Description

Technical Field

[0001] The invention relates to the field of sealing equipment, and in particular to a side pressure sealing system. Background Art

[0002] In the sealing of sliding doors and windows, since there is a pushing and pulling movement in sliding doors and windows, a sealing strip is set on the inner side of the door leaf / window leaf. However, there is an interference fit between the sealing strip and the outer frame, that is, the sealing strip is pressed against the outer frame to achieve sealing between the door leaf / window leaf and the outer frame.

[0003] Therefore, when the door / window sash is pushed or pulled, the sealing strip will produce friction with the outer frame, and the friction between the sealing strip and the outer frame will cause the movement of the door / window sash to jam, affecting the user experience; secondly, the friction will cause wear of the sealing strip and the outer frame, resulting in loss of components. 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 a side pressure sealing system.

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

[0006] Side pressure mechanism;

[0007] The driving mechanism comprises a driving body and a pushing part, one end of the pushing part is connected to the side pressure mechanism, and the other end is connected to the driving body, the pushing part applies pressure to the side pressure mechanism for compression sealing with the side pressure receptor under the action of the driving body; and / or releases the pressure applied by the pushing part to the side pressure mechanism for compression sealing with the side pressure receptor under the action of the driving body.

[0008] In the present invention, the driving body drives the pushing part to squeeze and push the side pressure mechanism, so as to complete the side pressure of the side pressure mechanism on the side pressure receptor. When the side pressure mechanism is moved, the driving body releases the side pressure of the side pressure mechanism on the side pressure receptor, so that when the side pressure mechanism moves, there is no friction between the side pressure mechanism and the side pressure receptor, so that the movement of the side pressure mechanism is smooth, and the wear of the side pressure mechanism and the side pressure receptor is also avoided.

[0009] Furthermore, the side pressure mechanism includes a side pressure member and a rolling member, and the side pressure member is slidably disposed on the rolling member to slide in a horizontal direction perpendicular to the movement direction of the rolling member.

[0010] Thus, the driving mechanism drives the side pressure member to slide on the rolling member and perform side pressure sealing or separation with the side pressure receptor. After the side pressure member is separated from the side pressure receptor, the side pressure member moves through the rolling member.

[0011] Furthermore, it also includes a transmission guide part, which is arranged on the rolling element and is used for transmission guidance of the driving body.

[0012] Therefore, the transmission guide part guides and limits the driving mechanism, thereby ensuring the driving operation stability of the driving mechanism.

[0013] Furthermore, the transmission guide part includes a guide plate and a guide rod, the guide plate is arranged on the rolling element, the guide plate is provided with a guide groove, one side of the guide groove is provided with an avoidance position, one end of the guide rod is connected to the driving body, and the other end is inserted into the guide groove.

[0014] Therefore, the guide groove guides the movement of the driving body, which is beneficial to the stability of the movement of the driving body. At the same time, the clearance on one side of the guide groove avoids the extrusion and interference between the guide rod and the side wall of the guide groove when the side pressure piece is pressed sideways.

[0015] Furthermore, the pushing part includes a toggle member and an extrusion member, the toggle member is arranged on the driving body, one end of the extrusion member is connected to the toggle member, and the other end of the extrusion member is connected to the side pressure member.

[0016] Thus, the driving body drives the movement of the toggle member, and then the toggle member drives the extrusion member to push the side pressure member to extrude the side pressure receptor. The side pressure of the side pressure member is achieved through multiple components, and the side splitting of multiple components makes the loading, unloading and replacement of components more convenient.

[0017] Furthermore, the toggle member is a toggle block, and a toggle groove for toggle the extrusion member is provided on a side of the toggle block away from the driving body;

[0018] The extrusion member includes a rotating body and a handle body, wherein the rotating body is arranged on the side pressure member, one end of the handle body is connected to the rotating body, a pushing column is arranged on the handle body, the pushing column is located between the two ends of the handle body, and one end of the pushing column is slidably arranged in the toggle groove.

