Description

Technical Field

[0001] The utility model relates to the technical field of door and window fittings, and particularly relates to a sliding and swinging door opener. Background Art

[0002] With the continuous growth of people's demand for home life, sliding and swinging doors, also known as PD doors, can not only achieve sliding semi-open doors and windows, but also achieve fully open doors and windows after swinging. It is suitable for floor-to-ceiling door places such as balconies, studies, and gardens, especially balconies with relatively small outdoor spaces. The application of three-panel sliding and swinging doors provides more choices for home sliding and swinging doors, making the entire decoration style transparent and bright, and more modern.

[0003] The sliding track of the sliding and swinging door and window includes two parts: one part is a fixed track fixed to the upper part of the door and window frame, and the other part is a moving track fixed to the top of the fixed door and window sash. When full opening is required, the sliding door and window sash needs to slide along the fixed track to the moving track, and then rotate outward after overlapping with the fixed door and window sash to open. Therefore, matching pulley holes need to be provided on both the fixed track and the moving track to achieve the swinging and sliding of the door and window. When the sliding door and window sash overlaps with the fixed door and window sash and then rotates outward to open, in order to prevent the sliding door and window sash from sliding out of the pulley hole of the moving track and causing a safety accident, a baffle is usually set in the pulley hole. When the door and window sash swings, the baffle extends to block the pulley hole, thereby preventing the sliding door and window sash from sliding out of the track. When the door and window sash slides, the baffle retracts to open the slideway of the pulley hole, realizing the connection between the fixed track and the moving track and enabling the sliding of the sliding door and window sash.

[0004] Since during the docking process of the fixed track and the moving track, the moving track rotates around the door axis and gradually rotates from the side of the fixed track to dock. Currently, the common method is to set a baffle on the moving track and a push block on the fixed track. During the docking process of the moving track and the fixed track, the push block pushes the baffle out of the pulley hole to realize the connection of the pulley holes of the fixed track and the moving track. Due to the limitations of this kind of structure, the current sliding and swinging doors can only swing in one direction, that is, only swing outward or inward, resulting in a single door and window opening method and inconvenient use.

[0005] The technical problem to be solved by the utility model is: how to solve the problem that the existing sliding and swinging doors can only swing in one direction. Content of the Utility Model

[0006] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a sliding and swinging door opener, which has the characteristics of simple and compact structure, convenient use, and can enable the door and window to slide and swing both inward and outward.

[0007] The technical solution adopted by the present utility model is as follows: A push-pull and flat-opening door opener, comprising a first main body and a second main body. A first slideway is provided on the first main body, and a second slideway corresponding to the first slideway is provided on the second main body. The opener further comprises an opening and closing mechanism for controlling the opening and closing of the first slideway;

[0008] The opening and closing mechanism comprises a sliding stopper and a trigger member mounted on the first main body. The sliding stopper comprises a first slider and a baffle. The first slider is slidably connected to the first main body. One end of the baffle is connected to the first slider, and the other end extends towards the first slideway. The trigger member comprises a second slider and a push rod. The second slider is slidably connected to the first main body, and the second slider is in transmission cooperation with the first slider. One end of the push rod is connected to the second slider, and the other end extends out of the first main body towards the second main body. A first elastic member is provided between the first slider and the first main body, and a second elastic member is provided between the second slider and the first main body;

[0009] When the first main body and the second main body are in contact with each other, the push rod is driven to retract, thereby driving the baffle to withdraw from the first slideway; when the first main body and the second main body are separated, the second elastic member drives the push rod to extend outwards, and the first elastic member drives the baffle to extend into the first slideway.

[0010] For the push-pull and flat-opening door opener of the present application, when the first main body and the second main body approach and contact each other, the push rod is driven to retract into the first main body. Then, the second slider drives the first slider to slide on the first main body, thereby driving the baffle to withdraw from the first slideway, so that the first slideway is communicated with the second slideway. At this time, the sliding door and window sash can slide in the slideway and is in a push-pull state; when the first main body and the second main body are separated, the first elastic member drives the baffle to extend into the first slideway, and the push rod is driven by the second elastic member to reset. At this time, the door and window sash can be opened inwards and outwards, and it can be prevented that the sliding door and window sash slides out of the slideway during the inward and outward opening process, ensuring safety;

[0011] Since the push rod retracts by the contact between the first main body and the second main body, thereby driving the baffle to withdraw from the first slideway, no matter whether the second main body approaches and contacts the first main body from the left side or the right side, the push rod can be retracted, that is, the movable door and window sash can be opened inwards and outwards, and the opening method is diversified. Moreover, the opener of the present application has a simple and compact structure and is convenient to use.

