Description

Technical Field

[0001] The invention relates to the technical field of door and window installation, in particular to an energy-saving door and window installation and fastening device. Background Art

[0002] Energy-saving doors and windows are designed to increase the lighting and ventilation area or to express the characteristics of modern buildings. Energy-saving doors and windows will improve the optical properties, thermal properties and sealing of the materials, and improve the structure of doors and windows to achieve the expected results. Energy-saving doors and windows should be considered from the following aspects: door and window materials, glass, and door and window energy saving is overall energy saving. In short, the energy saving of doors and windows depends not only on the material, but also on the glass, and more on the craftsmanship of doors and windows.

[0003] However, when installing energy-saving doors and windows, most of the traditional methods, after the doors and windows are snapped into place with the wall frames, are to support and adjust the angle of the doors and windows by using wood chips. This is very cumbersome to operate due to the heavy doors and windows, and the wood chips have poor stability when placed, which can easily cause them to loosen, making the installation of the doors and windows unstable. At the same time, after the doors and windows are installed, they are directly fixed to the wall with bolts, and there is a lack of interference components between the bolts and the doors and windows. Loose bolts can easily cause the doors and windows to shake against the wall, which can easily cause safety accidents. Summary of the invention

[0004] In view of the problems in the prior art, the present invention provides an energy-saving door and window installation and fastening device.

The plurality of mounting grooves are respectively engaged with mounting plates, and a connecting groove is provided on the mounting plate. A driving plate is slidably connected to the inner side of one end of the mounting plate, and two symmetrical extrusion plates are provided inside the connecting groove, and a support plate is rotatably connected between the two extrusion plates, wherein one end of one of the extrusion plates is rotatably connected to the inner side of the connecting groove, and one end of the other extrusion plate is rotatably connected to the driving plate.

[0007] Specifically, the driving mechanism includes a movable slot provided on the driving plate. A rack is installed inside the movable slot and fixedly connected to the driving plate. A gear is provided inside the movable slot and meshes with the rack. A driving rod is vertically rotatably connected to the mounting plate and extends into the movable slot. The gear is fixedly connected to the driving rod, and the top of the driving rod is of an internal hexagonal structure.

[0008] Specifically, the protection mechanism includes a helical gear disk installed on the driving rod. The helical gear disk is rotatably connected to the inner side of the mounting plate through the driving rod. A clamping block is installed on the inner side of the mounting plate and slidably connected to the inside of the mounting plate through a contact spring. One end of the clamping block abuts against the outer side of the helical gear disk, and the pointed teeth at one end of the clamping block are in the opposite direction to the pointed teeth of the helical gear disk.

[0009] Specifically, the extrusion mechanism includes a return spring installed inside the driving rod. The helical gear disk is slidably connected to the driving rod through the return spring. A pressing rod is slidably connected to the driving rod and extends into the driving rod to connect with the center of the helical gear disk.

[0010] Specifically, a guide rod is installed at the center of the bottom of the helical gear disk and penetrates through the return spring to be slidably connected to the inside of the driving rod.

[0011] Specifically, the fixing mechanism includes grooves provided on both sides of the mounting plate. Symmetrical pressing blocks are installed inside the side wall of the door and window body, and one side of the pressing block extends into the installation groove. One side of the pressing block abuts against the inside of the groove, and a screw is threadedly connected to the side wall of the door and window body. One end of the screw is rotatably connected to the inside of the pressing block.

[0012] Specifically, the stabilizing mechanism includes fixing grooves provided on the door and window body. A sliding sleeve is provided inside the fixing grooves. The sliding sleeve is of an internal cylindrical "T" - shaped structure and is slidably connected to the inside of the fixing grooves through a compression spring.

[0013] The beneficial effects of the present invention are:

[0014] (1) The energy-saving door and window installation and fastening device described in the present invention, through the installation of multiple interference mechanisms, the interference mechanisms are operated under the cooperation of the driving mechanism, so that the interference mechanisms can interfere with the wall, thereby facilitating the adjustment and support of the angle of the door and window body, so that the door and window body can be installed stably and firmly, that is: through the action of multiple installation grooves, it is convenient to install multiple installation plates, by driving and controlling the driving plate, the driving plate drives one of the extrusion plates to squeeze the support plate, and with the cooperation of another extrusion plate, the support plate is slid out and supported by the wall, so that the door and window body is stably engaged on the wall, and by controlling the sliding position of the driving plate, the supporting position of the support plate is adjusted, so that the installation angle of the door and window body is flat and stable, and the adjustment is easier and more convenient, thereby improving the overall installation efficiency, and through the installation of the driving rod, it is convenient to control the gear connection, and through the driving control of the driving rod by the wrench, the gear drives the rack, and the rack drives the driving plate to slide and control the inside of the installation plate, thereby realizing the control and adjustment of the extrusion plate, and the operation is more convenient and labor-saving.

