Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hardware fittings, in particular to a novel damper for sliding doors and windows. BACKGROUND

[0002] In the existing market, dampers are usually arranged on some sliding doors and windows (such as cabinet doors and windows) to play a buffering role. When the door leaf or window leaf is opened or closed, the damper assists in opening or closing, thereby reducing collision and noise.

[0003] A damper for a bidirectional damping system is disclosed in the prior art (Patent No. 201721125021.1), a guide groove is formed in the side surface of the shell, and the two sides of the driving block have outwardly protruding guide blocks. Through the cooperation of the guide groove and the guide blocks, a guide structure of the driving block is formed. After a long period of actual application, it is found that the above structure has the following serious defects and shortcomings:

[0004] ① The damper structure needs to open a guide groove in the middle of the shell, so that the shell can usually only be processed from sheet metal parts. Sheet metal parts have lower structural strength compared to other materials, and are difficult to avoid deformation after a long period of use. If other materials are used for processing, the processing technology is too complex, the cost is extremely high, the production efficiency is extremely low, and it cannot be used as a conventional material for actual use;

[0005] ② The damper structure needs to place the guide blocks into the guide groove, so the shell needs to be processed into two halves during the production process. The driving block is placed into the two half shells, and then the two half shells are assembled. Aligning and assembling the two half shells requires extremely high assembly process requirements, and the scrap rate during the assembly process is extremely high. In addition, in combination with the first point above, the shell formed by assembling the two half sheet metals is also more prone to structural deformation;

[0006] ③ In order to make the driving block sink quickly when it reaches the end position of the guide groove to achieve the quick unhooking action, and to keep the tension spring in the stretched state when the driving block is unhooked, a nearly vertical corner is provided at the end of the guide groove, so that the driving block sinks when it reaches the end position of the guide groove, and the tension spring is prevented from moving the driving block back. However, since the corner is too close to vertical, it is difficult to move the driving block back to the inside. If the corner is not provided or is not vertical enough, the driving block cannot sink quickly and cannot be prevented from moving back.

[0007] Therefore, there is an urgent need in the prior art to invent a damper for sliding doors and windows that can overcome the above defects. SUMMARY

[0008] In order to overcome the technical problems of the existing technology, such as deformation of the damper for sliding doors after long time use and complex assembly process, the present application provides a new damper for sliding doors, which has the characteristics of simple and reasonable structure design, high structural strength, no structural deformation, simple production and assembly operation, and no need to set a vertical corner section of the guide slot.

[0021] Further, the first elastic member is a compression spring, the limiting end, which is connected with one end of the first elastic member, is provided with a protruding structure, and the protruding structure is inserted into the first elastic member.

[0022] The new damper for the sliding door and window disclosed above can make the limiting end of the second limiting member rotate in the direction of the poking block under the elastic force of the first elastic member when the control end of the second limiting member is not in contact with the end of the shell, and finally abut against the upward rotating poking block, so that the poking block is kept in the position above the box body under the action of the limiting end.

[0023] Further, the poking block is provided with a first limiting slot, and when the limiting end abuts against the poking block, the limiting end is clamped in the first limiting slot to limit the rotation of the poking block.

[0024] Further, the poking block is provided with a second limiting slot, and when the first limiting member abuts against the poking block, the first limiting member is clamped in the second limiting slot to limit the movement of the box body in the inside of the shell.

[0025] The new damper for the sliding door and window disclosed above can be used to realize better structural cooperation between the poking block and the first limiting member, and between the poking block and the second limiting member.

[0026] Further, the second limiting member is fixed at one end of the knob away from the first rotating shaft, and the first limiting member is a limiting hole arranged at the bottom of the shell; when in the supporting position, the second limiting member abuts against the bottom of the shell to keep the knob in the upper position, and the second limiting member and the knob can slide synchronously relative to the shell; when in the releasing position, the second limiting member is opposite to the limiting hole, and the second limiting member can be inserted into the limiting hole to make the knob rotate and keep in the sunken position.

[0059] Embodiment 1

[0060] Reference Figures 1-5 As shown in the first embodiment of the present application, the new damper for sliding door and window includes a shell 1, a box body 2, a push block 3 and a second limiting piece 5, the box body 2 is movably arranged inside the shell 1, and the inside of the shell 1 is also provided with a first limiting piece 4. Among them, the shell 1 is used for fixedly installed on the door body of the sliding door, and plays a role of reducing collision and noise when the door leaf is opened or closed. The box body 2 can move inside the shell 1 along the length direction of the shell 1, and the box body 2 is used for arranging the push block 3, the second limiting piece 5 and the like, that is, the box body 2 is used as a bearing component of the above structure, so as to realize the movement of the push block 3, the second limiting piece 5 and the like in the length direction of the shell 1.

