Description

Technical Field

[0001] This utility model relates to the technical field of chassis and equipment fixing devices, and in particular to a small fixing block assembly that can be rotated and locked. Background Technology

[0002] With the continuous development of electronic test equipment and enclosure systems, various test instruments and receivers need to be flexibly installed and fixed within cabinets. In modern test cabinet systems, to meet different testing needs and space layout requirements, various electronic devices and test modules need to be able to be quickly and accurately positioned and fixed in designated locations. As a key component for achieving precise positioning and reliable fixation of equipment, the structural design of the fixing block directly affects the installation efficiency, ease of use, and space utilization of the entire test system. Especially in enclosure equipment with sliding drawers, due to space constraints and operational convenience requirements, the fixing block needs to be compact, flexible in operation, and accurate in positioning.

[0003] In existing chassis mounting technologies, traditional mounting blocks typically employ a single fixing method: either completely rigid or a simple detachable structure. These traditional solutions reveal several limitations in practical applications. First, existing mounting blocks lack flexible position adjustment capabilities. When changing equipment layout or performing maintenance operations, complete disassembly of the mounting component is often required, which is cumbersome and time-consuming. Second, traditional fixing methods struggle to balance reliable locking during use and compact storage when not in use. They either occupy excessive space when not in operation or suffer from loosening and wobbling, affecting the overall system stability. Furthermore, the mounting block structure in existing technologies is relatively complex, requiring multiple independent components to achieve rotation, positioning, and locking functions. This not only increases manufacturing costs and assembly complexity but also reduces applicability within confined chassis spaces.

[0004] Therefore, how to design a compact, easy-to-operate, flexible, and reliably lockable small fixing block structure that can be effectively stored and fixed in the non-working state is a technical problem that urgently needs to be solved in the field of chassis and equipment fixing devices. Utility Model Content

[0005] The technical problem to be solved by this utility model is to address the existing problems of complex structure, cumbersome operation, lack of flexible position adjustment capability, and inability to be effectively stored and fixed in non-working state of the chassis fixing block. The present invention provides a small fixing block assembly that is compact in structure, easy to operate, and capable of flexible rotation adjustment and reliable locking.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A rotatable and lockable small retaining block assembly, comprising:

[0008] The fixing block body has a first through hole and a second through hole, and the upper surface of the fixing block body has a recess.

[0009] A rotating shaft assembly, which passes through the first through hole, is used to connect to the receiver, allowing the fixed block body to rotate about its axis.

[0010] A locking component, inserted through the second through hole, is used to fix the fixing block body to the test cabinet;

[0011] The storage component includes an elastic positioning element. When the fixing block body is rotated to a preset position, the elastic positioning element cooperates with the recess to position the fixing block body through elastic holding action.

[0012] Preferably, the rotating shaft assembly is a first screw, and the fixed block body can rotate around the first screw at an angle range of 0-90°.

[0013] Preferably, the locking component is a second screw, which passes through a second through hole and connects to the test cabinet.

[0014] Preferably, the first screw is a push-button screw and the second screw is a pan head cap screw.

[0015] Preferably, the elastic positioning element is a ball set screw, which is installed on the receiver, with the steel ball at its head acting as an elastic positioning element and engaging with the recess.

[0016] Preferably, the center distance between the first through hole and the second through hole is a preset distance.

[0017] Preferably, the recess is a circular recess, located between the first through hole and the second through hole.

[0018] The beneficial effects that this utility model can achieve are:

[0019] By setting a first through hole and a second through hole on the fixed block body, and configuring the first screw of the rotating shaft assembly to pass through the first through hole to realize the rotation fulcrum, and the second screw of the locking assembly to pass through the second through hole to realize the working lock, an integrated rotation positioning and fixing system is formed. This system realizes flexible rotation adjustment and reliable locking of the fixed block on the same body, solves the problems of complex structure, cumbersome operation and large space occupation of existing fixed blocks, and significantly improves the compactness of structure, ease of operation and space utilization.

[0020] By setting an elastic pre-positioning mechanism in which the third screw of the storage component engages with the recessed upper surface of the fixing block, combined with the rigid locking mechanism of the second screw of the locking component, a two-level fixing system is formed. This achieves stable storage in the non-working state and reliable locking in the working state, solving the problem that the fixing block cannot be effectively stored and fixed in the non-working state. This ensures both ease of operation and stability under different usage conditions.

[0021] By allowing the fixed block body to rotate freely within a 90° range around the first screw, combined with the small block structure design, a flexible position adjustment system is formed, realizing rapid position switching and precise positioning within a limited space. This solves the problems of inflexible fixed block position adjustment and cumbersome maintenance operations in the prior art, and significantly improves the flexibility of equipment layout and maintenance efficiency.

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments, but these specific embodiments do not limit the scope of protection of the present invention in any way. Example

[0029] like Figure 1-5 As shown, a rotatable and lockable small fixing block assembly of the present invention includes a fixing block body 1, a rotating shaft assembly 2, a locking assembly 3, and a storage assembly 4.