[0012] In some embodiments, the first slider and the second slider are in transmission cooperation through an inclined surface.

[0013] By adopting the above technical solution, through the transmission cooperation of the inclined surface, the direction of force transmission is changed, and the movement of the retraction of the push rod is changed into the movement required for the baffle to withdraw from the first slideway.

[0014] In some embodiments, a first guiding surface and a second guiding surface corresponding to the push rod are provided on the second body. One end of the first guiding surface is connected to the second guiding surface, and the other end extends towards the second slideway. The distance between the first guiding surface and the first body gradually decreases from the end close to the second slideway to the end close to the second guiding surface. The other end of the second guiding surface extends away from the second slideway, and the distance between the second guiding surface and the first body gradually increases from the end close to the first guiding surface to the end away from the first guiding surface.

[0015] With the above technical solution, by providing the first guiding surface and the second guiding surface, when the first body and the second body approach or separate from each other, the end of the push rod protruding from the first body will remain in contact with the first guiding surface or the second guiding surface, guiding the push rod to gradually retract or extend, which can prevent the push rod from getting stuck during the retraction process and causing damage to the doors and windows.

[0016] In some embodiments, the first guiding surface and the second guiding surface are connected through a positioning groove.

[0017] With the above technical solution, when the first body and the second body are correspondingly fitted, the push rod just falls into the positioning groove, which can improve the positioning accuracy of the first body and the second body.

[0018] In some embodiments, a balance assembly is further included. The balance assembly includes a balanced block and a balance groove that are inserted into each other;

[0019] The balanced block is arranged on one side of the first body close to the second body, and the balance groove is arranged on one side of the second body close to the first body; or

[0020] The balanced block is arranged on one side of the second body close to the first body, and the balance groove is arranged on one side of the first body close to the second body.

[0021] With the above technical solution, the cooperation between the balanced block and the balance groove can improve the accuracy when the first body and the second body are aligned, so that the docking accuracy of the first slideway and the second slideway is higher, and the movable door and window sash slides more smoothly; at the same time, in order to prevent the door and window sash from falling due to its own weight, the balance groove should be arranged in a way parallel or close to parallel to the horizontal plane.

[0022] In some embodiments, guiding heads are provided at both ends of the balanced block, and the width of the guiding head gradually decreases from the end close to the middle of the balanced block to the end.

[0023] With the above technical solution, by providing guiding heads at both ends of the balanced block, it is convenient for the balanced block and the balance groove to be better inserted when being inserted into each other, preventing the balanced block and the balance groove from not being able to be inserted due to a slight misalignment.

[0024] In some embodiments, an anti-disengagement mechanism is further included. The anti-disengagement mechanism includes an anti-disengagement part and an anti-disengagement groove that cooperate with each other. When the first main body and the second main body are attached to each other, the anti-disengagement part is stuck in the anti-disengagement groove. When an external force greater than a preset value is applied, the anti-disengagement part exits the anti-disengagement groove, and the first main body and the second main body are separated.

[0025] The anti-disengagement part is floatingly connected to the side of the first main body close to the first main body, and the anti-disengagement groove is provided on the side of the second main body close to the first main body; or

[0026] The anti-disengagement part is floatingly connected to the side of the second main body close to the first main body, and the anti-disengagement groove is provided on the side of the first main body close to the second main body.

[0027] With the above technical solution, through the cooperation of the anti-disengagement part and the anti-disengagement groove, it is possible to prevent the first main body and the second main body from being easily separated after being attached. Only when the applied external force is greater than the binding force between the anti-disengagement part and the anti-disengagement groove can the first main body and the second main body be separated, improving safety.

