The armor type shield is mainly used for covering the surface of a telescopic structure of a machine tool and providing protection. Traditional armour formula guard shield includes the scale of setting externally, perpendicular to scale setting inside backup pad and the flexible material of the backup pad that connects corresponding at each level scale. The supporting plates or the scales of the armor type shield are pulled or pushed by a telescopic structure of a machine tool, in the process, the flexible materials are matched with corresponding bending or stretching of the supporting plates at all levels to stretch, the limitation of the range of the moving stroke between the scales is realized, and the phenomenon that the scales are loosened or exposed out of the internal structure of the shield due to excessive stretching is avoided. However, the flexible material has insufficient mechanical strength and is easily broken at its bent portion to cause the entire shield structure to fail.

For the life who increases the guard shield, the utility model provides a replace brand-new armor formula guard shield of above-mentioned structure.

Referring to fig. 2, the present invention provides an armor type shield, which has an inner support 41 attached to the inward bent side wall of each scale 4. Or the inner bracket can be arranged to be bent inwards from the inner side of the scale to support the scale. The inner support may be made of metal, and it is generally preferable to use a metal sheet having higher strength and larger thickness than the scale 4, for example, a stainless steel sheet. The side walls of the inner brackets 41 of two adjacent scales 4 can be connected through an elastic connecting device with elasticity to realize linkage.

Referring to fig. 1, in one implementation, the elastic connection device includes:

a first connecting member 1 having one end provided with a first connecting structure 11 and the other end connected to a side wall of an inner support of the armor shield;

a second connector 2, one end of which is provided with a second connecting structure 21 and the other end of which is connected with the side wall of another adjacent inner support of the armor shield;

the second connecting structure 21 is fixedly connected with the first connecting structure 11.

In the elastic connection device, when the first connection member and the second connection member are connected, the ends of the first connection member 1 and the second connection member 2, which are used for connecting the inner bracket 41 of the armor shield, are deviated from each other. The initial distance between the two ends of the elastic connecting device is set to exceed the limit distance stretched between two adjacent scales 4 in the armor shield under the condition that the elastic connecting device is not influenced by external force, so that the elastic driving force for restoring the initial distance can be provided for the inner support.

When the elastic connecting device is installed between the inner supports 41 of the armor type shield, the far ends of the first connecting piece and the second connecting piece, which deviate from each other, are respectively provided with a screw hole shown in fig. 1 as a first support connecting point 12 and a second support connecting point 22, and the first connecting piece and the second connecting piece are respectively fixed between the side walls of the inner supports 41 connected with the adjacent two-stage scales 4 in the armor type shield through screws 42, bolts or clamping pieces, puncture structures and the like. Because the distance between the inner support is less than the initial distance of elastic connection device, consequently, the distal end that first connecting piece and second connecting piece deviate from each other all do not the lateral wall of the adjacent inner support of butt, provide the effort of maintaining at initial condition to inner support and the scale that connects.

In order to avoid the connection failure of the first and second bracket connection points, the pressing piece 43 may be padded between the screw 42 and the first bracket connection point 12 or/and the second bracket connection point 22. The screw 42 presses the pressing plate 43, and the pressing plate plane uniformly applies the abutting force to the two first bracket connecting points 12 and the two second bracket connecting points 22 at the far ends of the first connecting piece 1 and the second connecting piece 2, so that the pressing plate is stably and reliably fixed on the side wall of the inner bracket.

From this, elastic connection device can be respectively stable assembly between the inner support 41 of the scale 4 of each level of armour formula guard shield, realizes the linkage at each level of inner support. Under elastic connection device's effect, the utility model discloses an armor formula guard shield is by the extending structure drive of lathe and compress or stretch the distance between the scale. At this time, the relative displacement between the scales 4 drives the inner bracket 41 at the bending side to drive the elastic connecting devices connected between the inner brackets to compress or stretch. Since the elastic attachment means is already in a slightly compressed state in the initial assembled state, further compression or stretching between the scales does not exceed the range of stresses which they can withstand. The elastic connecting device is elastically deformed under the action of the internal support, and transmits strain force to the internal supports at the front and rear stages to drive the internal supports to have potential energy for recovering the initial state. In case the drive power of lathe extending structure is relieved, the utility model discloses a scale at different levels can receive its inside elastic connection device's drive and the recovery of linkage to initial condition in the armor formula guard shield.

