Description

Technical Field

[0001] The invention relates to the technical field of door body testing devices, in particular to a simple durability testing device for a push-to-open door opener. Background Art

[0002] Push-pop door refers to a type of door that will automatically pop outward and open or move inward to close after an external force acts on the door. Push-pop door requires a push-pop door opener to open and close the door. The direction of the external force acting on the door is generally perpendicular to the door, or the direction of the component force generated by the external force can be perpendicular to the door, so that the door pops outward to open the door or rotates inward to close the door. Push-pop door can be applied to many scenes in our daily work and life, such as cabinet doors for home use. When the cabinet door is in the closed state, external force presses on the cabinet door, and the cabinet door can automatically pop outward and flip outward in a certain arc to open the cabinet door; conversely, when the cabinet door is in the open state, external force pushes the cabinet door, causing the cabinet door to flip inward in a certain arc, and then press the cabinet door again to reset the cabinet door and connect it to the cabinet body, thereby closing the cabinet door.

[0003] The door body can be opened and closed by pressing a button, which depends on the push-type door opener. The performance of the push-type door opener is related to the service life of the door body. Therefore, it is necessary to conduct durability tests on the push-type door opener, especially to simulate the performance of the push-type door opener under the actual use state of the door body, including the maximum total number of opening and closing times of the door body that can be maintained under normal use and the number of opening and closing times of each door body opening and closing. In other words, it is necessary to test the number of opening and closing times and the opening and closing speed of the door body under the function of the push-type door opener, so as to test the durability of the push-type door opener.

[0004] For the durability test of push-to-open door openers, the existing technology generally uses dedicated test equipment, which is bulky and expensive, and difficult to be widely deployed among customers. Therefore, a durability test device that can simulate real usage scenarios and has a simple structure and low cost is needed. Summary of the invention

DETAILED DESCRIPTION

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments: like Figure 1-Figure 5 As shown, this embodiment provides a simple durability test device for a push-type door opener, including a fixed platform 8, a driving component, a sliding component, a pressing component, a door closing component and an advance and retreat transmission component, the driving component is connected to the sliding component, and is used to drive the sliding component to perform linear reciprocating motion, and the sliding component is fixedly or detachably mounted on the fixed platform 8. The driving component can be mounted on the fixed platform 8 or on an external supporting surface, for example, the driving component can be mounted on a desktop, a wall, a ground or other locations.

[0025] The forward and backward transmission assembly is installed on the sliding assembly, so that the forward and backward transmission assembly can perform linear reciprocating motion together with the sliding assembly under the drive of the driving assembly. The forward and backward transmission assembly includes a fixed part and a movable part.

[0026] One end of the door closing assembly is connected to the fixed part of the forward and backward transmission assembly, and the other end is a free end, that is, the other end of the door closing assembly does not need to be connected to any components and is not restricted or constrained.

[0027] One end of the pressing component is connected to the movable part of the forward and backward transmission component, and the other end is a free end, that is, the other end of the pressing component does not need to be connected to any components and is not restricted or constrained.

[0028] The fixed part and the movable part cooperate with each other, so that when the sliding assembly drives the advance and retreat transmission assembly to perform linear reciprocating motion, the pressing assembly performs reciprocating motion in a direction perpendicular to the linear reciprocating motion, so that the pressing assembly approaches or moves away from the target door body 18 in the closed state. The fixed part and the movable part cooperate with each other, so that when the sliding assembly drives the advance and retreat transmission assembly to perform linear reciprocating motion, the door closing assembly maintains a constant position in a direction perpendicular to the linear reciprocating motion, that is, the distance from the target door body 18 in the closed state in the direction perpendicular to the linear reciprocating motion remains unchanged, and the door closing assembly only performs linear reciprocating motion in a direction parallel to the linear reciprocating motion.

[0029] The pressing component and the door closing component are arranged at an angle, and the angle is an acute angle. The pressing component is perpendicular to the movement direction of the sliding component to perform linear reciprocating motion.

[0030] The pressing component is used to generate a pressing force on the target door body 18, so that the door panel door body can be opened under the pressure of the force. The closing component is used to generate a force on the target door body 18 in the open state, and the force can drive the target door body 18 to rotate in the closing direction to close the door. The pressing component and the closing component cooperate with each other to achieve repeated closing and opening operations on the target door body 18.

