Description of the Invention: [Technical Field of the Invention] The present invention relates to a dustproof fitting for linear sliding, and more particularly to a bolt cap for linear sliding. [Prior Art] - Since the linear slide rails need to be locked on the platform, a plurality of screw reductions are provided on the strips. After the bolts are threaded, the bolts are locked with the platform and the strips are fixed. The bolt hole is still open space, so it is necessary to seal the bolt hole by the bolt cover, and (4) stop the foreign body from invading the thread, so that the slider of the secondary sliding on the rail passes through the bolt hole, so that The object is inserted into the inside of the bone block, so the setting of the bolt cover is important. However, the conventional bolt box structure is as difficult as the Taiwan Notice No. 525724. Please refer to the figure of the case - and Figure 2 discloses a side wall of the bolt cover. Edge 4 3 diameter is larger than the bolt hole of rail 1! i and the screw-pick hole are interfering with 5 °. However, the design has the following problems: h Because the machining size of the bolt hole varies greatly, if the bolt hole size is smaller than the pre-machined size, the bolt cover and the screw are caused. The interference amount of the hole is increased more than expected, so the bolt cover is prone to deformation or damage after assembly, so that the surface of the bolt cover cannot be flat with the surface of the rail, and if the bolt hole size is larger than the pre-machined size, The bolt cover 201115043 is easy to sink, so that the surface of the bolt cover cannot be flat with the surface of the rail. 2. The bolt cover does not have the function of absorbing the variation of the bolt hole size, and the bolt hole of the rail will change the size due to the use of the ambient temperature. If the temperature is high, the bolt hole size will become larger, and the screw cap will sink. However, the surface of the screw cover and the surface of the handle cannot be flush. _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The circumference of the drum portion 4 forms a projection 6 to which an upper plane 2a is attached. The upper plane 2a is covered with an elastic body 3, and the diameter of the elastic body 3 is larger than that of the body 2. Because the slot 5 is disposed such that the drum portion 4 has an elastic force to absorb the machining error of the bolt hole, but since the drum portion 4 is engaged with the upper flat surface 2 a, when the drum portion 4 is absorbed The bolt hole is deformed by machining error, and the opposite shape also evokes the original shape of the upper plane 2a. Therefore, the elastic body 3 can be easily elastically deformed to cover the upper surface 2 a, thereby absorbing the dimensional error so that the surface of the bolt cover and the surface of the rail are flush. However, such a design has the following problems: 1. The bolt cover is increased in manufacturing cost by the combination (or combination) of two components (body, elastomer). 2. The elastic body is positioned (or combined) by covering, and the elastic body is deformed by the length of 201115043 to take off the oil, the cutting fluid, etc. of the surrounding oil, and then lose the original function. SUMMARY OF THE INVENTION Based on the problems of the above-described conventional techniques, the inventors of the present invention have succeeded in research and improvement, and the invention of the following inventions can be finally achieved. Namely, the primary object of the present invention is to develop a screw cap which can absorb a screw hole, add a dimensional error of L, and is inexpensive to manufacture. In order to achieve the above object, the present invention is a linear sliding bolt cover comprising: - a disk-shaped body having a strip body formed on one side of the body - the outer side of the strip has a plurality of diameters There is a gap between the holding portion and the body to the protruding holding portion, and the holding portion is an elastically deformed structure. ▲ wherein the diameter of the bolt hole provided by the linear sliding rail is smaller than the diameter of the imaginary circle formed by the outer edge of the holding portion, and the diameter of the imaginary circle formed by the outer edge of the holding portion is larger than the diameter of the body And the outer edge of the strip does not protrude from the circumference of the body, and the diameter of the body is smaller than the diameter of the bolt hole. 201115043 ^Seek to be clear (4) The characteristics of the implementation of this day, the town to explain the progress of the car father and the practical way. The retaining part of the moon bolt cover: has the function of elastic deformation, so the processing of the hole and the hole Or the size produced by temperature changes

The bolt cover of the invention is integrally formed, simple to manufacture and low in cost. In order to further understand the features and technical aspects of the present invention, reference should be made to the description of the embodiments of the present invention and the accompanying drawings. By. [Poverty mode] See the first figure and the second figure for the 'Linear Slip 1' including: "'Rail 1 1 ' and the slider 1 3 that slides on the rail 1 and the installation 201115043 The reflow member 14 at the two ends of the slider 13 is provided with a plurality of rolling bodies (not shown) between the rail u and the slider 13 as a transmission medium of the rail 11 and the slider 13 In order to make the roll (four) reduce the cycle, the reflow member 14 provides the function of the rolling body recirculation cycle, so that the slider 3 can be infinitely on the bar: line, and linear sliding It is widely used in various processing or conveying machines. In order to fix the linear slider i to the base 2 of the machine table, a plurality of axially arranged bolt holes 1 1 1 are provided on the ? The fixing hole 3 is passed through the bolt hole! After the work, the fixing members are locked with the fixing holes 2 1 provided in the base 2, and the rails 1 1 are positioned on the base 2, and the fixing member 3 can be clearly seen from the second figure. After the locking, the bolt hole is still open, so the member is covered by the bolt hole 1 1 in the bolt hole 1 1 1 so that foreign matter cannot invade the bolt hole iii to prevent foreign matter from invading. This slider _ 13 affects the operation of the rolling elements. Furthermore, please refer to the third embodiment A'B, C and FIG. 4, which is the first embodiment of the bolt cover of the present invention.