[0015] (2) The energy-saving door and window installation and fastening device described in the present invention is conducive to the unidirectional rotation of the driving mechanism under the action of the protective mechanism, thereby preventing the interference mechanism from loosening, and is conducive to the resetting of the protective mechanism under the action of the squeezing mechanism, which is convenient for the driving mechanism to rotate and adjust freely, that is: when the driving rod is driven and controlled, the driving rod drives the bevel gear plate to rotate, and when the bevel gear plate rotates, it resists the card block, so that the card block can shrink, which is convenient for the rotation of the bevel gear plate. Because the sharp teeth at one end of the card block are in opposite directions to the sharp teeth of the bevel gear plate, after the bevel gear plate rotates, the card block resists the bevel gear plate and cannot rotate in the opposite direction, which is conducive to the stability of the gear after rotation. The helical gear plate is easily loosened and supported by the support plate, so that the support plate is stable and firm, and the stability of the door and window body is improved. The installation of the reset spring is conducive to the sliding connection between the bevel gear plate and the driving rod. Under the resistance of the reset spring, the bevel gear plate is engaged with the card block to realize one-way rotation. By squeezing the pressure rod with a wrench, the pressure rod drives the bevel gear plate to get rid of the action of the reset spring and slide down, so that the bevel gear plate is separated from the card block, which facilitates the free rotation of the driving rod and realizes the reset of the support plate. Under the action of the guide rod, the bevel gear plate slides smoothly and stably on the driving rod, and the bevel gear plate will not be deflected and unable to resist the card block to realize one-way rotation control.

[0016] (3) The energy-saving door and window installation and fastening device described in the present invention is conducive to the detachable installation of the interference mechanism and the door and window body through the action of the fixing mechanism, which is more convenient to operate and is conducive to subsequent replacement and maintenance. The interference of the bolts on the door and window body is stable under the action of the stabilizing mechanism, and the bolts will not loosen and cause the door and window body to loosen, that is, after the mounting plate is engaged with the inside of the mounting groove, the driving control of the screw rod by the wrench drives the screw rod to drive the pressure block under the action of the thread, and the pressure block interferes with the inside of the groove of the side wall of the mounting plate, so that the mounting plate is firmly and stably connected inside the mounting groove. By rotating the screw rod in the opposite direction, the pressure block is separated from the groove, which is convenient for disassembly and assembly of the mounting plate. The action of the fixing groove facilitates the insertion of the bolts, and the door and window body is fixed to the wall by the bolts. Through the installation of the sliding sleeve, the sliding sleeve is locally retracted under the action of the compression spring. After the bolt penetrates into the inside of the sliding sleeve, the bolt interferes with the sliding sleeve. Under the action of the compression spring, the sliding sleeve always interferes tightly with the door and window body, so that the door and window body and the wall are firmly and stably installed.

DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0029] like Figures 1 - 9 As shown, an energy-saving door and window installation and fastening device described in the present invention includes a door and window body 1, a plurality of interference mechanisms 2 are installed on the door and window body 1, a driving mechanism 3 is installed on the interference mechanism 2, a protective mechanism 5 is installed on the driving mechanism 3, an extrusion mechanism 6 is installed on the driving mechanism 3, a plurality of fixing mechanisms 4 are installed on the door and window body 1, and a plurality of stabilizing mechanisms 7 are installed on the door and window body 1.

[0030] Specifically, the abutment mechanism 2 includes a mounting groove 202, and a plurality of mounting grooves 202 are respectively provided on the outer side of the door and window body 1, and the mounting grooves 202 are of a "convex"-shaped structure. The plurality of mounting grooves 202 are respectively connected with mounting plates 201 in a snap-fitting manner, and the mounting plate 201 is provided with a connecting groove 206, and a driving plate 205 is slidably connected to the inner side of one end of the mounting plate 201, and two symmetrical extrusion plates 203 are provided inside the connecting groove 206, and a support plate 204 is rotatably connected between the two extrusion plates 203, one end of one of the extrusion plates 203 is rotatably connected to the inner side of the connecting groove 206, and one end of the other extrusion plate 203 is rotatably connected to the driving plate 205. The rotating connection is conducive to the installation of multiple mounting plates 201 through the action of multiple mounting grooves 202. By driving and controlling the driving plate 205, the driving plate 205 drives one of the extrusion plates 203 to squeeze the support plate 204. With the cooperation of the other extrusion plate 203, the support plate 204 slides out and supports the wall, so that the door and window body 1 is stably engaged on the wall, and the supporting position of the support plate 204 is adjusted by controlling the sliding position of the driving plate 205. When convenient, the installation angle of the door and window body 1 is flat and stable, and the adjustment is easier and more convenient, thereby improving the overall installation efficiency.