For current flexible material's passive atress, the utility model discloses an elastic connection device can initiatively order about the synchronous linkage of scale at different levels of armour formula guard shield. Because the utility model discloses well elastic connection device's mechanical strength and whole metal shrapnel thickness all are greater than its inside support of connecting to be greater than outside scale, form the structure of strong outer weak in the interior, the utility model discloses an its internal connection system of armor formula guard shield can not become invalid because of the wearing and tearing of scale. Therefore, the utility model discloses can effectively guarantee the complete difficult inefficacy fracture of guard shield overall structure, further prolong the life of whole guard shield structure.

Referring to fig. 2, in the elastic connection device, the first connection structure 11 may be configured as a plug-in slot, and the second connection structure 21 may be correspondingly configured as a protrusion matching the size of the plug-in slot. The two are inserted to realize self-locking, and the installation is convenient.

Considering the stress condition between the inverted connection structures, the insertion groove can be further arranged to be parallel to the end edge of the first connecting piece 1; the protrusions are arranged to protrude from the edge of the end part of the second connecting piece 2 and are parallel to the insertion groove. So as to avoid the relative rotation of the plugging structure to cause the mutual separation of the structures and the loss of the connection function.

In a more specific implementation manner, the insertion groove is arranged in the middle of the end of the first connecting piece 1, and the protrusion protrudes out of the middle of the edge of the end of the second connecting piece 2, both of which are in a form symmetrical to the long axis of the integral elastic connecting device. Therefore, the instability caused by single-side insertion can be further avoided, and the two insertion structures are prevented from being separated from failure due to relative rotation at the single-side insertion position. Under the state that the protrusions are inserted into the insertion grooves, the front ends of the first connecting pieces 1 and the front ends of the second connecting pieces 2 are overlapped and abutted with each other, the rear ends of the first connecting pieces are far away from each other and abutted with and fixed to two adjacent side walls in the inner support of the armor type shield respectively, and linkage between all levels of the inner support is achieved.

In order to ensure that the elastic connecting device has enough elasticity to support the internal support to automatically restore to the initial spacing at each level, in an implementation mode, the utility model further comprises a bending part which deviates from the second connecting piece 2 and is arranged at the position, close to the splicing groove, in the first connecting piece 1; and a bending part departing from the first connecting piece 1 is arranged at a position, close to the bulge, in the second connecting piece 2. The connecting piece of the rear end of buckling deviates from each other, and the connecting piece of the front end of buckling is mutually abutted, inserted and fixed. The bending part is used as a fulcrum. When the armor type shield stretches towards two sides, the distance between the connecting pieces at the bent rear end is increased, but the stretching limit size of the shield cannot reach the initial distance between the two ends under the action that the elastic connecting device is not subjected to external force all the time, so that the two connecting pieces still keep a compressed state. And under the state that two connecting pieces are compressed, the position of buckling is as the fulcrum, because the effect of this angle of buckling and the fixed action of buckling front end grafting structure to two connecting piece tip, 1 front end of first connecting piece with 2 front ends of second connecting piece overlap each other all the time and mutual butt. The splicing structure is practically not subjected to the external force applied by the shield structure in the whole process of compressing or stretching the armor type shield. That is to say, the utility model discloses mounting tie point 13, 23 is not atress throughout the whole process of armour formula guard extension or compression between two connecting pieces all the time. Therefore, the utility model discloses an inside support especially sets up the elastic connection device between them, all keeps the surplus of deformation in the overall process of this armour formula guard shield extension or shrink, and the overall process at extension or compression is atress very little, therefore, its life of extension that can be further.

