Description

Technical Field

[0001] The invention relates to the technical field of window structures, and in particular to a crank push rod connection structure, a horizontal push window handle and a disassembly and assembly method thereof. Background Art

[0002] Glass curtain walls are widely used because of their good light transmittance and sight line, and convenient and quick installation. Among them, curtain wall sliding windows are the most widely used. Curtain wall sliding windows usually use sliding window handles. The installation of sliding window handles is special. They include handle seats arranged on both sides of the sliding window. When the sliding window is pushed outward, a push rod needs to be arranged in the middle of the two handle seats. During installation, the distance between the left and right handle seats of the sliding window handle is fixed. In addition, the fork protruding from the bottom of the handle seat must be installed first, otherwise the entire handle cannot be put in and cannot be installed. Therefore, the handle seats on the left and right sides are installed first, and then the two ends of the push rod body are connected to the handle seats on the left and right sides. The installation of the push rod body is not very convenient.

[0003] In addition, the crank body of the traditional sliding window handle is often enlarged and made into a boss with a round hole. When installing the push rod body, it is necessary to first insert it into the round hole of the crank body on one side and then align it with the round hole of the crank body on the other side and insert it a certain distance. Then, screw the screw from the crank body and screw it into the fixing hole on the push rod body. The installation steps are relatively cumbersome. Fig. 9 and Fig.10 As shown in the figure, the traditional horizontal push window handle is not only slightly bulky and unsightly, but also more troublesome to install and has higher installation requirements. In addition, the requirements for the length of the push rod body and the position of the fixing hole on the push rod body are relatively high. Once a large processing error occurs, it will cause installation abnormality. Moreover, the connection between the push rod body and the crank body is only through a screw inserted into the fixing hole on the push rod body, and the connection strength is slightly insufficient. Summary of the invention

[0004] The object of the present invention is to provide a crank push rod connection structure, a sliding window handle and a disassembly and assembly method thereof, so as to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0005] The technical solutions adopted to solve the above technical problems are:

[0009] As a further improvement of the above technical solution, an elastic member is provided in the axial hole, and the elastic member is used to provide elastic force to make the clamping member located in the axial hole. Before installing the push rod body, the first clamping portion of the clamping member will not protrude from the end surface of the crank body, and will not affect the push rod body from being clamped into the two crank bodies, making installation more convenient.

[0010] As a further improvement of the above technical solution, the end of the clamping part away from the push rod body is provided with a sleeve, and an abutment boss is provided in the axial hole. The elastic part is a spring, and the springs are respectively on the sleeves. The springs abut the bosses of the sleeves and the abutment bosses respectively. On the one hand, it is convenient to install the spring. The sleeve and the elastic part clamping part can be arranged on the crank body and pre-installed during the production process, which is convenient for transportation and subsequent actual installation.

[0011] As a further improvement of the above technical solution, the end of the axial hole close to the push rod body is provided with a movable groove, the end of the axial hole away from the push rod body is provided with a mounting groove, the first clamping portion is movably arranged in the movable groove, and the sleeve is movably arranged in the mounting groove. After installation, the sleeve will not protrude from the end of the push rod body, which looks more beautiful.

[0012] As a further improvement of the above technical solution, the crank body is provided with a positioning groove, and the push rod body is provided with a decorative groove corresponding to the positioning groove, so as to facilitate the corresponding clamping of the first clamping part and the second clamping part.

[0013] As a further improvement of the above technical solution, the second clamping portion is eccentrically arranged with respect to the push rod body, which not only realizes the function of positioning the push rod body and preventing it from rotating at will, but also strengthens the connection strength between the push rod body and the crank body.

[0014] The present invention also provides a horizontal sliding window handle, comprising a handle seat, two handle handles, and a crank push rod connection structure as described in any one of the above, wherein the two handle seats are arranged at intervals, the two handle handles are respectively arranged on the two handle seats, one of the handle handles is the crank body, and the two ends of the push rod body are respectively connected to the crank body and the handle handle, making installation more convenient.

[0015] As a further improvement of the above technical solution, the two handles are both crank bodies, and both ends of the push rod body are connected by the crank push rod connection structure. The crank bodies at both ends of the push rod body have no order of installation, which makes installation more convenient.