[0028] In some embodiments, the anti-disengagement part includes a clamping head, a third slider, and a third elastic member. A sliding cavity for the third slider to slide is provided on the second main body. One end of the clamping head is connected to the third slider, and the other end protrudes from the second main body toward the first main body. The third elastic member is arranged at one end of the third slider away from the clamping head and is used to drive the clamping head to protrude out of the second main body. The anti-disengagement groove is provided on the first main body and is arranged opposite to the clamping head.

[0029] With the above technical solution, when the first main body and the second main body are attached, the clamping head is stuck in the anti-disengagement groove. Under the action of the third elastic member, the clamping head remains in contact with the anti-disengagement groove. Only when the applied external force is greater than the restoring force exerted by the third elastic member on the clamping head can the first main body and the second main body be separated.

[0030] In some embodiments, the anti-disengagement part includes a clamping head, a third slider, a first magnetic member, and a second magnetic member. A sliding cavity for the third slider to slide is provided on the second main body. One end of the clamping head is connected to the third slider, and the other end protrudes from the second main body toward the first main body. The first magnetic member is built into the third slider. The anti-disengagement groove is provided on the first main body and is arranged opposite to the clamping head. The second magnetic member is arranged on the first main body, and the first magnetic member and the second magnetic member are magnetically attracted to each other.

[0031] With the above technical solution, when the first main body and the second main body are attached, the clamping head is stuck in the anti-disengagement groove. Under the magnetic attraction of the first magnetic member and the second magnetic member, the clamping head remains in contact with the anti-disengagement groove. Only when the applied external force is greater than the magnetic force of mutual attraction between the first magnetic member and the second magnetic member can the first main body and the second main body be separated.

[0032] In some embodiments, the anti-withdrawal member includes a detent ball, a third elastic member, and a plugging member. A sliding cavity for the detent ball to slide is provided on the second main body. The plugging member plugs the sliding cavity. Two ends of the third elastic member respectively abut against the detent ball and the plugging member. An anti-withdrawal groove is provided on the first main body, and the anti-withdrawal groove is disposed opposite to the detent ball.

[0033] With the above technical solution, when the first main body and the second main body are attached to each other, the detent ball is snapped into the anti-withdrawal groove. Under the action of the third elastic member, the detent ball remains in abutment with the anti-withdrawal groove. Only when the external force applied is greater than the resilience force exerted by the third elastic member on the detent ball can the first main body and the second main body be separated.

[0046] First embodiment:

[0047] Please refer to Figures 1 to 7, a sliding and flat-opening door opener 100 according to the first embodiment of the present utility model, includes a first main body 10 and a second main body 20. A first slideway 11 is provided on the first main body 10, and a second slideway 21 corresponding to the first slideway 11 is provided on the second main body 20. It further includes an opening and closing mechanism 30 for controlling the opening and closing of the first slideway 11; the opening and closing mechanism 30 includes a sliding stopper 31 and a trigger 32 installed on the first main body 10. The sliding stopper 31 includes a first slider 311 and a baffle 312. The first slider 311 is slidably connected to the first main body 10. One end of the baffle 312 is connected to the first slider 311, and the other end extends towards the first slideway 11. The trigger 32 includes a second slider 321 and a push rod 322. The second slider 321 is slidably connected to the first main body 10, and the second slider 321 is in transmission cooperation with the first slider 311. One end of the push rod 322 is connected to the second slider 321, and the other end extends out of the first main body 10 towards the second main body 20. A first elastic member 33 is provided between the first slider 311 and the first main body 10, and a second elastic member 34 is provided between the second slider 321 and the first main body 10; when the first main body 10 and the second main body 20 are in contact, it drives the push rod 322 to retract, thereby driving the baffle 312 to withdraw from the first slideway 11; when the first main body 10 and the second main body 20 are separated, the second elastic member 34 drives the push rod 322 to extend outwards, and the first elastic member 33 drives the baffle 312 to extend into the first slideway 11. The sliding and flat-opening door opener 100 of the present application has the characteristics of simple and compact structure, convenient use, and enabling the doors and windows to be both pushed and pulled and opened and closed inwards and outwards.

[0048] As Figure 3 shown in Figure 7 , in this embodiment, the first slider 311 and the second slider 321 are in transmission cooperation through an inclined plane. Specifically, a first inclined plane 313 is provided on the first slider 311, and a second inclined plane 323 cooperating with the first inclined plane 313 is provided on the second slider 321. Through the cooperation and transmission of the inclined planes, the direction of force transmission is changed, and the movement of the push rod 322 retracting is converted into the movement required for the baffle 312 to withdraw from the first slideway 11.

