Description

Technical Field

[0001] This utility model relates to the field of building materials, and in particular to a plastic body and profile, especially an anti-loosening plastic body and a profile using the anti-loosening plastic body. Background Technology

[0002] Doors and windows are categorized as enclosure components or partition components based on their location, each with different design requirements, including functions such as heat insulation, sound insulation, waterproofing, and fireproofing. Opening, closing, and opening at a certain angle all require a moving rod inside the window sash. A handle actuates the moving rod, controlling the linkage components within the window sash to open, close, and open the sash at a specific angle relative to the frame. Since the moving rod slides on a stationary rod, the stability of the stationary rod is crucial for the stable operation of the moving rod. However, in traditional window sashes, the stationary rod is directly bolted to the sash profile. The moving rod's frequent sliding on the stationary rod causes vibration, which in turn vibrates the countersunk screws. Over time, these screws loosen, leading to a loose stationary rod itself. This instability in the moving rod, and consequently, failure of the linkage components within the window sash, results in door and window malfunctions.

[0003] Chinese utility model patent CN 203050400 U discloses an inward-opening side-hung device for doors and windows. The device includes a side-hung buckle fixed to the window frame and having an open straight groove, a stationary rod fixed to the window sash, a movable rod driven by a transmission handle, a connecting rod, and a pull rod. One end of the pull rod has a buckle that engages with the open straight groove of the side-hung buckle. The other end of the pull rod is riveted to the stationary rod through a long slot through a first rivet. The movable rod is fixedly connected to one end of the connecting rod through a short slot through a second rivet, allowing the movable rod to slide along the short slot of the stationary rod. The other end of the connecting rod is connected to the middle of the pull rod through a third rivet. The pull rod has an inward-opening locking boss, and a locking groove with a shape and size adapted to the inward-opening locking boss is opened at the corresponding position on the connecting rod. The locking groove and the inward-opening locking boss engage to lock the movement of the pull rod. A shaped spring plate is also fixed to the back of the stationary rod. The shaped end of the shaped spring plate extends above the long slot of the stationary rod and can act on the first rivet, limiting the movement of the first rivet. After prolonged use, the stationary rod on this device may loosen, causing the moving rod to become unstable and affecting the operation of the window sash. Utility Model Content

[0004] This invention aims to overcome the shortcomings of the prior art by providing an anti-loosening plastic body that ensures the static rod remains stable for extended periods of use, and a profile using this anti-loosening plastic body. This satisfies the requirement that the static rod will not loosen during long-term use of the moving rod, thus ensuring the stable operation of the moving rod over a long period.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This anti-loosening plastic body includes a plastic body, and plastic clips are fixed on the left and right sides of the plastic body. The thickness of the two plastic clips is less than that of the plastic body. The function of the plastic body is to prevent the countersunk screw from loosening when it is driven into and out of the plastic body, through the squeezing force of the rubber. This ensures that the stationary rod will not loosen even after long-term use on the profile, and ensures that the moving rod can also maintain accurate and stable use after long-term use. The function of the plastic clips fixed on the left and right sides of the plastic body, with the thickness of the two plastic clips less than that of the plastic body, is to limit the plastic body in the slot, thereby facilitating subsequent screwing in and tightening of the screw.

[0006] Further improvements include ensuring the bottom surfaces of the two plastic clips are flush with the bottom surface of the plastic body. This flush alignment facilitates processing and use; simply align the bottom surfaces of the plastic body, and the two clips can be directly inserted into the slots.

[0007] Further improvements include a recessed first chip removal groove on the bottom surface of the plastic body. The purpose of this first chip removal groove is to trap the chips generated when the countersunk screw is used to tighten the excavating plastic body. This prevents the plastic body from being lifted up by chips during screw tightening, which would reduce the compressive force of the plastic body on the countersunk screw and thus decrease its anti-loosening effect.

[0008] Further improvements include a guide groove at the top center of the plastic body, running along its length. This guide groove guides the bottom end of the countersunk screw during the drilling process, facilitating its insertion into the plastic body and preventing the screw from failing to screw in after a long time, thus improving assembly efficiency.

[0009] Further improvements include: first rounded corners between the top surface of the plastic body and its left and right sides; second rounded corners between the top and bottom surfaces of the two plastic clips and their sides; and rounded transition rounded corners between the sides of the plastic body and the top surfaces of the two plastic clips. The purpose of the first and second rounded corners is to ensure smooth transitions at the edges of the anti-loosening plastic body, facilitating installation and preventing injury to workers during installation and handling. The rounded transition rounded corners significantly increase the strength between the plastic body and the plastic clips, preventing cracking.

[0010] This type of profile using anti-loosening plastic material includes a profile body with a pair of slots on the profile body that respectively mate with two plastic clips. The function of the profile body and the slots is to enable the anti-loosening plastic material to be securely installed.

