Description

Technical Field

[0001] The utility model relates to the technical field of door and window accessories, in particular to a transmission box. Background Art

[0002] The transmission box is a crucial component of door and window locking systems; the handle drives the transmission box, which in turn moves the associated locking points up and down, engaging the lock base to lock and open the door or window. The transmission box is fixed to the door or window profile, and the handle is locked to the transmission box with screws. Transmission boxes are commercially available with anti-skewing components. These components slide into the housing and directly engage the handle screw. When the handle screw is tightened, the anti-skewing component presses against the profile. The tension applied by the handle screw on the anti-skewing component is not applied to the housing, preventing deformation of the transmission box.

[0003] As the market becomes increasingly diverse, handle hole spacing is also trending towards greater diversity. To meet this market demand, some transmission boxes have innovated in design, featuring multiple sets of through-holes with varying hole spacings to achieve broad compatibility with handles of varying hole spacings. However, this design also presents a new challenge: traditional anti-skewing components are often only able to secure through-holes corresponding to a specific set of hole spacings on the transmission box, making them ineffective in fully utilizing their anti-skewing function when used with handles with non-predetermined hole spacings. Utility Model Content

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a transmission box to solve the problem that the anti-skewing component in the prior art can often only be fixed to through holes corresponding to a certain set of specific hole spacings on the transmission box, resulting in the inability to fully exert its anti-skewing function when facing handles with non-preset hole spacing models.

[0045] See also Figures 1 to 9 The embodiment of the present utility model discloses a transmission box, which includes: a box body 1 and an anti-skewing component 2, the box body 1 is provided with two first through holes 11 opened at a first preset hole distance and two second through holes 12 opened at a second preset hole distance, a slot 13 is provided between the adjacent first through holes 11 and the second through holes 12, and the anti-skewing component 2 is detachably connected to the slot 13; a threaded connection hole 221 is provided on the anti-skewing component 2, when the anti-skewing component 2 is inserted into the slot 13 at different angles, the threaded connection hole 221 coincides with the first through hole 11 and / or the second through hole 12, when the transmission box faces handles 7 with different hole distance models, it can be adapted through simple adaptive adjustment. Specifically, the anti-skewing component 2 is slidably inserted into the slot 13 along the axial direction of the threaded connection hole 221, and the anti-skewing component 2 can be completely disengaged from the slot 13. When the anti-skewing component 2 is completely disengaged from the slot 13, the angle of the anti-skewing component 2 can be adjusted and then reinserted into the slot 13, thereby changing the connection relationship between the threaded connection hole 221 provided thereon and the first through hole 11 and / or the second through hole 12. Preferably, the line connecting the two first through holes 11 coincides with the line connecting the two second through holes 12, and the slot 13 is provided at the midpoint of the line connecting the adjacent first through holes 11 and the second through holes 12. Preferably, the first preset hole distance is 20 mm, and the second preset hole distance is 43 mm. Preferably, the midpoint of the line connecting the two first through holes 11 coincides with the midpoint of the two second through holes 12.

[0046] It should be explained that the handle 7 includes a handle body and a handle base. The handle base is provided with two screw holes set at a first preset hole spacing or a second preset hole spacing. When the handle 7 needs to be installed on the transmission box, the screw holes on the handle base are aligned with the threaded connection holes 221 on the anti-skewing component 2 and the first through hole 11 or the second through hole 12 on the box body 1, and bolts are inserted to establish a stable connection. It should be noted that in this embodiment, two first through holes 11 and two second through holes 12 are provided, and the slots 13 are provided between the adjacent first through holes 11 and second through holes 12. In this embodiment, there are two slots 13, and correspondingly, there are also two anti-skewing components 2. The two anti-skewing components 2 correspond to the two screw holes on the handle base respectively. Compared with the integrated anti-skewing component 2 of the prior art, the connecting structure between the two anti-skewing components 2 is omitted, thereby reducing the overall weight of the transmission box.

