[0070] The embodiments of the present application will be described below with reference to the accompanying drawings.

[0071] The embodiment of the present application provides an installation device for inserting a product into a guide rail. Figure 1 It is a schematic diagram of the installation device of an embodiment of the present application clamping a product into a guide rail.

[0072] like Figure 1 As described, the mounting device 1 of the embodiment of the present application is fixed to the product 2, and can be used to clip the product 2 into the guide rail 3. The product described in the embodiment of the present application can be an electrical product such as a PLC module, or other products, and the embodiment of the present application does not limit this. In addition, the guide rail 3 of the embodiment of the present application can be a DIN rail, or other standard rails, and the embodiment of the present application does not limit this.

[0073] In addition, for the convenience of explanation, Figure 1 The direction of the x-axis (+x, -x) shown is called the "front-rear direction", the direction of the y-axis (+y, -y) is called the "up-down direction", and the direction of the z-axis (-z, +z) is called the "left-right direction". Those skilled in the art should understand that the "up", "down", "left", "right", "front", and "back" described in the embodiments of the present application are used to illustrate the relative positions of different elements and should not be understood as limitations on actual applications.

[0074] Figure 2 is a schematic diagram of the installation device of the embodiment of the present application observed from one angle, Figure 3 It is a schematic diagram of the installation device of the embodiment of the present application observed from another angle.

[0075] like Figure 2 and Figure 3As shown, the installation device 1 includes a pressing portion 10, an upper clamping rod 11, a lower clamping rod 12, a first linkage portion 13, and a second linkage portion 14. The pressing portion 10 can move along the front-to-back direction (x+, x-), the upper clamping rod 11 extends along the up-down direction (y+, y-) and at least a part is located on the upper side of the pressing portion 10, the lower clamping rod 12 extends along the up-down direction and at least a part is located on the lower side of the pressing portion 10, the first linkage portion 13 is arranged on one side of the pressing portion 10 in the left-right direction, and connects the pressing portion 10 and the upper clamping rod 11, the second linkage portion 14 is arranged on the other side of the pressing portion 10 in the left-right direction, and connects the pressing portion 10 and the lower clamping rod 12. In addition, Figure 2 and Figure 3 In the figure, the first linkage part 13 is arranged on the left side (-z) of the pressing part 10, and the second linkage part 14 is arranged on the right side (+z) of the pressing part 10. However, the embodiments of the present application are not limited to this. The first linkage part 13 can also be arranged on the right side of the pressing part 10, and the second linkage part 14 can be arranged on the left side of the pressing part 10.

[0076] In the embodiment of the present application, when the pressing portion 10 presses the guide rail 3 in the front-rear direction, the first linkage portion 13 moves the upper clamping rod 11 downward (-y), and the second linkage portion 14 moves the lower clamping rod 12 upward (+y). Figure 1 As shown, the upper clamping rod 11 and the lower clamping rod 12 clamp the guide rail 3 in the up and down directions.

[0077] Therefore, by setting a linkage part between the pressing part and the upper and lower clamping rods, the linkage part allows the upper and lower clamping rods to move relatively to clamp the guide rail while the pressing part is pressed against the guide rail, so that the product can be clamped into the guide rail with one hand through a simple structure.

[0078] In some embodiments, Figure 2 As shown, the first linkage portion 13 includes a first guide block 131 and a first guide portion 132, the first guide block 131 is slidably connected to the first guide portion 132, and the first guide block 131 is arranged on one side of the pressing portion 10 in the left-right direction ( Figure 2 The first guide portion 132 is disposed on the upper clamping rod 11, and the first guide portion 132 is moved upward and away from the guide rail 3 (such as Figure 1 When the mounting device 1 is in the initial state (i.e., the upper clamping rod 11 is located at the uppermost position and the lower clamping rod 12 is located at the lowermost position), the first guide block 131 is located at the bottom of the first guide portion 132. When the pressing portion 10 presses the guide rail 3, the first guide block 131 moves forward (+x) relative to the first guide portion 132, thereby having a tendency to move upward in the first guide portion 132. Since the pressing portion 10 can only move in the front-to-back direction, the upper clamping rod 11 moves downward relative to the pressing portion 10 under the linkage action of the first linkage portion 13.