[0061] Further, in the embodiment, the toggle block 3 is rotatably arranged in the interior of the box body 2 through the first rotating shaft 6, and the second limiting piece 5 is configured to be movable between a supporting position and a releasing position; when being at the supporting position, the second limiting piece 5 can limit the rotation of the toggle block 3 to keep the toggle block 3 at the upper position; when being at the releasing position, the second limiting piece 5 can release the rotation limitation of the toggle block 3, and the toggle block 3 is rotated to sink under the action of gravity at the end far away from the first rotating shaft 6 to rotate to the sinking position, and the first limiting piece 4 is configured to keep the toggle block 3 at the sinking position.

[0062] Preferably, in the embodiment, the interior of the box body 2 is further provided with a second rotating shaft 7, and the second limiting piece 5 is rotatably arranged in the interior of the box body 2 through the second rotating shaft 7. Specifically, the first rotating shaft 6 and the second rotating shaft 7 are both arranged along the width direction of the shell 1 and are respectively used to realize the rotary motion of the toggle block 3 and the second limiting piece 5 in the interior of the box body 2. More specifically, the second limiting piece 5 includes a limiting end 51 and a control end 52 arranged at both sides of the second rotating shaft 7, when the box body 2 moves towards the end of the shell 1 and the control end 52 contacts the end of the shell 1, the control end 52 rotates towards the toggle block 3, and the limiting end 51 rotates away from the toggle block 3, that is, away from the toggle block 3 to make the second limiting piece 5 at the releasing position. Conversely, when the control end 52 does not contact the end of the shell 1, the control end 52 rotates away from the toggle block 3, and the limiting end 51 rotates towards the toggle block 3, that is, towards the toggle block 3 to make the second limiting piece 5 at the supporting position.

[0063] In the technical scheme of the embodiment, the first limiting piece 4 and the second limiting piece 5 are arranged in the interior of the shell 1 to realize the switching of the two states of the toggle block 3, specifically as follows:

[0064] ① When the box body 2 is located at the end of the shell 1, the control end 52 of the second limiting piece 5 contacts the object at the end of the shell 1, the limiting end 51 is away from the toggle block 3, the toggle block 3 rotates downward (that is, sinks) around the first rotating shaft 6 under the action of gravity, and rotates to abut against the first limiting piece 4, at this time, the toggle block 3 cannot move under the blocking action of the first limiting piece 4, and the box body 2 cannot move in the interior of the shell 1, thereby avoiding the toggle block 3 from moving back;

[0065] ② When the box body 2 is not located at the end of the shell 1, the control end 52 of the second limiting piece 5 does not contact the end of the shell 1, the limiting end 51 is close to the toggle block 3, the toggle block 3 rotates upward around the first rotating shaft 6 under the action of the damping toggle block a and abuts against the limiting end 51, and the toggle block 3 is kept at the upper position under the action of the limiting end 51 and cannot rotate downward, so as to make the box body 2 restore to the movable state in the interior of the shell 1.

[0066] Therefore, in the embodiment, the first limiting piece 4 is arranged to avoid the return of the knob 3, and the guiding block, the guiding groove and the vertical corner segment are not arranged, so that the corner of the guiding groove is not too close to the vertical direction, the knob is not difficult to be pulled back, and the technical problems are avoided, and the structure design is simple and reasonable.

[0067] More specifically, the box 2 and the knob 3 are slidably arranged in the shell 1, the damping function of the new damper for the sliding door and window is realized, the guiding groove is not arranged on the shell 1, the shell 1 is made of the high-strength and high-performance material other than the sheet metal, the structure and the material of the shell 1 are upgraded, the overall structural strength is high, the stability is good, the structural deformation of the shell 1 is avoided in the long-term use, and the precision of the overall structure of the shell 1 is controlled in the production process.

[0068] In the embodiment, the shell 1 is preferably formed by the integrally stretched aluminum profile, which has the advantages of light weight, good forming, high strength, corrosion resistance, long service life, renewable, less pollution, low maintenance cost and the like. It should be noted that in some other embodiments, the shell 1 of the present application can also be formed by the integrally formed steel alloy profile or steel profile, but is not limited to this.

