Description

Technical Field

[0001] The present invention relates to the technical field of fasteners, and in particular to a toothed slider locking device and a using method thereof. Background Art

[0002] When fixing internal components of a device, when the housing of some devices (such as a large-capacity lithium battery pack, etc.) is made of a soft material, has a certain elasticity, or the external dimensions of the device have a large floating range, the common practice is to design the fastener into a U-shaped hole structure. When the external dimensions of the device are larger or smaller, since the U-shaped hole has a certain installation margin, the position of the installation part can be appropriately adjusted to install the device.

[0003] Please refer to Figure 1 The fastener A with a U-shaped hole shown. The adjustment direction of the fastener A has a certain displacement adjustment margin through the adjustment slot. When it is necessary to pre-tighten a certain component, first make the end face of the fastener A as close as possible to the device. However, only when the external housing of the device undergoes a certain elastic deformation can the device be pressed tightly. It is difficult to ensure firm pre-tightening only by the manual approach. And since the opening of the adjustment slot is a U-shaped hole, the relative contact area of the screw is reduced, and the locking and fastening effect of the screw becomes poor. In the subsequent long-term vibration environment, it may loosen and fall off. Summary of the Invention

[0004] The technical problem to be solved by the present invention is as follows: When fixing and locking a device with a soft outer shell or a large floating range of external dimensions, it is possible to achieve a large installation adjustment margin, ensure firm pre-tightening, and ensure that the device is firmly locked and does not loosen even in a harsh vibration working environment, thereby improving the reliability of the normal operation of the device.

[0005] To solve the above technical problems, the present invention provides the following technical solutions:

[0006] A toothed slider locking device includes a base 100, a slider 200, a pre-tightening member 300, and a locking member 400; at both ends of the mutually contacting surfaces of the base 100 and the slider 200, toothed structures 1200 are provided; the slider 200 can slide unidirectionally from top to bottom on the base 100; when the locking contact surface 201 of the slider 200 is sufficiently fitted with the device to be locked, the pre-tightening member 300 pre-tightens the base 100 and the slider 200; after pre-tightening, the toothed structures 1200 of the base 100 and the slider 200 are in toothed engagement, so that the base 100 and the slider 200 are locked and stuck, and the locking member 400 passes through the base 100 to lock the slider 200, and the slider 200 no longer displaces; wherein, the sliding inclination angles α of the base 100 and the slider 200 are equal.

[0007] Advantages: The slider slides on the base, and it has a large installation adjustment margin, which can fix and lock devices with a relatively soft shell or a large floating outer dimension. After pre-tightening, the locking member locks the slider and the base, preventing the slider from moving any further and eliminating the problem of installation failure caused by environmental vibration in the later stage.

[0008] In an embodiment of the present invention, the front end of the base 100 contacts the slider 200; the front end of the base 100 includes an inclined surface 110 and a vertical surface 120 connected to the inclined surface 110; the toothed structures 1200 on the base 100 are respectively arranged at both ends of the inclined surface 110; a pair of pre-tightening bosses 130 and locking chutes 140 are further arranged on the inclined surface 110; a pair of the pre-tightening bosses 130 are located between the two toothed structures 1200; the locking chute 140 is located between the pair of pre-tightening bosses 130; and a pre-tightening hole 131 is arranged on the pre-tightening boss 130.

[0009] In an embodiment of the present invention, at the rear end of the base 100, slots are formed on the corresponding sides of the toothed structure 1200 to form two fixing slots 150, and fixing holes 151 are arranged on the fixing slots 150; the locking chute 140 is also located between the two fixing slots 150; and the pre-tightening hole 131 communicates with the fixing slot 150.

[0010] In an embodiment of the present invention, a convex portion 210 is arranged in the middle of the front end of the slider 200, and the convex portion 210 is open at the rear end of the slider 200; inside the convex portion 210, both sides are hollow to form a receiving space 211; the middle protrudes to form a locking boss 212, and a plurality of locking holes 213 are arranged on the locking boss 212; at both ends of the top surface of the convex portion 210, pre-tightening chutes 214 are arranged, and the pre-tightening chutes 214 communicate with the receiving space 211; the toothed structure 1200 on the slider 200 is located at the rear end of the slider 200 and on both sides of the convex portion 210.

[0011] In an embodiment of the present invention, the axes of the plurality of locking holes 213 are perpendicular to the major axis direction of the locking chute 140; one end of the locking member 400 passes through the locking chute 140 and is located in the locking hole 213 to lock the slider 200 at any position in the sliding stroke of the slider 200.

[0012] In an embodiment of the present invention, a pair of the pre-tightening bosses 130 are respectively located in the two receiving spaces 211; the installation adjustment margin of the slider 200 is determined by the position of the pre-tightening boss 130 in the receiving space 211, and the top surface 132 and the front end surface 133 of the pre-tightening boss 130 respectively determine the maximum and minimum strokes of the slider 200.