[0016] The present invention also provides a method for disassembling and assembling a horizontal push window handle, wherein the horizontal push window handle described above is inserted into the axial hole by aligning the clamping member with the crank body and close to the push rod body;

[0017] Put the spring sleeve on the shaft sleeve, put the shaft sleeve on the axial hole on the other side, flatten it with a punching machine, and then press the clamping part and the shaft sleeve tightly;

[0018] Install the handle base and handles on the left and right sides;

[0019] The decorative groove on the push rod body is aligned with the positioning groove on the crank body, and then the connecting piece is passed through the shaft hole and threadedly connected to the end surface of the push rod body.

[0020] First, install the clamping member, the shaft sleeve, the first elastic member and the crank body. The first clamping portion of the clamping member will not protrude from the end surface of the crank body, and will not affect the insertion of the push rod body into the two crank bodies, making installation more convenient.

[0021] As a further improvement of the above technical solution, the assembly of the clamping member, the shaft sleeve, the first elastic member and the crank body is pre-installed during production. Pre-installation does not affect transportation and is more convenient for installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Reference Fig. 9 and Fig.10 The crank body 100 of a traditional sliding window handle is often enlarged and made into a boss with a round hole. When installing the push rod body 200, it needs to be inserted into the round hole of the crank body 100 on one side first, and then aligned with the round hole of the crank body 100 on the other side and inserted a distance, and then screwed in from the crank body 100 and screwed into the fixing hole on the push rod body 200. The installation steps are relatively cumbersome. Once a large processing error occurs, it will cause installation abnormalities. Moreover, the connection between the push rod body and the crank body is only through a screw inserted into the fixing hole on the push rod body 200, and the connection strength is slightly insufficient. Figures 1 to 8 The crank push rod connection structure, the horizontal push window handle and the disassembly method thereof of the present invention are implemented as follows:

[0040] In some embodiments, a crank push rod connection structure includes a crank body 100, a push rod body 200, and a connecting piece 300. Taking the crank push rod connection structure on the left side as an example, the connecting end of the crank body 100 is provided with a through-type axial hole, and the axial hole is extended left and right. The axial hole is sleeved with a clamping piece 400 with an axial hole 420. The clamping piece 400 is movably clamped in the axial hole and slides left and right in the axial hole. A first clamping portion is provided at one end of the clamping piece 400 close to the push rod body 200, and a second clamping portion engaged with the first clamping portion is provided at the end of the push rod body 200.

[0041] In the first clamping part and the second clamping part, one is a clamping protrusion 410, and the other is a clamping groove 210. Figure 2It can be seen that the clamping boss 410 is arranged on the clamping member 400, and the clamping groove 210 is arranged at the left end of the push rod body 200. It can be known that the clamping groove 210 can also be arranged on the clamping member 400, and the clamping boss 410 is arranged at the left end of the push rod body 200.

[0042] Furthermore, the number of the clamping bosses 410 is two, and the number of the clamping grooves 210 is also two accordingly, which can make the second clamping portion eccentrically arranged with the push rod body 200. This not only realizes the function of positioning the push rod body 200 so that it cannot rotate at will, but also strengthens the connection strength between the push rod body 200 and the crank body 100. It should be noted that the present invention does not specifically limit the number of the clamping bosses 410 and the clamping grooves 210.

[0043] Of course, in other embodiments, the locking boss 410 and the locking groove 210 can be set to an irregular shape to limit the rotation of the locking member 400 relative to the push rod body 200. For example, the cross-section of the locking boss 410 is triangular, and the corresponding cross-section of the locking groove 210 is triangular, which can limit the rotation of the push rod body 200 relative to the locking member 400.

[0044] The connecting member 300 passes through the shaft hole 420 and is threadedly connected to the end surface of the push rod body 200 to achieve threaded connection between the crank body 100 and the push rod body 200. The connecting member 300 is a fixing screw.

[0045] During installation, the two ends of the push rod body 200 can be snapped into the middle of the two handle seats 700, and then the connecting piece 300 passes through the axial hole 420 of the snap-in piece 400 and is threadedly connected to the end face of the push rod body 200 and drives the snap-in piece 400 to move toward the push rod body 200, so that the first snap-in part and the second snap-in part are snapped in engagement, that is, the snap-in boss 410 and the snap-in groove 210 are correspondingly snapped in engagement, which makes installation more convenient and the connection strength higher.

[0046] During installation, first install the two handle seats 700 on the window sash, the distance between the two handle seats 700 is fixed, and the left and right crank bodies 100 have been installed on the handle seats 700. At this time, connect the two ends of the push rod body 200 to the left and right crank bodies 100 respectively, and first extend the clamping boss 410 of the clamping piece 400 into the shaft hole 420 without affecting the clamping of the push rod body 200, thereby facilitating installation.

