Description
Technical Field
[0001] This utility model relates to the field of power safety facilities technology, and more specifically, to a fence device that is easy to assemble and disassemble. Background Technology
[0002] Fence devices are widely used in power construction and many other scenarios requiring isolation and protection. Existing fence devices typically employ a specific base and fence body connection structure for installation and disassembly. Currently, the most common fence base and connection part uses a nested structure for installation and disassembly. When installing the fence base, the operator needs to accurately align the fence connection with the base hole, then push downwards to fix the fence body onto the base. When disassembling the fence base, it is usually necessary to press the fence base firmly with both feet to fix its position, then shake the fence left and right while applying upward force until the fence body (the connection with the base) is pulled out of the base.
[0003] However, this traditional nested fence connection structure has many problems. On the one hand, the entire installation and dismantling process is cumbersome, time-consuming, and labor-intensive, resulting in a significant waste of human resources and reduced work efficiency. This problem is particularly prominent in construction scenarios that require frequent installation and dismantling of fences, seriously affecting the construction progress.
[0004] On the other hand, due to the unreasonable design of the connection between the fence and the base, as well as the embedded structure of the base holes, the components at the connection between the fence and the base, and the base itself, will experience a certain degree of wear as the fence is installed and disassembled repeatedly. This wear not only further increases the difficulty of installation and disassembly but also significantly reduces the service life of the fence device, increasing equipment replacement costs.
[0005] In addition, the existing fence connection structure also has certain defects in terms of stability. It is prone to loosening due to external forces or long-term use, which affects the protective performance of the fence device and poses certain safety hazards.
[0006] Meanwhile, the existing connection structure between the fence base and the fence body has poor adaptability to the installation environment. When encountering uneven ground or other special terrain, it is difficult to guarantee the stability and firmness of the fence installation, which further limits its application range.
[0007] Moreover, the disassembly and assembly process of existing fencing devices also requires a certain level of technical proficiency from the operators. New operators often need a certain amount of practice to master the disassembly and assembly skills, which brings many inconveniences to actual use.
[0008] In summary, existing fence base and fence interface designs have significant shortcomings in terms of ease of installation and disassembly, service life, stability, and environmental adaptability. Therefore, there is an urgent need for a fence base and fence interface design that is easy to disassemble and install to solve the above problems and meet the practical application requirements for fence devices that are efficient, durable, stable, and easy to operate. Utility Model Content
[0009] The present invention aims to solve at least one of the aforementioned technical problems existing in the prior art.
[0010] Therefore, this utility model provides a fence device that is easy to assemble and disassemble.
[0011] The present invention proposes a fence device that is easy to assemble and disassemble, comprising a fence body and a fence base. The bottom of the fence body is provided with a connecting foot, which is detachably connected to the fence base. The connecting foot has at least one protruding structure, and the arrangement direction of the protruding structure is perpendicular to the assembly direction of the connecting foot and the fence base.
[0012] The fence base includes an elastic structure and a first groove, a second groove, and a third groove arranged sequentially from bottom to top and connected to each other; the elastic structure is disposed in the first groove, one end of which is connected to the bottom surface of the first groove, and the other end has an elastic degree of freedom; the connecting foot can abut against the elastic structure through the third groove, the second groove, and the first groove in sequence;
[0013] The distance from the center of the connecting foot to the outer edge of the protruding structure is defined as the first length. Half of the diameter of the first groove is less than the first length, and half of the diameter of the second groove is greater than the first length. The third groove matches the shape of the protruding structure so that the protruding structure can only enter the second groove through the third groove when it is rotated to a specified direction.
[0014] The protruding structure has a degree of freedom to rotate within the second groove about the axis of the connecting foot, and when it rotates to a position that does not overlap with the third groove, it abuts against the groove wall of the second groove under the elastic force of the elastic structure.
[0015] The easily detachable fence device according to the above-described technical solution of this utility model may also have the following additional technical features:
[0016] In the above technical solution, there are two protruding structures, which extend outward along the radial direction of the connecting foot, and the two protruding structures are symmetrically arranged on both sides of the connecting foot.
[0017] In the above technical solution, the distance between the outer edges of the two protruding structures is defined as the second length, the groove diameter of the first groove is less than the second length, and the groove diameter of the second groove is greater than the second length.
[0018] In the above technical solution, the number of the third grooves matches the number of the protrusions.
[0019] In the above technical solution, the minimum vertical distance between the protruding structure and the bottom of the connecting foot is defined as the third length;
[0020] The vertical distance between the highest vertex of the elastic structure in its free state and the interface between the first and second grooves is defined as the fourth length.
[0021] The third length is greater than the fourth length.
