Description

Technical Field

[0001] The utility model relates to the technical field of columns and jacks, in particular to a novel protective plug for columns and jacks. Background Art

[0002] The main function of the hydraulic cylinder joint protection plug is to prevent dust and debris from entering the hydraulic cylinder through the fluid hole before leaving the factory and installing on the user's site. Figure 1 The original installation method of the protective plug is to install the rubber ring into the groove of the protective plug, and then insert the protective plug into the joint position. At this time, the annular groove designed on the protective plug just coincides with the position of the hole on the joint. Then the U-shaped card is hammered into the joint hole to place the protective plug, which makes the installation troublesome. In addition, the user needs to take out the U-shaped card before removing the protective plug. At the same time, most U-shaped cards are directly discarded on site after use. Sometimes they are directly dismantled and discarded without being used on site, resulting in a double waste of resources and labor. For this reason, we provide a new type of protective plug for columns and jacks to solve the above problems. Utility Model Content

[0003] (1) Technical problems solved

[0004] The purpose of the utility model is to make up for the deficiencies of the prior art and to provide a new type of protective plug for a column and a jack.

[0005] (2) Technical solution

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a new type of protective plug for a column and a jack, comprising a column, a jack, and a new type of protective plug clamped on the column and the jack, wherein the column and the jack are provided with docking holes, the positions of the docking holes correspond to the liquid holes, and the docking holes are connected to the liquid holes, a U-shaped card mounting hole is provided on the inner side of the docking holes in the column and the jack, a buckle is designed on the new type of protective plug, and the buckle is rotatably clamped to the U-shaped card mounting hole, a sealing ring is provided on the new type of protective plug, and the sealing ring overlaps the inner wall of the docking hole in the column or the jack.

[0007] Furthermore, the buckle is symmetrically designed on the new protective plug.

[0008] Furthermore, the buckle is arc-shaped, and its top is a triangular protrusion or a semicircular protrusion.

[0009] Furthermore, the diameter of the front end of the buckle is smaller than the diameter of the docking hole of the connector, and the diameter of the highest position of the protrusion is larger than the diameter of the docking hole.

[0010] Furthermore, the buckle is made of metal injection molding.

[0011] (3) Beneficial effects:

[0012] Compared with the existing technology, the new protective plug for the column and jack has the following beneficial effects:

[0013] 1. The utility model adopts a symmetrical buckle design to enable quick connection after rotation, and adopts an arc-shaped structure design to enhance the locking force and prevent loosening and falling during transportation. It is made of metal injection molding to enhance its toughness and avoid breakage and leakage during transportation, thereby improving the overall low sealing effect.

[0014] 2. The utility model inserts the new protective plug into the docking hole of the connector. At this time, the top of the buckle of the new protective plug slides along the docking hole. After the top of the buckle slides into the docking hole, the new protective plug is rotated, and finally the buckle is stuck in the U-shaped card installation hole of the connector. It cannot fall off automatically without external force. At this time, the sealing ring installed on the new protective plug plays a protective role between the new protective plug and the liquid hole to prevent dust from entering.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0022] like Figure 2-5As shown, the utility model provides a technical solution: a new type of protective plug for a column and a jack, comprising a column, a jack, and a new type of protective plug 7 clamped on the column and the jack, wherein the column and the jack are provided with a docking hole 3, the position of the docking hole 3 corresponds to the liquid hole 4, and the docking hole 3 is connected to the liquid hole 4, a U-shaped card mounting hole 1 is provided on the inner side of the docking hole 3 in the column and the jack, a buckle 5 is designed on the new type of protective plug 7, and the buckle 5 is rotatably clamped with the U-shaped card mounting hole 1, a sealing ring 6 is provided on the new type of protective plug 7, and the sealing ring 6 overlaps the inner wall of the docking hole 3 in the column or the jack.

[0023] When using the above solution, first put the sealing ring 6 on the surface of the new protective plug 7, and then insert the new protective plug 7 into the docking hole 3 of the connector 2. At this time, the top of the buckle 5 of the new protective plug 7 slides along the docking hole 3. After the top of the buckle 5 slides into the docking hole 3, the new protective plug 7 is rotated, and finally the buckle 5 is stuck in the U-shaped card mounting hole 1 of the connector 2. It cannot fall off automatically without external force. At this time, the sealing ring 6 installed on the new protective plug 7 plays a protective role between the new protective plug 7 and the liquid hole 4 to prevent dust from entering.

[0024] Specifically, the buckle 5 is symmetrically designed on the new protective plug 7. The buckle 5 is arc-shaped, and its top is a triangular protrusion or a semicircular protrusion. The diameter of the front end of the buckle 5 is smaller than the diameter of the docking hole 3 of the connector 2, and the diameter of the highest position of the protrusion is larger than the diameter of the docking hole 3. The buckle 5 is made of metal injection molding.

[0025] The above solution can quickly connect after rotation by designing the buckle 5 symmetrically, and adopts an arc-shaped structure design to enhance the locking force and prevent it from loosening and falling during transportation. It is made of metal injection molding to enhance its toughness and avoid breakage and leakage during transportation, thereby improving the overall sealing effect.