[0019] Therefore, the handle body is pushed by the abutment between the toggle groove and the push column. The assembly relationship between the toggle groove and the push column is simple, and no other connecting components are required to connect the two, which has the characteristics of simplified structure.

[0020] Furthermore, the rotating body includes a fixed seat, a rotating seat, a spring and a baffle, the fixed seat is arranged on the side pressure piece, the rotating seat is respectively plugged into the fixed seat and connected to the handle body, the spring is arranged in 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.

[0021] Therefore, the insertion of the fixed seat and the rotating seat facilitates the rotation of the handle body, and the handle body pushes the side pressure piece and the side pressure receptor to perform side pressure sealing by rotating.

[0022] 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.

[0023] Therefore, the low-position toggle groove and the high-position toggle groove are used to change the relative positions of the handle body and the fixed seat. When the handle body is located in the high-position toggle groove, the rotation of the handle body 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 handle body is received in the low-position toggle groove. If the side pressure piece moves at this time, it can effectively prevent the handle body from colliding with other components.

[0024] Furthermore, part of the side wall of the toggle slot protrudes outward in a direction away from the toggle slot and forms a receiving position for receiving an end of the handle body away from the rotating body.

[0025] Thus, the receiving position completely receives the end of the handle body away from the rotating body, thereby preventing the handle body from protruding out of the toggle slot and colliding with or interfering with other components.

[0026] Furthermore, an extrusion column is rotatably provided at one end of the handle body away from the rotating body, and the extrusion column rolls and squeezes to push the side pressure piece to apply pressure to the side pressure receptor.

[0027] Thus, the side pressure of the side pressure piece is pushed by the rolling extrusion of the extrusion column and the outer frame, and the rolling extrusion has the advantages of small friction coefficient and low wear degree.

[0028] Furthermore, the transmission guide portion also includes a fixing plate, and the guide plate is connected to the rolling element via the fixing plate.

[0029] Therefore, the guide plate is connected to the rolling element through the fixing plate, which effectively improves the connection stability between the guide plate and the rolling element.

[0030] In summary, the side pressure sealing system provided by the present invention has the following technical effects:

[0031] 1. The driving body drives the pushing part to squeeze and push the side pressure mechanism, so as to complete the side pressure of the side pressure mechanism on the side pressure receptor. When the side pressure mechanism is moved, the driving body releases the side pressure of the side pressure mechanism on the side pressure receptor. When the side pressure mechanism moves, there is no friction between the side pressure mechanism and the side pressure receptor, so that the movement of the side pressure mechanism is smooth, and the wear of the side pressure mechanism and the side pressure receptor is also avoided.

[0032] 2. The transmission guide part guides and limits the driving mechanism, ensuring the driving operation stability of the driving mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Embodiment 1

[0047] See also Figure 1 and Figure 3 The present invention discloses a side pressure sealing system, which includes:

[0048] The side pressure mechanism 3 includes a side pressure member 31 and a rolling member 32. In the present embodiment, the side pressure member 31 is a door leaf / window leaf. The driving body 11 includes a handle 111 and two transmission parts 112 symmetrically arranged up and down, and the two transmission parts 112 are connected through the handle 111. Specifically, the handle 111 is arranged on the door leaf / window leaf, and the transmission part 112 includes two transmission rods 1121, a corner turner 1122 and a connecting rod 1123. The two transmission rods 1121 are arranged with each other through the corner turner 1122, and one of the transmission rods 1121 in the transmission part 112 is connected to the handle 111 through the connecting rod 1123. It can be seen that the entire driving body 11 is a C-shaped structure, and the transmission rod 1121 of the transmission part 112 is slidably arranged on the side of the door leaf / window leaf.

