Description

Technical Field

[0001] The utility model relates to the field of door and window locks, in particular to a strip lock handle structure. Background Art

[0002] The strip lock of the sliding door lock realizes the locking or unlocking of the sliding door by driving the fork up and down by the handle. In order to make the handle move more smoothly, the Chinese patent document discloses a technical solution with an application number of "202120090732.X" and the name of "A door and window strip lock". The technical solution is achieved by arranging a sliding member with a plurality of steel balls on both sides on the fixed seat. The sliding seat slides along the steel balls when moving, so that the sliding seat can slide smoothly on the fixed seat.

[0003] However, there are still some problems and shortcomings in the production and use of this technology, as shown below:

[0004] First, the steel balls are arranged on both sides of the fixing seat, which will increase the width of the fixing seat, thereby making the size of the door and window strip lock relatively large. Therefore, it is not suitable for installation on narrow door frames, especially for sliding doors and windows with ultra-narrow frames that have been popular in recent years, which limits the scope of application of the door and window strip lock.

[0005] Second, there are steel balls on both sides of the fixing seat, which requires more steel balls, increases the difficulty of assembly and reduces efficiency. Workers spend more time installing the steel balls on the sliding parts, which makes the material cost and labor cost of the door and window strip lock relatively high and the market competitiveness is poor.

[0006] Therefore, in order to adapt to the current development and application of sliding doors and windows and to enhance the market competitiveness of products, it is very necessary to improve and upgrade the existing strip locks. Utility Model Content

[0007] The purpose of the utility model is to solve the above-mentioned problems and shortcomings and to provide a strip lock handle structure. The strip lock handle structure is provided with a steel ball assembly with a central steel ball structure between the fixed seat and the handle piece, which greatly simplifies the structure of the entire steel ball assembly on the one hand, reduces the material consumption, reduces the number of parts, reduces the production cost, and improves the assembly efficiency and product market competitiveness. On the other hand, the structural design of the steel ball assembly with the central steel ball structure greatly reduces the lateral width of the steel ball assembly, so that the lateral width of the strip lock handle can be made smaller, so that it can be widely used in sliding doors and windows with various frame widths, greatly expanding its scope of application.

[0008] The technical solution of the utility model is implemented as follows: a strip lock handle structure, including a fixing seat and a handle piece fitted with the fixing seat, and its characteristics are: the fixing seat is provided with a sliding groove in the middle along its length direction, and a steel ball assembly is arranged in the sliding groove; the steel ball assembly is composed of a retaining frame with a plurality of retaining holes in the middle and a first steel ball arranged in each retaining hole, and the inner side of the handle piece is arranged in contact with the first steel ball.

[0009] Furthermore, the retaining frame is provided with a protruding portion in the middle portion along the length direction thereof, and each retaining hole is formed on the protruding portion.

[0010] Furthermore, wedge-shaped insert plates are respectively provided on both sides of the retaining frame, a wedge-shaped slot engaged with the wedge-shaped insert plate is provided in the sliding groove, and an arc-shaped cavity groove for accommodating and sliding the first steel ball is also provided at the bottom of the wedge-shaped slot.

[0011] Furthermore, the handle piece is provided with a through groove for the fixing seat to be nested and installed, and a contact groove for the first steel ball to contact and slide is also provided on the groove bottom of the through groove.

[0012] Furthermore, plugs are respectively provided at both ends of the through slot of the handle piece to seal the fixed seat, a buckling portion is also provided on the plug, and buckling recesses that cooperate with the buckling portion are correspondingly provided on the groove edge of the through slot.

[0013] Furthermore, it also includes a fork mechanism, which includes a fork with a connecting hole, a baffle with a first through hole, and a screw. The fixing seat is also provided with a travel hole; the connecting hole is inserted into the travel hole from the back side of the fixing seat, and the baffle is placed on the fixing seat from the front cover of the fixing seat, and the fork is assembled with the fixing seat by passing the screw through the first through hole and screwing it into the connecting hole.

[0014] Furthermore, the fork mechanism also includes a connecting pin assembly, which is composed of a pin barrel and a first spring inserted on the pin barrel. The fork is also provided with a first pin hole, the baffle is also provided with a second through hole, and the handle piece is provided with a second pin hole; the first spring and the pin barrel are inserted in the first pin hole, and the other end of the pin barrel passes through the second through hole and is inserted in the second pin hole.

[0015] Furthermore, the pin barrel is also provided with a convex ring portion which is installed to limit the position with the second through hole.

[0016] Furthermore, a damping mechanism is provided between the fork and the fixing seat, and the damping mechanism is composed of a second spring, a second steel ball provided on one end of the second spring, and a damping hole.