[0031] Specifically, the driving mechanism 3 includes a movable groove 303. The driving plate 205 is provided with the movable groove 303. A rack 304 is installed inside the movable groove 303. The rack 304 is fixedly connected to the driving plate 205. A gear 302 is arranged inside the movable groove 303. The gear 302 meshes with the rack 304. A driving rod 301 is vertically and rotatably connected to the mounting plate 201. The driving rod 301 extends into the movable groove 303. The gear 302 is fixedly connected to the driving rod 301. The top of the driving rod 301 is of an internal hexagonal structure. Through the installation of the driving rod 301, it is beneficial to connect and control the gear 302. By driving and controlling the driving rod 301 with a wrench, the gear 302 drives the rack 304, and the rack 304 drives the driving plate 205 to slide and control inside the mounting plate 201, so as to realize the control and adjustment of the pressing plate 203, and the operation is more convenient and labor-saving.

[0032] Specifically, the protection mechanism 5 includes a helical gear disk 501. The helical gear disk 501 is installed on the driving rod 301. The helical gear disk 501 is rotatably connected to the inner side of the mounting plate 201 through the driving rod 301. A clamping block 502 is installed on the inner side of the mounting plate 201. The clamping block 502 is slidably connected to the inside of the mounting plate 201 through a contact spring 503. One end of the clamping block 502 abuts against the outer side of the helical gear disk 501. The pointed teeth at one end of the clamping block 502 are in the opposite direction to the pointed teeth of the helical gear disk 501. When driving and controlling the driving rod 301, the driving rod 301 drives the helical gear disk 501 to rotate. When the helical gear disk 501 rotates, it abuts against the clamping block 502, enabling the clamping block 502 to contract, facilitating the rotation of the helical gear disk 501. Since the pointed teeth at one end of the clamping block 502 are in the opposite direction to the pointed teeth of the helical gear disk 501, after the helical gear disk 501 rotates, the clamping block 502 abuts against the helical gear disk 501 and cannot rotate in the reverse direction, which is beneficial to the stable rotation of the gear 302 without loosening, making the support plate 204 support stably and firmly, and improving the stability of the door and window body 1.

[0033] Specifically, the extrusion mechanism 6 includes a return spring 603. The return spring 603 is installed inside the drive rod 301. The helical gear disk 501 is slidably connected to the drive rod 301 through the return spring 603. A pressure rod 601 is slidably connected to the drive rod 301. The pressure rod 601 extends into the drive rod 301 and is connected to the center of the helical gear disk 501. By installing the return spring 603, it is beneficial for the helical gear disk 501 to be slidably connected to the drive rod 301. Under the resistance of the return spring 603, the helical gear disk 501 is engaged with the block 502, enabling one-way rotation. By squeezing the pressure rod 601 with a wrench, the pressure rod 601 drives the helical gear disk 501 to slide down under the action of getting rid of the return spring 603, separating the helical gear disk 501 from the block 502, facilitating the free rotation of the drive rod 301 and realizing the reset work of the support plate 204.

[0034] Specifically, a guide rod 602 is installed at the center of the bottom of the helical gear disk 501. The guide rod 602 passes through the return spring 603 and is slidably connected to the inside of the drive rod 301. Under the action of the guide rod 602, the helical gear disk 501 slides smoothly and stably on the drive rod 301, and the helical gear disk 501 will not be skewed and unable to contact the block 502 to realize one-way rotation control.

[0035] Specifically, the fixing mechanism 4 includes a groove 403. Grooves 403 are provided on both sides of the mounting plate 201. Symmetrical pressure blocks 402 are installed inside the side wall of the door and window body 1. One side of the pressure block 402 extends into the mounting groove 202. One side of the pressure block 402 contacts the inside of the groove 403. A screw rod 401 is threadedly connected to the side wall of the door and window body 1. One end of the screw rod 401 is rotatably connected to the inside of the pressure block 402. After the mounting plate 201 is engaged with the inside of the mounting groove 202, by driving and controlling the screw rod 401 with a wrench, under the action of the thread, the screw rod 401 drives the pressure block 402, and the pressure block 402 contacts the inside of the groove 403 on the side wall of the mounting plate 201, making the mounting plate 201 firmly and stably connected inside the mounting groove 202. By rotating the screw rod 401 in the reverse direction, the pressure block 402 is separated from the groove 403, facilitating the disassembly and assembly of the mounting plate 201.

