DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] As shown in the accompanying drawings, the utility model is a transmission lock box that is easy to install. It is installed and used on door and window profiles. Generally, hardware slots 401 are provided on door and window profiles for installing door and window accessories. The installation of the transmission lock box now requires opening an installation opening 402 on the profile. When installing, the transmission box is placed in the installation opening 402. The transmission lock box of the present application comprises three parts: a bottom shell 1, a sliding plate 2 and a clip 3. The sliding plate 2 is slidably arranged between the bottom shell 1 and the clip 3. The bottom shell 1 and the clip 3 clamp the sliding plate 2 so that the sliding plate 2 It slides linearly between the bottom shell 1 and the clip 3. A sliding plate 21 protruding from the clip 3 is vertically provided in the middle of the sliding plate 2. The sliding plate 21 is longer than the connecting pin 20 and is used to connect the switch. The shift fork on the switch connects the sliding plate 21 and drives the sliding plate 21 to slide, so that the sliding plate 2 slides as a whole. Connecting pins 20 are provided at both ends of the sliding plate 2 for connecting other hardware accessories. Positioning members 31 for positioning and installation are symmetrically provided at both ends of the clip 3. The positioning and installation of the transmission lock box are realized by the two positioning members 31. Figure 3-4 As shown, the two positioning members 31 are in a "convex" shape, and both the positioning members 31 include a lower positioning piece 311 and an upper positioning piece 312. The lower positioning piece 311 is mainly used to cooperate with the hardware groove 401 for positioning the width of the transmission lock box and the profile hardware groove 401. The upper positioning piece 312 is mainly used to cooperate with the installation opening 402 for positioning the width of the transmission lock box and the installation opening 402. The transmission lock box only includes three parts: the bottom shell 1, the clip 3 and the sliding plate 2. It is more streamlined than the existing transmission lock box, and at the same time changes the movement mode of the existing transmission lock box, and changes the existing square shaft rotation movement mode to a fork-driven movement mode of the sliding plate 2 up and down.

[0019] The utility model provides a transmission lock box that is easy to install. The positioning and installation of the transmission lock box are achieved by two positioning pieces 31 provided on the clip 3. During installation, the lower positioning piece 311 is first positioned in conjunction with the profile hardware groove 401, and then the upper positioning piece 312 is positioned in conjunction with the installation opening 402, so that the transmission lock box can be quickly positioned and installed, thereby improving the installation efficiency and achieving the effect of convenient installation. At the same time, the transmission structure of the transmission lock box is simplified. Only the bottom shell 1 and the clip 3 provide space, so that the sliding plate 2 slides inside, and the sliding plate 2 is directly driven to move as a whole by the transmission rod 21. By reducing the probability of damage to the transmission structure, its durability is improved.

[0020] In this embodiment, a profile is also included, and a hardware groove 401 is provided on the profile. A mounting opening 402 is provided in the hardware groove 401. This belongs to the structure of the existing door and window profile and will not be further described. It should be noted that the width of the hardware groove 401 corresponds to the width of the lower positioning piece 311, and the length of the mounting opening 402 corresponds to the straight-line distance between the two positioning members 31. The width of the upper positioning piece 312 can also be designed to be the same as the width of the mounting opening 402. The transmission rod 2 The diameter of 1 is set to be smaller than the width of the upper positioning piece 312 to ensure that the transmission rod 21 can enter the installation opening 402. When installing, first place the transmission lock box corresponding to the hardware groove 401, put the positioning piece 31 into the hardware groove 401, and use the lower positioning piece 311 and the hardware groove 401 to achieve a limiting effect. The height of the lower positioning piece 311 can be further set to be equal to the groove depth of the hardware groove 401 to prevent the transmission lock box from deviating left and right, so that the transmission lock box slides straight along the hardware groove 401 to the installation opening 402. At this time, the first positioning piece 311 is The upper positioning piece 312 on the part 31 first enters the installation opening 402. Since the existing installation openings 402 are all opened in the hardware slot 401 and are on the same center line as the hardware slot 401, after the first upper positioning piece 312 enters the installation opening 402, continue to move the transmission lock box so that the other upper positioning piece 312 enters the installation opening 402. At this time, the positioning of the transmission lock box is completed. At this time, the transmission lock box can be installed and connected to the profile, and the transmission lock box can also be installed later. Just repeat the above action and use the positioning piece first. 31 cooperates with the hardware slot 401, moves the transmission lock box to the installation opening 402, and sequentially makes the upper positioning pieces 312 on the two positioning pieces 31 snap into the installation opening 402 to complete the positioning. At the same time, the area of ​​the profile cutting installation opening 402 can be reduced, reducing the damage to the integrity of the profile. In the past, the installation of the transmission lock box required opening a mounting opening 402 on the profile that was almost the same size as the shell. Now, only the size between the two positioning pieces is required, and the two positioning pieces are mainly used to provide enough space for the transmission rod to slide.

[0021] In this embodiment, the bottom shell 1 is provided with a groove 10, and the sliding plate 2 and the clip 3 are both arranged in the groove 10. The width of the sliding plate 2 and the clip 3 corresponds to the groove width of the groove 10. The bottom shell 1 is used to cover the clip 3 and the sliding plate 2, so that after the transmission lock box is installed, the bottom shell 1 and the profile can be used to hide the clip 3 and the sliding plate 2, which can better protect the transmission lock box. At the same time, the groove width of the groove 10 corresponds to the width of the clip 3 and the sliding plate 2, ensuring that the sliding plate 2 will not shift laterally during the sliding process. Further, arc notches can be set at both ends of the clip 3, and the arc notch and the connecting hole 100 have the same center.

[0022] In this embodiment, the clip 3 and the bottom shell 1 are fixedly connected by rivets, and the sliding plate 2 is clamped inside. The clip 3 and the bottom shell 1 can also be fixedly connected by other connecting parts such as screws. The reserved distance between the clip 3 and the bottom shell 1 can be further designed to be equal to the thickness of the sliding plate 2, thereby achieving a thinner transmission lock box structure and making the sliding plate 2 slide more smoothly.

[0023] In this embodiment, the bottom shell 1 is provided with two connecting holes 100, and the two connecting holes 100 are directly opposite to the two ends of the clip 3, and the sliding plate 2 is provided with a through slot 202 at the position corresponding to the connecting holes 100. Figure 1 and 3 As shown, screws or other connecting parts are driven into the two connecting holes 100 to connect the profiles. The screws are located at both ends of the clip 3 and can be used to support the clip 3 to prevent it from loosening. The through groove 202 is convenient for the screws to pass through and prevents the screws from limiting the sliding of the sliding plate 2.

[0024] In this embodiment, the bottom shell 1 and the clip 3 are both integrally formed structures, which are more convenient to form. The bottom shell 1 is folded, and the two ends of the clip 3 are cut into a "convex" shape and bent 90 degrees to form a positioning member 31. At the same time, the integrity is better and more durable.

[0025] The above embodiments are preferred embodiments of the present invention. All structures similar to those of the present invention and equivalent changes made thereto should fall within the scope of protection of the present invention.
