Description

Technical Field

[0001] The present invention relates to the field of transmission equipment, and in particular to an extrusion swing arm and a driving system. Background Art

[0002] In the sealing application of doors and windows, especially sliding doors and windows, since sliding doors and windows will move along the length direction of the outer frame, the common sealing method of sliding doors and windows is to set a sealing strip on the inner side of the door leaf / window leaf, and the door leaf / window leaf presses the sealing strip against the outer frame, that is, there is an interference fit between the sealing strip and the outer frame.

[0003] Therefore, when the door / window sash is pushed or pulled, the sealing strip will rub against the outer frame, so the following problems arise: first, the sealing strip will rub against the outer frame, resulting in an unsmooth pushing and pulling movement of the door / window sash; second, long-term friction of the sealing strip will cause wear of the sealing strip and the outer frame, resulting in a decrease in sealing performance. Summary of the invention

[0004] In order to overcome at least one of the defects of the prior art described above, the present invention provides an extrusion swing arm, which can be applied to the lateral pressure of doors and windows, but is not limited thereto.

[0005] The technical solution adopted by the present invention to solve the problem is:

[0006] Toggle section;

[0007] An extrusion part, one end of which is used to be connected to the side pressure piece, and the other end is arranged on the toggle part. Under the action of the toggle part, the extrusion part applies pressure to the side pressure piece for compression sealing with the side pressure receptor; and / or under the action of the toggle part, the pressure applied by the extrusion part to the side pressure piece for compression sealing with the side pressure receptor is released.

[0008] When the side pressure piece needs to perform side pressure, the present invention uses the toggle part to toggle the extrusion part, and the extrusion part squeezes and pushes the side pressure piece (such as the side pressure door and window) to complete the side pressure of the side pressure piece, that is, the side pressure piece and the side pressure receptor (such as the door and window installation frame) are squeezed and sealed. When the side pressure piece needs to move, the squeezing and pushing of the side pressure piece by the extrusion part is released, and the squeezing and sealing between the side pressure piece and the side pressure receptor are immediately released. Therefore, there is no friction between the side pressure piece and the side pressure receptor, thereby avoiding friction between the side pressure piece and the side pressure receptor when the side pressure piece moves.

[0009] Furthermore, the extrusion portion includes a connecting seat and a rotating handle, the connecting seat is used to apply force to the side pressure member under the action of the rotating handle, one end of the rotating handle is rotatably disposed on the connecting seat, and the other end is disposed on the toggle portion.

[0010] Therefore, the extrusion part utilizes the rotation of the rotating handle to push the side pressure part, and thereby completes the side pressure of the side pressure part. The rotating structure makes it easier for the toggle part to toggle the extrusion part, thereby improving the smoothness of the toggle and improving the user experience.

[0011] Furthermore, a pushing column is provided on the rotating handle for moving the moving part.

[0012] Thus, the toggle member toggles the push column, thereby realizing the rotation of the rotating handle, preventing frequent contact and friction between the rotating handle and the toggle member, and avoiding excessive damage to the rotating handle.

[0013] Furthermore, the toggle part is a toggle block, the toggle block is provided with a toggle groove, and the push column is slidably disposed in the toggle groove.

[0014] Therefore, the toggle groove of the toggle block forms a toggle limit for the push column, ensuring that when the toggle block toggle the push column, the toggle block and the push column are connected to avoid separation.

[0015] Furthermore, the rotating handle includes a rotating body, a handle body, a spring and a blocking piece;

[0016] The rotating body includes a fixed seat and a rotating seat, the fixed seat is arranged on the connecting seat, the rotating seat is respectively plugged into the fixed seat and connected to the handle body, the pushing column is arranged on the handle body, the spring is arranged on the fixed seat and sleeved on the rotating seat, and the baffle is arranged at one end of the rotating seat and the fixed seat, so as to limit the spring on the rotating seat.

[0017] Therefore, the plug-in connection between the fixed seat and the rotating seat facilitates the rotation of the rotating handle, and the rotating handle pushes the side pressure piece and the side pressure receptor to perform side pressure sealing through rotation.