[0069] In the embodiment, the working process and working principle of the new damper for the sliding door and window are as follows:

[0070] a. Before the door closing operation, referring to the first drawing, Figure 6 the initial state of the new damper for the sliding door and window is that the box 2 is arranged close to the end of the shell 1, the control end 52 of the second limiting piece 5 is in contact with the end of the shell 1, the limiting end 51 is away from the knob 3, the knob 3 is in abutment with the first limiting piece 4 in the shell 1, and the knob 3 cannot be returned under the action of the tension spring.

[0071] b. When the door closing operation is performed, referring to the second drawing, Figure 6As shown in the second and third figures, the new type of damper used in the sliding door and window moves towards the side of the door frame as the door body moves, that is, to the left in the figure. The actuating block 3 and the damping actuating block a (the damping actuating block a is located on the guide rail and its position is fixed) come into contact and move towards the left end away from the housing 1 under its force. At this time, the damping tube 9 connected to the actuating block 3 plays a buffering and shock absorption role. At the same time, the actuating block 3 rotates upward about the first rotating shaft 6. The second limiting member 5 on the housing 2 also moves towards the left end away from the housing 1. The control end 52 of the second limiting member 5 no longer contacts the object at the end of the housing 1. The limiting end 51 rotates towards the actuating block 3, so that the actuating block 3 and the limiting end 51 abut against each other. Under the force of the limiting end 51, it cannot rotate downward, thereby keeping the actuating block 3 in the upper position of the housing 2.

[0072] c. When the door is fully closed, see Figure 6 As shown in the fourth figure, the box 2 slides to the middle part of the housing 1, the damping actuation block a is locked on the top of the actuation block 3, the box 2 is fixed in this position of the housing 1, and the actuation block 3 is held above the box 2.

[0073] d. When performing the door opening operation, please refer to Figure 7 As shown in the four attached figures, the new type of damper used in this sliding door and window moves away from the side of the door frame as the door body moves, i.e., to the right in the figure. Under the action of the damping actuating block a, the actuating block 3 moves toward the left end of the housing 1. When the housing 2 moves to the end of the housing 1, the control end 52 of the second limiting member 5 contacts the object at the end of the housing 1, causing the limiting end 51 of the other end of the second limiting member 5 to move away from the actuating block 3. After the actuating block 3 loses the action of the limiting end 51, it rotates downward under the action of gravity until it abuts against the first limiting member 4 inside the housing 1. At this time, the actuating block 3 can be prevented from moving back under the action of the tension spring 10 under the blocking and limiting action of the first limiting member 4, and returns to the initial state.

[0074] More specifically, the object at the end of the housing 1 described in this embodiment can be a pulley structure of the novel damper for the sliding door and window, or a rigid structure at the end of the housing 1. No specific limitation is made in the embodiments of the present invention.

[0075] See Figure 2As shown in the preferred scheme of the embodiment, the inside of the box body 2 is further provided with a first elastic member 8, which is used to provide an elastic force to the limiting end 51 in the direction of the poking block 3. In the preferred scheme, when the control end 52 of the second limiting member 5 is not in contact with the object at the end of the shell 1, the limiting end 51 of the second limiting member 5 rotates in the direction of the poking block 3 under the elastic force of the first elastic member 8, and finally abuts against the upwardly rotated poking block 3, so that the poking block 3 is kept in the position above the box body 2 under the action of the limiting end 51.

[0076] Referring to Figure 2 and Figure 4 As shown in another preferred scheme of the embodiment, the first elastic member 8 is a compression spring, and the limiting end 51 is provided with a protruding structure 53 at the end thereof facing the spring, and the protruding structure 53 is inserted into the spring, so that the limiting end 51 and the spring are connected together. Specifically, the first elastic member 8 in the embodiment adopts a spring structure, and in order to adapt to the spring structure, the protruding structure 53 is arranged at the end of the limiting end 51 facing the spring, and the protruding structure 53 is inserted into the spring, so that the two are connected together, and the limiting end 51 rotates in the direction of the poking block 3 under the action of the spring when the control end 52 is not in contact with the object at the end of the shell 1.