[0049] In other embodiments, the transmission between the first slider 311 and the second slider 321 can also be achieved through the cooperation of a rack and a worm; a flexible member can also be provided between the first slider 311 and the first main body 10, and the second slider 321 is pressed against the flexible member. When the push rod 322 retracts, it drives the flexible member to bend, thereby driving the baffle 312 to retract. When the push rod 322 extends, the flexible member is straightened under the action of the first elastic member 33.

[0050] An accommodation groove for providing an activity space for the first slider 311 and the second slider 321 is provided inside the first main body 10; further, in order to facilitate the installation of the sliding stopper 31 and the trigger 32, an installation insert is detachably connected to the first main body 10, and the installation insert and the first main body 10 cooperate to form the above-mentioned accommodation cavity.

[0051] Further, a first chute for defining the sliding trajectory of the baffle 312 and a second chute for restricting the sliding trajectory of the push rod 322 are further provided inside the first main body 10.

[0052] In this embodiment, both the first elastic member 33 and the second elastic member 34 are compression springs.

[0053] Please refer to Figure 4 and Figure 6 , a first guiding surface 35 and a second guiding surface 36 corresponding to the push rod 322 are provided on the second main body 20. One end of the first guiding surface 35 is connected to the second guiding surface 36, and the other end extends towards the second slideway 21. The distance between the first guiding surface 35 and the first main body 10 gradually decreases from the end close to the second slideway 21 to the end close to the second guiding surface 36. The other end of the second guiding surface 36 extends in a direction away from the second slideway 21, and the distance between the second guiding surface 36 and the first main body 10 gradually increases from the end close to the first guiding surface 35 towards the end away from the first guiding surface 35. By providing the first guiding surface 35 and the second guiding surface 36, when the first main body 10 and the second main body 20 approach or separate from each other, the end of the push rod 322 protruding from the first main body 10 will remain in contact with the first guiding surface 35 or the second guiding surface 36, guiding the push rod 322 to gradually retract or extend, which can prevent the push rod 322 from getting stuck during the retraction process and causing damage to the doors and windows.

[0054] Further, the first guiding surface 35 and the second guiding surface 36 are connected through a positioning groove 37. When the first main body 10 and the second main body 20 are correspondingly attached, the push rod 322 just falls into the positioning groove 37, which can improve the positioning accuracy of the first main body 10 and the second main body 20.

[0055] Preferably, in order to ensure the positioning effect, the shape of the top end of the push rod 322 should match the shape of the positioning groove 37, and when the first main body 10 and the second main body 20 are separated, the push rod 322 can be disengaged from the positioning groove 37. The shape of the top of the push rod 322 is preferably a protruding arc surface or an arrow shape, and the positioning groove 37 is a corresponding arc-shaped groove or a "V"-shaped groove. Such a setting can also reduce the resistance of the push rod 322 in contact with the first guiding surface 35 or the second guiding surface 36 and reduce friction.

[0056] In one embodiment, the sliding and flat-opening door opener 100 of the present application further includes a balance assembly 40, and the balance assembly 40 includes a pair of inserted balance blocks 41 and balance grooves 42;

[0057] The balance block 41 is arranged on the side of the first main body 10 close to the second main body 20, and the balance groove 42 is arranged on the side of the second main body 20 close to the first main body 10; or

[0058] The balance weight 41 is arranged on the side of the second main body 20 close to the first main body 10, and the balance groove 42 is arranged on the side of the first main body 10 close to the second main body 20.

[0059] The cooperation between the balance weight 41 and the balance groove 42 can improve the accuracy when the first main body 10 is aligned with the second main body 20, so that the docking accuracy between the first sliding groove 11 and the second sliding groove 21 is higher, and the sliding of the movable door and window sash is smoother. At the same time, in order to prevent the door and window sash from sagging due to its own weight, the balance groove 42 should be arranged in a way parallel or nearly parallel to the horizontal plane, that is, the length extension direction of the balance groove 42 is the same as the direction in which the first main body 10 and the second main body 20 are attached or separated.

