Description

Technical Field

[0001] The utility model relates to the technical field of optical lenses, in particular to a grating lens fixing bracket. Background Art

[0002] Safety light curtain is a photoelectric safety protection device, which is composed of a transmitter and a receiver. The transmitter transmits a set of infrared light beams, and the receiver includes many light sensors. If an object is between the transmitter and the receiver, the receiver cannot receive the complete signal and will send a stop signal to the monitoring device. The light beams sent by the safety light curtain transmitter are sequential and sent at a specific frequency. The detector can only receive specific pulses of a specific frequency sent by the transmitter, thus avoiding the influence of other infrared light sources and improving the applicability in the security system. Standards The following are some standards related to safety light curtains:

[0003] ANSI B11.19 IEC61496-1 / -2IEC / TS 62046ISO13855(EN 999). Safety light curtains can be classified as presence detection devices. Other common presence detection devices are pressure-sensitive safety mats and laser scanners (commonly used in remote control vehicles for industrial applications). The main application of most industrial safety relays is in workstations with robots. The safety light curtain is connected to the safety relay, and if an object is detected, it will automatically remove the power source that will cause harm. In conjunction with the safety relay, the function of the safety light curtain can also be temporarily suspended, allowing objects to pass through the safety light curtain without generating a protection signal. This is suitable for some semi-automated processes. By reasonably reducing the need for physical protection, safety light curtains simplify routine tasks such as equipment installation, maintenance and repair.

[0004] The grating is composed of a grating lens and a bracket for fixing the grating lens. In the prior art, the fixing bracket of the grating lens is installed in a profile (aluminum profile or aluminum alloy profile) with an assembly gap (in order to ensure the convenience of assembly, there is a certain assembly gap between the fixing bracket of the grating lens and the profile). The problem is that in a high impact and vibration environment, there will be looseness between the fixing bracket of the grating lens and the profile. This looseness may affect the working effect and reliability of the grating, and may even cause the grating to fail. Utility Model Content

Unless otherwise specified, "plurality" means two or more.

[0027] Unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.

[0028] like Figure 1 As shown, an embodiment of the present application provides a grating lens fixing bracket, including a bracket body 1, and a mounting hole 2 arranged on the bracket body 1 for assembling the grating lens, and also includes a fixing structure 3 arranged on both side walls of the bracket body 1.

[0029] In this embodiment, the bracket body 1 is provided with mounting holes 2, wherein the number of the mounting holes 2 may be 4, and grating lenses may be mounted on the mounting holes 2, thereby facilitating the installation of the grating lenses. The fixing structures 3 are arranged on both side walls of the bracket body 1. Specifically, the fixing structures 3 are distributed around both sides of the mounting holes 2 and are symmetrically distributed. By providing the fixing structures 3 and clamping with the profile (aluminum profile or aluminum alloy profile), after the fixing bracket is installed in the profile, when the grating is working, it is possible to prevent the grating lens fixing bracket and the profile from loosening under high impact vibration, thereby avoiding the working effect and reliability of the grating.

[0030] Optional, such as Figure 1 and Figure 3 As shown, the fixing structure 3 includes upper and lower fixing parts 31 arranged on the two side walls of the bracket body 1, hook parts 32 arranged on both sides close to the end of the bracket body 1, and left and right fixing parts 33 arranged on the hook parts 32.

[0031] In this embodiment, the upper and lower fixing parts 31 are arranged at the two side walls of the bracket body 1 and are symmetrically distributed. The upper and lower fixing parts 31 are strip-shaped and elastic, and can be understood as spring sheets, which are fixedly connected to the two side walls of the bracket body. By setting the upper and lower fixing parts 31, it is possible to prevent the fixed bracket from shaking or vibrating up and down when installed in the profile. At the same time, the hook part 32 is arranged at both sides of the end position of the bracket body 1, and the end is fixedly connected to the upper and lower fixing parts 31, and at the same time, one end of the left and right fixing parts 33 is fixedly connected to the end of the hook part 32. It should be noted that the upper and lower fixing parts 31, the hook part 32 and the left and right fixing parts 33 are all elastic and have barbs at the free ends. Therefore, when the fixed bracket is installed in the profile, it can be clamped, thereby preventing loosening in a high vibration environment.

[0032] Further, such as Figure 2 and Figure 4 As shown, the bottom surfaces of the upper and lower fixing parts 31 are further provided with first clamping hooks 311 for fixing with external profiles.

[0033] In the present embodiment, the bottom surface of the upper and lower fixing parts 31 is further provided with a first snap-fitting hook 311. Specifically, the snap-fitting hook is fixedly connected to and perpendicular to the bottom surface of the upper and lower fixing parts 31, so that it can be installed on the profile to prevent the present embodiment from shifting, thereby enabling better snap-fitting and preventing the present embodiment from loosening.