[0049] See also Figure 5 and Figure 6The pushing portion 12 includes a toggle piece 121 and an extrusion piece 122. A plurality of pushing portions 12 can be provided on each transmission rod 1121. In the present embodiment, preferably, each transmission rod 1121 is provided with a pushing portion 12. Specifically, the toggle piece 121, that is, the toggle block is provided on the outer side of the transmission rod 1121. Preferably, the toggle block and the transmission rod 1121 can slide, and finally the toggle block and the transmission rod 1121 are fixed by screws. The toggle block and the transmission rod 1121 can slide to facilitate the adjustment of the position of the toggle block. A toggle groove 14 is provided on the side of the toggle block away from the transmission rod 1121. Specifically, one side of the toggle groove 14 is an open structure; the extrusion piece 122 includes a rotating body 1221 and a handle body 1222. The rotating body 1221 is provided with a toggle groove 14. The body 1221 is connected to the door leaf / window leaf through a connecting seat 1226, and the connecting seat 1226 is located on the non-open side of the toggle slot 14 of the toggle block. Specifically, the rotating body 1221 includes a fixed seat 12211, a rotating seat 12212, a spring 12213 and a baffle 12214. The fixed seat 12211 is arranged on the side pressure piece 31, one end of the rotating seat 12212 is plugged into the fixed seat 12211, and the other end is connected to the handle body 1222. The spring 12213 is arranged in the fixed seat 12211 and is sleeved on the rotating seat 12212. The baffle 12214 is arranged on one end of the rotating seat 12212 and the fixed seat 12211 is plugged into the fixed seat 12211 through a connecting screw 1225, so as to limit the spring 12213 on the rotating seat 12212.

[0050] In particular, in order to control the rotation angle of the handle body 1222, an annular sleeve with a notch is arranged on the outer periphery of the fixed seat 12211, and the annular sleeve is arranged on the connecting seat 1226. Correspondingly, an outer shell is arranged on the outside of the rotating seat 12212, and the outer shell is sleeved on the outside of the fixed seat 12211. A locking protrusion is arranged on the bottom of the outer shell, and the locking protrusion is inserted into the notch of the annular sleeve. The notch size of the annular sleeve is set according to the rotation angle of the handle body 1222. When the handle body 1222 rotates, the locking protrusion moves between the notches of the annular sleeve.

[0051] The pushing column 1223 is located between two ends of the handle body 1222 , and one end of the pushing column 1223 is slidably disposed in the toggle slot 14 .

[0052] Furthermore, in order to avoid extrusion and wear of the handle body 1222, an extrusion column 1224 is rotatably provided at one end of the handle body 1222 away from the rotating body 1221, and the rolling extrusion of the extrusion column 1224 is used to push the door leaf / window leaf for side pressure. Specifically, the extrusion column 1224 and the pushing column 1223 are arranged on two side surfaces of the handle body 1222 opposite to each other, and the extrusion column 1224 includes a sleeve column 12241, a roller 12242 and a fixing screw 12243. The sleeve column 12241 is arranged on the handle body 1222, and the roller 12242 is sleeved on the sleeve column 12241. The fixing screw 12243 limits the roller 12242 on the sleeve column 12241, and the roller 12242 rolls on the sleeve column 12241. Since the roller 12242 is subjected to extrusion and wear, the fixing screw 12243 can facilitate the removal and replacement of the roller 12242.

[0053] Furthermore, the toggle groove 14 includes a low toggle groove 141 and a high toggle groove 142 , a step is formed between the high toggle groove 142 and the low toggle groove 141 , and a transition slope 16 is provided at the connection between the high toggle groove 142 and the low toggle groove 141 .

[0054] In addition, part of the side wall of the toggle slot 14 protrudes outward in a direction away from the toggle slot 14 and forms a receiving position 15 for receiving the end of the handle body 1222 away from the rotating body 1221. Specifically, the receiving position 15 is located on the non-open side of the toggle slot 14, and the middle position of the receiving position 15 is located on one side of the transition slope 16.