[0031] The reason why the pressing component is set to be perpendicular to the direction of motion of the sliding component performing linear reciprocating motion, and the door closing component and the pressing component are set at an angle, is that the pressing component can press the target door body 18 in the closed state in a vertical direction, so as to open the target door body 18. During the opening process of the target door body 18, before the target door body 18 contacts the door closing component, the door closing component will not interfere with the target door body 18, that is, it will not block the opening process of the target door body 18, so as to ensure that the target door body 18 opens to the preset position. At the same time, when the opened target door body 18 reaches the preset position (which can be fully opened or partially opened), the target door body 18 can contact the door closing component, so that the door closing component can push the target door body 18 in the open state to rotate in the closing direction again to achieve closing.

[0032] In actual use, the pressing component also starts to perform linear reciprocating motion in a non-vertical direction but close to vertical direction to press the target door body 18. Close to vertical means that it forms a certain angle with the vertical direction, and the angle is an acute angle. The range of the angle can be limited by a preset threshold to avoid excessive deviation. That is, any linear reciprocating motion direction is acceptable as long as the pressing component can press the target door body 18 and open the target door body 18.

[0033] Among them, the sliding assembly performs a linear reciprocating motion, and the sliding assembly drives the door closing assembly and the pressing assembly through the forward and backward transmission assembly to realize an opening and closing operation of the target door body 18. The sliding assembly completes a linear reciprocating motion, including completing a motion moving along a first direction and a motion moving along a second direction, and the first direction and the second direction are just opposite. For example, the first direction is the forward direction, and the second direction is the backward direction. When the sliding assembly moves in the first direction, the sliding assembly drives the pressing assembly to act on the target door body 18 to perform a pressing operation, so that the target door body 18 opens, and when the sliding assembly reaches the movement limit position of the first direction or before, the target door body 18 contacts the door closing assembly. Conversely, when the sliding assembly moves in the second direction, the sliding assembly drives the door closing assembly to push the target door body 18 to rotate in the door closing direction, so that the target door body 18 is closed, and when the sliding assembly reaches the movement limit position of the second direction or before, the target door body 18 contacts the pressing assembly. In this way, as the sliding component continuously performs linear reciprocating motion, the sliding component can drive the door closing component and the pressing component to repeatedly perform door opening and door closing operations on the target door body 18, thereby simulating the actual use scenario of pressing to open and close the door.

[0034] Exemplarily, the fixed platform 8 can be a component of the simplified durability test device for the push-type door opener itself, that is, a component of the simplified durability test device for the push-type door opener, or can be an external component, that is, replaced by an external support surface, for example, the table top of the test workbench is used as the fixed platform 8. The fixed platform 8 plays the role of installing related components such as the sliding component. When replaced by an external support surface, the related components such as the sliding component only need to be installed on the external support surface.

[0035] Exemplarily, the driving assembly includes a driving part, a connecting block 5 and a connecting push rod 6, wherein the output end of the driving part is connected to one end of the connecting push rod 6, and the driving part is used to drive the connecting push rod 6 to perform linear reciprocating motion. The other end of the connecting push rod 6 is connected to the connecting block 5, and the connecting block 5 is connected to the sliding assembly. The driving part drives the connecting push rod 6 to perform linear reciprocating motion, and the connecting push rod 6 drives the sliding assembly to perform linear reciprocating motion through the connecting block 5.

[0036] The driving part may be a linear module or a cylinder or other device that can output linear motion.

[0037] Exemplarily, the sliding assembly includes a slide rail 7 and a push rod plate 4, the slide rail 7 is fixedly or detachably mounted on a fixed platform 8, the push rod plate 4 is slidably mounted on the slide rail 7, and the push rod plate 4 is perpendicular to the fixed platform 8. The connecting block 5 is fixedly or detachably connected to the push rod plate 4, so that the driving assembly is connected to the sliding assembly. The connecting block 5 is mounted on one side end surface of the push rod plate 4.

[0038] The slide rail 7 is fixedly mounted at the edge of the top surface of the fixing platform 8 , so that the push rod plate 4 is also located at the edge of the fixing platform 8 .

[0039] The advance and retreat transmission assembly is connected to the push rod plate 4, so that the advance and retreat assembly is installed on the sliding assembly. Wherein, the fixed part of the advance and retreat assembly is connected to the push rod plate 4.