[0047] Preferably, the anti-skewing component 2 is made of stainless steel. It should be explained that the existing anti-skewing component 2 is mostly made of die-cast zinc alloy, which has high processing costs and poor weather resistance, and is not suitable for the climate in the north and south. When the user uses the same zinc alloy anti-skewing component 2 multiple times, the anti-skewing component 2 is easily damaged, causing the handle 7 to shake when the user adjusts it. Therefore, the anti-skewing component 2 in this embodiment is designed to be made of stainless steel, which has outstanding advantages in cost, strength, weather resistance, scope of application, environmental protection, safety, and humanization.

[0048] Furthermore, a mounting cavity is provided in the box body 1, and a support guide 3 is provided in the mounting cavity. The support guide 3 is located on the side of the slot 13 leading to the mounting cavity, and an insertion gap 31 corresponding to the slot 13 is provided on the support guide 3. Optionally, the support guide 3 can be a structure integrally formed with the box body 1, or a component designed separately and assembled in the box body 1. Preferably, the inner side wall of the insertion gap 31 is provided with a friction surface, and the friction surface is used to provide friction resistance for the inserted guide plate 21. In this embodiment, the material of the support guide 3 can be a silicone material or a rubber material, which provides friction resistance for the inserted guide plate 21 due to the characteristics of its own material. Preferably, the width of the insertion gap 31 is less than the thickness of the guide plate 21 of the anti-skewing component 2. When the guide plate 21 of the anti-skewing component 2 is inserted into the slot 13, it will pass into the insertion gap 31, and the insertion gap 31 provides friction resistance for the movement of the guide plate 21 in or out of the slot 13, so that the cooperation between the anti-skewing component 2 and the box body 1 is more stable. It should be explained that during transportation, the transmission box in this embodiment is generally in a state where the guide plate 21 of the anti-skewing component 2 is fully inserted into the slot 13. In this state, the friction provided by the support guide 3 to the anti-skewing component 2 can effectively prevent the anti-skewing component 2 from separating from the box body 1, thereby ensuring the integrity of the product. Optionally, the support guide 3 is further provided with connecting holes corresponding to the first through hole 11 and the second through hole 12. Optionally, the box body 1 is formed by assembling a front shell 15 and a rear shell 16, and both the front shell 15 and the rear shell 16 are provided with slots for the connector to penetrate or pass through, and the support guide 3 is provided with avoidance holes corresponding to the slots.

[0049] Furthermore, the anti-skewing component 2 includes a guide plate 21 and a screw-on plate 22 extending from one end of the guide plate 21. The guide plate 21 is detachably and slidably inserted into the slot 13, and a threaded connection hole 221 is provided on the screw-on plate 22. Specifically, the relative rotational freedom between the guide plate 21 and the slot 13 is zero, that is, the guide plate 21 and the slot 13 cannot rotate when they are plugged in. This means that when the guide plate 21 is inserted into the slot 13, the relative positional relationship between the anti-skewing component 2 and the first through hole 11 and the second through hole 12 is fixed. Only when the guide plate 21 is disengaged from the slot 13 can the angle of the anti-skewing component 2 be adjusted to change the relative positional relationship between the anti-skewing component 2 and the first through hole 11 and the second through hole 12. Preferably, the guide plate 21 cannot rotate within the slot 13. However, before the guide plate 21 enters the slot 13, there are two selectable insertion angles. By adjusting the angles, the threaded connection hole 221 can be aligned with the first through hole 11 and / or the second through hole 12. Optionally, the opening of the slot 13 can be rectangular, diamond-shaped, elliptical, or other irregular shapes. Preferably, the guide plate 21 is perpendicular to the screw plate 22, and the axis of the threaded connection hole 221 is perpendicular to the screw plate 22.