However, under comparatively preferred mode, for avoiding between two connecting pieces mounting tie point 13, 23 relative rotation and lead to grafting structure pine to take off and influence elastic connection device stable, the utility model discloses still can further first connecting structure 11 extremely between buckling second connecting structure 21 extremely be provided with mounting 3 between buckling, through the front end of two connecting pieces is connected to mounting 3, the restriction first connecting piece 1 with relative rotation between the second connecting piece 2 to guarantee that the grafting structure can not rotatory pine take off, guarantee that elastic connection device can not become invalid to the effort of inner support.

In a simple implementation manner, the fixing member 3 may be provided in the form of two or more screws, buckles, piercing structures, etc. arranged in parallel to the insertion groove. It is only responsible for connecting two connecting pieces, avoids relative rotation between the connecting piece and need not bear the extrusion or the tensile strength of whole armour formula guard shield flexible process. Therefore, the utility model discloses the connecting piece structure that adopts also can effectively protect this mounting 3, avoids its atress and the pine takes off inefficacy.

Further, as shown in fig. 3 and 4, the elastic connection means are respectively arranged symmetrically along a line perpendicular to the scales at the two ends of each pair of adjacent internal supports of the armor shield. With particular reference to fig. 3, the bracket attachment points 12, 22 of each resilient attachment means are all arranged at equal distances from the opposite scales, and are likewise arranged at equal distances from the respective inner bracket ends. Like this, the mutual end to end overlap joint of outside scale, and its inside elastic connection device aligns along the dotted line of fig. 3, because elastic connection device mechanical strength is higher than outside scale, the scale can be deformed by slight inside tractive owing to inside elastic connection device for more inseparable laminating between the scale of at different levels realizes sealing between the scale, and the scale through mutual inseparable butt forms first order waterproof construction. Therefore, the utility model provides an armour formula guard shield is at tensile or shrink removal in-process, and the scale on its surface can be close a inline by inside support and elastic connection device tractive all the time, and it is inseparable to laminate each other between the scale, links between at different levels, only has the friction along the moving direction between the scale in the removal process, and the surface laminating degree is high, has preliminary water-proof effects. Therefore, the utility model discloses can solve between the armor formula guard shield that current flexible material connects the problem of patting each other, perk.

In order to ensure that the scales of the armor type shield move along the straight line, the present invention can further set a wear-resistant block 52 and/or a pulley 53 at the end of the inner support in a manner shown in fig. 4 and 7, or further form a slot 51 between the wear-resistant block 52 and/or the pulley 53 and the scales.

The grinding blocks 52 and/or the pulleys 53 move along guides of the machine tool on which the armour shield is mounted, stretching the armour shield or compressing it. And the clamping groove 51 can further guide the clamping of the guide structure to prevent the armor type shield from being bent in the compression process.

In one implementation, the armor shield of the present invention may be placed on the machine tool 6 structure shown in fig. 5 in the manner shown in fig. 6. The clamping groove 51 is clamped with a sheet metal structure on the side of a guide device of the machine tool to guide the armor type shield and seal the machine tool, and the wear-resistant block 52 and/or the pulley 53 move along the guide device of the telescopic structure of the machine tool so as to ensure that the armor type shield is stretched or compressed in a linear mode all the time, lateral oblique acting force cannot be generated on an internal structure, and the internal structure is stable and does not rotate relatively.

Taking the structures shown in fig. 4 and 5 as examples, the upper and lower ends of each stage of inner supports of the armor-type shield are respectively provided with wear-resistant sliding blocks 52 and pulleys 53 at intervals, and equal gaps are reserved between the wear-resistant sliding blocks and the pulleys 53 and the inner surfaces of the scales to form clamping grooves 51. The armored shield is mounted on a machine tool 6 shown in fig. 5. The wear-resistant block 52 and/or the pulley 53 at the lower end of the wear-resistant block is abutted to the upper end face of the lower rail 61, the clamping groove 51 at the lower end of the wear-resistant block is clamped to the upper end face of a lower sheet metal baffle 64 arranged on the outer side of the lower rail 61 in parallel to the scales, the wear-resistant block 52 and/or the pulley 53 at the upper end of the wear-resistant block is abutted to the upper end face of the inner wall of the upper sheet metal auxiliary rail 63, the upper ends of the scales are shielded and sealed by the upper sheet metal baffle 62 on the outer side, and the clamping groove 51 at the upper end of the wear-. Therefore, the whole armor shield can be pushed by the machine table casting 7 to move synchronously with the slide block 8 arranged on the lower rail 61, and can be stretched or compressed along the lower rail 61 along the left-right direction of the figure, so that the internal structure of the machine tool is sealed.