[0018] Furthermore, the toggle groove comprises a low-position toggle groove and a high-position toggle groove, a step is formed between the high-position toggle groove and the low-position toggle groove, and a transition slope is arranged at the connection between the high-position toggle groove and the low-position toggle groove.

[0019] Therefore, the low-position toggle groove and the high-position toggle groove are used to change the relative positions of the rotating handle and the connecting seat. When the rotating handle is located in the high-position toggle groove, the rotation of the rotating handle can realize the squeezing and pushing of the side pressure piece, while when it is in the low-position toggle groove, it is in a non-side pressure state of the side pressure piece. In the non-side pressure state, the rotating handle is received in the low-position toggle groove. If the side pressure piece moves at this time, the collision of the rotating handle with other components can be effectively prevented.

[0020] Furthermore, part of the side wall of the toggle slot protrudes outwards and forms a receiving position for receiving an end of the handle body away from the rotating body.

[0021] Thus, the receiving position receives the end of the handle body away from the rotating body, effectively preventing the end of the handle body away from the rotating body from being exposed, causing the handle body to collide with other components when the side pressure piece moves.

[0022] Furthermore, a pressing column is provided on the handle body so as to roll relative to the pushing column, and the pressing column is located at an end of the handle body away from the rotating body.

[0023] Therefore, the side pressure piece is pushed by utilizing the rolling extrusion between the extrusion column and the side pressure receptor. The rolling extrusion has the characteristics of low friction and less wear, and can effectively prevent damage to the components.

[0024] A driving system with an extrusion swing arm, the driving system includes a driving part and a transmission part, the transmission part is connected to the driving part, the transmission part is slidably arranged on the side pressure piece, and the toggle part is arranged on the transmission part; the driving part acts on the transmission part, and the toggle part is applied to the side pressure piece for compression sealing with the side pressure receptor through the extrusion part under the action of the driving part.

[0025] Therefore, the driving system is used to realize the driving of the extrusion swing arm, so as to facilitate the extrusion and pushing of the side pressure piece by the extrusion swing arm.

[0026] In summary, the extruded swing arm and the extruded swing arm provided by the present invention have the following technical effects:

[0027] The present invention uses the toggle part to toggle the extrusion part, and the extrusion part squeezes and pushes the side pressure piece, so as to complete the side pressure of the side pressure piece, that is, the side pressure piece and the side pressure receptor are squeezed and sealed. When the side pressure piece needs to move, the squeezing and pushing of the side pressure piece by the squeezing part is released, and the squeezing and sealing between the side pressure piece and the side pressure receptor are released immediately. Therefore, when the side pressure piece moves, there is no friction between the side pressure piece and the side pressure receptor, thereby avoiding the friction between the side pressure piece and the side pressure receptor when the side pressure piece moves.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0041] Embodiment 1

[0042] See also Figure 1 , Figure 2 , Figure 3 and Figure 4The present invention discloses an extruded swing arm, which comprises:

[0043] The toggle part 1 is preferably a toggle block 11, a toggle groove 12 is provided on a side of the toggle block 11, and one side of the toggle groove 12 is an open structure.

[0044] Further, see Figure 5 The toggle groove 12 includes a low toggle groove 121 and a high toggle groove 122 , a step is formed between the high toggle groove 122 and the low toggle groove 121 , and a transition slope 13 is provided at the connection between the high toggle groove 122 and the low toggle groove 121 .

[0045] Particularly, a portion of the side wall of the toggle slot 12 protrudes outward in a direction away from the toggle slot 12 to form a receiving position 14 , and the connection position between the toggle slot 12 and the receiving position 14 is a slope transition structure.

[0046] See also Figure 6 The extrusion portion 2 includes a connection seat 21 and a rotating handle 22. The connection seat 21 is arranged on the side pressure member 5, and one end of the rotating handle 22 is rotatably connected to the connection seat 21.

[0047] The rotating handle 22 can be rotated and can also move axially along the rotating shaft that the rotating handle 22 and the connecting seat 21 are connected to. Figure 7 The rotating handle 22 includes a rotating body 221, a handle body 222, a spring 223, a connecting pin 224 and a blocking piece 225.