[0040] Exemplarily, the forward and backward transmission assembly includes a sleeve box 3, a first connecting column 2, a driving wheel 15, a force frame 14 and an elastic component. The sleeve box 3 is fixedly or detachably mounted on the push rod plate 4, and the sleeve box 3 and the connecting block 5 are respectively located on the end surfaces of the two opposite sides of the push rod plate 4. The driving wheel 15 is located in the cavity of the sleeve box 3, and at least a part of the driving wheel 15 is exposed outside the cavity, so that the driving wheel 15 is in contact with the force frame 14 located outside the sleeve box 3. The driving wheel 15 is installed in the sleeve box 3 through the first connecting column 2, and the driving wheel 15 can rotate around the first connecting column 2. When the sliding assembly performs a linear reciprocating motion, the push rod plate 4 drives the sleeve box 3 to perform a linear reciprocating motion. Since the driving wheel 15 is in contact with the force frame 14, the force frame 14 is subjected to the reaction force of the elastic component, so that the driving wheel 15 follows the push rod plate 4 to perform a linear reciprocating motion, and generally rotates around the first connecting column 2.

[0041] The pressing assembly is connected to one end of the force-bearing frame 14 away from the driving wheel 15 , and the door closing assembly is connected to the sleeve box 3 .

[0042] One end of the elastic component is connected to the force-bearing frame 14, and the other end is fixedly connected to the pressing component or other positions.

[0043] Exemplarily, the door closing assembly is also connected to the sleeve 3 through the first connecting column 2, and the first connecting column 2 passes through the door closing assembly, the upper cover of the sleeve 3 and the driving wheel 15 in sequence. One end of the first connecting column 2 passes through the driving wheel 15 and is fixed on the lower cover of the sleeve 3. The upper cover and the lower cover of the sleeve 3 surround the cavity of the sleeve 3.

[0044] The first connecting column 2 passes through the center of the driving wheel 15 , that is, passes through the center of the circle of the driving wheel 15 .

[0045] Since the door closing assembly is fixedly connected to the sleeve box 3, the door closing assembly does not rotate relative to the sliding assembly when following the sliding assembly to make linear reciprocating motion, so that the distance between the door closing assembly and the push rod plate 4 in the direction perpendicular to the linear reciprocating motion does not change.

[0046] The end surface where the force-bearing frame 14 abuts the driving wheel 15 is a convex curved surface, and the convex direction of the convex curved surface is toward the driving wheel 15 , that is, the end surface where the force-bearing frame 14 abuts the driving wheel 15 is convexly arranged in the direction of the driving wheel 15 . During the process of the driving wheel 15 following the sliding assembly to make a linear reciprocating motion, the driving wheel 15 can reach different positions of the convex curved surface. Since the driving wheel 15 reciprocates along a straight line, that is, the distance between the driving wheel 15 and the push rod plate 4 in a direction perpendicular to the linear reciprocating motion does not change, the driving wheel 15 will form a process difference when it reaches different positions of the convex curved surface, so that the driving wheel 15 can drive the force frame 14 away from or close to the sliding assembly, that is, the force frame 14 also makes a linear reciprocating motion in a direction perpendicular to the linear reciprocating motion, so that the force frame 14 moves away from or close to the push rod plate 4 in a direction perpendicular to the push rod plate 4, and then the force frame 14 drives the pressing assembly to move away from or close to the push rod plate 4 in a direction perpendicular to the push rod plate 4, and then the pressing assembly moves close to or away from the target door body 18 in a direction perpendicular to the target door body 18 in the closed state, so that the pressing assembly can apply a pressing force to the target door body 18 in a vertical direction.

[0047] When the force frame 14 is moving away from the push rod plate 4, the elastic component is deformed and in a compression process; when the force frame 14 is moving closer to the push rod plate 4, the elastic component is deformed and in a tension process. By using the elastic component, the driving wheel 15 can reach different positions of the convex surface of the force frame 14, and the force frame 14 can be driven to move away from and closer to the push rod plate 4.

[0048] Among them, the sleeve box 3, the first connecting column and the driving wheel 15 constitute the fixed part of the forward and backward driving assembly, the force frame 14 constitutes the movable part of the forward and backward driving assembly, the movable part is installed on the fixed part, and the movable part cooperates with the fixed part so that the fixed part only follows the sliding assembly to make a linear reciprocating motion, and the movable part only makes a linear reciprocating motion in a direction perpendicular to the linear reciprocating motion.