[0030] See Figure 3 ,and Figure 4 The aforementioned fixing block body 1 is made of SUS630 material and has a small block structure with external dimensions of 47.5mm×14mm×13mm. The fixing block body 1 has two through holes, namely a rotating shaft hole 11 and a locking hole 12, with a center distance of 33.5mm between the two holes. The upper surface of the fixing block body 1 has a 1mm deep recess 13, which is used to cooperate with the storage component 4 to achieve positioning and fixation in the non-working state.

[0031] See Figure 2- Figure 4 The aforementioned rotating shaft assembly 2 includes a hex socket head cap screw 21 with a specification of Ø6×8-M5, and a hex socket head cap bead set screw 41 with a specification of M6×8. The hex socket head cap screw 21 passes through the rotating shaft hole 11 on the fixing block body 1 and engages with the threaded hole on the receiver 5 to form a rotating shaft fulcrum, allowing the fixing block body 1 to rotate freely around the axis, with a rotation angle range of 0° to 90°.

[0032] The aforementioned locking component 3 is a cross-head pan head cap screw 31 with a specification of M5×20. The locking component 3 passes through the locking hole 12 on the fixing block body 1 and is used to firmly lock the fixing block body 1 onto the test cabinet 6 in the working state, so as to achieve reliable rigid fixation.

[0033] The aforementioned storage component 4 is an internal hexagonal glass ball set screw 41 with a specification of M6×8. The storage component 4 is set in the storage position of the fixing block body 1. The steel ball inside can be inserted into the recess 13 on the upper surface of the fixing block body 1 under elastic action, so as to elastically pre-position and fix the fixing block body 1 in the non-working state, and prevent the fixing block body 1 from shaking when not in use.

[0034] The working principle and method of this utility model's rotatable and lockable small fixing block assembly are as follows:

[0035] In actual use, the fixing block body 1 is first connected to the receiver 5 through the internal hexagon socket screw 21 in the rotating shaft assembly 2. At this time, the fixing block body 1 is in a state of free rotation.

[0036] Specifically, when adjusting the position, the user can directly turn the fixing block body 1 by hand, allowing it to rotate freely around the hex socket head cap screw 21 inside the rotating shaft hole 11. Due to the precise fit clearance between the rotating shaft hole 11 and the hex socket head cap screw 21, the fixing block body 1 can rotate smoothly within the range of 0° to 90° without any jamming. When the fixing block body 1 rotates to the desired working position, the rotation operation is stopped, at which point the fixing block body 1 has achieved initial positioning.

[0037] After the fixing block body 1 is adjusted to the appropriate working position, the cross-head pan head captive screw 31 in the locking assembly 3 is inserted through the locking hole 12, screwed into the corresponding threaded hole of the test cabinet 6, and tightened, thereby firmly locking the fixing block body 1 onto the test cabinet 6. Due to the captive screw design, the locking screw will not completely detach from the fixing block body 1, avoiding the problem of screw loss, and ensuring reliable locking in the working state.

[0038] When the fixing block is not needed, first loosen the cross-head pan head cap screw 31 in the locking hole 12 to separate the fixing block body 1 from the test cabinet 6. Then rotate the fixing block body 1 to the initial storage position. At this time, the hex socket head cap screw 41 in the storage assembly 4 will play its role. The steel ball inside will automatically lock into the recess 13 on the upper surface of the fixing block body 1 under the pressure of the spring, realizing elastic positioning and fixing in the storage state, and preventing unnecessary rotation or shaking of the fixing block body 1 when it is not in operation.

[0039] Furthermore, throughout the entire rotation and locking process, the fixing block body 1 remains connected to the receiver 5, allowing for a quick switch from the storage state to the working state with just simple rotation and screw operations. Because the fixing block body 1 employs a small, block-like structure design, its compact size ensures flexible operation even in confined chassis spaces, without interfering with other equipment.

[0040] Furthermore, the flexible pre-positioning function of the storage component 4 and the rigid locking function of the locking component 3 work together to form a two-level fixing mechanism. In the non-working state, the flexible pre-positioning provides moderate fixing force, which can prevent accidental rotation and facilitate user position adjustment; in the working state, the rigid locking provides strong fixing force to ensure that the fixing block will not shift or loosen when subjected to external forces.

[0041] In summary, the advantages of this invention lie in its integration of rotation, positioning, and locking functions onto a single fixing block body 1, achieving a high degree of structural integration. Compared to traditional fixing schemes requiring multiple independent components, this invention features a more compact structure and more convenient operation. Users can quickly adjust the working position of the fixing block according to actual needs, significantly improving flexibility and operational efficiency.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any innovative improvements or substitutions based on this utility model should fall within the scope of the claims of this utility model. Furthermore, the parameters, materials, and processes mentioned in the above embodiments are not unique. Without departing from the technical essence of this utility model, those skilled in the art can make various alternative choices, and these alternative solutions should also be considered to fall within the scope of protection of this utility model.