[0013] In an embodiment of the present invention, when the side surface of the accommodation space 211 contacts the front end surface 133 of the preloading boss 130, the stroke of the slider 200 is the largest at this time. When the top surface of the accommodation space 211 contacts the top surface 132 of the preloading boss 130, the stroke of the slider 200 is the smallest at this time. Then, the installation adjustment margin of the slider 200 is the difference between the maximum stroke L2 and the minimum stroke L1.

[0014] In an embodiment of the present invention, one end of the preloading member 300 passes through the preloading chute 214 and is located in the preloading hole 131 to preload the base 100 and the slider 200.

[0015] In an embodiment of the present invention, the major axis of the preloading chute 214 is greater than the installation adjustment margin.

[0016] In an embodiment of the present invention, the tooth pitch b of the tooth-shaped structures 1200 on the base 100 and the slider 200 is equal; and the tooth tip depth of the tooth-shaped structures 1200 on both satisfies 0.5a < c < a; where a represents the tooth tip depth of the tooth-shaped structure 1200 on the base 100, and c represents the tooth tip depth of the tooth-shaped structure 1200 on the slider 200.

[0017] In an embodiment of the present invention, the teeth of the tooth-shaped structures 1200 on both the base 100 and the slider 200, one end face of each is perpendicular to the sliding end face, and the tooth profile angle β of the tooth-shaped structures 1200 on both is an acute angle.

[0018] The present invention also provides a method for using a tooth-shaped slider locking device, including the following steps:

[0019] Place the base 100 at a suitable position to ensure that within the installation adjustment margin of the slider 200, the device to be locked can be pressed tightly. Use a fastener to pass through the fixing hole 151 on the base 100 to fix the base 100; place the slider 200 from directly above the base 100 and push the slider 200 to gradually approach the device to be locked;

[0020] The preloading member 300 sequentially passes through the preloading chute 214 of the slider 200 and the preloading hole 131 of the base 100; push the slider 200 to apply a preloading force to it. Correspondingly, rotate the preloading member 300 to apply a preloading force to it to ensure that the slider 200 moves downward smoothly;

[0021] When the locking contact surface 201 of the slider 200 is sufficiently fitted with the device to be locked, the locking member 400 sequentially passes through the locking chute 140 of the base 100 and the locking hole 213 of the slider 200 to lock the base 100 and the slider 200 together.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: The slider slides on the base, and it has a large installation adjustment margin, capable of fixing and locking devices with a relatively soft outer shell or a large floating dimension in shape. Moreover, after pre-tightening, the locking member locks the slider and the base, preventing the slider from moving further, eliminating the problem of installation failure caused by environmental vibration in the later stage, and ensuring the reliability of the installation fastening. By pre-tightening with the pre-tightening member, sufficient pre-tightening force can be generated to ensure that the device to be locked is firmly installed in place. And the structure of this device is simple and easy to replace, facilitating disassembly, assembly, and maintenance in the later stage. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] To facilitate those skilled in the art to understand the technical solution of the present invention, the technical solution of the present invention will be further described below with reference to the accompanying drawings of the specification.

[0041] The terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality" means two or more unless otherwise specifically defined.

[0042] As shown in Fig. 2, the present invention provides a tooth-shaped slider locking device, including a base 100, a slider 200, a pre-tightening member 300 and a locking member 400. Tooth-shaped structures 1200 are provided at both ends of the mutually contacting surfaces of the base 100 and the slider 200. The slider 200 can slide unidirectionally from top to bottom on the base 100. When the locking contact surface 201 of the slider 200 is sufficiently fitted with the device to be locked, the pre-tightening member 300 pre-tightens the base 100 and the slider 200. After pre-tightening, the tooth-shaped structures 1200 of the base 100 and the slider 200 are meshed with each other's teeth, so that the base 100 and the slider 200 are locked tightly. The locking member 400 passes through the base 100 to lock the slider 200, and the slider 200 no longer displaces. At this time, the pre-tightening member 300 no longer bears the main locking force. Among them, the sliding inclination angles α of the base 100 and the slider 200 are equal, as shown in Figure 11 and Figure 13 shown.

[0043] Please refer to Figures 2 to 4As shown, in an embodiment of the present invention, the front end of the base 100 contacts the slider 200. The front end of the base 100 includes an inclined surface 110 and a vertical surface 120 connected to the inclined surface 110. The toothed structures 1200 on the base 100 are respectively arranged at both ends of the inclined surface 110. A pair of pre-tightening bosses 130 and a locking chute 140 are also arranged on the inclined surface 110. The pair of pre-tightening bosses 130 are located between the two toothed structures 1200, the locking chute 140 is located between the pair of pre-tightening bosses 130, and a pre-tightening hole 131 is arranged on the pre-tightening boss 130. Among them, between the inclined surface 110 and the vertical surface 120, that is, at the bottom of the inclined surface 110, a notch 1120 is also arranged. Through the notch 1120, the slider 200 can slide out of the base 100 smoothly.

[0044] Please refer to Figures 2 to 4 As shown, in an embodiment of the present invention, at the rear end of the base 100, corresponding side surfaces of the toothed structure 1200 are grooved to form two fixing slots 150, and fixing holes 151 are arranged on the fixing slots 150. The locking chute 140 is also located between the two fixing slots 150, and the pre-tightening hole 131 communicates with the fixing slot 150. Specifically, the locking chute 140 is a waist-shaped slot.