[0079] like Figure 3 As shown, the second linkage portion 14 includes a second guide block 141 and a second guide portion 142, the second guide block 141 and the second guide portion 142 are slidably connected, and the second guide block 141 is arranged on the other side of the pressing portion 10 in the left-right direction ( Figure 3 The second guide portion 142 is arranged on the lower clamping rod 12, and the second guide portion 142 is arranged along the lower and away from the guide rail 3 (such as Figure 1 When the installation device 1 is in the initial state, the second guide block 141 is located at the top of the second guide portion 142. When the pressing portion 10 presses the guide rail 3, the second guide block 141 moves forward (+x) relative to the second guide portion 142, so that there is a tendency to move downward in the second guide portion 142. Since the pressing portion 10 can only move in the front-to-back direction, the lower clamping rod 12 moves upward relative to the pressing portion 10 under the linkage of the second linkage portion 14. Therefore, the operation of fixing the installation device to the guide rail by pressing the guide rail with one hand is realized through the first linkage portion and the second linkage portion.

[0080] In addition, optional, such as Figure 2 and Figure 3 As shown, the first guide block 131 and the second guide block 141 are cylindrical protrusions, and the first guide portion 132 and the second guide portion 142 are arc-shaped guide grooves that slide with the cylindrical protrusions. Thus, smooth sliding can be achieved. In addition, other shapes of cylindrical protrusions and grooves can also be used, and the embodiments of the present application are not limited to this.

[0081] In addition, the first linkage part and the second linkage part are described above using the columnar protrusion and the guide groove as an example, but the embodiments of the present application are not limited to this. For example, connecting rods, gears and other components can also be used as long as the structure can realize the linkage between the forward and backward movement of the pressing part and the upward and downward movement of the upper and lower clamping rods.

[0082] Figure 4 This is a cross-sectional view for explaining the structure in which the pressing portion moves in the front-rear direction.

[0083] like Figure 4 As shown, the pressing part 10 is provided with a first limiting part 101 extending in the front-to-back direction, and the housing of the product 2 is provided with a second limiting part 210 extending in the front-to-back direction. The first limiting part 101 and the second limiting part 210 cooperate to limit the pressing part 10 to be movable only in the front-to-back direction. Figure 4As shown, the first limiting portion 101 includes at least one limiting hole, and the second limiting portion 210 includes at least one limiting column respectively matched with the at least one limiting hole. However, the embodiment of the present application is not limited thereto, and the first limiting portion 101 may also include at least one limiting column, and the second limiting portion 210 may include at least one limiting hole respectively matched with the at least one limiting column. In addition, Figure 4 In the figure, two limiting posts and two limiting holes are used as an example, but the embodiment of the present application is not limited thereto. For example, one limiting hole and one limiting post may be provided, the limiting hole extends in the front-to-back direction and is formed as a long hole in the up-down direction, and the limiting post is formed into a shape matching the limiting hole. Thus, the freedom of the pressing part 10 may be limited by one limiting hole and one limiting post.

[0084] In some embodiments, Figure 1 As shown, the guide rail 3 may be a DIN guide rail, and the guide rail 3 has an upper flange 31 and a lower flange 32. Figure 4 As shown, the pressing portion 10 faces the guide rail 3 ( Figure 4 The end of the guide rail 3 ( Figure 4 The upper flange 31 (not shown) Figure 4 not shown) and the lower flange 32 ( Figure 4 The step portion 102 abuts against the surface of the substrate (not shown).

[0085] like Figure 1 As shown, the upper clamping rod 11 includes a first rod component 111 fixed to the outer shell of the product 2 and a second rod component 112 connected to the first rod component 111 and located on one side of the pressing portion 10 in the left-right direction. The connection between the first rod component 111 and the second rod component 112 is provided with a groove 113 that is engaged by the upper flange 31. The lower clamping rod 12 includes a third rod component 121 abutting against the outer shell of the product 2 and a fourth rod component 122 (as shown in FIG. 1 ) connected to the third rod component 121 and located on the other side of the pressing portion 10 in the left-right direction. Figure 3 As shown in FIG. 1 , a groove 123 is provided at the connection between the third rod member 121 and the fourth rod member 122, into which the lower flange 32 is clamped. Thus, the guide rail 3 is clamped by the groove 113 and the groove 123 of a simple structure.

[0086] Optional, such as Figure 2 As shown, the first rod member 111 has a first elastic arm 114 extending in the up-down direction. Figure 1 As shown, the upper end of the first elastic arm 114 has a protrusion 115 facing the shell side of the product 2, and the shell of the product 2 is provided with a wave-shaped slide groove 21 (as shown in FIG. 2 ) extending in the up-down direction and cooperating with the protrusion 115. Figure 4As shown in FIG. 1 , as the upper clamping rod 11 moves up and down, the protrusion 115 can slide in the slide groove 21 and be fixed in the recess of the slide groove 21 , thereby fixing the upper clamping rod 11 on the product 2 .