[0022] In the above technical solution, the first groove is a cylindrical groove;
[0023] The second groove is an annular groove.
[0024] In the above technical solution, the end of the connecting foot adopts a spherical structure or a near-spherical structure;

[0026] The above technical solution also includes a fourth groove;
[0027] The fourth groove is disposed above the third groove, and half of the diameter of the fourth groove is greater than the first length.
[0028] In the above technical solution, the elastic structure includes:
[0029] The abutment block has an abutment surface for abutting against the end of the connecting leg;
[0030] One end of the spring is fixedly connected to the bottom surface of the first groove, and the other end is fixedly connected to the abutment block.
[0031] In the above technical solution, the width of the second groove is greater than 1.2 times the thickness of the protrusion structure.
[0032] In summary, due to the adoption of the above-mentioned technical features, the beneficial effects of this utility model are:
[0033] The fence device proposed in this utility model changes the previous method of installing and dismantling fences by using brute force. By changing the connection structure between the fence body and the base to a spring-compression type, the labor and time consumption is greatly reduced. In terms of recycling, it reduces the nesting and compression between the fence body and the base, reduces wear and tear on the contact between the fence body and the base, and extends the service life of the fence.
[0034] Specifically, this invention avoids the time-consuming and laborious process of installing or disassembling the fence base, increasing the efficiency of workers. The use of an elastic structure greatly reduces the upward force required during disassembly. (During disassembly, press down on the fence body and rotate the base so that the protruding structure above the connection between the fence body and the base aligns with the corresponding pre-drilled hole below. Once the protruding structure passes through the corresponding pre-drilled hole, release the pressure to use elastic potential energy to separate the base from the fence body). During installation, the base direction can also be selected according to the actual working conditions (during installation, rotate the base so that the protruding structure above the connection between the fence body and the base aligns with the corresponding pre-drilled hole below, press down on the fence body, and once the protruding structure passes through the corresponding pre-drilled hole, rotate the base again and release the pressure; the same method achieves a fixed connection between the fence body and the base). At the same time, the structural design at the connection between the base and the fence provides sufficient slack, reducing wear on the contact surface and extending its service life.
[0035] Additional aspects and advantages of this invention will become apparent in the description that follows, or may be learned by practice of this invention. Attached Figure Description

[0046] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0047] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
[0048] The following reference Figures 1 to 5 This invention describes a fence device that is easy to assemble and disassemble, provided according to some embodiments of the present invention.
[0049] Some embodiments of this application provide a fence device that is easy to assemble and disassemble.
[0050] like Figure 1 As shown, the first embodiment of this utility model proposes a fence device that is easy to assemble and disassemble, including a fence body and a fence base 3. The bottom of the fence body is provided with a connecting foot 1, and the connecting foot 1 is detachably connected to the fence base 3. Specifically, in order to facilitate storage and installation and adapt to different terrains, the fence body and the fence base 3 are usually designed separately. This disclosure is also based on this premise and redesigns the assembly method of the two. For the fence body, except for the connection point (not shown in the figure), the traditional fence shape, grid shape, etc. can be used, and there is no limitation here. Similarly, the shape of the fence base 3 can also be arbitrary. It can be redesigned or a traditional shape can be used. The fence base 3 illustrated in this disclosure has two inclined and symmetrically arranged support feet 36 to maintain the overall stability of the device. The surface of the support feet 36 has a pattern for marking and anti-slip purposes.
[0051] In the redesigned assembly structure of this disclosure, the connecting leg 1 has at least one protruding structure 2, and the arrangement direction of the protruding structure 2 is perpendicular to the assembly direction of the connecting leg 1 and the fence base 3. Specifically, the number of protruding structures 2 can also be multiple but not continuous, i.e., they are spaced apart. The assembly direction of the connecting leg 1 and the fence base 3 is vertical, and the arrangement direction of the protruding structure 2 is horizontal.
[0052] like Figures 2 to 4 As shown, the fence base 3 includes an elastic structure 31 and a first groove 32, a second groove 33, and a third groove 34 arranged sequentially from bottom to top and connected to each other; the elastic structure 31 is disposed in the first groove 32, one end of which is connected to the bottom surface of the first groove 32, and the other end has an elastic degree of freedom; the connecting foot 1 can abut against the elastic structure 31 through the third groove 34, the second groove 33, and the first groove 32 in sequence;
[0053] The distance from the axis of the connecting foot 1 to the outer edge of the protruding structure 2 is defined as the first length. Half of the diameter of the first groove 32 is less than the first length, and half of the diameter of the second groove 33 is greater than the first length. The third groove 34 matches the shape of the protruding structure 2 so that the protruding structure 2 can enter the second groove 33 through the third groove 34 when it is rotated to a specified direction.
