Description

BACKGROUND OF THE INVENTION Technical field

[0001] The present disclosure relates to a control box structure for connection with actuator lines and more precisely to a box structure with a semi-automatic spring opening mechanism. Description of the related area

[0002] A linear actuator for medical beds, home lift beds, fitness and rehabilitation equipment, height-adjustable tables and chairs for home use, door openers or window openers, which primarily uses a motor as a power source and transmits movement via a screw mechanism to a telescopic tube to achieve linear displacement, with an object to be moved attached to the telescopic tube and moving along with the telescopic tube.

[0003] Furthermore, the linear actuator is operated by a hand control unit, which sends control signals to a control box. This control box, in turn, controls the telescopic tube of the linear actuator to perform a linear movement. Accordingly, the control box is connected to several cables, and to protect these cables, it is typically fitted with a cable cover to shield them and prevent them from becoming loose or detached from the control box, which could cause the sliding mechanism to malfunction.

[0004] However, the cable cover is attached to the control box by several screws, which makes assembly and disassembly not only cumbersome and time-consuming, but also prone to screw loss during handling and requires the use of tools. Therefore, improving the locking mechanism between the cable cover and the control box to allow for easier assembly and disassembly remains a problem that needs to be addressed.

[0005] In view of the above disadvantages, the inventor, based on his expert knowledge and careful research, proposes this revelation to solve the problems of the related field. SUMMARY OF THE INVENTION

[0006] The present disclosure provides a box structure with a semi-automatic spring-loaded hinged lid that utilizes a bidirectional spring bolt. The front spring bolt is inserted into a hollow opening in the box base, and the rear spring bolt rests against an inclined surface. When the front spring bolt is pushed out of the through-hole, it compresses an elastic element, and the elastic return of the element drives the rear spring bolt, causing it to move upward along the inclined surface and thereby opening the top cover relative to the box base. This configuration enables the box structure with semi-automatic spring-loaded hinged lid to be easily assembled and disassembled, as well as to provide a semi-automatic opening function.

[0007] This disclosure provides a box structure with a semi-automatic spring-loaded hinged lid, comprising a box base having an outer circumferential wall, a recessed section, and a front inner wall and a rear inner wall formed within the recessed section. The front inner wall has a through-hole penetrating the outer circumferential wall. The rear inner wall has an inclined surface that gradually increases the distance from the front inner wall in an upward direction. A top cover is configured to cover the box base accordingly. The top cover has a through-hole. A bidirectional spring bolt is inserted through the through-hole and received in the recessed section. The bidirectional spring bolt includes a front spring bolt and a rear spring bolt exposed at both ends of the through-hole and is retractable with respect to the through-hole.An elastic element is held between the front and rear spring bolts. The front spring bolt is inserted into the through-hole. The rear spring bolt rests against the inclined surface. When the front spring bolt is pushed out of the through-hole, the elastic element is compressed, and its elastic return propels the rear spring bolt upwards along the inclined surface, causing the top cover to spring open relative to the box base.

[0008] Accordingly, the present disclosure employs a bidirectional spring bolt, wherein the front spring bolt is inserted into a through-hole and the rear spring bolt rests against an inclined surface. When the front spring bolt is pushed inwards, it retracts from the through-hole while the elastic element is compressed. The elastic return of the elastic element drives the rear spring bolt, which in turn moves upwards along the inclined surface, generating an upward force that causes the top cover to spring open relative to the box base. This configuration allows the box structure with a semi-automatic spring-loaded hinged lid to be easily assembled and disassembled and to perform a semi-automatic opening function.Furthermore, since the mechanism relies primarily on the elastic deformation of the elastic element under compression, the front and rear spring bolts are less susceptible to deformation, thus ensuring the structural stability of the box structure with semi-automatic hinged lid of this revelation.

[0010] In connection with the present disclosure, it should be noted that the terms "front(s)," "rear(s)," "left," "right," "front end," "rear end," "remote end," "longitudinally," "laterally," "vertically," "above," "below," and similar directional or positional expressions are based on the orientations or positional relationships shown in the drawings. These terms are used solely for the convenience of description and to simplify the disclosure and are not intended to indicate or imply that the device or components must be constructed or operated in a particular orientation. Accordingly, these terms should not be considered as limiting the present disclosure.