On this basis, for the convenience of installing on the lathe 6 that 5 is shown, in the armor formula guard shield of the utility model, the inside support that the scale that outside and innermost corresponds still links respectively has the flange that figure 9 or figure 10 are shown. The machine tool telescopic structure drives the flange 11 of the movable end, while the flange 32 of the fixed end remains stationary fixed to the fixed structure of the machine tool. Therefore, the utility model discloses an armour formula guard shield along the synchronous and corresponding tensile or compression of this extending structure's of accompanying of lathe extending structure's track direction to provide spacing to the scale at tensile in-process, guarantee that the scale can not outwards overturn. The inside of this armour formula guard shield still is provided with the spacing area of connecting all levels scale. In order to fix the two ends of the limit belt 9, the flange 11 may be further provided with pressing sheets, and the pressing sheets 4 abut against the sidewall surface of the flange 11, so as to limit the two ends of the limit belt 9 therebetween, respectively, thereby fixing the limit belt 9.

Wherein the pressing plate 4 can be correspondingly fixed on the inner bracket or the flange 11 through screws. The screws penetrate the inner bracket, the pressing sheet, the flange structure between the pressing sheet and the limiting belt 9 at the same time, so that the inner bracket, the pressing sheet and the flange structure are connected into a whole.

The machine tool is complicated in structure, some telescopic structures need to provide protection from multiple directions, and therefore, the scales are also provided with a plurality of bends in the telescopic direction according to the requirements of the telescopic structures in a manner similar to that of fig. 9. In order to guarantee the synchronous operation between each bending structure, the utility model discloses still can further be provided with one or more at each bending position of each scale along the direction that is on a parallel with the scale motion spacing area 9. Each limiting belt 9 is stretched along the stretching direction or the compressing direction of the armor type shield respectively, so that all the scales at all levels and all the longer scales can be synchronously linked, the scales are integrally stretched or contracted along the uniform direction, and the internal structure of the armor type shield is further stabilized.

The limiting belt 9 refers to a structure between the scale and the waterproof fabric of the armor type shield shown in fig. 8. The outside of the limiting belt is sequentially lapped by a plurality of layers of scale 4 structures to form protection on the telescopic structure in the machine tool. The end of each scale can be bent inwards or connected with an internal bracket which extends inwards and is vertical to the inner wall surface of the scale. The bent inner sides of the inner support or scale form an inner support 41. The utility model discloses a spacing 9 of taking sets up on this inner support, installs between the inner support of armour formula guard shield, presses close to the lateral wall of inner support is fixed, spacing area is connected respectively the inboard tip of inner support and the outside tip of adjacent inner support, with zigzag connection between each scale 4 of armour formula guard shield will scale 4 inside tractive of armour formula guard shield prevents its outside upset.

In the connection mode shown in fig. 8, the scale on the right side of fig. 8 is arranged on the innermost side of the outer surface of the integral armor type shield, the left side of the scale is provided with an inner bracket which is perpendicular to the inner surface of the scale and is bent inwards by nearly 90 degrees, and the left side of the outer surface of the scale is lapped with another layer of scale. Each layer of scales is arranged in the same direction and is sequentially overlapped outside the outer surfaces of the scales on the right side. The scales are equal or at least close to each other in distance, the scales are parallel to each other, and the scales are drawn together or drawn away from each other by the movement of the telescopic structure in the random bed 6. The limiting belt 9 is connected with the inner side and the outer side of the inner support 41 of each scale, Z-shaped connection is formed among the scales, and the scales are limited to turn outwards.

