Using the above scheme, by the way that the first dirt-proof boot for closing the first opening is arranged on bearing block ontology and is used for Second dirt-proof boot of the second opening of closing, when bearing block is shelved or temporarily when not in use, using the first dirt-proof boot and second Dirt-proof boot is sealed against, and can prevent extraneous dust from entering inside bearing block, and then will not occur bearing Caton when in use The case where.

Preferably, the material of first dirt-proof boot and the second dirt-proof boot is rubber.

Using the above scheme, rubber has certain elasticity and firmness is high and non-aging, is well suited as this Dust-proof cover material.

Preferably, first dirt-proof boot was towards an end face last week on the floor to several inserted blocks are equipped with, and in institute It states and offers several jacks for being matched with inserted block on bottom plate.

Using the above scheme, when installing the first dirt-proof boot, several inserted blocks be can be inserted into corresponding jack, to realize installation Stable purpose.

Preferably, first dirt-proof boot side mirror image is provided with a pair of first shifting block.

Using the above scheme, by the setting of the first shifting block, it can facilitate and extract the first dirt-proof boot from bearing block ontology.

Preferably, the first non-slip texture is provided on the side of first shifting block.

Using the above scheme, the setting of the first non-slip texture can increase the friction when extracing the first dirt-proof boot between hand Power, to play the role of conveniently winning.

Preferably, second dirt-proof boot includes the first bulge loop for being tightly attached to the bearing block body outer wall, is tightly attached to axis Hold the second bulge loop of inner body wall.

Using the above scheme, when installation, the first bulge loop is tightly attached to the outer wall of bearing block ontology, and the second bulge loop is tightly attached to bearing The inner wall of seat ontology, can play good sealing effect and firmness is good.

Preferably, mirror settings have a pair of second shifting block on the second dirt-proof boot lateral surface.

Using the above scheme, the setting of the second shifting block can facilitate and extract the second dirt-proof boot from bearing block ontology.

Preferably, the second non-slip texture is provided on second shifting block.

Using the above scheme, the setting of the second non-slip texture can increase the friction when extracing the second dirt-proof boot between hand Power, to play the role of conveniently winning.

Preferably, there are two mounting holes, two mounting holes to be located at the two of the bearing block ontology for setting on the bottom plate Side.

Using the above scheme, the setting of two mounting holes, which can facilitate, is installed on entire bearing block elsewhere.

Preferably, the installation hole shape is waist-shaped hole.

Using the above scheme, when installation, the position of some parts, which is extremely difficult to position between ideal position or part, to be needed It adjusts, the setting of waist-shaped hole is conveniently detachable.

In conclusion the utility model has the following beneficial effects:

By the way that the first dirt-proof boot for closing the first opening is arranged on bearing block ontology and is used to close the second opening The second dirt-proof boot, when bearing block shelve or temporarily when not in use, using the first dirt-proof boot and the second dirt-proof boot its is close Envelope can prevent extraneous dust from entering inside bearing block, and then will not occur the case where bearing Caton when in use.

Specific embodiment

The utility model is described in further detail below in conjunction with attached drawing.

As shown in Figure 1 and Figure 2, a kind of bearing block, including bottom plate 1 and the bearing block ontology 2 being fixedly installed on bottom plate 1.? Two sides of bearing block ontology 2 and being located on bottom plate 1 are opened up there are two mounting hole 12, and two 12 shapes of mounting hole are waist-shaped hole, For entire bearing block to be fixedly installed in elsewhere.

There are the first opening 22 and the second opening 21 on bearing block ontology 2, is arranged with the first dirt-proof boot at the first opening 22 3, the second dirt-proof boot 4 is arranged at the second opening 21, the first dirt-proof boot 3 and the second dirt-proof boot 4 is cylindric and material is equal For rubber.

As shown in Figure 1, Figure 3, the first dirt-proof boot 3 is connected at equal intervals towards circumferential direction at the outside of one end of bottom plate 1 Several inserted blocks 31, and circumferentially about offer what several interted for inserted block 31 on bottom plate 1 and positioned at bearing block ontology 2 Jack 11.

Mirror image is connected with a pair of first shifting block 32 on the side of the first dirt-proof boot 3, dust-proof in order to dismantle first Set 3, is connected with the first non-slip texture 33, on the side of two the first shifting blocks 32 to play frictional force between increase and hand Effect.

As shown in Figure 1, Figure 4, Figure 5, it is connected with the first bulge loop 41 at the outer edge of the second dirt-proof boot 4, can be used for tight It is affixed on the lateral surface of bearing block ontology 2；The second bulge loop 42, the second bulge loop are also connected on one end face of the second dirt-proof boot 4 42 and first bulge loop 41 be respectively positioned on the ipsilateral of the second dirt-proof boot 4 and the radical length of the second bulge loop 42 less than the first bulge loop 41 Radical length, the second bulge loop 42 can be used for being close to the inner wall of the second opening 21 in bearing block ontology 2.

Same mirror image is connected with a pair of second shifting block 43 on the lateral wall of the second dirt-proof boot 4, and at two second groups It is provided with the second non-slip texture 44 on block 43, extracts the second dirt-proof boot 4 from bearing block ontology 2 to facilitate.

The course of work:
