In a specific embodiment, the preset first direction is a direction perpendicular to the plane where the base is located.

[0006] In a specific embodiment, it also includes a connecting member fixedly connected to the connecting plate, and the first force arm is rotatably connected to the connecting plate through the connecting member.

[0007] In a specific embodiment, the connecting member includes a first connecting portion and a second connecting portion; the first connecting portion is fixedly connected to the connecting plate; the second connecting portion is folded toward the pressing portion relative to the first connecting portion so that the first force arm rotates in the plane where the second connecting portion is located, and one end of the first force arm is rotatably connected to the second connecting portion.

[0008] In a specific embodiment, a line formed by the connection position of the second force arm and the first force arm and the connection position of the second force arm and the pressing head is at an angle to the first direction, so that the second force arm can adjust the direction of force under the pressure from the pressing part.

[0009] The pressing head includes a transmission assembly and a connector; one end of the transmission assembly is connected to the second lever arm, and the other end is connected to the connector, wherein the connector is used to contact the gasket. In practical applications, the specific structure of the end of the connector that contacts the external part can also be set according to actual needs, and the connector can be provided with a structure that is simply engaged with the external part, so that the alignment between the connector and the external part is more accurate.

[0010] In a specific embodiment, the transmission assembly includes a buffer structure, a transmission rod, a first set of rods and a second set of rods; one end of the first set of rods is movably connected to the second force arm in a preset first direction, and the other end is movably nested with the transmission rod; one end of the second set of rods is movably nested with the transmission rod, and the other end is fixedly connected with a connecting head; the buffer structure is sleeved on the exposed part of the transmission rod relative to the first set of rods and the second set of rods.

[0011] In a specific embodiment, the buffer structure is a spring that is sleeved and surrounds the exposed portion of the transmission rod relative to the first set of rods and the second set of rods. The spring is arranged so that during the pressing process, the spring can provide a buffer force to the downward pressure generated by the first force arm, so that the force applied by the first force arm is not a rigid force, thereby preventing the user from applying excessive force when operating the first force arm and damaging parts or equipment.

[0012] In actual application, the transmission rod is a screw, the first set of rods and the second set of rods are a screw sleeve, the screw and the screw sleeve cooperate with each other, and during the pressing process of the pressing mechanism, the screw performs piston motion in the screw sleeve, so that the pressing head can flexibly adjust the pressure applied to the external parts in the groove.

[0013] In a specific embodiment, a protruding outer ring is provided at the edge of one end of the transmission rod extending into the second rod, and the diameter of the protruding outer ring is larger than the opening diameter of the end of the second rod connected to the transmission rod, and smaller than the diameter of the internal space of the second rod.

[0014] By setting a protruding outer ring, the diameter of the protruding outer ring on the side where the transmission rod is connected to the second set of rods is between the opening diameter of the second set of rods and the inner diameter of the second set of rods, so that when the pressing mechanism is lifted compared to the groove during the pressing process, the connection between the transmission rod and the second set of rods can be engaged by the protruding outer ring, and the transmission rod will not slip out of the second set of rods.

[0015] In a specific embodiment, it also includes a limiting part, which is fixedly connected to the base or the connecting plate. The limiting part is provided with a limiting hole in a preset first direction. The pressing head passes through the limiting hole and is movably connected to the second force arm. The limiting part is used to limit the movement direction of the pressing head.

[0016] In a specific embodiment, the limiting part can be connected to the connecting member and connected to the first connecting part of the connecting member. An auxiliary part is also extended at the limiting hole, so that the first set of rods and the transmission rod can be less affected by shaking in the limiting hole. When the user operates the pressing mechanism to press, the first set of rods will move in the limiting hole. At this time, the auxiliary part extended at the limiting hole can guide and stabilize the first set of rods, helping the transmission assembly to be stably aligned with the groove.