[0077] In addition, in another preferred scheme of the embodiment, the first elastic member 8 is a torsion spring, the first elastic member 8 is sleeved on the second rotating shaft 7 and acts on the second limiting member 5, and the second limiting member 5 plays the same role as in the previous preferred scheme under the action of the torsion spring, so that the limiting end 51 rotates in the direction of the poking block 3 under the action of the torsion spring when the control end 52 is not in contact with the object at the end of the shell 1.

[0078] Embodiment 2

[0079] The main difference between the second embodiment of the application and the first embodiment is that the new damper for the sliding door and window discloses two limiting groove structures, which are respectively used to realize better cooperation between the poking block 3 and the first limiting member 4 and between the poking block 3 and the second limiting member 5.

[0080] Referring to Figure 2 and Figure 4As shown in one of the optional solutions of the embodiment, the toggle block 3 is provided with a first limiting groove 31 at one end thereof facing the second limiting member 5. When the limiting end 51 abuts against the toggle block 3, the limiting end 51 is clamped in the first limiting groove 31, thereby limiting the toggle block 3 from rotating downward around the first rotating shaft 6. In the technical solution of the embodiment, the first limiting groove 31 is a groove structure formed by being recessed inward of the toggle block 3 at the end thereof facing the limiting end 51, and the limiting end 51 is a relatively small protruding structure formed by protruding from the second limiting member 5 toward the toggle block 3. When the toggle block 3 rotates upward around the first rotating shaft 6 under the action of the damping toggle block a, the limiting end 51 is clamped in the first limiting groove 31, so that the toggle block 3 cooperates with the second limiting member 5 to block the toggle block 3 from rotating downward and keep the toggle block 3 at the position above the box body 2.

[0081] As shown in one of the optional solutions of the embodiment, the toggle block 3 is provided with a first limiting groove 31 at one end thereof facing the second limiting member 5. When the limiting end 51 abuts against the toggle block 3, the limiting end 51 is clamped in the first limiting groove 31, thereby limiting the toggle block 3 from rotating downward around the first rotating shaft 6. In the technical solution of the embodiment, the first limiting groove 31 is a groove structure formed by being recessed inward of the toggle block 3 at the end thereof facing the limiting end 51, and the limiting end 51 is a relatively small protruding structure formed by protruding from the second limiting member 5 toward the toggle block 3. When the toggle block 3 rotates upward around the first rotating shaft 6 under the action of the damping toggle block a, the limiting end 51 is clamped in the first limiting groove 31, so that the toggle block 3 cooperates with the second limiting member 5 to block the toggle block 3 from rotating downward and keep the toggle block 3 at the position above the box body 2. Figure 1 Figure 4 As shown in one of the optional solutions of the embodiment, the toggle block 3 is provided with a first limiting groove 31 at one end thereof facing the second limiting member 5. When the limiting end 51 abuts against the toggle block 3, the limiting end 51 is clamped in the first limiting groove 31, thereby limiting the toggle block 3 from rotating downward around the first rotating shaft 6. In the technical solution of the embodiment, the first limiting groove 31 is a groove structure formed by being recessed inward of the toggle block 3 at the end thereof facing the limiting end 51, and the limiting end 51 is a relatively small protruding structure formed by protruding from the second limiting member 5 toward the toggle block 3. When the toggle block 3 rotates upward around the first rotating shaft 6 under the action of the damping toggle block a, the limiting end 51 is clamped in the first limiting groove 31, so that the toggle block 3 cooperates with the second limiting member 5 to block the toggle block 3 from rotating downward and keep the toggle block 3 at the position above the box body 2.

[0082] More specifically, the opening size of the second limiting groove 32 is greater than or equal to the first limiting member 4, so as to ensure that the first limiting member 4 can be accommodated therein.

[0083] Embodiment 3

[0084] The third embodiment of the present application is mainly different from the first and second embodiments in that the novel damper for the sliding door and window discloses two track structures for providing guiding and limiting functions for the movement track of the toggle block 3 in the box body 2 and the movement track of the box body 2 in the shell body 1.