[0048] The rotating body 221 includes a fixed seat 2211 and a rotating seat 2212. The fixed seat 2211 is arranged on the connecting seat 21. A cavity is arranged in the middle of the fixed seat 2211. The connecting seat 21 is provided with a through hole connected to the cavity. An annular clamp is arranged at one end of the cavity away from the connecting seat 21.

[0049] The rotating seat 2212 is connected to one end of the handle body 222 , and the rotating seat 2212 includes an outer shell 22121 and an inserting protrusion 22122 . The inserting protrusion 22122 is arranged in the outer shell 22121 , and the inserting protrusion 22122 is inserted in the annular clamping ring and the cavity, and the outer shell 22121 is sleeved on the outside of the fixed seat 2211 .

[0050] The spring 223 is arranged in the cavity, and the spring 223 is sleeved on the plug-in protrusion. The connecting nail 224 fixes the baffle 225 to one end of the plug-in protrusion 22122 plugged into the cavity, that is, the spring 223 is located between the baffle 225 and the annular collar.

[0051] To prevent the rotating seat 2212 from excessively rotating, an annular protrusion 22111 is provided on the circumferential side of the fixed seat 2211. The annular protrusion 22111 is provided with a break. Correspondingly, a protrusion 22123 is provided at one end of the outer shell of the rotating seat 2212 away from the handle body 222. The protrusion 22123 is arranged between the break.

[0052] A pushing column 23 is disposed on the handle body 222 . Preferably, the pushing column 23 is disposed between two ends of the handle body 222 , and one end of the pushing column 23 is disposed in the toggle slot 12 .

[0053] Furthermore, a pressing column 24 is provided on the handle body 222 opposite to the pushing column 23, and the pressing column 24 is located at one end of the handle body 222 away from the rotating body 221;

[0054] In particular, the extrusion column 24 includes a column 241, a sleeve 242 and a fixing pin 243. The column 241 is arranged on the handle body 222, the sleeve 242 is sleeved on the column 241, and the fixing pin 243 passes through the top of the sleeve 242 to limit the sleeve 242 on the column 241, and the sleeve 242 rotates on the column 241.

[0055] Since the sleeve 242 is used for extrusion and pushing, the sleeve 242 is prone to wear. By setting the fixing nail 243, the fixing nail 243 can be conveniently used for disassembly and replacement of the sleeve 242; furthermore, the sleeve 242 rotates on the column 241. When the sleeve 242 is used for extrusion and pushing, there is rotational friction between the sleeve 242 and the extrusion baffle 41, and the rotational friction effectively reduces the friction wear of the sleeve 242.

[0056] The driving system 3 includes a driving part 31 and a transmission part 32. Preferably, the driving part 31 is a handle, and the transmission part 32 includes at least one transmission rod 321. Specifically, in the present embodiment, there are two transmission rods 321, and the two transmission rods 321 are arranged perpendicular to each other. The two transmission rods 321 are connected by an angle turner 322. One of the transmission rods 321 of the transmission part 32 is connected to the handle through a connecting rod 323. The two transmission parts 32 are connected to the handle up and down. Specifically, a C-shaped structure is formed between the two transmission parts 32 and the handle.

[0057] See also Figure 1 , Figure 4 and Figure 8 Each transmission rod 321 is provided with at least one extrusion swing arm. In this embodiment, the transmission rod 321 is provided with one extrusion swing arm.

[0058] In this embodiment, the side pressure member 5 is a door leaf / window leaf, and the connection relationship between the door leaf / window leaf, the extrusion swing arm and the driving system 3 is that the driving system 3 is arranged around the outer periphery of the door leaf / window leaf. Specifically, the transmission rod 321 of the driving system 3 is slidably connected to the side wall of the door leaf / window leaf, and the connecting seat 21 is arranged on the side wall of the door leaf / window leaf. Specifically, the connecting seat 21 is located on one side of the transmission rod 321, and the toggle block 11 is arranged on the outer side of the transmission rod 321. The opening structure of the toggle groove 12 of the toggle block 11 faces away from the side pressure member 5, and the handle body 222 of the rotating handle 22 is inclined toward the direction of the toggle block 11, and the push column 23 on the rotating handle 22 is slidably arranged in the toggle groove 12.

