Abstract

A pressing device is provided, including: a main body, including a chamber; a pushing assembly, including a retractable mechanism movably inserted within the chamber, a first pushing board connected with the retractable mechanism and a restricting member embedded within the chamber and blocking the retractable mechanism from moving out of the chamber; a hydraulic mechanism, including a tube body which is connected with the main body and communicated with the chamber, a driving rod movably inserted within the tube body and a piston driven by the driving rod, the piston being configured to drive fluid to flow in or out of the chamber. Another pressing device is further provided, differing from the pressing device described above in that: the main body further including a channel, a wall of the chamber including at least one recession which is communicated with the channel.

First claim

What is claimed is:

1. A pressing device, including:
a main body, including a chamber;
a pushing assembly, including a retractable mechanism movably inserted within the chamber, a first pushing board connected with the retractable mechanism and a restricting member, the restricting member being embedded within an inner surface of the chamber, the restricting member blocking the retractable mechanism from moving out of the chamber in a moving path of the retractable mechanism;
a hydraulic mechanism, including a tube body which is connected with the main body and communicated with the chamber, a driving rod movably inserted within the tube body and a piston driven by the driving rod, the piston being configured to drive fluid to flow in or out of the chamber;
wherein the pushing assembly further includes a stabilizing member received in the chamber, and the stabilizing member is abutted between an outer circumferential surface of the retractable mechanism and the inner surface of the chamber.

2. The pressing device of claim 1 , wherein the hydraulic mechanism further includes an elastic member disposed in the tube body and between the piston and the main body.

3. The pressing device of claim 1 , wherein the retractable mechanism includes at least two sleeve members, one of the at least two sleeve members is fluid-tightly connected with the chamber, and each of the at least two sleeve members are relatively movable and fluid-tightly sleeved with each other co-axially.

4. The pressing device of claim 1 , wherein the pushing assembly further includes a fastener detachably connected with the first pushing board and connected to the retractable mechanism.

5. The pressing device of claim 1 , wherein in an axial direction of the chamber, the chamber includes a small diameter section and a large diameter section which are communicated with each other, a stepped portion is disposed at an intersection of the small diameter section and the large diameter section, the large diameter section is open at a side of the main body to define an opening, the retractable mechanism is pillar-shaped and disposed through the opening and inserted into the chamber, the retractable mechanism is projectable out of the opening, and the stabilizing member is received in the large diameter section and blockable by the stepped portion in the axial direction.

6. A pressing device, including:
a main body, including a chamber and a channel, a wall of the chamber including at least one recession which is communicated with the channel;
a pushing assembly, including a retractable mechanism movably inserted within the chamber and a first pushing board connected with the retractable mechanism;
a hydraulic mechanism, including a tube body which is connected with the main body and communicated with the channel, a driving rod movably inserted within the tube body and a piston driven by the driving rod, the piston being configured to drive fluid to flow, via the channel, into or out of the chamber;
wherein the tube body is disposed lateral to the chamber, the retractable mechanism is movable to be within the chamber and at least partially overlapable with the channel in a radial direction of the chamber.

7. The pressing device of claim 6 , wherein the retractable mechanism is movable to at least partially cover an end opening of the channel.

8. The pressing device of claim 6 , wherein the main body further includes a connection portion extending toward a direction away from the first pushing board, the connection portion is connected with a second pushing board opposite to the first pushing board, and the recession is at least partially recessed within the connection portion.

9. The pressing device of claim 8 , wherein the chamber at least partially extends within the connection portion.

10. The pressing device of claim 7 , wherein the main body further includes a connection portion extending toward a direction away from, the connection portion is connected with a second pushing board opposite to the first pushing board, and the recession is at least partially recessed within the connection portion; the chamber at least partially extends within the connection portion; the hydraulic mechanism further includes an elastic member disposed in the tube body and between the piston and the main body; the retractable mechanism includes at least two sleeve members, one of the at least two sleeve members is fluid-tightly connected with the chamber, and each of the at least two sleeve members are relatively movable and fluid-tightly sleeved with each other co-axially; the pushing assembly further includes a fastener detachably connected with the first pushing board and connected to the retractable mechanism; the pushing assembly further includes a restricting member engaged within an inner surface of the chamber, the restricting member blocking the retractable mechanism from moving out of the chamber in a moving path of the retractable mechanism; the tube body includes a head portion connected with the driving rod and a body portion detachably connected with and between the head portion and the main body; the first pushing board and the second pushing board each have at least one through hole configured for assembling of a plate; the pushing assembly further includes a stabilizing member received in the chamber, the stabilizing member is abutted between an outer circumferential surface of the retractable mechanism and the inner surface of the chamber; in an axial direction of the chamber, the chamber includes a small diameter section and a large diameter section which are communicated with each other, a stepped portion is disposed at an intersection of the small diameter section and the large diameter section, the large diameter section is open at a side of the main body to define an opening, the retractable mechanism is pillar-shaped and disposed through the opening and inserted into the chamber, the retractable mechanism is projectable out of the opening, and the stabilizing member is received in the large diameter section and blockable by the stepped portion in the axial direction; the stabilizing member is a ring detachably sleeved around the retractable mechanism; the stabilizing member is made of metal.