[0034] Optional, such as Figure 1 As shown, the two side walls of the end of the bracket body 1 away from the hook portion 32 are further provided with a limiting portion 11 for engaging with the hook portion 32 .

[0035] In this embodiment, the above-mentioned limiting portion 11 is arranged on the bracket body 1 and is away from one end of the hook portion 32, and is relatively distributed, so that when the fixed brackets are spliced ​​with each other, the hook portions 32 and the limiting portion 11 on the adjacent fixed brackets can be engaged, thereby preventing the fixed brackets from loosening when splicing. The above-mentioned limiting portion 11 is in the shape of two protrusions, so that the barbs of the above-mentioned hook portion 32 can be easily engaged with them, thereby preventing loosening.

[0036] In a possible embodiment, a limiting groove can be set on the above-mentioned bracket body 1 and at one end away from the hook portion 32. The limiting groove is provided to cooperate with the hook portion 32. Specifically, the limiting groove has a concave hole that can be mutually engaged with the hook portion 32. Therefore, when two adjacent fixed brackets are spliced, the two adjacent fixed brackets can be mutually engaged, thereby preventing the two fixed brackets from loosening.

[0037] Optional, such as Figure 1 and Figure 2 As shown in the figure, one end of the bracket body 1 is provided with a limiting protrusion 12, and the other end is provided with a limiting recess 13. When two grating lens fixing brackets are spliced, the limiting protrusion 12 is inserted into the limiting recess 13.

[0038] In this embodiment, the limiting protrusion 12 is arranged at one end of the bracket body 1. Specifically, the limiting protrusion 12 is arranged on the bracket body 1 and is close to one end of the hook portion 32, and the limiting recess 13 is arranged on the bracket body 1 and is close to one end of the limiting portion 11, so that when the fixing brackets of the two grating lenses are spliced ​​with each other, the limiting protrusion 12 can be inserted into the limiting recess 13, so that they can be better spliced, thereby preventing the two fixing brackets from loosening.

[0039] In a possible embodiment, the above-mentioned limiting recess 13 can also be set on the bracket body 1 and close to one end of the hook portion 32, and the limiting protrusion 12 can be set on the bracket body 1 and close to one end of the limiting portion 11, so that when the two fixed brackets are spliced ​​together, the limiting recess 13 can also be plugged and matched with the limiting protrusion 12, thereby preventing the two fixed brackets from loosening.

[0040] Optional, such as Figure 1 or Figure 3 or Figure 4 As shown, second clamping hooks 4 are provided on both sides of the opening of the bracket body 1 close to the mounting hole 2 for fixing each grating lens to each of the mounting holes 2 .

[0041] In the present embodiment, the second snap-fitting barbs 4 are mounted on the bracket body 1. Specifically, the second snap-fitting barbs 4 are distributed on both sides close to the mounting holes 2, wherein each mounting hole 2 corresponds to two second snap-fitting portions, so that the grating lens can be assembled and fixed on the mounting hole 2, thereby preventing the grating lens from loosening with the bracket body 1.

[0042] Optional, such as Figure 1 , Figure 2 and Figure 3 As shown, light guide holes 5 are provided on the bracket body 1 and around the two sides of the mounting hole 2 for inserting light guide columns.

[0043] In this embodiment, the light guide holes 5 are installed on the bracket body 1 and are distributed around the two sides of the mounting hole 2. Specifically, there are two light guide holes 5. By setting the light guide holes 5, it is convenient to insert the light guide column therein, so that it is easy to view the indicator light source emitted by the light guide column.

[0044] Optionally, the bracket body 1 and the fixing structure 3 are integrally formed.

[0045] In this embodiment, by configuring the support body 1 and the fixing structure 3 as an integrated molding structure, it is possible to facilitate casting and make the structure of this embodiment more solid, thereby enriching this embodiment.

[0046] Optionally, the bracket body 1 and the fixing structure 3 are made of one of heat-resistant plastic, metal, glass fiber reinforced plastic and silicone.

[0047] In this embodiment, the bracket body 1 and the fixed structure 3 can be set to one of heat-resistant plastic, metal, glass fiber reinforced plastic and silicone. Specifically, taking the bracket body 1 and the fixed structure 3 as heat-resistant plastic as an example, it can save production costs. Since the grating will generate a certain amount of heat, setting the fixed structure 3 to heat-resistant plastic is helpful to prevent the fixed bracket from melting at high temperatures. At the same time, the plastic has a certain elasticity, so that when the present embodiment is installed in the profile, it can produce elastic deformation, so that the present embodiment can be better clamped with the profile to prevent it from loosening.

[0048] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
