] A concave block 10 is fixed on the side of the lifting block 7 opposite to the partition 3, and a convex block 14 is fixed on the side of the partition 3 opposite to the concave block 10. A spring piece 12 is fixed on the convex block 14 and is inserted into the concave block 10. When the lifting block moves, the concave block will also move with it, so it will squeeze the spring piece, causing the spring piece to deform and then separate from the concave block. At this time, the cover body can move up and down autonomously. When the cover body is pushed down, the spring piece is inserted into the concave block, which can limit the concave block and prevent the cover body from moving.

[0025] Specifically, two bosses 11 are formed on the convex block 14, and the spring sheet 12 penetrates the bosses 11. The bosses serve as fixing components, and achieve stable connection by penetrating with the spring sheet.

[0026] At the same time, two pairs of pulleys 9 are installed on the side of the lifting block 7 opposite to the partition, and a guide bar is formed on the inner wall of the outer cavity, which is slidably connected to the pulley 9. A processing head 4 is installed on the back of the back plate 2, and two side wheels 13 are installed on both sides of the processing head 4, which are attached to the inner wall of the cover body 18. The sliding cooperation between the pulley and the guide bar, and the sliding cooperation between the side wheel and the cover body can further improve the stability and smoothness of the sliding of the lifting block.

[0027] The stretching member is a stretching spring, which is a soft spring connected between the hook plate 8 and the top of the lifting block 7, and bypasses the guide wheel 5. The stretching spring can improve the stable support of the lifting block, help overcome the weight of the lifting block, and make the movement smoother by cooperating with the guide wheel.

[0028] Specifically, a trigger 15 is installed on the outer cavity wall of the partition 3, and an inclined trigger sheet 16 is installed on the trigger 15. The end of the trigger sheet 16 is arc-shaped, and one end of the trigger sheet 16 can be attached to the lifting block 7. When the cover is closed, the lifting block will be driven to guide the inclined surface of the trigger sheet to the arc-shaped end, thereby squeezing the trigger sheet. During the squeezing process, the button on the trigger will be squeezed, thereby proving that the cover is sealed and the device can be powered on and run normally.

[0029] The working principle of the above embodiment is:

[0030] When the equipment is not started, the cover body pulls up the lifting block support through the tension spring to maintain the balance state, so that the cover body is in a suspended state, and the tension spring is guided by the guide wheel to ensure that the lifting block moves smoothly in the vertical direction. Before the equipment needs to be operated, the cover body is pushed down, and the lifting block moves down to drive the concave block to squeeze the spring sheet until the spring sheet is deformed and stuck into the inner side of the concave block, thereby positioning the cover body. At the same time, during the movement, the lifting block slides along the outer cavity, and the cooperation between the pulley and the guide strip, as well as the side wheel and the cover body, improves the smoothness.
