The spring seat adopts a disc structure with a cylindrical connecting clamp column in the middle, and the cylindrical connecting clamp column is used to extend into the center hole of the lining body, and the top of the cylindrical connecting clamp column is provided with a barb for realizing the connection between the spring seat and the lining body. A C-shaped spring limiting step is provided at the outer diameter of the spring seat, and when the spring clamping seat is clamped into the circular clamping groove of the spring seat, the C-shaped spring limiting step is located on the outside of the C-shaped spring anti-swing step, and the top ends of both sides of the C-shaped spring limiting step are respectively close to the top ends of both sides of the C-shaped spring anti-swing step, and the spring adopts a circular elastic member with two symmetrical external hanging angles, and the circular elastic member is sleeved on the outside of the cylindrical connecting clamping column, and the two external hanging angles are respectively tightened on the top ends of both sides of the C-shaped spring limiting step and the C-shaped spring anti-swing step;

[0006] The inner side of the cylindrical wall of the cylindrical connecting column is provided with two symmetrically arranged latching protrusions, which are used to engage with the handle insertion end. Then, the latching protrusions drive the spring clamping seat to rotate under the external force of the handle insertion end, and the spring clamping seat causes the spring tension to increase. When the external force disappears, the handle insertion end returns to its initial state under the action of the spring rebound force.

[0007] As a further improvement, a spring limiting protrusion is also provided in the circular groove of the spring seat, and the spring limiting protrusion is arranged in the middle position of the C-shaped opening side of the C-shaped spring stop step.

[0015] The present invention also provides a split door lock, comprising the above-mentioned split door lock handle lining.

[0016] After adopting such a design, the present invention has at least the following advantages:

[0017] 1. The split door lock handle lining of the present invention is provided with a spring and a spring seat on the lining body, and a clamping protrusion is provided on the spring seat, so that the handle is engaged and connected with the spring seat, and then the C-shaped spring limiting step on the spring seat and the C-shaped spring anti-swing step on the lining body cooperate to achieve that when the spring seat rotates, the spring tension is continuously increased, and the spring seat returns to its initial state under the action of the spring rebound force after the external force disappears, so as to ensure that the handle is always in a horizontal state in a natural state, and effectively prevent the problem of the existing handle sagging after being used for a period of time.

[0018] 2. The convex part on the spring clamping seat is arranged into a trapezoidal clamping platform structure, and an elastic opening is arranged on the trapezoidal clamping platform structure. The elastic opening can make the connection with the insertion end of the handle tighter, which is not easy to fall out, and further eliminates the gap between the handle and the lining, thus completely solving the problem of invalid up and down swinging of the handle.

[0019] 3. By setting the position of the spring limit protrusion, the handle can be freely rotated left and right. After turning to a certain angle, the spring is blocked by the position of the limit protrusion and stops the handle from rotating. During installation, the lining panel is not divided into left and right, which improves the flexibility of installation.

[0020] 4. The arrangement of the cylindrical connecting clamping column on the spring clamping seat, as well as the arrangement of the arc-shaped inverted hanging column and the conical hook at the end of the clamping column, can conveniently and quickly assemble the spring clamping seat, the spring and the liner body, thereby increasing work efficiency and reducing labor costs.

[0021] 5. By setting the spring external hanging angle to be inclined toward the radial center plane of the spring, the thickness of the spring can be reduced, which facilitates the rotation of the spring with the spring holder in the circular groove, making the handle rotate more smoothly and lightly, and having strong practicality.

[0030] Refer to the attached Figures 1 to 6 As shown, the split door lock handle lining of this embodiment includes a lining body 1, a spring seat 2 and a spring 3.

[0031] The inner side of the lining body 1 is provided with a spring seat circular clamping groove 12 arranged along the lining body center hole 11, which is used to clamp the spring 3 and the spring clamping seat 2. The circular clamping groove 12 is provided with a C-shaped spring anti-sway step 13.

[0032] The spring holder 2 is a disc structure with a cylindrical connecting column 21 in the middle. The cylindrical connecting column 21 is used to extend into the central hole 11 of the liner body, and the top of the cylindrical connecting column 21 is provided with a barb for connecting the spring holder 2 to the liner body 1. Figure 2 In this embodiment, the top of the cylindrical connection clamp column 21 is provided with a plurality of arc-shaped inverted hanging columns 211 evenly arranged in a circle, and the outer side of each inverted hanging column 211 is provided with a conical barb 212, and a push rod 213 is provided between two adjacent arc-shaped inverted hanging columns 211. The inner side of the central hole 11 of the liner body is provided with an inward guide platform 15, so that the cylindrical connection clamp column 21 can be easily inserted into the central hole 11.