[0011] The technical details of this disclosure will become apparent below through a detailed description of the embodiments accompanied by illustrations of the associated drawings. It is intended that the embodiments and drawings disclosed herein should be considered illustrative and not limiting.

[0012] Now, the focus will shift to... Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12 to Fig. Reference is made to Figure 13. The present disclosure provides a box structure with a semi-automatic spring-opening hinged lid. The box structure 10 with semi-automatic spring-opening hinged lid mainly comprises a box base 1, a top cover 2 and a bidirectional spring bolt 3.

[0013] As in Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12 to Fig. As shown in Figure 13, the box base 1 has an outer circumferential wall 11, a recessed section 12, and a front inner wall 13 and a rear inner wall 14 formed in the recessed section 12. The front inner wall 13 is provided with a hollow opening 131 that penetrates the outer circumferential wall 11. The hollow opening 131 is a conical hole, its circumferential dimension gradually increasing in the direction towards the outer circumferential wall 11. The rear inner wall 14 has an inclined surface 141 that gradually increases the distance from the front inner wall 13 in an upward direction.

[0014] Furthermore, the box base 1 has a first locking element 15, wherein the first locking element 15 forms a lower inclined surface 151 at its lower edge, the thickness gradually decreasing in the downward direction. The box base 1 is also provided with a slot 16, from the inner circumference of which the first locking element 15 projects.

[0015] Furthermore, in this embodiment, the box base 1 serves as a control box configured to connect to lines 200 of an actuator; however, the disclosure is not limited to this. The outer perimeter wall 11 is provided on its front side with a wiring area 111 and several plug holes 112 installed in the wiring area 111. Each of the plug holes 112 is used for electrical connection to a corresponding line 200. The box base 1 also has a raised section 17 projecting upwards, and several control switches 171 are provided on the upper surface of the raised section 17. The several control switches 171 are electrically connected to the several plug holes 112 such that switching the control switches 171 back and forth controls the operation or deactivation of the actuator.

[0016] As in Fig. As shown in Figures 1 to 13, 7, 8, 10, and 12, the upper cover 2 is configured to open and close relative to the box base 1. The upper cover 2 is provided with a through-hole 21. A spring-loaded locking arm 22 extends downwards from the upper cover 2, and a second locking element 221 extends from the far end of the spring-loaded locking arm 22. The second locking element 221 forms an upper inclined surface 222 at its upper edge, the thickness of which gradually decreases upwards.

[0017] Furthermore, in this embodiment, the upper cover 2 is a U-shaped cover 24 that surrounds one side of the raised section 17, but this is not limited to that. The upper cover 2 also extends with a limiting plate 23 that is arranged above the wiring area 111. Several limiting joints 231 are formed at the lower edge of the limiting plate 23. When the upper cover 2 is closed with respect to the box base 1, annular projections formed on the outer circumferences of the conductors 200 engage with the limiting joints 231 and are positioned by the limiting plate 23, thus preventing the conductors 200 from becoming detached from their respective sockets 112.

[0018] Furthermore, either the box base 1 or the upper cover 2 is provided with one or more pivot holes 4, and the other pivot hole of the box base 1 and the upper cover 2 extends with one or more pivot shafts 5. The pivot shafts 5 are rotatably coupled to the pivot holes 4. In this embodiment, the pivot holes 4 are formed on the upper cover 2, and the pivot shafts 5 extend from the raised portion 17 of the box base 1, but this is not limited to this configuration. Alternatively, the pivot holes 4 can be formed on the box base 1, and the pivot shafts 5 can extend from the upper cover 2.

[0019] As in Fig. As shown in Figures 1-5, the bidirectional spring bolt 3 is inserted through the through-hole 21. The bidirectional spring bolt 3 comprises a front spring bolt 31, a rear spring bolt 32, an elastic element 33, and a sleeve 34. The sleeve 34 is firmly inserted into the through-hole 21, and the outer circumference of the sleeve 34 has a lamellar structure 341 that is pressed into and thus engages with the inner circumference of the through-hole 21. One end of the front spring bolt 31 and one end of the rear spring bolt 32 are inserted into the sleeve 34, and the other ends of the front spring bolt 31 and the rear spring bolt 32 are exposed at opposite ends of the sleeve 34.The elastic element 33 is held between the front spring bolt 31 and the rear spring bolt 32, such that the front spring bolt 31 and the rear spring bolt 32 protrude from opposite ends of the through hole 21 and are retractable with respect to the through hole 21.

