Description
Technical Field
[0001] The utility model relates to the technical field of door and window accessories, in particular to a universal transmission rod structure. Background Art
[0002] The transmission rod is a physical transmission device on doors and windows, and plays a vital role in the door and window system. Whether it is when the casement doors and windows are using handle locks, or when the sliding door and window bar lock hooks are locked in the switch, the transmission rod can play a key role. Through it, users can easily control the opening, closing and tilting angle of the doors and windows. The transmission rod will also be installed and connected with door and window hardware accessories such as handles and locks, and the existing transmission rods are directly inserted into the hardware grooves on the end faces of the profiles. However, the shapes of the hardware grooves of the current profiles are not uniform. Common sliding door and window profiles have two types of hardware grooves: U-shaped grooves and C-shaped grooves. In order to adapt to these two groove types, the current transmission rod needs to be set to an adaptive shape, resulting in the current transmission rod being not very versatile, and a mounting hole for installing hardware accessories will be pre-opened at the fixed position of the transmission rod, resulting in a fixed and single installation position of the transmission rod, and poor flexibility in use.

DETAILED DESCRIPTION
[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] As shown in the accompanying drawings, the utility model discloses a universal transmission rod structure, including a transmission rod body 1 and a slide plate 2, wherein the transmission rod body 1 includes a connecting portion 10 located in the middle, and horn blocks 20 are symmetrically arranged on both sides of the connecting portion 10, and the horn blocks 20 are provided with a first recessed portion 201 for connecting to the C-shaped groove 30 and a second recessed portion 202 for connecting to the U-shaped groove 40 on a side away from the connecting portion 10, which can be adapted to different types of door and window profiles, and the transmission rod body 1 is located between the connecting portion 10 and the horn blocks 20. A slide groove 100 is formed between the slide plates 2, and a protrusion 21 slidably connected to the slide groove 100 is symmetrically arranged on one side of the slide plate 2. A locking piece 22 for fixedly connecting the transmission rod body 1 is arranged on the slide plate 2. The slide plate 2 is also provided with a connecting hole for connecting parts such as locking points. The connecting portion 10 is convex toward the front of the transmission rod body 1, that is, a recess 111 corresponding to the connecting portion 10 is formed on the back of the transmission rod body 1, and the recess 111 is used to accommodate the end of the locking piece 22 to prevent the locking piece 22 from protruding toward the back of the transmission rod body 1.
[0018] like Figure 4-5 As shown, it should be noted that the C-shaped groove 30 and the U-shaped groove 40 belong to European standard door and window profiles. The profile grooves of door and window profiles are now centered around these two types. The C-shaped groove 30 is characterized by a protrusion at the groove mouth, and the U-shaped groove 40 is characterized by a protrusion on the groove wall. The utility model provides a universal transmission rod structure, through the horn blocks 20 arranged on both sides of the transmission rod body 1, the horn blocks 20 are provided with a first recessed portion 201 and a second recessed portion 202, which are used to connect the C-shaped groove 30 or the U-shaped groove 40, the first recessed portion 201 is located at the top of the horn block 20, that is, corresponding to the protrusion of the C-shaped groove 30, when the transmission rod body 1 is installed in the C-shaped groove 30, Its protrusion is in contact with the first recessed portion 201, and the second recessed portion 202 is located at the bottom of the horn block 20, and the opening is facing the side away from the connecting portion 10. When the transmission rod body 1 is installed in the U-shaped groove 40, its protrusion is in contact with the second recessed portion 202, so that it can be suitable for profile hardware grooves circulating on the market. At the same time, the slide plate 2 can slide on the transmission rod, and after moving to the appropriate position, it is fixedly connected to the transmission rod through the locking piece 22. The position of the slide plate 2 on the transmission rod body 1 is not fixed and unique, and the transmission rod does not need to be pre-set with an installation hole, which improves the versatility and flexibility of the transmission rod structure and solves the problem of non-compatibility between current profiles.
[0019] In this embodiment, a screw hole 200 is provided on the skateboard 2, and the locking piece 22 is threadedly connected to the screw hole 200. The locking piece 22 is arranged on the screw hole 200. After the skateboard 2 is moved to an appropriate position, the locking piece 22 is screwed, and the locking piece 22 is moved downward along the thread. The locking piece 22 is used to pass through the transmission rod body 1 to achieve a fixed connection between the skateboard 2 and the transmission rod body 1. Specifically, a V-shaped groove 101 is provided in the middle of the front side of the connecting part 10. The length of the V-shaped groove 101 corresponds to the length of the transmission rod body 1, and the V-shaped groove 101 corresponds to the center of the locking piece 22. When the skateboard 2 slides to an appropriate position, the locking piece 22 is screwed, and the bottom of the locking piece 22 has a tip corresponding to the V-shaped groove 101. The locking piece 22 drills into the V-shaped groove 101 and passes through the transmission rod body 1, thereby achieving a fixed setting of the transmission rod body 1 and the skateboard 2.
[0020] like Figure 3 As shown, a connecting plate 50 is provided on the back of the connecting portion 10, and the horn block 20 is provided on the front of the connecting plate 50, so that a second recessed portion 202 is formed between the horn block 20 and the connecting plate 50, and the first recessed portion 201 is provided at the corners of the front and side surfaces of the horn block 20, and the second recessed portion 202 is used to accommodate the groove wall protrusion of the U-shaped groove 40, and the first recessed portion 201 is used to accommodate the groove mouth protrusion of the C-shaped groove 30, so that the transmission rod body 1 can be installed on the profile frame of the C-shaped groove 30, and can also be installed on the profile frame of the U-shaped groove 40, and the front side of the connecting portion 10 and the front side of the horn block 20 are arranged on the same plane, so as to ensure the installation state of the transmission rod body 1, so that it does not protrude from the profile groove, which is more neat and beautiful.
[0021] The above embodiments are preferred embodiments of the present utility model. All structures similar to the present utility model and equivalent changes made thereto should fall within the protection scope of the present utility model.