[0085] As shown in one of the optional solutions of the embodiment, the toggle block 3 is provided with a first limiting groove 31 at one end thereof facing the second limiting member 5. When the limiting end 51 abuts against the toggle block 3, the limiting end 51 is clamped in the first limiting groove 31, thereby limiting the toggle block 3 from rotating downward around the first rotating shaft 6. In the technical solution of the embodiment, the first limiting groove 31 is a groove structure formed by being recessed inward of the toggle block 3 at the end thereof facing the limiting end 51, and the limiting end 51 is a relatively small protruding structure formed by protruding from the second limiting member 5 toward the toggle block 3. When the toggle block 3 rotates upward around the first rotating shaft 6 under the action of the damping toggle block a, the limiting end 51 is clamped in the first limiting groove 31, so that the toggle block 3 cooperates with the second limiting member 5 to block the toggle block 3 from rotating downward and keep the toggle block 3 at the position above the box body 2. Figure 1 Figure 4 ​​As shown, in an optional embodiment, the actuating block 3 is provided with a limiting shaft 33, and the housing 2 is provided with a second track 21. The limiting shaft 33 is slidably disposed in the second track 21, which provides guidance for the actuating block 3 to rotate around the first rotating shaft 6. In the technical solution of the embodiment, the second track 21 is specifically provided as symmetrical arc-shaped holes on both sides of the housing 2 in its width direction. The two ends of the limiting shaft 33 on the actuating block 3 are respectively inserted into the two arc-shaped holes and slidably disposed in the two arc-shaped holes, thereby ensuring that the movement trajectory of the actuating block 3 rotating around the first rotating shaft 6 does not deviate, that is, it plays a guiding and limiting role.

[0086] See Figure 1 and Figure 5 As shown, in another optional embodiment, the interior of the housing 1 is provided with a first track 11 extending along the length direction of the housing 1. The box 2 is slidably disposed on the first track 11, which provides guidance for the movement of the box 2 inside the housing 1. In this optional technical solution, the first track 11 is specifically a symmetrical track structure disposed on the two inner side walls of the housing 1. The box 2 is slidably disposed on these two track structures, thereby ensuring that the movement trajectory of the box 2 in a straight line along the length direction of the housing 1 does not deviate, that is, it plays a guiding and limiting role.

[0087] Example 4

[0088] See 3 and Figure 5 As shown, the main difference between the fourth embodiment of the present invention and embodiments 1, 2 and 3 is that the new type of damper for sliding doors and windows also includes a damping tube 9. The damping tube 9 is disposed inside the housing 1. There are two of each of the housing 2, the actuating block 3, the first limiting member 4 and the second limiting member 5. The two ends of the damping tube 9 are directly connected to the two actuating blocks 3, or indirectly connected to the two actuating blocks 3 through the two housings 2.

[0089] In the technical solution of this embodiment, the novel damper for sliding doors and windows is provided with two sets of housings 2, actuating blocks 3, a first limiting member 4, and a second limiting member 5, which can realize the bidirectional buffering and shock absorption function of the sliding door or window on both sides of the door frame. The specific principle is as follows:

[0090] like Figure 5As shown, when the door is closed to the left side door frame direction, the new damper for sliding door and window will move to a certain position along with the door body to the left, the push block 3 on the damper will encounter the block of the damping push block a, so that the push block 3 cannot continue to move relative to the damping push block a, and the shell 1 continues to move to the left side door frame direction under the action of inertia, at this time the damping pipe 9 can have damping buffer damping effect, so that the door body moving speed is not too fast, and slowly close to the left side door frame.

[0091] Similarly, when the door is closed to the right side door frame direction, the new damper for sliding door and window will move to a certain position along with the door body to the right, the push block 3 on the damper will encounter the block of the damping push block a, so that the push block 3 cannot continue to move relative to the damping push block a, and the shell 1 continues to move to the right side door frame direction under the action of inertia, at this time the damping pipe 9 can have damping buffer damping effect, so that the door body moving speed is not too fast, and slowly close to the right side door frame.

[0092] Therefore, the present application can realize the function of a bidirectional damping system by only setting two groups of box bodies 2, push blocks 3, first limiting pieces 4 and second limiting pieces 5, the structure design is simple and reasonable, and the cost is also more low.

[0093] In the process of using the sliding door damper, the damper will move to the door frame along with the door body when closing the door, when moving to a certain position, the push block 3 in the damper will encounter the block of the damping push block a, at this time the damping pipe 9 in the damper has damping buffer effect, so that the door body moving speed is not too fast, and slowly close to the door frame.

[0094] In the process of closing the door, due to the buffer effect of the damping pipe 9, the moving speed of the door body will be gradually weakened, but since the weights of different models of door bodies are different, when the door body is heavy or the moving speed of the door body is slow when closing the door, it will cause the door body to stop moving although the speed is weakened to zero, but the door body has not reached the door frame, which will cause the door to be not tightly closed, and seriously affect the user's experience.