[0017] In a specific embodiment, a blocking member is further included, and the transmission rod enters one end of the first sleeve rod and passes through the blocking member and the buffer structure in sequence; the outer diameter of the blocking member is larger than the diameter of the limiting hole. During a use process, the blocking member can be a bolt sleeved on the transmission rod and the spring. Since the outer diameter of the bolt is larger than the diameter of the limiting hole, when the user pulls the pressing device up a certain distance, the bolt will form a blockage at the limiting hole, so that the sleeve rod and the transmission rod are restricted to the lower position of the connecting member and will not be pulled out of the limiting hole by the user, thereby enhancing stability during use.

[0018] In a specific embodiment, the sum of the lengths of the movable spaces in the first set of rods and the second set of rods for accommodating the transmission rod is less than or equal to the length of the transmission rod, so that the transmission rod will not slip off between the two sets of rods.

[0019] In a specific embodiment, an auxiliary groove connected to the groove is also provided on the base, and the auxiliary groove is used to assist in placing and removing external parts.

[0020] In a specific embodiment, a wire groove connected to the groove is further provided on the base, and at least one end of the wire groove is connected to an edge of one end of the base.

[0021] In a specific embodiment, the shape of the groove matches the shape of the external part, and a positioning piece is provided in the groove, and the positioning piece is used to be embedded in the external part to position the external part.

[0022] In an actual application process, the user first lifts the pressing mechanism by pressing the first lever arm, places a gasket at the connector of the pressing head, and first engages the external part with the gasket. At this time, the external part contacts the gasket, but does not fit tightly with the gasket. After installing the gasket and the external part, the user presses down the first lever arm, presses the first lever arm to further transmit the force to the second lever arm, and the second lever arm transmits the force to the transmission rod and the connector of the transmission assembly, and converts it into a force applied toward the groove along the first direction. During the pressing process, the pressing mechanism drives the external part and the gasket to move into the groove. Since the groove matches the external part, and a positioning member for positioning the external part is provided in the groove, the external part can be adapted to the groove, and the force transmitted by the pressing head to the groove can be accurately transmitted to the gasket and the external part, so that the gasket fits tightly with the external part through pressing. After the pressing is completed, the user can lift the pressing mechanism and remove the external part with the gasket installed from the groove through the auxiliary groove.

[0023] It should be noted that the present application does not limit the specific steps in the pressing process. As long as the gasket can be pressed onto the external part and the gasket and the external part can be firmly installed, it is also possible to first place the external part and the gasket in the groove and then operate the pressing mechanism to press and install the gasket.

[0024] In a specific embodiment, when a plurality of pressing mechanisms are arranged side by side on a base, in addition to pressing each pressing mechanism individually, the first force arms of the plurality of pressing mechanisms can be combined by providing a handle joint, so that the user can apply pressure once to the handle joint manually or mechanically to drive the plurality of pressing mechanisms to perform pressing operations at the same time, thereby further improving the installation efficiency of the gasket.

[0025] Beneficial effects: The present application provides a gasket pressing device with a simple structure, and can realize the processing of multiple parts at the same time by setting up multiple pressing mechanisms at the same time. The user can adjust the direction of the force applied to the pressing mechanism by cooperating with the first force arm and the second force arm in the pressing part, and quickly exert force and install the parts and gaskets. At the same time, the transmission component can evenly apply pressure to the gasket and external parts while transmitting force, so that the installation of the gasket and external parts can be more accurate and stable.

The specific details of the pressing mechanism 3 are as shown in FIG. Figure 5 In a specific embodiment, the preset first direction is a direction perpendicular to the plane where the base 1 is located, such as Figure 3 Shown in the middle direction A.

[0044] In a specific embodiment, it also includes a connecting member 33 fixedly connected to the connecting plate 2 , and the first force arm 311 is rotatably connected to the connecting plate 2 through the connecting member 33 .

[0045] In a specific embodiment, the connecting member 33 includes a first connecting portion 331 and a second connecting portion 332. The first connecting portion 331 is fixedly connected to the connecting plate 2. The second connecting portion 332 is folded toward the pressing portion 31 relative to the first connecting portion 331, so that the first force arm 311 rotates in the plane where the second connecting portion 332 is located, and one end of the first force arm 311 is rotatably connected to the second connecting portion 332.

