Description

Technical Field

[0001] The utility model relates to a tension adjusting member of a door lock, more specifically to a tension adjusting device applied to the door lock. Background Art

[0002] When installing a door lock, you need to install a door latch stopper. The door latch stopper is a door lock accessory used to cooperate with the door latch. Door locks produced by different manufacturers or door locks of different models will have door latch stops of different thicknesses and sizes. Therefore, when installing and using the door lock, due to the mismatch in thickness between the door latch stopper and the door latch, it is easy to leave a door gap after the door leaf is closed, and the door leaf cannot be closed tightly, the sound insulation effect is poor, and the door gap cannot be adjusted at will.

[0003] In order to overcome the above-mentioned shortcomings and deficiencies, the inventor has designed a tension adjuster for a door lock, which can not only flexibly select and adjust the thickness of the door tongue stopper according to actual use needs, so that the door tongue stopper can better buckle against the door tongue and maintain the tightness of the door leaf after closing, but also can effectively improve the sound insulation effect of the door leaf and improve the use function of the door leaf. Utility Model Content

[0004] The utility model discloses a slack adjuster applied to a door lock, the main purpose of which is to overcome the above-mentioned deficiencies and shortcomings of the prior art.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A tension adjuster used for door locks, including a tension piece body, a mounting portion protruding upward is provided in the middle of the tension piece body, a mounting hole is drilled in the middle of the mounting portion, an internal thread is provided in the mounting hole, a fixing bolt is passed through the mounting hole, and the tension piece body is locked and fixed by the fixing bolt; four sides of the tension piece body are respectively provided with four door tongue stoppers of different thicknesses.

[0007] Furthermore, the thicknesses of the four door latch stoppers increase or decrease sequentially along the same direction.

[0008] Furthermore, the front end of the door latch block is provided with an arc-shaped front end surface.

[0009] Furthermore, the elastic member body is an elastic member body made of metal material with an integrated structure.

[0010] Furthermore, the mounting portion is in a cylindrical or rectangular structure.

[0011] It can be seen from the above description and explanation of the utility model that, compared with the prior art, the advantages of the utility model are:

[0012] Advantage 1: The utility model provides a mounting portion, four door latch stoppers of different thicknesses and fixing bolts, and can flexibly select door latch stoppers of different thicknesses for installation and fixing, so that it can better match the door latch, make the door leaf tighter after closing, and improve the sound insulation effect of the door leaf.

[0013] Advantage 2: The utility model provides an arc-shaped front end surface on the door latch stopper, so that the door latch can slide in more smoothly when buckled, and the door can be closed more lightly and with a better feel. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a front view structural schematic diagram of the first embodiment of the utility model.

[0015] Figure 2 It is a schematic diagram of the back structure of the first embodiment of the utility model.

[0016] Figure 3 It is a structural schematic diagram of the first embodiment of the utility model.

[0017] Among them, the tensioner body 1, the mounting portion 2, the mounting hole 3, the internal thread 31, the fixing bolt 4, the door latch stopper 5, and the front end surface 51. DETAILED DESCRIPTION

[0018] The specific implementation of the present invention will be further described and illustrated below with reference to the accompanying drawings.

[0019] Embodiment 1:

[0020] like Figures 1 to 3 As shown, a tension adjuster used for door locks includes a tension member body 1, a mounting portion 2 protruding upward is provided in the middle of the tension member body 1, a mounting hole 3 is drilled in the middle of the mounting portion 2, an internal thread 31 is provided in the mounting hole 3, a fixing bolt 4 is provided through the mounting hole 3, and the tension member body 1 is locked and fixed by the fixing bolt 4. The tension member body 1 is a stainless steel tension member body with an integrated structure, and the mounting portion 2 is cylindrical.

[0021] like Figures 1 to 3As shown, four door oblique tongue stoppers 5 of different thicknesses are respectively arranged on the four sides of the tensioner body 1, and the door oblique tongue stoppers 5 are arranged to match the door oblique tongue and to be movable against it. The thickness of the four door oblique tongue stoppers 5 increases in sequence in the clockwise direction. The front end of the door oblique tongue stopper 5 is provided with an arc-shaped front end face 51. By providing the arc-shaped front end face 51 on the door oblique tongue stopper 5, the door oblique tongue can slide in more smoothly when buckling, and the door can be closed more lightly and with a better feel. By providing the mounting portion 2, four door oblique tongue stoppers 5 of different thicknesses and the fixing bolts 4, the door oblique tongue stoppers of different thicknesses can be flexibly selected for installation and fixing, so that they can better match the door oblique tongue, so that the door leaf can be more tightly closed, and the sound insulation effect of the door leaf can be improved.

[0022] When using:

[0023] Select a door latch stopper 5 of matching thickness, then fix the tensioner body 1 on the door frame, and pass the fixing bolts 4 through the mounting holes 3 on the mounting portion 2, and then lock and fix, thereby completing the fixing of the tensioner body 1.

[0024] When the tightness of the door leaf needs to be adjusted, the fixing bolt 4 can be loosened first, and then the door latch block 5 can be rotated to select a side of the door latch block 5 with a more suitable thickness, and then the fixing bolt 4 can be re-tightened to complete the tightness adjustment.

[0025] Embodiment 2:

[0026] The main difference between this embodiment and the first embodiment is that the mounting portion 2 of this embodiment is in a rectangular structure, which can further improve the strength and area of ​​the mounting portion 2. The other structures are the same as those of the first embodiment and will not be repeated here.

[0027] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial improvement of the utility model using this concept should be regarded as an infringement of the protection scope of the utility model.