[0087] Optional, such as Figure 1 As shown, the third rod member 121 includes a second elastic arm 124 extending in the up-down direction, the lower end of the second elastic arm 124 is inclined toward the housing side of the product 2, and the housing of the product 2 is provided with a plurality of inclined surfaces 22 abutting against the lower end of the second elastic arm 124. The inclined surface closer to the upper side has a larger angle with the up-down direction. For example, Figure 1 As shown in the partial enlarged view in FIG, the inclined surface 22-1 is closer to the upper side than the inclined surface 22-2, and the angle between the inclined surface 22-1 and the up-down direction (y-axis direction) is θ1, and the angle between the inclined surface 22-2 and the up-down direction is θ2, and θ1 is greater than θ2. Therefore, as the lower clamping rod 12 moves up and down, the lower end of the second elastic arm 124 moves along the inclined surface, and when the lower clamping rod 12 moves upward to the position of clamping the guide rail 3, the lower end of the second elastic arm 124 is closer to vertical contact with the inclined surface on the upper side (for example, the inclined surface 22-2), so that the second elastic arm 124 applies force to the connection between the third rod member 121 and the fourth rod member 122, so that the groove 123 further clamps the lower flange 32 of the guide rail 3.

[0088] Combine the following Figures 1 to 4 The process of fixing the product 2 to the guide rail 3 using the installation device 1 of the embodiment of the present application is described. Those skilled in the art should understand that the following description is only to make the structure of the installation device 1 of the embodiment of the present application clearer and should not be regarded as a limitation on the implementation method of the installation device 1 of the embodiment of the present application.

[0089] When the installation device 1 is in the initial state, that is, the upper clamping rod 11 is located at the uppermost position (it can also be said that the upper clamping rod 11 is in the pulled-up state), the lower clamping rod 12 is located at the lowermost position, the pressing part 10 is located at the rearmost position, the first guide block 131 of the first linkage part 13 is located at the lowermost side of the first guide part 132, and the second guide block 141 of the second linkage part 14 is located at the uppermost side of the second guide part 142. Then the operator can hold the front end of the product 2 with one hand and make the step portion 102 of the pressing part 10 abut against the guide rail 3 and press the guide rail 3 backwards, and the pressing part 10 moves forward under the reaction force of the guide rail 3, and drives the first guide block 131 and the second guide block 141 to move forward, so that the first guide block 131 has a tendency to move upward in the first guide part 132, and the second guide block 141 has a tendency to move downward in the second guide part 142. Since the pressing portion 10 can only move in the front-to-back direction, as the first guide block 131 continues to move forward, the first guide portion 132 passively moves downward relative to the first guide block 131, thereby driving the upper clamping rod 11 to move downward relative to the pressing portion 10. At the same time, the protrusion 115 at the upper end of the first elastic arm 114 slides downward along the wavy groove 21 on the outer shell of the product 2 until the first guide portion 132 moves to the lowest side relative to the first guide block 131, and the upper flange 31 of the guide rail 3 is inserted into the groove 113 of the upper clamping rod 11, and the protrusion 115 slides and is fixed in the depression of the groove 21, thereby realizing the position locking of the upper clamping rod 11; The second guide block 141 continues to move forward, and the second guide portion 142 passively moves upward relative to the second guide block 141, thereby driving the lower clamping rod 12 to move upward relative to the pressing portion 10. At the same time, the lower end of the second elastic arm 124 slides upward along the inclined surface 22 until the second guide portion 142 moves to the uppermost side relative to the second guide block 141, and the lower flange 32 of the guide rail 3 is inserted into the groove 123 of the lower clamping rod 12. The lower end of the second elastic arm 124 abuts against the uppermost inclined surface 22-1, and applies force to the connection between the third rod component 121 and the fourth rod component 122, so that the groove 123 further clamps the lower flange 32 of the guide rail 3. In this way, the product 2 is installed on the guide rail 3 by one-handed operation.

[0090] In addition, when removing the product 2 from the guide rail 3, a tool can be used to pull up the upper clamping rod 11. Under the action of the first linkage part 13, the pressing part 10 is passively moved toward the rear, and under the action of the second linkage part 14, the lower clamping rod 12 is passively moved toward the lower side, thereby disengaging the installation device 1 from the guide rail 3.

[0091] According to the installation device of the embodiment of the present application, a linkage part is arranged between the pressing part and the upper and lower clamping rods. The linkage part enables the upper and lower clamping rods to move relative to each other and clamp the guide rail while the pressing part is pressed against the guide rail, thereby realizing the product being clamped into the guide rail with one hand through a simple structure.

[0092] It is worth noting that the above only describes the components or modules related to the present application, but the present application is not limited thereto. The installation device for inserting a product into a guide rail in the embodiment of the present application may also include other components or modules, and the specific contents of these components or modules may refer to the relevant technology.