[0017] Furthermore, a third pin hole is provided on the fork, the damping hole is arranged on the fixing seat, the second spring is inserted into the third pin hole, and the second steel ball is clamped on the damping hole.

[0018] The beneficial effects of the utility model are as follows: the utility model provides a steel ball assembly with a central steel ball structure in the sliding groove of the fixed seat, and does not need to provide steel balls on both sides of the steel ball assembly, which greatly simplifies the structure of the steel ball assembly and also greatly reduces the number of steel balls. On the one hand, it can reduce the raw material cost of the product, and on the other hand, it can also reduce the labor cost when assembling the fixed seat, thereby helping to reduce the production cost of the product and further helping to improve its market competitiveness. Secondly, through the steel ball assembly with a central steel ball structure, the internal space in the middle position of the sliding groove of the fixed seat is cleverly utilized for the steel ball assembly to slide along the middle of the sliding groove, avoiding the traditional solution of arranging the steel balls on both sides of the fixed seat and occupying the space on both sides of the fixed seat, thereby greatly reducing the size of the width direction of the transverse section of the fixed seat during design and production, thereby making the transverse section width of the entire handle product narrower, so that the product of the utility model can be used not only on wider door frames, but also on narrower door frames, and has a wider range of applications.

[0027] Fig. 9 The overall structure of the utility model is shown in FIG. Figure 2 . Implementation

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0029] like Figure 2 As shown, the utility model provides a strip lock handle structure, including a fixing seat 1 and a handle piece 2 fitted with the fixing seat 1. In order to achieve the purpose proposed by the utility model, the fixing seat 1 is provided with a sliding groove 11 in the middle of its length direction, and a steel ball assembly 4 is arranged in the sliding groove 11; the steel ball assembly 4 is composed of a retaining frame 41 with a plurality of retaining holes 43 in the middle and a first steel ball 42 arranged in each retaining hole 43, and the inner side of the handle piece 2 is arranged in contact with the first steel ball 42. In this way, not only can the structure of the fixing seat 1 be simplified and the amount of steel balls used be reduced, but also the size of the handle structure can be narrower, which is suitable for sliding door frames of various widths and has a wider range of applications. In addition, due to the simplified structure and the small amount of steel balls used, its material cost and assembly cost can also be effectively reduced, thereby increasing its market competitiveness.

[0030] like Figure 4 As shown, the retaining frame 41 is further provided with a protrusion 44 in the middle portion along its length direction, and each retaining hole 43 is opened on the protrusion 44, so that a larger contact surface is formed between the first steel ball 42 and the retaining hole 43, so that the first steel ball 42 is not easy to fall out of the retaining hole 43, and the first steel ball 42 can slide more smoothly in the retaining hole 43.

[0031] like Figure 4 , Figure 6 As shown, wedge-shaped insert plates 46 are respectively provided on both sides of the retaining frame 41, a wedge-shaped slot 12 is provided in the sliding groove 11 to be fitted with the wedge-shaped insert plates 46, and an arc-shaped cavity 13 is provided at the bottom of the wedge-shaped slot 12 for the first steel ball 42 to accommodate and slide. In this way, the retaining frame 41 can be fixed in the sliding groove 11 very conveniently, and the inner wall of the arc-shaped cavity 13 forms an arc-shaped contact surface with the first steel ball 42, so that the first steel ball 42 can slide more smoothly and prevent the first steel ball 42 from being stuck when sliding.

[0032] like Figure 5 , Figure 6As shown, the handle piece 2 is provided with a through groove 23 for nesting and installing the fixing seat 1, and a contact groove 21 for contacting and sliding the first steel ball 42 is also provided on the bottom of the through groove 23. In this way, the handle piece 2 can be used as a sliding seat, sliding along the length direction of the fixing seat, and can also be used as a handle, thereby simplifying the structure of the utility model, reducing the number of parts, and thus helping to reduce production costs; when the contact groove 21 contacts and slides with the first steel ball 42, the groove top edges on both sides of the contact groove 21 form a clamping effect on the first steel ball 42, so that the handle piece 2 is not easy to shake when sliding along multiple first steel balls 42, and is more stable when used, increasing the comfort of the user.

[0033] like Figure 1 , Figure 5 , Fig. 9 As shown, plugs 5 are provided at both ends of the through slot 23 of the handle member 2 to seal the fixed seat 1, and a buckle portion 51 is provided on the plug 5. A buckle recess 231 that is matched with the buckle portion 51 is provided on the groove edge of the through slot 23. In this way, when the product leaves the factory or is used, the product appearance can be made neat, and the internal parts are not easy to scatter or fall out; through the cooperation of the buckle portion 51 and the buckle recess 231, the plug 5 can be easily installed or removed from the handle member 2, so as to facilitate the installation of the handle structure on the door and window.