[0049] Exemplarily, the pressing assembly includes a push rod 12, which is in a straight line shape. One end of the push rod 12 is connected to an end of the force frame 14 away from the driving wheel 15, and the other end of the push rod 12 is a free end.

[0050] Exemplarily, a flexible portion is further provided on the other end of the push rod 12, and the flexible portion comprises a flexible material. Through the flexible portion, the push rod 12 can form a certain buffer when pressing the target door body 18 to avoid damage to the target door body 18.

[0051] Exemplarily, the door closing assembly includes a door closing hanging plate 1, which is in the shape of a straight line, one end of which is connected to the sleeve box 3, and the other end is a free end.

[0052] Exemplarily, the door closing assembly further includes a rod 17, which is fixedly mounted on the free end of the door closing hanging plate 1, and the rod 17 is vertically connected to the door closing hanging plate 1. A flexible portion is also provided on the rod 17, and the flexible portion includes a flexible material, so that a certain buffer can be formed when the door closing assembly contacts the target door body 18 to avoid damage to the target door body 18.

[0053] Exemplarily, the elastic component is a spring 13, one end of which is fixedly connected to the end of the force frame 14 away from the driving wheel 15, that is, the spring 13 and the push rod 12 are connected to the same end of the force frame 14. The other end of the spring 13 is fixed to the push rod 12. Of course, one end of the spring 13 can also be fixed to an external position, and the other end can be connected to the force frame 14 or the push rod 12, as long as it is ensured that the force frame 14 can be repeatedly moved close to and away from the push rod plate 4 under the mutual cooperation of the spring 13 and the driving wheel 15.

[0054] In the above example, the force frame 14 with a convex curved surface cooperates with the driving wheel 15 to form a process difference, so that the driving wheel 15 can drive the force frame 14 to approach or move away from the target door body 18 in the closed state. As another example, an eccentric wheel and a flat force frame 14 can also be used to cooperate. The eccentric wheel rotates to different positions, and the length of the part of the eccentric wheel protruding from the cavity of the sleeve 3 is different, so that even if the end surface of the force frame 14 abutting against the eccentric wheel is a flat surface, the eccentric wheel can drive the force frame 14 to approach or move away from the target door body 18 in the closed state. Among them, the first connecting column 2 passes through the eccentric part of the eccentric wheel, that is, through the non-center part.

[0055] Exemplarily, the simplified durability test device of the push-type door opener further includes a deflection component, which is located on the path of movement of the pressing component, that is, on the path of movement of the pressing component in a direction perpendicular to the linear reciprocating motion of the sliding component. The deflection component is used to drive the pressing component to deviate from the original moving path at a preset angle, so that the pressing component deviates from one side of the original moving path. The purpose of the deflection component driving the pressing component to deviate from the original moving path is that, during the process of the door closing component driving the target door body 18 to close, the pressing component will not block the target door body 18 from being fully opened or fully closed due to reaching the extreme position away from the sliding component, that is, avoiding mutual interference between the target door body 18 and the pressing component during the opening or closing process, thereby achieving the effect of fully opening or fully closing the target door body 18.

[0056] Exemplarily, the deflection assembly includes a guide wheel 11 and a deflection groove 121, the guide wheel 11 is located on the moving path of the pressing assembly, the deflection groove 121 is located on the pressing assembly, the opening of the deflection groove 121 faces the guide wheel 11, the guide wheel 11 can slide into or out of the deflection groove 121, when the guide wheel 11 is completely located in the deflection groove 121, the pressing assembly remains in the original moving path, when the guide wheel 11 is partially or completely located outside the deflection groove 121, the pressing assembly deviates from the original moving path.

[0057] Exemplarily, the simplified durability testing device for the push-to-open door opener further includes a guide assembly, on which the pressing assembly is located, and the guide assembly is used to guide the pressing assembly by being limited to the pressing assembly.

[0058] The guide assembly includes a base plate 10 and two limit bars 9, the two limit bars 9 are installed on the base plate 10, the two limit bars 9 are arranged in parallel and spaced apart, the two limit bars 9 and the base plate 10 together form a guide groove 16, the pressing assembly is located in the guide groove 16, the pressing assembly can slide along the guide groove 16, so that the pressing assembly slides along the extension direction of the guide groove 16 to achieve a guiding effect.