[0046] In a specific embodiment, a line formed by a connection position between the second force arm 312 and the first force arm 311 and a connection position between the second force arm 312 and the pressing head 32 forms an angle with the first direction.

[0047] The pressing head 32 includes a transmission assembly and a connector 326. One end of the transmission assembly is connected to the second lever arm 312, and the other end is connected to the connector 326. The connector 326 is used to contact the gasket. In practical applications, the specific structure of the end of the connector 326 that contacts the external part 4 can also be set according to actual needs. The connector 326 can be provided with a structure that is simply engaged with the external part 4, so that the alignment between the connector 326 and the external part 4 is more accurate.

[0048] In a specific embodiment, the transmission assembly includes a buffer structure 324, a transmission rod 323, a first set of rods 321 and a second set of rods 322. One end of the first set of rods 321 is movably connected to the second lever arm 312 in a preset first direction, and the other end is movably nested with the transmission rod 323. One end of the second set of rods 322 is movably nested with the transmission rod 323, and the other end is fixedly connected with a connector 326. The buffer structure 324 is sleeved on the exposed portion of the transmission rod 323 relative to the first set of rods 321 and the second set of rods 322.

[0049] In a specific embodiment, the buffer structure 324 is a spring that is sleeved and surrounds the exposed portion of the transmission rod 323 relative to the first set rod 321 and the second set rod 322. The spring is arranged so that during the pressing process, the spring can provide a buffer force for the downward pressure generated by the first force arm 311, so that the force applied by the first force arm 311 is not a rigid force, thereby preventing the user from applying excessive force when operating the first force arm 311 and damaging parts or equipment.

[0050] In actual application, the transmission rod 323 is a screw, the first set of rods 321 and the second set of rods 322 are a threaded sleeve, the screw and the threaded sleeve cooperate with each other, and during the pressing process of the pressing mechanism 3, the screw performs piston motion in the threaded sleeve, so that the pressing head 32 can flexibly adjust the pressure applied to the external part 4 in the groove 11.

[0051] In a specific embodiment, a protruding outer ring is provided at the edge of one end of the transmission rod 323 extending into the second sleeve rod 322 , and the diameter of the protruding outer ring is larger than the opening diameter of the end where the second sleeve rod 322 and the transmission rod 323 are connected, and smaller than the diameter of the internal space of the second sleeve rod 322 .

[0052] By setting a protruding outer ring, the diameter of the protruding outer ring on the side where the transmission rod 323 is connected with the second set rod 322 is between the opening diameter of the second set rod 322 and the inner diameter of the second set rod 322, so that when the pressing mechanism 3 is lifted compared to the groove 11 during the pressing process, the connection between the transmission rod 323 and the second set rod 322 can be clamped by the protruding outer ring, and the transmission rod 323 will not slip out of the second set rod 322.

[0053] In a specific embodiment, it also includes a limiting portion 333, which is fixedly connected to the base 1 or the connecting plate 2. The limiting portion 333 is provided with a limiting hole 334 in a preset first direction. The pressing head 32 passes through the limiting hole 334 and is movably connected to the second force arm 312. The limiting portion 333 is used to limit the movement direction of the pressing head 32.

[0054] In a specific embodiment, the limiting portion 333 is connected to the connecting member 33, specifically, vertically connected to the first connecting portion 331 of the connecting member 33, such as Figure 4 An auxiliary piece is also extended at the position of the limiting hole 334, so that the first set rod 321 and the transmission rod 323 are less affected by shaking in the limiting hole 334. When the user operates the pressing mechanism 3 to press, the first set rod 321 moves in the limiting hole 334. At this time, the auxiliary piece extended at the position of the limiting hole 334 can guide and stabilize the first set rod 321, and help the transmission assembly to be stably aligned with the groove 11.