[0050] Optionally, an internal threaded column 222 is provided on the side of the screw-on plate 22 facing the guide plate 21, and the threaded connection hole 221 is opened along the axial direction of the internal threaded column 222. When the anti-skewing component 2 is inserted into the slot 13 and gradually goes deeper, the internal threaded column 222 will gradually approach the first through hole 11 and / or the second through hole 12, and the outer diameter of the internal threaded column 222 is smaller than the diameter of the first through hole 11 and the second through hole 12. When the screw-on plate 22 is in contact with the outer surface of the box body 1 on the side facing the guide plate 21, the internal threaded column 222 is inserted into the first through hole 11 and / or the second through hole 12.

[0051] In one embodiment, if Figure 8 As shown, the guide plate 21 and the screw plate 22 form an L-shaped anti-skewing component 2, and the screw plate 22 is provided with a threaded connection hole 221. In this embodiment, the shortest distance from the threaded connection hole 221 to the guide plate 21 is equal to the shortest distance from the first through hole 11 to the slot 13, and the shortest distance from the second through hole 12 to the slot 13. Therefore, when the guide plate 21 is inserted into the slot 13, regardless of whether the screw plate 22 is facing the first through hole 11 or the second through hole 12, the threaded connection hole 221 thereon can overlap with the first through hole 11 or the second through hole 12. It should be explained that in this embodiment, the anti-skewing component 2 is L-shaped, so the threaded connection hole 221 on the screw plate 22 can only overlap with one of the first through hole 11 and the second through hole 12 at a time. If it is necessary to change the overlap of the threaded connection hole 221, the guide plate 21 of the anti-skewing component 2 can be pulled out of the slot 13, reversed, and reinserted.

[0052] In another embodiment, Figure 9 As shown, the guide plate 21 and the screw plate 22 constitute a T-shaped anti-skewing component 2, and the screw plate 22 is provided with two threaded connection holes 221, and the two threaded connection holes 221 are equidistantly arranged on both sides of the guide plate 21. Specifically, the two threaded connection holes 221 provided on the screw plate 22 are respectively a first screw hole 2211 and a second screw hole 2212 of different hole types. Optionally, the first screw hole 2211 and the second screw hole 2212 are screw holes corresponding to M4 screws and M5 screws, respectively. In this embodiment, the shortest distance from the first screw hole 2211 to the guide plate 21, the shortest distance from the second screw hole 2212 to the guide plate 21, the shortest distance from the first through hole 11 to the slot 13, and the shortest distance from the second through hole 12 to the slot 13 are the same. It can be understood that the anti-skewing component 2 in this embodiment is T-shaped and the first screw hole 2211 and the second screw hole 2212 provided thereon are screw holes of different hole types, so that in addition to being able to adapt to the two types of handles 7 with the first preset hole spacing and the second preset hole spacing, the anti-skewing component 2 in this embodiment can also be adapted to the two types of handle screws and handles 7 of M4 and M5.

[0053] See also Figure 1 、 Figure 2 as well as Figures 10 to 16 The transmission box in this embodiment further includes a rotating wheel 4 and a transmission bar 5. A mounting cavity is provided within the box body 1. The rotating wheel 4 is rotatably disposed within the mounting cavity, and the transmission bar 5 is translationally disposed outside the mounting cavity. The box body 1 also includes a transmission hole 14 extending inwardly toward the rotating wheel 4. The rotating wheel 4 is transmission-connected to the transmission bar 5. When the rotating wheel 4 rotates under control, it drives the transmission bar 5 in a linear reciprocating motion. Specifically, the transmission box further includes a transmission plate 6, which is connected to the rotating wheel 4 and the transmission bar 5, respectively. The transmission plate 6 is translationally disposed within the mounting cavity, and the translation direction of the transmission plate 6 is parallel to the translation direction of the transmission bar 5.

