Description

Technical Field

[0001] This utility model relates to the technical field of CNC grinding machine accessories, and in particular to a three-proof cloth accordion with an added steel plate telescopic protective device. Background Technology

[0002] The three-proof fabric accordion telescopic protective device is a flexible protective structure designed specifically for precision machinery and automated equipment. It is mainly used for the protection of key moving parts such as guide rails and lead screws, and can isolate impurities and adapt to the telescopic movement requirements of the parts.

[0003] The three-proof fabric is a flexible material that can only resist light impurities such as dust and oil. When faced with rigid impacts such as flying metal shavings or accidental collisions with tools, it is prone to tearing and damage. It cannot form an effective physical barrier like steel plates, which may lead to damage to internal equipment components. Utility Model Content

[0004] To reduce the likelihood of the above situation occurring, this application provides a three-proof cloth accordion with an added steel plate telescopic protective device.

[0005] The technical solution provided in this application for a three-proof cloth accordion with an added steel plate telescopic protective device is as follows: A three-proof fabric accordion with steel plate telescopic protective device includes a three-proof fabric folded and sewn in an accordion shape and two sliding frames. The two ends of the three-proof fabric along its length are respectively set on the two sliding frames. It also includes several steel plates and several sliding brackets. The several steel plates are slidably connected to the relatively larger steel plate in descending order of size. The several steel plates together wrap the three-proof fabric. The several sliding brackets correspond to the several steel plates and are fixedly connected to the corresponding steel plates. When the steel plate slides to the limit position towards the relatively smaller steel plate, the opposite sides of the sliding brackets on the two steel plates abut against each other.

[0006] Preferably, each of the steel plates includes a main protective portion and two side protective portions, with the two side protective portions located on both sides of the main protective portion and formed by bending the main protective portion to both sides.

[0007] Preferably, the distances from the bottom surfaces of the two side protective parts along the length of the main protective part are different, so that the main protective part is inclined.

[0008] Preferably, each of the main protective plates is provided with a brush on the side near the smaller main protective plate, and the brush abuts against the smaller main protective plate.

[0009] Preferably, the brush is arranged in a tapering shape from the higher side of the main protective part to the lower side of the main protective part along its length.

[0010] Preferably, flexible abutment blocks are provided on the side of the sliding brackets near the relatively smaller steel plate. When two sliding brackets move to abut against each other, the flexible abutment blocks abut against the side wall of the other sliding bracket.

[0011] The main technical effects of this utility model are reflected in the following aspects: 1. This utility model uses a design of "several steel plates slidingly connected from large to small and wrapping the three-proof cloth" to add a rigid protective shell to the flexible three-proof cloth, upgrading the single flexible protection to a dual protection of steel plate impact resistance and three-proof cloth impurity isolation, solving the problem that the three-proof cloth is easily damaged by metal chips and tool collisions; at the same time, the sliding bracket abuts and limits the position, which can reduce the possibility of the steel plate excessively shrinking and squeezing the three-proof cloth, ensuring its telescopic function, retaining the three-proof cloth's advantage of adapting to movement, and making up for its rigid protection shortcomings; 2. This utility model uses a steel plate structure with a main protective part and two sides bent into side protective parts to block impurities from entering from the side, reduce the contact of metal debris with the three-proof cloth or equipment parts through the gaps on the side of the steel plate, further expand the rigid protection range, and strengthen the overall protective sealing performance. 3. This utility model uses rollers to convert sliding friction into rolling friction, reducing the resistance to expansion and contraction. This ensures that the rigid protection of the steel plate does not affect the movement accuracy of the equipment, while also reducing the frictional wear between the steel plate and the three-proof cloth, extending the service life of both, and adapting to the high-speed movement requirements of precision machinery.

[0019] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail to make the technical solution of this application easier to understand and master.

[0020] This application discloses a telescopic protective device consisting of a three-proof cloth 1, a bellows-like structure, and an outer steel plate 3.