[0095] Therefore, in order to solve the technical problem, the present embodiment discloses the following preferred scheme:

[0096] Referring to 3 and Figure 5As shown, the new damper for the sliding door window further comprises a second elastic member 10, which is arranged in the interior of the shell 1, two ends of the second elastic member 10 are connected with the two push blocks 3 respectively, and the second elastic member 10 and the damping tube 9 are arranged in parallel with each other. In the preferred technical solution, when the push block 3 is blocked by the damping push block a and the damping tube 9 plays a damping buffering and shock absorbing role, the second elastic member 10 can pull the door body to continue to move in the direction of the door frame under the action of its own tension, so as to avoid the situation that the door cannot be closed tightly.

[0097] More specifically, the second elastic member 10 described in the above embodiments adopts a detachable structure design, or the tension of the second elastic member 10 can be adjusted, so that the second elastic member 10 after being replaced or the second elastic member 10 after the tension is adjusted is adapted to the weight of the door body, further improving the adaptability of the new damper.

[0098] In another preferred solution of the embodiment, the second elastic member 10 is a tension spring, which is used to provide elastic forces in opposite directions for the two push blocks 3. Specifically, since the two ends of the tension spring are connected with the two push blocks 3 of the new damper respectively, when the door body is closed towards the left side, the tension spring provides an elastic tension for the push block 3 on the left side; when the door body is closed towards the right side, the tension spring provides an elastic tension for the push block 3 on the right side, finally achieving the effect of pulling the door body to continue to move.

[0099] More specifically, since the new damper is provided with left and right two push blocks 3, the tension spring does not need to be connected with the shell 1 directly or indirectly through other auxiliary connecting mechanisms, and the tension spring can play a role in pulling the door window to continue to move when the sliding door window moves to the left or to the right, avoiding that the door window is not closed tightly.

[0100] Embodiment 5

[0101] Referring to Figures 8 to 12 , the second limiting member 5 and the first limiting member 4 in the fifth embodiment of the application are different from the specific structures and arrangement modes in the first embodiment, the second embodiment, the third embodiment and the fourth embodiment, preferably, as shown in Figure 9 and Figure 10 , in the embodiment, the second limiting member 5 is fixedly arranged at one end of the push block 3 away from the first rotating shaft 6, and the first limiting member 4 is a limiting hole 41 arranged at the bottom of the shell;

[0102] In the technical solution of the embodiment, by arranging the first limiting member 4 and the limiting hole 41 in the interior of the shell 1, the switching of the two states of the push block 3 can be realized, specifically as follows:

[0103] ①、When the second limiting piece 5 is in the release position, the second limiting piece 5 is opposite to the limiting hole 41, the second limiting piece 5 can be inserted into the limiting hole 41 to make the toggle block 3 rotate and remain in the sunken position, at this time the toggle block 3 cannot move under the blocking action of the limiting hole 41, the box body 2 cannot move in the inside of the shell body 1, thereby avoiding the phenomenon of back movement of the toggle block 3;

[0104] ②、When the second limiting piece 5 is in the support position, the second limiting piece 5 abuts against the bottom of the shell body 1, the toggle block 3 remains in the upper position under the action of the second limiting piece 5, and cannot rotate downward, the second limiting piece 5 and the toggle block 3 can slide synchronously relative to the shell body 1, so that the box body 2 recovers to the movable state in the inside of the shell body 1.

[0105] In the embodiment, the working process and working principle of the novel damper for sliding door and window are as follows:

[0106] a、Before the door closing operation, referring to the first figure shown in Figure 11 , the initial state of the novel damper for sliding door and window is that the box body 2 is arranged close to the end of the shell body 1, and the second limiting piece 5 is inserted into the limiting hole 41 to keep the toggle block 3 in the sunken position, and the toggle block 3 cannot back move under the action of the tension spring.