[0055] Further, see Figure 7 and Figure 4 The side pressure sealing system also includes a transmission guide part 2, which includes a guide plate 21 and a guide rod 23. The guide plate 21 is provided with a guide groove 211. One end of the guide rod 23 is connected to the transmission rod 1121 of the driving body 11, and the other end is inserted into the guide groove 211. One side of the guide groove 211 is provided with an avoidance position 212 to avoid interference between the guide rod 23 and the guide plate 21 when the side pressure member 31 is side pressed. The guide plate 21 is arranged on the rolling member 32; specifically, the guide rod 23 is slidably arranged on the transmission rod 1121, and the guide rod 23 is finally positioned with the transmission rod 1121 by a set screw. The sliding connection between the guide rod 23 and the transmission rod 1121 facilitates the adjustment of the position of the guide rod 23, which is more conducive to the installation and debugging of the side pressure sealing system. Preferably, in order to better ensure that the guide rod 23 switches between the guide groove 211 and the avoidance position 212, a transition slope 213 is arranged at the connection position of the guide groove 211 and the avoidance position 212.

[0056] The transmission guide part 2 also includes a fixed plate 22, and the guide plate 21 is connected to the rolling member 32 through the fixed plate 22. Specifically, the length of the fixed plate 22 is greater than that of the guide plate 21, and the guide plate 21 is vertically arranged in the middle of one side of the fixed plate 22. Preferably, the guide plate 21 is vertically arranged on the fixed plate 22 as an integral part, so as to facilitate the processing and production of the transmission guide part 2. In order to eliminate the bending stress at the connection between the guide plate 21 and the fixed plate 22, two notches 221 are provided on the side where the fixed plate 22 and the guide plate 21 are connected. The two notches 221 are respectively located on both sides of the side where the guide plate 21 and the fixed plate 22 are connected. Preferably, a transmission rod 1121 provided with a guide rod 23 is located above the guide plate 21.

[0057] Particularly, a plurality of rolling elements 32 are respectively disposed at the top / bottom of the door leaf / window leaf. In the present embodiment, specifically, two rolling elements 32 are respectively disposed at the top / bottom of the door leaf / window leaf.

[0058] The entire side pressure mechanism 3 is installed in the outer frame 4. It should be noted that the rolling parts 32 at the top / bottom of the door / window sash are respectively rollingly connected to the top / bottom of the outer frame 4. In particular, an extrusion baffle 41 is provided in the outer frame 4, and the extrusion baffle is located on the side of the opening structure of the toggle slot 14 of the toggle block.

[0059] See also Figure 8 In the initial state (that is, the door / window sash is not in the side pressure state), driven by the handle 111, the transmission rod 1121 moves in the direction away from the handle 111, and this direction is named the side pressure driving direction. At this time, the pushing portion 12 squeezes the door / window sash for side pressure, so in the initial state, the rotating body 1221 is located in the side front of the side pressure driving direction of the transmission rod 1121, and the pushing column 1223 is simultaneously located in the receiving position 15 and the low-position toggle groove 141, and the end of the handle body 1222 away from the rotating body 1221 is completely located in the toggle groove 14, and the part of the toggle groove 14 without the receiving position 15 is away from the rotating body 1221; at this time, the top surface of the squeezing column 1224 is located between the top surface of the squeezing baffle 41 and the handle body 1222.

[0060] The guide rod 23 on the driving mechanism 1 is located at one end of the guide groove 211 away from the avoidance position 212 , and one end of the guide groove 211 provided with the avoidance position 212 is located in front of the side pressure driving direction.