[0054] Specifically, the rotating wheel 4 is provided with a transmission shaft hole 41 and a transmission connection portion 42. The transmission shaft hole 41 corresponds to the transmission hole 14. When the rotating wheel 4 is controlled to rotate, the transmission connection portion 42 rotates about the transmission shaft hole 41. The transmission plate 6 has a transmission slot 61, the length of which is perpendicular to the translational direction of the transmission bar 5. The transmission connection portion 42 is slidably connected to the transmission slot 61. It should be explained that the transmission shaft hole 41 is used to connect with the transmission shaft of the handle 7. Therefore, when the handle 7 rotates, the rotating wheel 4 will rotate synchronously with the handle 7 with the transmission shaft hole 41 as the rotation center. It is understood that when the wheel 4 rotates, the circumferential motion of the transmission connection portion 42 around the transmission shaft hole 41 can be decomposed into a sub-motion perpendicular to the translational direction of the transmission bar 5 and a sub-motion parallel to the translational direction of the transmission bar 5. The sub-motion of the transmission connection portion 42 perpendicular to the direction of the transmission bar 5 causes the transmission connection portion 42 to slide relative to the transmission groove 61, and will not cause the transmission plate 6 to move perpendicular to the translational direction of the transmission bar 5; the sub-motion of the transmission connection portion 42 parallel to the translational direction of the transmission bar 5 will cause the transmission plate 6 to move parallel to the translational direction of the transmission bar 5. Furthermore, a first limiting structure is provided on the box body 1. When the wheel 4 reaches the extreme position, the transmission plate 6 and the transmission bar 5 are simultaneously limited by the first limiting structure on the box body 1. Optionally, the transmission connection portion 42 is a raised structure that passes through the transmission groove 61 and can slide relative to each other along the length of the transmission groove 61. Optionally, the transmission shaft hole 41 is a square hole.

[0055] The transmission plate 6 is detachably connected to the transmission bar 5. Optionally, the connection between the transmission plate 6 and the transmission bar 5 can be detachably connected via bolts or a snap-fit ​​mechanism. It is understood that due to the detachable connection between the transmission plate 6 and the transmission bar 5, the transmission box in this embodiment can be disassembled into smaller modules during transportation. Users can choose to assemble the box before transportation and install it on the door and window profiles upon arrival, simplifying on-site installation work. Alternatively, the box can be assembled after arrival at the destination for easier transportation.

[0056] Specifically, in this embodiment, the transmission plate 6 is provided with a slot 62, and the transmission bar 5 is provided with a side-sliding hook 51, which engages with the slot 62. During assembly of the transmission box in this embodiment, the transmission connection portion 42 of the rotating wheel 4 is first inserted into the transmission slot 61 of the transmission plate 6. Then, after aligning the side-sliding hook 51 on the transmission bar 5 with the slot 62 on the transmission plate 6, force is applied to the side of the transmission bar 5 to engage the side-sliding hook 51 with the slot 62. This allows the transmission plate 6 and the transmission bar 5 to engage through the slot 62 and the side-sliding hook 51. When the transmission plate 6 is subjected to an upward pulling force, the slot 62 engages the side-sliding hook 51, preventing the transmission plate 6 from moving upward. The transmission box in this embodiment provides more stable transmission, simpler assembly, and longer life. Optionally, two slots 62 are provided on the transmission plate 6, and two corresponding side-sliding hooks 51 are provided on the transmission bar 5. During assembly, the two side-sliding hooks 51 need to be engaged with the two slots 62, respectively. Preferably, the opening directions of the two slots 62 are opposite and symmetrical, so that after the slots 62 of the transmission plate 6 are engaged with the side-sliding hooks 51 of the transmission bar 5, the transmission plate 6 and the transmission bar 5 are relatively fixed in the translation direction of the transmission bar 5 and in a direction perpendicular to the translation direction of the transmission bar 5. Optionally, one slot 62 can also be provided on the transmission plate 6, and one corresponding side-sliding hook 51 is provided on the transmission bar 5. During assembly, only one side-sliding hook 51 needs to be engaged with the slot 62.

[0057] Compared with the prior art, the transmission box of the present invention sets the slot between the adjacent first through hole and the second through hole, and the anti-skew component can be inserted into the slot at different angles to select the threaded connection hole to coincide with the first through hole and / or the second through hole. Therefore, when the transmission box faces handles with different hole pitch models, it can be adapted through simple adaptive adjustment.

[0058] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