[0033] A C-shaped spring limiting step 22 is provided at the outer diameter of the disc structure of the spring clamp 2. When the spring clamp 2 is inserted into the circular clamping groove 12 of the spring seat, the C-shaped spring limiting step 22 is located on the outside of the C-shaped spring stop step 13, and the top ends of both sides of the C-shaped spring limiting step 22 are respectively close to the top ends of both sides of the C-shaped spring stop step 13.

[0034] In this embodiment, the spring 3 is a circular elastic member with two symmetrical external hanging angles 31, which is sleeved on the outside of the cylindrical connecting clamp column 21, and the two external hanging angles 31 are respectively tightly stretched on the top of both sides of the C-shaped spring limiting step 22. When the spring clamp 2 is inserted into the circular clamping groove 12 of the liner body 1, the spring 3 is arranged between the spring clamp 2 and the circular clamping groove 12, and the two external hanging angles 31 of the spring 3 are also tightly stretched on the top of both sides of the C-shaped spring stop step 13.

[0035] In order to prevent the friction between the two outer corners 31 and the inner wall of the circular slot 12 when the spring 3 is arranged between the spring holder 2 and the circular slot 12, the outer ends of the two outer corners 31 of the spring 3 are inclined toward the radial center plane of the spring. Figure 6 and 7 As shown, the overall thickness of the spring is reduced, the problem of limited space between the spring holder and the circular slot is overcome, and the rotation of the spring holder and the spring is facilitated.

[0036] In addition, two symmetrically arranged latching protrusions 23 are provided on the inner side of the cylindrical wall of the cylindrical connecting clamp column 21, and the latching protrusions 23 are used to engage with the insertion end of the handle. Then, the latching protrusions 23 drive the spring clamp seat 2 to rotate under the external force of the handle insertion end. Under the cooperation of the C-type spring limiting step 22 and the C-type spring anti-swing step 13, the spring clamp seat 2 causes the spring 3 to be continuously tightened and the tension is continuously increased. When the external force disappears, the insertion end of the handle returns to its initial horizontal state under the action of the rebound force of the spring 3 to prevent the handle from sagging.

[0037] In order to control the rotation angle of the handle, a spring limiting protrusion 14 is also provided in the circular groove 12 of the spring seat, and the spring limiting protrusion 14 is arranged in the middle position of the C-shaped opening side of the C-shaped spring stop step 13. In this way, when the spring seat 2 drives an outer hanging angle 31 of the spring 3 to reach the position of the spring limiting protrusion 14, the spring seat 2 stops rotating. And because the spring limiting protrusion 14 is arranged in the middle position of the C-shaped opening side, the spring seat 2 can rotate to the left or right, so when the handle lining is installed on site, it can be installed arbitrarily regardless of left or right, which greatly improves the installation flexibility.

[0038] In a preferred embodiment, the clamping protrusion 23 adopts a trapezoidal clamping platform structure, and the width of the trapezoidal clamping platform structure near the top of the cylindrical connecting clamping column 21 is narrower than the width near the bottom of the cylindrical connecting clamping column 21. In other words, the end of the clamping protrusion 23 located on the outside of the lining body 1 is narrower than the end located on the inside of the lining body, so that the clamping of the handle insertion end and the spring clamping seat 2 is more stable and the handle is not prone to invalid swing. It should be noted that the outside of the lining body in this application refers to the handle insertion side, and the inside of the lining body refers to the inside of the door lock.

[0039] As a further improvement, the bottom end of the trapezoidal card platform structure is set as an elastic opening 231, which is connected to the handle insertion end, which will be more tightly and not easy to fall out, further eliminating the gap between the handle and the lining, and completely solving the problem of invalid up and down swinging of the handle.

[0040] In this embodiment, the disc structure of the spring holder 2 is provided with a plurality of film tool ejector holes 24 corresponding to the arc-shaped inverted hanging columns 211. The film tool ejector holes 24 are used to realize the molding of the arc-shaped inverted hanging columns when making the spring holder, which is convenient for production and processing.

[0041] When the above-mentioned split door lock handle lining is applied to the split door lock, it can prevent the split door lock handle and the panel lining from swinging ineffectively, and can also prevent the handle from sagging, so that it always remains horizontal in its natural state. The split door lock handle lining of the present invention solves two long-standing technical pain points in the field, greatly improves customer satisfaction, and has great consumer market potential.