[0047] Furthermore, an elastic member 600 is provided in the axial hole, and the elastic member 600 is used to provide elastic force to make the clamping member 400 located in the axial hole. Before installing the push rod body 200, the first clamping portion of the clamping member 400 will not protrude from the end surface of the crank body 100, and will not affect the clamping of the push rod body 200 into the two crank bodies 100, which makes installation more convenient. If the elastic member 600 is not provided, the clamping boss 410 of the clamping member 400 needs to be manually extended into the shaft hole 420, and the installation is relatively complicated.

[0048] More specifically, the end of the clamping member 400 away from the push rod body 200 is sleeved with a shaft sleeve 500, an abutting boss 130 is arranged in the axial hole, and the elastic member 600 is a spring, which is respectively on the shaft sleeve 500 and abuts against the boss of the shaft sleeve 500 and the abutting boss 130. It is convenient to movably install the clamping member 400 in the axial hole for easy transportation.

[0049] During installation, the spring is sleeved on the sleeve 500, and the sleeve 500 is sleeved on the clamping member 400 from the axial hole on the other side, and the clamping member 400 and the sleeve 500 are pressed tightly after being flattened by a punching machine, which can also facilitate the installation of the spring. The sleeve 500, the elastic member 600 and the clamping member 400 can be preset on the crank body 100 and pre-installed during the production process, which is convenient for transportation and installation in subsequent practical applications.

[0050] In addition, during installation, the spring drives the sleeve 500 to move to the left, so that the end face of the left end of the push rod body 200 abuts against the right end face of the crank body 100 on the left side, which can play a locking role and also make the connection gap between the left end of the push rod body 200 and the crank body 100 on the left side smaller, which is more beautiful.

[0051] The end of the axial hole close to the push rod body 200 is provided with a movable groove 110, and the end of the axial hole away from the push rod body 200 is provided with a mounting groove 120. The first clamping part is movably arranged in the movable groove 110, and the sleeve 500 is movably arranged in the mounting groove 120. During pre-installation, the clamping boss 410 abuts against the boss 130 under the action of the spring, and will not extend out of the right end face of the crank body 100, which is convenient for installing the push rod body 200; after installation, the connecting member 300 passes through the axial hole 420 of the clamping member 400 and is threadedly connected with the end face of the push rod body 200 and drives the clamping member 400 to move toward the push rod body 200, and the sleeve 500 will not protrude from the left end of the crank body 100 and is located in the mounting groove 120, which is more beautiful. The sleeve 500 is provided with a space reserved for the connecting member 300, that is, the nut of the fixing nut, so that the nut will not protrude from the left end face of the crank body 100, which is more beautiful. The shaft sleeve 500 abuts against the abutting boss 130 to play a limiting role.

[0052] During actual installation, the engaging boss 410 and the engaging groove 210 need to correspond one to one in order to engage. However, during installation, the engaging boss 410 and the engaging groove 210 cannot be seen, so the engaging boss 410 needs to be rotated a certain angle to correspond. In order to solve this problem, the crank body 100 is provided with a positioning groove, and the push rod body 200 is provided with a decorative groove 220 corresponding to the positioning groove. During installation, when the decorative groove 220 corresponds to the positioning groove, the engaging boss 410 and the engaging groove 210 are also correspondingly arranged. At this time, the fixing screws can be directly tightened without considering whether the invisible engaging boss 410 and the engaging groove 210 correspond, which makes installation more convenient.

[0053] Furthermore, the engaging groove 210 can be used as a reinforcing rib, thereby greatly improving the strength of the push rod body 200 and meeting the requirement of a larger overall width of the sliding window.

[0054] Reference Figure 1 , Figure 5 , Figure 6 The present invention also provides an embodiment of a horizontal push window handle, which includes a handle seat 700, two handle handles, and a crank push rod connection structure of any one of the above items. The two handle seats 700 are arranged at intervals, and the two handle handles are respectively arranged on the two handle seats 700, one of the handle handles is a crank body 100, that is, the crank body 100 refers to one of the handle handles, and one end of the push rod body 200 can adopt the connection method of the present invention, and the other end can adopt the connection method of the present invention. Figure 6 The installation method of the left-hand handle is shown in .