[0045] Please refer to Figure 2 、 Figure 5 and Figure 6 As shown, in an embodiment of the present invention, a convex portion 210 is arranged in the middle of the front end of the slider 200, and the front end surface of the convex portion 210 is the locking contact surface 201. The convex portion 210 is open at the rear end of the slider 200. Inside the convex portion 210, both sides are hollow to form an accommodation space 211, and the middle protrudes to form a locking boss 212, and a plurality of locking holes 213 are arranged on the locking boss 212. The bottom of the locking boss 212 is beveled, and the inclination angle is equal to the sliding inclination angle α to avoid interfering with the sliding of the slider. At both ends of the top surface of the convex portion 210, pre-tightening chutes 214 are arranged, and the pre-tightening chutes 214 communicate with the accommodation space 211. The toothed structures 1200 on the slider 200 are located at the rear end of the slider 200 and on both sides of the convex portion 210. Specifically, the pre-tightening chutes 214 are waist-shaped slots.

[0046] Please refer to Figures 2 to 8As shown, in an embodiment of the present invention, the axes of the plurality of locking holes 213 are perpendicular to the major axis direction of the locking chute 140. One end of the locking member 400 passes through the locking chute 140 and is located within the locking hole 213, for locking the slider 200 at any position during the sliding stroke. A pair of preloading bosses 130 are respectively located within the two receiving spaces 211. One end of the preloading member 300 passes through the preloading chute 214 and is located within the preloading hole 131, for preloading the base 100 and the slider 200. The installation adjustment margin of the slider 200 is determined by the position of the preloading boss 130 within the receiving space 211. The top surface 132 and the front end surface 133 of the preloading boss 130 respectively determine the maximum and minimum strokes of the slider 200.

[0047] Please refer to Figures 2 to 10 As shown, in an embodiment of the present invention, when the side surface of the receiving space 211 contacts the front end surface 133 of the preloading boss 130, the stroke of the slider 200 is at its maximum at this time. When the top surface of the receiving space 211 contacts the top surface 132 of the preloading boss 130, the stroke of the slider 200 is at its minimum at this time. Then, the installation adjustment margin of the slider 200 is the difference between the maximum stroke L2 and the minimum stroke L1. To ensure that the slider 200 slides within the stroke range, the major axis of the preloading chute 214 is greater than the installation adjustment margin.

[0048] Please refer to Figures 2 to 6 、 Figures 11 to 16 As shown, in an embodiment of the present invention, to ensure the smooth meshing of the tooth-shaped structures 1200 on the base 100 and the slider 200, the tooth pitch b of the tooth-shaped structures 1200 on the base 100 and the slider 200 is equal. And the tooth tip depth of the tooth-shaped structures 1200 on both of them satisfies 0.5a < c < a. Wherein, a represents the tooth tip depth of the tooth-shaped structure 1200 on the base 100, and c represents the tooth tip depth of the tooth-shaped structure 1200 on the slider 200. The teeth of the tooth-shaped structures 1200 on the base 100 and the slider 200, one end face of each is perpendicular to the sliding end face. The tooth profile angle β of the tooth-shaped structures 1200 on both of them is an acute angle. When the slider 200 is preloaded, for each tooth it slides, the horizontal displacement value is S2, and the horizontal displacement increment after locking is S1. If the tooth pitch of the tooth-shaped structure 1200 on the base 100 is less than the tooth pitch of the tooth-shaped structure 1200 on the slider 200, it will cause the tooth-shaped structure 1200 on the base 100 to contact and interfere with the tooth-shaped structure 1200 on the slider 200 in advance before meshing, thereby causing a gap between the base 100 and the slider 200 and preventing them from meshing smoothly. See Figure 17 As shown.

[0049] Please refer to Figures 2 to 18 As shown, the present invention also provides a method of using a tooth-shaped slider locking device, including the following steps:

[0050] Place the base 100 in a suitable position to ensure that the device to be locked can be pressed within the installation adjustment margin of the slider 200, and use fasteners to pass through the fixing holes 151 on the base 100 to fix the base 100. Insert the slider 200 from directly above the base 100, and push the slider 200 gradually close to the device B to be locked.

[0051] The pre-tightening member 300 passes through the pre-tightening slot 214 of the slider 200 and the pre-tightening hole 131 of the base 100 in sequence. The slider 200 is pushed to be pre-tightened, and correspondingly, the pre-tightening member 300 is rotated to pre-tighten it, ensuring that the slider 200 moves downward smoothly.

[0052] When the locking contact surface 201 of the slider 200 is sufficiently fitted with the device B to be locked, the locking member 400 passes through the locking slot 140 of the base 100 and the locking hole 213 of the slider 200 in sequence to lock the base 100 and the slider 200 .

[0053] If it is to be removed, just loosen or tighten the fastener on the fixing hole 151 .

[0054] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention, and any reference numerals in the claims should not be regarded as limiting the claims involved.