[0055] In a specific embodiment, a blocking member 325 is further included. The transmission rod 323 enters one end of the first sleeve rod 321 and passes through the blocking member 325 and the buffer structure 324 in sequence; the outer diameter of the blocking member 325 is larger than the diameter of the limiting hole 334. During use, the blocking member 325 can be a bolt sleeved on the transmission rod 323 and the spring. Since the outer diameter of the bolt is larger than the diameter of the limiting hole 334, when the user pulls the pressing device up a certain distance, the bolt will form a blockage at the limiting hole 334, so that the sleeve rod and the transmission rod 323 are restricted to the lower position of the connecting member 33 and will not be pulled out of the limiting hole 334 by the user, thereby enhancing the stability during use.

[0056] In a specific embodiment, the sum of the lengths of the movable spaces in the first rod set 321 and the second rod set 322 for accommodating the transmission rod 323 is less than or equal to the length of the transmission rod 323 , so that the transmission rod 323 will not slip off between the two rod sets.

[0057] In a specific embodiment, the base 1 is further provided with an auxiliary groove 12 connected to the groove 11, and the auxiliary groove 12 is used to assist in the insertion and removal of the external part 4. In actual application, after pressing, the user can remove the processed external part 4 in the groove 11 through the auxiliary groove 12.

[0058] In a specific embodiment, the base 1 is further provided with a wire groove 13 connected to the groove 11, and at least one end of the wire groove 13 is connected to an edge of one end of the base 1. In practical applications, some external parts 4 are connected to data lines or connecting lines. By placing the data lines or connecting lines in the wire groove 13, the position of the external parts 4 in the groove 11 can be further stabilized, so that the placement of the external parts 4 on the base 1 is more standard and reduces confusion.

[0059] In a specific embodiment, the shape of the groove 11 matches the shape of the external part 4 , and a positioning member 111 is disposed in the groove 11 . The positioning member 111 is used to be embedded in the external part 4 to position the external part 4 .

[0060] In an actual application process, the user first lifts the pressing mechanism 3 by pressing the first lever arm 311, places a gasket at the connector 326 of the pressing head 32, and first engages the external part 4 with the gasket. At this time, although the external part 4 is in contact with the gasket, it is not tightly fitted with the gasket. After installing the gasket and the external part 4, the user presses down the first lever arm 311 to further transmit the force to the second lever arm 312. The second lever arm 312 transmits the force to the transmission rod 323 and the connector 326 of the transmission assembly, and converts it into a force applied toward the groove 11 along the first direction. In the process of pressing, the pressing mechanism 3 drives the external part 4 and the gasket to move into the groove 11. Since the groove 11 cooperates with the external part 4, and the groove 11 is provided with a positioning member 111 for positioning the external part 4, the external part 4 can be adapted to the groove 11, and the force transmitted by the pressing head 32 to the groove 11 can be accurately transmitted to the gasket and the external part 4, so that the gasket is tightly fitted with the external part 4 through pressing. After the pressing is completed, the user can lift the pressing mechanism 3 and take out the external part 4 with the gasket installed from the groove 11 through the auxiliary groove 12 .

[0061] It should be noted that the present application does not limit the specific steps in the pressing process. As long as the gasket can be pressed onto the external part 4 and the gasket and the external part 4 can be firmly installed, it is also possible to first place the external part 4 and the gasket in the groove 11 and then operate the pressing mechanism 3 to press and install the gasket.

[0062] In a specific embodiment, when a plurality of pressing mechanisms 3 are arranged side by side on a base 1, in addition to pressing each pressing mechanism 3 individually, the pressing handles of the plurality of pressing mechanisms 3 can be combined by providing a handle joint part, so that the user can apply pressure once to the handle joint part manually or mechanically to drive the plurality of pressing mechanisms 3 to perform pressing operations at the same time, thereby further improving the installation efficiency of the gasket.

[0063] This embodiment provides a gasket pressing device with a simple structure, and can realize the processing of multiple parts at the same time by setting up multiple pressing mechanisms at the same time. The user can adjust the direction of the force applied to the pressing mechanism by the cooperation of the first force arm and the second force arm in the pressing part, and quickly apply force to install the parts and gaskets. At the same time, the transmission component can evenly apply pressure to the gasket and external parts while transmitting the force, so that the installation of the gasket and external parts can be more accurate and stable.