In fig. 8, the scale on the right side is disposed on the innermost side of the armor cover, and the scale on the left side is disposed on the outermost side. For the clearance realization water seal between each scale in the armour formula guard shield of dwindling as far as possible, the utility model discloses in will spacing area 9 is connected to the outside of the inside support 41 of its one deck scale from the inboard of the inside support 41 of each layer scale according to the scale from inside to outside order in order and forms, then is connected to the outside of the inside support 41 of one deck scale again from the inboard of the inside support 41 of this layer scale, so reciprocal, forms the spacing to each layer scale. Therefore, in the process that the armor type shield is gradually stretched to the limit position by being driven by a machine tool, the limit belt 9 is gradually stretched and straightened along with the armor type shield, the inner side of the inner support 41 of the scale is obliquely and outwards pulled, the scale 4 connected with the inner support 41 is driven to turn inwards, and the inner wall of the scale is tightly attached to or abutted against the outer surface of one layer of the scale.

Taking one layer of scale as an example, the tensile force of the scale is analyzed in the manner of fig. 8. The inner side of the corresponding inner bracket 41 of the spacing belt 9 connected with any middle layer of scale generates an inclined outward pulling force F1 through the pulling of the outer layer of scale, and the outer side of the corresponding inner bracket 41 generates an inclined inward pulling force F2 through the pulling of the inner layer of scale. Both pulling forces have an inward component which acts on the scale 4 such that the outer side of the scale 4 tends to rotate inwards. When the scale rotates inward, the inner wall surface of the scale abuts against the outer wall surface of the inner layer of the scale and is limited. At this moment, because of spacing connection of 9 and slightly warp between the scale adjacent, its outside compresses tightly each other, from this, can restrict the shake between the scale, restricts the scale and outwards overturns, effectively reduces and beats each other and the noise that produces between the scale. The scale is closely attached to each other, so that the sealing effect is good, the first-stage waterproof effect is reinforced, and the sealing waterproof effect can be improved along with the increase of the stretching degree of the scale.

In order to assemble the limiting belts 9, the inner brackets 41 of the scales can be respectively provided with a limiting belt fixing structure. The fixing structure can be provided as a through hole for the spacing belt 9 to pass through. The limiting belt 9 passes through the through hole, can be attached to the side wall of the internal support, the limiting belt 9 is stretched to the inner side of the internal support 41 from the outer side of the internal support 41 close to the scale, so that the limiting belt 9 on each layer of scale is connected to the inner side of the internal support 41 of the inner layer of scale adjacent to the internal support from the outer side of the internal support 41 close to the scale, and is connected to the outer side of the internal support 41 of the outer layer of scale adjacent to the internal support 41 from the inner side of the internal support 41 far away from the scale.

In other implementations, the strap 9 may be assembled by a strap retainer fixture 91 as shown in FIG. 8. The fixing part 91 of the position limiting band can be in the form of a patch or a pressing sheet, and is attached to and abutted against the inner bracket 41, so that the position limiting band 9 is attached to the side wall of the inner bracket 41 in the width direction and is pressed and fixed. Because the butt restriction of the inside and outside both sides of spacing area mounting 91, spacing area 9 follows the outside of spacing area mounting 91 is connected to the inboard of the inside support 41 of one deck scale in, follows the inboard of spacing area mounting 91 is connected to the outside of the inside support 41 of one deck scale outside, forms the zigzag and connects, provides the pulling force of inside upset to the scale, stabilizes the connection between each scale.

Outside the waterproof sealing effect of above-mentioned structure, the utility model discloses still connect waterproof surface fabric between the inboard of inner support for waterproof surface fabric covers the inboard of armour formula guard shield. Therefore, the problem of water leakage caused by gaps formed in the moving process of the external scales can be avoided. This waterproof fabric seals the elastic connection structure between inner support and the support outside the waterproof fabric in the scale, and guard shield inner structure is smooth, can reduce the interference to lathe inner structure to provide better waterproof performance.

The utility model discloses a grafting structure of self-locking formula utilizes this structural connection to each have sufficient elastic connecting piece, realizes the connection and the linkage to the inner support of scale.