[0055] by Figure 6 For example, when the left end of the push rod body 200 is directly connected to the left end structure of the push rod body 200 after passing through the crank body 100 with a fixing nut, and the right end thereof adopts the connection method of the present invention, it is necessary to first fix the left end of the push rod body 200, and then fix the right end of the push rod body 200, which will cause the problem of the order of installation. If the worker fails to see clearly during installation and first installs and fixes the right end of the push rod body 200, the installation of the left end of the push rod body 200 will be affected, and the installation is not convenient enough, which affects the installation efficiency, but it requires fewer parts and the positioning is more accurate.

[0056] by Figure 5 For example, the two handles are crank bodies 100, and both ends of the push rod body 200 are connected by a crank push rod connection structure. The crank bodies 100 at both ends of the push rod body 200 have no order of installation, which makes installation more convenient, reduces installation requirements, and has higher installation efficiency.

[0057] The present invention also provides a method for disassembling and assembling a horizontal push window handle. For the horizontal push window handle described above, the clamping member 400 is aligned with the crank body 100 and is close to the push rod body 200 and is inserted from the axial hole;

[0058] The spring is sleeved on the shaft sleeve 500, and the shaft sleeve 500 is sleeved on the clamping member 400 from the axial hole on the other side, and the clamping member 400 and the shaft sleeve 500 are pressed tightly after being flattened by a punching machine. The clamping member 400 and the shaft sleeve 500 form an interference fit, and the connection between the clamping member 400 and the shaft sleeve 500 is more secure, and finally the clamping member 400, the shaft sleeve 500, the first elastic member 600 and the crank body 100 are assembled. It is convenient to install the push rod body 200 later;

[0059] Install the handle bases 700 on the left and right sides, and then install the handles, that is, install the handle bases 700 on the left and right sides on the window sash, and then install the handles on the handle bases 700 on the left and right sides;

[0060] Specifically, the handle seat spring 710 and the steel ball 720 are installed into the two side slots on the rubber seat frame 730, and then the rubber seat frame 730 is placed into the groove of the handle seat 700, and then the gear shaft 740 is placed into the shaft hole in the middle of the rubber seat frame 730, and the handle seat sleeve 750 is placed on the other side of the handle seat 700, and then the left crank body 100 is aligned with the square hole of the gear shaft 740 and placed, and then fixed with the cross recessed countersunk screw 760. Referring to the above steps, the right crank body 100 and the handle seat 700 can be assembled.

[0061] Align the rack on the fork 770 with the gear on the gear shaft 740 and insert it, then assemble the bottom cover 780. At this time, rotating the crank body 100 can drive the fork 770 to move along the guide groove on the handle seat;

[0062] Align the rack on the shift fork 770 with the gear on the gear shaft 740 and insert it, then assemble the bottom cover 780 . At this time, rotating the crank body 100 can drive the shift fork 770 to move along the guide groove on the handle seat 700 .

[0063] The decorative groove 220 on the push rod body 200 is aligned with the positioning groove on the crank body 100 , and then the connecting piece 300 is passed through the shaft hole 420 and threadedly connected to the end surface of the push rod body 200 .

[0064] First, install the clamping member 400, the sleeve 500, the first elastic member 600 and the crank body 100. The first clamping portion of the clamping member 400 will not protrude from the end surface of the crank body 100, and will not affect the insertion of the push rod body 200 into the two crank bodies 100, making the installation more convenient. It should be noted that the installation structure of the handle seat 700 is a prior art and is not specifically limited in the present invention. In addition, the method steps described in this embodiment are the order of installation in sequence unless otherwise specified.

[0065] In actual production, the push rod body 200 does not need to be assembled with the two crank bodies 100, because it is not convenient to pack and transport them together, and because the two crank bodies 100 need to be installed before the push rod body 200 when installing the handle. Furthermore, the assembly of the clamping member 400, the sleeve 500, the first elastic member 600 and the crank body 100 is pre-installed during production. Pre-installation does not affect transportation and packaging, and installation is more convenient.

[0066] The overall structure of the clamping part 400, the sleeve 500, the first elastic part 600 and the crank body 100 of the present invention is provided with the first elastic part 600, that is, a spring. Under the action of the spring, the clamping boss 410 moves to the left and abuts against the side surface of the boss 130, and will not extend out of the right end surface of the crank body 100. It also serves to facilitate the relative fixation of the clamping part 400 and the sleeve 500 in the axial hole in the crank body 100. No large shaking will occur during transportation, which is convenient for transportation and does not affect packaging.

[0067] The preferred embodiments of the present invention are specifically described above, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