[0059] After completing the installation of the door / window sash, extrusion swing arm and drive system 3 as mentioned above, the door / window sash is finally installed in the outer frame 4, so the side pressure receptor is the outer frame 4. Since the door / window sash can be pushed and pulled in the outer frame 4, a roller portion 6 is provided at the bottom / top of the door / window sash. It should be noted that the side pressure of the door / window sash is a horizontal movement perpendicular to the direction of movement of the roller portion 6. Therefore, it can be understood that the door / window sash and the roller portion 6 are in a sliding connection.

[0060] In the initial state (that is, the door / window sash is not in the lateral pressure state), driven by the handle, the transmission rod 321 moves in the direction away from the handle, and this direction is named the lateral pressure movement direction. At this time, the extrusion swing arm squeezes the door / window sash for lateral pressure, so in the initial state, the rotating body 221 of the rotating handle 22 is located in the front side of the lateral pressure movement direction of the transmission rod 321, and the pushing column 23 is simultaneously located in the receiving position 14 and the low-position toggle groove 121, and at the same time, the handle body 222 is located at the end away from the rotating body 221 and is completely located in the toggle groove 12, and the part of the toggle groove 12 without the receiving position 14 is away from the rotating body 221; an extrusion baffle 41 is provided on the outer frame 4, and the extrusion baffle 41 is located on one side of the opening structure of the toggle groove 12, and at this time, the top surface of the extrusion column 24 is located between the top surface of the extrusion baffle 41 and the handle body.

[0061] The specific side pressure principle of the door / window sash is: turn the handle, and under the drive of the handle, the connecting rod 323 drives the transmission rod 321 to move in the direction away from the handle. When the toggle block 11 on the transmission rod 321 pushes the pushing column 23 in the receiving position 14 to move toward the toggle groove 12, the pushing column 23 simultaneously moves from the low-position toggle groove 121 along the transition slope 13 to the high-position toggle groove 122, and the rotating seat 2212 moves in the direction away from the connecting seat 21. Since the rotating seat 2212 drives the baffle 225 to move in the cavity of the fixed seat 2211, the baffle 225 compresses the spring 223, and the extrusion column 24 moves in the direction of the extrusion baffle 41. The top surface of the extrusion column 24 is located at the extrusion The handle 222 is between the top surface of the pressure baffle 41 and the bottom of the extrusion baffle 41. At this time, the handle body 222 rotates along the movement direction of the toggle block 11. When the pushing column 23 reaches the toggle slot 12, the sleeve 242 of the extrusion column 24 follows the handle body 222 to rotate to the outside of the opening structure of the toggle slot 12, and the side of the sleeve 242 abuts against the side of the extrusion baffle 41. The handle continues to be rotated, and the handle body 222 continues to rotate along the movement direction of the toggle block 11. Therefore, under the extrusion and push of the sleeve 242 and the extrusion baffle 41, the door / window sash moves on the roller part 6 in a direction perpendicular to the movement of the roller part 6 toward the inside of the outer frame 4, and finally the inner wall of the door / window sash is laterally pressed against the inside of the outer frame 4.

[0062] The process of relieving the lateral pressure of the door / window sash is as follows: the handle is rotated in the opposite direction, the connecting rod 323 drives the transmission rod 321 to move in the direction of the handle, the toggle block 11 on the transmission rod 321 follows the transmission rod 321 to move in the direction of the handle, and the handle body 222 rotates again along the movement direction of the toggle block 11, and finally the sleeve 242 is separated from the extrusion baffle 41. Under the action of the restoring force of the spring 223, the spring 223 drives the rotating seat 2212 to move in the direction of the fixed seat 2211 by pushing the baffle 225, and finally pushes the column 23 back to the low-position toggle groove 121. At this time, the door / window sash moves on the roller part 6 toward the outside of the outer frame 4 in a direction perpendicular to the movement of the roller part 6, and finally the inner wall of the door / window sash and the inside of the outer frame 4 are relieved of the lateral pressure.

[0063] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above-mentioned technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