[0059] Among them, the lateral width of the guide groove 16 is greater than the lateral width of the pressing assembly, that is, the lateral width of the guide groove 16 is greater than the lateral width of the push rod 12, so that when the push rod 12 moves along the guide groove 16, when the guide wheel 11 deflects the push rod 12, the push rod 12 can deviate from one side of the original moving path and the push rod 12 is still located in the guide groove 16.

[0060] The guide wheel 11 is mounted on the bottom plate 10. The guide wheel 11 can be mounted on the bottom plate 10 through a second connecting column 111. The guide wheel 11 can rotate or be prohibited from rotating. One end of the spring 13 as an elastic component can be fixedly mounted on the bottom plate 10, and the other end is connected to the push rod 12. The force frame 14 is slidably mounted on the bottom plate 10.

[0061] Exemplarily, the fixed platform 8, connecting block 5, push rod plate 4, sleeve box 3, first connecting column 2, second connecting column 111, door closing hanging plate 1, push rod 12, bottom plate 10, limit strip 9, force frame 14, etc. are all made of wood to save material cost.

[0062] In actual use, the driving assembly drives the push rod plate 4 to perform linear reciprocating motion on the slide rail 7. Assuming that from left to right is the first direction and from right to left is the second direction, at the starting position, the driving wheel 15 is located on one side of the force-bearing frame 14 or just abuts against the left side of the force-bearing frame 14. Starting from the starting position, the push rod plate 4 drives the driving wheel 15 to move from the left side of the force frame 14 to the right side. Since the end face of the force frame 14 is a convex curved surface, the driving wheel 15 reaches the middle position of the force frame 14 (that is, the most convex position) from the left side of the force frame 14. The driving wheel 15 gradually moves the push rod 12 connected to the force frame 14 away from the push rod plate 4. When the driving wheel 15 reaches the middle position of the force frame 14, the push rod 12 reaches the extreme position close to the target door body 18 and completes the pressing of the target door body 18, so that the target door body 18 opens, and the opening direction of the target door body 18 is exactly toward the direction of the door closing assembly, that is, the target door body 18 rotates toward the direction of the door closing assembly. When the driving wheel 15 continues to move from the middle position of the force frame 14 to the right side of the force frame 14, the push rod 12 moves toward the target door body, and synchronously, the target door body 18 rotates toward the door closing hanging plate 1. When or before the driving wheel 15 reaches the right side, the target door body 18 contacts the rod 17 on the door closing hanging plate 1. Then, the driving wheel 15 moves along the second direction, that is, from the right side to the left side of the force frame 14. Similarly, when the driving wheel 15 moves from the right side to the middle position of the force frame 14, the push rod 12 moves away from the push rod plate 4. Synchronously, the target door body 18 moves away from the door closing hanging plate 1 and toward the door closing direction. When or before the push rod 12 reaches the limit position away from the push rod plate 4, the target door body 18 reaches the door closing position, so that the push rod 12 is located on a side perpendicular to the target door body 18, and the push rod 12 can press the target door body 18, so that the target door body 18 is pressed next time and opened, and enters the next cycle.

[0063] Among them, during the opening process of the target door body 18 toward the door closing hanger 1 and the closing process of the target door body 18 toward the door closing hanger 1, the guide wheel 11 deflects the push rod 12, so that the push rod 12 can avoid the target door body 18 during the rotation process, avoid interfering with the target door body 18, and ensure that the target door body 18 can be fully opened and fully closed.

[0064] When the driving assembly continuously drives the driving wheel 15 to move back and forth, the target door body 18 can be opened and closed periodically, so that the durability test of the push-to-pop door opener on the target door body 18 can be performed to detect the performance and service life of the push-to-pop door opener.

[0065] Among them, by controlling the working time of the driving component and the moving speed of the driving wheel 15, the opening and closing times and opening and closing speed of the target door body 18 can be simulated, that is, the opening and closing times and opening and closing speed of the push-to-pop door opener can be simulated.

[0066] The present invention has a simple structure, is easy to maintain, and is low in cost, and can be widely promoted and used. It can complete the test of the push-to-pop door opener with performance comparable to that of a dedicated durability test device, including the test of controllable opening and closing times and opening and closing speeds.

[0067] The embodiment disclosed in this specification is only an example of a unilateral feature of the present invention, and the protection scope of the present invention is not limited to this embodiment, and any other functionally equivalent embodiments fall within the protection scope of the present invention. For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the protection scope of the claims of the present invention.