[0011] Further improvements include the addition of a crossbeam fixed to the profile body, with threaded holes on the crossbeam. The purpose of the crossbeam and threaded holes is to allow the countersunk screws to be screwed into the plastic body and engage with the threaded holes, thereby locking the stationary rod in place to prevent loosening.

[0012] Further improvements include a recessed second chip removal notch at the top of the crossbeam. The purpose of this second chip removal notch is to increase the chip removal space. When the countersunk screw is used to tighten the excavation plastic body, chips are generated. These chips can be trapped in the second chip removal notch, preventing the plastic body from being lifted up during excavation due to the inability to remove chips. This would reduce the compressive force of the plastic body on the countersunk screw, thus reducing its anti-loosening effect.

[0013] The beneficial effects of this utility model are:

[0014] 1) The plastic body allows the countersunk screw to be driven into and out of the plastic body. The squeezing force of the rubber can prevent the countersunk screw from loosening, thus ensuring that the stationary rod will not loosen even after long-term use on the profile, and ensuring that the moving rod can also maintain accurate and stable use after long-term use;

[0015] 2) The slot and plastic clip can be used to install the plastic body, so that the plastic body will not come out of the slot. When the countersunk screw is driven into and out of the plastic body, the squeezing force of the rubber can play a role in preventing the countersunk screw from loosening. This ensures that the static rod will not loosen after long-term use on the window sash profile, and ensures that the moving rod can also maintain accurate and stable use after long-term use.

[0016] 3) The excavation guide groove can guide the excavation of the bottom end of the countersunk screw, making it easier for the countersunk screw to be excavated and screwed into the plastic body, avoiding the problem of not being able to screw it in for a long time, and improving assembly efficiency.

[0017] 4) The first chip removal recess allows for chip generation when the countersunk screw is used to tighten the excavation plastic body. These chips can be trapped in the first chip removal recess, preventing the plastic body from being lifted up by chips during the tightening process. This reduces the squeezing force of the plastic body on the countersunk screw, thus reducing the anti-loosening effect of the countersunk screw.

[0018] 5) The second chip removal recess increases the chip removal space. When the countersunk screw is used to turn the excavating plastic body, chips will be generated. These chips can be trapped in the second chip removal recess, preventing the plastic body from being lifted up due to the inability to remove chips during the turning of the countersunk screw. This reduces the squeezing force of the plastic body on the countersunk screw, thus reducing the anti-loosening effect of the countersunk screw. Attached Figure Description

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] Referring to the attached diagram: This anti-loosening plastic body includes a plastic body 1, and plastic clips 1-1 are fixed on the left and right sides of the plastic body 1. The thickness of the two plastic clips 1-1 is less than that of the plastic body 1.

[0027] The bottom surfaces of the two plastic blocks 1-1 are flush with the bottom surface of the plastic body 1.

[0028] The bottom surface of the plastic body 1 has a recessed chip removal groove 1-2.

[0029] The top center of the plastic body 1 has a tunneling guide groove 1-3 arranged along the length of the plastic body 1, and the cross section of the tunneling guide groove 1-3 is "V" shaped.

[0030] A first rounded corner 1a is provided between the top surface of the plastic body 1 and the left and right sides, a second rounded corner 1b is provided between the top and bottom surfaces of the two plastic blocks 1-1 and the sides, and an arc transition rounded corner 1c is provided between the two sides of the plastic body 1 and the top surface of the two plastic blocks 1-1.

[0031] This type of profile using anti-loosening plastic material includes a profile body 2, on which a pair of slots 2-1 are respectively opened to cooperate with two plastic clips 1-1.

[0032] A crossbeam 2-2 is fixed on the profile body 2, and a threaded hole 2-2a is opened on the crossbeam 2-2.

[0033] The top of the crossbeam 2-2 has a recessed second chip removal notch 2-2b.

[0034] The working principle of this utility model is as follows: First, the plastic body 1 is installed into the slot 2-1 using two plastic clips 1-1. Then, the stationary rod 3 is installed into the profile body 2. At this point, the movable rod 4 is already installed together with the stationary rod 3 and can slide on the stationary rod 3. Subsequently, a countersunk screw 5 is installed into the mounting hole of the stationary rod 3 and passes through the guide hole 4-1 of the movable rod 4. Then, the bottom tip of the countersunk screw 5 is guided by the digging guide groove 1-3 and digs into the plastic body 1, and then exits the plastic body 1 to... The threads at the threaded hole 2-2a are engaged, and the generated debris is discharged through the first chip removal recess 1-2 and the second chip removal recess 2-2b, thereby locking the stationary rod 2. Because the elasticity of the plastic body 1 squeezes the threads of the countersunk screw 5, it has the effect of preventing the countersunk screw 5 from rotating. Even after long-term use of the moving rod 4, the countersunk screw 5 will not loosen. It has the effect of preventing the operation of the door and window sash from loosening, and the window sash is stable after long-term use without causing the problem of failure to operate. It is worth promoting and applying.
