Description

Technical Field

[0001] This utility model relates to the field of screen window lock technology, and more specifically to a novel lock that can be used on both left and right sides of a screen window. Background Technology

[0002] In the field of building doors and windows, screen locks are the core components for opening, closing, and locking screens. Their structural design and installation methods directly affect the user experience and project efficiency. Traditional screen locks generally adopt a left-right split design, meaning that left-opening and right-opening screens require different lock specifications. This design leads to the following technical problems:

[0003] Complex and costly inventory management: Manufacturers need to produce two types of locks, left and right, and distributors need to keep two sets of inventory, which increases mold development costs, warehouse space occupation and the risk of unsold goods.

[0004] Low installation efficiency: Installers need to determine the opening direction of the screen window in advance, distinguish between left and right locks, and then measure left and right. The work is complicated, and traditional locks often require complicated adjustments, making the installation of a single set time-consuming.

[0005] Therefore, how to provide a new type of lock that can be used for both left and right screen windows without distinguishing between left and right and is compatible with the screen window switch upon installation is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the present invention provides a novel lock that can be used for both left and right opening and closing of a screen window.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A novel lock for screen window operation that is usable on both sides includes: a lock housing, with symmetrical mounting holes at both ends of the top of the lock housing for fixed installation, and limiting holes spaced apart along the length of the front of the lock housing; a transmission bar slidably embedded in the lock housing, with a lock cylinder hole at the top of the transmission bar and limiting mechanism mounting holes at both ends of the transmission bar; a shift fork fixedly connected to the transmission bar through a shift fork fixing hole; a lock cylinder penetrating the lock cylinder hole of the transmission bar and fixedly connected to the shift fork; and a limiting mechanism installed in the limiting mechanism mounting hole of the transmission bar for positioning the transmission bar.

[0009] Preferably, two sets of limiting holes are symmetrically distributed at both ends of the inner sliding groove sidewall of the lock case. Specifically, the two sets of limiting holes are evenly spaced.

[0010] Preferably, the limiting mechanism mounting holes at both ends of the transmission bar correspond to the limiting holes on the lock housing, and the limiting mechanism mounting holes of the transmission bar are through holes.

[0011] Preferably, the transmission bar has symmetrical structures at both ends, allowing it to be inserted into the lock housing in either direction.

[0012] Preferably, the lock cylinder hole is a polygonal hole that matches the end shape of the lock cylinder, ensuring that the transmission bar slides synchronously when the lock cylinder rotates.

[0013] Preferably, the limiting mechanism includes a limiting ball and a limiting spring, and the limiting mechanism is installed in the limiting mechanism mounting hole of the transmission bar.

[0014] As can be seen from the above technical solution, compared with the prior art, the novel lock for screen window opening and closing disclosed in this utility model allows users to quickly install left and right screen windows by using a set of locks and flipping them over, reducing inventory costs and improving installation efficiency (workers do not need to distinguish between left and right locks, they can use them directly).

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model discloses a novel lock for screen window operation that is usable on both sides, comprising: a lock housing 1, wherein the top of the lock housing 1 is symmetrically provided with mounting holes 101 for fixed installation at both ends, and limiting holes 102 are provided at intervals along the length direction on the front of the lock housing 1; a transmission bar 2, which is slidably embedded in the lock housing 1, wherein the top of the transmission bar 2 is provided with a lock cylinder hole 202, and both ends of the transmission bar 2 are respectively provided with limiting mechanism mounting holes 201; a shift fork 3, which is fixedly connected to the transmission bar 2 through a shift fork fixing hole 301; a lock cylinder 4, which passes through the lock cylinder hole 202 of the transmission bar 2 and is fixedly connected to the shift fork 3; and a limiting mechanism 5, which is installed in the limiting mechanism mounting hole 201 of the transmission bar 2 for positioning the transmission bar 2.

[0021] The lock housing 1 is elongated and has mounting holes 101 symmetrically provided at both ends of the top. A rectangular opening is provided at the center of the lock housing 1 to accommodate the transmission bar 2. Two sets of limiting holes 102 are symmetrically distributed at both ends of the inner sliding groove sidewall of the lock housing 1. Specifically, the two sets of symmetrically distributed limiting holes 102 each have three limiting holes evenly spaced.

[0022] The transmission bar 2 is slidably embedded in the inner groove of the lock housing 1. The limiting mechanism mounting holes 201 at both ends of the transmission bar 2 correspond to the limiting holes 102 on the lock housing 1. The limiting mechanism mounting holes 201 of the transmission bar 2 are through holes, allowing the limiting mechanism 5 to be installed bidirectionally within these holes, ensuring that the limiting ball 501 always springs towards the limiting hole 102 of the lock housing 1. Furthermore, the transmission bar 2 has symmetrical structures at both ends, allowing it to be inserted into the lock housing 1 in both directions, accommodating the left and right side screens. Simultaneously, the lock cylinder hole 202 is a polygonal hole, matching the end shape of the lock cylinder 4, ensuring that the transmission bar 2 slides synchronously when the lock cylinder 4 rotates.

[0023] The shift fork 3 is fixedly connected to the fixing hole 302 at the bottom of the transmission bar 2 through the shift fork fixing hole 301. The lock cylinder 4 and the lock cylinder hole 202 of the transmission bar 2 are in clearance fit. When the lock cylinder 4 is rotated, the transmission bar 2 moves in a straight reciprocating motion along the lock shell 1.

[0024] The limiting mechanism 5 includes a limiting ball 501 and a limiting spring 502. The limiting mechanism 5 is installed in the limiting mechanism mounting hole 201 of the transmission bar. The limiting spring 502 provides elastic force to make the limiting ball 501 engage with the limiting hole 102 of the lock housing 1. The limiting mechanism 5 can selectively engage with the limiting holes 102 on the left or right side of the lock housing 1, so that the transmission bar 2 can achieve bidirectional limiting function when switching between left and right pushing and pulling directions. The limiting ball 501 of the limiting mechanism 5 is a metal ball or a nylon ball with a smooth surface to reduce friction with the limiting hole 102 of the lock housing and improve service life.

[0025] Screen installation and use: Install the lock, fixing the lock housing 1 into the lock groove of the screen frame through the mounting hole 101, ensuring that the lock housing is parallel to the direction of movement of the screen. Insert the transmission bar 2 into the lock housing slide groove in the forward direction, and the limiting ball 501 of the limiting mechanism 5 naturally engages with the limiting hole 102 of the lock housing 1. Then insert the lock cylinder 4 into the lock cylinder hole 202 of the transmission bar 2, and then fix the screen handle to the exposed end of the lock cylinder 4, ensuring that the rotation direction of the handle matches the movement of the transmission bar (e.g., when the handle is turned downwards, the transmission bar slides downwards, and when the handle is turned upwards, the transmission bar slides upwards).

[0026] Turning the screen handle upwards or downwards will slide the drive bar 2 downwards or upwards (the limit ball 501 compresses the spring and disengages from the current limit hole, then re-engages when sliding to the lower or upper limit hole, thus achieving positioning). This is used to lock the screen. To unlock, turning the screen handle to center it (with the handle perpendicular to the screen) engages the limit ball 501 of the limit mechanism 5 with the lock housing limit hole in the middle of the lock housing 1, thus unlocking the screen.

[0027] This utility model discloses a novel lock that can be used for both left and right screen windows. When installing left and right screen windows, users can quickly install both screen windows by simply flipping the lock on one set, reducing inventory costs and improving installation efficiency (workers do not need to distinguish between left and right locks, they can be used interchangeably).

[0028] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