[0107] b、When the door closing operation is performed, referring to the second figure shown in Figure 11 , the novel damper for sliding door and window moves along with the door body to the side of the door frame, that is, moves to the left in the figure, the toggle block 3 and the damping toggle block a (the damping toggle block a is fixed on the guide rail) are in contact, and move to the left end of the shell body 1 under the action of the damping toggle block a, at this time the damping pipe 9 connected with the toggle block 3 plays a buffering and damping role, at the same time the toggle block 3 rotates upward to the upper position around the first rotating shaft 6, the second limiting piece 5 fixed on the toggle block 3 also rotates upward around the first rotating shaft 6, the second limiting piece 5 can abut against the bottom of the shell body 1 after moving out of the limiting hole 41, the toggle block 3 cannot rotate downward under the action of the second limiting piece 5, thereby keeping the toggle block 3 in the upper position of the box body 2, and the second limiting piece 5 and the toggle block 3 can slide synchronously relative to the shell body 1.

[0108] c、When the door body is completely closed, the box body 2 slides to the middle part of the shell body 1, the damping toggle block a is clamped on the top of the toggle block 3, the box body 2 is fixed at this position of the shell body 1, and the toggle block 3 remains in the upper position of the box body 2.

[0109] d、When the door opening operation is performed, referring to Figure 12As shown in the two drawings, the new damper for sliding door and window moves along with the door body moving away from the door frame side, i.e. moving to the right in the drawing, the pushing block 3 moves to the left end of the shell 1 under the action of the damping pushing block a, when the box 2 moves to the end of the shell 1, the second limiting piece 5 is opposite to the limiting hole 41, the second limiting piece 5 removes the rotation restriction of the pushing block 3, the pushing block 3 rotates downward to the sunken position under the action of gravity after losing the action force of the second limiting piece 5, the second limiting piece 5 is inserted into the limiting hole 41, at this time, the pushing block 3 can be prevented from returning under the action of the tension spring 10 and returning to the initial state under the blocking and limiting action of the limiting hole 41.

[0110] Preferably, in the embodiment, in order to improve the structural strength and reduce the production cost, the second limiting piece and the pushing block are integrally formed. Certainly, in some other embodiments, the second limiting piece and the pushing block can also be connected by screws or welding rods, etc., and can be selected according to actual needs.

[0111] Preferably, in the embodiment, in order to enable the second limiting piece 5 to move relative to the limiting hole 41 smoothly, the limiting hole 41 is a waist-shaped hole; certainly, in some other embodiments, the limiting hole 41 can also be a round hole or a square hole, etc., and can be selected according to actual needs.

[0112] In summary, the new damper for sliding door and window provided by the application does not need to open a guide groove on the shell 1, so other high-strength and high-performance materials other than sheet metal parts can be used as the shell 1 material, the overall structural strength is high, the stability is good, and the shell 1 is prevented from being deformed in a long-term use. Further, since the guide block and the guide groove are not needed, the shell 1 can be integrally processed in the production process, the assembly process of the damper of the application can be greatly simplified, the shell 1 is not prone to being scrapped in the assembly process, and the integrally processed shell 1 has higher structural strength and is further prevented from being deformed in a long-term use.

[0113] And, the new damper for sliding door and window provided by the present application sets the first limiting piece 4 and the second limiting piece 5 in the inside of the shell 1, when the second limiting piece 5 removes the rotation restriction on the driving block 3, the driving block 3 rotates downward (i.e. sinks) with the first rotation shaft 6 as the center under the action of gravity, the first limiting piece 4 set in the inside of the shell 1 can keep the driving block 3 in the sinking position, thereby avoiding the back-moving phenomenon of the driving block 3 under the action of the stretching spring, the structure design does not need to set the vertical corner section of the guide slot, thereby avoiding the technical problem that it is difficult to move the driving block 3 to the inside again due to the corner section being too close to the vertical, when the driving block 3 rotates upward with the first rotation shaft 6 as the center under the action of the damping driving block 3a, the first limiting piece 4 removes the movement restriction on the driving block 3, the second limiting piece 5 can move to the supporting position, under the supporting action of the second limiting piece 5, the driving block 3 can keep in the upper position and cannot rotate downward, so that the box body 2 restores to the movable state in the inside of the shell 1.

[0114] It is worth mentioning that the new damper of the present application can be applied to sliding doors, sliding windows or other sliding type door and window products, in order to avoid redundancy, in the above four embodiments, the terms such as "door body" and "door leaf" are used to refer to the door body or window body structure of various sliding type door and window products.

[0115] The technical means disclosed in the present application scheme is not limited to the technical means disclosed in the above embodiments, but also includes the technical solutions composed of any combination of the above technical features. It should be noted that for ordinary skilled persons in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, which are also considered within the scope of protection of the present application.