[0061] The specific side pressure principle of the door / window sash is as follows: turn the handle 111, and under the drive of the handle 111, the connecting rod 1123 drives the transmission rod 1121 to move in the direction away from the handle 111, and the toggle block on the transmission rod 1121 pushes the pushing column 1223 in the receiving position 15 to move toward the toggle groove 14, and the pushing column 1223 simultaneously moves from the low-position toggle groove 141 along the transition slope 16 to the high-position toggle groove 142, and the handle body 1222 drives the rotating seat 12212 to move in the direction away from the connecting seat 1226. Since the rotating seat 12212 drives the baffle 12214 to move in the fixed seat 12211, the baffle 12214 compresses the spring 12213, and the extrusion column 1224 moves in the direction of the extrusion baffle 41. At this time, the extrusion column 12 The top surface of 24 is located between the top surface of the extrusion baffle 41 and the bottom of the extrusion baffle 41, and the handle body 1222 rotates along the movement direction of the toggle block (that is, the side pressure driving direction). When the pushing column 1223 reaches the toggle slot 14, the roller 12242 of the extrusion column 1224 follows the handle body 1222 to rotate to the outside of the opening structure of the toggle slot 14, and the side of the roller 12242 abuts against the side of the extrusion baffle 41. The handle 111 continues to be rotated, and the handle body 1222 continues to rotate along the movement direction of the toggle block. Therefore, under the extrusion and push of the roller 12242 and the extrusion baffle 41, the door leaf / window leaf moves on the rolling element 32 in a direction perpendicular to the movement of the rolling element 32 toward the inside of the outer frame 4, and finally the inner wall of the door leaf / window leaf is laterally pressed against the inside of the outer frame 4.

[0062] Correspondingly, when the transmission rod 1121 moves in the direction away from the handle, the guide rod 23 on the transmission rod 1121 moves from the end of the guide groove 211 away from the avoidance position 212 to the end of the guide groove 211 with the avoidance position 212. In the process of the guide rod 23 moving from the end of the guide groove 211 away from the avoidance position 212 to the end of the guide groove 211 with the avoidance position 212, the side of the roller 12242 and the side of the extrusion baffle 41 are also abutted and extruded synchronously. Therefore, driven by the door / window sash, the guide rod 23 will follow the transition slope 213 from the end of the guide groove 211 away from the avoidance position 212 into the avoidance position 212. When the door / window sash completes the side pressure, the guide rod 23 is just in the avoidance position 212. Therefore, the avoidance position 212 provides an avoidance position for the guide rod 23 in the side pressure state of the door / window sash, preventing the guide rod 23 from interfering with and squeezing the inner wall of the guide groove 211, and avoiding the problem of inadequate side pressure sealing of the door / window sash.

[0063] The process of relieving the lateral pressure of the door / window sash is as follows: the handle 111 is rotated in the opposite direction, the connecting rod 1123 drives the transmission rod 1121 to move in the direction of the handle 111, and the toggle block on the transmission rod 1121 follows the transmission rod 1121 to move in the direction of the handle 111. When the receiving position 15 moves to the position of the pushing column 1223, the roller 12242 is finally released from contact with the extrusion baffle 41, and the pushing column 1223 returns from the high-position toggle groove 142 to the position of the low-position toggle groove 141. Under the action of the restoring force of the spring 12213, the spring 12213 drives the rotating seat 12212 to move in the direction of the fixed seat 12211 by pushing the baffle 12214, and finally the pushing column 1223 returns from the high-position toggle groove 142 to the low-position toggle groove 141, and finally the inner wall of the door / window sash and the inner part of the outer frame 4 are relieved of the lateral pressure.

[0064] Correspondingly, when the transmission rod 1121 moves in the direction of the handle, the guide rod 23 on the transmission rod 1121 moves from the avoidance position 212 to the end of the guide groove 211 away from the avoidance position 212. During this process, the side wall of the guide rod 23 will be close to the transition slope 213, so under the action of the reverse rotation of the handle 111, the transition slope 213 generates an outward pushing force on the guide rod 23, so the door leaf / window leaf follows the outer side of the outer frame 4 outside the guide rod 23, and then the door leaf / window leaf is released from the side pressure fit with the inner side of the outer frame.

[0065] 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.