[0020] Furthermore, the front spring bolt 31 and / or the rear spring bolt 32 are provided with a receiving hole 35 for receiving and positioning the elastic element 33. In this embodiment, the receiving hole 35 is formed on the rear spring bolt 32, but this disclosure is not limited to this. Alternatively, the receiving hole 35 can be formed on the front spring bolt 31. Preferably, the elastic element 33 is implemented as a helical spring, but this is not limited.

[0021] Furthermore, in this embodiment, the pivot holes 4 and the pivot shafts 5 are arranged on the rear side of the upper cover 2. The recessed section 12 and the slot 16 are located at the left and right ends of the front side of the box base 1, respectively. The bidirectional spring bolt 3 and the spring-loaded locking arm 22 are located at the left and right ends of the front side of the upper cover 2, respectively.

[0022] As in Fig. 4, Fig. 5 to Fig. As shown in Figure 6, in a state of use of the box structure 10 with semi-automatic spring-opening hinged lid of the present disclosure, when the upper cover 2 is closed with respect to the box base 1, the bidirectional spring bolt 3 is received in the recessed section 12, the front spring bolt 31 is inserted into the hollow opening 131, and the rear spring bolt 32 rests against the inclined surface 141. The spring-loaded locking arm 22 is also received in the slot 16, the second locking element 221 is engaged below the first locking element 15, and the lower inclined surface 151 rests against the upper inclined surface 222.

[0023] As in Fig. 7, Fig. 8, Fig. 9, Fig. 10 to Fig.Figure 11 illustrates another use state of the box structure 10 with semi-automatic spring-opening hinged lid of the present disclosure. After the upper cover 2 has been closed relative to the box base 1, a user can, for example, insert a rod-shaped element 100, such as a hand tool, into the hollow opening 131 to push the front spring bolt 31. When the front spring bolt 31 is pushed inwards, it disengages from the hollow opening 131, while simultaneously the elastic element 33 is compressed. The elastic return of the elastic element 33 can push the rear spring bolt 32, driving it to move upwards along the inclined surface 141, generating an upward force. As a result, the bidirectional spring bolt 3, together with the upper cover 2, is displaced relative to the box base 1.Meanwhile, the generated upward force causes the lower inclined surface 151 and the upper inclined surface 22 to slide relative to each other, and induces an elastic deformation of the spring-loaded locking arm 22, such that the second locking element 221 is released from the first locking element 15, thereby enabling the upper cover 2 to spring open automatically with respect to the box base 1 and achieving a semi-automatic spring-opening function.

[0024] Accordingly, conventional cable protection covers are secured to a control box by several screws, resulting in cumbersome and time-consuming assembly and disassembly, or are completely secured to the control box by snap-fit ​​structures that are prone to breakage and deformation. In contrast, the present disclosure employs the bidirectional spring bolt 3, wherein the front spring bolt 31 is inserted into the hollow opening 131 and the rear spring bolt 32 rests against the inclined surface 141. When the front spring bolt 31 is pushed inwards and released from the hollow opening 131, the elastic element 33 is simultaneously compressed.The elastic return of the elastic element 33 can push the rear spring bolt 32 and further drive the rear spring bolt 32 such that it moves upwards along the inclined surface 141, generating an upward force that allows the upper cover 2 to spring open relative to the box base 1. As a result, the box structure 10 with semi-automatic spring-opening hinged lid of the present disclosure achieves ease of assembly and disassembly and implements a semi-automatic spring-opening function. Since the process is also achieved primarily by elastic deformation of the elastic element 33, the front spring bolt 31 and the rear spring bolt 32 are less susceptible to compression deformation, further providing the box structure 10 with semi-automatic spring-opening hinged lid with improved structural stability.

[0025] Although this disclosure has been described by means of specific embodiments, the person skilled in the art can make numerous modifications and changes to it without deviating from the scope and the inventive concept of this disclosure as set out in the claims.