[0054] With the above configuration, the protruding structure 2 has the freedom to rotate within the second groove 33 about the axis of the connecting foot 1. When it rotates to a position that does not overlap with the third groove 34, it abuts against the groove wall of the second groove 33 under the elastic force of the elastic structure 31. At this time, the connecting foot 1 is locked to the fence base 3. Similarly, when the protruding structure 2 rotates within the second groove 33 to a position that overlaps with the third groove 34, the connecting foot 1 and the protruding structure 2 disengage from the second groove 33 under the elastic force of the elastic structure 31. At this time, the connecting foot 1 can be easily separated from the fence base 3.
[0055] like Figure 5 As shown, there are two protruding structures 2, which extend radially outward along the connecting leg 1. The two protruding structures 2 are symmetrically arranged on both sides of the connecting leg 1. This symmetrical arrangement makes the rotation of the connecting leg 1 and the locking function of the elastic structure 31 more reliable and stable. Of course, a symmetrical arrangement is not necessary for this disclosure. When there are more than two protruding structures 2, such as three, the three protruding structures 2 are evenly arranged around the connecting leg 1, which can also play a stabilizing role.
[0056] based on Figure 5In the embodiment shown, the distance between the outer edges of the two protruding structures 2 is defined as the second length. At this time, the groove diameter of the first groove 32 is less than the second length, and the groove diameter of the second groove 33 is greater than the second length; thus ensuring that the protruding structure 2 cannot enter the first groove 32.
[0057] In some embodiments, the number of the third grooves 34 matches the number of the protrusions 2. It is understood that the number of the third grooves 34 may be greater than the number of the protrusions 2, but not less than the number of the protrusions 2, in order to ensure the smooth separation of the connecting foot 1 from the fence base 3.
[0058] To ensure that the elastic structure 31 reliably provides elastic force for locking or assisting separation between the connecting foot 1 and the fence base 3, the minimum vertical distance between the protruding structure 2 and the bottom of the connecting foot 1 is defined as the third length; the vertical distance between the highest point of the elastic structure 31 in the free state (i.e., the relaxed state, when not compressed) and the interface between the first groove 32 and the second groove 33 is defined as the fourth length; the third length is greater than the fourth length.
[0059] Continue reading Figure 4 In some embodiments, the first groove 32 is a cylindrical groove; the second groove 33 is an annular groove.
[0060] In some embodiments, the end of the connecting leg 1 adopts a spherical or near-spherical structure; the protruding structure 2 is disposed above the spherical or near-spherical structure. This arrangement facilitates maintaining the same force-bearing area with the bottom elastic structure 31 when the fence body is rotated to adjust its direction.
[0061] In some embodiments, a fourth groove 35 is further included; the fourth groove 35 is disposed above the third groove 34, and half of the diameter of the fourth groove 35 is greater than the first length.
[0062] In some embodiments, the elastic structure 31 includes an abutment block 311 and a spring 312.
[0063] The abutment block 311 has an abutment surface for abutting against the end of the connecting leg 1; to improve alignment and smoothness of rotation, the abutment surface can be configured as a concave arc surface that matches the spherical structure; one end of the spring 312 is fixedly connected to the bottom surface of the first groove 32, and the other end is fixedly connected to the abutment block 311 to provide a source of elastic force.
[0064] In some embodiments, the width of the second groove 33 is greater than 1.2 times the thickness of the protrusion structure 2, thereby reducing device wear by maintaining a certain margin.
[0065] Based on the above embodiments, the method of using the fence device proposed in this disclosure is as follows:
[0066] During fence installation: Rotate the fence body or fence base 3 so that the spherical structure at the connection between the fence body and fence base 3 aligns with the elastic structure 31 below. Align the protruding structure 2 on the connecting foot 1 with the corresponding four grooves below, and press down on the fence body. When the protruding structure 2 on the connecting foot 1 enters the second groove 33, rotate the fence body or fence base 3 to adjust the desired direction. Once the direction is determined, release the grip to use the elastic potential energy of the elastic structure 31 to fix the fence body and base in place. If the base direction needs to be changed, follow the same procedure.
[0067] Disassembly stage: Press down on the fence body, rotate the fence body or base so that the protruding structure 2 on the fence body is aligned with the third groove 34, and release to separate the fence base 3 from the fence body by the elastic potential energy of the spring 312.
[0068] In this specification, the illustrative expressions of the terms used do not necessarily refer to the same embodiments or examples. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
[0069] Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model shall be included within the protection scope of this utility model.