[0034] like Figure 1 , Figure 2 , Figure 3 , Fig. 9 As shown, it also includes a fork mechanism 3, which includes a fork 31 with a connecting hole 311, a baffle 32 with a first through hole 321, and a screw 33. The fixing seat 1 is also provided with a travel hole 15; the connecting hole 311 is inserted into the travel hole 15 from the back of the fixing seat 1, and the baffle 32 is placed on the fixing seat 1 from the front, and the screw 33 passes through the first through hole 321 and is screwed into the connecting hole 311 to assemble the fork 31 with the fixing seat 1. In this way, the fork 31 can slide up and down along the travel hole 15.

[0035] like Figure 2 , Figure 7As shown, the fork mechanism 3 also includes a connecting pin assembly 34, which is composed of a pin barrel 342 and a first spring 341 inserted in the pin barrel 342. The fork 31 is also provided with a first pin hole 312, the baffle 32 is also provided with a second through hole 322, and the handle member 2 is provided with a second pin hole 22; the first spring 341 and the pin barrel 342 are inserted in the first pin hole 312, and the other end of the pin barrel 342 passes through the second through hole 322 and is inserted in the second pin hole 22. When the handle 2 slides along the length direction of the fixed seat 1, the first spring 341 is compressed by the bottom of the through groove 23 on the handle 2, so that the handle 2 can continue to slide. When the pin barrel 342 is aligned with the second pin hole 22, the pin barrel 342 is pushed into the second pin hole 22 under the action of the first spring 341, so that the fork 31 and the handle 2 are connected. The handle 2 can drive the fork 31 to slide up and down. On the other hand, the pin barrel 342 is elastically pressed by the first spring 341 and can be inserted into the second pin hole 22 more stably, so that the pin barrel 342 is not easy to shake. Figure 5 As shown, a through hole is further provided at the bottom of the second pin hole 22, through which a pin can be used to push the pin barrel 342 to separate the handle 2 from the fork 31, so as to facilitate later replacement or maintenance.

[0036] like Figure 7 As shown, the pin barrel 342 is also provided with a convex ring portion 343 which is installed to form a limiting position with the second through hole 322. This can prevent the pin barrel 342 from falling out of the second through hole 322.

[0037] like Figure 2 As shown, a damping mechanism 35 is further provided between the fork 31 and the fixing seat 1, and the damping mechanism 35 is composed of a second spring 351, a second steel ball 352 provided on one end of the second spring 351, and a damping hole 353. In this way, when the handle 2 drives the fork 31 to slide up and down, the stroke position of the fork 31 can be sensed by the compression and rebound of the second spring 351, and a "click" sound can be heard when the second steel ball 352 slides into the damping hole 353, which helps to remind the user that the fork 31 has slid into place, thereby improving the user's comfort and convenience.

[0038] like Figure 2As shown, the fork 31 is also provided with a third pin hole 313, the damping hole 353 is arranged on the fixing seat 1, the second spring 351 is inserted into the third pin hole 313, and the second steel ball 352 is clamped on the damping hole 353. This will not increase the complexity of the structure of the fixing seat 1, and it is convenient to install the fixing seat 1 on the door frame; preferably, a third pin hole 313 is provided at each end of the fork 31, and two damping holes 353 are provided at each end of the travel hole 15 along the sliding direction of the fork 31, and the distance between the two damping holes 353 is equal to the travel distance of the fork 31. In this way, no matter where the fork 31 is, the second steel ball 352 can be clamped in the damping hole 353, so that the fork 31 and the fixing seat 1 are tightly fitted without leaving a gap.

[0039] like Figure 2 , Figure 3 As shown, a blocking block 6 is also provided on the fixing seat 1 between the steel ball assembly 4 and the travel hole 15 to prevent the steel ball assembly 4 from sliding into the damping hole 353 under the drive of the handle 2, so that the steel ball assembly 4 can only slide at a specific position. Figure 2 , Figure 8 As shown, the baffle block 6 is provided with a boss 61, and the baffle block 6 is buckled on the fixing seat 1 by inserting the boss 61 into the damping hole 353, and the side surface of the baffle block 6 located on the boss 61 is also made into a shape structure matching the groove bottom shape of the sliding groove 11, so that the baffle block 6 is more closely buckled in the sliding groove 11 of the fixing seat 1.