[0021] Reference Figure 2 and Figure 3 This embodiment of a three-proof fabric 1 with an accordion-style steel plate 3 telescopic protective device includes a three-proof fabric 1 folded and sewn in an accordion shape and two sliding frames 2. The two ends of the three-proof fabric 1 along its length are respectively fixedly connected to the two sliding frames 2. It also includes several steel plates 3 and several sliding brackets 4. The several steel plates 3 are slidably connected to the relatively larger steel plates 3 in descending order of size. The largest steel plate 3 is fixedly connected to the sliding plate of the frame 9. The smallest steel plate 3 is fixedly connected to a protective plate 10 on the side away from the largest steel plate 3. The protective plate 10 is fixedly connected to the end of the slide rail of the frame 9. The several steel plates 3 together wrap the three-proof fabric 1. The several sliding brackets 4 correspond to the several steel plates 3 respectively, and the several sliding brackets 4 are respectively fixedly connected to the corresponding steel plates 3. When the steel plate 3 slides to the limit position towards the relatively smaller steel plate 3, the opposite sides of the sliding brackets 4 on the two steel plates 3 abut against each other.

[0022] Reference Figure 5 and Figure 6 By using a design where "several steel plates 3 slide from large to small and wrap around the three-proof cloth 1", a rigid protective shell is added to the flexible three-proof cloth 1, upgrading the single flexible protection to a dual protection of the steel plate 3 for impact resistance and the three-proof cloth 1 for impurity isolation, solving the problem that the three-proof cloth 1 is easily damaged by metal debris and tool collisions; at the same time, the sliding bracket 4 abuts and limits the position, which can reduce the possibility of the steel plate 3 excessively shrinking and squeezing the three-proof cloth 1, ensuring its telescopic function, retaining the advantage of the three-proof cloth 1 in adapting to movement, and making up for its shortcomings in rigid protection.

[0023] Reference Figure 1 and Figure 3 Each of the steel plates 3 includes a main protective section 5 and two side protective sections 6, which are located on both sides of the main protective section 5 and are formed by bending the main protective section 5 to both sides. The structure of the steel plates 3, consisting of the main protective section 5 and the side protective sections 6, blocks impurities from entering from the sides, reduces the contact between metal debris and the protective fabric 1 or equipment components through the gaps on the sides of the steel plates 3, further expands the rigid protection range, and strengthens the overall protective sealing.

[0024] Reference Figure 1 The distances from the bottom surfaces of the two side protective sections 6 along the length of the main protective section 5 are different, which makes the main protective section 5 inclined, so that debris and impurities on the upper surface of the main protective section 5 can fall off.

[0025] Reference Figure 1 and Figure 5 Several main protective plates 10 are each provided with a brush 7 on one side near the smaller main protective plate 10. The brush 7 abuts against the smaller main protective plate 10. The brush 7 fills the gaps and cleans the surface of the relatively smaller main protective plate 10, preventing fine impurities from contacting the three-proof cloth 1. This reduces the risk of impurities adhering and causing wear or blockage of the three-proof cloth 1 or the telescopic structure. At the same time, the flexible contact of the brush 7 does not affect the telescopic movement of the steel plate 3, strengthening the protective details and solving the hidden problem of gaps in rigid protection.

[0026] Reference Figure 1 and Figure 5 The brush 7 is arranged in a tapering shape along its length, from the higher side of the main protective section 5 to the lower side. This guides impurities on the relatively small main protective plate 10, reducing the possibility of impurity accumulation and minimizing deformation of the brush 7 caused by excessive local compression, thus extending the service life of the brush 7.

[0027] Reference Figure 4 Flexible abutment blocks 8 are respectively provided on the side of several sliding supports 4 near the relatively smaller steel plate 3. When two sliding supports 4 move to abut against each other, the flexible abutment blocks 8 abut against the side wall of the other sliding support 4. The flexible abutment blocks 8 buffer the impact of contraction, reduce metal collision damage, reduce noise, and at the same time prevent the impact from causing the steel plate 3 to shift and affect the protection accuracy, indirectly protecting the internal three-proof cloth 1 and improving the overall durability and operational stability of the device.

[0028] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