[0060] In this embodiment, the first guiding surface 35, the second guiding surface 36 and the positioning groove 37 are arranged at the bottom of the balance groove 42, and the push rod 322 protrudes from the top of the balance weight 41, which can make the overall structure of the opener more compact. Of course, in other cases where there is more space, the balance groove 42 can also be separately arranged from the first guiding surface 35, the second guiding surface 36 and the positioning groove 37.

[0061] Preferably, guiding heads 411 are arranged at both ends of the balance weight 41, and the width of the guiding head 411 gradually decreases from the end close to the middle of the balance weight 41 to the end. By arranging the guiding heads 411 at both ends of the balance weight 41, it is convenient for the balance weight 41 to be better inserted into the balance groove 42 during insertion, and to prevent the balance weight 41 and the balance groove 42 from being unable to be inserted due to slight misalignment.

[0062] Furthermore, in order to prevent the balance weight 41 from interfering with the second main body 20, a clearance groove corresponding to the balance weight 41 is arranged on the side of the second main body 20 away from the balance groove 42.

[0063] As Figure 4 shown in Figure 6 order to improve the safety of the sliding and opening and closing door and window, and prevent the door and window sash from swinging open during the sliding process, the sliding and opening and closing device 100 of the sliding and opening and closing door of the present application further includes an anti-retreat mechanism 50, and the anti-retreat mechanism 50 includes an anti-retreat part 51 and an anti-retreat groove 52 that cooperate with each other; when the first main body 10 is attached to the second main body 20, the anti-retreat part 51 is stuck in the anti-retreat groove 52; when an external force greater than a preset value is applied, the anti-retreat part 51 exits the anti-retreat groove 52, and the first main body 10 is separated from the second main body 20.

[0064] The anti-retreat part 51 is floatingly connected to the side of the first main body 10 close to the first main body 10, and the anti-retreat groove 52 is arranged on the side of the second main body 20 close to the first main body 10; or

[0065] The anti-retreat part 51 is floatingly connected to the side of the second main body 20 close to the first main body 10, and the anti-retreat groove 52 is arranged on the side of the first main body 10 close to the second main body 20.

[0066] The cooperation between the anti-retreat member 51 and the anti-retreat groove 52 can prevent the first body 10 and the second body 20 from being easily separated after being fitted together. The first body 10 and the second body 20 can only be separated when the applied external force is greater than the binding force between the anti-retreat member 51 and the anti-retreat groove 52, thereby improving safety.

[0067] In this embodiment, the anti-recoil member 51 includes a clamping head 511, a third slider 512, and a third elastic member 513. A sliding cavity is defined on the second body 20 for the third slider 512 to slide. One end of the clamping head 511 is connected to the third slider 512, and the other end protrudes from the second body 20 toward the first body 10. The third elastic member 513 is disposed at the end of the third slider 512 away from the clamping head 511 and is used to drive the clamping head 511 out of the second body 20. The anti-recoil groove 52 is disposed on the first body 10, and is disposed opposite the clamping head 511. When the first body 10 and the second body 20 are in contact with each other, the clamping head 511 is engaged with the anti-recoil groove 52. Under the action of the third elastic member 513, the clamping head 511 and the anti-recoil groove 52 remain in contact. Only when the applied external force is greater than the rebound force exerted by the third elastic member 513 on the clamping head 511 can the first body 10 and the second body 20 be separated.

[0068] In this embodiment, the anti-recoil component 51 may also include a clamping head 511, a third slider 512, a first magnetic component 514 and a second magnetic component 515. A sliding cavity for the third slider 512 to slide is provided on the second body 20. One end of the clamping head 511 is connected to the third slider 512, and the other end is protruded from the second body 20 toward the direction of the first body 10. The first magnetic component 514 is built into the third slider 512. The anti-recoil groove 52 is provided on the first body 10. The anti-recoil groove 52 is arranged opposite to the clamping head 511. The second magnetic component 515 is provided on the first body 10. The first magnetic component 514 and the second magnetic component 515 are magnetically attracted to each other. Optionally, the first magnetic component 514 and the second magnetic component 515 can both be permanent magnets or electromagnets. Alternatively, one of the first magnetic component 514 and the second magnetic component 515 can be set as a permanent magnet or an electromagnet, and the other can be set as a metal block such as iron that can be attracted by a magnet. When the first body 10 and the second body 20 are fitted together, the clamp head 511 is inserted into the anti-retraction groove 52. Under the magnetic attraction of the first magnetic part 514 and the second magnetic part 515, the clamp head 511 and the anti-retraction groove 52 remain in contact. Only when the external force applied is greater than the magnetic force of mutual attraction between the first magnetic part 514 and the second magnetic part 515, the first body 10 and the second body 20 can be separated.