[0036] Specifically, the stabilizing mechanism 7 includes fixing grooves 701. A plurality of fixing grooves 701 are provided on the door and window body 1. A sliding sleeve 702 is arranged inside the fixing groove 701. The sliding sleeve 702 has an internal cylindrical "T" - shaped structure. The sliding sleeve 702 is slidably connected to the inside of the fixing groove 701 through a compression spring 703. The fixing groove 701 facilitates the insertion of bolts. The door and window body 1 and the wall are fixed by bolts. Through the installation of the sliding sleeve 702, under the action of the compression spring 703, the sliding sleeve 702 has local telescopic properties. After the bolt penetrates into the sliding sleeve 702, the bolt abuts against the sliding sleeve 702. Under the action of the compression spring 703, the sliding sleeve 702 always abuts tightly against the door and window body 1, making the installation of the door and window body 1 and the wall firm and stable.

[0037] When the present invention is in use, it is firstly convenient to install multiple mounting plates 201 through the action of multiple mounting grooves 202, and by driving and controlling the driving plate 205, the driving plate 205 drives one of the extrusion plates 203 to squeeze the support plate 204, and with the cooperation of the other extrusion plate 203, the support plate 204 slides out and supports the wall, so that the door and window body 1 is stably engaged on the wall, and by controlling the sliding position of the driving plate 205, the supporting position of the support plate 204 is adjusted, so that the installation angle of the door and window body 1 is flat and stable, and it is easier and more convenient to adjust, thereby improving the overall installation efficiency, and by installing the driving rod 301, it is convenient to control the connection of the gear 302, and by driving and controlling the driving rod 301 with a wrench, The gear 302 drives the rack 304, and the rack 304 drives the driving plate 205 to slide and control inside the mounting plate 201, so as to realize the control and adjustment of the extrusion plate 203, and the operation is more convenient and labor-saving. When the driving rod 301 is driven and controlled, the driving rod 301 drives the bevel gear plate 501 to rotate, and the bevel gear plate 501 resists the block 502 when rotating, so that the block 502 can shrink, which is convenient for the rotation of the bevel gear plate 501. Since the sharp teeth at one end of the block 502 are in opposite directions to the sharp teeth of the bevel gear plate 501, after the bevel gear plate 501 rotates, the block 502 resists the bevel gear plate 501 and cannot rotate in the opposite direction, which is conducive to the stability of the gear 302 after rotation. It will not loosen, so that the support plate 204 is supported stably and firmly, and the stability of the door and window body 1 is improved. The installation of the spring 603 is conducive to the sliding connection between the bevel gear plate 501 and the driving rod 301. Under the resistance of the reset spring 603, the bevel gear plate 501 is engaged with the block 502, and one-way rotation can be achieved. By squeezing the pressure rod 601 with a wrench, the pressure rod 601 drives the bevel gear plate 501 to get rid of the action of the reset spring 603 and slide down, so that the bevel gear plate 501 and the block 502 are separated, which is convenient for the driving rod 301 to rotate freely and realize the reset work of the support plate 204. Under the action of the guide rod 602, the bevel gear plate 501 slides smoothly and stably on the driving rod 301, and the bevel gear plate 501 will not be deflected and cannot conflict with the block 502 to realize one-way rotation control. After the mounting plate 201 is engaged with the inside of the mounting groove 202, the bevel gear plate 501 is engaged with the mounting groove 202 by a wrench. The driving control of the screw rod 401 causes the screw rod 401 to drive the pressing block 402 under the action of the thread, and the pressing block 402 contacts the inside of the groove 403 of the side wall of the mounting plate 201, so that the mounting plate 201 is firmly and stably connected inside the mounting groove 202. By rotating the screw rod 401 in the opposite direction, the pressing block 402 is separated from the groove 403, which is convenient for disassembly and assembly of the mounting plate 201. The fixing groove 701 facilitates the insertion of bolts, and the door and window body 1 is fixed to the wall by bolts. Through the installation of the sliding sleeve 702, the sliding sleeve 702 is locally retracted under the action of the compression spring 703. After the bolt penetrates into the interior of the sliding sleeve 702, the bolt contacts the sliding sleeve 702. Under the action of the compression spring 703, the sliding sleeve 702 always contacts tightly with the door and window body 1.Make the door and window body 1 firmly and stably installed on the wall.
