Abstract
The utility model relates to a protection device for a guide bar, comprising: the spring and a dustproof sleeve coated outside the spring; the spring is sleeved on the periphery of the guide rod, one end of the spring is fixed on the top plate, and the other end of the spring is fixed at the joint of the guide cylinder and the guide rod; the dustproof sleeve is a cylindrical telescopic dustproof sleeve, and two ends of the dustproof sleeve are respectively connected with the joint of the top plate, the guide cylinder and the guide rod through seal sleeves; when the guide rod reciprocates, the spring and the dust boot are stretched or compressed together. The device solves the problems that a gap exists between the guide rod and the guide cylinder, and after long-term reciprocating motion, dust or foreign matters easily fall into the gap, so that the guide rod is blocked and the guide rod is not smooth to run; compared with the existing dustproof sleeve, the dustproof sleeve body does not need to be provided with air holes, the guide rod and the guide cylinder can be effectively protected, and the service life of the dustproof sleeve is prolonged.
Description
Technical Field
The utility model relates to an auxiliary device of mechanical equipment, in particular to a protective device of a guide rod.
Background
In mechanical equipment, it is often required that a part is free to move back and forth or up and down, but the part is required to move linearly on a plane, i.e. not to move obliquely, and a guide device is required, generally a guide cylinder is manufactured to guide the insertion of a guide rod. The guide rod and the guide cylinder are not integrally formed, a certain gap exists between the guide rod and the guide cylinder, dust or other foreign matters can fall into the gap in the long-term reciprocating operation process, the friction resistance between the guide rod and the guide cylinder is increased, the operation is not smooth, the clamping is performed or even the deformation is caused, and the manual cleaning effect is unsatisfactory, time-consuming and labor-consuming.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of providing a protective device of a guide rod aiming at the defects in the prior art.
The technical scheme adopted by the utility model for solving the technical problems is as follows: a guard for a guide bar comprising:
the spring and a dustproof sleeve coated outside the spring; the spring is sleeved on the periphery of the guide rod, one end of the spring is fixed on the top plate, and the other end of the spring is fixed at the joint of the guide cylinder and the guide rod;
the dustproof sleeve is a cylindrical telescopic dustproof sleeve, and two ends of the dustproof sleeve are respectively connected with the joint of the top plate, the guide cylinder and the guide rod through seal sleeves;
when the guide rod reciprocates, the spring and the dust boot are stretched or compressed together.
According to the scheme, the periphery of the spring is covered with a layer of transparent soft film which is used for dust prevention and can synchronously move along with the spring.
According to the scheme, the dustproof sleeve is a transparent plastic dustproof sleeve made of PVC resin.
According to the scheme, the dustproof sleeve is a Polydimethylsiloxane (PDMS) dustproof sleeve.
According to the scheme, the dustproof cover is a breathable and waterproof non-woven fabric dustproof cover.
According to the scheme, the dustproof sleeve body is a corrugated pipe-shaped sleeve body consisting of a plurality of circular rings.
According to the scheme, the inner diameter of the sealing sleeve at the joint of the dustproof sleeve and the guide cylinder and the guide rod is smaller than the outer diameter of the guide cylinder.
The utility model has the following beneficial effects:
the device solves the problems that a gap exists between the guide rod and the guide cylinder, and after long-term reciprocating motion, dust or foreign matters easily fall into the gap, so that the guide rod is blocked and the guide rod is not smooth to run; compared with the existing dustproof sleeve, the dustproof sleeve body does not need to be provided with air holes, the guide rod and the guide cylinder can be effectively protected, and the service life of the dustproof sleeve is prolonged.
Drawings
The utility model will be further described with reference to the accompanying drawings and examples, in which:
FIG. 1 is a schematic structural diagram of an embodiment of the present invention;
FIG. 2 is a schematic structural diagram of an embodiment of the present invention;
in the figure: 1-guide rod, 2-spring, 3-dustproof cover, 4-guide cylinder, 5-top plate.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
As shown in fig. 1, a guard device for a guide bar includes:
a spring 2 and a dustproof cover 3 coated on the spring; the spring is sleeved on the periphery of the guide rod 1, one end of the spring is fixed on the top plate 5, and the other end of the spring is fixed at the joint of the guide cylinder 4 and the guide rod;
as shown in fig. 2, the dust-proof cover 3 is a cylindrical telescopic dust-proof cover made of air-permeable and water-impermeable non-woven fabric, and two ends of the dust-proof cover are respectively connected with the joint of the top plate, the guide cylinder and the guide rod through seal sleeves;
when the guide rod reciprocates, the spring and the dust boot are stretched or compressed together.
Furthermore, the periphery of the spring is covered with a layer of transparent soft film which is used for dust prevention and can synchronously move along with the spring.
Furthermore, the dustproof cover is preferably made of high-elasticity elastomer materials in an integrated forming mode, and the dustproof cover is good in compactness, so that the sealing performance and the compression frequency of the dustproof cover are improved. In this embodiment, the dust-proof cover may also be a transparent plastic dust-proof cover made of Polydimethylsiloxane (PDMS).
Further, in this embodiment, the dust-proof sleeve body is a corrugated pipe-shaped sleeve body formed by a plurality of circular rings.
It will be understood that modifications and variations can be made by persons skilled in the art in light of the above teachings and all such modifications and variations are intended to be included within the scope of the utility model as defined in the appended claims.