[0069] Preferably, in order to facilitate separation of the clamp head 511 from the anti-retraction groove 52, the shape of the clamp head 511 is preferably an arc-shaped convex head or an arrow, and the shape of the anti-retraction groove 52 is preferably a matching arc-shaped groove or a "V"-shaped groove.

[0070] The push-pull and flat-opening door opener 100 of the present application utilizes the first main body 10 and the second main body 20 to approach and fit with each other, thereby driving the push rod 322 to retract into the first main body 10. Furthermore, the second slider 321 drives the first slider 311 to slide on the first main body 10, thereby driving the baffle 312 to withdraw from the first slideway 11, enabling the first slideway 11 to communicate with the second slideway 21. At this time, the sliding door and window sash can slide within the slideway and is in a push-pull state; when the first main body 10 and the second main body 20 are separated, the first elastic member 33 drives the baffle 312 to extend into the first slideway 11, and the push rod 322 is driven by the second elastic member 34 to reset. At this time, the door and window sash can be opened inwards and outwards, and it can prevent the sliding door and window sash from sliding out of the slideway during the inward and outward opening process, ensuring safety; since the push rod 322 retracts by the approach and fit of the first main body 10 and the second main body 20, thereby driving the baffle 312 to withdraw from the first slideway 11, regardless of whether the second main body 20 approaches and fits from the left or right side of the first main body 10, the push rod 322 can be retracted, that is, the door and window sash can be opened inwards and outwards, with diverse opening methods. Moreover, the opener of the present application has a simple and compact structure and is convenient to use.

[0071] Second Embodiment:

[0072] As Figure 8 shown, it is the push-pull and flat-opening door opener 100 of the second embodiment of the present utility model. The structure of the opener in this embodiment is similar to that of the opener in the first embodiment. The difference lies in that the structure of the anti-withdrawal member 51 in this embodiment is different from that in the first embodiment. In this embodiment, the anti-withdrawal member 51 includes a clamping bead 516, a third elastic member 513, and a plugging member 517. A sliding cavity for the clamping bead 516 to slide is provided on the second main body 20. The plugging member 517 plugs the sliding cavity. The two ends of the third elastic member 513 respectively abut against the clamping bead 516 and the plugging member 517. The anti-withdrawal groove 52 is provided on the first main body 10 and is disposed opposite to the clamping bead 516. When the first main body 10 and the second main body 20 are fitted, the clamping bead 516 is snapped into the anti-withdrawal groove 52. Under the action of the third elastic member 513, the clamping bead 516 remains in abutment with the anti-withdrawal groove 52. Only when the applied external force is greater than the restoring force exerted by the third elastic member 513 on the clamping bead 516 can the first main body 10 and the second main body 20 be separated.

[0073] Furthermore, in this embodiment, the anti-withdrawal groove 52 is opened on the side surface of the balance block 41, and the clamping bead 516 is provided on the side surface of the balance block 41. Such a setting can also make the overall structure of the opener more compact. When there is sufficient space for the opener, the anti-withdrawal groove 52 and the balance block 41 can also be separately provided, or the clamping bead 516 can be set to be opposite to the top of the balance block 41.

[0074] Optionally, in other embodiments, the detent ball 516 can be transformed into a cylinder provided with a ball head or an arc head. The anti-withdrawal member 51 can also be directly set as a ball plunger screw.

[0075] Furthermore, the plugging member 517 is threadedly connected to the second body 20. According to requirements, the compression amount of the third elastic member 513 can be adjusted by adjusting the depth of the plugging member 517 screwed into the second body 20, so as to adjust the extrusion force exerted by the detent ball 516 on the anti-withdrawal groove 52.

[0076] Optionally, one or more of the above anti-withdrawal members 51 can be used in combination.

[0077] Finally, it should be noted that the above are only the preferred examples of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
